Comparative study of HSO/SO versus HPO functionalities anchored on TiO-supported antimony oxide-vanadium oxide-cerium oxide composites for low-temperature NO activation.

J Hazard Mater 2021 Apr 6;416:125780. Epub 2021 Apr 6.

Extreme Materials Research Center, Korea Institute of Science and Technology, Seoul 02792, South Korea. Electronic address:

TiO-supported antimony oxide-vanadium oxide-cerium oxide (SVC) imparts Lewis acidic (L)/Brönsted acidic (B) sites, labile (O)/mobile oxygens (O), and oxygen vacancies (O) for selective catalytic NO reduction (SCR). However, these species are harmonious occasionally, readily poisoned by HO/sulfur/phosphorus/carbon, thus limiting SCR performance of SVC. Herein, a synthetic means is reported for immobilizing HSO/SO (A= 3-4) or HPO (B= 1-3) on the L sites of SVC to form SVC-S and SVC-P. Read More

Galanin and prolactin expression in relation to parental care in two sympatric cichlid species from Lake Tanganyika.

Gen Comp Endocrinol 2021 Apr 13:113785. Epub 2021 Apr 13.

Konrad Lorenz Institute of Ethology, Department of Interdisciplinary Life Sciences, University of Veterinary Medicine Vienna, Austria.

Our understanding of the hormonal mechanisms underlying parental care mainly stems from research on species with uniparental care. Far less is known about the physiological changes underlying motherhood and fatherhood in biparental caring species. Here, using two biparental caring cichlid species (Neolamprologus caudopunctatus and Neolamprologus pulcher), we explored the relative gene-expression levels of two genes implicated in the control of parental care, galanin (gal) and prolactin (prl).

Results from a malaria indicator survey highlight the importance of routine data capture in high-risk forest and farm transmission sites in Vietnam to tailor location-specific malaria elimination interventions.

PLoS One 2021 16;16(4):e0250045. Epub 2021 Apr 16.

United States Naval Medical Research Unit TWO, Singapore.

In-line with the World Health Organization's (WHO) Global Technical Strategy for Malaria (2016-2030), Vietnam is striving to eliminate malaria by 2030. Targeting appropriate interventions in high-risk populations such as forest and forest-fringe communities is a critical component of malaria elimination efforts in Vietnam. In 2016, a household-level malaria indicator survey was conducted in Phu Yen Province, Vietnam with the aim of assessing the knowledge, behaviors and associated risks of malaria infection among priority mobile and migrant populations (MMPs) working and sleeping in forests and on farms.

Radiographics 2021 Apr 16:200160. Epub 2021 Apr 16.

From the Department of Medical Imaging, The Ottawa Hospital, University of Ottawa, 1053 Carling Ave, Ottawa, ON, Canada K1H 1H6 (N.S.); Departments of Radiology (M.S.D., N.E.C.) and Urology (M.S.D.), Michigan Medicine, University of Michigan, Ann Arbor, Mich; Joint Department of Medical Imaging, University Health Network, Mount Sinai Hospital and Women's College Hospital, University of Toronto, Toronto, ON, Canada (S.K.); Department of Radiology, University of Nebraska Medical Center, Omaha, Neb (E.A.E.); Department of Radiology, University of Texas Southwestern Medical Center, Dallas, Tex (I.P.); Department of Radiology, New York University Langone Medical Center, New York, NY (N.H.); Department of Radiology and Diagnostic Imaging, Hospital Israelita Albert Einstein, São Paulo, Brazil (R.H.B.); Department of Radiology, Brigham and Women's Hospital/Dana-Farber Cancer Institute, Harvard Medical School, Boston, Mass (A.S.); and Department of Radiology, Brigham and Women's Hospital, Harvard Medical School, Boston, Mass (S.G.S.).

Cystic renal masses are commonly encountered in clinical practice. In 2019, the Bosniak classification of cystic renal masses, originally developed for CT, underwent a major revision to incorporate MRI and is referred to as the Bosniak Classification, version 2019. The proposed changes attempt to define renal masses (ie, cystic tumors with less than 25% enhancing tissue) to which the classification should be applied; emphasize specificity for diagnosis of cystic renal cancers, thereby decreasing the number of benign and indolent cystic masses that are unnecessarily treated or imaged further; improve interobserver agreement by defining imaging features, terms, and classes of cystic renal masses; reduce variation in reported malignancy rates for each of the Bosniak classes; incorporate MRI and to some extent US; and be applicable to all cystic renal masses encountered in clinical practice, including those that had been considered indeterminate with the original classification.

Mobile Health Intervention Promoting Physical Activity in Adults Post Cardiac Rehabilitation: Pilot Randomized Controlled Trial.

JMIR Form Res 2021 Apr 16;5(4):e20468. Epub 2021 Apr 16.

Departments of Medicine and Epidemiology & Biostatistics, University of California San Francisco, San Francisco, CA, United States.

Background: Cardiac rehabilitation (CR) is an exercise-based program prescribed after cardiac events associated with improved physical, mental, and social functioning; however, many patients return to a sedentary lifestyle leading to deteriorating functional capacity after discharge from CR. Physical activity (PA) is critical to avoid recurrence of cardiac events and mortality and maintain functional capacity. Leveraging mobile health (mHealth) strategies to increase adherence to PA is a promising approach. Read More
