Objectives: The aim of this study was to evaluate the hepatoprotective activity resveratrol in patients with morphofunctional liver disorders due mechanical jaundice. Methods: controlled jaundice simulated on rats under anesthesia by drainage choledochus and its plugging. In control group decompression performed 3rd day intravenous infusion 0,9% sodium chloride solution administrated for 12 day...

Underground rock dynamic disasters are becoming more severe due to the increasing depth of human operations underground. temperature and pressure conditions contribute significantly these disasters. Therefore, it is important understand coupled thermo-mechanical (TM) behaviour rocks for long-term safety maintenance underground tunnelling mining. Moreover, investigation damage, strength failure ...

the influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. the incorporation of nanoclay into epoxy enhances the impact resistance of the composites. the impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...

a 21-year old man with cervical spinal cord damage due to diving was admitted in the icu. tracheostomy was performed due to prolonged mechanical ventilation. left lung atelectasis happened frequently. because of the difficulty of bronchoscopy and failing of recruitment, using a double lumen, two tracheal tubes were guided into the left and right lungs through the tracheostomy stoma site. after ...

Osteoarthritis (OA) is associated with increased mechanical damage to joint cartilage. We have previously found that extracellular superoxide dismutase (ECSOD) is decreased in OA joint fluid and cartilage, suggesting oxidant damage may play a role in OA. We explored the effect of forced running as a surrogate for mechanical damage in a transgenic mouse with reduced ECSOD tissue binding. Transge...

 Background: Methanol is a colorless and poisonous liquid that is commonly used as an industrial and household solvent. Methanol poisoning is a rare but extremely hazardous form of in toxication that affects the central nervous system and causes visual disorder, drowsiness, seizures and coma.  Case Presentation: A 29-years-old man with methanol intoxication presented with drowsiness and ac...

We investigate the time-scale invariant changes in electromagnetic and mechanical energy releases prior to a rock failure or a large earthquake. The energy release processes are caused by damage evolutions such as crack propagation, motion of charged dislocation, area-enlargement of sheared asperities and repetitive creep-rate changes. Damage mechanics can be used to represent the time-scale in...

355 nm high-reflective multilayer coatings with or without coevaporated interfaces (CEIs) were prepared by electron beam evaporation under the same deposition condition. Their transmission spectra, surface roughness, and mechanical stress properties were evaluated. Elemental composition analysis of the multilayer interfaces was performed using x-ray photoelectron spectroscopy, and laser-induced...
