Two-Stage Residual-Guided Diffusion Framework for High-Fidelity Pathology Image Restoration

Jeewoo Chelsea Lim, Chi-Ho Yu, Jin Tae Kwak

The digitization of whole slide images in computational pathology frequently introduces out-of-focus blur, a prevalent artifact that can compromise diagnostic accuracy. Although recent diffusion-based restoration methods have shown notable success, they often fail to reconstruct the fine-grained cellular and textural details critical …

Neuronal mitochondrial disaggregase CLPB ameliorates Huntington's disease pathology in mice

Hyeonho Kim, Gaeun Hyun, Seunghye Kim, Chi-Ho Yu et autres

Background: Huntington's disease (HD) is a devastating neurodegenerative disorder caused by CAG repeat expansion in the HTT gene, resulting in a polyglutamine-expanded huntingtin (HTT) protein that forms toxic aggregates.Although heat-shock proteins are known to facilitate the refolding or clearance of misfolded proteins, …

Detecting Hearing Impairment Through Localizing Abnormal Speech Patterns

Longbin Jin, Chi-Ho Yu, Jung Eun Shin, Eun Yi Kim

Detecting early signs of hearing impairment may help prevent age-related cognitive decline and associated disorders. However, conventional methods like pure tone audiometry are often subjective and insufficient for early detection. In this paper, we propose a novel, subject-agnostic approach for automatically detecting …

Pro- and anti-inflammatory cytokine expression and histopathological characteristics in canine brain with traumatic brain injury

Chi-Ho Yu, Ji Young Yhee, Jong Hyuk Kim, Keum-Soon Im et autres

We analyzed the expression level and cellular localization of pro- and anti-inflammatory cytokines and histopathologically characterized canine traumatic brain injury (TBI). Canine TBI brains revealed subarachnoid and cerebral cortical hemorrhage, neutrophilic infiltration, neuronal necrosis, astrocytosis, and vasogenic edema. Immunohistochemical evaluations suggested that …
