AI Article Synopsis
- Petroleum hydrocarbons, particularly polycyclic aromatic hydrocarbons (PAHs), are a significant pollution problem in the Niger Delta due to oil extraction activities.
- Water samples from the Ovia River showed PAH concentrations ranging from 0.1 to 1055.6 ng L(-1), and the African catfish (Heterobranchus bidorsalis) exhibited notable tissue changes detected by ATR-FTIR spectroscopy.
- The alterations in the catfish tissues are similar to changes caused by benzo[a]pyrene in human cells, raising health concerns for local communities that rely on this fish for nutrition, while also highlighting the effectiveness of infrared spectroscopy in environmental monitoring.
Article Abstract
Petroleum hydrocarbons including polycyclic aromatic hydrocarbons (PAHs) are a pollution issue in the Niger Delta region due to oil industry activities. PAHs were measured in the water column of the Ovia River with concentrations ranging from 0.1 to 1055.6 ng L(-1). Attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy detected alterations in tissues of the African catfish (Heterobranchus bidorsalis) from the region showed varying degrees of statistically significant (P<0.0001, P<0.001, P<0.05) changes to absorption band areas and shifts in centroid positions of peaks. Alteration patterns were similar to those induced by benzo[a]pyrene in MCF-7 cells. These findings have potential health implications for resident local communities as H. bidorsalis constitutes a key nutritional source. The study provides supporting evidence for the sensitivity of infrared spectroscopy in environmental studies and supports their potential application in biomonitoring.

The healing of bacterial biofilm-infected wounds is a complex process, and the construction of emerging therapeutic modalities that regulate the microenvironment to magnify therapeutic effects and reduce biotoxicity is still highly challenging. Herein, an engineered microneedle (MN) patch is reported to mediate the efficient delivery of black phosphorus nanosheets (BP NSs) and copper peroxide nanodots (CP NDs) for dual nanodynamic sterilization and methicillin-resistant staphylococcus aureus (MRSA)-infected wound healing. Results demonstrate that the system can eliminate biofilm, reduce cytotoxicity, promote angiogenesis and tissue regeneration by the multiple advantages of chemodynamic therapy (CDT), enhanced photodynamic therapy (PDT), and improved degradation process from BP NSs to phosphate for promoting cell proliferation.

Introduction: Research on the association between blood groups and cardiovascular diseases (CVDs) in Africa, including Algeria, is notably limited, with a primary focus on blood donors. This narrow scope hinders a comprehensive understanding of the genetic diversity of blood groups and their potential links to CVD risk within the African context. To bridge this knowledge gap, this study proposes to investigate the distribution of blood group genotypes and their association with CVD prevalence, aiming to enhance knowledge within the African context and contribute to global insights into the relationship between blood groups and CVD.

Access to diagnostic imaging is significantly limited in much of the world, and sub-Saharan Africa is no exception. Clinician-performed point-of-care ultrasound (POCUS) may provide increased access to diagnostic imaging for many patients in low-resource settings, but training in this modality is limited. We describe the development and implementation of a context-specific, multi-modal pilot POCUS curriculum involving hands-on instruction, in-person and online didactics, asynchronous online image review, and quantitative evaluation.

Introduction: Human tissue samples are essential for translational cancer research. However, less than 20% of current biobank and genomic samples were obtained from minority patients, which may lead to biased understanding of cancer biology. The objective of this study was to identify factors associated with patient enrollment in our institution's gastric cancer biobank.

Lung cancer is one of the most frequently diagnosed cancers in the US. African-American (AA) men are more likely to develop lung cancer with higher incidence and mortality rates than European-American (EA) men. Herein, we report high-confidence alternative splicing (AS) events from high-throughput, high-depth total RNA sequencing of lung tumors and non-tumor adjacent tissues (NATs) in two independent cohorts of patients with adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC).
