Dietary exposure to the plasticiser bisphenol A (BPA), an obesogenic and endocrine disruptor from plastic and epoxy resin industries, remains prevalent despite regulatory restriction and food safety efforts. BPA can be accumulated in humans and animals, potentially exerting differential health effects based on individual metabolic capacity. This pilot study examines the impact of direct ex vivo BPA exposure on the gut microbiota of obese and normal-weight children, using 16S rRNA amplicon sequencing and anaerobic culturing combined methods.

Post-Concussion Syndrome (PCS) represents a complex constellation of symptoms that persist following a concussion or mild traumatic brain injury (mTBI), with significant implications for patient care and outcomes. Despite its prevalence, diagnosing PCS presents considerable challenges due to the subjective nature of symptoms, the absence of specific diagnostic tests, and the overlap with other neurological and psychiatric conditions. This review explores the multifaceted diagnostic challenges associated with PCS, including the heterogeneity of symptom presentation, the limitations of current neuroimaging techniques, and the overlap of PCS symptoms with other disorders.

In solid-state nuclear magnetic resonance (ssNMR) spectroscopy, fast magic angle spinning (MAS) is a potent technique that efficiently reduces line broadening and makes it possible to probe structural details of biological systems in high resolution. However, its utilization in studying complex heterogeneous biomaterials such as bone in their native state has been limited. The present study has demonstrated the feasibility of acquiring two-dimensional (2D) H-H correlation spectra for native bone using multiple-quantum/single-quantum correlation experiments (MQ/SQ) at fast MAS (70 kHz).

The nitrogen mustard alkylating agent chlorambucil (CBL) is a critical component of chemotherapeutic regimens used in the treatment of chronic lymphocytic leukemia. The cancer cell-killing actions of CBL are limited by glutathione (GSH) conjugation, a process catalyzed by the GSH transferase hGSTA1-1 that triggers CBL efflux from cells. In the cancer cell microenvironment, intracellular GSH levels are elevated to counterbalance oxidative stress generated due to the high glycolytic demand.

Metabolomics is emerging as a significant approach to reflect the individual's response to pathophysiological conditions. Nuclear magnetic resonance (NMR) spectroscopy has evolved as a tool to identify metabolic dysregulations in critically ill patients afflicted with conditions like acute respiratory distress syndrome (ARDS), severe acute pancreatitis (SAP), acute kidney injury (AKI), and sepsis. The spectral data from the serum sample of the study and control group are recorded using an 800 MHz NMR spectrometer and processed using NMR processing and analysis tools.

TDP-43 regulates LC3ylation in neural tissue through ATG4B cryptic splicing inhibition.

Acta Neuropathol

September 2024

Metabolic Pathophysiology Research Group, Department of Experimental Medicine, University of Lleida (UdL), Lleida Biomedical Research Institute (IRBLleida), 25198, Lleida, Spain.

Article Synopsis
  • - Amyotrophic lateral sclerosis (ALS) is a severe motor neuron disease with about a three-year average survival time, primarily characterized by TDP-43 protein issues that affect gene stability and autophagy processes.
  • - Research on ALS mice revealed that reducing ATG4B worsens survival and autophagy, while an increase in LC3ylation was observed in both ALS patients and mouse models, suggesting a link between these processes.
  • - Antisense oligonucleotides (ASOs) targeting TDP-43 genes have been developed, showing potential for non-invasive treatments that can effectively distribute in the brain after administration.

Increased CXCL12, a potential CSF biomarker for differential diagnosis of amyotrophic lateral sclerosis.

Brain Commun

August 2024

Group of Neurological diseases and Neurogenetics-Bellvitge Biomedical Research Institute (IDIBELL), L'Hospitalet de Llobregat, Barcelona 08907, Spain.

Amyotrophic lateral sclerosis is a debilitating and lethal neurodegenerative disorder marked by the gradual deterioration of motor neurons. Diagnosing amyotrophic lateral sclerosis is challenging due to the lack of reliable diagnostic tools, with clinical assessment being the primary criterion. Recently, increased levels of neurofilament light chain in CSF have been considered a useful biomarker in disease, correlating with disease progression but not specific for diagnosis.
