Recent advances in phage therapy, iron chelation therapy, antimicrobial peptides, prophylactic vaccination, photodynamic therapy, and nitric
oxide (NO)-based therapies have all been shown to have activity against A. baumannii. However, before these approaches can be used see more clinically there are still limitations and remaining questions that must be addressed.”
“It is known that warm and humid environment reduces human physical performance. The present study examined whether the use of an ice-vest in such conditions can improve cycling performance.
Seven participants cycled with consecutive, non-stop, 10-minute cycles of nine minutes at 60% of their (V) over dot O-2 max punctuated by a one-minute sprint at 80% (V) over dot O-2 max. The cycling protocol was continuously repeated until exhaustion. The protocol was performed with the ice-vest (ICE), worn after SHP099 mouse 30 min of cycling, and without the ice-vest throughout the protocol (CON). Ventilatory and thermal responses were continuously
recorded. Electromyographic (EMG) signals from four muscles of the dominant leg were recorded over one minute, and subjective sensations were evaluated at 10-minute intervals. At exhaustion, the exercise time was recorded.
Exercise time improved significantly while wearing the ice-vest from 61 min and 29 s to 74 min and 14 s (+21.5% +/- 7.6: p <0.05). Mean power frequency and amplitude of the EMG revealed decreased neuromuscular VE-821 ic50 fatigue during ICE compared to CON. Ventilatory responses indicated a tendency towards lower ventilation, respiratory quotient was significantly lower and both thermal parameters and subjective sensations indicated lower thermal strain during ICE in comparison to CON.
These results suggest that wearing an ice-vest during cycling in warm and humid conditions decreases thermal and physical strain, thereby improving cycling performance. (C) 2011 Elsevier Ltd. All rights reserved.”
“Prenatal
exposure to glucocorticoids (GCs) leads to affective dysfunction in adulthood, which may be associated with the alterations in hypothalamic-pituitary-adrenal (HPA) axis. Physical exercise has been shown to ameliorate depressive symptoms. The objectives of present study were to investigate whether prenatal exposure to GCs induces depression-like behaviors in adult offspring rats, and determine whether swimming exercise alleviates the depression-like behaviors induced by this paradigm. Pregnant rats received dexamethasone (DEX) (0.1 mg/kg/day) in the last third of pregnancy or vehicle. DEX treatment reduced body weight in 1, 3, 6, 9-week old male offspring, and 3, 6, 9-week old female offspring. DEX treatment resulted in an elevated level of serum corticosterone in adult offspring (9 weeks).
