Lipopeptides from Bacillus atrophaeus MCM61 and melatonin suppress gray mold-induced oxidative stress in cut roses (Rosa hybrida L.) and improve vase life.

Application of melatonin and lipopeptides (LPs) derived from Bacillus strains is considered an efficient strategy to control plant diseases at both pre and postharvest stages. However, the combined application of melatonin and LPs has not been studied yet. Therefore, the present study presents the synergistic effect of melatonin and LPs produced by Bacillus atrophaeus strain MCM61 against gray mold disease and its impact on quality parameters and vase life of cut roses.

Xanthones: A Class of Heterocyclic Compounds with Anticancer Potential.

Xanthones (9H xanthen-9-one) are an important class of heterocyclic compounds containing oxygen and a moiety of gamma-pirone, dense with a two-benzene ring structure, distributed widely in nature. Naturally occurring xanthones are found in micro-organisms and higher plants as secondary metabolites in fungi and lichens. Compounds of the family Caryophyllaceae, Guttiferae and Gentianaceae, are the most common natural source of xanthones.

Bovine serum albumin functionalized blue emitting Ti C MXene quantum dots as a sensitive fluorescence probe for Fe ion detection and its toxicity analysis.

In the present work, an improved class of protein functionalized fluorescent 2D Ti C MXene quantum dots (MXene QDs) was prepared using a hydrothermal method. Exfoliated 2D Ti C sheets were used as the starting precursor and transport protein bovine serum albumin (BSA) was used to functionalize the MXene QDs. BSA-functionalized MXene QDs exhibited excellent photophysical property and stability at various physiological parameters.

Comparison of the Efficiency of , , and Methanolic Extracts in Relieving Hyperglycemia and Hyperlipidemia of Streptozotocin-Induced Diabetic Rats.

Background: Diabetes mellitus (DM) is a metabolic disorder characterized by high blood glucose levels that occurs either due to insufficient insulin production or mounting resistance to its action. The purpose of this study was to investigate if methanolic extracts of seeds, , and leaves had any effect on blood sugar levels in normal and streptozotocin (STZ) diabetic rats, as well as to explore the most effective extract.

Method: Healthy male albino rats weighing 185-266 g were divided into nine groups of eight rats each: normal control, diabetic control, diabetic rats with dietary supplements of , , and methanolic extracts, and diabetics treated with insulin.
