Organoleptic tests are sometimes conducted to determine if food or pharmaceutical products can transfer tastes or odors to the materials and components they are packaged in. Shelf-life studies often use taste, sight, and smell (in addition to food chemistry and toxicology tests) to determine whether a food product is safe to consume.
Food poisoning symptoms can vary widely in severity, as can the length of time one feels sick. Many people feel better after several hours, but it is not uncommon for symptoms to persist for 24 to ...
Orexin (/ ɒ ˈ r ɛ k s ɪ n /), also known as hypocretin, is a neuropeptide that regulates arousal, wakefulness, and appetite. [5] It exists in the forms of orexin-A and orexin-B.The most common form of narcolepsy, type 1, in which the individual experiences brief losses of muscle tone ("drop attacks" or cataplexy), is caused by a lack of orexin in the brain due to destruction of the cells ...
Foodborne illness (also known as foodborne disease and food poisoning) [1] is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, [2] as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.
The Center for Science in the Public Interest has compiled a list of risky FDA-regulated food and a field guide to meat and poultry safety. Check out the slideshow above to discover which foods ...
Environmentally sustainable practices, animal welfare, and authenticity play a subjective role when considering the quality of food. [1]Many consumers also rely on manufacturing and processing standards, particularly to know what ingredients are present, due to dietary, nutritional requirements (kosher, halal, vegetarian), or medical conditions (e.g., diabetes, or allergies).
Both orexin receptors exhibit a similar pharmacology – the 2 orexin peptides, orexin-A and orexin-B, bind to both receptors and, in each case, agonist binding results in an increase in intracellular calcium levels. However, orexin-B shows a 5- to 10-fold selectivity for orexin receptor type 2, whilst orexin-A is equipotent at both receptors ...
An orexin receptor antagonist, or orexin antagonist, is a drug that inhibits the effect of orexin by acting as a receptor antagonist of one (selective orexin receptor antagonist or SORA) or both (dual orexin receptor antagonis or DORA) of the orexin receptors, OX 1 and OX 2. [1] Medical applications include treatment of sleep disorders such as ...
