Summary: This review focuses on the role of the balance between reactive oxygen species (ROS) production and antioxidative system (AOS) in enhancing effective water use by crops under water-limited dryland conditions. Manipulating this balance through genetic improvement and exogenous compounds application can provide practical solutions for improving crop productivity in water-limited dryland environments.

Summary: Soil and air pollution caused by heavy metals and limestone dust in urban environments pose a significant threat to the environment and humans. This study investigated the effects of heavy metal lead (Pb) and limestone dust toxicities on the growth and physiological traits of three urban tree species seedlings. The results showed that Bombax ceiba performed better under the same levels of pollution compared to the other two species, with the ability to efficiently demolish oxidative bursts through triggering certain enzymes. The photosynthetic rate and stomatal conductance of all three tree species were negatively influenced by different levels of lead and dust pollution.

Summary: The field of oxygen free radicals, antioxidants, and reactive oxygen species (ROS) has seen significant growth, with ROS playing important roles in living organisms. However, many studies lack mechanistic meaning. Detailed understanding of the molecular mechanisms of ROS and appropriate measurement methods for both ROS and oxidative damage are necessary for progress.

Summary: Environmental surveillance-mediated behavior in Caenorhabditis elegans integrates multiple cues and is coordinated by neurons through signaling cascades. Despite lacking eyes, C. elegans is able to perceive and react to the color blue. This study explains this color perception by showing that internally-generated reactive oxygen species (ROS), in response to light, add to exogenous sources of ROS. Multiple sub-threshold sources of ROS are integrated to coordinate behavioral responses with internal cues. Blue light affects C. elegans behavior through ROS generation by endogenous flavins, mediated by the neuronal gustatory photoreceptor like protein, LITE-1. Overall, this study demonstrates that ROS and LITE-1 play central roles in C. elegans foraging behavior through integration of multiple inputs, including light.

Summary: The results of this study demonstrate that ozone treatment reduces respiration rate, maintains fruit hardness and storage quality, and inhibits the ripening and senescence of kiwifruit. Ozone treatment activates antioxidant enzymes and the ascorbate-glutathione cycle to prevent the accumulation of reactive oxygen species. Furthermore, ozone treatment is also related to hormone signaling, playing an important role in regulating ROS in kiwifruit.

Summary: Climate change has devastating effects on plants, leading to the production of reactive oxygen species (ROS) as byproducts of oxygen consumption. While excessive ROS can disrupt cellular homeostasis, moderate levels can activate growth and stress responses in plants, though the exact mechanisms are not fully understood. Advancements in modern techniques like molecular priming and crop modeling offer potential solutions for managing ROS levels in plants under stress.

Summary: Cancer and diabetes mellitus are life-threatening diseases that share common risk factors. Conventional treatments for these diseases have limitations such as side effects, economic burdens, and patient compliance. Phytochemicals from edible plants, with their antioxidant and pro-oxidant properties, have emerged as alternative therapeutic options. These naturally occurring compounds have beneficial effects and can regulate cell proliferation, differentiation, cell cycle arrest, and apoptosis, offering preventive and therapeutic effects against cancer and diabetes. This article summarizes recent studies on the antioxidant or pro-oxidant effects and underlying mechanisms of flavonoids, alkaloids, and saponins in cancer or diabetic models.

Summary: β-glucan has shown effectiveness in immune regulation and blood pressure suppression. Seaweed laminaran, a β-1,3/1,6-glucan, can be a sustainable source of β-glucan production using CO2 and seawater as growth substrates. Laminaran has been found to scavenge reactive oxygen species (ROS) and attenuate cytotoxicity caused by drugs like indomethacin and dabigatran.

Summary: Immune cells have the potential to control tumor growth, but this effect can be negated by immunosuppression caused by increased reactive oxygen species. Studies show that the antitumor effect of immune cells is linked to their antioxidant capacity. Understanding the role of reactive oxygen species in the tumor microenvironment and their effects on different immune cells is crucial for targeting antioxidant defense in immune cells for cancer treatment.

Summary: The study investigated the phytoremediation potential of Cassia tora grown in different concentrations of chromium-rich overburden soil. Results showed that C. tora has a notable ability to accumulate chromium from contaminated soil, making it a potential phytoremediator for chromium-contaminated sites. Its high bioaccumulation activity, tolerance, and transportation index make it suitable for phytostabilization programs at chromite overburden mining sites.

Summary: Many conventional and advanced methods are used to remove heavy metals, such as cadmium, from wastewater. Recent developments in materials science and chemistry have made it possible to remove cadmium using nanomaterials, which have large specific surface areas and multiple functions. Adsorption by nanomaterials is acknowledged as a viable and cost-effective method for removing dangerous metals from contaminated water. This paper examines the benefits and drawbacks of using nanomaterials for cadmium removal, as well as their production, potential effects on human health, and future research directions.

Summary: Pinus wallichiana and Dalbergia sissoo wood are commonly used in Pakistan's construction and furniture industry. However, the directional variability of their physical properties has not been well studied. Water and moisture uptake, water contact angle, and compressional strength varied significantly along the three directions for both types of wood. Water and moisture uptake were highest in the tangential direction, while water contact angle and compressional strength were highest in the longitudinal direction for both wood types. Additionally, thermal conductivity and diffusivity were highest in the longitudinal direction, while specific heat capacity was highest in the radial direction. Further investigations are needed to better understand site-specific variations in physical properties and provide improved recommendations.
