Excessive cholesterol accelerates intervertebral disc degeneration by promoting the polarization of M1 macrophages

open access: yesLipids in Health and Disease
Intervertebral disc degeneration (IVDD) is the primary cause of low back pain (LBP). Dyslipidaemia can induce a chronic inflammatory state in the body, promote the polarization of macrophages, and may affect the homeostasis of the intervertebral disc (IVD).

Demo 06-01 Angular Acceleration Machine

open access: yes, 2001
This device illustrates the application of the rotational analog of Newton's second law, t = I a. Two weights can be positioned symmetrically along an arm that rotates in a vertical plane around its center, varying the moment of inertia of the rotating

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

open access: yesAging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Antioxidative Phytochemicals Accelerate Epidermal Terminal Differentiation via the AHR-OVOL1 Pathway: Implications for Atopic Dermatitis

open access: yesActa Dermato-Venereologica, 2018
Aryl hydrocarbon receptor (AHR) is a chemical sensor that is expressed abundantly in epidermal keratinocytes. Oxidative AHR ligands induce the production of reactive oxygen species.

Excessive Internet use: Implications for sexual behaviour [PDF]

open access: yes, 2000
The Internet appears to have become an ever-increasing part in many areas of people’s day-to- day lives. One area that deserves further examination surrounds sexual behavior and excessive Internet usage.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Surfatron and stochastic acceleration of electrons in astrophysical plasmas [PDF]

open access: yes, 2005
Electron acceleration by large amplitude electrostatic waves in astrophysical plasmas is studied using particle-in-cell (PIC) simulations. The waves are excited initially at the electron plasma frequency $\omega_{\rm pe}$ by a Buneman instability driven ...

White Matter Hyperintensity Burden and Short‐Interval Change Associated With Sleep Apnoea in the UK Biobank

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined.
