Higher education is faced with the question of how large numbers students can be supported to learn complex skills without increasing teachers' supervision time proportionally and while preserving, or preferably improving, quality. Practicing only once does not work. Students need repetitive practice, feedback, structured support master a skill. They gain insight into what went well could impro...

OBJECTIVE To examine the influence of state laws and district policies on district-wide elementary school and middle school practices related to physical education (PE) time and the percentage of moderate-to-vigorous physical activity (MVPA) time during PE. DESIGN Multivariate, cross-sectional analysis of state laws, district wellness and PE policies, and district PE practices for school year...

BACKGROUND The frequency of the thrombophilic genetic variants factor V Leiden (FVL) G1691A, prothrombin G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T in acutely symptomatic ambulatory patients with idiopathic pulmonary embolism (PE) has not been measured. METHODS This prospective case-control study included patients presenting to urban emergency departments (EDs) with chest ...

For many decades it has been thought that lifelong premature ejaculation (PE) is only characterized by persistent early ejaculations. Despite enormous progress of in vivo animal research, and neurobiological, genetic and pharmacological research in men with lifelong PE, our current understanding of the mechanisms behind early ejaculations is far from complete. The new classification of PE into ...

Syncope is the state of lack of consciousness and temporal loss of postural tone. Syncope might be in association with a variety of benign and life-threatening conditions. Pulmonary embolism (PE) has been shown to be associated with syncope in 13-30 percent of cases. This article presents a novel case report of PE whom syncope was his only manifestation.

premature ejaculation (pe) is one of prevalent male sexual dysfunctions worldwide. despite many psychiatric backgrounds, yet there are speculations about organic etiologies considering both anatomic and physiologic points of view. this survey assesses effect of frenular web preservation on premature ejaculation. one thousand and forty otherwise healthy men being visited for urolithiasis (asympt...

background: premature ejaculation is one of the most problems in clinical practice. the association between varicocele and premature ejaculation was poorly understood. the effects of varicocelectomy on premature ejaculation in varicocele patient was studied. objectives: the aim of this study was to determine the impacts of varicocelectomy on patients with both premature ejaculation and varicoce...

The Drosophila wing imaginal disc is a sac-like structure that is composed of two opposing cell layers: peripodial epithelium (PE, also known as squamous epithelia) and disc proper (DP, also known as pseudostratified columnar epithelia). The molecular mechanism of cell morphogenesis has been well studied in the DP but not in the PE. Although proper Dpp signalling activity is required for proper...
