a r t i c l e i n f o a b s t r a c t To estimate the future development of one technology and make decisions whether to invest in it or not, one needs to know the current stage of its technology life cycle (TLC). The dominant approach to analysing TLC uses the S-curve to observe patent applications over time. But using the patent application counts alone(More)
BACKGROUND Lysosome-associated protein transmembrane 4 beta (LAPTM4B) has two alleles named LAPTM4B*1 and LAPTM4B*2. Allele *1 contains only one copy of a 19-bp sequence at the 5'UTR in the first exon, whereas this sequence of allele*2 is duplicated and arrayed as a tandem repeat. Previous studies revealed that LAPTM4B polymorphisms contribute to the risk(More)
Interleukin-12 (IL-12), a member of interleukin family, plays a critical role in immune responses and anti-tumor activity. In this study, the effects of IL-12 on monocytic tumor cell lines differentiation to macrophagocyte and its likely mechanism was investigated. We examined the differentiation markers, morphological and functional changes, and possible(More)
AIM To assess the correlation between mammographic features and clinicopathologic characteristics of invasive breast carcinoma. PATIENTS AND METHODS The mammographic appearance and clinicopathological data of 108 invasive ductal carcinomas were retrospective analyzed. The mammographic features were assessed according to BI-RADS by two doctors. Estrogen(More)
Recognized as ubiquitous contaminants in soil, the environmental risk of phthalic acid esters (PAEs) is of great concern recently. Effects of di-n-butyl phthalate (DnBP), an extensively used PAE compound to Eisenia fetida have been investigated in spiked natural brown yellow soil (Alfisol) for soil contact test. The toxicity of DnBP to E. fetida on the(More)
Congenital and progressive hearing impairment is a common distressing disease. The progressive dominant hearing loss DFNA28 in human is associated with a frameshift mutation of Grainyhead-like 2 (GRHL2) but its etiology and mechanism remain unknown. Here we report a zebrafish grhl2b(T086) mutant line in which grhl2b expression is interrupted by an insertion(More)
A novel carotenoid 1,2-hydratase (CruF) responsible for the C-1',2' hydration of gamma-carotene was identified in the non-photosynthetic bacteria Deinococcus radiodurans R1 and Deinococcus geothermalis DSM 11300. Gene expression and disruption experiments demonstrated that dr0091 and dgeo2309 encode CruF in D. radiodurans and D. geothermalis, respectively.(More)
The impact of postoperative complications (POCs) on long-term survival outcomes following hepatic resection for colorectal liver metastasis (CRLM) is in controversy. The aim of the present meta-analysis was to systematically evaluate the POC effect on overall survival (OS) and disease-free survival (DFS) in patients undergoing hepatic resection for CRLM. We(More)
Little is known about how patterns of DNA methylation change during mammalian spermatogenesis. 5 hmC has been recognized as a stable intermediate of DNA demethylation with potential regulatory functions in the mammalian genome. However, its global pattern in germ cells has yet to be addressed. Here, we first conducted absolute quantification of 5 hmC in(More)
OBJECTIVE To discuss the results of a multicenter randomized controlled trial of the efficacy of verum acupuncture in treating acute migraine attacks. BACKGROUND Acupuncture has been used in China for centuries to treat migraine headache. Convincing evidence of its efficacy in alleviating pain, however, has been inadequate to date. METHODS A total of(More)
