myocardial necrosis can be result from a number of causes including nutritional deficiencies, chemical and plant toxins, ischemia and metabolic disorder. the outcome of myocardial necrosis varies depending on the extent of the damage (donald 2001, jubb 1993, radostits 1994, vanvaleet 1986). myocardial infarction without demonstrable of atherosclerosis were reported in a rhesus macaque (gonder 1...

One of the keys to a successful spinal cord fusion is a very sharp cut that minimizes damage of the cord, both at the white matter and the gray matter level. This allows the two interfaces of a severed cord to regrow neurites out of the gray matter core, the vital component of the sensorimotor machinery that makes us move and feel (the so‐called cortico‐trunco‐reticulo‐proprio‐spinal pathway, C...

BACKGROUND Partial hepatectomy is a surgical intervention of the liver that can trigger its regenerative process, where the residual lobes deflagrate a compensatory hyperplasia, causing its restoration almost to the original volume. Nevertheless, depending on the extent of liver damage its regeneration might be impaired. The low-power laser has been studied with beneficial results. AIM To inv...

rats were treated with acetylsalicylic acid (150 mgikg b.w.per os daily) or naproxen (125 mg/kg b.w. per os daily) for six weeks. half of the rats received silymarin (17.5 mgikg b.w. per os daily) in the last three weeks of the experiment. it was found tliat administration of acetylsalicylic acid led to signs of hepatic damage (an increase in serum bilirubin level, alanine aminotransferase and ...

Psychosis is a common non-motor symptom of Parkinson's disease whose pathogenesis remains poorly understood. Parkinson's disease in conjunction with psychosis has been shown to induce injury to extracorticospinal tracts as well as within some cortical areas. In this study, Parkinson's disease patients with psychosis who did not receive antipsychotic treatment and those without psychosis underwe...

Slow oxidative (SO) fibers of the adductor longus (AL) were predominantly damaged during voluntary reloading of hindlimb unloaded (HU) rats and appeared explainable by preferential SO fiber recruitment. The present study assessed damage after eliminating the variable of voluntary recruitment by tetanically activating all fibers in situ through the motor nerve while applying eccentric (lengtheni...

Acute strength exercise elicits a transient oxidative stress, but the factors underlying the magnitude of this response remain unknown. The purpose of this investigation was to determine whether muscle-fiber type relates to the magnitude of blood oxidative stress after eccentric muscle activity. Eleven college-age men performed 3 sets of 50 eccentric knee-extensions. Blood samples taken pre-, p...

Objective(s): The purpose of this study is to investigate the indication function of the calcium circulation-related factors on the damage to muscle strength and contraction function after nerve injury. The target factors include ryanodine receptor (RyR), inositol-1,4,5-triphosphate receptor (IP3R), phospholamban (PLN), cryptocalcitonin (CASQ), ATPase and troponin C (T...
