For centuries, Aloe Vera has been used by many different cultures. The ancient Greeks, the Romans, the Babylonians, Indians and the Chinese have all used Aloe Vera as a medicinal plant. One of the common experimental cancer models is sarcoma-180. When Aloe was administered to mice bearing S-180 tumors, the tumor growth was inhibited. Aloe vera is a dietary supplement and not a regulated drug. T...

The transformation of normal plant tissue into tumor tissue occurs in three steps, which have been designated conditioning, induction, and promotion.' Conditioning is accomplished by substances present in the wound juice; induction by a tumorinducing principle (T-iP) produced by virulent Agrobacterium tumefaciens grown in unheated plant juice; and promotion, by indoleacetic acid or its physiolo...

The basidiomycete Ustilago maydis causes smut disease in maize, with large plant tumors being formed as the most prominent disease symptoms. During all steps of infection, U. maydis depends on a biotrophic interaction, which requires an efficient suppression of plant immunity. In a previous study, we identified the secreted effector protein Pit2, which is essential for maintenance of biotrophy ...

Agrobacterium tumefaciens infects plants and induces the formation of tumors called "crown galls" by integrating the transferred-DNA (T-DNA) region of the Ti-plasmid into the plant nuclear genome. Tumors are formed because the T-DNA encodes enzymes that modify the synthesis of two plant growth hormones, auxin and cytokinin (CK). Here, we show that a CK biosynthesis enzyme, Tmr, which is encoded...

between i 9h i and 1993,30 cases of primary cardiac tumors were diagnosed at the imam khomeini hospital. 20 patients were female and 10 were male, with an average age of 32 years (ranging from 17 days to 65 years of age). the mean duration of symptoms before diagnosis was 6 months, with dyspnea and palpitation being the most common symptoms (60%) and cardiac' murmurs the most usual signs (...

purpose: to assess the histopathological and immunohistochemical features of orbital spindle cell tumors. methods: a descriptive, retrospective study was performed on 63 pathology reports on all types of orbital spindle cell tumors at the pathology department of farabi hospital between 1995 and 2005. immunohistochemistry studies for different markers, such as smooth muscle actin, desmin, s100 p...

As a special phytopathogen, Agrobacterium tumefaciens infects a wide range of plant hosts and causes plant tumors also known as crown galls. The complexity of Agrobacterium-plant interaction has been studied for several decades. Agrobacterium pathogenicity is largely attributed to its evolved capabilities of precise recognition and response to plant-derived chemical signals. Agrobacterium perce...
