A 3D MRI‐based atlas of a lizard brain
(Wiley, 2018)Magnetic resonance imaging (MRI) is an established technique for neuroanatomical analysis, being particularly useful in the medical sciences. However, the application of MRI to evolutionary neuroscience is still in its ... -
A common copy-number variant within SIRPB1 correlates with human Out-of-Africa migration after genetic drift correction
(Public Library of Science, 2018)Previous reports have proposed that personality may have played a role on human Out-Of- Africa migration, pinpointing some genetic variants that were positively selected in the migrating populations. In this work, we ... -
A genome-wide transcriptional study reveals that iron deficiency inhibits the yeast TORC1 pathway
(Elsevier, 2019-09)Iron is an essential micronutrient that participates as a cofactor in a broad range of metabolic processes including mitochondrial respiration, DNA replication, protein translation and lipid biosynthesis. Adaptation to ... -
A low fractional excretion of Phosphate/Fgf23 ratio is associated with severe abdominal Aortic calcification in stage 3 and 4 kidney disease patients
(BioMed Central, 2013)Background: Vascular calcification (VC) contributes to high mortality rates in chronic kidney disease (CKD). High serum phosphate and FGF23 levels and impaired phosphaturic response to FGF23 may affect VC. Therefore, ... -
A model of protein association based on their hydrophobic and electric interactions
(Public Library of Science, 2014)The propensity of many proteins to oligomerize and associate to form complex structures from their constituent monomers, is analyzed in terms of their hydrophobic (H), and electric pseudo-dipole (D) moment vectors. In ... -
A New Gender-Specific Formula to Estimate 24-Hour Urine Protein from Protein to Creatinine Ratio
(Karger, 2016-07-20)Background: The quantification of proteinuria with the protein to creatinine ratio (PCR) is influenced by the excretion of creatinine, which, in turn, varies according to muscle mass and hence, to gender. Aims: To assess ... -
A Novel Rat Model of Vitamin D Deficiency: Safe and Rapid Induction of Vitamin D and Calcitriol Deficiency without Hyperparathyroidism
(Hindawi, 2015)Vitamin D deficiency is associated with a range of clinical disorders. To study the mechanisms involved and improve treatments, animal models are tremendously useful. Current vitamin D deficient rat models have important ... -
A novel source for miR-21 expression through the alternative polyadenylation of VMP1 gene transcripts
(Oxford University Press, 2012)miR-21 is the most commonly over-expressed microRNA (miRNA) in cancer and a proven oncogene. Hsa-miR-21 is located on chromosome 17q23.2, immediately downstream of the vacuole membrane protein-1 (VMP1) gene, also known as ... -
A pathway involving HDAC5, cFLIP and caspases regulates expression of the splicing regulator polypyrimidine tract binding protein in the heart
(Company of Biologists Ltd., 2013)Polypyrimidine tract binding protein (PTB) regulates pre-mRNA splicing, having special relevance for determining gene expression in the differentiating muscle. We have previously shown that PTB protein abundance is ... -
A peroxisomal glutathione transferase of Saccharomyces cerevisiae is functionally related to sulfur amino acid metabolism
(American Society for Microbiology, 2006)Saccharomyces cerevisiae cells contain three omega-class glutathione transferases with glutaredoxin activity (Gto1, Gto2, and Gto3), in addition to two glutathione transferases (Gtt1 and Gtt2) not classifiable into standard ... -
A pilot study on the diagnostic accuracy of proadrenomedullin and proatrial natriuretic Peptide in lower respiratory tract infections
(Bentham Open, 2014)Abstract: Background: Pneumonia is the leading cause of death among infectious diseases in developed countries. However, the severity of pneumonia requiring hospitalization often makes the initial diagnosis difficult ... -
A plasma metabolomic signature discloses human breast cancer
(Impact Journals, 2017)Purpose: Metabolomics is the comprehensive global study of metabolites in biological samples. In this retrospective pilot study we explored whether serum metabolomic profile can discriminate the presence of human breast ... -
A prospective cross-sectional study on quality of life and treatment satisfaction in type 2 diabetic patients with retinopathy without other major late diabetic complications
(BioMed Central, 2014)Background: To assess quality of life and treatment satisfaction in patients with type 2 diabetes mellitus with diabetic retinopathy (DR) using validated instruments, with comparison to patients without DR. Methods: A ... -
A prospective pilot study using metabolomics discloses specific fatty acid, catecholamine and tryptophan metabolic pathways as possible predictors for a negative outcome after severe trauma
(BMC (part of Springer Nature), 2019-05-22)Background: We wanted to define metabolomic patterns in plasma to predict a negative outcome in severe trauma patients. Methods: A prospective pilot study was designed to evaluate plasma metabolomic patterns, established ... -
A queuing theory model for cloud computing
(Springer Verlag, 2014-04)The ability to deliver guaranteed QoS (Quality of Service) is crucial for the commercial success of cloud platforms. This paper presents a model based on queuing theory to study computer service QoS in cloud computing. ... -
A Review of Clinical Studies and Practical Guide for the Administration of Triplet Chemotherapy Regimens with Bevacizumab in First-line Metastatic Colorectal Cancer
(Springer, 2016)Colorectal cancer is the third most common cancer worldwide. A significant proportion of patients presents with unresectable metastatic disease or develops metachronous metastases following surgical resection of the primary ... -
A review on the use of NEO-PI-R validity scales in normative, job selection, and clinical samples
(Universidad de Zaragoza, 2009)Background and Objectives: In this study we review the use of the Positive Presentation Management (PPM) and Negative Presentation Management (NPM) scales, two NEO-PI-R derived measures originally devised to control for ... -
A salmon peptide diet alleviates experimental colitis as compared with fish oil
(Cambridge University Press, 2013)Fish oil (FO) has been shown to have anti-inflammatory properties in animal models of inflammatory bowel disease, but how fish peptides (FP) influence intestinal inflammation has been less studied. Male Wistar rats, divided ... -
