Faculty of Health Sciences, Universitat Oberta de Catalunya, Av. Tibidabo, 39-43, 08035, Barcelona, Spain; Honorary Fellow, Center for Healthy Minds, University of Wisconsin-Madison, United States. Electronic address:

In the last decade, epigenetics has taken center stage to explain the relationships between stress exposure, health and behavior. Acquired or inherited epigenetic changes modulate gene expression states without modifying the DNA sequence itself, they can be long-lasting, yet, they are potentially reversible. Several studies have explored whether meditation-based interventions can influence gene expression profiles towards healthier directions, identifying candidate genes and biological pathways that seem to be sensitive to contemplative practices.

Activation of mitochondrial aldehyde dehydrogenase (ALDH2) by ALDA-1 reduces both the acquisition and maintenance of ethanol intake in rats: A dual mechanism?

Neuropharmacology 2018 Dec 3. Epub 2018 Dec 3.

Program of Molecular and Clinical Pharmacology, ICBM, Faculty of Medicine, University of Chile, Santiago, Chile.

A number of pre-clinical studies have shown that brain-generated acetaldehyde, the first metabolite of ethanol, exerts reinforcing effects that promote the acquisition of ethanol intake, while chronic intake maintenance appears to be mediated by alcohol-induced brain neuroinflammation/oxidative stress. Recently, it was described that N-(1,3-benzodioxol-5-ylmethyl)-2,6-dichlorobenzamide (ALDA-1) activates aldehyde dehydrogenase-2 (ALDH2), enzyme that catalyzes the oxidation of ethanol-derived acetaldehyde to acetate. The aim of this study was to determine the effects of ALDA-1 on both the acquisition and the maintenance of alcohol intake in alcohol-preferring UChB rats. Read More

3D surface condensation of large atomic shear strain in nanoscale metallic glasses under low uniaxial stress.

J Phys Condens Matter 2019 Jan;31(2):025401

Materials Science Program, School of Mechanical, Industrial and Manufacturing Engineering, Oregon State University, Corvallis, OR 97331, United States of America.

Nanoscale metallic glasses (MGs) are frequently used in experimental and computational studies to probe the deformation mechanisms in amorphous metals. Potential consequences of the significant surface to volume ratio in these extremely small materials, nevertheless, are not well understood. Here, using molecular dynamics simulations and novel selective 3D visualization, we show that significant irreversible atomic shear strain condenses on the 3D surface of these materials under low uniaxial stress, while the interior atoms are bearing much lower, mostly reversible shear strain.

Blocking Tyr265 nitration of protein phosphatase 2A attenuates nitrosative stress-induced endothelial dysfunction in renal microvessels.

FASEB J 2018 Dec 6:fj201800885RR. Epub 2018 Dec 6.

Division of Nephrology, Department of Internal Medicine, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Protein tyrosine (Tyr) nitration, the covalent addition of a nitro group (NO) to Tyr residues, is emerging as a candidate mechanism of endothelial dysfunction. Previous studies have shown that Tyr nitration is primarily induced by nitrosative stress, a process characterized by the production of reactive nitrogen species, especially peroxynitrite anion (ONOO), which is considered a secondary product of NO in the presence of superoxide radicals (O). However, the impact of nitrosative stress-induced Tyr nitration on endothelial dysfunction has not been thoroughly elucidated to date. Read More

Elevated truncated oxidized phospholipids as a factor exacerbating ALI in the aging lungs.

FASEB J 2018 Dec 6:fj201800981R. Epub 2018 Dec 6.

Department of Anesthesiology, University of Maryland School of Medicine, Baltimore, Maryland, USA.

As mechanisms controlling redox homeostasis become impaired with aging, exaggerated oxidant stress may cause disproportional oxidation of cell membranes and circulating phospholipids (PLs), leading to the formation of truncated oxidized PL products (Tr-OxPLs), which exhibit deleterious effects. This study investigated the role of elevated Tr-OxPLs as a factor exacerbating inflammation and lung barrier dysfunction in an animal model of aging. Mass spectrometry analysis of Tr-OxPL species in young (2-4 mo) and aging (18-24 mo) mice revealed elevated basal levels of several products [1-palmitoyl-2-(5-oxovaleroyl)- sn-glycero-phosphocholine (POVPC), 1-palmitoyl-2-glutaroyl- sn-glycero-phosphocholine, lysophosphocholine, 1-palmitoyl-2-(9-oxo-nonanoyl)- sn-glycero-3-phosphocholine, 1-palmitoyl-2-azelaoyl- sn-glycero-3-phosphocholine, O-1-O-palmitoyl-2-O-(5,8-dioxo-8-hydroxy-6-octenoyl)-l-glycero-3-phosphocholine, and others] in the aged lungs.

A single AT-GC exchange can modulate charge transfer-induced p53-DNA dissociation.

Chem Commun (Camb) 2018 Dec 6. Epub 2018 Dec 6.

Department of Chemistry, Duke University, Durham, North Carolina 27708, USA. and Department of Biochemistry, Duke University, Durham, North Carolina 27710, USA and Department of Physics, Duke University, Durham, North Carolina 27708, USA.

Using molecular dynamics simulations and electronic structure theory, we shed light on the charge dynamics that causes the differential interaction of tumor suppressor protein p53 with the p21 and Gadd45 genes in response to oxidative stress. We show that the sequence dependence of this selectivity results from competing charge transfer to the protein and through the DNA, with implications on the use of genome editing tools to influence the p53 regulatory function.

[Usefulness, timing and modality of ECG stress testing after myocardial revascularization].

G Ital Cardiol (Rome) 2018 Dec;19(12):692-704

Istituto di Cardiologia, Università degli Studi, Pisa.

Myocardial revascularization in patients with stable ischemic heart disease aims at eliminating myocardial ischemia, in order to (i) relieve anginal symptoms; (ii) improve functional capacity; and, possibly, (iii) improve prognosis. Given that ischemic recurrences are relatively common in patients undergoing myocardial revascularization, an appropriate follow-up is needed as part of a secondary prevention program. Stress testing can be here useful to: (i) detect residual or recurrent ischemia/angina; (ii) define functional capacity in order to establish physical aerobic training individualized programs; (iii) stratify prognosis.

The transcription factors TFE3 and TFEB amplify p53 dependent transcriptional programs in response to DNA damage.

Elife 2018 Dec 6;7. Epub 2018 Dec 6.

Cell and Developmental Biology Center, National Heart, Lung, and Blood Institute, National Institutes of Health, Bethesda, United States.

The transcription factors TFE3 and TFEB cooperate to regulate autophagy induction and lysosome biogenesis in response to starvation. Here we demonstrate that DNA damage activates TFE3 and TFEB in a p53 and mTORC1 dependent manner. RNA-Seq analysis of TFEB/TFE3 double-knockout cells exposed to etoposide reveals a profound dysregulation of the DNA damage response, including upstream regulators and downstream p53 targets.

Are Increased Masticatory Forces Risk for Primary 2nd Molars without Successors? A 3D FEA Study.

J Clin Pediatr Dent 2018 Dec 6. Epub 2018 Dec 6.

Objective: Persistent primary teeth with healthy crown-root structures and acceptable functional and esthetic properties may be preserved over a long-term period if needed. However, they may experience root resorption, ankylosis or infraocclusion especially in the second or third decades of life. Despite a lack of sufficient detailed data, increases in occlusal forces by age are known to cause destructive stresses on root surfaces and periodontal tissue. Read More
