Background: Congenital cytomegalovirus (cCMV) is the most common congenital viral infection in the United States. Symptomatic infections can cause severe hearing loss and neurological disability, although ~ 90% of cCMV infections are asymptomatic at birth. Despite its prevalence, the long-term neurobehavioral risks of asymptomatic cCMV infections are not fully understood.

Over the past several decades, the development of organocatalytic ring-opening polymerization (OROP) has made the synthesis of many new types of biodegradable polymers possible. In this research article, the first example of an oxygen atom transfer reagent pendant on a biodegradable polymer backbone is reported.

When oxidized with an iodosoarene oxygen atom transfer (OAT) reagent, kinetic studies demonstrate that the nitrile ligand does not dissociate before reacting. Instead, OAT to the central nitrile carbon is implicated (nitrile oxidation), and is further supported by the product of the reaction, -acyl-dimethylsulfoximine.

The target audience for each topic varies, but the majority of them apply to all disciplines such as direct patient care roles (emergency room technicians, nurses, paramedics, advanced practice practitioners, resident physicians, attending physicians, etc.) and emergency department clerks/coordinators.

During the school-aged years, families can support children's development of health behaviors and family routines. This interdisciplinary study examined families' experiences of mealtimes and the factors that support or hinder mealtime participation.

A qualitative research approach elicited rich, decision making experiences of families.
Methods: Structured family interviews (n=21) in spring 2011 in Oklahoma City captured direct quotations about family beliefs and practices related to BTV.
The purpose of the study was to compare blood lactate and hormonal responses with flywheel ergometer (FERG) leg presses for preliminary assessment of workouts best suited for future in-flight resistance exercise. Comprised of 10 repetition sets, the workouts entailed 3 sets of concentric and eccentric (CE3) actions, or concentric-only actions done for 3 (CO3) or 6 (CO6) sets. Methods employed included assessment of blood lactate concentrations ([BLa-]) before and 5 minutes postexercise.

Improvements in acceleration often entail workouts done at intensities that elicit higher blood lactate concentrations (BLa). The purpose of the study is to assess the impact of acceleration on BLa.

Methods: To assess the ability of variables to predict GH variance from resistive exercise done on a flywheel ergometer (FE) designed for in-flight exercise, subjects (N=17) performed three types of workouts on the device.
To assess anthropometry as a predictor of high-speed performance, subjects performed four seated knee- and hip-extension workouts with their left leg on an inertial exercise trainer (Impulse Technologies, Newnan GA). Workouts, done exclusively in either the tonic or phasic contractile mode, entailed two one-minute sets separated by a 90-second rest period and yielded three performance variables: peak force, average force and work. Subjects provided the following anthropometric data: height, weight, body mass index, as well as total, upper and lower left leg lengths.
View Article and Find Full Text PDFA high-speed, low-resistance inertial exercise trainer (IET, Impulse Training Systems, Newnan, Ga) is increasingly employed in rehabilitative and athletic performance settings. Repetitions on an IET are done through a large range of motion because multijoint movements occur over more than one plane of motion, with no limitation on velocities or accelerations attained. The current study purpose is to assess data reproducibility from an instrumented IET through multiple test-retest measures.
View Article and Find Full Text PDFLeptin, the product of the ob gene, has been shown to reduce fat mass, food intake, hyperglycemia, and hyperinsulinemia and to increase whole-body glucose disposal. However, it is unknown if leptin improves insulin action in skeletal muscle. Therefore, the purpose of this investigation was to determine if chronic leptin administration increases insulin-stimulated skeletal muscle glucose uptake and transport.

Peritoneal macrophages were elicited by Freund's incomplete adjuvant from adult male and female Fisher 344 rats. The release of prostaglandin E2 and thromboxane B2 from these macrophages was determined by radioimmunoassay. The basal release of these products was the same for males and females.

Pretreatment with indomethacin (50 mg/kg), verapamil (40 mg/kg) or nifedipine (4 mg/kg) failed to inhibit the lethal effect of 20 micrograms/kg PAF-acether. This suggests that neither arachidonate cyclo-oxygenase products nor availability of extracellular Ca2+ mediate the toxic action.

In contrast, gender differences were not observed in the response to noradrenaline of 5-hydroxytryptamine. In previous studies, testosterone unlike oestrogen or progesterone, increased the response of both rabbit and rat aorta to U46619.
