Common Names: wine grape
This study assessed whether a nutraceutical blend of alpha lipoic acid, Vitis vinifera, and Ginkgo biloba can work alongside Avanafil therapy.
Grapes of different varieties respond differently to heat and drought. Tempranillo is most affected while Grenache is more resilient. Understanding this helps optimize grape growth and wine quality amidst changing climate conditions.
Scientists studied how micro/nano-plastics (MNPs) are absorbed by grapevines. They found that polystyrene nanoparticles can be taken up by the root system and transported upwards. This research helps assess the risk of MNPs entering the food chain and provides data for plant health and ecological risk assessment.
SCG cream gel may improve range of motion and chronic pain in shoulder and elbow, reducing the need for traditional treatments with undesirable side effects. Consider using SCG as an alternative therapy for upper limb problems.
Researchers identified and purified phloroglucinol and total procyanidin dimer from seed extract, showing superior anti-diabetic effects in vitro by enhancing glucose uptake and suppressing oxidative stress. This natural remedy could offer a safe and economical alternative to current diabetes treatments.
NAA application delays grape ripening, increases β-damascenone and TDN, decreases IBMP, and triggers changes in norisoprenoid metabolisms through ABA and auxin signaling pathways. VvABF2 and VvARF10 are potential regulators. Important for improving grape quality.
Reducing nitrogen fertilizer application during grape growing seasons improves wine quality by enhancing phenolic compounds, including tannins and anthocyanins, and increasing individual stilbenes like piceatannol and trans-resveratrol.
The researchers analyzed the differences in phenolic compound concentrations in grapevine leaves infected with E. necator. This helps determine the susceptibility of different grapevine varieties to the disease and could lead to improved disease management and sustainable crop production.
Researchers found that a nano-conjugate of putrescine and chitosan improved the resistance of grapevines to cadmium stress, which could help protect crop productivity and human health.
Scientists found that the accumulation of certain metabolic products differs in red and white sections of variegated grapes. MYB24, a gene, regulates the synthesis of terpenes and flavonols, potentially affecting carotenoids. This study provides insights into the triggers and effects of variegation in berries.
The study analyzed patients with asymptomatic atherosclerosis and high arterial stiffness. Triple combination therapy with γ-linolenic acid, Vitis vinifera extract, and acetyl-L-carnitine reduced arterial stiffness in both sexes. Changes in blood glucose and lipid levels were not observed.
This study found that adding dried koruk pomace to kofte formulations can effectively decrease the levels of food-borne pathogens like O157:H7 and Typhimurium, especially at low contamination levels. Using dried koruk pomace can improve the safety of kofte products.
Vitis vinifera contains dietary stilbenoids that benefit neuronal disorders related to cognitive impairment. This study investigated the effects of vitisin A, a resveratrol tetramer derived from V. vinifera stembark, on cognitive functions. In in vitro and ex vivo experiments, vitisin A increased cell survival and restored synaptic mechanisms of learning and memory. In vivo experiments showed that vitisin A ameliorated memory function disruptions in mice and upregulated BDNF-CREB signaling in the hippocampus. Overall, vitisin A exhibits neuroprotective effects by upregulating BDNF-CREB signaling and LTP, making it a potential therapeutic agent for neurodegenerative disorders.
To avoid economic damage to the wine industry, accurate identification of grapevine cultivars is crucial. Researchers have developed morphological, molecular, and chemical tools for positive identification of grape varieties.
The neurodegenerative disease Alzheimer's currently has no complete cure, but flavones from L. have been found to promote synaptic plasticity and indirectly affect cholinergic neurotransmitters in a rat model. This study has potential implications for treating Alzheimer's disease.
Vine leaves contain bioactive compounds with antiviral properties against human pathogens. Researchers evaluated the phenolic composition and antiviral activity of leaf extract against Herpes simplex virus type 1 (HSV-1) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). HPLC-MS/MS analysis identified 40 phenolic compounds in the extract, including quercetin derivatives, luteolin, kaempferol, and apigenin. The extract inhibited both viruses at a low concentration of 10 μg/mL. These findings suggest natural extracts could be used in antiviral drugs and future vaccines.
