PURPOSE The purpose of this study is to evaluate the risk of sequential bilateral total knee arthroplasty (TKA) under 1 anesthesia in patients 75 years or older. MATERIALS AND METHODS Patients aged 75 years or older who underwent sequential bilateral TKA (bilateral group, n=159) and unilateral TKA (unilateral group, n=159) between 2002 and 2012 were selected. All patients were evaluated for u...
One of the major impediments to the integration of lentic ecosystems into global environmental analyses has been fragmentary data on the extent and size distribution of lakes, ponds, and impoundments. We use new data sources, enhanced spatial resolution, and new analytical approaches to provide new estimates of the global abundance of surface-water bodies. A global model based on the Pareto dis...
BACKGROUND Cannabis use is considered a component cause of psychotic illness, interacting with genetic and other environmental risk factors. Little is known, however, about these putative interactions. The present study investigated whether an urban environment plays a role in moderating the effects of adolescent cannabis use on psychosis risk. METHOD Prospective data (n=1923, aged 14-24 year...

Genetic susceptibility testing for common complex disease is a practice that is currently in clinical use. There are two types of gene mutations, and therefore, two varieties of genotype testing: deterministic and susceptibility. As the term suggests, deterministic genes determine whether or not a person will develop a given trait in Mendelian fashion, such as Huntington’s disease. Genotype scr...
Voltage-gated sodium channels are critical determinants of nerve and muscle excitability. Although numerous toxins and small molecules target sodium channels, identifying the mechanisms of action is challenging. Here we used gating-pore currents selectively generated in each of the voltage-sensors from the four a-subunit domains (DI–DIV) to monitor the activity of individual voltage-sensors and...
Off the Ningaloo coast of North West Western Australia, Spangled Emperor Lethrinus nebulosus are among the most highly targeted recreational fish species. The Ningaloo Reef Marine Park comprises an area of 4,566 km2 of which 34% is protected from fishing by 18 no-take sanctuary zones ranging in size from 0.08-44.8 km2. To better understand Spangled Emperor movements and the adequacy of sanctuar...
background: given the lack of consistency in the literature regarding the reliability of the ankle-brachial index (abi) as a valid screening tool and an independent risk indicator of cardiovascular events and mortality, we compared it with angiography as a reference standard test. methods: this case-control study, conducted between 2010 and 2011 in tehran heart center, recruited 362 angiographi...
OBJECTIVE To evaluate the influence of low-dose, enteric-coated aspirin tablets (100 mg/day for 2 years) on colorectal tumour recurrence in Asian patients with single/multiple colorectal tumours excised by endoscopy. DESIGN A double-blinded, randomised, placebo-controlled multicentre clinical trial was conducted. PARTICIPANTS 311 subjects with single/multiple colorectal adenomas and adenoca...
OBJECTIVE To examine the relationships between maternal perceptions of risk, stress, social support, safety-proofing behaviors, supervision practices and unintentional injuries to children under 5 years old. METHODS Household interviews were conducted with 159 mothers who had a preschool-age child. The secondary data were part of a population-based study that collected self-report data and ho...
