Objective: Deficient brain-derived neurotrophic factor (BDNF) is one of the important mechanisms underlying the neuroplasticity abnormalities in schizophrenia. Aberration in BDNF signaling pathways directly or circuitously influences neurotransmitters like glutamate and gamma-aminobutyric acid (GABA). For the first time, this study attempts to construct and simulate the BDNF-neurotransmitter network in order to assess the effects of BDNF deficiency on glutamate and GABA. Methods: Using CellDesigner, we modeled BDNF interactions with calcium influx via N-methyl-D-aspartate receptor (NMDAR)- Calmodulin activation; synthesis of GABA via cell cycle regulators protein kinase B, glycogen synthase kinase and β-catenin; transportation of glutamate and GABA...

Adipogenesis in murine preadipocyte 3T3L-1 has been used as a model system to study anti-obese bioactive molecules. During adipogenesis in 3T3-L1 preadipocytes, we found that capsanthin inhibited adipogenesis (IC₅₀; 2.5 μM) and also showed lipolytic activity in differentiated adipocytes from the preadipocytes (ED₅₀; 872 nM). We identified that the pharmacological activity of capsanthin on adipogenesis in 3T3-L1 was mainly due to its adrenoceptor-β₂-agonistic activity. In high-fat diet animal model study, capsanthin significantly enhanced spontaneous locomotive activities together with progressive weight-loss...

BACKGROUND: Studies on diagnostic tests for exercise-induced bronchoconstriction (EIB) have centered around the asthmatic and elite athletic population. Traditionally, the exercise challenge test (ET) was recommended to assess EIB. We aimed to compare the performance of surrogate testing, mainly the hypertonic saline (HS) test, and methacholine challenge test (MCT) versus ET in identifying EIB among non-athletic subjects. METHODS: We prospectively recruited subjects who did not have confirmed active asthma, but who reported exercise-induced dyspnoea...

A stable 3D Tb(III)-based metal-organic framework [Tb(BPDC)2]*(CH3)2NH2 (DUT-101) was synthesized, and it is the first efficient dual-channel luminescence sensor for aqueous UO22+ ion. DUT-101 possesses an anionic three-dimensional framework and protonated dimethylamine molecules embedded within the channels. Intense green emission of DUT-101 could be highly selectively and sensitively quenched by UO22+ ions even in the coexistence of other competing metal ions. The possible sensing mechanism was proposed as well based on both suppression of luminescence resonance energy transfer and enhancement of intermolecular electronic transfer...

OBJECTIVES: Central sensitization (CS) implies increased sensitivity of the nervous system, resulting in increased pain sensitivity as well as widespread pain. Recently, the Central Sensitization Inventory (CSI) was developed to assess symptoms of CS and central sensitivity syndromes. The aim of this study was to examine the convergent validity of the CSI by comparing the outcome to psychosocial factors and clinical features of CS. METHODS: In a cross-sectional explorative study, patients with chronic pain completed multiple questionnaires, including the CSI, pain catastrophizing scale, SCL-90 for psychological distress, duration of pain, intensity of pain, widespread pain, and lateralization of pain...

BACKGROUND: Malignant pleural mesothelioma is a rare tumor with a dismal prognosis, usually presenting with recurrent effusions. However, the majority of malignant pleural effusions are due to lung adenocarcinoma (AdC). The distinction between these tumors has considerable therapeutic and medicolegal implications and can be very challenging both histologically and cytologically. Appropriate immunohistochemistry (IHC) is required to support the diagnosis. MicroRNA (miRNA) expression analysis could be a viable diagnostic tool for distinguishing between these tumors...

Targeted next-generation-sequencing (NGS) panels have largely replaced Sanger sequencing in clinical diagnostics. They allow for the detection of copy number variations (CNVs) in addition to single-nucleotide-variants and small insertions/deletions. However, existing computational CNV detection methods have shortcomings regarding accuracy, quality control, incidental findings, and user-friendliness. We developed panelcn.MOPS, a novel pipeline for detecting CNVs in targeted NGS panel data. Using data from 180 samples, we compared panelcn...

Pediatric melanoma, although rare, is the most common skin cancer in children. Our current knowledge on pediatric melanoma incidence trends is expanding, as several studies have addressed this issue with conflicting results. Known risk factors for pediatric melanoma include family history of melanoma, a previous history of malignancy, large congenital nevi, numerous melanocytic nevi, sunburns, increased UV exposure and a sun-sensitive phenotype. In younger children melanoma more often presents with atypical features, such as a changing, amelanotic or uniformly colored, often bleeding lesion, not fulfilling in most cases the conventional ABCDE criteria...
