PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

A New Approach and Analysis of Modeling the Human Body in RFID-Enabled Body-Centric Wireless Systems

open access: yesInternational Journal of Antennas and Propagation, 2014
Body-centric wireless systems demand wearable sensor and tag antennas that have robust impedance matching and provide enough gain for a reliable wireless communication link.

Measurement of local evaporative resistance of a typical clothing ensemble using a sweating thermal manikin

open access: yesJapan Architectural Review, 2020
To accurately simulate human physiology and thermal comfort, certain human physiological and comfort models categorize the human body into multiple parts. Most of these body parts are normally clothed, which must be quantified in the simulation. However,

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Comparison of strength profile representations using musculoskeletal models and their applications in robotics

open access: yesFrontiers in Robotics and AI
Musculoskeletal models provide an approach towards simulating the ability of the human body in a variety of human-robot applications. A promising use for musculoskeletal models is to model the physical capabilities of the human body, for example ...

Evaluation of Resonance Properties of the Human Body Models Situated in the RF Field

open access: yesAdvances in Electrical and Electronic Engineering, 2012
The radio-frequency (RF) electromagnetic field absorption in the human body model is investigated in this article. Absorption of prolate model of the biological body exhibits resonance properties in the case of so called E polarization.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Safety of children in cars: A review of biomechanical aspects and human body models

open access: yesIATSS Research, 2015
The protection of children in motor vehicle crashes has improved since the introduction of child restraint systems. However, motor vehicle crashes remain one of the top leading causes of death for children.
