The photoreceptor layer of the human retina has several characteristics that are unique. Their energy requirements are the highest in the organism;in proportion, rods and cones require 10-fold the energy consumed by the cerebral cortex, 6-fold more than the cardiac muscle, and 3-fold more than the renal cortex. Astonishingly, the photoreceptor layer has no blood vessels at all. So, where is the energy to this tissue coming from? In this article we’ll describe the hitherto unknown explanation.

Objectives: The purpose of this study is to analyse the practical implementation of regional and na-tional policies through the Protocol of Care of Children and Adolescents in School (2010) in Extremadura Region (Spain), and to compare its contents with the international standards of diabetes care at school defined by American Diabetes Association and International Diabetes Federation. The measures not only affect the security and diabetes care, but also inclusion and the right to health. Methods: A documental comparative analysis between the local and international standards about diabetes care in school setting is carried out. This analysis is framed in a larger project focused on the study of health promoting school and diabetes education, in which perceptions of children and adolescents with diabetes, their parents and school staff were studied. Results: The Protocol of Care of Children and Adolescents in School (2010) contains some international recommendations about the care of T1DM at school, but in other cases the measures are non-specific. The distribution of responsibilities for care at school is unclear and no monitoring and evaluation indicators are defined. Some elements are identified to be implemented in the tool to favour the security, management of T1DM care and wellbeing. In general, these elements refer to school plan for diabetes care, school organization and teachers, and school community training. Conclusion: It is required to develop specific policies and decisive action to ensure the right to health of children with diabetes and the full application of international standards for diabetes care at school.

Both dyskeratosis congenita (DC) and Hoyeraal-Hreidarsson Syndrome (HHS) are rare inherited bone marrow failure conditions. HHS is considered to be a variant of DC in which neurological deficits and immunodeficiencies are also present. We describe a very interesting familial cluster where an invariant point mutation of DKC1 located in the exon 11 is observed in the carrier mother and in two decedent males. The older child developed the classical phenotype of HHS at a very early age. The second affected child remains poorly symptomatic, with only mild haematological changes. Telomere shortening, with different severity, is also present in both cases. This paper discusses the clinical spectrum of inherited BM failure syndromes from the perspective different clinical presentation within a family with a DKC1 mutation.

This work assessed the relationship between synoptic circulation patterns, meteorological conditions and sulfate levels in rainwater in Orizaba Valley, Veracruz, Mexico during 2015. Samples were collected by using an automatic deposition sampler considering three climatic periods: Cold fronts or Nortes, Dry and Rainy seasons. Sulfate in rainwater was determined by turbidimetry (NMX-AA-SCFI-074-1981). A backward trajectory model (HYSPLIT) was used to characterize the potential source regions and transport pathways for air parcels arriving to Orizaba Valley;trajectories extended five days during 2015 were calculated. Mean concentrations of sulfate were 105.33, 37.5, and 52.5 μEq·l-1, for Cold Fronts, Dry and Rainy seasons, respectively. An evident dilution pattern was observed with lower concentration levels when rainfall increased. Mean values for sulfate concentration exceeded the background hemispheric value reported by Galloway et al. (1982) for remote sites (10 μEq·l-1), exceeding almost 10, 3.7 and 5.2 times, during the Nortes, Rainy and Dry seasons, respectively. From the obtained results, it was concluded that the high sulfate levels in the rainwater measured in Orizaba Valley had their origin in different upwind regional sources as a result of long-range transport during Rainy and Nortes seasons.

The aim of the present paper was to analyze the influence of sampling and storage procedures on nitrite con- centration values in the saliva of healthy persons. The samples were obtained and stored under varied condi- tions, and processed using the Griess method. Results: when the salivary nitrite concentration was measured immediately after collection a significant dependence on the collection time was observed. A mean value of 94 μmol/L (range 3 - 625) was obtained at 8:30 am. This value decreased significantly with time (p marked constancy independent of the sampling day. According to our results, by controlling pre-analytical parameters, principally sampling and storage procedures, reproducibility is improved.

Breast cancer affects one in eight women around the world. Seventy five percent of these patients have tumors that are estrogen receptor positive and as a consequence receive endocrine therapy. However,about one third eventually develop resistance and cancer reappears. In the last decade our vision of cancer has evolved to consider it more of a tissuerelated disease than a cell-centered one. This editorial argues that we are only starting to understand the role the tumor microenvironment plays in therapy resistance in breast cancer. The development of new therapeutic strategies that target the microenvironment will come when we clearly understand this extremely complicated scenario. As such,and as a scientific community,we have extremely challenging work ahead. We share our views regarding these matters.
