Drug hypersensitivity reactions result from the activation of the immune system by drugs or their metabolites. The clinical presentations of drug hypersensitivity can range from relatively mild local manifestations to severe systemic syndromes that can be life-threatening. As in other allergic reactions, the causes are multifactorial as genetic, metabolic and concomitant factors may influence the occurrence of drug hypersensitivity. Formation of drug protein adducts is considered a key step in drug adverse reactions, and in particular in the immunological recognition in drug hypersensitivity reactions...

Despite being the most common liver cancer in children, hepatoblastoma (HB) is a rare neoplasm. Consequently, few pre-treatment tumors have been molecularly profiled and there are no validated prognostic or therapeutic biomarkers for HB patients. We report on the first large-scale effort to profile pre-treatment HBs at diagnosis. Our analysis of 88 clinically-annotated HBs revealed three risk-stratifying molecular subtypes that are characterized by differential activation of hepatic progenitor cell markers and metabolic pathways: high-risk tumors were characterized by up-regulated NFE2L2 activity, high LIN28B, HMGA2, SALL4 and AFP expression, and high coordinated expression of oncofetal proteins and stem cell markers; while low-risk tumors had low LIN28B and let-7 expression, and high HNF1A activity...

The current categorization of chronic kidney disease (CKD) is based on biomarkers of the glomerular function (estimated glomerular filtration rate, eGFR) and injury (urinary albumin creatinine ratio, UACR) and provides information on the risk of death and of progression of kidney disease. However, there are gaps in knowledge regarding the risk stratification of elderly patients with eGFR 45-60 ml/min/1.73 m2 and of younger patients with higher eGFR but physiological albuminuria. In this regard, most of the kidney cell mass is composed of tubules...

Human Mycobacterium bovis infections are considered to be due to reactivations, when involve elderly people, or to recent transmissions, when exposure is occupational. We determined the cause of M. bovis infections by genotyping M. bovis isolates in a population-based study integrating human and animal databases. Among the 1,586 tuberculosis (TB) cases in Asturias, Northern Spain (1,080,000 inhabitants), 1,567 corresponded to M. tuberculosis and 19 to M. bovis. The number of human isolates sharing genotype with cattle isolates was higher than expected (47%) for a setting with low prevalence of bovine TB and efficient control programs in cattle...

Different molecular techniques have been developed to study either the global level of methylated cytosines or methylation at specific gene sequences. One of them is the methylation-sensitive amplified polymorphism technique (MSAP) which is a modification of amplified fragment length polymorphism (AFLP). It has been used to study methylation of anonymous CCGG sequences in different fungi, plants, and animal species. The main variation of this technique resides on the use of isoschizomers with different methylation sensitivity (such as HpaII and MspI) as a frequent-cutter restriction enzyme...

This study reports the characterization and antiproliferative activity of exopolysaccharides (EPS) produced by submerged cultures of the endophytes Diaporthe sp. JF766998 and Diaporthe sp. JF767007 isolated from the medicinal plant Piper hispidum Sw. Both strains secreted a crude EPS that, upon size exclusion chromatography, showed to contain a heteropolysaccharide (galactose, glucose and mannose) and a high-molecular weight glucan. Data from methylation analysis, FTIR and NMR spectroscopy ((1)H, COSY, TOCSY and HSQC-DEPT) indicated that the purified glucan consisted of a main chain of glucopyranosyl β-(1→3) linkages substituted at O-6 by glucosyl residues...

Chronic kidney disease (CKD) is associated to an increased risk of death, CKD progression and acute kidney injury (AKI) even from early stages, when glomerular filtration rate (GFR) is preserved. The link between early CKD and these risks is unclear, since there is no accumulation of uremic toxins. However, pathological albuminuria and kidney inflammation are frequent features of early CKD and the production of kidney protective factors may be decreased. Indeed, Klotho expression is already decreased in CKD category G1 (normal GFR)...

Current recommendations for diagnosing myelodysplastic syndromes endorse flow cytometry as an informative tool. Most flow cytometry protocols focus on the analysis of progenitor cells and the evaluation of the maturing myelomonocytic lineage. However, one of the most frequently observed features of myelodysplastic syndromes is anemia, which may be associated with dyserythropoiesis. Therefore, analysis of changes in flow cytometry features of nucleated erythroid cells may complement current flow cytometry tools...

The lymphocystis disease virus (LCDV), a member of the Iridoviridae family, infects a wide range of fish species including gilthead seabream (Sparus aurata L.), the most important species cultured in the Mediterranean. LCDV is difficult to propagate in cell culture and does not produce clear and consistent cytopathic effects (CPE), especially in samples collected from subclinically infected fish. An integrated cell culture reverse transcription-polymerase chain reaction (ICC-RT-PCR) assay, followed by dot-blot hybridization of the RT-PCR products, was developed to improve the detection of infectious LCDV...

In couples with infertility, abnormal strict morphology of 0% normal forms (NF) is a criterion to proceed rapidly to in vitro fertilization (IVF). Since no data currently exist, we investigated the outcomes for men with 0% NF to determine reproductive success without the use of assisted reproductive technologies (ART). A cohort of 24 men with 0% NF were identified (2010-2013) with 27 randomly selected men with ≥4% NF as controls. Patient charts were reviewed with men contacted and administered an Institutional Review Board (IRB)-approved telephone questionnaire to ascertain outcomes...
