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 ...

Instructional feedback to support self-regulated writing in primary school

open access: yesFrontiers in Education, 2023
Feedback that enhances self-regulated learning when writing seems to rarely be provided in classrooms to beginner writers, although acting autonomously as a writer is crucial for the pupils’ further literacy development.

Feedback-Optimized Operations with Linear Ion Crystals

open access: yes, 2009
We report on transport operations with linear crystals of 40Ca+ ions by applying complex electric time-dependent potentials. For their control we use the information obtained from the ions' fluorescence.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The effects of self-controlled and instructor-controlled feedback on motor learning and intrinsic motivation among novice adolescent taekwondo players

open access: yesActa Gymnica, 2019
Background: Although the useful effects of self-controlled feedback on motor skills learning have been proven, a study dealing with the effects of self-controlled and instructor-controlled feedback on learning and intrinsic motivation among novice ...

Adaptation to the Edge of Chaos in the Self-Adjusting Logistic Map

open access: yes, 2000
Self-adjusting, or adaptive systems have gathered much recent interest. We present a model for self-adjusting systems which treats the control parameters of the system as slowly varying, rather than constant.

Mechanisms of interpersonal sway synchrony and stability [PDF]

open access: yes, 2014
Here we explain the neural and mechanical mechanisms responsible for synchronizing sway and improving postural control during physical contact with another standing person.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

System Science Principle of the Mechanism of Acupuncture and Moxibustion

open access: yesYixue yu zhexue
Human body is a complex yet orderly system—an archetypal self-organization entity characterized by functions such as self-regulation, self-control, and self-repair, all of which rely heavily on the operation of negative feedback mechanisms.

Effects of real-time feedback during decline walking on kinematic and kinetic gait parameters in a healthy population: study protocol for a randomized trial — up and down

open access: yesTrials, 2021
Background The control of the dynamic functional leg alignment (dFLA) and biomechanical load are important joint-related aspects regarding the development of osteoarthritis (OA).
