Significant gaps were identified in the availability of equipment, essential drugs and perioperative routines.The human multidrug transporter ABCG2 is required for physiological detoxification and mediates anticancer drug resistance. Here, we identify pivotal residues in the first intracellular loop (ICL1), constituting an intrinsic part of the transmission interface. The architecture includes a triple helical bundle formed by the hot spot helix of the nucleotide-binding domain, the elbow helix, and ICL1. We show here that the highly conserved ICL1 residues G462, Y463, and Y464 are essential for the proper cross talk of the closed nucleotide-binding domain dimer with the transmembrane domains. Hence, ICL1 acts as a molecular spring, triggering the conformational switch of ABCG2 before substrate extrusion. These data suggest that the ABCG2 transmission interface may offer therapeutic options for the treatment of drug-resistant malignancies. This study sought to investigate the relationship between allodynia, psychological variables, and disability among individuals with migraine. A growing body of research views migraine as a condition of stress-related physiological dysregulation. Cutaneous allodynia is one manifestation of this dysregulation and affects a majority of individuals with migraine, though it is typically discussed in the context of headache pathophysiology. Stress, like allodynia, is implicated in the development of central sensitization and migraine progression. However, the contributions of stress and related psychological factors in allodynia and resulting disability remain largely unknown. A cross-sectional study at a Southern U.S. university queried young adults with migraine regarding headache symptoms, disability, allodynia symptom frequency, and psychological variables using validated measures. Relations among allodynia and psychological variables of relevance were examined, inclu
