Based on the mean field multiple-sublattices model, the estimated T-C is about 114 K for M = Ti and 1270 K for M Fe, calculated with the experimental lattice constant, in good agreement with the experimental values (128 K and 1093 K for M Ti and Fe, respectively). With increasing lattice constant, a, from 95% to 105% of the experimental value (a(exp).),

the moment per formula unit m(f.u.) changes from 0.43 mu(B) to 1.0 mu(B) and TC increases from 27 K to 142 K in Co2TiGa. However, m(f.u.) increases slightly from 4.98 mu B to 5.40 mu B while T-C decreases from 1330 K to 1190 K with increasing a PD-1/PD-L1 Inhibitor 3 mw from 95% to 105% of aexp : in Co2FeGa. These different volume dependences of T-C are ascribed to the weak ferromagnetism in Co2TiGa and the strong ferromagnetism in Co2FeGa. (C) 2011 American Institute of Physics.

“The authors used clock-drawing performance to assess cognition and predict inpatient rehabilitation outcomes among persons with traumatic brain injury. Clock-drawing performance, as assessed with the Clock Drawing Interpretation Scale,

predicts rehabilitation length of stay as well as Functional Independence Measure scores at the time selleck of neurobehavioral assessment and rehabilitation discharge. (The Journal of Neuropsychiatry and Clinical Neurosciences 2011; 23:449-453)”
“This study was carried out to determine if exposure to hot environmental temperatures had a direct, detrimental effect on sperm quality. For this the effect of whole-body heat exposure on epididymal spermatozoa of laboratory mice was investigated. C57BL/6 mice (n = 7) were housed in a microclimate Batimastat mouse chamber at 37 degrees C-38 degrees C for 8 h per day for three consecutive days, while control mice (n = 7) were kept at 23 degrees C-24 degrees C. Cauda epididymal spermatozoa were obtained 16 h after the last heat treatment. The results showed that sperm numbers were similar in the two groups (P = 0.23), but after heat treatment, a significant reduction

in the percentage of motile sperm was present (P < 0.0001). Membrane changes of the spermatozoa were investigated by staining with phycoerythrin (PE)-conjugated Annexin V, which detects exteriorization of phosphotidylserine from the inner to the outer leaflet of the sperm plasma membrane, and 7-aminoactinomycin D (7-AAD), which binds to the sperm nucleus when the plasma membrane is damaged. The percentage of spermatozoa showing positive staining with Annexin V-PE or 7-AAD or both, was significantly higher (P < 0.05) in heat-exposed mice compared with controls. These results show that whole-body heat exposure to 37 degrees C-38 degrees C induces membrane changes in the epididymal spermatozoa of mice, which may lead to apoptosis.”
