We examined whether neurons in the inferior colliculus of the mustached bat (Pteronotus parnellii) are combination sensitive, responding to both low- and high-frequency components of the bat's sonar signal. These neurons, previously reported in the…
Objectives: To test whether dopamine infusion improves oxygen delivery (D over dot O-2) and oxygen uptake (V over dot O-2) in hyperdynamic septic shock patients stabilized by adequate volume and dobutamine alone, or by the combination of dobutamine…
The reliability of visual examination of defleshed bones was assessed for detection of postcranial metastatic disease in individuals known to have had cancer. This was compared with standard clinical radiologic techniques. The skeletons of 128…
Twentieth-century vocational guidance has been an objective enterprise in which counselors have studied and treated career indecision by abstracting and objectifying it. This article describes how the logical positivist perspective on indecision as…
Dominant mutations in the fibroblast growth factor receptor 2 (FGFR2) gene have been recently identified as causes of four phenotypically distinct craniosynostosis syndromes, including Crouzon, Jackson-Weiss, Pfeiffer, and Apert syndromes, These data…
Behavioral and neurochemical indexes of nigrostriatal dopaminergic function were compared between sedentary control rats (n = 12) and daily spontaneous running (DSR) male rats (n = 10). Nine weeks of DSR did not significantly alter body, heart,…
Exercise training attenuates arterial baroreflex function. Mechanisms responsible may include an attenuated aortic baroreceptor reactivity (afferent mechanisms) and/or an attenuated central baroreflex gain. We tested the hypothesis that the aortic…
Because experience in our newborn intensive care unit follow-up clinic since 1982 suggested that immunizations of newborn intensive care unit graduates in the first 2 years of life were inappropriately delayed, questionnaires were sent to families…
A sample of 192 financially impoverished, inner-city women was assessed for clinical depression twice during pregnancy and once postpartum. At the first and second antepartum interviews, respectively, 77.6% and 24.5% of the women were depressed,…
The present study describes the development and an initial assessment of the psychometric properties of the Decisional Process Inventory (DPI). The DPI served as an empirical test of Gestalt therapy homeostasis theory for conceptualizing and…
In hippocampal area CA1, long-term potentiation (LTP) is induced by tetanic stimulation protocols that activate N-methyl-D-aspartate (NMDA) receptors. In addition, some stimulation protocols can induce LTP during NMDA receptor blockade. An initial…
OBJECTIVE: To characterize the problems facing emergency medicine residency directors (EMRDs), to describe potential solutions, and to associate perceptions with anticipated duration in the position of EMRD. METHODS: A confidential questionnaire was…
This study constitutes the first report of a calcium channel blocker used as a drug capable of controlling differential responding in a drug-discrimination paradigm. Male Sprague-Dawley rats were trained to discriminate between intraperitoneally…
The primary objective of this research project was to study the role of sex steroids in the pathogenesis of cholelithiasis using the Syrian hamster as a model. In addition to the morphological examination of the gallbladder epithelium, we thought it…
We tested the hypothesis that the reflex inhibition of heart rate (HR) during mechanical (acute bolus injection of 0.5% and 2% of estimated blood volume) and chemical (phenylbiguanide, PBG, 2.5 and 5 micrograms.kg-1) stimulation of cardiopulmonary…
Objective: The purpose of this study was to determine if intravenous push metoclopramide would facilitate immediate transpyloric passage of a small-bore feeding tube without fluoroscopy or endoscopy. Design: Prospective, randomized trial. Patients:…
Neck masses in children may be inflammatory, neoplastic or congenital. Although most of these masses are benign inflammatory nodes, an asymptomatic neck mass is the most common presentation of head and neck malignancies in children. Cystic lesions…
The present article seeks to renovate the career counseling use of interest inventories as personality indicators by making explicit the link between inventoried interests and their personal meaning to clients. Interest denotes a relationship between…
Whether any fibers in rat hindlimb muscles express alpha-cardiac myosin heavy chain (MHC) is uncertain. Expression of alpha-cardiac MHC mRNA and the polypeptide for which it codes were examined in control and denervated rat muscle spindles using in…
Background/Aims: The decrease in cholesterol 7 alpha-hydroxylase induced by intraduodenal infusion of taurocholate in bile fistula vats may be indirect, i.e., mediated through release or absorption of an intestinal factor in response to the presence…
The omega-hydroxylation of fatty acids by certain cytochrome P450 enzymes shows a degree of chain-length and regiospecificity which is remarkable in view of the conformational flexibility of these substrates, the strong similarity in properties among…
Statisticians continue to write about interpersonal problems they experience as consultants. In the past, they have suggested that some clients create a conflict-ridden process. More recently, they have been looking at themselves and their training…
Scanning (SEM), and transmission (TEM) electron microscopy were used and correlated to morphologically characterize changes induced in the gallbladder epithelium of female Syrian hamster in response to treatments with estradiol (E) alone, and…
