results the optimal conditions were considered to perform elisa. comparison between results obtained from optimized elisa kit and commercial elisa kit showed a good agreement. background haemophilus influenzae type b (hib) infection has high morbidity and mortality rate, especially in children under 5 years of age. enzyme-linked immunosorbent assay (elisa) technique is the most used method to d...

background: diarrhea, caused by enteroaggregative escherichia coli (eaec), is an important cause of illness and death. numerous virulent factors have been described in eaec. however, their prevalence was highly variable among eaecs of distinct geographic locations. studies have shown that dispersin (antiaggregation protein, aap) is one of the important and abundant virulent factors in eaec. in ...

introduction: periodontitis is a multi-factorial inflammatory disease of periodontium. a precise mechanism in which smoking affects periodontium is not accurately understood. this study was planned to survey salivary osteocalcin (oc) level among smokers with chronic periodontitis and its comparison to non-smoker patients which may help achieve a better understanding of mechanisms being involved...

BACKGROUND Biomarkers of exposure to Plasmodium falciparum would be a useful tool for the assessment of malaria burden and analysis of intervention and epidemiological studies. Antibodies to pre-erythrocytic antigens represent potential surrogates of exposure. METHODS AND FINDINGS In an outbreak cohort of U.S. Marines deployed to Liberia, we modeled pre- and post-deployment IgG against P. fal...

Study comprised one thousand suspected individuals (884 females and 116 males) reported for the screening of thyroid disorders of different age and sex from Kangra district of Himachal Pradesh. History, sign and symptoms of individuals were recorded and total triiodothyronine (TT3), thyroxine (TT4) and thyroid stimulating hormone (TSH) levels were estimated by using micro well Enzyme Linked Imm...

Insulin loaded hydrophobic nanoparticles were prepared by solvent diffusion followed by lyophilization. Nanoparticles were characterized for mean size by dynamic laser scattering and for shape by scanning electron microscopy. Insulin encapsulation efficiency, in vitro stability of nanoparticles in presence of proteolytic enzymes and in vitro release were determined by high pressure liquid chrom...

Allergen-specific immunotherapy (SIT) reduces allergen specific IgE (sIgE) levels and achieves clinical and immunological tolerance by modulating innate and adaptive immunological responses. Increased temperature and CO2 concentrations caused by climate changes contribute to an increase of pollen count and allergenicity that influences clinical SIT outcomes. In this study, we investigated the c...

We evaluated the prevalence of antibodies to human papillomavirus (HPV) type 16 in a representative sample of children 6-11 years of age in the United States. Serum samples and questionnaire data were collected between 1991 and 1994, for the National Health and Nutrition Examination Survey III. HPV-16-specific immunoglobulin G antibodies were detected by an HPV-16 L1 virus-like particle-based e...

OBJECTIVE To elucidate the prevalence of congenital toxoplasmosis in Turkey. METHODS This study was conducted in the Department of Parasitology, Faculty of Medicine, Ege University, Izmir, Turkey during the period of 2006 and 2007. Venous blood before delivery and cord blood during delivery were collected from 138 women, and we observed the presence of immunoglobulin (Ig)G and IgM antibodies ...

BACKGROUND Adiponectin is an adipocytokine secreted from white adipose tissue. Serum level of adiponectin has been shown to be reduced in several disease states like obesity and diabetes. Hypoadiponectinemia has also been included in the list of newer risk factors for Coronary Artery Disease (CAD). METHODS In this analytical cross-sectional study serum adiponectin level was measured by Enzyme...
