background: with the aim of developing methods that could increase the fracture resistance of structurally compromised endodontically treated teeth, this study was conducted to compare the effect of three esthetic post systems on the fracture resistance and failure modes of structurally compromised and normal roots. materials and methods: forty five extracted and endodontically treated maxillar...

Objective: The purpose of this study was to investigate the effect of moderate and high intensity endurance trainings with genistein consumption on tumor necrosis factor alpha (TNF- α) and interferon gamma (INF- γ) in streptozotocin induced diabetic rats. Materials and Methods: In this experimental study, 64 male diabetic rats were randomly assigned into 8 groups of 8 (1) first week control (2...

30 31 Purpose: To examine whether i) objective markers of sleep quantity and quality are altered in 32 endurance athletes experiencing overreaching in response to an overload training program and ii) 33 whether potential reduced sleep quality would be accompanied with higher prevalence of upper 34 respiratory tract infections in this population. 35 Methods: Twenty seven trained male triathletes...

introduction: low back pain is one of the most common musculoskeletal disorders,which is prevalent among the public population. depending on the severity of the patients’ pain, different treatments are selected for them. few studies have addressed, so far, the therapeutic effects of laser in such pains and different results have been published in this regard. the aim of this study is to investi...

in aim of this research was to investigate the effect of a decrease in the number of practice sessions and an increase in exercise intensity on aerobic and anaerobic power, body fat percentage, and body mass index. 80 subjects (average age: 20.2±1.53 years and height: 160.18±5.43cm) were divided into 4 groups (3 experimental groups and one control group). the experimental groups exercised with ...

This paper introduces a novel partition-based regression approach that incorporates topological information. Partition-based regression typically introduce a quality-of-fit-driven decomposition of the domain. The emphasis in this work is on a topologically meaningful segmentation. Thus, the proposed regression approach is based on a segmentation induced by a discrete approximation of the Morse-...

PURPOSE/OBJECTIVES To examine the effects of an opioid taper algorithm on the length of taper, pain levels, withdrawal symptoms, and satisfaction with pain management in hematopoietic progenitor cell transplant (HPCT) recipients and nurse documentation of patient response to taper. DESIGN Quasi-experimental. SETTING A 32-bed HPCT unit in a large tertiary U.S. healthcare center. SAMPLE 106...

Assessment of the head-stem taper junction requires the estimation of material loss from the taper surfaces of both femoral head and stem. This paper describes a method for the measurement and analysis of material loss from the modular taper junction of hip replacements, in particular femoral stem tapers where generally the entire taper surface has been engaged. In such cases no direct unengage...

BACKGROUND No documentation in the literature about taper of cast posts. This study was conducted to measure the degree of cast posts taper, and to evaluate its suitability based on the anatomy aspects of the common candidate teeth for post reconstruction. METHODS Working casts for cast posts, prepared using Gates Glidden drills, were collected. Impressions of post spaces were made using poly...
