AIM To validate intracellular cytokine production functional assay as means of cell-mediated immunity monitoring of post-transplant patients with opportunistic infection(OI).METHODS Intracellular cytokine-producing CD4^+ and CD8^+ T-cell monitoring was carried out in 30 liver transplant(LTr) and 31 kidney transplant(KTr) recipients from 2010 to 2012. Patients were assessed in our department of Immunology at the Clinical University ‘Hospital Virgen de la Arrixaca-IMIB' in Murcia, Spain for one year following transplantation. FACS Canto Ⅱ flow cytometer was employed to quantify the intracellular production of IL-17, IFNγ and IL-10 cytokines on stimulated CD4^+CD69^+ and CD8^+CD69^+ T cells and BD FACS DIVA v.6 software was used to analysed the data. Statistical analysis was carried out using SPSS *** LTr with OI had significantly lower % of CD8^+CD69^+IFNγ^+T cells at 60(7.95 ± 0.77 vs 26.25 ± 2.09, P lantation. Higher % of CD4^+CD69^+IL-10^+ as well as CD4^+CD69^+IL-17^+ T cells were yet reported at 30(14.06 ± 1.65 vs 6.09 ± 0.53, P = 0.0007 and 4.23 ± 0.56 vs 0.81 ± 0.14, P = 0.005; respectively), 60(11.46 ± 1.42 vs 4.54 ± 0.91, P = 0.001 and 4.21 ± 0.59 vs 1.43 ± 0.42, P = 0.03; respectively) and 90 d(16.85 ± 1.60 vs 4.07 ± 0.63, P lantation as opposed to CD4^+CD69^+IL-10^+ and CD8^+CD69^+IL-10^+ T cells which percentages were higher at 30(25.21 ± 2.74 vs 8.54 ± 1.64, P < 0.001 and 22.37 ± 1.35 vs 17.18 ± 3.54, P = 0.032; respectively), 90(16.85 ± 1.60 vs 4.07 ± 0.63, P < 0.001 and 23.06 ± 2.89 vs 10.19 ± 1.98, P = 0.002) and 18

Effect of split applications of urea on protein size distribution, physical dough properties, and baking performance of five experimental bread wheat lines

引用

Agricultural Sciences 2011年第3期2卷 181-190页

作者： Alma rosa Islas-Rubio Karla Chávez-Quiroz Francisco Vásquez-lara Brenda Silva-Espinoza mar.a del Carmen Granados-Nevárez Humberto Gonzalez-Ríos Miguel Camacho-Casas departamento de Tecnología de Alimentos de Origen Vegetal Centro de Investigación en Alimentación y Desarrollo A.C.

Carretera a la Victoria Km 0.6 Hermosillo Sonora México. 83000

Five experimental bread wheat lines (BWL) were grown at the Yaqui Valley Experimental Station in Sonora, México during two consecutive growing cycles. The effect of five nitrogen fertilization (NF) treatments on protein size distribution (PSD), physical dough properties (PDP), and baking performance of the BWL was evaluated. Polymeric and monomeric proteins were evalu-ated by SE-HPLC. PDP were carried out by the National Mixograph and the TA-XT2 Texture Analyzer. Baking performance was evaluated using the straight dough method. Protein content (PC), main protein fractions (glutenins, gliadins, albumins-globulins), and mixograph development time (MDT) were significantly influenced by NF treatment and BWL but not by their interaction. On the other hand, PDP measured by the Kieffer rig, and baking performance were significantly influenced by the main factors (NF and BWL) and their interaction. The amount and timing of fertilizer applied to the BWL modified the PC, PSD, PDP, and bread loaf volume. PDP exhibited a larger variation in comparison to the PSD of glutenins. The split application of 150 kg of urea/ha (50-50-50) to all BWL showed a better loaf volume response than the same amount of urea applied at sowing (150-0-0). The application of 300 kg of urea/ha to all BWL, either at sowing or at three split applications of 100 kg of urea/ha each, resulted in higher flour unextractable polymeric protein (FUPP). On the other hand, the split application of 100-100-100 kg of urea/ha to three of the BWL represented the higher total unextractable polymeric protein (TUPP). Differences on PC and PSD were reflected on differences on PDP and bread loaf volume observed among the BWL.

Background: Nursing is considered a science in the making that recognizes the nursing process (NP) as the scientific and methodological tool to provide care. The NP is composed of five stages of which the assessment is the first and fundamental to identify the health problems of the people. This research aimed to evaluate a pedagogical didactic strategy that is based on situated constructivism, the Based-Problem Learning (BPL), in order to improve significant learning. Methods: Quantitative research with an explanatory scope, was transversal, and it was applied to 30 students of the first year of the nursing career at the Faculty of Higher Studies Iztacala, National Autonomous University of Mexico. The sample was chosen considering the inclusion criteria. Data were collected using a Likert-type instrument validated in a previous investigation. Results: The average value obtained from the Likert scale to evaluate the intervention was 103.4, the highest score was 135 and the lowest was 83, which reflects that it was evaluated as good and particularly good. The grade given to the teacher as an agent of the ZPD, was between agree and totally agree, the highest percentages scored at 93%, since it provoked challenge in their thinking, and favored interaction among classmates. Conclusions: The application of the in situ teaching strategy, BPL favored significant learning of the assessment stage, the students were able to carry out the assessment in the hospital, the experience contributed to generate significant learning when students face real scenarios, which showed the effectiveness of the method.

Background: To identify risk factors associated with pneumothorax and to determine the prognosis of cystic fibrosis patients following an episode of pneumothorax in the city of Madrid. Methods: Records of 17 patients (10 males;age 24.4 ± 17.5 years) and 32 controls, and a total of 44 pneumothorax episodes were studied. We have analyzed the characteristics of the pneumothorax, the microbiology, the lung function tests (LFT) and the prognosis of patients. Two controls with cystic fibrosis and without pneumothorax matched for sex and age were selected. Results: Eight male and three female patients with pneumothorax were older than 18 years. The mean age of the first pneumothorax episode was 18.3 years (±9.6). The group with pneumothorax had a mean body mass index of 19.2(±2.42 kg/m2) and in the control group it was 26.5 (±1.98 kg/m2). Pseudomonas aeruginosa was present in fourteen patients (82%) with pneumothorax and in eleven patients (34.4%) in the control group (p = 0.002). Pneumothorax predominantly occurred in the coldest seasons. There was a significant drop in both forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) after the pneumothorax. In the same way, FEV1 and FVC were greater in the control group. Six patients (35.4%) with pneumothorax and two patients in the control group have died (p de of pneumohorax. Patients with pneumothorax have worse LFT than patients without pneumothorax. Mortality is greater in patients with pneumothorax.

SARS-CoV-2 is a novel RNA coronavirus responsible of a deadly pandemic: the clinical illness COVID-19. With only one authorized drug for emergency use in critically ill patients: Remdesivir, there is not any other approved drug or vaccine yet with proven potential to overcome this infection. We exposed here many scientific evidences to support our novel idea that a macrolide, basically Clarithromycin, could be effective as a single agent for treatment and prophylaxis of COVID-19. Clarithromycin could change the history of this pandemic. It could reduce the costs of treatment and the potential adverse effects when combining more than one drug such as with Hydroxychloroquine. Clarithromycin treatment and prophylaxis as a single agent could be much more simple, safe and cheaper as giving Chloroquine or Hydroxychloroquine alone or in combination with Azithromycin as well as other therapeutic options.

Parasite Communities of the Pacific Mole Crab,Emerita rathbunae(Anomura:Hippidae),in Sandy Beaches from Guerrero and Michoacan,Mexico

引用

Open Journal of marine Science 2015年第4期5卷 468-476页

作者： Juan Violante-Gonzalez guadalupe Quiterio-Rendon Scott Monks Sergio García-Ibanez Griselda Pulido-Flores Agustín A.Rojas-Herrera Edvino larumbe-Moran Unidad Académica de Ecología marina Universidad Autónoma de GuerreroAcapulcoMéxico Centro de Investigaciones Biológicas Universidad Autónoma del Estado de HidalgoPachucaMéxico Centro de Estudios Tecnológicos del mar Lazaro CardenasMexico

The species composition and infection levels were determined for helminth parasites in the mole crab, Emerita rathbunae, collected from seven sandy beaches from Guerrero and Michoacán, México. A total of 494 crabs were collected between August and december of 2009. The number of crabs that were examined from each beach varied from 40 in Lázaro Cárdenas to 114 in El Revolcadero. The cephalothorax length varied significantly between the sampled beaches, from 32.9 ± 5.5 mm (Ixtapa) to 40.5 ±1.7 mm(las Trancas). Four species of larval parasites were identified: 1 metacercaria (Microphallus nicolli), 1 cystacanth (Profilicollis sp.), 1 cestode (Trypanorhyncha) and 1 nematode (Proleptus sp.). Infection levels (prevalence and mean abundance) varied significantly between beaches, due to possible differences in the availability of final or intermediate hosts in beaches visited by tourist and those beaches not visited by tourists, as well as the size of individual hosts. Helminth communities, at levels of component and infracommunity, were characterized by a low number of species (3 to 4) and a high dominance by the metacercaria of M. nicolli. The body size of the hosts was positively correlated with the number of parasites and species richness of helminths, indicating that larger crabs accumulate a higher number of parasites during the lifetime, and that they harbor a higher number of species of helminth than smaller crabs.

AIM: To study a cohort of consecutive patients under-going transcatheter aortic valve implantation (TAVI) and compare the outcomes of atrial fibrillation (AF) patients vs patients in sinus rhythm (SR). METHODS: All consecutive patients undergoing TAVI in our hospital were included. The AF group comprised patients in AF at the time of TAVI or with history of AF, and were compared with the SR group. Procedural, echocardiographic and follow-up variables were compared. Likewise, the CHA 2 DS 2-VASC stroke risk score and HAS-BLED bleeding risk score and antithrombotic treatment at discharge in AF patients were compared with that in SR patients. RESULTS: From a total of 34 patients undergoing TAVI, 17 (50%) were allocated to the AF group, of whom 15 (88%) were under chronic oral anticoagulation. Patients in the AF group were similar to those in the SR group except for a trend (P = 0.07) for a higher logistic EuroSCORE (28% vs 19%), and a higher prevalence of hypertension (82% vs 53%) and chronic renal failure (17% vs 0%). Risk of both stroke and bleeding was high in the AF group (mean CHA 2 DS 2-VASC 4.3, mean HAS-BLED 2.9). In the AF group, treatment at discharge included chronic oral anticoagulation in all except one case, and in association with an antiplatelet drug in 57% of patients. During a mean follow-up of 11 mo (maximum 32), there were only two strokes, none of them during the peri-procedural period: one in the AF group at 30 mo and one in the SR group at 3 mo. There were no statistical differences in procedural success, and clinical outcome (survival at 1 year 81% vs 74% in AF and SR groups, respectively, P = NS). CONCLUSION: Patients in AF undergoing TAVI show a trend to a higher surgical risk. However, in our cohort, patients in AF did not have a higher stroke rate compared to the SR group, and the prognosis was similar in both groups.
