Voltage-dependent K(+) (Kv) channels require lipid phosphates for functioning. The S4 helix, which carries the gating charges in the voltage-sensing domain (VSD), inserts into membranes while being stabilized by a protein-lipid interface in which lipid phosphates play an essential role. To examine the physical basis of the protein-lipid interface in the absence of lipid phosphates, we performed...

___________________________________________________________________________________________ Abstract Phosphates are inorganic compounds, based on the element phosphorus, combined with oxygen to form phosphates, the form in which phosphorus is present in nature. Phosphates are essential for plant growth, crops, and human health. Phosphates have been used in processing and preservation of fruits ...

Phosphates offer a range of possibilities when used in meat and poultry productions. Food grade phosphates are used in meat products for several reasons such as changing and/or stabilizing of pHvalue, increasing water holding capacity in order to lead to higher yields, decreasing losses of weight in cooking, improving texture and sensory properties (tenderness, juiciness, color and flavor), ext...

Enzymes that are capable of hydrolyzing ribonucleoside 2’, 3’cyclic phosphates but that do not attack intemucleotide bonds are available from various sources (1). Several of these enzymes convert ribonucleoside 2’,3’-cyclic phosphates to the corresponding ribonucleoside 2’-phosphates. The first die&erase of this type was studied in calf spleen by Whitfeld, Heppel, and Markham (2). Davis and All...

Background: Halothane is the routine used inhalation anesthetic drug in the world but at present, there is an increasing interest for using intravenous anesthetics like propofol. The purpose of this study was to compare these anesthetic effects on hepatic enzymes.Methods: From 2006 to 2007, this study was performed on fifty eight patients classified in class I of American Society of Anesthetics...

Introduction: The effect of fluid and food restrictions on biochemical substances relating to the renal and bone function of pregnant women is not well defined. The purpose of this study is to evaluate the effects of fluid and food restriction on the following substances in pregnant fasting women during Ramadan: blood urea nitrogen (BUN), creatinine (Cr), calcium (Ca), phosphorus (P), and alkal...

Abstract Background The aim of the present study was to determine the endocrine dysfunction in patients with major thalassemia, who receive hyper transfusion. Materials and Methods This cross sectional study was performed during one year, which included 65 major thalassemia patients (31 females and 34 males), aged between 14 month to 27 years old (median 10,3). Growth assessment was measur...

Phosphate recovery from different second streams using electrodialysis (ED) is a promising step to nutrients circular economy. However, the relatively low ED performance hinders widespread adoption of this environmentally sound method. The formation “bonded species” between phosphates and weakly basic fixed groups (primary secondary amines) anion exchange membrane can be cause decrease in curre...
