Postsystolic shortening and thickening of ischemic and postischemic myocardium are wellrecognized phenomena, but their significance is controversial. To discover whether postsystolic shortening and thickening might represent an active process and to establish their place as possible predictors of functional recovery during and after recovery from ischemia, we examined correlations in severely i...

BACKGROUND Although mucosal thickening is the most common radiographic finding observed regarding sinus pathology, the knowledge regarding its clinical significance on the outcomes of dental implants and grafting in the maxillary sinuses is still limited. We hypothesized that mucosal thickening would not alter the predictability for sinus floor augmentation and dental implant placement. The pur...

A novel shear thickening suspoemulsion is formulated and studied with a new rheo-microscope instrument. The experimental fluid system is comprised of a immiscible blend of Newtonian, low molecular weight poly(dimethylsiloxane) and a shear thickening suspension of colloidal silica in poly(ethylene glycol). The blend is studied as a function of composition where phase inversion is evident at low ...

Left ventricular (LV) thickening can be due to hypertrophy (concentric, asymmetric, eccentric) or remodelling (concentric or asymmetric). Pathological thickening may be caused by pressure overload, volume overload, infiltrative disorders, hypertrophic cardiomyopathy, athlete's heart or neoplastic infiltration. Magnetic resonance imaging (MRI) plays an important role in the comprehensive evaluat...

Shear thickening polishing technology using non-Newtonian fluids is a low-cost, low-damage method for the ultra-precision machining of complex curved surfaces. However, low efficiency and poorly controlled viscosity traditional shear significantly limit their practical applications. In this study, novel weak magnetic field-assisted fluid (WMFA-STPF) containing carbonyl iron particles, which uti...

conclusions the results of this meta-analysis show that colloid fluids can increase the successful resuscitation rate compared to crystalloid fluids especially in traumatic and hypovolemic patients.some of the colloids like albumin and dextran have a positive effect on reducing the mortality rate but others like hetastarch (hes) increase the mortality rate compared to normal saline (ns). result...

Immune-mediator CD40 ligand is expressed on a variety of cell types involved in the immune response and on the cells of the vascular system. Inhibition of CD40 signaling has been associated with reduction of experimental atherosclerosis and transplant-associated vasculopathy. Immune response also plays a cardinal role in intimal thickening after acute arterial-wall injury. After carotid artery ...

Suspensions of fumed silica in polypropylene glycol exhibit shear-thickening under steady shear and "strain-thickening" under oscillatory shear. Strain-thickening refers to a sharp increase in the complex viscosity eta* observed at critical combinations of strain-amplitude and frequency. Two regimes of strain-thickening behavior have been found: The first occurs at high critical strains and low...

The alternating current electroosmotic flow of a non-Newtonian power-law fluid is studied in a circular microchannel. A numerical method is employed to solve the non-linear Poisson-Boltzmann and the momentum equations. The main parameters which affect the flow field are the flow behavior index, the dimensionless zeta potential and the dimensionless frequency. At very low dimensionless frequenci...

background different methods are used for adequate fluid intake assessment, while there is no standard method for adequate fluid intake assessment. objectives the current pilot study aimed to evaluate the amount, type and frequency of fluids consumption to determine the correlation between three- and seven-day records. methods this pilot cross-sectional study was done on 30 adult subjects in ah...
