—In this paper, a transmit antenna selection scheme, which is based on shadowing side information, is investigated. In this scheme, the selected single transmit antenna provides the highest shadowing coefficient between transmitter and receiver. By the proposed technique, the frequency of the usage of the feedback channel from the receiver to the(More)
BACKGROUND Chemokines and their receptors play important roles in host defense, organogenesis, hematopoiesis, and neuronal communication. Forty-two chemokines and 19 cognate receptors have been found in the human genome. Prior to this report, only 11 chicken chemokines and 7 receptors had been reported. The objectives of this study were to systematically(More)
OBJECTIVE To investigate the psychometric properties of the Rivermead Motor Assessment by Rasch analysis and conventional statistics to improve its clinical utility. METHODS A total of 107 patients after stroke were evaluated using the Rivermead Motor Assessment and Functional Independence Measure (FIM). Scaling properties were assessed using Mokken(More)
BACKGROUND We investigated the relationship between peripheral neuropathy and parameters of arterial stiffness and carotid intima media thickness (CIMT) in patients with type 2 diabetes mellitus (T2DM). MATERIAL AND METHODS The study included 161 patients (80 females and 81 males), 69 of whom had peripheral neuropathy. All patients underwent 24-h blood(More)
BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation that correlates with cardiac events. This study assessed the association between NLR and the presence of chronic coronary total occlusion (CTO). METHODS The study population included 225 patients, a control group (n = 75), a coronary artery disease group (n = 75), and a(More)
Lung cancer (LC) and colorectal cancer (CRC) are the first and second deadliest types of cancer worldwide. EGFR-based therapy has been used in the treatment of these cancers with variable success. Presence of mutations in the KRAS driver oncogene, possibly induced by environmental factors such as carcinogens in diet and cigarette smoke, may confer worse(More)
The objective of this study was to investigate the frequency and type of chromosome segregation patterns in cleavage stage embryos obtained from male carriers of Robertsonian (ROB) and reciprocal (REC) translocations undergoing preimplantation genetic diagnosis (PGD) at our reproductive center. We used FISH to analyze chromosome segregation in 308 day 3(More)
In Wolff-Parkinson-White Syndrome (WPW), presence of accessory pathways causes various tachyarrhythmias that lead to different symptoms and clinical conditions in patients. Atrial fibrillation is observed in about 20-30% of this group of patients. Life threatening malignant ventricular arrhythmias and sudden cardiac deaths are observed in patients having(More)
