Genomic and transmission dynamics of the 2024 Marburg Virus Outbreak in Rwanda.

The ongoing outbreak of Marburg virus disease (MVD) in Rwanda marks the third largest historically, though it has exhibited the lowest fatality rate. Genomic analysis of samples from 18 cases identified a lineage with limited internal diversity, closely related to a 2014 Ugandan case. Our findings suggest that the Rwandan lineage diverged decades ago from a common ancestor shared with diversity sampled from bats in Uganda.

Biofilm-Forming Antibiotic-Resistant Bacteria in Water From Distribution Systems: Occurrence and Public Health Implications.

Biofilm is a structurally-connected microbial community, covered by a self-produced polymeric matrix and adhered to biotic or abiotic surfaces. This study aimed to evaluate the occurrence of biofilm-producing antibiotic-resistant bacteria in water from distribution systems. Water samples were taken from 32 tanks across Ondo City and Akure metropolis, Nigeria.

Aerosol Assisted Chemical Vapour Deposition (AACVD) of Zinc dichalcogenoimidodiphosphinate Complexes for the Deposition of Zinc Selenide Thin Films.

Dichalcogenoimidodiphosphinate complexes of zinc [Zn{(EPPr)N}], [E=Se,Se; S,Se] were synthesized through metathetical reactions from the dichalcogenoimidodiphosphinate ligands [(EE'PPrNH)] (E, E'=Se, Se; S, Se). These complexes were characterized and used as single-source precursors through Aerosol-Assisted Chemical Vapour Deposition (AACVD) for the deposition of cubic zinc selenide (ZnSe) films on glass substrates. The deposition temperature occurred at 500 and 525 °C, while the flow rates of the carrier gas was 160 and 240 standard cubic centimetre (sccm).

Bioactive compounds from fermented leaf: Potent antibiotics against multidrug-resistant and .

Unlabelled: Antibiotic resistance microorganisms (ARMs), particularly gram-negative bacteria, pose a global health threat. The effects of fermentation on phytochemicals are numerous, and exploring this potential is the focus of drug development. The study investigated the role of fermentation in modifying leaf secondary metabolites as an effective antibiotic against .

Crisis-induced vibrational resonance in a phase-modulated periodic structure.

Double vibrational resonance is reported for a driven oscillator in a periodic structure of the Josephson junction type with high-frequency phase modulation. We identify two distinct phase modulation effects, namely, resonant induction and resonant amplification, leading to the appearance of a double resonance. We analyze these vibrational resonance phenomena theoretically and numerically, and we show that the origin of the induced resonance is traceable to a transition from periodicity to quasiperiodicity associated with an attractor-merging crisis.

Frequency of chloroquine-resistant haplotype of Plasmodium falciparum (CVIET) in Ibadan, Southwest Nigeria 17 years post-chloroquine withdrawal.

The replacement of chloroquine with artemisinin-based combination therapies (ACTs) for over a decade has had varying impacts on the ability of the malaria parasite to sustain its chloroquine resistance prowess in different malaria-endemic regions. We evaluated the frequency of Plasmodium falciparum chloroquine resistance transporter (PfCRT) mutations in Ibadan, Nigeria 17 years after the replacement of chloroquine with ACTs for malaria treatment. Fragments of PfCRT gene from genomic DNA of microscopically confirmed P.

Per- and polyfluoroalkyl substances contamination of drinking water sources in Africa: Pollution sources and possible treatment methods.

Despite the detection of poly- and perfluorinated alkyl substances (PFAS) in the water system in Africa, the effort towards mitigating PFAS in water in Africa needs to be better understood. Therefore, this review evaluated the contamination status and mitigation methods for handling PFAS-contaminated water systems in Africa. The findings revealed the presence of PFAS in wastewater treatment plant (WWTP) effluents, surface water and commercially available bottled and tap water in African countries.

Neuroinflammation and oxidative redox imbalance drive memory dysfunction in adolescent rats prenatally exposed to Datura Stramonium.

Although there have been reports indicating that Datura Stramonium (D. stramonium) may induce anticholinergic and neuropsychiatry effects, the compound is still being used for recreational and medicinal purposes while ingestion during pregnancy has been documented. Intriguingly, minimal studies have investigated the potential neurotoxic impact of D.

Emergency of per- and polyfluoroalkyl substances in drinking water: Status, regulation, and mitigation strategies in developing countries.

The detection of per- and polyfluoroalkyl substances (PFAS) in water presents a significant challenge for developing countries, requiring urgent attention. This review focuses on understanding the emergence of PFAS in drinking water, health concerns, and removal strategies for PFAS in water systems in developing countries. This review indicates the need for more studies to be conducted in many developing nations due to limited information on the environmental status and fate of PFAS.

The Role of Vitamin C on ATPases Activities in Monosodium Glutamate-Induced Oxidative Stress in Rat Striatum and Cerebellum.

Monosodium glutamate (MSG) is a silent excitotoxin used as a flavour enhancer but exerts serious health hazards to consumers. MSG plays a role in neuronal function as the dominant excitatory neurotransmitter. It is transferred into the blood and ultimately increases brain glutamate levels, causing functional disruptions notably via oxidative stress.

Hepatitis Delta Virus Surveillance Practice among Clinicians in Nigeria: A Cross-Sectional Survey.

Background: The near total absence of routine Hepatitis Delta Virus (HDV) screening in many countries in sub-Saharan Africa is a major challenge to understanding the burden of HDV in the region.

Aim: To evaluate Hepatitis Delta Virus screening practices and associated factors among clinicians in Nigeria.

Methods: A cross-sectional study was conducted in June-July 2022, in which a self-administered questionnaire that inquired about HDV awareness, screening practices, and treatment options was shared electronically with consenting clinicians practicing in Nigeria.

Performance of Adult's Death and Burial Among Ilaje People of Southwest Nigeria.

The meaning ascribed to death differs from one society to the other. This study adopts the descriptive method in unraveling the ritual of burial practices among the Ilaje people of Nigeria's Niger delta. Based on linguistic similarities, Ilaje people are part of the Yoruba ethnic group of Nigeria's Southwest area.

Innovative techniques for combating a common enemy forever chemicals: A comprehensive approach to mitigating per- and polyfluoroalkyl substances (PFAS) contamination.

The pervasive presence of per and polyfluoroalkyl substances (PFAS), commonly referred to as "forever chemicals," in water systems poses a significant threat to both the environment and public health. PFAS are persistent organic pollutants that are incredibly resistant to degradation and have a tendency to accumulate in the environment, resulting in long-term contamination issues. This comprehensive review delves into the primary impacts of PFAS on both the environment and human health while also delving into advanced techniques aimed at addressing these concerns.

Development and validation of the Global Adolescent and Child Physical Activity Questionnaire (GAC-PAQ) in 14 countries: study protocol.

Introduction: Global surveillance of physical activity (PA) of children and adolescents with questionnaires is limited by the use of instruments developed in high-income countries (HICs) lacking sociocultural adaptation, especially in low- and middle-income countries (LMICs); under-representation of some PA domains; and omission of active play, an important source of PA. Addressing these limitations would help improve international comparisons, and facilitate the cross-fertilisation of ideas to promote PA. We aim to develop and assess the reliability and validity of the app-based Global Adolescent and Child Physical Activity Questionnaire (GAC-PAQ) among 8-17 years old in 14 LMICs and HICs representing all continents; and generate the 'first available data' on active play in most participating countries.
