The Efficiency of Water Vapor on Top‐of‐Atmosphere Radiation

open access: yesGeophysical Research Letters
Earth's climate sensitivity is greatly affected by the compensation between temperature feedback and water vapor (WV) feedback. Using abrupt 4xCO2 experiments, we show that the global‐mean WV feedback is nearly a linear function of the temperature ...

Radiation Esophagitis

open access: yesArchives of Pathology & Laboratory Medicine, 2015
The esophagus is frequently exposed to radiation during treatment of advanced stages of common cancers such as lung, breast, and esophagus. However, symptomatic radiation esophagitis requiring endoscopic and histologic evaluation occurs quite rarely, affecting less than 1% of patients receiving radiation treatment.

ATG4B is required for mTORC1‐mediated anabolic activity and is associated with clinical outcomes in non‐small cell lung cancer

open access: yesFEBS Open Bio, EarlyView.
The relationship between anabolic and catabolic processes governing lung cancer cell growth is nuanced. We show that ATG4B, an autophagy regulator, is elevated in lung cancer and that high ATG4B is associated with worse patient outcomes. Targeting ATG4B in cells reduces growth, protein synthesis, and mTORC1 activity, demonstrating a new relationship ...

Protective Effects of Quercetin on Intestinal Damage Caused by Ionizing Radiation

open access: yesHaseki Tıp Bülteni, 2018
Aim: The aim of this study was to evaluate the protective use of quercetin in a rat model of radiation-induced enteritis and colitis. Methods: Twenty four adult rats were randomly divided into four groups. Group SHAM was given only physiological saline,

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Anticancer sensitivities and biological characteristics of HCT116 cells resistant to the selective poly(ADP‐ribose) glycohydrolase inhibitor

open access: yesFEBS Open Bio, EarlyView.
We analyzed alterations of PAR metabolism‐related proteins in PARG inhibitor‐resistant HCT116RPDD cells. Although PARG levels remained unchanged, HCT116RPDD cells exhibited reduced PARP1 and ARH3 expression and elevated PAR levels. Interestingly, HCT116RPDD cells exhibited slightly elevated intracellular NAD+/NADH and ATP levels. Our findings suggest a

Case of a 35‐Year‐Old Man With Pain With Sneezing and Leg Weakness Causing Collapse

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This case details a 35‐year‐old man with no past medical history who presents with acute paraparesis and urinary retention in the setting of progressive paresthesias and weakness of his lower and upper extremities over several months. He was found to have longitudinally extensive transverse myelitis involving the cervical to mid‐thoracic cord ...

Radiated relics [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
“The history of the atomic age is intertwined with that of photography. Uranium’s radioactivity was discovered through a photograph,” says Elin O’Hara Slavick. She is the first American to photograph objects from the Hiroshima Peace Memorial Museum that were exposed to an atomic blast.

Lesion Location and Functional Connections Reveal Cognitive Impairment Networks in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.
