Mesoporous silica features open and accessible pores that can intake substances from the outside. The combination of mesoporous silica with plasmonic nanostructures represents an interesting platform for an optical sensor based on the dependence of plasmonic modes on the refractive index of the medium in which metallic nanoparticles are embedded. However, so far only a limited number of plasmonic nanostructures are combined with mesoporous silica, including random dispersion of metallic nanoparticles and flat metallic thin films.

The aim of this study was to evaluate the effectiveness and safety of a multidisciplinary early proactive TDM (mep-TDM) programme for dose adjustment.
Methods: A 3-year prospective study was conducted based on a sample of 81 patients who started treatment and were subsequently subjected to mep-TDM with the first control at week 14.

Home hospitalization (HH) is presented as a healthcare alternative capable of providing high standards of care when patients no longer need hospital facilities. Although HH seems to lower healthcare costs by shortening hospital stays and improving patient's quality of life, the lack of continuous observation at home may lead to complications in some patients. Since blood tests have been proven to provide relevant prognosis information in many diseases, this paper analyzes the impact of different sampling methods on the prediction of HH outcomes.

In this study, hydrolysates of bovine lactoferrin (bLFH) obtained with pepsin, chymosin and microbial rennet were assayed against Cronobacter sakazakii (10 CFU/mL) in different media: phosphate buffered saline (PBS), bovine skim milk and whey, and reconstituted powdered infant formula (PIFM). The results obtained have shown that hydrolysis of bLF enhances its antibacterial activity against C.

Clostridium tyrobutyricum is the major agent that causes the blowing defect in cheese due to the germination of its dormant spores during the ripening stage. As a result, many of the affected cheeses show cavities and cracks, which cause the product loss in most cases. Nowadays, there is not a fast method capable of detecting milk contaminated with C.

Material And Methods: We retrospectively analyzed cardiac MRI studies done in 120 patients (mean age, 67±11.6 years; 88 men) with suspected ischemic heart disease or known coronary disease who had clinical indications for cardiac MRI stress tests.
The majority of research on the judgment of emotion from facial expressions has focused on deliberately posed displays, often sampled from single stimulus sets. Herein, we investigate emotion recognition from posed and spontaneous expressions, comparing classification performance between humans and machine in a cross-corpora investigation. For this, dynamic facial stimuli portraying the six basic emotions were sampled from a broad range of different databases, and then presented to human observers and a machine classifier.

Given the high evolutionary conservation of pain, investigative approaches from Drosophila mutagenesis to human Mendelian genetics have aided our understanding of the maladaptive plasticity underlying NeuP. Successes include the identification of ion channel variants causing hyper-excitability and the importance of neuro-immune signaling.

Methods: document analysis and literature review followed by a consensus workshop with specialists, 19 specialists were invited who were selected because of their teaching or research experience, professional activities or publications related to the subject; validation took place on an online platform where participants were asked to analyze the evaluation proposal and to give their opinion based on the categories 'I totally agree', 'partially agree', and 'disagree'.
Results: 15 specialists confirmed their participation; at the end of three rounds, the specialists emphasized the clarity of the proposal and the clarity of the object of evaluation presented in both the Logic Model and the Theoretical Logic Model; the specialists fully agreed with the Evaluation Matrix and confirmed its theoretical consistency.
Efficient and versatile spin-to-charge current conversion is crucial for the development of spintronic applications, which strongly rely on the ability to electrically generate and detect spin currents. In this context, the spin Hall effect has been widely studied in heavy metals with strong spin-orbit coupling. While the high crystal symmetry in these materials limits the conversion to the orthogonal configuration, unusual configurations are expected in low-symmetry transition-metal dichalcogenide semimetals, which could add flexibility to the electrical injection and detection of pure spin currents.

Methods: This was an ECCO-CONFER project.
Objective: to describe updating of stratification of the Brazilian municipalities in order to evaluate health performance.
Methods: this was a descriptive and methodological study with stratification of municipalities according to population size and conditions influencing health management, using data from the intercensal period (2015) and showing classification variations compared with the census period (2010); the original data on demographic characteristics, funding capacity and population purchasing power were adjusted for the year 2015 based on a baseline study conducted with census data.
Results: some 15% of the municipalities were reclassified in the intercensal period, with the main factors of change being the conditions influencing health management.
Mitochondria are dynamic organelles that in most cells behave as a dynamic network and can change their biogenesis and structure depending on the cell needs or as a response to different conditions. Analyzing the architecture of mitochondria is determinant to describe their state and function. In this chapter, image processing techniques are applied in a workflow manner to segment the mitochondrial network and extract the most relevant parameters that enable an accurate morphology analysis.

Background: Thiopurines are the most widely used immunosuppressants in IBD although drug-related adverse events (AE) occur in 20%-30% of cases.
Aim: To evaluate the safety of thiopurines in elderly IBD patients METHODS: Cohort study including all adult patients in the ENEIDA registry who received thiopurines. Patients were grouped in terms of age at the beginning of thiopurine treatment, specifically in those who started thiopurines over 60 years or between 18 and 50 years of age.
Background: Dementia-related neuropsychiatric symptoms (NPS) are the main determinant of family stress and institutionalization of patients. This study aimed to identify inequalities by gender and socioeconomic status in the management of NPS in patients diagnosed with dementia.

A major step in mucin 2 assembly is further multimerization of preformed mucin dimers, thought to produce a honeycomb-like arrangement upon hydrogel expansion. Important open questions are how multiple mucin 2 dimers become covalently linked to one another and how mucin 2 multimerization compares with analogous processes in related polymers such as respiratory tract mucins and the hemostasis protein von Willebrand factor.
