Response to Allopurinol and Febuxostat According to the Fractional Excretion of Urate in Men With Gout

open access: yesArthritis Care &Research, EarlyView.
Objective Body mass index (BMI), glomerular filtration rate (GFR), and pretreatment urate levels have been reported to influence the urate‐lowering response to allopurinol. We investigated whether the fractional excretion of uric acid (FEUA) also modulates this response and relates to oxypurinol concentrations.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Four Artificial Heart Valves [PDF]

open access: yesNew England Journal of Medicine, 2005
A 67-year-old woman reported having progressive shortness of breath over several months, three years after undergoing aortic-valve replacement for aortic insufficiency. The patient had migraine headaches for which she had received 2 mg of ergotamine tartrate daily for many years. On physical examination, her blood pressure was 170/95 mm Hg.

Relationship between fibre orientation and tensile strength of natural collagen membranes for heart valve leaflets [PDF]

open access: yes, 2011
Heart valve prostheses are used to replace native heart valves which that are damaged because of congenital diseases or due to ageing. Biological prostheses made of bovine pericardium are similar to native valves and do not require any anticoagulation ...

Contribution of Extra‐Cardiac Cells in Murine Heart Valves is Age‐Dependent

open access: yesJournal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2017
Background Heart valves are dynamic structures that open and close over 100 000 times a day to maintain unidirectional blood flow during the cardiac cycle.

Composition and Resulting Band Alignment at the TiO2/InP Heterointerface: A Fundamental Study Combining Photoemission Spectroscopy and Theory

open access: yesAdvanced Functional Materials, EarlyView.
The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.

Cytokine expression profile of native heart valves obtained from patients with infective endocarditis

open access: yesМедицинская иммунология
Infectious endocarditis is characterized by dysfunction of heart valves and contribute significantly to the cardiovascular morbidity and mortality worldwide, especially in low- and middle-income countries. Immune response is playing the important role in

Inhibition of MAPK-Erk pathway in vivo attenuates aortic valve disease processes in Emilin1-deficient mouse model [PDF]

open access: yes, 2017
Aortic valve disease (AVD) is a common condition with a progressive natural history, and presently, there are no pharmacologic treatment strategies. Elastic fiber fragmentation (EFF) is a hallmark of AVD, and increasing evidence implicates developmental ...

CO2 Reduction on Copper‐Nitrogen‐Doped Carbon Catalysts Tuned by Pulsed Potential Electrolysis: Effect of Pulse Potential

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.
