White mold, caused by the necrotrophic fungus , is a challenging disease to common bean cultivation worldwide. In the current study, two non-proteinogenic amino acids (NPAAs), -aminobutyric acid (GABA) and -alanine, were suggested as innovative environmentally acceptable alternatives for more sustainable management of white mold disease. , GABA and -alanine individually demonstrated potent dose-dependent fungistatic activity and effectively impeded the radial growth and development of mycelium.

This is the first investigation, conducted in a completely randomized design (CRD), to determine the effects of different salinity levels (75 and 150 mM) and germination periods (3, 4, and 5 days) on momilactone and phenolic accumulations in germinated brown rice (GBR) var. Koshihikari. Particularly, the identification of bioactive compounds was confirmed using electrospray ionization-mass spectrometry (ESI-MS) and nuclear magnetic resonance (NMR) spectroscopy (H and C).

Article Synopsis
  • Salinity stress significantly impacts rice production globally, prompting this study to assess fulvic acid (FA) at different concentrations to enhance the salt tolerance of three rice varieties.
  • Treatment with 0.25 mL/L of FA (T3) proved most effective, boosting growth performance and phenolic accumulation in Koshihikari, Nipponbare, and Akitakomachi under high salinity levels.
  • Specifically, concentrations of salicylic acid and momilactones, which help combat salt stress, increased notably in treated plants, indicating that FA can improve rice's ability to withstand salinity stress, warranting further investigation in agricultural settings.

The important vegetable crop, tomato, is challenged with numerous abiotic and biotic stressors, particularly the newly emerged fungicide-resistant strains of phytopathogenic fungi such as , the causal agent of early blight disease. The current study investigated the potential antifungal activity of four cinnamate derivatives including cinnamic acid, -coumaric acid, caffeic acid, and ferulic acid against . Our in vitro findings showed that all tested compounds exhibited dose-dependent fungistatic action against when their concentrations were increased from 0.

Lithium-ion batteries (LIBs) have become a hot topic worldwide because they are not only the best alternative for energy storage systems but also have the potential for developing electric vehicles (EVs) that support greenhouse gas (GHG) emissions reduction and pollution prevention in the transport sector. However, the recent increase in EVs has brought about a rise in demand for LIBs, resulting in a substantial number of used LIBs. The end-of-life (EoL) of batteries is related to issues including, for example, direct disposal of toxic pollutants into the air, water, and soil, which threatens organisms in nature and human health.

The aqueous extract of kava () root is known as a traditional beverage for daily intake in the Western Pacific Islands, such as Fiji, Tonga, and Vanuatu, to induce relaxation and health-beneficial effects. In this study, the antioxidant, anti-hyperuricemia, and antibacterial properties of kava root were investigated through the isolation and purification of bioactive compounds in ten fractions separated by column chromatography (CC). They included six flavonoids, 5-hydroxy-4',7-dimethoxyflavanone (), matteucinol (), isosakuranetin (), 5,7- dimethoxyflavanone (), 2',4'-dihydroxy-6'-methoxydihydrochalcone (in ) and alpinetin (), and seven kavalactones, 5,6-dehydrokawain (DK) (in and ), kavain (in ), yangonin (in and ), dihydro-5,6-dehydrokavain (DDK) (in ), 7,8-dihydromethysticin (in ), dihydromethysticin (in ), methysticin (in ).

Aluminum, arsenic, cadmium, chromium, cobalt, copper, iron, lead, mercury, nickel, thallium, titanium, zinc, carbon tetrachloride, phthalates, glyphosate, alcohol, drugs, and herbs are under discussion having the potential to injure the human liver, but allocation of the injury to the hepatotoxicant as exact cause is difficult for physicians and requires basic clinical knowledge of toxicology details. Liver injury occurs at a variable extent depending on the dose, mostly reproducible in animal models that allow studies on molecular steps leading to the hepatocellular injury. These exogenous hepatotoxins may cause an overproduction of reactive oxidative species (ROS), which are generated during microsomal or mitochondrial oxidative stress from incomplete oxygen split and trigger the injury if protective antioxidant capacities are reduced.

Article Synopsis
  • This study investigates how momilactones A and B (MA and MB) kill cancer cells in acute promyelocytic leukemia (APL) and multiple myeloma (MM) cell lines.
  • The research shows that MB and a mixture of MA and MB are highly effective against HL-60 and U266 cells, comparable to established cancer drugs like doxorubicin and ATRA.
  • The mechanism involves inducing apoptosis in cancer cells through specific pathways and protein interactions, while sparing non-cancerous cells, indicating momilactones' potential as a basis for new cancer treatments.

  • * The study tested two chalcone derivatives, DMAPAPP and its ruthenium III complex (Ru-DMAPAPP), which showed strong antifungal activity and reduced disease symptoms in pepper plants.
  • * Both compounds not only boosted the growth of pepper plants without causing harm but also triggered various antioxidant mechanisms and gene expressions that enhance the plants' defense against the fungus.

is widely distributed in tropical and subtropical countries and is traditionally used for preventing numerous disorders. In this study, a bioguided fractionation of ethyl acetate extract (SE) from root was carried out to target antioxidant and cytotoxic activities. Of the four fractions (SE1-SE4) obtained by column chromatography, SE4 had the strongest anti-radical ability in the DPPH and ABTS assays (IC = 0.

Saturated and unsaturated pyrrolizidine alkaloids (PAs) are present in more than 6000 plant species growing in countries all over the world. They have a typical heterocyclic structure in common, but differ in their potential toxicity, depending on the presence or absence of a double bond between C1 and C2. Fortunately, most plants contain saturated PAs without this double bond and are therefore not toxic for consumption by humans or animals.

Background: Vietnam possesses a vast diversity of rice landraces due to its geographical situation, latitudinal range, and a variety of ecosystems. This genetic diversity constitutes a highly valuable resource at a time when the highest rice production areas in the low-lying Mekong and Red River Deltas are enduring increasing threats from climate changes, particularly in rainfall and temperature patterns.

Results: We analysed 672 Vietnamese rice genomes, 616 newly sequenced, that encompass the range of rice varieties grown in the diverse ecosystems found throughout Vietnam.

The risk of liver injury associated with the use of herbal medicinal products (HMPs) is well known among physicians caring for patients under a HMP therapy, as documented in case reports or case series and evidenced by using the Roussel Uclaf Causality Assessment Method (RUCAM) to verify a causal relationship. In many cases, however, the quality of HMPs has rarely been considered regarding potential culprits such as contaminants and toxins possibly incriminated as causes for the liver injury. This review aims to comprehensively assemble details of tentative hepatotoxic contaminants and toxins found in HMPs.

fruit is commonly used for food ingredients and traditional medicines in tropical countries, however, information about its biological activities and chemical profiles has been inadequately reported. In this study, a bio-guided fractionation of antioxidants and α-amylase inhibitors from hexane (MH) and ethyl acetate (ME) extracts of fruit (pericarp and seed) was carried out. Eleven fractions from MH (D1-D11) and 17 fractions from ME (T1-T17) were obtained from column chromatography over silica gel, which were then examined for anti-radical capacity by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays, and pancreatic α-amylase inhibition, a key enzyme linked to type 2 diabetes.
