| 1 | 激光剥蚀信号在线平滑和去汞装置:原位微区铅同位素准确分析利器显示文摘激光原位微区分析可在微观尺度上完成样品的元素定量分析或同位素组成测定,为研究成岩、成矿物质来源和追踪地壳与地幔演化历史提供了独特的观察视野。但是,激光剥蚀等离子体质谱的一些缺陷阻碍了地质样品的高精度、高空间分辨率分析,比如:剥蚀池的位置效应、低剥蚀速率下信号波动影响、激光剥蚀脉动式信号导致的光谱螺纹效应、高频激光剥蚀造成的元素分馏效应等。为此,一些学者设计了不同规格和样式的激光剥蚀信号平滑装置来克服这些问题。但是,这些信号平滑装置普遍还存在气体吹扫时间过长和降低激光剥蚀信号灵敏度等问题。因此,研制新型的信号平滑装置对改善LA—ICP—MS的数据质量具有重要的意义。 | Hu Z Zhang W Liu Y Gao S Li M Zong K Chen H Hu S 刘勇胜 | 2015 | 矿物岩石地球化学通报2015,34,4: | 114 |

| 4 | Role of live microbial feed supplements with reference to anaerobic fungi in ruminant productivity: A review显示文摘To keep the concept of a safe food supply to the consumers, animal feed industries world over are showing an increasing interest in the direct-fed microbials(DFM) for improved animal performance in terms of growth or productivity. This becomes all the more essential in a situation, where a number of the residues of antibiotics and/or other growth stimulants reach in milk and meat with a number of associated potential risks for the consumers. Hence, in the absence of growth stimulants, a positive manipulation of the rumen microbial ecosystem to enhance the feedstuff utilization for improved production efficiency by ruminants has become of much interest to the researchers and entrepreneurs. A few genera of live microbes(i.e., bacteria, fungi and yeasts in different types of formulations from paste to powder) are infrequently used as DFM for the domestic ruminants. These DFM products are live microbial feed supplements containing naturally occurring microbes in the rumen. Among different DFM possibilities, anaerobic rumen fungi(ARF) based additives have been found to improve ruminant productivity consistently during feeding trials. Administration of ARF during the few trials conducted, led to the increased weight gain, milk production, and total tract digestibility of feed components in ruminants. Anaerobic fungi in the rumen display very strong cell-wall degrading cellulolytic and xylanolytic activities through rhizoid development, resulting in the physical disruption of feed structure paving the way for bacterial action. Significant improvements in the fiber digestibility were found to coincide with increases in ARF in the rumen indicating their role. Most of the researches based on DFM have indicated a positive response in nutrient digestion and methane reducing potential during in vivo and/or in vitro supplementation of ARF as DFM. Therefore, DFM especially ARF will gain popularity but it is necessary that all the strains are thoroughly studied for their beneficial properties to have a confirmed ‘generally regarded as safe' status for ruminants. | Anil K Puniya Abdelfattah Z M Salem Sanjay Kumar Sumit S Dagar Gareth W Griffith Monica Puniya Sreenivas R Ravella Nikhil Kumar Tejpal Dhewa Ravinder Kumar | 2015 | Journal of Integrative Agriculture2015,14,3: | 17 |
| 5 | Factors affecting healing after arthroscopic rotator cuff repair显示文摘Rotator cuff repair has been shown to have good longterm results. Unfortunately, a significant proportion of repairs still fail to heal. Many factors, both patient and surgeon related, can influence healing after repair. Older age, larger tear size, worse muscle quality, greater muscle-tendon unit retraction, smoking, osteoporosis, diabetes and hypercholesterolemia have all shown to negatively influence tendon healing. Surgeon related factors that can influence healing include repair construct-single vs double row, rehabilitation, and biologics including platelet rich plasma and mesenchymalstem cells. Double-row repairs are biomechanically stronger and have better healing rates compared with single-row repairs although clinical outcomes are equivalent between both constructs. Slower, less aggressive rehabilitation programs have demonstrated improved healing with no negative effect on final range of motion and are therefore recommended after repair of most full thickness tears. Additionally no definitive evidence supports the use of platelet rich plasma or mesenchymal stem cells regarding improvement of healing rates and clinical outcomes. Further research is needed to identify effective biologically directed augmentations that will improve healing rates and clinical outcomes after rotator cuff repair. | Amir M Abtahi Erin K Granger Robert Z Tashjian | 2015 | World Journal of Orthopedics2015,6,2: | 16 |

| 13 | 枯草芽孢杆菌及饲料粗蛋白质水平对肉鸡生长性能和肉鸡肠道形态的影响显示文摘试验通过检测肉鸡生长性能、胴体品质、肉品质和消化道发育情况、回肠CP消化率,探究日粮中添加枯草芽孢杆菌对肉鸡粗蛋白质(CP)需求量的影响。试验选取720只1日龄肉鸡。设置2×2方阵设计,包括按照标准CP水平设置的对照组(CP 100),在标准基础上降低2%CP含量的试验组(CP 98);不添加枯草芽孢杆菌组及添加枯草芽孢杆菌0.2 g·kg^(-1)组(0.8×10~9cfu·g^(-1),将肉鸡随机分配到各组。每组6个重复,每个重复30只肉鸡。育雏料、生长期饲料和育肥期饲料均按照标准制定,饲料中添加枯草芽孢杆菌对生长性能无显著影响。然而,随着日粮中CP水平下降,体增重和饲料效率显著下降(P<0.05),饲料中添加枯草芽孢杆菌可显著提高肉鸡胴体品质(P<0.05)。添加枯草芽孢杆菌对肉品质无显著影响,然而,随着日粮中CP含量下降,肉的保水力显著下降(P<0.05);空肠隐窝显著变深(P<0.05),回肠CP消化率显著提高(P<0.05)。试验结果表明,日粮中添加枯草芽孢杆菌可改善空肠形态,减缓日粮中CP含量减少的不利影响。因此,益生菌的使用可改变胃肠道形态特征,提高CP的回肠消化率,提高饲料效率。 | Mahmoud K Z Obeidat B S Al-Sadi M Z Hatahet Sh R | 2017 | 饲料博览2017,0,1: | 5 |
| 14 | 年龄相关性黄斑变性的脉络膜厚度评价(英文)显示文摘目的:通过光学相干断层扫描(optical coherence tomography,OCT;RTVue 100-2;V 5.1,Optovue,Fremont,CA,USA)测量比较非新生血管性与新生血管性年龄相关性黄斑变性(age-related macular degeneration,AMD)黄斑中心凹下脉络膜厚度(subfoveal choroidal thickness,SFCT),并分析脉络膜厚度(choroidal thickness,CT)对AMD新血管形成的影响。方法:本研究为回顾性、横断面研究。以单侧眼患有新生血管性AMD且对侧眼患有非新生血管性AMD的24例患者(48眼)作为研究组,选取年龄与眼轴长度相匹配的40例健康眼作为对照组。非新生血管性AMD亚组研究对象是黄斑区有玻璃疣和/或色素变化眼,而新生血管性AMD亚组研究对象是由于脉络膜新生血管而致视网膜下或视网膜内有渗出液和/或脂性渗出眼。运用OCT垂直测量外侧高反射线(视网膜色素上皮层)到脉络膜巩膜交界面间的距离。选取7个不同点进行脉络膜厚度测量,测量区域为距黄斑中心凹颞侧和鼻侧1500μm范围,测量间距为500μm。测量结果在亚组间进行统计学对比研究。结果:研究组患者平均年龄为72.4±8.97(60~82)岁,对照组受试者平均年龄为71.2±8.8(58~81)岁。新生血管性AMD组中平均SFCT明显大于非新生血管性AMD组的厚度(P<0.05)。非新生血管性AMD组中,平均SFCT与平均鼻、颞侧脉络膜厚度比较,差异无统计学意义(P>0.05);而新生血管性AMD组中,平均SFCT与平均鼻、颞侧脉络膜厚度比较,差异有统计学意义(P<0.05)。结论:运用OCT对脉络膜厚度进行测量,有助于理解AMD的病理生理机制。然而,仍需要大型前瞻性研究来探求新生血管性AMD中SFCT增厚的原因。 | Erkan Unsal Kadir Eltutar Ozen Ayranci Osmanbasoglu Sibel Zιrtιloglu Osman Kιzιlay Hulya Gungel | 2014 | 国际眼科杂志2014,14,9: | 4 |
| 15 | GENETIC PROGRAMMING TO PREDICT SKI-JUMP BUCKET SPILLWAY SCOUR显示文摘Researchers in the past had noticed that application of Artificial Neural Networks (ANN) in place of conventional statistics on the basis of data mining techniques predicts more accurate results in hydraulic predictions. Mostly these works pertained to applications of ANN. Recently, another tool of soft computing, namely, Genetic Programming (GP) has caught the attention of researchers in civil engineering computing. This article examines the usefulness of the GP based approach to predict the relative scour depth downstream of a common type of ski-jump bucket spillway. Actual field measurements were used to develop the GP model. The GP based estimations were found to be equally and more accurate than the ANN based ones, especially, when the underlying cause-effect relationship became more uncertain to model. | AZAMATHULLA H.

| 17 | High adiponectin levels fail to protect against the risk of hypertension and,in women,against coronary disease:involvement in autoimmunity?显示文摘AIM:To investigate whether serum adiponectin protects against cardiometabolic risk in a population sample with prevailing metabolic syndrome.METHODS:Middle-aged adults representative of a general population with baseline circulating adiponectin measurements(n=1224)were analyzed prospectively at a mean of 3.8 years’follow-up,using continuous values or sex-specific tertiles.Total adiponectin was assayed by an ELISA kit.Type-2 diabetes was identified by criteria of the American Diabetes Association.Hypertension was defined as a blood pressure≥140 mmHg and/or≥90 mmHg and/or use of antihypertensive medication.Outcomes were predicted using Cox proportional hazards regression analysis in models that were controlled for potential confounders.RESULTS:In models of multiple linear regression,sex hormone-binding globulin,fasting insulin(inverse)and,in men,age were significant independent covariates of serum adiponectin which further tended in women to be positively associated with serum creatinine.Cox regression analyses for incident coronary heart disease(CHD),adjusted for sex,age,non-HDL cholesterol,waist circumference and C-reactive protein,revealed significant inverse association with adiponectin tertiles in men but not women(HR=0.66;95%CI:0.32-1.38 for highest tertile).Cox regression for type-2 diabetes in a similar model(wherein glucose replaced non-HDL cholesterol),adiponectin tertiles appeared to protect in each gender.HR for incident hypertension roughly displayed unity in each of the adiponectin tertiles(P-trend=0.67).CONCLUSION:High adiponectin levels failed to protect against the development of hypertension and,in women,against CHD,presumably paralleling impairment in renal function as well.Involvement of adiponectin in autoimmune complex with loss of antioxidative-antiatherogenic properties may be underlying. | Altan Onat Mesut Aydln Günay Can Bayram Kroglu Ahmet Karagz Servet Altay | 2013 | World Journal of Diabetes2013,4,5: | 3 |
