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.

A mobile app that uses neurofeedback and multi-sensory learning methods improves reading abilities in dyslexia: A pilot study.

Appl Neuropsychol Child 2021 Apr 16:1-11. Epub 2021 Apr 16.

Department of Electrical and Computer Engineering, University of Rochester, Rochester, NY, USA.

Reading comprehension is difficult to improve for children with dyslexia because of the continuing demands of orthographic decoding in combination with limited working memory capacity. Children with dyslexia get special education that improves spelling, phonemic and vocabulary awareness, however the latest research indicated that special education does not improve reading comprehension. With the aim of improving reading comprehension, reading speed and all other reading abilities of children with dyslexia, Auto Train Brain that is a novel mobile app using neurofeedback and multi-sensory learning methods was developed.

Using WhatsApp messenger for health systems research: a scoping review of available literature.

Health Policy Plan 2021 Apr 16. Epub 2021 Apr 16.

The African Centre for Migration & Society (ACMS), University of the Witwatersrand (Wits), Solomon Mahlangu House, Braamfontein Campus East, Private Bag 3, Johannesburg 2000, South Africa.

Globally, the use of mobile phones for improving access to healthcare and conducting health research has gained traction in recent years as rates of ownership increase, particularly in low- and middle-income countries (LMICs). Mobile instant messaging applications, including WhatsApp Messenger, provide new and affordable opportunities for health research across time and place, potentially addressing the challenges of maintaining contact and participation involved in research with migrant and mobile populations, for example. However, little is known about the opportunities and challenges associated with the use of WhatsApp as a tool for health research. Read More

Prompting a Fresh Start for Adults With Food Insecurity and Increased BMI: A Case Series of Four Patients in a Food Prescription Program.

Cureus 2021 Mar 12;13(3):e13857. Epub 2021 Mar 12.

Humanities, Health, and Society/Family Medicine, Florida International University, Herbert Wertheim College of Medicine, Miami, USA.

Estimates place low intake of fruits and vegetables, physical inactivity, and high BMI (overweight-obesity) as all in the top 12 causes of death. Food and dietary education are becoming a focus in how we approach disease prevention and management, and food prescription programs in particular are showing promise, especially in under-resourced, food-insecure communities. This paper describes a pilot food prescription program in a handful of uninsured patients enrolled in an interprofessional clinical and educational program of a medical school in South Florida.

The Moderating Effects of Emotions on the Relationship Between Self-Reported Individual Traits and Actual Risky Driving Behaviors.

Psychol Res Behav Manag 2021 9;14:423-447. Epub 2021 Apr 9.

School of Transportation and Vehicle Engineering, Shandong University of Technology, Zibo, Shandong Province, People's Republic of China.

Purpose: Researches addressing driving behaviors have not fully revealed how emotions affect risky driving behaviors and tend to focus on the effects of some negative emotions rather than those of more specific emotions. This study aimed to test the potential moderating effects of eight common driving emotions on the relationship between self-reported individual traits (sensation seeking and driving style) and actual risky driving behaviors, sequentially providing some implications for the risky driving behavior prevention.

Participants And Methods: A total of 78 licensed drivers were recruited from undergraduate students, company employees and taxi drivers in China. Read More
