PMID: 25598773
Neural Regen Res. 2014 Nov 15;9(22):1943-8. doi: 10.4103/1673-5374.145366.

Peripheral nerve injury is a serious problem affecting significantly patients' life. Autografts are the "gold standard" used to repair the injury gap, however, only 50% of patients fully recover from the trauma. Artificial conduits are a valid alternative to...

Fiber Bragg Grating Measuring System for Simultaneous Monitoring of Temperature and Humidity in Mechanical Ventilation.

Sensors (Basel, Switzerland)

Massaroni C, Caponero MA, D'Amato R, Lo Presti D, Schena E.
PMID: 28368339
Sensors (Basel). 2017 Apr 02;17(4). doi: 10.3390/s17040749.

During mechanical ventilation, the humidification of the dry air delivered by the mechanical ventilator is recommended. Among several solutions, heated wire humidifiers (HWHs) have gained large acceptance to be used in this field. The aim of this work is...

Synthesis, Characterization, and Biological Evaluation of Nanostructured Hydroxyapatite with Different Dimensions.

Nanomaterials (Basel, Switzerland)

Geng Z, Yuan Q, Zhuo X, Li Z, Cui Z, Zhu S, Liang Y, Liu Y, Bao H, Li X, Huo Q, Yang X.
PMID: 28336873
Nanomaterials (Basel). 2017 Feb 15;7(2). doi: 10.3390/nano7020038.

Nanosized hydroxyapatite (HA) is a promising candidate for a substitute for apatite in bone in biomedical applications. Furthermore, due to its excellent bone bioactivity, nanosized strontium-substituted HA (SrHA) has aroused intensive interest. However, the size effects of these nanoparticles...

Engineering of the embryonic and adult stem cell niches.

Iranian Red Crescent medical journal

Hosseinkhani M, Shirazi R, Rajaei F, Mahmoudi M, Mohammadi N, Abbasi M.
PMID: 23682319
Iran Red Crescent Med J. 2013 Feb;15(2):83-92. doi: 10.5812/ircmj.7541. Epub 2013 Feb 05.

CONTEXT: Stem cells have the potential to generate a renewable source of cells for regenerative medicine due to their ability to self-renew and differentiate to various functional cell types of the adult organism. The extracellular microenvironment plays a pivotal...

Microscopic study on resorption of β-tricalcium phosphate materials by osteoclasts.

Cytotechnology

Matsunaga A, Takami M, Irié T, Mishima K, Inagaki K, Kamijo R.
PMID: 25672942
Cytotechnology. 2015 Aug;67(4):727-32. doi: 10.1007/s10616-015-9854-0. Epub 2015 Feb 12.

Sintered compounds prepared with β-tricalcium phosphate (β-TCP) are commonly used as biocompatible materials for bone regenerative medicine. Although implanted β-TCP is gradually replaced with new bone after resorption by osteoclasts, exactly how osteoclasts resorb β-TCP is not well understood....

Prevention of protein adsorption by flexible and rigid chain molecules.
