One major cause of aquatic pollution is the accumulation of heavy metal ions. This study shows the biosorption properties of orange peel for removing chromium (CrVI) from industrial wastewater at a laboratory scale. This study focused on the biosorption of CrVI using orange peel biosorbent (OPB) from aqueous solutions in the plastic industry (PI), textile and fabrics industry (TFI), chemical industry (CI), and food industry (FI). The total Cr contents in effluents of FI, CI, TFI and PI varied between 30.0-38.0, 23. [...]

This study reviews the biochemical mechanisms and clinical implications of N-heterocyclic amine drugs, particularly in the context of pain management, mental health, and opioid withdrawal. It highlights the structural diversity and receptor binding capabilities of these compounds, which enable them to target the nervous system and cross the blood-brain barrier effectively. The article discusses the role of opioids in pain relief, detailing their agonistic effects on opioid receptors and the subsequent risk of addic [...]

The pandemic has shown its effect on the world regarding health, economy, society, and environment. Whether it is a negative or positive impact, the period of this pandemic has a vast open platform for further studies. This review focused on the impact of the COVID-19 pandemic lockdown on water quality. It is hypothesized that due to the reduced amount of anthropogenic activity due to the global lockdown, the water quality of water resources increased and rejuvenated. This review showed the study period, methods an [...]

An early formation tester operating a “sink probe” that extracts fluids from the borehole, also measures pressures at its location; pressures are additionally collected at two passive sensors, one situated 180 deg away and the second about meter axially. These positions are not conducive to accurate permeability predictions, since pressure transient signals used for inverse analysis attenuate very rapidly. Closer probe spacings offer formation evaluation advantages at low mobilities because Darcy pressure dissipati [...]

YNCRG is a combination of five traditional Chinese ingredients with medicinal properties. We studied its effects and mechanism of action on a rat model of non-alcoholic fatty liver with metabolic syndrome. Eight-week-old male SHRcp rat(s) and Wister Kyoto (WKY) rats were adaptively fed for one week, after which they were randomly divided into three groups, including the control group (n = 9), the YNCRG group (n = 8), and the WKY group (n = 8). The WKY group could freely consume water, the control group was provided [...]

Physical activity is essential to delaying cognitive decline and preventing cognitive impairment in older adults. We designed and implemented two-level 4Active intervention for older adults living in retirement communities. This study aimed to examine the effectiveness of the 4Active intervention in increasing physical activity and cognitive function in older adults. Fifty-eight eligible older adults with a mean age of 83.83 years (76.3% females) living in two retirement communities voluntarily participated in this [...]

This editorial briefly describes possible relationships and similarities between chess and acupuncture. Although the methods of chess and acupuncture could not be more different, possible joint effects on the brain can be hypothesized. However, the effectiveness of these joint effects has yet to be proven in scientific studies. Both chess and acupuncture can be used to improve physical and mental well-being. According to the author, the Yintang point could play a key role here.

The work of psychotherapy demands much of those who engage in it. Compassion provisioned by therapists requires varying competencies, yet remains a highly embodied and enactive endeavour. Therapist skill can be cultivated in this area and enhanced through a variety of body-mind trainings, including various forms of therapist personal practice. However, much clinical training/continued professional development centres on education workshops, emphasising knowledge above skill. Given this we present feasibility data f [...]

The 2014 Pancreas Allocation System established national qualifying criteria for simultaneous kidney pancreas (SPK) transplantation. The 2019 UNOS Pancreas Transplantation Committee Policy 11.3.B modified these guidelines to expand transplantation. Subsequent effects on recipient demographics have not been studied. We analyzed 81 SPK transplantations performed at our center from June 2014 to December 2020 to compare recipient demographics and outcomes before and after the 11.3.B policy change. National data were al [...]

This systematic review examined the impact of wellbeing interventions on the anxiety levels of children attending low-income schools. Studies, published between January 2000 and April 2022, were included if they had samples of school aged children attending low-income schools who were given a universal school-based wellbeing intervention. Ten databases were searched systematically to identify 542 records. After title and abstract screening, 43 records remained for full text screening, and of these studies, 10 met i [...]
