Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health, leading to reduced life. New study of researchers has revealed the new fact the obesity will trigger the tumour formation. The in vivo studies on obese and lean rats which were feed with same food have proved that the obese conditions are much prone to tumour formation. In the obese patients the fat called adipose tissue is present in huge amount and will extend much sooner than lean. These adipose tissue cells gradually divide and lead to the cancer induced stromal cells which navigate to the circulatory system and leads to the formation of fat cells and also tumour associated blood vessels. The tumour associated blood vessels support the growth of tumour by diverting more oxygen and nutrients to tumour cells which rigorously grow than normal cells and lead to advanced cancer in no time. The existence of these path ways are still emerging concepts and the understanding of these signalling pathways will definitely open a new avenue for the cancer treatments and cell therapies.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
