The unsteady flows of an incompressible Oldroyd-B fluid between two infinite parallel plates are considered when the slippage between the plate and the fluid is valid. The relative velocity between the fluid and plate is assumed to be proportional to the shear rate at the plates. The flow is generated by moving one of the plates or application of the constant pressure gradient giving arise to t...

Seventy-five cases of total retinal detachment complicated by the more advanced grades (grades C and D) of proliferative vitreoretinopathy were treated with scleral buckling, vitrectomy, and air-fluid exchange. The overall reattachment rate was 56%, ranging from 100% in grade C-1 to 26% in grade D-3. The postoperative visual acuity was 6/120 or better in 48% of the 42 eyes in which the retina w...

The electro-osmotic peristaltic flow of a viscoelastic fluid through a cylindrical micro-channel is studied in this paper. The fractional Jeffreys constitutive model, including the relaxation time and retardation time, is utilized to describe the viscoelasticity of the fluid. Under the assumptions of long wavelength, low Reynolds number, and Debye-Hückel linearization, the analytical solutions ...

BACKGROUND Chemokines are involved in the pathogenesis of osteoarthritis (OA). CCL18, a member of the chemokines family, is observed in synovial fluid (SF) of OA patients. The aim of this study was to determine the association between CCL18 levels in serum and SF with radiographic knee OA. MATERIAL AND METHODS This study was conducted in a population of 308 patients with knee OA. The radiolog...

In this study, an analysis has been performed to study the problem of fully developed flow of a fourth grade nonNewtonian fluid between two stationary parallel plates in the presence of an externally applied uniform vertical magnetic field. Slip conditions is taken into account at the wall of the channel. Employing the similarity variables, the governing partial differential equations including...

UNLABELLED BACKGROUND Patients with severe sepsis or septic shock often exhibit significant cardiovascular dysfunction. We sought to determine whether severity of diastolic dysfunction assessed by transthoracic echocardiography (TTE) predicts 28-day mortality. METHODS In this prospective, observational study conducted in two intensive care units at a tertiary care hospital, 78 patients (ag...

A trypsin-induced hemagglutination (THA) assay was standardized to detect infectious bronchitis virus (IBV) in allantoic fluid (AF) of embryonated eggs. The test was used in 20 samples, each collected from 5 different layer farms suspected for IBV. Allantoic fluid from inoculated embryos was harvested and treated with reagent grade trypsin at the percentages of 0.25, 0.50, 1.0 and 2.0 for 30 mi...

PURPOSE Irrigation-induced increase in intrarenal pressure is of concern because it may cause infection due to increased pyelovenous and pyelolymphatic absorption. This study is the first to compare prospectively the absorbed fluid volumes during percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for stones larger than 2 cm. MATERIALS AND METHODS General anesthesia w...
