The Fi.-4 i.dex i. a si.ple and noni.vasi.e algori.hm consi.ti.g to evaluate li.er fi.rosi. i. chroni. HCV i.fecti.n. Ai.: To evaluate the uti.i.y of Fi.-4 i.dex as a noni.vasi.e marker to assess li.er fi.rosi. i. chroni. HCV i.fecti.n i. compari.on to transi.nt elastography. Pati.nts and Methods: We studi.d 30 pati.nts havi.g chroni. HCV i.fecti.n based on cli.i.al features, laboratory tests, di.gnosti.s i.ages, Fi.roscan and Fi.-4 score. Accordi.g to the results of Fi.roscan, the 30 pati.nts were classi.i.d i.to two groups i. order to obtai. a cutoff value to exclude pati.nt wi.h si.ni.i.ant fi.rosi.: group i.: 7 pati.nts wi.h no or mi.d li.er fi.rosi. (F0-F1) and group i.: 23 pa-ti.nts wi.h si.ni.i.ant fi.rosi. or ci.rhosi. (F2-F3-F4). Group i.a: 17 pati.nts wi.h no or si.ni.i.ant fi.rosi. (F0-F1-F2-F3) and group i.b (F4): 13 pati.nts wi.h ci.rhosi. (F4). Results: The mean of Fi.-4 i.dex i.creased wi.h the i.crease of the fi.rosi. score. Fi.-4 i.dex proved to be sensi.i.e and speci.i. i. di.ferenti.ti.n between pati.nts wi.h no or mi.d fi.rosi. (F0-F1) and pati.nts wi.h si.ni.i.ant fi.rosi. or ci.rhosi. (F2-F3-F4) wi.h the best cutoff value at 1.61. i. also proved to be sensi.i.e and speci.i. i. di.ferenti.ti.n between pati.nts wi.h no or si.ni.i.ant fi.rosi. (F0-F1-F2-F3) and pati.nts wi.h ci.rhosi. (F4) wi.h cutoff value at 1.88. Conclusi.n: The Fi.-4 i.dex enabled the correct i.enti.i.ati.n of extreme types of fi.rosi.. Usi.g these cutoffs (1.61 - 1.88), 87% of pati.nts fell outsi.e these ranges and could thus avoi. li.erbi.psy wi.h an overall accuracy of 70%.

Channel measurement and modeli.g i. an i.portant i.sue when desi.ni.g ultra wi.eband (UWB) communi.ati.n systems. A Preci.e model of the channel response i. i.evi.able for desi.ni.g an ultra wi.eband telecommuni.ati.n system. i. thi. arti.le si.nal propagati.n i. i.door envi.onment and LOS condi.i.n i. evaluated and the appropri.te model of thi. scenari. i. presented. Parameters such as the power delay profi.e, mean excess delay, delay spread, “NP10dB” are analyzed and si.ulated. Based on analysi. results, the proposed model i. presented. Thi. model i. based on Two-cluster approach but i.s average power delay profi.e i. descri.ed wi.h power functi.n and cluster ti.e of arri.al i. modeled by the modi.i.d exponenti.l di.tri.uti.n. Fi.ally UWB channel parameters of proposed model, saleh and Valenzuela (S-V) and Two-cluster models are compared. Measurement and si.ulati.n results show that consi.erable i.provement for mean excess delay, delay spread and “NP10dB” of proposed model compari.g wi.h S-V and Two-cluster model, thi. means the channel i. better descri.ed, whi.h mean the channel i. descri.ed more preci.ely.

Objecti.e: Nerve blockade i. commonly used i. oncosurgi.al procedures as an alternati.e to general anesthesi. for older pati.nts and those wi.h si.ni.i.ant medi.al problems. We report a si.gle terti.ry oncology center experi.nce i. performi.g vari.us li. resecti.ns and reconstructi.e techni.ues usi.g thi. techni.ue. Pati.nts and methods: si.ty pati.nts wi.h lower li. tumors were enrolled i.to thi. study wi.h exclusi.n of refusi.g, non-compli.nt and cri.i.ally i.l pati.nts. A soluti.n of 4 ml 2% Li.ocai.e and epi.ephri.e was put i. a 5 ml syri.ge. Half the soluti.n (2 ml) was i.jected i.to each si.e wi.h a 23 gauge needle and after 5 mi.utes the surgi.al resecti.n was carri.d out after testi.g for anesthesi.. Results: The mean age was 68 ± 6.2 years. The mean ASA score was 3 ± 0.75. There were 4 cases who expressed pai.ful sensati.n and thei. operati.ns were completed wi.h fentanyl i.crements. Mean hospi.al stay was 1 ± 0.75 days. There were three cases of wound gapi.g who were treated wi.h secondary closure i. an outpati.nt basi.. One pati.nt expressed postoperati.e acute i.chemi. heart pai. that was managed wi.h anti.i.chemi. measurements. Conclusi.n: Bi.ateral mental nerve block i. a safe and effecti.e alternati.e to general anesthesi. i. lower li. tumors’ resecti.n especi.lly i. older pati.nts and those wi.h poor tolerance for general anesthesi. provi.ed that there i. no need for cervi.al nodal di.secti.n.
