    Embryonic vascular disruption adverse outcomes: Linking HIGH throughput signaling signatures with functional consequences.
    Reprod Toxicol 2017 May 17. Epub 2017 May 17.
    Toxicology and Environmental Research and Consulting, The Dow Chemical Company, 1803 Building, Midland, MI 48674, United States.
    Embryonic vascular disruption is an important adverse outcome pathway (AOP) as chemical disruption of cardiovascular development induces broad prenatal defects. High throughput screening (HTS) assays aid AOP development although linking in vitro data to in vivo apical endpoints remains challenging. This study evaluated two anti-angiogenic agents, 5HPP-33 and TNP-470, across the ToxCastDB HTS assay platform and anchored the results to complex in vitro functional assays: the rat aortic explant assay (AEA), rat whole embryo culture (WEC), and the zebrafish embryotoxicity (ZET) assay.

    Centre for Endocrinology, William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, Charterhouse Square, London EC1M 6BQ, UK. Electronic address:
    Although most of pituitary adenomas are benign, they may cause significant burden to patients. Sporadic adenomas represent the vast majority of the cases, where recognized somatic mutations (eg, GNAS or USP8), as well as altered gene-expression profile often affecting cell cycle proteins have been identified. More rarely, germline mutations predisposing to pituitary adenomas -as part of a syndrome (eg, MEN1 or Carney complex), or isolated to the pituitary (AIP or GPR101) can be identified. Read More

    Fibrolamellar carcinoma: A histologically unique tumor with unique molecular findings.
    Semin Diagn Pathol 2017 Mar 23;34(2):146-152. Epub 2016 Dec 23.
    Division of Anatomic Pathology, Mayo Clinic, 200 First Street SW, Rochester, MN, United States.
    Fibrolamellar carcinoma is a unique type of hepatocellular carcinoma with a distinctive predilection for young patients without underlying liver disease, characteristic large neoplastic cells with intervening, dense fibrosis, co-expression of keratin 7 and CD68 and activation of protein kinase A (most often by formation of DNAJB1-PRKACA). Fibrolamellar carcinoma has a similar prognosis to conventional hepatocellular carcinomas arising in non-cirrhotic livers. The current American Joint Cancer Committee staging system does not provide optimal stratification of patients with fibrolamellar carcinoma and an alternate systems should be considered in the future.

    Extraction chromatographic separations of tantalum and tungsten from hafnium and complex matrix constituents.
    J Chromatogr A 2017 Feb 8;1484:1-6. Epub 2017 Jan 8.
    Pacific Northwest National Laboratory, PO Box 999, MSIN J4-80, 902 Battelle Blvd, Richland, WA, 99352, USA.
    Tantalum (Ta), hafnium (Hf), and tungsten (W) analyses from complex matrices require high purification of these analytes from each other and major/trace matrix constituents, however, current state-of-the-art Ta/Hf/W separations rely on traditional anion exchange approaches that show relatively similar distribution coefficient (Kd) values for each element. This work reports an assessment of three commercially available extraction chromatographic resins (TEVA, TRU, and UTEVA) for Ta/Hf/W separations. Batch contact studies show differences in Ta/Hf and Ta/W Kd values of up to 10(6) and 10(4) (respectively), representing an improvement of a factor of 100 and 300 in Ta/Hf and Ta/W Kd values (respectively) over AG1×4 resin.

    Widespread Virus Replication in Alveoli Drives Acute Respiratory Distress Syndrome in Aerosolized H5N1 Influenza Infection of Macaques.
    J Immunol 2017 Feb 6;198(4):1616-1626. Epub 2017 Jan 6.
    Center for Vaccine Research, University of Pittsburgh, Pittsburgh, PA 15261;
    Human infections with highly pathogenic avian influenza A (H5N1) virus are frequently fatal but the mechanisms of disease remain ill-defined. H5N1 infection is associated with intense production of proinflammatory cytokines, but whether this cytokine storm is the main cause of fatality or is a consequence of extensive virus replication that itself drives disease remains controversial. Conventional intratracheal inoculation of a liquid suspension of H5N1 influenza virus in nonhuman primates likely results in efficient clearance of virus within the upper respiratory tract and rarely produces severe disease.

    Hereditary syndromes predisposing to endocrine tumors and their skin manifestations.
    Rev Endocr Metab Disord 2016 Sep;17(3):381-388
    Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Building 10, Room East 1330, CRC, 10 Center Dr. MSC1862, Bethesda, MD, 20892-1862, USA.
    We often think of the lentiginoses, phacomatoses and other neurocutaneous syndromes as conditions that affect the skin and also predispose to a variety of tumors. However, we rarely think of Peutz-Jeghers syndrome (PJS), Carney complex (CNC), Cowden disease (CD), neurofibromatosis type-1 (NF-1) or tuberous sclerosis (TSC) as conditions that are multiple endocrine neoplasias (MEN). Indeed, all of these conditions predispose to a variety of endocrine tumors, in addition to many other neoplasms. Read More

    Carney complex: A familial lentiginosis predisposing to a variety of tumors.
    Rev Endocr Metab Disord 2016 Sep;17(3):367-371

    Carney complex is a familial lentiginosis syndrome; these disorders cover a wide phenotypic spectrum ranging from a benign inherited predisposition to develop cutaneous spots not associated with systemic disease to associations with several syndromes. Carney complex is caused by PRKAR1A mutations and perturbations of the cyclic AMP-dependent protein kinase (PKA) signaling pathway. In addition to the cutaneous findings, the main tumors associated with Carney complex are endocrine: 1) primary pigmented nodular adrenocortical disease, a bilateral adrenal hyperplasia leading to Cushing syndrome; 2) growth-hormone secreting pituitary adenoma or pituitary somatotropic hyperplasia leading to acromegaly; 3) thyroid and gonadal tumors, including a predisposition to thyroid cancer.

    J Mol Biol 2016 Dec 5;428(24 Pt B):4890-4904. Epub 2016 Nov 5.
    Department of Chemistry and Biochemistry, University of California at San Diego, La Jolla, CA 92093, USA; Department of Pharmacology, University of California at San Diego, La Jolla, CA 92093, USA. Electronic address:
    Most disease-related mutations that impair cAMP protein kinase A (PKA) signaling are present within the regulatory (R) PKA RI alpha-subunit (RIα). Although mutations in the PRKAR1A gene are linked to Carney complex (CNC) disease and, more recently, to acrodysostosis-1 (ACRDYS1), the two diseases show contrasting phenotypes. While CNC mutations cause increased PKA activity, ACRDYS1 mutations result in decreased PKA activity and cAMP resistant holoenzymes. Read More

    Prkar1a gene knockout in the pancreas leads to neuroendocrine tumorigenesis.
    Endocr Relat Cancer 2017 Jan 1;24(1):31-40. Epub 2016 Nov 1.
    Section on Endocrinology and GeneticsProgram on Developmental Endocrinology & Genetics (PDEGEN) & Pediatric Endocrinology Inter-institute Training Program, Eunice Kennedy Shriver National Institute of Child Health & Human Development (NICHD), National Institutes of Health (NIH), Bethesda, Maryland, USA
    Carney complex (CNC) is a rare disease associated with multiple neoplasias, including a predisposition to pancreatic tumors; it is caused most frequently by the inactivation of the PRKAR1A gene, a regulator of the cyclic AMP (cAMP)-dependent kinase (PKA). The method used was to create null alleles of prkar1a in mouse cells expressing pdx1 (Δ-Prkar1a). We found that these mice developed endocrine or mixed endocrine/acinar cell carcinomas with 100% penetrance by the age of 4-5 months. Read More

    Computed Optical Interferometric Imaging: Methods, Achievements, and Challenges.
    IEEE J Sel Top Quantum Electron 2016 May-Jun;22(3). Epub 2015 Nov 2.
    Beckman Institute for Advanced Science and Technology, also with the Departments of Electrical and Computer Engineering, Bioengineering, and Internal Medicine, University of Illinois at Urbana-Champaign, Urbana, IL 61801 USA.
    Three-dimensional high-resolution optical imaging systems are generally restricted by the trade-off between resolution and depth-of-field as well as imperfections in the imaging system or sample. Computed optical interferometric imaging is able to overcome these longstanding limitations using methods such as interferometric synthetic aperture microscopy (ISAM) and computational adaptive optics (CAO) which manipulate the complex interferometric data. These techniques correct for limited depth-of-field and optical aberrations without the need for additional hardware. Read More

    Posttraumatic epilepsy (PTE) is one of the most common and devastating complications of traumatic brain injury (TBI). Currently, the etiopathology and mechanisms of PTE are poorly understood and as a result, there is no effective treatment or means to prevent it. Antiepileptic drugs remain common preventive strategies in the management of TBI to control acute posttraumatic seizures and to prevent the development of PTE, although their efficacy in the latter case is disputed.

    A 40-year-old man presented with Cushing's syndrome due to bilateral adrenal hyperplasia with multiple nodules. Computed tomography scan results were atypical demonstrating an enlargement of the bilateral adrenal glands harboring multiple small nodules, but the lesion was clinically diagnosed to be primary pigmented nodular adrenocortical disease (PPNAD) based on both endocrinological test results and his family history. We performed bilateral adrenalectomy and confirmed the diagnosis histologically. Read More

    Growth hormone and risk for cardiac tumors in Carney complex.

    Carney complex (CNC) is a multiple neoplasia syndrome that is caused mostly by PRKAR1A mutations. Cardiac myxomas are the leading cause of mortality in CNC patients who, in addition, often develop growth hormone (GH) excess. We studied patients with CNC, who were observed for over a period of 20 years (1995-2015) for the development of both GH excess and cardiac myxomas. Read More

    Evidence-based interventions to improve health care and medical education face multiple complex barriers to adoption and success. Implementation science focuses on the period following research dissemination, which is necessary but insufficient to address important gaps in clinician performance and patient outcomes. This article describes the forces on health care institutions, medical schools, physician clinicians, and trainees that have created the imperative to design educational interventions to address the gap between evidence and practice.
