Neurochemical Effects of Concurrent Exposure to Repeated Stress and Chlorpyrifos on the Central Nervous System
… enzymes, and maximum binding density (Bmax) and equilibrium dissociation rate constant (Kd) of NMDA and total muscarinic receptors were studied in Long-Evans rats. The study was divided into 4 experiments. The first experiment was to find the dose of CPF to use for studies on the …

THE CHARACTERIZATION AND REGULATION OF BENZODIAZEPINE BINDING SITES IN THE MAMMALIAN RETINA, CEREBRAL CORTEX AND KIDNEY
… there was a rapid increase in receptor density (Bmax) during the first 2 weeks of neonatal life. This increase could be described by the function, a·eᵏˣ, where a = 1.8 pmol/brain, k = 0.23 weeks⁻¹ and x = time in weeks (r = 0.98). By 3-4 weeks of age, adult levels of [³H]FLU binding were reached …

Effect of Long-Term Hypoxia on Myocardial Alpha1- Receptors
… α<sub>1</sub>-adrenergic receptor density (Bmax) declined during developmental process with both fetal left ventricle(LV) and fetal right ventricle(RV) having significantly more binding sites than respective adult ventricles. We also demonstrated that the positive inotropic response to the …

Μελέτη των θέσεων δέσμευσης του L-γλουταμικού οξέος σε φυσιολογική και ατροφική ανθρώπινη παρεγκεφαλίδα: Συμβολή στη μελέτη της ελαιογεφυρο-παρεγκεφαλιδικής ατροφίας
… were observed with age, whereas the highest Bmax value was observed at the age of 1 year. Autoradiography revealed L-glutamate binding sites in both granule cell and molecular layers of human cerebellum. In the presense of Cl⁻ ions an increase of about 2,5 times was observed in the molecular …

PLASTIC CHANGES IN THE INHIBITORY GLYCINE SYSTEM OF THE DORSAL COCHLEAR NUCLEUS (DCN) IN A RAT MODEL OF TINNITUS
… significant age-related down-regulation of GlyR (Bmax). Tinnitus-related changes in GlyR &alpha<sub>1</sub> protein level was reflected in the decline of the GlyR (Bmax) in young exposed rats and up-regulated GlyRs in aged exposed animals. The GlyRs in DCN of young exposed animals also …

Investigating Exoplanets and Transients Using Small-Aperture Telescopes
… as an example. A peak B apparent magnitude, Bmax of 11.80 +/- 0.14 mag is observed at a tmax of 56690.79 +/- 0.01 MJD and provides Dm15 = 0.98 +/- 0.20 mag. A peak E(B-V) extinction of 1.24 +/- 0.16 mag (E(B-V)host = 1.19 +/- 0.16 mag) is determined.

The Na/K-ATPase in the gills of Antarctic and New Zealand nototheniids: The Physiologic and Molecular Effects of Warm-acclimation.
… Using [3H]-ouabain binding techniques, the Bmax and K(| values of gill Na/K-ATPase enzymes were determined. No difference in the Bmax or Kd of the warm-acclimated T. bernacchii accounted for the increase in Na/K-ATPase activity. The change in gill Na/K-ATPase activity in the warm-acclimated …

Characterization of the Beta-2 Adrenergic Receptor Mechanism in Bovine Neutrophils, and Some Effects of Inflammatory Stimuli on its Function
… we observed a maximum specific binding density (Bmax) value of 0.19 fmol per 100,000 bovine neutrophils. Although this value is approximately equal to what we observed with dairy cow neutrophils, human neutrophil Bmax values with this radioligand are anywhere from five to ten-fold greater, which …
