Background: The debate regarding use of WHO body mass index (BMI) cut-offs for the assessment of nutritional status continues in the scientific community. That is, BMI may not be a true reflection of body composition. Researchers have investigated BMI and percent body fat (%BF) as risk factors for some chronic diseases. Objectives: The current study sought to evaluate the use of BMI to assess %...

PURPOSE To study blood flow (BF) and metabolism in normal pancreas and in different pancreatic lesions. We then determined the effect of these biomarkers on outcome in patients with pancreatic cancer. EXPERIMENTAL DESIGN Oxygen-15-labeled water and fluorodeoxyglucose positron emission tomography/computed tomography scans were used in 26 patients with a suspicion of pancreatic cancer to measur...

Recently, a body adiposity index (BAI = (hip circumference)/((height)(1.5))-18) was developed and validated in adult populations. The aim of this study was to evaluate the performance of BAI in estimating percentage body fat (BF%) in a sample of Colombian collegiate young adults. The participants were comprised of 903 volunteers (52% females, mean age = 21.4 years ± 3.3). We used the Lin's conc...

We evaluated whether prior training would improve collateral blood flow (BF) to the calf muscles after acute-onset occlusion of the femoral artery. Exercise training was performed in the absence of any vascular occlusion. Adult male Sprague-Dawley rats ( approximately 325 g) were kept sedentary (n = 14), limited to cage activity, or exercise trained (n = 14) for 6 wk by treadmill running. Early...

The objective was to examine the effect of maternal nutrient restriction followed by realimentation during midgestation on uterine blood flow (BF). On Day 30 of pregnancy, lactating, multiparous Simmental beef cows were assigned randomly to treatments: control (CON; 100% National Research Council; n = 6) and nutrient restriction (RES; 60% of CON; n = 4) from Day 30 to 140 (period 1), and therea...

Klebsiella pneumoniae bacteremia biofilm traits and distribution characteristics have not been clarified. This study aimed to determine the prevalence and characteristics of K. pneumoniae bacteremia biofilm formation (BF) and to explore the virulence factors associated with K. pneumoniae BF. A total of 250 K. pneumoniae bacteremia isolates were collected from patients in Shenzhen and Shanghai, ...

Nitric oxide (NO) has been implicated in some of the central pathways engaged in the regulation of the sleep-wake cycle. The existence of nitric oxide synthase (NOS) in the cholinergic basal forebrain (BF) cells projecting to the cortex suggests a role for NO in the activation induced by the BF during arousal. We tested, in the anesthetized cat, the hypothesis that inhibition of NOS would decre...

In the paper, we proposed Dantzig selector based on $\ell_{1}-\alpha \ell_{2}$~$(0< \alpha \leq1)$ minimization for signal recovery. selector, constraint $\|{\bf A}^{\top}({\bf b}-{\bf A}{\bf x})\|_\infty \leq \eta$ some small constant $\eta>0$ means columns of ${\bf A}$ has very weakly correlated with error vector e}={\bf x}-{\bf b}$. First, recovery guarantees restricted isometry property (RI...
