introduction: the aim of this study was to evaluate the relation between protamine deficiency assessed by cma3 and protamine 1/ protamine 2 (p1/p2) ratio. material and methods: this study was carried out on 71 patients referring to isfahan fertility and infertility center. semen analysis was assessed according to who criteria. cma3 staining was use to determine protamine deficiency. p1/p2 ratio...

Abstract Although it is well established that nitrogen (N) deficiency induces leaf senescence, the molecular mechanism of N deficiency-induced senescence remains largely unknown. Here, we show an abscisic acid (ABA)-responsive NAC transcription factor (TF) involved in senescence. The overexpression MdNAC4 led to increased ABA levels apple calli by directly activating biosynthesis gene MdNCED2 ....

a nine-month old male child presented with low-grade fever, loose stools and facial puffiness. clinically patient was otherwise normal except for a firm liver on palpation. the laboratory tests revealed hypoproteinemia (both albumin and globulin) and iron deficiency anemia. differential diagnosis considered were: 1. nephrotic syndrome, 2. cystic fibrosis (in view of recurrent diarrhea and respi...

Protein C (PC) is an essential vitamin K-dependent protein that regulates thrombosis and hemostasis in the body. A mutation PROC gene on chromosome 2q14.3 results PC deficiency. The clinical presentation of deficiency can vary, ranging from a single vein to disseminated intravascular coagulation, purpura fulminans, or even life-threatening complications such as sepsis. Here, we present case 37-...

iron deficiency in soil reduces the quality of durum wheat leading to fe deficiency in human. thus, this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g l-1), iron chelate (edta), (4 and 8 g l-1), iron sulfate (4 and 8 g l-1), and the control on grain yield and quality, yield components, chlorophyll and carotenoids contents, peroxidase (pox), catalase (ca...
