(1997)The hepatotoxic effect of a dried root extract of Aralia mandshurica over a period of 60 days (0.16 g/kg, 1.5 g/kg and 3 g/kg) was studied in Landrace pigs of both sexes. The toxic effect of Aralia mandshurica was evaluated ...
-
(1997)Necturus gallbladder epithelial cells bathed in 10 mM HCO3/1% CO2 display sizable basolateral membrane conductances for Cl- (G(Cl)/b) and K+ (G(K)/b). Lowering the osmolality of the apical bathing solution hyperpolarized ...
-
(1997)A new strategy and four new methods are presented to calculate the limits of the confident interval for an estimate of a proportion equal to 1.0 or 0.0. A current formula which includes 1/(2n) for continuity correction ...
-
(Biophysical Society, 1997)Recent studies have revealed that binding of annexin I to phospholipids induces the formation of a second phospholipid binding site. It is shown that the N terminus on the concave side of membrane-bound annexin I is cleaved ...
-
(1997)This study was undertaken to investigate the mechanisms that determine abnormal gas exchange during acute exacerbations of chronic obstructive pulmonary disease (COPD). Thirteen COPD patients, hospitalized because of an ...
-
(1997)Rats genetically selected for their different ethanol voluntary consumption, UChA (low consumer) and UChB (high consumer) were used. Naive UChA and UChB rats or submitted to ethanol chronic exposure, received an IP dose ...
-
(1997)Parameters related to hepatic oxidative stress, cell injury, and liver histology were determined in control rats and in animals treated with 3,3',5- triiodothyronine (T3), after in vitro perfusion under normoxic or ischemia- ...

(Entomological Society of America, 1996)The life cycle of apterous and alate viviparae of pink and green color forms of the English grain aphid, Sitobion avenae (F.), were compared at 20 ± 1°C and a photoperiod of 14:10 (L:D) h, using individually caged aphids ...
-
(1997)Background. Protective immunity against rotavirus infection is directed against antigenic epitopes on the outer capsid proteins VP7 and VP4. Our aim was to characterize the epidemiology of rotavirus antigenic types over ...
-
(1997)Altered small intestinal motility has been observed in patients with liver cirrhosis. Its pathophysiology remains to be defined. Our aim was to investigate the effect of orthotopic liver transplantation on small intestinal ...
-
(Biophysical Society, 1997)Inositol 1,4,5-trisphosphate (InsP3) binds to its receptor channels and causes liberation of Ca2+ from intracellular stores, frequently in an oscillatory manner. In addition to InsP3, the activation and inactivation ...
-
(Society for the Study of Amphibians and Reptiles, 1997)The leptodactylid frogs Batrachyla taeniata, B. antartandica and B. leptopus in southern Chile produce advertisement calls composed of short pulses, repeated in species-specific patterns. Batrachyla leptopus has a call ...
-
(American Society of Tropical Medicine and Hygiene, 1997)During an investigation of hantavirus pulmonary syndrome (HPS) in Paraguay in 1995, sera from persons with HPS-like illness, houshold contacts of confirmed HPS case-patients, and a sample of the area residents were analyzed ...
-
(Biophysical Society, 1997)We have previously shown that the 40-residue peptide termed amyloid β- protein (AβP[1-40]) in solution forms cation-selective channels across artificial phospholipid bilayer membranes. To determine whether AβP[1-40] also ...
-
(Elsevier Ireland Ltd, 1997)Postsynaptic densities (PSDs) were isolated from rat brain cortex and hippocampus, purified and incorporated into giant (5-80 μm in diameter) liposomes. Gigaohm seals were obtained with a patch-clamp pipette, and a giant ...
