Hand-assisted sputum excretion can effectively reduce postoperative pulmonary complications of esophageal cancer.

Background: This study explores whether postoperative hand-assisted expectoration can reduce postoperative pulmonary complications (PPCs) in patients with esophageal cancer.

Methods: A retrospective analysis was performed on 543 patients undergoing radical esophageal cancer (EC) surgery in our hospital from October 2018 to August 2019, 156 of whom received postoperative handassisted sputum excretion (pulmonary rehabilitation, PR) and 387 of whom who did not receive postoperative hand-assisted sputum excretion (no pulmonary rehabilitation, NPR). Because the clinical characteristics of the two groups were not balanced, we used propensity score matching (PSM) to account for the variable factors of age, gender, body mass index (BMI), chronic respiratory comorbidity, smoking index, operation time, operation method, pathological stage.

Evaluation of the Structure and Biological Activities of Condensed Tannins from Acanthus ilicifolius Linn and Their Effect on Fresh-Cut Fuji Apples.

Condensed tannins (CT) have been isolated and purified from leaves of Acanthus ilicifolius Linn. And their structures were investigated by three methods: C nuclear magnetic resonance (C NMR), reversed-phase high-performance liquid chromatography (RP-HPLC), and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The results showed that the CT were a mixture of catechin/epicatechin, galatechin/epicatechin, and amphicin/epigalin, and that the polymer chain lengths were 3-mers to 14-mers.

Competitive Inhibition of Lysine Acetyltransferase 2B by a Small Motif of the Adenoviral Oncoprotein E1A.

The adenovirus early region 1A (E1A) oncoprotein hijacks host cells via direct interactions with many key cellular proteins, such as KAT2B, also known as PCAF (p300/CBP associated factor). E1A binds the histone acetyltransferase (HAT) domain of KAT2B to repress its transcriptional activation. However, the molecular mechanism by which E1A inhibits the HAT activity is not known.
