Carbapenem resistant Gram negative bacilli (CR-GNB) are an increasing problem worldwide, and rectal swab surveillance is recommended as a component of infection control programs. The performance of an in-house medium (modified CDC protocol) for detecting CR-GNB in surveillance rectal swab was evaluated and compared with a chromogenic medium (ChromID CARBA). 40 rectal swab specimens were taken f...
We investigated if calorie restriction (CR) preserved skeletal muscle oxidative capacity with aging after accounting for life span extension by CR, and determined if mitochondrial content, mitochondrial DNA integrity, and peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1alpha) were involved. Ad libitum-fed (AL) and CR animals representing young adult, late middle age, a...
Limiting food intake attenuates many of the deleterious effects of aging, impacting upon healthspan and leading to an increased lifespan. Whether it is the overall restriction of calories (calorie restriction: CR) or the incidental reduction in macronutrients such as protein (protein restriction: PR) that mediate these effects is unclear. The impact of 3 month CR or PR, (10 to 40%), on C57BL/6 ...
We demonstrate efficient amplification of few-optical-cycle mid-IR pulses in single-pass continuously pumped laser amplifiers based on polycrystalline Cr(2+):ZnS and Cr(2+):ZnSe. The 1.7 W output of a Kerr-lens mode-locked master oscillator at 2.4 µm central wavelength, 79 MHz repetition rate was amplified to 7.1 W and 2.7 W in Cr(2+):ZnS and Cr(2+):ZnSe, respectively. High peak power of the in...

Introduction: Previous studies have shown that 54 Cr is heterogeneously distributed in Solar System materials, including chondrites, differentiated stony and iron meteorites [1]. Each meteorite group has its characteristic 54 Cr signature. Even though the 54 Cr anomalies are widely thought to be nucleosynthetic in origin, the nucleosynthetic process responsible for its production and the cause ...
BACKGROUND The primary objective of this phase 2 study was to assess the objective response rate (complete response [CR] + partial responses [PR]), by Response Evaluation Criteria in Solid Tumors, of PF-3512676, a CpG oligodeoxynucleotide, alone in 2 doses or in combination with dacarbazine (DTIC) in patients with unresectable stage IIIB/C or stage IV malignant melanoma, with the aim of selecti...
The effects of chromium picolinate (CrPic) supplementation and resistance training (RT) on skeletal muscle size, strength, and power and whole body composition were examined in 18 men (age range 56-69 yr). The men were randomly assigned (double-blind) to groups (n = 9) that consumed either 17.8 micromol Cr/day (924 microg Cr/day) as CrPic or a low-Cr placebo for 12 wk while participating twice ...
We have calculated the cosmic ray (CR) acceleration at young remnants from Type Ia supernovae expanding into a uniform interstellar medium (ISM). Adopting quasi-parallel magnetic fields, gasdynamic equations and the diffusion convection equation for the particle distribution function are solved in a comoving spherical grid which expands with the shock. Bohm-type diffusion due to self-excited Al...
Caloric restriction (CR) attenuates age-related muscle loss. However, the underlying mechanism responsible for this attenuation is not fully understood. This study evaluated the role of energy metabolism in the CR-induced attenuation of muscle loss. The aims of this study were twofold: 1) to evaluate the effect of CR on energy metabolism and determine its relationship with muscle mass, and 2) t...
