Over the last few years, livestreaming e-commerce has shown rapid growth and has become an important form of e-commerce. However, the potential mechanisms of interpersonal interaction's influence on purchase intention in livestreaming e-commerce have yet to be fully investigated. Based on the SOR (Stimulus-Organism-Response) framework, this study reveals the association between interpersonal interaction (consumer-anchor interaction and consumer-consumer interaction), psychological distance, consumer purchase intention, and the positive role of brand identification and time pressure in this context of influential relationships.

Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis is among the most consistent neuroendocrine abnormalities in major depressive disorder (MDD). The peptide adrenocorticotropin hormone (ACTH) mediates HPA axis function during stress and is encoded by the proopiomelanocortin (POMC) gene polycistronically. After screening 39 POMC polymorphisms, we evaluated the association of polymorphisms with susceptibility to MDD in 145 MDD patients and 193 normal subjects; in patients, we also evaluated the response to treatment with antidepressants.

β-Arrestin 1 is known to be involved in the pathophysiology of major depressive disorder (MDD) and in the underlying mechanism of action of antidepressant therapies. After we screened 39 ARRB1 polymorphisms, we investigated the associations of seven ARRB1 single-nucleotide polymorphisms (SNPs) with the risk of MDD in 270 patients with MDD and 204 normal subjects, and with mirtazapine treatment response in patients with MDD. The genotype distributions of -132C>T and IVS1+85T>C showed significant deviations from Hardy-Weinberg equilibrium in patients with MDD but not in normal subjects.

Background/aims: The genetic variations in serotonin-related genes may be associated with antidepressant treatment response in major depressive disorder (MDD). The tryptophan hydroxylase-1 (TPH1) gene and serotonin 5A receptor (HTR5A) gene are known to be involved in serotonin biosynthesis and signal transduction, respectively. The purpose of this study was to investigate a possible interaction between the TPH1 gene and the HTR5A gene in the treatment outcome of escitalopram in MDD.

We report a case of pure red cell aplasia (PRCA) subsequent to an allogeneic bone marrow transplantation with a major ABO mismatch, which was resistant to the standard treatment options such as plasma exchange, erythropoietin and changes in the immunosuppressive treatment. Accordingly, two cycles of Rituximab therapy were administered without success. The patient had a chronic graft-vs.

We report the preparation of multilayer organic thin films prepared by sequential vapor-phase coupling of monomers. The reactions were carried out at room temperature and atmospheric pressure. Films prepared using up to six sequential coupling reactions are reported.

Article Synopsis
  • The study focuses on the electrochemical properties of gold (Au) and palladium (Pd) monolayer-protected clusters (MPCs) created using dendrimer templates.
  • Differential pulse voltammetry was employed to estimate the size of these MPCs, which aligned well with microscopic measurements and theoretical predictions.
  • Results indicated that the size estimation from electrochemical data was accurate, while transmission electron microscopy tended to overestimate the sizes of the smallest palladium nanoparticles due to resolution limitations.
