在将来,减小胶料偏差将成为橡胶厂改进产品质量、满足用户需要、避免损失时间及不合格材料的关键因素,橡胶厂减小胶料偏差的能力取决于材料偏差和测试试验。借助于下面推荐的测试仪器,硫化仪测试数据的偏差能明显减小。改进测量硫化的数据有助于减小数据偏差,但进一步的改善则要求重新设计仪器。ODR 2000和NDR 2000型硫化仪由于改进设计能提高仪器的性能水平。2000型系列硫化仪对操作者影响不敏感。附加了很多新的功能以便提高试验效率并维持硫化仪最佳性能。随着更多重复测试数据的出现,硫化仪测试能在更高要求的未来世界继续服务于橡胶加工过程。

前言蜡是精炼的石油产品.可粗分为石蜡和微晶蜡两大类。与微晶蜡比较,石蜡的分子量较小、熔点较低、线型或直链烃含量较高,结晶度较大。通常认为混入橡胶中的蜡能移栖至橡胶表面,从而形成一道不可渗透的屏障,起到防护臭氧的浸蚀的作用。蜡向表面“移栖”或者”喷出”的能力取决于蜡的类型、胶料的组成、在臭氧中暴露前和暴露时的时间和温度。所有这些参数都会影响到每一种蜡在胶料中的溶解度和迁移性。本文讨论会影响各种石油类蜡喷出速率的诸因素。具体论题包括:各种蜡的移栖特牲、蜡的浓度以及时间和温度的影响,这些与移栖

作者： Naini A.B. Lu J. Kaufmann P. S. dimauro 黄卫东 4-420 Coll. of Phys. and Surgeons 630 W 168th St New York NY 10032 United States Dr.

Background: The mitochondrial DNA gene encoding subunit 5 of complex I (ND5) has turned out to be a hot spot for mutations associated with mitochondrial encephalomyopathy with lactic acidosis and strokelike episodes (MELAS) and various overlap syndromes. Objective: To describe a novel mutation in the ND5 gene in a young man man with an overlap syndrome of MELAS and myoclonus epilepsy with ragged-red fibers. Design: Case report. Patient: A 25-year-old man had recurrent strokes, seizures, and myoclonus. His mother also had multiple strokes. A muscle biopsy specimen showed no ragged-red fibers but several strongly succinate dehydrogenasereactive blood vessels. Results: Biochemical analysis showed isolated complex I deficiency and molecular analysis revealed a novel heteroplasmic mutatio n (G13042A) in the ND5 gene. Conclusions: These data confirm that ND5 is a genet ic hot spot for overlap syndromes, including MELAS and strokelike and myoclonus epilepsy with ragged-red fibers.

Background: Mutations in polymerase γcause progressive external ophthalmopleg ia and a variety of associated symptoms and signs, including neuropathy, ataxia, hypogonadism, hearing loss, muscle weakness, and psychiatric problems. Extrapyr amidal signs have been rarely described. Objective: To describe a family with a novel polymerase γ.mutation and autosomal dominant transmission of progressive external ophthalmoplegia, neuropathy, hypogonadism, and parkinsonism. Design: Ca se report. Patients: The proband, a 49 year old woman with incipient parkinson ism, and her 59 year old brother with overt parkinsonian features. Main Outcom e Measures: Mutation in the proband by sequencing the polymerase γgene and in a ffected relatives by restriction fragment length polymorphism analysis. Results: We found multiple mitochondrial DNA deletions in the proband’s muscle and a no vel missense mutation in the polymerase γgene (A2492G) in the proband and in he r affected siblings. Conclusion: Parkinsonism was a prominent clinical feature i n this family with autosomal dominant ophthalmoplegia, multiple mitochondrial DN A deletions, and a novel mutation in the polymerase γgene.

The study explored the relationship between the performance of calves and calving season in a Mediterranean rangeland-based beef livestock *** multiparous Sarda cows,grazing on a natural pasture,with two distinct calving periods(group A,11 animals,calving date 15/10/2016±16(means±s.d.),and group W,nine animals,calving date 26/01/2017±11)were *** data,herbage quality,daily milk yield(DMY),total milk yield(TMY),body weight(BW)of cows and calf,body-weight daily gain(ADG)of calves,body condition score(BCS)and calving interval(CI)of cows were assessed.A mixed-effects model was used to DMY and ADG data while TMY,BCS,weaning weight(WW)and CI data were analyzed by a linear *** most determining factors in the DMY and ADG were detected by means of partial least square regression(PLSR)*** W showed higher DMY(6.5±0.3 kg/d vs.4.5±0.3 kg/d,p<0.001)and TMY(1,189±70 kg vs.830±60 kg,p=0.002)than Group A,but this did not result in a greater ADG of calves(Group A:0.83±0.04 kg/d/animal and Group W:0.99±0.09 kg/d/animal,p-value not significant)or WW when adjusted for their age(Group A:216±14 kg/animal and Group W:250±22 kg/animal,p-value not significant).In contrast,the WW actually measured were higher in Group A than in Group W(257±7 kg vs.175±8 kg,p<0.001).The Group W cows experienced a minor CI than Group A cows(288±13 d vs.320±8 d,p=0.04).The results of PLSR suggest that the factors with utmost importance for both DMY and ADG were the age and the body-weight of cows,highlighting the excellent maternal ability of Sarda breed and its good adaptation to environment.

他汀类药物相关性肌病的肌肉辅酶Q10水平

世界核心医学期刊文摘(神经病学分册) 2006年第4期 13-13页

作者： Lamperti C. Naini A.B. Lucchini V. S. dimauro 赵天智 4- 420 College of Physicians and Surgeons 630 W 168th St New York NY 10032 United States.Dr

Background: Statin drugs (3- hydroxy- 3- methylglutaryl coenzyme A reductase inhibitors) reduce the level of cholesterol by inhibiting the synthesis of mevalonate, an intermediary in the cholesterol biosynthetic pathway. Use of statin drugs has been associated with a variety of skeletal muscle-related complaints. Coenzyme Q10 (CoQ10), a component of the mitochondrial respiratory chain, is also synthesized from mevalonate, and decreased muscle CoQ10 concentration may have a role in the pathogenesis of statin drug-related myopathy. Objectives: To measure the CoQ10 concentration and respiratory chain enzyme activities in muscle biopsy specimens from 18 patients with statin drug-related myopathy and to look for evidence of apoptosis using the TUNEL (terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling) assay. Design: An open-labeled study of CoQ10 concentration in muscle from patients with increased serum creatine kinase concentrations while receiving standard statin drug therapy. Setting: Neuromuscular centers at 2 academic tertiary care hospitals. Results: Muscle structure was essentially normal in 14 patients and showed evidence of mitochondrial dysfunction and nonspecific myopathic changes in 2 patients each. Muscle CoQ10 concentration was not statistically different between patients and control subjects, but it was more than 2 SDs below the normal mean in 3 patients and more than 1 SD below normal in 7 patients. There was no TUNEL positivity in any patients. Conclusion: These data suggest that statin drug-related myopathy is associated with a mild decrease in muscle CoQ10 concentration, which does not cause histochemical or biochemical evidence of mitochondrial myopathy or morphologic evidence of apoptosis in most patients.
