Nicotinamide riboside first alleviates symptoms but later downregulates dopamine metabolism in proteasome inhibition mouse model of Parkinson's disease.

Parkinson's disease (PD) is associated with a reduction in 26/20S proteasome and mitochondrial function and depletion of dopamine. Activation of mitochondrial function with the NAD precursor nicotinamide riboside (NR) is a potential therapeutic for PD. However, despite recently started clinical trials, analysis of NR in mammalian animal PD models is lacking and data in simpler PD models is limited.

Pregnane X Receptor‒4β-Hydroxycholesterol Axis in the Regulation of Overweight- and Obesity-Induced Hypertension.

Background Mechanisms mediating hypertensive effects of overweight and obesity have not been fully elucidated. We showed previously that activation of pregnane X receptor (PXR) by rifampicin elevates 24-hour blood pressure (BP) and plasma 4β-hydroxycholesterol (4βHC), agonist for liver X receptor (LXR). Methods and Results In combined "PXR activation data set" (n=62) of 4 clinical trials, 1 week rifampicin dosing increased office systolic BP (SBP) by 3.

Optimism in adults born preterm: Systematic review and individual-participant-data meta-analysis.

Aim: Preterm birth(<37 gestational weeks) is associated with numerous adversities, however, data on positive developmental outcomes remain limited. We examined if preterm and term born(≥37 gestational weeks) adults differ in dispositional optimism/pessimism, a personality trait associated with health and wellbeing. We assessed if birth weight z-score, neurosensory impairments and parental education modified the outcome.

Mental health outcomes of adults born very preterm or with very low birth weight: A systematic review.

Preterm birth research is poised to explore the mental health of adults born very preterm(VP; <32 weeks gestational age) and/or very low birth weight(VLBW; <1500g) through individual participant data meta-analyses, but first the previous evidence needs to be understood. We systematically reviewed and assessed the quality of the evidence from VP/VLBW studies with mental health symptoms or disorders appearing in adulthood, excluding childhood onset disorders. Participants (≥18 years, born >1970) included VP/VLBW individuals with controls born at term(≥37 weeks) or with normal birth weight(NBW; ≥2500g).

Novel Screening Method Identifies PI3Kα, mTOR, and IGF1R as Key Kinases Regulating Cardiomyocyte Survival.

Background Small molecule kinase inhibitors (KIs) are a class of agents currently used for treatment of various cancers. Unfortunately, treatment of cancer patients with some of the KIs is associated with cardiotoxicity, and there is an unmet need for methods to predict their cardiotoxicity. Here, we utilized a novel computational method to identify protein kinases crucial for cardiomyocyte viability.

Prognostic Impact of Multiple Prior Percutaneous Coronary Interventions in Patients Undergoing Coronary Artery Bypass Grafting.

Background Multiple percutaneous coronary interventions ( PCIs ) are considered determinant of poor outcome in patients undergoing coronary artery bypass grafting ( CABG ), but scarce data exist to substantiate this. Methods and Results Patients who underwent CABG without history of prior PCI or with PCI performed >30 days before surgery were selected for the present analysis from the prospective, multicenter E-CABG (European Multicenter Study on Coronary Artery Bypass Grafting) registry. Out of 6563 patients with data on preoperative SYNTAX (Synergy between PCI With Taxus and Cardiac Surgery) score, 1181 patients (18.

The 1 Baltic Osseointegration Academy and Lithuanian University of Health Sciences Consensus Conference 2016. Summary and Consensus Statements: Group I - Peri-Implantitis Aetiology, Risk Factors and Pathogenesis.

Introduction: The task of Group 1 was to review and update the existing data concerning aetiology, risk factors and pathogenesis of peri-implantitis. Previous history of periodontitis, poor oral hygiene, smoking and presence of general diseases have been considered among the aetiological risk factors for the onset of peri-implant pathologies, while late dental implant failures are commonly associated with peri-implantitis and/or with the application of incorrect biomechanical forces. Special interest was paid to the bone cells dynamics as part of the pathogenesis of peri-implantitis.

The Prosthetic Influence and Biomechanics on Peri-Implant Strain: a Systematic Literature Review of Finite Element Studies.

Objectives: To systematically review risks of mechanical impact on peri-implant strain and prosthetic influence on stability across finite element studies.

Material And Methods: An online literature search was performed on MEDLINE and EMBASE databases published between 2011 and 2016. Following keywords tiered screening and selection of the title, abstract and full-text were performed.

Slug is associated with poor survival in squamous cell carcinoma of the lung.

We investigated the expression of slug in a large set of lung squamous and adenocarcinomas to determine common or dissimilar features in its expression in these two most common forms of lung cancer. To investigate slug related tumor spread we studied the expression of vimentin, claudin 1, MMP2 and MMP9 in these tumors and their relation to slug. Addition, cell invasion assays, mRNA analysis and zymographic tests were performed to study epitheliomesenchymal transition (EMT) related changes in slug blocked lung cell lines.
