OBJECTIVE Primary papillary serous carcinoma (PPSC) of the cervix is rarely recognized, with the aggressive and unpredictable course. Here we report a case of primary adenosquamous papillary serous carcinoma of the cervix in a woman who underwent comprehensive treatment. CASE A 53-year-old woman presented with irregular vaginal bleeding in hospital. The(More)
BACKGROUND MircoRNAs(miRNAs) are short, endogenously non-coding RNAs. The abnormal expression of miRNAs may be valuable for the diagnosis and treatment of tumors. METHODS To screening the special miRNAs in gastric carcinoma, expression level of miRNAs in gastric carcinoma and normal gaster samples were detected by miRNA gene chip. Then, the expressions of(More)
(S)-ZJM-289, a novel nitric oxide (NO)-releasing derivative of 3-n-butylphthalide, induces the neuroprotection in a rat model of focal cerebral ischemia/reperfusion (I/R). However, much is unknown about the late phase effect in the neuroprotection of (S)-ZJM-289 preconditioning. The purpose of this study is to explore the late phase neuroprotection of(More)
High seed vigor is important for agricultural production due to the associated potential for increased growth and productivity. However, a better understanding of the underlying molecular mechanisms is required because the genetic basis for seed vigor remains unknown. We used single-nucleotide polymorphism (SNP) markers to map quantitative trait loci (QTLs)(More)
In this research, we introduce a new heuristic approach using the concept of ant colony optimization (ACO) to extract patterns from the chromosomes generated by previous generations for solving the generalized traveling salesman problem. The proposed heuristic is composed of two phases. In the first phase the ACO technique is adopted to establish an archive(More)
The 26S proteasome is a large multisubunit proteolytic complex, regulating growth and development in eukaryotes by selective removal of short-lived regulatory proteins. Here, it is shown that the 26S proteasome and the transcription factor gene REVOLUTA (REV) act together in maintaining inflorescence and floral meristem (IM and FM) functions. The(More)
BACKGROUND The healthcare system of mainland China is undergoing drastic reform and the optimal models for healthcare financing for provision of primary care will need to be identified. This study compared the performance indicators of the community health centres (CHCs) under different healthcare financing systems in the six cities of the Pearl River Delta(More)
BACKGROUND Strengthening primary care is key to Hong Kong's ongoing health system reform. Primary care remains unregulated, private sector dominated and financed mainly out-of-pocket. This study sought to examine the association between patients' socioeconomic status (SES), source of health payments and the quality of primary care they accessed to inform(More)
Generation of functional spermatids from azoospermia patients is of unusual significance in the treatment of male infertility. Here, we report an efficient approach to obtain human functional spermatids from cryptorchid patients. Spermatogonia remained whereas meiotic germ cells were rare in cryptorchid patients. Expression of numerous markers for meiotic(More)
Colorectal cancer is one of the most common and fatal tumors. However, molecular mechanisms underlying carcinogenesis of colorectal cancer remain largely undefined. Here, we explored the expression and function of Nodal in colon cancer stem cells (CCSCs). Nodal and its receptors were present in numerous human colorectal cancer cell lines. NODAL and ALK-4(More)
