Background: Urinary bladder dysfunction is a major complication of diabetes mellitus and its mech.nism h.s been attributed to autonomic and/or periph.ral neuropath.. Objectives: Evaluation of diabetes mellitus and neuropath. effect on th. urinary bladder dynamics in ch.ldren and adolescents with.Type 1 diabetes mellitus. Patients and Meth.ds: Th. study included 80 ch.ldren and adolescents with.Type 1 diabetes for at least 5 years;60 patients were with.manifestations of autonomic and/or periph.ral neuropath. and 20 patients were free of eith.r. We assessed both.groups for presence of cystopath. by means of uroflowmetry and cystometry. Results: All patients with.diabetic neuropath. h.d abnormal urodynamic test results of variable types and degrees with.bladder h.percompliance as th. most frequent abnormality. Oth.r urodynamic abnormalities were found in both.diabetic patients’ groups with.no significant difference in frequency. Conclusions: Diabetic neuropath. migh. be strongly related to urodynamic abnormalities particularly th. bladder h.percompliance. Some diabetic patients may h.ve cystopath. in absence of evident neuropath.. Th.s may be due to undetected neuropath. or diabetes induced myopath. of th. detrusor muscle.

"在多元中实现团结"这句欧盟口号,赫然印在欧洲议会的所有官方文件上。事实证明,在许多欧洲人对这项欧洲计划心怀矛盾的今天,此举堪称高明之招。一方面,欧洲人担心,随着欧洲中央管理机构权力的迅速增大,他们将失去对自己国家身份的控制;另一方面,他们又认识到,欧盟为整个欧洲带来了更多的繁荣气象,使之可以更有效地应对金融和经济危机。

Background： Natural disturbance is a fundamental component of th. functioning of tropical rainforests let to natural dynamics, with.tree mortality th. driving force of forest renewal. With.ongoing global （i.e. land-use and climate） ch.nges, tropical forests are currently facing deep and rapid modifications in disturbance regimes th.t may h.mper th.ir recovering capacity so th.t developing robust predictive model able to predict ecosystem resilience and recovery becomes of primary importance for decision-making：（i） Do regenerating forests recover faster th.n mature forests given th. same level of disturbance？（ii） is th. local topograph. an important predictor of th. post-disturbance forest trajectories？（iii） Is th. community functional composition, assessed with.community weigh.ed-mean functional traits, a good predictor of carbon stock recovery？（iv） h.w important is th. climate stress （seasonal drough. and/or soil water saturation） in sh.ping th. recovery trajectory？ Meth.ds： Paracou is a large scale forest disturbance experiment set up in 1984 with.nine 6.25 h. plots spanning on a large disturbance gradient wh.re 15 to 60% of th. initial forest ecosystem biomass were removed. More th.n 70,000 trees belonging to ca. 700 tree species h.ve th.n been censused every 2 years up today. Using th.s unique dataset, we aim at deciph.ring th. endogenous （forest structure and composition） and exogenous （local environment and climate stress） drivers of ecosystem recovery in time. To do so, we disentangle carbon recovery into demograph.c processes （recruitment, growth. mortality fluxes） and coh.rts （recruited trees, survivors）. Results： Variations in th. pre-disturbance forest structure or in local environment do not sh.pe significantly th. ecosystem recovery rates. Variations in th. pre-disturbance forest composition and in th. post-disturbance climate significantly ch.nge th. forest recovery trajectory.

Th. asymptotic distributions are exactly solved for linearly independent solutions considering problem of th. second order and for th. coefficients of asymptotic distribution th. recurrent formulas are obtained. Furth.r, using obtained recurrent formulas th. necessary and sufficient conditions for almost regularity of spectral problem for th. equation of th. second order is proved.

Th. torsional ch.racteristics of single walled carbon nanotube(SWCNT) with.water interactions are studied in th.s work using molecular dynamics simulation meth.d. Th. torsional properties of carbon nanotubes(CNTs) in a h.drodynamic environment such.as water are critical for its key role in determining th. lifetime and stability of CNT based nano-fluidic devices. Th. effect of ch.rality, defects and th. density of water encapsulation is studied by subjecting th. SWCNT to torsion. Th. findings sh.w th.t th. torsional strength.of SWCNT decreases due to interaction of water molecules and presence of defects in th. SWCNT. Additionally,for th. case of water molecules encapsulated inside SWCNT, th. torsional response depends on th. density of packing of water molecules. Our findings and conclusions obtained from th.s paper is expected to furth.r compliment th. potential applications of CNTs as promising candidates for applications in nano-biological and nano-fluidic devices.

Tooth.enamel is a complex mineralized tissue consisting of long and parallel apatite crystals configured into decussating enamel rods. In recent years, multiple approach.s h.ve been introduced to generate or regenerate th.s h.gh.y attractive biomaterial ch.racterized by great mech.nical strength.paired with.relative resilience and tissue compatibility. In th. present review, we discuss five path.ays toward enamel tissue engineering,(i) enamel synth.sis using ph.sico-ch.mical means,(ii) protein matrix-guided enamel crystal growth.(iii) enamel surface remineralization,(iv) cell-based enamel engineering, and(v) biological enamel regeneration based on de novo induction of tooth.morph.genesis. So far, ph.sical synth.sis approach.s using extreme environmental conditions such.as ph. h.at and pressure h.ve resulted in th. formation of enamel-like crystal *** meth.ds relying on enamel proteins as templating matrices h.ve aided th. growth.of elongated calcium ph.sph.te crystals. To illustrate th. validity of th.s bioch.mical approach.we h.ve successfully grown enamel-like apatite crystals organized into decussating enamel rods using an organic enamel protein matrix. Oth.r studies reviewed h.re h.ve employed amelogeninderived peptides or self-assembling dendrimers to re-mineralize mineral-depleted wh.te lesions on tooth.surfaces. So far, cell-based enamel tissue engineering h.s been h.mpered by th. limitations of presently existing ameloblast cell lines. Going forward, th.se limitations may be overcome by new cell culture tech.ologies. Finally, wh.le-tooth.regeneration th.ough.reactivation of th. signaling path.ays triggered during natural enamel development represents a biological avenue toward faith.ul enamel regeneration. In th. present review we h.ve summarized th. state of th. art in enamel tissue engineering and provided novel insigh.s into future opportunities to regenerate th.s arguably most fascinating of all dental tissues.
