BACKGROUND Lower urinary tract symptoms are common among older men and 5-α reductase inhibitors (5-ARI) are a group of drugs recommended in treating these symptoms. The effect on prostate volume is mediated by a reduction in dihydrotestosterone; however, this reduction is counterbalanced by a 25% rise in serum testosterone levels. Therefore, 5-ARI use might have systemic effects and differentia...

BACKGROUND Acute respiratory infections (ARI) are one of the major problems of childhood in developing countries. The objective of the study was to obtain the incidence of ARI and its risk factors in Antalya, Turkey. METHODS We carried out a prospective cohort study on 204 infants who were born between 1 November and 31 December 1997, in the area of two primary health-care units in the Antaly...

We report the identification and functional characterization of ariadne-1 (ari-1), a novel and vital Drosophila gene required for the correct differentiation of most cell types in the adult organism. Also, we identify a sequence-related gene, ari-2, and the corresponding mouse and human homologues of both genes. All these sequences define a new protein family by the Acid-rich, RING finger, B-bo...

BACKGROUND Dynamic modulation of repolarization is important in arrhythmogenesis. An inverse relation exists in myocardium between activation time (AT) and action potential duration (APD). We hypothesized that resulting gradients of APD and diastolic interval (DI) interact with restitution properties and modulate the timing of repolarization. METHODS AND RESULTS Activation-recovery intervals ...

Background: Acute Respiratory Infection (ARI) is one of the most important causes morbidity and mortality in children under five years old (toddlers) worldwide, especially developing countries. ARI an acute upper or lower respiratory tract disease that occurs acutely, usually transmitted with mild to lethal symptoms. Various risk factors cause a high incidence cases infants, including low birth...

With respect to the fact that acute respiratory infections (hereafter ARI) are a world-wide serious social and economic problem, more and more attention is being paid to the development and application of oral bacterial immunomodulators. The preventive effect of GS Imunostim has been evaluated during the respiratory season 2005. The study took place at 10 outpatient sites of general practitione...

We present the K-band infrared spectrum of the intermediate polar XY Ari. The spectrum confirms the cataclysmic binary nature of XY Ari, showing emission lines of He I (λ2.0587 μm) and the Brackett and Paschen series of H I. The broad nature of these lines suggest an origin in an accretion disc. The spectrum is strongly reddened by absorption within the molecular cloud Lynds 1457 and shows prom...

Cerebral autoregulation refers to regulation mechanisms that aim to maintain cerebral blood flow approximately constant. It is often assessed by autoregulation index (ARI), which uses arterial blood pressure and cerebral blood flow velocity time series to produce a ten-scale index of autoregulation performance (0 denoting the absence of and 9 the strongest autoregulation). Unfortunately, data a...

Acute respiratory infections (ARI) are frequent in Inuit children, in terms of incidence and severity. A cohort of 294 children <2 years of age was formed in Sisimiut, a community on the west coast of Greenland, and followed from 1996 to 1998. Data on ARI were collected during weekly visits at home and child-care centers; visits to the community health center were also recorded. The cohort had ...

Under the hypothesis that both influenza and respiratory syncytial virus (RSV) are the two leading causes of acute respiratory infections (ARI), in this paper we have used a standard two-pathogen epidemic model as a regressor to explain, on a yearly basis, high season ARI data in terms of the contact rates and initial conditions of the mathematical model. The rationale is that ARI high season i...
