Genome-wide association studies (GWASs) have identified 19 susceptibility loci for Alzheimer's disease (AD). However, understanding how these genes are involved in the pathophysiology of AD is one of the main challenges of the "post-GWAS" era. At least 123 genes are located within the 19 susceptibility loci; hence, a conventional approach (studying the genes one by one) would not be time- and cost-effective. We therefore developed a genome-wide, high-content siRNA screening approach and used it to assess the functional impact of gene under-expression on APP metabolism...

INTRODUCTION: Elective heart transplantation (HTX) aims to improve physical ability, increase survival, and improve health-related quality of life (HRQoL) in patients with chronic heart failure. Nevertheless, most patients who undergo urgent HTX are previously healthy, and a transplant could be perceived as a limitation. The aim of this study is to compare HRQoL between elective and urgent heart transplant recipients. METHODS: Cohort study including patients undergoing heart transplantation between January 1998 and March 2012 in a single center...

Elucidation of interactions involving DNA and histone post-translational-modifications (PTMs) is essential for providing insights into complex biological functions. Reader assemblies connected by flexible linkages facilitate avidity and increase affinity; however, little is known about the contribution to the recognition process of multiple PTMs because of rigidity in the absence of conformational flexibility. Here, we resolve the crystal structure of the triple reader module (PHD-BRD-PWWP) of ZMYND8, which forms a stable unit capable of simultaneously recognizing multiple histone PTMs while presenting a charged platform for association with DNA...

Oligoynes are archetypical molecular wires due to their 1-D chain of conjugated carbon atoms and ability to transmit charge over long distances by coherent tunneling. However, the stability of the oligoyne can be an issue. Here we address this problem by two stabilization methods, namely sterically shielding endgroups, and rotaxination to produce an insulated molecular wire. We demonstrate the threading of a hexayne within a macrocycle to form a rotaxane and report measurements of the electrical conductance of this single supramolecular assembly within an STM break junction...

The complete nucleotide sequence of a new soybean-infecting member of the genus Nepovirus (provisionally named "soybean latent spherical virus" [SLSV]) was identified by high-throughput sequencing of RNAs from soybean leaf samples from North Dakota, USA. The sequences of RNAs 1 (8,190 nt) and 2 (5,788 nt) were completed by rapid amplification of cDNA ends. Each contained a single long open reading frame and a 3' nontranslated region of greater than 1,500 nt. The predicted amino acid sequences of the two ORFs were most closely related to nepoviruses in subgroup C...

Talley J Lambert, Jennifer C Waters
In 2014, the Nobel Prize in Chemistry was awarded to three scientists who have made groundbreaking contributions to the field of superresolution (SR) microscopy (SRM). The first commercial SR microscope came to market a decade earlier, and many other commercial options have followed. As commercialization has lowered the barrier to using SRM and the awarding of the Nobel Prize has drawn attention to these methods, biologists have begun adopting SRM to address a wide range of questions in many types of specimens...

OBJECTIVE: To determine if there was an association between vasectomy utilization and offspring sex ratio (Male offspring: Total offspring) as offspring sex preference may have an impact on family planning in the United States. STUDY DESIGN: Using data from the NIH-AARP Diet and Health Study, we calculated the numbers of sons and daughters for all men stratified by vasectomy status. We utilized a logistic regression model to determine if vasectomy utilization varies based on offspring sex ratio while accounting for known factors that impact vasectomy utilization...

Bacteria often produce extracellular amyloid fibres via a multi-component secretion system. Aggregation-prone, unstructured subunits cross the periplasm and are secreted through the outer membrane, after which they self-assemble. Here, significant progress is presented towards solving the high-resolution crystal structure of the novel amyloid transporter FapF from Pseudomonas, which facilitates the secretion of the amyloid-forming polypeptide FapC across the bacterial outer membrane. This represents the first step towards obtaining structural insight into the products of the Pseudomonas fap operon...

Until recently, genes coding for homologues of the autofluorescent protein GFP had only been identified in marine organisms from the phyla Cnidaria and Arthropoda. New fluorescent-protein genes have now been found in the phylum Chordata, coding for particularly bright oligomeric fluorescent proteins such as the tetrameric yellow fluorescent protein lanYFP from Branchiostoma lanceolatum. A successful monomerization attempt led to the development of the bright yellow-green fluorescent protein mNeonGreen. The structures of lanYFP and mNeonGreen have been determined and compared in order to rationalize the directed evolution process leading from a bright, tetrameric to a still bright, monomeric fluorescent protein...

During DNA replication, proliferating cell nuclear antigen (PCNA) adopts a ring-shaped structure to promote processive DNA synthesis, acting as a sliding clamp for polymerases. Known posttranslational modifications function at the outer surface of the PCNA ring to favor DNA damage bypass. Here, we demonstrate that acetylation of lysine residues at the inner surface of PCNA is induced by DNA lesions. We show that cohesin acetyltransferase Eco1 targets lysine 20 at the sliding surface of the PCNA ring in vitro and in vivo in response to DNA damage...

A question is raised about an increased risk of severe infection from the use of biological drugs in patients with rheumatoid arthritis. This systematic review of observational studies aimed at assessing the risk of severe infection associated with the use of anakinra, rituximab, and abatacept in patients with rheumatoid arthritis. The following databases were searched: PubMed, Science Direct, Scopus, Web of Knowledge, Scirus, Cochrane, Exerpta Medica Database, Scielo, and Lilacs up to July 2010. Severe infections were defined as those life-threatening ones in need of the use of parenteral antibiotics or of hospitalization...
