na+ modulates the k+ permeability and the membrane potential of alkalophilic bacillus.in the absence of na+ in the medium, the membrane potential of obligately alkalophilic bacillus cells was found to be decreased by the addition of k+ to the medium, whereas k+ addition in the presence of na+ had no effect. rb+ showed essentially the same effect as k+. the decreased membrane potential was quickly restored by lowering the k+ concentration in the medium or by adding na+ or li+ to the medium. thus, in the absence of na+, the membrane potential of alkalophilic bacillus seems to be af ...19873663674
liposome as an adjuvant for the production of estradiol antibodies.mice immunized with liposome associated estradiol-bovine serum albumin conjugate (e2-bsa) showed a significantly higher estradiol-specific immune response than did mice injected with the free conjugate. the conjugation of estradiol with bsa is imperative, since injection of liposomes with estradiol in the lipid bilayer was found to be ineffective in inducing an immune response. entrapment of e2-bsa in neutral and positively charged liposomes was found to be a potent mode of immunostimulation, ev ...19873666803

acute diarrhoea in adults: a prospective study.a prospective study of 74 adults with acute diarrhoea was carried out in sydney in 1984-1985 to determine the infective agents that were involved and their relationship to clinical, epidemiological and laboratory features. thirty-four potential pathogens were identified in 32 (43.2%) patients. these included, in order of frequency: campylobacter spp., rotavirus, clostridium difficile, salmonella enteritidis, aeromonas hydrophila, vibrio parahaemolyticus, adenovirus, a small round virus and giard ...19873683260
age-dependent activation of glucocorticoid receptors in the cerebral hemispheres of male rats.the binding of [3h]dexamethasone-receptor complexes to purified nuclei was studied in the cerebral hemispheres of immature (3-week-old) and mature (26-week-old) long-evans male rats to determine the age-related changes, if any, in the physicochemical properties of glucocorticoid receptors. our data show that heat activation (for 45 min at 25 degrees c) significantly enhances the nuclear binding of [3h]dexamethasone-receptor complexes in rats of both ages, with a greater magnitude in immature rat ...19873690338

colocalization of microtubule-associated protein 1a and microtubule-associated protein 2 on neuronal microtubules in situ revealed with double-label immunoelectron microscopy.microtubule-associated protein 1a (map1a) and microtubule-associated protein 2 (map2) were shown to be colocalized on the same microtubules (mts) within neuronal cytoskeletons by double-label immunoelectron microscopy. to investigate the electron microscopic disposition of map1a and map2 and their relationship to mts in vivo, and to determine whether there are different subsets of mts which specifically bind either map1 or map2, we employed a double-label immunogold procedure on rat cerebella us ...19873294858
x-linked gene expression and x-chromosome inactivation: marsupials, mouse, and man compared.the existence of paternal x inactivation in australian and american marsupial species suggests that this feature of x-chromosome dosage compensation is not a recent adaptation, but probably predates the evolutionary separation of the australian and american marsupial lineages. although it is theoretically possible that the marsupial system is one of random x inactivation with p greater than 0.99 and q less than 0.01 and dependent on parental source, no instance of random x inactivation (p = q or ...19873298156
comparison between proteinases of human seminal plasma and of sperm origin.a comparison of the alkaline proteinase activity of human seminal plasma, the seminal non-gamete cellular material and spermatozoa was made by gelatin-sodium dodecyl sulfate-polyacrylamide gel electrophoresis (gelatin-sds-page) zymography. several major (molecular weights = greater than 56,000) and minor (35,000 to 44,000) bands of proteinase activity were seen in the seminal plasma samples from nonvasectomized and vasectomized, healthy donors. similar activity profiles were observed in the nong ...19873305451
