目的:探讨辛伐他汀对大鼠心肌缺血再灌注后细胞凋亡及线粒体融合素2(Mitofusin 2,Mfn2)表达的影响。方法:选取32只Sprague-Dawley(SD)大鼠,随机分为假手术组、缺血再灌注模型组(模型组)、5 mg辛伐他汀组、10 mg辛伐他汀组,每组8只。5 mg辛伐他汀组、10 mg辛伐他汀组分别于术前7 d开始给予5 mg/(kg·d)、10 mg/(kg·d)的辛伐他汀灌胃,假手术组、模型组均给予等量蒸馏水灌胃。采用结扎左前降支法建立大鼠心肌缺血再灌注损伤模型。各组于造模后3 h剪取心脏组织,采用TUNEL法检测心肌细胞凋亡,Western Blot法检测p-Akt的表达,免疫组织化学法检测Mfn2的表达。结果 :与假手术组相比较,模型组心肌细胞凋亡指数、Mfn2的表达明显升高,p-Akt的表达显著降低(均pp-Akt的表达显著升高(均pp<0.05)。结论:辛伐他汀可有效抑制心肌缺血再灌注损伤后的心肌细胞凋亡,抑制Mfn2表达是其可能作用机制。

Mixed Mg-Cr Nano ferrites having the compositional formula MgCrxFe2-xO4 (where x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0) were synthesized using Citrate-Gel auto combustion method. Structural characterization was carried out by XRD Analysis which confirmed the formation of single phase cubic spinel structure without any impurity peak. The dielectric properties such as Dielectric constant (ε'), Dielectric Loss tangent (tan δ) and AC conductivity (σAC) of Mg-Cr nano ferrites were studied at room temperature in the frequency range of 2 Hz - 2 MHz using Agilent E4980A precision LCR meter. The dielectric constant, loss tangent and AC conductivity shows a normal behavior with frequency. A qulitative explanation is given for composition and frequency dependance of the dielectric constant, dielectric loss tangent and AC conductivity of the nano ferrite. The loss tangent for the synthesized samples was found to be decreased from 0.09 to 0.054 in higher frequency region showing the potential applications of these materials in high frequency micro wave devices. On the basis of these results the explanation of dielectric mechanism in Mg-Cr ferrites is suggested.

Co-Cr nano-ferrites, having the chemical formula CoCrxFe2-xO4 (where x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0), were synthesized by the Citrate-gel auto combustion method. Synthesized powders were sintered at 500°C for 4 hours in an air and were characterized by XRD, SEM and EDS. XRD analysis showed cubic spinel structure of the ferrites and the crystallite sizes (D) were found in the range of 6 - 12 nm. The values of lattice parameter (a) decreased and X-ray density (dx) increased with the increase of Cr content. Scanning Electron Microscopic (SEM) studies revealed nano crystalline nature of the samples. An elemental composition of the samples was studied by Energy Dispersive Spectroscopy (EDS). The observed results can be explained on the basis of composition and crystal size.

AIM: To determine if efforts to improve antiretroviral therapy(ART) adherence minimizes the negative impact of depression on human immunodeficiency virus(HIV) outcomes. METHODS: A cross-sectional study of a clinic-based cohort of 158 HIV seropositive(HIV+) African Americans screened for major depressive disorder(MDD) in 2012. CD4 T lymphocyte(CD4+) counts were obtained from these individuals. Self-report on adherence to ART was determined from questionnaire administered during clinic visits. The primary outcome measure was conditional odds of having a poorer CD4+ count(pressant-treated or untreated MDD subjects was examined controlling for self-reported adherence and other potential confounders. RESULTS: Out of 147 individuals with available CD4+ T lymphocyte data, 31% had CD4+ count ported poor ART adherence. As expected the group with > 350 cells/mm^3 CD4+ T lymphocyte endorsed significantly greater ART adherence compared to the group with phocyte count(p prevalence of MDD was 39.5% and 66% of individuals with MDD took antidepressants. poor CD4+ T lymphocyte count was associated with poor ART adherence and MDD. Adjusting for ART adherence, age, sex and education, which were potential confounders, the association between MDD and poor CD4+ T lymphocyte remained significant only in the untreated MDD ***: Therefore, CD4+ count could be a clinical marker of untreated depression in HIV+. Also, mental health care may be relevant to primary care of HIV+ patients.
