Computational Study of Chalcogenide-Based Perovskite Solar Cell Using SCAPS-1D Numerical Simulator.

Perovskite solar cells (PSCs) are regarded as extremely efficient and have significant potential for upcoming photovoltaic technologies due to their excellent optoelectronic properties. However, a few obstacles, which include the instability and high costs of production of lead-based PSCs, hinder their commercialization. In this study, the performance of a solar cell with a configuration of FTO/CdS/BaZrS/HTL/Ir was optimized by varying the thickness of the perovskite layer, the hole transport layer, the temperature, the electron transport layer (ETL)'s defect density, the absorber defect density, the energy band, and the work function for back contact.

This study aimed to examine factors associated with HPV vaccination among young adults and preferences for HPV vaccine information and promotion.

Extraction, Characterization, and Antioxidant Activity of Pectin from Lemon Peels.

Pectin is a natural polymer that is found in the cell walls of higher plants. This study presents a comprehensive analysis of pectin extracted from lemon in two different geographic regions (Peddie and Fort Beaufort) in two consecutive years (2023 and 2024) named PP 2023, PP 2024, FBP 2023, and FBP 2024. The dried lemon peels were ground into a powder, sifted to obtain particles of 500 μm, and then subjected to pectin extraction using a conventional method involving mixing lemon peel powder with distilled water, adjusting the pH level to 2.

Prevalence and determinants of moderate-to-severe anaemia in the third trimester of pregnancy: a multicenter cross-sectional study in Lagos, Nigeria.

The high burden of anaemia during pregnancy underscores the urgent need to gain a comprehensive understanding of the factors contributing to its widespread occurrence. Our study assessed the prevalence and the trends of moderate-to-severe anaemia (MSA) in late pregnancy (28 to 36 weeks) and then investigated the key determinants driving this prevalence among women in Lagos, Nigeria. We conducted a secondary data analysis involving 1216 women enrolled in the Predict-PPH study between January and March 2023.

Long-Term Ovarian Function Assessment After Haematopoietic Stem Cell Transplantation in Female Sickle Cell Anaemia Survivors.

Methods: We conducted a retrospective cohort study of female survivors who had hydroxyurea therapy and those who underwent post-HSCT follow-up for SCA at a teaching hospital in Lagos, Nigeria, between January 2019 and December 2022.

Views of the Pharmacists' Role in HPV Vaccinations: A Qualitative Study in Tennessee.

Unlabelled: The Human Papillomavirus (HPV) is a frequently occurring sexually transmitted infection in adults and is associated with various cancers that can affect both males and females. Recently, the Advisory Committee on Immunization Practices (ACIP) expanded its recommendations for the HPV vaccine to include patients aged 27-45 years with shared clinical decision-making. A commonly reported obstacle to receiving the HPV vaccine among adults is a lack of healthcare provider recommendations.

Wastes from Part of the Eastern Cape Province in South Africa: Medicinal, Sustainable Agricultural, and Bio-Resource Potential.

The fruits of are often purchased for their vitamin C-rich juice, while the fruit peel and the tree leaves are discarded as wastes. This study obtained the chemical profiles of the essential oils (EOs) of wastes (the peel and leaves), evaluated their medicinal value as antioxidants, their potential for sustainable use in agriculture as an insecticide for post-harvest preservation of grains, and their potential as a bioresource in livestock feed formulations. The EOs were isolated from leaves and peel using a hydro-distillation method on a Clevenger apparatus.

Incidence and Antepartum Risk Factors of Severe Postpartum Haemorrhage in Anaemic Pregnant Women in Lagos, Nigeria: A Secondary Cohort Analysis.

Background: The magnitude and risk factors for postpartum haemorrhage (PPH) have been extensively investigated, although little is currently known about the incidence and predictors of severe PPH, specifically among women affected by prenatal anaemia in Nigeria.

Objectives: The study determined the incidence and antepartum risk factors of severe PPH in anaemic pregnant women in five health institutions in Lagos, Southwest Nigeria.

Methods: A secondary analysis was performed using the data of pregnant women with anaemia from the "" study that was conducted between January and June 2023.

Coverage and determinants of infant postnatal care in Nigeria: A population-based cross-sectional study.

Importance: In 2019, Nigeria had the largest number of under-5 child deaths globally and many of these deaths occurred within the first week of life. The World Health Organization recommends infant postnatal care (PNC) attendance to support newborn survival; however, utilization of PNC is known to be low in many contexts.

Objective: This study examined coverage and individual-level determinants of infant PNC attendance in Nigeria.

How resilient are farmers in Africa to climate shocks? A case study of Nigerian farmers.

Agriculture in sub-Saharan Africa remains highly vulnerable to climate related shocks, since most production relies on rainfall. It is important to accurately measure the resilience of farmers and farming communities to weather variabilities, for both government policy and farmer management responses. This paper develops a Resilience Index Framework, which is further used to assess the resilience of farmers to climate shocks in Nigeria.

Therapeutic Potential of Pectin and Its Derivatives in Chronic Diseases.

Non-communicable diseases (NCDs) are described as a collection of chronic diseases that do not typically develop from an acute infection, have long-term health effects, and frequently require ongoing care and therapy. These diseases include heart disease, stroke, cancer, chronic lung disease, neurological diseases, osteoporosis, mental health disorders, etc. Known synthetic drugs for the treatment or prevention of NCDs become increasingly dangerous over time and pose high risks due to side effects such as hallucination, heart attack, liver failure, etc.

Perception and predictors of spousal involvement in antenatal care by women attending immunization clinic at babcock university teaching hospital, Ogun State, Nigeria.

Background: The level of spousal involvement in antenatal care (ANC) is not what it should be. This is a concern because a number of preventable maternal and neonatal mortality or morbidity can be attributed to a lack of interest or participation in ANC by their spouses, which usually result in a delay in seeking healthcare and/or delay in reaching a healthcare facility.

Aim: To assess the degree of spousal involvement in ANC among women accessing care at the Immunization Clinic in Babcock University Teaching Hospital (BUTH), Ogun State, Nigeria.

Pancreatic lymphoepithelial cyst with concurrent HIV infection: A case report and review of the literature.

Pancreatic lymphoepithelial cysts are rare, benign, non-neoplastic unilocular or multilocular cystic lesions. These circumscribed pancreatic lesions are filled with keratinous material grossly and exhibit distinct microscopic features. Pancreatic lymphoepithelial cysts are like the more common lymphoepithelial cysts of the parotid glands, which have been associated with the diffuse infiltrative lymphocytosis syndrome often seen in patients with HIV infection.
