Increased DNA damage in blood cells of rat treated with lead as assessed by comet assay [PDF]

open access: yesBangladesh Journal of Pharmacology, 2008
A growing body of evidence suggests that oxidative stress is the key player in the pathogenesis of lead-induced toxicity. The present study investigated lead induced oxidative DNA damage, if any in rat blood cells by alkaline comet assay.

Beyond the GTP‐cap: Elucidating the molecular mechanisms of microtubule catastrophe

open access: yesBioEssays, Volume 45, Issue 1, January 2023., 2023
Microtubule dynamics are essential for myriad cellular processes. The switching between microtubule growth and shrinkage is traditionally explained by the loss of a protective “cap” of GTP‐bound tubulin subunits from the growing microtubule end. New research shows that features beyond the nucleotide content at the growing end impact microtubule ...

Linalool attenuated ischemic injury in PC12 cells through inhibition of caspase‐3 and caspase‐9 during apoptosis

open access: yesFood Science &Nutrition, Volume 11, Issue 1, Page 249-260, January 2023., 2023
This study indicated, for the first time, that (±) linalool and its enantiomer, (R)‐(‐) linalool protected PC12 cells against injury induced by oxygen and glucose deprivation/reoxygenation (OGD/R) via the mitigation of oxidative stress and the downregulation of Bax/Bcl‐2, caspase‐3 and caspase‐9, resulting in decreased apoptotic cell death.

Beyond prediction: Off‐target uses of artificial intelligence‐based predictive analytics in a learning health system

open access: yesLearning Health Systems, Volume 7, Issue 1, January 2023., 2023
Abstract Introduction Artificial‐intelligence (AI)‐based predictive analytics provide new opportunities to leverage rich sources of continuous data to improve patient care through early warning of the risk of clinical deterioration and improved situational awareness.Part of the success of predictive analytic implementation relies on integration of the ...

Experimental validation of non‐Newtonian stratified co‐extrusion prediction models using a digital process twin

open access: yesPolymer Engineering &Science, Volume 62, Issue 12, Page 3902-3922, December 2022., 2022
Workflow of the experimental study for validating non‐Newtonian co‐extrusion flow models: digital twin of the co‐extrusion process based on symbolic regression models, design of experiments, and error analysis Abstract In the co‐extrusion of plastics, pressure‐throughput behavior, layer distribution, and residence time are crucial parameters, modeling ...

Comet assay - a sensitive tool for genotoxicity assessment of environmental stress in Mytilus galloprovincialis from the Bulgarian Black Sea coast [PDF]

open access: yesBioDiscovery, 2017
Assessment of DNA damage is of primary concern when the pollution-related stress in living organisms has to be determined. The reason for this concern comes from the evidence that damages in DNA often lead to mutations which are potential threat for the ...

German guideline diverticular disease/diverticulitis

open access: yesUnited European Gastroenterology Journal, Volume 10, Issue 9, Page 923-939, November 2022., 2022
Abstract Diverticulosis and diverticular disease are ranked among the most common gastroenterological diseases and conditions. While for many years diverticulitis was found to be mainly an event occurring in the elder population, more recent work in epidemiology demonstrates increasing frequency in younger subjects.
