Vanillylmandelic acid protects against reperfusion injury in an experimental animal model of myocardial infarction

Vanillylmandelic acid, a catecholamine end-metabolite, has been shown to have several biological properties in previous studies, despite considered biologically inactive. We examined the potential effects of vanillylmandelic acid on the ischemic heart following myocardial infarction and reperfusion on a rat model. Thirty-four female Wistar rats were randomized into two groups, control and experimental. They were anesthetized and subjected to myocardial infarction through left anterior descending artery ligation. A previously studied dose of vanillylmandelic acid (10 mg/kg) was administered and the following parameters were studied during ischemia and reperfusion: a) mortality b) severity of ventricular tachyarrhythmias c) premature ventricular contractions and d) heart rate. Administration of vanillymandelic acid significantly reduced the severity of ventricular tachyarrhythmias and mortality rate during reperfusion, while it did not affect any other of the parameters studied. In conclusion, reperfusion injury was blunted through vanillylmandelic acid administration, which seems to be mediated by parasympathetic activation.     

The effects of parenteral nutrition on food intake and gastric motility

Frequently, patients receiving parenteral nutrition (PN) report hunger during the parenteral infusion, yet experience early satiety once PN is tapered off. Post-PN satiety can interfere with the ability to consume enough nutrients to maintain body weight and nutritional status. Factors such as caloric quantity of infusate, gastric motility changes, and disease pathology have been related to appetite changes. To investigate the effects of PN on food intake and gastric motility without the complicated interactions associated with disease pathology, four normal, healthy rhesus monkeys (Macaca mulatta) were studied. The monkeys were administered PN in amounts ranging from 25% to 100% of their normal daily caloric intake. Food and water were continuously available. PN consistently suppressed voluntary food intake in direct relationship to the amount of nutrient infused. The frequency of large-amplitude hunger-type gastric contractions decreased from control conditions. Upon cessation of PN, appetite remained suppressed for one to two weeks, indicating a self-limiting physiological basis to post-PN satiety. Thus, reduced appetite following PN termination might occur in the clinical setting and the patients' feelings of satiety may not be completely attributed to lack of cooperation or disease pathology.     

Novel compounds targeting InhA for TB therapy

Tuberculosis (TB) is described as lethal disease in the world. Resistant to TB drugs is the main reason to have unfavourable outcomes in the treatment of TB. Therefore, new agents to replace existing drugs are urgently needed. Previous reports suggested that InhA inhibitors, an enoyl-ACP-reductase, might provide auspicious candidates which can be developed into novel antitubercular agents. In this review, we explain the role of InhA in the resistance of isoniazid. Furthermore, five classes of InhA inhibitors, which display novel binding modes and deliver evidence of their prosperous target engagement, have been debated.
