Cucurbita moschata is an edible member of the family Cucurbitaceae. The plant is commonly observed showing typical virus-like symptoms during the growing season in Akwa Ibom State, Nigeria. A total of 7 leaf samples showing typical virus-like symptoms were collected from C. moschata in different locations in Itu and Uyo Local Government, Akwa Ibom State. All the virus isolates used in this study were sap transmissible with a wide host range. The virus isolates irrespective of the place of collection were transmitted in a fore-gut manner by A. spiraecola. Aphis citricida did not transmit the viruses. All the virus isolates reacted positively to cucumovirus polyclonal antibody in antigen coated plate-ELISA (ACP-ELISA). Gel electrophoresis of the cDNA of the virus isolates produced 500 base pairs typical of Cucumber mosaic virus. The gene sequence analysis revealed that all the isolates had sequence homology of 95% and above with Cucumber mosaic virus (CMV) and are therefore considered strains of CMV. The results also showed that CMV isolates investigated in this study shared common ancestry, though belonging to different clusters. The results also indicated that CMV could be widespread and therefore a threat to C. moschata production in Itu and Uyo Local Government Areas of Akwa Ibom State. This is the first report of CMV infecting C. moschata in Akwa Ibom State, Nigeria. Further work should be carried out to cover the entire state.
Cucurbita moschata 是葫芦科的一种食用植物。在尼日利亚阿夸伊博姆州的生长季节，人们经常观察到这种植物出现典型的病毒样症状。研究人员在阿夸伊博姆州伊图和乌约地方政府的不同地点共采集了 7 份表现出典型病毒样症状的 C. moschata 叶片样本。本研究中使用的所有病毒分离株都具有树液传播性，宿主范围很广。无论采集地点如何，病毒分离株都是由 A. spiraecola 以前肠方式传播的。柠檬蚜不传播病毒。在抗原涂布平板-ELISA（ACP-ELISA）中，所有病毒分离物都与葫芦病毒多克隆抗体呈阳性反应。对病毒分离物的 cDNA 进行凝胶电泳，得到了 500 个典型的黄瓜花叶病毒碱基对。基因序列分析表明，所有分离物与黄瓜花叶病毒（CMV）的序列同源性在 95% 及以上，因此被认为是 CMV 的毒株。结果还显示，本研究调查的 CMV 分离物虽然分属不同的群组，但具有共同的祖先。结果还表明，CMV 可能广泛传播，因此对阿夸伊博姆州伊图和乌约地方政府地区的 C. moschata 生产构成威胁。这是尼日利亚阿夸伊博姆州首次报告 CMV 感染 C. moschata。应在全州范围内开展进一步的工作。

The effect of aqueous extract of Irvingia wombolu seeds on lipid profile and atherogenic indices in hyperlipidemic wistar rats was evaluated. Forty five (45) wistar rats were grouped into five groups of nine rats each. The animals were allowed seven days acclimatization period. Group one was the control group and it received normal rat chow and water throughout the study. Groups 2 to 5 were given high fat diet for 14 days after which they were fed with normal rat chow till the end of the study. At the end of the 14 days, group 2 was not treated while group 3-5 were treated with 250, 500 and 1000mg/kg body weight aqueous extract of Irvingia wombolu seed respectively for 28 days. The lipid profile of animals was assayed three times: first after 14 days induction period (phase 1) i.e day 0 of treatment, second was taken 14 days after treatment (phase 2), third was taken 28 days after treatment (phase 3).The study lasted for 49 days and distilled water was used as a vehicle for the extract.In phase 1, there was a significant decrease (p<0.05) in HDL (high density lipoprotein) level in all groups (2-5) compared to the control.there was a significant increase (p<0.05) in LDL ( low density lipoprotein), Total cholesterol, Triglyceride, VLDL (very low density lipoprotein), Non HDL, Cardic risk factor, Atherogenic coefficient, Atherogenic index of plasma levels in all groups (2-5) compared to the control. All doses of aqueous extract of Irvingia wombolu seed were able to increase HDL level and decrease other lipid profile parameters and atherogenic indices in hyperlipidemic rats. Thus, aqueous extract of Irvingia wombolu seed has antidyslipidemic potential.

Young seedlings of five tea clones under cultivation (318, 236, 68, BB35, and 143) and five from the germplasm), were collected from the Kakara Highland tea Plantations, Mambila Plateau, Taraba State. Seedlings were planted in fifty sample boxes to enable the seedlings to be established first before transplanting to the field. After the establishment, they were transported to Obudu Hills for investigation. The experiment was laid out in a randomized complete block design (RBCD) with 3 replications. Data collected on morphological traits were subjected to an analysis of variance (ANOVA) test. Multivariate analysis such as principal component analysis (PCA), hierarchical cluster analysis and correlation analysis were used to estimate genetic diversity between the tea plant clones. The result showed that the tea clones survived the first two months after transplanting. However, subsequently, the percentage of survival was reduced. Results from the morphological studies revealed that the accessions differed significantly (p>0.001) in all evaluated traits except for leaf width and dry biomass. Three principal components were identified based on eigenvalues; the first principal component contributed 44.18% of the total variation with an eigenvalue of 3.977, the second principal component accounted for 24.36% with total eigenvalue of 2.193 while PC3 accounted for 15.345% of the total variation with eigenvalue of 1.381. Cluster analysis showed that the evaluated tea clones were grouped into two main clusters containing sub-clusters. The high genetic diversity identified in Camellia sinensis clone in the study will serve as a guide in breeding, genetic improvement, utilization and conservation of this important nutritional and medicinal plant species.

Background: Chronic inflammation, a factor for high mortality, persists throughout the pregnancy period of women living with human immunodeficiency Virus (HIV). Aim: To determine whether pregnancy alone or the combined effects of HIV and pregnancy are the sources of the inflammation, this study evaluated the predictive variables for inflammation, lymphocyte ratio (NLR), and Platelet-Lymphocyte Ratio (PLR). Materials and Methods: A population of 128 women, aged 15-49 years were grouped into 4; Group A- 32 HIV positive and pregnant, Group B- 32 HIV negative and pregnant, Group C- 32 HIV positive not pregnant, Group D- 32 HIV negative not pregnant (control group). Differential white blood cell and platelet count methods were used to determine the neutrophil (N), Lymphocyte (L) and platelet (P) counts. The ratio calculation method was used to derive the NLR and PLR. Results: NLR was significantly higher for group A (2.62±0.41) compared to groups B (2.25 ± 0.18); C (0.95 ± 0.07); D (1.68 ± 0.19) at p ≤ 0.00. However, the NLR of groups A and B (p ≤ 0.05) were not significantly different, PLR was significantly higher for group A (9.86±1.12) compared to groups B (6.65 ± 1.12); C (5.35 ± 0.47); D (6.34 ± 0.43). There was no significant difference in blood pressure across the groups, significant difference was however observed in their Body Mass Index. Conclusion: Hence, Inflammation may have been caused by pregnancy alone.
背景：慢性炎症是导致高死亡率的一个因素，感染人类免疫缺陷病毒（HIV）的妇女在整个孕期都存在慢性炎症。目的：为了确定是妊娠本身还是 HIV 和妊娠的共同作用导致了炎症，本研究评估了炎症、淋巴细胞比值（NLR）和血小板-淋巴细胞比值（PLR）的预测变量。材料与方法将 128 名 15-49 岁的女性分为 4 组：A 组--32 名 HIV 阳性且怀孕；B 组--32 名 HIV 阴性且怀孕；C 组--32 名 HIV 阳性未怀孕；D 组--32 名 HIV 阴性未怀孕（对照组）。采用白细胞和血小板计数差法测定中性粒细胞（N）、淋巴细胞（L）和血小板（P）计数。采用比值计算法得出 NLR 和 PLR。结果A 组（2.62±0.41）的 NLR 明显高于 B 组（2.25±0.18）、C 组（0.95±0.07）和 D 组（1.68±0.19），P≤0.00。然而，A 组和 B 组的 NLR（p ≤ 0.05）无显著差异，A 组的 PLR（9.86±1.12）显著高于 B 组（6.65±1.12）；C 组（5.35±0.47）；D 组（6.34±0.43）。各组的血压没有明显差异，但体重指数有明显差异。结论因此，炎症可能仅由妊娠引起。

Benzo [a] pyrene is the main representative of polycyclic aromatic hydrocarbons, and has been repeatedly found in the air, surface water, soil, and sediments. Human exposure to Benzo [a] pyrene is therefore common. Benzo (a) pyrane (BaP) which is mainly presented in newspaper ink and inhibits the function of the thyroid and other endocrine glands of the human system, due to several disorders that occur in the human body. Healthy mature male mice Mus musculus having weight of 125 ± 5 gm were used for the experiments. The effects of a Benzo (a) pyrene (0.65mg/25g body weight/twice in a week) during experimental periods of 60 and 90 days in male mice Mus musculus showed significant difference in body weights compared to control. We assessed the hormonal estimation of thyroid treated with Benzo (a) pyrene by using an appropriate ELISA assay kit and histopathological changes were observed under a light microscope (magnifications 100X) in the thyroid tissue of male mice Mus musculus exposed to BaP after 60 and 90 days. During the study, we observed that in treated mice thyroid hormone concertation was affected the structure of the thyroid follicles was disturbed and epithelial cells were necrotic compared with the control mice which indicates that the BaP may lead to changes in the thyroid morphology as well as secreted hormone concentration in exposed treated male mice.

Background: Human umbilical cord mesenchymal stem cells (hUCMSCs) represent a valuable and versatile cell type derived from the umbilical cord tissue of newborns. These cells exhibit diverse characteristics, including multipotent differentiation potential and low immunogenicity. hUCMSCs hold promise for clinical applications, yet concerns persist regarding their chromosomal stability. This study employs short tandem repeat (STR) analysis to assess genomic integrity. By focusing on chromosomal stability, the study aims to enhance confidence in the clinical viability of hUCMSCs, contributing to their safe and effective use in regenerative medicine. hUCMSCs were extracted from healthy newborn umbilical cords using tissue block adherence and enzyme digestion. The third generation of hUCMSCs undergoes biological characterization and quality checks, including examinations of cell morphology, viability, growth curves, surface markers, cell cycle, and multi-lineage differentiation potential. The result of the present study shows that hUCMSCs exhibit mesenchymal stem cell characteristics, with robust growth and high viability. Positive surface markers are expressed at rates exceeding 95%, while negative markers are ≤2%. Cell karyotyping analysis, STR spectrum identification, and chromosomal microarray analysis confirm genetic stability. Microbial testing shows the absence of contaminants, and immunological studies demonstrate the immunomodulatory capabilities of hUCMSCs. Specific residues, such as trypsin, were not detected. In conclusion, hUCMSCs produced under strict GLP and GMP conditions meet the quality guidelines for clinical application in various stem cell therapies. The findings support the clinical application of hUCMSCs in various medical contexts.

The present study reports experimental data on substrate specificity and some properties of the extracellular enzyme with oxidase activity isolated from the mycelium of the higher fungus Neonothopanus nambi IBSO 2391 by treating the biomass with (beta) -glucosidase. Gel-filtration chromatography showed that molecular weight of the isolated enzyme was 80 kDa. Spectral analysis did not reveal any chromophore components in the enzyme. The extracellular oxidase of the basidiomycete N. nambi IBSO 2391 was active with most of the aromatic compounds chosen as model substrates. An important fact is that the enzyme exhibited catalytic activity with no hydrogen peroxide or any other mediators added to the reaction mixture. The highest activity of the enzyme was observed in reactions with veratryl alcohol and hydroquinone. In reactions with guaiacol and aromatic amines (diaminobenzidine, o-dianisidine), the level of activity of the extracellular oxidase was considerably lower – by a factor of 2.5–3.5. In reactions with resorcinol, phenol, and caffeic acid, the catalytic efficiency of the enzyme was no greater than 6% of its activity with veratryl alcohol. Kinetic parameters of enzymatic reactions were determined for the most efficiently oxidized substrates. The addition of the chelating agent of divalent metal ions (EDTA) did not affect the activity of the extracellular oxidase from the fungus N. nambi IBSO 2391, indicating the absence of divalent metal ions in the molecule of the enzyme. At the same time, addition of the SH reagent (DTT) increased catalytic efficiency of the enzyme. The study showed that the extracellular oxidase of the fungus N. nambi IBSO 2391 functions in wide ranges of temperature and pH of the reaction medium, showing the highest catalytic activity at temperatures between 22 and 35 °C and pH 6.0. Results obtained in the current study provide the basis for studying potential uses of the isolated enzyme in biomedical analytics and bioremediation.
本研究报告了从高等真菌 Neonothopanus nambi IBSO 2391 的菌丝体中分离出来的具有氧化酶活性的胞外酶的底物特异性和一些特性的实验数据。凝胶过滤色谱法显示，分离出的酶的分子量为 80 kDa。光谱分析没有发现该酶中有任何发色团成分。基枝菌 N. nambi IBSO 2391 的胞外氧化酶对大多数被选为模型底物的芳香族化合物具有活性。一个重要的事实是，在反应混合物中不添加过氧化氢或任何其他介质的情况下，该酶也表现出催化活性。在与藜芦醇和对苯二酚的反应中，酶的活性最高。在与愈创木酚和芳香胺（二氨基联苯胺、邻二氨基联苯胺）反应时，细胞外氧化酶的活性水平要低得多--低 2.5-3.5 倍。在与间苯二酚、苯酚和咖啡酸的反应中，酶的催化效率不超过其与藜芦醇活性的 6%。对氧化效率最高的底物测定了酶反应的动力学参数。添加二价金属离子螯合剂（EDTA）不会影响真菌 N. nambi IBSO 2391 胞外氧化酶的活性，这表明酶分子中不存在二价金属离子。同时，加入 SH 试剂（DTT）可提高酶的催化效率。研究表明，真菌 N. nambi IBSO 2391 的胞外氧化酶在反应介质的温度和 pH 值范围很宽的情况下都能发挥作用，在温度为 22 至 35 °C、pH 值为 6.0 时催化活性最高。本研究获得的结果为研究分离出的酶在生物医学分析和生物修复方面的潜在用途提供了基础。

Gel-filtration chromatography showed that molecular weight of the isolated enzyme was 80 kDa. Spectral analysis did not reveal any chromophore components in the enzyme. The extracellular oxidase of the basidiomycete N. nambi IBSO 2391 was active with most of the aromatic compounds chosen as model substrates. An important fact is that the enzyme exhibited catalytic activity with no hydrogen peroxide or any other mediators added to the reaction mixture. The highest activity of the enzyme was observed in reactions with veratryl alcohol and hydroquinone. In reactions with guaiacol and aromatic amines (diaminobenzidine, o-dianisidine), the level of activity of the extracellular oxidase was considerably lower – by a factor of 2.5–3.5. In reactions with resorcinol, phenol, and caffeic acid, the catalytic efficiency of the enzyme was no greater than 6% of its activity with veratryl alcohol. Kinetic parameters of enzymatic reactions were determined for the most efficiently oxidized substrates. The addition of the chelating agent of divalent metal ions (EDTA) did not affect the activity of the extracellular oxidase from the fungus N. nambi IBSO 2391, indicating the absence of divalent metal ions in the molecule of the enzyme. At the same time, addition of the SH reagent (DTT) increased catalytic efficiency of the enzyme. The study showed that the extracellular oxidase of the fungus N. nambi IBSO 2391 functions in wide ranges of temperature and pH of the reaction medium, showing the highest catalytic activity at temperatures between 22 and 35 °C and pH 6.0.

Evaluation and development of potent anti-cancer treatments have been a global interest of research due to significant rise in cancer as well as related diseases. Many herbal extracts have shown the potential to be used in the treatment of such diseases. In order to evaluate the anticancer features of Moringa oleifera (ME), Clitoria ternatea (CE), and Coccinia grandis (CCD), this study was carried out using various cell lines i.e. L-929, Vero, L-132, Raw 264.7, and Balb 3T3 with six different concentrations of each test substance by using MTT cell viability Assay. Additionally, in-vitro studies are performed using these test items and claims are being done that these test items are playing a pivotal role either treatment of Alzheimer's diseases (AD) and Parkinson's disease (PD) or decreasing the severity and incidences of such neurodegenerative diseases. Globally, an average life expectancy rises, so does the severity of these conditions as well. Hence, this study was also aimed to determine whether any supportive changes are showed on different cell lines or not. In contrast to normal cells, the test substances revealed possible anti-cancer characteristics when exposed to carcinoma cell lines based on the data obtained in this study. The results indicated that ME, CE and CCD are effective against cancer cells; hence based on the results of these study, it could be concluded that that the data of the present study supports the interpretation that these test items have significant effects either in treatment or slowing down the clinical signs of PD and AD under the conditions and procedures followed in the present study. Based on the results of cell viability results it could also be concluded that the test items are safer to use up to the concentrations of 500 µg/mL.
