Inflammatory processes play a crucial role in the pathophysiology of depression, and identifying the specific cytokines targeted by different antidepressants is important for personalized treatment. The aims of this study were to examine whether venlafaxine and paroxetine cause different immunomodulatory effects when used to treat patients with major depression and to clarify the relationships between plasma cytokine levels and the therapeutic effectiveness of these drugs. A total of 91 Han Chinese patients with major depression completed the 8-week paroxetine or venlafaxine treatment and 90 healthy controls were recruited...

(223) Radium ((223) Ra) is widely used in Nuclear medicine to treat patients with osseous metastatic prostate cancer. In clinical practice (223) Ra cannot be imaged directly, however gamma photons produced by its short-lived daughter nuclides can be captured by conventional gamma cameras. In this work we show that (223) Ra and its short-lived daughter nuclides can be detected with optical imaging techniques. The light emission of (223) Ra was investigated in vitro using different setups in order to clarify the mechanism of light production...

Background -Radiation exposure during fluoroscopically-guided interventions such as endovascular aortic repair (EVAR) is a growing concern for operators. This study aimed to measure DNA damage/repair markers in operators perfoming EVAR. Methods -Expression of the DNA damage/repair marker, gamma-H2AX (γ-H2AX) and DNA damage response (DDR) marker, phosphorylated ataxia telangiectasia mutated (pATM), were quantified in circulating lymphocytes in operators during the peri-operative period of endovascular (infra-renal [IEVAR], branched [BEVAR] and fenestrated [FEVAR]) and open aortic repair using flow cytometry...

Microtubules in animal cells assemble (nucleate) from both the centrosome and the cis-Golgi cisternae. A-kinase anchoring protein 350 KDa (AKAP350A, also called AKAP450/CG-NAP/AKAP9) is a large scaffolding protein located at both the centrosome and Golgi apparatus. Previous findings have suggested that AKAP350 is important for microtubule dynamics at both locations, but how this scaffolding protein assembles microtubule nucleation machinery is unclear. Here, we found that overexpression of the C-terminal third of AKAP350A, EGFP-AKAP350A(2691-3907), induces the formation of multiple microtubule-nucleation centers (MTNCs)...

Diet-associated insulin resistance (IR) is intimately correlated to the progression of metabolic syndrome and hippocampal dysfunction. Pioglitazone (PIO), a selective peroxisome proliferator-activated receptor gamma (PPARγ) agonist, has been applied to enhance insulin sensitivity. With limited permeability to blood-brain-barrier, it is unclear that whether oral PIO available to cure both the peripheral IR and the impairment in hippocampus. We evaluated the levels of peripheral and hippocampal IR via the homeostatic model assessment of insulin resistance and hippocampal IRS-1/Akt phosphorylation, respectively, of Wistar Kyoto rats fed with regular chew or high fructose diet (HFD) for 12weeks...

Chrysin is a natural flavonoid which is found in bee propolis, honey and various plants, and neuroprotective effect of chrysin in mice was previously demonstrated by our group. Neuroinflammation, neurotrophic factors and neuronal recovery factors associated with the neuroprotective effect of this flavonoid require further investigations. Thus, now we investigated the possible involvement of inflammatory cytokines, neurotrophic factors and neuronal recovery in the effect of chrysin in 6-hydroxidopamine (6-OHDA), a well-established model of Parkinson's disease, in striatum of mice...

Pharmacological administration is commonly used when conducting whole-cell patch-clamp recording in brain slices. One of the best methods of drug application during electrophysiological recording is the puff technique, which can be used to study the effect of pharmacological reagents on neuronal activities in brain slices. The greatest advantage of puff application is that the drug concentration around the recording site increases rapidly, thus preventing desensitization of membrane receptors. Successful use of puff application involves careful attention to the following elements: the concentration of the drug, the parameters of the puff micropipette, the distance between the tip of a puff micropipette and the neuron recorded, and the duration and pressure driving the puff (pounds per square inch, psi)...

Mechanisms underlying functional recovery after stroke are little known, and effective drug intervention during the delayed stage is desirable. One potential drug target, the protein-protein interaction between neuronal nitric oxide synthase (nNOS) and postsynaptic density protein 95 (PSD-95), is critical to acute ischaemic damage and neurogenesis. We show that nNOS-PSD-95 dissociation induced by microinjection of a recombinant fusion protein Tat-nNOS-N1-133 or systemic administration of a small molecule ZL006 from days 4 to 10 after photothrombotic ischaemia in mice reduced excessive tonic inhibition in the peri-infarct cortex and ameliorated motor functional outcome...

To assess the specific roles of left middle frontal gyrus (LMFG) in word production, electrocorticography signals were recorded from an epilepsy patient when he participated in language tasks. We found three sites of LMFG showed high-gamma perturbations with distinct patterns across tasks; and neural activities elicited in the same tasks shared similar patterns, while those elicited by stimuli leading to the same articulations did not. These findings confirmed that the LMFG takes active parts in word production, and suggested that it may serve as a temporal perceptual information storage space, supporting the hierarchical state feedback control model of word production...

Analyses using a nationally representative cohort have revealed that high fatty liver index (FLI) is associated with low bone mineral density (BMD) regardless of insulin resistance in men, thereby supporting the deteriorated bone metabolism in nonalcoholic fatty liver disease (NAFLD). INTRODUCTION: NAFLD is linked to deteriorated bone health. We investigated the association of FLI, a scoring model for NAFLD, with BMD. METHODS: This was a population-based, cross-sectional study from the Korea National Health and Nutrition Examination Surveys including 4264 Koreans (1908 men and 2356 women)...

Abuse of methamphetamine (METH), a powerful addictive amphetamine-type stimulants (ATS), is becoming a global public health problem. The gamma-aminobutyric acid (GABA)ergic system plays a critical role in METH use disorders. By using rat METH conditioned place preference (CPP) model, we previously demonstrated that METH-associated rewarding memory formation was associated with the reduction of GABAAα1 expression in the dorsal straitum (Dstr), however, the underlying mechanism was unclear. In the present study, we found that METH-induced CPP formation was accompanied by a significant increase in the expression of Synovial apoptosis inhibitor 1 (SYVN1), an endoplasmic reticulum (ER)-associated degradation (ERAD) E3 ubiquitin ligase, in the Dstr...

Spontaneous activity of serotonergic neurons of the dorsal raphe nucleus (DRN) regulates mood and motivational state. Potentiation of serotonergic function is one of the therapeutic strategies for treatment of various psychiatric disorders, such as major depression, panic disorder and obsessive-compulsive disorder. However, the control mechanisms of the serotonergic firing activity are still unknown. In this study, we examined the control mechanisms for serotonergic spontaneous activity and effects of chronic antidepressant administration on these mechanisms by using modified ex vivo electrophysiological recording methods...

Molecular targeted therapeutical and imaging strategies directed at aberrant signaling-pathways in pancreatic tumor cells may improve the poor outcome of pancreatic ductal adenocarcinoma (PDA). Therefore, relevant molecular targets need to be identified. Methods: We collected publicly available expression profiles of patient derived normal pancreatic tissue (n = 77) and PDA samples (n = 103). Functional Genomic mRNA (FGmRNA) profiling was applied to predict target upregulation on the protein level. We prioritized these targets based on current status of (pre)-clinical therapeutical and imaging evaluation in PDA...

Overexpression of γ-tubulin leads to the formation of filaments, but nothing is known about such filaments with regard to possible presence in cells, structure and probable dynamics. Here, we used mammalian cell lines to investigate the ability of γ-tubulin to form filaments. We found that γ-tubulin produces fibers called γ-tubules in a GTP-dependent manner and that γ-tubules are made up of pericentrin and the γ-tubulin complex proteins 2, 3, 5 and 6. Furthermore, we noted that the number of cells with cytosolic γ-tubules is increased in non-dividing cells...

Interferon gamma release assays (IGRAs) have been widely used to diagnose Mycobacterium tuberculosis (MTB) infection. However, IGRAs cannot discriminate between active TB patients and latent TB infection (LTBI), and the sensitivity of IGRAs for MTB infection is suboptimal. Here, we analyzed cytokines/chemokines in MTB antigen-stimulated and -unstimulated plasma samples to identify host biomarkers that are associated with active TB and MTB infection. Active TB patients, subjects with LTBI and healthy participants were recruited...
