Article Abstract
Aim: Ischemia-reperfusion (IR) injury-induced renal failure is a major cause of death and morbidity. Unfortunately, there is currently no proven protective therapy. The aim of the study is to investigate the protective effect of D-carvone against the renal ischemia-reperfusion (RIR) injury.
Method: The study was conducted with 24 male Wistar-Albino rats. Rats were divided into three groups: Sham, RIR, and RIR + D-carvone (20 mg/kg) intraperitoneally daily for 15 days. ELISA was used to measure the levels of Neutrophil Gelatinase-Associated Lipocalin (NGAL), Ischemia-Modified Albumin (IMA), Tumor Necrosis Factor-alpha (TNF-α), interleukin-1beta (IL-1β), and IL-10. Aebi's spectrophotometric method was used to measure the levels of Catalase (CAT), Malondialdehyde (MDA), Glutathione (Reduced Form) (GSH), and Myeloperoxidase (MPO). Oxidative Stress Index (OSI) was computed, and Total Antioxidant Status (TAS) and Total Oxidant Status (TOS) levels were also assessed. Nuclear Factor kappa-light-chain-enhancer of activated B cells (NFκB), caspase-3, and Microtubule-associated protein 1 A/1B-light chain 3B (LC3B) were quantified using immunohistochemical and histological methods.
Results: TNF-α, IL-6, IL-1β, NGAL, MDA, MPO, TOS, OSI, and IMA levels decreased significantly in the treatment group, while IL-10, TAS, GSH, and CAT levels increased. LC3B, NFκB, and Caspase-3 levels, which increased with RIR damage, decreased significantly in the treatment group. Mild congestion and necrosis were observed in the kidney tissues in the treatment group compared to the RIR group.
Conclusion: D-carvone decreases oxidative stress and protects against kidney damage by having anti-inflammatory, anti-apoptotic, and autophagy inhibitory actions against IR damage. Based on the results, D-carvone may be a potential protective agent in therapeutic settings.

Autoimmune nodopathies: emerging insights and clinical implications.
Curr Opin Neurol
October 2025
Neuromuscular Diseases Unit, Department of Neurology, IR SANT PAU, Hospital de la Santa Creu i Sant Pau, CIBERER, Barcelona, Spain.
Purpose Of Review: Autoimmune nodopathies (AN) are a recognized distinct group of immune-mediated peripheral neuropathies with unique immunopathological features and therapeutic implications. This review synthesizes recent advances in their pathogenesis, diagnosis, and management, which have refined their clinical classification and informed targeted treatment strategies.
Recent Findings: AN are characterized by autoantibodies targeting surface proteins in the nodal-paranodal area (anti-contactin-1, anti-contactin-associated protein 1, anti-neurofascin-155, anti-pan-neurofascin), predominantly of IgG4 subclass.
Frozen potential: embryo research at the crossroads of ethics, regulation and scientific opportunity.

In an era of expanding reproductive possibilities, the human embryo has come to represent both immense potential and profound constraint. Advances in medically assisted reproduction (MAR) have led to the cryopreservation of hundreds of thousands of embryos each year, yet many remain unused and are ultimately discarded. Meanwhile, studies aimed at understanding infertility, early human development and preventing miscarriage continue to face significant barriers, with only a small fraction of embryos ever donated to research.

Background: Poor hand dexterity may increase the risk of functional disability; however, few studies have examined the relationship between hand dexterity and incident functional disability. The aim of this study was to prospectively investigate the dose-response association of hand dexterity with incident functional disability in community-dwelling older adults.
Methods: This study included 1,069 older adults aged ≥65 years in Kasama City, Japan.
Comparative outcomes of excision and active surveillance for cervical intraepithelial neoplasia 2 in women under 35: a single institutional retrospective study.

Department of Obstetrics and Gynecology, Seoul National University Hospital, Seoul, Korea.
Objective: This study aimed to compare the outcomes of excision (conization) and active surveillance in women under 35 years of age diagnosed with cervical intraepithelial neoplasia 2 (CIN 2) on disease regression to normal cervical cytology and the effectiveness of nonsurgical management.
Methods: This retrospective cohort study was conducted at OOO. Women under 35 diagnosed with CIN 2 were included and divided into two groups based on the management strategy: excisional treatment or active surveillance.
Prodromal Lewy Body Symptoms and α-Synuclein Seeding in Idiopathic Olfactory Dysfunction.

Department of Neurology, Danish Dementia Research Centre, Copenhagen University Hospital-Rigshospitalet, Copenhagen, Denmark.
Background: Early identification of pathological α-synuclein deposition (αSynD) may improve understanding of Lewy body disorder (LBD) progression and enable timely disease-modifying treatments.
Objectives: We investigated αSynD using a seed amplification assay and assessed prodromal LBD symptoms in individuals with idiopathic olfactory dysfunction (iOD).
Methods: In this cross-sectional, case-control study, we included iOD participants and normosmic healthy controls (HC) aged 55 to 75 years without diagnoses of dementia with Lewy bodies, Parkinson's disease (PD), or other major neurological disorders.
