(1980)We measured the methylation of ribosomal proteins from the 30S and 50S subunits of Bacillus subtilis after growing the cells in the presence of [1-14C]methionine and [methyl-3H]methionine. Two-dimensional polyacrylamide ...
-
(1980)The acute adrenal response to potassium chloride and angiotensin II (A II) infusions was studied in hypopituitary patients and compared with normal subjects. The peripheral plasma levels of aldosterone (PAC), cortisol (F), ...
-
(1980)It is suggested in this paper that alexithymia may be a graded behavioral characteristic in much the same way as psychological dimensions are. Under this assumption every person would possess an alexithymic score, however ...

-
(1980)Cell membrane regions characterized by alkaline phosphatase activity are described in cleaving mouse embryos and early blastocysts. Enzyme activity is demonstrated by light and electron microscopy, from the late 4-cell ...
-
(1980)Hormonal substances for male fertility regulation administered orally or by injection are currently undergoing clinical evaluation. These trials, sponsored by the World Health Organization, provide unique opportunities ...
-
(1980)Bell's phenomenon (upward and outward rolling of the eyeballs on forcible closure of the eyelids) was studied in normal adults and in patients suffering from Parkinson's disease. Advancing age correlates with diminution ...
-
(Informa Healthcare, 1980)1. In rat liver mitochondria, 6-chloro-1,2,3-benzothiadiazole inhibited ADP phosphorylation and Ca2+-transport when the energy required for these processes came from the oxidation of NAD-linked substrates. The inhibition ...
-
(1980)The changes occurring in the electrophoretic pattern of the cerebrospinal fluid (CSF) proteins in 37 children with nontumoral hydrocephalus, and the protein pattern of 12 children without organic neurological disease, were ...
-
(1980)We obtained specimens from the angle of the eye during a trabeculotomy-trabeculectomy operation of a 5-month-old boy with congenital glaucoma. Light and electron microscopy of the anterior chamber angle showed the presence ...
-
(1976)The authors suggest that a qualitative change in lecithin is responsible for the decrease in surface activity of dogs subjected to hemorrhagic shock. Phospholipid containing unsaturated fatty acids form an expanded film ...
-
(1980)Pharmacokinetic parameters of amoxicillin were studied in healthy fasted subjects after both oral and intravenous administration of a single 50 mg dose. Serum levels and urinary excretion rates were determined at various ...
-
Unconjugated steroids in the fallopian tube and peripheral blood during the normal menstrual cycle (1980)Daily plasma samples were obtained from 22 high-parity normal women beginning on day 9 of the menstrual cycle. At varying times in the cycle, salpingectomy was performed and the excised tube was divided into isthmic, ...
-
(1979)Penetration menschlicher Spermatozoen in Zona pellucida‐freie Hamster‐Oozyten. Test zur überprüfung der Fertilisation von Spermatozoen Der Eintritt menschlicher Spermatozoen in pellucidafreie Oozyten von Hamstern wurde ...
-
(1976)Using the microinjection technique it has been possible to measure the hydrolysis of (H3) cAMP injected into Xenopus laevis oocytes. A very active cAMP phosphosidiesterase activity hydrolyzes its substrate to 5'AMP at a ...
-
(1980)The effects of low concentrations of 4-aminopyridine (4-AP) were studied on the frog sinus venosus by means of intracellular microelectrodes. 4-AP depressed spontaneous automaticity. This effect was not reversed by atropine. ...
-
(1979)Studies of lung function in high altitude populations have suggested the influence of hypoxic environment on the development of this characteristic independent of confounding variables such as ethnicity and habitual exercise. ...
