background many industrial devices have an excessive vibration which can affect human body systems. the effect of vibration on cochlear histology has been as a debatable problem in occupational health and medicine. objectives due to limitation present in human studies, the research was conducted to survey the influence of vibration on cochlear histology in an animal model. materials and methods...

Key disparities between the timing and methods of assessment in animal stroke studies and clinical trial may be part of the reason for the failure to translate promising findings. This study investigates the development of ischemic damage after thread occlusion MCAo in the rat, using histological and behavioural outcomes. Using the adhesive removal test we investigate the longevity of behaviour...

BACKGROUND Sealed irrigation of the capsular bag after removal of the cataractous lens isolates the interior of the capsular bag from the anterior segment, permitting isolated targeting of lens epithelial cells (LECs) in vivo using pharmacologic agents while minimizing the risk of damage to other intraocular structures. OBJECTIVES To assess the ability to deliver a nonspecific, extremely toxi...

  Aims: Ocular injury by mustard gas (HD) leads to severe eye damage. Long term characterization of mustard gas ocular toxicity has not been described in detail yet. Present study was performed in order to explore chronic histological and immunopathologic effects of HD ocular exposure and try to find etiology for these effects.   Methods: This descriptive case study was performed on corneal and...

background little is known about the possible influence of demographic and histological risk factors on the survival of patients with esophageal and gastric cancer. objectives based on the available registry and follow-up information, this study compares 1-5 year survival rate of gastric and esophageal cancer. patients and methods through a concurrent (prospective) cohort study, all 366 patient...

BACKGROUND Several renal histopathological features, including mesangial hypercellularity, glomerulosclerosis, tubular atrophy and interstitial fibrosis, are considered to be independent predictors of end-stage renal failure in patients with glomerular diseases. Mesangial proliferative glomerulonephritis (MesPGN) is characterized by proliferations of mesangial cells with increase in mesangial m...

ABSTRACT The flavonoid kaempferol has attracted research attention as a potential adjuvant during chemotherapy. This study aimed to evaluate the protective effects of against ovarian damage in cisplatin-treated mice. Two groups mice received saline solution (intraperitoneal injection [i.p.]; control) or single dose cisplatin (5 mg/kg body weight, i.p.). Moreover, two other were pretreated with ...

background: serial measurement of  hepatitis b virus (hbv) dna levels in the liver and its relation with liver damage and serum hbv dna levels are guide to begin and/or end a treatment course. this study evaluated the relationship between liver hepatitis b dna viral load with liver histology in patients with chronic hepatitis b (hbv). methods:  thirty patients with chronic anti-hbe positive hep...

Candida albicans is responsible for a number of life-threatening infections and causes considerable morbidity and mortality in immunocompromised patients. Previous studies of C. albicans pathogenesis have suggested several steps must occur before virulent infection, including early adhesion, invasion, and late tissue damage. However, the mechanism that triggers C. albicans transformation from y...

PURPOSE Vessel damage after clamping may affect the success of surgical operations. A new pressure controlled clamp (SMA clamp) was designed using super elastic property of shape memory alloy (SMA) to realize atraumatic vessel occlusion. The ability and biological effect of the SMA clamp to control pressure was investigated in vivo. METHODS The loading-displacement curves of the SMA clamps (e...
