A series of hybrid molecules 6a-6d-13a-13d combining pyrazolo[3,4-]pyrimidine or aminopurine frameworks with an oxindole moiety were designed as multitarget anticancer agents. Several compounds, especially 8b and 12a-12d, showed potent antiproliferative effects against three human cancer cell lines: A498 (kidney carcinoma), HepG-2 (hepatocellular carcinoma), and MDA-MB-231 (breast adenocarcinoma). Compounds 6b, 7b, 8b, and 12a-12c exhibited remarkable CDK6 inhibition (pIC of up to 7.

Background: The relationship between the second (2D) and fourth finger (4D) of the hand (2D:4D) is considered to be a proxy indicator of prenatal- testosterone (PT) and estrogen (PE) exposure in the first trimester of pregnancy. A lower 2D:4D indicates relatively higher PT exposure and vice versa. The 2D:4D is generally higher in women than in men.

The Apemen Faces Database is a novel and versatile stimulus set designed for research in behavioral biology, evolutionary psychology, and related fields. The dataset comprises 620 photorealistic, artificially generated facial images of 31 generalized hominin models, available in multiple ocular coloration variants (31 hominins x 20 color variants). Each of the 31 facial portraits is paired with geometric morphometric data and norming information that includes perceptual ratings of six constructs (Threat, Sociability, Trustworthiness, Health, Age, and Masculinity).

Background: Obstructive sleep apnoea (OSA) is a prevalent sleep disorder that contributes to serious cardiovascular comorbidities. While the mechanical aspects of OSA are well-studied, its neurobiological underpinnings remain underexplored. In this study, we investigated the role of dopamine and its genetic modulators in OSA pathophysiology.

Since their initial synthesis by Hawthorne in the 1960s, inorganic metallacarboranes - most notably cobalt bis(dicarbollide), [CoSAN], have been considered chemically inert and harmless to eukaryotic cells. This reputation for inertness has supported their use in a wide range of biomedical applications, including as a boron source for boron neutron capture therapy, antifungal and Gram-positive antibacterial agents, and superchaotropic membrane carriers for impermeable biologically important molecules. In this study, we report a surprising twist: newly synthesized, iodinated and charge-compensated [CoSAN] derivatives with boron-nitrogen (-B-N-) bond show promising anticancer activity.

Pharmacogenetics of graft-versus-host disease: a path to personalized medicine.

Pharmacogenomics

August 2025

Laboratory of Clinical Immunogenetics and Pharmacogenetics, Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, Wroclaw, Poland.

Graft-versus-host disease (GvHD) remains a significant complication of allogeneic hematopoietic stem cell transplantation (HSCT), contributing to increased morbidity and mortality. Thus, continuous development of novel prophylactic and therapeutic approaches is crucial for GvHD prevention and management. With the current development of personalized medicine and a more patient-oriented approach, pharmacogenetics has the potential to become a critical factor in optimizing the prophylaxis and treatment of GvHD.

A number of studies showed that vitamin D reveals antiproliferative activity against cancer cells, however some lung cancer cells are more sensitive than others. Secondly, there are some controversies around the role of SIRT1 in lung cancer: on one hand it was demonstrated that SIRT1 contributed to the development of lung cancer, on the other hand SIRT1 was showed to be downregulated in lung cancer. Third, it was demonstrated that VDR is posttranslationally modified via deacetylation by SIRT1 what potentiated VDR activity.

Introduction: Catheter-associated urinary tract infections (CAUTIs) are among the most prevalent hospital-acquired infections, posing a serious clinical and economic burden, particularly in the context of rising antibiotic resistance. Biofilm formation on indwelling catheters by multidrug-resistant uropathogens further complicates treatment and prevention, underscoring the urgent need for alternative, non-antibiotic solutions.

Areas Covered: This article explores the potential of bacteriophage- and enzybiotic-coated urinary catheters as an innovative strategy to prevent recurrent bacterial infections.

Colorectal cancer (CRC) patients undergoing chemotherapy often experience anemia, oxidative stress, and immune suppression, significantly impacting their quality of life and treatment outcomes. Normobaric oxygen (NBO) therapy, which delivers oxygen at atmospheric pressure with an elevated oxygen concentration, has shown the potential to enhance erythropoiesis, reduce oxidative stress, and modulate immune function. However, its efficacy in CRC patients remains underexplored.

Chronic lymphocytic leukemia (CLL) is a prevalent hematologic malignancy that predominantly affects elderly individuals, posing significant clinical challenges due to patient comorbidities and inherent resistance to conventional chemotherapy. The emergence of targeted therapies combining venetoclax, a selective inhibitor of the anti-apoptotic protein BCL-2, with anti-CD20 monoclonal antibodies has dramatically transformed the treatment landscape. This retrospective observational study analyzed the differential impacts of first-line venetoclax-obinutuzumab (VenO) and second-line venetoclax-rituximab (VenR) on immunoglobulin G (IgG) levels and absolute neutrophil count (ANC) in CLL patients.

: Gingipains produced by have been shown to be directly related to periodontal tissue degradation and are significant molecular targets in therapy of periodontitis. Blocking the activity of these enzymes should reduce survival of this pathogen and mitigate the effects of inflammation in periodontitis. Therefore, gingipains inhibitors and specific antibodies could be recommended in the treatment of periodontitis.
