Abstract: Introduction: In order to restore injured organs or tissues, platelet rich plasma (PRP) has been employed as a treatment approach. Both endometrial and follicular growth was improved by platelet-rich plasma (PRP). According to studies, ovarian reserve was enhanced by infusing the ovary with platelet-rich plasma (PRP). Aim of study: To assess the impact of intraovarian infusion of platelet-rich plasma (PRP) in women with diminished ovarian reserve or premature ovarian insufficiency. Patients and methods: This prospective observational study was done at gala teaching hospital in the period between September 2024 and December 2025 where 20 women were diagnosed as poor responders and underwent intra ovarian PRP infusion. Results: The results of the study demonstrated statistically insignificant difference before and after PRP infusion in all ovarian reserve parameters regarding the mean AFC (2.75 ± 0.85 before & 3.15 ± 0.74 after), mean seum AMH (0.36 ± 0.19 ng/ml before & 0.4 ± 0.23ng/ml), mean serum FSH (11.9±1.29 miu/ml before & 11.39±1.09 miu /ml after) and mean number of oocytes (1.5 ± 1before & 1.95 ± 1.27after). Conclusion: Intra ovarian PRP infusion in poor responders didn’t significantly improve ovarian reserve parameters (AFC, serumAMH, serumFSH,) or the number of oocytes.

Abstract: Mycobacterium tuberculosis causes tuberculosis (TB), primarily affecting the lungs and remaining a significant threat globally. HIV infection accelerates TB progression. Coinfection of TB with hepatitis B virus (HBV) can worsen treatment outcomes, potentially leading to failure. Though TB is treatable, complications from hepatitis can occur, causing liver damage in some cases. This study aims to determine the prevalence and co-infection rate of tuberculosis and hepatitis B as well as its correlation with viral load among HIV patients receiving antiretroviral therapy. Two hundred (200) HIV-infected individuals receiving antiretroviral therapy (ART) at the Rivers State University Teaching Hospital (RSUTH), were enrolled and underwent screening for HBV surface antigens and tuberculosis using rapid diagnostic tests (RDTs). The HIV viral load was determined through Reverse Transcription-polymerase chain reaction (RT-PCR). Questionnaires were administered to gather demographic information and assess risk factors related to HBV and tuberculosis among the participants. The results indicated an overall prevalence of 3.0% for HBV, and 2.5% for TB and no co-infection was observed between tuberculosis and Hepatitis B. A high prevalence of 1.0% for HBV and 4.1% for TB was recorded among individuals aged 49-56 and 41-48, respectively. Among HBV cases, high prevalence rates were observed among males at 3.0%, singles at 4.2%, illiterates at 7.7%, and those with a viral load below 20 copies/ml at 3.6%. Conversely, for TB, higher prevalence rates were found among females 2.9%, married individuals (4.4%), those with primary education 8.7%, and 9.1% for participants with viral load exceeding 1000 copies/ml. However, there was no statistical association between the demographic variables and HBV and TB infection (p > 0.05). Conclusively, an overall prevalence of 2.5% and 3.0% was observed in tuberculosis and hepatitis B, respectively, in the studied population. There was no co-infection between tuberculosis and hepatitis B. Statistical analysis did not find significant associations between variables and infection rates. There is a need to carry out routine screening for the hepatitis B virus and TB among HIV-infected individuals for proper disease management and increased treatment success

Abstract. This study assesses the impact of hydro-climatic factors on the formation, transformation, and dynamics of landscapes in the Southern Fergana region. Particular attention is paid to long-term changes in air temperature, precipitation, humidity, and hydrological conditions, as well as their influence on natural and anthropogenic landscapes. Based on meteorological and hydrological data analysis, the research identifies recent trends in climate warming, changes in precipitation regimes, and increasing variability of water resources. The results indicate that rising temperatures and altered moisture conditions significantly affect soil properties, vegetation cover, and land use systems. These processes contribute to landscape degradation, increased aridity, and changes in ecosystem stability. The findings highlight the necessity of integrated landscape management and adaptive strategies to mitigate the negative impacts of hydro-climatic changes and to ensure sustainable development in the Southern Fergana region.

Abstract: This article examines the role of natural geographic factors in the formation of cultural and historical recreational tourism sites in the Tashkent region. The study analyzes the influence of relief, climate, water resources, and landscape diversity on the development and spatial distribution of tourism and recreational objects. The Tashkent region is characterized by diverse natural conditions, including mountainous and foothill landscapes, river valleys, and favorable climatic features, which create significant opportunities for tourism development. Many cultural and historical sites in the region have been formed and developed in close connection with natural geographic conditions. The research is based on geographical analysis, comparative methods, and the study of natural and tourism resources of the region. The results show that natural geographic factors play an important role in shaping the location and development of cultural and historical recreational tourism sites. In particular, mountainous landscapes, river systems, and favorable climatic conditions contribute to the formation of attractive tourism destinations. The findings highlight the importance of rational use and conservation of natural geographic resources to enhance the tourism potential of the Tashkent region.

ABSTRACT: This study investigates the design and assessment of an automated solar-powered borehole for the Jalingo community. The system offers an intelligent method for monitoring water levels, presenting an efficient and cost-effective solution for water observation in local areas. It comprises a solar panel, a controller, a water level sensor, a submersible pump, and a borehole. The system monitors the water level in a tank and automatically activates or deactivates the pump based on the water level. Designed with a microcontroller and various components, including solar panels, sensors, and relays, the prototype was evaluated for its performance and accuracy. Results indicated that the system could effectively monitor and regulate the water level in the tank. Furthermore, a cost analysis revealed that the system is economical and feasible for construction in rural communities.

ABSTRACT: The idea behind establishing correctional institution in all parts of the world including Nigeria is to provide rehabilitation and correctional facilities for those who have violated the rules and regulation of their society. Unfortunately, the time spent in this institution does not seem to successfully rehabilitate most inmates in Nigeria, due to some challenges and poorly adopted strategies. Following the increasing evidence of differentials in the prison treatment of male and female offenders, especially in the underdeveloped countries, this study sets out to investigate the extent of such gender differences in Nigeria. Purposely, the study aims to analyze   whether male and female inmates perceive their correctional facilities and experiences differently, and whether there is any correlation between such perception and their readjustment. Results show that most of the male and female inmates do not have any significant difference in their perception about the treatment and that there was a negative relationship between males’ and females’ attitude toward imprisonment. However, it is recommended that prison officials and policy makers should employ gender-neutral practices that promote equal opportunities for both male and female offenders.
