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…

Oxysterol 7 alpha-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 7 alpha-hydroxylase (CYP7B1)…

Background: Epidemiological data indicate that approximately 20% of children have psychosocial problems, yet less than 2% of children are seen by mental health specialists each year. Primary care physicians tend to identify children with psychosocial…

In the mustached bat, combination-sensitive neurons display integrative responses to combinations of acoustic elements in biosonar or social vocalizations. One type of combination-sensitive neuron responds to multiple harmonics of the…

The auditory cortex of the mustached bat (Pteronotus parnellii) displays some of the most highly developed physiological and organizational features described in mammalian auditory cortex. This study examines response properties and organization in…

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…

Study Design. A description of the technique for lumbar microdecompression and a prospective study of the outcomes. Objective. To describe and analyze a technique that affords an excellent decompression while minimizing damage to surrounding tissues.…

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…

A partial hominoid skeleton just older than 15 million years from sediments in the Tugen Hills of north central Kenya mandates a revision of the hominoid genus Kenyapithecus, a possible early member of the great ape-human clade. The Tugen Hills…

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…

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…

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…

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,…

At the low temperatures of the overwintering environment of the frog Rana temporaria, small changes in ambient temperature have large effects on metabolism and behaviour, especially since Q10 values are often greatly elevated in the cold. How the…

At the low temperatures of the overwintering environment of the frog Rana temporaria, small changes in ambient temperature have large effects on metabolism and behaviour, especially since Q(10) values are often greatly elevated in the cold. How the…

Amphibians overwintering in ice-covered aquatic environments encounter levels of hypoxia that present significant challenges to the maintenance of aerobic metabolism. Earlier laboratory experiments showed that cold-submerged frogs will seek out lower…

The low temperatures encountered by overwintering frogs result in a large downregulation of metabolism and behaviour. However, little is known about acid-base regulation in the extreme cold, especially when frogs become exclusive skin-breathers…

Prompt clinical diagnosis and timely treatment are the hallmarks of the proper care of diabetic patients with foot infections. The importance of careful clinical foot examination cannot be overemphasized. When infection is suspected, effort should be…

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…

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…

Study Design, Caudal vertebrae were obtained from male and female mice from two transgenic lines expressing an erythroid-specific human growth hormone-transgene construct, and gender-matched, age-matched, nontransgenic control mice. Objective. To…
