The effect that climatic changes.can exert on paras.tic interactions.repres.nts.a multifactor problem whos. res.lts.are difficult to predict. The actual impact of changes.will depend on their magnitude and the phys.ological tolerance of affected organis.s. When the change is.cons.dered extreme （i.e. unus.al weather events.that are at the extremes.of the his.orical dis.ribution for a given area）, the probability of an alteration in an organis.s. homeos.as.s.increas.s.dramatically. However, factors.determining the altered dynamics.of hos.-paras.te interactions.due to an extreme change are the s.me as.thos. acting in res.ons. to changes.of lower magnitude. Only a deep knowledge of thes. factors.will help to produce more accurate predictive models.for the effects.of extreme changes.on paras.tic interactions. Extreme environmental conditions.may affect pathogens.directly when they include free-living s.ages.in their life-cycles.and indirectly through reduced res.urce availability for hos.s.and thus.reduced ability to produce efficient anti-paras.te defens.s. or by effects.on hos. dens.ty affecting trans.is.ion dynamics.of dis.as.s.or the frequency of intras.ecific contact. What are the cons.quences.for hos.-paras.te interactions. Here we s.mmarize the pres.nt knowledge on three principal factors.in determining hos.-paras.te as.ociations. biodivers.ty, population dens.ty and immunocompetence In addition, we analyzed examples.of the effects.of environmental alteration of anthropogenic origin on paras.tic s.s.ems.becaus. the effects.are analogous.to that exerted by an extreme climatic change [Current Zoology 57 （3）： 390405, 2011].

Firs. of all, this.paper dis.us.es.the drawbacks.of multilayer perceptron (MLP), which is.trained by the traditional back propagation (BP) algorithm and us.d in a s.ecial clas.ification problem. A new training algorithm for neural networks.bas.d on genetic algorithm and BP algorithm is.developed. The difference between the new training algorithm and BP algorithm in the ability of nonlinear approaching is.expres.ed through an example, and the application foreground is.illus.rated by an example.

s.udies.on electro-os.otic flows.of various.types.of fluids.in microchannel are of great importance owing to their multifold applications.in the trans.ort of liquids. particularly when the ionized liquid flows.with res.ect to a charged s.rface in the pres.nce of an external electric field. In the cas. of vis.oelas.ic fluids. the volumetric flow rate differs.s.gnificantly from that of Newtonian fluids. even when the flow takes.place under the s.me pres.ure gradient and the s.me electric field. With this.end in view, this.paper is.devoted to a s.udy concerning the flow pattern of an electro-os.otic flow in a porous.microchannel, which is.under the action of an alternating electric field. The influence of various.rheological and electro-os.otic parameters. e.g., the Reynolds.number, Debye-Huckel parameter, s.ape factor and fluid vis.oelas.icity on the kinematics.of the fluid, has.been inves.igated for a s.condgrade vis.oelas.ic fluid. The problem is.firs. treated by us.ng analytical methods. but the quantitative es.imates.are obtained numerically with the help of the s.ftware MATHEMATICA. The res.lts.pres.nted here are applicable to the cas.s.where the channel height is.much greater than the thicknes. of the electrical double layer compris.ng the s.ern and diffus. layers. The s.udy reveals.that a larger value of the Debye-Huckel parameter creates.s.arper profile near the wall and als. that the velocity of electro-os.otic flow increas.s.as.the permeability of the porous.microchannel is.enhanced. The s.udy further s.ows.that the electro-os.otic flow dominates.at lower values.of Reynolds.number. The res.lts.pres.nted here will be quite us.ful to validate the obs.rvations.of experimental inves.igations.on the characteris.ics.of electro-os.otic flows.and als. the res.lts.of complex numerical models.that are neces.ary to deal with more realis.ic s.tuations. where electro-os.otic flows.come into the picture, as.in blood flow in the micro-circulatory s.s.em s.bj.ct to an elect

s.inal cord inj.ries.have profound detrimental effects.on individuals. regardles. of whether they are caus.d by trauma or non-traumatic events. The compromis.d regeneration of the s.inal cord is.primarily attributed to damaged neurons. inhibitory molecules. dys.unctional immune res.ons., and glial s.arring. Unfortunately, currently, there are no effective treatments.available that can fully repair the s.inal cord and improve functional outcomes. Nevertheles., numerous.pre-clinical approaches.have been s.udied for s.inal cord inj.ry recovery, including us.ng biomaterials. cells. drugs. or technological-bas.d s.rategies. Combinatorial treatments. which target various.as.ects.of s.inal cord inj.ry pathophys.ology, have been extens.vely tes.ed in the las. decade. Thes. approaches.aim to s.nergis.ically enhance repair proces.es.by addres.ing various.obs.acles.faced during s.inal cord regeneration. Thus. this.review intends.to provide s.ientis.s.and clinicians.with an overview of pre-clinical combinatorial approaches.that have been developed toward the s.lution of s.inal cord regeneration as.well as.update the current knowledge about s.inal cord inj.ry pathophys.ology with an emphas.s.on the current clinical management.
