The slow-acting antirheumatic drugs (SAARDs) are being used in an increasing proportion of patients with rheumatoid arthritis (RA). The potential toxicity of each drug is well recognised. Many patients with RA will be on other medications and the potential for adverse drug interactions with SAARDs is not so well publicised. There have, over the years, been numerous reports of possible drug interactions with SAARDs but few of these are clinically relevant. It is, however, vitally important that the physician is aware of a number of potentially life-threatening interactions, particularly those associated with methotrexate. The SAARDs are a very useful group of drugs for the treatment of RA and, by being aware of their potential toxicity and drug interactions, hopefully they can be used safely and effectively.

The distribution of substitutional aluminum (Al) atoms in zeolites affects molecular adsorbate geometry, catalytic activity, and shape and size selectivity. Accurately determining Al positions has been challenging. We used synchrotron resonant soft x-ray diffraction (RSXRD) at multiple energies near the Al K-edge combined with molecular adsorption techniques to precisely locate "single Al" and "Al pairs" in a commercial H-ZSM-5 zeolite.

Objectives: Pancreatic cancer, a highly invasive and prognostically unfavorable malignant tumor, consistently exhibits resistance to conventional chemotherapy, leading to substantial side effects and diminished patient quality of life. This highlights the critical need for the discovery of novel, effective, and safe chemotherapy drugs. This study aimed to explore bioactive compounds, particularly natural products, as an alternative for JAK2 protein inhibitor in cancer treatment.

G protein-coupled receptors (GPCRs) represent the largest family of plasma membrane proteins targeted for therapeutic development. For decades, GPCRs were investigated as monomeric entities during analysis of their pharmacology or signaling and during drug development. However, a considerable body of evidence now indicates that GPCRs function as dimers or higher-order oligomers.

Although human genetics has substantial potential to illuminate novel disease pathways and facilitate drug development, identifying causal variants and deciphering their mechanisms remain challenging. We believe these challenges can be addressed, in part, by creatively repurposing the results of molecular trait genome-wide association studies (GWASs). In this review, we introduce techniques related to molecular GWASs and unconventionally apply them to understanding , a human coronary artery disease risk locus.

Introduction: Breast cancer resistance protein (BCRP) is an efflux membrane transporter that controls the pharmacokinetics of a large number of drugs. Its activity may change when taking some endo- and exogenous substances, thus making it a link in drug interactions.
Aim: The aim of the study was to develop a methodology for testing drugs for belonging to BCRP substrates and inhibitors in vitro.
