a role of adenosine in pathogenesis of syndrome x has recently been postulated. previous studies suggest that aminophylline (an adenosine receptor blocker) improves exercise tolerance in this disorder. present study was performed to examine the efficacy of theophylline in syndrome x and to determine the incidence of cardiovascular risk factors and clinical, ecg and angiographic findings in thes...

In view of Run 4 at the LHC, presently scheduled from 2029 onwards, ALICE is pursuing several upgrades to further extend its physics reach. order improve heavy-flavor hadron and dielectron measurements which rely on secondary vertexing, a reduction material budget innermost layers Inner Tracking System needed. This can be achieved with bent pixel sensors, arranged in half-cylinder shapes integr...

UNLABELLED Exercise training results in a speeding of pulmonary oxygen uptake (VO2) kinetics at the onset of exercise in adults; however, only limited research has been conducted with children and adolescents. PURPOSE The aim of the present study was to examine VO2 and muscle deoxygenation kinetics in trained and untrained male adolescents. METHODS Sixteen trained (15 +/- 0.8 yr, VO2peak = ...

The largely unknown parton distribution functions of nuclei and the similarities observed between high-multiplicity pp pPb events compared to PbPb, often described by means hydrodynamics, are main motivations for an extended data taking program during LHC Run 3 4. future increase in luminosity combined with LHCb unique detector capabilities will allow perform new precise measurements. Moreover,...

A new species, Gnathia nkulu sp. n. is described from material collected off the South African coast at 80-200m depth. It differs from the intertidal species Gnathia africana Barnard, 1914 in that the mediofrontal process is not deeply divided into two lobes, article 2 of the pylopod is rounded and small wart-like tubercles and long simple setae are present on both the cephalosome and pereon.

The purpose of this study was to investigate the haemodynamic response to dynamic exercise after heart-lung transplantation (HLT). Nine stable HLT recipients (6 males) were studied 12-55 months after transplantation. While sitting on a cycle ergometer, they first underwent a maximal symptom-limited exercise test (power increment was 10 W x min(-1)) to determine the maximal tolerable workload. O...

Background. BDNF and NT-4/5 have been proposed to be involved in the coordinated adaptations of the neuromuscular system to the elevated level of activity, but an activity-dependent expression of neurotrophins in skeletal muscle is not well established. Objectives. We, therefore, investigated the effect of one session of resistance exercise on mRNA expression of some neurotrophins in Slow and ...

STUDY OBJECTIVES To compare the effect of montelukast and the long-acting beta(2)-agonist salmeterol on cardiopulmonary exercise economy and physical performance in adult patients with asthma during exercise. DESIGN AND PATIENTS Asthmatic patients (n = 18), aged 18 to 35 years with exercise-induced bronchoconstriction (EIB), using a double-blind, double-dummy cross-over design. Montelukast, 1...
