MicroRNAs (miRNAs) are known to regulate expression of genes under stress. We report here the deep sequencing of small RNAs expressed during control, short and prolonged heat stress and recovery. Genome-wide identification of miRNAs in tolerant (Nagina 22) and susceptible (Vandana) rice cultivars was performed in 16 samples representing root and shoot of 13-day-old seedlings. The expression pro...

OBJECTIVE To determine whether there are significant differences between rapid-eye-movement (REM)-related obstructive sleep apnea (OSA) and non-REM (NREM)-related OSA, in terms of the demographic, anthropometric, and polysomnographic characteristics of the subjects. METHODS This was a retrospective study of 110 patients (75 males) with either REM-related OSA (n = 58) or NREM-related OSA (n = ...

OBJECTIVES/HYPOTHESIS To determine the prevalence of residual obstructive sleep apnea (OSA) in children who had adenotonsillectomy (AT) and to identify the risk factors for residual OSA after AT. STUDY DESIGN Retrospective chart review. METHODS Children with OSA who had AT at a tertiary care children's hospital were reviewed. Data pertaining to demographics, past medical history, body mass ...

STUDY OBJECTIVES Obstructive sleep apnea (OSA) is a common sleep disorder in stroke patients and is associated with prolonged hospitalization, decreased functional outcome, and recurrent stroke. Research on the effect of OSA on cognitive functioning following stroke is scarce. The primary objective of this study was to compare stroke patients with and without OSA on cognitive and functional sta...

BACKGROUND Obstructive sleep apnea (OSA) is a chronic and progressive disease. OSA is associated with increased cardiovascular morbidity and mortality, the risk being more frequently encountered with severe degrees of OSA. Increased sympathetic activation and impaired cardiac autonomic control as reflected by depressed baroreceptor reflex sensitivity (BRS) are possible mechanisms involved in th...

background: pulmonary embolism (pe) is the most life-threatening form of venous thrombosis which causes the majority of mortalities in this category. obstructive sleep apnea (osa) has been indicated as one of the risk factors for thromboembolism because of hemostatic alterations. the present study was designed to seek for the relationship between osa and 30-day mortality of patients with pe. ma...

The aim of this study was to determine the prevalence and associated factors for obstructive sleep apnea (OSA) among children with severe beta-thalassemia. Children with severe beta-thalassemia without a history of bone marrow transplantation were studied. Polysomnography (PSG) was performed in those who habitually snored to identify OSA. One hundred twenty children (aged 9.3 +/- 3.7 years; 42%...

PURPOSE OF REVIEW The purpose of this article is to discuss the anesthetic considerations of obstructive sleep apnea (OSA) patients undergoing ambulatory surgery and the current recommendations based on recent evidence. RECENT FINDINGS It is documented that 75% of patients with high propensity for OSA were not diagnosed prior to ambulatory surgery. An OSA screening questionnaire, the STOP-Ban...

OBJECTIVE Diabetic nephropathy (DN) is a leading cause of end-stage renal disease (ESRD). Obstructive sleep apnea (OSA) is common in type 2 diabetes and increases oxidative stress. Hence, OSA could promote the development and progression of DN. RESEARCH DESIGN AND METHODS This was a cohort study in adults with type 2 diabetes. Patients with known OSA or ESRD were excluded. DN was defined as t...

UNLABELLED Obstructive sleep apnea (OSA) as well as obesity is associated with increased production of reactive oxygen species (ROS). Neutrophils produce great amounts of ROS. The AIM was to evaluate peripheral blood neutrophils ROS production in men with OSA and to establish relations with disease severity and obesity. METHODS Forty-six men with OSA and 10 controls were investigated. OSA was...
