| 1 | Relative peripheral refraction across 4 meridians after orthokeratology and LASIK surgery显示文摘Background:To characterize the axial and off-axis refraction across four meridians of the retina in myopic eyes before and after Orthokeratology(OK)and LASIK surgery.Methods:Sixty right eyes with a spherical equivalent(M)between−0.75 to−5.25 D(cylinder<−1.00 D)underwent LASIK(n=26)or OK(n=34)to treat myopia.Axial and off-axis refraction were measured with an open-field autorefractometer before and after stabilized treatments.Off-axis measurements were obtained for the horizontal(35°nasal and temporal retina)and vertical(15°superior and inferior retina)meridians,and for two oblique directions(45–225°and 135–315°)up to 20°of eccentricity.The refractive profile was addressed as relative peripheral refractive error(RPRE).Results:OK and LASIK post-treatment results showed an increase of myopic relative refraction at several eccentric locations.At the four meridians evaluated,the M component of the pre-treatment RPRE values was not statistically different(p>0.05)from the post-treatment RPRE within 30°and 20°of the central visual field after LASIK and OK,respectively.These results demonstrated that the treatment zone warrants an optimal central field of vision.Conclusions:The present study gives an overview of RPRE after refractive corneal reshaping treatments(OK and LASIK)across vertical,horizontal and two oblique meridians together.This allows a 3D representation of RPRE at the retina and shows that the myopic shift induced by both treatments is more relevant in horizontal directions. | António Queirós Ana Amorim-de-Sousa Daniela Lopes-Ferreira César Villa-Collar Ángel Ramón Gutiérrez JoséManuel González-Méijome | 2018 | Eye and Vision2018，5，1： | 8 |
| 2 | Epigenetic basis of Alzheimer disease显示文摘Alzheimer disease(AD)is the primary form of dementia that occurs spontaneously in older adults.Interestingly,the epigenetic profile of the cells forming the central nervous system changes during aging and may contribute to the progression of some neurodegenerative diseases such as AD.In this review,we present general insights into relevant epigenetic mechanisms and their relationship with aging and AD.The data suggest that some epigenetic changes during aging could be utilized as biomarkers and target molecules for the prevention and control of AD. | Angeles C Tecalco-Cruz JosuéO Ramírez-Jarquín María E Alvarez-Sánchez Jesus Zepeda-Cervantes | 2020 | World Journal of Biological Chemistry2020，11，2： | 4 |
| 3 | Effect of a bacterial inoculum and additive on dry matter in situ degradability of sugarcane silage显示文摘The objective of this study was to evaluate the effect of adding a bacterial inoculum and a handmade additive to sugarcane silage(SCS) on the in situ digestibility of dry matter(DM). The treatments were: T1) sugarcane silage(SCS) and T2) sugarcane silage with 1% inoculum and 1% additive(SCS+). The bacterial inoculum consisted of 10.0% molasses, 1.0% yogurt, 5.0% chicken manure, 0.5% urea, and 83.0% water, and the additive was formulated with 1.0% urea, 0.1% ammonium sulfate, and 0.25% phosphorus. In situ dry matter digestibility(DMD) was determined using the nylon bag technique with four cows equipped with ruminal fistulas. Cows were fed with ensiled sugarcane supplemented with 1 kg of commercial concentrate. 5 g of ground sample for each sugarcane treatment were weighted in nylon bags and incubated for 4, 8, 12, 24, 48, and 72 h in a completely randomized design with six replicates. The DMD(%) was higher(P<0.05) for SCS+ for all incubation times when compared with SCS. There were no differences in ruminal p H between the treatments for all the incubation times. The data suggested that the sugarcane silage with bacterial inoculum and additive could be an alternative for providing forage for ruminants during the season of low growth and quality grass. | José A Reyes-Gutiérrez Oziel D Montaez-Valdez Ramón Rodríguez-Macias Mario Ruíz-López Eduardo Salcedo-Pérez Cándido E Guerra-Medina | 2015 | Journal of Integrative Agriculture2015，14，3： | 3 |
| 4 | 在与心肌的梗塞介绍的就医的病人的心率的预示的意义显示文摘 AIM: To investigate the prognostic significance of resting heart rate in patients with acute coronary syndrome (ACS), independent of other known factors. METHODS: Patients 40 years of age or older who had been admitted with acute coronary syndrome (ACS) to one of the 94 hospitals participating in the Prevalence of Peripheral Arterial Disease in Patients with Acute Coronary Syndrome (PAMISCA) study were included. Patients were divided into two groups based on their resting heart rate (HR ≥ or < 70 bpm). Complications were recording during a follow-up period of 1 year. RESULTS: There were 1054 ACS patients analyzed (43.5% with ST segment elevation and 56.5% without elevation). Mean age was 66.6 ± 11.7 years, 70.6% were male and 29.4% of subjects were female. During follow-up, more patients in the HR ≥ 70 bpm group were hospitalized for heart failure and they also had a higher mortality rate. In the multivariate analysis, a heart rate of ≥ 70 bpm was independently related to overall mortality during the follow-up period (hazard ratio 2.5; 95% confidence interval, 1.26-4.97, P = 0.009). CONCLUSION: A resting heart rate ≥ 70 bpm in patients who survive an ACS is an indicator of a high risk of suffering cardiovascular events during follow-up. | Lorenzo Fácila Pedro Morillas Juan Quiles Federico Soria Alberto Cordero Pilar Mazón Manuel Anguita Cándido Martín-Luengo Jose Ramón Gonzalez-Juanatey Vicente Bertomeu | 2012 | World Journal of Cardiology2012，4，1： | 3 |

| 6 | Current trends of liver cirrhosis in Mexico: Similitudes and differences with other world regions显示文摘AIM To investigate the main current etiologies of cirrhosis in Mexico.METHODS We performed a cross-sectional retrospective multicenter study that included eight hospitals in different areas of Mexico. These hospitals provide health care to people of diverse social classes. The inclusion criteria were a histological, clinical, biochemical, endoscopic, or imaging diagnosis of liver cirrhosis. Data were obtained during a 5-year period(January 2012-December 2017). RESULTS A total of 1210 patients were included. The mean age was 62.5 years(SD = 12.1), and the percentages of men and women were similar(52.0% vs 48.0%). The most frequent causes of liver cirrhosis were hepatitis C virus(HCV)(36.2%), alcoholic liver disease(ALD)(31.2%), and nonalcoholic steatohepatitis(23.2%), and the least frequent were hepatitis B virus(1.1%), autoimmune disorders(7.3%), and other conditions(1.0%).CONCLUSION HCV and ALD are the most frequent causes of cirrhosis in Mexico. However, we note that non-alcoholic fatty liver disease(NAFLD) as an etiology of cirrhosis increased by 100% compared with the rate noted previously. We conclude that NAFLD will soon become one of the most frequent etiologies of liver cirrhosis in Mexico. | Nahum Méndez-Sánchez Felipe Zamarripa-Dorsey Arturo Panduro Emma Purón-González Edgar Ulises Coronado-Alejandro Carlos Alejandro Cortez-Hernández Fátima Higuera de la Tijera José Luis Pérez-Hernández Eira Cerda-Reyes Heriberto Rodríguez-Hernández Vania César Cruz-Ramón Oscar Lenin Ramírez-Pérez Nancy Edith Aguilar-Olivos Olga Fabiola Rodríguez-Martínez Samantha Cabrera-Palma Guillermo Cabrera-álvarez | 2018 | World Journal of Clinical Cases2018，6，15： | 2 |

| 8 | Polyubiquitination inhibition of estrogen receptor alpha and its implications in breast cancer显示文摘Estrogen receptor alpha(ERα) is detected in more than 70% of the cases of breast cancer. Nuclear activity of ERα, a transcriptional regulator, is linked to the development of mammary tumors, whereas the extranuclear activity of ERα is related to endocrine therapy resistance. ERα polyubiquitination is induced by the estradiol hormone, and also by selective estrogen receptor degraders, resulting in ERα degradation via the ubiquitin proteasome system. Moreover, polyubiquitination is related to the ERα transcription cycle, and some E3-ubiquitin ligases also function as coactivators for ERα. Several studies have demonstrated that ERα polyubiquitination is inhibited by multiple mechanisms that include posttranslational modifica-tions, intera-ctions with coregula-tors, a-nd forma-tion of specific protein complexes with ERα. These events are responsible for an increase in ERα protein levels and deregulation of its signaling in breast cancers. Thus, ERα polyubiquitination inhibition may be a key factor in the progression of breast cancer and resistance to endocrine therapy. | Angeles C Tecalco-Cruz Josué O Ramírez-Jarquín | 2018 | World Journal of Clinical Oncology2018，9，4： | 2 |
