Nigeria, being a tropical nation, characterized by favorable climatic conditions, may display high chances of feed contaminations due to aflatoxigenic with the consequences of health risks associated with the consumption of dairy products. A cross-sectional study was conducted to examine the risks of occurrence and distribution of aflatoxigenic () and aflatoxin B1 (AFB1) contamination levels based on the European Union (EU) and United States Food and Drug Administration (USFDA) set limits. Feeds (n = 144) were collected from selected conventional and traditional dairy herds; prepared and analyzed using immuno-affinity column (IAC) and high performance liquid chromatography (HPLC) respectively. Forty eight (55.8%) isolates were identified as of the isolated Aspergilli (n = 86). Of this proportion, 12 (25.0%) were aflatoxigenic strains. An outrageous number of the tested feeds (86.8%, n = 144) were positive for AFB1 contamination. Detectable AFB1 concentrations ranged between (0.5 and 24.8) μgKg and were distributed variously according to many factors of distribution. Eighty three (66.4%, n = 125) of the AFB1 contaminated feed samples showed AFB1 concentrations between 5 and ≥20 μgKg. All-inclusive policies are key to reducing the health risks posed to the consumers of dairy products.

Diversity patterns and knowledge gaps of Atlantic Forest epiphyllous bryophytes: a highly neglected group.
Ann Bot

Laboratório de Ecologia e Biogeografia de Plantas, Departamento de Biodiversidade, Setor Palotina, Universidade Federal do Paraná, Rua Pioneiro, 2153, Jardim Dallas, CEP 85950 000, Palotina, Paraná, Brazil.
Background: Epiphyllous bryophytes are a group of plants with complex adaptations to colonize the leaves of vascular plants and are considered one of the most specialized and sensitive groups to environmental changes. Despite their specificity and ecological importance, these plants represent a largely neglected group in relation to scientific research and ecological data. This lack of information directly affects our understanding of biodiversity patterns and compromises the conservation of this group in threatened ecosystems.

The strong solid-liquid interaction leads to the complicated occurrence characteristics of shale oil. However, the solid-liquid interface interaction and its controls of the occurrence state of shale oil are poorly understood on the molecular scale. In this work, the adsorption behavior and occurrence state of shale oil in pores of organic/inorganic matter under reservoir conditions were investigated by using grand canonical Monte Carlo (GCMC) and molecular dynamics (MD) simulations.

Background: The Coronavirus Disease (COVID-19) has had a significant impact on healthcare organizations, leading to a reduction in screening. The pandemic period has caused important psychological repercussions in the most fragile patients.
Objectives: This study aimed to assess the levels of depression, anxiety, peri-traumatic stress, and physical symptoms in patients undergoing colposcopy during the COVID-19 pandemic and to compare these data with the post-pandemic period.

Descriptive analysis of interpreter service mode costs & usage in Northwestern Wisconsin pre and peri COVID-19.
BMC Health Serv Res
January 2025
Mayo Clinic Health System Northwest Wisconsin, Eau Claire, Wisconsin, USA.
Background: Interpreter service mode (in person, audio, or video) can impact patient experiences and engagement in the healthcare system, but clinics must balance quality with costs and volume to deliver services. Videoconferencing and telephone services provide lower cost options, effective where on site interpreters are scarce, or patients with limited English proficiency (LEP) and/or interpreters are unable to visit healthcare centers. The COVID 19 pandemic generated these conditions in Northwest Wisconsin (NWWI).
