objective(s): carbon nanotubes have unique mechanical, electrical, and thermal properties, with potential different applications in nanomedicine, electronics, and other industries. these new applications of carbon nanotubes in different industries lead to the increased exposure risk of nanomaterials to human. up to now, all aspects of carbon nanotubes toxicity are not completely clear following...
STUDY OBJECTIVE Data on poisoning with MCPA (4-chloro-2-methyl-phenoxyacetic acid) are limited to 6 case reports. Our objective is to describe outcomes from intentional self-poisoning with MCPA in a prospective case series of 181 patients presenting to hospitals in Sri Lanka. METHODS Patient information was collected by on-site study physicians as part of an ongoing prospective cohort study o...
Seven infants with persistent neonatal hyperinsulinism were treated in Dhahran Health Centre from 1983 to 1986. The insulin:glucose ratio (serum insulin concentration pmol/l) divided by the blood glucose concentration (mmol/l) ranged from 12 to 636, mean (SD) 177 (201). To control hypoglycaemia, diazoxide (12-24 mg/kg/day) was given in a continuous intravenous glucose infusion (12-22 mg/kg/min)...
Organophosphorus (OP) insecticide self-poisoning is responsible for about one-quarter of global suicides. Treatment focuses on the fact that OP compounds inhibit acetylcholinesterase (AChE); however, AChE-reactivating drugs do not benefit poisoned humans. We therefore studied the role of solvent coformulants in OP toxicity in a novel minipig model of agricultural OP poisoning. Gottingen minipig...
Methaemoglobinaemia may be caused by ingestion of a number of drugs, among them nitrites, some of which are remarkably toxic. This was tragically highlighted by the death of a 17 year old dental nurse after taking a single 1 g tablet of sodium nitrite. These tablets are widely used in the medical and dental profession to prevent rusting of instruments while immersed in disinfectant solutions. T...
Background and Objective: Cardiorespiratory endurance and resting heart rate is the proper guide for cardiorespiratory fitness of people. The aim of this research was to survey the effect of training intensity and volume changes on cardiorespiratory endurance and resting heart rate. Materials and Methods: Forty-five non-athletic healthy B. Sc male students (with an average age of 25±1/87 years,...
Background & Aims: Diabetes is a metabolic disease characterized by chronic hyperglycemia and impaired metabolism of carbohydrates, lipids and proteins. This disease is caused by defects in insulin secretion, insulin function, or both (1, 2). This chronic disease can have serious short-term and long-term consequences that affect the health and quality of life (QOL) of patients (3). Type 2 diabe...
BACKGROUND Obesity begets atrial fibrillation (AF). Although cardiorespiratory fitness is protective against incident AF in obese individuals, its effect on AF recurrence or the benefit of cardiorespiratory fitness gain is unknown. OBJECTIVES This study sought to evaluate the role of cardiorespiratory fitness and the incremental benefit of cardiorespiratory fitness improvement on rhythm contr...
BACKGROUND Sedentary behaviour is a major risk factor for developing chronic diseases and is associated with low cardiorespiratory fitness in adults. It remains unclear how sedentary behaviour and different physical activity subcomponents are related to cardiorespiratory fitness in children. The purpose of this study was to assess how sedentary behaviour and different physical activity subcompo...
Different elements of physical fitness in children have shown a declining trend during the past few decades. Cardiorespiratory fitness and motor skills have been associated with cognition, but the magnitude of this association remains unknown. The purpose of this review is to provide an overview of the relationship of cardiorespiratory fitness and motor skills with cognitive functions and acade...
