This study reports a numerical approach for modeling the hydraulic resistance of a filter cake of deformable cells. First, a mechanical and osmotic model that describes the volume fraction of solids in a bed of yeast cells as a function of the compressive pressure it experiences is presented. The effects of pressure on the compressibility of yeast cells beds were further investigated both by fi...

If the halo of the lensing galaxy 0957+561 is made of massive compact objects (MACHOs), they must affect the lightcurves of the quasar images Q0957+561 A and B differently. We search for this microlensing effect in the double quasar by comparing monitoring data for the two images A and B – obtained with the 3.5m Apache Point Observatory from 1995 to 1998 – with intensive numerical simulations. ...

There are several reports of central pontine myelinolysis (CPM) in a setting of malnutrition, alcoholism, and chronic debilitating illness associated with electrolyte abnormalities, especially hyponatremia. The cause of myelinolysis is still under debate, and, although osmotic effects are thought to be responsible in most cases, alternative pathological factors should be considered [King et al....

Background: Risk of developing latent tuberculosis infection increases in medical students with their higher exposure to TB care facilities. Objective: To study the prevalence among attending professional degrees MBBS, BDS, MD, MS, MDS at King George’s Medical University, India. Methods: This was carried out Tuberculin skin testing and active cases were excluded. A standard dose 0.1?mL purified...

Primers were used to amplify a 561-bp region of the 16S rRNA gene of Ehrlichia phagocytophila from Ixodes scapularis ticks and small mammals collected in Rhode Island and Connecticut. DNA sequences for all 50 E. phagocytophila-positive samples collected from 1996 through 1998 in southwestern Connecticut were identical to the sequence reported for E. phagocytophila DNA from confirmed human cases...

BACKGROUND Obesity and type 2 diabetes mellitus (T2D) are known risk factors for colon cancer. Recent reports from a number of genome wide association studies (GWAS) have identified several single nucleotide polymorphisms (SNPs) associated with obesity and T2D. Here we tested the hypothesis that these SNPs may also be associated with risk of colon cancer. METHODS We genotyped nine SNPs report...
