Pretransplant Midodrine Use-A Risk Factor for Graft Loss at 1 Year in Kidney Transplant Recipients?

Introduction: Hypotension is a frequent complication of patients who are on chronic maintenance hemodialysis. Midodrine is an alpha-1 adrenergic agonist used to treat patients on hemodialysis who have chronic hypotensiom. The aim of our study was to evaluate if patients who required midodrine for hypotension had inferior outcomes compared to those who did not require midodrine.

Developmental competence of ovum pick up derived Sahiwal cow oocytes in maturation media supplemented with cysteamine and melatonin.

Antioxidants, cysteamine and melatonin, have an important role on mitochondrial membrane potential (ΔΨM), in vitro nuclear maturation and developmental competence of oocytes. A comprehensive study was planned to investigate the effect of cysteamine 50 µM and melatonin 10 mol L as antioxidants on ΔΨM, in vitro nuclear maturation and developmental competence of ovum pick up (OPU) derived Sahiwal Cow oocytes. Culturable grade OPU derived Sahiwal oocytes were divided in to three in vitro maturation groups cultured in TCM-199 supplemented with cysteamine 50 µM, melatonin 10 mol L and TCM-199 alone, for assessing nuclear maturation by Lamin/ DAPI and developmental competence of oocytes.

Purcell enhanced laser action using a super-Tamm cavity mode.

Optical Tamm structures have potential for the development of optoelectronic devices, provided they overcome the challenge of low-quality factor of modes and inherent losses associated with plasmonic metal films. In this work, we present lasing in a super-Tamm structure consisting of a silver thin film deposited on a 4-(dicyanomethylene)-2-methyl-6-(4- dimethylaminostyryl)-H-pyran (DCM) dye-doped polyvinyl alcohol (PVA) spacer layer coated on a SiO/TiO one-dimensional photonic crystal with a lasing threshold of ∼0.07 mJ.
