Investigating transthyretin variants H88R and I107V in amyloid priming: From destabilization to complete dissociation

The FEBS Journal, Volume 293, Issue 15, Page 4680-4703, August 2026.
Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

Reliability analysis for a k/n(F) system with repairable repair-equipment [PDF]

, 2009
In this paper, the reliability and replacement policy of a k/n(F) (i.e. k-out- of-n: F) system with repairable repair-equipment is analyzed. We assume that both the working and repair times of all components in the system and the repair-equipment follow ...

Identification of Critical Machine in Textile Industry Using Reliability‐Centred Maintenance and Failure Mode and Effects Analysis—A Case Study of Bahir Dar Textile's Share Company

The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
The study aims to mitigate these risks through the implementation of a structured RCM policy. The findings indicate that the machines in the spinning section are the most critical in terms of their failure impact. Implementing the RCM methodology demonstrates significant economic benefits by reducing risk through a targeted FMEA approach.
