A Bacterial Metabolite Causes Changes in Neurodegeneration and Aging Via Bioactivation and Hormesis in Caenorhabditis Elegans
Millions of individuals worldwide are affected by neurodegenerative disorders, that result in the progressive deterioration of cells within the nervous system and particular regions of the brain. A leading risk factor to developing neurodegenerative disorders is aging, however, aging cannot be …

Studying the Effect of Low Doses of Ionization Radiation on Senescence in Human Lung Fibroblasts.
… intriguing findings have proposed the “Radiation Hormesis” hypothesis. Herein, I studied the senescence effects of LDR exposure to normal human HFL1 cells and examined transcriptional changes. I found that HFL1 cells exposed to 10 mGy of gamma radiation had delayed senescence measured at 12 weeks …

Chronic toxicity of phthalates, biphenol and a Canadian bottled water stored under different light regimes using the Cnidarian Hydra Viridissima©
… low doses and DBP and DEHP both showed signs of hormesis.

An evaluation of theories concerning the health effects of low-dose radiation exposures
… linear-no-threshold (LNT), threshold, and hormesis. The available evidence for and against these theories, which falls into the categories of either epidemiological studies, in vitro cell experiments, or in vivo animal experiments, includes studies which support each of the four theories. …

A CHARACTERIZATION OF SELECTION FOR EVOLVED RESISTANCE TO PROTOPORPHYRINOGEN OXIDASE (PPO)-INHIBITING HERBICIDES IN AMARANTHUS TUBERCULATUS
… were conducted to improve understanding of hormesis and soil-residual PPO-inhibiting herbicides. Experiments indicated that PPO-inhibiting herbicides may exert a limited hormetic effect on waterhemp germination below doses that cause a phytotoxic effect of the emerging seedling, indicating …

Impact of an Acute Bout of Low- and High-Frequency Neuromuscular Electrical Stimulation on Voluntary Muscle Fatigue and Antioxidant Response
… reduction in antioxidant defense consistent with hormesis. Overall, NMES elicits consistent fatigue and cardiovascular responses, with stimulation frequency having minimal impact on these acute outcomes. Clinically, these findings indicate that NMES can reliably produce meaningful neuromuscular …

Phytoremediation with hemp (Cannabis sativa L.): a look at hemp's potential for environmental cleanup and economic recovery
… levels up to 2100 mg V kg-1 DW. Interestingly, hormesis (stimulated growth) was observed in hemp supplied with V: biomass increased at all tested levels. From this study, it was concluded that hemp may have potential for phytoremediation in cleaning contaminated sites with the four elements …

Turning up the heat: can post-exercise hot water immersion be used to manipulate acute physiological responses & chronic adaptation following resistance training?
… recently been articulated within the concept of hormesis, with post-exercise strategies aiming to optimise the exercise stimulus. The complex interplay between acute physiological responses and recovery/adaptation requires further investigation as recovery remains one of the least understood …

Chronic contact exposure to realistic soil concentrations of a neonicotinoid insecticide represents a potentially important and unexplored route of exposure for ground nesting bees
In the face of widespread declines, the non-target effects of pesticides on ecologically and economically important bees are an area of growing concern. One class of pesticides that has gained considerable attention over the past two decades is the neurotoxic neonicotinoid insecticides. …

Carcinoma tiroideo, ambiente vulcanico e metalli pesanti
Osservazioni epidemiologiche indicano un aumento dell’incidenza del carcinoma tiroideo nelle aree vulcaniche, dove bassi livelli di inquinamento da metalli pesanti contaminano i residenti. Per la maggior parte di questi metalli non sono disponibili dati relativi al loro effetto sulla ghiandola …

Hormetic dietary phytochemicals from Western Canadian plants: Identification, characterization and mechanistic insights
Activation of mammalian stress responsive pathways by plant secondary metabolites may contribute to the protection against certain chronic diseases afforded by fruit and vegetable consumption. This work focuses on the identification of plant compounds that activate the stress-responsive enzyme …
