The occurrence of microstate C was positively correlated with attractiveness judgement. Source location revealed that microstate C during repeated exposure activated the middle frontal gyrus. These results indicate repeated exposure affects the emotional brain system when processing middle attractive faces. Our findings suggest the cognitive and affective brain systems play an important role in the changes of facial attractiveness judgement. BACKGROUND Ring annuloplasty (Ring) and suture bicuspidization annuloplasty (Suture-bicuspidization) are two utilized techniques for tricuspid valve repair. With the emergence of transcatheter tricuspid valve repair technologies that mimic these conventional surgical techniques, we compared their mid-term outcomes and longitudinal echocardiographic profiles. METHODS From 2002 to 2016, 650 patients underwent TV repair (324 Ring and 326 Suture-bicuspidization) for primary or functional tricuspid regurgitation (TR). Concomitant aortic valve, mitral valve or CABG procedures were included but tricuspid valve replacement, concomitant aortic procedures, heart transplantation or ventricular assist device placement procedures were excluded. Tricuspid valve event-free survival was estimated using Kaplan-Meier competing risk analysis. Freedom from TR recurrence (defined as at least moderate TR) and freedom from tricuspid valve reoperation were also assessed. RESULTS There were no statistical differences in terms of age, gender, and most baseline comorbidities (P>0.05). In-hospital outcomes also did not significantly differ between the two groups (P>0.05). However, Suture-bicuspidization was associated with significantly lower tricuspid valve event-free survival, and freedom from TR recurrence and tricuspid valve reoperation compared to Ring at 1, 5 and 8 years (all P less then 0.05). selleck chemical After adjusting for significant confounders, Suture-bicuspidization continued to be associated with significantly decreased tricuspid valve event-free survival (HR 2.13, 95% CI 1.3 - 3.4). CONCLUSIONS The superiority of Ring over Suture-bicuspidization annuloplasty for tricuspid valve repair appeared to be evident in terms of event-free survival, and freedom from tricuspid valve insufficiency and reoperation. These findings raise concern in the context of emerging transcatheter technologies which mimic the bicuspidization technique. INTRODUCTION The prognostic significance of temporal changes in resting heart rate in young adults for premature heart failure and cardiovascular disease is unclear. We investigated the association between temporal changes in resting heart rate in young adults and early adult risk factors, subsequent cardiac function, and the risk of heart failure and cardiovascular by middle age. MATERIALS AND METHODS We examined 4343 Coronary Artery Risk Development in Young Adults (CARDIA) study participants (mean (SD) age was 29.9 (3.6) years at the CARDIA Year-5 exam [1990-1991], 49% of participants were men, and 45% were African-American). Adjusted linear regression models were used to assess the association between temporal changes in resting heart rate, early life cardiovascular disease risk factors, and mid-life cardiac function. Cox proportional hazard regression models were used to relate temporal changes in resting heart rate to heart failure and cardiovascular disease. Outcomes were followed up until August 31, 2 in resting heart rate and early adult risk factors and subsequent cardiac dysfunction. The deteriorating effects of heat stress abrogate the therapeutic implications of human Wharton's jelly derived mesenchymal stem cells (hWJMSCs) transplanted in burn wounds. Topically applied green tea extract comprising epigallocatechin-3-gallate (EGCG) is known to repair burn wounds. Here, we investigated the protective role of EGCG priming of hWJMSCs against heat-induced stress in vitro along with the involved underlying mechanism. EGCG ameliorated heat-induced injuries as demonstrated by significantly improved cell morphology, viability, triggered cell migration and enhanced expression of heat shock proteins. In addition, decreased lactate dehydrogenase release and reduced percentage of senescent and apoptotic cells were observed. EGCG priming alleviated the detrimental effects of thermal stress in hWJMSCs as observed by significant down-regulation in expression of BCL2 associated X (BAX), interleukin 6 (IL6), and interleukin 1 beta (IL1β) genes, while proliferating cell nuclear antigen (PCNA), BCL2 like 1 (BCL2L1), vascular endothelial growth factor (VEGF), transforming growth factor beta 1 (TGFβ1), hepatocyte growth factor (HGF) and interleukin 4 (IL4) genes were up-regulated. Accompanying gene expression data, EGCG primed cells exposed to heat stress also exhibited remarkably increased secretion of VEGF, HGF, epidermal growth factor (EGF), stromal-derived factor 1 (SDF1) proteins while the reduced release of IL-6, and tumor necrosis factor-alpha (TNF-α) proteins. Further, synergistic activation of extracellular-signal-regulated kinase (ERK) and protein kinase B (PKB/AKT) proteins was observed. These findings suggest that EGCG priming might enhance the therapeutic efficacy of hWJMSCs in the burnt tissue through regulation of ERK and AKT signaling pathways, and improved cellular responses. Pituitary adenylate cyclase-activating polypeptide (PACAP) acts on adrenal medullary (AM) cells as a neurotransmitter of the sympathetic preganglionic nerve. In guinea-pig AM cells, PACAP induces little catecholamine secretion, but enhances secretion evoked by stimulants, whereas in other animals, such as mouse, PACAP itself induces depolarization and/or catecholamine secretion. The present studies aim to explore the physiological implication of these species differences in PACAP actions, the ion channel mechanism for PACAP-induced depolarization, and the mechanism for facilitation of muscarinic receptor-mediated cation currents in mouse and guinea-pig AM cells. The perforated patch clamp technique was used to record the whole-cell current in isolated AM cells. The amplitudes of 3 nM PACAP-induced inward currents were significantly larger in mouse AM cells than guinea-pig, whereas 1 μM muscarine-induced currents were larger in guinea-pig AM cells than mouse. Exposure to PACAP consistently resulted in enhancement of muscarine-induced currents in guinea-pig AM cells and facilitation of cell membrane insertion of heteromeric TRPC1-TRPC4 channels in response to muscarine in PC12 cells.
