Ruthenium-Based Heterocyclic Carbene-Coordinated Olefin Metathesis Catalysts [PDF]

open access: yes, 2010
The fascinating story of olefin (or alkene) metathesis (eq 1) began almost five decades ago, when Anderson and Merckling reported the first carbon-carbon double-bond rearrangement reaction in the titanium-catalyzed polymerization of norbornene.

Pharmacological prevention of delayed hypersensitivity reactions caused by iodinated contrast media

open access: yesWorld Allergy Organization Journal, 2021
Background: Delayed hypersensitivity reactions (DHRs) to radiocontrast media (RCM) occur in approximately 0.5–23.0% of patients and are thought to be caused by T cell-mediated mechanisms. However, an optimal pharmacological preventive strategy is not yet

Climate Change Threatens Micronutrient Density of European Winter Wheat

open access: yesAdvanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Anaphylaxis to iodinated contrast media: clinical characteristics related with development of anaphylactic shock. [PDF]

open access: yesPLoS ONE, 2014
Anaphylaxis is the most severe form of radiocontrast media (RCM) induced hypersensitivity and can be life-threatening if profound hypotension is combined. With increased use of iodine based RCM, related hypersensitivity is rapidly growing.

KCNJ2 is Required for NLRP3 Inflammasome Activation That Drives Allergic Airway Inflammation and Remodeling

open access: yesAdvanced Science, EarlyView.
This study aims to evaluate the impact of the potassium channel KCNJ2 on asthma development. KCNJ2 promotes NLRP3 inflammasome activation through both Ca2+ influx and K+ efflux in airway epithelial cells, which drives allergic airway inflammation and remodeling, suggesting a promising therapeutic target for asthma.

Iterative solutions to the steady state density matrix for optomechanical systems [PDF]

open access: yes, 2014
We present a sparse matrix permutation from graph theory that gives stable incomplete Lower-Upper (LU) preconditioners necessary for iterative solutions to the steady state density matrix for quantum optomechanical systems.

All You Can Eat Yeast: Substituting Hexose Transporters With AtSWEET7 Alleviates Glucose Repression, Enabling Simultaneous Utilization of Sugars in Renewable Feedstocks

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Yeast sugar transporters have highly evolved for preferential glucose transport, a significant roadblock for utilizing non‐glucose sugars in renewable feedstocks such as lignocellulosic biomass. To enable simultaneous transport of multiple sugars, native hexose transporters were replaced by SWEET7p from Arabidopsis thaliana in engineered ...
