Aims and objectives: To test an automated telephone service as a follow-up and support strategy for self-care in a population of adult Mexican patients with type 2 diabetes. Methods: The design was a two-group comparative design, with pre and post-intervention measurements. Patients were assigned into intervention (n = 31), or comparison (n = 33) groups. Over 12 weeks, each participant in the intervention group received automated phone calls with instructions to facilitate accomplishment of the treatment, and self-care activities. Two focus groups helped to appreciate patients’ follow-up experience. Randomized grouping was performed by selecting numbers from an urn;the final sample comprised 31 (48%) patients in the intervention group, and 33 (52%) in the comparison group;these procedures were performed by the case nurse management. The study was approved by the Ethics Committee of the Autonomous University of Nuevo Leon and the University of Michigan;all of the participants signed informed consent. Results: Of the 372 programmed phone calls made to the participants, 234 were completed, representing a 62.9% response rate. Phone calls may be associated to a 0.82% decrease in the HbA1c values and to lower depression scores. HbA1c measurements decreased 0.82% (M = 7.41 - 6.69;t = 25;4.11;p = ?0.001) from the baseline values over the 12-week study in the intervention group and 0.49% (M = 7.24 - 6.75;t = 26;2.11;p = 0.044) in the comparison group. Variables related to medication intake did not exhibit differences between the baseline and second measurements, except with respect to the scale of depression.

Percoll Gradient Optimization for Blood CD133+ Stem Cell Recovery

引用

Stem Cell Discovery 2014年第3期4卷 61-66页

作者： rosa María López-Franco Jorge E. Moreno-Cuevas María Teresa González-garza Servicio de Terapia Celular School of Medicine CITES Tecnológico de Monterrey Monterrey México

Circulating CD133+ stem cells from the peripheral blood have been shown to be able to differentiate into numerous cell lineages. However, adults have only a small number of these circulating stem cells. The aim of the present study was to assess a new isolation and enrichment technique for CD133+ stem cells from peripheral blood with the use of Percoll density gradients. Our results demonstrated the presence of two large mononuclear bands when whole blood was centrifuged with 48% and 50% Percoll concentrations. Flow cytometric analysis (FACS) revealed a major CD133+ enrichment at the 48% Percoll concentration in one of the two bands. Further culture of these cells resulted in the formation of multiple colony-forming units. Our results suggest an advantage from using a simple Percoll gradient for successful CD133+ cell recovery, which could aid in differentiation and transplantation protocols.

The endemic silverside fish C. humboldtianum is of great ichtyologycal, economical and cultural relevance in central Mexico and it has been suggested that it is among a group of other “peces blancos”, the most ancestral species. Here we characterized a set of 26 microsatellite loci from the species in order to further assess population and phylogeographic issues that aid in evaluating their highly impacted populations. From 58 primer pairs tested on specimens from Villa Victoria dam (Rio Balsas Basin), 26 loci positively amplified on the species and cross-primed on specimens of the closely related and threatened Poblana alchichica, C. promelas and C. riojai. Loci resolved medium and high genetic variation (mean NA = 14.3, SD = 9.38;mean HO & HE = 0.47, SD = 0.32 and 0.58, SD = 0.32, respectively) and it is expected that these polymorphic loci are also useful in studing threatened atherinopsid species.

Background: Brain metastases from papillary thyroid carcinoma are infrequent occurring in 0.15% to 1.3% of patients, and they are generally accompanied by synchronous metastases in other sites and in isolation are even less frequent;the information about their management is limited and it has been based mainly on retrospective studies, experiences, case reports, and management guidelines of brain metastasis of other cancers. Aim: We report this case with the objective of describing how unpredictable the behavior of thyroid cancer can be despite being classified as low risk of recurrence. Case Presentation: A female patient with a diagnosis of papillary thyroid carcinoma classified as low risk who after more than a year of surveillance and without alterations in laboratory and imaging studies, developed a single brain metastasis susceptible to treatment with radioactive iodine (RAI) therapy. Conclusion: This case emphasizes the importance of a close follow-up of patients and not to minimize any symptom, no matter how simple it may seem, since cancer has no rules in its evolution.

The chemistry of rainwater has been subject to numerous investigations during the last two decades due to the increase of environmental problems caused by the acid deposition. The present study focuses on one aspect of air pollution, the chemical composition of wet deposition of an industrial zone. The sampling period was from March to December 2009. The station was located on the roof of the Chemistry School at the University of Nuevo León, an area in the north of Monterrey where the majority of pollution is generated. Twenty-five wet precipitation samples were collected with an automatic sampler and analyzed for pH, ions (, , Cl-, Ca2+, Mg2+, Na+, K+) and conductivity. The results show that the average pH is higher than 5.6;the characteristics of the rainwater studied are of alkaline nature due to the values of pH found;there is an evident anthropogenic source contributing to the alkaline of rain water. In order to find possible association between ions and consequently the possible sources of pollutants correlation study was applied using the program SPSS v.12. Good correlations were found between ions and along with Ca2+ and Mg2+. The local extraction industry and surrounding aerosols might be causing of alkaline rain which may be due to the neutralization effect of particulate matter. This study represents a continuation of the studies of rainwater chemistry in the Northeast of Mexico.

作者： rosa María Cerón Bretón Julia Griselda Cerón Bretón Claudia Alejandra Aguilar Ucán Evangelina Ramírez Lara José Abraham Ortínez álvarez Carlos Montalvo Romero Carmen Guadalupe Carballo Pat Chemistry Department Autonomous University of Nuevo Leon San Nicolás de los Garza Mexico National Center for Training and Environmental Research National Institute of Ecology Mexico City Mexico Research Center on Environmental Sciences Autonomous University of Carmen Botanical Garden Carmen City Mexico

Wet deposition was collected in Mexico City (MC), Metropolitan Area of Monterrey (MAM) and El Chico National Park (ECNP), during 2009 and 2010. pH, conductivity, Cl-, , Na+, K+, Ca2+ and Mg2+ were determined. In MC, sulphate levels were greater than nitrate levels, and NH4 had mixed sources (vehicular emissions and agriculture activities). MAM had markedly alkaline atmospheric deposition, Na+ and Cl-levels were unexpectedly high, especially during hurricane “Alex”. Low pH values were found in ECNP and nitrate concentrations were high, suggesting the influence of a local source (forest fires). Deposition fluxes (***-1yr-1) for N-NO3, N-NH4 and S-SO4 were 1.36, 2.74 and 4.84 for MAM;7.27, 0.57 and 4.32 for ECNP;and 5.97, 4.96 and 6.78 for MC, respectively. Nitrogen deposition fluxes in ECNP were high considering that this site is a natural reserve.

Introduction: The World Health Organization establishes that 80% of the world’s population uses traditional medicine for their primary care, because they contain compounds responsible for their properties. Objective: To evaluate the antifungal effect of the essential oil of Citrus paradisi against C. albicans and the cytotoxic effect in three cell lines in vitro. Methods: The phytochemical characterization of the oil was carried out by chemical methods and Gas chromatography (GC-MS) and the antifungal effect against C. albicans (ATCC 90029) was evaluated by the Kirby-Bauer method, which evaluated concentrations of 0.75 - 20 μg/mL and compared with nystatin 100,000 Ul/mL as a positive control. The percentage of the relative inhibitory effect was calculated. The minimum inhibitory concentration (MIC) was determined at 24 hours. Moreover, the cytotoxic effect on C. albicans and cell lines was determined by the colorimetric MTT tetrazolium assay. Finally, the antifungal effect against Candida strains isolated from clinical samples was evaluated at a concentration of 20 μg/mL. Results: The essential oil showed an antifungal effect with a percentage of inhibition of 123%. The MIC was 2.5 μg/mL, and the cytotoxicity index was 5.44 μg/mL for C. albicans. The IC50 values were 21.060, 9.482 and 4.176 μg/mL for Vero E6, J774A.1 and MDBK cells respectively. Conclusion: These results show the use of C. paradisi essential oil as an alternative treatment in oral antifungal therapy, it is beneficial due to its antifungal effect and its low toxicity on cell cultures.
