Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Multistage converter with reduced switch voltage stress and diode current stress

open access: yesIET Power Electronics
The utilization of switched inductors, involving parallel charging and series discharging of inductors, is extensively embraced in diverse DC–DC converters for attaining high voltage gain; nevertheless, the stress on switch voltage and diode current ...

The rhizobium symbiosis in Medicago truncatula induces a priming-like response and enhances drought tolerance

open access: yesPlant Stress
Legumes can fix nitrogen (N) by symbiotic N-fixation (SNF) through association with rhizobia. However, this comes at a higher carbon cost to the host as compared to direct N fertiliser uptake. We therefore hypothesised that the energy-intensive symbiosis

Application of Pulsed eddy current technique to stress and residual stress measurement [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2014
Stress and residual stress are the main problems in the operating performance of materials. They are the principal causes of material failure and can affect life time of component. However measurement or predictions of them are typically difficult.

Some Current Insights into Oxidative Stress

open access: yesPhysiological Research, 2010
Oxidative stress is a phenomenon associated with pathogenetic mechanisms of several diseases including atherosclerosis, neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease, cancer, diabetes mellitus, inflammatory diseases, as well as psychological diseases or aging processes.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Current progress and future perspective in combat stress reactions

open access: yesDi-san junyi daxue xuebao, 2019
Soldiers in the combat field may demonstrate such non-adaptive reactions as panic disorder, narrow visual field and hearing disturbance, which potentially cause non-combat attrition and compromise the high-level cognitive functions (reasoning, judgment ...

The Invalidity of the Laplace Law for Biological Vessels and of Estimating Elastic Modulus from Total Stress vs. Strain: a New Practical Method [PDF]

open access: yes, 2013
The quantification of the stiffness of tubular biological structures is often obtained, both in vivo and in vitro, as the slope of total transmural hoop stress plotted against hoop strain. Total hoop stress is typically estimated using the "Laplace law."

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our
