Metamateriales nanoestructurados: avances en el cálculo de sus propiedades ópticas
Authors: Meza Ulises R. , Mendoza Bernardo S. , Mochán W. L. 
Published: November 2019

Este artículo tiene como objetivo presentar el trabajo realizado en los últimos años en el campo de metamateriales nanoestructurados. Se muestran principalmente los trabajos realizados en el Centro de Investigaciones en Óptica A. C. en conjunto con el Instituto de Física de la UNAM. Estos trabajos se han centrado en el desarrollo de nuevos modelos teóricos que permitan explicar las propiedades ópticas de sistemas nanoestructurados. Además, dichos modelos se han implementado dentro de paquetes computacionales de alto rendimiento, lo cual ha posibilitado la realización de cálculos numéricos precisos, mismos que permiten conocer las cantidades físicas con las que se puede caracterizar un material; en este caso, metamateriales nanoestructurados. Mayoritariamente, dichos cálculos numéricos se han centrado en el cómputo de la función dieléctrica y la susceptibilidad no lineal, siendo de suma importancia poder predecir su valor de forma precisa por ser dos cantidades fundamentales en el entendimiento de la interacción de la luz con la materia. Además de este desarrollo teórico-numérico, se muestran algunos resultados importantes obtenidos a lo largo de este tiempo, donde se puede observar la versatilidad y flexibilidad de los cálculos así como la importancia de contar con dichas metodologías en la predicción, descripción y diseño de materiales “a la medida” de las necesidades. Por último, se presentan las perspectivas a futuro de esta investigación, así como algunos de los retos más importantes al respecto.
Las agendas estatales de innovación en México: ¿gobernanza científica discrecional o de mercado?
Authors: Anzaldo Mónica 
Published: November 2019

El establecimiento de prioridades de investigación e innovación es una preocupación permanente en la gobernanza de la ciencia y la tecnología, debido a que permea la definición de los objetos de estudio, la asignación de recursos por parte del Estado y la apropiación social de los resultados. Este artículo analiza las Agendas Estatales de Innovación en México, un programa impulsado por el gobierno mexicano para definir prioridades de innovación en la escala estatal. Analíticamente, el estudio se conduce a partir de la tipología de modos de gobernanza de Hagendijk & Irwin (2006) con el objetivo de examinar en qué medida este instrumento muestra avances en la democratización de la gobernanza de la ciencia en el país. Metodológicamente, se sistematizó la información de las agendas y se realizaron entrevistas semiestructuradas a actores clave. Se concluye que las agendas coinciden con los modos de gobernanza de mercado y discrecional, pues los temas prioritarios representan los intereses de la élite empresarial y gobernante del país. Se plantea como hipótesis que en las agendas están presentes varios elementos que apuntan la orientación de la ciencia hacia una lógica de mercado alineada con el neoextractivismo, que se expande en la región latinoamericana.

ABSTAKKesehatan dan keselamatan adalah aspek penting dalam kehidupan manusia, baik dalam bekerja ataupun dalam kehidupan sehari-hari. Hal tersebut memberikan dampak negatif bila tidak diperhatikan karena kesehatan dan kseselamatan memberikan rasa aman dan nyaman pada kita pada setiap kegiatan. Setiap pekerjaan atau tindakan selalu mempunyai risiko sekecil apapun, apalagi bila pekerjaan yang memang benar-benar mempunyai risiko yang tinggi seperti bekerja di bidang manufaktur atau di bidang migas. Kesehatan dan keselamatan di rumah tinggal pun tak kalah pentingnya, seorang ibu rumah tangga ataupun pembantu rumah tangga mempunyai risiko kegiatan yang tinggi seperti kegiatan di dapur adanya tabung gas, api dari kompor yang menyala, minyak panas, alat rumah tangga bertenaga listrik, bahan kimia yang digunakan saat membersihkan kamar mandi, mencuci, obat anti serangga dan lainnya. Karena prinsipnya dalam K3 yang harus diamankan terlebih dahulu adalah lingkungannya (safe condition) barulah dilakukan pengamanan dalam tindakan (safe act). Kegiatan ini disajikan dalam bentuk workshop, praktik, diskusi, tanya jawab dan tugas mandiri. Hasil evaluasi kegiatan pada awal masih peserta masih sangat awam dengan istilah K3 atau safety house, namun setelah selesai kegiatan ini peserta dapat memahami dan menunjukan sikap safety di rumah dan lingkungan sekitar. Seperti halnya mereka dapat mengidentifikasi berbagai macam bahaya dan mulai menata ulang kembali rumah tinggal mereka.ABSTRACTHealth and safety are important aspects of human life, both at work and in everyday life. This has a negative impact if it is not considered because health and safety provide us with a sense of security and comfort in every activity. Every job or action always has the slightest risk, especially if the work really does have a high risk such as working in manufacturing or in the oil and gas sector. Health and safety at home is equally important, a housewife or housemaid has a high risk of activities such as activities in the kitchen with gas cylinders, fire from burning stoves, hot oil, electric-powered household appliances, chemicals that used when cleaning bathrooms, washing, insect repellent and others. Because the principle in K3 that must be secured first is the environment (safe condition), then safeguards are carried out. This activity is presented in the form of workshops, practices, discussions, question and answer and independent assignments. The results of the activity evaluation at the beginning were that participants were still very unfamiliar with the term K3 or safety house, but after completing this activity the participants could understand and show safety attitudes at home and the surrounding environment. Just as they can identify various kinds of hazards and start rearranging their homes.

Español. La especie Corema album se encuentra en el litoral oeste de la Península Ibérica, desde Camariñas (La Coruña) hasta Punta Camarinal (Cádiz), donde ha sufrido un considerable retroceso, como otros muchos taxones de distribución costera. A lo largo del área en la cual aparece se ha usado en ceremonias religiosas, al igual que se aprovechaban sus frutos comestibles, los cuales llegaron a ser un producto más en algunos mercados de ciudades gallegas y portuguesas. En cambio, no estaba constatado el uso de tal especie en la región andaluza, que es el principal objetivo de este trabajo. Por medio de encuestas a los habitantes de Barbate (Cádiz) se demuestra que los frutos de C. album se usaron y comercializaron en este pueblo hasta finales de los años cincuenta, cuando desbroces por parte de los gestores de la zona para favorecer las plantaciones de pino disminuyeron la producción de frutos de este arbusto en los años siguientes. De forma conjunta se produjo en la zona un alzamiento económico, que permitiría la aparición de puestos de trabajo con más beneficios que la venta de frutos de la camarina, lo cual hizo que su el uso de tal especie en la zona desapareciera hasta nuestros días.english. Corema album is an endemic species from the west coastline of the Iberian Peninsula, from Camariñas (La Coruña) to Punta Camarinal (Cádiz). This plant has suffered an intense deterioration in the last few decades. This bush has been used in some religious ceremonies along its natural distribution, and its fruit has been eaten in some towns in Galicia and Portugal. The key objective in this study is analyze whether this fruit was used or not in Andalucía, since this fact is not know yet. By interviewing the inhabitants of Barbate (Cádiz) we have been found that the fruit of Corema album were eaten and sold in this village until the end of the fifties, when consecutive cleanings of the vegetation against bushes joined with a better economic situation caused the end of this activity.
Current state of umbilical cord stem cells in humans

Published: November 2019

Abstract
The umbilical cord is an unlimited source of mesenchymal stem cells (MSC) and hematopoietic stem cells (HSC). MSC obtained from the umbilical cord can be differentiated into different types of mesodermal cells, e.g. chondrocytes, osteocytes, adipocytes, and myocytes. It is also worth mentioning that there are reports of MSC differentiation into endo and ectodermal cells. The immunosuppressive properties of MSCs can protect against graft versus host disease as well as prevent rejection after transplantation. Umbilical cord stem cells can be frozen and then stored in liquid nitrogen for many years. In this work, we focused on the use of preclinical and clinical umbilical cord stem cells in disease entities such as type I diabetes, chronic renal failure, and multiple sclerosis. Furthermore, the anti-cancer properties of Wharton’s jelly cells are described.

Abstract
Alterations in cells depend on their genetic material, its activation and translation of the products. The genes responsible for the cell cycle processes and apoptosis of porcine oviductal cells have been presented in our study. The processes occurring in the reproductive system of females are extremely complex and require in-depth knowledge. Thanks to in vitro studies on the fallopian tube epithelium cells, we can get closer to understanding the biochemical and morphological changes occurring in mammalian organisms. Our research was conducted on fallopian tubes obtained from commercially bred pigs and its aim was to assess the expression profile of genes responsible for the most important processes of cellular life. Cell cultures were carried out for 30 days, with the obtained cells subjected to molecular analysis. We have shown significant regulation of “cell death” and “cell cycle” genes, some of which are related to the reproductive system. The alterations in transcriptomic profile and mutual relations between the genes were analyzed and related to the literature findings. The knowledge gained could help in identifying new potential markers of the in vitro occurrence of processes described by the ontology groups of interest.

Authors: Hutchings Greg , Nawrocki Mariusz J. , Mozdziak Paul , Kempisty Bartosz 
Published: November 2019

Abstract
Cardiovascular disease (CVD) remains the most common cause of death worldwide. Unhealthy lifestyle choices promote an upward trend of primary risk factors for CVD. As a result, novel methods of treatment are required. The myocardium itself could serve as a source of treatment, via resident cardiac progenitor cells (CPC). A brief overview of current studies and findings related to the potential of differentiation of CPCs to form mature cardiomyocytes (CM) and thereby heal damaged myocardial tissue, as well as implications of these findings for further research areas and possible treatments, is offered. Also investigated is the possible role of CM cell reprogramming, cardiac fibroblasts and signalling molecules in treatment of CVD.

Published: November 2019

Abstract
Prevalence of neurodegenerative diseases, most of which are life threatening and incurable, is an increasing clinical problem. To date, studies have demonstrated a superior proliferation rate of dental pulp stem cells (DPSCs) compared to other mesenchymal stem cells in vitro. DPSCs has recently been recognized as a novel treatment strategy for neurodegenerative disease, due to their advanced potential for neurogenic differentiation. The oral cavity has been described as a promising source of dental pulp stem cells. DPSCs are widely used in regenerative dentistry holding alternative capacity for osteogenic differentiation and therefore new promises for tissue and whole tooth regeneration. Dental stem cell banking offers a plentiful source of stem cells representing great potential for cell reprogramming and thus cell therapy. Recently, the association of pulp stem cells with three – dimensional scaffold templates allows for building up naturally derived implants. This review introduces to unique properties of DPSCs and biological factors influencing mineralization, proliferation and differentiation of pulp stem cells. Latest research studies are compared in terms of effectiveness and limitations of techniques for the isolation of pulp stem cells, including the enzymatic digestion and the explant culture methods. Moreover, a short overview of most recent findings and clinical application of DPSCs is proffered including progress of current research and limitations still to be addressed in the nearest future. Finally, the article presents new advances in the area of regenerative dentistry and regenerative medicine, including three dimensional printing and three dimensional analysis, emerged to deepen studies under procedures to replace the non patient specific artificial implants.

Ovarian follicular cells - living in the shadow of stemness cellular competence
Authors: Moncrieff Lisa , Mozdziak Paul , Jeseta Michal , Machatkova Marie , Kranc Wiesława , Kempisty Bartosz 
Published: November 2019

Abstract
Granulosa cells (GCs) are a major component found in ovarian follicular fluid among oocytes, theca cells, and ovarian surface epithelial (OSE) cells. GCs are steroidogenic and have morphological functions that are important for the development of the follicular follicle. The follicle protects the developing female egg. GCs are also essential for the maturation of the female germ cell. Stem cell properties have been found in luteinised GCs and in vivo cultures have the potential to differentiate to become cells found outside of the ovary. Both three-dimensional (3D) culturing and mouse embryonic fibroblast (MEF) medium have been used to help improve the culturing lifespan of GCs so that their profound proliferation and differentiation capabilities can be studied. Small RNAs called MicroRNAs (miRNAs) are released from exosomes originating from GCs, and they are involved in transforming growth factor (TGF)-β signalling, follicle-stimulating hormone, hormone-related miRNAs, and apoptosis-related pathway. Finding the miRNAs involved in these pathways, and the mechanisms controlling GCs are important to treating conditions like polycystic ovary syndrome (PCOS), and creating new drug therapies. Besides GCs, ovarian stem cells (OSCs) were discovered in the OSE, and they are believed to be derived from very small embryonic stem cells (VSELs). Transplanting blood mononuclear cells, cell Hormone Therapy (cHT) with bone marrow stem cell supplement and increasing vitamin C levels are all therapies currently being researched into that involve GCs to combat the effects of aging and infertility.
