Histomorphometric analysis of.histologic sections of.normal and diseased bone samples,such as healing allograf.s and f.actures,is widely used in bone ***,the utility of.traditional semi-automated methods is limited because they are labor-intensive and can have high interobserver variability depending upon the parameters being assessed,and primary data cannot be re-analyzed *** histomorphometry has long been recognized as a solution f.r these issues,and recently has become more f.asible with the development of.digital whole slide imaging and computerized image analysis systems that can interact with digital ***,we describe the development and validation of.an automated application（algorithm）using Visiopharm＇s image analysis system to quantif. newly f.rmed bone,cartilage,and f.brous tissue in healing murine f.moral allograf.s in high-quality digital images of.H＆E/alcian blue-stained decalcif.ed histologic *** validate this algorithm,we compared the results obtained independently using OsteoMeasureTM and Visiopharm image analysis *** intraclass correlation coef.icient between Visiopharm and OsteoMeasure was very close to one f.r all tissue elements tested,indicating nearly perf.ct reproducibility across *** new algorithm represents an accurate and labor-ef.icient method to quantif. bone,cartilage,and f.brous tissue in healing mouse allograf.s.

In present research, a novel extractant system (D2EHPA + naphthenic acid + pyridine- ester) was used to purif. cobalt anolyte and a simulated industrial production were carried out. This novel extraction system can extract Cu and/or Ni against Co f.om chloride medium solutions at pH range of.2.5-4.5. About 2g/l nickel and 0.2g/l copper were removed f.om the cobalt chloride anolyte containing about 100g/l cobalt and 200g/l chloride ions respectively, the raf.inate contains nickel and copper less than 0.03g/l and 0.0003g/l respectively and can be used to electrolyze high-purity cobalt. About 5.5t cobalt anolyte was purif.ed in the simulation industrial experiment and kilogram quantities of.cobalt of.99.98% purity and about 95% recovery have been produced.

Graphene has been considered as a promising material which may f.nd applications in the THz science. In this work, we numerically investigate tunable photonic crystals in the THz range based on stacked graphene/dielelctric layers, a complex pole-residue pair model is used to f.nd the ef.ective permittivity of.graphene, which could be easily incorporated into the f.nite-dif.erence time domain （f.TD） algorithm. Two dif.erent schemes of.photonic crystal used f.r extending the bandgap have been simulated through this f.TD technique.

In this work, three widely used commercial Zn alloys （ZA4-1, ZA4-3, ZA6-1 ） were purchased and pre- pared by hot extrusion at 200℃. The microstructure, mechanical properties, corrosion behaviors, biocompatibility and hemocompatibility of.Zn alloys were studied with pure Zn as control, Commercial Zn alloys demonstrated increased strength and superb elongation compared with pure Zn. Accelerated corrosion rates and unif.rm corrosion morphologies were observed in terms of.commercial Zn alloys due to galvanic ef.ects between Zn matrix and α-Al phases. 100% extracts of.ZA4-1 and ZA6-1 alloys showed mild cytotoxicity while 50% extracts of.all samples displayed good biocompatibility. Retardant cell cycle and inhibited stress f.bers expression were observed induced by high concentration of.Zn^2＋ releasing during corrosion. The hemolysis ratios of.Zn alloys were lower than 1% while the adhered platelets showed slightly activated morphologies. In general, commercial Zn alloys possess promising mechanical properties, appropriate corrosion rates, signif.cantly improved biocompatibility and good hemocompatibility in comparison to pure Zn. It is f.asible to develop biodegradable metals based on commercial Zn alloys.

近几年来,HIV感染的治疗有了显著的改善,发病率和死亡率明显下降。在临床研究中,欧洲-澳洲的“Delta”研究和美国的“ACTG 175”研究均证实联合治疗优于单一疗法,因此现在联合治疗成为了标准疗法。某一种药物的单一疗法已被淘汰。
