BACKGROUND In Bihar, India, high maternal anemia prevalence and low iron and folic acid supplement (IFA) receipt and consumption have continued over time despite universal IFA distribution and counseling during pregnancy. PURPOSE To examine individual and facility-level determinants of IFA receipt and consumption among pregnant women in rural Bihar, India. METHODS Using District Level House...
The anticancer prodrug ifosfamide (IFA) contains a chiral phosphorous atom and is administered in the clinic as a racemic mixture of R-IFA and S-IFA. Hepatic cytochrome P450 (P450) enzymes exhibit enantioselective preferences in the metabolism of R-IFA and S-IFA; however, the impact of this selectivity on P450-dependent anticancer activity is not known. Presently, the metabolism and cytotoxicit...
OBJECTIVE The prevalence of maternal anaemia remains unacceptably high in developing countries. At the same time, the percentage of women who consume one or more Fe+folic acid (IFA) tablets during pregnancy remains persistently low. The objective of the present study was to identify where, within antenatal care (ANC) programmes, pregnant women falter in obtaining and consuming an ideal minimum ...
Immunofluorescence assay (IFA) is one of the most frequently used methods in the biological sciences and clinic diagnosis, but it is expensive and time-consuming. To overcome these limitations, we developed a faster and more cost-effective IFA (f-IFA) by modifying the standard IFA, and applied this method to track the progression of human cytomegalovirus (HCMV) infection in different cells. The...
Human monocytic ehrlichiosis is an emerging infectious disease caused by Ehrlichia chaffeensis, a gram-negative obligatory intracellular bacterium closely related to E. canis. The immunoreactive recombinant fusion proteins rP28 and rP30 have become available after cloning and expressing of the 28- and 30-kDa major outer membrane protein genes of E. chaffeensis and E. canis, respectively. Wester...
Acute human parvovirus B19 infection is followed by an antibody response to the structural proteins of the viral capsid (VP1 and VP2). We used 80 sera collected from 58 erythema infectiosum and 6 transient aplastic crisis patients to test IgM and IgG antibodies against these two proteins in an immunofluorescence assay (IFA) using Sf9 cells infected with recombinant baculovirus expressing either...
The diagnosis of melioidosis depends on the culture of Burkholderia pseudomallei, which takes at least 48 hours. We used a polyclonal-FITC-based immunofluorescence microscopic assay (Pab-IFA) on clinical samples to provide a rapid presumptive diagnosis. This has limitations including photobleaching and batch-to-batch variability. This study evaluated an IFA based on a monoclonal antibody specif...
چکیده مقدمه: سندرم لارو مهاجر احشائی(VLM) یک بیماری زئونوز بوده که در اثر استقرار لاروهای توکسوکارا کانیس یا توکسوکارا کتی در بافتها یا اندامها ایجاد می شود. این مطالعه با هدف ارزیابی و مقایسه روش های سرولوژی IFA و ELISA در تشخیص سندرم لارو مهاجر احشائی به دنبال یک بررسی سرواپیدمیولوژیک در شهرستان تبریز انجام گرفته است. مواد و روش ها: در این مطالعه توصیفی – تحلیلی 558 نفر از افراد بین 20-2 سال ...
Screening of blood and blood products for human immunodeficiency virus (HIV) is routinely performed using the enzyme-linked immunosorbent assay (ELISA), and the results confirmed by western blot (WB). In an effort to identify alternative techniques, two locally prepared test kits were evaluated to determine the performance in comparison to commercial kits. These diagnostic kits were indirect im...
Laboratory diagnosis of human ehrlichioses is routinely made by an indirect immunofluorescence assay (IFA) using cultured ehrlichia-infected whole cells as antigen. Concern has been raised that incorrect diagnoses of human monocytic ehrlichiosis (HME) or human granulocytic ehrlichiosis (HGE) may be made on the basis of serologic cross-reactivity between Ehrlichia chaffeensis and the agent of HG...
