Therapeutic resistance in cancer is responsible for numerous cancer deaths in clinical practice. While target mutations are well recognized as the basis of genetic resistance to targeted therapy, nontarget mutation resistance (or nongenetic resistance) remains poorly characterized. Despite its complex and unintegrated mechanisms in the literature, nongenetic resistance is considered from our perspective to be a collective response of innate or acquired resistant subpopulations in heterogeneous tumors to therapy.

Purpose Of Review: Effective vaccines to prevent sexually transmitted Chlamydia trachomatis (Ct) infection have eluded researchers for decades. However, recent studies of a promising vaccine in human trials, and emerging understanding of the complexity of the natural immune response to infection have provided hope for the eventual approval of a vaccine. This review highlights recent progress toward developing effective vaccines for Ct.

The discovery of RET mutations in Multiple Endocrine Neoplasia 2A (MEN2A) in 1993 ignited a revolution in our understanding of this versatile receptor. Since then, RET's influence has expanded to encompass diverse organs, including the pituitary gland. This review explores the multifaceted role of RET in somatotrophs, focusing on two opposing pathways: proliferation versus differentiation and apoptosis.

Aims: This study focuses on the synthesis and characterization of novel sitagliptin derivatives, aiming to develop potent, orally active anti-diabetic agents with minimal side effects for the management of type 2 diabetes mellitus. Copper (II) (SCu1-SCu9) and zinc (II) (SZn1-SZn9) metal complexes of sitagliptin-based derivatives were synthesized via a template reaction.
Material & Method: The synthesized complexes were comprehensively characterized using elemental analysis, FTIR, UV-Vis, 1 h NMR, and 13C NMR spectroscopy.

Sepsis is a global health challenge, characterized by a dysregulated immune response, leading to organ dysfunction and death. Despite advances in medical care, sepsis continues to claim a significant toll on human lives, with mortality rates from 10-25% for sepsis and 30-50% for septic shock, making it a leading cause of death worldwide. Current diagnostic methods rely on clinical signs, laboratory parameters, or microbial cultures and suffer from delays and inaccuracies.
