Food Contamination and Safety in Nigeria: A Systematic Synthesis of Heavy Metals, Microbial Pathogens, and Health Risk Metrics

open access: yesFood Safety and Health, EarlyView.
This is an infographic driver of food contaminants and health effects. ABSTRACT Food safety remains a critical challenge in Nigeria due to rapid urbanization and weak regulatory enforcement. This systematic review synthesizes empirical evidence from 2015 to 2025 to characterize food contaminant profiles and associated human health risks in Nigeria ...

Induction and Analysis of Anti-CD40-induced Colitis in Mice

open access: yesBio-Protocol, 2019
Colon inflammation or colitis affects more than 1 million people worldwide. Several pre-clinical models, including chemical-induced (i.e., DSS, TNBS) or pathogen-induced (i.e., Citrobacter rodentium) have been used to study mechanisms involved in the ...

Abnormal IgG galactosylation and arthritis in MRL‐Faslpr or MRL‐FasLgld mice are under the control of the MRL genetic background

open access: yesFEBS Letters, 2001
MRL mice bearing the lpr (Fas) or gld (Fas ligand) mutation, MRL‐Faslpr or MRL‐FasLgld , respectively, develop arthritis similar to rheumatoid arthritis, but C3H and C57BL/6 mice bearing such mutations do not. In MRL‐Faslpr mice, agalactosylated oligosaccharides in serum IgG increase significantly in comparison to MRL‐+/+ mice without arthritis.

Climate change effects on biomass and greenhouse gas emissions are ameliorated by nontoxic endophytes in southeastern USA transition zone tall fescue pastures

open access: yesGrassland Research, EarlyView.
Tall fescue produces more biomass and less carbon dioxide from the soil when it contains its beneficial fungal endophyte. Increased temperatures projected with climate change reduce fescue biomass, while altered rainfall frequency does not. Altering rainfall frequency and increasing temperatures can reduce carbon dioxide emissions from soil.

Disease Site‐Specific Outcomes in p16‐Positive Non‐Oropharyngeal Mucosal Head and Neck Cancer

open access: yesHead &Neck, EarlyView.
ABSTRACT Objectives To report disease‐free survival (DFS) in p16‐positive non‐oropharyngeal head‐and‐neck squamous‐cell carcinoma (HNSCC). Methods Curatively‐treated non‐oropharyngeal HNSCC (2009–2021) were reviewed. DFS was compared among p16‐positive, p16‐negative, and p16‐untested cases for the overall cohort and by disease site.

Recent Progress of Potentiating Immune Checkpoint Blockade with External Stimuli—an Industry Perspective

open access: yesAdvanced Science, 2020
The past decade has seen the materialization of immune checkpoint blockade as an emerging approach to cancer treatment. However, the overall response and patient survival are still modest. Various efforts to study the “cancer immunogram” have highlighted

Association between patient safety culture, adverse events, and essential practices during childbirth in six Brazilian maternity hospitals

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective This study examines whether hospitals with stronger patient safety culture more consistently follow essential birth practices and have fewer adverse outcomes for mothers and newborns and whether this evidence can guide maternity care priorities in patient safety policy.

A generalization of periodic autoregressive models for seasonal time series [PDF]

open access: yes, 2018
Many nonstationary time series exhibit changes in the trend and seasonality structure, that may be modeled by splitting the time axis into different regimes. We propose multi-regime models where, inside each regime, the trend is linear and seasonality is
