Gladys Athena Sperling
Gladys Athena Sperling (July 25, 1904 – January 17, 2003) was an American bacteriologist and nutrition researcher at Cornell University from the 1930s into the 1970s. Early life and education Sperling was born in Pulaski, New York, the daughter of Andrew J. Sperling and Stella J. Pratt Sperling. She earned a bachelor's degree in chemistry from Oberlin College in 1928, and completed a master's degree in bacteriology at Cornell University in 1936, with a thesis titled "The Rate of Growth and Gas Production by Escherichia-aerobacter Organisms in Media of Different Compositions". Career Sperling worked at Cornell with Clive McCay in nutrition research, from the 1930s into the 1960s. Much of their work involved experimental studies of nutritional interventions on the growth and aging of rats. She spoke to community groups about nutrition, and was active in the American Association of University Women. She retired from the Animal Sciences department at Cornell in 1970. In retirement ...

Phenylalanine
Phenylalanine (symbol Phe or F) is an essential α-amino acid with the chemical formula, formula . It can be viewed as a benzyl group substituent, substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and chemical polarity, nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The chirality (chemistry)#Naming conventions, L-isomer is used to biochemically form proteins coded for by DNA. Phenylalanine is a precursor for tyrosine, the monoamine neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), and the biological pigment melanin. It is Genetic code, encoded by the messenger RNA codons UUU and UUC. Phenylalanine is found naturally in the milk of mammals. It is used in the manufacture of food and drink products and sold as a nutritional supplement as it is a direct precursor to the neuromodulation, neuromodulator phe ...

Golden Hamster
The golden hamster or Syrian hamster (''Mesocricetus auratus'') is a rodent belonging to the hamster subfamily, Cricetinae. Their natural geographical range is in an Arid, arid region of northern Syria and southern Turkey. Their numbers have been declining in the wild due to a Habitat destruction, loss of habitat from agriculture and deliberate elimination by humans. Thus, wild golden hamsters are now considered endangered by the IUCN, International Union for Conservation of Nature. However, captive breeding programs are well established, and captive-bred golden hamsters are often kept as Small pets, small house pets. They are also used as Animal research, scientific research animals. Syrian hamsters are larger than many of the Phodopus, dwarf hamsters kept as pocket pets (up to five times larger), though the wild European hamster exceeds Syrian hamsters in size. Characteristics Adult golden hamsters can reach around long. Females are usually larger than males, with a body ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parabiosis
Parabiosis is a laboratory technique used in physiological research, derived from the Greek word meaning "living beside." The technique involves the surgical joining of two living organisms in such a way that they develop a single, shared physiological system. Through this approach, researchers can study the exchange of blood, hormones, and other substances between the two organisms, allowing for the examination of a wide range of physiological phenomena and interactions. Parabiosis has been employed in various fields of study, including stem cell research, endocrinology, aging research, and immunology. Heterochronic parabiosis involves parabiosis of animals of different ages; this allows researchers to study how circulating blood-borne factors influence aging and tissue regeneration. The method has led to insights into stem cell function, neurogenesis, regeneration (biology), and aging. In contrast, isochronic parabiosis joins two animals of the same age. Parabiotic experim ...

Bronchiectasis
Bronchiectasis is a disease in which there is permanent enlargement of parts of the bronchi, airways of the lung. Symptoms typically include a chronic cough with sputum, mucus production. Other symptoms include shortness of breath, hemoptysis, coughing up blood, and chest pain. Wheezing and nail clubbing may also occur. Those with the disease often get lung infections. Bronchiectasis may result from a number of infection, infectious and acquired causes, including measles, pneumonia, tuberculosis, immune system problems, as well as the genetic disorder cystic fibrosis. Cystic fibrosis eventually results in severe bronchiectasis in nearly all cases. The cause in 10–50% of those without cystic fibrosis is unknown. The mechanism of disease is breakdown of the airways due to an excessive inflammatory response. Involved airways (bronchi) become enlarged and thus less able to clear secretions. These secretions increase the amount of bacteria in the lungs, resulting in airway blockage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
