In several laboratory meetings, we discussed the challenges that face trainees in behavioral pharmacology. Major concerns, such as a difficult funding climate and limited academic job prospects were discussed at first. However, we decided to concentrate on ways to meet these challenges; versus focusing on negatives and listing gripes. Within this more constructive framework, we identified the i...
Subclinical thyroid disease is defined biochemically by an abnormal thyrotropin (TSH) level and normal serum-free thyroxine level. The prevalence of this condition varies according to the reference range for TSH and geographic or demographic factors. Recently, several studies, including our community-based cohort studies, have reported on the incidence of subclinical thyroid disease in Korea. U...
INTRODUCTION Until recently osteoporosis was seen mainly as a woman's problem. However, in the last ten years there has been rising awareness in society that osteoporosis constitutes an inseparable element of getting old for men as well. The aim of the research was to evaluate men's knowledge about osteoporosis and its risk factors contributing to the development of the disease. MATERIAL AND ...
Many undergraduate students lack a sound understanding of information literacy. The skills that comprise information literacy are particularly important when combined with scientific writing for biology majors as they are the foundation skills necessary to complete upper-division biology course assignments, better train students for research projects, and prepare students for graduate and profe...
OBJECTIVES The aim of this study was to model the avoidable burden of the risk factors of road traffic crashes in Iran and to prioritize interventions to reduce that burden. METHODS The prevalence and the effect size of the risk factors were obtained from data documented by the traffic police of Iran in 2013. The effect size was estimated using an ordinal regression model. The potential impac...
Numerous recent reports document a lack of reproducibility of preclinical studies, raising concerns about potential lack of rigor. Examples of lack of rigor have been extensively documented and proposals for practices to improve rigor are appearing. Here, we discuss some of the details and implications of previously proposed best practices and consider some new ones, focusing on preclinical stu...
An estimated quarter of a trillion US dollars is invested in the biomedical research enterprise annually. There is growing alarm that a significant portion of this investment is wasted because of problems in reproducibility of research findings and in the rigor and integrity of research conduct and reporting. Recent years have seen a flurry of activities focusing on standardization and guidelin...
The effects of unilateral lid closure and artificial esotropia on the development of visual acuity were studied in visually immature rhesus monkeys (Macaca mulatta). Irreversible amblyopia occurred in all animals whose lids were sutured between birth and nine weeks of age. Lid closure at the age of 12 weeks did not produce amblyopia. During the age of susceptibility only brief periods of occlus...
PURPOSE The aim of this study was to evaluate the cost effectiveness of ranibizumab compared with verteporfin photodynamic therapy (vPDT) or no treatment (observation) in patients with visual impairment due to myopic choroidal neovascularization (CNV). METHODS A Markov model with health states defined by best-corrected visual acuity and a 3-month cycle length was developed. It had a healthcar...
Two groups of cattle were used to develop (model data set: 384 heifers, 228 ± 22.7 kg BW, monitored over a 225-d feeding period) and to validate (naïve data set: 384 heifers, 322 ± 34.7 kg BW, monitored over a 142-d feeding period) the use of feeding behavior pattern recognition techniques to predict morbidity in newly arrived feedlot cattle. In the model data set, cattle were defined as morbid...
