Brain injury constitutes a disabling health condition of several etiologies. One of the major causes of brain injury is hypoxia-ischemia. Until recently, pharmacological treatments were solely focused on neurons. In the last decades, glial cells started to be considered as alternative targets for neuroprotection. Novel treatments for hypoxia-ischemia intend to modulate reactive forms of glial cells, and/or potentiate their recovery response. In this review, we summarize these neuroprotective strategies in hypoxia-ischemia and discuss their mechanisms of action...

Noonan syndrome (NS) is a common genetic syndrome associated with gain of function variants in genes in the Ras/MAPK pathway. The phenotype of NS has been well characterized in populations of European descent with less attention given to other groups. In this study, individuals from diverse populations with NS were evaluated clinically and by facial analysis technology. Clinical data and images from 125 individuals with NS were obtained from 20 countries with an average age of 8 years and female composition of 46%...

OBJECTIVE: To determine whether a transcranial magnetic stimulation (TMS) multiparadigm approach can be used to distinguish Alzheimer disease (AD) from frontotemporal dementia (FTD). METHODS: Paired-pulse TMS was used to investigate short-interval intracortical inhibition (SICI) and facilitation (ICF), long-interval intracortical inhibition, and short-latency afferent inhibition (SAI) to measure the activity of different intracortical circuits in patients with AD, patients with FTD, and healthy controls (HC)...

BACKGROUND: CUB and zona pellucida-like domain-containing protein 1 (CUZD1) was identified as a pancreas-specific protein and was proposed as a candidate biomarker for pancreatic related disorders. CUZD1 protein levels in tissues and biological fluids have not been extensively examined. The purpose of the present study was to generate specific antibodies targeting CUZD1 to assess CUZD1 expression within tissues and biological fluids. METHODS: Mouse monoclonal antibodies against CUZD1 were generated and used to perform immunohistochemical analyses and to develop a sensitive and specific enzyme-linked immunosorbent assay (ELISA)...

Targeting mitochondrial oxidative stress is an effective therapeutic strategy. In this context, a rational design of mitochondriotropic antioxidants (compounds 22 to 27) based on a dietary antioxidant (caffeic acid) was performed. Jointly named as AntiOxCINs, these molecules take advantage of the known ability of the triphenylphosphonium cation to target active molecules to mitochondria. The study was guided by structure-activity-toxicity-property relationships and we demonstrate in this work that the novel AntiOxCINs act as mitochondriotropic antioxidants...

AIM: To optimize the production of pH-sensitive dapsone (DAP) nanoparticles based on Eugradit L100 (NPs-EL100-DAP) for oral delivery. MATERIALS & METHODS: NPs-EL100-DAP were optimized using a Plackett-Burman design and a Box-Behnken design. The physicochemical properties of the obtained nanoparticles were monitored by microscopy, dynamic light scattering, Fourier transform infrared spectroscopy, differential scanning calorimetry, in vitro release assays, and examined for cytotoxicity and permeation across intestinal barrier...

HIV and M. tuberculosis are two intersecting epidemics making the search for new dual action drugs against both pathogens extremely important. Here, we report on the synthesis and suppressive activities of five dual-targeted HIV/TB compounds. These compounds constitute heterodimers of AZT, as anti-HIV molecules, and 5-arylaminouracil derivatives or 2'-deoxyuridine monophosphates analogues, as anti-TB molecules. We found that these compounds inhibit the growth of M. tuberculosis and suppress the replication of HIV in human cell cultures and human lymphoid tissues ex vivo...

The purpose of this review is to summarize the key findings which prove that the biased perceptions of viewers may provide an inaccurate image of the informational validity of televised news. The news may generate distorted recollections of what occurred in particular reported events if displayed routines influence viewers not to pay attention to the essential features of a narrative. Elaborating on Fiske and Hartley (2010), Zelizer (2010), and Gunter (2015), we indicate that the character of the news setting has altered and individuals' news consumption routines have changed in adapting to media advancements...

Hyperoxaluria can result in oxalate nephropathy with intratubular calcium oxalate crystallization and acute tubular injury. Primary inherited enzymatic deficiency or secondary causes such as excessive dietary intake, enteric increased absorption, or high doses of vitamin C, which is metabolized to oxalate, may underlie hyperoxaluria and oxalate nephropathy. We report a case of acute kidney injury due to oxalate nephropathy in a patient using chelating therapy with oral ethylenediamine tetra acetic acid (EDTA), intravenous supplementation with vitamin C, and chronic diarrhea and discuss the potential kidney damage these factors can cause in particular settings...

Semiconductor quantum dots (QDs) have demonstrated a great potential as fluorescent probes for heavy metals monitoring. However, their great reactivity, whose tunability could be difficult to attain, could impair selectivity yielding analytical results with poor accuracy. In this work, the combination in the same analysis of multiple QDs, each with a particular ability to interact with the analyte, assured a multi-point detection that was not only exploited for a more precise analyte discrimination but also for the simultaneous discrimination of multiple mutually interfering species, in the same sample...

The aim of this study was to characterize Streptococcus pneumoniae serotype 19A isolates causing invasive pneumococcal disease in children, collected in Argentina between 1993 and 2014. A total of 176 isolates serotype 19A were analyzed. There was an increase in the proportion of serotype 19A isolates from 3% in 1993 to 6% in 2011, prior to the introduction of PCV13 in 2012, and from 2012 to 2014 its proportion gradually decreased. Penicillin resistance among serotype 19A isolates throughout the study period was 65...

Several studies have observed that a conventional PCR protocol using primers LM1 and LM2 for the identification of gene hlyA Listeria monocytogenes generates non-specific PCR amplifications and false positives. For this reason in this study, we provide a modified PCR protocol that improves the specificity of the LM1 and LM2 primers.

As a case study, the estuary of the international Douro River (Iberian Peninsula) was sampled over a year (2010) at six sampling sites to determine the presence of 56 pesticides of different categories (insecticides, herbicides, and fungicides). 96% of measured pesticides were detected in 79% of the quantified samples. Individual average pesticide concentrations ranged from 39 to 1 265ng/L, indicating a ubiquitous presence of the selected compounds; moreover, twelve pesticides were above the 2013/39/EU Directive limits...

BACKGROUND: Many reviews aim to compare numerous treatments and report results stratified by subgroups (e.g. by disease severity). In such cases, a network meta-analysis model including treatment by covariate interactions can estimate the relative effects of all treatment pairings for each subgroup of patients. Two key assumptions underlie such models, consistency of treatment effects and consistency of the regression coefficients for the interactions. Consistency may differ depending on the covariate value at which consistency is assessed...

AIM: The aim of the present study was to assess the cost, acceptability and affordability of the healthy food basket (HFB) among low-income families in Cyprus. METHODS: HFBs were constructed based on the National Guidelines for Nutrition and Exercise for six different types of households. Acceptability was tested through focus groups. Affordability was defined as the cost of the HFB as a percentage of the guaranteed minimum income (GMI). The value of the GMI is set to be equal to €480 for a single individual and increases with the size of the recipient unit in accordance with the Organization for Economic Co-operation and Development equivalence scales...

The RNA-binding protein HuR promotes tumor growth by affecting proliferation, metastasis, apoptosis, and angiogenesis. Although immune cells, especially tumor-associated macrophages, are critical components of the tumor stroma, the influence of HuR in tumors on the recruitment of immune cells remains poorly understood. In the present study, we therefore aimed to elucidate the impact of tumor cell HuR on the interaction between tumor cells and macrophages. To this end, we stably depleted HuR in human MCF-7 breast cancer cells...
