Binary bright Ni-Co alloy films were electro- deposited on titanium in the chloride-sulfate electrolytes. The influences of Co2＋ concentration, current density, and temperature on the Ni-Co alloy films electrodeposition were investigated. The films were analyzed by scanning electron microscope （SEM）, energy dispersive spectros- copy （EDS）, and X-ray diffraction （XRD）. Cathodic polarization for Ni-Co codeposition was performed on Ti working electrodes. With the increase of Co2＋ concentra- tion, the Ni content in the films decreases and the current efficiency increases slightly. The Ni content increases with the increase of temperature, while it decreases with the increase of current density to a minimum and then increases. The cathodic reduction peak potential is mea- sured to be -1.34 V. Anomalous deposition is found to occur in the Ni-Co codeposition. The SEM of Ni-Co alloy films shows that hydroxide particles are not present on the surface and fine grain, compact, smooth, and bright Ni--Co alloy films are obtained. The XRD result indicates that the deposited Ni-Co alloy film is Ni-solid solution with a face- centered cubic in structure.

The experiment was conducted to study the specific expression of HSP70 caused by heat shock, HSP70 purification and the characteristics of coalescence with antigenic peptide in the formation of the complex. Sixty healthy 6-week-old male Wulong geese were selected and randomly divided into three groups. The control group was slaughtered without heat treatment. Treatment group 1 was shocked with an acute heat treatment at （42 ± 1）℃ for 5 h before they were immediately slaughtered. Treatment group 2 was kept for 12 h after the heat treatment under normal conditions in order to recover and was then slaughtered. Cardiac tissue was taken in order to make paraffin sections for the immunohistochemistry experiment and the liver tissue was used to purify HSP70. The geese heart HSP70 expression differences in the three groups were determined and at the same time the experiments of HSP70 purification and appraisal in the liver tissue were carried on. HSP70 purification and synthesis of HBV PreS1 multi-peptides unified the complex, which was determined by bi-specific antibody enzyme-linked immune sandwich assay. The results indicated that widespread HSP70 positive pellets in the cardiac muscle were found under hot shock conditions. HSP70 expression in the treatment group 1 was centered in the karyotheca and its periphery, but in treatment group 2, it was centered in the surrounding cell membrane. The HSP70 purification could be obtained through two sets of purification plans; both the synthesis peptide and the HSP70 purification form the complex under certain conditions. The double antibody sandwich ELISA technique was applied to detect if the complex had been formed. Positive results showed that the complex was formed. The specific expression of HSP70 under heat shock shifted with time, suggesting that HSP70 possibly had some function in cell protection. High-purity HSP70 protein can be obtained under low-pressure chromatography conditions, and in comparison with each other, it

Despite considerable research underscoring the importance of carbohydrate intake in relation to the risk of type 2 diabetes(T2D), a comprehensive assessment of this relationship is currently lacking. We aimed to examine the associations of various types and food sources of dietary carbohydrate intake with the risk of T2D, to evaluate potential effect modification by other factors, including genetic susceptibility,and to explore the potential mediators for such associations. The present study included 161,872 participants of the UK Biobank who were free of prevalent cancer, cardiovascular disease, or diabetes, and had at least one validated 24-h dietary recall assessment. Multivariableadjusted age-stratified Cox proportional hazard regression models were applied to estimate hazard ratios(HRs) and 95% confidence intervals(CI) for the associations of various types and food sources of dietary carbohydrate intake with risk of T2D. During a median follow-up of13.6 years, 4,176 incident cases of T2D were identified. In the multivariable-adjusted models, a greater intake of fiber, carbohydrates from whole grains, and carbohydrates from non-starchy vegetables was significantly associated with a lower risk of T2D(highest vs. lowest quantile, HR [95% CI]=0.70 [0.62–0.79], 0.74 [0.67–0.82], and 0.83 [0.75–0.92], respectively, all P for trend <0.005). In contrast, a higher intake of starch and carbohydrate from starchy vegetables was associated with an increased risk of T2D(highest vs. lowest quantile, HR [95%CI]=1.31 [1.16–1.48] and 1.19 [1.09–1.31], respectively, both P for trend <0.005). Replacing one serving of refined grains or starchy vegetables with an equal amount of whole grains or non-starchy vegetables was associated with 4% to 10% lower risk of T2D(all P values <0.001).The observed associations were generally similar across population subgroups, including individuals with different genetic susceptibility to T2D.

Background The temporal response to off-pump anteroapical aneurysm plication has not been well defined. We have evaluated the long-term clinical and functional results of this technique and compared the efficacy with the patch modeling repair. Methods From March 2005 to May 2010, 163 （115 men and 48 women） consecutive patients were operated on for post-infarction left ventricular aneurysm （LVA）, 54 patients underwent patch remodeling （group A） and 109 patients underwent off-pump anteroapical aneurysm plication repair （group B）. All patients had simultaneous coronary revascularization, other operative procedures included septoplasty in eight and ablation of ventricular tachycardia in six. Follow-up ranged from 1 to 5 years, short-term and mid-term outcomes, including complications, cardiac function, and mortality, were assessed. Results Early mortality was 1.8% for all patients （group A 1 death vs. group B 2 deaths, not significant （NS））. Peri-operative support included intraaortic balloon pumping in 16 （9.8%）, （group A 6 patients vs. group B 10 patients, NS） and inotropic drugs in 84 （51.5%）, （group A 34 vs. group B 50, NS）. During a mean follow-up of （3.7±0.8） years, eight patients died, with four due to cardiac-related causes. No patient required transplantation, and two required use of an implantable cardioverter-defibrillator for ventricular tachycardia. Survival at 1 and 5 years was 95% and 86%, respectively. It did not differ significantly between group A and group B. Functional class improved from 2.90±0.59 to 1.65±0.54 among the mid-term survivors （P 〈0.001）, with no significant difference between the two groups. Pre-operative risk factors for mortality or poor function were ejection fraction （EF）〈0.35 （OR=7.9, 95% CI 1.6-40.0）; congestive heart failure （CHF）（OR=4.4, 95% CI 1.0-19.0）; end-systolic volume index （ESVI）〉80 ml/m2 （OR=3.7, 95% CI 1.0-14.0）; and advanced age 〉70 years （OR=2.4, 95% CI 1.0-12.0）.
