USEFUL CAROTENOIDS IN SNAIL EGGS(RAHIMA)


Blood parrot is a hybrid fish artificially crossbred in Taiwan as early as the 1980s. Currently, the Blood parrot is one of the most popular and high-value ornamental fish because of its bright body color. However, the fish cannot synthesize their own carotenoid color. As body color is the major factor that affects the market value of ornamental fish, enhancing it by supplementing pigments in diets is necessary. In aquaculture, synthetically manufactured carotenoids are used as pigmentation of fishes.  

Golden apple snail eggs are usually cemented outside water have been said to contain 72 nmol carotenoids per gram. Previous studies have reported that natural or synthetic carotenoids such as astaxanthin can be used as an additive to enhance fish body coloration and antioxidant activity. Furthermore, additions dietary of astaxanthin extracted from golden apple snail eggs has also shown efficiency for improved skin pigmentation in fancy carp ( Cyprinus carpio) Thus, the use of golden apple snail eggs would benefit to aquaculture and agriculture industry

HAZARD VS. RISK-BASED APPROACHES TO PROTECTING HEALTH (ERNEST)

                                               HAZARD VS. RISK-BASED APPROACHES TO PROTECTING                             HEALTH AND ENVIRONMENT FROM PESTICIDES                                                                      April 2021     What’s the difference between a hazard and risk-based approach? These two approaches are often presented as opposing. However, this is a misrepresentation of risk management. ‘Hazard’ is the potential for a chemical (in this case a pesticide) to cause harm to human health or the environment; Risk , on the other hand , is the probability that the harmful outcome happens. Hazard cannot be separated from risk; it is an integral part of it. Pesticide risk management focuses on reducing the probability (and hence frequency), that people or the  environment will be exposed to pesticides. The hazard-based approach to pesticide regulation is founded on the principle that if an active substance possesses certain hazardous character

Locust as a source of food and feed (Rahima)

イメージ
I came across a pack of roasted locusts at the store the other day and decided to check their nutritional value and study a bit more about them. Locusts are a type of insect from the family Acrididae . They are known to swarm in huge numbers and can travel great distances, causing considerable damage to crops. However, in many African, Middle Eastern, and Asian countries, locusts are considered a delicacy and eaten in abundance. Locusts are an excellent source of protein and contain a variety of fatty acids and minerals. Although not considered palatable by most Americans and Europeans, locusts are an important food source in many other countries.   According to the book "Insects" by Steve Parker, species of locusts vary in protein content from about 50 percent of dry weight to almost 60 percent, making them denser in protein than cows . Researchers have also noted that the cholesterol content in locusts is high, about 286 milligrams per 100 grams, which is higher than th

Full vaccination（Sagae）

We some of the lab members had second vaccination at university. It was so hard situation for me because of side effects. I had heard some news that the side effects of the second vaccine are more serious. It was TRUE. The night after the vaccine, started to increase my body temperature. At midnight temperature already reached 38.5 ℃. And also my bone has pain and "Moderna arm". I could only lay on the bed the whole day by agony. My fever continues till next midnight. I thought my fever had gone down, but then I started to have terrible headaches. Again I spent the time on the bed the whole day. Finally, I recovered fully after 60 hours of vaccination. It was the worst experience in 2021 at least. I wish our painfulness contributes to making the situation better. 大学で二回目のワクチン接種を受けました。結論から言うと、副反応が本当きつかったです。二回目は一回目より副反応がきついと聞いていましたが、その通りです。接種日の夜から熱が上がり始めて、夜中には38.5℃に達しました。きつすぎてベッドに横になる事しかできません。全身の関節は痛むし、モデルナアームも発症しています。次の夜中は明朝まで高熱は続きました。熱が下がったと思ったら次はひどい頭痛です。またベットから動けず一日を過ごします。最終的
