Anemia is a frequent and challenging complication of mycobacterial infections. We used a model of disseminated Mycobacterium avium infection in mice to investigate the mechanisms of mycobacteria-induced anemia. We found increased formation of RBC in the bone marrow and spleen of infected mice. Infection induced reticulocytosis and the premature egress of immature progenitors to the systemic circulation in an IFN-γ (IFNG)-dependent way. The newly formed RBC had reduced CD47 surface expression and ...

Prion (PrP) and amyloid-beta (Abeta) peptides are involved in the neuronal loss that occurs in Prion disorders (PrD) and Alzheimer's disease (AD), respectively, partially due to Ca(2+) dysregulation. Besides, the endoplasmic reticulum (ER) stress has an active role in the neurotoxic mechanisms that lead to these pathologies. Here, we analyzed whether the ER-mediated apoptotic pathway is involved in the toxic effect of synthetic PrP and Abeta peptides. In PrP106-126- and Abeta1-40-treated cortical neurons, ...

A unique feature of plant aspartic proteinase precursors is the presence of an internal domain, known as plant-specific insert, whose function is not completely understood. The three-dimensional structure of the plant-specific insert resembles that of saposin-like proteins, a group of lipid-binding proteins involved in a variety of physiological processes. Here we show that recombinant plant-specific insert is able to interact with phospholipid vesicles and to induce leakage of their contents in ...

ABSTRACT The establishment of mycobacterial infection is characterized by the formation of granulomas, which are well-organized aggregates of immune cells, namely, infected macrophages. The granuloma's main function is to constrain and prevent dissemination of the mycobacteria while focusing the immune response to a limited area. In some cases these lesions can grow progressively into large granulomas which can undergo central necrosis, thereby leading to their caseation. Macrophages are the most ...

Moyamoya é um termo japones que significa «aspecto esfumado». Este aspecto caracteriza os achados angiográficos em crianças ou adultos com doença cerebrovascular oclusiva crónica progressiva. A etiologia é desconhecida, tendo sido proposta urna base hereditária por haver maior incidencia em indivíduos com antigénios HLA semelhantes aos da Síndrome de Down e da Neurofibromatose de Von Recklinghausen. E uma doença frequente no Japão, mas rara na Europa. A chave do diagnóstico é a angiografia. O tratamento ...

Digitalization across a range of industry and service sectors is transforming the workplace and human resources. The adoption of disruptive technologies associated with the Fourth Industrial Revolution, also known as Industry 4.0, is reshaping the way people work, learn, lead, manage, recruit, and interact with each other. The aim of this study is to contribute to the theoretical development of human resource management (HRM) in the context of Industry 4.0, promoting directions for the sector and ...

Most antidepressant agents have the potential to cause liver injury, even at therapeutic doses. Nevertheless, drug-induced liver injury (DILI) from antidepressant agents is a rare event. There is no way to prevent idiopathic DILI, but the severity of the reaction may be minimized with prompt recognition and early withdrawal of the agent. We describe a rare case of a 63-year-old man presenting with acute liver failure after 3 months of trazodone and diazepam administration at normal therapeutic doses, ...

Sustainability must be seen as a global issue. In order to achieve that goal, it is necessary to apply its principles to all industrial activities, including those that are not traditionally engaged with such guidelines, which is the case of Bridge Construction. This paper evaluates the consumption of steel and energy and the emissions of carbon dioxide due to the use of movable scaffolding systems (MSS) in the Bridge Construction industry. The values obtained considering the use of conventional ...

ABSTRACT:In recent years, the fourth industrial revolution has attracted increasing attention around the world. However, efforts are still lacking to systematically review the state of the art of this new wave of industrial revolution. In the second decade of the 21st century, the rapid proliferation of technology and the intensification of global competition created a sense of urgency for governments of developed and developing countries to engage in a major industrial revitalization, leading to ...

Fiber Bragg gratings (FBGs) have previously found many applications as strain and vibration sensors. Here we demonstrate that they may also be employed as pickups for musical instruments and, specifically, for acoustic guitars and solid-body electric guitars. By fixing the FBG to a vibrating part of the instrument's body, e.g., near the bridge of an acoustic guitar or on the headstock of a solid-body guitar, a number of sound recordings were made and compared to those obtained with either piezoelectric ...

Pt(0)-catalyzed ring-opening precipitation copolymerization of [1]silaferrocenophanes fcSiMe(2) (3) and the spirocyclic cross-linker fcSi(CH(2))(3) (4) (fc = Fe(eta(5)-C(5)H(4))(2)) was used to prepare polyferrocenylsilane microspheres (PFSMSs) under mild conditions. By varying the reaction conditions, a wide variety of other morphologies was obtained. The effects of temperature, monomer ratio, solvent composition, catalyst concentration, and time on the observed morphology were investigated and interpreted ...

Polyferrocenylsilane microspheres are readily formed under mild reaction conditions. Chemical oxidation leads to positively charged particles that undergo electrostatic self-assembly with smaller negatively charged silica microspheres, which leads to composite superstructures (see Figure), whereas pyrolysis leads to spherical magnetic ceramics that self-organize into two-dimensional arrays in a magnetic field.

The aim of this study was to quantify the type of offensive sequences that result in goals in elite futsal. Thirty competitive games in the Spanish Primera Division de Sala were analysed using computerised notation analysis for patterns of play that resulted in goals. More goals were scored in positional attack (42%) and from set pieces (27%) compared to other activities. The number of defence to offense "transitions" (n = 45) and the start of offensive plays due to the rules of the game (n = 45) were the ...

The purpose of this paper is to provide an overview of coaching and coaching education in Portugal. In Portugal, sport coaching is traditionally considered a part-time vocation. There has been a growing concern of the Portuguese authorities to increase the standards of quality for sport coaching. Following the 1974 revolution there were profound alterations in how coaching and coach education are regulated. The legislative changes in coach education occurred mainly due to the harmonisation of the ...

Novel poly(methylphenylsilane)−poly(ferrocenyldimethylsilane) copolymers 5a−d of varying monomer composition were prepared via the thermal ring-opening polymerization of a mixture of the strained cyclic tetrasilane [MePhSi]4 (1) and the silicon-bridged [1]ferrocenophane Fe(η-C5H4)2SiMe2 (3). The resulting materials were structurally characterized by 1H and 29Si NMR and also by gel permeation chromatography (GPC), pyrolysis mass spectrometry (MS), and cyclic voltammetry. GPC in THF indicated that the molecular ...

Transition metal (PtII or Pt0) catalyzed ring-opening polymerization (ROP) of silicon-bridged [1]ferrocenophanes has been found to permit simple and convenient control of the regiostructure, molecular weight, and architecture of poly(ferrocenes). Whereas thermal ROP of the unsymmetrical silicon-bridged [1]ferrocenophane Fe(η-C5H4)(η-C5Me4)SiMe2 (3) at 150 °C proceeds via a nonselective cleavage of the Si−CpH and Si−CpMe bonds (CpH = η-C5H4, CpMe = η-C5Me4) to yield an amorphous, regioirregular poly(ferrocenylsilane), ...

Strategies for preparing graft copolymers from brominated poly(isobutylene-co-isoprene) (BIIR) are demonstrated. Selective dehydrohalogenation of the allylic bromide functionality within BIIR to give an exo-conjugated diene is described, along with subsequent cycloadditions of maleic anhydride (MAn) and its mono-ester and di-ester derivatives. Alcoholysis of the bicyclic anhydride product of BIIR dehydrobromination/MAn cycloaddition is used to produce an IIR-g-PE copolymer in low yield. An alternate ...

The growing competitiveness of modern sport means that children, from very early ages, are increasingly submitted to intensive training programmes.

Using data collected through semi-structured interviews this study examines the various kinds of abuse ...
