AIM:To determine the association between distance and near visual acuity(VA)and cognitive function among older adults in Selangor,***:A total of 230 older adults(age≥60y)participated in this *** distance and near VA were measured using the Early Treatment Diabetic Retinopathy Study Chart and Lighthouse Near Visual Acuity Chart,*** cognitive function was assessed using the Mini-Mental State Examination(M-MSE)and the Malay language version of the Montreal Cognitive Assessment(M-MoCA).Digit Symbol(DS)subtest was used to measure information ***:No significant association was observed between vision and M-MSE and M-MoCA ***,poor distance and near VA were found to be significantly associated with low DS scores[distance VA:β=-0.01,R2=0.1,P=0.02;odds ratio(OR)=2.84,95%confidence interval(CI),1.10-7.33,P=0.03;near VA:β=-0.05,R2=0.08,P=0.00;OR=3.32,95%CI,1.28-8.59,P=0.01].CONCLUSION:Poor vision is associated with a decline in information processing in older adults and substantiates the importance of preserving good vision in maintaining cognitive function.

Proapoptotic activities of Oroxylum indicum leave extract in HeLa cells

引用

Asian Pacific Journal of Tropical Biomedicine 2019年第8期9卷 339-345页

作者： Nurul Hidayah Wahab Nur Afina Mohd din Yee Ying Lim Noor Izani Noor Jamil Nor Fazila che Mat School of Health Sciences Health Campus Universiti Sains Malaysia

Objective: To examine the proapoptotic properties of Oroxylum indicum methanol extract on cervical cancer cells. Methods: Methylene blue assay was used to determine the IC50 value of the extract. Western blotting assays were done to analyze the expression of HPV oncoproteins (HPV18 E6 and E7) and apoptotic molecules (caspase-3 and caspase-8). Reverse transcriptase PCR assays were performed to determine genetic alteration of tumor suppressors p53 and pRb and apoptosis markers Fas and FasL. Enzyme-linked immunosorbent assay (ELISA) was done to determine the expression of cytokine levels (IL-6 and IL-12). Results: The determination of IC50 value indicated a higher anti-proliferative activity of the extract compared to cisplatin. After 24 hours of treatment, Western blot analysis showed that treated HeLa cells exhibited a significant down-regulation of HPV18 oncoproteins E6 and E7, and a significant induction of caspase-8 and caspase-3 activation level. Meanwhile, the mRNA expressions of p53, pRb, Fas and FasL were significantly upregulated in treated cells. Moreover, ELISA showed an increased IL-12 and decreased IL-6 production after Oroxylum indicum treatment. Conclusions: The methanol extract of Oroxylum indicum has an anti-proliferative activity and proapoptotic potential. It induces localized-immunity improvements by altering cytokine production in HPV-positive cervical cancer cells.

Regular Stereo Matching Improvement System Based on Kinect-supporting Mechanism

引用

Open Journal of Applied Sciences 2013年第1期3卷 22-26页

作者： din-Yuen Chan che-Han Hsu Department of Computer Science and Information Engineering National Chiayi University Chiayi City Chinese Taipei

In this paper, we built a stereoscopic video associated experimental model, which is referenced as Kinect-supporting improved stereo matching scheme. As the depth maps offered by the Kinect IR-projector are resolution-inadequate, noisy, distance-limited, unstable, and material-sensitive, the appropriated de-noising, stabilization and filtering are first performed for retrieving useful IR-projector depths. The disparities are linearly computed from the refined IR-projector depths to provide specifically referable disparity resources. By exploiting these resources with sufficiency, the proposed mechanism can lead to great enhancement on both speed and accuracy of stereo matching processing to offer better extra virtual view generation and the possibility of price-popularized IR-projector embedded stereoscopic camera.

金刚石/铜复合材料具有低膨胀系数和高热导率等优异性能,使其成为一种理想的电子封装材料。采用97%(72Ag-28Cu)-3%Ti活性钎料对金刚石/铜复合材料和氧化铝陶瓷进行钎焊。发现活性钎料在氧化铝陶瓷和金刚石薄膜表面均具有良好的润湿性,在两者表面的平衡润湿角均小于5°。讨论了主要钎焊条件(如钎焊温度和保温时间等)对接头性能的影响。发现钎焊过程中Ti元素聚集在金刚石颗粒的表面形成TiC化合物,且TiC化合物的形貌与钎焊接头的剪切强度具有紧密联系。推测合适的TiC化合物层厚度可改善钎焊接头的剪切强度,而颗粒状的TiC化合物及过厚的TiC化合物层却会损害钎焊接头的性能。获得的最大剪切强度为117MPa。

Etiologies of tropical acute febrile illness in West Pahang, Malaysia: A prospective observational study

引用

Asian Pacific Journal of Tropical Medicine 2020年第3期13卷 115-122页

作者： Alif Adlan Mohd Thabit Mohd Hatta Abdul Mutalip Wan Mohd Rasis Wan Ahmad Kamil Mohd RamadhanMohd din Mohan Arumugam Siti Sanaa Wan Azman Roslinda Jaafar Sathvinder Singh Gian Singh RafidahAbdullah Eida Nurhadzira Muhammad Nor Asiah Muhamad Department of Medicine Hospital Bentong BentongPahangMalaysia Institute for Public Health National Institute of HealthMalaysiaMinistry of Health MalaysiaSelangorMalaysia Department of Medicine Hospital Sultan Haji Ahmad Shah TemerlohPahangMalaysia Department of Pathology Hospital Sultan Haji Ahmad Shah TemerlohPahangMalaysia Department of Medicine Hospital Kuala Lipis Kuala LipisPahangMalaysia

Objective: To determine the etiologies of tropical acute febrile illness(TAFI) in West Pahang, Malaysia and to investigate morbidity and mortality factors in relation to TAFI. Methods: A multicenter prospective cohort study was conducted between January and June 2016 in six district hospitals throughout the western part of Pahang State in Peninsular Malaysia. A total of 336 patients answered a standardized questionnaire and blood samples were collected for laboratory confirmation of infectious etiology. Descriptive analysis and logistic regression were performed to identify factors associated with TAFI. Results: A total of 336 patients were included. The patients were mainly Malays(70.2%), males(61.3%), aged(44.6±17.4) years, with more than half(58.9%) presenting with gastrointestinal symptoms. The majority were diagnosed with dengue(35.7%) while malaria(4.5%) was the least frequent. The in-hospital mortality due to TAFI was 9.2%. Patients with meliodosis had five times higher mortality [Adjusted OR: 5.002, 95% CI:(1.233, 20.286)]. Patients with comorbidities such as cardiovascular symptoms(P<0.001) and renal replacement therapy initiation(P<0.001) were significantly associated with in-hospital mortality in all TAFI. Conclusions: The etiology of TAFI in the western Pahang includes dengue, leptospirosis, malaria and melioidosis, which carry the highest risk of in-hospital mortality. The presence of cardiovascular symptoms may be used to assess the disease severity in TAFI, but more studies are needed in the future.

根据对三亚河口海域叶绿素a(Chl-a)浓度及海洋环境因子的监测结果,分析了Chl-a和各环境因子的空间分布情况,以及Chl-a与各环境因子的相关关系。结果表明,三亚河口海域的表层水温、pH、盐度、悬浮物、高锰酸盐指数、DO、营养盐等环境因子的空间分布明显受到陆地径流注入的影响;该海域的Chl-a浓度较低,表层平均值为0.203mg/m3,底层平均值为0.179mg/m3,且靠近河口采样点的表层Chl-a浓度是底层的数倍,远离河口采样点的底层Chl-a浓度是表层的数倍,造成这种空间分布格局的主要原因可能是靠近河口采样点表层海水中的营养盐更容易得到陆地径流的补充;该海域的Chl-a浓度与无机氮(din)呈极显著负相关,与活性磷(DIP)呈极显著正相关,与两者质量浓度之比(din/DIP)呈极显著负相关,与其他环境因子均不存在相关性,Chl-a浓度主要受磷含量的控制;该海域Chl-a浓度与Cd、Pb、Cu、Hg、As浓度基本未呈现出相关关系。
