The Hückel total π-electron energy puzzle [PDF]

open access: yesJournal of the Serbian Chemical Society, 2006
In spite of being based on drastic simplifications, the Hückel molecular orbital (HMO) quantum-mechanical model provides a reasonably good description of the properties of π-electrons in conjugated molecules.

Decorin expression is important for age-related changes in tendon structure and mechanical properties [PDF]

open access: yesMatrix Biology, 2013
The aging population is at an increased risk of tendon injury and tendinopathy. Elucidating the molecular basis of tendon aging is crucial to understanding the age-related changes in structure and function in this vulnerable tissue. In this study, the structural and functional features of tendon aging are investigated. In addition, the roles of decorin

The Mechanical Properties of Drosophila Jump Muscle Expressing Wild-type and an Embryonic Myosin Isoform [PDF]

open access: yesBiophysical Journal, 2009
Transgenic Drosophila are highly useful for structure-function studies of muscle proteins. However, our ability to mechanically analyze transgenically expressed mutant proteins in Drosophila muscles has been limited to the skinned indirect flight muscle preparation. We have developed a new muscle preparation using the Drosophila tergal depressor of the

Biomedical response of femurs in male Wistar rat in chronic hypergravity environments

open access: yesMedicine in Novel Technology and Devices, 2022
Bone is sensitive to mechanical stimulation and plays a loading-bearing role in the human body. However, regulation of bone biomechanical properties in chronic hypergravity environments is still unclear. In this study, male Wistar rats exposed to chronic

Expression analysis for candidate genes associated with eggshell mechanical property

open access: yesJournal of Integrative Agriculture, 2016
Abstract: Damaged eggshells result in losses of eggs. The genetic mechanism of variable eggshell strength is still unclear. The current study was conducted to verify whether the eggshell calcification related genes, CALB1, SPP1, DMP4, BMP2 and SLIT2, were associated with eggshell mechanical property.
