INTRODUCTION The discovery of a cure for diabetes is a dream of many medical researchers. The transplantation of Langerhans islets is a potential treatment of choice for patients with type 1 diabetes as a source of endogenous insulin for the recipient. OBJECTIVES The aim of the experiment was to transplant Langerhans islets without immunosuppression. To protect the grafts against transplant r...

the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...

The article discusses the relevance and features of use reverse osmosis when adjusting physico-chemical composition aqueous solutions especially drinking water. main element any plant is a semi-permeable membrane, which polymer composite material uneven density. It has been shown that membranes must meet certain requirements, are selectivity to components removed at this functional stage, compl...

Microporous osmotic tablet of diltiazem hydrochloride was developed for colon targeting. These prepared microporous osmotic pump tablet did not require laser drilling to deliver the drug to the specific site of action. The tablets were prepared by wet granulation method. The prepared tablets were coated with microporous semipermeable membrane and enteric polymer using conventional pan coating p...

Seawater desalination plants discharge brine which is at higher salt concentration than the supplied seawater feed. Diluting this brine by mixing it with the lower concentration feed (seawater) will reduce the environmental hazards associated with the high salt concentration of the disposed brine. Energy can be generated from the dilution process in which two streams of different salt concentra...

Species can be defined as populations that are diagnosably distinct, reproductively isolated, cohesive, or exclusive groups of organisms. Boundaries between species in sympatry are maintained by intrinsic barriers to gene exchange; these boundaries may not be uniform in space, in time, or across the genome. Here, we explore the nature of the species boundary, defined as the phenotypes/genes/gen...
