BACKGROUND Spermatozoa with large vacuoles (SLV) may have a negative impact on embryo development. The origin of these vacuoles is unknown. We evaluated acrosome and nucleus alterations in isolated SLV, versus unselected spermatozoa. METHODS We studied 20 patients with teratozoospermia. Spermatozoa from the native semen sample and spermatozoa presenting a vacuole occupying >13.0% total head a...

BACKGROUND Left ventricular (LV) effects on right ventricular (RV) function are well known. Less is understood about the effect of the RV on systemic LV mechanics. To determine this interaction, we compared systemic LVs with and without an RV mechanically coupled to them. METHODS AND RESULTS MR myocardial tagging was used to examine 18 subjects with systemic LVs: 10 with functional single LVs...

BACKGROUNDS/AIMS The future liver remnant (FLR) is usually calculated as a ratio of the remnant liver volume (RLV) to the total functional liver volume (RLV/TFLV). In liver transplantation, it is generally accepted that the ratio of the graft volume to standard liver volume (SLV) needs to be at least 30% to 40% to fit the hepatic metabolic demands of the recipient. The aim of this study was to ...

OBJECTIVES To identify potential risk factors such as smoking, cardiovascular diseases (CVD), denture wearing, and consuming vitamin rich foods, and its relation to the development of sublingual varices (SLV). METHODS This cross-sectional observational study was conducted on patients who attended the Department of Dentistry at The University of Jordan Hospital, Amman, Jordan between February ...

Though the structure of the substrate stem loop I (SLI)-stem loop V (SLV) kissing loop junction of the Varkud Satellite ribozyme has been experimentally characterized, the dynamics of this Mg2+-dependent loop-loop interaction have been elusive. Specifically, each hairpin loop contains a U-turn motif, but only SLV shows a conformational shift triggered by Mg2+ ion association. Here, we use molec...

BACKGROUND School-located influenza vaccination (SLV) programs have the potential to mass-vaccinate all enrolled children, but parental consent is required. OBJECTIVE To examine parental attitudes and determine predictors of parental consent for vaccination of schoolchildren through SLV programs. PATIENTS/METHODS Surveys were distributed to parents of 4517 children during 2009-2010 (year 1)...

BACKGROUND Bleeding within the supraglottic region can be a lethal complication after CO(2) laser microsurgery. Our aim was to propose endoluminal anatomical landmarks to locate the superior laryngeal vessels resulting in a safer microsurgery. METHODS Endoluminal dissections were made in 22 larynges without laryngeal disease. RESULTS The neurovascular structures were in the superior third o...

Substrate recognition by the Neurospora Varkud satellite ribozyme depends on the formation of a magnesium-dependent kissing-loop interaction between the stem-loop I (SLI) substrate and stem-loop V (SLV) of the catalytic domain. From mutagenesis studies, it has been established that this I/V kissing-loop interaction involves three Watson-Crick base pairs and is associated with a structural rearr...

BACKGROUND School-located vaccination against influenza (SLV-I) has the potential to improve current suboptimal influenza immunization coverage for U.S. school-aged children. However, little is known about SLV-I's cost-effectiveness. The objective of this study is to establish the cost-effectiveness of SLV-I based on a two-year community-based randomized controlled trial (Year 1: 2009-2010 vacc...

INTRODUCTION Video-assisted thoracoscopic surgery (VATS) has gained wide acceptance for the pediatric population. Single-lung ventilation (SLV) has been suggested for thoracoscopic lung resection to provide better surgical exposure, but its role and sequelae compared with double-lung ventilation (DLV) have not been determined. The aim of this study was to investigate the feasibility and effects...
