The flavanones naringenin and hesperetin exhibit estrogenic, anticarcinogenic and antioxidative properties. Orange juice and grapefruit juice contain high amounts of these compounds, and therefore their intake from the diet can be relatively high. No data are available regarding plasma concentrations or plasma kinetics of flavanones. The objectives of this study were to develop methods allowing...

Investigations at this and other stations have shown generally that nitrogenous fertilizers exert considerable influence in increasing the yields of grapefruit and other citrus fruits. The factors affecting quality of grapefruit and the relation of nitrogen nutrition to quality have not yet been fully studied with the result that orchard management practices, particularly in Arizona, cannot be ...

Cranberry juice is used routinely, especially among women and the elderly, to prevent and treat urinary tract infections. These individuals are likely to be taking medications concomitantly with cranberry juice, leading to concern about potential drug-dietary substance interactions, particularly in the intestine, which, along with the liver, is rich in expression of the prominent drug metaboliz...

The capacity of the alternative respiratory pathway increased in the flavedo tissue of ;Marsh' grapefruit (Citrus paradisi Macf.) stored at 5 degrees C for 2 weeks or longer. Elevated O(2) levels during respiratory assays enhanced respiration by the tissue at 20 degrees C but not at 5 degrees C. At 20 degrees C, salicylhydroxamic acid alone was inhibitory to O(2) uptake only in elevated O(2). I...

A kind of surface plasmon resonance sensor based on grapefruit photonic crystal fiber (PCF) filled with different numbers of silver nanowires has been studied in this paper. The surface plasmon resonance modes and the sensing properties are investigated comprehensively using the finite element method (FEM). The simulation results show that the intensity sensitivity is related to nanowire number...

Plants have been used throughout human history for their medicinal properties and herbal medicines are popular worldwide. Since, all herbal medicines are mixtures of more than one active ingredient, such combinations of many substances obviously increase the likelihood of interactions taking place. Although herbal medicines have been used as remedies for number of illnesses, many of them have s...

Orange (Citrus sinensis) and grapefruit (Citrus paradise) peels were used as a source of pectin, which was extracted under different conditions. The peels are used under two states: fresh and residual (after essential oil extraction). Organic acid (citric acid) and mineral acid (sulfuric acid) were used in the pectin extraction. The aim of this study is the evaluation the effect of extraction c...

A 65-year-old male with documented atrial flutter who was taking warfarin chronically returned to the anticoagulation clinic for follow-up, after having been on 10 mg daily for approximately 2 weeks. He had a previous sub-therapeutic international normalized ratio of 1.7 on a dose of 65 mg/week. The international normalized ratio at this visit was now 4.77 via venipuncture, after just an 8% inc...

Some phytosanitary irradiation treatment research against tephritid fruit flies (Diptera: Tephritidae) has used artificially infested fruit with the unstated and untested assumption that the method adequately simulated a natural situation. We compare grapefruit, Citrus paradisi Macfayden, naturally infested by Mexican fruit fly, Anastrepha ludens (Loew), via oviposition until larvae reached the...

The content of certain ingredients of human milk, such as flavonoids, depend on the types and amounts of plant products consumed and may vary from woman to woman. The aim of the study was to determine to what extent consumption of an average amount of grapefruit juice (250 ml) affected naringenin content in human milk. A total of 14 breastfeeding mothers were included in the study. The subjects...
