introduction: cesarean surgical site infection (ssi) occurs in 3% to 17% of patients who undergo cesarean delivery. ssis increase postcesarean maternal morbidity and health costs and cause longer hospital stays. therefore, we designed a study to assess the effects of normal saline and cefazolin irrigation on the incidence of ssis. methods: in this study, 200 participants were divided into 3 gro...

OBJECTIVE To estimate if membrane sweeping increases the rate of prelabor rupture of membranes. METHODS This randomized trial of term, uncomplicated pregnancies included 300 patients. Patients were randomly assigned into sweep or no-sweep groups, with patients and delivering providers blinded to group allocation. Only the examining provider in the clinic was unblinded to group allocation. Mem...

Escape from the host erythrocyte by the invasive stage of the malaria parasite Plasmodium falciparum is a fundamental step in the pathogenesis of malaria of which little is known. Upon merozoite invasion of the host cell, the parasite becomes enclosed within a parasitophorous vacuole, the compartment in which the parasite undergoes growth followed by asexual division to produce 16-32 daughter m...

Three opposing pathways are proposed for the release of malaria parasites from infected erythrocytes: coordinated rupture of the two membranes surrounding mature parasites; fusion of erythrocyte and parasitophorus vacuolar membranes (PVM); and liberation of parasites enclosed within the vacuole from the erythrocyte followed by PVM disintegration. Rupture by cell swelling should yield erythrocyt...

cigarette smoking is one of the main risk factors for premature human death associated to a variety of respiratory and vascular diseases, and cancer due to containing hundreds of toxicants. rat mitochondria were obtained by differential ultracentrifugation and incubated with different concentrations (1, 10 and 100%) of standardized cigarette smoke extract (cse). our results showed that cigarett...

BACKGROUND AND OBJECTIVES The aim of this study was to report preliminary data on pregnancy outcomes after myomectomy with placement of an expanded polytetrafluoroethylene adhesion barrier membrane. METHODS In this retrospective case series, 68 women who underwent myomectomy with expanded polytetrafluoroethylene membrane placement between January 1, 2003, and December 31, 2009, were identifie...

The authors retrospectively evaluated maternal and fetal outcomes of 73 consecutive singleton pregnancies complicated by preterm premature rupture of amniotic membranes. When preterm labor occurred and fetuses were at a viable gestational age, pregnant patients were managed aggressively with tocolytic therapy, antenatal corticosteroid injections, and antenatal fetal testing. The mean gestationa...
