Metformin Restores Mitochondrial Function and Neurogenesis in POLG Patient‐Derived Brain Organoids

open access: yesAdvanced Science, EarlyView.
Patient‐derived POLG‐mutant cortical organoids reveal neuronal subtype‐specific mitochondrial and synaptic defects, with dopaminergic neurons most affected. Metformin treatment restores neuronal identity, mitochondrial function, and excitability, increased mtDNA maintenance, and reprogrammed metabolism via TCA and redox pathways.

Cryopreserved Human Otic Neuronal Spheroids Self‐assemble for Functional Connectivity Analysis and Long‐term Ototoxicity Evaluation

open access: yesAdvanced Science, EarlyView.
This study establishes a robust and reproducible protocol for generating human otic neuronal spheroids (hONS) from cryopreserved hPSC‐derived pre‐placodal ectoderm cells. These hONS further differentiate into functional SGN‐like neurons, which extend neurite projections toward both murine hair cells and human cortical organoids, thereby forming ...

Cats with thermal burn injuries from California wildfires show echocardiographic evidence of myocardial thickening and intracardiac thrombi. [PDF]

open access: yes, 2020
Recent increases in the prevalence and severity of wildfires in some regions have resulted in an increased frequency of veterinary burn patients. Few studies exist regarding diagnostics and management of burn wounds in veterinary patients and current ...

Multidimensional en-face OCT imaging of the retina. [PDF]

open access: yes, 2009
Fast T-scanning (transverse scanning, en-face) was used to build B-scan or C-scan optical coherence tomography (OCT) images of the retina. Several unique signature patterns of en-face (coronal) are reviewed in conjunction with associated confocal images ...

Neutrophil Extracellular Trap Reprograms Cancer Metabolism to Form a Metastatic Niche Promoting Non‐Small Cell Lung Cancer Brain Metastasis

open access: yesAdvanced Science, EarlyView.
This study mainly combines spatial/single‐cell transcriptomics and metabolomics to reveal LOX+ Malig‐5 as NSCLC brain metastasis‐initiating cells, forming a niche with NET‐releasing neutrophils via the NET‐KRT10 axis. The metastatic niche is involved with metabolic reprogramming, with palmitic acid serving as a key metabolite.

Microbiological Analysis of Ophthalmic Solutions

open access: yesRADS Journal of Biological Research & Applied Science, 2015
Microbial corneal contamination is the most genuine confusion of contact lens wear. A defiled contact lens arrangement and embellishments can go about as a supply for microorganisms that could conceivably agree contact lens wear and prompt sight ...
