1The key theorem and the bounds on the rate of uniform convergence of learning theory on Sugeno measure space显示文摘Some properties of Sugeno measure are further discussed, which is a kind of typical nonadditive measure. The definitions and properties of gλ random variable and its distribution function, expected value, and variance are then presented. Markov ine- quality, Chebyshev’s inequality and the Khinchine’s Law of Large Numbers on Sugeno measure space are also proven. Furthermore, the concepts of empirical risk functional, expected risk functional and the strict consistency of ERM principle on Sugeno measure space are proposed. According to these properties and concepts, the key theorem of learning theory, the bounds on the rate of convergence of learning process and the rela- tions between these bounds and capacity of the set of functions on Sugeno measure space are given.HA Minghu LI Yan LI Jia TIAN Dazeng 2006Science in China(Series F)2006,49,3:16

3Mechanistic links between gut microbial community dynamics, microbial functions and metabolic health显示文摘Gut microbes comprise a high density, biologically active community that lies at the interface of an animal with its nutritional environment. Consequently their activity profoundly influences many aspects of the physiology and metabolism of the host animal. A range of microbial structural components and metabolites directly interact with host intestinal cells and tissues to influence nutrient uptake and epithelial health. Endocrine, neuronal and lymphoid cells in the gut also integrate signals from these microbial factors to influence systemic responses. Dysregulation of these host-microbe interactions is now recognised as a major risk factor in the development of metabolic dysfunction. This is a two-way process and understanding the factors that tip host-microbiome homeostasis over to dysbiosis requires greater appreciation of the host feedbacks that contribute to regulation of microbial community composition. To date, numerous studies have employed taxonomic profiling approaches to explore the links between microbial composition and host outcomes(especially obesity and its comorbidities), but inconsistent host-microbe associations have been reported. Available data indicates multiple factors have contributed to discrepancies between studies. These include the high level of functional redundancy in host-microbiome interactions combined with individual variation in microbiome composition; differences in study design, diet composition and host system between studies; and inherent limitations to the resolution of r RNA-based community profiling. Accounting for these factors allows for recognition of the common microbial and host factors driving community composition and development of dysbiosis on high fat diets. New therapeutic intervention options are now emerging.Connie WY Ha Yan Y Lam Andrew J Holmes 2014World Journal of Gastroenterology2014,20,44:4
4Ecological niches and blood sources of sand fly in an endemic focus of visceral leishmaniasis in Jiuzhaigou,Sichuan,China显示文摘Background:Sand fly Phlebotomus chinensis is a principle vector for the visceral leishmaniasis(VL)in China with a wide geographic distribution.Jiuzhaigou,Sichuan is a mountain type endemic area of VL in China.Long term effective control efforts in the region have successfully reduced VL transmission.To assess the current status of the sand flies and their ecological aspects in the region,a survey was conducted in the summer of 2014 and 2015.Methods:Sand fly specimens were collected by light traps in a village and blood sources were identified by PCR and sequencing of the mitochondrial cytochrome b gene.Results:In a rock cave,65.2%–79.8%of collected sand flies were male.On a rabbit farm,92.9%–98.8%of specimens were female.In pig pens,61.1%of specimens were female.Some females had visible blood residues.The feeding rate was 49.4%from the pig pens,12.3%from the cave,and only 1.7%from the rabbit farm.Pig,rabbit,chicken,dog,and human blood were detected in the fed specimens.Swine blood,present in all tested samples,was a preferred blood source,while chicken and dog blood were present in a third of the samples.Conclusions:In Jiuzhaigou County,Sichuan Province of China,the considerable sandfly density and the peridomestic feeding behavior all increases the risk of VL transmission,and insecticide spraying in animal sheds could be exploited to reduce sand fly populations in human surroundings.Huiying Chen Kaili Li Hua Shi Yong Zhang Yu Ha Yan Wang Jinjin Jiang Yubin Wang Zhenzhou Yang Jiannong Xu Yajun Ma 2016Infectious Diseases of Poverty2016,5,1:3

12Ethanol extract of Oenanthe javanica increases cell proliferation and neuroblast differentiation in the adolescent rat dentate gyrus显示文摘Oenanthe javanica is an aquatic perennial herb that belongs to the Oenanthe genus in Apiaceae family, and it displays well-known medicinal properties such as protective effects against glutamate-induced neurotoxicity. However, few studies regarding effects of Oenanthe javanica on neurogenesis in the brain have been reported. In this study, we examined the effects of a normal diet and a diet containing ethanol extract of Oenanthe javanica on cell proliferation and neuroblast differentiation in the subgranular zone of the hippocampal dentate gyrus of adolescent rats using Ki-67(an endogenous marker for cell proliferation) and doublecortin(a marker for neuroblast). Our results showed that Oenanthe javanica extract significantly increased the number of Ki-67-immunoreactive cells and doublecortin-immunoreactive neuroblasts in the subgranular zone of the dentate gyrus in the adolescent rats. In addition, the immunoreactivity of brain-derived neurotrophic factor was significantly increased in the dentate gyrus of the Oenanthe javanica extract-treated group compared with the control group. However, we did not find that vascular endothelial growth factor expression was increased in the Oenanthe javanica extract-treated group compared with the control group. These results indicate that Oenanthe javanica extract improves cell proliferation and neuroblast differentiation by increasing brain-derived neurotrophic factor immunoreactivity in the rat dentate gyrus.Bai Hui Chen Joon Ha Park Jeong Hwi Cho In Hye Kim Bich Na Shin Ji Hyeon Ahn Seok Joon Hwang Bing Chun Yan Hyun Jin Tae Jae Chul Lee Eun Joo Bae Yun Lyul Lee Jong Dai Kim Moo-Ho Won Il Jun Kang 2015Neural Regeneration Research2015,10,2:1

15Neuroprotective effects of ischemic preconditioning on hippocampal CA1 pyramidal neurons through maintaining calbindin D28k immunoreactivity following subsequent transient cerebral ischemia显示文摘Ischemic preconditioning elicited by a non-fatal brief occlusion of blood flow has been applied for an experimental therapeutic strategy against a subsequent fatal ischemic insult. In this study, we investigated the neuroprotective effects of ischemic preconditioning(2-minute transient cerebral ischemia) on calbindin D28k immunoreactivity in the gerbil hippocampal CA1 area following a subsequent fatal transient ischemic insult(5-minute transient cerebral ischemia). A large number of pyramidal neurons in the hippocampal CA1 area died 4 days after 5-minute transient cerebral ischemia. Ischemic preconditioning reduced the death of pyramidal neurons in the hippocampal CA1 area. Calbindin D28k immunoreactivity was greatly attenuated at 2 days after 5-minute transient cerebral ischemia and it was hardly detected at 5 days post-ischemia. Ischemic preconditioning maintained calbindin D28 k immunoreactivity after transient cerebral ischemia. These findings suggest that ischemic preconditioning can attenuate transient cerebral ischemia-caused damage to the pyramidal neurons in the hippocampal CA1 area through maintaining calbindin D28k immunoreactivity.In Hye Kim Yong Hwan Jeon Tae-Kyeong Lee Jeong Hwi Cho Jae-Chul Lee Joon Ha Park Ji Hyeon Ahn Bich-Na Shin Yang Hee Kim Seongkweon Hong Bing Chun Yan Moo-Ho Won Yun Lyul Lee 2017Neural Regeneration Research2017,12,6:1
