A new record of the capped langur (Trachypithecus pileatus) in China

DEAR EDITOR, The distribution of the capped langur (Trachypithecus pileatus)in China has become controversial since Shortridge's langur (Trachypithecus shortridgei) was upgraded to a full species.The capped langur is considered to be distributed in northeast India,Bangladesh,Bhutan,and northwest Myanmar only (Brandon-Jones et al.,2004;Choudhury,2008,2014;Das et al.,2008;Groves,2001).In our field survey,however,we obtained photos of the capped langur,demonstrating its existence in China. Following the species promotion of Shortridge's langur (Brandon-Jones et al.,2004;Groves,2001) and the delimiting of its distribution range to northwestern Yunnan in China and northeastern Myanmar (Brandon-Jones et al.,2004;Cui et al.,2016;Das et al.,2008;Groves,2001;Htun et al.,2008),with a new record in southeastern Tibet (Wu et al.,2016),the capped langur has been deleted from the checklist of mammals in China (Jiang et al.,2015).Despite this,Dr.George Schaller has suggested that capped langurs might exist in the northeastern section of the Yarlung-Zangbo River (Choudhury,2008).     

Acute paralysis viruses of the honey bee

<正>The alarming decline of honey bee(Apis mellifera)colonies in the last decade drove the attention and research to several pathogens of the honey bee including viruses.Viruses challenge the development of healthy and robust colonies since they manage to prevail in an asymptomatic mode and reemerge in acute infections following external stresses,as well as they are able to infect new healthy colonies(de Miranda J R,et al.,2010a;de Miranda J R,et al.,2010b;Di Prisco G,et al.,2013;Nazzi F,et al.,2012;Yang X L,et al.,2005).     

Genome-Wide Analysis of Gene Expression in Stationary Phase and Genetic Characterization of Stationary-Phase-Dependent Halocin Gene Expression in the Haloarchaeon Haloferax mediterranei

The stationary phase of microbial growth is a very complex state regulated by various environmental and physiological factors.An intensive study of stationary phase could promote a comprehensive understanding of the complete life cycle of microorganisms,and may provide important insights into their adaptation to harsh and nutrient-depleted conditions.Although the underlying mechanisms have been well-studied in bacteria and yeasts (Herman,2002;Navarro Llorens et al.,2010),less is known about this growth phase in archaea yet.The haloarchaeon Haloferax mediterranei has served as a good model for studying haloarchaeal physiology and metabolism for several decades because of its accelerated growth,remarkable metabolic ability and genomic stability (Han et al.,2012).During stationary phase,H.mediterranei can produce halocin H4 (Cheung et al.,1997),synthesize gas vesicles (J(a)ger et al.,2002),secrete extracellular polysaccharide (Antón et al.,1988) and accumulate poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV)(Cai et al.,2012).Due to these specific features,we selected H.mediterranei as a model system to investigate the archaeal gene expression and regulation during the stationary phase.     

Engrafted newborn neurons could functionally integrate into the host neuronal network

The limited capability to regenerate new neurons following injuries of the central neural system (CNS) still remains a major challenge for basic and clinical neuroscience.Neural stem cells (NSCs) could nearly have the potential to differentiate into all kinds of neural cells in vitro.Previous studies verified that exogenous transplanted NSCs are capable of differentiating into neurons and projecting onto the host neurons in the rat brain (Tabar et al.,2005;Dong JR et al.,2012),which could lead to behavioral recovery from neuronal damages such as spinal cord injury (McDonald et al.,1999),Parkinson's disease (Gonzalez et al.,2015;Kim et al.,2002;Lindvall,2001),and stroke (Zhang et al.,2016).

MASTODONT REMAINS FROM THE MIOCENE OF JUNGGAR BASIN IN XINJIANG

<正> The mastodont materials described in the present paper, associated with Amblycastor tunggurensis, Amphicyon sp., Anchitherium cf. aurelianense, Brachypotherium sp., ?Chilotherium sp., Stephanocemas thomsoni, Dicrocerus grangeri, Eotragus sp., Oioceros grangeri and O. noverca, were collected from the Haramagai formation of Junggar Basin in Xinjiang by an IVPP field team in 1982. The geology of the area has already been reported by Tong (1986, 1987). The mastodont fossils found at 5 sites on the north and west banks of the Ulungur river, Junggar Basin are abundant. They comprise 5 species, among which is one new species.The author is greatly indebted to the IVPP field team (Tong, Y., the head of the 1982 Junggar field team) allocating the mastodont materials for me to study.     

Synthetic genomes engineered by SCRaMbLEing

正The ability to design and synthesize the genome of a living organism marks one of the most significant achievements in synthetic biology.The first synthetic genomes were those of bacteria(Gibson et al.,2010;Hutchison et al.,2016),but an international consortium of scientists is now undertaking the ambitious task of designing and synthesizing the entire genome of Saccharomayces cerevisiae,a eukaryotic singlecelled yeast(Dymond et al.,2011;Kannan and Gibson,2017).One feature of the redesigned yeast genome,called     

江豚肝内门静脉系的初步观察

The portal venous system within liver of Neophocaena phocaenoides asiaeorientalis was observed.The portal venous system is similar to other mammals (pig,rabbit,ox,dog,goat,rhesus monkey).The R.sinister of the portal vein gives off the v.dorsalis lobi sin lat.,the v. ventralis lobi sin.lat.,the v.lateralis lobi sin.med.,the v. medialis lobi sin,med.,Rr.lobi caudati and Rr.lobi quadrati;the R.dexter of portal vein gives off the v.lobi dext.med.,the v.lobi dext.lat,and the V.processus caudati.It seems that the portal venous system of aquatic mammals and terrestrial mammals show no obvious difference.

A Robust Noninvasive Approach to Study Gut Microbiota Structure of Amphibian Tadpoles by Feces

The 16S rDNA amplicon high-throughput sequencing technique provides a robust and inexpensive approach to detect the gut microbiota of amphibians. Since different experimental protocols generate technical biases in drawing the gut microbiota profiles, the integrative analysis of gut microbiota produced by different studies must be performed with circumspection. In this study, we compared the efficacy of two DNA extraction methods(i.e., a phenol-chloroform method and TIANamp Stool DNA Kit) in describing intestinal and fecal bacterial communities of transplanted Asiatic toad(Bufo gargarizans) tadpoles. In terms of the DNA extraction quality(i.e., DNA purity and yield rate) and the consistency in between fecal and intestinal microbiota structures(i.e., α and β diversity indices), the phenol-chloroform method was more robust than this commercial stool kit in profiling gut microbiota of tadpoles with feces.
