SCOPE: The induction of brown-like adipocytes in white adipose tissue (WAT) is a potential therapeutic target for the treatment of obesity and metabolic disorders via the ability of these cells to release excess energy as heat in association with uncoupling protein 1. Some experimental trials suggest that curcumin (a yellow pigment from turmeric) has a suppressive effect on the accumulation of body fat. However, there is little evidence to show that curcumin induces the formation of brown-like adipocytes and the molecular mechanisms involved remain elusive...

BACKGROUND: Bipolar disorder (BD) has been associated with dysfunctional resting-state brain functioning. However, it is still not known whether the aberrant functioning occurs and predict cognitive functioning before illness onset. AIMS: We examined the resting-state regional and network dysfunctioning, and their correlates with neurocognitive performance, in the high-risk (HR) and ultra-high-risk (UHR) stages of bipolar disorder. METHODS: Using amplitude of low-frequency fluctuations (ALFF), region homogeneity (ReHo) and hypothesis-driven region-of-interest (ROI)-based connectivity, we examined resting-state fMRI data of 8- to 25-year-old healthy offspring (HR, n = 28) and offspring with subthreshold syndromes (UHR, n = 22) of a BD parent, and age-matched healthy controls without any personal or family psychopathology (HC, n = 46)...

BACKGROUND AND AIM: Hepatitis C virus (HCV)-related cirrhosis, one of the most common etiologies of liver cirrhosis in the Western world, is a risk factor for hepatocellular carcinoma. To confirm and improve current effectiveness of screening and prognosis of patients with established cirrhosis, a credible, simple plasma biomarker is needed. Hepatic stellate cell activation, a pivotal event in cirrhosis development, results in increased secretion of extracellular matrix proteins, including tenascin-C (TnC)...

Hyperopic refractive error is detected by retinal neurons, which generate GO signals through a direct emmetropization signaling cascade: retinal pigment epithelium (RPE) into choroid and then into sclera, thereby increasing axial elongation. To examine signaling early in this cascade, we measured gene expression in the retina and RPE after short exposure to hyperopia produced by minus-lens wear. Gene expression in each tissue was compared with gene expression in combined retina + RPE. Starting 24 days after normal eye opening, three groups of juvenile tree shrews (n = 7 each) wore a monocular -5 D lens...

BACKGROUND: Suppressors of cytokine signaling (SOCS) and brain-derived neurotrophic factor (BDNF) are important immunologic, and neurotrophic factors for MS pathogenesis. The impact of exercise on these factors is yet to be fully elucidated in patients with MS. OBJECTIVE: The primary aim of this study is to investigate the effect of 8-week combined exercise training on serum concentrations of SOCS1, SOCS3, and BDNF. The secondary aim is to determine the effects of combined exercise training on balance, functional exercise capacity, and fatigue in patients with MS...

Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease manifested by overtly scarred peripheral and basilar regions and more normal-appearing central lung areas. Lung tissues from macroscopically normal-appearing (IPFn) and scarred (IPFs) areas of explanted IPF lungs were analyzed by RNASeq and compared with healthy control (HC) lung tissues. There were profound transcriptomic changes in IPFn compared with HC tissues, which included elevated expression of numerous immune-, inflammation-, and extracellular matrix-related mRNAs, and these changes were similar to those observed with IPFs compared to HC...

Early nutrition plays an important role in development and may constitute a relevant contributor to the onset of obesity in adulthood. The aim of this study was to evaluate the long-term impact of maternal leucine (Leu) supplementation during lactation on progeny in rats. A chow diet, supplemented with 2% Leu, was supplied during lactation (21 days) and, from weaning onwards, was replaced by a standard chow diet. Then, at adulthood (6 months of age), this was replaced with hypercaloric diets (either with high-fat (HF) or high-carbohydrate (HC) content), for two months, to induce obesity...

Unknown remaining time of signal phase at a signalized intersection generally results in extra accelerations and decelerations that increase variations of operating conditions and thus emissions. A cooperative vehicle-infrastructure system can reduce unnecessary speed changes by establishing communications between vehicles and the signal infrastructure. However, the environmental benefits largely depend on drivers' compliance behaviors. To quantify the effects of drivers' compliance rates on emissions, this study applied VISSIM 5...

BACKGROUND: Unlike for acute immune-mediated neuropathies (IN), anti-ganglioside autoantibody (aGAAb) testing has been recommended for only a minority of chronic IN yet. Thus, we used a multiplex semi-quantitative line immunoassay (LIA) to search for aGAAb in chronic-inflammatory demyelinating polyneuropathy (CIDP) and its clinical variants. METHODS: Anti-GAAb to 11 gangliosides and sulfatide (SF) were investigated by LIA in 61 patients with IN (27 typical CIDP, 12 distal-acquired demyelinating polyneuropathy, 6 multifocal-acquired demyelinating sensory/motor polyneuropathy, 10 sensory CIDP, 1 focal CIDP and 5 multifocal-motoric neuropathy), 40 with other neuromuscular disorders (OND) (15 non-immune polyneuropathies, 25 myasthenia gravis), 29 with multiple sclerosis (MS) and 54 healthy controls (HC)...

BACKGROUND: Seasonal affective disorder (SAD) is characterized by seasonally recurring depression. Heightened amygdala activation to aversive stimuli is associated with major depressive disorder but its relation to SAD is unclear. We evaluated seasonal variation in amygdala activation in SAD and healthy controls (HC) using a longitudinal design targeting the asymptomatic/symptomatic phases of SAD. We hypothesized increased amygdala activation to aversive stimuli in the winter in SAD individuals (season-by-group interaction)...

BACKGROUND: Chronic depression (CD) is strongly associated with childhood maltreatment, which has been proposed to lead to inefficient coping styles that are characterized by abnormal affective responsiveness and dysfunctional cognitive attitudes. However, while this notion forms an important basis for psychotherapeutic strategies in the treatment of CD, there is still little direct empirical evidence for a role of altered affective and cognitive reactivity in CD. The present study therefore experimentally investigated affective and cognitive reactivity to two forms of negative mood induction in CD patients versus a healthy control sample (HC)...

Immune thrombocytopenia (ITP) is an autoimmune disease. Mesenchymal stem cells (MSCs) play important roles in the physiology and homeostasis of the haematopoietic system, including supporting megakaryocytic differentiation from CD34+ haematopoietic progenitor cells. Tumour necrosis factor alpha-induced protein 3 (TNFAIP3, also termed A20) plays a key role in terminating NF-κB signalling. Human genetic studies showed that the polymorphisms of the TNFAIP3 gene may contribute to ITP susceptibility. In this study, we showed a significant decrease in TNFAIP3 and increase in NF-κB/SMAD7 in ITP-MSCs...
