| 1 | A pilot study of the modulation of sirtuins on arylamine N-acetyltransferase 1 and 2 enzymatic activity显示文摘Arylamine N-acetyltransferase(NAT; E.C. 2.3.1.5) enzymes are responsible for the biotransformation of several arylamine and hydrazine drugs by acetylation. In this process, the acetyl group transferred to the acceptor substrate produces NAT deacetylation and, in consequence, it is susceptible of degradation. Sirtuins are protein deacetylases, dependent on nicotine adenine dinucleotide,which perform post-translational modifications on cytosolic proteins. To explore possible sirtuin participation in the enzymatic activity of arylamine NATs, the expression levels of NAT1, NAT2,SIRT1 and SIRT6 in peripheral blood mononuclear cells(PBMC) from healthy subjects were examined by flow cytometry and Western blot. The in situ activity of the sirtuins on NAT enzymatic activity was analyzed by HPLC, in the presence or absence of an agonist(resveratrol) and inhibitor(nicotinamide) of sirtuins. We detected a higher percentage of positive cells for NAT2 in comparison with NAT1, and higher numbers of SIRT1t cells compared to SIRT6 in lymphocytes. In situ NAT2 activity in the presence of NAM inhibitors was higher than in the presence of its substrate, but not in the presence ofresveratrol. In contrast, the activity of NAT1 was not affected by sirtuins. These results showed that NAT2 activity might be modified by sirtuins. | Eneida Turiján-Espinoza Rául Alejandro Salazar-González Edith Elena Uresti-Rivera Gloria Estela Hernández-Hernández Montserrat Ortega-Juárez Rosa Milán Diana Portales-Pérez | 2018 | Acta Pharmaceutica Sinica B2018，8，2： | 7 |
| 2 | Recombinant streptokinase vs hydrocortisone suppositories in acute hemorrhoids:A randomized controlled trial显示文摘AIM: To compare the efficacy and safety of recombinant streptokinase(rSK) vs hydrocortisone acetate-based suppositories in acute hemorrhoidal disease.METHODS: A multicenter(11 sites), randomized(1:1:1), open, controlled trial with parallel groups was performed. All participating patients gave their written,informed consent. After inclusion, patients with acute symptoms of hemorrhoids were centrally randomized to receive, as outpatients, by the rectal route, suppositories of rSK 200000 IU of one unit every 8 h(first 3 units)and afterwards every 12 h until 8 administrations were completed(schedule A), one unit every 8 h until 6 units were completed(schedule B), or 25 mg hydrocortisone acetate once every 8 h up to a maximum of 24 administrations. Evaluations were performed at 3, 5,and 10 d post-inclusion. The main end-point was the 5thday response(disappearance of pain and bleeding, and≥ 70% reduction of the lesion size). Time to response and need for thrombectomy were secondary efficacy variables. Adverse events were also evaluated.RESULTS: Groups were homogeneous with regards to demographic and baseline characteristics. Fifth day complete response rates were 156/170(91.8%; 95%CI:87.3-96.2), 155/170(91.2%; 95%CI: 86.6%-95.7%),and 46/170(27.1%; 95%CI: 20.1%-34.0%) with rSK(schedule A and B) and hydrocortisone acetate suppositories, respectively. These 64.6% and 63.9%differences(95%CI: 56.7%-72.2% and 55.7%-72.0%)were highly significant(P < 0.001). This advantage was detected since the early 3rd day evaluation(68.8% and64.1% vs 7.1% for the rSK and active control groups,respectively; P < 0.001) and was maintained even at the late 10 th day assessment(97.1% and 93.5% vs67.1% for rSK and hydrocortisone acetate, respectively;P < 0.001). Time to response was 3 d(95%CI: 2.9-3.1)for both rSK groups and 10 d(95%CI: 9.3-10.7) in the hydrocortisone acetate group. This difference was highly significant(P < 0.001). All subgroup stratified analyses(with or without thrombosis and hemorrhoid classification) showed a statistically significant advantage for the rSK groups. Thrombectomy was necessary in4/251 and 14/133 patients with baseline thrombosis in the rSK and hydrocortisone acetate groups, respectively(P < 0.001). There were no adverse events attributable to the experimental treatment.CONCLUSION: rSK suppositories showed a significant advantage over a widely-used over-the-counter hydrocortisone acetate preparation for the treatment of acute hemorrhoidal illness, as well as having an adequate safety profile. | Francisco Hernández-Bernal Georgina Castellanos-Sierra Carmen M Valenzuela-Silva Karem M Catasús-Alvarez Osmany Martínez-Serrano Odalys C Lazo-Diago Cimara H Bermúdez-Badell José R Causa-García Juan E Domínguez-Suárez Pedro A López-Saura 无 | 2015 | World Journal of Gastroenterology2015，21，23： | 2 |
| 3 | Effects of feeding yeast(Saccharomyces cerevisiae), organic selenium and chromium mixed on growth performance and carcass traits of hair lambs显示文摘Yeasts and organic minerals are used in diets to improve health, productive performance and some carcass characteristics of ruminants and non-ruminants. Thirty-two lambs(Pelibuey×Katahdin; BW=(30.55±1.67) kg; n=8) were used in a 56-d feeding experiment to study the effects of different levels of live yeast(Saccharomyces cerevisiae; yeast), selenium(Se) and chromium(Cr) mixed(Se-Cr), and a mixture of yeast-Se-Cr on growth performance and carcass traits. Animals were stratified by body weight(BW) and randomly assigned to one of four treatments: 1) control group(0.0 g kg–1 yeast); 2) yeast(1.50 g kg–1 dry matter intake(DMI) d–1); 3) Se-Cr premix(1.5 mg kg–1 DMI d–1 for each mineral); and 4) yeast-Se-Cr mixture. There were no treatment effects on final BW; whereas lambs fed Se-Cr or yeast-Se-Cr had higher(P<0.05) DMI than animals supplemented with only yeast. Average daily gain(ADG), gain:feed ratio, chop area, dorsal fat and carcass yield were similar(P>0.05) among treatment groups. In conclusion, supplementation with yeast, Se-Cr mixed or yeast-Se-Cr did not improve ADG, final BW, back fat content and carcass yield of growing of Pelibuey×Katahdin lambs. Supplementation with Se-Cr and yeast-Se-Cr increased DMI, and approximately 250 g ADG animal–1 d–1 was produced with no negative effects on growth and health of the animals. | Pedro A Hernández-García Alejandro Lara-Bueno Germán D Mendoza-Martínez José R Bárcena-Gama Fernando X Plata-Pérez Rufino López-Ordaz José A Martínez-García | 2015 | Journal of Integrative Agriculture2015，14，3： | 2 |
| 4 | Dendritic cell deficiencies persist seven months after SARS-CoV-2 infection显示文摘Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19. | Alberto Pérez-Gómez Joana Vitallé Carmen Gasca-Capote Alicia Gutierrez-Valencia María Trujillo-Rodriguez Ana Serna-Gallego Esperanza Muñoz-Muela María de los Reyes Jiménez-Leon Mohamed Rafii-El-Idrissi Benhnia Inmaculada Rivas-Jeremias Cesar Sotomayor Cristina Roca-Oporto Nuria Espinosa Carmen Infante-Domínguez Juan Carlos Crespo-Rivas Alberto Fernández-Villar Alexandre Pérez-González Luis Fernando López-Cortés Eva Poveda Ezequiel Ruiz-Mateos JoséMiguel Cisneros Sonsoles Salto-Alejandre Judith Berastegui-Cabrera Pedro Camacho-Martínez Carmen Infante-Domínguez Marta Carretero-Ledesma Juan Carlos Crespo-Rivas Eduardo Márquez JoséManuel Lomas Claudio Bueno Rosario Amaya JoséAntonio Lepe Jerónimo Pachón Elisa Cordero Javier Sánchez-Céspedes Manuela Aguilar-Guisado Almudena Aguilera Clara Aguilera Teresa Aldabo-Pallas Verónica Alfaro-Lara Cristina Amodeo Javier Ampuero María Dolores Avilés Maribel Asensio Bosco Barón-Franco Lydia Barrera-Pulido Rafael Bellido-Alba Máximo Bernabeu-Wittel Candela Caballero-Eraso Macarena Cabrera Enrique Calderón Jesús Carbajal-Guerrero Manuela Cid-Cumplido Yael Corcia-Palomo Juan Delgado Antonio Domínguez-Petit Alejandro Deniz Reginal Dusseck-Brutus Ana Escoresca-Ortega Fátima Espinosa Nuria Espinosa Michelle Espinoza Carmen Ferrándiz-Millón Marta Ferrer Teresa Ferrer Ignacio Gallego-Texeira Rosa Gámez-Mancera Emilio García Horacio García-Delgado Manuel García-Gutiérrez María Luisa Gascón-Castillo Aurora González-Estrada Demetrio González Carmen Gómez-González Rocío González-León Carmen Grande-Cabrerizo Sonia Gutiérrez Carlos Hernández-Quiles Inmaculada Concepción Herrera-Melero Marta Herrero-Romero Luis Jara Carlos Jiménez-Juan Silvia Jiménez-Jorge Mercedes Jiménez-Sánchez Julia Lanseros-Tenllado Carmina López Isabel López Álvaro López-Barrios Luis F.López-Cortés Rafael Luque-Márquez Daniel Macías-García Guillermo Martín-Gutiérrez Luis Martín-Villén JoséMolina Aurora Morillo María Dolores Navarro-Amuedo Dolores Nieto-Martín Francisco Ortega María Paniagua-García Amelia Peña-Rodríguez Esther Pérez Manuel Poyato Julia Praena-Segovia Rafaela Ríos Cristina Roca-Oporto Jesús F.Rodríguez María Jesús Rodríguez-Hernández Santiago Rodríguez-Suárez Ángel Rodríguez-Villodres Nieves Romero-Rodríguez Ricardo Ruiz Zida Ruiz de Azua Celia Salamanca Sonia Sánchez Víctor Manuel Sánchez-Montagut César Sotomayor Alejandro Suárez Benjumea Javier Toral | 2021 | Cellular & Molecular Immunology2021，18，9： | 2 |
