background consumption of home-distilled alcohol may lead to epidemic or sporadic cases of severe acute methanol poisoning. the difficulty of establishing strict indications for hemodialysis in acute methanol poisoning is a widely recognized issue. materials and methods the determination of the clinical, especially hemodialysis, and para clinical factors influencing patient survival in 46 acute...

We assessed the changes in arterial potassium concentration during exercise and recovery in relation to exercise tolerance in patients with impaired exercise tolerance. Sixteen patients with cardiac disease were subjected to a cardiopulmonary exercise test on a cycle ergometer. Arterial potassium and lactate concentrations were measured every minute during and after exercise, and ventilatory th...

Anaerobic threshold which describes the onset of systematic increase in blood lactate concentration is a widely used concept in clinical and sports medicine. A deflection point between heart rate-work rate has been introduced to determine the anaerobic threshold non-invasively. However, some researchers have consistently reported a heart rate deflection at higher work rates, while others have n...

The donor-acceptor ground-state charge-transfer complex (CTC) formed in solution between a conjugated polymer, poly[methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene-vinylene] (MEH-PPV), and a low-molecular-weight organic acceptor, 2,4,7-trinitrofluorenone (TNF), is studied by optical absorption and Raman spectroscopy. The CTC absorption as a function of TNF content shows a threshold increase that is ...

Human serum albumin has been used as a model protein for protein folding and ligand binding studies over many decades. Due to its long life period and high concentration in plasma, HSA is highly sensitive to glycation. It is reported that 175 mg/dL glucose concentration is a threshold of kidney activity for the beginning of excretion of glucose. pH denaturation of HSA in absence and presence of...

A Yb-doped silica microcavity laser on a silicon chip is fabricated from a solgel thin film. The high-Q micro-toroid cavity, which has a finesse of 10,000, is evanescently coupled to an optical fiber taper. We report a threshold of 1.8 microW absorbed power that is, to the best of our knowledge, the lowest published threshold to date for any Yb-doped laser. The effect of Yb(3+) concentration on...

tion on the damaged area of the heart surface , we noted the following results'). Immediately after injury, the ST-elevation was, of course, recorded in the direct unipolar electrocardiogram taken from the injured heart surface . This elevation of the ST-segment was not eliminated even when potassium-free solution was poured on the injured region. As time passed, however, it did not make the ST...

AIM This was to validate a taste test on healthy school children. A cross-sectional study was designed to perform a standardised clinical evaluation of the gustatory sensitivity. MATERIALS AND METHODS Forty (18 males and 22 females) children were selected. Inclusion criteria were age between 5 and 12 years, absence of systemic disease and no antibiotic treatment in the last six months. The...
