Background: Premature infants with respiratory distress syndrome (RDS) are in dire need of respiratory support with a ventilator. However, the high tidal volume of mechanical ventilation may cause lung injury, and researchers have been concerned with the use of nasal continuous positive airway pressure (NCPAP). NCPAP has concomitant side effects, such as abdominal distention, which might disrup...

conclusions organ transplantation and treatment of transplanted patients with immunosuppressive drugs would prone them to various unusual infections. one of these is unusual primary involvement of liver by tuberculosis which has been extremely rare in the previous reports. introduction recipients of liver transplantation are prone to different types of infections such as tuberculosis (tb). case...

Soil erosion is a severe and continuous environmental problem caused mainly by natural factors, which can be enhanced anthropogenic activities. The morphological relief with relatively steep slopes, the dense drainage network, Mediterranean climate are some of factors that render Paleochora region (South Chania, Crete, Greece) particularly prone to soil in cases intense rainfall events. In this...

Prone positioning is a conventional method to enhance oxygenation in Acute Respiratory Distress Syndrome (ARDS) patients who need mechanical ventilator . It is proven that oxygenation is significantly more beneficial in prone position compared to the supine position. Furthermore, numerous evidences have confirmed that prone positioning could prevent lung injuries caused by ventilators

3-Nitrobenzanthrone (3-NBA), a potent mutagen and suspected human carcinogen, is a common environmental pollutant. The genotoxicity of 3-NBA has been associated with its ability to form DNA adducts, including N-(2'-deoxyguanosin-8-yl)-3-aminobenzanthrone (C8-dG-ABA). To investigate the molecular mechanism of C8-dG-ABA mutagenesis in human cells, we have replicated a plasmid containing a single ...

BACKGROUND In the U.S., tomatoes have become the most implicated vehicle for produce-associated Salmonellosis with 12 outbreaks since 1998. Although unconfirmed, trace backs suggest pre-harvest contamination with Salmonella enterica. Routes of tomato crop contamination by S. enterica in the absence of direct artificial inoculation have not been investigated. METHODOLOGY/PRINCIPAL FINDINGS Thi...

Rising temperatures and elevated atmospheric CO2 are two factors that simultaneously affect the dynamics of soil organic carbon (SOC). This study separately examines the effects arise from these two factors in Tai-Lake Paddy soils using DeNitrification–DeComposition (DNDC) model, with the currently most detailed soil database for the paddy region of China. The soil database is at a scale of 1:5...

The weak expansive soil subgrade of the railway in operation is prone to settlement a high-temperature climate, which results rapid deterioration geometric dimensions track, and affecting safety train operation. This paper uses Track Geometry Measurements (TGM) analyze characteristics track geometry parameters soil. Also establishes Settlement Prediction Model (SPM) identify time predict value ...

background : since the use of high concentrations of oxygen in infants may lead to chronic lung problems, using proper methods of care in infants under mechanical ventilation is one of the most important measures in nicu. this study aimed to investigate the effects of prone and supine positions on oxygenation (spo 2 ) in premature infants under mechanical ventilation and comparing infants’ oxyg...
