There is an inverse relationship between tumor stage and metastasis and nm23H1 expression in individuals with prostate carcinomas and a similar relationship exists between microsatellite instability of the nm23H1 gene and ovarian carcinogenesis.For instance,nearly 70.5%of stageⅠ-Ⅱovarian tumors express nm23H1 in sharp contrast to only 25%of stageⅢ-Ⅳovarian tumors.As is clearly evident,nm23H1 has a major role in gastrointestinal and non-gastrointestinal carcinogenesis.The coming few years will hopefully see the development of new strategies by virtue of which we can alter nm23H1 expression and thus decrease the risk of metastasis in malignant tumors.展开更多

N. sativa is of immense therapeutic benefit in diabetic individuals and those with glucose intolerance as it accentuates glucose-induced secretion of insulin besides having a negative impact on glucose absorption from the intestinal mucosa. N. sativa administration protects hepatic tissue from deleterious effects of toxic metals such as lead, and attenuates hepatic lipid peroxidation following exposure to chemicals such as carbon tetrachloride.展开更多

The authors have clearly shown that triptolide administration is associated with upregulation of the Bax gene, resulting in an attenuating effect on cell growth in gastrointestinal malignancies such as pancreatic carcinomas. The article by Zhou et al is all the more important because it highlights the rapidly increasing role of triplodide in the management of systemic malignancies. For instance, triptolide acts on the PI3K/Akt/NF-κB pathway, thereby enhancing apoptosis secondary to the administration of bortezomib in multiple myeloma cells. Similar synergisms are seen when triptolide is administered along with 5-fluoruracil for the management of colonic carcinomas. Similarly, triptolide causes down-regulation of the Bcl-2 gene, resulting in control of cell growth in tumors, such as glioblastoma multiformes.展开更多

To mitigate the performance degradation caused by the use of antenna selection that is based on correlation among columns, an iterative receiver scheme that uses only a subset of the constellation points close to the expected symbol vahle estimated in the previous iteration is proposed. The size of the subset can adapt to the maximum correlation of the sub-matrix after the simple antenna selection. Furthermore, the error rate performance of the scheme under linear Miniinutn Mean Square Error （MMSE） or Ordered Successive Interference Cancellation （OSIC） for the first run detection and different interleaver lengths is investigated while the transnlit antenna selection is considered. The simulation results show a significant advantage both for implementation complexity and for error rate performance under a fixed data rate.展开更多

The authors have clearly demonstrated the efficacy of CD40 ligand gene therapy in inhibiting the growth of hepatocellular carcinomas. The findings of Jiang et al.（2009） are highly important as they further support and corroborate the rapidly expanding role of CD40 ligand gene therapy in the management of systemic malignancies besides hepatocellular carcinomas.展开更多

Lubiprostone also seems to improve visualization of the gastrointestinal tract during procedures such as colonoscopy.This is especially true if the lubiprostone is administered prior to bowel cleansing with agents such as polyethylene glycol electrolyte(PEG-E). Lubiprostone also enhances and stimulates contraction in colonic as well as gastric muscles and may thus further contribute as a prokinetic agent.Besides these effects,lubiprostone also causes hyperpolarization in other tissues such as uterine muscle cells.This may prove to be of significant clinical benefit in the management of uterine pathologies in the near future.展开更多
