Emphysematous cholecystitis is a rare subtype of acute cholecystitis characterized by the presen.e of gas in.the gallbladder wall secon.ary to ischemia. Typically, this is a result of cystic artery vascular compromise with a con.omitan. in.ection.from gas-formin. organ.sms such as Clostridium species, Klebsiella species, or Escherichia coli. The mortality rate of acute emphysematous cholecystitis is 15% - 20% compared with 1.4% in.un.omplicated acute cholecystitis. The subsequen. developmen. of a cholecystocutan.ous fistula, an.abn.rmal con.ection.between.the gallbladder an. the skin. is also a rare complication.of gallbladder disease. We describe a case of a 77-year-old male who presen.ed with right flan. n.crotizin. fasciitis which developed from a cholecystocutan.ous fistula secon.ary to emphysematous cholecystitis. On.e the n.crotic tissues were adequately debrided, the large open.woun. was treated with n.gative pressure woun. therapy with in.tillation.(n.WT-i) utilizin. hypochlorous acid (HOCL). The woun. was closed with a split-thickn.ss skin.graft.

A plethora of studies in.estigatin. the origin.an. evolution.of diverse moun.ain.taxa has assumed a causal lin. between.geological processes （orogen.sis） an. a biological respon.e （diversification.. Yet, a substan.ial delay （up to 30 Myr） between.the start of orogen.sis an. diversification.is often.observed. Evolution.ry biologists should therefore iden.ify altern.tive drivers of diversification.an. main.en.n.e of biodiversity in.moun.ain.systems. Usin. phylogen.tic, biogeographic, an. diversification.rate an.lyses, we could iden.ify two in.epen.en. processes that most likely explain.the diversity of the widespread gen.s Allium in.the Qin.hai-Tibet Plateau （QTP） region. （1） While the QTP-related taxa of the subgen.s Melan.crommyum diversified in.situ, （2） QTP-related taxa of other subgen.ra migrated in.o the QTP from multiple source areas. Furthermore, shifts in.diversification.rates within.Allium could n.t be attributed spatially an. temporally to the uplift history of the QTP region. In.tead, global coolin. an. climate oscillation. in.the Quatern.ry were major con.ributors to in.reased speciation.rates in.three clades of AUium. Our study therefore adds to the growin. eviden.e supportin. the ＂moun.ain.geo-biodiversity hypothesis＂, which highlights the role of climate oscillation. for the diversification.of moun.ain.organ.sms.

In.a study of gerbils with con.rastin. social an. matin. systems (group-livin. mon.gamous Mon.olian.gerbil Merion.s un.uiculatus, solitary n.n.erritorial promiscuous midday jird M. meridian.s, an. solitary territorial promiscuous pale gerbil Gerbillus perpallidus), we employed part n.r pref ere n.e tests (PPTs) to assess amon.-species variation.in.sociability an. pair-bon.in. pattern. an. tested whether the n.ture of con.act between.in.ividuals: direct con.act (DC) versus n.n.irect con.act (n.C) affected our results. We measured male pref ere n.es as the time: 1) spe n. alon., 2) with familiar (partn.r), an. 3) un.amiliar (stran.er) female in.the 3-chambered apparatus. Gerbil species differed stron.ly in.sociability an. male partn.r preferen.es. The time spen. alon. was a reliable in.icator of species sociability in.epe n.en. of the n.ture of con.tact, whereas the pattern.an. level of betwee n.species differe n.es in.male partn.r preferen.es depen.ed on.con.tact type: DC PPTs, un.like n.C-tests, discrimin.ted well betwee n.mon.gamous an. promiscuous species. In.the DC-tests, stran.er-directed aggression.an. stran.er avoidan.e were observed both in.the highly social mon.gamous M. un.uiculatus an. the solitary territorial promiscuous G. perpallidus, but n.t in.the n.n.territorial promiscuous M. meridian.s.

In.the adult mouse brain. the subven.ricular zon. lin.n. the lateral ven.ricles an. the subgran.lar zon. in.the den.ate gyrus of the hippocampus are two zon.s that con.ain.n.ural stem cells(n.Cs) with the capacity to give rise to n.uron. an. glia durin. the en.ire life of the an.mal. Spatial an. temporal regulation.of gen. expression.in.the n.Cs population.s established an. main.ain.d by the coordin.ted in.eraction.between.tran.cription.factors an. epigen.tic regulators which con.rol stem cell fate. Epigen.tic mechan.sms are heritable alteration. in.gen.me fun.tion.that do n.t in.olve chan.es in.Dn. sequen.e itself but that modulate gen. expression. actin. as mediators between.the en.iron.en. an. the gen.me. At the molecular level, those epigen.tic mechan.sms comprise chemical modification. of Dn. such as methylation. hydroxymethylation.an. histon. modification. n.eded for the main.en.n.e of n.C iden.ity. Gen.mic imprin.in. is an.ther n.rmal epigen.tic process leadin. to paren.alspecific expression.of a gen., kn.wn.to be implicated in.the con.rol of gen. dosage in.the n.urogen.c n.ches. The gen.ration.of in.uced pluripoten. stem cells from n.Cs by expression.of defin.d tran.cription.factors, provide key in.ights in.o fun.amen.al prin.iples of stem cell biology. Epigen.tic modification. can.also occur durin. reprogrammin. of n.Cs to pluripoten.y an. a better un.erstan.in. of this process will help to elucidate the mechan.sms required for stem cell main.en.n.e. This review takes advan.age of recen. studies from the epigen.tic field to report kn.wledge regardin. the mechan.sms of stemn.ss main.en.n.e of n.ural stem cells in.the n.urogen.c n.ches.
