Determination of the mutations' status in the KRAS and NRAS genes is a necessary requirement in the treatment of patients with colorectal cancer (CRC). Patients with certain mutations in the KRAS and NRAS genes are resistant to anti-EGFR drug therapy and have a lower median survival rate than those with WT (wild type) genotypes, that indicates a negative prognosis in the case when mutations are present. Currently, there are no registered targeted drugs for carriers of the KRAS and NRAS genes mutations, however, preparations based on small molecules are under way. The gold standard for detecting mutations in the KRAS and NRAS genes is the analysis of the biopsy material in paraffin blocks. However, this method has significant limitations that can be circumvented by the analysis of circulating tumor DNA — a promising new method in the diagnosis of colorectal cancer

Создание методик диагностики на основе анализа движений глаз является особенно актуальным для оценки когнитивных функций у детей, которые не могут дать речевой или моторный ответ в силу своего возраста или из-за нарушений развития. Для таких детей использование объективных методов оценки когнитивных функций на основе айтрекинга может стать полезным диагностическим инструментом, дополняющим традиционные поведенческие опросники и ...

Активное развитие метода видеоокулографии, т. е. регистрации движений глаз, создает возможности для создания новых подходов для развития когнитивных функций и обучения. Методики, основанные на видеоокулографии, могут быть полезны не только для детей с серьезными нарушениями моторных функций, но и детей с нарушениями развития когнитивных функций, прежде всего внимания, так как контроль движений глаз тесно связан ...

Inhibition of the PD-1/PD-L1 axis has become a clinical standard across multiple malignancies, yet durable benefit remains restricted to selected settings, and many biologically rational combinations fail to maintain clinical benefit in late-phase evaluation. This structured, registry-derived narrative review, supported by expert-guided interpretation, was designed to identify the most clinically meaningful development directions among strategies ...

Background Cardiac fibrosis represents a significant health burden, with endothelial dysfunction and damaged
perivascular microenvironment increasingly recognized as key contributors to fibrotic remodeling. The urokinase
plasminogen activator receptor (uPAR), a critical component of the urokinase system, plays a pivotal role in vascular
remodeling and fibrosis. While prior evidence indicates that uPAR deficiency leads to microvascular dysfunction and
perivascular fibrosis, ...

Pediatric tumors such as neuroblastoma are characterized by a genome-wide ‘transcriptional burden’, surmising the involvement of multiple alterations of gene expression. Search for master regulators of transcription whose inactivation is lethal for tumor cells identified the non-POU domain-containing octamer-binding protein (NONO), a member of the Drosophila Behavior/Human Splicing family known for the ability to form ...

Copper–organic compounds are being investigated as antitumor candidates. Besides their efficacy as cytotoxic agents alone, the oxidative potential of electrochemical Cu2+-to-Cu1+ transition emerges as an attractive approach for elimination of tumor cells otherwise resistant to chemotherapy. To minimize side effects of the potent oxidative burst upon Cu(II) reduction, the metal cations should be delivered to the ...

A novel trend in anticancer therapy is based on the combination of cytotoxic and metabolic drugs. Bach1 is a transcription factor activating glycolysis and increasing proliferation and metastatic potential in cancer cells. The cytotoxic effect was evaluated for a combination of rotenone, an inhibitor of mitochondrial respiration, and two different inhibitors of Bach1 transcription factor ...

Recently, evidence indicating that microplastics (MPs) have a hazardous effect on human health is accumulating. The potential of MPs having a role in carcinogenesis was suggested. Therefore, the aim of this study was to evaluate MPs’ effect on colitis-associated colorectal cancer (CAC) development. The AOM/DSS-induced CAC model was reproduced in two groups of adult male ...

In this work, we comprehensively investigated the influence of Indium doping on the structure, magnetic and functional properties of strontium M-type hexaferrites SrFe12-xInxO19 nanoparticles (where x = 1.7, 1.8, 2.0). Colloidally stable SrFe12-xInxO19 nanoparticles (∼10 nm) were synthesized using a combination of the citrate method and high-energy ball milling. We demonstrate that doping reduces both the specific saturation magnetization and, ...

Understanding patterns of interhemispheric asymmetry is crucial for monitoring neuroplastic changes during post-stroke motor rehabilitation. However, conventional laterality indices often pose computational challenges when applied to functional near-infrared spectroscopy (fNIRS) data due to the bidirectional hemodynamic responses. In this study, we analyze fNIRS recordings from 15 post-stroke patients undergoing motor imagery brain-computer interface training across ...

T-cell engagers represent a transformative approach to cancer immunotherapy leveraging bispecific and multispecific antibody constructs to redirect T-cell cytotoxicity toward malignant cells. These molecules bridge T cells and tumor cells by simultaneously binding CD3 on T cells and tumor-associated antigens on cancer cells, thereby enabling precise immune targeting even in immunologically “cold” tumors. Recent advancements ...

Обоснование. Активаторы STING с направленной доставкой в опухолевые узлы обладают высоким потенциалом в иммунотерапии рака, особенно в формате иммуноконъюгатов. Известные соединения, такие как MSA-2, не обладают достаточной активностью для их использования в качестве активной составляющей иммуноконъюгата, поэтому требуется разработка новых, более активных соединений.
Цель. Изучение биологической активности нового соединения SAD-2 и оценка его перспективности с целью ...

ABSTRACT Modern oncology needs to develop and implement antineoplastic agents that provide sustained remission without serious side effects. Immunotherapy and targeted therapy agents that activate innate immunity may address this issue. The stimulator of interferon genes (STING), an intracellular protein, mediates the synthesis of type I interferons, which have antiviral, antitumor, and antiproliferative properties. The ...
