Outcome of Endoscopic Variceal Band Ligation

Introduction: Bleeding from esophageal varices in cirrhosis is an emergent condition with high mortality. One of the preferred modality of treating esophageal varices is EVL. We aimed to find out the outcome of EVL in controlling acute esophageal variceal bleeding, prophylactic banding to prevent future bleeding and the number of sessions required for complete eradication of varices. Methods: This descriptive observational study was carried out in Gastroenterology and Hepatology unit of Bir Hospital, NAMS from June 2016 to May 2017. Consecutive cases who presented in emergency room with acute variceal bleeding due to liver cirrhosis and cases of liver cirrhosis with large varices and red color signs on endoscopic examination were enrolled. They underwent EVL and subsequent re-endoscope at one month interval till the eradication of varices was achieved.  Results: Among 83 patients, 15 (18.1%) were of Child Pugh class A, 29 (34.9%) B and 39 (47%) were of C. In 20 (24.1%) cases varices could be eradicated in one session of EVL while 57 (68.7%) required two sessions and in 6 (7.2%) cases it took three sessions. Total average EVL session required for obliteration of esophageal varices was 1.84±0.53. There was only one (1.2%) of early re-bleeding post EVL. Conclusions: EVL is an effective modality of treatment in controlling acute esophageal variceal bleeding, in preventing future variceal bleeding as well as in eradicating esophageal varices, with very few complications.

Synthesis and spectroscopic characterisation of a new class of heterobimetallic zirconocene(IV) compounds

Reactions of Cp2ZrCl2 with homometallic complexes of aluminium containing one residual hydroxy group Al(OGO)(OGOH) and Al(L)(OGOH) [where G=G1=CMe2CMe2(1a); G=G2=CMe2CH2CHMe (1b); G= G3=CMe2CH2CH2CMe2(1c) and L=L1=OC6H4CH=NCH2CH2O, G=G1(2a); L=L1, G=G2(2b); L=L1, G=G3(2c); L=L2=OC10H6 CH=NCH2CH2O, G=G1(2d); L=L2, G=G2(2e); L=L2, G=G3(2f)] in THF using Et3N as HCl acceptor affords novel heterobimetallic compounds of the types Al(OGO)2Zr(Cl)Cp2 and Al(L)(OGO)Zr(Cl)Cp2, respectively. All of these derivatives have been characterised by elemental analyses, molecular weight measurements, and spectroscopic [IR, NMR (1H and 27Al)] studies

Measurements of the azimuthal anisotropy of prompt and nonprompt charmonia in PbPb collisions at sNN\sqrt{s_\mathrm{NN}} = 5.02 TeV

International audienceThe second-order ($v_2$) and third-order ($v_3$) Fourier coefficients describing the azimuthal anisotropy of prompt and nonprompt (from b-hadron decays) J/$\psi$, as well as prompt $\psi$(2S) mesons are measured in lead-lead collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV. The analysis uses a data set corresponding to an integrated luminosity of 1.61 nb$^{-1}$ recorded with the CMS detector. The J/$\psi$ and $\psi$(2S) mesons are reconstructed using their dimuon decay channel. The $v_2$ and $v_3$ coefficients are extracted using the scalar product method and studied as functions of meson transverse momentum and collision centrality. The measured $v_2$ values for prompt J/$\psi$ mesons are found to be larger than those for nonprompt J/$\psi$ mesons. The prompt J/$\psi$$v_2$ values at high $p_\mathrm{T}$ are found to be underpredicted by a model incorporating only parton energy loss effects in a quark-gluon plasma medium. Prompt and nonprompt J/$\psi$ meson $v_3$ and prompt $\psi$(2S) $v_2$ and $v_3$ values are also reported for the first time, providing new information about heavy quark interactions in the hot and dense medium created in heavy ion collisions

Measurements of the azimuthal anisotropy of prompt and nonprompt charmonia in PbPb collisions at sNN \sqrt{s_{\textrm{NN}}} = 5.02 TeV

The second-order (v$_{2}$) and third-order (v$_{3}$) Fourier coefficients describing the azimuthal anisotropy of prompt and nonprompt (from b-hadron decays) J/ψ, as well as prompt ψ(2S) mesons are measured in lead-lead collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_{\textrm{NN}}}$ = 5.02 TeV. The analysis uses a data set corresponding to an integrated luminosity of 1.61 nb$^{−1}$ recorded with the CMS detector. The J/ψ and ψ(2S) mesons are reconstructed using their dimuon decay channel. The v$_{2}$ and v$_{3}$ coefficients are extracted using the scalar product method and studied as functions of meson transverse momentum and collision centrality. The measured v$_{2}$ values for prompt J/ψ mesons are found to be larger than those for nonprompt J/ψ mesons. The prompt J/ψ v$_{2}$ values at high p$_{T}$ are found to be underpredicted by a model incorporating only parton energy loss effects in a quark-gluon plasma medium. Prompt and nonprompt J/ψ meson v$_{3}$ and prompt ψ(2S) v$_{2}$ and v$_{3}$ values are also reported for the first time, providing new information about heavy quark interactions in the hot and dense medium created in heavy ion collisions.[graphic not available: see fulltext
