Naphthenic acids.are a complex clas. of thous.nds.of naturally occurring aliphatic and alicyclic carboxylic acids.found in oil s.nds.bitumen and in the was.ewater generated from bitumen proces.ing. Dozens.of analytical methods.have been developed for the s.miquantification of total naphthenic acids.in water s.mples. However, different methods.can give different res.lts. prompting inves.igation into the comparability of the many methods. A review of important methodological features.for analyzing total naphthenic acids.is.pres.nted and informs.the des.gn of future s.andard methods.for the s.mi- quantification of total naphthenic acids.us.ng mas. s.ectrometry. The des.gn cons.derations.pres.nted are a s.nthes.s.of dis.us.ions.from an Environment and Climate Change Canada （ECCC） led tas.force of 10 laboratory experts.from government, indus.ry and academia during April 2016 and s.bs.quent dis.us.ions.between Univers.ty of Britis. Columbia and ECCC repres.ntatives. Matters.cons.dered are： extraction method, s.lvent, pH, and temperature; analys.s.ins.rumentation and res.lution; choice of calibration s.andards. us. of s.rrogate and internal s.andards. and us. of online or offline s.paration prior to analys.s. The des.gn cons.derations.are amenable to both time-of-flight and Orbitrap mas. s.ectrometers.

Vas.ular injury or interruption may play a role in vertebrate limb teratogenes.s. s.nce 5fluoro- 2'- deoxyuridine (FdU) can caus. vas.ular injury in the murine limb and s.ull prior to the appearance of s.eletal malformations.in thes. s.ructures. we s.udied the effects.of this.chemical on s.eletal development in the chick embryo and noted any vas.ular injury. The yolk s.cs.of day three ehick embryos.(Hamburger and Hamilton s.ates.17-19) were injected with s.lutions.of vary concentrations.of FdU in s.line. The embryos.developed until the 10th day of incubation when they were fixed for s.udy. Uninjected, s.line injected, and s.am injected control embryo were s.milarly fixed. Upon gros. ins.ection, frequent diffus. and s.ccular hernatomas. as.well as.fluid-filled blis.ers. were noted in the limbs.of embryos.treated with FdU.

Bone–cartilage cros.talk:a convers.tion for unders.anding os.eoarthritis

引用

Bone Res.arch 2016年第3期4卷 121-132页

作者： david M Findlay Julia s.Kuliwaba Dis.ipline of Orthopaedics.and Trauma The University of Adelaide

Although cartilage degradation is.the characteris.ic feature of os.eoarthritis.（OA）, it is.now recognized that the whole joint is.involved in the progres.ion of OA. In particular, the interaction （cros.talk） between cartilage and s.bchondral bone is.thought to be a central feature of this.proces.. The interface between articular cartilage and bone of articulating long bones.is.a unique zone, which compris.s.articular cartilage, below which is.the calcified cartilage s.tting on and intercalated into the s.bchondral bone plate. Below the s.bchondral plate is.the trabecular bone at the end of the res.ective long bones. In OA, there are well- char des.ribed *** des.ructive tges.in the ~cular cartilage, which parallel characteris.ic changes.in the underlying hone, This.review examines.the evidence that biochemical and biomechanical s.gnaling between thes. tis.ue compartments.is.important in OA dis.as. progres.ion and as.s.whether s.ch s.gnaling might provide pos.ibilities.for therapeutic intervention to halt or s.ow dis.as. development.

Background: Over the pas. decade, there has.been recognition of the importance of the human microbiome. Beyond improved microbial cataloguing through high- throughput genetic s.quencing, we have learned that human beings.are s.perorganis.s.integrating the identity, function and immunity of res.dent bacterial, while prepared throughout own innate and adaptive immune s.s.ems. to deal with invading organis.s. Hypothes.s. In keeping with the dynamic relation of infection, immunity and inflammation contained in I-Cubed, illnes. aris.s.when protective immunity becomes.the s.urce of autoimmunity, conditioned by environmental and genetic factors. Res.lts. This.paradigm explains.the etiopathogenes.s.of divers. medical (type 1 diabetes. s.ondyloarthropathy), neurologic (Lyme neuroborrelios.s., and neurops.chiatric dis.rders.(PANDAs. and autis. s.ectrum dis.rders.. Conclus.on: s.cces.ful treatments.employing immune-modulatory therapy may be employed. Public health officials.will be called upon to guide the public’s.unders.anding and mitigate the ris. of dis.rders.that res.lt from the interplay of the human microbiome and I-Cubed.

Vaccination programs.need to be evaluated as.regards.their health and economic population benefit among indigenous.at ris. populations.taking into account emerging pathologies.defined by the s.dden appearance of a pathogen in nature or in a region of the world.
