Los claroscuros de la sincronización internacional de los ciclos económicos: evidencia sobre la manufactura de México

Se analiza la sincronización de las fluctuaciones cíclicas de la división manufacturera de México con el ciclo estadounidense. Se utiliza el enfoque tradicional de los ciclos de crecimiento para el periodo 1980-2004 en submuestras de cinco años que se desplazan en el tiempo, lo cual permite estudiar la evolución temporal del proceso. Los resultados sugieren que la sincronización se ha incrementado sustancialmente en el marco del TLCAN, pero ha sido heterogénea, pues el comercio exterior puede haber sido un mecanismo de transmisión fundamental en el proceso. También se muestra que las actividades más integradas al exterior son más vulnerables a los choques externos, lo cual puede constituir una debilidad de la nueva estrategia de desarrollo

Treating the face of women with botulinum toxin type A: 7-year review

Introduction: Botulinum toxin type A (BTX-A) is the number one aesthetic procedure worldwide, and the difficulty in standardizing the aesthetic treatment of the face results in a broad range of treatment possibilities. The objective this study aimed to describe the author’s experience treating facial wrinkles of women with BTX-A and suggest a standardized initial treatment method. Methods: A documentary retrospective review of all medical records from the main author’s clinic from 2010 to 2017 in São Paulo, Brazil, was performed, searching for female patients who required the BTX-A aesthetic treatment to reduce facial wrinkles. The main author obtained, reviewed, and classified photographic data (“Carruthers Grading Scale for Forehead Lines”). Results: The BTX-A used in all patients was Botox® (Allergan Inc., Irvine, CA, USA). A total of 156 female treatments with BTX-A were identified. The average total units of BTX-A used for the referred treatment was 32.43U. The average period between treatments in the same patient was 8.73 months. All patients showed an improved “Grading Scale for Forehead Lines” post-treatment Conclusion: The review suggests a safe and effective technique is possible with even lower complication rates than found in the literature using fewer units, resulting in lower product costs. One should always try to minimize risks in aesthetic treatments

Técnica de mastopexia sem demarcação prévia idealizada pelo Dr. Millan: descrição da técnica e avaliação do nível de satisfação

Introdução: Diferentes técnicas cirúrgicas foram desenvolvidas para a redução do volume glandular e para a correção da ptose mamária com o objetivo de obter resultados eficientes e de qualidade com o menor número de complicações possível. Este artigo descreve a técnica de mastopexia idealizada pelo Dr. Roberto Antonio Barjaz Millan e a avaliação do nível de satisfação das mulheres após o procedimento. Métodos: Trata-se de um estudo transversal, observacional e analítico desenvolvido a partir da análise da técnica de mastopexia na redução mamária e na correção de ptose mamária padronizada pelo Dr. Millan, realizado no Setor de Cirurgia Plástica do Centro Universitário Saúde ABC. Participaram do estudo 20 mulheres com ptose mamária grau II e III, segundo classificação de Regnault, ou hipertrofia mamária, definida pelos critérios de Sacchini et al. e de Franco & Rebello, ainda não submetidas a cirurgia e 20 mulheres previamente submetidas a mastopexia pela técnica de Millan, com idades entre 18 e 60 anos. Para análise do nível de satisfação após o procedimento, foi aplicado o questionário BREAST-Q®. Resultados: Não houve diferenças significantes das mulheres que fizeram a cirurgia (grupo pós-cirúrgico) quando comparadas às que não fizeram cirurgia (grupo controle) em relação às variáveis idade (p=0,357), Índice de Massa Corporal (p=0,695), grau de hipertrofia (p=0,799) e grau de ptose mamária (p=0,391). Em relação às variáveis de satisfação com mamas, psicossocial, sexual, físico, todas as pacientes submetidas a cirurgia apresentaram valores maiores comparados aos valores obtidos nas pacientes do grupo sem cirurgia (p<0,009). Conclusão: A técnica de mastopexia idealizada pelo Dr. Millan apresenta resultados que foram considerados satisfatórios pelas pacientes avaliadas

The mastopexy technique without preoperative markings idealized by Dr. Millan: description of the technique and patient satisfaction evaluation

Introduction: Different surgical techniques were developed to reduce glandular volume and correct breast ptosis, with the objective of efficient and quality results for the patients and with the fewest possible complications. This study describes the treatment technique standardized by Dr. Roberto Millan and the level of women’s satisfaction after performing the procedure. Methods: This is a cross-sectional, observational and analytical study carried out from the analysis of the breast treatment technique standardized by Dr. Millan performed at the Plastic Surgery Sector of Centro Universitário Saúde ABC. The study included 20 women with grade II and III breast ptosis, according to Regnault’s classification, or breast hypertrophy, defined by the criteria of Sacchini et al. and by Franco & Rebello; and 20 women previously submitted to mastopexy or reduction mammoplasty using the Millan technique, aged between 18 and 60 years. The BREAST-Q® questionnaire was applied to analyze the level of satisfaction after the procedure. Results: It is observed that there were no significant differences between women who underwent the surgery Mass group (post-surgical group) when compared to those who did not undergo surgery (control group) concerning age (p=357), (p=0.695), degree of hypertrophy (p=0.799) and degree of breast ptosis (p=0.391). Regarding breast satisfaction, psychosocial, sexual, and physical variables all presented higher values in women with surgery than those without surgery (p<0.009). Conclusion: The breast treatment technique standardized by Dr. Millan presents results that led to patient satisfaction

Measurement of the effective Bs0→J/ψKS0 lifetime

This paper reports the first measurement of the effective B0 s → J /ψK0 S lifetime and an updated mea- surement of its time-integrated branching fraction. Both measurements are performed with a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions, recorded by the LHCb experiment in 2011 at a centre-of-mass energy of 7 TeV. The results are: τ eff J /ψK0 S = 1.75 ± 0.12 (stat) ± 0.07 (syst) ps and B(B0 s → J /ψK0 S ) = (1.97 ± 0.23) × 10−5. For the latter measurement, the uncertainty includes both statistical and systematic sources

Search for direct CP violation in D0→h-h+ modes using semileptonic B decays

A search for direct CP violation in D0 → h−h+ (where h = K or π ) is presented using data corresponding to an integrated luminosity of 1.0 fb−1 collected in 2011 by LHCb in pp collisions at a centre-of-mass energy of 7 TeV. The analysis uses D0 mesons produced in inclusive semileptonic b-hadron decays to the D0μX final state, where the charge of the accompanying muon is used to tag the flavour of the D0 meson. The difference in the CP-violating asymmetries between the two decay channels is measured to be ACP = ACP (K − K +) − ACP (π −π +) = (0.49 ± 0.30 (stat) ± 0.14 (syst))%

Search for D(s)+→π+μ+μ- and D(s)+→π-μ+μ+ decays

A search for non-resonant D+ (s) → π +μ+μ− and D+ (s) → π −μ+μ+ decays is performed using proton- proton collision data, corresponding to an integrated luminosity of 1.0 fb−1, at √s = 7 TeV recorded by the LHCb experiment in 2011. No signals are observed and the 90% (95%) confidence level (CL) limits on the branching fractions are found to be B(D+ → π +μ+μ−) < 7.3 (8.3) × 10−8, B(D+ s → π +μ+μ−) < 4.1 (4.8) × 10−7, B(D+ → π −μ+μ+) < 2.2 (2.5) × 10−8, B(D+ s → π −μ+μ+) < 1.2 (1.4) × 10−7. These limits are the most stringent to dat

Measurements of the Λb0→J/ψΛ decay amplitudes and the Λb0 polarisation in pp collisions at s=7 TeV

An angular analysis of Λ0 b → J /ψΛ decays is performed using a data sample corresponding to 1.0 fb−1 collected in pp collisions at √s = 7 TeV with the LHCb detector at the LHC. A parity violating asymmetry parameter characterising the Λ0 b → J /ψΛ decay of 0.05 ± 0.17 ± 0.07 and a Λ0 b transverse production polarisation of 0.06 ± 0.07 ± 0.02 are measured, where the first uncertainty is statistical and the second systemati

Differential branching fraction and angular analysis of the decay B 0 → K ∗0 μ + μ -

The angular distribution and differential branching fraction of the decay B 0→ K ∗0 μ + μ − are studied using a data sample, collected by the LHCb experiment in pp collisions at s√=7 TeV, corresponding to an integrated luminosity of 1.0 fb−1. Several angular observables are measured in bins of the dimuon invariant mass squared, q 2. A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be q20=4.9±0.9GeV2/c4 , where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions

Search for the rare decay D0→μ+μ-

A search for the rare decay D0 → μ+μ− is performed using a data sample, corresponding to an integrated luminosity of 0.9 fb−1, of pp collisions collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The observed number of events is consistent with the background expectations and corresponds to an upper limit of B(D0 → μ+μ−) < 6.2 (7.6) × 10−9 at 90% (95%) confidence level. This result represents an improvement of more than a factor twenty with respect to previous measurement
