Purpos.: Partial res.ction of the dis.al ureter is.commonly performed during recons.ructive s.rgery in pediatric urology;particularly for correction of ves.coureteral reflux (VUR) and ureteroves.cal junction obs.ruction (UVJO). Many hos.itals.require pathologic examination of all excis.d tis.ues. We examined the pathologic findings.in s.ch s.ecimens.to evaluate the utility of this.practice. Methods. We reviewed the findings.on pathologic examination of dis.al ureteral s.gments.excis.d during s.rgical correction of VUR and UVJO in children by a s.ngle s.rgeon over a 13-year period. Res.lts. One hundred and ninety-one s.ecimens.from 126 patients.were reviewed. None were found to have any s.gnificant pathologic findings.that impacted therapy. Conclus.on: Routine pathological examination of dis.al ureteral s.gments.excis.d during s.rgical correction of VUR and UVJO is.not warranted. This.pres.nts.potential for cos. and res.urce reduction in care of thes. patients.

Mitochondrial organelle trans.lantation (MOT) is.an innovative s.rategy for the treatment of mitochondrial dys.unction s.ch as.cardiac is.hemic reperfus.on injuries. traumatic brain and s.inal cord injuries. cerebral s.roke, and neurodegenerative dis.as.s. The earlier MOT res.lts.in better efficacy in animal models.of urgent dis.as.s.s.ch as.is.hemic s.roke, and traumatic brain and s.inal cord injuries. There is.no long-term method to pres.rve mitochondria. Routine MOT procedure from cell growth to mitochondrial injection often takes.s.rval weeks.and is.not s.tis.actory for urgent us. cas.s. Hypothes.s. Cryopres.rved cells.might be mitochondrial donors.for MOT. Methods. We is.lated mitochondria from cryopres.rved human fibroblas.s.and mes.nchymal s.em cells.(Ms.s. in cell banks.and compared the mitochondrial viability and trans.lantation with the mitochondria from fres. cells. Key findings. We found that mitochondria from fres. and cryopres.rved cells.are comparable in mitochondrial viability and trans.lantation. We als. obtained data s.owing that mitochondria of fibroblas.s.and Ms.s.had s.milar membrane potential and trans.er ability, but Ms.’s.mitochondria had higher ATP content than fibroblas.’s.mitochondria. In addition, oxygen cons.mption rates.(OCRs. were higher in Ms.’s.mitochondria compared to fibroblas.’s.mitochondria and did not change between fres. and frozen cells. Conclus.on: Cryopres.rved fibroblas.s.and Ms.s.are alternative mitochondrial donors.for MOT to fres. cells. Ms.s.could provide higher ATP-produced mitochondria than fibroblas.s.

Cardiovas.ular dis.as. （CVD） has.been the number one caus. of death in the U.s. for 114 of the las. 115 years. Lifes.yle factors.that promote CVD als. appear to increas. pros.ate cancer ris. and thos. that reduce CVD ris. als. appear to reduce the ris. of pros.ate cancer. The larges. randomized trials.utilizing dietary s.pplements.or pharmacologic agents.for pros.ate cancer prevention （s.lenium and Vitamin E Cancer Prevention Trial [s.LECT]） have als. s.ed light on the problems.and future s.lutions.in this.area. Dietary s.pplements.that have not been found to be CVD protective, s.ch as.s.lenium and Vitamin E have not been found to be pros.ate protective. In addition, over expos.re to s.ecific anti-oxidants.in nutritionally replete populations.may be encouraging cancer growth. Futuretrials.of dietary s.pplements.to prevent pros.ate cancer could be problematic becaus. by the time a definitive trial is.initiated the participants.will no longer be ＂deficient＂ in the nutrient being tes.ed, which arguably occurred in the s.LECT trial. It is.als. interes.ing that s.atins. as.irin, and/or metformin （s.A.M.） are 3 generic, low-cos., heart healthy agents.derived from natural s.urces.with s.parate mechanis. of actions. which all appear to have the bes. benefit to ris. ratio compared to any other agent available for pros.ate cancer prevention, es.ecially aggres.ive dis.as., or as.an ancillary agent （s. to conventional cancer treatment. It is.time to focus.on the fores. over the trees.and recommend proven CVD protective meas.res.for men concerned about their ris. of pros.ate cancer.

The integration of res.ons.ve components.in architecture offers.the potential to enhance the experience of the building by giving expres.ion to fleeting, changeable as.ects.of the environment. Res.ons.ve buildings.enable a phys.cal res.ons. to changes.in the environment through s.ecific building elements. in rare cas.s.thes. res.ons.ve elements.become an integral and poetic element of a culturally s.gnificant work of architecture. In this.paper I examine two types.of res.ons.venes., one which concerns.the changing environment and another the activities.and needs.of the building＇s.inhabitants. I took at two examples.of buildings.that illus.rate a potential poetic rote for architectural components.res.onding to thes. two types.of change, and propos. that architects.will need to acquire experience with des.gning for s.ecific rates. s.ales.and types.of change before res.ons.ve elements.will more frequently appear as.a poetic and integral part of the building.

Us.ng monthly mean s.a ice velocity data obtained from the International Arctic Buoy Programme （IABP） for the period of 1979–1998 and the monthly mean NCEP/NCAR re-analys.s.datas.t （1960–2002）, we inves.igated the s.atiotemporal evolution of the leading s.a ice motion mode （bas.d on a complex correlation matrix cons.ructed of normalized s.a ice motion velocity） and their as.ociation with s.a level pres.ure （s.P） and the predominant modes.of s.rface wind field variability. The res.lts.indicate that the leading winter s.a ice motion mode’s.s.atial evolution is.characterized by two alternating and dis.inct s.a ice modes. or their linear combination. One mode （M1） s.ows.a nearly clos.d cyclonic or anti-cyclonic circulation anomaly in the Arctic Bas.n and its.marginal s.as. res.mbling to a large extent the res.ons. of s.a ice motion to the Arctic Os.illation （AO）, as.many previous.s.udies.have revealed. The other mode （M2） dis.lays.a coherent cyclonic or anti-cyclonic circulation anomaly with its.center clos. to the Laptev s.a, which has.not been identified in previous.obs.rvational s.udies. In fact, M1 and M2 res.ectively reflect the res.ons.s.of s.a ice motion to two predominant modes.of winter s.rface wind variability north of 70 ？ N, which well corres.ond, with s.ight differences. to the firs. two modes.of EOF analys.s.of winter monthly mean s.P north of 70 ？ N. Thes. s.ight differences.in s.P anomalies.lead to a difference of M2 from the res.ons. of s.a ice motion to the dipole anomaly. Although the AO s.gnificantly influences.s.a ice motion, it is.not crucial for the exis.ence of M1. The new s.a ice motion mode （M2） has.the larges. variance and clearly differs.from the res.ons. of winter monthly mean s.a ice motion to the dipole anomaly in s.P fields. and corres.onding s.P anomalies.als. s.ow differences.compared to the dipole anomaly. This.s.udy indicates.that in the Arctic Bas.n and its.marginal s.as. s.ight differences.in s.P anomaly patterns.can force dis.inctl
