Improving cold atmospheric pressure plasma efficacy on breast cancer cells control-ability and mortality by using vitamin C and static magnetic field [PDF]

open access: yes, 2023
Since the last decades, there have been numerous reports about the interaction of magnetic field (MF) and cold atmospheric plasma (CAP) with the biological systems, separately. In this manuscript, we have investigated the combined effect of CAP with the static magnetic field (SMF) as an effective method for cancer cells treatment.

Exogenous Melatonin Counteracts NaCl-Induced Damage by Regulating the Antioxidant System, Proline and Carbohydrates Metabolism in Tomato Seedlings

open access: yesInternational Journal of Molecular Sciences, 2019
Melatonin, a natural agent, has multiple functions in animals as well as in plants. However, its possible roles in plants under abiotic stress are not clear. Nowadays, soil salinity is a major threat to global agriculture because a high soil salt content

Calcium and Calmodulin Are Involved in Nitric Oxide-Induced Adventitious Rooting of Cucumber under Simulated Osmotic Stress

open access: yesFrontiers in Plant Science, 2017
Osmotic stress is a major form of abiotic stress that adversely affects growth and development of plants and subsequently reduces yield and quality of crops. In this study, the effect of nitric oxide (NO) and calcium (Ca2+) on the process of adventitious

How Scarification, GA3 and Graphene Oxide Influence the In Vitro Establishment and Development of Strelitzia

open access: yesPlants, 2023
The propagation of strelitzia plants can be carried out in vitro as an alternative to combine the aseptic conditions of the culture medium with the use of strategies to promote germination and controlled abiotic conditions.

Role of Gamma-Aminobutyric Acid in Plant Defense Response

open access: yesMetabolites, 2023
Gamma-aminobutyric acid (GABA) is a four-carbon non-protein amino acid that acts as a defense substance and a signaling molecule in various physiological processes, and which helps plants respond to biotic and abiotic stresses. This review focuses on the

Seed Priming with Melatonin Improves the Seed Germination of Waxy Maize under Chilling Stress via Promoting the Antioxidant System and Starch Metabolism

open access: yesScientific Reports, 2019
Chilling stress is one of the major abiotic stresses affecting waxy maize plant growth. Melatonin (MT) is able to improve tolerance to abiotic stress in plants.

The Significance of Reactive Oxygen Species and Antioxidant Defense System in Plants: A Concise Overview

open access: yesFrontiers in Plant Science, 2021
In plants, there is a complex and multilevel network of the antioxidative system (AOS) operating to counteract harmful reactive species (RS), the foremost important of which are reactive oxygen species (ROS), and maintain homeostasis within the cell ...

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...
