CLEASE: A versatile and user-friendly implementation of Cluster Expansion method.

J Phys Condens Matter 2019 Apr 23. Epub 2019 Apr 23.

Department of Energy Conversion and Storage, Danmarks Tekniske Universitet, Fysikvej, Building 309, Lyngby, 2800, DENMARK.

Materials exhibiting a substitutional disorder such as multicomponent alloys and mixed metal oxides/oxyfluorides are of great importance in many scientific and technological sectors. Disordered materials constitute an overwhelmingly large configurational space, which makes it practically impossible to be explored manually using first-principles calculations such as density functional theory (DFT) due to the high computational costs. Consequently, the use of methods such as cluster expansion (CE) is vital in enhancing our understanding of the disordered materials. Read More

Res Pract Thromb Haemost 2019 Apr 4;3(2):161-172. Epub 2019 Mar 4.

Department of Pathology and Laboratory Medicine University of North Carolina Chapel Hill North Carolina.

Since its discovery over 350 years ago, studies of fibrinogen have revealed remarkable characteristics. Its complex structure as a large (340 kDa) hexameric homodimer supports complex roles in hemostasis and homeostasis. Fibrinogen synthesis is regulated at the transcriptional and translational levels, undergoing both constitutive (basal) secretion from liver, and inducible upregulation in response to inflammatory events.

Optimization of the photodynamic inactivation of prions by a phthalocyanine photosensitizer: the crucial involvement of singlet oxygen.

J Biophotonics 2019 Apr 15:e201800340. Epub 2019 Apr 15.

Institute of Immunology and Microbiology, First Faculty of Medicine, Charles University and General University Hospital in Prague, Prague 2, Czech Republic.

Prion disorders are fatal neurodegenerative diseases caused by the autocatalytic conversion of a natively occurring prion protein (PrP ) into its misfolded infectious form (PrP ). The proven resistance of PrP to common disinfection procedures increases the risk of prion transmission in medical settings. Herein, we present the effective photodynamic inactivation (PDI) of prions by disulfonated hydroxyaluminum phthalocyanine (AlPcOH(SO ) ) utilizing two custom-built red light sources. Read More

Elevated peripheral kynurenine/tryptophan ratio predicts poor short-term auditory memory in panic disorder patients.

J Psychiatr Res 2019 Apr 2;113:159-164. Epub 2019 Apr 2.

Laboratory of Panic & Respiration, Institute of Psychiatry, Federal University of Rio de Janeiro, Rua Ataulfo de Paiva 135 S. 609, 22440-901, Brazil.

Abnormalities in the kynurenine pathway (KP) have been implicated in the cognitive deficits of psychiatry disorders, possibly through cytokines that increase the activity of indoleamine-2,3 dioxygenase (IDO), a key enzyme for tryptophan-to-kynurenine conversion. Some studies on panic disorder (PD) have detected elevated cytokines in blood. We aimed to determine the extent to which elevated peripheral cytokine levels and kynurenine/tryptophan (kyn/tryp) ratio (1) are biological markers for PD patients and (2) are related to cognition in PD.

The truth about cognitive impairment in functional motor symptoms: An experimental deception study with the Guilty Knowledge Task.

J Clin Neurosci 2019 Mar 30. Epub 2019 Mar 30.

Dipartimento di Scienze della Salute, Universita degli Studi di Milano, Milano, Italy; Unità di Psichiatria, ASST Santi Paolo e Carlo, Milano, Italy; "Aldo Ravelli" Research Center for Neurotechnology and Experimental Brain Therapeutics, University of Milan, Italy.

Background: A century ago, Janet was the first to conceptualize conversion reactions as having a neurocognitive component, as disorders of memory processing that arise in the wake of trauma. The available evidence suggests that this impairment might arise from dysfunction in the fronto-subcortical circuits. Our aim was to examine the cognitive functions regulating deception in patients with functional motor symptoms (FMS), using a computerised task, the Guilty Knowledge Task (GKT). Read More

Characterization of the Safety and Pharmacokinetic Profile of D-Methadone, a Novel N-Methyl-D-Aspartate Receptor Antagonist in Healthy, Opioid-Naive Subjects: Results of Two Phase 1 Studies.

J Clin Psychopharmacol 2019 May/Jun;39(3):226-237

Relmada Therapeutics, Inc, New York, NY.

Purpose/background: N-methyl-D-aspartate (NMDA) receptor (NMDAR) antagonists are potential agents for the treatment of several central nervous system disorders including major depressive disorder. Racemic methadone, L-methadone, and D-methadone all bind the NMDAR with an affinity similar to that of established NMDAR antagonists, whereas only L-methadone and racemic methadone bind to opioid receptors with high affinity. Therefore, D-methadone is expected to have no clinically significant opioid effects at therapeutic doses mediated by its NMDAR antagonism. Read More

Generation of neural stem cells from adult astrocytes by using a single reprogramming factor.

J Cell Physiol 2019 Mar 25. Epub 2019 Mar 25.

Department of Stem Cells and Developmental Biology, Cell Science Research Center, Royan Institute for Stem Cell Biology and Technology, ACECR, Tehran, Iran.

Generating neural stem cells (NSCs) from astroglia as an abundant cell type in the mammalian brain has a promising outlook to be used in cell-replacement therapy for treatment of neurodegenerative disorders and neuronal trauma. However, little is known about a single reprogramming factor that may lead to the generation of induced NSCs (iNSCs) from adult brain-derived astrocytes in the absence of extrinsic inductive signals. Here, we show that zinc-finger nuclear protein Zfp521 alone is sufficient for converting the adult mouse brain-derived astrocytes into iNSCs. Read More

D-2-hydroxyglutaric aciduria Type I (D-2-HGA Type I), a neurometabolic disorder with a broad clinical spectrum, is caused by recessive variants in the D2HGDH gene encoding D-2-hydroxyglutarate dehydrogenase (D-2-HGDH). We and others detected 42 potentially pathogenic variants in D2HGDH of which 31 were missense. We developed functional studies to investigate the effect of missense variants on D-2-HGDH catalytic activity. Read More

Parallel profiling of DNA methylation and hydroxymethylation highlights neuropathology-associated epigenetic variation in Alzheimer's disease.

Clin Epigenetics 2019 03 21;11(1):52. Epub 2019 Mar 21.

College of Medicine and Health, University of Exeter Medical School, Exeter University, RILD Building Level 4, Royal Devon and Exeter Hospital, Barrack Rd, Exeter, EX2 5DW, UK.

Background: Alzheimer's disease is a progressive neurodegenerative disorder that is hypothesized to involve epigenetic dysfunction. Previous studies of DNA modifications in Alzheimer's disease have been unable to distinguish between DNA methylation and DNA hydroxymethylation. DNA hydroxymethylation has been shown to be enriched in the human brain, although its role in Alzheimer's disease has not yet been fully explored. Read More

Apparent Mineralocorticoid Excess in the Pediatric Population: Report of a Novel Pathogenic Variant of the 11β-HSD2 Gene and Systematic Review of the Literature.

Pediatr Endocrinol Rev 2019 Mar;16(3):335-358

Division of Pediatric Endocrinology, Baystate Children's Hopsital, USA.

Apparent mineralocorticoid excess (AME) is a rare inherited disorder caused by pathogenic variants in the 11β-HSD2 gene resulting in a deficiency of the 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) enzyme catalyzing the conversion of cortisol to its inactive metabolite, cortisone. Impaired cortisol metabolism results in a mineralocorticoid excess-like state presenting as low renin, low aldosterone hypertension (HTN) and hypokalemia. Typically, AME is diagnosed in early childhood. Read More

Continuously Enhanced Structural Disorder To Suppress the Lattice Thermal Conductivity of ZrNiSn-Based Half-Heusler Alloys by Multielement and Multisite Alloying with Very Low Hf Content.

ACS Appl Mater Interfaces 2019 Apr 26;11(14):13397-13404. Epub 2019 Mar 26.

State Key Laboratory of Silicon Materials and School of Materials Science and Engineering , Zhejiang University , Hangzhou 310027 , P. R. China.

ZrNiSn-based half-Heusler (HH) alloys are considered very promising thermoelectric (TE) materials at intermediate and high temperatures due to their favorable intrinsic electrical properties, but they are also limited by their inherent high thermal conductivities. Numerous works have focused on reducing their thermal conductivities, especially their lattice thermal conductivities. A multielement (Ti, Hf, Nb, V, and Sb) and multisite alloying strategy for simultaneously improving the electrical properties and greatly reducing the lattice thermal conductivity of ZrNiSn-based HH TE materials is reported in this work.

The Four-Cluster Spectrum of Mind-Body Interrelationships: An Integrative Model.

Front Psychiatry 2019 1;10:39. Epub 2019 Mar 1.

Psychology Department, Ben Gurion University of the Negev, Beersheba, Israel.

Despite the shift toward a biopsychosocial paradigm of medicine, many physicians and mental health professionals (MHPs) find it difficult to treat patients with psycho-somatic disorders. This situation is particularly troublesome due to the high prevalence of these conditions. Although progress has been made over the last few decades in understanding mechanisms underlying the mind-body relationship, disparities remain between research and its clinical implementation.

Fetal arrhythmias are common, and they may resolve spontaneously in majority of the cases. Sustained fetal arrhythmias associated with major structural heart disorders, hydrops fetalis, and fetal heart failure warrant intrauterine pharmaceutical conversion of heart rhythm or early pacemaker implant in order to avoid fetal demise. Fetal atrial flutter (AF) and supraventricular tachycardia (SVT) resemble in terms of the effects of intrauterine therapies. Read More

Mind the gaps: What we don't know about cognitive impairment in essential tremor.

Parkinsonism Relat Disord 2019 Mar 1. Epub 2019 Mar 1.

Department of Neurology, College of Physicians and Surgeons, Columbia University, New York, NY, USA; Taub Institute for Research on Alzheimer's Disease and the Aging Brain, College of Physicians and Surgeons, Columbia University, New York, NY, USA.

Introduction: Although the hallmark feature of essential tremor (ET) is tremor, there is growing appreciation that cognitive impairment also occurs, including increased prevalence of mild cognitive impairment (MCI) and increased prevalence and incidence of dementia. With emerging knowledge of ET-cognitive impairment, come fundamental questions regarding its course, bases, predictors and clinical outcomes. Studies in the general population and in Parkinson's disease (PD), a related movement disorder, offer a starting point from which to begin filling these clinically important knowledge gaps.

Enhanced laser crystallization of thin film amorphous molybdenum disulfide (MoS) by means of pulsed laser ultrasound.

Opt Express 2019 Feb;27(4):5859-5873

Experimental evidence is presented that pulsed laser generated ultrasound can reduce the power necessary to phase convert a nm-scale amorphous film into the crystalline phase. The amount of energy carried by pulsed ultrasound is scant when compared to the CW laser power used to crystallize but the effect is substantial. The evidence points to the extra-ordinary effects possible when a small energy perturbation is applied at a critical juncture in dynamical systems. Read More

Department of Synthetic Chemistry and Biological Chemistry, Graduate School of Engineering, Kyoto University, Katsura, Nishikyo-ku, Kyoto 615-8510, Japan. Electronic address:

Proteins as causative agents of diseases such as cancers, diabetes and neurological disorders are attractive drug targets. For developing chemicals selectively acting on key disease-causing proteins, one useful concept is the direct conversion of such target proteins into biosensors. This approach provides ligand-binding assay systems based on protein-based biosensors, which can quantitatively evaluate interactions between the protein and a specific ligand in many environments.

Seeing again: treatment of functional visual loss.

Pract Neurol 2019 Apr;19(2):168-172

Centre for Clinical Brain Sciences, University of Edinburgh, Western General Hospital, Edinburgh, UK

There is very little published literature on treatment strategies for functional visual loss. We present two people with long duration of functional visual loss who achieved complete recovery with a novel combination of therapeutic approaches. These included: (1) the clinician being transparent regarding positive signs such as optokinetic nystagmus, in order to persuade family members of the diagnosis, (2) regularly positively acknowledging everyday events that indicated visual ability, (3) using occipital transcranial magnetic stimulation to induce phosphenes as an artificial temporary visual experience and (4) using hypnotherapy to promote visual recovery.

Alterations in facial expressivity in youth at clinical high-risk for psychosis.

J Abnorm Psychol 2019 Mar 14. Epub 2019 Mar 14.

Department of Psychology, Northwestern University.

Negative symptoms, such as blunted facial affect, are core features of psychotic disorders that predict poor functional outcome. However, it is unknown whether these impairments occur prior to the onset of psychosis. Understanding this phenomenon in the psychosis risk period has significant relevance for elucidating pathogenic processes, as well as potential for informing a viable new behavioral marker for broader social dysfunction and clinical course.
