Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Metrics on RNA Secondary Structures

Journal of Computational Biology, 2000
Many different programs have been developed for the prediction of the secondary structure of an RNA sequence. Some of these programs generate an ensemble of structures, all of which have free energy close to that of the optimal structure, making it important to be able to quantify how similar these different structures are.

Are secondary structures secondary?

International Journal of Peptide and Protein Research, 1984
Crystallographically observed secondary structures in globular proteins are divided into two categories based on calculated potential values for these structures. Type I secondary structures are those which have maximum potential in observed structural state.

Secondary structure of halorhodopsin

Biochemistry, 1986
Ultraviolet circular dichroism (CD) spectroscopy in the interval from 190 to 240 nm has been used to estimate the secondary structural content of halorhodopsin (hR), a light-driven chloride pump isolated from the membranes of Halobacterium halobium. Least-squares curve fitting of the CD spectrum for hR solubilized with octyl glucoside yields an alpha ...

Structural Analysis of Secondary Babbits

Metallurgist, 2021
Repairing equipment with sleeve bearings requires a large amount of expensive babbit. Babbits have low hardness, low melting point, and increased ductility. They are run-in well in friction units, have high antifriction properties, and resist shock loads well.
