Discrimination between different gases is an essential aspect for industrial and environmental applications involving sensing and separation. Several classes of porous materials have been used in this context, including zeolites and more recently MOFs. However, to reach high selectivities for the separation of gas mixtures is a challenging task that often requires the understanding of the specific interactions established between the porous framework and the gases. Here we propose an approach to obtain an enhanced selectivity based on the use of compartmentalized coordination polymers, named CCP-1 and CCP-2, which are crystalline materials comprising isolated discrete cavities...

Influenza viruses continue to be a major public health concern, despite the availability of vaccines. Currently licensed influenza vaccines aim at the induction of antibodies that target hemagglutinin, the major antigenic determinant on the surface of influenza virions that is responsible for attachment of the virus to the host cell that is to be infected. Currently licensed influenza vaccines come as inactivated or live attenuated influenza vaccines and are trivalent or quadrivalent as they contain antigens of two influenza A and one or two influenza B strains that circulate in the human population, respectively...

Liver transplantation (LT) is indicated in autoimmune hepatitis (AIH) for both acute presentation with liver failure and end-stage chronic liver disease. Few studies have suggested an association between AIH and coagulation disorders and a higher incidence of portal vein thrombosis (PVT) in patients with AIH listed for LT. The aim of this study was to determine the incidence of thrombotic complications, particularly PVT, in a cohort of 37 patients undergoing LT because of AIH. PVT was present before transplantation in 30% (n=11) of these patients compared to 11% in the whole population transplanted in our centre (p=0...

The locus CDKN2A/B (9p21.3), which comprises the tumor suppressors genes CDKN2A and CDKN2B and the long noncoding RNA (lncRNA) known as ANRIL (or CDKN2B-AS), was associated with childhood acute lymphoblastic leukemia (ALL) susceptibility in several genome wide association studies (GWAS). However, the variants associated in the diverse studies were different. Recently, new and independent SNPs deregulating the locus function were also identified in association with ALL risk. This diversity in the results may be explained because different variants in each population could alter CDKN2A/B locus function through diverse mechanisms...

The nuclear RNA exosome is an essential multi-subunit complex that controls RNA homeostasis. Congenital mutations in RNA exosome genes are associated with neurodegenerative diseases. Little is known about the role of the RNA exosome in the cellular response to pathogens. Here, using NGS and human and mouse genetics, we show that influenza A virus (IAV) ribogenesis and growth are suppressed by impaired RNA exosome activity. Mechanistically, the nuclear RNA exosome coordinates the initial steps of viral transcription with RNAPII at host promoters...

OBJECTIVES: Pancreatic ductal adenocarcinoma (PDAC) is thought to derive from different precursor lesions including the recently identified atypical flat lesions (AFL). While all precursor lesions and PDAC share ductal characteristics, there is an ongoing debate about the cellular origin of the different PDAC precursor lesions. In particular, pancreatic acinar cells have previously been shown to display a remarkable plasticity being able to undergo ductal dedifferentiation in the context of oncogenic stimuli...

Melanocortin 1 receptor (MC1R) and BRAF are common mutations in melanoma. Through different pathways, they each regulate the expression of PGC-1α, which is a key factor in the regulation of mitochondrial biogenesis and the antioxidant response. Our aim was to study the importance of the different regulatory characteristics of MC1R and BRAF on the pathways they regulate in melanoma. For this purpose, ROS production, levels of gene expression and enzymatic activities were analyzed in HBL and MeWo, with wild-type MC1R and BRAF, and A375 cells with mutant MC1R and BRAF...

Tumor necrosis factor-like weak inducer of apoptosis (TWEAK/Tnfsf12) is a cytokine implicated in different steps associated with vascular remodeling. However, the role of TWEAK under hyperglycemic conditions is currently unknown. Using two different approaches, genetic deletion of Tnfsf12 and treatment with a TWEAK blocking mAb, we have analyzed the effect of TWEAK inhibition on atherosclerotic plaque progression and stability in streptozotocin-induced diabetic ApoE deficient mice. Genetic inactivation of Tnfsf12 reduced atherosclerosis extension and severity in diabetic ApoE deficient mice...

BACKGROUND AND AIMS: Meningococcal C conjugate (MCC) vaccination programs provide direct and indirect protection against meningococcal disease. However, a decrease in the antibodies could affect herd immunity. We conducted a seroprevalence study to assess the immunity in subjects 8-12years after different MCCV vaccination programs were launched and evaluated the impact of vaccination on seroprotection. METHODS: Seroepidemiological study conducted from October 2010 to April 2012 in the region of Valencia, Spain...

Healthcare funding decisions in the UK rely on health state valuations of the general public. However, it has been shown that there is disparity between the valuation of the impact of hypothetical conditions on health and the reported health by those experiencing them. Patients' adaptation to health states is among the most common explanations for this discrepancy. Being diagnosed with a disease appears to affect individual perception of health over time so that better subjective health may be reported over a disease trajectory...

There is evidence of a neurodegenerative process running in parallel with or as a consequence of the inflammatory phenomenon in multiple sclerosis (MS). MR imaging has been central in the generation of such knowledge and has played a pivotal role in investigating the neurodegenerative process. However, there is insufficient evidence supporting MR imaging-measured brain atrophy as a biomarker of the neurodegenerative component of MS in the daily care of patients with MS. This article discusses the prognostic value of brain volume measurements and their potential role in monitoring treatment response in patients with MS...

Ebola virus (EBOV) protein VP35 inhibits production of interferon alpha/beta (IFN) by blocking RIG-I-like receptor signaling pathways, thereby promoting virus replication and pathogenesis. A high-throughput screening assay, developed to identify compounds that either inhibit or bypass VP35 IFN-antagonist function, identified five DNA intercalators as reproducible hits from a library of bioactive compounds. Four, including doxorubicin and daunorubicin, are anthracycline antibiotics that inhibit topoisomerase II and are used clinically as chemotherapeutic drugs...
