Nutritional status of 50 newborns born to HIV infected mothers in a tertiary care hospital was compared with that of babies born to HIV seronegative mothers, as assessed by birthweight, mid arm circumference to head circumference ratio (MAC/HC), ponderal index (PI), and clinical assessment of nutritional status (CAN) score. The incidence of malnutrition in babies born to HIV infected mothers wa...
We report the detection of the elusive carbon-chain radical C 5 N in the dark cloud TMC1 and its tentative detection in the circumstellar envelope IRC+10216. C 5 N appears to be two orders of magnitude less abundant than the related molecule HC 5 N and much less abundant than expected from current gas phase chemistry models. In comparison the HC 3 N to C 3 N abundance ratio is of the order of 1...
Hepatocellular carcinoma (HC) is often difficult to distinguish from secondary liver neoplasia (SLN) by physical and imaging diagnostic procedures alone. To this aim we have extended and improved a laboratory approach based on a serum lactate dehydrogenase isoenzyme ratio (LD4:LD5) by adding the carcinoembryonic antigen: alpha-fetoprotein ratio, alkaline phosphatase, and serum iron concentratio...
Transient receptor potential vanilloid 4 (TRPV4) is a Ca2+-permeable nonselective cation channel and can be activated during ischemia/reperfusion (I/R). This study tested whether blockade of TRPV4 can alleviate myocardial I/R injury in mice. TRPV4 expression began to increase at 1 h, reached statistically at 4 h, and peaked at 24-72 h. Treatment with the selective TRPV4 antagonist HC-067047 or ...
This study evaluates the serum concentrations of rifampin (RMP), isoniazid (INH), and intestinal barrier function in patients with multidrug-resistant tuberculosis (MDR-TB), drug susceptible tuberculosis (DS-TB), and health volunteers (HC; controls). Peak serum concentrations of RMP were significantly lower in MDR-TB and DS-TB as compared with HC (odds ratio [OR] = 3.125, confidence interval [C...
BACKGROUND The main aim of this study was to evaluate the association between serum cholesterol level and body mass index (BMI) in northern Iran. METHODS This was a cross-sectional study carried out on the 1995 subjects (997 males and 998 females) aged 25-65 years that were selected using multistage cluster sampling method. Plasma cholesterol was measured in the morning after a 12-hour fastin...
Current technologies are fast approaching the capacity limit of single mode fibers (SMFs). Hollow-core photonic bandgap fibers (HC-PBGFs) are expected to provide attractive long-term solutions in terms of ultra-low fiber nonlinearities associated with the possibility of mode scaling, thus enabling mode division multiplexing (MDM). In this work, we demonstrate MDM over a HC-PBGF for the first ti...
In many industrial systems, design complexity is partly reduced by the use of non-preemptive message passing or execution. Doing so, context switch overheads are diminished and resource sharing mechanisms are simplified. However, in a mixedcriticality system, long blocking time caused by non-preemptive execution of a task which has lower priority than some other high criticality (HC) tasks migh...
This paper investigates the performance of U-type pulsejet engine whose overall length is approximately 160 cm. Gas dynamics, acoustics and chemical kinetics were modeled to gain an understanding of various physical phenomena affecting pulsejet operation, scalability, and efficiency. The pulsejet was run in valveless mode on LPG fuel. Pressure, temperature, thrust, specific impulse, and concent...
