High intake of plant foods is associated with lower risk of chronic diseases as suggested by epidemiological evidence. This study aimed to investigate the anti-inflammatory potential of polyphenol rich fraction of Ipomoea batatas leaf extract and the compounds possibly responsible for the activity using LCMS. The anti-inflammatory studies were carried out in vitro by protein denaturation technique. The result shows significant different (p<0.05) percentage inhibition of denaturation 90.59% at 1000 μg/ml of the extract compared to the standard drug (declofenac) 95.12% at 1000 μg/ml. The LCMS profiling of the extract revealed the presence of many metabolites (polyphenols) such as chrogenic acid, myricetin, furocoumarinic acid, aromadendrin, naringenin, 4,5-dicaffeolquinic acid and abietinol among others. The presence of these metabolites could be the reason for the anti-inflammatory effect of the extract observed. This implies that the plant can be exploited for its medicinal, therapeutic properties and possibly used to reduce the risk of many chronic diseases. Keyword: Anti-inflammatory activity, Protein denaturation technique, Mother delight, LCMS, Phytochemicals.
流行病学证据表明,大量摄入植物性食物可降低患慢性病的风险。本研究旨在利用LCMS法研究山茱萸叶提取物中富含多酚的部分的抗炎活性及其可能的作用机制。采用蛋白变性技术进行体外抗炎研究。结果表明,在1000 μg/ml时,该提取物对变性的抑制率为90.59%,与标准药(癸芬酸)在1000 μg/ml时的抑制率为95.12%有显著性差异(p<0.05)。提取液的LCMS谱分析显示存在多种代谢物(多酚),如绿原酸、杨梅素、呋喃香豆素、芳香腺嘌呤、柚皮素、4,5-二咖啡因喹啉酸和枞醇等。这些代谢物的存在可能是观察到的提取物具有抗炎作用的原因。这意味着该植物可用于其药用和治疗特性,并可能用于减少许多慢性疾病的风险。关键词:抗炎活性,蛋白质变性技术,Mother delight, LCMS,植物化学

The control of Spoladeare curvalis, a major pest of amaranth plant, has been through the use of synthetic pesticides which have been reported to have detrimental effects. This study was aimed at assessing the larvicidal potency of B. thuringiensis against the larvae of Spoladea recurvalis on amaranth plant. The assessment of the larvicidal potency of B. thuringiensis isolates from cow range land and refuse dump sites in Zaria metropolis habouringCry1 gene (CR2, CR4, RD1) was carried out by spraying spore crystal mixture of B. thuringiensis isolates on amaranth plants infested with Spoladea recurvalis larvae. The mortality of S. recurvalis larvae, under a screen house were assessed after 24, 48 and 72hours of exposure to the spore crystal mixture of B. thuringiensis isolates. Spore crystal mixtures of B. thuringiensis isolates were effective in causing larvae mortality with more than 60% mean mortality rate of S. recurvalis larvae after 72hours of exposure. The mortality rate of Spoladea rescurvalis increased with increase in exposure period. Spore crystal mixture of Bacillus thuringiensis isolates should be considered as an alternative to synthetic pesticides for the control of Spoladea recurvalis larvae on amaranth plant. Keywords: Bacillus thuringiensis; spore; larvae; amaranth; larvicidal.
对苋属植物的一种主要害虫——曲斑孢虫的控制一直是通过使用合成杀虫剂来进行的,据报道,这种杀虫剂具有有害的效果。研究了苏云金芽孢杆菌对苋菜反刍孢子虫幼虫的杀虫效果。通过将含有cry1基因(CR2、CR4、RD1)的苏云金芽孢杆菌分离株孢子结晶混合物喷施在有反叶孢子虫幼虫侵染的苋菜植株上,评价了该分离株的杀虫效果。分别于苏云金芽孢杆菌孢子结晶混合物暴露24、48和72小时后,在纱窗下测定了苏云金芽孢杆菌幼虫的死亡率。苏云金芽孢杆菌分离株的孢子晶体混合物对苏云金芽孢杆菌幼虫有明显的杀伤作用,暴露72小时后,平均死亡率超过60%。随着暴露时间的延长,黑穗虫的死亡率呈上升趋势。苏云金芽孢杆菌分离株的孢子结晶混合物可作为合成农药的替代品,用于防治苋菜上的反曲孢子蝇幼虫。关键词:苏云金芽孢杆菌;孢子;幼虫;苋菜;杀灭幼虫。

This study was aimed at investigating the potential use of biosurfactant-expressing bacterial isolates in the biodegradation of premium motor spirit (PMS) at various concentrations (100-100,000ppm). The biosurfactant-expressing bacteria were isolated from mechanic workshop in Malumfashi, Katsina, Nigeria using standard techniques. The isolates identified belonged to the genera Acinetobacter, Bacillus, Micrococcus, Pseudomonas and Stenotrophomonas. These isolates were screened for biosurfactant expression using drop collapse, haemolysis, oil–water behavior assays and emulsification index test. Positives isolates were investigated for PMS degradation by growing the isolates on mineral salt media supplemented with (0.1ml) premium motor spirit (PMS) as sole source of carbon. Although, higher total hydrocarbon degrading bacterial counts were obtained from soils where isolates positive for biosurfactant expression are predominant, there was no statistically significant difference between isolate source using Kruskal-Wallis H test (p = 0.67). The isolates Bacillus velezensis and Stenotrophomonas maltophilia were positive for biosurfactant-production potential using drop-collapse, β-haemolysis, oil spreading, and emulsification index and drop collapse tests with higher tolerance to PMS at concentrations up to 100,000 ppm. Statistical analysis using multiple-comparison analysis of variance (ANOVA) confirmed that the isolates exhibited varying PMS degradation response (p = 0.0066); furthermore, the tolerance of the bacteria to the PMS is dose-dependent (p = 0.00012). Post-hoc analysis using Tukey’s test identified Bacillus velezensis as the most efficient biosurfactant-producing and hydrocarbon degrading isolate (p = 0.0264 and 0.0034); moreover, the threshold concentration for high PMS tolerance was found to be 1000ppm and above (p = 0.0174, 0.0008 and 0.0001).These isolates’ ability to grow on mineral salt media supplemented with PMS as a sole source of carbon presents a veritable avenue for exploitation in biotechnology, towards biosurfactants-mediated bioremediation of hydrocarbon pollutants in oil contaminated soils. Keywords: Biodegradation, Petroleum Hydrocarbons, Premium Motor Spirit
本研究旨在探讨表达生物表面活性剂的细菌分离物在不同浓度(100-100,000ppm)的优质汽酒(PMS)的生物降解中的潜在用途。采用标准技术从尼日利亚卡齐纳Malumfashi的机械车间分离到表达生物表面活性剂的细菌。分离株属不动杆菌属、芽孢杆菌属、微球菌属、假单胞菌属和窄养单胞菌属。采用滴缩法、溶血法、油水行为法和乳化指数法对分离菌株进行生物表面活性剂表达筛选。通过在添加(0.1ml)优质汽油机(PMS)作为唯一碳源的无机盐培养基上培养,研究了阳性菌株对PMS的降解能力。虽然在生物表面活性剂表达阳性的土壤中获得了更高的总烃降解细菌计数,但使用Kruskal-Wallis H检验,不同来源的分离菌之间没有统计学差异(p = 0.67)。通过滴塌试验、β-溶血试验、油扩散试验和乳化指数试验,分离物velezensis芽孢杆菌和嗜麦芽窄养单胞菌的生物表面活性剂生产潜力呈阳性,对浓度高达100,000 ppm的PMS具有更高的耐受性。采用多重比较方差分析(ANOVA)进行统计分析,证实分离菌株表现出不同的PMS降解反应(p = 0.0066);此外,细菌对PMS的耐受性是剂量依赖性的(p = 0.00012)。采用Tukey’s试验的事后分析发现,velezensis是最有效的生物表面活性剂产生和碳氢化合物降解分离物(p = 0.0264和0.0034);高PMS耐受阈值浓度为1000ppm及以上(p = 0.0174、0.0008和0.0001)。这些分离物在矿物盐培养基上生长的能力,补充了PMS作为唯一的碳源,为生物技术的开发提供了一条真正的途径,即生物表面活性剂介导的石油污染土壤中碳氢化合物污染物的生物修复。关键词:生物降解,石油烃,优质汽油

Exopolysaccharides (EPS) are exogenous bacterial sugar polymers with many applications in dairy, pharmaceutical and cosmetic industries, using it as thickeners, stabilizers, and gelling agents. The study aimed to screen for potential exopolysaccharide producers from Lactobacillus spp. isolated from locally fermented milk (nono). Twenty-five nono Samples were collected from Wambai market, Kano. Lactic acid bacteria were isolated using de Man Ragosa and Sharpe Agar. Isolates were identified by API 50 CHL kit and web and screened for EPS production in which the EPS was extracted and quantified using the phenol-sulphuric method. Next, the influence of carbon source (Glucose, Sucrose and Lactose) and concentrations on EPS were evaluated on some of the isolated strains. The functional groups of the EPS were confirmed using FTIR. The isolated Lactobacillus spp. were all Gram positive, catalase and oxidase negative, API identification yielded; Lactobacillus acidophilus 1, Lb. brevis 1, Lb. fermentum, Lb. paracasei ssp paracasei, Lb. acidophilus 3. Ten isolates yielded EPS in the range of 248.33mg/l - 07.83mg/l. The FTIR analysis of extracted EPS produced peaks around 3,300–881cm-1. Hence the study has brought to light the presence of potential EPS producing LAB in nono, which could be further exploited to harness their potential.

In a bid to determine the level of antimicrobial resistance among bacterial pathogens feared to be nosocomially transmitted in some hospitals, Firstly, patients of HCAI was identified and followed-up accordingly with standardized questionnaire in the hospitals. Sample were collected for bacteriological assay using Culture and biochemical methods for the investigation of bacteria associated with nosocomial, Antibiogram pattern was assessed by Disk diffusion as to mark the resistant ones and presence of gene encoding for mecA and blaZ with the aid of PCR. At AKTH, A total of 63% of isolates were Gram-positive while 37% were Gram-negative bacteria. S. aureus were the most common isolates with frequency of 37%. Most of all the Gram-positive isolates were resistant to cefuroxime (30μg) and Amoxicillin (10μg) while they shown high sensitivity to other antibiotics tested against them. Only 18% of S. aureus are suspected MRSA. Most of Gramnegative isolates were found to be resistant to amoxicillin (10μg) 100%, gentamicin (10μg) 71% and chloramphenicol (30μg) 57%. At MMSH, 86% of the isolates were Gram-positive while 14% were Gram-negative bacteria. S. aureus, 42% were the most common isolates. All the isolates were resistance to cefuroxime and Amoxicillin (10μg) while they showed sensitivity to other tested antibiotics. while most shows sensitivity to other tested antibiotics. Only 24% of S. aureus were MRSA. 63% of the tested MRSA were mecA positive while 100% were blaZ positive. The high rates of resistome of isolates represent a substantial threat to the public where well-structured and continuous surveillance system for antimicrobial resistance is needed to encourage the monitoring of antimicrobial therapy.

Malaria remains one of the greatest concerns for the African population. To curb malaria, certain strategies need to be adopted like a quick diagnosis of the parasite within the human body, maintenance of proper environmental hygiene and use of other control methods. Diagnosis of malaria is often achieved using Microscopy, Rapid Diagnostic Test and Molecular Technique. This study aims to compare the effectiveness of Microscopy and Rapid Diagnostic Testing in diagnosing malaria infection in patients at the General Hospital, Ijebu-Igbo, Ogun State, Nigeria which also falls under a malaria-endemic region using 150 study participants. Blood samples were collected from study participants having malaria symptoms using ethylenediamine tetra-acetic acid (EDTA) container. The screening was done using microscopy method and Rapid Diagnostic Test. The data generated were analyzed using the Statistical Package for the Social Sciences (SPSS) version 19. The statistical parameter that was used for the analysis of the data was Pearson's Chi-Square Test, P at 0.05. The result shows the prevalence of malaria obtained through microscopic examination was 120 (80%) considerably more than RDT 54 (36%). These findings confirmed that microscopy is the gold standard in malaria diagnosis due to its high sensitivity, which allows it to detect parasites even at low counts. However, RDT has a specificity of 93.3% and a sensitivity of 92.2%, indicating that it is also effective when the parasite load is high.

疟疾仍然是非洲人民最关心的问题之一。为了遏制疟疾,需要采取某些战略,如快速诊断人体内的寄生虫,保持适当的环境卫生和使用其他控制方法。疟疾的诊断通常使用显微镜、快速诊断试验和分子技术。这项研究的目的是比较显微镜和快速诊断测试在尼日利亚奥贡州Ijebu-Igbo总医院诊断疟疾感染的有效性,该医院也属于疟疾流行地区,研究人员使用了150名研究参与者。使用乙二胺四乙酸(EDTA)容器采集有疟疾症状的研究参与者的血样。采用镜检法和快速诊断试验进行筛选。生成的数据使用社会科学统计软件包(SPSS)第19版进行分析。用于数据分析的统计参数为皮尔逊卡方检验,P = 0.05。结果显示,镜检所得疟疾流行率为120(80%),显著高于RDT 54(36%)。这些发现证实,显微镜是疟疾诊断的金标准,因为它具有高灵敏度,即使在低计数的情况下也能检测到寄生虫。然而,RDT的特异性为93.3%,敏感性为92.2%,表明在寄生虫载量高的情况下也有效。然而,与用于疟疾诊断的RDT试剂盒相比,显微镜分析显示灵敏度更高(100%);然而,RDT可能是一种有用的快速干预工具,以避免与延迟诊断相关的危险。关键词:疟疾;流行;诊断

Mint herbs have been reported to possess several biological effects, and the dried leaves are traditionally used for herbal tea or medicine. Extraction of plant materials was by maceration method. Both preliminary qualitative screening of phytochemicals and Liquid Chromatography Mass Spectrometer (LCMS) profiling revealed many useful metabolites. The phytochemicals include: Saponin, Carbohydrate, Alkaloids, Cardiac glycoside, and Steroid. Some LCMS compounds among others were also evaluated such as Quassin, Epioxylubimin, furocoumarinic acid glycoside and Dioctylamine. The antimicrobial activity of Mentha piperita extract against some food-borne pathogens such as Escherichia coli, Salmonella spp., Enterobacter spp. and Staphylococcus aureus were evaluated using agar well diffusion method at different concentrations ranging from 2000 µg/ml - 250µg/ml. The results revealed that hexane mint extracts had activity against the bacterial isolates. The highest activity was against E. coli (11.50 ±1.50) while the least activity was against Enterobacter spp (6.14 ± 0.13). The potential bioactive metabolites identified could be responsible for the antimicrobial activities observed. These findings have thus proven that Mentha piperita is more effective against E. coli. Therefore this extract could be used in the control and prevention of many food-borne pathogens and can be of importance in developing new biopreservatives.

The purpose of this study is to evaluate the nutrients, anti-nutrients and minerals composition of edible grasshopper (Chorthippus brunneus), locus beans and soya beans. The evaluations of nutrients and anti-nutrient composition of Chorthippus brunneus, Parkia biglobosa and Glycine max were analyzed using standard methods of A.O.A.C. and Kjedahal methods. The proximate analysis revealed that crude protein ranged between 24.667±3.512 to 39.561±2.553 with Chorthippus brunneus having the highest value and Parkia biglobosa and Glycine max having the lowest values. The Chorthippus brunneus had a considerable low carbohydrate contents compared to P. biglobosa and G. max carbohydrate value. However, the mean energy/caloric values ranged from 474 to 522 Kcal/Kg. Crude fat values were moderate, ranging from 11.763±1.035 to 15.26±0.761 with G. max having the highest value and C. brunneus the lowest. The anti-nutrients of the insects and the legumes were generally below toxic level in man. Moisture, ash and crude fibre were very high in C. brunneus compared to Parkia biglobosa and Glycine max. These Chorthippus brunneus therefore, could serve as additional promising sources of protein and fat for poultry and teeming population. The mineral compositions of the inscts (mg/kg) were considerably lower than that of locus beans and soya beans. Key: Chorthippus brunneus,Glycine max, Nutritional composition, Parkia biglobosa

Ebola Virus Disease (EVD) a deadly disease that affect human and apes like gorilla, chimpanzee antelopes and so on. The causative virus is found mostly in Africa. It had been uncovered first in mid 1970s on the brink of the River of Ebola village. Since from the primary inception of the strange disease in Democratic Republic of Congo, there has been a periodic outbreak of the disease in some African countries, affecting many people within the region. A systematic review was conducted using Google search Engine, Cochrane database systemic review (CDSR), Centre for Disease Control and prevention and World Health Organization EVD report Databases. The 2014-2016 Ebola outbreaks in West Africa were the most important and most complex, which began in Guinea and spread to Liberia, Nigeria and Sierra Leone. Before the disease is contained, it kills about 11,000 people and quite 28,000 people being affected from it first mid 1970s detection to late 2016. The virus is transmitted from fruit bat in touch of with other animals and passes on the infection to humans through handling infected, dead or sick animals found within the forest or through direct contact with bats. Human to human transmission occurs through direct contact with the blood, secretions and other body fluids. Symptoms of the virus are: sudden onset of fever, fatigue, muscle pain, headache, sore throat, vomiting, diarrhea, rash, impaired kidney and liver function, and bleeding from body openings. Recent advancements have been carried out in the form of effective Ebola Virus Vaccine Inmazeb and Ebanga for Zaire Ebola Virus and anti-Ebola virus drug rVSV-ZEBOV (Ervebo). However, the rapid geographic propagation, non-specific clinical presentation, lack of adequate vaccine and specific diagnostic assay are the possible challenges to combat the dreaded public health menace of Ebola Virus Disease. Key Words: Ebola Virus, Disease, Transmission, Treatment, Vaccine
埃博拉病毒病(EVD)是一种致命的疾病,影响人类和大猩猩、黑猩猩、羚羊等猿类。这种致病病毒主要在非洲发现。它于20世纪70年代中期首次在埃博拉村的河边被发现。自从这种奇怪的疾病最初在刚果民主共和国出现以来,这种疾病在一些非洲国家定期爆发,影响到该区域内的许多人。采用Google搜索引擎、Cochrane数据库系统评价(CDSR)、美国疾病控制与预防中心和世界卫生组织EVD报告数据库进行系统评价。2014-2016年西非的埃博拉疫情是最重要和最复杂的,始于几内亚,蔓延到利比里亚、尼日利亚和塞拉利昂。在这种疾病得到控制之前,从20世纪70年代中期首次发现到2016年底,它导致约1.1万人死亡,近2.8万人受到影响。该病毒通过果蝠与其他动物接触传播,并通过处理在森林中发现的受感染、死亡或生病的动物或通过与蝙蝠直接接触将感染传染给人类。人与人之间的传播是通过直接接触血液、分泌物和其他体液发生的。该病毒的症状是:突然发热、疲劳、肌肉疼痛、头痛、喉咙痛、呕吐、腹泻、皮疹、肾脏和肝脏功能受损以及身体开口出血。最近取得的进展是针对扎伊尔埃博拉病毒的有效埃博拉病毒疫苗Inmazeb和Ebanga以及抗埃博拉病毒药物rVSV-ZEBOV (Ervebo)。然而,快速的地理传播、非特异性临床表现、缺乏足够的疫苗和特异性诊断检测是抗击埃博拉病毒病可怕的公共卫生威胁可能面临的挑战。关键词:埃博拉病毒,疾病,传播,治疗,疫苗

Biofloc Technology utilizes the addition of carbon sources to fish culture systems to allow the growth of bacteria, as well as aggregation of dead organic matter in the fish culture systems thereby permit continuous use of water. The use of biofloc for C. gariepinus culture has evaluated the growth, feed conversion and water quality. This experiment was conducted to evaluate the effects of carbon sources on the haematological parameters of catfish in the biofloc system. The biofloc system was set-up at the Biological garden of Umaru Musa Yar’adua University, Katsina. A total of two hundred (200) fingerlings catfish with an average weight of 8.45 ± 1.6 g were randomly distributed in eight (8) plastic tanks at stocking densities of 1g/m3 . Three carbon sources namely; corn flour, rice bran, and sorghum flour were used to support the flocculation and growth of catfish in the system. The fishes were fed uniformly with a commercial diet ad-libitum. After six weeks rearing period, the survival of fish in all treatments was not significantly different (p <0.005); control (94%); corn-flour (90%), sorghum flour (98%) and rice bran (96%). Total weight gain was significantly higher (p<0.005) in corn-flour biofloc treatment. The blood sample collected for haematological analysis showed a significant difference (p˂ 0.05) in the mean blood parameters with respect to park cell volume (PCV), white blood cell (WBC), and haemoglobin (mg/l) values. The PCV of the rice bran treatment (18.00%) was significantly lower (p˂0.05) compared with other treatments. White blood cell (WBC) was significantly higher in rice bran treatment (p ˂ 0.05). The result indicated that corn-flour and sorghum could be used as the carbon source in the biofloc system with no effect on haematological parameters.
