Objectives: To review the clinical and laboratory findings of 108 adult patients with bacteremic pneumococcal pneumonia admitted to a community hospital and to determine the value of sputum Gram stains and cultures in the diagnosis of pneumococcal…

Whether afferents exert their morphogenetic influence on spindles through release of trophic factors at intrafusal fiber junctions or via participation in proprioceptive pathways which modulate the motor activity to muscles was investigated by…

In this report the olfactory bulbs (OB) were removed from 5-6 month, 15-16 month and 25-26 month male Fischer 344 rats and assayed for concentrations of monoamines and their metabolites using HPLC-EC. Concentrations of norepinephrine were…

Anecdotal evidence suggests that the foramina of the cribriform plate which transmit cranial nerve I decrease in size with age, but this finding has never been supported with quantitative data. It has also been observed that olfactory function…

Although chronic neuropathic pain disorders are more prevalent in the senescent population, little is known about how the aging process alters the thermal hyperalgesic sensitivity to peripheral nerve injury. In this study, neuropathic pain was…

Aging differentially alters forms of long-term potentiation in rat hippocampal area CAl. J. Neurophysiol. 79: 334-341, 1998. Long-term potentiation (LTP) of the Schaffer collateral/commissural inputs to CAI in the hippocampus was shown to consist of…

Hausler & Schmid (1995) challenged the long held opinion that AL 288-1 (Australopithecus afarensis), popularly known as "Lucy," was female. They concluded that AL 288-1 was most probably male ("Lucifer") and, by extension, the hypodigm for A.…

We examined the effect of L-dihydroxyphenylalanine (L-DOPA) infusion in vitro upon dopamine (DA) and dihydroxyphenylacetic acid (DOPAC) output from superfused corpus striatum of vehicle and reserpine or tetrabenazine (TBZ) treated male rats.…

Monoamine-activated alpha-2-macroglobulin (alpha 2M) has been shown to decrease the dopamine concentrations in rat caudate putamen (CP) in vivo as well as inhibit choline acetyltransferase activities in the culture of basal forebrain neurons. In this…

The influence of brain-derived neurotrophic factor (BDNF) upon the nigrostriatal dopaminergic system was evaluated in weanling and adult mice carrying a targeted inactivated BDNF gene. Regional specificity of this BDNF mutation was assessed by…

We evaluated the ability of canine isolated nonperfused lung lobes to absorb fluid from their air spaces by simultaneously measuring alveolar liquid clearance (ALC) in three lobes removed from the same dog. Autologous plasma was instilled in the air…

Select semipermeable amphiphilic membranes have been prepared and their diffusional characteristics for glucose, insulin, and albumin investigated. The membranes were prepared by cast copolymerization of a hydrophilic monomer (i.e., N,N-dimethyl…

This article demonstrated a systematic approach to acid-base problem solving through the application of the so-called "Rules of Five." This technique was compared with other options for acid-base problem solving, namely, clinicians' use of gestalt or…

Diabetes, a syndrome characterized by high plasma glucose and low plasma insulin concentrations, is associated with somatic and autonomic neuropadiabetes as well as cardiac and vascular disorders. These consequences of diabetes significantly affect…

This document by the SAEM Public Health and Education Committee outlines the public health impact of interpersonal violence as it pertains to acute emergency care. This paper provides an overview of violence through the life cycle (i.e., child abuse,…

Intraocular eyelashes are an infrequent complication of trauma to the eye. Intraocular cilia have a variable prognosis ranging from acute inflammation to remaining dormant within the vitreous for several years. However, intraocular cilia in the…

Muscle fibers develop sequentially from several generations of myotubes that express specific isoforms of myosin heavy chain (MHC). We observed that the chicken-derived monoclonal antibody (mAb) S46 binds to myotubes of the fetal rat hindlimb in a…

Four groups were studied to determine the cooling effect at skin level of ice application over common ankle bandages and casts. The plaster cast, synthetic cast, and Ace(R) wrap dressing groups had 18 participants and the Robert-Jones dressing group…

Purpose: To compare three decision making techniques using a common clinical problem. Methods: Two recently developed methods, the analytic hierarchy process (AHP) and the analytic network process (ANP), were compared with a Markov process in the…

The purpose of this study is to critically investigate the anatomy of the deep posterior compartment of the leg, Specifically, the relationship of the deep posterior compartment to the superficial posterior compartment and their Insertion onto the…

Historians have suggested that US president Andrew Jackson (1767-1845) experienced lead and mercury poisoning following his therapeutic use of calomel (mercurous chloride) and sugar of lead (lead acetate). To evaluate these claims, we performed…

Recent molecular studies are inconsistent with ungulate phylogenetic trees that are based on morphological traits. These inconsistencies especially relate to the position of cetaceans and perissodactyls. Evaluation of the close phylogenetic ties…

An anomalous phase transition with a marked rise in specific heat, the isobaric thermal expansion coefficient, and the compressibility coefficient at 62.5 degrees C for an equimolar mixture of 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE)…

PURPOSE: To examine parental perceptions and behaviors with regard to teen smoking, comparing African-American and white parents, and those who did and did not smoke. METHODS: Focus groups consisting of African-American and white parents who smoked…

Antipseudomonal penicillins retain most of the antibacterial activity of penicillin and aminopenicillins. This group of penicillins has added activities against many gram-negative rods, including P. aeruginosa. Similar to the earlier penicillins,…
