Relación del peso de los cerdos al nacer y a los 21 dÃas con el peso a los 56 dÃas de edad.
Se usó un total de 1622 cerdos de los registros de 203 camadas de 3 diferentes razas para determinar las relaciones entre los pesos a los 21 dÃas y al nacer, con el peso al destete, y para estudiar la influencia de los factores de raza, sexo y año sobre los pesos al destete y antes del destete. Se encontró que las diferencias entre razas, sexo y año en los pesos al destete y antes del destete no eran significativas. El peso a los 21 dÃas de nacidos estaba más estrechamente ligado con el peso al destete que con el peso al nacerPorcicultur
Abordaje transvasto mÃnimamente invasivo versus abordaje parapatelar medial convencional en la artroplastia total de rodilla en pacientes con gonartrosis: estudio prospectivo comparativo no randomizado
Objetivos: valorar y comparar los resultados a corto plazo de la artroplastia total de rodilla realizada
mediante dos vÃas de abordaje. Material y métodos: estudio prospectivo comparativo que compara abordaje
parapatelar medial (24 pacientes) y transvasto mÃnimamente invasivo (25 pacientes) en artroplastia total de rodilla.
Se incluyeron pacientes con gonartrosis grado IV de la clasificación de Kellgren-Lawrence y se excluyeron
aquellos menores de 50 años, deformidad en varo (> 15º) o valgo (> 10º), artrosis postraumática, artritis reumatoide,
cirugÃas de revisión, osteotomÃas correctoras previas, IMC > 40 kg/m2, infección activa local o sistémica
y/o deterioro mental. Resultados: se encontraron diferencias estadÃsticamente significativas en dolor del primer y
segundo dÃa postoperatorios a favor del abordaje mÃnimamente invasivo (1º dÃa: 3,8 ± 2,5 vs. 6,7 ± 2,1; p< 0,001.
2º dÃa: 3 ± 2,1 vs. 6 ± 2; p< 0,001). Conclusiones: no existen diferencias relevantes entre ambos abordajes, por lo
que se recomienda la utilización del abordaje con el que el cirujano se encuentre más cómodo y familiarizadoAim: Assess and compare short-term outcomes of total knee arthroplasty performed using two
surgical approaches. Material and methods: a prospective study with 49 patients comparing medial parapatellar
approach (24 patients) and minimally invasive trans-vastus access (25 patients) in total knee replacement.
The patients included suffered knee osteoarthritis grade IV the Kellgren-Lawrence’s classification. Exclusion
criteria were age under 50 years, large axial deformity (varus deformity > 15° or valgus > 10°), posttraumatic
osteoarthritis, rheumatoid arthritis, revision surgeries, previous osteotomies, BMI> 40 kg/m2 and of course local
or systemic active infection and mental impairment. Results: statistically significant differences were found for
pain in first and second postoperative days for the minimally invasive approach (1st day: 3.8 ± 2.5 vs. 6.7 ± 2.1; p
<0.001. 2nd day: 3 ± 2.1 vs. 6 ± 2; p <0.001). Conclusions: there are not significant differences between mini and
standard approaches in knee replacement, so decision about which access to use in knee reconstruction surgery
depends on surgeon’s preferences
Estudio epidemiológico de parasitismo gastro-intestial hepático y pulmonar del ganado lechero del departamento del Cesar
Con la colaboración de la CompañÃa Colombiana de Alimentos Lácteos CICOLAC, se realizó un estudio sobre el parasistismo gastrointestinal, hepático y pulmonar en el ganado lechero del departamento del Cesar. Se examinaron muestras de materia fecal de 1328 animales, divididos por grupos, de acuerdo a la edad y a la estación climática reinante en el momento de la toma de las muestras. Los animales examinados pertenecÃan a 63 fincas ubicadas en 18 municipios del departamento. Se identificaron huevos pertenecientes a 12 géneros de helmintos, hallándose de la misma manera ooquistes de Eimeria. Se determinó que el 57 por ciento de los animales se encontraban infestados con helmintos gastrointestinales, el 58.5 por ciento lo estaban por coccidias, 5.5 por ciento por parásitos pulmonares y no se presentó ningún género de parásito hepático. Durante el verano el parásito predominante en animales menores de 16 meses fue el Haemonchus sp, situación que se repitió con los animales mayores de 16 meses. En invierno, en animales menores de 16 meses predominó el Strongyloides sp, siendo los Ascaris los que más se encontraron en animales mayores de 16 meses. Se discuten las razones que limitan el desarrollo ganadero del departamento del Cesar, de acuerdo con las observaciones hechas durante la realización del trabajo. Estas limitantes son: alimentación deficiente durante el verano, desconocimiento del tipo de suelo de las fincas, mal manejo de los pastos, deficiente mezcla gramÃneas-leguminosas, potreros demasiado extensos, vaqueras en malas condiciones, mezcla indiscriminada de edades y sexos en los hatos, reproductores con baja fertilidad. Se hizo una estimación de las pérdidas económicas, consecuencia de la acción del parasitismo sobre la producción láctea, arrojando el resultado de {dollar}571.260.000Ganado de leche-GanaderÃa lech
Dependence On Volume Of The Phonon Frequencies And The Ir Effective Charges Of Several Iii-v Semiconductors
The mode Grüneisen parameters of the LO and TO Raman phonons of AlN, BN, and BP, and the dependence of eT* on lattice constant have been measured by Raman scattering in a diamond anvil cell. The results for eT* are interpreted by means of pseudopotential calculations of eT* versus lattice constant. © 1983 The American Physical Society.2884579458

Genetic signatures in choline and 1-carbon metabolism are associated with the severity of hepatic steatosis
Choline metabolism is important for very low-density lipoprotein secretion, making this nutritional pathway an important contributor to hepatic lipid balance. The purpose of this study was to assess whether the cumulative effects of multiple single nucleotide polymorphisms (SNPs) across genes of choline/ 1-carbon metabolism and functionally related pathways increase susceptibility to developing hepatic steatosis. In biopsy-characterized cases of nonalcoholic fatty liver disease and controls, we assessed 260 SNPs across 21 genes in choline/1-carbon metabolism. When SNPs were examined individually, using logistic regression, we only identified a single SNP (PNPLA3 rs738409) that was significantly associated with severity of hepatic steatosis after adjusting for confounders and multiple comparisons (P=0.02). However, when groupings of SNPs in similar metabolic pathways were defined using unsupervised hierarchical clustering, we identified groups of subjects with shared SNP signatures that were significantly correlated with steatosis burden (P=0.0002). The lowest and highest steatosis clusters could also be differentiated by ethnicity. However, unique SNP patterns defined steatosis burden irrespective of ethnicity. Our results suggest that analysis of SNP patterns in genes of choline/1-carbon metabolism may be useful for prediction of severity of steatosis in specific subsets of people, and the metabolic inefficiencies caused by these SNPs should be examined further
flavour tagging using charm decays at the LHCb experiment
An algorithm is described for tagging the flavour content at production of
neutral mesons in the LHCb experiment. The algorithm exploits the
correlation of the flavour of a meson with the charge of a reconstructed
secondary charm hadron from the decay of the other hadron produced in the
proton-proton collision. Charm hadron candidates are identified in a number of
fully or partially reconstructed Cabibbo-favoured decay modes. The algorithm is
calibrated on the self-tagged decay modes and using of data collected by the LHCb
experiment at centre-of-mass energies of and
. Its tagging power on these samples of
decays is .Comment: All figures and tables, along with any supplementary material and

Measurements of long-range near-side angular correlations in TeV proton-lead collisions in the forward region
Two-particle angular correlations are studied in proton-lead collisions at a
nucleon-nucleon centre-of-mass energy of TeV, collected
with the LHCb detector at the LHC. The analysis is based on data recorded in
two beam configurations, in which either the direction of the proton or that of
the lead ion is analysed. The correlations are measured in the laboratory
system as a function of relative pseudorapidity, , and relative
azimuthal angle, , for events in different classes of event
activity and for different bins of particle transverse momentum. In
high-activity events a long-range correlation on the near side, , is observed in the pseudorapidity range . This
measurement of long-range correlations on the near side in proton-lead
collisions extends previous observations into the forward region up to
. The correlation increases with growing event activity and is found
to be more pronounced in the direction of the lead beam. However, the
correlation in the direction of the lead and proton beams are found to be
compatible when comparing events with similar absolute activity in the
direction analysed.Comment: All figures and tables, along with any supplementary material and

Study of the production of and hadrons in collisions and first measurement of the branching fraction
The product of the () differential production
cross-section and the branching fraction of the decay () is
measured as a function of the beauty hadron transverse momentum, ,
and rapidity, . The kinematic region of the measurements is and . The measurements use a data sample
corresponding to an integrated luminosity of collected by the
LHCb detector in collisions at centre-of-mass energies in 2011 and in 2012. Based on previous LHCb
results of the fragmentation fraction ratio, , the
branching fraction of the decay is
measured to be \begin{equation*} \mathcal{B}(\Lambda_b^0\rightarrow J/\psi
pK^-)= (3.17\pm0.04\pm0.07\pm0.34^{+0.45}_{-0.28})\times10^{-4},
\end{equation*} where the first uncertainty is statistical, the second is
systematic, the third is due to the uncertainty on the branching fraction of
the decay , and the
fourth is due to the knowledge of . The sum of the
asymmetries in the production and decay between and
