| Since you're presumably young, you should use almost all of your limited time getting aerobic exercise like running, biking, or brisk walking, said William J. Evans, director of the Nutrition, Metabolism, and Exercise Laboratory at the University of Arkansas for Medical Sciences. That's because "regular aerobic exercise increases life expectancy by decreasing the risk of a host of chronic diseases," ... | |

| • | Tranexamic Acid Reduces Perioperative Blood Loss in Adult Patients Having Spinal Fusion Surgery |
|
BACKGROUND: Spinal reconstructive surgery in adults can be associated with significant blood loss, often requiring allogeneic blood transfusion. The objective of this randomized, prospective, double-blind, multicenter study was to evaluate the efficacy of tranexamic acid (TXA) in reducing perioperative blood loss and transfusion in adult patients having elective posterior thoracic/lumbar instrumented spinal fusion surgery. METHODS: One hundred fifty-one adult patients were randomized to receive either a bolus of 10 mg/kg IV of TXA after induction followed by a maintenance infusion of 1 mg/kg/hr of TXA, or an equivalent volume of placebo (normal saline). The primary outcome was the total perioperative estimated and calculated blood loss intraoperatively and 24 h postoperatively. Secondary outcomes were incidence of allogeneic blood exposure, and duration of hospital stay. RESULTS: Four patients were withdrawn for identifiable surgical bleeding, therefore 147 patients were included in the analysis. The total estimated and calculated perioperative blood loss was approximately 25% and 30% lower in patients given TXA versus placebo (1592 ± 1315 mL vs 2138 ± 1607 mL, P = 0.026; 3079 ± 2558 vs 4363 ± 3030, P = 0.017), respectively. There was no difference in the amounts of blood products transfused, and length of stay between the two groups. TXA, surgical duration, and number of vertebrae fused were independent factors related to perioperative blood loss. Predictors for the need for allogeneic red blood cell transfusion were ASA classification, surgical duration and number of levels fused. CONCLUSIONS: TXA significantly reduced the estimated and calculated total amount of perioperative blood loss in adult patients having elective posterior thoracic/lumbar instrumented spinal fusion surgery. |

| • | Systemic Acquired Resistance Induced in Cucumber Plants Against Powdery Mildew Disease by Pre-inoculation with Tobacco Necrosis Virus |
| Systemic Acquired Resistance (SAR) in cucumber plants against powdery mildew disease, caused by Sphaerotheca fuliginea (Schlechtend Fr.) Pollacci, was induced by localized infection in cucumber cotyledons with Tobacco Necrosis Virus (TNV). Inoculation of the two cotyledon leaves significantly reduced powdery mildew severity on cucumber true leaves similar to the effect of fungicide. TNV-local lesions developed plants still protected against powdery mildew for 16 days. The level of protection was higher in the upper true leaves when compared with the bottom ones. Antifungal protein was extracted and partially purified by DEAE-cellulose column chromatography from cucumber TNV-inoculated plants only. Bioassay detection for antifungal activity indicated that, 0.6 M NaCl fraction had the highest activity. SDS-PAGE of partially purified 0.6 M NaCl fraction protein indicated the presence of a single protein band with a molecular weight of about 30 kDa. This protein was extracted from upper TNV-uninoculated true leaves of plants inoculated on the cotyledon leaves, which acquired systemic resistance against powdery mildew challenge inoculation. In vitro study of the antifungal activity of these proteins showed that only 0.6 M NaCl fraction has direct antifungal activity towards S. fuliginea conidial spores. The induced systemic resistance was not accompanied with the activity of β-1, 3 glucanase. | |
