BACKGROUND Bryopsis hypnoides Lamouroux is a siphonous green alga, and its extruded protoplasm can aggregate spontaneously in seawater and develop into mature individuals. The chloroplast of B. hypnoides is the biggest organelle in the cell and shows strong autonomy. To better understand this organelle, we sequenced and analyzed the chloroplast genome of(More)
The cell organelles of the coenocytic alga Codium fragile (Sur.) Hariot aggregated rapidly and protoplasts were formed when its protoplasm was extruded out in seawater. Continuous observation showed that there were long and gelatinous threads connecting the cell organelles. The threads contracted, and thus the cell organelles aggregated into protoplasmic(More)
OBJECTIVE To compare the instructive value of the 6th and 7th editions of the UICC-AJCC staging system in prognosis of esophageal cancer (EC) patients. METHODS The staging and prognosis of 1397 esophageal carcinoma patients undergoing curative resection from Jan. 2003 to Dec. 2006 in our hospital were retrospectively reviewed and analyzed according to the(More)
The photosynthetic oxygen evolution of Caulerpa serrulata was determined with oxygen electrodes. The effects of light and temperature on the growth and regeneration of fragmented C. serrulata thalli were analyzed. The regenerating rate and establishment of different sizes and portions of C. serrulata were studied. The results showed that the light(More)
In distributed simulation, there is no uniform physical clock. And delay cannot be estimated because of jitter. So simulation time synchronization is essential for the event consistency among nodes. This paper investigates time synchronization algorithms over large-scale distributed nodes, analyzes LBTS (lower bound time stamp) computation model described(More)
OBJECTIVE To compare the short-term outcomes of surgical treatment for non-small cell lung cancer (NSCLC) by video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT). METHODS Data of 737 consecutive NSCLC patients who underwent surgical treatment for non-small cell lung cancer by video-assisted thoracoscopic surgery and 630 patients who(More)
The applications of chiral drugs had a profound impact on human health. With the development of disciplines of chemistry, materials and life science, the research on the separation and analysis of chiral drugs became intensified. Chromatography and the selection of chiral stationary phase played important roles in resolving chiral drugs. The optimization of(More)
Objective To investigate the relationship between geranylgeranyl pyrophosphate synthase (GGPPS) gene polymorphisms and bone response to alendronate in Chinese osteoporotic women.Methods A total of 639 postmenopausal women with osteoporosis or osteopenia were included and randomly received treatment of low dose (70 mg per two weeks) or standard dose (70 mg(More)
OBJECTIVE To analyzed the indication and prognostic factors of surgical treatment of lung cancer invading left atrium and great vessels (T4). METHODS We retrospectively reviewed the database of 136 T4 lung cancer (tumors invading left atrium and great vessels) patients who received surgical treatment in Cancer Hospital of Chinese Academy of Medical(More)
