Right circumcaval ureter and double right renal vein in the Brazilian shorthair cat (Felis catus): two case reports

Variations of the renal veins are well described in the literature, although variations concerning the ureter are considered a rare finding in cats. The circumcaval ureter is one of the rarest variations of the ureter and is characterised by a loop of the ureter posterior to the caudal vena cava. This variant is also known as preureteral vena cava and retrocaval ureter. It is thought to be caused by a deviation during embryonic development of the aforementioned vein. Due to its rarity, there are scarce reports of the circumcaval ureter in cats, and its association with two renal veins makes it less common as well. These variations should be preoperatively identified in order to avoid complications in kidney transplants, ureteral surgeries and cystoscopies, for instance. The present work aims to report two cases of a circumcaval ureter with two renal veins in two different Brazilian shorthair cats (Felis catus)

Is there a difference between the right and left kidney? A macroscopic approach in Brazilian Shorthair Cat

ABSTRACT The aim of this study was to characterize the renal morphology and anatomical variations of the renal pedicle in domestic shorthaired cats. Dissections were performed in 40 adult cats, obtained from the necropsy unit without macroscopic renal pathology. Kidney dimensions (length, width, and thickness) and the length and origin of the renal arteries and main branches were measured. The length, width and thickness of the right kidney (cm) were 3.83±0.46, 2.42±0.22, and 2.22±0.33 in males, and 3.61±0.53, 2.28±0.38, and 2.13±0.40 in females, respectively. In the left kidney, these measures were 3.82±0.32, 2.48±0.31, and 2.37±0.32 in males, and 3.48±0.47, 2.39±0.26, and 2.15±0.34 in females, respectively. The left kidneys of males were significantly bigger than those of females. There was a positive linear correlation between the rostrum-sacral length and ellipsoid volume of the left kidney only in males. Most of the kidneys were situated ventrally between the third to fifth lumbar vertebras. The right renal artery was situated ventrally to third lumbar vertebra and the left artery to the fourth. The results of the present study contribute to the field of comparative and applied anatomy

Measurement of D-0, D+, D+* and D-s(+) production in pp collisions at root s=5.02 TeV with ALICE

The measurements of the production of prompt D , D + , D 17 + , and Ds+ mesons in proton\u2013proton (pp) collisions at s=5.02TeV with the ALICE detector at the Large Hadron Collider (LHC) are reported. D mesons were reconstructed at mid-rapidity (| y| < 0.5) via their hadronic decay channels D \u2192 K - \u3c0 + , D + \u2192 K - \u3c0 + \u3c0 + , D 17 + \u2192 D \u3c0 + \u2192 K - \u3c0 + \u3c0 + , Ds+\u2192\u3d5\u3c0+\u2192K+K-\u3c0+, and their charge conjugates. The production cross sections were measured in the transverse momentum interval 0<36GeV/c for D , 1<36GeV/c for D + and D 17 + , and in 2<24GeV/c for Ds+ mesons. Thanks to the higher integrated luminosity, an analysis in finer p T bins with respect to the previous measurements at s=7TeV was performed, allowing for a more detailed description of the cross-section p T shape. The measured p T -differential production cross sections are compared to the results at s=7 TeV and to four different perturbative QCD calculations. Its rapidity dependence is also tested combining the ALICE and LHCb measurements in pp collisions at s=5.02TeV. This measurement will allow for a more accurate determination of the nuclear modification factor in p\u2013Pb and Pb\u2013Pb collisions performed at the same nucleon\u2013nucleon centre-of-mass energy

Calibration of the photon spectrometer PHOS of the ALICE experiment

The procedure for the energy calibration of the high granularity electromagnetic calorimeter PHOS of the ALICE experiment is presented. The methods used to perform the relative gain calibration, to evaluate the geometrical alignment and the corresponding correction of the absolute energy scale, to obtain the nonlinearity correction coefficients and finally, to calculate the time-dependent calibration corrections, are discussed and illustrated by the PHOS performance in proton-proton (pp) collisions at s=13 TeV. After applying all corrections, the achieved mass resolutions for \u3c00 and \u3b7 mesons for pT > 1.7 GeV/c are \u3c3m\u3c0javax.xml.bind.JAXBElement@533d1c3d = 4.56 \ub1 0.03 MeV/c2 and \u3c3m\u3b7 = 15.3 \ub1 1.0 MeV/c2, respectively

Energy dependence of exclusive J/ photoproduction off protons in ultra-peripheral p-Pb collisions at NN=5.02 TeV

The ALICE Collaboration has measured the energy dependence of exclusive photoproduction of J / \u3c8 vector mesons off proton targets in ultra\u2013peripheral p\u2013Pb collisions at a centre-of-mass energy per nucleon pair sNN=5.02 TeV. The e + e - and \u3bc + \u3bc - decay channels are used to measure the cross section as a function of the rapidity of the J / \u3c8 in the range - 2.5 < y< 2.7 , corresponding to an energy in the \u3b3p centre-of-mass in the interval 40 < W \u3b3p < 550 GeV. The measurements, which are consistent with a power law dependence of the exclusive J / \u3c8 photoproduction cross section, are compared to previous results from HERA and the LHC and to several theoretical models. They are found to be compatible with previous measurements

Relative particle yield fluctuations in Pb-Pb collisions at root s(NN)=2.76 TeV

First results on K / \u3c0, p / \u3c0 and K/p fluctuations are obtained with the ALICE detector at the CERN LHC as a function of centrality in Pb--Pb collisions at 1asNN=2.76TeV. The observable \u3bd dyn , which is defined in terms of the moments of particle multiplicity distributions, is used to quantify the magnitude of dynamical fluctuations of relative particle yields and also provides insight into the correlation between particle pairs. This study is based on a novel experimental technique, called the Identity Method, which allows one to measure the moments of multiplicity distributions in case of incomplete particle identification. The results for p / \u3c0 show a change of sign in \u3bd dyn from positive to negative towards more peripheral collisions. For central collisions, the results follow the smooth trend of the data at lower energies and \u3bd dyn exhibits a change in sign for p / \u3c0 and K/p
