Alcohol and marijuana use as daily predictors of suicide ideation and attempts among adolescents prior to psychiatric hospitalization
(ELSEVIER IRELAND LTD, 2019)Objective: Little research has been conducted on alcohol use, marijuana use, and suicide ideation and attempts on a daily level, and specifically among adolescents prior to inpatient hospitalization. The purpose of this ... -
Alcohol Consumption in Later Life and Mortality in the United States: Results from 9 Waves of the Health and Retirement Study
(WILEY, 2019)Background Alcohol consumption in later life has increased in the past decade, and the relationship between alcohol consumption and mortality is controversial. Recent studies suggest little, if any, health benefit to ... -
Alimentary necrobacillosis in alpacas
(SAGE PUBLICATIONS INC, 2020)Ulcers of the oral cavity, esophagus, and gastric compartments of South American camelids are uncommon. Multifocal-to-coalescing ulcers were identified in the oral cavity, esophagus, and/or gastric compartments of 5 alpacas ... -

ALS-linked protein disulfide isomerase variants cause motor dysfunction
(CIENCIAS, 2016)Disturbance of endoplasmic reticulum (ER) proteostasis is a common feature of amyotrophic lateral sclerosis (ALS). Protein disulfide isomerases (PDIs) are ER foldases identified as possible ALS biomarkers, as well as ... -
Alteraciones vasculares en síndrome del túnel carpiano severo: un diagnóstico diferencial de vasculitis
(Facultad de Ciencias, 2012)El síndrome del túnel carpiano puede manifestarse con lesiones cutáneas. Estas pueden plantear el diagnóstico diferencial con una vasculitis. El compromiso del sistema nervioso simpático perivascular y los traumatismos a ... -
Alterations in type i hemidesmosome components suggestive of epigenetic control in the salivary glands of patients with Sjogren's syndrome
(Facultad de Ciencias, 2011)Objective. Acinar cells in the salivary glands of patients with Sjo¨gren’s syndrome (SS) display severe alterations in anchorage to the basal lamina. Bioinformatics analysis of the BP230 gene sequence has revealed the ... -
Altered mitochondrial bioenergetics are responsible for the delay in Wallerian degeneration observed in neonatal mice
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2019)Neurodegenerative and neuromuscular disorders can manifest throughout the lifespan of an individual, from infant to elderly individuals. Axonal and synaptic degeneration are early and critical elements of nearly all human ... -
Altered potassium channel distribution and composition in myelinated axons suppresses hyperexcitability following injury
(CIENCIAS, 2016)Neuropathic pain following peripheral nerve injury is associated with hyperexcitability in damaged myelinated sensory axons, which begins to normalise over time. We investigated the composition and distribution of ... -
Amazonian trees show increased edge effects due to Atlantic Ocean warming and northward displacement of the Intertropical Convergence Zone since 1980
(ELSEVIER, 2019)Recent investigations indicate a warming of Atlantic Ocean surface waters since 1980, probably influenced by anthropic actions, inducing rainfall intensification mainly during the rainy season and slight reductions during ... -

An efficient semi-analytical method to compute displacements and stresses in an elastic half-space with a hemispherical pit
(CIENCIAS, 2015)This paper presents an efficient method to calculate the displacement and stress fields in an isotropic elastic half-space having a hemispherical pit and being subject to gravity. The method is semi-analytical and takes ... -
An eight to thirteen hertz cut-off low pass filter is more appropriate to treat isoinertial accelerometry signals during jumping
(Kowsar Publishing Company, 2018)Background: Advances in micro-electromechanical systems have made the massive use of isoinertial accelerometry units (IAU) possible in multiple fields. Particularly, in sport and sport-rehabilitation contexts, jumping is ... -
