Alejandro Serani Merlo
There is actually a pervasive tendency to consider environmental ethics and bioethics as specific cases pertaining to a supposed kind of ″applied ethics″. Application can be understood in two different meanings: a concrete sense, as in technical applications, and a psychological meaning, as when we mentally apply ourselves to a task. Ethics has been always thought as a practical knowledge, in a ″praxical″ sense and not in a ″poietic″ one. Ethics has to do with ″ends″ not with ″means″; in this sense ethics is ″useless″...

In this work, the development of a new crystallization technique is reported, using nitrogen plasma (AC) to obtain nanostructured anatase and rutile from amorphous titanium oxide (TiO2). This methodology increases throughput and minimizes thermal effects. Nanostructured amorphous TiO2 was obtained by the sol-gel method and subsequently subjected to AC treatment, at a controlled pressure, applying different powers and treatment times in order to obtain phase changes. The obtained samples were characterized using X-ray diffraction (XRD), thermogravimetric analysis (TGA), and X-ray photoelectron spectroscopy (XPS)...

Malaria remains a major public health problem in the Peruvian Amazon where the persistence of high-risk transmission areas (hotspots) challenges the current malaria control strategies. This study aimed at identifying significant space-time clusters of malaria incidence in Loreto region 2002-2013 and to determine significant changes across years in relation to the control measures applied. Poisson regression and purely temporal, spatial, and space-time analyses were conducted. Three significantly different periods in terms of annual incidence rates (AIR) were identified, overlapping respectively with the pre-, during, and post- implementation control activities supported by PAMAFRO project...

INTRODUCTION: The incidence of obesity has increased significantly worldwide. Our hypothesis was that patients with obesity have a more severe distal radius fracture andwe realized a study to evaluate this correlation between obesity and severity of distal radius fractures caused by low-energy injuries. MATERIALS AND METHODS: A total of 114 patients with distal radius fracture were examined in a cross-sectional, observational study. Fractures were classified according to the international AO-Müller/Orthopedic Trauma Association (AO/OTA) classification in order to determine the severity...

Diverse chromatin modifiers are involved in regulation of gene expression at the level of transcriptional regulation. Among these modifiers are ATP-dependent chromatin remodelers, where the SWI/SNF complex is the founding member. It has been observed that High Mobility Group (HMG) proteins can influence the activity of a number of these chromatin remodelers. In this context, we have previously demonstrated that the yeast HMG proteins Nhp6 and Hmo1 can stimulate SWI/SNF activity. Here, we studied the genome-wide binding patterns of Nhp6, Hmo1 and the SWI/SNF complex, finding that most of gene promoters presenting high occupancy of this complex also display high enrichment of these HMG proteins...

Aptamers are single-stranded oligonucleotides that recognize molecular targets with high affinity and specificity. Aptamer that selectively bind to the protein tyrosine kinase-7 (PTK7) receptor, overexpressed on many cancers, has been labelled as probes for molecular imaging of cancer. Two new PTK7-targeting aptamer probes were developed by coupling frameworks from the fluorescent dye AlexaFluor647 or the 6-hydrazinonicotinamide (HYNIC) chelator-labelled to (99m)Tc. The derivatizations via a 5'-aminohexyl terminal linker were done at room temperature and under mild buffer conditions...

Natural killer (NK) cells are alerted to infected and transformed cells by local upregulation of ligands for the NK-activating receptor NKG2D. In a recent report, Greene et al. unveil a new mechanism that induces the expression of the NKG2D ligand retinoic acid early-inducible (RAE-1) in response to murine cytomegalovirus (MCMV) infection through inhibition of casein kinase 2 (CK2), an activator of the repressor histone deacetylase HDAC3.

BACKGROUND & AIMS: Modulation of microRNA expression is considered for treatment of hepatocellular carcinoma (HCC). Therefore, we characterized the epigenetically regulated microRNA-449 family (miR-449a, miR-449b, miR-449c) with regards to its functional effects and target genes in HCC. METHODS: After transfection of miR-449a, miR-449b, and/or miR-449c, tumor-relevant functional effects were analyzed using in vitro assays and a xenograft mouse model. Binding specificities, target genes, and regulated pathways of each microRNA were identified by microarray analyses...

An endoplasmic reticulum (ER)-resident protein that regulates cytosolic and ER free-Ca(2+) concentration by induction of store-operated calcium entry. That is the original definition of STIM2 and its function. While its activity strongly depends on the amount of calcium stored in the ER, its function goes further to intracellular signalling and gene expression. Initially undercovered by the prominent function of STIM1, STIM2 became to be vital in mice, gradually emerging as an important player in the nervous system, and cooperating with STIM1 in the immune system...

Mal de Río Cuarto virus (MRCV) is a member of the Fijivirus genus, within the Reoviridae family, that replicates and assembles in cytoplasmic inclusion bodies called viroplasms. In this study, we investigated interactions between ten MRCV proteins by yeast two-hybrid (Y2H) assays and identified interactions of non-structural proteins P6/P6, P9-2/P9-2 and P6/P9-1. P9-1 and P6 are the major and minor components of the viroplasms respectively, whereas P9-2 is an N-glycosylated membrane protein of unknown function...

The introduction of Proprotein covertase subtilisin/kexin type 9 (PCSK9) inhibitors has been heralded as a major advancement in reducing low-density lipoprotein cholesterol levels by nearly 50%. However, concerns have been raised on the added value to the health care system in terms of their costs and benefits. We assess the cost-effectiveness of PCSK9 inhibitors based on a decision-analytic model with existing clinical evidence. The model compares a lipid-lowering therapy based on statin plus PCSK9 inhibitor treatment with statin treatment only (standard therapy)...
