alpha 2-Macroglobulin (alpha 2M) is a rather ubiquitous protein in extracellular spaces of mammals. It is an inhibitor of endopeptidases, can be modified by aliphatic amines, and combines with a number of hormones/cytokines such as beta-nerve growth…

Cocaine abuse may lead to serious cardiac complications, including myocardial ischemia and infarction, myocarditis, cardiomyopathy and arrhythmias. With concomitant use of alcohol and cocaine, cocaethylene is produced by hepatic transformation.…

We examined the distribution of immunoreactivity to serotonin (5-HT), leu-enkephalin (LENK), tyrosine-hydroxylase (TH), and substance P (SP) within the primary visceral sensory region of cartilaginous fish. Two genera of sharks, Squalus and…

In the present experiment we tested the effects of L-DOPA upon dopamine (DA) efflux in vitro from superfused corpus striatal tissue fragments in medium containing reserpine. The purposes of this experiment were first, to evaluate the effects of…

We studied the ability of internal medicine residents to recognize depressive symptoms in a population of lower socio-economic primary care patients. Four hundred twenty patients completed the short form of the Beck Depression Inventory (BDI).…

Rats selectively bred for high alcohol sleep times (HAS) and those that are less affected (LAS) by hypnotic doses (3.0-3.6 g/kg) of ethanol were tested for differential responses to the aversive effects of 1.0 g/kg ethanol in a conditioned place…

The aim of this study was to examine: (1) whether long-term potentiation (LTP) can be induced in slices from adult rat visual cortex under conditions where inhibition is not antagonized, and (2) the role of N-methyl-D-aspartate (NMDA) receptors in…

In the present experiment peri-pubertal female mice were treated with a partially purified puberty accelerating urine extract (PAUE). Mice treated with the PAUE showed an advance in the onset of puberty as indicated by significantly increased uterine…

Male retired breeder C57/Bl and CD-1 mice were treated with either MPTP or its vehicle. At 7-10 days post-treatment, catecholamine concentrations within the olfactory bulbs (OB) and hypothalamus were determined. Norepinephrine concentrations within…

In rats, restraint exposure potentiates the magnitude and duration of analgesia following both the peripheral and intracerebroventricular administration of several opioid agonists as compared to non-stressed controls. It has been suggested that the…

We determined whether the solvent drag reflection coefficient (sigma f) for total proteins of a canine perfused left lower lung lobe (LLL) preparation decreases at elevated venous pressures (Pv). We found that sigma f (estimated using the…

Addition of the aromatic amino acid decarboxylase inhibitor, NSD-1015 (10 microM), to Krebs'-Ringer phosphate (KRP) superfusion medium, significantly increased the release of dopamine in vitro from superfused corpus striatum tissue fragments of male…

Rewards, as diverse as food, sweetened solutions, copulation, electrical brain stimulation, and drugs abused by humans, have been shown to condition place preferences in rats. Juvenile rats will readily learn to traverse a T-maze for the opportunity…

Ovariectomized Syrian hamsters treated by female sex steroids during a 1-month period show gallbladder surface epithelial changes in the fundic area consistent with apical bulging and decapitations of the epithelial cells. These events were detected…

Human papillomavirus (HPV) type 16 DNA was found in three separate neoplastic lesions within a female patient. The physical state of the viral DNA in each lesion was determined by two-dimensional agarose gel electrophoresis. The primary cervical…

Rats were trained to discriminate IP administration of 800 micrograms/kg cathinone using a food-motivated, two-lever discrimination procedure. Following training, 800 micrograms/kg cathinone discrimination was produced (generalized) by lower…

Rats were trained to discriminate the interoceptive stimuli produced by subcutaneously administered 0.4 mg/kg nicotine in a two-lever, food-motivated, operant task. Once criterion performance was attained, dose-response experiments indicated an ED50…

Cocaine has repeatedly been shown to produce conditioned place preference (CPP) in the rat. The present study employed the heterogenous N/Nih rat stock to produce a selectively bred rat line determined by individual place preference to a conditioning…

Seventh-generation selectively bred high-alcohol-drinking (HAD) and low-alcohol-drinking (LAD) rats were trained to make differential responses for ethanol (0.75 g/kg, IP) and saline vehicle, following postadministration intervals (PI) of 2 min…

Rats were trained to discriminate the stimulus properties of the benzodiazepine receptor partial inverse agonist beta-carboline-3-carboxylate acid methyl amide (FG 7142) (5.0 mg/kg) or the alpha 2-adrenergic receptor antagonist 17…

We have sequenced about 5 kb of the Escherichia coli chromosome downstream from the tolC gene, looking for a topoisomerase gene. This region does not contain a topoisomerase gene.

The objective of the present experiment was to demonstrate whether four days of twice-a-day conditioned place conditioning produces a preference that is equivalent to that produced by using eight days of once-a-day training. Two doses of the…

The possibility that zinc (Zn2+) induces giant depolarizing potentials (GDPs) by blocking pre- and postsynaptic gamma-aminobutyric acidB (GABAB) receptors in area CA1 of rat hippocampal slices was investigated. Monosynaptic GABAA receptor-mediated…

1. Male Sprague-Dawley rats were fitted with intrathecal (i.t.) and intracerebroventricular (i.c.v.) catheters. Fentanyl was injected either i.t. or i.c.v., and the antinociceptive efficacy of fentanyl was evaluated using the tail-flick…

We previously reported that an N-methyl-D-aspartate receptor-independent component of long-term potentiation with an apparent delayed onset can be induced in area CA1 of the hippocampus. Here we show that some but not all of this delay in onset can…

There is a widespread practice among people living in Eastern Africa and Southern Arabia of chewing the leaves of the Khat shrub so as to produce pharmacological effects that are practically indistinguishable from those produced by amphetamine…

Recent reports cite results that both cocaine-induced conditioned place preference and activity stimulation are attenuated by pretreatment with the calcium channel blocker isradipine (ISR) in rats. By blocking voltage-dependent

The drug discrimination paradigm (DD) was used to evaluate behavioral differences of rats selectively bred for differential ethanol drinking preferences. Seventh-generation high alcohol-drinking (HAD) and low alcohol-drinking (LAD) rats were trained…

Fourteenth generation high alcohol-sensitive (HAS) and low alcohol-sensitive (LAS) rats were trained to discriminate the effects of 600 mg/kg intraperitoneally administered ethanol from its vehicle at 6 and 30 min postadministration. Each of the…

The conditioned place preference (CPP) test and spontaneous motor activity were used in order to determine if ethanol-preferring (P) rats differ from ethanol nonpreferring (NP) rats after the administration of a moderate (1.0 g/kg) dose of ethanol.…

The present study examined the possible role of extracellular Ca(2+) in triethyltin (TET) neurotoxicity in area CA1 of the rat hippocampal slice. Slices were exposed to 20 mum-TET-Br for 30 min in an environment of normal or no extracellular Ca(2+),…

OBJECTIVES: To evaluate paramedics' ability to identify elderly at risk and refer them for assessment and service. DESIGN: A prospective nonrandomized open trial. SETTING: Akron, Ohio, a midsize city with a well-developed advanced life support…

STUDY OBJECTIVE: To sample the practice styles of emergency physicians caring for acute traumatic wounds. DESIGN: Written survey. SETTING: US emergency departments obtained from the American College of Emergency Physicians mailing list. SUBJECTS:…

When Mg2+ or ethidium bromide (EB) were combined with poly r(A-U) at a ligand/ribonucleotide ratio of 1/4, the antiviral activity of the Mg2+ and EB increased 136-fold and 154-fold. Eriochrome Blue SE was employed to visualize the subcellular…

This study of 3,318 outpatient visits evaluated the influence of the physician-assessed level of patient motivation on the level of physician involvement in follow-up care. Data collected included patient demographics, health risk factors,…

This paper briefly reviews the benefits of using age-progression techniques in hypnotherapy, followed by a detailed explanation and illustration of the "back-from-the-future" technique with two case examples, including their outcome. The patients…
