Neuroimaging in Functional Movement Disorders.

Curr Neurol Neurosci Rep 2019 Feb 12;19(3):12. Epub 2019 Feb 12.

Neuroscience Research Centre, Institute of Molecular and Clinical Sciences, St George's University of London;, Cranmer Terrace, London, SW17 0QT, UK.

Purpose Of Review: Functional movement disorders are common and disabling causes of abnormal movement control. Here, we review the current state of the evidence on the use of neuroimaging in Functional movement disorders, particularly its role in helping to unravel the pathophysiology of this enigmatic condition.

Recent Findings: In recent years, there has been a shift in thinking about functional movement disorder, away from a focus on high-level psychological precipitants as in Freudian conversion theories, or even an implicit belief they are 'put-on' for secondary gain. Read More

Corn waste valorization to generate activated hydrochar to recover ammonium nitrogen from compost leachate by hydrothermal assisted pretreatment.

J Environ Manage 2019 Feb 1;236:108-117. Epub 2019 Feb 1.

Institute of Rural Energy and Environmental Protection, Chinese Academy of Agricultural Engineering, Beijing 100026, China.

Valorization of corn waste involves synthesis of hydrochar for use as a sorbent for ammonium nitrogen recovery from swine manure compost leachate. However, the inability to directly capture organic nitrogen and insoluble nitrogen, and the low sorption ability of hydrochar remain key issues. To overcome these issues, we used hydrothermal assisted pretreatment of compost leachate to promote the solubilization of nitrogen contained in feces, and the conversion of organic nitrogen into ammonium nitrogen in the compost leachate.

Progranulin Stimulates the In Vitro Maturation of Pro-Cathepsin D at Acidic pH.

J Mol Biol 2019 Jan 25. Epub 2019 Jan 25.

Department of Neurology, University of California, San Francisco, CA 94143, USA. Electronic address:

Single-copy loss-of-function mutations in the progranulin gene (PGRN) underlie the neurodegenerative disease frontotemporal lobar degeneration, while homozygous loss-of-function of PGRN results in the lysosomal storage disorder neuronal ceroid lipofuscinosis. Despite evidence that normal PGRN levels are critical for neuronal health, the function of this protein is not yet understood. Here, we show that PGRN stimulates the in vitro maturation of the lysosomal aspartyl protease cathepsin D (CTSD). Read More

Patient safety, cost-effectiveness, and quality of life: reduction of delirium risk and postoperative cognitive dysfunction after elective procedures in older adults-study protocol for a stepped-wedge cluster randomized trial (PAWEL Study).

Trials 2019 Jan 21;20(1):71. Epub 2019 Jan 21.

Department of Social and Preventive Medicine, University of Potsdam, Am Neuen Palais 10, 14469, Potsdam, Germany.

Background: Postoperative delirium is a common disorder in older adults that is associated with higher morbidity and mortality, prolonged cognitive impairment, development of dementia, higher institutionalization rates, and rising healthcare costs. The probability of delirium after surgery increases with patients' age, with pre-existing cognitive impairment, and with comorbidities, and its diagnosis and treatment is dependent on the knowledge of diagnostic criteria, risk factors, and treatment options of the medical staff. In this study, we will investigate whether a cross-sectoral and multimodal intervention for preventing delirium can reduce the prevalence of delirium and postoperative cognitive decline (POCD) in patients older than 70 years undergoing elective surgery.

Benefit-Risk Assessment of Plecanatide in the Treatment of Chronic Idiopathic Constipation.

Authors:
Philip B Miner

Drug Saf 2019 Jan 16. Epub 2019 Jan 16.

Oklahoma Foundation for Digestive Research, 1813 Coventry Lane, Oklahoma City, OK, 73120, USA.

Plecanatide, a uroguanylin analog, activates the guanylate cyclase C receptors in the epithelial lining of the gastrointestinal tract in a pH-dependent fashion initiating (1) the conversion of intracellular guanosine triphosphate to cyclic guanosine monophosphate, which increases the activity of the cystic fibrosis transmembrane conductance regulator to increase chloride and bicarbonate secretion into the intestinal lumen and (2) a decrease in activity of the sodium-hydrogen ion exchanger. The resulting ionic shifts cause an increase in lumenal fluid to facilitate digestion. Plecanatide has been approved by the FDA for use in chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation. Read More

Copper-Driven Deselenization: A Strategy for Selective Conversion of Copper Ion to Nanozyme and Its Implication for Copper-Related Disorders.

ACS Appl Mater Interfaces 2019 Feb 28;11(5):4766-4776. Epub 2019 Jan 28.

Synthetic organic molecules, which can selectively convert excess intracellular copper (Cu) ions to nanozymes with an ability to protect cells from oxidative stress, are highly significant in developing therapeutic agents against Cu-related disorder like Wilson's disease. Here, we report 1,3-bis(2-hydroxyethyl)-1 H-benzoimidazole-2-selenone (1), which shows a remarkable ability to remove Cu ion from glutathione, a major cytosolic Cu-binding ligand, and thereafter converts it into copper selenide (CuSe) nanozyme that exhibits remarkable glutathione peroxidase-like activity, at cellular level of HO concentration, with excellent cytoprotective effect against oxidative stress in hepatocyte. Cu-driven deselenization of 1, under physiologically relevant conditions, occurred in two steps. Read More

Electronic address:

Idiopathic rapid eye movement sleep behavior disorder (iRBD) is a parasomnia characterized by the loss of muscle atonia and the presence of undesirable motor manifestations during rapid eye movement sleep. Research findings have shown that iRBD is a prodromal stage of synucleinopathies such as Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy. A wide array of neuroimaging techniques have improved our understanding of the prodromal stage of these diseases in patients with iRBD, and identified potential biomarkers. Read More

Diluted Oxide Interfaces with Tunable Ground States.

Adv Mater 2019 Jan 13:e1805970. Epub 2019 Jan 13.

Department of Energy Conversion and Storage, Technical University of Denmark, Risø Campus, 4000, Roskilde, Denmark.

The metallic interface between two oxide insulators, such as LaAlO /SrTiO (LAO/STO), provides new opportunities for electronics and spintronics. However, due to the presence of multiple orbital populations, tailoring the interfacial properties such as the ground state and metal-insulator transitions remains challenging. Here, an unforeseen tunability of the phase diagram of LAO/STO is reported by alloying LAO with a ferromagnetic LaMnO insulator without forming lattice disorder and at the same time without changing the polarity of the system.

Ab initio thermodynamics of liquid and solid water.

Proc Natl Acad Sci U S A 2019 Jan 4;116(4):1110-1115. Epub 2019 Jan 4.

Laboratory of Computational Science and Modeling, Institute of Materials, École Polytechnique Fédérale de Lausanne, 1015 Lausanne, Switzerland.

Thermodynamic properties of liquid water as well as hexagonal (Ih) and cubic (Ic) ice are predicted based on density functional theory at the hybrid-functional level, rigorously taking into account quantum nuclear motion, anharmonic fluctuations, and proton disorder. This is made possible by combining advanced free-energy methods and state-of-the-art machine-learning techniques. The ab initio description leads to structural properties in excellent agreement with experiments and reliable estimates of the melting points of light and heavy water. Read More

Hidden energy levels? Carrier transport ability of CdS/CdSSe quantum dot solar cells impacted by Cd-Cd level formation.

Nanoscale 2019 Jan;11(2):762-774

Centro de Investigaciones en Catálisis (CICAT), Universidad Industrial de Santander, Sede UIS Guatiguará, Piedecuesta, Santander, C.P. 681011, Colombia.

In quantum dot sensitized solar cells (QDSSC), a cascade energy level structure controlled by assembly of cadmium-chalcogenide quantum dots can remarkably improve the sunlight harvesting and charge carrier lifetime. Despite the advantages of using co-sensitizers, energy conversion efficiencies are still low. An increased understanding of the causes of the low photoconversion efficiency (PCE) will contribute to the development of a straightforward approach to improve solar cell performance by exploiting co-sensitization.

Factor Analysis of Negative Symptom Items in the Structured Interview for Prodromal Syndromes.

Schizophr Bull 2018 Dec 8. Epub 2018 Dec 8.

Department of Psychology, Department of Psychiatry, Department of Medical Social Sciences, Institute for Policy Research, Institute for Innovations in Developmental Sciences, Northwestern University, Evanston, IL.

Background: Negative symptoms occur early in the clinical high risk (CHR) state and indicate increased risk of conversion to psychotic disorder and poor functional outcome. However, while the negative symptom domain has shown to be parsimoniously explained by a 2-factor construct in schizophrenia, there has yet to be an established factor structure of negative symptoms in CHR.

Methods: 214 individuals meeting the Structured Interview for Psychosis-Risk Syndromes (SIPS) criteria for CHR were recruited through 3 active research programs in the United States. Read More

Germ cell neoplasia in situ complicating 17β-hydroxysteroid dehydrogenase type 3 deficiency.

Mol Cell Endocrinol 2018 Nov 30. Epub 2018 Nov 30.

Division of Metabolism, Endocrinology, & Diabetes, Department of Internal Medicine, University of Michigan, Ann Arbor, MI, USA; Department of Pharmacology, University of Michigan, Ann Arbor, MI, USA.

17β-hydroxysteroid dehydrogenase type 3 (17βHSD3) deficiency is an autosomal recessive disorder of male sex development that results in defective testosterone biosynthesis. Although mutations in the cognate HSD17B3 gene cause a spectrum of phenotypic manifestations, the majority of affected patients are genetic males having female external genitalia. Many cases do not present until puberty, at which time peripheral conversion of androgen precursors causes progressive virilization. Read More

Pathogenic Variants in Fucokinase Cause a Congenital Disorder of Glycosylation.

Am J Hum Genet 2018 Dec 29;103(6):1030-1037. Epub 2018 Nov 29.

Human Genetics Program, Sanford-Burnham-Prebys Medical Discovery Institute, La Jolla, CA 92037, USA. Electronic address:

FUK encodes fucokinase, the only enzyme capable of converting L-fucose to fucose-1-phosphate, which will ultimately be used for synthesizing GDP-fucose, the donor substrate for all fucosyltransferases. Although it is essential for fucose salvage, this pathway is thought to make only a minor contribution to the total amount of GDP-fucose. A second pathway, the major de novo pathway, involves conversion of GDP-mannose to GDP-fucose. Read More

Department of Neurology, St. George's, University of London, London, United Kingdom. Electronic address:

Functional (psychogenic) gait disorders are a common presentation of functional neurological disorder - one of the commonest diagnoses made in neurology practice. People with functional neurological disorder are as disabled and experience as poor a quality of life as patients with multiple sclerosis and Parkinson's disease. People with functional neurological disorder, including gait disorder, are often perceived as being challenging to diagnose and manage, and as a result attitudes of health professionals towards them are often negative.
