Gastrointestinal pathologistsâ perspective on managing risk in the distal esophagus: convergence on a pragmatic approach
Here, we discuss recent updates and a continuing controversy in the diagnosis and management of Barrett’s esophagus, specifically the recommendation that the irregular Zâ line not be biopsied, the diminished status of ultrashortâ segment Barrett’s esophagus, the evidence basis for excluding and including the requirement of goblet cells for the diagnosis of Barrett’s esophagus, and the conclusion that histologically confirmed lowâ grade dysplasia is best managed with endoscopic ablation rather than surveillance. We reference the American Gastroenterological Association and College of Gastroenterology and the British Society of Gastroenterology guidelines throughout, with the thesis that the field is converging on the concept of applying scarce medical resources to the diagnosis, surveillance, and therapy of patients most likely to derive benefit.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146991/1/nyas13680.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146991/2/nyas13680_am.pd
Systemic inflammatory response – antiinflamatory strategies in cardiac surgery
IMSP Spitalul Clinic RepublicanOperaţiile pe inimă deseori se asociază cu dezvoltarea sindromului de răspuns inflamator sistemic. Acest fenomen este variabil clinic şi poate
fi determinat în condiţii de laborator prin aprecierea indicilor principali de inflamaţie, cum sânt - complementul, citokinele şi factorii de
adgezie. Luând în consideraţie că sindromul inflamator poate afecta organele majore, în ultimul timp are loc dezvoltarea vertiginoasă a
strategiilor antiinflamatori având ca scop diminuarea răspunsului inflamator sistemic.
Scopul acestui articol este de a sistematiza literatura mondială recentă consacrată problemei sus numite. În particular, sânt elucidate
efectele antiinflamatori a by-pass-ului aortocoronarian fără circulaţie extracorporală (CEC), hemofiltrarea, filtraţia leucocitară, utilizarea
corticosteroizilor, aprotininei, inhibitorilor fosfodiesterazei, dopexaminului, H2 antagonişti, şi blocatorilor enzimelor de conversie.It’s generally accepted that cardiac surgery is frequently associated with the development of systemic inflammatory response. This fhenomenon is very variable clinically, and can be detected by measuring plasma concentrations of certain inflammatory markers. Complement
component, cytokines and adhesin molecules are examples of these markers. Systemic inflammation can be potentially damaging to major
organs. Several anti-inflammatory strategies have been used in recent years, aiming to attenuate the development of systemic inflammatory
response. This article summarizes recently published literature concerning the use of anti-inflammatory techiques and farmacological
agents in cardiac surgery. In particular, the anti-inflammatory effects of off-pump surgery, leucocyte filtration, corticosteroids, aprotinin,
phoshodiesterase inhibitors, dopexamine, H2 antagonists and ACE inhibitors are reviewed. The overall conclusion is that although certain
strategies reduce plasma levels of inflammatory mediators, convicing evidence of sugnificant clinical benefits is yet to come
Transition probabilities in the X(5) candidate Ba
To investigate the possible X(5) character of 122Ba, suggested by the ground
state band energy pattern, the lifetimes of the lowest yrast states of 122Ba
have been measured, via the Recoil Distance Doppler-Shift method. The relevant
levels have been populated by using the 108Cd(16O,2n)122Ba and the
112Sn(13C,3n)122Ba reactions. The B(E2) values deduced in the present work are
compared to the predictions of the X(5) model and to calculations performed in
the framework of the IBA-1 and IBA-2 models
Transition rates and nuclear structure changes in mirror nuclei 47Cr and 47V
Lifetime measurements in the mirror nuclei 47Cr and 47V were performed by
means of the Doppler-shift attenuation method using the multidetector array
EUROBALL, in conjunction with the ancillary detectors ISIS and the Neutron
Wall. The determined transition strengths in the yrast cascades are well
described by full pf shell model calculations.Comment: Latex2e, 11 pages, 3 figure

Identification of the crossing point at N=21 between normal and intruder configurations
The beta(-) decay of Mg-34 was used to study the Al-34 nucleus through. spectroscopy at the Isotope Separator On-Line facility of CERN. Previous studies identified two beta-decaying states in Al-34 having spin-parity assignments J(pi) = 4(-) dominated by the normal configuration pi(d(5/2))(-1)circle times nu(f(7/2)) and J(pi) = 1(+) by the intruder configuration pi(d(5/2))(-1) circle times nu(d(3/2))(-1) (f(7/2))(2). Their unknown ordering and relative energy have been the subject of debate for the placement of Al-34 inside or outside the N = 20 "island of inversion." We report here that the 1(+) intruder lies only 46.6 keV above the 4(-) ground state. In addition, a new half-life of T-1/2 = 44.9(4) ms, that is twice as long as the previously measured 20(10) ms, has been determined for Mg-34. Large-scale shell-model calculations with the recently developed SDPF-U-MIX interaction are compared with the new data and used to interpret the mechanisms at play at the very border of the N = 20 island of inversion.Peer reviewe
Beta-delayed proton emission from 20Mg
Beta-delayed proton emission from 20 Mg has been measured at ISOLDE, CERN, with the ISOLDE Decay Station (IDS) setup including both charged-particle and gamma-ray detection capabilities. A total of 27 delayed proton branches were measured including seven so far unobserved. An updated decay scheme, including three new resonances above the proton separation energy in 20 Na and more precise resonance energies, is presented. Beta-decay feeding to two resonances above the Isobaric Analogue State (IAS) in 20 Na is observed. This may allow studies of the 4032.9(2.4)keV resonance in 19 Ne through the beta decay of 20 Mg, which is important for the astrophysically relevant reaction 15O( , )19Ne . Beta-delayed protons were used to obtain a more precise value for the half-life of 20 Mg, 91.4(1.0)ms
Transfer Reaction Studies with Spectrometers
The revival of transfer reaction studies benefited from the construction of the new generation large solid angle spectrometers, coupled to large gamma arrays. The recent results of gamma-particle coincident measurements in Ca-40+Zr-96 and Ar-40+Pb-208 reactions demonstrate a strong interplay between single-particle and collective degrees of freedom that is pertinent to the reaction dynamics. The development of collectivity has been followed in odd Ar isotopes populated in the Ar-40+Pb-208 reaction through the excitation of the 11/2(-) states, understood as the coupling of single particle degrees of freedom to nuclear vibration quanta. Pair transfer modes is another important degree of freedom which is presently being studied with Prisma in inverse kinematics at energies far below the Coulomb barrier. First results from the Zr-96+Ca-40 reaction elucidate the role played by nucleon-nucleon correlation
