Grape juice, in addition to being an energetic food, due to its high sugar content, has several compounds that can prevent or treat various types of diseases. Resveratrol is a compound present in grapes that has attracted a lot of interest; in addition to preventing cardiovascular disease linked to lipid metabolism, it has chemopreventive and chemotherapeutic activities. We evaluated the antimu...

Thioredoxins (Trxs) are small ubiquitous disulfide reductases that participate in dithiol-disulfide exchange reactions. In contrast to animals and prokaryotes that typically possess one or a few genes encoding Trxs, higher plants contain eight different Trx types: f, m, x, y, z, o, s, and h. Trx h with multiple forms is involved in different processes such as seed germination, cellular protecti...

The main effects of three different irrigation regimes, i.e., sustained deficit irrigation (SDI), regulated deficit irrigation (RDI) and non-irrigated (NI), on seed traits namely proanthocyanidins (PAs) were evaluated in the wine grape cultivar Aragonez (syn. Tempranillo) grown in Alentejo (Portugal) over two growing seasons. Results showed that while the number of seeds per berry was not affec...

BACKGROUND The phytohormone gibberellic acid (GA3) is widely used in the table grape industry to induce seedlessness in seeded varieties. However, there is a paucity of information concerning the mechanisms by which GAs induce seedlessness in grapes. METHODOLOGY/PRINCIPAL FINDINGS In an effort to systematically analyze the cause of this GA3-induced seed abortion, we conducted an in depth char...

Background: Cylophosphamide is used alone or in combination with other drugs for treatment of neoplastic diseases. Hemorrhagic cystitis is a major potential toxicity and dose limiting side effect of cyclophosphamide. The aim of this study was to evaluate the effects of lycopene compared with some antioxidants for the prevention of cyclophosphamide induced hemorrhagic cystitis in rats. Methods: ...
