BACKGROUND: Methotrexate (MTX) is the first-line drug in the treatment of rheumatoid arthritis (RA) and the most commonly prescribed disease modifying anti-rheumatic drug. Moreover, it is also used as an adjuvant drug in patients under biologic therapies, enhancing the efficacy of biologic agents. OBJECTIVES: To review the literature and update the Portuguese recommendations for the use of MTX in rheumatic diseases first published in 2009. METHODS: The first Portuguese guidelines for the use of MTX in rheumatic diseases were published in 2009 and were integrated in the multinational 3E Initiative (Evidence Expertise Exchange) project...

Coupled plasma filtration and adsorption (CPFA) is a detoxification system that combines a plasma adsorption circuit and a continuous renal replacement therapy circuit. Its main application is for sepsis and septic shock with or without acute renal failure. Several recent studies have suggested that CPFA can reduce the mortality when the volume of plasma absorbed on the styrenic resin is at least >0.18 L/kg/day. At present, new applications for CPFA are under investigation, also in patients without significant kidney failure...

Dilovasi is one of the heavily industrialized areas in Turkey with serious environmental problems. In this study, the atmospheric concentration of PAHs and PCBs were measured for a whole year at 23 sites. The average ambient air Σ15PAH and Σ41PCB concentrations were found as 285 ± 431 ng m(-3) and 4152 ± 6072 pg m(-3), respectively. PAH concentrations increased with decreasing temperature especially in urban areas, indicating the impact of residential heating. However, PCB concentrations mostly increased with temperature probably due to enhanced volatilization from their sources...

In this study, passive detectors for Pb were prepared by immobilizing powdered rock phosphate in agarose beads. Rock phosphate has been used to treat Pb-contaminated waters and soil by fixing the metal as an insoluble pyromorphite mineral. Under lab conditions, Pb was rapidly adsorbed from aqueous solution by the beads over time, consistent with the acidic dissolution of rock phosphate, the precipitation of pyromorphite within the pore space of the agarose gel matrix, and surface exchange reactions. Net accumulation of Pb occurred when beads were exposed to simulated periodic releases of Pb over time...

Sulfonated holey graphene oxides (SHGOs) have synthesized by the etching of sulfonated graphene oxides with concentrated HNO3 under the assistance of ultrasonication. These SHGOs could be used as the fillers for the sulfonated aromatic poly(ether ether ketone) (SPEEK) membrane. The obtained SHGO incorporated SPEEK membrane has a uniform and dense structure, exhibiting the higher performance as proton exchange membranes (PEMs), for instance, higher proton conductivity, lower activation energy for proton conduction, and comparable methanol permeability, as compared to Nafion® 112...

Leptin and hypoxia are pro-fibrotic factors involved in fibrogenesis, however, the gene expression profiles remain to be fully elucidated. The aim of the present study was to investigate the regulatory roles of leptin and hypoxia on the L929 mouse fibroblast cell line. The cells were assigned to a normoxia, normoxia with leptin, hypoxia, and hypoxia with leptin group. The cDNA expression was detected using an Agilent mRNA array platform. The differentially expressed genes (DEGs) in response to leptin and hypoxia were identified using reverse transcription‑quantitative polymerase chain reaction analysis, followed by clustering analysis, Gene Ontology analysis and pathway analysis...

A decrease in bronchial diameter is designated as bronchoconstriction (BC) and impedes the flow of air through the airway. Asthma is characterized by inflammation of the airways, reversible BC and nonspecific hyperreactivity. These last two symptoms are dependent on airway smooth muscle. Stimuli that trigger contraction can be characterized as chemical (neurotransmitters, cytokines and terpenoids) and physical (volume inspired, air pressure). Both stimuli activate signaling pathways by acting on membrane proteins and facilitating the passage of ions through the membrane, generating a voltage change and a subsequent depolarization...

Uniform and conformal deposition of tin oxide thin films is important for several applications in electronics, gas sensing and transparent conducting electrodes. Thermal Atomic layer deposition (ALD) is often best suited for these applications, but its implementation requires a mechanistic understanding of the initial nucleation and subsequent ALD processes. To this end, in-situ FTIR and ex-situ XPS have been used to explore the ALD of tin oxide films using tributyltin ethoxide and ozone on an OH-terminated, SiO2-passivated Si(111) substrate...

Two dimensional (2D) homologous halide perovskites (HPs) microcrystallines have emerged as promising alternative light-sensitive materials, however, the undesirable quantum confinement effect and severe interfacial charge carrier scattering still hamper their applications in photodetectors (PDs). Here we propose a novel post-synthetic treatment to simultaneously solve both problems. 2D (OA)2FAn-1PbnBr3n+1 (OA and FA represent octadecylamine and formamidine) microplatelets film was immersed into solution containing FA+, leading to improvements in two aspects...

REVIEW

BACKGROUND: Currently, there are no concrete, evidence-based default procedures to adequately assess the capacity to consent to medical treatment. This explains why different raters use individual heuristics, differing both within and between disciplines. The lack of a procedure that is standardized, validated, and equally accepted across disciplines to assess the capacity to consent to treatment has led to an uncertainty in legal and medical practice regarding appropriate action and decision making...

This study will show the results of four dialogical cultural exchange classes, which were held between Japanese and Chinese high school students, and examine the shifts in students' viewpoints and changes in cultural understandings that occurred during those classes. In the first cultural exchange class, students of both countries read a story which described an older student who carelessly wore a T-shirt inside out, and younger students passed by without greeting him. Students of both countries were then asked to write their comments about it...

One new genus and three new species of Lygistorrhinidae in early Eocene Cambay amber from India are described, which significantly increases our knowledge about this group in the Eocene. Lygistorrhina indica n. sp. is the oldest fossil known from this extant genus. Indorrhina sahnii n. gen. et sp. shows morphological similarities to each of the two extant genera Lygistorrhina and Asiorrhina. Palaeognoriste orientale is the third species known from a group that has only been recorded from Eocene Baltic amber before...

REVIEW
David Sancho, Michel Enamorado, Johan Garaude
Sensing of microbe-associated molecular patterns or danger signals by innate immune receptors drives a complex exchange of information. Innate receptor signaling not only triggers transcriptional events but also induces profound changes in metabolic fluxes, redox balance, and metabolite abundance thereby influencing immune cell function. Mitochondria are at the core of metabolic adaptation to the changing environment. The close interaction between mitochondrial metabolism and immune signaling has emerged as a central regulator of innate sensing...

Orexins peptides exert a prominent role in arousal-related processes including stress responding, by activating orexin-1 (OX1R) and orexin-2 (OX2R) receptors located widely throughout the brain. Stress or orexin administration stimulates hyperarousal, adrenocorticotropic hormone (ACTH) and corticosterone release, and selective OX1R blockade can attenuate several stress-induced behavioral and cardiovascular responses but not the hypothalamic-pituitary-adrenal (HPA) axis activation. As opposed to OX1R, OX2R are preferentially expressed in the paraventricular hypothalamic nucleus which is involved in the HPA axis regulation...

BACKGROUND: The mechanism of hypoxic pulmonary vasoconstriction (HPV) is still debatable. It has been proposed that reactive oxygen species (ROS) might be involved in HPV. However, there is no special transporter for superoxide anion in the cell membrane and it may release from the cells via anion exchanger. Therefore, the aim of this study was to investigate the interaction of ROS and anion exchanger in acute HPV. METHODS: The present study was performed in the isolated rabbit lung...

The osteoinductive properties of prostaglandin E2 (PGE2) and its signaling pathways have led to suggestions that it may serve as a potential therapeutic strategy for bone loss. However, the prominence of PGE2 as an inducer of bone formation is attributed primarily to findings from studies using rodent models. In the current study, we investigated the effects of PGE2 on human bone marrow stromal cell (hBMSC) lineage commitment and determined its mode of action. We demonstrated that PGE2 treatment of hBMSCs significantly altered the expression profile of several genes associated with osteoblast differentiation (RUNX2 and ALP) and maturation (BGLAP and MGP)...
