Reduced corrosion of Zn alloy by HA nanorods for enhancing early bone regeneration.

Zinc alloys have emerged as promising materials for bone regeneration due to their moderate biodegradation rates. However, the blast release of Zn from Zn alloy substrates affects cell behaviors and the subsequent osseointegration quality, retarding their early service performance. To address this issue, extracellular matrix-like hydroxyapatite (HA) nanorods were prepared on Zn-1Ca (ZN) by a combined hydrothermal treatment (HT).

The acceptance and hesitancy of COVID-19 vaccination among chronic obstructive pulmonary disease (COPD) patients.

Severe acute respiratory syndrome coronavirus 2, which is responsible for the coronavirus disease 2019 (COVID-19), causes severe clinical outcomes in old individuals and patients with underlying diseases, including chronic obstructive pulmonary disease (COPD). Considering vaccination is still the most effective method to prevent COVID-19-associated death, it is imperative to evaluate COPD patients' attitudes toward the COVID-19 vaccine. This cross-sectional design study was conducted to assess vaccine acceptance and hesitancy among 212 COPD patients who attended the outpatient department from January 1, 2021, to July 31, 2022.

The function of S100A4 in pulmonary disease: A review.

S100 protein family, which represents 25 relatively small calcium binding proteins, is involved in many intracellular and/or extracellular processes, including differentiation, apoptosis, migration/invasion, Ca2+ homeostasis, inflammation, and tissue repair. As an important member, S100A4 was reported to have an abnormal expression in several lung diseases, such as lung cancer, pulmonary hypertension, idiopathic pulmonary fibrosis (IPF), etc. For example, in lung cancer, S100A4 was demonstrated to be associated to metastatic tumor progression and epithelial to mesenchymal transition (EMT).
