Dendrobium moniliforme Exerts Inhibitory Effects on Both Receptor Activator of Nuclear Factor Kappa-B Ligand-Mediated Osteoclast Differentiation in Vitro and Lipopolysaccharide-Induced Bone Erosion in Vivo

open access: yesMolecules, 2016
Dendrobium moniliforme (DM) is a well-known plant-derived extract that is widely used in Oriental medicine. DM and its chemical constituents have been reported to have a variety of pharmacological effects, including anti-oxidative, anti-inflammatory, and

Multi-targeted quinazolinone-Schiff's bases as potent bio-therapeutics

open access: yesResults in Chemistry, 2020
Two series of quinazolinone derived Schiff's bases were synthesized and characterized by analytical and spectroscopic techniques. All the compounds were screened for their in vitro biological studies.

Fluorescence lifetime spectroscopy of tissue autofluorescence in normal and diseased colon measured ex vivo using a fiber-optic probe

open access: yes, 2013
We present an ex vivo study of temporally and spectrally resolved autofluorescence in a total of 47 endoscopic excision biopsy/resection specimens from colon, using pulsed excitation laser sources operating at wavelengths of 375 nm and 435 nm.

Search for New Particles Decaying to Dijets at CDF [PDF]

open access: yes, 1997
We have used 106 pb^-1 of data collected with the Collider Detector at Fermilab to search for new particles decaying to dijets. We exclude at the 95% confidence level models containing the following new particles: axigluons and flavor universal colorons ...

Sensorized Engineered Tissues with Built‐in Thermoregulation and Nutrient Supply

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a granular hydrogel‐based tissue engineering platform that includes a closed‐loop temperature control to maintain 37°C and sustainably releases nutrients, thereby enabling cells to retain a high viability even if stored at room temperature for up to 24 h.

Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

open access: yesAdvanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.

On the Gierer-Meinhardt System with Saturation [PDF]

open access: yes, 2004
We consider the following shadow Gierer-Meinhardt system with saturation: \left\{\begin{array}{l} A_t=\epsilon^2 \Delta A -A + \frac{A^2}{ \xi (1+k A^2)} \ \ \mbox{in} \ \Omega \times (0, \infty),\\ \tau \xi_t= -\xi +\frac{1}{|\Omega|} \int_\Om A^2 ...

Mechanochromism of Glassy Polymers Enabled by a Loop‐Forming Supramolecular Mechanophore

open access: yesAdvanced Functional Materials, EarlyView.
The supramolecular mechanophore LOOP is covalently introduced into glassy polymers, capable of reporting force‐induced pre‐failure damage and local fracture events in polymer glasses. Under different mechanical deformation modes, including grinding, tensile stretching, and scratching, LOOP probes irreversible events in polymer glasses through a ...

"A First Evaluation of the Institutional Framework for European Monetary Policy" [PDF]

open access: yes, 2000
I will confine myself to institutional aspects concerning the design of the ESCB, to questions with regard to an appropriate political counterweight to the ECB, and to the relationship between the ESCB and the political decision-making body ECOFIN (or ...

Diagonal Based Feature Extraction for Handwritten Alphabets Recognition System using Neural Network

open access: yes, 2011
An off-line handwritten alphabetical character recognition system using multilayer feed forward neural network is described in the paper. A new method, called, diagonal based feature extraction is introduced for extracting the features of the handwritten
