This study used epidemiological data of Chinese ferret-badger (CFB) rabies in eastern Taiwan, the Hualien County, from July 2013 to December 2020 to estimate its wave front spread rate. The first case of the CFB rabies virus in eastern Taiwan was detected in Zhuoxi Township in Hualien County on July 31, 2013. Our technique regressed TIME (months elapsed from the first case in Zhuoxi and the first case in each infected township invaded by the first case of CFB rabies) on DISTANCE (kilometers between locations of the first case in Zhuoxi and centroids of each infected township invaded by the first case of CFB rabies), using simple linear regression. The mean rate of wave front spread was 10.698 kilometers/year. The correlation between TIME and DISTANCE was R = 0.9273 at p = 0.0001. As CFB rabies has only occurred in China and Taiwan, studies on its epidemiology are extremely rare. This paper is the first study to estimate the wave front spread rate of CFB rabies in the world.
本研究利用2013年7月至2020年12月台湾东部花莲县中华雪貂獾(CFB)狂犬病流行病学资料,估算其波前传播率。2013年7月31日在花莲县卓溪乡发现台湾东部首例CFB狂犬病毒病例。我们的技术采用简单线性回归方法,将时间(从卓溪市首位病例和首位CFB狂犬病感染乡镇的首位病例之间的时间)与距离(卓溪市首位病例所在位置与首位CFB狂犬病感染乡镇的质心之间的距离)进行回归。平均波前传播速率为10.698 km /年。时间与距离的相关系数R = 0.9273, p = 0.0001。由于CFB狂犬病仅发生在中国大陆和台湾,对其流行病学的研究极为罕见。本文是国际上首次对CFB狂犬病波前传播率进行估算的研究。

The study Evaluated the Impact of Effective Management Practices in Mitigating the Toxicity Symptoms of Pesticides Preparation, Storage and Application in Kebbi State, Nigeria. Structured Questionnaires were used to obtained information from the respondents. Descriptive statistics comprising frequency distribution tables and percentages and were used for Data Analysis. Likert scale was used to determine farmer’s perception on the toxicity symptoms of pesticides of pesticides preparation, storage and application employed by farmers when handling pesticides. The result of the study showed that majority of the respondents (90%) were male while female formed the minority in pesticide usage with only (10%). The study also showed that all the respondents (100%) were married and engaged in agricultural activities. The study further revealed that all the respondents never had any formal training on the use of pesticide from either governmental or non -governmental organizations. The research study also found out that all (100%) of the respondents were not aware of the toxicity of pesticides during preparation, storage and application. Likert Scale Analysis showed a negative perception by farmers on awareness of pesticide toxicity during preparation, storage and application. On perception of the respondents on the toxicity of pesticides during preparation, storage and application, the study revealed that Nausea, Dizziness, Diarrhea, Respiratory Difficulty, Skin Irritation, Rashes, Fever, Peeling of the Skin, Vomiting, and Headache were the serious toxicity effects of pesticide. It is concluded that respondents had negative perception on pesticide management of toxicity of pesticides during preparation, storage and application. It is therefore recommended that appropriate authorities should enforce the use of protective clothing, appropriate equipment and correct handling practices when using pesticides. Existing pesticide regulations and monitoring policies should be enforced. Government should also intensify efforts at registering and controlling distribution of pesticides and banning hazardous ones. It should also enforce the making of less toxic pesticides available to farmers.
该研究评估了尼日利亚Kebbi州有效管理做法对减轻农药制备、储存和施用毒性症状的影响。使用结构化问卷从受访者那里获取信息。描述性统计包括频率分布表和百分比,用于数据分析。采用李克特量表测定农民在处理农药时对农药制备、储存和施用的农药毒性症状的认知。研究结果表明,大多数受访者(90%)为男性,而女性在农药使用方面占少数(10%)。该研究还表明,所有受访者(100%)都已婚并从事农业活动。研究进一步表明,所有受访者从未接受过政府或非政府组织关于农药使用的正式培训。调查还发现,所有(100%)受访者在农药制备、储存和使用过程中都不知道农药的毒性。李克特量表分析显示,农民在农药制备、储存和施用过程中对农药毒性的认识持否定态度。调查对象在农药制备、贮存和施用过程中对农药毒性的认知,研究显示,农药的严重毒性效应为恶心、头晕、腹泻、呼吸困难、皮肤刺激、皮疹、发热、脱皮、呕吐和头痛。调查结果表明,受访者对农药制备、储存和施用过程中农药毒性的管理持否定态度。因此,建议有关当局在使用农药时强制使用防护服、适当的设备和正确的处理方法。应执行现有的农药法规和监测政策。政府还应加大力度登记和控制农药的销售,禁止有害农药。它还应该强制要求为农民生产毒性较低的农药。

The COVID 19 pandemic is one of the worst pandemics that struck the world, after the Spanish flu in 1918 and stalled the entire public health care system. Initially in the absence of definite drugs, the primary mitigation priority was prevention. Its web like spread put pressure on the accessory health care systems too and the most affected were perhaps the Pharmacy. In India the pharmacy are an integral part of health services, with desperate demand for an array of supplies and drugs, affecting the Pharmacies and their functioning tremendously, they too have contributed immensely in the mitigation strategies of the government. The study assesses the pharmacies in terms of their preparedness to cope with the demands and enhancement of role of the pharmacists to provide cost effective and consumer friendly services.Online services were good and satisfactory and were offered by only the big scale pharmacy (67%) ;Pharmacists from small scale set ups were yet to be vaccinated (33.3%), preparedness was optimum in terms masks and sanitization of premises, but IEC materials were missing in the small shops(44.4%); supplies were good and surplus but small scale ones sometimes sold the cost effective one’s; adjuvant drugs were in excess but drugs for moderate to severe form of COVID were limited to facility based pharmacyonly. Non COVID medications,in order to prioritize COVID drugs,went missing.Stock charts were displayed by big and middle level shops. Study suggests the pharmacy role in managing a pandemic is upnteem and periodic checks and regulations should be revised as per needs of the time.
新冠肺炎疫情是继1918年西班牙流感之后袭击世界的最严重的流行病之一,导致整个公共医疗体系陷入停滞。最初在没有明确药物的情况下,缓解的首要重点是预防。它的网络式传播也给附属医疗保健系统带来了压力,受影响最大的可能是药房。在印度,药房是保健服务的一个组成部分,对各种用品和药品的迫切需求极大地影响了药房及其运作,它们也为政府的缓解战略作出了巨大贡献。研究评估各药房是否作好准备,以应付市民的需求,以及如何加强药剂师的角色,以提供具成本效益及方便市民使用的服务。在线服务良好且令人满意,只有大型药房提供(67%);小型药房的药剂师尚未接种疫苗(33.3%),在口罩和场所卫生方面的准备工作是最佳的,但小型商店缺乏信息、教育和宣传材料(44.4%);供应充足且过剩,但小规模的供应商有时会出售具有成本效益的产品;辅助药物过量,但用于中重度COVID的药物仅限于基于设施的药物。非COVID药物,为了优先考虑COVID药物,不见了。大型和中型商店陈列着股票图表。研究表明,药房在管理大流行方面的作用正在上升,定期检查和规定应根据时间的需要进行修订。

Congenital Cytomegalovirus (CMV) infection is one of major public health concerns and one of the most frequent congenital infections worldwide. Congenital CMV infection is under-diagnosed in the majority of asymptomatic pregnant women due to its self-limited non-specific symptoms and unimplemented screening program. Primary CMV infections are associated with the highest in-utero transmission at estimated rates of 30–35%. Transmission rate occurs less frequently in secondary CMV maternal infections at approximately 1.1–1.7%. Congenital CMV infection can also go undetected at birth because the affected newborns are often asymptomatic, however, they manifest serious morbidities later in life. There are growing evidences that early diagnosis and treatment of newborns with congenital CMV infection can reduce sensorineural hearing loss (SNHL) and the subsequent long-term neurological and developmental disabilities. There is also increased interest in establishing a prophylactic CMV vaccine that can protect seronegative mothers from primary infection and augment the immune response in seropositive women, in order to prevent CMV reactivation or re-infection. Studies show that liquid-saliva polymerase chain reaction (PCR) assay has high sensitivity “100%" it is more advantageous than Dried blood spots (DBS) in detecting congenital CMV infection and it can be used to screen newborns in the first 3 weeks. Suggestive strategies to reduce the burden of congenital CMV disease are; establishing a screening programme for pregnant mothers, developing prophylactic CMV vaccine, early therapeutic intervention in pregnant women and newborns and use Saliva PCR assay as a new method for neonatal CMV screening.
先天性巨细胞病毒(CMV)感染是主要的公共卫生问题之一,也是世界上最常见的先天性感染之一。先天性巨细胞病毒感染在大多数无症状孕妇中诊断不足,由于其自限性非特异性症状和未实施的筛查计划。原发性巨细胞病毒感染与最高的宫内传播有关,估计率为30-35%。继发性巨细胞病毒母体感染的传播率较低,约为1.1-1.7%。先天性巨细胞病毒感染也可能在出生时未被发现,因为受影响的新生儿通常无症状,然而,他们在以后的生活中表现出严重的发病率。越来越多的证据表明,新生儿先天性巨细胞病毒感染的早期诊断和治疗可以减少感音神经性听力损失(SNHL)和随之而来的长期神经和发育障碍。人们对建立一种预防性巨细胞病毒疫苗也越来越感兴趣,这种疫苗可以保护血清阴性的母亲免受原发感染,并增强血清阳性妇女的免疫反应,以防止巨细胞病毒再激活或再感染。研究表明,液体-唾液聚合酶链反应(PCR)检测先天性巨细胞病毒感染的灵敏度高达100%,比干血点(DBS)检测更有优势,可用于3周内新生儿的筛查。减轻先天性巨细胞病毒疾病负担的建议策略有:建立孕妇筛查方案,开发巨细胞病毒预防性疫苗,对孕妇和新生儿进行早期治疗干预,并将唾液PCR检测作为新生儿巨细胞病毒筛查的新方法。

In this study modified feldspar composite (MFC) was prepared from the combination of Theobroma cacao pod (TCP) and feldspar (FS) using calcination method. The Theobroma cacao pod-feldspar sample was first Na-modified by treatment using 0.1M NaOH solution before calcination in the muffle furnace at 3000C to complete the process of composite preparation. The Theobroma cacao pods (TCP), feldspar (FS) and modified feldspar composite (MFC) were characterized using XRF, X-ray diffraction (XRD), Brunauer Emmett and Teller ( BET) analysis, scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FTIR). The results showed that the cation exchange capacity of the modified feldspar composite (30.66 ± 0.21 meq/100 g) was 5 times higher than that of raw feldspar (6.42 ± 0.45 meq/100g). More so, the novel biohybrid material, MFC has a surface area of 53.60 ± 0.3 m2/g and particle size of 105.4 ± 0.18. The XRD patterns revealed that after the modification process, there is only slight shift in the position of some diffraction peaks of feldspar and the composite material indicating the retention of the crystalline properties of the feldspar in the novel composite (MFC). FTIR results showed that some functional groups present in the two starting materials were also available on the surface of the composite (MFC) indicating that the intercalation of TCP biomass into feldspar surface was successful. Owing to its improved cation exchange capacity and eco-friendliness, the modified feldspar composite (MFC) has a good potential application as adsorbent for heavy metals in wastewater treatment besides other industrial explorations.
以可可豆荚(TCP)和长石(FS)为原料,采用煅烧法制备了改性长石复合材料(MFC)。可可豆荚长石样品首先用0.1M NaOH溶液进行na修饰,然后在3000C的马弗炉中煅烧,完成复合制备过程。采用XRF、x射线衍射(XRD)、BET、扫描电镜(SEM)和傅里叶变换红外光谱(FTIR)对可可豆荚(TCP)、长石(FS)和改性长石复合材料(MFC)进行了表征。结果表明,改性长石复合材料的阳离子交换容量(30.66±0.21 meq/100g)是原长石(6.42±0.45 meq/100g)的5倍。新型生物杂化材料MFC的比表面积为53.60±0.3 m2/g,粒径为105.4±0.18。XRD谱图显示,改性后长石与复合材料的部分衍射峰的位置发生了轻微的变化,表明长石的晶体性质在新型复合材料(MFC)中得到了保留。FTIR结果表明,两种原料中存在的一些官能团也存在于复合材料(MFC)表面,表明TCP生物质在长石表面的插层是成功的。改性长石复合材料(MFC)具有良好的阳离子交换能力和生态友好性,在废水处理中作为重金属吸附剂具有良好的应用前景。

Irrigated agriculture is dependent on an adequate water supply of usable quality. Water containing impurities, which are injurious to plant growth, are not satisfactory for irrigation. Water quality for agricultural purposes is determined on the basis of the effects of the water on the quality and yield of the crops, as well as the effects on drainage efficiency and characteristic changes in the soil [16]. This study aims to assess the quality of groundwater in Modjo river catchment for irrigation. Hence, the groundwater samples were collected from well and borehole situated at different site within the catchment to analyze for necessary parameters. Consequently, in-situ measurements such as; EC, pH and TDS were carried out in the field inventory using portable ( pH) meters, whereas major ions are analyzed in Sinana Agricultural Research Center Soil laboratory. The chemical analysis of the samples shows that Na-Ca-HCO3 water type in the recharge area, intermediate water type Ca-Mg-Na HCO3 in northern and central part of the area and Ca-Mg-HCO3 water type towards the east of the subbasin. Most of the water in the study area is clustered as Calcium-Sodium-Magnesium-Bicarbonate type, which is characterized by a high concentration of HCO3 and Ca. Generally water quality analysis shows that as the concentrations in the water sample is below the maximum allowable limits for irrigation (i.e.EC<2000 µS/cm and SAR<9) and therefore the groundwater could be used safely for irrigation.
灌溉农业依赖于足够的可用质量的水供应。含有杂质的水对植物生长有害,不宜灌溉。农业用水质量是根据水对作物质量和产量的影响,以及对土壤排水效率和特征变化的影响来确定的[16]。本研究的目的是评价Modjo河流域灌溉用地下水的水质。因此,从位于集水区不同地点的井和钻孔中采集地下水样本,分析必要的参数。因此,现场测量,如;土壤EC、pH和TDS在野外调查中采用便携式pH仪进行,主要离子在西纳那农业研究中心土壤实验室进行分析。样品化学分析表明,补给区为Na-Ca-HCO3水型,北部和中部为Ca-Mg-Na -HCO3中间水型,次盆东部为Ca-Mg-HCO3水型。研究区大部分水呈钙-钠-镁-碳酸氢盐型聚集,其特点是HCO3和Ca的浓度较高。总体水质分析表明,由于水样中的浓度低于灌溉的最大允许限值(即ec <2000µS/cm, SAR<9),因此地下水可以安全用于灌溉。

Purpose to determine the place of the smartphone by evaluating the possession and the use of medical applications in the practice of the professionals at the Mohamed VI University Hospital of Marrakech and hospital “Moulay Youssef Rabat” This is a prospective descriptive and mono-centric analytical study on health professionals working or performing their training at hospital structures during the 6 months of the study using a smartphone. Our study took place over a period of 6 months, from August 1, 2018 to January 31, 2019, is carried out on two sites. Within the Moulay Youssef Hospital Rabat CHR, Hospital mother and child Mohamed VI Hospital Marrakech hospital. A clear predominance of female 131 (65%) , with a sex ratio F / H of 0.51.with an average age of 34.4 years, with extreme ages between 60 and 18 years. We found that 149 (74.5%) were hospital professionals, 86 (43%) were medical students, 191 (95.57%) used French as their main language. - 142 (71%) use a smartphone and 125 (62.5%) use it in the medical prescription. Of the 200 professionals, 81% were convinced of the benefit of using Smartphones. The overflow of professional boundaries was highlighted as a disadvantage by 47% of the professionals.130 (65%) want more APPS communications and more than 50% were willing to pay between 50 and 200 MAD for medical APPS. In our study There is a statistically significant linear correlation between the age and the number of smartphone users during these 6 months (p = 0.023).There is a statistically significant linear correlation between professional status and number of smartphone uses during these 6months (p <0.001). Our study joins the data of the literature with an average of the number of use during these 6 months which is not statistically different according to the sex (p = 0.27). There is a statistically significant linear correlation between the average number of smartphone uses for medical purposes and the number of Smartphone usage during these 6 months (p <0.001). In our study, the average number of uses during these 6months is statistically different depending on the professionals we judge that it is beneficial (p = <0.01). The smartphone is a real tool in the practice of health professionals for optimal care of the patient. It would be interesting to develop formal assessment strategies and training in these medical applications for use with confidence in our context.

Carcinoma is the 2nd leading mortality in the U.S. Signs & symptoms include typically unspecific until the tumours metastasize. Hence, an urgency is there for quick, precise, and non-invasive carcinoma diagnosis, rapid detection, diagnosis, stage surveys, & forecasts. Saliva is a multi-structural fluid, found in the oral region, containing secretions from primary and minor salivary glands. Species can even be found in blood-present molecules including Deoxyribo Nucleic Acids, RNAs, hormones, metabolites, and microbiota. Recently, saliva testing received considerable interest in identifying specific biomarkers as sample collection and processing is quick, cost-effective, accurate and doesn’t put any distress on the patient. We examine recent salivary biomarkers of systemic carcinoma by separating them into genomically, transcriptomically, proteomically, metabolomic and microbially dependent forms.
癌症是美国第二大致死疾病,其体征和症状在肿瘤转移前通常不明确。因此,迫切需要快速、精确和非侵入性的癌症诊断、快速检测、诊断、分期调查和预测。唾液是一种多结构的液体,存在于口腔区域,含有主要和次要唾液腺的分泌物。物种甚至可以在血液中的分子中找到,包括脱氧核糖核酸、rna、激素、代谢物和微生物群。最近,唾液测试在识别特定生物标志物方面受到了相当大的兴趣,因为样本采集和处理快速、经济、准确,而且不会给患者带来任何痛苦。我们通过将其分为基因组学、转录学、蛋白质组学、代谢组学和微生物依赖形式来研究近期系统性癌的唾液生物标志物。

Diversity, population structures and regeneration status of gum- and resin- producing woody species, were assessed in 116 sample plots, each measuring 400 m2 and established along line transects. The data were collected in two selected districts, namely, Sherkole and Kurmuk in Benishangul-Gumuz National Regional State, one of the gum and resin belts in western Ethiopia. The gum- and resin-producing woody species had 1.04 and 0.7 diversity and 0.576 and 0.49 evenness values at Kurmuk and Sherkole districts, respectively. They accounted for 26% and 46% of the density, 51% and 58% of the basal area and 32% and 53% of the Importance Value Index of all the woody species, respectively. The gum- and resin- bearing woody species exhibited three patterns of population structure. The first pattern suggests good reproduction abilities of the species coupled with good recruitment of seedlings and their subsequent continuous growth to replace older individuals over time, indicating stable regeneration. About 61% of the gum- and resin- bearing woody species fall under this category. The other two patterns indicate hampered regeneration status of the woody species. Heavy grazing, conversion to crop land by small scale farming, gold mining, recurrent fire and climate change were mentioned as major bottlenecks of natural regeneration and recruitment. Policy, extension and research recommendations are discussed.
在116个样地(每个样地面积为400 m2)上沿样带建立样地,对产树胶和树脂的木本树种的多样性、种群结构和更新状况进行了评估。数据是在两个选定的地区收集的,即Benishangul-Gumuz民族区域州的Sherkole和Kurmuk,这是埃塞俄比亚西部的一个胶质和树脂带。库尔穆克区和舍尔科尔区产胶和产树脂木本树种的多样性分别为1.04和0.7,均匀度分别为0.576和0.49。它们分别占所有木本树种密度的26%和46%,基面积的51%和58%,重要值指数的32%和53%。含胶和树脂的木本树种表现出三种种群结构模式。第一种模式表明,该物种具有良好的繁殖能力,加上良好的幼苗招募和随后的持续生长,随着时间的推移取代老个体,表明稳定的再生。大约61%的含树胶和树脂的木本树种属于这一类。另外两种模式表明木本树种的再生状态受到阻碍。过度放牧、小规模耕作转为耕地、金矿开采、经常性火灾和气候变化被认为是自然再生和增收的主要瓶颈。讨论了政策、推广和研究建议。
