Mood disorder patients frequently experience difficulty making decisions and may make sub-optimal decisions with adverse life consequences. However, patients' styles for decision-making when ill and after treatment have received little study to date. We assessed healthy controls (HC, n = 69) and patients with major depressive disorder (MDD, n = 61) or bipolar disorder (BP, n = 26) in a current major depressive episode using the Melbourne Decision-making Questionnaire. A subset of participants was re-evaluated after completing six weeks of pharmacotherapy...

Xyloglucan endotransglucosylase (XET) activity, which cuts and re-joins hemicellulose chains in the plant cell wall, contributing to wall assembly and growth regulation, is the major activity of XTH proteins. During purification, XTHs often lose XET activity which, however, is restored by treatment with certain cold-water-extractable, heat-stable polymers (CHPs), e.g. from cauliflower florets. It was not known whether the XTH-activating factor (XAF) present in CHPs works by promoting (e.g. allosterically) XET activity or by re-solubilising sequestered XTH proteins...

In normal settings, our brain is able to update its stored representations in content, strength, and/or expectations by the memory reconsolidation process. Thus, a reactivated memory enters in a transient labile state (destabilization) followed by a re-stabilization phase in order to persist (memory reconsolidation). Cognitive neuroscience and its insight into psychiatric problems attributed a close relationship between memory (formation, maintenance, and utilization) and several mental disorders. In this framework, the reconsolidation process could be not only the mechanism for maintenance of some psychopathologies, but also open a novel therapeutic window...

To investigate the associations between midlife work-related stress and late-life cognition in individuals without dementia from the general population. The Cardiovascular Risk Factors, Aging and Dementia (CAIDE) study population (n = 2000) was randomly selected from independent Finnish population-based surveys (baseline mean age 50 years). Participants underwent two re-examinations in late life (mean age 71 and 78 years, respectively). 1511 subjects participated in at least one re-examination (mean total follow-up 25 years)...

REVIEW
M Beatriz S Lopes
The 4th edition of the World Health Organization (WHO) classification of endocrine tumors has been recently released. In this new edition, major changes are recommended in several areas of the classification of tumors of the anterior pituitary gland (adenophypophysis). The scope of the present manuscript is to summarize these recommended changes, emphasizing a few significant topics. These changes include the following: (1) a novel approach for classifying pituitary neuroendocrine tumors according to pituitary adenohypophyseal cell lineages; (2) changes to the histological grading of pituitary neuroendocrine tumors with the elimination of the term "atypical adenoma;" and (3) introduction of new entities like the pituitary blastoma and re-definition of old entities like the null-cell adenoma...

INTRODUCTION: Exchange nailing is most acceptable for treating hypertrophic non-union of the long bones, requiring the removal of previously fixed implant. However, its main effect of mechanical stabilization is controversial in non-isthmal area. We hypothesized that minimally invasive plate augmentation over the non-union site may have a better option, without the need of bone grafting or removing pre-existing implants. MATERIALS AND METHODS: Seventeen patients with hypertrophic non-union of the long bones between 2010 and 2014 on radiography who previously underwent intramedullary (IM) nailing or plate osteosynthesis for long-bone fractures were included...

StarD7 facilitates phosphatidylcholine (PC) transfer to mitochondria, and is essential for mitochondrial homeostasis. However, the molecular mechanism for PC transfer by protein remains poorly understood. Herein, we describe a putative novel transmembrane (TM) domain C-terminal to the mitochondria-targeting signal (MTS) sequence at the N-terminus of StarD7. The mature form of StarD7 is integrated and/or associated onto the outer leaflet of the outer mitochondrial membrane (OMM) in HEPA-1 and HepG2 cells. A truncated form of StarD7 lacking the TM domain is distributed in the inner space of the mitochondria, and cannot reverse mitochondrial abnormalities, such as complex formation and PC content, when re-expressed in StarD7-KO HEPA-1 cells...

Long-term potentiation (LTP) has been known to be a mechanism by which experience modifies synaptic responses in the neocortex. Visual deprivation in the form of dark exposure or dark rearing from birth enhances NMDAR-dependent LTP in layer 2/3 of visual cortex, a process often termed metaplasticity, which may involve changes in NMDAR subunit composition and function. However, the effects of re-exposure to light after dark rearing from birth on LTP induction have not been explored. Here, we showed that the light exposure after dark rearing revealed a novel NMDAR independent form of LTP in the layer 2/3 pyramidal cells in visual cortex of mice of both sexes which is dependent on mGluR5 activation and is associated with intracellular Ca2+ rise, CaMKII activity, PKC activity and intact protein synthesis...

Gammaherpesviruses (γΗVs) have a dynamic strategy for life-time persistence, involving productive infection, latency, and intermittent reactivation. In latency reservoirs, such as B lymphocytes, γΗV exists as a viral episome and expresses few viral genes. Although the ability of γHV to reactivate from latency and re-enter the lytic phase is challenging to investigate and control, it is known that the γΗV replication and transcription activator, RTA, can promote lytic reactivation. In this study, we provide first evidence that RTA of murine γΗV 68 (MHV68) selectively binds and enhances the activity of tyrosine-phosphorylated host STAT3...

The adequate risk stratification in thyroid carcinoma, is crucial to avoid on one hand the overtreatment of low-risk and on the other hand the undertreatment of high-risk patients. The question how to properly assess the risk of relapse has been discussed during recent years and resulted in a substantial change in our approach to risk stratification in differentiated thyroid cancer, proposed by the newest ATA guidelines. First initial risk stratification, based on histopathological data is carried out just after primary surgery...

mTORC1 inhibitors are promising agents for neuroblastoma therapy, however they have shown limited clinical activity as monotherapy, thus rational drug combinations need to be explored to improve efficacy. Importantly, neuroblastoma maintains both an active p53 and an aberrant mTOR signaling. <br /><br />Experimental Design: Using an orthotopic xenograft model and modulating p53 levels, we investigated the anti-tumor effects of the mTORC1 inhibitor temsirolimus in neuroblastoma expressing normal, decreased, or mutant p53, both as single agent and in combination with first and second generation MDM2 inhibitors to reactivate p53...

Quaternary ammonium hydroxide (QAH) solution has been used to dissolve cellulose and made great progress in recent years. While, its cellulose dissolution mechanism is still in unclear. Here, series of QAH with varied cationic alkyl chains were chosen for the investigation. The solubility of cellulose in QAH was measured, which allowed us to study the effect of cationic structure on cellulose dissolution. Also, the Kamlet-Taft parameters as well as 1D and 2D NMR analyses of QAH-cellulose/cellobiose system were measured...

Ribosomopathies comprise a heterogeneous group of hematologic and developmental disorders, often characterized by bone marrow failure, skeletal and other developmental abnormalities and cancer predisposition. They are associated with mutations and/or haplo-insufficiencies of ribosomal proteins (RPs) and inefficient ribosomal RNA (rRNA) processing. The resulting ribosomal stress induces the canonical p19ARF/Mdm2/p53 tumor suppressor pathway leading to proliferative arrest and/or apoptosis. It has been proposed that this pathway is then inactivated during subsequent neoplastic evolution...

BACKGROUND: In April, 2004, chikungunya virus (CHIKV) re-emerged in Kenya and eventually spread to the islands in the Indian Ocean basin, South-East Asia, and the Americas. The virus, which is often associated with high levels of viremia in humans, is mostly transmitted by the urban vector, Aedes aegypti. The expansion of CHIKV presents a public health challenge both locally and internationally. In this study, we investigated the ability of Ae. aegypti mosquitoes from three distinct cities in Kenya; Mombasa (outbreak prone), Kisumu, and Nairobi (no documented outbreak) to transmit CHIKV...

Thiostrepton (TSR), an archetypal member of the family of ribosomally synthesized and post-translationally modified thiopeptide antibiotics, possesses a biologically important quinaldic acid (QA) moiety within the side-ring system of its characteristic thiopeptide framework. QA is derived from an independent L-Trp residue; however, its associated transformation process remains poorly understood. We here report that during the formation of QA, the key expansion of an indole to a quinoline relies on the activities of the pyridoxal-5'-phosphate-dependent protein TsrA and the flavoprotein TsrE...

A 21-year-old man with Wolff-Parkinson-White syndrome presented to the authors' hospital with ventricular fibrillation. Coronary angiography failed to demonstrate coronary stenosis, but temporary mechanical circulatory support resolved the ventricular fibrillation and the patient was extubated eight days later. On the next day, however, he had to be re-intubated with symptoms of congestive heart failure. Echocardiography revealed new severe mitral regurgitation and a mobile mass, while emergency surgery revealed a posteromedial papillary muscle rupture (PMR)...

Percutaneous coronary intervention (PCI) has become a standard treatment in patients with acute coronary syndrome. However, it is associated with endothelial cell denudation, which may predispose to in-stent thrombosis and restenosis. Pharmacological methods which prevent restenosis can delay post-PCI re-endothelialisation. We have therefore examined how atorvastatin (HMG-CoA reductase inhibitor), sirolimus and everolimus (mTOR inhibitors) affect young and old endothelial cell functions which are responsible for wound healing after PCI...

Objectives The use of postoperative anticoagulation is not uncommon for patients undergoing lower extremity arterial procedures as adjunctive therapy. Longer postoperative length of stay is necessary to achieve adequate therapeutic international normalized ratio with traditional protocols that call for the use of unfractionated heparin and warfarin therapy. We hypothesized the direct oral anticoagulants are an attractive alternative to provide adequate anticoagulation in patients who undergo lower extremity arterial procedures...
