Distribution and activity of nitrate and nitrite reductases in the microbiota of the human intestinal tract

open access: yesThe FEBS Journal, EarlyView.
Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...

The fc fragment of IgMs binds C1q to activate the first step of the classical complement pathway, while inhibiting complement‐dependent cytotoxicity

open access: yesThe FEBS Journal, EarlyView.
Multimeric IgM‐fragment crystallizable region (Fc) fragments retain the ability to bind C1q and initiate the classical complement pathway, leading to C4 activation and deposition in vitro. However, the Fc cores can also inhibit complement‐dependent cytotoxicity by competing with surface‐bound antibodies for C1q engagement.

Role of a Deep‐Learning Based Convolutional Neural Network Model for Real‐Time Ventricular Tachycardia Alarm Classification

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
Our manuscript discusses the role of a Convolutional Neural network based Deep‐learning model for the classification of ventricular tachycardia alarms. Our algorithm based on input from multiple raw waveform inputs, including electrocardiogram leads, photoplethysmogram, and arterial blood pressure signals achieved a good degree of accuracy and ...

Second Asian Consensus Report on Functional Dyspepsia (2025): Updated Recommendations

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background Functional dyspepsia (FD) is a common gastrointestinal disorder that significantly impacts patients' quality of life. Over a decade ago, the Asian Neurogastroenterology and Motility Association (ANMA) and the Asian Pacific Association of Gastroenterology (APAGE) jointly developed the first Asian consensus report on FD.
