It is not clear if HIV-1 variants lose the ability to prime naïve CD8+ cytotoxic T lymphocytes (CTL) during progressive, untreated infection. Answering this question is important for developing immunotherapeutic approaches for enhanced control of residual HIV-1 infection in persons on combination antiretroviral therapy (cART). We therefore conducted a comprehensive longitudinal analysis of viral evolution and its impact on primary Read More

Background: Anemia of chronic disease (ACD) is highly prevalent among subjects with chronic kidney disease (CKD), rheumatoid arthritis, diabetes mellitus, and cancer as well as in elderly subjects. ACD is also highly associated with infections, severe trauma and critical illness. Anemia of chronic disease is immune driven and is associated with decreased quality of life, and increased mortality. Iron is an essential nutrient for erythr Read More

Introduction: Similar to many countries in the world, breast cancer is the most common cancer among women in the State of Qatar and the incidence rate is rising. Previous findings indicate women in Qatar are often diagnosed with breast cancer at advanced stages and their awareness of breast cancer screening (BCS) services and participation rates in screening activities are low. Previous studies indicate the need to un Read More

Background and objectives: Cerebral auto-regulation is an intrinsic protective mechanism guaranteeing hemodynamic integrity of cerebral circulation. It modulates cerebral blood flow (CBF) in order to meet regional perfusion demands despite variations in arterial blood pressure. Impaired cerebral auto-regulation is associated with poor functional and prognostic outcomes in patients with ischemic stroke. The aims Read More

Blood stream infections due to Candida species cause significant morbidity and mortality in health care settings. This surveillance analysis describes the epidemiology, trend in species distribution and outcomes of candidemia in patients at Hamad hospital, Doha, Qatar. From January 2004 to December 2010, a total of 187 patients with 201 episodes of candidemia were identified. C. albicans was the most common species isol Read More

Background Osteoporosis is a common skeletal disorder characterized by low bone mass and microarchetectual deterioration of bone tissue with increased susceptibility to fractures. Osteoporosis is considered a multifactorial polygenic disease. The prevalence of postmenopausal osteoporosis in Palestine, based on of BMD at femoral neck, total hip and spine was 24%, 14% and 29.7% respectively. Previous studies on the effect Read More

Absorbed Dose Distributions In Lineal Energy For Neutrons And Gamma Rays Were Measured Using Both A Tissue-Equivalent Walled Counter (Tepc) And A Graphite-Walled Low Pressure Proportional Counter (Gpc) In The Am-Be Neutron Source Facility At Uoit. A Series Of Measurements Were Performed With The Counters Filled With Propane-Based Te Gas (55.1% C3H8, 39.5% Co2 And 5.4% N2) At Operating Gas Pressures Corr Read More

Monitoring of respiratory rate and amplitudes of a human being has important medical applications such as in health monitoring as well as in diagnosis of respiratory illnesses and disorders such as the sleep apnea disorder. Currently used techniques for respiratory monitoring require patients to wear sensors and electrodes across the chest to measure the respiratory effort. Such techniques not only cause discomfort t Read More

Background: Children with cancer who are treated with intensive myelosuppressive chemotherapy or radiation therapy and develop neutropenia are at risk of developing life-threatening infections. In adult cancer patients with febrile neutropenia, some evidence suggests that there is no difference in efficacy between monotherapy and combination gram negative empiric antibiotic regimens. Outcomes of these different a Read More

Background Many diabetes patients choose to participate in the Ramadan fast despite medical and religious advice to the contrary. Pharmacists, especially in ambulatory care, are considered the most easily and readily accessible health care providers whose guidance can help ensure safe fasting for these patients. Objective The aim of this novel study is to describe Qatar pharmacists' current practice, knowledge, and attitu Read More

A Novel Bace-1 Inhibitor, F70Hab16 Reduces Oxidative Stress In Brain Tissues Of Scopolamine-Induced Amnesia In Mice

Background: patients with type 2 diabetes (T2DM) are subjected to reduction in the quality and oxidative capacity of muscles. The effect of duration of diabetes on the muscle endurance response is not clear and strength as well .The aim of this study was the assessment of strength and endurance of knee extensor and flexor in the patients with T2DM<10 and T2DM>10 years in comparison with age, sex, BMI, ABI and PAI Read More

Development, Implementation, and Evaluation of a Novel Medication Safety Health Promotion Program for Schoolchildren in Qatar

Associations of single nucleotide polymorphisms(rs2383207) on chromosome 9p21 with coronary artery diseases in Qatar

Assessment of Parylene C Thin Films for Heart Valve Tissue Engineering

The idea of deploying multiple wireless sensors around the human body to enable ubiquitous healthcare by measuring continuously all the physiological data of interest has received considerable attention. Ultra-wideband (UWB) is a promising communication technology for short-range communication scenarios like body-centric wireless network (BCWN) (i.e, in the area of medical healthcare). UWB is characterized by lo Read More

Whole genome sequencing provides a rich and unprecedented collection of the existing genetic variation in a genome. The development of next generation sequencing (NGS) technologies has enabled a rapid and relatively inexpensive method for whole genome sequencing. The current archive of genetic variations in the horse is mostly based on the Thoroughbred mare used to generate the reference sequence (EquCab Read More
