In the framework of the Science and Technology project, a group of researchers from the Faculty of Fisheries (Can Tho University) and graduate student Tran Dong Phuong An, for the first time successfully artificially reproduced freshwater striped fish. The striped fish is a catfish with scientific name (Pangasius macronema), this is a fish with high economic value in the market. Currently, this fish species occurs in the wild quite few and concentrated in provinces such as An Giang, Dong Thap, Vinh Long and Can Tho city. In order to develop the economy, recently, many farmers in some provinces in the upstream of the Mekong River have caught fish in the wild and brought back to raise them in rafts on the Tien and Hau rivers with industrial food for sale. commodity. Currently, striped fish is sold in the market at a high price of 120,000 – 130,000 VND/kg, while in restaurants the price is from 250,000 to 300,000 VND/kg. For the first time, successfully artificially reproduced freshwater striped fish. Photo: Le Hoang Vu. According to the project team, after nearly 4 years of research, this is the first time to successfully stimulate artificial reproduction of striped fish and it is expected that this breed will be replicated and provided to farmers in 2023. This was approved by the City Department of Science and Technology. Sponsored by Can Tho.

Healthy mice were created from freeze-dried sperm stored for 6 years in space. Photo: Teruhiko Wakayama. A new study shows that rat sperm that was freeze-dried and stored on the International Space Station (ISS) for nearly six years didn’t suffer any DNA damage and went on to produce “mice pups” healthy”. The study was published June 11 in the journal Science Advances . According to the scientists, this discovery sheds more light on whether mammals, including humans, can reproduce in space. Combined with ground-based experiments exposing mouse sperm to X-rays, the study found that mammalian sperm cells can be preserved on the International Space Station for up to 200 years. Researchers have long thought that exposure to space radiation can damage the DNA in cells and lead to the possibility of passing mutations on to offspring. The lack of freezers on the ISS has prevented long-term research into living cells. To overcome these limitations, the researchers frozen dried sperm samples from 12 mice and sealed them in small, lightweight tubes and transported to the ISS by rocket without the need for a freezer. Mouse sperm were freeze-dried in glass tubes and stored on the ISS . Photo: Teruhiko Wakayama. Because of the complex mix of different types of radiation in space, scientists say, only simulation experiments to assess DNA damage on Earth cannot capture the reality of conditions. outside our atmosphere. Dr. Sayaka Wakayama, Yamanashi University, Japan, lead author of the study told The Independent : “There are different types of radiation flying around in space, unlike on the ground. For example, there are heavy ions, protons and electromagnetic waves from the rays of the sun.” “It’s very difficult to irradiate and reproduce all these types of radiation at once on the ground, so I think DNA damage in biological samples can only be measured in space,” he explains. . Scientists periodically test small portions of the sample. The samples returned to Earth after 9 months, 2 years 9 months, and 5 years and 10 months, respectively. Mouse embryos developed normally in the laboratory after fertilization with freeze-dried sperm and stored in space. Photo: Teruhiko Wakayama. When the researchers examined the samples using instruments that measured how much radiation they had absorbed and performed tests to assess DNA damage in the cell nuclei, they found a long stay. Long duration on the ISS did not result in DNA damage to freeze-dried sperm. Dr Wakayama said: “The total amount of space radiation absorbed by the ISS, as measured by the Japan Aerospace Exploration Agency (JAXA), is 0.41 milli Gray (mGy) per day. Meanwhile, typical radiation doses used to treat cancers such as solid epithelial tumors range from 60 to 80Gy. “The results of the ground X-ray experiment show that freeze-dried sperm can withstand up to 30 Gy and still be able to produce the next generation,” added Dr Wakayama. The freeze-drying process used in the study is “similar to instant coffee, or freeze-dried fruit,” explains Dr. Wakayama. With food, just adding water can be used “instantly”. The freeze-drying process kills sperm, but when rehydrated and injected into a mouse egg, the sperm can still fertilize the egg, then develop normally. The rehydrated sperm cells, when injected into fresh ovarian cells and transferred to female mice, resulted in the birth of “healthy pups”. Mouse sperm that has been preserved in space for years is injected into egg cells. Photo: Teruhiko Wakayama. Although there is a difference between DNA damage caused by X-rays and space radiation, it can be roughly predicted that freeze-dried sperm can be preserved on the surface of the body, the scientists wrote in the study. ISS for over 200 years”. According to the scientists, a total of 168 mice were born from sperm kept in space for six years, all of which were normal in appearance and had no abnormalities in their gene activity patterns. compared with control mice born from sperm preserved on Earth. Some of these mice were raised to adulthood and were able to produce healthy offspring. Scientists believe that more studies from similar experiments could shed more light on radiation effects and the tolerance of life forms for long periods of time in space. Scientists are also conducting research to find out whether mammalian embryos can develop in zero-gravity conditions. Proposals for this experiment were approved by NASA and JAXA in 2015. In August, frozen mouse embryos will be launched to the ISS, where astronauts will thaw and culture in zero gravity.

Damien Desrocher, 28 years old from the town of Wahagnies, Northern France has a very unique and successful startup method. It is the production of soap bars from snail mucus. Desrocher started using snail mucus to make soap and sell it at the market in the town of Wahagnies, Northern France from December 2020 and received unexpected success. In order to collect a lot of snail mucus, the 28-year-old man had to think of many and extremely ingenious ways not to harm or kill any snails. Damien Desrocher shared: “I only use my fingers to touch the snails, it’s very light and doesn’t hurt them. It looks very simple, all the process depends on your ingenuity.” “Once you observe and see the behavior of snails, you will find they are really adorable. Snails are one of my favorite animals,” says Desrocher. On the feet of snails there is a type of gland that can secrete a very sticky fluid to help them move. Therefore, every place they crawl through leaves a sticky residue. After this sticky fluid dried, a sparkling watery streak was formed. This snail fluid is used to remove wrinkles and acne scars, which is loved by many women because it is really effective. One snail will produce about 2 grams of slime, while to make 15 100-gram Damien Desrocher bars of soap requires about 80 grams of snail mucus. Thus, with only 40 snails, Damien Desrocher was able to produce 15 bars of soap weighing 100 grams. Although novel in the West, snail mucus is a familiar beauty ingredient in Korea because of its anti-aging and skin-restoring properties – including collagen and elastin molecules – in it. The snail itself also uses the slime it secretes to repair the shell when damaged. Currently, Mr. Desrocher has a total of 60,000 snails. When entering the breeding season, most snails will be moved to a larger location to live, in the yard of only about 4,000 snails. With excellent nourishing ingredients, snail mucus helps to stimulate collagen and elastin formation, protect skin from free radicals, soothe skin, repair damaged tissues and restore hydration. It is also added to treat dry skin, wrinkles and stretch marks, acne and rosacea, age spots, burns, scars, razor bumps and even flat warts. The application of snail mucus actually began in ancient Greece, where the father of medicine Hippocrates prescribed snail grinding and yogurt to cure inflammation.

Here are the foods to eat every day to help supplement collagen: Chicken Chicken is rich in amino acids. According to Dr. Bhatia, chicken is rich in non-substituting amino acids that the body needs to produce collagen. Nuts Not only are they rich in healthy fats, nuts also contain high amounts of zinc, which helps support the body in boosting collagen. A food that is both healthy and beautiful for skin and hair. Sweet potato In addition to being a healthier choice than potatoes, sweet potatoes are also rich in beta-carotene, a form of vitamin A. According to Dana Hunnes, a registered dietitian from the UCLA Medical Center, vitamin A is also essential for boosting. collagen enhancement. Garlic In garlic contains sulfur (sulfur) which is an essential substance for the production of collagen in the body. In addition, garlic also contains a compound that brightens eyes, while regenerating damaged collagen. Therefore, you should add garlic to your daily meals in dishes such as stir-frying, cooking, frying … Salmon Salmon contains a large amount of Omega 3 fatty acids that help the skin stay supple and elastic. Therefore, if possible, you should also supplement with salmon every week to promote collagen production and reduce inflammatory areas on the skin. Butter This fruit contains vitamin E and Omega 3 acids that are effective against free radicals, increasing the ability of the skin to produce collagen. So, one cup of avocado smoothie per day is one way to improve the collagen in your skin.

Indian dance ants. The new owner of the throne has the ability to expand the ovaries, reducing the size of the brain to take over the responsibility of reproduction for the whole herd. The battle for the throne Ants have a relatively simple “class” distribution system. While the queen is responsible for laying eggs, the rest of the herd must find food, feed the ants, join the battle, and build nests. Only male ants and queens are capable of reproduction, and other ants cannot. If the queen dies, the whole herd must suffer the same fate. Similarly, the Indian dance ants (Harpegnathos Saltator scientific name) include queens, reproductive males and a group of worker ants who are females. Queen ants hold the highest position in the ant colony, living 5 times longer. Only it is allowed to give birth. In most species of ants, the queen is born, not chosen from a herd. However, the Indian jumping ants allow worker ants to compete for a chance to sit on the throne, becoming a queen ant. Research published in the scientific journal Proceedings of the Royal Society B: Biological Sciences in early April showed that, in this species, if the queen died, about 70% of the female ants in the herd would compete for the throne. . The fight lasted for about 40 days. The opponents used the beard to fight until the competing group had 5 – 10 remaining. These animals continue to spend the next days to reproduce because the ovaries are enlarged while the brain shrinks up to 25%. After the war, the winning child will expand her fertility like a queen and become the second queen. The others return to being a worker, so the ovaries shrink and the brain enlarges again. Professor Clint Penick, the lead author of the study, commented: “This is an unprecedented miracle in the insect world. The toughness of this species allows them to swap roles in the herd. Professor Penick has spent many years studying the Indian dance ants. When worker ants become queen ants, they are called “gamergates”. All worker ants in the herd are capable of reproduction, but they are only allowed to do so when they win the throne. In the natural world, many species of insects, like bees, also compete for dominance. But the jumping ants fight to give birth, which really impressed the scientific experts. When a gamergate becomes a queen, its body goes through a complex transformation process. The queen will stop producing the venom, change its behavior like evading intruders, not hunting. Notably, their brains shrank by 25%, while the ovaries were enlarged by 5%. Indian dance ants can shrink the brain, enlarge the ovaries. Looking for a solution To analyze the queen ant transformation, Penick and his team selected 60 gamergates, painted them to distinguish them, then quarantined them for several weeks. When isolated, gamergate decreased fertility. But when they returned to the herd, they were captured and imprisoned by the worker ants. Penick explains that the gamergates are being controlled by the whole herd. The worker ants stopped the other ants from reproducing because this behavior was beyond the queens of the queen ants. If it was discovered that a member with the same function as the queen ant, the worker ants would bite and detain it for many days even though it did not endanger its life. Scientists hypothesize that this behavior causes a series of internal changes to the gamergates, making them likely to become queen ants but also as worker ants. The transformation happens in a few days. The reason the Indian jumping ant’s brain can shrink is because the gamergate does not have to use the brain to forage, protect the nest from predators. Their main job is to reproduce, while worker ants need large brains to think about these problems. Another reason gamergate shrinks the brain is to conserve energy. This behavior has also been observed in the Etruscan shrew, a small mammal. Their brains shrink in the winter to limit energy, helping to keep other parts of the body warm. Some other animals also have the ability to change brain size such as ground squirrels, birds. White-crested sparrows, for example, create 68,000 new nerve cells during the breeding season to help them recognize mating calls. In winter, when food is scarce, some of the nerve cells die on their own, and in the spring, they revive again. But this phenomenon is rare in insects such as ants. While Rachelle Adams, a researcher in ant evolution and ecology at Ohio State University, thinks maybe this behavior is not as special as we think it is. The problem is that scientists have not fully understood and discovered about the Indian hopping ants may be the foundation for further research in this field. As brain modification is studied more and can be found in many different species, it will have special significance in understanding the human brain. For example, research into the brains of the Indian gerbil helps to understand more about genetic control, the ability of genes to control flexibility in animals and towards humans.

Regular use of scented sprays or soaps can cause gynecological infections (Artwork) Strong alkaline soaps or sprays that are used regularly will cause the vaginal area to be irritated and damaged because this is a very hypersensitive area and leads to the penetration of harmful bacteria. cause vaginitis. Also, soap or shower gel is definitely not the ideal choice when it comes to cleaning your genitals. Because these products often come with chemicals with high alkalinity that easily change the pH concentration inside the vagina, causing irritation to the skin lining of the vagina, making women feel itchy and uncomfortable. Touch the genital area with dirty hands Using dirty hands to clean the “private area” is like inviting bacteria to enter the body. Therefore, whenever cleaning your genitals, it is most important to wash your hands well. In addition, if using loofah in the shower, wash well before using. This step helps to remove dirt, bacteria in the loofah and prevent their invasion inside. Use sanitary napkins daily Using tampons every day too often causes gynecological infections (Artwork) According to the gynecologist, the frequent use of tampons every day will make the secret area more secret and more likely to lead to gynecological infections. Use hair removal cream The borne hair has a certain protective function against mechanical impacts, friction from outside. However, if the genital area is too dense, it will partly affect the aesthetics as well as the excretion of sweat. Therefore, many women choose to remove hair quickly with bleaching cream. Hair removal creams are thought to be harmless but a major cause of vaginal infections (Artwork) The depilatory creams often make the texture of the hair weak and brittle, just after 10 minutes of use and using a soft cloth to wipe the hairs can separate. However, bleaching creams that are not suitable for genital skin can cause allergies and infections that are dangerous for women.

Scientists’ discoveries at the Smithsonian National Museum of Natural History (NMNH) and University of Florida (UF) have shown that marine biodiversity studies can enhance biomedical research. The naming of the compound Gatorbulin-1 (GB1) found in blue algae is a tribute to UF researchers and global partners who lit the torch for the discovery and traits of algae. lam. From self-defense to drugs Cyanobacteria are single-celled terrestrial and aquatic organisms around the world. They can use chemicals to defend themselves against predators. These chemicals also play a role in helping the cyanobacteria communicate. “ We studied a series of compounds called Quorum’s emotional inhibitors that affect the chemical signals that cyanobacteria have, ” said Dr. Valerie Paul, a chemical ecologist at Smithsonian Marine Station. used to communicate. The Quorum emotion is a name for the way bacteria communicate using chemical signals. The scientists examined the cyanobacteria’s communication and defense compounds to test for biomedical properties. Often they realize the compound’s medical potential before understanding why cyanobacteria take it. In a new study, GB1 was shown to have significant anticancer activity with the potential for a new drug formulation. But scientists are not quite sure how cyanobacteria use it. TS. Nature has optimized these compounds, which are created for a certain purpose, in the case of blue-green algae, said Paul, as self-defense. Chemical structure of Gatorbulin-1 (GB1) molecule. From the sea to the lab The blue-green algae targeted, Lyngbya confervoides, was discovered more than a decade before Dr. Paul started collecting this species. She quickly realized that the algae produced many different compounds, so she sent the samples to her collaborator Professor Hendrik Luesch for further study. But finding a new compound like GB1 that has the potential to make a new drug is a long process (not including the time it takes to add and test it to convert the compound into a safe, functional drug). The first stage of the procedure is to isolate and demonstrate that the purified compound can selectively kill cancer cells. Spurred by this discovery, Prof. Hendrik’s team was trying to find a way to synthesize the substance in the laboratory. A reliable way to produce GB1 is the first important thing to do in-depth research. “We like to stay in place to collect more cyanobacteria to isolate enough materials for advanced research,” Dr. Hendrik said. As organic chemists, we are able to replicate these natural molecules in larger quantities in the laboratory without having to depend on cyanobacteria. GB1 has been added to additional stages for the synthesis process. Scientists have discovered that GB1 targets a protein in cells called Tubulin – the same protein cells require during cell division and uses it to build ” internal scaffolding ”. While there are many chemotherapy drugs that target Tubulin, Prof. Hendrik and colleagues assert that GB1 is more special because it interacts with Tubulin in new ways. Now researchers are eager to see GB1 as effective in the real world as well as its potential to make anti-cancer drugs. The cyanobacteria that produced Gatorbulin-1 (GBI) was recognized as the algae Lyngbya confervoides. Healing ability of biochemistry Organic chemists often turn to nature to study drug formulation. For example, compounds in terrestrial life mechanisms such as plants and fungi led to the creation of important drugs such as penicillin that is now a staple of modern medicine. In the ocean, about three-quarters of the earth’s surface has yet to be touched by humans. “It’s really a chemical war in the ocean,” said Professor Hendrik. The more battles and communications like that will help us humans understand more about the active compounds that can apply to mankind. ” And Dr. Paul said: “From a chemical ecologist’s point of view, this biodiversity is equivalent to chemical diversity. We can find everything in the ocean we never dreamed of. ” Nguyen Thanh Hai ( (According to smithsonianmag) )

Mercedes-AMG’s new hybrid supercar has been around since March when the German automaker introduced its Project One hypercar and F1 racing car for the 2021 season. It can be seen that Mercedes is continuing to experiment to perfect the GT 73e. This is confirmed to be the most advanced variant of the next generation Mercedes-AMG GT 4-Door and is expected to be officially launched later this year. The Mercedes-AMG GT 73e is developed on a new hybrid technology platform called E Performance. In addition to the GT 4-Door, the new generation C-Class will also have a high-performance variant combining a gasoline engine and an electric motor.

His rabbit farm started operating from December 2019. Mr. Hai analyzed: Rabbit meat is delicious and nutritious, processed many attractive dishes, is one of the foods that are currently favored by many consumers and the market …

Mr. Hai’s rabbit farm has a regular scale of 6,000 animals and is well-invested. Photo: Nhu Cuong.

His barn is about a few hundred meters from his house, on an area of ​​300 square meters of tender land during a period of 50 years. The cage is built in a closed and sustainable way with the entire iron frame, anti-heat roof, and a bright glass window system.

He designed and built a cage with 6 rows of compartments to separate mother rabbits, meat rabbits, breeding rabbits to suit breeding and care. The barn is fitted with LED lighting system, consumes 1500-2000 kW / month, 3 cooling fans with a capacity of 0.4W – 2.2 kW / month, and security camera system.

Water is taken from the family drilled well to clean the barn, clean filtered water to ensure the rabbits drink every day. To avoid environmental pollution and disease prevention, he uses a bioga gas tank to treat liquid waste, daily solid waste is collected to fertilize plants at home.

As a livestock production facility, so the animal husbandry officer in the village and commune often comes to advise him on how to take care of and clean the environment to prevent epidemics, ensure product safety. rate.

Visitors to Hai’s model of rabbit raising. Photo: Nhu Cuong.

The white rabbit he is raising belongs to a New Zealand hybrid rabbit that is purchased from a reputable breed with quality assurance. Rabbit food is biosafety pellets, ordered from reputable dealers inside and outside the district.

Mr. Hai shared: Time to feed rabbits twice a day in the morning and afternoon, but must be punctual. In addition, feed your rabbits with clean vegetables grown in the garden once a day in the afternoon. The mother rabbit is 28 – 32 days pregnant and needs careful care.

Each year, a mother rabbit breeds 6 litters, each batch from 6-8 children, however, it is necessary to choose 6 healthy animals for commercial farming. Breeding rabbits are produced mainly for breeding the next litter or to be sold to people in need.

To prevent epidemics, Mr. Hai implements a vaccination regime of 4 months, 1 time of vaccination, 1 month of 2 days of medicine to prevent rabbits from scabies and ringworm …

From raising to harvest time is about 4.5 – 5 months, each rabbit individual has an average weight of 2.3 – 2.5 kg / head, parent rabbits are 3.5 – 4 heavier, 0 kg / head; Average selling price is 100 thousand VND / kg, selling 80 thousand VND / kg.

Mr. Hai said that raising rabbits is not too difficult, but requires technical compliance, especially ensuring disease prevention. Photo: NC.

When leaving the barn, “Hai Huyen Phat Rabbit Farm” bustles with buyers and sellers, mainly local people, restaurants, restaurants, traders … If processed, transport the products to the buyers.

Mr. Hai did not hesitate to disclose: The initial investment capital was also quite large, estimated at 1.2 billion VND to build cages, livestock tools, food, preventive medicine, 60 million VND for breeding rabbits … Thanks to the methodical investment and strict technical rearing, if subtracting all the costs, the profit is about 400 million VND / year.

Mr. Hai also said that in the near future, he will build a bioga gas tunnel to treat waste, use accumulated capital plus borrow more credit to expand the rabbit farm area by 200 square meters to continue developing the family economy.

Mr. Andrew Barnes, the Australian Deputy Embassy in Hanoi and the delegation inspected the sea cucumber farming area in Van Ninh district (Khanh Hoa).

Attending the seminar were Mr. Andrew Barnes, Deputy Embassy of Australia in Vietnam; representatives of the Ministry of Agriculture and Rural Development of Vietnam and the agriculture sectors of Khanh Hoa and Quang Ngai provinces.

In Vietnam, the project selected white-breasted sea cucumber (Holothuria fuscogilva) for research, hatchery production and nursery testing. After one year of implementation in Khanh Hoa and Quang Ninh, the results were positive. Evaluation shows that sea cucumber is suitable for natural conditions in Khanh Hoa. Specifically, from the seed with a weight of about 0.3g and then a weight of 60g, the survival rate reached 92%.

Mr. Nguyen Duc Thoai, in Dam Mon village, Van Thanh commune, Van Ninh district (Khanh Hoa) is one of the three households implementing experimental farming, said sea cucumber grows and develops well, high survival rate. Therefore, he wants the project to continue to multiply on a large scale to serve farmers in need.

Dr. Nguyen Dinh Quang Duy, Deputy Director of Central National Center for Seafood Breeding, Research Institute for Aquaculture 3, said that the culture of hormones instead of traditional methods stimulated the reproduction of sea cucumbers. white success. Accordingly, the research team has produced nearly 20,000 breeders for commercial experiments and experimental farming.

“The results of the project initially bring about very positive results when successfully producing sea cucumber, the type of economic value 5 times higher than that of sand sea cucumber; At the same time, opening up opportunities to create livelihoods for farmers in the coming time as well as reducing the pressure on exploiting natural sea cucumbers that are endangered, contributing to environmental protection ”, Dr. Nguyen Dinh Duy product.

Facing the results from the project, Mr. Andrew Barnes, Deputy Embassy of Australia in Vietnam highly appreciated the cooperation between USC University and Research Institute for Aquaculture 3 to successfully produce white-breasted sea cucumber. with new methods, opening up valuable opportunities for the production of sea cucumbers for this industry. When he looked at the sea cucumbers farmed at sea in Van Ninh, he realized that the project goal was very clear, initially creating a new career for farmers, reducing the pressure of sea cucumber exploitation in the wild, contributing to protecting environmental protection and aquatic resource diversity.

Sea cucumbers raised in Dam Mon village, Van Thanh commune, Van Ninh district, Khanh Hoa province grew and developed well.

Representatives of the Department of Agriculture and Rural Development of Quang Ngai expressed interest in the successful application of white breasted sea cucumber varieties. Currently, Quang Ngai does not have any model to raise sea cucumber. Sand sea cucumber has been cultured in the area for about 3 years now with remarkable results. Therefore, the province is oriented to develop sand sea cucumbers on a large scale, have seed stocked in Ly Son marine reserve in 2021 and soon approach research technology to produce white sea cucumber seed.

Regarding the stocking of sea cucumbers at the Ly Son marine reserve, Dr. Truong Ha Phuong, Deputy Director in charge of Research Institute of Aquaculture 3, said that it is expected that in the coming time, it will coordinate to stocking in the area. this field by artificial seed sources.

At the seminar, delegates also focused on discussing the possibility of commercialization and development direction of sea cucumber in Vietnam; in which the issue is of concern is the output of the product.

According to Mr. Le Thanh Nhan, Chairman and General Director of Vietnam Sea cucumber Joint Stock Company, which has a sea cucumber processing factory according to high standards of Japan, the US, is not only dry processing for export. sold crude. Although there are about 90% dry products on the world market, the company will produce products for consumers to use.

Nhan also said that in recent years, the company has boosted the purchase of sandy sea cucumber in Phu Yen and Khanh Hoa. At the same time, confirmed to consume the output of sea cucumbers to ensure farmers because the company only consumes farmed sea cucumbers, not natural sea cucumbers. In the company’s strategy is to spend 90% of products for export and 10% for domestic service because the domestic market is not used to sea cucumber. The company’s products have also been exported and market expansion continues.

Sea cucumbers were cultured for trials in Khanh Hoa.

Prof. Dr. Ngo Xuan Binh, Deputy Director of Department of Science and Technology (Ministry of Science and Technology), said that technology to stimulate reproduction by hormone, Vietnam currently has not applied much. Therefore, with the successful production of white-breasted sea cucumber with this technology, it creates a breakthrough, opens up opportunities as well as creates a livelihood for farmers. However, for this technology to produce sea cucumber more successful, commercialization is needed.

According to Assoc.Prof. Dr. Nguyen Huu Ninh, Deputy Director of Department of Science, Technology and Environment (Ministry of Agriculture and Rural Development), Australia has supported Vietnam a lot in the agricultural sector recently; including seafood. Through cooperation, we grasp new technologies as well as enhance research capacity.

For sea cucumbers, in the past, Vietnam produced sandy sea cucumber by traditional methods such as heat stimulation, so it was not as active as hormone-based fertility stimulation. Mr. Ninh believes that with this technology, other rare and precious sea cucumbers will be successfully produced in the near future. On the other hand, it can reduce illegal exploitation at sea, contribute to overcoming IUU yellow card as well as serving strategic direction of fisheries development.

Initially raised and developed well

On April 14, Research Institute for Aquaculture 3 (Institute III) in collaboration with USC University (Australia) organized a workshop to evaluate the results of the project to improve production of high value sea cucumber through the public. molecular turmeric.

Accordingly, the above project comes from the project idea: Strength of cooperation between USC and Institute III on sea cucumber research.

Workshop scientists evaluate the results of successful production of white breast sea cucumber by molecular technology. Photo: KS.

In Vietnam, the component selected white-breasted sea cucumber (Holothuria fuscogilva) to research on hatchery production and rearing experiment led by Dr. Nguyen Dinh Quang Duy (Institute III).

According to Professor Abigail, USC (Australia), white-breasted sea cucumber is a species of high economic value, and Institute III is a place for reproductive research in sand sea cucumber, so it is very suitable to study white-breasted sea cucumber. have a lot of experience in this field.

Currently, aquaculture in Vietnam needs 20 million sea cucumbers. But currently there are only about 1 million breeds of ginseng. Therefore, the breeding of white-breasted sea cucumber is very necessary to meet the needs of the market, while increasing the economic value of sea cucumber.

With the use of a hormone produced at USC, extracted from the nerves of the sea cucumber itself, and then transplanted to a large-scale multiplication of mem fungi in the laboratory, the hormone has a stimulating effect. Like high reproduction and does not affect the health of the parent sea cucumber.

Dr. Nguyen Dinh Quang Duy confirmed, the use of hormones instead of traditional methods has stimulated the reproduction of white-breasted sea cucumber successfully.

Accordingly, the technology has produced nearly 20,000 breeders for experiments and commercial trials on cages in Khanh Hoa and Quang Ninh with 3 participating households.

Results after 8 months of farming, white breast sea cucumber achieved good results. Specifically, from seed with a weight of about 0.3 grams raised to 60 grams of weight and 92% survival rate.

Regarding the initial results of the experimental release of white-breasted sea cucumbers on cages, Mr. Nguyen Duc Thoai, from Dam Mon village, Van Thanh commune, Van Ninh district (Khanh Hoa) said that sea cucumber grows and develops well, high survival rate. Therefore, he wants the project to continue breeding on a large scale to serve farmers in need.

Dr. Nguyen Dinh Quang Duy shared: Initial project results bring very good results when successfully producing white-breasted sea cucumber, which has an economic value 5 times higher than that of sand sea cucumber. At the same time, opening up opportunities to create livelihoods for farmers in the coming time, as well as reducing the pressure on exploiting natural sea cucumbers that are endangered, contributing to environmental protection …

Mr. Andrew Barnes, Deputy Embassy of Australia in Vietnam highly appreciated the cooperation between USC and Institute III that successfully produced white breast sea cucumber with a new method, opening up valuable opportunities to produce valuable sea cucumber for the industry. this row.

Not only that, when he surveyed the sea cucumbers farmed at sea in Van Ninh, the more clearly he saw that the project goal was very clear, initially creating a new profession for farmers, as well as reducing pressure to exploit sea cucumbers in natural, thereby protecting the environment better.

Reducing pressure on natural exploitation, opening up new economy

At the seminar, representatives of Quang Ngai Department of Agriculture and Rural Development expressed concern about the successful application of white breast sea cucumber varieties.

According to this representative, Quang Ngai does not currently have any model to raise white-breasted sea cucumber. Sand sea cucumbers have been cultured in the area for about 3 years now with good development results and efficiency. Therefore, Quang Ngai province is oriented to develop sand sea cucumber on a large scale.

GS. Dr. Ngo Xuan Binh, Deputy Director of the Department of Science and Technology (Ministry of Science and Technology), said that technology to stimulate reproduction by hormones in Vietnam has not been applied much.

Therefore, with the successful production of white-breasted sea cucumber with this technology is truly breakthrough, opening up opportunities as well as creating a livelihood for growers. However, in order for the production of white-breasted sea cucumber to be more successful, commercialization is needed.

For white-breasted sea cucumber, the locality wants in 2021 to have seed to stock at Ly Son marine reserve and soon access research technology to produce white-breasted sea cucumber varieties.

Regarding the stocking of white-breasted sea cucumbers at Ly Son marine reserve, Dr. Truong Ha Phuong, Deputy Director of Institute III, said that it is expected that in the near future, it will coordinate to stocking in this area with seed sources. artificial.

And Mr. Vo Khac En, Deputy Director of Khanh Hoa Fisheries Department, assessed that with the successful production of white-breasted sea cucumber, it will help diversify aquatic breeds, reduce the pressure of natural exploitation, especially serving. strategic direction for fisheries development in the coming time.

However, Mr. En also wondered that the white-breasted sea cucumber is often distributed at a depth of tens of meters, so the stocking in cages at low depths, is it really effective?

In this regard, Dr. Nguyen Dinh Quang Duy explained: In the past, white-breasted sea cucumber distributed a lot in shallow areas. However, due to the rarity and overexploitation, sea cucumber has more and more depth distribution.

According to Nhan, in recent times, the company has boosted the purchase of sandy sea cucumber in Phu Yen and Khanh Hoa. The company asserts with sea cucumber farmers is enough to spend the product. Because in the company’s strategy is to spend 90% of products for export and 10% for domestic service.

Currently the domestic market is not used to using sea cucumber. In particular, the company only uses farmed sea cucumbers, not processed natural sea cucumbers. However, the company’s products have been exported to Singapore, Hong Kong, and Taiwan and will soon expand markets in the US, China …

Assoc. TS. Nguyen Huu Ninh, Deputy Director of Department of Science, Technology and Environment (Ministry of Agriculture and Rural Development), said that over the past time, Australia has supported Vietnam a lot in the field of agriculture, including fisheries. Through cooperation, the fisheries sector has captured many new science and technology, as well as capacity building and research.

As for sea cucumbers, our country previously produced sand sea cucumbers by traditional methods such as heat stimulation, so they could not be proactive by technology methods to stimulate reproduction by hormones with high confidence rates.

Mr. Ninh believes that with this technology, other rare and precious sea cucumbers will be successfully produced in the near future. At the same time, express your delight that this technology has linked the business. Projects associated with businesses will have great potential for product development.

The role of collagen in the skin

Collagen is a fibrous protein that accounts for about 30% of the protein in the body, accounting for 70% of the skin structure. The collagen fibers are long and thin, intertwined, creating a collagen network. The collagen network is the foundation of the skin. Collagen plays a role in connecting skin cells, stimulating the metabolism of skin cells, creating elasticity, firmness for the skin, and healing wounds. Therefore, collagen is the main ingredient that helps firm, smooth skin, is the deciding factor for the beauty of the skin. In the skin, collagen is most concentrated in the dermis.

As collagen is deficient due to degradation over time, the collagen fibers under the skin degrade in both quantity and quality, and the skin faces an unrestrained decline. Because at this time, the skin’s frame is weakened, the resistance is poor, wrinkles appear, the skin is sagging, the folds and sagging are worse.

Collagen depletion is a natural process in the body. After the age of 25, the amount of collagen in the body is reduced in two trends:

Quantity reduction: Every year, the amount of collagen decreases by 1%. By the age of 30, the amount of collagen is significantly deficient. This causes the amount of collagen to decrease gradually, the collagen network structure becomes loose and weak. The skin begins to show signs old.

Loss of quality: Due to the degeneration of collagen fibers over time: Being stretched, flaky and broken makes the skin no longer able to maintain firmness, elasticity, and smoothness. Skin becomes dull, dry. Collagen reduction in each year is calculated as follows: After age 25: Skin has a shortage of collagen 1.5%; after the age of 30, there is a 15% shortage of collagen; After age 40, there is a lack of 30% of collagen and 45% of the amount of collagen after the age of 50.

Stress, stress reduces the natural collagen production.

What factors reduce collagen?

Age: Typically, collagen production begins to decline by about 1% per year, from the moment you begin your late teenage years. Depending on the person, this phase can start sooner or later.

Damage by UV rays: Many studies show that up to 90% of skin aging is caused by the sun and only 10% due to factors inside the body. The sun’s UV rays can damage the skin, depleting the collagen in the skin. UV exposure can damage collagen through a variety of mechanisms, including damaging the DNA of collagen-producing cells, as well as promoting the production of free radicals that directly affect collagen. collagen in the skin.

Smoking: Smoking cigarettes can cause many negative health effects, including accelerating premature aging. Smoking cigarettes can reduce the amount of oxygen reaching tissues, making them unable to regenerate, becoming damaged and dying. This can lead to premature wrinkle formation.

Inflammatory diet: Inflammation is one of the main “enemies” of tissues in the body, including collagen-derived connective tissue. Inflammatory diet is a diet high in sugar, simple carbohydrates, processed foods … that can stimulate the immune system, promote inflammation in the body. In particular, the high sugar content in the body causes collagen in the skin to harden, break open, weaken the skin, promote premature aging.

Stress, stress, insomnia: Excessive stress can trigger inflammation, reducing the body’s ability to naturally produce collagen. Stress also increases the hormone cortisol, which in turn contributes to reducing collagen production nature.

Genetics: Genetics is an important factor that can determine how much collagen the body breaks down and rebuilds. Therefore, if your grandparents, your parents keep beautiful, youthful skin for a long time, it is very likely that you will also inherit this.

How to supplement collagen? Skin Care

This is considered to be a powerful antioxidant that both removes harmful free radicals, stimulates the body to produce collagen, maintains skin elasticity and prevents skin aging. effective skin. Vitamin C is a key ingredient in the formation of collagen. If the body lacks vitamin C, the amino acids cannot connect to make collagen.

Dark green vegetables help replenish collagen: Dark green vegetables such as spinach, cabbage, asparagus, broccoli … contain many vitamins, minerals and antioxidants that help prevent Harmful free radicals, improve the skin’s resistance and stimulate the body to increase collagen production effectively.

Red fruits and vegetables: These foods are rich in the antioxidant active ingredient lycopene.
