Uptake and persistence of bacterial magnetite magnetosomes in a mammalian cell line: Implications for medical and biotechnological applications
(PUBLIC LIBRARY SCIENCE, 2019)Magnetotactic bacteria biomineralize intracellular magnetic nanocrystals surrounded by a lipid bilayer called magnetosomes. Due to their unique characteristics, magnetite magnetosomes are promising tools in Biomedicine. ... -
Mental illness, drinking, and the social division and structure of labor in the United States: 2003-2015
(WILEY, 2019)Background We draw on a relational theoretical perspective to investigate how the social division and structure of labor are associated with serious and moderate mental illness and binge and heavy drinking. Methods The ... -
Factors associated with objectively measured total sedentary time and screen time in children aged 9-11 years
(SOC BRASIL PEDIATRIA, 2019)Objective: To identify factors associated with total sedentary time and screen time in children aged 9-11 years. Methods: For seven consecutive days, 328 children (51.5% boys) used accelerometers to monitor total sedentary ... -
Repeated neonaticide: differences and similarities to single neonaticide events
(SPRINGER WIEN, 2019)This study aims to identify differences between single and repeat perpetrators of filicide by using register-based data. The study used register-based, comprehensive, nationwide data from both Austria and Finland. The ... -
The p75(NTR) neurotrophin receptor is required to organize the mature neuromuscular synapse by regulating synaptic vesicle availability
(BMC, 2019)The coordinated movement of organisms relies on efficient nerve-muscle communication at the neuromuscular junction. After peripheral nerve injury or neurodegeneration, motor neurons and Schwann cells increase the expression ... -
Complex I and II are required for normal mitochondrial Ca2+ homeostasis
(ELSEVIER SCI LTD, 2019)Cytosolic calcium (Ca-c(2+)) entry into mitochondria is facilitated by the mitochondrial membrane potential (Delta Psi m), an electrochemical gradient generated by the electron transport chain (ETC). Is has been assumed ... -
The Combination of Physical Activity and Sedentary Behaviors Modifies the Genetic Predisposition to Obesity
(WILEY, 2019)Objective This study aimed to investigate whether the association between a validated genetic profile risk score for BMI (GPRS-BMI) (based on 93 single-nucleotide polymorphisms) and phenotypic obesity (BMI) was modified ... -
Nanohybrid sensor for simple, cheap, and sensitive electrochemical recognition and detection of methylglyoxal as chemical markers
(ELSEVIER SCIENCE SA, 2019)We successfully designed a nanohybrid sensor based on carboxyl-functionalized multi-walled carbon nanotubes (MWCNTs-COOH) co-functionalized with both carboxymethyl cellulose (CMC) and chitosan nanosphere (CSN) for a simple, ... -
webCEMiTool: Co-expression Modular Analysis Made Easy
(FRONTIERS MEDIA SA, 2019)Co-expression analysis has been widely used to elucidate the functional architecture of genes under different biological processes. Such analysis, however, requires substantial knowledge about programming languages and/or ... -
On sign-changeable interaction in FLRW cosmology
(SPRINGER, 2019)We investigate an interacting two-fluid model in a spatially flat Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe, when the energy transfer between these two dark components is produced by a factorizable nonlinear ... -
Association of physical inactivity with blood pressure and cardiovascular risk factors in Amerindian schoolchildren
(WILEY, 2019)Objectives There is a wealth of published data on blood pressure (BP) and physical activity in adults of European descent, but less information is available for Amerindian schoolchildren. The aim of this study was to ... -
Exploring the Effect of the Irradiation Time on Photosensitized Dendrimer-Based Nanoaggregates for Potential Applications in Light-Driven Water Photoreduction
(MDPI, 2019)Fourth generation polyamidoamine dendrimer (PAMAM, G4) modified with fluorescein units (F) at the periphery and Pt nanoparticles stabilized by L-ascorbate were prepared. These dendrimers modified with hydrophobic fluorescein ... -
Film Dressings Based on Hydrogels: Simultaneous and Sustained-Release of Bioactive Compounds with Wound Healing Properties
(MDPI, 2019)This research proposes the rational modeling, synthesis and evaluation of film dressing hydrogels based on polyvinyl alcohol crosslinked with 20 different kinds of dicarboxylic acids. These formulations would allow the ... -
A decentralized route to the origins of scaling in human language
(IOP PUBLISHING LTD, 2019)Zipf's law establishes that if the words of a (large) text are ordered by decreasing frequency, the frequency versus the rank decreases as a power law with exponent close to -1. Previous work has stressed that this statistical ... -
Original research Socio-demographic patterning of self-reported physical activity and sitting time in Latin American countries: findings from ELANS
(BMC, 2019)Background: Low levels of physical activity (PA) and prolonged sitting time (ST) increase the risk of non-communicable diseases and mortality, and can be influenced by socio-demographic characteristics. The aim of this ... -
Adaptation to milking agropastoralism in Chilean goat herders and nutritional benefit of lactase persistence
(WILEY, 2019)The genetic trait of lactase persistence (LP) evolved as an adaptation to milking pastoralism in the Old World and is a well-known example of positive natural selection in humans. However, the specific mechanisms conferring ... -
Novel and Convenient Synthesis of 2,7-Dialkyl-1,8-dihydro- as -indacenes
(GEORG THIEME VERLAG KG, 2019)A novel and convenient synthetic route towards dialkyl as -indacenes was achieved by alkylation of malonic esters with o -xylylene dibromide, to give the corresponding tetraester, and related diacid. The alkyl groups on ... -
