Koller named this hormone contractin (1580-1582, 2186-2188). Sensitivity of bacteria to the action of penicillin.
They defined eukaryotes as cells containing membrane-bound structures called organelles, the most important of which was the nucleus. du Vigneaud V, Cohn M, Chandler JP, Schenck JR, Simmonds S. The utilization of the methyl group of methionine in the biological synthesis of choline and creatine.
By this definition, all cells of multi-cellular plants and animals were eukaryotes. The Journal of Biological Chemistry 140: 625-41 808.
They artificially blocked tubular metabolic activity with hydrocyanic acid, collected ureter filtrate, and found that water, chloride, bicarbonate, and glucose are normally reabsorbed from the glomerular filtrate by the tubular cells. In sequential studies, their Hib-tetanus conjugate elicited protective levels in mice, rabbits, young rhesus monkeys, and then in human adults, children, and infants. Proceedings of the National Academy of Sciences of the United States of America 44: 648-61 797.
They also found that pituitrin (a proprietary preparation of the posterior lobe of the pituitary gland) influenced the re-absorption mechanisms for water and chloride and that without it the mammalian kidney reverted to a urine characteristic of fish and amphibian classes (2749). Mangelsdorf (US), using Nicotiana tabacum as their research material, laid the foundation for understanding gametophytic self-incompatibility (833). Their achievement opened the door to their and others' development of conjugate vaccines for other bacterial pathogens whose surface polysaccharide could serve as a protective antigen (2391, 2519, 2520). Boeck (US) and Jaroslav Drbohlav (US) were the first to develop in vitro cultures of Endamoeba histolytica. Clinical evaluation studies in lepromatous leprosy: First series: Diasone (Diamidin), 4-4' diaminodiphenyl sulfone, dihydrostreptomycin.

Richard Adolf Zsigmondy (AT-DE) received the Nobel Prize in Chemistry for his demonstration of the heterogeneous nature of colloid solutions and for the methods he used, which have since become fundamental in modern colloid chemistry.
Pro means before and eu means true, karyote refers to a nut or kernel (483, 484).“Protozoologists agree today in considering the flagellated autotrophs the most primitive of the Protozoa possessing a true nucleus, Eukaryotes (a group which also includes the plants and the Metazoans), because they alone have the power to completely synthesize their protoplasm from a mineral milieu. Decomposition of the capsular polysaccharide of pneumonococcus type III by a bacterial enzyme. The production of bactericidal substances by aerobic sporulating bacilli. Gonadotropin release in relation to electrical activity in hypothalamic neurons.
Heterotrophic organisms are therefore dependent on them for their existence as well as on chemotrophic Prokaryotes and autotrophs (nitrifying and sulphurous bacteria, Cyanophyceae.” This is a translation by Jan Sapp (CA) from the 1938 reference (2490).
