STUDY OBJECTIVES The purpose of the present study was to compare in awake and asleep healthy subjects, under nasal intermittent positive pressure ventilation (nIPPV) with a two-level intermittent positive pressure device (two-level nIPPV), the efficacy of the controlled and spontaneous modes, and of different ventilator settings in increasing effective minute ventilation (VE). PARTICIPANTS Ei...

OBJECTIVE the management of asymptomatic femoral aneurysms remains controversial. The purpose of this study was to investigate the relation between the diameter of true and anastomotic aneurysms and the risk of rupture. DESIGN retrospective study. MATERIAL AND METHODS we reviewed the case records of 17 patients who underwent 17 arterial reconstructive procedures for true femoral aneurysms. ...

The longitudinal relationship between stunting and wasting in children is poorly characterized. Instances of wasting or poor weight gain may precede linear growth retardation. We analyzed longitudinal anthropometric data for 1599 children from 8 cohort studies to determine the effect of wasting [weight-for-length Z-score (WLZ) < -2] and variability in WLZ in the first 17 mo on length-for-age Z-...

Although it is an invasive and unpleasant procedure, esophagogastroduodenoscopy (EGD) is still the gold standard for esophageal varices (EV) detection. The aim of this study was to investigate liver stiffness measurement (LSM) and spleen diameter as simple noninvasive tools for EV prediction in chronic hepatitis C patients (CHC).A total of 123 Egyptian patients with CHC have been included and w...

The normal growth pattern of female C57BL/6J mice, from 5 to 30 weeks of age, has been investigated in a longitudinal study. Weight, body surface area (BS), and body mass index (BMI) were evaluated in forty mice. Lean mass and fat mass, bone mineral content (BMC), and bone mineral density (BMD) were monitored by dual energy X-ray absorptiometry (DEXA). Weight and BS increased linearly (16.15 ± ...

The main objective of this study was to estimate the proportion of total genetic variance attributed to a quantitative trait locus (QTL) on Bos taurus autosome 6 (BTA6) for milk production traits in the German Holstein dairy cattle population. The analyzed chromosomal region on BTA6 spanned approximately 70 cM, and contained 6 microsatellite markers. Milk production data were obtained from rout...

The Cerenkov counters in TASS0 consist of 3 elements, one filled with aerogel and two with Freon 114 and CO2. The 1700 liters of aerogel cover an area of 11.8m2 with a thickness of 13.5 to 18 cm. Most cells are filled with an index of refraction between 1.023 and 1.026. In a running period of 2 months after installation = 3.9 + 0.2 photoelectrons were observed. The mean valu: over 17 months...
