We used this method on African and Asian elephants. Small capsules

(30 g) containing a temperature-sensitive transmitter and a memory for onboard data storage were hand-fed 71 times to elephants (N=21) and T(b) was measured during gut passage. In 64 cases, sensors were successfully retrieved. The operation and reliability of our data loggers was sufficient and compared favourably with any other published method. (C) 2010 Elsevier Ltd.

“Various missense mutations were identified in TAR DNA-binding protein-43 (TDP-43) in patients with amyotrophic lateral sclerosis (ALS). To explore the toxic effect of mutant TDP-43, we generated stable transfection of wildtype and mutant TDP-43 in motor neuron-like cell line. We found that mutant TDP-43 induced mitochondrial dysfunction, oxidative damage and nuclear accumulation of nuclear factor E2-related factor 2 (Nrf2). Selleck DihydrotestosteroneDHT Nrf2 is an indicator and modulator of oxidative stress and is known to promote the expression of phase parallel to detoxification enzyme including heme oxygenase-1 (HO-1). However, HO-1 was down regulated in cells expressing the mutant TDP-43, and could not be restored by sulforaphane which is a known stimulator of Nrf2 and phase parallel to detoxification enzyme, including HO-1. Nevertheless, sulforaphane

reduced the level of lactate dehydrogenase and lipoperoxidation products in cells expressing TDP-43 mutant. However, sulforaphane could upregulate the expression of HO-1 and NAD(P)H/quinone oxidoreductase-1 (NQO-1) selleck products in cells transfected with the empty vector and the wild-type TDP-43. Thus, sulforaphane protected cells against mutant TDP-43 independent of Nrf2-antioxidant response element (ARE) pathway. How mutant TDP-43 reduces expression of HO-1 and prevents sulforaphane from activating Nrf2 signaling remains to be investigated. (C) 2010

“This ROS1 paper addresses a variable-dependence (VD) MC method developed based on a previous attempt (VI-MC method) (J. Therm. Biol. 29 (2004), 515) to be incorporated in a thermoregulatory model. Simulated individuals with anthropometrics by VI- and VD-MC methods for US Army population were compared using principal component analysis and Fisher’s exact tests. The results indicated that VD-MC data represented overall body size as the primary component and body shape as the secondary component that were more realistic and similar to the measured US Army data (p > 0.05) rather than VI-MC data (p < 0.05). Such differences consequently affected individual thermoregulatory responses to simulated heat stress. The VD-MC method provides a more realistic representation of individual variability and thus underpins more realistic predictions of individual thermoregulatory responses. Published by Elsevier Ltd.
