In this study, a simple and reliable square wave voltammetric (SWV) method was developed and validated for determination of diclofenac in pharmaceutical preparations and human serum. The proposed method was based on electrooxidation of diclofenac at platinum electrode in 0.1 M TBAClO4/acetonitrile solution. The well-defined two oxidation peaks were observed at 0.87 and 1.27 V, respectively. Cal...

background: considering the effect of preterm delivery in morbidity and mortality of newborns, its precaution and prevention is so important. objective: to investigate the association between second trimester maternal serum biomarkers (human chorionic gonadotropin, alpha-fetoprotein, non-conjugated estrogen, inhibin a) and pre-term delivery. materials and methods: this is a historical cohort st...

BACKGROUND Selenoprotein S (SelS) is a transmembrane protein that is expressed in the liver, skeletal muscle, adipose tissue, pancreatic islets, kidney, and blood vessels. In addition to its transmembrane localization, SelS is also secreted from hepatoma HepG2 cells (but not L6 skeletal muscle cells, 3T3-L1 adipocytes, Min6 pancreatic β cells and human embryonic kidney 293 cells) and has been d...

Template-electrodeposited polymer/Pt microtube engines display efficient propulsion in a wide range of real-life samples ranging from seawater to human serum. Remarkably high speeds are observed in fuel-enhanced raw serum, apple juice, seawater, lake and river water samples. Our results indicate that polymer-based microengines hold considerable promise for diverse practical applications and tha...

The functional activities of serum samples from human infants immunized with a glycoconjugate vaccine for Neisseria meningitidis serogroup C were assessed in a complement-mediated antibody-dependent serum bactericidal assay (SBA) and in a neonate rat model of protection from bacteremia. Selective serum samples from individual human infants were combined to make a panel of 11 serum pools to obta...

Objective(s):The present study reports the development and validation of a sensitive and rapid extraction method beside high performance liquid chromatographic method for the determination of crocetin in human serum. Materials and Methods:The HPLC method was carried out by using a C18 reversed-phase column and a mobile phase composed of methanol/water/acetic acid (85:14.5:0.5 v/v/v) at the flow...

In present pilot study aimed to estimate, presence of Mycobacterium avium subspecies paratuberculosis (MAP) antibodies in the human serum samples originating from North India using "Indigenous absorbed ELISA kit" (ELISA kit). The phase I, "ELISA kit" was optimized using protoplasmic antigen from native isolate of MAP "Indian Bison type" recovered from the biopsies of Crohn's disease patients. T...

Recombinant Toxoplasma gondii small heat shock protein HSP20, surface antigen SAG1 and dense granule GRA7 were analyzed by IgG-ELISA with serum samples of Toxoplasma infected humans grouped as I (IgG+, IgM+), II (IgG+, IgM-) and III (IgG-, IgM-). rHSP20 reacted against 80% and 62.5% of serum samples from groups I and II, respectively. rSAG1 was recognized by 85% of the samples from group I and ...
