Modelling chlorophyll fluorescence of kiwi fruit (Actinidia deliciosa).

Summary of "Modelling chlorophyll fluorescence of kiwi fruit (Actinidia deliciosa)."

Kiwi fruit displays chlorophyll fluorescence. A physical model was developed to reproduce the observed original fluorescence for the whole fruit, from the emission of the different parts of the kiwi fruit. The spectral distribution of fluorescence in each part of the fruit, was corrected to eliminate distortions due to light re-absorption and it was analyzed in relation to photosystem II-photosystem I ratio. Kiwi fruit also displays variable chlorophyll-fluorescence, similar to that observed from leaves. The maximum quantum efficiency of photosystem II photochemistry (F(v)/F(m)), the quantum efficiency of photosystem II (Φ(PSII)), and the photochemical and non-photochemical quenching coefficients (q(P) and q(NP) respectively) were determined and discussed in terms of the model developed. The study was extended by determining the photosynthetic parameters as a function of the storage time, at both 4 °C and room temperature for 25 days.

Kiwi fruit (Actinidia deliciosa) ameliorates gentamicin-induced nephrotoxicity in albino mice via the activation of Nrf2 and the inhibition of NF-κB (Kiwi & gentamicin-induced nephrotoxicity).

Gentamicin is a potent aminoglycoside antibiotic, but the risk of nephrotoxicity limits its prolonged use. The toxicity of gentamicin is believed to result from oxidative stress, a condition that coul...

Medical and Biotech [MESH] Definitions

A plant family of the order Theales, subclass Dilleniidae, class Magnoliopsida. It is best known for Kiwi fruit (ACTINIDIA).

Measurement of the intensity and quality of fluorescence.

An analytical method for detecting and measuring FLUORESCENCE in compounds or targets such as cells, proteins, or nucleotides, or targets previously labeled with FLUORESCENCE AGENTS.

Widely distributed unicellular or multicellular bacteria. The CYANOBACTERIA use chlorophyll a and phycobilins for oxygenic photosynthesis while genera in the Prochlorales use both chlorophyll a and b but not phycobilins.

A type of FLUORESCENCE SPECTROSCOPY using two FLUORESCENT DYES with overlapping emission and absorption spectra, which is used to indicate proximity of labeled molecules. This technique is useful for studying interactions of molecules and PROTEIN FOLDING.
