Resistance Training Acutely Impairs Agility and Spike-Specific Performance Measures in Collegiate Female Volleyball Players Returning from the Off-Se…

2020

This study examined the acute effects of resistance training (RT) on volleyball-specific performance. Sixteen female volleyball players undertook their initial, pre-season RT bout. Countermovement jump (CMJ), delayed onset of muscle soreness (DOMS), and sport-specific performances (i.e., run-up jump, agility, and spiking speed and accuracy) were measured before, 24 (T24), and 48 (T48) hours after RT. A significant increase in DOMS was observed at T24 and T48 (~207.6% &plusmn

Creatine kinase (CK) is a marker for muscle cell damage with limited potential as marker for training load in strength training. Recent exercise studies identified cell free DNA (cfDNA) as a marker for aseptic inflammation and cell damage. Here we overserved in a pilot study the acute effects during strength exercise and chronic effects of regular strength training on cfDNA concentrations over a period of four weeks in three training groups applying conservation training (CT) at 60% of the 1 repetition maximum, high intensity-low repetition training (HT) at 90% of the 1 repetition maximum and differential training (DT) at 60% of the 1 repetition maximum. EDTA-plasma samples were collected b…

Cost-efficacy of oral triptans in the treatment of acute migraine

2005

SummaryThe objective of this study was to compare the efficiency of oral triptans currently used in the treatment of acute migraine in Spain. Using a decision analytic model, a cost-efficacy analysis was performed from the payer's perspective. Efficacy was assessed in terms of sustained pain-free patients, with data extracted from a recent meta-analysis of clinical trials. Chest-related and central nervous system-related adverse events were also considered. For the economic analysis, the cost of drug treatment and the management of adverse events were determined.A group of three triptans (naratriptan 2.5 mg, sumatriptan 50 mg and almotriptan 12.5 mg) was found to dominate all other triptans…

Physiological and metabolic actions of mycophenolate mofetil on cultured newborn rat cardiomyocytes in normoxia and in simulated ischemia

2004

Mycophenolate mofetil (MMF) is a new immunosuppressive drug used to reduce acute rejection after heart transplantation. As with other immunosuppressive drugs, MMF therapy is associated with several adverse effects. However, the direct effects of MMF on myocardial tissue has not been yet evaluated. The aim of the work was thus to evaluate the effects of MMF on isolated cardiomyocytes (CM) in normal conditions and in an in vitro model of simulated ischemia (SI; substrate-free hypoxia) and reperfusion (R; reoxygenation). Myocyte-enriched cultures were prepared from newborn rat heart ventricles. The transmembrane potentials were recorded using conventional microelectrodes and the cell contracti…

Evaluation of the pulse wave arrival time as a marker for blood pressure changes in critically ill infants and children

1995

Objective. Pulse arrival time (PAT), which is the interval between the R wave of the electrocardiogram (ECG) and the arrival of the pulse wave peripherally, has been reported to be suitable for use as an indirect measure of blood pressure change. The purpose of this study was to evaluate, in critically ill infants and children, the degree to which 1/PAT covaries with systolic, diastolic, and mean blood pressure, as well as heart rate.Methods. A laboratory device was used to calculate PAT in real time from the ECG and the plethysmographic curve of pulse oximetry used for routine monitoring. Calculated PAT and corresponding blood pressures and heart rate were stored on hard disk. A total of 1…

Anaesthetic techniques to prevent perioperative stroke.

2013

Different techniques and interventions that can be used by an anaesthesiologist to minimize the perioperative stroke risk are summarized.The most important risk factors for perioperative stoke are not modifiable, for example previous stroke or renal failure, but they can be used to identify patients with a high risk for perioperative stroke. The antiplatelet therapy should be continued in patients with a high risk for cardiovascular thrombosis. This might be true even for operations in which bleeding should be strictly avoided such as eye surgery. One of the most recent neuroprotective approaches is the remote ischaemic preconditioning.Perioperative stroke increases morbidity and mortality …

24. Aminooxyacetate, an inhibitor of H2S production, potentiates lindane-induced convulsions in rats

2013

Purpose: H 2 S is a gaseous molecule recently recognized as endogenously produced neurotransmitter with different, still not well known, physiological and pathological roles. Cystathionine- β -synthase (CBS) is a major enzyme responsible for H 2 S production in the brain. The aim of this study was to investigate the effects of aminooxyacetate, potent CBS inhibitor, on convulsions induced by lindane in rats. Methods: Adult male Wistar albino rats were intraperitoneally (i.p.) treated with lindane 4 mg/kg and observed for convulsive behavioral manifestations during next 30 min. Aminooxyacetate (0.25 mmol/kg) or saline were injected 30 min prior to lindane administration. Seizure behavior was …

Brain tissue pO2 related to SjvO2, ICP, and CPP in severe brain injury

2000

The aim of this report is to present first experience in comparing the course of brain tissue oxygen pressure values (PtiO2) to changes in jugular vein oxygen saturation (SjvO2), intracranial pressure (ICP), and cerebral perfusion pressure (CPP) after severe brain injury. PtiO2 monitoring was done using a polarographic Clark type microcatheter (LICOX pO2 probe) (GMS, Kiel, Germany) with a diameter of 0.5 mm and a sensitive area 7.9 mm long inserted in a right frontal position. The microcatheter was connected to a LICOX pO2 device. A fiber-optic catheter was used to measure SjvO2 and placed into the right internal jugular vein. The ICP monitoring was performed with a fiber-optic intraparench…

Outpatient management of proctologic disease. Which techniques for local anesthesia? The experience of a single center

2019

Introduction. Since 1899 outpatient management of surgical patients had been increasing, becoming the best option when possible. In 1988 was described the first experience of outpatient management of proctologic disease. Advances in local anesthesia techniques have improved the outpatient approach to surgical disease, particularly in patients with proctological diseases. Methods. From 2010 to 2016, 1160 patients who needed surgery for proctologic disease have been recruited: 239 hemorrhoidectomies using the variant of Milligan Morgan technique described by Phillips, 45 trans-anal hemorrhoidal DE-arterialization (THD), 315 sphincterotomies, 12 anal polypectomies, 230 loop seton positions, 65…
