BACKGROUND: The Emotion Regulation Skills Questionnaire (ERSQ) comprehensively assesses nine aspects of emotion regulation skills: awareness, clarity, sensation, understanding, compassionate self-support, modification, acceptance, tolerance, and readiness to confront. However, it is unknown about the levels of emotion regulation skills in various mental disorders, and its cross-cultural validity. We developed a Japanese version of the ERSQ, then examined its validity and reliability in clinical and non-clinical populations...

During immune responses antigen-specific T cells are regulated by several mechanisms, including through inhibitory receptors and regulatory T cells, to avoid excessive or persistent immune responses. These regulatory mechanisms, which are called 'immune checkpoints', suppress T cell responses, particularly in patients with chronic viral infections and cancer where viral antigens or tumor antigens persist for a long time and contribute to T cell exhaustion. Among these regulatory mechanisms, cytotoxic T lymphocyte associated protein-4 (CTLA-4) and programmed cell death 1 (PD-1) are the most well-known receptors and both have been targeted for drug development...

The introduction of collagenase Clostridium histolyticum (CCH) as a treatment option for Peyronie's disease (PD), defined as the abnormal formation of collagen on the tunica albuginea of the penis, has provided patients with a promising new conservative therapy. Studies have shown that CCH improves curvature by an average of 17°, and although patient and sexual partner satisfaction is high, the improvement has arguable clinical implications. Similarly, the efficacy and cost of CCH contrasts strongly with more invasive surgical management, and is further limited by rare, but serious, complications and several contraindications...

Rapid eye movement sleep behavior disorder (RBD) is thought to be one of the most frequent preceding symptoms of Parkinson's disease (PD). However, the prevalence of RBD in PD stated in the published studies is still inconsistent. We conducted a meta and meta-regression analysis in this paper to estimate the pooled prevalence. We searched the electronic databases of PubMed, ScienceDirect, EMBASE and EBSCO up to June 2016 for related articles. STATA 12.0 statistics software was used to calculate the available data from each research...

Clock (Clk)1/COQ7 is a mitochondrial hydroxylase that is necessary for the biosynthesis of ubiquinone (coenzyme Q or UQ). Here, we investigate the role of Clk1 in neuroinflammation and consequentially dopaminergic (DA) neuron survival. Reduced expression of Clk1 in microglia enhanced the LPS-induced proinflammatory response and promoted aerobic glycolysis. Inhibition of glycolysis abolished Clk1 deficiency-induced hypersensitivity to the inflammatory stimulation. Mechanistic studies demonstrated that mTOR/HIF-1α and ROS/HIF-1α signaling pathways were involved in Clk1 deficiency-induced aerobic glycolysis...

INTRODUCTION: Alpha-synuclein pathology (ASP) is a characteristic histopathological finding in idiopathic Parkinson's disease (PD). The ASP involves not only the brain but also extracranial structures. In the present study we utilized MIBG scintigraphy to measure the sympathetic innervation of the major salivary glands. We were interested in whether MIBG uptake in the major salivary glands represents a potential biomarker for ASP in PD. METHODS: We investigated 77 PD patients (age 61 ± 10 years, mean ± SD), while 15 non-PD patients (age 58 ± 15 years) with arterial hypertension, who underwent MIBG scintigraphy to exclude pheochromocytoma, served as age-matched controls...

Malignant melanoma contributes the majority of skin cancer related deaths and shows an increasing incidence in the past years. Despite all efforts of early diagnosis, metastatic melanoma still has a poor prognosis and remains a challenge for treating physicians. In recent years, improved knowledge of the pathophysiology and a better understanding of the role of the immune system in tumour control have led to the development and approval of several immunotherapies. Monoclonal antibodies against different immune checkpoints have been revolutionizing the treatment of metastatic and unresectable melanoma...

Viral diseases are among the main challenges in farming of Atlantic salmon (Salmo salar). The most prevalent viral diseases in Norwegian salmon aquaculture are heart and skeletal muscle inflammation (HSMI) caused by Piscine orthoreovirus (PRV), and pancreas disease (PD) caused by Salmonid alphavirus (SAV). Both PRV and SAV target heart and skeletal muscles, but SAV additionally targets exocrine pancreas. PRV and SAV are often present in the same locations and co-infections occur, but the effect of this crosstalk on disease development has not been investigated...

BACKGROUND: The phase 3 MPACT trial in patients with metastatic pancreatic cancer demonstrated superior efficacy of nab-paclitaxel (nab-P) + gemcitabine (Gem) vs Gem monotherapy for all endpoints examined including overall survival, the primary endpoint. In the MPACT trial, patients were treated until progressive disease (PD) or unacceptable toxicity. The current exploratory analysis investigated outcomes of patients from the MPACT trial who were treated until PD, in order to understand how to maximize treatment benefit from nab-P + Gem...

BACKGROUND: A disturbed circadian rhythm seems to be a causal factor in the occurrence of depressive disorders in patients with Parkinson's disease (PD). The circadian rhythm can be restored with light. Therefore, Bright Light Therapy (BLT) might be a new treatment option for depression in PD patients. METHODS/DESIGN: In this double-blind controlled trial, 84 subjects with idiopathic PD are randomized to either BLT or a control light condition. The BLT condition emits white light with an intensity of 10,000 Lux, while the control device emits dim white light of 200 Lux, which is presumed to be too low to influence the circadian rhythm...

BACKGROUND: Circulating follicular helper T (Tfh) cells are a heterogeneous population of CD4(+) helper T cells that promotes pathogenic immune responses in autoimmune diseases. In this study, we examined the status of different subpopulations of Tfh cells in peripheral circulation and their associations with various clinical characteristics of IgA vasculitis (IgAV). METHODS: According to the phenotypic expressions of different molecules, focus was given on six subpopulations of Tfh cells: CD4(+)CXCR5(+), CD4(+)CXCR5(+)ICOS(+), CD4(+)CXCR5(+)ICOS(+)PD-1(+), CD4(+)CXCR5(+)ICOS(high)PD-1(high), CD4(+)CXCR5(+)ICOS(-)PD-1(+), and CXCR5(+)CD45RA(-)IL-21(+)...

Increasing rates of antibiotic resistance coupled with the lack of novel antibiotics threatens proper clinical treatment and jeopardizes their use in prevention. A photodynamic approach appears to be an innovative treatment option, even for multi-drug resistant strains of bacteria. Three components are utilized in photodynamic inactivation: a photosensitizer, light source, and oxygen. Variations in photosensitizers strongly influence microbial binding and bactericidal activity. In this study, four different cationic metalloporphyrins (Cu(2+), Fe(2+), Pd(2+), Zn(2+)) were compared to the free-base ligand 5,10,15,20-tetrakis(N-methylpyridinium-4-yl)porphyrin regarding their electronic properties and generation of reactive oxygen species upon subsequent 405nm violet-blue irradiation...

OBJECTIVE: To examine whether pancreaticogastrostomy (PG) or pancreaticojejunostomy (PJ) is the best reconstruction method to reduce occurrence of postoperative complications, especially pancreatic fistula (PF), after pancreaticoduodenectomy (PD). BACKGROUND: PF is one of the most severe complications after PD. The best reconstruction method to reduce occurrence of PF is controversial. Therefore, we carried out this meta-analysis to compare PG with PJ. METHODS: A systematic review was conducted in PubMed, EMBASE, and Cochrane Library to identify studies comparing PG with PJ, published up to October 2015...

BACKGROUND: Peritonitis and ultrafiltration failure remain serious complications of chronic peritoneal dialysis (PD). Dysfunctional cellular stress responses aggravate peritoneal injury associated with PD fluid exposure, potentially due to peritoneal glutamine depletion. In this randomized cross-over phase I/II trial we investigated cytoprotective effects of alanyl-glutamine (AlaGln) addition to glucose-based PDF. METHODS: In a prospective randomized cross-over design, 20 stable PD outpatients underwent paired peritoneal equilibration tests 4 weeks apart, using conventional acidic, single chamber 3...

Ipilimumab, a fully human monoclonal antibody against cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), is the first immune checkpoint inhibitor approved for the treatment of unresectable melanoma on the basis of its overall survival (OS) benefit. However, ipilimumab is associated with significant immune-related adverse events. We hypothesized that biomarker exploration of pretreatment tumor samples and correlation with clinical outcome would enable patient selection with an increased benefit/risk ratio for ipilimumab therapy...

We determined the parameters of a classical spin Hamiltonian describing an Fe monolayer on Pd(111) surface with a Pt_{1-x}Ir_{x} alloy overlayer from ab initio calculations. While the ground state of the system is ferromagnetic for x=0.00, it becomes a spin spiral state as Ir is intermixed into the overlayer. Although the Dzyaloshinsky-Moriya interaction is present in the system, we will demonstrate that the frustrated isotropic exchange interactions play a prominent role in creating the spin spiral state, and these frustrated couplings lead to an attractive interaction between Skyrmions at short distances...

Trisubstituted α-pyrones are obtained by a Pd-catalyzed three-component, single-flask operation via an α-arylation, subsequent α-alkenylation, alkene isomerization, and dienolate lactonization. A variety of coupling components under mild conditions afforded isolated yields of up to 93% of the pyrones with complete control of regioselectivity. Metal dependence was noted for three of the steps of the pathway. Utility of the pyrone products was demonstrated by further transformations providing convenient access to polyaromatic compounds, exhibiting broad molecular diversity...
