Scanning transmission X‐ray microscopy study of microbial calcification
Calcium phosphates and calcium carbonates are among the most prevalent minerals involved in microbial fossilization. Characterization of both the organic and mineral components in biomineralized… Expand
Soft X-ray Microscopy and Spectroscopy at the Molecular Environmental Science Beamline at the Advanced Light Source
We present examples of the application of synchrotron-based spectroscopies and microscopies to environmentally relevant samples. The experiments were performed at the molecular environmental science… Expand
Therapeutic effectiveness over time of intratympanic dexamethasone as salvage treatment of sudden deafness.
CONCLUSION Intratympanic dexamethasone (ITD) within 1 month after initial treatment failure should be utilized as salvage treatment for refractory sudden sensorineural hearing loss (SSNHL). … Expand
Adsorption of organic matter at mineral/water interfaces: I. ATR-FTIR spectroscopic and quantum chemical study of oxalate adsorbed at boehmite/water and corundum/water interfaces
Abstract The types and structures of adsorption complexes formed by oxalate at boehmite (γ-AlOOH)/water and corundum (α-Al2O3)/water interfaces were determined using in situ attenuated total… Expand
A new perspective on in vitro assessment method for evaluating quantum dot toxicity by using microfluidics technology.
In this study, we demonstrate a new perspective on in vitro assessment method for evaluating quantum dot (QD) toxicity by using microfluidics technology. A new biomimetic approach, based on the flow… Expand
Can Intratympanic Dexamethasone Added to Systemic Steroids Improve Hearing Outcome in Patients With Sudden Deafness?
Objective: To evaluate the therapeutic efficacy of intratympanic dexamethasone (ITD) injections added to systemic steroids in patients with idiopathic sudden sensorineural hearing loss (HL).
