Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

MATHEMATICAL PROPERTIES OF THE GOLDEN RATIO – A FASCINATING NUMBER

open access: yesJournal of Industrial Design and Engineering Graphics, 2013
The Golden Ratio appears in many situations: in geometry, in lists with special numbers drawn up by mathematicians, in art history lectures, in rose petals arrangement or spiral shells of mollusks. This paper presents definitions and algebraic properties

The golden ratio prediction for the solar neutrino mixing

open access: yes, 2007
We present a simple texture that predicts the cotangent of the solar neutrino mixing angle to be equal to the golden ratio. This prediction is 1.4 standard deviations below the present best-fit value and final SNO and KamLAND data could discriminate it ...

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes

open access: yesFEBS Open Bio, EarlyView.
We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

Role of Formal Artistic Education in the Relationship between Golden Proportion and Perceived Beauty of Artistic Stimuli

open access: yesPsicológica
The golden ratio is defined as an uncanny relationship between numbers and beauty that roots in a two-millennia tradition. Two experiments evaluated the relationship between formal aesthetic education and the evaluation of beautifulness of artistic ...

A Hybrid Meta-Heuristic Feature Selection Method Using Golden Ratio and Equilibrium Optimization Algorithms for Speech Emotion Recognition

open access: yesIEEE Access, 2020
Speech is the most important media of expressing emotions for human beings. Thus, it has often been an area of interest to understand the emotion of a person out of his/her speech by using the intelligence of the computing devices.

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)
