Necrosis

Breakthrough in the treatment of cardiovascular disorder Myocardial Infraction Introduction: Acute Ischemic necrosis of an area of myocardium is known as myocardial infraction (Heart attack). Heart Muscle necrosis occurring as a result of critical imbalance between coronary blood supply and myocardial demand is called myocardial infraction. Suddenly myocardial loses its blood supply. In most of the patients Myocardial Infraction develops in left ventricle. [1] The main cause of myocardial…

million, sodium toxicity occurs, resulting in necrosis which may kill the plant; sodium deficiency poses no threat to the plant as it is not an essential element. Chloride is a micronutrient, essential in most plants assisting in metabolic processes, photosynthesis, and osmosis. Chloride toxicity normally occurs at about seventy parts per million and leads to necrosis; chloride deficiency occurs at less than two parts per million and can cause necrosis…

The cutting current results in tissue vaporization with minimal coagulative necrosis. Twenty men have enrolled in the second phase of the study. Their mean age is 63.2 +/- 7.5 years and their mean follow-up is 4.6 months (range, 1 to 12). Their mean American Urological Association (AUA) symptom score declined from 22.9 +/- 4.2 preoperatively…

Ischemia is a state of tissue oxygen deprivation accompanied by a reduced washout of the resulting metabolites (1). Reperfusion is the restoration of blood flow to the ischemic tissue. Despite the unequivocal benefit of reperfusion of blood to an ischemic tissue, reperfusion itself can elicit a cascade of harmful reactions that injure tissue(2). Studies have shown that renal ischemia - reperfusion injury in addition to kidney tissue, will also be affected distant organs such as the brain (3),…

1. What factors predisposed Mr. W. to acute kidney injury? Some of the factors that caused Mr. W’s acute kidney injury are fever of 38.5° C, severe abdominal pain & nausea due to pancreatic inflammation with intra-abdominal ascites. One of the symptoms of ascites is infection which can cause kidney failure if not treated (ACG, 2013). Two different CT scan with contrast media performed can result to contrast-induced nephropathy due to preexisting decline in renal function. CIN can be defined as…

Introduction: Upper limb ischemia presenting in the neonatal period is exceedingly rare1. Limb ischemia occurring in utero has three main causes: thrombosis, embolism, and in utero compression2. Neonatal arterial thrombosis and embolism are serious conditions that often result in high morbidity and mortality.3,4 Approximately 90% of neonatal arterial thromboembolic (TE) events are linked to iatragenic causes, including catheterization.4,5 TE events occurring in utero are especially rare, and can…

Groups of genotypes of trees were each treated with control conditions, irrigation, fertilization, and a combination of both irrigation and fertilization. Incidences of attack were recorded regularly using necrosis at the bore site as an indication of the presence or absence of attack. Necrosis was absent from the sycamore, sweetgum, and loblolly pine trees, thus no attacks were made against these. Insects collected from the traps were identified as predominantly Scolytidae. Among the 28 species…

1.7.3.4. Hydrogen sulphid test (MacFaddine, 1980): Tubes of triple sugar iron agar media were inoculated by suspected culture through stabbing into the butt and the slant then covered with sterile melted paraffin wax and incubated anaerobically for 48 h at 37°C, appearance of blackening in the butt indicates H2S production. 1.7.3.5. Sugar fermentation test (Willis, 1977): Suspected culture was inoculated to 1% peptone water tubes containing 2% bromocresol purple and 1% quantities of the…

Fish are cold-blooded aquatic vertebrates. They are highly susceptible to seasonal and diurnal variations in water temperature in their habitats. Any abnormal change in temperature may influence fish survival, change physiological, biochemical function and enzymatic activities. In order to address this, we exposed Bighead carp Aristichthys nobilis to an increase in temperature from 28°C to 38°C and measured the effects on histopathological changes in gill, liver and kidney tissues, physiological…

The medial side of ankle is very interesting because it has the important structure; bones, deltoid ligament and tarsal tunnel which composes of posterior tibial artery, posterior tibial nerve and their branches. The injuries at ankle have numerus injuries of these structures such as medial malleolus fracture, ligament sprain, ligament tear, nerve entrapment, and impair blood circular. For ankle sprains, deltoid ligament injury may occur increase to 18% (Lin et al. , 2006). Chronic instability…
