Endocytosis of peroxiredoxin 1 links sterile inflammation to immunoparalysis in pediatric patients following cardiopulmonary bypass.

Redox Biol 2021 Jul 28;46:102086. Epub 2021 Jul 28.

Graduate Institute of Clinical Medicine, College of Medicine, National Taiwan University, Taipei, Taiwan; Department of Internal Medicine, National Taiwan University Hospital, Taiwan; Center of Precision Medicine, College of Medicine, National Taiwan University, Taiwan. Electronic address:

After cardiopulmonary bypass (CPB), the occurrence of systemic inflammatory response is often accompanied by a persistent compensatory anti-inflammatory response syndrome that can lead to a compromised immune competence termed immunoparalysis, rendering the patients susceptible to infections which is a leading complication following cardiac surgery. However, the underlying mechanisms of CPB-elicited immunoparalysis remain obscure. In this study we showed that peroxiredoxin 1 (Prdx1), a putative cytosolic antioxidant, was released immediately after CPB in a cohort of pediatric patients receiving congenital cardiac surgery.

Endoscopic Evaluation and Management of Late Complications After Bariatric Surgery: a Narrative Review.

Obes Surg 2021 Jul 30. Epub 2021 Jul 30.

The Center for the Treatment of Obesity and Diabetes, Hospital Oswaldo Cruz, Sao Paulo, Brazil.

Despite ongoing evolution in technique and a low mortality rate, clinicians may care for patients who suffer late complications (> 90 days of surgery) after bariatric surgery. Endoscopic techniques are used to identify and manage many of the late complications of the two most commonly performed bariatric surgeries: sleeve gastrectomy and Roux-en-Y gastric bypass. Stenosis at the incisura angularis and gastroesophageal reflux disease may occur in patients who have undergone a sleeve gastrectomy. Read More

Tyrosine-Templated Dual-Component Silver Nanomaterials Exhibit Photoluminescence and Versatile Antimicrobial Properties through ROS Generation.

ACS Appl Mater Interfaces 2021 Jul 30. Epub 2021 Jul 30.

Department of Chemistry, Indian Institute of Science Education and Research Bhopal, Bhopal Bypass Road, Bhopal 462066, Madhya Pradesh, India.

The role of small molecules in the preparation of metal nanomaterials generates considerable interest in the fields from materials science to interdisciplinary sciences. In this study, a small amino acid, l-tyrosine (Tyr), has been used as a ligand precursor for the preparation of silver nanomaterials (AgNMs) comprising a dual system: smaller silver nanoclusters (responsible exclusively for the photophysical properties) and larger silver nanoparticles (responsible exclusively for the antimicrobial properties). The luminescent properties of this AgNM system substantiate the role played by Tyr as a capping and a reducing agent outside the protein environment. Read More
