Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Comparison of two types of extension tubes for people with Parkinson’s disease in advanced treatment with levodopa–entacapone–carbidopa intestinal gel infusions: a prospective, crossover quality study

open access: yesBMJ Open Quality
Background Within Parkinson’s disease (PD) management, a pivotal juncture often arises when individuals with PD (PwP) necessitate advanced therapies to stabilise symptom fluctuations and reduce off-periods, which are intrinsic to living with PD. One such

A Novel Dual-Frequency Deep Brain Stimulation Paradigm for Parkinson’s Disease

open access: yesNeurology and Therapy, 2019
Introduction Deep brain stimulation (DBS) of the subthalamic nucleus (STN) using high-frequency (130–185 Hz) stimulation (HFS) is more effective for appendicular than for axial symptoms.

Systematic Social Observation of Public Spaces: A New Look at Disorder in Urban Neighborhoods1

open access: yesAmerican Journal of Sociology, 1999
This article assesses the sources and consequences of public disorder. Based on the videotaping and systematic rating of more than 23,000 street segments in Chicago, highly reliable scales of social and physical disorder for 196 neighborhoods are ...

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Pilot study of circulating cell-free mitochondrial DNA in relation to brain structure in youth bipolar disorder

open access: yesInternational Journal of Bipolar Disorders
Background Mitochondrial dysfunction is implicated in the neuropathology of bipolar disorder (BD). Higher circulating cell-free mitochondrial DNA (ccf-mtDNA), generally reflecting poorer mitochondrial health, has been associated with greater symptoms ...
