in the course of the present study, samples were taken from the non-defoliant strain of verticillium dahliae (ss-4) from infected olive groves in toshan area in southern gorgan. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and after identification was reaned on tomato seedlings cv. rutgers. during the study, one-year-old seedlings of olive cultivars zard...

embryonic stem cells (escs) are undifferentiated cells which are typically derived from the inner cell mass of a blastocyst-stage embryo. in culture, these cells have the capacity to self-renew in an undifferentiated state but also may differentiate into cell types representing the three embryonic germ lineages, thus revealing their pluripotent potential. these cells could be of value for creat...

Isohemigossypolone (1) and 2-O-methylisohemigossypolone (2), major fungitoxins of Pachira aquatica, were found to accumulate locally in the outer bark of the swollen trunk, whereas the inner bark and heartwood contained only a trace amount of them. From P. aquatica that was infected with a phytopathogenic bacterium, we detected significant amounts of 1 and 2 from browned inner tissues of the sw...

Browning is the result of appearance of dark colored pigments formed by enzymatic and non enzymatic reactions. In this review AA, first overview the biochemistry of browning and fruits response and protection, successively touch the topic in the lightly processed fruits. Non enzymatic reaction is mainly due to Maillard reaction compounds in which concentration of amino acid (nitrogen supply) an...

enzymatic browning and formation of brown pigments are some of the most important problems in preparation of mushroom purees. in this study, the effect of some anti browning agents including sodium metabisulphite, ascorbic acid, and citric acid on the whiteness and foaming properties of mushroom purees was investigated. the results showed that soaking with acids and sodium metabisulphite signif...

Visceral adiposity is much more strongly associated with cardiometabolic disease in humans than subcutaneous adiposity. Browning, the appearance of brown-like adipocytes in the white adipose tissue (WAT), has been shown to protect mice against metabolic dysfunction, suggesting the possibility of new therapeutic approaches to treat obesity and type 2 diabetes. In mice, subcutaneous WAT depots ex...

Stem cells in the nervous system have some capacity to restore damaged tissue. Proliferation of stem cells endows them with self-renewal ability and accounts for in vitro formation of neurospheres, clonally derived colonies of floating cells. However, damage to the nervous system is not readily repaired, suggesting that the stem cells do not provide an easily recruited source of cells for regen...

fruit browning and tissue softening due to damages during handling, quality losses and water loss are the major limiting factors reducing postharvest life of early ripening apples. in this study, the effect of salicylic acid (sa) on fruit quality of apple cv ‘golabe-kohanz’ during postharvest life were investigated. harvested fruits were immersed in zero, one, two and four mm sa and were mainta...
