the purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive propranolol hydrochloride microspheres for its potential use in the treatment of hypertension, myocardial infraction and cardiac arrhythmias. propranolol hydrochloride mucoadhesive microspheres, containing carbopol-934p as mucoadhesive polymer and ethyl cellulose as carrier ...

In this study, the removal of Malachite Green dye in synthetically prepared aqueous solution by electrocoagulation process was investigated. initial concentration, electrolyte amount, mixing speed, current density, electrolysis time, pH value, and distance between electrodes parameters that affect efficiency method were As a result optimum found as an concentration 200 mg/L, amount 150 stirring...

Large-scale chaotic stirring stretches tracer contours into filaments containing fine spatial scales until smallscale diffusive processes dissipate tracer variance. Quantification of tracer transport in such circumstances is possible through the use of Nakamura’s ‘‘effective diffusivity’’ diagnostics, which make clear the controlling role of stirring, rather than small-scale dissipation, in lar...

The hybridoma 192 was used to produce a monoclonal antibody (MAb) against 17-hydroxyprogesterone (17-OHP), for possible use in screening for congenital adrenal hyperplasia (CAH). The factors influencing the MAb production were screened and optimized in a 2 L stirred bioreactor. The production was then scaled up to a 20 L bioreactor. All of the screened factors (aeration rate, stirring speed, di...

1. Filters comprising multiple layers of rabbit renal tubular basement membrane were constructed with conventional pressure filtration chambers. The effects of concentration-polarization on the behaviour of these filters was assessed by studying the filtration of proteins and of serum under turbulent (stirred) and unstirred conditions. 2. With stirring bovine serum albumin was effectively rejec...
