Hodgkin lymphoma is a rare neoplasm of the lymphatic system, representing one of the most common cancers in young adults. It is characterised by a low number of malignant cells derived from B-lymphocytes and an extensive microenvironment. We used Scopus, Web of Science and PubMed databases with search descriptors; “Hodgkin* lymphoma“ and “Hodgkin* disease”. The common bibliometric indicators were applied. We retrieved a total of 18,304 articles within 2002 and 2022. The growth pattern showed a saturated pattern, with the linear and exponential plots coinciding. A small number of authors were responsible for the majority of the publications, with a transience index of 71.84%. The Bradford core consisted of 32 journals, with Leukemia and Lymphoma being at the top. The most productive institutions were resident in United States with the University of Texas MD Anderson Center at the helm. The United States was found to be the most productive country. Engert A. was the most productive author. Scientific production in Hodgkin lymphoma was found to be saturated with a high transience index. This study provides a reference for oncologists, epidemiologists, funders, policy decision makers, academics, and Hodgkin lymphoma researchers.

The declining productivity of agricultural soils in Nekede, Imo State, necessitates a functional assessment of their fertility status for sustainable crop production. This study evaluated and classified the fertility capability of soils in the Nekede area using the Fertility Capability Classification (FCC) system. Soil samples were collected from five distinct locations at two depths (0–20 cm and 20–40 cm) using a stratified systematic sampling design. Samples were analyzed for key physical and chemical properties following standard laboratory procedures. Results indicated that soils are predominantly sandy loam with high sand content (>75%) across both depths. Chemically, soils were strongly acidic, with mean topsoil pH of 5.1 and subsoil pH of 4.9. Low inherent fertility was observed, characterized by low organic carbon (1.2% in topsoil), deficient available phosphorus (9.5 mg/kg), low exchangeable potassium (0.15 cmol/kg), and a very low cation exchange capacity (<6.1 cmol/kg). Analysis of variance (ANOVA) revealed statistically significant differences (p < 0.05) between topsoil and subsoil for all major properties, including increased clay content with depth. Based on these properties, soils were classified under the FCC system as SBe⁺-ac-nk, indicating sandy topsoil with low CEC, a subsoil with higher clay content, aluminum toxicity, and deficiencies in nitrogen and potassium. Recommendations include the application of organic manure to ameliorate acidity, integrated use of organic and inorganic fertilizers to improve nutrient levels and retention, and adoption of conservation practices like mulching. This research provides a foundation for sustainable soil fertility management in the region.

Abstract Male infertility is a growing global health issue, affected by environmental, nutritional, and occupational factors that reduce semen quality. This research examined how Brachystegia eurycoma seed intake impacts serum lipid profiles, blood parameters, and sperm fertility in male Wistar rats. Rats received 0 (control), 200, 400, or 800 mg/kg of seed extract daily for 14 days. Semen results showed dose-dependent effects: the 800 mg/kg group had the highest sperm motility (45%) and normal morphology (75%), while the 400 mg/kg group experienced lower motility (25%) and sperm count (25 million/ml). Lipid analysis revealed significant rises in total cholesterol (299 mg/dl) and triglycerides (442 mg/dl) at 800 mg/kg, along with the lowest HDL (33 mg/dL) and highest LDL (178 mg/dL). Conversely, the 400 mg/kg group had reduced TC (120 mg/dl) and TG (132.5 mg/dl). Blood tests indicated maximum PCV (22.5%) and Hb (112.03%) at 400 mg/kg, but the 800 mg/kg group showed moderate PCV (20.5%), Hb (102.26%), and increased WBC (117.46%). The rise in cholesterol and triglycerides at 800 mg/kg might support steroid production, while intermediate doses disturbed lipid balance and damaged sperm quality. Hematological results suggest that improvements in oxygen and red blood cell production alone couldn’t offset damage to lipid metabolism or testicular health. These findings show that B. eurycoma seeds have complex, dose-dependent impacts on male reproductive health, emphasizing the important relationship between lipid metabolism, blood health, and spermatogenesis.

The study focuses on the role of female child education in re-defining gender inequality in Nigeria. Education as the key enables the female child the opportunity to acquire knowledge and skills for development purposes. One of the objectives of the study is to uncover the root causes of inequality in education as it affects the development of girl child capability. Related concept on a girl child education and gender inequality are reviewed. The study is anchored on the sociology of inequality as postulated by Ashley Crossman. The methodology adopted for the study is survey research method using questionnaire and online interview as instrument for data collection. The population for the study is 5,459,000. The sample size is 400 according to Taro Yamane’s formula. The data gathered for the study is presented in tables, simple percentages and analyzed based on the sequence of the questionnaire. Findings from the study revealed that cases of inequality in education against girl child exist and the root cause is based on the socio-economic factors such as patriarchy, preference given to male children and traditional belief. Other findings in the aspect of challenges centre on poverty, poor living standard as well as inconsistent government policies and implementation. The study therefore recommends for affirmative action for effective realization of a girl child development on the bases of inclusiveness and representation, careers of their choices as well as safety in school environment.

Modelling of streamflow of Owan, Ikpoba and Ossisomo Rivers were carried out by least square regression method with the help of Microsoft Excel Software. The available streamflow data (stage and discharge) of Ikpoba, Owan and Ossiomo Rivers were calibrated from 1989 to 2000. The performance of calibration was measured by using measures of goodness of fit such as Coefficient of determination (R2) ranging between 0.9937 and 0.9991, Coefficient of correlation (R) ranging between 0.9918 and 0.9995, Nash-Sutcliffe model Efficiency (NSE) ranging between 0.969 and 0.9991 Standard error of estimate of discharge on stage (SQH) or Root Mean Square Error (RMSE) ranging between 0.30 and 2.59, and Mean Absolute Relative Error (MARE) ranging between 0.9962 and 1.000. The streamflow models developed in this research are very important as they will help in ensuring that future planning/management of water supply in Edo State, Nigeria are efficiently and scientifically made in order to have enough water to meet the needs of human, animals as well as natural systems.

Biting and parity status of black flies were evaluated between the transmission seasons (rainy and dry) after long-term Ivermectin treatments in Imo River Basin, Nigeria. Captured black flies were morphologically identified, dissected and assessed by standard protocol. Although more black flies were caught in the rainy season (54.3%) than dry season (45.3%), there was insignificant difference in the transmission parameters (P>0.05). Infection rate (0.2% versus 1.2%), parous rate (19.9% versus 22.4%), Infectivity rate (0.0% versus 0.0%), monthly biting rate (3,533.75 versus 3,095.5) bites/person/month, monthly parous biting rate (703.75 versus 771.5) bites and monthly transmission potential (0.0% versus 0.0%) were comparable for the seasons respectively. The data showed the existence of residual infection at the level of transmission likely to be insignificant to maintain parasite population.

The relationship between social capital resources and entrepreneurial success has been thoroughly researched; however, the significance of gender discrepancies in shaping the influence of internal and external social capital is largely unexplored. The goal of this study is to compare how gender orientation reflects the impact of social capital resources (internal and external) on entrepreneurial sustainability in Nigeria. A self-administered survey was used to collect data. Using the purposive approach, a scale was constructed and administered to a sample of male and female business ventures from three states in Nigeria's southeastern area. This study applied multigroup sampling and structural equation modeling. According to the findings, internal social capital resources have a significant influence on the business success of both genders of entrepreneurs. Conversely, social capital (external) resources have a direct and favorable influence on both male-owned and female-owned entrepreneurial enterprises' corporate performance. This study contributes to the body of knowledge by investigating the influence of social capital resources on the long-term success of male- and female-operated entrepreneurial ventures in Nigeria.

This study, employing remote sensing and Geographic Information System (GIS) techniques, was carried out using the categorical change detection technique to analyze land use and land cover (LULC) dynamics in Wales, United Kingdom, from the year 1992 to 2019 with a view to understanding the trend of urbanization in the area. Using data from the Global Land Cover 1992 to 2019 image service accessible via ArcGIS Pro 3.0 Living Atlas, with a spatial resolution of 300 meters, the study revealed that grassland, being the predominant land cover in the area, decreased in coverage from 73.98% in 1992 to 72.16% in 2019, cropland decreased from 17.91% to 17.48%, all categories of forest increased from 5.30% to 5.93%, water bodies decreased from 1% to 0.7%, while bare areas remained constant at 0.2% in both years. Results also revealed a significant expansion of urban areas, growing from 1.81% to 3.48% of the land area. The mean percentage change across all counties is approximately 97.29%, indicating substantial urban expansion, while the median percentage change is 68.88%. Counties in South Wales experienced substantial urbanization influenced by coastal proximity, while Western and Northern regions showed significant percentage changes in urban areas but had smaller land area expansions. This research provides insights into the evolving landscape of Wales vital for understanding trends in land use, environmental changes, and urban expansion over this period and contributes valuable insights for sustainable urban planning, environmental preservation, and possible ecological impacts within the study area.

Solid Electrolyte/Ion-Exchange Membrane was synthesized from sulfonated natural rubber (NR) for application in lithium-ion batteries. The separator was synthesized using chlorosulfuric acid as the sulfonating agent. The Scanning Electron Microscope/Energy Dispersive X-Ray (SEM-EDX) revealed that the membrane was highly porous and had high yarn-like arrangements; its water uptake (WU) was 16.6%, which demonstrated there is a robust attraction between the solid electrolyte/ion-exchange membrane and water molecules, having an ion exchange capacity (IEC) of 0.005632 mol/g and a degree of sulfonation (DS) of 8.468590%. The EDX mapping confirms that sulfonation occurred in the natural rubber with a substantial amount of sulfur and carbon. The porous and spongy structure throughout the surface area of the membrane indicates promising material for application in lithium-ion batteries.
