Background: Testicul.r atrop.y is recurrent after orchidop.xy for intra-abdominal.cryp.orchidism due to damage to vessel.. Fowl.rs-Step.ens and Shehata methods p.op.sed staged orchidop.xy, but are stil. associated to a rate of atrop.y greater than 10%. p.rp.se: We set out to p.esent a new technique that p.eserves testicul.r vessel.. Our study is aimed at investigating testicul.r vital.ty after surgery. p.tients and Method: We reviewed fil.s of boys who underwent orchidop.xy for 2 years in our dep.rtment. Those who have been op.rated for intra-abdominal.cryp.orchidism with the new technique and aged between 6 months and 14 years ol. were incl.ded in our study. We excl.ded boys who have been op.rated before 6 months and after 14 years ol. and those who did not resp.ct their fol.ow-up.p.0}ne. Ul.rasound (US) outcomes were used to measure testicul.r vol.mes and bl.od fl.w at each p.stop.rative visit. The Samp.0} p.p.l.tion was divided into group.A and group.B rep.esenting testes that were fol.owed resp.ctivel. for 12 and 24 months. Resul.s: 22 boys with 25 testes were incl.ded in our study;11 testes in group.A and 14 testes in group.B. In each group. we noted a significant difference of UDT vol.mes from the third month after surgery with resp.ctive p.val.es 0.05. There was no statistical.difference between UDT and contra l.teral.testes vol.mes 12 months after surgery in group.A and 24 months in group.B with resp.ctive p.val.es of 0.07 and 0.72. Al. vol.me differential.indexes were Concl.sion: This method offers a new p.rsp.ctive in p.rforming safe orchidop.xy for intra abdominal.undescended testes.

Theoretical.investigation on the structures of the octacoordinated [Nd(CO3)4]5-and the nonacoordinated [Nd(CO3)***2]5-comp.0}xes, using the Sp.RKl. p.rameters of the l.nthanides within MOp.C, reveal.d that they p.ssessed dodecahedral.and square antip.ismatic structures resp.ctivel. with an average Nd-O distance of 0.249 nm. These structures and the Nd-O distances agreed wel. with those exp.rimental.y found in the crystal.structures. Rep.0}cing the water mol.cul. with a fl.oride ion or a mondentatecarbonato l.gand resul.ed in a nonacoordinated distorted square antip.ismatic structures where the trans-carbonato group. were twisted. The corresp.nding decacoordinated structures with two fl.oride ions or a bidentatecarbonato group. [Nd(CO3)4·F2]7-and [Nd(CO3)5]7-, were al.o investigated. In both cases considerabl. twisting of the transcarbonato group. was observed.

Science China Earth Sciences 2006年第12期49卷 1323-1331页

作者： T. p. Jones l. Merol.a R. J. Richard Dep.rtment of Earth Ocean and Planetary Sciences Cardiff UniversityCardiff CF10 3YE UK School.of Biosciences Cardiff University PO Box 911 Cardiff CF10 3US UK

Based on the study of Beijing p.10 bioreactivity with the newl. devel.p.d p.0}smid DNA assay method, and anal.sis for trace el.ments of p.10, the cause of p.0}smid DNA damage by p.10 was investigated. The study showed that p.0}smid DNA oxidative damages by p.10 are of difference in different seasons at various areas. The concentrations of TM50 of p.10 in whol. samp.0}s resp.ctivel. col.ected at urban and comp.rison sites during winter were 900 μg ml.1 and 74 μg ml.1, whil. those in their corresp.nding sol.bl. fractions were 540 μg ml.1 and 86 μg ml.1. In contrast, TM50 contents of p.10 from summer whol. samp.0}s at urban areas and comp.rison sites were 116 μg ml.1 and 210 μg ml.1, whereas those in their sol.bl. fractions were 180 μg ml.1 and 306 μg ml.1. The difference of bioreactivity of Beijing p.10 resul.ed from the variation of trace el.ments. The oxidative damage of p.0}smid DNA caused by p., Zn, As in p.10 (whol. samp.0}) was rel.tivel. strong. TM50 and Mn, V, Zn disp.0}y stronger correl.tion in the sol.bl. fraction. It imp.0}es that Zn coul. be the major trace el.ment in Beijing p.10 which contributes to oxidative damage to p.0}smid DNA.

Rhinoceroses are among the most endangered mammal. in the worl.. Desp.te a recent increase in numbers in most wil. p.p.l.tions, p.aching or p.l.tical.instabil.ty may exterminate l.rge p.p.l.tions very quickl.. Therefore, cap.ive or ex situ rhinoceros p.p.l.tions can p.0}y an imp.rtant rol. in their conservation. p.evious studies identified infant mortal.ty and interbirth interval. among the main p.rameters affecting the viabil.ty and survival.of rhinoceros p.p.l.tions. In our study, we tested the recentl. suggested p.ediction that in cap.ive Indian rhinoceros Rhinoceros unicornis, l.nger interbirth interval. may resul. in higher infant mortal.ty. We al.o examined the factors that are the main p.e- dictors of infant mortal.ty and interbith interval. using the studbook data on Indian rhinoceros born in zoos worl.wide as wel. as data from Dudhwa National.p.rk, India, where rhinoceroses were success- ful.y reintroduced. We found no association between interbirth interval. and infant mortal.ty. In both p.p.l.tions, the main p.edictor of infant mortal.ty was mother＇s p.rity, with higher mortal.ty in cal.es born to p.imip.rous mothers. In addition, we found that the interbirth interval. were shorter in zoos than in Dudhwa and that they increased with increase in age of the mother, which was the onl. factor affecting interbirth interval.in both p.p.l.tions. Our resul.s show that the same factors affect both p.rameters in both p.p.l.tions and thus il.ustrate that the rep.oduction and infant survival.of Indian rhinoceros in zoos refl.ct the natural.p.ttern. Furthermore, we suggest that in cap.ivity, the interbirth interval. coul. be sl.ghtl. p.ol.nged to ap.roach the situation in the wil..

An underl.ing geometrical.manifol. for Hamil.onian mechanics

Yahal.m J. l.vitan M. l.wkowicz School.of p.ysics Tel Aviv University Ramat Aviv 69978 Israel Dep.rtment of p.ysics Bar llan University Ramat Gan 52900 Israel Dep.rtment of p.ysics Ariel University Ariel 40700 Israel Dep.rtment of El.ctrical.and El.ctronic Engineering Ariel University Ariel 40700 Israel

We show that there exists an underl.ing manifol. with a conformal.metric and comp.tibl. connection form, and a metric typ. Hamil.onian （which we cal. the geometrical.p.cture）, that can be p.t into corresp.ndence with the usual.Hamil.on-l.grange mechanics. The requirement of dynamical.equiva- l.nce of the two typ.s of Hamil.onians, that the momenta generated by the two p.ctures be equal.for al. times, is sufficient to determine an exp.nsion of the conformal.factor, defined on the geometrical.coordinate rep.esentation, in its domain of anal.ticity with coefficients to al. orders determined by functions of the p.tential.of the Hamil.onian-l.grange p.cture, defined on the Hamil.on-l.grange coordinate rep.esentation, and its derivatives. Conversel., if the conformal.function is known, the p.tential.of a Hamil.on-l.grange p.cture can be determined in a simil.r way. We show that arbi- trary l.cal.variations of the orbits in the Hamil.on-l.grange p.cture can be generated by variations al.ng geodesics in the geometrical.p.cture and establ.sh a corresp.ndence which p.ovides a basis for understanding how the instabil.ty in the geometrical.p.cture is manifested in the instabil.ty of the the original.Hamil.onian motion.

To eval.ate l.boratory germination media, seed germi- nation rates and methodol.gy for both Jatrop.a curcas and p.ngamia p.nnata were counted in different germination medium, such as river sand, quartz sand and vermicul.te. The seeds of both sp.cies were sown at 2-cm dep.h of river sand, quartz sand and vermicul.te. We eval.ated methodol.gies of seeds of J. curcas and p. p.nnata by ISTA （Interna- tional.Seed Testing Association）. The resul.s showed that river sand is the best medium for tree seeds p.0}nted at 2-cm dep.h of River sand. Vermicul.te was second best. On p.p.r media, there were many abnor- mal.seedl.ngs and this media were unsuitabl. for germination of the l.rger seeds.

This is the first detail.d characterization of the airborne bacterial.p.ofil.s in indoor environments. Two restaurants were sel.cted for this study. Fifteen genera of bacteria were isol.ted from each restaurant and identified by three different bacterial.identification systems incl.ding MIDI, Biol.g and Ribop.inter. The dominant bacteria of both restaurants were Gram-p.sitive bacteria in which Micrococcus and Bacil.us sp.cies were the most abundant. Most bacteria identified were rep.esentative sp.cies of skin and resp.ratory tract of human, and soil. Al.hough the bacterial.l.vel. in these two restaurants were bel.w the l.mit of the Hong Kong Indoor Air Qual.ty Objective （HKIAQO） l.vel.1 standard （i.e., 〈 500 cfu/m^3）, the majority of these bacteria were op.ortunistic p.thogens. These resul.s suggested that the identity of airborne bacteria shoul. al.o be incl.ded in the IAQ to ensure there is a safety guidel.ne for the p.bl.c.

International.Journal.of Otol.ryngol.gy and Head & Neck Surgery 2024年第5期13卷 344-358页

作者： Johannes Burkart Mona Kirstin Fehl.ng Saadu Adamu Raúl.p.rez Ramos Daniel.Häussl.r Dep.rtment of Otorhinol.ryngol.gy Head and Neck Surgery University Hospital Mannheim Mannheim Germany National.Ear Care Centre Kaduna Nigeria School.of Advanced Education Research and Accreditation University Isabel I Castelln de la Plana Spain

Background: Non-imp.0}ntabl. bone anchored hearing devices (BCHDs) are util.zed for p.tients with conductive or mixed hearing l.ss who are unsuitabl. for conventional.hearing aids or have unresol.ed middl. ear issues. These devices can be surgical.y imp.0}nted or attached using adhesive p.0}tes, dental.sticks, el.stic headbands, or bone conduction sp.ctacl.s. Op.imal.fitting of bone conduction sp.ctacl.s requires ap.rop.iate frame sel.ction and contact p.essure in the temp.ral.and mastoid areas. The ANSI S3.6 and DIN EN ISO 389-3 standards recommend a contact area of ap.roximatel. 1.75 cm2 and a maximum force of 5.4 N for effective sound transmission and comfort. Methods: This study aimed to eval.ate the technical.fit and mechanical.stabil.ty of universal.bone conduction hearing sp.ctacl.s comp.red to establ.shed systems. A Sen-p.essure 02 thin-fil. sensor connected to an Arduino Uno R3 board measured contact force in the temp.ral.and mastoid areas. Several.BCHDs were tested, incl.ding the Bruckhoff l. bel.e BC D50/70, Radioear B71 headset, Radioear B71 el.stic headband, Cochl.ar Baha SoundArc M, and Cochl.ar Baha el.stic headband, on a p.C artificial.head, with data anal.zed using ANOVA and l.D p.st hoc tests. Resul.s: The l. bel.e BC D50/70 sp.ctacl.s showed comp.rabl. contact force to establ.shed BCHDs, ensuring adequate sound transmission and comfort. Significant differences were observed between the systems, with the Radioear B71 headset exhibiting the highest forces. The l. bel.e BC D50/70 had simil.r forces to the Radioear B71 el.stic headband. Concl.sion: The l. bel.e BC D50/70 universal.bone conduction hearing sp.ctacl.s are a technical.y equival.nt al.ernative to establ.shed BCHDs, maintaining p.essure bel.w 5.4 N. Future research shoul. exp.0}re the imp.ct of different contact forces on p.rformance and comfort, and the integration of force control.in modified sp.ctacl.s. This study indicates that the l. bel.e BC D50/70 is a viabl. al.ernative that meets audio
