PROBLEM: Question: Does monocyte chemoattractant protein-1 or macrophage inflammatory protein-1alpha deficiency affect angiotensin II-induced intimal hyperplasia in carotid artery ligation model?
Answer: These results indicate that MCP-1 or MIP-1alpha may not be essential in mediating the proliferative effects of Ang II, a major pathological changes in intimal hyperplasia in the carotid artery ligation model.

SOLUTION: no

PROBLEM: Question: Does variation in the gene for human peroxisome proliferator activated receptor gamma ( PPARgamma ) play a major role in the development of morbid obesity?
Answer: Variation in the PPARgamma gene is unlikely to play a major role in the development of morbid obesity.

SOLUTION: no

PROBLEM: Question: Is the C282Y mutation of the HFE gene found in Chinese haemochromatotic patients : multicentre retrospective study?
Answer: The classical form of human leukocyte antigen-linked hereditary haemochromatosis appears to be absent form this locality. The H63D mutation is found in a minority (9.8%) of the patients, in whom it may act synergistically with an erythropoietic factor.

SOLUTION:
