Abstract Background Patellofemoral complications are one of the major issues after total knee arthroplasty (TKA). Excessive patellofemoral joint pressure is associated with TKA surgery, and amount patellar osteotomy has a direct effect on pressure. The purpose this study was to evaluate influence patella thickness in TKA. Methods Five freshly frozen cadavers were operated custom-made Stryker po...

The cardiovascular effects of i.v. cimetidine 200 mg or ranitidine 50 mg were investigated in a double-blind cross-over study of 20 critically ill patients in an intensive therapy unit. Both agents caused transient decreases in mean arterial pressure and systemic vascular resistance, although there was no significant change in heart rate, cardiac output, central venous pressure, pulmonary arter...

The effects of electroacupuncture (EA) on intraocular pressure (IOP) and hemodynamic parameters were evaluated in isoflurane anesthetized 10 (5 males, 5 females) normal mongrel dogs (8.1-9.8 kg, 6-8 years old). After determination of baseline IOP and hemodynamic parameters (cardiac index, systolic arterial pressure, diastolic arterial pressure, heart rate and systemic vascular resistance index)...

This paper shows that the theory describing gas diffusion with no consideration of total pressure leads to an underestimation water vapor diffusive permeability. experimental method, called cup can be considered as one most popular tests in domain heat and mass transfer for building applications. Thus, it is likely permeability defined current materials underestimated. Thanks approach proposed ...

The hypothesis tested was that there are significant transient changes in the cardiovascular variables after rapid onset and release of mild lower body negative pressure (LBNP, -20 mmHg), even in experimental situations where there is no detectable change in steady-state values. Twelve subjects participated in the study. Heart rate, stroke volume (SV), cardiac output, mean arterial pressure (MA...
