(1) Introduction: Toll-like receptors (TLRs) are key in immune response by recognizing pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). In gastric cancer (GC), TLR2, TLR3, TLR4, and TLR9 are crucial for modulating immune response and tumor progression. (2) Objective: This study aimed to assess the percentage of dendritic cells and monocytes expressing TLR2, TLR3, TLR4, and TLR9, along with the concentration of their soluble forms in the serum of GC patients compared to healthy volunteers.

Background: Eliminating hepatitis C virus (HCV) infections is a goal set by the World Health Organization. This has become possible with the introduction of highly effective and safe direct-acting antivirals (DAA) but limitations remain due to undiagnosed HCV infections and loss of patients from the cascade of care at various stages, including those lost to follow-up (LTFU) before the assessment of the effectiveness of the therapy. The aim of our study was to determine the extent of this loss and to establish the characteristics of patients experiencing it.

Cyclophosphamide (CPAm) is a widely used chemotherapeutic agent that exhibits potent anti-cancer properties but is often associated with debilitating side effects. Despite its efficacy, the management of CPAm-induced toxicities remains a significant clinical challenge. There has been growing interest in exploring complementary and alternative therapies to mitigate these adverse effects in recent years, and this may be a chance for the earthworm-derived preparation, Venetin-1.

Comparative study of the photosynthetic efficiency and leaf structure of four Cotoneaster species.

Sci Rep

October 2024

Department of Plant Physiology and Biophysics, Institute of Biological Sciences, Maria Curie- Skłodowska University, Akademicka 19, 20-033, Lublin, Poland.

Plants belonging to the genus Cotoneaster can be valuable sources of phytochemicals with potential therapeutic properties. The natural habitats of most of these species are situated in Asia, Africa and southern Europe. Introducing them into other climatic conditions could expose them to abiotic and biotic stresses, affecting their bioactive properties.

Patients with high-grade ovarian cancer have a poor prognosis, thus effective treatment remains an unmet medical issue of high importance. Moreover, finding the reason for resistance to cisplatin is a crucial task for the improvement of anti-cancer drugs. In this study, we showed for the first time a chemical difference in a serum collected from platinum-resistance and platinum-sensitive women suffering from ovarian cancer using Fourier Transform InfraRed (FTIR) spectroscopy followed by a data analysis by Principal Component Analysis (PCA), Hierarchical Component Analysis (HCA) and 4 different machine learning algorithms.

The optimization of sample preparation on zebrafish larvae in vibrational spectroscopy imaging.

Spectrochim Acta A Mol Biomol Spectrosc

February 2025

Independent Unit of Spectroscopy and Chemical Imaging, Medical University of Lublin, Chodzki 4a Street, 20-093 Lublin, Poland. Electronic address:

The zebrafish (Danio rerio) larvae are widely used in biomedical, pharmaceutical, and ecotoxicological studies. Their transparency and translational potential make them particularly valuable for fluorescence imaging. In addition to fluorescence imaging, microspectroscopy, which combines vibrational spectroscopy: Raman or Fourier transform infrared (FT-IR) with microscopy, allows the collection of spatially resolved, label-free information.

Department of Experimental and Clinical Pharmacology, Centre for Preclinical Research and Technology (CePT), Medical University of Warsaw, Warsaw, Poland.

Article Synopsis
  • - The study analyzed the time it takes for drugs registered by the EMA from 2014 to 2019 to receive reimbursement recommendations in Poland and 11 other countries.
  • - Results showed that Poland had a significantly longer time from drug registration to recommendation compared to other countries, although many countries are trending towards faster recommendations between 2014 and 2019.
  • - The findings indicate potential improvements in the processes of health authorities and data providers, with Poland experiencing a yearly decrease in the time for reimbursement recommendations despite starting from a longer baseline.

Intrafamilial Disease Heterogeneity in Primary Hyperoxaluria Type 1.

Kidney Int Rep

October 2024

Institute of Human Genetics, Center for Molecular Medicine Cologne, University Hospital of Cologne, Cologne, Germany.

Introduction: Primary hyperoxaluria type 1 (PH1) is known for its variable clinical course, even within families. However, the extent of this heterogeneity has not been well-studied. We aimed to analyze intrafamilial clinical heterogeneity and disease course among siblings in a large cohort of familial PH1 cases.

Anal Biochem

January 2025

Department of Biochemistry and Molecular Biology, Medical University of Lublin, Lublin, 20-093, Poland; Institute of Nuclear Physics, PAS, 31342, Krakow, Poland. Electronic address:

This study employed Fourier transform infrared (FTIR) spectroscopy to determine the chemical composition of brain tissues and the changes induced by irisin at doses of 50 mg and 100 mg. Brain tissues were collected from control rats and those administered with irisin, and key vibrational peaks were analyzed. In the 50 mg irisin group, all described vibrations decreased compared to control tissues, while the 100 mg group showed a decrease only in lipid vibrations.

Department of Medicine, Division of Nephrology, Columbia University, College of Physicians & Surgeons, New York, NY, USA.

Article Synopsis
  • IgA vasculitis (IgAV) is a pediatric disease characterized by skin and systemic symptoms, and researchers conducted comprehensive studies involving genome, transcriptome, and proteome analyses on a large cohort of IgAV patients and controls to better understand the disease mechanisms.* -
  • Significant associations were found with specific genetic risk factors, including two novel non-HLA loci linked to IgA receptor functioning, which may contribute to disease development through altered immune responses.* -
  • Systems biology approaches helped identify key regulatory networks and master regulators in myeloid cells, along with 21 genetic loci that overlap with IgA nephropathy, suggesting shared pathways in these related conditions.*

MP0250 is a designed ankyrin repeat protein that specifically inhibits both vascular endothelial growth factor A (VEGF-A) and hepatocyte growth factor (HGF), aiming at potentiating cancer therapy by disrupting the tumour microenvironment. Encouraging results from a phase 1 trial of MP0250 in patients with solid tumours prompted further investigation in multiple myeloma (MM) as both MP0250 targets are reported to be drivers of MM pathogenesis. In this open-label, single-arm phase 1b/2 study (NCT03136653) in patients with proteasome inhibitor- and/or immunomodulatory drug-relapsed or refractory MM, MP0250 was administered every 3 weeks with standard bortezomib/dexamethasone regimen.

Debates concerning the reliability and validity of operationalized criteria and diagnostic tools have surrounded the issue of schizophrenia diagnosis and clinical decision-making related to the disorder. The notion of the praecox feeling (PF) has played a prominent role in the discussions as an example of the possibility of a rapid and potentially valid diagnosis based solely on "intuition" or a peculiar emotional experience or impression arising in a physician during an interaction with a patient with schizophrenia. In this paper, we argue that PF is enabled by the (phenomenologically understood) intercorporeal dimension of the clinical encounter.
