by Shayesta Islam, Haleema Bano, Asif Aziz Malik, Fahad Alotaibi

Landfills are the most affordable and popular method for managing waste in many parts of the world, However, in most developing nations, including India, the infiltration of hazardous materials from improperly managed dumping site continues to be a significant environmental problem. Around the world, leachate is a significant point source of contamination in numerous environmental media, including soil, groundwater, and surface water. Читать дальше...

Computational investigation of missense somatic mutations in cancer and potential links to pH-dependence and proteostasis

Plos.org 

by Shalaw Sallah, Jim Warwicker

Metabolic changes during tumour development lead to acidification of the extracellular environment and a smaller increase of intracellular pH. Searches for somatic missense mutations that could reveal adaptation to altered pH have focussed on arginine to histidine changes, part of a general arginine depletion that originates from DNA mutational mechanisms. Analysis of mutations to histidine, potentially a simple route to the introduction of pH-sensing, shows... Читать дальше...

Method for detection of cerebral blood flow in neurointensive care using longitudinal arterial spin labeling MRI

Plos.org 

by Sofie Tapper, Anders Tisell, Jan Hillman, Karin Wårdell

Cerebral blood flow (CBF) is carefully monitored in the Neurointensive Care Unit (NICU) to prevent secondary brain insults in patients who have suffered subarachnoid hemorrhage. Including absolute MRI measurements of CBF in the NICU monitoring protocol could add valuable information and potentially improve patient outcomes. This is particularly feasible at Linköping University Hospital, which uniquely has an MRI scanner located in the NICU... Читать дальше...

Zinc utilisation, trends, and predictors among under-five children with diarrhoea in Ethiopia: A pooled analysis

Plos.org 

by Girma Beressa

Zinc has a significant benefit in saving children’s lives. It decreases severity, diarrhoeal duration, and death rates. However, evidence on zinc utilisation, trends, and predictors among under-five children with diarrhoea in Ethiopia was sparse and inconclusive. This study aimed to assess the pooled zinc utilisation, trends, and predictors among under-five children with diarrhoea in Ethiopia. This study used Ethiopian demographic and health survey (EDHS-2005–2016) data with... Читать дальше...
