Brassinosteroids-Induced Systemic Stress Tolerance was Associated with Increased Transcripts of Several Defence-Related Genes in the Phloem in Cucumis sativus. [PDF]

PLoS ONE, 2013
Brassinosteroids (BRs), a group of naturally occurring plant steroidal compounds, are essential for plant growth, development and stress tolerance. Recent studies showed that BRs could induce systemic tolerance to biotic and abiotic stresses; however ...

Cellular Tolerance Induced by Chronic Opioids in the Central Nervous System

Frontiers in Systems Neuroscience, 2022
Opioids are powerful analgesics that elicit acute antinociceptive effects through their action the mu opioid receptor (MOR). However opioids are ineffective for chronic pain management, in part because continuous activation of MORs induces adaptive changes at the receptor level and downstream signaling molecules. These adaptations include a decrease in

The Foliar Application of Rice Phyllosphere Bacteria induces Drought-Stress Tolerance in Oryza sativa (L.)

Plants, 2021
This study assessed the potential of Bacillus endophyticus PB3, Bacillus altitudinis PB46, and Bacillus megaterium PB50 to induce drought tolerance in a susceptible rice cultivar.

Long term impact of systemic bacterial infection on the cerebral vasculature and microglia [PDF]

, 2012
Background: Systemic infection leads to generation of inflammatory mediators that result in metabolic and behavioural changes. Repeated or chronic systemic inflammation leads to a state of innate immune tolerance: a protective mechanism against over ...

Effect ofBacillus velezensis JC-K3 on Endophytic Bacterial and Fungal Diversity in Wheat Under Salt Stress

Frontiers in Microbiology, 2021
Plant growth-promoting bacteria (PGPB) can effectively reduce salt damage in plants. Currently, there are many studies on the effects of PGPB on the microbial community structure of rhizosphere soil under salt stress, but fewer studies on the community ...

Bacteria in Soil: Promising Bioremediation Agents in Arid and Semi-Arid Environments for Cereal Growth Enhancement

Applied Sciences, 2022
In arid regions, starchy agricultural products such as wheat and rice provide essential carbohydrates, minerals, fibers and vitamins. However, drought, desiccation, high salinity, potentially toxic metals and hydrocarbon accumulation are among the most ...

Engineering human spinal microphysiological systems to model opioid-induced tolerance

Bioactive Materials, 2022
Abstract Opioids are commonly used for treating chronic pain. However, with continued use, they may induce tolerance and/or hyperalgesia, which limits therapeutic efficacy. The human mechanisms of opioid-induced hyperalgesia are significantly understudied, in part, because current models cannot fully recapitulate human pathology.

Involvement of kappa/dynorphin system in the development of tolerance to nicotine‐induced antinociception [PDF]

Journal of Neurochemistry, 2008
AbstractThe aim of the present study was to explore the possible role of kappa/dynorphin system in the development of tolerance to nicotine antinociception in mice. First, we observed that kappa‐opioid receptor (KOP‐r) participates in the acute spinal antinociception produced by nicotine (3 and 5 mg/kg, s.c.) since the pre‐treatment with the selective ...

Azospirillum: benefits that go far beyond biological nitrogen fixation

AMB Express, 2018
The genus Azospirillum comprises plant-growth-promoting bacteria (PGPB), which have been broadly studied. The benefits to plants by inoculation with Azospirillum have been primarily attributed to its capacity to fix atmospheric nitrogen, but also to its ...

Human placental exosomes induce maternal systemic immune tolerance by reprogramming circulating monocytes [PDF]

Journal of Nanobiotechnology, 2022
Abstract Background The maternal immune system needs to tolerate the semi-allogeneic fetus in pregnancy. The adaptation occurs locally at the maternal–fetal interface as well as systemically through the maternal circulation.
