Deficient neutrophil responses early in influenza infection promote viral replication and pulmonary inflammation.

Neutrophils play key protective roles in influenza infections, yet excessive neutrophilic inflammation is a hallmark of acute lung injury during severe infections. Phenotypic heterogeneity is increasingly recognized in neutrophil populations; however, how functional variation in neutrophils between individuals determine the diverse outcomes of influenza remains unclear. To examine immunologic responses that may drive varying outcomes in influenza, we infected C57BL/6 (B6) and A/J mice with mouse-adapted influenza A virus A/PR/8/34 H1N1.

Cytokinins are plant hormones that regulate cell growth and differentiation. In particular, zeatin (ZTN) delays cellular senescence of human fibroblasts and keratinocytes and exhibits anticancer activity. Chemotherapy-induced anemia is a major side effect of anticancer therapy secondary to premature senescence of red blood cells (RBCs).

Introduction: Acute kidney injury (AKI) is a common complication of acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome (MODS) in patients receiving extracorporeal membrane oxygenation (ECMO) support, leading to requirement of continuous renal replacement therapy (CRRT) in 70% of ECMO patients. Parallel arrangement of CRRT and ECMO circuits is common in adult patients. However, CRRT may also be integrated directly into the ECMO circuit.

In the background of antioxidation properties of selenium (Se) in plants, the role of nano‑selenium (Se-NPs) was justified in the modulation of Capsicum fruit ripening. In our study, exogenous application of 8 mg L Se-NPs on fruits through 7 days (D) of postharvest storage regulated decay rate, water loss and fruit coat firmness. Se-NPs recovered fruit coat damages with reduction of ion leakage, lipid oxidation, and accumulation of polyamines.

Calcium ions (Ca) are important second messengers and are known to participate in cold signal transduction. In the current study, we characterized a Ca-binding protein gene, VamCP1, from the extremely cold-tolerant grape species Vitis amurensis. VamCP1 expression varied among organs but was highest in leaves following cold treatment, peaking 24 h after treatment onset.
