Multiple isoforms of the contractile protein myosin are present in mammalian skeletal muscles. The diversity of the heavy-chain subunits of myosin (MyHCs) in intrafusal fibers is thought to reflect a pathway of differentiation that is unique to…
The authors prospectively investigated stress in 71, mostly European American pregnant women. Conservation of Resources (COR) theory was applied to assess the impact of resource losses and gains that occur in women's lives. Resources were defined as…
N-methyl-D-aspartate receptor/channel (NMDAR) and voltage-dependent calcium channel (VDCC) antagonists applied independently reduce the magnitude of long-term potentiation (LTP) in area CA1 of the hippocampal slice preparation. When used in…
Previous anatomical studies demonstrated vagal innervation to the ovary and distal colon and suggested the vagus nerve has uterine inputs. Recent behavioral and physiological evidence indicated that the vagus nerves conduct sensory information from…
To determine the feasibility of assessing dopamine uptake using in vitro superfusion, striatal tissue from ovariectomized female rats was infused with dopamine (1 microM), nomifensine (1 mM), or a combination of dopamine and nomifensine. Treatment…
Brain slices have been responsible for the majority of advances in our understanding of the cellular aspects of altered synaptic strength underlying memory, long-term potentiation (LTP) and long-term depression (LTD), and increases and decreases,…
The limited soft-tissue envelope technique for an uninstrumented single-level posterolateral lumbar fusion has been studied in a group of 23 patients. It resulted in a solid fusion in 21 of 23 (91%) patients. Overall, 18 of 23 (78%) patients had a…
In an era of competition in health care delivery, those who pay for care are interested in supporting primarily those activities that add value to the clinical enterprise. The authors report on their 1998 project to develop a conceptual model for…
Over the last decade, the incidence of penicillin resistance among Streptococcus pneumoniae isolates has markedly increased. This trend is unsettling because infections caused by S pneumoniae are among the leading causes of morbidity and mortality in…
Career development theory provides a comprehensive model for conceptualizing the school-to-work transition. Since the 1920s, this model has guided the design of a plethora of career education methods and materials that orient, teach, coach, and…
Mycoplasma, Chlamydia and Legionella are the usual organisms considered to be the etiologic agents of 'atypical' pneumonia. Other microorganisms such as bacteria, viruses, parasites, fungi and mycobacteria can also present with atypical pneumonia…
Diploic veins (Canales diploicae), which were identified in dogs by Dupuytren more than 200 years ago (Hecker [1845] Die anatomische Verhaltnisse und Krankheiten der Venae diploicae und Vasa emissaria, Erfahrungen und Abhandlungen im Gebiete der…
OBJECTIVES: The use of laparoscopic surgical techniques for the resection of intraperitoneal malignancies has been rapidly increasing in recent years; concomitantly, tumor recurrences at trocar sites have also been reported. These reports bring into…
Five cats were trained to perform a forelimb conditioned response to a paired tone CS/shock UCS. Rubrospinal tract section ipsilateral to the trained limb was carried out following criterion CR performance. Lesion sites were identified histologically…
A WIN 35,055-2 analog, 3 beta-(4-iodophenyl)tropane-2 beta-pyrrolidine carboxamide (RTI-229), has been radiolabelled with iodine-125 by radioiododestannylation of the corresponding trimethyltin derivative using carrier-free sodium iodide-125 as the…
Over the last few years, general surgery has seen the use of more and more laparoscopic techniques in the management of common surgical problems. This expanded use is attributable not only to the excellent results seen with laparoscopic procedures…
Oxysterol 7alpha-hydroxylase has broad substrate specificity for sterol metabolites and may be involved in many metabolic processes including bile acid synthesis and neurosteroid metabolism. The cloned human oxysterol 7alpha-hydroxylase (CYP7B1) cDNA…

Slight variation in manifestation of different diseases may allow a single individual with one disease to mimic the "classic" appearance of another, as evidenced by the frequent confusion of spondyloarthropathy with rheumatoid arthritis. Analysis of…
STUDY DESIGN: A technique for lumbar decompression using spinous process osteotomies is described, and the outcomes are studied prospectively. OBJECTIVE: To describe a technique that affords a wide exposure for decompression while minimizing damage…
New fossils discovered south of the Turkwel River in northern Kenya include an associated metacarpal, capitate, hamate, lunate, pedal phalanx, mandibular fragment, and teeth. These fossils probably date to around 3.5 m.y.a. Faunal information…
Objectives: This study was performed to complement studies on spondyloarthropathy in rhesus macaques by quantifying and characterizing another major form of arthritis and contrasting it with osteoarthritis. Methods: Skeletons of 269 macaques of known…
Experiments were undertaken to determine whether angiotensin (Ang) II concentration increases during massive sympathetic nervous system (SNS) activation and whether such an increase plays a role in the pathogenesis of SNS-induced left ventricular…
The 'atypical' pathogens are important causes of pneumonia, causing illness ranging from mild to life-threatening. The most common atypical pathogens are Mycoplasma pneumoniae and Chlamydia pneumoniae; others include Legionella species, Chlamydia…
