A. R. Collins explained that damage to DNA was the originating event in the process of carcinogenesis. “The damage can be caused by environmental or endogenous (produced within the body) processes, and oxidative damage caused by reactive oxygen molecules released during cellular respiration is thought to make a significant contribution.

in vitro assessment of the antifungal activities was evaluated in the present study for both aqueous and ethanol extracts prepared from leaves of avicennia marina and rhizophora mucronata . leaves of mangrove species were collected from qeshm and syrik of south-east coast of iran, mangrove forest respectively. antimicrobial tests were carried out through disk diffusion method. minimum fungicida...

Mango, a tropical fruit of great economic importance, is generally harvested green and then commercialised after a period of storage. Unfortunately, the final quality of mango batches is highly heterogeneous, in fruit size as well as in gustatory quality and postharvest behaviour. A large amount of knowledge has been gathered on the effects of the maturity stage at harvest and postharvest condi...

After rice and wheat, Potato (Solanum tuberosum L.) is the third most important food crop worldwide and provides high quality nutrition, especially food energy, vitamin C, potassium, protein and dietary fiber [1,2]. Due to their short production cycle, potatoes provide food faster than cereals or legumes and produce more food calories per hectare, and use less water as compared to either wheat ...

Pitaya is one of the most important commercial cactus fruit. Pitaya fruits are easy to get injury during postharvest handling and storage. Pre-harvest and postharvest calcium treatments have been used to maintain flesh firmness and extend shelf life of many fruits. The aim of this study was to evaluate the effects of calcium treatments on maintaining pitaya fruit quality during cold storage. Pi...

Postharvest green mold, caused by the pathogen Penicillium digitatum (Pers.:Fr.) Sacc., is the most economically important postharvest disease of citrus fruits in Spain, areas with Mediterranean climate, and citrus production areas worldwide characterized by low summer rainfall. Economic losses due to this disease have been typically reduced through the application of synthetic chemical fungici...

This study analyses how the level of postharvest technology’s development influences the economic efficiency of apple production with the help of a deterministic simulation model based on primary data gathering in producer undertakings. To accomplish our objectives and to support our hypotheses three processing plant types are included in the model: firstly apple production with no postharvest ...

Hydrogen sulfide (H2S) has been identified as an important gaseous signal in plants. Here, we investigated the mechanism of H2S in alleviating postharvest senescence and rotting of Kyoho grape. Exogenous application of H2S released from 1.0 mM NaHS remarkably decreased the rotting and threshing rate of grape berries. H2S application also prevented the weight loss in grape clusters and inhibited...
