Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Repaired tetralogy of Fallot: the roles of cardiovascular magnetic resonance in evaluating pathophysiology and for pulmonary valve replacement decision support

open access: yesJournal of Cardiovascular Magnetic Resonance, 2011
Surgical management of tetralogy of Fallot (TOF) results in anatomic and functional abnormalities in the majority of patients. Although right ventricular volume load due to severe pulmonary regurgitation can be tolerated for many years, there is now ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Computer Architecture with Associative Processor Replacing Last-Level Cache and SIMD Accelerator

open access: yesIEEE Transactions on Computers, 2015
This study presents a novel computer architecture where a last level cache and a SIMD accelerator are replaced by an Associative Processor. Associative Processor combines data storage and data processing and provides parallel computational capabilities and data memory at the same time.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

A New Cache Replacement Policy for Improving Last Level Cache Performance

open access: yesJournal of KIISE, 2014
캐쉬 교체 기법은 캐쉬 미스를 감소시키기 위해서 개발되었다. 마이크로프로세서와 주기억장치의 속도 차이를 해결하기 위해서는 캐쉬 교체 기법의 성능이 중요하다. 일반적인 캐쉬 교체 기법으로는 LRU 기법이 있으며 대부분의 마이크로프로세서에서 캐쉬 교체 기법으로 LRU 기법을 사용한다. 그러나, 최근의 연구에 따르면 LRU 기법과 최적 교체(OPT) 기법 간의 성능 차이는 매우 크다. LRU 기법의 성능은 많은 연구를 통해서 검증되었지만, 캐쉬 사상방식이 높아질수록 LRU 기법과 OPT 기법의 성능 차이는 증가한다. 본 논문에서는 기존의 LRU 기법을 활용하여 캐쉬 성능을 향상시키는 캐쉬 교체 기법을 제안하였다.
