Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Evidence and Impacts of Nanoplastic Accumulation on Crop Grains

open access: yesAdvanced Science, 2022
Nanoplastics are emerging pollutants of global concern. Agricultural soil is becoming a primary sink for nanoplastics generated from plastic debris. The uptake and accumulation of nanoplastics by crops contaminate the food chain and pose unexpected risks

Behavioural compensation by drivers of a simulator when using a vision enhancement system [PDF]

open access: yes, 2000
Technological progress is suggesting dramatic changes to the tasks of the driver, with the general aim of making driving environment safer. Before any of these technologies are implemented, empirical research is required to establish if these devices do,

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Hysteresis and the Limits of Homeostasis: from Daisyworld to Phototaxis [PDF]

open access: yes, 2005
All biological organisms must be able to regulate certain essential internal variables, e.g. core body temperature in mammals, in order to survive. Almost by definition, those that cannot are dead. Changes that result in a mammal being able to tolerate a

Mechanisms altering airway smooth muscle cell Ca(2+) homeostasis in two asthma models [PDF]

open access: yes, 2008
Background: Asthma is characterized by airway remodeling, altered mucus production and airway smooth muscle cell (ASMC) contraction causing extensive airway narrowing. In particular, alterations of ASMC contractility seem to be of crucial importance. The

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

"Homeostasis" of living systems and 1/f fluctuations [PDF]

open access: yes, 2002
P(論文)Based on mathematical models fluctuation phenomena which appear in stationary states of living systems are considered. It is shown that feedback processes which realize "homeostasis" in living systems, in general, lead to a number of types of ...
