The pullout strength of a collagen bone anchor that creates interference fixation as the result of radial swelling on hydration was compared with a Mitek rotator cuff anchor after insertion into the greater tuberosity of human cadaver humeri. Bones were fully hydrated at 37 degrees C. Stiffness, peak load, and the mode of failure were recorded. Real and apparent bone densities were measured. Pe...

Background and Purpose We used a rat model of reversible spinal ischemia to assess the effect of spinal cord temperature on the development of neurological and histopathologic changes after 20 minutes of reversible aortic occlusion. Spinal cord blood flow and CO2 reactivity was tested by using laser Doppler before and 60 minutes after ischemia. Methods In halothane (l%)-anesthetized rats, the s...

Conjugation is the most common horizontal gene transfer (HGT) process that can be affected by environmental change and promote bacterial virulence drug resistance. However, it unknown whether changes influence conjugation ability of marine fish pathogen Vibrio harveyi , thereby affecting its pathogenicity This study systematically analyzes effect stress on V. to obtain shuttle plasmids from Esc...

The first observations of Saturn’s visible-wavelength aurora were made by the Cassini camera. The aurora was observed between 2006 and 2013 in the northern and southern hemispheres. The color of the aurora changes from pink at a few hundred km above the horizon to purple at 1000-1500 km above the horizon. The spectrum observed in 9 filters spanning wavelengths from 250 nm to 1000 nm has a promi...

Introduction and goal: various pathogens colonized in oral cavity that cause systemic disease such as pneumonia, endocarditis, and chronic obstructive pulmonary disease. Denture contamination with pathogenic microorganisms considered as a potential source of contamination between patients and dental staff. The study aimed to compare the effect of microwave radiation in the disinfection complete...
