Psychological resilience refers to the ability that individuals can positively adapt and respond to stress and adversity and is important for mental health and happiness. Previous studies have found that resilience is associated with the brain activity of regions within the cognitive-emotional system. However, there was little study examined the functional connectivity among these regions underlying psychological resilience. The present study used resting-state seed-based functional connectivity to explore the neural basis of psychological resilience and its association with positive affect in a big healthy sample. Results showed that resilience is associated with functional connectivity between regions involved in emotional flexibility, coping ability, and inhibitory control. Specifically, resilience is positively correlated with the strength of the left insula and right parahippocampus connectivity, which is involved in the self-evaluation and self-awareness. Resilience is also positively correlated with the strength of the left orbitofrontal gyrus(OFC) and left inferior frontal gyrus(IFG) connectivity, which is associated with the flexible use of emotional resources and flexible control in processing affective information. These results suggest that high-resilient individuals may exhibit flexible emotional responses and flexible inhibitory control. Additionally, resilience is negatively correlated with the strength of left OFC and right precuneus connectivity, which indicates that whether it is possible to bounce back from aversive events is important for resilience. Crucially, the strength of left OFC-IFG connectivity mediated the effect of positive affect on resilience, supporting the opinion that positive affect facilitates resilience by broadening one’s attention and promoting flexible thinking and coping abilities. In summary, these findings extend previous studies revealing the functional connectivity basis of psychological resilience and highlighting the l

This paper reveals the variations of S concentration among the leaf surface and other organs of variousplant species, and presents the distribution natures of S storage in the evergreen broad-leaved forest vege-tation in Hangzhou on the basis of the tested data concerning plant S contents. The result was that theS concentrations on the tree leaf surfaces varied with the testing time and plant species. The range of Scontents in various organs of a plant was 2.086- 4.245 S g kg￣(-1), varying with plant species in this *** S content in the leaves was the highest, followed by that in the branches, trunks and roots, which showedthat there was an apical dominance of S distribution. The total amount of S storage in the vegetation wasas large as 349.97 S kg ha￣(-1). The S distribution in this vegetation had two characteristics as follows: 1)for the vegetation layers, arbor layer > renewal layer > herb layer > shrub layer; and 2) for the verticaldistribution per unit height (m), root stratum (0 - 0.20 m of soil depth)> stratum nearby the ground surface(0 - 0.5m) > canopy (4.0- 9.5m) > trunk stratum (2.0- 4.0m).

Pancreatic ductal adenocarcinoma (PDAC) is an extremely malignant disease, which has an extremely low survival rate of <9% in the United States. As a new hallmark of cancer, metabolism reprogramming exerts crucial impacts on PDAC development and progression. Notably, arginine metabolism is altered in PDAC cells and participates in vital signaling pathways. In addition, arginine and its metabolites including polyamine, creatine, agmatine, and nitric oxide regulate the proliferation, growth, autophagy, apoptosis, and metastasis of cancer cells. Due to the loss of argininosuccinate synthetase 1 (ASS1) expression, the key enzyme in arginine biosynthesis, arginine deprivation is regarded as a potential strategy for PDAC therapy. However, drug resistance develops during arginine depletion treatment, along with the re-expression of ASS1, metabolic dysfunction, and the appearance of anti-drug antibody. Additionally, arginase 1 exerts crucial roles in myeloid-derived suppressor cells, indicating its potential targeting by cancer immunotherapy. In this review, we introduce arginine metabolism and its impacts on PDAC cells. Also, we discuss the role of arginine metabolism in arginine deprivation therapy and immunotherapy for cancer.

地域气候、生活习性等不同因素造就了汉民族右衽、少数民族左衽的主要服饰特征。左右衽背后是一直以来的“华夷之辨”的正统论观念,历代也默认遵循着汉人右衽、少数民族左衽的认同规则。蒙元时期绘画作品开始出现汉人形象左右衽并存的现象,集中体现在同一经典母题画的衣襟改动。蒙元绘画中产生人物左右衽变化现象的原因主要有三:宋与辽、金对峙时民间服饰交流的前期铺垫;蒙元大一统环境加速服饰文化融合;蒙元绘画机制重立及迎合性献画风气。其本质是蒙元时期“华夷之辨”观念从“胡化”“汉化”到“涵化”的嬗变过程。
