Anti-endostatin antibody treatment resulted in significantly higher mortality of MI rats than controls. The
MI rats with endostatin neutralization displayed adverse LV remodeling selleck products and severe heart failure compared with control MI rats. Although angiogenesis was increased, tissue remodeling and interstitial fibrosis were further exaggerated in post-MI hearts by endostatin neutralization. Furthermore, the expression and protease activity of matrix metalloproteinases -2 and -9, and of angiotensin-converting enzyme were markedly elevated by endostatin neutralization.\n\nConclusions: Neutralization of endostatin worsens the symptoms and outcomes of MI in a rat model. The results imply that endogenous endostatin/collagen XVIII may suppress aberrant LV remodeling G418 inhibitor and heart failure after MI. (Circ J 2010; 74: 109-119)”
“Glycine betaine (GB) is an important osmolyte synthesized in response to different abiotic stresses, including salinity. The
two known pathways of GB synthesis involve: 1) two step oxidation of choline (choline -> betaine aldehyde -> GB), generally found in plants, microbes and animals; and 2) three step methylation of glycine (glycine -> sarcosine -> dimethylglycine -> GB), mainly found in halophilic archaea, sulphur bacteria and the cyanobacterium Aphanothece (A p.) halophytica. Here, we transformed a salt-sensitive freshwater diazotrophic filamentous cyanobacterium Anabaena (An.) doliolum with N-methyltransferase genes (ApGSMT-DMT) from Ap. halophytica using the triparental conjugation method. The transformed An. doliolum synthesized
and accumulated GB in cells, and showed increased salt tolerance and protection to nitrogenase activity. The salt responsiveness of the transformant was also apparent as GB synthesis increased with increasing concentrations of NaCl in the nutrient solution, and maximal [12.92 mu mol (g dry weight)(-1)] in cells growing at 0.5 M NaCl. Therefore, the transformed cyanobacterium has changed its behaviour from preferring freshwater to halophily. This study may have important biotechnological implications for the development of stress tolerant nitrogen-fixing cyanobacteria as biofertilizers for sustainable agriculture.”
“Large cell neuroendocrine carcinoma (LCNEC) buy SB525334 of the lung is a rare and aggressive tumour with a poor prognosis. Lung cancer metastases to the prostate are also uncommon, and are usually found incidentally during autopsy. Most reported primary lung cancers with prostatic metastases are small cell carcinomas, and prostatic metastases from LCNEC of the lung have not been reported previously. This case report describes a 70-year-old man with LCNEC of the lung and metastases in the prostate, brain, bone, liver and lymph nodes.”
“Background: One of the novel techniques utilizing fine needle aspiration (FNA) in the diagnosis of mediastinal and lung lesions is the endobronchial ultrasound (EBUS)-guided FNA.
