Reactions of some N-(2,5-dimethoxyaryl)thiobenzamides: en route to an analogue of kuanoniamine A

Abstract: Nitration of 2-aryl-4,7-dimethoxybenzothiazoles 7a–7c produces a mixture of 5- and 6-nitrobenzothiazoles which were distinguished by synthesis of the 2-aryl-4,7-dimethoxy-6-nitrobenzothiaoles 12a–12c by oxidative cyclization of the corresponding nitrothiobenzanilides. Reaction of N-[2,5-dimethoxy-4-(p-tolylsulfonylamino)phenyl]thiobenzamide 17d with base to give 5-methoxy-2-phenyl-6-(p-tolylsulfonylamino)benzothiazole 18 with apparent intramolecular replacement of a methoxy group is also described.

Repeated Sprint Performance in Male and Female College Athletes Matched for VO2max Relative to Fat Free Mass.

Abstract: The purpose of this study was to examine gender differences in repeated sprint exercise (RSE) performance among male and female athletes matched for VO2max relative to FFM (VO2max FFM). Thirty nine male and female college athletes performed a graded exercise test for VO2max and hydrostatic weighing to determine FFM. From the results, 11 pairs of males and females matched for VO2max FFM (mean ± SD; 58.3 ± 4.3 and 58.9 ± 4.6 ml·kg FFM(-1)·min(-1); men and women, respectively) were identified. On a separate day, matched participants performed a RSE protocol that consisted of five 6-sec cycle sprints with 30-sec recovery periods, followed by 5-min active recovery and a 30-sec all-out sprint. Repeated 6-sec sprint performance did not differ between men and women; both maintained power output (PO) until sprint 4. POFFM (W·kg(-1) FFM) did not differ between men and women during the five sprints. During the 30-sec sprint, men achieved a lower peak POFFM than women (11.7 ± 1.5 vs 13.2 ± 1.2); however, the decline in POFFM over 30 sec was greater in women. VO2 (ml·kg FFM(-1)·min(-1)) was lower in men during recovery (24.4 ± 3.8 vs 28.7 ± 5.7) and at the beginning (29.2 ± 4.0 vs 34.7 ± 4.9) and end (49.4 ± 5.0 vs 52.3 ± 4.0). of the 30-sec sprint. These data indicate that men and women with similar aerobic capacities do not respond differently to short repeated sprints but may differ in their ability to recover and perform sprints of longer duration.

Knee Osteoarthritis and the Efficacy of Kinesthesia, Balance & Agility Exercise Training: A Pilot Study

Abstract: Kinesthesia, balance and agility (KBA) neuromuscular exercises are commonly used for rehabilitation of lower extremity injuries. KBA combined with strength training (ST) reportedly improves function among persons with knee osteoarthritis (OA), but independent effects of KBA are unknown. The purpose of this study was to determine the efficacy of KBA exercises, independent of ST, to improve function among persons with knee OA. Twenty participants (69.3, SD 11.4 y) were randomized to 8 weeks, 3-days per week, instructor-lead KBA or ST groups. Self-reported physical function (difficulty with daily living activities such as walking, bending, stair climbing, etc.) was measured at baseline and every two weeks. Community physical activity level, negative and positive outcome expectancies for exercise, self-reported knee stability, and timed 10-stair climb, 10-stair descent, and 'get up and go' 15 m walk were measured at baseline and follow-up. Physical function improved 59% (p = 0.02) with KBA and 40% (p = 0.02) with ST at 8 weeks. Community physical activity level improved only in KBA (p = 0.04); knee stability improved in both KBA (p = 0.04) and ST (p = 0.01). There were no significant between-group differences (p > 0.05). In conclusion, both interventions appear to improve function and knee stability among persons with symptomatic knee OA. As KBA has never been studied as an independent treatment program, our results indicate it is a promising stand-alone intervention worthy of further study.

Personal Digital Assistants as Point-of-Care Tools in Long-Term Care Facilities: A Pilot Study

Abstract: This study used both survey and interview questionnaires. It was designed to assess the feasibility, usability, and utility of two point-of-care tools especially prepared with information relevant for dementia care by staff nurses in a small, a medium-sized, and a large nursing home in Florida. Twenty-five LPN or RN nurses were recruited for the study of their use of one of the tools—either a set of pocket cards (used by the control group) or a pocket PC (used by the experimental group). The findings of our study indicate that personal digital assistants (PDAs) can potentially improve long-term care clinicians' effectiveness and efficiency at work, resulting in better patient care for nursing home residents.

Hot-blooded singers: endothermy facilitates crepuscular signaling in African platypleurine cicadas (Hemiptera: Cicadidae: Platypleura spp.)

Abstract: The cicada genus Platypleura has a wide distribution across Africa and southern Asia We describe endothermic thermoregulation in four South African species that show crepuscular signaling behavior This is the first evidence of thermoregulation in platypleurine cicadas Field measurements of body temperature (Tb) show that these animals regulate Tb through endogenous heat production Maximum Tb measured was 221°C above ambient temperature during calling activity at dusk The mean Tb during dusk activity did not differ from the mean Tb during diurnal activity A unique behavior for cicadas, a temperature-dependent telescoping pulsation of the abdomen, was observed in the laboratory during endogenous warm-up This behavior is part of a unique method of heat generation in endothermic cicadas Males generally call from trunks and branches within the canopy and appear to use endothermy even when the sun is available to elevate Tb Endothermy may provide the cicadas with the advantage of decreasing predation and acoustic competition by permitting calling from perches that most complement their cryptic coloration patterns and that ectotherms cannot use due to thermal constraints In addition, endothermy may permit calling activity during crepuscular hours when atmospheric conditions are optimal for acoustic communication and predation risks are minimal
