to determine the prevalence of pituitary hormone deficiencies after moderate traumatic brain injury (tbi). we conducted a prospective cohort and included 75 patients with moderate tbi with gcs between 9 and 13 who referred to emergency department of shariati hospital, tehran/iran, during 2004-2007. pituitary hormones were assessed 3 and 6 months after injury. in 3rd month post-injury, 39 cases ...

This study was conducted to investigate the scenario of buffalo production and reproduction under different farming systems at Subarno Char, in the coastal area of Bangladesh. A total of 14 farms were randomly selected and studied for various traits live weight (LW); daily milk yield (DMY); lactation length (LL); lactation production (LP); calving interval (CI); gestation length (GL); post part...

BACKGROUND Evidence on physical activity (PA) and transitions out of full-time employment in middle-to-older age is mainly cross-sectional and focused upon retirement. The purpose was to examine trajectories in PA before and after transitions out of full-time employment. METHODS Data were obtained for 5,754 people in full-time employment aged 50-75 from the US Health and Retirement Survey. Lo...

BACKGROUND The 5th Joint Task Force European guidelines on cardiovascular disease (CVD) prevention recommend the measurement of carotid intima-media thickness (CIMT) in asymptomatic individuals at moderate risk (Class IIa). We aimed to evaluate the ability of CIMT to further risk stratify patients. DESIGN Cross-sectional study. METHODS Patients aged over 18 years free of known CVD at modera...

Methods Totally 29 consecutive FMF male patients at attack free period and 17 male controls were included into the study. Physical examination (PE) was performed to detect Achilles enthesitis and/or retrocalcaneal bursitis, knee arthritis. US of the lower extremity were performed bilaterally. Grey-scale (GS) and power Doppler (PD) scores on a 0–2 semi-quantitative scale (0: no, 1: mild, 2: mode...

Bronchial secretions from 21 patients with moderate to severe chest infections were obtained by transtracheal aspiration. Six seriously ill patients showed greatly increased levels of amylase activity in the bronchial secretions compared with those found in the 15 less ill patients. This amylase was almost certainly derived from oropharyngeal contents and its presence suggests that aspiration m...

The primary contribution of this work lies in the derivation of the exact characteristic function (and hence, the mean and variance) of the capacity of multiple-input multiple-output (MIMO) systems for semi-correlated flat-fading channels. A Gaussian approximation to the exact capacity results is suggested and evaluated for its accuracy. We show that over a range of correlation levels this appr...

An analytical framework for modeling the performance of a single TCP session in the presence of random packet loss is presented that is based on a semi-Markov model for the window size evolution. The model predicts the throughput for LANs/WANs (low and high bandwidth-delay products) with good accuracy, as compared against simulation results with ns simulator. Generally, higher speed channels ar...
