NRF2 Modulators of Plant Origin and Their Ability to Overcome Multidrug Resistance in Cancers.

Cancer is one of the most common causes of death in the world. Despite the fact that there are many types of therapies available, cancer treatment remains a major challenge. The main reason for the ineffectiveness of chemotherapy is the acquisition of multidrug resistance (MDR) by cancer cells.

Preparation and Biochemical Activity of Copper-Coated Cellulose Nonwoven Fabric via Magnetron Sputtering and Alginate-Calcium Ion Complexation.

Alginate-based materials have gained significant recognition in the medical industry due to their favorable biochemical properties. As a continuation of our previous studies, we have introduced a new composite consisting of cellulose nonwoven fabric charged with a metallic copper core (CNW-Cu) covered with a calcium alginate (ALGCa) layer. The preparation process for these materials involved three main steps: coating the cellulose nonwoven fabric with copper via magnetron sputtering (CNW → CNW-Cu), subsequent deposition with sodium alginate (CNW-Cu → CNW-Cu/ALGNa), followed by cross-linking the alginate chains with calcium ions (CNW-Cu/ALGNa → CNW-Cu/ALGCa).

Potential of NRF2 Inhibitors-Retinoic Acid, K67, and ML-385-In Overcoming Doxorubicin Resistance in Promyelocytic Leukemia Cells.

Drug resistance is one of the major obstacles to the clinical use of doxorubicin, an extensively used chemotherapeutic drug to treat various cancers, including leukemia. Inhibition of the nuclear factor erythroid 2-related factor 2 (NRF2) seems a promising strategy to reverse chemoresistance in cancer cells. NRF2 is a transcription factor that regulates both antioxidant defense and drug detoxification mechanisms.

Blood Coagulation Activities and Influence on DNA Condition of Alginate-Calcium Composites Prepared by Freeze-Drying Technique.

The aim of this research was to synthesize and characterize alginate-calcium composites using a freeze-drying method, with a focus on their potential applications in biomedicine. This study specifically explored the biochemical properties of these composites, emphasizing their role in blood coagulation and their capacity to interact with DNA. Additionally, the research aimed to assess how the cross-linking process influences the structural and chemical characteristics of the composites.

The obese population's views on the symptoms and risks of chronic venous insufficiency - 2 (OBVIOUS-2) cross-sectional survey.

Introduction: Individuals with high body mass index (BMI) are more likely to have symptomatic LLVD than age matched populations with normal BMI. National priorities in venous disease set by the James Lind Alliance focus on improving access to healthcare and patient education. The aims of this study are to determine patient knowledge and potential burden of LLVD in a population of patients attending a UK, regional weight management service.
