the study was consequently investigated effect of different tanning methods on apparent density, thickness, tensile strength and also extension percentage in three different tanning (chromic, alum and vegetable) of grown part of ostrich skins (n = 15; 12 to 14 months). average apparent density and thickness of leathers were 0.7 ± 0.0gr/cm2 and 1.7 ± 0.1 mm, respectively. the breaking load, tens...

Esophagogastric anastomotic leaks complicate 5% to 20% of esophagectomies for esophageal cancer. Keratinocyte growth factor-2 (KGF-2) is a newly identified growth factor that accelerates skin incisional healing. An animal experiment was done to test the hypothesis that KGF-2 would enhance esophagogastric anastomotic wound healing. Forty rats had single-layer esophagogastric anastomoses construc...

the aim of the present study was to investigate the physicochemical performances at three sites on skin, namely the diagonal, neck and leg based on different age groups. eighteen skins pieces in 6 m, 6 m to 1 yr and 1 yr to 1.5 yr of age were selected to represent means of the respective age groups with regard to skin area. the skin area were7.4±1.41, 13.5±1.4 and 18.2±1.1 ft2 for the ostriches...

Keratinocyte growth factor (KGF) is a potent mitogen that prevents lung epithelial injury in vivo. We hypothesized that KGF treatment reduces ventilator-induced lung injury by increasing the alveolar epithelial tolerance to mechanical strain. We evaluated the effects of in vivo KGF treatment to rats on the response of alveolar type II (ATII) cells to in vitro controlled, uniform deformation. KG...

The starting material used in this study was a cake generated during thermo-mechanical fractionation of sunflower (Helianthus annuus L.) whole plant in a twin-screw extruder. It was slightly deoiled (16.7% of oil in dry matter). Composed mainly of fibers and proteins, it could be considered as a natural composite and was processed successfully into fiberboards by thermo-pressing. This study aim...

BACKGROUND Chewing is composed of structures that must be balanced to achieve optimal function and bite force is one of the components of this function. AIM To analyze the bite force of candidates for bariatric surgeries. METHOD Was used surface electromyography Miotool 200/400 (Miotec® , Porto Alegre/RS, Brazil) coupled to bite load cell, SDS1000 sensor, to record the maximum force reading...

Introduction. Baropodometry is used to measure the load distribution on feet during rest and walking. The aim of this study was to evaluate changes in plantar foot pressures distribution due to period of working and due to stretching exercises of the posterior muscular chain. Methods. In this transversal study, all participants were submitted to baropodometric evaluation at two different times:...

Objective The study evaluated the influence of abutment design on the retention of implant-cemented metal copings. Material and methods Two abutments of the same system with the same indications, height and the total occlusal convergence, but of different designs were evaluated. Ten RN synOcta abutments (Straumann, Waltham, MA) and ten RN titanium solid abutments (Straumann, Waltham, MA) were t...

BACKGROUND The lowest contact pressure point is presumed to be the best site to harvest an osteochondral plug and minimize morbidity. HYPOTHESIS Patellofemoral contact pressures are not uniform and are lowest along the medial patellofemoral articulation. STUDY DESIGN Controlled laboratory study. METHODS Seven cadaveric knees were tested with an electroresistive, dynamic pressure sensor pl...
