Development of a new, highly sensitive zona pellucida binding assay using a bioluminescence-enhanced detection system
To date, two different zona binding assays have been described in the literature. Both assays, however, require a large quantity of human zonae which vary immensely in quality. Furthermore, an inverted microscope with ...
Characterization and phylogenetic analysis of South African HIV-1 subtype C accessory genes
To acquire new knowledge about the genetic diversity and potential impact on vaccine strategies of HIV-1 subtype C in South Africa, we have characterized the vif, vpr, and vpu genes of 15 isolates. Phylogenetic analysis ...
Combined heterozygosity for methylenetetrahydrofolate reductase (MTHFR) mutations C677T and A1298C is associated with abruptio placentae but not with intrauterine growth restrictionCombined heterozygosity for methylenetetrahydrofolate reductase (MTHFR) mutations C677T and A1298C is associated with abruptio placentae but not with intrauterine growth restriction
Objective: This study was undertaken to investigate the involvement of MTHFR gene mutations C677T and A1298C implicated in vascular disease, in patients with abruptio placentae and intrauterine growth restriction (IUGR). ...
High-dose antithrombin III in severe sepsis: A randomized controlled trial
Context: Activation of the coagulation system and depletion of endogenous anticoagulants are frequently found in patients with severe sepsis and septic shock. Diffuse microthrombus formation may induce organ dysfunction ...
Postnatal zidovudine in prevention of vertical HIV-1 transmission in a service setting
We sought to determine the efficacy of a 4-6 week course of zidovudine (ZDV) in a group of infants exposed to HIV-1. A retrospective chart review was conducted on HIV-1-exposed neonates identified from February 1998 to ...
Citalopram 20 mg, 40 mg and 60 mg are all effective and well tolerated compared with placebo in obsessive-compulsive disorder
Serotonin reuptake inhibitors appear to be uniquely effective treatments for obsessive-compulsive disorder (OCD). This double-blind, placebo-controlled study was the first trial to assess the efficacy of the most selective ...
Clinicopathological features of Meckel's diverticula in 32 patients, with emphasis on the presence of Helicobacter pylori
Meckel's diverticula (MD) with areas of gastric heterotopia (metaplasia) are more likely to become symptomatic than those that contain mucosa of purely an intestinal type. Helicobacter pylori has been associated with the ...
