Rubber leaf powder （an agricultural waste） was treated with potassium permanganate followed by sodium carbonate and its performance in the removal of Pb（II） ions from aqueous solution was evaluated. The interactions between Pb（II） ions and functional groups on the adsorbent surface were confirmed by Fourier transform infrared （FT-IR） spectroscopy, scanning electron microscopy （SEM） coupled with X-ray energy dispersive spectroscopy （EDX）. The effects of several important parameters which can affect adsorption capacity such as pH, adsorbent dosage, initial lead concentration and contact time were studied. The optimum pH range for lead adsorption was 4-5. Even at very low adsorbent dosage of 0.02 g, almost 100% of Pb（II） ions （23 mg/L） could be removed. The adsorption capacity was also dependent on lead concentration and contact time, and relatively a short period of time （60-90 min） was required to reach equilibrium. The equilibrium data were analyzed with Langmuir, Freundlich and Dubinin-Radushkevich isotherms. Based on Langmuir model, the maximum adsorption capacity of lead was 95.3 mg/g. Three kinetic models including pseudo first-order, pseudo second-order and Boyd were used to analyze the lead adsorption process, and the results showed that the pseudo second-order fitted well with correlation coefficients greater than 0.99.

Refractive errors and biometry of primary angle-closure disease in a mixed Malaysian population

引用

International Journal of Ophthalmology(English edition) 2017年第8期10卷 1246-1250页

作者： Jelinar mohamed-noor Dhaniah Abd-Salam Department of Ophthalmology Hospital Kuala Lumpur JalanPahang Kuala Lumpur 50586 Malaysia

AIM： To assess the refractive status, anterior chamber depth （ACD） and axial length （AL） of patients with primary angle-closure disease （PACD）. METHODS： Retrospective cohort. Data was collected from charts of all PACD patients treated from April 2013 to December 2015. Analysis was done on 137 patient charts with complete biometric data. Patient demographics, PACD type, refractive status （spherical equivalent）, ACD and AL were studied. RESULTS： The median age of 137 subjects [53 with primary angle-closure suspects （PACS）, 27 with primary angle- closure （PAC） and 57 with primary angle-closure glaucoma （PACG）] was 68y （range 21-88y）. The majority was Chinese （n=68; 49.6%） and most of them were women （n=75; 54.7%）. The distribution of myopia （n=51; 37.2%） and hyperopia （n=49; 35.8%） was similar. The ACD was shallower in myopes compared to hyperopes （P=-0.02） and emmetropia （P=-0.049） but the AL was not significantly different between groups. There were no patients blind from PACG. CONCLUSION： Both myopia and hyperopia can occur in PACD. Despite a shallower ACD in angle closure myopes, the AL was not different between groups.

The protective effects of procyanidin C-1 on bisphenol A-induced testicular dysfunction in aged mice

The number and quality of sperm are decreased due to bisphenol A(BPA) exposure, an endocrine-disrupting chemical on the male reproductive system, especially in advanced paternal age(APA). Procyanidin C-1(PCY-1), an antioxidant from grape seed(Vitis vinifera L.), has demonstrated anti-viral, anti-melanogenic and immunostimulatory effects. Therefore, this study aims to determine the effects of PCY-1 intervention on sperm parameters, testis morphological changes, serum testosterone, oestradiol, and luteinizing hormone(LH) concentrations and the expression of apoptotic(Bax and Bcl-2) and mitochondria-related(Mfn1 and Opa1) genes in BPA-exposed aged mice. Results revealed that PCY-1 intervention improves aged male fertility in BPA-exposed conditions by decreasing abnormal sperms percentage and increasing spermatogenic cell diameter and epithelial height. PCY-1 also decreased oestradiol, and increased LH and testosterone levels. The gene expression of Bax was significantly down-regulated by PCY-1 intervention. In contrast, Bcl-2 was substantially up-regulated. Expression of Mfn1 and Opa1 genes were also significantly up-regulated in the PCY intervention group. Hence, it is demonstrated that PCY-1 was able to mitigate the adverse effects of BPA on reproductive parameters of aged mice. Collectively, we postulated that PCY-1 has a potential role in protecting the ageing male reproductive system against the damaging impacts of BPA.

An engine rubber mounting is one of the important parts of a vehicle. It is a function to isolate or absorb and to reduce vibration to the vehicle body thus to the passenger itself. Due to the engine compartments environment such as heat and massive vibration due to road conditions, the engine rubber mountings lifespan has been reduced. Thus several studies have been conducted to upgrade the material lifespan to make it more reliable and better engine mounting components. This paper presents the conceptual design of kenaf fiber polymer as automotive engine rubber mounting composites using the integration of Theory of Inventive Problem Solving(TRIZ). In this early stage, the solution is generated using 40 inventive principles and TRIZ contradiction method. The solution parameter for the specific design character is the selected using the morphological chart to develop a systematic conceptual design for the component. Four(4) innovative design concepts were produced and Analytic Network Process(ANP)methods were utilized to perform the multi-criteria decision-making process of selecting the best concept design for the polymer composite engine rubber mounting component.
