Weight loss is the result of a sustained negative energy balance, which is typically achieved by decreasing food intake and/or increasing physical activity. Current evidence suggests that acute energy deficits of ~4820 kJ elicit contrasting homeostatic responses when induced by exercise and food restriction but the response to government-recommended energy deficits is unknown. Twelve healthy me...

Using the Goddard High Resolution Spectrograph (GHRS) onboard the Hubble Space Telescope, we have obtained high S/N echelle observations of the weak interstellar O I λ1356 absorption toward the stars γ Cas, Per, δ Ori, Ori, 15 Mon, τ CMa, and γ Ara. In combination with previous GHRS measurements in six other sightlines (ζ Per, ξ Per, λ Ori, ι Ori, κ Ori, and ζ Oph), these new observations yield...

A protocol of 75 lengthening contractions (LCP) administered to skeletal muscles of mice causes an initial force deficit owing to the mechanical disruption of sarcomeres and a reduction in calcium release from the sarcoplasmic reticulum. During the 3 days following the LCP, a 'sealing off process' and inflammatory response occurs. The reactive oxygen species (ROS) released by invading inflammat...

The oxygen deficient mesopelagic layer (ODL) off Peru has concentrations below 5 μmol O 2 kg –1 and is delimited by a shallow upper oxycline with strong vertical gradient more gradual lower ( lOx ). Some regions show narrow band of slightly increased within the ODL, an intermediate iO CTD, lowered Acoustic Doppler Current Profiler (LADCP, 300 kHz) profiles were taken on shelf edge outside down ...

Abstarct Background: Base deficit is a non-respiratory indicator of acid base status that evaluates the severity of shock at the cellular level. Base deficit results from cellular metabolism of pyruvate under anaerobic conditions. In this situation, base deficit is a sensitive marker of the magnitude of anaerobic metabolism and tissue oxygen deficit [1]. Several studies have shown a strong posi...

introduction: the purpose of this study was to determine na-ca exchanger 2, 3 (ncx2, 3) protein level changes during 2, 5, 10, 15 days after induction of normobaric hyperoxia (ho) preconditioning. materials and methods: rats were divided in two experimental groups. the first group was exposed to 95% inspired ho for 4 h/day for 6 consecutive days (ho). the second group acted as control, and was ...
