BACKGROUND AND PURPOSE In acute ischemic stroke, large early infarct size estimated by the Alberta Stroke Program Early CT Score (ASPECTS) is associated with poorer outcomes and is a relative contraindication for recanalization therapies. The state of the intracranial collateral circulation influences the functional outcome and may be a variable to consider before thrombolysis. We evaluated the...

background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...

Recordings of biological signals such as vibrocardiography often contain contaminating noise. Noise sources may include respiratory, gastrointestinal, and muscles movement, or environmental noise. Depending on individual physiology and sensor location, the vibrocardiographic (VCG) signals may be obscured by these noises in the time-frequency plane, which may interfere with automated characteriz...

Selecting patients with severe acute pancreatitis as early as possible after the onset of symptoms is crucial for appropriate treatment [1]. The guidelines indicate that the assessment of severity should be carried out as soon as possible by a scoring system, such as Acute Physiology and Chronic Health Evaluation (APACHE) II which is a grade A recommendation [2, 3]. The comment added by the aut...

Important genetic influence on intervertebral disc degeneration has been shown previously. However, the role of the disc in pain production is not clear and the genetic influence on the development of the symptoms of low back pain is largely unknown. Therefore, data on lifetime prevalence of low back pain from the young cohort in The Danish Twin Registry (aged 12-41) were analyzed with respect ...

BACKGROUND Household cleaning and pesticide products may contribute to breast cancer because many contain endocrine disrupting chemicals or mammary gland carcinogens. This population-based case-control study investigated whether use of household cleaners and pesticides increases breast cancer risk. METHODS Participants were 787 Cape Cod, Massachusetts, women diagnosed with breast cancer betwe...

the complex formation reaction between iodine with tetrabutylammonium halides (tbax) has been studied spectrophotometrically in chloroform solution at 25ºc. various aspects of the spectra of iodine in the presence of various concentration of different tetrabutylammonium halides have been discussed in terms of electronic specifications of iodine and halides. in the case of tetrabutylammonium iod...

introduction emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of autism spectrum disorders (asd). the ratios of the lengths of the bones of the 2nd to the 4th digits (2d:4d) are purported to be markers for prenatal androgen exposure and to be established early in gestation. ratio of second and fourth digits (2d:4d)  is usually used as a proxy for prenatal t...

it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...
