Reduction in lumen area is associated with the δ18 O exchange between sugars and source water during cellulose synthesis.

New Phytologist, 2020
High temporal resolution measurements of wood anatomy and the isotopic composition in tree-rings have the potential to enhance our interpretation of climate variability, but the sources of variation within the growing season are still not well understood.

Wood day capacitance is related to water content, wood density, and anatomy across 30 temperate tree species.

Plant, Cell and Environment, 2020
Water released from wood during transpiration (capacitance) can meaningfully affect daily water use and drought response. To provide context for better understanding of capacitance mechanisms, we investigated links between capacitance and wood anatomy ...

Tree-ring anatomy and carbon isotope ratio show both direct and legacy effects of climate on bimodal xylem formation in Pinus pinea

Tree Physiology, 2018
Understanding how climate affects xylem formation is critical for predicting the impact of future conditions on tree growth and functioning in the Mediterranean region, which is expected to face warmer and drier conditions.

EUS-Guided Gallbladder Drainage Using a Lumen-Apposing Metal Stent for Acute Cholecystitis: Results of a Nationwide Study with Long-Term Follow-Up

Diagnostics
Background: Although endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using lumen-apposing metal stents (LAMS) has become one of the treatments of choice for acute cholecystitis (AC) in fragile patients, scant data are available on real-life ...

Lumen-Apposing Metal Stent Used to Treat Malignant Esophageal Stricture

ACG Case Reports Journal, 2020
Malignant esophageal strictures often require stent placement to alleviate dysphagia and improve quality of life. We present a novel application of a lumen-apposing metal stent to bypass a malignant esophageal stricture in the setting of altered gastric ...

Molecular Anatomy of Plant Photoprotective Switches: The Sensitivity of PsbS to the Environment, Residue by Residue

Journal of Physical Chemistry Letters, 2019
Under strong sunlight, plants avoid photooxidation by quenching the excess absorbed energy. Quenching is triggered by PsbS, a membrane protein that is activated and deactivated by the light-dependent pH changes in the thylakoid lumen.

Aortic Arch Anatomy Pattern in Patients Treated Using Double Homemade Fenestrated Stent-Grafts for Total Endovascular Aortic Arch Repair

Journal of Endovascular Therapy, 2020
Purpose: To analyze the structural variation of the aortic arch and the supra-aortic arteries and establish an average spatial configuration that would be a pattern for a “universal double fenestration” design for physician-modified endovascular grafts ...
