To measure the prevalence of cytomegalovirus (CMV) infection in ectopic pregnancy (EP) and its effect on the expression of inducible and endothelial nitric oxide synthases (iNOS, eNOS) by Fallopian tubes (FT) bearing an EP. This was a prospective case–control study. Blood and tubal samples were collected from 84 Eps and 51 controls (20 total abdominal(More)
This was a prospective case-control study that measured the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Mycoplasma genitalium (MG) by an IVD CE multiplex PCR kit in fresh Fallopian tubes (FT) obtained from 96 ectopic pregnancies (EP) and 61 controls in the midluteal phase of the cycle. We later measured the expression profile of(More)
Dengue viruses (DENVs) are mosquito-borne viruses which can cause disease ranging from mild fever to severe dengue infection. These viruses are endemic in several tropical and subtropical regions. Multiple outbreaks of DENV serotypes 1, 2 and 3 (DENV-1, DENV-2 and DENV-3) have been reported from the western region in Saudi Arabia since 1994. Strains from at(More)
AIMS To measure the expression of activin βA-subunit, activin IIA and IIB receptors, Smad4, Smad7, and follistatin in the liver and the liver and serum concentrations of mature activin-A and follistatin in normal rat following treatment with pegylated interferon-α (Peg-INF-α) and ribavirin (RBV). MATERIALS AND METHODS 40 male Wistar rats were divided(More)
Pegylated-interferon-α based therapy for the treatment of chronic hepatitis C (CHC) is considered suboptimal as not all patients respond to the treatment and it is associated with several side effects that could lead to dose reduction and/or termination of therapy. The currently used markers to monitor the response to treatment are based on viral kinetics(More)
Chronic hepatitis C (CHC) is one of the most common causes of liver diseases worldwide, affecting 3% of the world population and 3 to 4 million people acquire new infection annually. Despite the recent introduction of novel antiviral drugs for the treatment of CHC, these drugs are expensive and the access to them is not an option for many patients. Hence,(More)
BACKGROUND Ectopic pregnancy (EP) is associated with maternal morbidity and occasionally mortality during the first trimester. A history of sexually transmitted infection (STI) and pelvic inflammatory disease have been implicated as major risk factors for EP. Our aim was to measure the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae,(More)
INTRODUCTION The World Health Organization's persistent reporting of global outbreaks of influenza A viruses, including the 2009 pandemic swine A H1N1 strain (H1N1pdm09), justified the targeted surveillance of pilgrims during their annual congregation that pools more than two million people from around 165 nations in a confined area of Makkah city in the(More)
Aims. To measure the effect of pegylated interferon- α therapy on serum activin-A, activin-B, and follistatin and their correlation with viral load and liver fibrosis in chronic hepatitis C (CHC). Methods. This study was cross-sectional and sera were collected from 165 participants classified into 7 groups: 40 healthy negative control, 33 treatment naïve(More)
