1新型PEO/纳米结构ZrO_2镁合金涂层的抗菌活性及腐蚀行为(英文)显示文摘为了增强镁合金的耐腐蚀性和抗菌活性,先采用等离子体电解氧化(PEO)在镁合金上制备一层结合层,再用空气等离子喷涂(APS)制备纳米结构ZrO_2表面涂层。采用电化学试验研究涂层样品的腐蚀行为,采用琼脂扩散法对其进行大肠杆菌病原菌抑菌活性评价,并与无涂层样品进行对比。与PEO涂层和无涂层镁合金相比,PEO/纳米ZrO_2涂层样品的腐蚀电流密度最低,电荷传递阻力最高,相位角和阻抗模量最高。PEO结合涂层被纳米ZrO_2表面涂层完全密封,能够显著延缓侵蚀性离子向镁合金表面迁移,显著提高镁合金在模拟体液(SBF)中的耐蚀性。此外,PEO/纳米ZrO_2涂层的抗菌活性也高于PEO涂层和无涂层镁合金,这是由于ZrO_2纳米颗粒通过作用于细胞膜而降低了大肠杆菌的生长速率。Mohammadreza DAROONPARVAR Muhamad Azizi MAT YAJID Rajeev KUMAR GUPTA Noordin MOHD YUSOF Hamid Reza BAKHSHESHI-RAD Hamidreza GHANDVAR Ehsan GHASEMI 2018Transactions of Nonferrous Metals Society of China2018,28,8:10
2Y chromosome microdeletions in azoospermic patients with Klinefelter's syndrome显示文摘瞄准:与 Klinefelter 的症候群(KFS ) 在 azoospermic 病人学习 Y 微删除的出现。方法:血和精液样品与 KFS 从 azoospermic 病人被收集(n = 14 ) 并且证明富饶的人的一个控制组(n = 13 ) 。精液分析根据世界卫生组织被做() 指南。血样品为 karyotyping,荧光灯的原位杂交(鱼) 和由放射性免疫测定刺激荷尔蒙(FSH ) 的血浆滤泡的测量被处理。决定 Y 微删除, 16 顺序的聚合酶链反应(PCR ) 标注了地点(圣) ,三基因(DFFRY, XKRY 和 RBM1Y ) 在孤立的 genomic DNA 上被执行。阴囊的好针渴望细胞学(FNAC ) 在选择情况中被做。结果:跨越一个 and AZFb 部位与 KFS 在 14 个 azoospermic 病人中的四个被发现的精子缺乏因素(AZF ) 的 Y 微删除。染色质组型和鱼分析表明显示出 Y 微删除的四个盒子,三个盒子有一 47, XXY/46, XY 染色体的模式和一个盒子有一 46, XY/47, XXY/48, XXXY/48, XXYY 染色体的模式。有 Y 微删除的一件样品的阴囊的 FNAC 揭示了形态学的 Sertoli 房间唯一的类型。然而,没有 Y 微删除在任何 13 个肥沃的人被观察。有 KFS 的所有病人提高了血浆 FSH 层次。结论:有 KFS 的病人可以怀有 Y 微删除并且为这些屏蔽应该是他们的诊断病情的检查的部分,特别地在那些考虑帮助了繁殖技术。Anurag Mitra Rima Dada Rajeev Kumar Narmada Prasad Gupta Kiran Kucheria Satish Kumar Gupta 2006Asian Journal of Andrology2006,8,1:8
3Higher frequency of Yq microdeletions in sperm DNA as compared to DNA isolated from blood显示文摘瞄准:决定删除的 Yq 微删除频率和 loci 是否在不同胚胎学的起源的二纸巾(血和精子) 是类似的。方法:现在的学习包括了 52 个不肥沃的 oligozoospermic 盒子。在每种情况中, DNA 从血和精子被孤立,微删除分析从 genomic DNA 被做的聚合酶链反应(PCR ) 从两个孤立纸巾。PCR 产品在 1.8% 统帅玫瑰胶化上被分析。发现否定的 PCR 扩大被重复至少三次证实一个给定的标记的删除。结果:仅仅 1 个盒子在血 DNA 怀有微删除,而 4 个盒子在精子 DNA 怀有微删除。结论:Yq 微删除的频率作为与血相比在细菌房间是更高的。为帮助繁殖生产技术(艺术) 作为不肥沃的夫妇的多数抉择, Yq 微删除从细菌房间屏蔽是重要的理解不孕的基因基础,提供全面建议和大多数改编治疗学给不肥沃的夫妇。Rima Dada Rakesh Kumar M.

4在在印度的心血管的风险因素的地区性的变化: 印度心手表显示文摘 Cardiovascular disease(CVD) is an important cause of mortality and morbidity in India.Mortality statistics and morbidity surveys indicate substantial regional variations in CVD prevalence and mortality rates.Data from the Registrar General of India reported greater ageadjusted cardiovascular mortality in southern and eastern states of the country.Coronary heart disease(CHD) mortality is greater in south India while stroke is more common in the eastern Indian states.CHD prevalence is higher in urban Indian populations while stroke mortality is similar in urban and rural regions.Case-control studies in India have identified that the common major risk factors account for more than 90% of incident myocardial infarctions and stroke.The case-control INTERHEART and INTERSTROKE studies reported that hypertension,lipid abnormalities,smoking,obesity,diabetes,sedentary lifestyle,low fruit and vegetable intake,and psychosocial stress are as important in India as in other populations of the world.Individual studies have reported that there are substantial regional variations in risk factors in India.At a macro-level these regional variations in risk factors explain some of the regional differences in CVD mortality.However,there is need to study the prevalence of multiple cardiovascular risk factors in different regions of India and to correlate them with variations in CVD mortality using a uniform protocol.There is also a need to determine the 'causes of the causes' or fundamental determinants of these risk factors.The India Heart Watch study has been designed to study socioeconomic,anthropometric and biochemical risk factors in urban populations in different regions of the country in order to identify regional differences.Rajeev Gupta Soneil Guptha Krishna Kumar Sharma Arvind Gupta Prakash Deedwania 2012World Journal of Cardiology2012,4,4:3
5Study of morphologic variability of incudostapedial angle and its relation with temporal bone pneumatization显示文摘Introduction:Optimal sound transmission across the ossicular chain is dependent on the appropriate alignment of the middle ear ossicles.Incudostapedial joint(ISJ)is conventionally considered to be at right angle.Objective:We intended to study the ISJ anatomy and the impact of temporal bone pneumatization on the same.Methods:In a cadaveric study comprising of 47 human temporal bones,canal wall down mastoidectomy was carried out under microscopic guidance keeping the ossicular chain intact.The morphology of ISJ was recorded and analysed with respect to the pneumatization status of the temporal bone.The data analysis was performed using statistical software Stata version 12.0.Results:The mean ISJ angle for the 47 bones was 90.5^0(SD-15^0;range:54^0-122^0).The mean angle in well pneumatized bones was 93.7^0(SD-16.5;Range:54°-122^0)and in sclerotic mastoids was 88.7^0(SD-14;Range:68°-118^0).The difference in the ISJ angle in these two conditions was not statistically significant(p=0.27).The mean angle was found to be significantly more obtuse in the cases with partially eroded ISJ(111.4^0{SD-8.8;range:100.3^0-221.9^0};p=0.0001)and in the cases with an‘adherent/tilted morphology’of the stapes suprastructure with the promontory(mean-95.8^0(SD-13.8;range:70.7^0-120.4^0);p-<0.00001).Conclusion:The ISJ angle shows considerable variations.This variability needs to be taken into account when undertaking middle ear reconstructive procedures,specifically the ones involving the stapes footplate.The mastoid pneumatization does not appear to have an impact on the ISJ angle.Anup Singh David Victor Kumar Irugu Rajeev Kumar Hitesh Verma Anandita Gupta Abha Kumari 2020Journal of Otology2020,15,2:3
