OBJECTIVES The aim of this study was to measure the satisfaction of patients with respect to the aesthetics of veneer restorations (VRs) and to identify potential factors influencing their satisfaction. MATERIALS AND METHODS One hundred and eighty VRs of three different types (direct composite, indirect composite and porcelain) were placed on anterior teeth. Patients were asked to fill in que...

We have demonstrated previously that paracrine signaling occurs between medullary thick ascending limb (mTAL) and the contractile pericytes of outer-medullary vasa recta (VR), termed "tubular-vascular cross-talk." The aim of the current study was to determine whether tubular-vascular cross-talk has a functional effect on vasoconstrictor responses to angiotensin II and to determine whether this ...

BACKGROUND Urinary disorders in cats often require subjective caregiver quantification of clinical signs to establish a diagnosis and monitor therapeutic outcomes. OBJECTIVE To investigate use of a video recording system (VRS) to better assess and quantify urination behaviors in cats. ANIMALS Eleven healthy cats and 8 cats with disorders potentially associated with abnormal urination patter...

BACKGROUND The evaluation of pain intensity during the immediate postoperative period is a key factor for pain management. However, this evaluation may be difficult in some circumstances. The pupillary dilatation reflex (PDR) has been successfully used to assess the analgesic component of a balanced anesthetic regimen. We hypothesized that PDR could be a reliable index of pain intensity and cou...

Voice recognition software (VRS) has increasingly been utilised to document clinical care, typically within an electronic health care record and often with the use of ‘templates’. This software has been purported to enhance doctor efficiency, reduce costs and improve patient care1. The aim of the current pilot was the mandatory adoption of VRS embedded into electronic clinical documentation wit...

INTRODUCTION Virchow-Robin spaces (VRS), or perivascular spaces, are compartments of interstitial fluid enclosing cerebral blood vessels and are potential imaging markers of various underlying brain pathologies. Despite a growing interest in the study of enlarged VRS, the heterogeneity in rating and quantification methods combined with small sample sizes have so far hampered advancement in the ...

تحلیل وضعیت ترافیکی و پیشنهاد روش‌های مدیریت جریان ترافیک نقش اساسی در ارزیابی عملکرد بسیاری از سیستم‌های حمل‌ونقلی ایفا می‌کند. بین جمع‌آوری داده‌های ترافیکی، رویکردهای مبتنی‌بر فنّاوری‌های نوین که امکان گرد‌آوری حجم پویای زمانی‌ـ مکانی را فراهم می‌آورند استخراج روندها الگوها تسهیل می‌کنند اهمیت دارند. این پژوهش، تهران به‌منزلة پایتخت ایران، با ویژگی‌های اقتصادی اجتماعی خاصی دارد تنوع سفرها به ...
