Hot Water Preparation along with Combined Solar Thermochemical Energy Storage System: Experimental Validation and Performance Simulation

Received: 18 December 2020;  Published: 14 April 2021;  doi: 10.21926/jept.2102017

Abstract

Hybrid solar thermal systems are considered to be a promising solution for delivering clean thermal energy for the building sector, especially while combining them with other renewable energy sources. Usually, solar energy production does not match the thermal energy demand, and hence the energy storage must be integrated. Thermochemical energy storage is adapted particularly to be used along with solar thermal applications. In this article, the design of the combined solar thermochemical energy storage system is p [...]

Association between Sleep Deprivation and Metformin Treatment on Pancreatic and Liver Function in Mice

Received: 10 March 2020;  Published: 18 May 2020;  doi: 10.21926/obm.hg.2002047

Abstract

Metformin has been widely used as a therapeutic drug for hyperglycemia and diabetes. Sleep is a vital and restorative process that is necessary for the proper functioning of organs. Sleep deprivation can induce multi-organ injury, including damage to the pancreas and liver that may result in hyperglycemia and diabetes. We studied the role of metformin in reversing sleep deprivation-induced hyperglycemia and pancreatic and liver dysfunction in mice. Mice were kept in cages and fed water and food ad libitum. Mice wer [...]

Molecular Genetic Study on VNTR-polymorphism of Two Cytokine Genes Antagonist of the Receptor of Interleukin 1 (rs2234663) and Interleukin 4 (rs8179190) Associated with Dental Caries in Children

Received: 24 December 2021;  Published: 27 June 2022;  doi: 10.21926/obm.genet.2202158

Abstract

In this study, we investigated VNTR polymorphisms in intron 2 of the IL1RN gene (rs2234663) and intron 3 of the IL4 gene (rs8179190) related to the development of caries in school children (N = 196) with mixed bite dentition from Krasnodarskii Krai. The genotypes A1/A1 and L/L (L-"long" alleles) (rs2234663) provided resistance to the most intensive form of dental caries. The groups of children with DFC (decompensated form of caries) were significantly different from the pooled group SFC (subcompensated form of cari [...]

A New Chiral Cyclopalladated Ferrocenylimine Self-assembly Polymeric Film supported on Silicon for Heck and Suzuki-coupling Reactions

Received: 21 March 2022;  Published: 14 April 2022;  doi: 10.21926/cr.2202010

Abstract

A new chiral cyclopalladated ferrocenyl imine catalyst (called 4a2) was designed and synthesized, and its self-assembly catalytic polymeric brush supported on silicon (denoted as Si@PB4a2) was also fabricated by surface-initiated atom transfer radical polymerization (ATRP) and characterized. The catalytic properties of monomer 4a2 in homogeneous and Si@PB4a2 in heterogeneous in Heck and Suzuki cross-coupling were investigated, respectively. They exhibited higher catalytic activity in Heck, and Suzuki coupling react [...]

Traffic NOx Pollution Prediction and Health Cost Estimation Using Machine Learning: A Case Study of Toronto, Canada

Received: 11 March 2022;  Published: 25 December 2022;  doi: 10.21926/jept.2204043

Abstract

Road traffic is a significant source of air pollution that has a harmful impact on human health. To reduce the health and environmental impacts of fossil fuel consumption in the transportation sector, many countries have implemented policies to promote the deployment of electric vehicles (EVs). A vital factor to consider when designing policies to support EV use is the monetized health impacts of fossil fuel consumption. This research aims to investigate the health benefit of replacing internal combustion engine ve [...]

Impact of SARS-CoV-2 Outbreak on Physical and Mental Health, Psychological Distress, and Suicidal Ideation, and the Mediating Role of Stressors

Received: 23 December 2020;  Published: 17 March 2021;  doi: 10.21926/obm.icm.2101010

Abstract

This study investigated the physical and psychological impacts of elements related to coronavirus disease (COVID-19) and demographic data in Japan both directly and as mediated by stressors, immediately following the rescinding of the state of emergency declaration accompanying the severe acute respiratory syndrome coronavirus 2 outbreak. An online survey was administered to 1,500 Japanese registered with an online outsourcing service. Data were analyzed with structural equation modeling using Mplus. Relatively lar [...]

Food Insecurity, Cardiometabolic Risk and Cardiovascular Disease: A Narrative Review and Call for Action

Received: 24 September 2023;  Published: 09 January 2024;  doi: 10.21926/obm.icm.2401006

Abstract

Food insecurity and insufficient access to affordable nutrition have been associated with increased risk for the development of multiple chronic medical conditions, including cardiovascular disease. In this narrative review, we explore the association between food insecurity and the development of chronic medical conditions that confer increased cardiometabolic risk, cardiovascular disease, and mortality. We also identify the various barriers leading to food insecurity and lack of food literacy, with an emphasis on [...]

Therapeutic Strategies and Current Management for Hepatic Encephalopathy in Liver Cirrhosis

Received: 04 February 2019;  Published: 16 July 2019;  doi: 10.21926/obm.hg.1903027

Abstract

Hepatic encephalopathy (HE) is a neuropsychiatric syndrome showing a wide spectrum and one of the serious complications seen in patients with acute and chronic liver disease or spontaneous portal-systemic shunting. Recently, HE has been classified into two categories: covert HE, which involves minimal HE and is identified solely through psychometric or neurological tests, and overt HE (coma grade II-IV). Although recent therapies based on evidence-based results have improved the therapeutic outcomes of HE patients, [...]

Perspective on Neurobiological and Clinical Early Indicators of Mild Cognitive Decline and Alzheimer’s Disease

Received: 17 April 2017;  Published: 09 July 2017;  doi: 10.21926/obm.neurobiol.1702006

Abstract

There is a need for early diagnosis, monitoring and treatment of Alzheimer’s Disease (AD) and Mild Cognitive Impairment (MCI). Traditional assessments of cognitive decline have been found to lack sensitivity and accuracy in differentiating varying stages of Dementia and cognitive decline as well as being time consuming in their administration. Key components of cognition namely memory and executive function have been identified as most predicative of AD status. Brief cognitive screening tools such as the Montreal C [...]
