Magnetic properties and domain-wall motion in single-crystal BaFe10.2Sn0.74Co0.66O19

The magnetic properties of BaFe12O19 and BaFe10.2Sn0.74Co0.66O19 single crystals have been investigated in the temperature range (1.8 to 320 K) with a varying field from -5 to +5 T applied parallel and perpendicular to the c axis. Low-temperature magnetic relaxation, which is ascribed to the domain-wall motion, was performed between 1.8 and 15 K. The relaxation of magnetization exhibits a linear dependence on logarithmic time. The magnetic viscosity extracted from the relaxation data, decreases linearly as temperature goes down, which may correspond to the thermal depinning of domain walls. Below 2.5 K, the viscosity begins to deviate from the linear dependence on temperature, tending to be temperature independent. The near temperature independence of viscosity suggests the existence of quantum tunneling of antiferromagnetic domain wall in this temperature range.

Immunogenicity and safety of an intradermal boosting strategy for vaccination against influenza in lung transplant recipients.

The immunogenicity of influenza vaccine is suboptimal in lung transplant recipients. Use of a booster dose and vaccine delivery by the intradermal rather than intramuscular route may improve response. We prospectively evaluated the immunogenicity and safety of a 2-dose boosting strategy of influenza vaccine. Sixty lung transplant recipients received a standard intramuscular injection of the 2006-2007 inactivated influenza vaccine, followed 4 weeks later by an intradermal booster of the same vaccine. Immunogenicity was assessed by measurement of geometric mean titer of antibodies after both the intramuscular injection and the intradermal booster. Vaccine response was defined as 4-fold or higher increase of antibody titers to at least one vaccine antigen. Thirty-eight out of 60 patients (63%) had a response after intramuscular vaccination. Geometric mean titers increased for all three vaccine antigens following the first dose (p < 0.001). However, no significant increases in titer were observed after the booster dose for all three antigens. Among nonresponders, 3/22 (13.6%) additional patients responded after the intradermal booster (p = 0.14). The use of basiliximab was associated with a positive response (p = 0.024). After a single standard dose of influenza vaccine, a booster dose given by intradermal injection did not significantly improve vaccine immunogenicity in lung transplant recipients.

Changes in Aortic Pulse Wave Velocity in Hypertensive Postmenopausal Women: Comparison Between a Calcium Channel Blocker vs Angiotensin Receptor Blocker Regimen.

J Clin Hypertens (Greenwich). 2012;14:773-778. ©2012 Wiley Periodicals, Inc. Postmenopausal women are at greater risk for hypertension-related cardiovascular disease. Antihypertensive therapy may help alleviate arterial stiffness that represents a potential modifiable risk factor of hypertension. This randomized controlled study investigated the difference between an angiotensin receptor blocker and a calcium channel blocker in reducing arterial stiffness. Overall, 125 postmenopausal hypertensive women (age, 61.4±6 years; systolic blood pressure/diastolic blood pressure [SBP/DBP], 158±11/92±9 mm Hg) were randomized to valsartan 320 mg±hydrochlorothiazide (HCTZ) (n=63) or amlodipine 10 mg±HCTZ (n=62). The primary outcome was carotid-to-femoral pulse wave velocity (PWV) changes after 38 weeks of treatment. Both treatments lowered peripheral blood pressure (BP) (-22.9/-10.9 mm Hg for valsartan and -25.2/-11.7 mm Hg for amlodipine, P=not significant) and central BP (-15.7/-7.6 mm Hg for valsartan and -19.2/-10.3 mm Hg for amlodipine, P<.05 for central DBP). Both treatments similarly reduced the carotid-femoral PWV (-1.9 vs -1.7 m/s; P=not significant). Amlodipine was associated with a higher incidence of peripheral edema compared with the valsartan group (77% vs 14%, P<.001). BP lowering in postmenopausal women led to a reduction in arterial stiffness as assessed by PWV measurement. Both regimens reduced PWV to a similar degree after 38 weeks of treatment despite differences in central BP lowering, suggesting that the effect of valsartan on PWV is mediated through nonhemodynamic effects.

Modelización Gravimétrica 3D del diapiro de Cardona, Cuenca del Ebro (NE de España)

En este trabajo se presentan los resultados derivados de la interpretacón de 320 estaciones gravimétricas realizadas sobre el diapiro de Cardona con el objetivo de obtener información sobre su geometría tridimensional. Para obtener una distribución tridimensional de la masa salina que explique las anomalías observadas se ha aplicado un método iterativo de ajustes sucesivos basado en un algoritmo de inversión automática. Esta metodología ha mostrado ser muy rápida, fácil de usar y con suficiente poder de resolución para perfilar no sólo la geometría del cuerpo salino, sino también la de estructuras similares. El diapiro salino de Cardona presenta un mínimo gravimétrico relacionado con el anticlinal de Pins-Cardona que se prolonga hacia el SW. El análisis cualitativo de la anomalía residual permite apreciar que el diapiro muestra una cierta vergencia hacia sur con un flanco sureste subvertical y un flanco noroeste con pendientes más suaves.

Produção de cordeiros em pastagem de azevém e trevo-branco sob diferentes níveis de resíduos de forragem

Na presente pesquisa, objetivou-se analisar os efeitos de diferentes níveis de resíduos de forragem na produção de cordeiros. O experimento foi estabelecido em Tupanciretã, região do Planalto Médio do Estado do Rio Grande do Sul, em uma pastagem de azevém cv. Estanzuela 284 (Lolium multiflorum Lam) + trevo-branco cv. Yi (Trifolium repens L.), submetida a diferentes níveis de resíduo de matéria seca (RMS). O delineamento experimental utilizado foi o completamente casualizado, estudando-se os níveis de RMS mantidos na pastagem de 1.119, 1.320, 1.477, 1.695, 2.146, 2.166, 2.410 e 2.483 kg de matéria seca por hectare (MS/ha). O período experimental foi de 30/09 a 08/12/1992 e os animais utilizados foram cordeiros cruza Ile de France x Corriedale desmamados aos 80 dias. Foram avaliados o ganho de peso médio diário (GMD), ganho de peso vivo/ha (GPV/ha), carga animal, animais dia/ha e a eficiência de conversão de MS em kg de peso vivo de cordeiros. Os resultados obtidos mostraram uma relação linear positiva entre o GMD e GPV/ha com o aumento nos níveis de RMS/ha, observando-se nos níveis de RMS superiores a 2.400 kg um GMD de 0,12 kg/cordeiro/dia e um GPV/ha médio de 497 kg. Não houve relação quanto à carga animal e animais.dia/ha; verificou-se uma relação linear negativa entre a eficiência de conversão de MS com os níveis de RMS estudados. Os resultados demonstram o efeito dos níveis de RMS na resposta animal.

Cytokines and T-cell homeostasis.

Homeostasis of T cells can be defined as the ability of the immune system to maintain normal T-cell counts and to restore T-cell numbers following T-cell depletion or expansion. These processes are governed by extrinsic signals, most notably cytokines. Two members of the common gamma chain family of cytokines, interleukin (IL)-7 and IL-15, are central to homeostatic proliferation and survival of mature CD4(+) and CD8(+) T cells. Recent evidence suggests that other cytokines, including IL-2, IL-10, IL-12, interferons and TGF-beta, as well as the transcription factors T-bet and eomesodermin all play important but different roles at distinct stages of T-cell homeostasis.
