Optimized protocol for culturing menstrual blood-derived MSCs for combination with oncolytic adenoviruses in cancer treatment.

Oncolytic viruses (OVs) are a promising therapeutic approach for cancer, although their systemic administration faces significant challenges. Mesenchymal stem cells have emerged as potential carriers to overcome these obstacles due to their tumor-tropic properties. This study investigates the use of menstrual blood-derived mesenchymal stem cells (MenSCs) as carriers for OVs in cancer therapy, focusing on enhancing their efficacy through different culture conditions.

Hand acceleration time (HAT) as a diagnostic tool in the assessment of haemodialysis access-induced distal ischaemia (HAIDI): study protocol for a prospective cohort study in the Barcelona south metropolitan area.

Introduction: Chronic hand ischaemia may affect some haemodialysis patients with an arteriovenous fistula (AVF) or graft (AVG), a condition known as haemodialysis access-induced distal ischaemia (HAIDI). Duplex ultrasonography (DUS) can provide comprehensive insights into anatomical and perfusion properties, and measuring the hand acceleration time (HAT) has been demonstrated to be sensitive within the framework of chronic upper limb ischaemia.

Methods And Analysis: This single-centre, prospective cohort study will involve adult end-stage renal disease (ESRD) patients requiring either AVF or AVG for haemodialysis.

Epsilon Toxin from Induces the Generation of Extracellular Vesicles in HeLa Cells Overexpressing Myelin and Lymphocyte Protein.

Epsilon toxin (ETX) from is a pore-forming toxin (PFT) that crosses the blood-brain barrier and binds to myelin structures. In in vitro assays, ETX causes oligodendrocyte impairment, subsequently leading to demyelination. In fact, ETX has been associated with triggering multiple sclerosis.

Detection of germline CNVs from gene panel data: benchmarking the state of the art.

Germline copy number variants (CNVs) play a significant role in hereditary diseases. However, the accurate detection of CNVs from targeted next-generation sequencing (NGS) gene panel data remains a challenging task. Several tools for calling CNVs within this context have been published to date, but the available benchmarks suffer from limitations, including testing on simulated data, testing on small datasets, and testing a small subset of published tools.

Clinical, Histological, and HPV-Related Factors Associated to Diffuse Presentation of Exophytic Nasal Papillomas.

: Sinonasal exophytic papillomas (SNEP) are benign tumours arising from nasal mucosa. Human papillomavirus (HPV) infection seems to be related to the aetiology of a fraction of SNEP cases. SNEP presentation can be focal (FSNEP) or diffuse (DSNEP), but factors related to focal or diffuse presentation have not yet been well ascertained.

Exploring the Chemopreventive Effect of Medication on Gene Expression Linked to Colorectal Cancer: An Observational and Mendelian Randomization Analysis in Healthy Colon Mucosa.

Gene expression appears altered in apparently normal tissue surrounding tumor tissue. The observed biological alterations in the tumor microenvironment play a crucial role in cancer development and are named the cancer field effect (FE). A robust set of overexpressed FE genes in tissue surrounding colorectal cancer (CRC) tumor were identified in previous studies.

Prognostic Impact of Statins in Heart Failure with Preserved Ejection Fraction.

Heart failure (HF) with preserved ejection fraction (pEF) has lacked effective treatments for reducing mortality. However, previous studies have found an association between statin use and decreased mortality in patients with HFpEF. The aim of this study was to analyse whether statin therapy is associated with a reduction in mortality in these patients and whether the effect differs according to the presence or absence of ischaemic heart disease (IHD).

Lemur tail kinase 3 serves as a predictor of patient outcomes and a target for the treatment of ovarian cancer.

Lemur tail kinase 3 (LMTK3) belongs to a family of tyrosine kinases that are known to correlate with tumor grade and patient survival in some cancers. Here, we validated LMTK3 as a specific target and a prognostic biomarker in ovarian cancer (OC). In samples from 204 stage I-II OC patients, immunohistochemical studies revealed a higher cytoplasmic-to-nuclear staining intensity of LMTK3, which correlated with worse overall survival ( < 0.

Optimizing ctDNA: An Updated Review of a Promising Clinical Tool for the Management of Uveal Melanoma.

Uveal melanoma (UM) is the most common primary malignant intraocular tumor in adults. Distant metastasis is common, affecting around 50% of patients. Prognostic accuracy relies on molecular characterization of tumor tissue.

A combination of Δ-tetrahydrocannabinol and cannabidiol modulates glutamate dynamics in the hippocampus of an animal model of Alzheimer's disease.

A combination of Δ-tetrahydrocannabinol (Δ-THC) and cannabidiol (CBD) at non-psychoactive doses was previously demonstrated to reduce cognitive decline in APP/PS1 mice, an animal model of Alzheimer's disease (AD). However, the neurobiological substrates underlying these therapeutic properties of Δ-THC and CBD are not fully understood. Considering that dysregulation of glutamatergic activity contributes to cognitive impairment in AD, the present study evaluates the hypothesis that the combination of these two natural cannabinoids might reverse the alterations in glutamate dynamics within the hippocampus of this animal model of AD.

Heterogeneous IL-9 Production by Circulating Skin-Tropic and Extracutaneous Memory T Cells in Atopic Dermatitis Patients.

Interleukin (IL)-9 is present in atopic dermatitis (AD) lesions and is considered to be mainly produced by skin-homing T cells expressing the cutaneous lymphocyte-associated antigen (CLA). However, its induction by AD-associated triggers remains unexplored. Circulating skin-tropic CLA and extracutaneous/systemic CLA memory T cells cocultured with autologous lesional epidermal cells from AD patients were activated with house dust mite (HDM) and staphylococcal enterotoxin B (SEB).

Review of Advancements in Managing Cardiogenic Shock: From Emergency Care Protocols to Long-Term Therapeutic Strategies.

Cardiogenic shock (CS) is a complex multifactorial clinical syndrome of end-organ hypoperfusion that could be associated with multisystem organ failure, presenting a diverse range of causes and symptoms. Despite improving survival in recent years due to new advancements, CS still carries a high risk of severe morbidity and mortality. Recent research has focused on improving early detection and understanding of CS through standardized team approaches, detailed hemodynamic assessment, and selective use of temporary mechanical circulatory support devices, leading to better patient outcomes.
