Evaluation of hetero-multivalent lectin binding using a turbidity-based emulsion agglutination assay.

Colloids Surf B Biointerfaces 2018 Nov 28;175:84-90. Epub 2018 Nov 28.

Dept. of Chemical Engineering, Texas A&M University, College Station, TX, 77843, USA. Electronic address:

Lectin hetero-multivalency, binding to two or more different types of ligands, has been demonstrated to play a role in case of both LecA (a Pseudomonas aeruginosa adhesin) and Cholera Toxin subunit B (a Vibrio cholerae toxin). In order to screen the ligand candidates that involve in hetero-multivalent binding from large molecular libraries, we present a turbidity-based emulsion agglutination (TEA) assay that can be conducted in a high-throughput format using the standard laboratory instruments and reagents. The benefit of this assay is that it relies on the use of emulsions that can be formed using ultrasonication, minimizing the bottleneck of substrate surface functionalization. Read More

Pulmonary impairment following respiratory viral infections is associated with high mortality in allogeneic hematopoietic cell transplant recipients.

Biol Blood Marrow Transplant 2018 Dec 3. Epub 2018 Dec 3.

Infectious Diseases, Infection Control and Employee Health, The University of Texas MD Anderson Cancer Center, Houston, Texas.

Introduction: Pulmonary impairment predicts increased mortality in many settings, and respiratory viral infection (RVI) causes considerable morbidity and mortality in allogeneic hematopoietic cell transplant recipients (allo-HCT). We hypothesized that pulmonary impairment following respiratory viral infection, defined as a decline of forced expiratory volume in 1 second values by ≥10%, may identify allo-HCT recipients at high risk for mortality.

Methods: We studied all allo-HCT recipients at our institution who had RVI with respiratory syncytial virus, parainfluenza virus, or influenza from 2004-2013 and had pre-RVI and post-RVI pulmonary function tests. Read More

Maternal and paternal origin differentially affect prosocial behavior and neural mechanisms in prairie voles.

Behav Brain Res 2018 Dec 3. Epub 2018 Dec 3.

Department of Biology and Integrated Bioscience Program, The University of Akron, Akron, OH, 44325, United States; Department of Biological Sciences, University of Texas at El Paso, El Paso, 79968, United States.

This study tested the hypotheses that maternal and paternal effects differentially influence expression of their offspring's adult behavior and underlying neural mechanisms. We predicted that maternal influences would be greater than paternal influences on male offspring. We tested these hypotheses by cross-breeding two phenotypically-, behaviorally- and neuroanatomically-distinct populations of prairie voles (Microtus ochrogaster) from Illinois, which are highly prosocial, and Kansas, which are significantly less prosocial.

Racial Disparities in Incidence of Young-onset Colorectal Cancer and Patient Survival.

Gastroenterology 2018 Dec 3. Epub 2018 Dec 3.

Department of Epidemiology and Center for Gastrointestinal Biology and Disease, University of North Carolina at Chapel Hill, Chapel Hill, NC.

Background & Aims: Increasing rates of young-onset colorectal cancer (CRC) have attracted substantial research and media attention, but we know little about racial disparities among younger adults with CRC. We examined racial disparities in young-onset CRC by comparing CRC incidence and relative survival among younger (age <50 years) adults, in 2 time periods.

Methods: Using data from the Surveillance, Epidemiology, and End Results program of cancer registries, we estimated CRC incidence rates (per 100,000 persons ages 20 - 54 years) from 1992 through 2014, for different time periods (1992-1996 vs 2010-2014) and races (white vs black). Read More

Vascular and metabolic profiles in offspring born to pregnant mice with metabolic syndrome treated with inositols.

Am J Obstet Gynecol 2018 Dec 3. Epub 2018 Dec 3.

Division of Maternal Fetal Medicine, Department of Obstetrics, Gynecology and Reproductive Sciences, University of Texas Health Science Center at Houston, Houston, Texas.

Background: Inositols (INOs) supplementation during pregnancy, specifically the combination of myo-inositol (MI) and D-chiro-inositol (DCI), has been reported to improve vascular parameters in women with gestational diabetes mellitus. We demonstrated previously that offspring born to pregnant mice lacking endothelial nitric oxide synthase (eNOS+/-) gene have hypertension (HTN) as adults and when fed high fat diet (HFD) develop a metabolic syndrome (MS) phenotype.

Objective: Our aim was to evaluate if INOs treatment in pregnancy complicated by MS improves the vascular and metabolic profile in mice offspring programmed in utero to develop HTN and MS. Read More

Acute effects of zinc and insulin on arcuate anorexigenic Proopiomelanocortin (POMC) neurons.

Br J Pharmacol 2018 Dec 6. Epub 2018 Dec 6.

Division of Hypothalamic Research, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas, USA.

Background And Purpose: Acute insulin administration results in a hyperpolarization and concomitant decrease of firing rate in a subpopulation of arcuate Proopiomelanocortin (POMC) and Neuropeptide Y/Agouti-related peptide (NPY/AgRP) cells. This rapid effect on cellular activity has been implicated as a cellular correlate of insulin effects on energy balance and glucose homeostasis. Recent evidence suggests that zinc in mammalian insulin formulations is required for the insulin-induced inhibition of arcuate POMC neurons, while guinea-pig insulin, which fails to bind zinc, activates POMC neurons in mice.

Transmission dynamics of re-emerging rabies in domestic dogs of rural China.

PLoS Pathog 2018 Dec 6;14(12):e1007392. Epub 2018 Dec 6.

KU Leuven, Department of Microbiology and Immunology, Rega Institute, Laboratory of Evolutionary and Computational Virology, Leuven, Belgium.

Despite ongoing efforts to control transmission, rabies prevention remains a challenge in many developing countries, especially in rural areas of China where re-emerging rabies is under-reported due to a lack of sustained animal surveillance. By taking advantage of detailed genomic and epidemiological data for the re-emerging rabies outbreak in Yunnan Province, China, collected between 1999 and 2015, we reconstruct the demographic and dispersal history of domestic dog rabies virus (RABV) as well as the dynamics of dog-to-dog and dog-to-human transmission. Phylogeographic analyses reveal a lower diffusion coefficient than previously estimated for dog RABV dissemination in northern Africa. Read More

Extracellular polymeric substances (EPS) producing and oil degrading bacteria isolated from the northern Gulf of Mexico.

PLoS One 2018 6;13(12):e0208406. Epub 2018 Dec 6.

Department of Marine Biology, Texas A&M University at Galveston, Galveston, Texas, United States of America.

Sinking marine oil snow was found to be a major mechanism in the transport of spilled oil from the surface to the deep sea following the Deepwater Horizon (DwH) oil spill. Marine snow formation is primarily facilitated by extracellular polymeric substances (EPS), which are mainly composed of proteins and carbohydrates secreted by microorganisms. While numerous bacteria have been identified to degrade oil, there is a paucity of knowledge on bacteria that produce EPS in response to oil and Corexit exposure in the northern Gulf of Mexico (nGoM).

Validation of the 2017 European LeukemiaNet classification for acute myeloid leukemia with NPM1 and FLT3-internal tandem duplication genotypes.

Cancer 2018 Dec 6. Epub 2018 Dec 6.

Department of Leukemia, The University of Texas MD Anderson Cancer Center, Houston, Texas.

Background: The revised 2017 European LeukemiaNet (ELN) classification (ELN-2017) of acute myeloid leukemia (AML) divides patients into 3 prognostic risk categories, with additional factors such as the fms-like tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD) allele ratio (AR) considered for risk stratification. To the best of the authors' knowledge, the prognostic usefulness of ELN-2017 in comparison with ELN-2010 in younger patients with AML has not been validated to date.

Methods: The authors performed a retrospective study on patients aged <60 years who received idarubicin plus cytarabine (IA)-based induction chemotherapy for newly diagnosed AML. Read More

Self-management intervention for head and neck cancer couples: Results of a randomized pilot trial.

Cancer 2018 Dec 6. Epub 2018 Dec 6.

Department of Radiation Oncology, Baylor College of Medicine, Houston, Texas.

Background: Patients with head and neck cancer (HNC) experience significant physical and psychological morbidity during radiotherapy (RT) that contributes to treatment interruptions and a poor quality of life. Although spouses/partners can help by encouraging patient self-management (eg, self-care) during RT, they often experience high psychological distress rates, lack basic health care knowledge and skills, and report increased marital conflict regarding patient self-management. The current pilot study examined the feasibility and acceptability of a 6-session telephone-based intervention called Spouses coping with the Head And neck Radiation Experience (SHARE), which teaches self-management, communication, and coping skills to patients with HNC and their spouses.

Gestational Age at Arrest of Development: An Alternative Approach for Assigning Time at Risk in Studies of Time-Varying Exposures and Miscarriage.

Am J Epidemiol 2018 Dec 6. Epub 2018 Dec 6.

Vanderbilt Epidemiology Center, Institute for Medicine and Public Health, Vanderbilt University Medical Center, Nashville, Tennessee.

Time between arrest of pregnancy development and miscarriage represents a window in which pregnancy is nonviable and not developing. In effect, the loss has happened and exposures cannot influence its fate. However, epidemiologic studies of miscarriage traditionally use gestational age at miscarriage to assign time in survival analyses, which overestimates duration of exposure and time at risk.

Role of epithelial-to-mesenchymal transition in inflammatory bowel disease.

J Crohns Colitis 2018 Dec 6. Epub 2018 Dec 6.

IBD Center, Department of Gastroenterology, Humanitas Research Hospital, Rozzano, Milan, Italy.

Intestinal fibrosis is an inevitable complication in patients with inflammatory bowel disease (IBD), occurring in its two major clinical manifestations: ulcerative colitis and Crohn's disease. Fibrosis represents the final outcome of the host reaction to persistent inflammation which triggers a prolonged wound healing response resulting in the excessive deposition of extracellular matrix, eventually leading to intestinal dysfunction. The process of epithelial-to-mesenchymal transition (EMT) represents an embryonic program relaunched during wound healing, fibrosis and cancer. Read More

The HTN3-MSANTD3 Fusion Gene Defines a Subset of Acinic Cell Carcinoma of the Salivary Gland.

Am J Surg Pathol 2018 Dec 4. Epub 2018 Dec 4.

Department of Pathology, Stanford University School of Medicine, Stanford, CA.

The spectrum of tumors arising in the salivary glands is wide and has recently been shown to harbor a network of tumor-specific fusion genes. Acinic cell carcinoma (AciCC) is one of the more frequently encountered types of salivary gland carcinoma, but it has remained a genetic orphan until recently when a fusion between the HTN3 and MSANTD3 genes was described in one case. Neither of these 2 genes is known to be implicated in any other malignancy. Read More

Spiteful and contemptuous: A new look at the emotional experiences related to psychopathy.

Personal Disord 2018 Dec 6. Epub 2018 Dec 6.

Department of Psychiatry, University of California, San Diego.

Psychopathy has long been conceptualized in terms of an absence of emotion. Yet, recent studies have suggested that the experience of other-directed negative emotions may be more intimately linked to psychopathy than previously acknowledged, although there is limited knowledge concerning the experience of such emotions. The present study examined the disposition to experience two other-directed emotions, spitefulness and contempt, that are conceptually linked with psychopathy but currently are limited in empirical support.
