ABSTRACT
Resumen Una de las dificultades encontradas es la correcta identificación de insectos asociados a la descomposición cadavérica, por la cual ha llevado a buscar y generar nuevas herramientas en biología molecular que facilitan la determinación de especímenes para la estimación del Intervalo Post-Mortem de una forma efectiva y certera a partir de estadios inmaduros; la colecta y taxonomía morfológica de Dípteros se realizaron en primera instancia y posteriormente se utilizó el sistema de Códigos de Barras (COI Barcode) para la identificación molecular de insectos problema por medio del gen mitocondrial COI en cualquier fase del ciclo biológico. Identificando tres especies de adultos con una probabilidad de correspondencia del 100%; los especímenes: Sarconesia versicolor de la Familia Calliphoridae y Fannia sp., no fueron hallados en las bases de datos mundiales del GenBank y del Boldsystems, siendo necesario su actualización realizando patrones de sucesión cronológica de fauna cadavérica en diferentes zonas geográficas, cuya práctica se aplicaría en las investigaciones criminales.
Abstract One of the difficulties encountered is the correct identification of insects associated with cadaveric decomposition, which has led to the search and generation of new tools in molecular biology that facilitate the determination of specificities for the modification of the Post-Mortem Interval in an effective and accurate from immature stages; the collection and morphological taxonomy of Diptera were made in the first instance and then the Bar Code System (COI Barcode) was used for the molecular identification of problem insects by means of the mitochondrial COI gene in any phase of the biological cycle. Identifying three species of adults with a probability of 100% correspondence; the specimens: Sarconesia versicolor of the Calliphoridae Family and Fannia sp., were not found in the world databases of the GenBank and the Boldsystems, being necessary to update them by chronological succession patterns of cadaveric fauna in different geographical areas, whose practice would be applied in criminal investigations.

Abstract Tinea incognito resulting from corticosteroid abuse is becoming very common in the tropics. Its diagnosis is tricky owing to its confusing morphology, as well as practical and technical issues associated with mycological tests. Dermoscopy has now evolved as a novel diagnostic tool for diagnosing tinea incognito in such challenging situations, since the typical hair changes such as Morse-code hairs, deformable hairs, translucent hairs, comma and cork screw hairs, and perifollicular scaling may be seen despite steroid use, irrespective of mycological results.

Bar-code (tag) microarrays of yeast gene-deletion collections facilitate the systematic identification of genes required for growth in any condition of interest. Anti-sense strands of amplified bar-codes hybridize with ~10,000 (5,000 each for up- and down-tags) different kinds of sense-strand probes on an array. In this study, we optimized the hybridization processes of an array for fission yeast. Compared to the first version of the array (11 µm, 100K) consisting of three sectors with probe pairs (perfect match and mismatch), the second version (11 µm, 48K) could represent ~10,000 up-/down-tags in quadruplicate along with 1,508 negative controls in quadruplicate and a single set of 1,000 unique negative controls at random dispersed positions without mismatch pairs. For PCR, the optimal annealing temperature (maximizing yield and minimizing extra bands) was 58℃ for both tags. Intriguingly, up-tags required 3× higher amounts of blocking oligonucleotides than down-tags. A 1:1 mix ratio between up- and down-tags was satisfactory. A lower temperature (25℃) was optimal for cultivation instead of a normal temperature (30℃) because of extra temperature-sensitive mutants in a subset of the deletion library. Activation of frozen pooled cells for >1 day showed better resolution of intensity than no activation. A tag intensity analysis showed that tag(s) of 4,316 of the 4,526 strains tested were represented at least once; 3,706 strains were represented by both tags, 4,072 strains by up-tags only, and 3,950 strains by down-tags only. The results indicate that this microarray will be a powerful analytical platform for elucidating currently unknown gene functions.

Objective: To evaluate the use of ITS2 sequences as DNA barcode to identify the Zingiberaceae medicinal plants from E'mei area. Method: The genomic DNAs were extracted from 43 Zingiberaceae medicinal plant samples from Sichuan E'mei area. The ITS2 sequences of these samples were amplified and bidirectionally sequenced by PCR. 40 ITS2 sequences were downloaded from the GenBank,and then the interspecific and intraspecific genetic distances were calculated and analyzed by using MEGA 6.0 to construct Neighbor-joining (NJ) tree; TAXON DNA software was also used to analyze intraspecific and interspecific variations and barcoding gaps. The differences in secondary structure of the ITS2 sequences were predicted and compared. Result: The minimum interspecific distance in Zingiberaceae samples was greater than the maximum intra specific distance,with obvious barcoding gap. The NJ tree showed that the samples were clustered into five different branches,Alpinia,Curcuma,Globba,Hedychium,and Zingiber respectively,and further cluster into sub-branches. Significant differences were also present in the secondary structures of ITS2 between different samples. Conclusion: ITS2 sequences as DNA barcode can be used to conduct accurate and rapid identification of the Zingiberaceae plants and clearly figure out the phylogenetic relationship among them,providing guidance for the study of the distribution of medicinal plants of this genus,as well as theoretical basis for the quality control,medication safety and rational development of Zingiberaceae medicinal plants in E'mei area.
