The effect of formal education, as opposed to chronological age, on intelligence development has suffered from inadequate empirical investigation. Most studies of this issue have relied on natural variation in exposure to school among children of the same age, thus confounding differences in schooling with differences in other intelligence-related variables. This difficulty can be overcome by a...

BACKGROUND Diabetes mellitus is a chronic disease that can result in various medical, psychological and sexual dysfunctions (SD) if not properly managed. SD in men is a common under-appreciated complication of diabetes. This study assessed the prevalence and determinants of SD among diabetic patients in Tema, Greater Accra Region of Ghana. METHOD Sexual functioning was determined in 300 conse...

INTRODUCTION New diagnostic criteria for lifelong premature ejaculation (PE) have been proposed by the International Society of Sexual Medicine (ISSM), including an intravaginal ejaculatory latency time (IELT) of less than about 1 minute, lack of control over ejaculation, and PE-related distress or bother. AIM The aim of this study was to review evidence supporting the efficacy and safety of ...

The call for a new toxicology is mainly a call for cellular approaches and their computational integration. This article reflects on cell models, which are necessary to facilitate the transition. A mechanistic perspective has prompted the characterization of toxicity pathways and toxicity networks in order to develop robust cell-based assays for toxicity testing. Differing use scenarios for cel...

abstract background: motivation to academic achievement is critical for students of medical sciences, particularly nursing students. it is directly related to high levels of achievement and quality of life. accordingly, diminished motivation would result in academic decline, study and work desertion and exhaustion. therefore, this study aimed to investigate the effect of cognitive behavioural i...

It is an honor to have the opportunity to comment on the article by Koyuncu and colleagues evaluating the possible correlation between intravaginal ejaculato-ry latency time (IELT) and enuresis [1]. Premature ejaculation (PE) is a very common male sexual dysfunction; the prevalence is over 20% in each age group, so there is a need for identification of such patients, as PE leads to personal dis...

BACKGROUND This study aimed to explore the relationship between premature ejaculation (PE) and the serotonin transporter gene-linked polymorphic region (5-HTTLPR) with respect to the biallelic and triallelic classifications. MATERIAL AND METHODS A total of 115 outpatients who complained of ejaculating prematurely and who were diagnosed as having lifelong premature ejaculation (LPE) and 101 cont...

Critics of educational admissions tests assert that tests measure nothing more than socioeconomic status (SES) and that their apparent validity in predicting academic performance is an artifact of SES. The authors examined multiple large data sets containing data on admissions and related tests, SES, and grades showing that (a) SES is related to test scores (r = .42 among the population of SAT ...

Reading difficulties are common and are associated with poor long-term academic achievement. Evaluation of a child's developmental, educational, and family histories in conjunction with standardized screening tests (e.g., Ages and Stages Questionnaires, Parents' Evaluation of Developmental Status, Safety Word Inventory and Literacy Screener) can increase recognition of risk factors for reading ...
