By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Development of novel biliary metal stent with coil-spring structure and its application in vivo swine biliary stricture model

open access: yesFrontiers in Oncology, 2023
BackgroundAs of date, endoscopic biliary stenting with plastic stent (PS) and self-expandable metal stent (SEMS) have been widely used for the palliation of biliary tract strictures.

Response of Sunflower Yield and Phytohormonal Changes to Azotobacter,Azospirillum,Pseudomonas and Animal Manure in a Chemical Free Agroecosystem [PDF]

open access: yes, 2011
There are new trends in agriculture to move toward the low input systems with the lower application of chemical fertilizers. To reach this goal, different methods, such as the application of biofertilizers, may be used.

A bottom–up model of spatial attention predicts human error patterns in rapid scene recognition [PDF]

open access: yes, 2007
Humans demonstrate a peculiar ability to detect complex targets in rapidly presented natural scenes. Recent studies suggest that (nearly) no focal attention is required for overall performance in such tasks.

Hyperoxia increases ventilator-induced lung injury via mitogen-activated protein kinases: a prospective, controlled animal experiment

open access: yesCritical Care, 2007
IntroductionLarge-tidal volume (VT) mechanical ventilation and hyperoxia used in patients with acute respiratory distress syndrome can damage pulmonary epithelial cells through lung inflammation and apoptotic cell death.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Animalexperiment on regulating effect of stored red blood cells transfusion on BMDMs in inflammatory conditions

open access: yesZhongguo shuxue zazhi, 2023
Objective To discuss the regulating effect of stored red blood cells (RBCs) transfusion on BMDMs in inflammatory conditions, and the relationship between stored RBCs transfusion and inflammatory response induced by bacterial infection.

Networks learn from learning histories [PDF]

open access: yes, 2011
The research programme Networks in Animal Husbandry began in 2004 without any concrete final objectives. The programme did have to contribute in all sorts of ways: by making “knowledge from the shelf” applicable, to making animal farming more robust ...

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...
