Sparing R, Dafotakis M, Buelte D, Meister IG, Noth J. Excitability of human motor and visual cortex before, during, and after hyperventilation. J Appl Physiol 102: 406–411, 2007. First published September 21, 2006; doi:10.1152/japplphysiol.00770.2006.—In humans, hyperventilation (HV) has various effects on systemic physiology and, in particular, on neuronal excitability and synaptic transmissio...

BACKGROUND Hallux valgus (HV), a common structural foot deformity, can cause foot pain and lead to limited mobility. The purpose of this study was to evaluate differences in plantar pressure and force during gait by HV status in a large population-based cohort of men and women. METHODS A trained examiner performed a validated physical examination on participants' feet and recorded the presenc...

Racial disparities have been suggested in hospital utilization and outcome for lung cancer surgery, but the effect of hospital centralization on closing this gap is unknown. We hypothesized that centralization has increased the utilization of high- or very-high-volume (HV/VHV) hospitals, a proxy for access to high-quality care, over the study period independently from race.Inpatient records wer...

Hydroa vacciniforme (HV) is a photosensitivity disorder characterized by recurrent necrotic vesiculopapules on sun-exposed areas, which heal spontaneously during adolescence. Recently, an association has been reported between latent Epstein-Barr virus (EBV) infection and atypical HV-like eruption and malignant potential. However, latent EBV infection has also been reported in the setting of typ...

Aim. Ventilation with pure oxygen (hyperoxic ventilation: HV) is thought to decrease whole body oxygen consumption (VO2). However, the validity and impact of this phenomenon remain ambiguous; until now, under hyperoxic conditions, VO2 has only been determined by the reverse Fick principle, a method with inherent methodological problems. The goal of this study was to determine changes of VO2, ca...

INTRODUCTION Spontaneous pneumothorax (SP) is broken down into primary (PSP: no known underlying lung disease), secondary (SSP: known lung disease) and from trauma or iatrogenic pneumothorax (IP). Current treatments include a conservative approach, needle aspiration, chest drain, suction and surgery. A Heimlich valve (HV) is a lightweight one-way valve designed for the ambulatory treatment of p...

Effect of increasing blood viscosity during extreme hemodilution on capillary perfusion and tissue oxygenation was investigated in the awake hamster skinfold model. Two isovolemic hemodilution steps were performed with 6% Dextran 70 [molecular weight (MW) = 70,000] until systemic hematocrit (Hct) was reduced by 65%. A third step reduced Hct by 75% and was performed with the same solution [low v...

The effect of human interferon on single-cycle replication of Herpesvirus hominis type 1 (HV-1) and vesicular stomatitis virus (VSV) in human foreskin fibroblast cultures (HFF) was studied. After treatment of HFF cultures with low concentrations (58 U) of human interferon, a variable but statistically significant inhibition of HV-1 was observed. At higher concentrations (greater than 95 U) yiel...
