Siam plant (Chromolaena odorata) is a plant with a characteristic aromatic smell, since ancient times, had been of interest for medical purposes in the local parlance and had been reported to be used in tradition medicine as antispasmodic, antiprotozoal, anti trypanosomal, antibacterial, antifungal, antihypertensive, anti-inflamatory, astringent, diuretic and hepatotropic agent. The aim of this study is to assess the histological impact of Siam weed on liver damage produced by Cadmium in adult Wistar rats. A total of twentyfive albino Wistar rats were obtained for the experiment. The rats were ..read more

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 vi ..read more

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 10 ..read more

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. M ..read more

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 ..read more

Mammea africana, a medicinal plant, used in ethnomedicine for the treatment of malaria, diabetes, poisoning and inflammatory diseases was investigated for cytotoxic and genotoxic effects on the root meristem cells of Allium cepa. Onion bulbs were exposed to 2.5 mg/mL, 5mg/mL, and 10 mg/mL concentrations of the stembark extract for macroscopic and microscopic analysis. Tap water was used as a negative control and Methotrexate (0.1 mg/mL) as a positive control. There was statistically significant (p< 0.05) inhibition of root growth depending on concentration by the extract when compared with ..read more

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) dur ..read more

Aims: This study investigated the antimicrobial resistance profile and extended spectrum beta-lactamase resistance genes in Escherichia coli of from urine of patients sourced from General Hospital, Karshi, Abuja, Nigeria. Study Design: Cross-sectional study. Place and Duration of Study: Department of Microbiology, Nasarawa State University, Keffi, between August 2022 and February 2023. Methodology: A total of 120 samples were collected from patients. Escherichia coli was isolated from the samples using standard microbiological methods. Antibiotic susceptibility testing was evaluated as describ ..read more

Cancer, a multifactorial disorder, arises due to defect in genetic makeup and exposure to unfavourable environmental conditions. Oral cancer, a life-threatening cancer worldwide, arises in the oral cavity due to ill-habits such as tobacco smoking and chewing. Monitoring body weight is an essential aspect of any preclinical study, including DMBA-induced oral carcinoma rat models and models with potential therapeutic interventions like Zingiber and piper feeding. Changes in body weight, feeding, water intake can provide valuable insights into the general health and physiological effects of the e ..read more

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 ..read more
