Gene autoregulation by 3’ UTR-derived bacterial small RNAs

eLife, 2020
Negative feedback regulation, that is the ability of a gene to repress its own synthesis, is the most abundant regulatory motif known to biology. Frequently reported for transcriptional regulators, negative feedback control relies on binding of a ...

Autoregulation of Hepatic Circulation

Japanese Heart Journal, 1966
(1) The pressure-flow relations in both the hepatic artery and the portal vein system were investigated in a total of 13 dog livers, perfused with the homologous blood by a pump oxygenator. In addition, the interaction between the hepatic artery and the portal vein system was also studied.

Dysregulation of U12‐Type Splicing in Lupus Neutrophils

Arthritis &Rheumatology, Accepted Article.
Abstract. Objective Neutrophil dysfunction is a hallmark of systemic lupus erythematosus (SLE), but its molecular basis remains unclear. This study explores transcriptional and post‐transcriptional changes in low‐density granulocytes (LDGs), a proinflammatory neutrophil subset expanded in SLE, focusing on NADPH oxidase (Nox) function and minor intron ...

Identification of Three Type II Toxin-Antitoxin Systems in Streptococcus suis Serotype 2

Toxins, 2018
Type II toxin-antitoxin (TA) systems are highly prevalent in bacterial genomes and have been extensively studied. These modules involve in the formation of persistence cells, the biofilm formation, and stress resistance, which might play key roles in ...

Regulation of Blood Flow in the Cerebral Posterior Circulation by Parasympathetic Nerve Fibers: Physiological Background and Possible Clinical Implications in Patients With Vertebrobasilar Stroke

Frontiers in Neurology, 2021
Posterior circulation involves the vertebrobasilar arteries, which supply oxygen and glucose to vital human brainstem structures and other areas. This complex circulatory- perfusion system is not homogenous throughout the day; rather, its hemodynamic ...

Bilateral Transcranial Doppler Monitoring During Neonatal Cardiac Surgery; Guidance for Clinical and Scientific Use

Pediatric Anesthesia, EarlyView.
ABSTRACT Introduction Neonates undergoing cardiac surgery face a high risk of neurological injury and neurodevelopmental complications. Transcranial Doppler monitoring is used and validated in adults to measure cerebral blood flow and can provide valuable insights into cerebral perfusion in neonates.

Prediction of poor prognosis using the peak systolic velocity and early diastolic velocity of the central retinal artery in patients with post‐cardiac arrest syndrome

Hong Kong Journal of Emergency Medicine
Introduction Monitoring intracranial pressure (ICP) in patients with post‐cardiac arrest syndrome (PCAS) is crucial for effective management and prognosis assessment. However, continuous ICP monitoring is rarely practiced.
