asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
Four Bangladeshi medicinal plants Withania somnifera, Terminalia arjuna, Moringa olifera and Asparagus racemosus have been investigated for their in vitro thrombolytic and membrane stabilizing. Among the four plants, the methanol extract of W. somnifera exhibited highest thrombolytic activity with clot lysis value of 36.50%. Standard streptokinase and water were used as positive and negative co...
Two Bangladeshi medicinal plants Tridax procumbens and Vernonia cinerea have been investigated for their in vitro thrombolytic, membrane stabilizing and cytotoxic properties. The total phenolic content was also determined and expressed in gallic acid equivalent. Among the two plants, the methanol extract of T. procumbens exhibited highest thrombolytic activity with clot lysis value of 21.15%. S...
The endoplasmic reticulum (ER) consists of the nuclear envelope and a peripheral network of tubules and membrane sheets. The tubules are shaped by the curvature-stabilizing proteins reticulons and DP1/Yop1p, but how the sheets are formed is unclear. Here, we identify several sheet-enriched membrane proteins in the mammalian ER, including proteins that translocate and modify newly synthesized po...
The function of membrane proteins is best understood if their structure in the lipid membrane is known. Here, we determined the structure of the mouse serotonin 5-HT3 receptor inserted in lipid bilayers to a resolution of 12 Å without stabilizing antibodies by cryo electron tomography and subtomogram averaging. The reconstruction reveals protein secondary structure elements in the transmembrane...
