Effects of Psychological Stress on Spontaneous Itch and Mechanical Alloknesis of Atopic Dermatitis

Acta Dermato-Venereologica
Atopic dermatitis (AD), a chronic inflammatory skin disease, manifests as an intractable itch. Psychological stress has been suggested to play a role in the onset and worsening of AD symptoms.

Periodic mechanical stress activates MEK1/2-ERK1/2 mitogenic signals in rat chondrocytes through Src and PLCγ1

Brazilian Journal of Medical and Biological Research, 2011
The mitogenic effects of periodic mechanical stress on chondrocytes have been studied extensively but the mechanisms whereby chondrocytes sense and respond to periodic mechanical stress remain a matter of debate.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Epigenetic mechanisms of stress and depression

Psychiatria Polska, 2019
Etiopatogeneza zaburzeń nastroju, nie jest w pełni poznana. Wśród możliwych przyczyn tych zaburzeń bierze się pod uwagę czynniki genetyczne. Dotychczas nie udało się zidentyfikować mutacji pojedynczego genu odpowiadającego za objawy kliniczne, dlatego w etiologii tych chorób sugeruje się udział mechanizmów epigenetycznych, które polegają na wywołaniu ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Plants Stress: Salt Stress and Mechanisms of Stress Tolerance

Current Agriculture Research Journal, 2023
A diverse combination of biotic and abiotic pressures makes up the environment that plants naturally inhabit. These pressures cause similarly complicated responses in plants. The purpose of the review is to critically evaluate the effects of various stress stimuli on higher plants with an emphasis on the typical and distinctive dose-dependent responses

Modeling temperature and residual stress fields in selective laser melting [PDF]

, 2018
The paper investigates the temperature and residual stress fields in the selective laser melting (SLM) process. A three-dimensional thermo-mechanical coupling model is developed to simulate a multi-track multi-layer SLM process using the finite element ...

Periodic Mechanical Stress Stimulates GIT1-Dependent Mitogenic Signals in Rat Chondrocytes Through ERK1/2 Activity

Cellular Physiology and Biochemistry, 2018
Background/Aims: The mitogenic effects of periodic mechanical stress on chondrocytes have been studied extensively, but the mechanisms whereby chondrocytes sense and respond to mechanical stimuli remain to be determined.

Mechanical stress accompanied with nuclear rotation is involved in the dormant state of mouse oocytes

Science Advances, 2019
Compression keeps oocytes dormant. The most immature oocytes remain dormant in primordial follicles in the ovary, ensuring the longevity of female reproductive life.
