Hippocampus is innervated by γ-aminobutyric acid (GABA) 'projection' neurons of the nucleus incertus (NI), including a population expressing the neuropeptide, relaxin-3 (RLN3). In studies aimed at gaining an understanding of the role of RLN3 signaling in hippocampus via its Gi/o -protein-coupled receptor, RXFP3, we examined the distribution of RLN3-immunoreactive nerve fibres and RXFP3 mRNA-positive neurons in relation to hippocampal GABA neuron populations. RLN3-positive elements were detected in close-apposition with a substantial population of somatostatin (SST)- and GABA-immunoreactive neurons, and a smaller population of parvalbumin- and calretinin-immunoreactive neurons in different hippocampal areas, consistent with the relative distribution patterns of RXFP3 mRNA and these marker transcripts...

The aim of this study was to determine the effects and molecular mechanism of blue light emitting diode (LED) in tumor cells. A migration and invasion assay for the metastatic behavior of mouse colon cancer CT-26 and human fibrosarcoma HT-1080 cells was performed. Cancer cell migration-related proteins were identified by obtaining a 2-dimensional gel electrophoresis (2-DE) in total cellular protein profile of blue LED-irradiated cancer cells, followed by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) analysis of proteins...

BACKGROUND: Recent reports have demonstrated that binge-like ethanol drinking leads to an increase in hypothalamic orexin (OX) signaling and that suppressing this signaling via systemic administration of an orexin receptor (OXR) antagonist blocks this behavior; however, the specific OX pathways that modulate this behavior remain unknown. The goal of the present study was to further elucidate the role of the OX system in binge-like ethanol drinking using behavioral, molecular, and pharmacological techniques...

PURPOSE: The purpose of this work was to establish an empirical model of the ion recombination in the Advanced Markus ionization chamber for measurements in high dose rate/dose-per-pulse electron beams. In addition, we compared the observed ion recombination to calculations using the standard Boag two-voltage-analysis method, the more general theoretical Boag models, and the semi-empirical general equation presented by Burns and McEwen. METHODS: Two independent methods were used to investigate the ion recombination: 1) Varying the grid tension of the linear accelerator (linac) gun (controls the linac output) and measuring the relative effect the grid tension has on the chamber response at different source-to-surface distances (SSD)...

Poly(ethylene glycol) (PEG) hydrogels provide a versatile platform to develop cell instructive materials through incorporation of a variety of cell adhesive ligands and degradable chemistries. Synthesis of PEG gels can be accomplished via two mechanisms: chain and step growth polymerizations. The mechanism dramatically impacts hydrogel nanostructure, whereby chain polymerized hydrogels are highly heterogeneous and step growth networks exhibit more uniform structures. Underpinning these alterations in nanostructure of chain polymerized hydrogels are densely-packed hydrophobic poly(methyl methacrylate) or poly(acrylate) kinetic chains between hydrophilic PEG crosslinkers...

Aromatase catalyzes the conversion of testosterone to estradiol and is involved in physiological effects of sex hormones on brain functions. Animal experiments have shown that the aromatase inhibitor, letrozole, can induce anxiety in young ovariectomized females that are used as a model of aging. Whether or not these effects would be similar in intact middle-aged animals is unknown. The aim of our study was to analyze the effects of letrozole on anxiety in middle-aged rats of both sexes. Fifteen months old male and female rats were treated daily with either letrozole or vehicle for 2 weeks...

OBJECTIVE: To examine whether prosocial behaviors help sustain a positive mood, we tested the dynamic reciprocal associations between prosocial behavior and positive affect (PA) in daily life. A second aim was to examine whether the personality traits neuroticism and extraversion moderate these associations. METHODS: The study included a community sample (N = 553). Participants completed an electronic diary assessing prosocial behavior and PA three times a day over 30 days...

Here, we describe the characteristics of a Pt-blue complex [Pt4 (2-atp)8 (H2 O)(OH)] (2-atp: 2-aminothiophenol) as a prodrug for its DNA-binding properties and its use in cancer therapy. The nature of the interaction between the Pt-blue complex and DNA was evaluated based on spectroscopic measurements, the electronic absorption spectra, thermal behavior, viscosity, fluorometric titration and agarose gel electrophoresis. Our results suggested that the compound was able to partially intercalate DNA and appeared to induce both single and double stranded breaks (DBS) on DNA in vitro, but no DSBs in cells...

In this review we discuss the management of chronic orofacial pain (COFP) patients with insomnia. Diagnostic work-up and follow-up routines of COFP patients should include assessment of sleep problems. Management is based on a multidisciplinary approach, addressing the factors that modulate the pain experience as well as insomnia and including both non-pharmacological and pharmacological modalities. Parallel to treatment, patients should receive therapy for co-morbid medical and psychiatric disorders, and possible substance abuse that may be that may trigger or worsen the COFP and/or their insomnia...

Insecticide resistance is a major obstacle to the management of disease-vectoring mosquitoes worldwide. The genetic changes and detoxification genes involved in insecticide resistance have been extensively studied in populations of insecticide-resistant, however few studies have focused on the resistance genes up-regulated upon insecticide exposure and the possible regulation pathways involved in insecticide resistance. To characterize the changes in gene expression during insecticide exposure, and to investigate the possible connection of known regulation pathways with insecticide resistance, we conducted RNA-Seq analysis of a highly-permethrin resistant strain of Culex quinquefasciatus following permethrin exposure...

Germline mutations in PTPN11, the gene encoding the Src-homology 2 (SH2) domain-containing protein tyrosine phosphatase (SHP2), cause Noonan syndrome (NS), a relatively common, clinically variable, multisystem disorder. Here, we report on the identification of five different PTPN11 missense changes affecting residues Leu(261) , Leu(262) and Arg(265) in 16 unrelated individuals with clinical diagnosis of NS or with features suggestive for this disorder, specifying a novel disease-causing mutation cluster. Expression of the mutant proteins in HEK293T cells documented their activating role on MAPK signaling...

To avoid the fierce competition for food, South African ball-rolling dung beetles carve a piece of dung off a dung-pile, shape it into a ball and roll it away along a straight line path. For this unidirectional exit from the busy dung pile, at night and day, the beetles use a wide repertoire of celestial compass cues. This robust and relatively easily measurable orientation behavior has made ball-rolling dung beetles an attractive model organism for the study of the neuroethology behind insect orientation and sensory ecology...

REVIEW
Andrew H Ford, Osvaldo P Almeida
Depression in the context of dementia is common and contributes to poorer outcomes in individuals and those who care for them. Non-pharmacological treatments are the preferred initial approach to managing these symptoms but data in support of these are scarce. There are a number of pharmacological treatment options available to clinicians but efficacy is uncertain and concern about potential side effects in an aging and vulnerable population needs to be taken into consideration. This review aims to provide a concise overview of pharmacological treatments for depression in dementia...

Few studies have examined the association between smoking behavior (especially quitters) at the time of diagnosis and mortality among cancer patients. Our objective was to examine the benefits of quitting on all-cause mortality among cancer patients. 30,658 eligible cancer patients diagnosed between 1985 and 2009, identified by a hospital-based cancer registry in Japan, were followed up for up to 10 years. We evaluated smoking behavior at cancer diagnosis (especially recent quitters versus current smokers) in association with all-cause mortality using Cox-proportional hazards models and covariates-adjusted survival curves...

Brad Foote, Kim Van Orden
Dialectical Behavior Therapy (DBT), created by Marsha Linehan, has been shown to be an effective therapy for the treatment of borderline personality disorder (BPD) and for suicidal and self-harming behavior. Dissociative identity disorder (DID) is a complex post-traumatic disorder which is highly comorbid with BPD, shares a number of clinical features with BPD, and which like BPD features a high degree of suicidality. The DID treatment literature emphasizes the importance of a staged approach, beginning with the creation of a safe therapeutic frame prior to addressing traumatic material; DBT is also a staged treatment, in which behavioral and safety issues are addressed in Stage 1, and trauma work reserved for Stage 2...
