Lacticaseibacillus Casei
''Lacticaseibacillus casei'' is an organism that belongs to the largest genus in the family ''Lactobacillaceae'', a lactic acid bacteria (LAB), that was previously classified as ''Lactobacillus casei''. This bacteria has been identified as facultatively anaerobic or microaerophilic, acid-tolerant, non-spore-forming bacteria. This species is a non-sporing, rod-shaped, gram positive microorganism that can be found within the reproductive and digestive tract of the human body. Since ''L. casei'' can survive in a variety of environmental habitats, it has and continues to be extensively studied by health scientists. Commercially, ''L. casei'' is used in fermenting dairy products and its application as a probiotic. In bacteraemia, it is regarded to be similar in pathogenicity to Lactobacillus and associated with infective endocarditis. Taxonomy The taxonomy of the ''L. casei'' group has been debated for several years because researchers struggled to differentiate between the strain ...

Dairy
A dairy is a place where milk is stored and where butter, cheese, and other dairy products are made, or a place where those products are sold. It may be a room, a building, or a larger establishment. In the United States, the word may also describe a dairy farm or the part of a mixed farm dedicated to milk for human consumption, whether from cows, buffaloes, goats, yaks, sheep, horses or camels. The attributive ''dairy'' describes milk-based products, derivatives, and processes, and the animals and workers involved in their production, for example dairyman, dairymaid, dairy cattle or dairy goat. A dairy farm produces milk and a dairy factory processes it into a variety of dairy products. These establishments constitute the global dairy industry, part of the food industry. The word ''dairy'' comes from an Old English word for ''female servant'', as milking was historically done by dairymaids. Terminology Terminology differs between countries. In the United States, for ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azo Compound
Azo compounds are organic compounds bearing the functional group diazenyl (, in which R and R′ can be either aryl or alkyl groups). IUPAC defines azo compounds as: "Derivatives of diazene (diimide), , wherein both hydrogens are substituted by hydrocarbyl groups, e.g. azobenzene or diphenyldiazene.", where Ph stands for phenyl group. The more stable derivatives contain two aryl groups. The group is called an ''azo group'' (, ). Many textile and leather articles are dyed with azo dyes and pigments. Aryl azo compounds urinary tract infections">Phenazopyridine, an aryl azo compound, is used to treat urinary tract infections">150px Aryl azo compounds are usually stable, crystalline species. Azobenzene is the prototypical aromatic azo compound. It exists mainly as the Cis-trans isomerism, ''trans'' isomer, but upon illumination, converts to the Cis-trans isomerism, ''cis'' isomer. Aromatic azo compounds can be synthesized by azo coupling, which entails an electrophilic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional Food
A functional food is a food claimed to have an additional benefit beyond just nutrition (often one related to health promotion or disease prevention) by modifying the horticulture, cultivation of the native food or by food additive, adding ingredients during manufacturing. The term applies to traits purposely plant breeding, bred into existing edible plants, such as purple or gold potatoes having increased anthocyanin or carotenoid contents, respectively. Functional food manufacturing has the intent "to have physiological benefits and/or reduce the risk of chronic disease beyond basic nutritional functions, and may be similar in appearance to conventional food and consumed as part of a regular diet". The term also applies to food processing practices which include ingredients purposely added with the intent to improve the food health value and for marketing to specific consumer groups. The term was first used in the 1980s in Japan, where a government approval process for func ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakult
is a Japanese sweetened probiotic milk beverage fermented with the bacteria strain '' Lacticaseibacillus casei'' Shirota. It is sold by Yakult Honsha based in Tokyo. The name "Yakult" was coined from ''jahurto'', an Esperanto word meaning "yogurt". Ingredients Yakult's ingredients are water, skimmed milk, glucose-fructose syrup, sucrose, natural flavours (citrus), and live ''Lacticaseibacillus casei'' Shirota bacteria. The strain was originally classified as being ''Lactobacillus casei''. Yakult is prepared by adding glucose to skimmed milk and heating the mixture at 90 to 95 °C for about 30 minutes. After letting it cool down to 45 °C, the mixture is inoculated with the lactobacillus and incubated for 6 to 7 days at 37 to 38 °C. After fermentation, water, sugar, gums, and lactic acid are added. Health claims In 2006, a panel appointed by the Netherlands Nutrition Center (''Voedingscentrum'') to evaluate a marketing request by Yakult found sufficient ...

Actimel
Actimel (known as DanActive in the United States and Canada) is a probiotic yogurt-type drink produced by the French company Danone. Actimel earned over €1.4 billion (US$1.8 billion) in retail sales in 2006. History Actimel was invented in the 1980s when the first steps to developing a fermented milk based on Lactobacillus casei were already taken. It wasn’t until 1994 when it was commercially-launched in Belgium. The word Actimel was derived from the Dutch “Actieve melk” which translates simply as Active Milk. Scientific basis Claimed benefits range from reducing the incidence of diarrhea and rhinitis reduction for young children, to improvement of the immune function in adults and seniors and reduction of duration of winter infections for elderly. A 2007 study published by the ''British Medical Journal'' suggests that the product could help avoid antibiotic-associated diarrhoea and limit ''Clostridioides difficile infections'' in elderly patients.

Fermentation In Food Processing
In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—without an oxidizing agent being used in the reaction. Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy. The term "fermentation" sometimes refers specifically to the chemical conversion of sugars into ethanol, producing alcoholic drinks such as wine, beer, and cider. However, similar processes take place in the leavening of bread (CO2 produced by yeast activity), and in the preservation of sour foods with the production of lactic acid, such as in sauerkraut and yogurt. Humans have an enzyme that gives us an enhanced ability to break down ethanol. Other widely consumed fermented foods include vinegar, olives, and cheese. More localized foods prepared by fermentation may also be based on beans, grain, vegetables, fruit, honey, dairy products, and fish. ...

Clostridioides Difficile Infection
''Clostridioides difficile'' infection (CDI or C-diff), also known as ''Clostridium difficile'' infection, is a symptomatic infection due to the bacterial spores, spore-forming bacterium ''Clostridioides difficile''. Symptoms include watery diarrhea, fever, nausea, and abdominal pain. It makes up about 20% of cases of antibiotic-associated diarrhea. Antibiotics can contribute to detrimental changes in gut microbiota; specifically, they decrease short-chain fatty acid absorption, which results in osmotic, or watery, diarrhea. Complications may include colitis#Infectious, pseudomembranous colitis, toxic megacolon, perforation of the colon, and sepsis. ''Clostridioides difficile'' infection is spread by bacterial spores found within feces. Surfaces may become contaminated with the spores, with further spread occurring via the hands of healthcare workers. Risk factors for infection include antibiotic or proton pump inhibitor use, hospitalization, hypoalbuminemia, other health pro ...

Antibiotic-associated Diarrhea
Antibiotic-associated diarrhea (AAD) results from an imbalance in the colonic microbiota caused by antibiotics. Microbiotal alteration changes carbohydrate metabolism with decreased short-chain fatty acid absorption and an osmotic diarrhea as a result. Another consequence of antibiotic therapy leading to diarrhea is an overgrowth of potentially pathogenic organisms such as ''Clostridioides difficile''. It is defined as frequent loose and watery stools with no other complications. __TOC__ Cause ''Clostridioides difficile'', also known more commonly as ''C. diff'', accounts for 10 to 20% of antibiotic-associated diarrhea cases, because the antibiotics administered for the treatment of certain disease processes such as inflammatory colitis also inadvertently kill a large portion of the gut flora, the normal flora that is usually present within the bowel. With this lower level of "healthy" bacteria present, the overgrowth of ''C. diff'' is then responsible "for elaborating the en ...

Helicobacter Pylori
''Helicobacter pylori'', previously known as ''Campylobacter pylori'', is a gram-negative, Flagellum#bacterial, flagellated, Bacterial cellular morphologies#Helical, helical bacterium. Mutants can have a rod or curved rod shape that exhibits less virulence. Its Helix, helical body (from which the genus name ''Helicobacter'' derives) is thought to have evolved to penetrate the gastric mucosa, mucous lining of the stomach, helped by its flagella, and thereby establish infection. While many earlier reports of an association between bacteria and the ulcers had existed, such as the works of John Lykoudis, it was only in 1983 when the bacterium was formally described for the first time in the English-language Western literature as the causal agent of peptic ulcer, gastric ulcers by Australian physician-scientists Barry Marshall and Robin Warren. In 2005, the pair was awarded the Nobel Prize in Physiology or Medicine for their discovery. Infection of the stomach with ''H. pylori'' doe ...

In Vivo
Studies that are ''in vivo'' (Latin for "within the living"; often not italicized in English) are those in which the effects of various biological entities are tested on whole, living organisms or cells, usually animals, including humans, and plants, as opposed to a tissue extract or dead organism. Examples of investigations ''in vivo'' include: the pathogenesis of disease by comparing the effects of bacterial infection with the effects of purified bacterial toxins; the development of non-antibiotics, antiviral drugs, and new drugs generally; and new surgical procedures. Consequently, animal testing and clinical trials are major elements of ''in vivo'' research. ''In vivo'' testing is often employed over ''in vitro'' because it is better suited for observing the overall effects of an experiment on a living subject. In drug discovery, for example, verification of efficacy ''in vivo'' is crucial, because ''in vitro'' assays can sometimes yield misleading results with drug c ...
