The hand therapist's role in the prevention and management of upper extemity injuries in the modern mass production industrial setting.

Background: This case study presents the role of an onsite hand therapist (Certified Hand Therapist, Occupational Therapist, Physical Therapist) in an industrial setting and the services that can be provided in this comprehensive care model. Onsite hand therapists can impact on Occupational Safety and Health Administration (OSHA) first aid programs and can provide state of the art treatment for the injured worker in both a direct and indirect capacity.

Purpose: The purpose of this case study article is to review the many potential services the hand therapist can offer to facilitate the return-to-work of injured employees and provide employers with a proactive case management and state-of-the-art ergonomic prevention, improving profit margins and facilitating safe work environments.

Grip strength is more sensitive to changes in elbow position than isolated wrist extension strength in patients with lateral elbow tendinopathy.

Study Design: This is an observational study.

Introduction: Because isometric wrist extension minimizes the effects of other muscles, the sensitivity of wrist extension strength testing on patients with lateral elbow tendinopathy (LET) should be evaluated.

Purpose Of The Study: The purpose of the study was to compare the effects of the elbow position on wrist extension and grip strength in patients with LET.

Neonatal hypoxia, hippocampal atrophy, and memory impairment: evidence of a causal sequence.

Neonates treated for acute respiratory failure experience episodes of hypoxia. The hippocampus, a structure essential for memory, is particularly vulnerable to such insults. Hence, some neonates undergoing treatment for acute respiratory failure might sustain bilateral hippocampal pathology early in life and memory problems later in childhood.

Daily rhythmicity of large-conductance Ca2+ -activated K+ currents in suprachiasmatic nucleus neurons.

Neurons within the suprachiasmatic nucleus (SCN) comprise the master circadian pacemaker in mammals. These neurons exhibit circadian rhythms in spontaneous action potential frequency and in the transcription of core circadian clock genes, including Period1 (Per1). Targeted electrophysiological recordings from SCN neurons marked with a green fluorescent protein (GFP) reporter of Per1 gene transcription have previously indicated that K(+) currents are critically involved in the expression of neurophysiological rhythmicity.

Mechanisms underlying episodic gonadotropin-releasing hormone secretion.

The episodic secretion of gonadotropin-releasing hormone (GnRH) is crucial for fertility, but the cellular mechanisms and network properties generating GnRH pulses are not well understood. We will explore three primary aspects of this intermittent hormonal signal: the source of rhythm(s), the possible mechanisms comprising oscillator(s), and how GnRH neurons are synchronized to produce a pulse of hormone release into the pituitary portal blood. Current knowledge will be reviewed, and hypotheses and working models proposed for future studies.
