Action spectrum of the retinal mechanism mediating nocturnal light-induced suppression of rat pineal gland N-acetyltransferase
(Elsevier, 1987-03-17)
The spectral properties of the retinal mechanism mediating the inhibitory effects of nocturnal light on pineal gland N-acetyltransferase (NAT) activity were determined. Pineal gland NAT activity declined linearly in albino ...
Binding of carbon tetrachloride metabolites to rat hepatic mitochondrial DNA
(Elsevier, 1984-08)
Radioactivity from [14C]CCl4 was bound to highly purified mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) prepared from livers of rats after a single dose of [14C]CCl4. At a low, non-necrotizing dose as well as at an ...
A sensitive coupled HPLC/RIA technique for separation of endorphins: Multiple forms of B-endorphin in rat pituitary intermediate vs. anterior lobe
(Elsevier, 1981-08)
A technique is described which couples High Performance Liquid Chromatography (HPLC) to radioimmuno assays (RIA), thus achieving high sensitivity with good specificity. This method allows the separation and detection of ...
Rotavirus and reovirus stability in microorganism-free distilled and wastewaters
(Elsevier, 1983)
Survival of calf rotavirus and reovirus under controlled laboratory conditions in microorganism-free, distilled and wastewater at 8 and 26[deg]C was examined by periodic measurement of cytopathic effects (CPE) and indirect ...
Collateral sprouting of nociceptive C-fibers after cut or capsaicin treatment of the sciatic nerve in adult rats
(Elsevier, 1988-08-01)
The innervation area of nociceptive C-fibers in the saphenous nerve of adult rats was detected by the Evans blue technique, in which antidromic excitation of the nociceptive C-fibers causes a visible extravasation of dye ...
A method to reduce interference by sucrose in the detection of thiobarbituric acid-reactive substances
(Elsevier, 1984-03)
A thiobarbituric acid (TBA) reaction for measuring lipid peroxidation products was evaluated for interference by several ingredients commonly used in solutions to prepare or analyze tissue homogenates or subcellular ...
Fecal coliform disappearance in a river impoundment
(Elsevier, 1983)
Fecal coliform (FC) disappearance studies were conducted in Ford Lake during the summer of 1979. Ford Lake, an artificial impoundment at the lower end of the Huron River drainage basin below Ypsilanti, Michigan, receives ...
Stabilization of tetramethylbenzidine (TMB) reaction product at the electron microscopic level by ammonium molybdate
(Elsevier, 1988-10)
The ability to use the tetramethylbenzidine (TMB) method for studying neuronal connections at the electron microscopic level is often difficult because the conditions of osmification and dehydration used in processing the ...
Inhibition of polyphosphoinositide phosphodiesterase by aminoglycoside antibiotics
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-08)
The calcium-activated phosphodiesteratic hydrolysis of 32 P-labeled phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 4-phosphate in prelabeled nerve ending membranes is inhibited by the aminoglycosides neomycin ...
Phase relations between carotid pressure and ongoing electrocortical activity
(Elsevier, 1983-08)
The behavioral significance of changes in the cardiovascular system has been a major source of controversy in psychophysiology. In view of this, it is surprising that so few studies have examined the relationship between ...
