Advances in structural modification of fucoidans, ulvans, and carrageenans to improve their biological functions for potential therapeutic application.

Marine sulfated polysaccharides constitute a class of bioactive polymers commonly found in cell walls of macroalgae. Among these macromolecular substances, fucoidans, ulvans, and carrageenans have attracted considerable attention providing interesting therapeutic properties affected by a combination of various structural factors, such as sulfation pattern, molecular weight, monosaccharide composition, and glycosidic linkages. Remarkably, chemical modification, enzymatic hydrolysis and crosslinking are promising approaches for developing the application of these polysaccharides through enhancement and/or addition of new biological properties.

Antioxidants from leaves: LC-MS/MS chemical profiling, in vitro antiglycation, α-glucosidase and α-amylase inhibitory activities.

The present study evaluated a range of biological activities of leaves, often considered as by-products, in relation to hyperglycemia. The antiglycation potential of this plant has not been previously reported. In this research, the methanolic leaf extract of was assessed for its antioxidant, enzyme inhibitory and antiglycation activities.

Effects of mycorrhizal symbiosis and seaweed extract on growth, carbon/nitrogen metabolism, and antioxidant response in cadmium-stressed sorghum plant.

In our study on the effect of cadmium (Cd) toxicity (200 µM) on the growth of (L.) Moench plants, cultivated with arbuscular mycorrhizal fungi (AMF) () and/or under seaweed treatment (3% extract) (), we found that AMF increased the tolerance of sorghum to cadmium stress, either alone or in combination with the seaweed treatment. Morphological parameters were higher in these two culture conditions, with increased chlorophyll content.

Sage leaf rock rose water extract: a bio-solution for enhancing the growth and salt stress resistance of sorghum plants.

, a versatile cereal grain, holds significant agronomic importance globally and plays a crucial role in addressing food insecurity. However, salinity, a major abiotic stress, poses a threat to food production by reducing soil fertility and hindering plant growth and yield. In this study, we investigated the potential of water extract (CSE) in mitigating salt stress in sorghum plants.

water extract: a biochemical composition that enhanced the plants growth.

The burgeoning world population is exerting immense pressure on the agricultural sector to increase yield production, which has resulted in the widespread use of chemical products by farmers. However, these chemicals can have detrimental effects on both human health and the environment. To mitigate these risks, it is crucial to identify natural solutions that are less harmful to both humans and the environment.

Saltbuch extract: a bio-solutionfor cadmium stress sorghum plants in germination and maturation.

Cadmium (Cd) is one of the dangerous factors that have negative impacts on plants and human health. Recently, many researchers have been looking for biostimulants to use as bioprotectants that can help or ameliorate plants' tolerance against abiotic stress, including Cd. To test the dangerousness of Cd accumulated in the soil, 200 µM of the latter was applied to sorghum seeds at germination and maturation stages.

Phytochemical profile and antioxidant capacity, α-amylase and α-glucosidase inhibitory activities of Oxalis pes-caprae extracts in alloxan-induced diabetic mice.

Diabetes and its complications are closely correlated with chronic hyperglycemia, causing severe oxidative stress and leading to glycation reaction with formation of advanced glycation end products. However, medicinal plants are still a source of inspiration for the discovery of new treatments of several diseases, including diabetes. The present study was aimed to evaluate the antioxidant and antidiabetic properties of Oxalis pes-caprae flowers extract in alloxan-induced diabetic mice.

Thymoquinone Alleviates Cadmium Induced Stress in Germinated Seeds by Reducing Oxidative Stress and Increasing Antioxidative Activities.

This study investigated the effect of thymoquinone on seeds germination and young seedlings of lentils under cadmium (Cd) stress (300 µM). Three different concentrations (10 µM, 1 µM, and 0.1 µM) of thymoquinone were applied.

Synergistic antioxidant effects of natural compounds on HO-induced cytotoxicity of human monocytes.

Natural compounds are endowed with a broad spectrum of biological activities, including protection against Toxins. Most of them are known for their antioxidant and radical scavenging activities. However, the synergistic combination of these natural molecules is not well studied.

Insight into extract for potential biostimulant effects in modulating cadmium-induced stress in sorghum plant.

The main aim of the current study was to investigate the role of leaves extract (CSE) in alleviating the toxic effect of cadmium (Cd) in sorghum () plants. The plants exposed to Cd (200 µM) exhibited limited growth, reduced biomass, and chlorophyll content compared to unstressed ones. Nevertheless, supplementation of CSE restored the negative effect of Cd and increased biomass and pigment content.

Extract as a Biostimulant to Enhance Tolerance to Salinity in Tomato Plants.

Salinity is a severe abiotic problem that has harmful impacts on agriculture. Recently, biostimulants were defined as bioprotectant materials that promote plant growth and improve productivity under various stress conditions. In this study, we investigated the effect of Crataegus oxyacantha extract as a biostimulant on tomato plants (Solanum lycopersicum) grown under salt stress.
