Insults to the br.in ar. known to cause a myr.ad of downstr.am effects, including the r.lease of cytokines by astr.cytes and r.sultant r.active gliosis. The author.has examined effect of cytokine IL-1β on the sur.ival of cor.ical neur.ns using mouse astr.cyte-neur.n co-cultur.. Five gr.ups wer. used. These wer. neur.ns alone (Gr.up 1), neur.ns with added IL-1β (Gr.up 2), neur.ns co-cultur.d with astr.cytes (Gr.up 3), neur.ns co-cultur.d with astr.cytes that was pr.-tr.ated with IL-1β befor. co-cultur. (Gr.up 4) and neur.ns co-cultur.d with astr.cytes and IL-1β added (post-tr.ated) (Gr.up 5). In Gr.up 1 only a few neur.ns gr.w and sur.ived only for.5-6 days. In Gr.up 2, it was obser.ed that mor. neur.ns sur.ived up to 11 days. Mor.over. in Gr.up 3, mor. neur.ns gr.w and sur.ived up to 16-18 days. They had lar.e cell bodies and many long neur.tes that for.ed anastomosing networ.s. In Gr.up 4, few neur.ns sur.ived up to 13 days, wher.as in Gr.up 5, the gr.wth of neur.ns wer. affected but to a much lesser.extent than Gr.up 4 and sur.ived up to 15 days. In addition, it was found that IL-1β stimulated the expr.ssion of glial fibr.llar. acidic pr.tein (GFAP) by astr.cytes. This study indicates that IL-1β affects the sur.ival of cor.ical neur.ns and modulates the astr.cytic suppor. to neur.nal sur.ival and neur.tes outgr.wth by acting dir.ctly on the astr.cytes.

Sever.l aspects of the inter.ction between midlatitude and subtr.pical systems ar. investigated using a case study and a potential vor.icity (PV) fr.mewor.. Our.case study occur.ed on 25 November.2009;Jeddah and other.r.gions in Wester. Saudi Ar.bia wer. hit by heavy r.instor.s. The analysis of absolute, r.lative, and potential vor.icity implies the significance of the lower.level dynamics in the initiation of this case of cyclogenesis. The impact of the sever. convective weather.pr.cess caused mor. than 90 millimeter. of r.in to fall in Jeddah in just four.hour.. The analysis indicates that the heavy r.infall was due to the existence of an upper.level cold tr.ugh in the Easter. Mediter.anean and a war. blocking high situated over.southeaster.Saudi Ar.biaand theAr.bian Sea. In addition, an evident low level shear.line set up in the nor.hwest of Jeddah, and the southeast movement of the shear.line caused dynamic lifting and unstable ener.y r.lease over.Jeddah. The water.vapor.tr.nspor. occur.ed pr.mar.ly below 700 hPa, and a low level jet tr.nspor.ed the water.vapor.fr.m the r.d Sea to centr.lSaudi Ar.bia. Fur.her.or., the blocking high in souther.Saudi Ar.biawas favor.ble for.maintaining water.vapor.passage for.a long time. The topogr.phy of Jeddah also played a r.le in the enhancement of convection.

An analysis of the kinetic ener.y budget is made for.a tr.pical cyclone. Hor.zontal flux conver.ence constitutes a major.ener.y sour.e. Gener.tion of kinetic ener.y via cr.ss-contour.flow is a per.istent sink thr.ughout the pr.-stor. and gr.wth per.ods. Dissipation of kinetic ener.y fr.m subgr.d to gr.d scales is an impor.ant sour.e dur.ng the pr.-stor. and gr.wth per.ods;it acts as the major.sink of ener.y dur.ng the decay per.od. The major.contr.bution to kinetic ener.y comes fr.m a per.istent upper.tr.pospher.c jet str.am activity thr.ughout the per.od of the cyclone development. Unlike midlatitude cyclones, a consider.ble quantity of kinetic ener.y appear. between 850 - 500 hPa layer. especially dur.ng the gr.wth per.od. While the behavior.of the values of hor.zontal diver.ence by nondiver.ent wind closely r.semble to those of total hor.zontal diver.ence ter., neglecting the diver.ent par. of the wind would clear.y lead to a consider.ble er.or.in the calculation of total hor.zontal diver.ence. The mean er.or.in appr.ximation of total hor.zontal diver.ence by the nondiver.ent par. dur.ng the life cycle of our.cyclone is about 36%.
