In order to identify sequence elements responsible for the regulation of mesophyll_specific expression, the 5′ flanking regions of -1 195 bp, -1 102 bp, -768 bp, and -644 bp upstream of the translation initiation ATG codon were fused to the reporter gene encoding β_glucuronidase (GUS) and transferred to rice via particle bombardment. Analysis of the 5′ promoter deletions identified that a 93 bp fragment between -1 195 bp and -1 102 bp is essential for directing mesophyll specific expression. High constitutive expression of GUS reporter gene was found in the -768 deletion lines and another two deletion series. These results indicate the great potential utility of the promoter in rice biotechnology.展开更多

Endoscopic therapy is less invasive and may represent an alternative to esophagectomy for superf icial esophageal carcinosarcoma. Here, we report a 61-year-old male who was diagnosed as esophageal carcinosarcoma and underwent endoscopic polypectomy with well tolerance and favorable prognosis. We also present a brief review of the literature.展开更多

Comparatively speaking, research on NE prediction is still limited and under development. Therefore, it is important to correctly assess NE for further study. In this study, an energy balance trial and a fasting metabolism trial were used to measure the net energy for production （NEp） and the net energy for maintenance （NEm）, respectively. Meanwhile, a backward method of multiple linear regression was applied to establish prediction equations for NE. The results showed that corn NE is about 2 times higher than that of soybean meal, due to the efficiency of ME （k） utilization by the ingredients. Meanwhile, AME and acid detergent fiber （ADF） were found to be better predictors for the NE of corn and soybean meal, respectively. Furthermore, Equations 1（R^2=0.993, RSD=0.0091） and 12 （R^2=0.999, RSD=0.0008） were found to be better prediction equations in multiple linear regression analyses for corn and soybean meal, respectively. However, considering the cost of the analytical procedures, the accuracy of the prediction （RSD）, and the additional variability or errors due to interlaboratory variance, Equation 4 （R^2=0.990, RSD=0.0109） and Equation 20 （R^2=0.996, RSD=0.0043） were better models for corn and soybean meal, respectively. Nevertheless, these equations for corn and soybean meal should be applied only under similar experimental conditions.展开更多

She develops multilayered meanings of the house in terms of psychological, spiritual, and sensory influences on both her private and communal life. She deploys sensory signiflers to portray religious and spiritual memories in a picturesque or performative way. The book reveals that the primacy of the senses as a perceptual device transforms the habitual religious rituals of popular Catholicism into the unconscious. This book shows how sensory perception is engaged in appropriating mystical space/time and interiorizing spiritual objects of family life. Thus, the paper investigates how the sensory agencies contribute to exploring culturally plural ways of experiencing the divine. It also illustrates how Mora＇s deployment of corporeality is related to her reassessment of femaleness and understanding of a meaning of the divine, which is distinctively embodied through 1o cotidiano. In effect, it focuses on Mora＇s treatment of the sensible body in connection with spiritual and religious connotations.展开更多

METHODS: We performed a systematic review and meta-analysis of Chinese literature by searching the Chinese Biomedical Database and Chinese scientific Journals database (up to March 2008). All cohort studies (controlled or uncontrolled) in which the patients were observed for more than a year were reviewed in detail. Dichotomous outcomes were reported as relative risks (RR) with 95% confidence interval (CI) for controlled trials. The efficacy in uncontrolled trials was assessed by a pooled estimate of response rate with individual studies weighted in proportion to the sample size. RESULTS: Seven controlled trials compared the effect of botulinum toxin injection (BoTx) with pneumatic dilation (PD). PD was superior to BoTx [65.2% vs 45.3%; RR 1.47 (95% CI 1.23-1.77), P < 0.0001], and had a lower clinical relapse rate (BoTx 30.2% vs PD 10%, RR 0.32 (0.16-0.65), P = 0.001). Heller myotomy (HM) had superior remission rate compared to PD [HM 94.0% vs PD 64.1%, RR 1.48 (1.15-1.99), P = 0.002]. In uncontrolled trials, the effectiveness of PD was 86.6% (23.9%) vs 94.8% (10.6%) for HM. The main complications of PD were perforation and gastroesophageal reflux disease. CONCLUSION: HM is the most effective long-term treatment for patients with achalasia in China. In the future, controlled clinical trials on the treatment of achalasia should focus on comparing laparoscopic myotomy with or without antireflux procedure,including different partial and total fundoplication techniques.展开更多

The main objective of this study was to assess the expression of calcineudn （CAN） and Ca^2＋/calmodutin-dependent protein kinase （CAME） in lipogene- sis in chicken muscle. The chickens were slaughtered and sampled at the ages of 4, 8, and 16 weeks, respectively. IMF content and the expression of CaN subunits and CaMK isoforms were measured in thigh muscle tissue. The results showed that the IMF contents were higher in chickens at the age of 16 weeks compared with those in chickens at the ages of 4 and 8 weeks （P〈0.05）. The expression levels of fatty acid synthase （FAS） and fatty acid translocase CD36 （FAT/CD36） mRNA in 16-week-old chickens were all significantly up-regulated compared with those in 4-week-old chickens （P〈0.05）. The mRNA levels of CaNB and CaMK IV in 16-week-old chickens were significantly lower than those in 4-week-old chickens （P〈0.05）. But the CaMK II mRNA levels in 16-week-old chickens were significantly higher than those in 4-week-old chickens （P〈0.05）. To investigate the roles of CaMK and CaN in adipogenesis, SV cells were incubated in standard adipogenesis medium for 24 h and treated with specific inhibitor of CaMK and CaN. The ex- pressions of CCAAT/enhancer binding protein β（C/EBPJ3）, sterol regulatory element- binding protein 1 （SREBP1） and peroxisome proliferation-activated receptor ）, （PPARy） were dramatically enhanced by CsA and CaN inhibitor （P〈0.05）. KN93, a CaMK Ⅱ inhibitor, dramatically repressed the expression of those lipogenic genes （P〈0.05）. All the results above indicated that CaN and CaMK had different effects on adipogenesis in the muscle of chickens.展开更多

Methods： Case-controlled studies （CCTs） were used to compare the two operative methods in the treatment of femoral neck fractures. Data were retrieved from the Cochrane Library, Pubmed Database, CNKI, Chinese Biomedical Database. Wanfang Data published during the period of January 2005 to December 2014. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical Software Revman S.0 was used for data-analysis. Results： Eight articles were included in the meta-analysis. The results showed that there was statistical significance in the rate of fracture healing [OR = 5.43, 95% CI （2.89, 10.20）, p 〈 0.05], the rate of good function of hip joint [OR=5.12, 95% CI （3.21, 8.17）, p 〈 0.05], the rate of femoral head necrosis [OR = 4.21, 95% CI （2.02, 8.76）, p 〈 0.05], the time of fracture healing [WMD = -46.85, 95% CI （-65.13, -28.56）, p 〈 0.05] between the two groups. Conclusions： For the treatment of femoral neck fractures, the transplantation of quadratus femoris muscle pedicle bone flap combined with hollow compression screw; fixation is superior to the AO hollow compression screw fixation in terms of the rate; of fracture healing, the rate of good function of hip joint, the rate of femoral head： necrosis and the time of fracture healing.展开更多
