Aquaporin-0 (AQP0) is a lens-specific water channel that also forms membrane junctions. Reconstitution of AQP0 with dimyristoyl phosphatidylcholine (DMPC) and E. coli polar lipids (EPL) yielded well-ordered, double-layered two-dimensional (2D) crystals that allowed electron crystallographic structure determination of the AQP0-mediated membrane junction. The interacting tetramers in the two crys...

Whether or not the use of hormonal contraception affects risk of HIV acquisition is an important question for public health. We did a systematic review, searching PubMed and Embase, aiming to explore the possibility of an association between various forms of hormonal contraception and risk of HIV acquisition. We identified 20 relevant prospective studies, eight of which met our minimum quality ...

aqueous polyurethane dispersions (puds) have recently emerged as important alternatives to their solvent-based counterparts for various applications due to increasing health and environmental awareness (green chemistry). anionic polyester-polyurethane dispersions were synthesized by three steps. in the first step, macromonomer diisocyanate having carboxylic acid was prepared by isophorone diiso...

Women are always afraid about weight and some of them report weight changes after started a hormonal contraceptive. A recent Cochrane’s review affirmed that it is a patient misperceived perception. The review analyzed effects of progestogen-only contraceptive methods (implants, LNG-IUS, oral progesteroneonly and depot medroxyprogesterone acetate-DMPA) on weight and found limited scientific evid...
