Tea is one of the most widely consumed beverages in the world. Black tea, obtained from the leaves of Camellia sinensis is the preferred beverage in India and in most western countries. Epidemiological studies on black tea and cancer are limited. However, preliminary studies indicate a positive correlation between black tea consumption and a lower incidence of breast and ovarian cancer. In the present communication, we wanted to see the effect of black tea extract and the polyphenol theaflavin on cell-ECM interaction, MMP activity etc. to strengthen the anti-cancer effect of black tea.

Malaysian Agriculture Research and Development Institute （MARDI） is the country＇s major custodian of the nation＇s crops genetic resources. It has a global responsibility in the conservation of genetic resources of banana, sweet potato and citrus, and national responsibility for the conservation of crops, such as rice, tropical fruits and some herbs and medicinal plant species. MARDI rice seed genebank at Seberang Prai in the state of Penang was established in 1984 and currently holds 12,770 registered rice accessions, of which 53% are of local origin. In addition, MARDI also conserves genes in the field, mostly for underutilized tropical fruit genetic resources. At present, about 168 species of underutilized, rare and wild tropical fruit species consisting of about 2,000 accessions, the largest in the country, are being conserved. The species include ＂kuini＂（Mangifera odorata）, ＂bacang＂（Mangifera foetida）, ＂binjai＂（Mangifera caesia）, ＂cerapu＂（ Garcinia praniana）, ＂rambai＂（Baccaurea motleyana）, ＂asam gelugor＂（ Garcinia atroviridis）, ＂terap＂（drthocarpus odoratissimus） and ＂pulasan＂（Nephellium rambutan-ake）. The accessions are mostly conserved ex situ in field genebanks located at the various MARDI stations throughout the country. Although the conservation of the various crop species genetic resources is important, the real challenge is enhancing its utilisation. The main objective of the paper was to share and disseminate information related to works conducted and strategies opted by MARDI on the conservation and utilization of crop genetic resources. Information on species of crops that are available in MARDI＇s genebank was also highlighted together with brief information of some of the associated traits of significant importance posses by those genetic resources.

BACKGROUND: Acute appendicitis is the most common surgical condition presented in emergency departments worldwide. Clinical scoring systems, such as the Alvarado and modified Alvarado scoring systems, were developed with the goal of reducing the negative appendectomy rate to 5%–10%. The Raja Isteri Pengiran Anak Saleha Appendicitis(RIPASA) scoring system was established in 2008 specif ically for Asian populations. The aim of this study was to compare the modif ied Alvarado with the RIPASA scoring system in Kuwait ***: This study included 180 patients who underwent appendectomies and were documented as having "acute appendicitis" or "abdominal pain" in the operating theatre logbook(unit B) from November 2014 to March 2016. The sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV), diagnostic accuracy, predicted negative appendectomy and receiver operating characteristic(ROC) curve of the modified Alvarado and RIPASA scoring systems were derived using SPSS statistical ***: A total of 136 patients were included in this study according to our criteria. The cut-off threshold point of the modif ied Alvarado score was set at 7.0, which yielded a sensitivity of 82.8% and a specif icity of 56%. The PPV was 89.3% and the NPV was 42.4%. The cut-off threshold point of the RIPASA score was set at 7.5, which yielded a 94.5% sensitivity and an 88% specif icity. The PPV was 97.2% and the NPV was 78.5%. The predicted negative appendectomy rates were 10.7% and 2.2% for the modif ied Alvarado and RIPASA scoring systems, respectively. The negative appendectomy rate decreased significantly, from 18.4% to 10.7% for the modified Alvarado, and to 2.2% for the RIPASA scoring system, which was a signif icant difference(P<0.001) for both scoring ***: Based on the results of this study, the RIPASA score is a simple scoring system with better sensitivity and specif icity than the modif ied Alvarado scoring system in A

钛合金材料因其优异的耐腐蚀性能和机械性能被认为是反应堆的候选结构材料。本文围绕材料服役过程中的辐照损伤机制问题,采用分子动力学(md)方法研究了金属钛(以α-Ti为例)的辐照级联过程,获得了不同温度(300、500、700和900 K)、不同能量(1、5、10和20 keV)的初级碰撞原子(PKA)沿不同晶格方向([0001]、[1010]和[1100])入射的碰撞过程,并从原子尺度分析了α-Ti在辐照级联过程下的缺陷演化行为及机制。结果表明,随着温度升高,α-Ti级联碰撞过程诱发的峰值点缺陷数明显增加,缺陷复合过程所需时间延长;随着PKA能量增加,整个缺陷演化过程的缺陷数均明显增加,稳定缺陷数也呈增加趋势;而PKA入射方向对级联过程中缺陷演化无明显影响。采用NRT(Norgett-Robinson-Torrens)模型计算获得α-Ti辐照缺陷随PKA能量的变化趋势与md计算结果一致,级联碰撞后剩余的缺陷数约占NRT预测值的30%。本文从微观角度研究了金属钛的辐照损伤机理,相关计算结果为钛合金在未来核反应堆中的应用提供数据支持,为新型耐辐照材料研发提供理论依据。

本文研究了含碳为0.15％的钢添加V、N及Al形成第二相粒子对奥氏体晶粒粗化行为的影响。氧化和浸蚀技术被用以显示原奥氏体晶界。试样在900℃到1150℃范围内,高真空(<10^(-4)托)下奥氏体化半小时,每次奥氏体化的温度间隔为50℃,在接近结束前一分钟左右时,输入约250mmHg压力的氧气使试样氧化,以显示奥氏体晶界,然后在冰水中淬火。在这些钢中,原始奥氏体晶粒尺寸随温度的变化表明,在整个温度范围内,V(C,N)对奥氏体晶粒细化的影响比VC大得多,而与AlN或多或少有些相似之处。

The aim of the current study is to investigate the effect of combination of glibenclamide;an antidiabetic drug and simvastatin;a HMG-CoA reductase inhibitor on long-term (four weeks) alloxan-induced diabetes rats (ADRs). Methods: Alloxan (120 mg/kg body weight, BW) was injected intra-peritonially (i.p.) in rats. At first alloxan (120 mg/kg BW) induced diabetic rats were treated with single dose of glibenclamide (1.2 mg/70kg BW) and simvastatin (10 mg/70kg BW) for two weeks. Then fixed dose combinations of glibenclamide (0.6 mg/70kg BW) and simvastatin (5 mg/70kg BW) were injected along with those of two drugs for four weeks. Results: At first it was found that glibenclamide reduced significant amount of glucose in blood, but it had no significant effect on lipid profile on short term (two weeks) ADRs. In contrast, simvastatin had no effect on blood glucose level, whereas it significantly reduced total cholesterol (TC), triglycerides (TG) and low density lipoprotein cholesterol (LDL-C) and increased significant amount of high density lipoprotein cholesterol (HDL-C). However, pathological changes of pancreas’s Islets of Langerhans were observed only after long-term (four weeks) induction of alloxan in rats. The inhibitory effect of combination therapy on blood glucose, TC, TG and LDL-C level was higher than those of monotherapy alone on long term ADRs. In addition, treatment with combination therapy on long term ADRs showed higher amount of HDL-C level and super oxide dismutase and catalase enzyme activity than those with monotherapy. They also decreased serum glutamic pyruvic transaminase (SGPT) and Serum glutamic oxaloacetic transaminase (SGOT) level. Administration of simvastatin recovered Langerhans cells from shrinkage whereas glibenclamide displayed slight recovery. But the combination therapy showed complete recovery of Langerhans cells as compared with diabetic rats. Conclusion: Our present findings suggest that treatment of glibenclamide in combination with s
