Junichiro Sonoda, Mark Z Chen, Amos Baruch
Fibroblast growth factor 21 (FGF21) analogs and FGF21 receptor agonists (FGF21RAs) that mimic FGF21 ligand activity constitute the new "FGF21-class" of anti-obesity and anti-diabetic molecules that improve insulin sensitivity, ameliorate hepatosteatosis and promote weight loss. The metabolic actions of FGF21-class proteins in obese mice are attributed to stimulation of brown fat thermogenesis and increased secretion of adiponectin. The therapeutic utility of this class of molecules is being actively investigated in clinical trials for the treatment of type 2 diabetes and non-alcoholic steatohepatitis (NASH)...

Syncope is a common and a typically benign clinical problem in children and adolescents. The majority of tests ordered in otherwise healthy pediatric patients presenting with syncope have low diagnostic yield. This study quantifies testing and corresponding patient charges in a group of pediatric patients presenting for outpatient evaluation for syncope. Patients seen between 3/2011 and 4/2013 in the multi-disciplinary Syncope Clinic at Cincinnati Children's Hospital Medical Center were enrolled in a registry which was reviewed for patient information...

Rho GTPases control cell division, motility, adhesion, vesicular trafficking and phagocytosis, which may affect progression and/or prognosis of cancers. Here, we investigated associations between genetic variants of Rho GTPases-related genes and cutaneous melanoma-specific survival (CMSS) by re-analyzing a published melanoma genome-wide association study (GWAS) and validating the results in another melanoma GWAS. In the single-locus analysis of 36,018 SNPs in 129 Rho-related genes, 427 SNPs were significantly associated with CMSS (P<0...

Organophosphates (OP) are used extensively as pesticides and as chemical weapons. Cardiotoxicity is a major concern in survivors of the acute poisoning. To characterize the delayed cardiac effects of OP, rats were poisoned by intraperitoneal administration of dichlorvos. In group I, poisoning (0.25-, 0.75-, 1.4-LD50) was followed by application of atropine and obidoxime. In group II, poisoning (0.35-, 0.5-LD50) was done without antidotes. Cardiac evaluation included electrocardiography and echocardiography 2- and 6-week post-exposure, arrhythmia susceptibility following administration of Isoproterenol (150 mcg/kg), and histological evaluation...

Ras associated lymphoproliferative disease (RALD) is an autoimmune lymphoproliferative syndrome (ALPS)-like disease caused by mutations in KRAS or NRAS. The immunological phenotype and pathogenesis of RALD have yet to be extensively studied. Here we report a thorough immunological investigation of a RALD patient with a somatic KRAS mutation. Patient lymphocytes were analyzed for phenotype, immunoglobulin levels and T cell proliferation capacity. T and B cell receptor excision circles (TREC and KREC, respectively), markers of naïve T and B cell production, were serially measured over three years...

Linda A Amos, Jan Löwe
As discovered over the past 25 years, the cytoskeletons of bacteria and archaea are complex systems of proteins whose central components are dynamic cytomotive filaments. They perform roles in cell division, DNA partitioning, cell shape determination and the organisation of intracellular components. The protofilament structures and polymerisation activities of various actin-like, tubulin-like and ESCRT-like proteins of prokaryotes closely resemble their eukaryotic counterparts but show greater diversity. Their activities are modulated by a wide range of accessory proteins but these do not include homologues of the motor proteins that supplement filament dynamics to aid eukaryotic cell motility...

Cutaneous melanoma (CM) is the most lethal skin cancer. The Wnt pathway has an impact on development, invasion and metastasis of CM, thus likely affecting CM prognosis. Using data from a published genome-wide association study (GWAS) from The University of Texas M.D. Anderson Cancer Center, we assessed the associations of 19,830 common single-nucleotide polymorphisms (SNPs) in 151 Wnt pathway autosomal genes with CM-specific survival (CMSS) and then validated significant SNPs in another GWAS from Harvard University...

SIRS is associated with lymphopenia, and prolonged lymphopenia of septic patients has been associated with increased mortality risk. We hypothesize that elevated adenosine during SIRS down-regulates Gi-coupled A1R, which signals an effect that sensitizes a cAMP-dependent lymphotoxic response. In this study, we evaluate the role of adenosine in SIRS-mediated lymphopenia and impaired IL-15 production. Cecal ligation and puncture was used to induce sepsis-associated SIRS in mice. BMDCs were cultured and used to measure the effect of adenosine on IL-15...

The envelope glycoproteins (Envs) on the surface of HIV-1 particles are targeted by host antibodies. Primary HIV-1 isolates demonstrate different global sensitivities to antibody neutralization; Tier-1 isolates are sensitive whereas Tier-2 isolates are more resistant. Single-site mutations in Env can convert Tier-2 into Tier-1-like viruses. We hypothesized that such global change in neutralization sensitivity results from weakening of intra-molecular interactions that maintain Env integrity. Three strategies commonly applied to perturb protein structure were tested for their effect on global neutralization sensitivity; exposure to low temperature, Env-activating ligands and a chaotropic agent...

Obesity, mild intellectual disability, hypotonia, poor sucking, cryptorchidism in males, hypogonadism, and kyphoscoliosis are common features of Prader-Willi syndrome (PWS). We report a case who had severe respiratory complications due to extreme obesity and kyphoscoliosis, which are important causes of morbidity and mortality, and discuss management. Furthermore, this is the first molecularly confirmed PWS case in Sub-Saharan Africa outside South Africa.

Conjunctiva occupies most of the ocular surface area, and conjunctival permeability affects ocular and systemic drug absorption from topical ocular medications. Therefore, the aim of this study was to obtain a computational in silico model for structure-based prediction of conjunctival drug permeability. This was done by employing cassette dosing and quantitative structure-property relationship (QSPR) approach. Permeability studies were performed ex vivo across fresh porcine conjunctiva and simultaneous dosing of a cassette mixture composed of 32 clinically relevant drug molecules with wide chemical space...
