Light (LM), transmission (TEM) and scanning (SEM) electron microscopic techniques were used to characterize morphologic changes induced in the gallbladder of Syrian hamsters following a one-month estradiol (E) and estradiol + medroxyprogesterone…
Clinicians should be aware of the complications of rhabdomyolysis in patients who ingest doxylamine succinate and other over-the-counter antihistamines. The easy availability of these substances increases the potential not only for intentional…
Methylamine-modified alpha-2-macroglobulin (MA-alpha 2M) has been recently shown to inhibit the biological activity of beta-nerve growth factor (NGF) in promoting neurite outgrowth by embryonic dorsal root ganglia in culture (Koo PH, Liebl DJ, J…
Although sarcoidosis has clinical and histopathologic similarities to some forms of tuberculosis and other mycobacterial infections, attempts to establish a mycobacterial etiology have not been successful. Using cytoplasmic antigens derived from a…
Sexual behavior, knowledge of HIV transmission and prevention, perceived risk of AIDS, and safer sex behavior were studied in a sample of 289 single, pregnant. inner-city women. African-American and European-American women were equally represented.…
In this report the role of olfactory bulb (OB) norepinephrine (NE) in the identification and recognition of urinary chemical cues was examined. In Experiment 1, sexually naive adult male Sprague-Dawley rats were treated with either the noradrenergic…
1. Activation of GABAA receptors can produce both hyperpolarizing and depolarizing responses in CA1 pyramidal cells. The hyperpolarizing response is mediated by a Cl- conductance, but the ionic basis of the depolarizing response is not clear. We…
1. Activation of GABA(A) receptors can produce both hyperpolarizing and depolarizing responses in CA1 pyramidal cells. The hyperpolarizing response is mediated by a Cl- conductance, but the ionic basis of the depolarizing response is not clear. We…
In rat thoracic aorta, contractile responses to arginine vasopressin (AVP) are twofold higher in females than in males. To determine the role of the endothelium in this phenomenon, the effects of endothelium removal and inhibition of nitric oxide…
Conditioning stimulation of afferent fibers in hippocampal area CA1 produced heterosynaptic, posttetanic depression (PTD) of responses evoked by stimulation of an independent set of afferent fibers. PTD was present within 5 s of conditioning…
Ischemic nephropathy (IN) is defined as a clinically significant reduction in glomerular filtration rate in patients with hemodynamically significant obstruction to renal artery flow in a solitary functioning kidney or with bilateral renal artery…
Despite the long history of descriptions of reflex sympathetic dystrophy (RSD), much confusion remains regarding its pathogenesis, diagnosis, and treatment. It most commonly occurs after trauma and is more frequent in women, white persons, and the…
BACKGROUND: Research on the diagnosis and management of obesity in primary care is limited. Our study goals were to describe the rate of obesity in a primary care setting, to identify factors associated with clinically recognized obesity, and to…
Conditioning stimulation applied to afferent fibers in stratum radiatum or stratum oriens of hippocampal area CA1 produced heterosynaptic, posttetanic depression (PTD) of excitatory postsynaptic potentials (EPSPs). PTD amounted to a
CLINICAL CHARACTERISTICS: POLG-related disorders comprise a continuum of overlapping phenotypes that were clinically defined long before their molecular basis was known. Most affected individuals have some, but not all, of the features of a given…
Study objective: To review the clinical and laboratory findings in a large number of patients with pneumococcal bacteremia in the 1980s and identify risk factors associated with increased mortality. Design: Retrospective review of medical records…
A fold that occurs within a joint is referred to as a plica synovialis. Three such plicae are seen with regularity within the human knee joint. These folds are normal structures that represent remnants of mesenchymal tissue and/or septa formed during…
1. The objective of Exp. 1 was to determine whether intracerebroventricular (ICV) injection of cathinone CATH (8.0-32 micrograms) would produce a dose-dependent conditioned place preference (CPP) and/or activation in rats. Results indicate that rats…
Recently, we were charged with providing a learning opportunity for high school students participating in the Upward Bound Regional Math and Science Program, a program designed to stimulate interest in mathematics and science for students from…
Tilting the viewing angle of the operating microscope during phacoemulsification provides the surgeon a better view of the cataractous lens. This technique, combined with continuous curvilinear capsulorhexis, divide and conquer nucleofractis, and…
The present study was undertaken to determine whether the diminished cardiac performance associated with cocaine administration persists after the drug has been eliminated from the body. Cocaine (5 or 10 mg/kg iv) was administered to conscious (n =…
Adult male Sprague-Dawley rats were treated with para-chlorophenylalanine (pCPA) or alpha-methyl tyrosine (alpha-MT) to study the effect of serotonin or catecholamine depletion on the expression of vasoactive intestinal peptide (VIP) messenger RNA in…
Rats selectively bred for ethanol preference, that is, alcohol-preferring (P) and -nonpreferring (NP) rats, were trained to discriminate the interoceptive stimuli produced by IP-administered 1,000 mg/kg ethanol (10% v/v) in a two-lever,…
The secretion of growth hormone (GH) is impaired in the genetically obese Zucker rat where GH gene expression and plasma GH levels are depressed; however, the underlying mechanism of this abnormality remains unclear. We have evaluated the potential…
