Type A aortic dissection during transoesophageal echocardiography: a case report.

Division of Cardiology, Department of Internal Medicine, National Taiwan University Hospital, No. 7, Jhongshan S. Rd., Jhongjheng Dist., Taipei 10002, Taiwan.
Background: The occurrence of type A aortic dissection (TAAD) during transoesophageal echocardiography (TEE) has only been reported once. We present another case of pre-procedural type B AD with retrograde TAAD or TAAD during the TEE procedure.
Case Summary: An 81-year-old man with a pre-existing infrarenal abdominal aortic aneurysm and highly tortuous aorta was referred to our ward for acute decompensated heart failure (ADHF) with New York Heart Association functional class II.
h-BN in the making: The surface chemistry of borazine on Rh(111).

Borazine is a well-established precursor molecule for the growth of hexagonal boron nitride (h-BN) via chemical vapor deposition on metal substrates. To understand the formation of the h-BN/Rh(111) moiré from borazine on a molecular level, we investigated the low-temperature adsorption and thermally induced on-surface reaction of borazine on Rh(111) in situ using synchrotron radiation-based high-resolution x-ray photoelectron spectroscopy (XPS), temperature-programmed XPS, and near-edge x-ray absorption fine structure measurements. We find that borazine adsorbs mainly as an intact molecule and have identified a flat-lying adsorption geometry.

Liaoning Research Institute of Cash Crops, Liaoyang, Liaoning, China;
American ginseng (Panax quinquefolium L.) is one of the most valuable herb crops because of its unique pharmacological effects. In 2019, American ginseng plants withered and root rot with incidences of 20-45% were observed in about 70000m2 of ginseng production field located in mountainous valley of Benxi city (41º23'32" N, 124º04'27" E), Liaoning Province in China.
