Acute effects of cold pack on mechanical properties of the quadriceps muscle in healthy subjects.
2012
Purpose: To examine the effects of local cooling on mechanical properties of the quadriceps muscle in healthy subjects. Subjects: Thirty-nine healthy subjects (27 women, 12 men, mean age 39, range 20e62) volunteered. Methods: A cold gel pack was applied to the quadriceps muscle for 20 min. Properties were quantified by analyzing the frequency (tension), decrement (elasticity) and stiffness of damped oscillations and the compliance of the muscle before, immediately after and after 15-min after cooling. Results: The largest responses immediately after cooling were seen in the oscillation decrement parameter, 7.9 (3.7e12.1) %, and in the compliance parameter, � 7.5 (� 9.8 to � 5.3) %. Response…
Presentation and outcome of tuberculous meningitis in adults in the province of Castellon, Spain: a retrospective study
2008
SUMMARYThe aim of this study was to describe the epidemiological and clinical features of tuberculous meningitis in the province of Castellon, Spain. Retrospective analysis was done of all cases attended during the last 15 years. The following groups of variables were assessed: sociodemographic data, medical antecedents, clinical presentation, imaging study results, analyses, cerebrospinal fluid microbiology, treatment, and outcome. Twenty-nine cases were included. Median of age of patients was 34 years, and 17 (59%) were males. HIV infection was present in 15 cases (52%), fever, the most common symptom, occurred in 27 (93%), nuchal rigidity was noted in only 16 (55%), and syndrome of inapp…
New Hyperekplexia Mutations Provide Insight into Glycine Receptor Assembly, Trafficking, and Activation Mechanisms*
2013
Hyperekplexia is a syndrome of readily provoked startle responses, alongside episodic and generalized hypertonia, that presents within the first month of life. Inhibitory glycine receptors are pentameric ligand-gated ion channels with a definitive and clinically well stratified linkage to hyperekplexia. Most hyperekplexia cases are caused by mutations in the α1 subunit of the human glycine receptor (hGlyR) gene (GLRA1). Here we analyzed 68 new unrelated hyperekplexia probands for GLRA1 mutations and identified 19 mutations, of which 9 were novel. Electrophysiological analysis demonstrated that the dominant mutations p.Q226E, p.V280M, and p.R414H induced spontaneous channel activity, indicat…
