Autonomous Vehicles (AVs) are considered one of the potential solutions to future urban mobility with several promised benefits regarding safety and traffic operation. Despite expected benefits, these vehicles will take decades have full market penetration before that, AVs co-exist Conventional (CVs), which may affect performance owing different driving logic than CVs. The aim this study is qua...

Introduction: This study aimed to discover and document the potential of visual ocular sequelae computer vision syndrome (CVS) among medical students. Methods: cross-sectional case-control was conducted on students (n=4030) five universities in Egypt. All completed a specially designed validated CVS questionnaire survey (CVS-F3). Students with ≥5 symptoms constituted risk group (n=352), while 1...

OBJECTIVES To report our experience over the past 10 years of chorionic villi sampling (CVS) prenatal diagnosis in a high-risk population for chromosomal anomalies, and to analyze, according to the results, the advantages and disadvantages of using quantitative fluorescence polymerase chain reaction (QF-PCR) in amniotic fluid with respect to a conventional semi-direct cytogenetic CVS method in ...

For unrelated samples, principal component (PC) analysis has been established as a simple and effective approach to adjusting for population stratification in association analysis of common variants (CVs, with minor allele frequencies MAF > 5%). However, it is less clear how it would perform in analysis of low-frequency variants (LFVs, MAF between 1% and 5%), or of rare variants (RVs, MAF < 5%)...

The presence of human immunodeficiency virus (HIV) in cervicovaginal secretions (CVS) may be a risk factor for perinatal transmission. CVS of 25 women were evaluated for HIV and HIV mucosal antibodies; 16 infants had gastric aspirates cultured. Maternal plasma HIV was measured by quantitative RNA polymerase chain reaction. Seven women (28%), 4 of 19 pregnant and 3 of 7 nonpregnant, had HIV in C...

OBJECTIVE This study investigated interobserver and intraobserver variability in radiation oncologists' definition of the tumor bed (TB) after breast-conserving surgery (BCS). RESULTS The TB volume, CVS and number of surgical clips were not significantly related to intraobserver variability. Moreover, no correlation was noted between CT slice thickness and interobserver variability (Δinter, D...

The curriculum vitae (CV) has been the traditional method for radiologists to illustrate their accomplishments in the field of medicine. Despite its presence in medicine as a standard, widely accepted means to describe one's professional career and its use for decades as an accomplice to most applications and interviews, there is relatively little written in the medical literature regarding the...

Background: Aneurysmal subarachnoid hemorrhage (aSAH) is an acute neurosurgical emergency with a significant fatality rate. In addition to acute brain injury, a considerable part of patients suffering from aSAH develops secondary brain damage such as cerebral vasospasm (CVS). CVS exacerbates the mortality. Therefore, it is urgently needed to find a biomarker, which could predict secondary brain...

BACKGROUND Charles Darwin (CD), "father of modern biology," suffered from multisystem illness from early adulthood. The most disabling manifestation was cyclic vomiting syndrome (CVS). This study aims at finding the possible cause of CVS in CD. METHODS A literature search using the PubMed database was carried out, and CD's complaints, as reported in his personal writings and those of his rela...

BACKGROUND Beyond the adoption of the principles of horizontal and vertical integration, significant planning and implementation of curriculum reform is needed. This study aimed to assess the effect of the interdisciplinary integrated Cardiovascular System (CVS) module on both student satisfaction and performance and comparing them to those of the temporally coordinated CVS module that was impl...
