Published: September 2015

Though dietary azuki bean (Vigna angularis) seed containing antioxidant proanthocyanidins was known to have multibiological activities including antioxidant, hypotensive, anti-inflammatory, and immunomodulatory activities, the antiangiogenic activity of ethanol extract of Vigna angularis (EVA) was never reported so far. In the present study, the antiangiogenic mechanism of EVA was examined in human umbilical vein endothelial cells (HUVECs). EVA showed weak cytotoxicity in HUVECs, while it significantly suppressed the VEGF induced proliferation of HUVECs. Consistently, wound healing assay revealed that EVA inhibited the VEGF induced migration of HUVECs. Also, EVA abrogated the VEGF induced tube formation of HUVECs in a concentration dependent fashion. Furthermore, Matrigel plug assay showed that EVA significantly reduced the hemoglobin level of Matrigel plug in mice compared to untreated control. Of note, EVA effectively attenuated the phosphorylation of VEGFR2, Erk, and Akt in VEGF-treated HUVECs. Overall, our findings suggest that EVA inhibits angiogenesis in VEGF-treated HUVECs via inhibition of phosphorylation of VEGFR2, ERK, and Akt.

A varietal origin of eugenol was previously demonstrated in Baco blanc, a major grapevine variety used to produce Armagnac wine spirits. Eugenol was found in high amount, both as the free and as unidentified glycosylated forms. To reveal their identity, a specific method was developed and applied to berry skin extracts.

Background/objectives: Polyphenols represent a new strategy of dietary intervention for heat stress regulation.

Methods: The metabolic and genetic effects of three heat stress-regulated mung bean polyphenols on mouse small intestinal epithelial Mode-k cells were investigated by metabolomics-transcriptomics correlation analysis at different heat stress levels.

Results: Lipid metabolism, energy metabolism, and nervous system pathways were the key metabolic regulatory pathways.

The double-lumen endotracheal tube (DLT) was introduced by Carlens in 1949 and became widely used for single-lung ventilation. DLTs have since become standard for most pulmonary resections. Although the use of DLTs is routine and safe in experienced hands, it is not without risk.

Adult Plastic Bronchitis: A Rare Cause for Chronic Productive Cough.

Ann Thorac Surg Short Rep

September 2024

Division of Thoracic and Cardiovascular Surgery, Lahey Hospital and Medical Center, Burlington, Massachusetts.

Plastic bronchitis is a rare disease with serious morbidity. We report a case of a 48-year-old male smoker with a past medical history of diabetes, emphysema, recurrent respiratory infections, a worsening productive cough, and increased oxygen requirement over the past 3 months. Often described in the pediatric population, it is important to maintain plastic bronchitis in the differential when considering unresolving pulmonary conditions with chronic sputum production.
