We compared clinical outcomes after ventral fixation in dogs with atlantoaxial instability (AAI) on the basis of the presence or absence of atlantooccipital overlapping (AOO). Of 41 dogs diagnosed with AAI and treated ventral fixation, 12 exhibited AOO (AOO group), whereas 29 did not (non-AOO group). The AOO group had significantly higher neurological scores before (P=0.024) and 1 month after (...

ارزیابی خشک‌سالی، ازنظر زمانی و مکانی، برای برنامه‌ریزی‌های کاهش خسارات در استان کردستان اهمیت بسیاری دارد. این تحقیق، از شاخص بارش استانداردشده همچنین، پوشش گیاهی بارزشدة استخراجی تصاویر ماهواره‌ای، به‌منزلة پارامتر تعیین‌کنندة استفاده شده است. به‌این‌منظور، داده‌های آماری ایستگاه‌های هواشناسی شامل حداکثر دمای ماهیانه، مجموع سالیانه نیز سنجندة مادیس به‌کار رفته با مقایسة پارامترهای میانگین سال...

We previously reported age of onset (AOO) modifier genes in the world's largest pedigree segregating early-onset Alzheimer's disease (AD), caused by the p.Glu280Ala (E280A) mutation in the PSEN1 gene. Here we report the results of a targeted analysis of functional exonic variants in those AOO modifier genes in sixty individuals with PSEN1 E280A AD who were whole-exome genotyped for ~250,000 var...

BACKGROUND AND OBJECTIVES Compared to verbal communication, teaching the skill of observation is often shortchanged in medical education. Through a family medicine-art museum collaboration, we developed an elective course for second-year medical students titled the "Art of Observation" (AOO). To evaluate the course's effect on clinical skills, we performed a qualitative evaluation of former stu...

We evaluated the effects of pressure loading produced by gradual aortic occlusion on left ventricular (LV) myocardial contractility by assessing changes in the slope of the LV end-systolic force-diameter (Fes-Des) relation. Eleven adult mongrel dogs were prepared with ultrasonic crystals for measuring LV diameter and a micromanometer for measuring LV pressure. Preload was decreased by vena cava...

OBJECTIVES The purpose of this research was to assess the hemodynamic response to atrial, ventricular, and dual-chamber pacing in patients with Fontan physiology. BACKGROUND Bradycardia, due to sinus node dysfunction or atrioventricular (AV) block, with need for pacing, is common after the Fontan operation. The optimal pacing mode for Fontan patients is unknown, but is critical, as hemodynami...

Although four different primary olfactory pathways have been described in tetrapod vertebrates, polymorphic olfactory sensory neurons comingle in the olfactory epithelium and project axons into separate bulbar regions in teleost fish. However, spatially segregated neurons may exist in the peripheral olfactory organ of lampreys, extant representatives of ancestral jawless vertebrates. In lamprey...

A trait approach was compared to a social cognition approach in predicting discomfort in a laboratory social interaction. The relationships of trait shyness and actual-own/ought-other (AOO) self-discrepancy with multiple aspects of discomfort were evaluated. Results from a canonical correlation analysis showed that the overall relationship between these two predictors of shyness and criteria of...
