Background: Bangladesh’s tea industry is essential to the country’s economic expansion. Since tea workers in Bangladesh are marginalized within our community, they have limited access to comprehensive eye care services. Productivity and well-being are cornerstones of comprehensive health care strategy. Ocular disorders are influenced by life expectancy, sociodemographic status, and the epidemiological transition. In this context, the state of ocular health and the many eye illnesses remain to be significantly addressed. Purpose: To evaluate the pattern of eye diseases among tea workers in a tea estate of Bangladesh. Methods: This cross-sectional observational study was carried out in Halda Valley Tea Estate, Nazirhat, Fatickchari, Chattogram, Bangladesh, under the supervision of the Department of Community Ophthalmology, BSMMU, following ethical clearance and approval by the IRB board of BSMMU. With informed written consent and approval from the authority of the tea estate, a total of 110 tea workers were recruited. Socio-demographic characteristics, ocular findings, and patterns of eye diseases were determined and recorded. Results: The mean age of the study participants was 39.60 ± 11.63 years. The maximum (58.1%) study participants were 31 - 50 years old, female (64.5%), illiterate (82.7%), and tribal (71.8%) indigenes. Eye diseases were found in 94.5% of workers. Presbyopia (28.2%), cataracts (27.3%), and refractive error (26.4%) were the most common. Tea workers with eye diseases were significantly older than those who did not have any eye diseases (40.20 ± 11.57 vs. 29.17 ± 7.31 years, p Conclusion: A significant number of tea workers had eye diseases, of which presbyopia, cataracts, and refractive error were the most common.

An attempt has been made in this article to accumulate and elucidate the literatures about the allelopathic potentiality of medicinal plants, and its role on the development of bio-herbicides for eco-friendly weed management strategies to conserve bio-diversity and ecological balance. This review paper has been prepared by comprehensive studies of various published research articles, books and proceedings available in the world literature. The farmers of different countries use several weed management techniques in order to minimize the deleterious effect of weeds. Among them most commonly used practice is application of herbicides due to its high efficacy and cost effectiveness, less time-consuming nature, flexibility and easy accessibility, and more rapid out return. Although use of synthetic herbicides in the crop fields has increased the crop production as well as the productivity by reducing the weed infestation, over time it causes a number of environmental hazards. Hence, to avoid these detrimental effects of synthetic herbicide, a lot of efforts have been dedicated by the researchers to search the novel natural plant products mainly allelochemicals and try to apply them as a tool for the development of bio-degradable natural herbicides. This paper intended to reflect the current state of allelopathic medicinal plants and their potentiality to develop eco-friendly and natural product-based herbicides for sustainable agriculture, and to invite further debate on this issue.

如今,各领域都需要尽可能高的网络可用性和尽可能小的数据丢失概率。因此,在网络设计过程中需要提供冗余,但相应地,也会需要更高的管理和运营成本。冗余协议有助于解决这个问题。第一跳冗余协议群(FHRP)可减少网络通信中从源到目的地的数据丢失。第一跳冗余协议群包括三个协议:热备用路由器协议(HSRP),虚拟路由器冗余协议(VRRP)和网关负载平衡协议(GLBP)。每个协议都有自己的目的,各有利弊。FHRP旨在减少流量损失。这些协议通过建立关联,从而成功地将流量从源传输到目标。在发生故障的情况下,将自动启动备用服务器继续发送流量。HSRP协议和GLBP协议是Cisco专有的,而VRRP协议是电气和电子工程师协会(IEEE)标准。本文通过多种仿真进行了协议之间的比较,以确定哪种协议在哪种情况下最佳。如果由于某些技术问题导致网络中的一个路由器中断,协议仍能够传输流量。此外,我们通过基于md5算法对上述协议进行了验证。通过使用不同的路由协议(如FHRP)包含md-5认证来模拟网络,完成md-5认证的分析。本文仿真基于GNS3平台,重点是实现在不影响网络有效性的情况下进行加密、高效、可靠的信息交换。

Journal of Coastal Life Medicine 2017年第8期5卷 360-364页

作者： Sajan Das Rumana Akhter Sumana Khandaker Sumaiya Huque Promit Das md.Rafi anwar Kaniz Afroz Tanni Samia Shabnaz Mohammad Shahriar Phytochemistry Research Laboratory Department of PharmacyUniversity of Asia PacificDhaka-1215Bangladesh

Objective: To evaluate the possible phytochemical constituents, antibacterial and anthelmintic activity of Coix lacryma-jobi L. (Job's tears) using the chloroform leaves and seed extracts. Methods: The test for antibacterial activity and minimum inhibitory concentration was conducted by the disc diffusion and two-fold dilution method, respectively. In anthelmintic activity test, using Pheretima posthuma model, vermifuge and vermicidal activity were determined by using the chloroform extract at various concentrations. Results: The preliminary phytochemical screening of chloroform extracts of Job's tears leaves indicated the presence of alkaloid, carbohydrate, saponin, glycosides, flavonoids, phenols, tannins and steroids whereas the seeds extract contained glycosides, flavonoids, phenols and steroids, which revealed highest antimicrobial activity against Bacillus cereus and Klebsiella pneumoniae. The lowest minimum inhibitory concentration (12.5–50 mg/mL) was observed against all selected bacteria. On the other hand, it has been observed that chloroform leaves extracts showed shortest time of paralysis (P = 8.17 min) and death (D = 18.23 min) at 100 mg/mL concentration, in comparison with seed extracts (P = 36.83 min and D = 62.33 min) at 100 mg/mL concentration and albendazole (10 mg/mL) used as reference drug (P = 20.17 min and D = 43.67 min), which indicated the plant possessed mild anthelmintic activity. Conclusions: The chloroform extracts (leaves and seeds) showed efficacy for both bacterial infections and parasitic diseases, which ensure the traditional uses of Coix lacryma-jobi L.

The incidence of dengue in Malaysia has shown an increasing trend since the year 2000. Vector control is the primary approach for dengue control in Malaysia. There is an urgent need for new or modified approaches such as the residual spraying on the outer walls that can potentially last long enough to control the Aedes population, particularly in the outbreak-prone areas. In this field study, we conducted outdoor residual spraying (ORS) using a newly formulated polymer-enhanced suspension concentrate (SC-PE) of deltamethrin. The objectives of this study were to evaluate the efficacy of ORS using deltamethrin SC-PE and its effect on wild Aedes populations and to assess its residual bio-efficacy on painted cement walls against the pyrethroid-susceptible strains of laboratory-reared Aedes mosquitoes. Three rounds of spraying in a four-month cycle were conducted between 2014 and 2015 in four residential areas (low-rise and high-rise housing types) in Hulu Langat, Selangor. The bio-efficacy of the insecticide was evaluated by assessing its impact on vector population using ovitrap surveillance. Standard WHO wall deposit bioassay was adapted to determine bio-efficacy of deltamethrin, i.e. post 30 min knockdown and post 24 h mortality after exposure. During the treatment period, we observed significant reductions in the population of Ae. albopictus in the sprayed low-rise housing in both semi-indoor and outdoor environments, while in the high-rise housing, there was also a significant decline in Ae. aegypti population in the semi-indoor environment. The evaluation of the residual bio-efficacy of deltamethrin SC-PE against laboratory-reared Aedes mosquitoes showed that the insecticide lasted longer in the high-rise housing compared to the low-rise housing with >80% mortality achieved continuously for 16 weeks. We provide initial evidence on residual efficacy of deltamethrin SC-PE in reducing Aedes population size in the low-rise and high-rise housing. Our results showed tha
