The present study investigates the neuroprotective effects of the sea urchin Paracentrotus lividus gonadal extract on rotenone-induced neurotoxicity in a Parkinson's disease (PD) rat model. Parkinson's disease, characterized by the progressive loss of dopaminergic neurons in the substantia nigra (SN), is exacerbated by oxidative stress and neuroinflammation. The study involved fifty Wistar rats divided into five groups: control, dimethyl sulfoxide (DMSO) control, Paracentrotus lividus gonadal extract-treated, rotenone-treated, and combined rotenone with Paracentrotus lividus gonadal extract-treated.

Interactions of VMAT2 with CDCrel-1 and Parkin in Methamphetamine Neurotoxicity.

Int J Mol Sci

December 2024

Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences, Wayne State University, 259 Mack Ave., Detroit, MI 48201, USA.

In recent years, methamphetamine (METH) misuse in the US has been rapidly increasing, and there is no FDA-approved pharmacotherapy for METH use disorder (MUD). In addition to being dependent on the drug, people with MUD develop a variety of neurological problems related to the toxicity of this drug. A variety of molecular mechanisms underlying METH neurotoxicity has been identified, including the dysfunction of the neuroprotective protein parkin.

Atrazine is an endocrine-disrupting herbicide, with exposure impacting adverse outcomes along multiple endocrine pathways. This study investigated the neuroendocrine system as the central target of atrazine toxicity, examining effects of early developmental exposures on neurohormones and genes associated with kisspeptin, hypothalamic, pituitary, and dopamine systems. Zebrafish were exposed to 0, 0.

Acute Paraoxon-Induced Neurotoxicity in a Mouse Survival Model: Oxidative Stress, Dopaminergic System Alterations and Memory Deficits.

Int J Mol Sci

November 2024

Department of Pharmacology, Toxicology and Therapeutic Chemistry, Pharmacology Section and Institute of Biomedicine (IBUB), Faculty of Pharmacy, University of Barcelona, 08028 Barcelona, Spain.

Article Synopsis
  • The study investigates the secondary neurotoxicity resulting from severe organophosphorus (OP) poisoning, specifically paraoxon (POX), and its impact on cognitive functions in surviving mice.
  • Mice were injected with POX followed by various treatments, resulting in high survival rates but significant neurological changes such as increased lipid peroxidation and alterations in neurotransmitter levels in key brain areas linked to memory.
  • Despite no signs of depression or anxiety, the study found long-term memory impairments in the mice, highlighting the model's usefulness for exploring the effects of OP exposure and strategies to combat associated cognitive deficits.

Adverse effects of diethyl phthalate and butyl benzyl phthalate on circadian rhythms and sleep patterns in zebrafish larvae.

Ecotoxicol Environ Saf

December 2024

Center for Predictive Model Research, Division of Advanced Predictive Research, Korea Institute of Toxicology, Daejeon, 34114, Korea; Human and Environmental Toxicology, University of Science and Technology, Daejeon 34113, South Korea. Electronic address:

The zebrafish, a diurnal vertebrate, is commonly used in circadian rhythm studies due to its genetic and neurological similarities to humans. Circadian rhythms, which regulate sleep, neurotransmitter, behavior, and physiological responses to environmental changes, can be disrupted by various environmental factors. Phthalic acid esters (PAEs) are pervasive endocrine disruptors that individuals are frequently exposed to in daily life.

Article Synopsis
  • Pathological cardiac hypertrophy significantly increases the risk of heart failure, and current treatments are not very effective, highlighting the need for new interventions.
  • This study found that FGF13 levels are elevated in hypertrophic heart tissues and are linked to key hypertrophy markers, indicating its role in the condition.
  • The research also identified miR-421 as a regulator that negatively affects FGF13, providing insight into a potential new therapeutic strategy for treating cardiac hypertrophy.

The effect of adrenalectomy on bleomycin-induced pulmonary fibrosis in mice.

Am J Physiol Lung Cell Mol Physiol

January 2025

Department of Internal Medicine, Section of Pulmonary, Critical Care, and Sleep Medicine, Yale School of Medicine, New Haven, Connecticut, United States.

Article Synopsis
  • Progressive lung fibrosis is a serious condition with limited treatments, and it is linked to hormones like adrenaline and aldosterone from the adrenal glands.
  • A study using mice found that removing the adrenal glands (adrenalectomy) did not change collagen buildup due to bleomycin but improved lung remodeling and reduced certain inflammatory cells.
  • These findings suggest that the adrenal glands play a role in lung fibrosis and that adrenalectomy might be protective, highlighting the need for further research to explore new treatment options.

Artificial intelligence application for identifying toxic plant species: A case of poisoning with Datura stramonium.

Toxicon

November 2024

Department of Emergency Medicine, Aksaray Training and Research Hospital, Aksaray, Turkey; Department of Emergency Medicine, Aksaray University School of Medicine, Aksaray, Turkey.

Article Synopsis
  • Managing plant poisonings in the emergency department is complicated, mainly due to the difficulty in identifying the specific toxic plant species involved, which is critical for determining the appropriate treatment.
  • A case of a 23-year-old male who experienced severe symptoms after consuming herbal tea led to the identification of Datura stramonium (jimson weed) using AI software, as timely access to botanical expertise was unavailable.
  • The case suggests that AI tools with visual recognition can aid healthcare providers in accurately identifying toxic plants, enhancing patient safety and treatment effectiveness.
