“The effect of Si and Ga substitutions on the magnetic and the magnetocaloric properties in Heusler based system Ni(46)Co(4)Mn(38)Sb(12-x)Z(x) (Z = Si and Ga) has been studied. From the M(T) plots it is found that Si substitution stabilizes the austenite phase, whereas Ga substitution stabilizes the martensite phase. Strong metamagnetic behavior is observed in the M(H) isotherms for Si = 0.75 and 1, whereas such a behavior is absent in the Ga substituted alloys. Associated with magneto-structural transition,

a large magnetocaloric effect (MCE) of 58 and 70 J/kg K is observed for x = 0.75 and 1, respectively, in the case of Si. Though the MCE observed in x = 0.5 and 1 in the case of Ga is much lower, the MCE peak is found

to be quite broad. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3554219]“
“PURPOSE: To assess selleck products the risk for intraoperative and postoperative bleeding associated with antiplatelet and/or anticoagulant treatment in patients having uneventful phacoemulsification.

SETTING: Kokura Memorial Hospital, Kitakyusyu, Japan.

METHODS: In a nonrandomized case series, consecutive patients had phacoemulsification and intraocular lens implantation BX-795 inhibitor under sub-Tenon anesthesia. All patients were on warfarin, acetylsalicylic acid (aspirin) therapy, or both. Patients discontinued therapy 1 week before surgery (discontinuation group) or continued the therapeutic regimen until ACY-738 the time of surgery

(maintenance group).

RESULTS: The discontinuation group comprised 182 patients and the maintenance group, 173 patients. There was no significant difference between the 2 groups in the mean prothrombin time international normalized ratio in patients taking warfarin (P = .6). Although there was no significant intraoperative bleeding in any case, 47 eyes (16.5%) in the maintenance group and 31 eyes (10.8%) in the discontinuation group had a subconjunctival hemorrhage postoperatively (P = .0309). Minor postoperative ocular bleeding occurred in 11 eyes (4.0%) in the maintenance group and 7 eyes (2.5%) in the discontinuation group (P = .4). During the 1-month postoperative period, the mean change in corrected distance visual acuity was -0.462 logMAR +/- 0.331 (SD) in the maintenance group and -0.434 +/- 0.318 logMAR in the discontinuation group (P = .3).

CONCLUSIONS: Patients taking warfarin, aspirin, or both up to the time of phacoemulsification had a significantly higher incidence of subconjunctival hemorrhage than those who discontinued therapy. There was no significant difference between the 2 groups in the incidence of intraoperative and postoperative complications or in visual improvement.”
“Aluminium (Al) stress is an important factor limiting crop yields in acid soils. Despite this, very little is known about the mechanisms of resistance to this stress in woody plants.
