La relación entre el crimen y ciclo económico en México: un enfoque espacial

Ricardo Masahiro Solis Ichien (2021, [Tesis de maestría])

En este trabajo se analiza la influencia del ciclo económico sobre los niveles de crimen en México desde el marco conceptual de la teoría de Cantor y Land (1985), los cuales distinguen el efecto de oportunidad y motivación criminal. Se presenta el análisis para el caso mexicano y se evalúa empíricamente el modelo de Cantor y Land para las 32 entidades federativas con datos trimestrales del 2010 a 2019. Utilizando un modelo econométrico que incorpora la interacción espacial en la tasa de crímenes y en el término de error, así como su rezago temporal, al que se le denomina como modelo espacial autorregresivo con errores autorregresivos de orden 1 (SARAR (1,1)) dinámico, se evalúa el modelo para siete tipos de crímenes: homicidios dolosos, secuestros, extorsiones, robo a negocios, robo a casa-habitación, robo de vehículo y robo a transeúnte. Los resultados muestran que se verifica la teoría de Cantor y Land (1985) para cuatro de los siete tipos de delitos. Los robos analizados se caracterizan como robos de necesidad y robos de especialización. Se encuentra evidencia del comportamiento espacial de la actividad criminal donde algunos delitos tienen un efecto regional y otros se concentran.

Effect of photoperiod and temperature on the biochemical composition in wild broodstock of sardine cabrilla, Mycteroperca rosacea (Streets, 1877)

JOSE ANTONIO ESTRADA GODINEZ MINERVA CONCEPCION MALDONADO GARCIA VICENTE GRACIA LOPEZ Rene Rebollar MILTON ALEJANDRO SPANOPOULOS ZARCO (2014, [Artículo])

"Se estimó el factor de condición (K), el índice gonadosomático (IGS), hepatosomático (IHS) y de grasa visceral (IGV), así como la composición bioquímica en diferentes tejidos de reproductores silvestres de cabrilla sardinera, Mycteroperca rosacea, para evaluarlos a lo largo de un ciclo reproductivo y ver la relación que presentan los cambios con respecto a la temperatura del agua y fotoperiodo de la zona de muestreo. Se capturaron 187 reproductores, 146 hembras y 41 machos en el golfo de California, México. Se observaron diferencias significativas (P < 0,005) en los IGS, IHS e IGV; en el caso de K no se encontraron diferencias. También, se observaron variaciones significativas (P < 0,05) en la mayoría de los parámetros bioquímicos, encontrándose los valores más altos durante la etapa de desove, mientras que los más bajos durante la etapa de reposo. Todos los índices estimados y los parámetros bioquímicos determinados, se correlacionaron significativamente (P < 0,05) con el fotoperiodo, mientras que solo se encontraron correlaciones significativas (P < 0,05) entre el IGS e IGV con respecto a la temperatura del agua."

"Condition factor (K), gonadosomatic index, (IGS), hepatosomatic index (IHS) and fat visceral index (IGV) were estimated and the biochemical composition in different tissues of wild leopard grouper broodstock was determinate too, in order to evaluate them along a reproductive cycle and see the relationship of these changes with respect to the water temperature and photoperiod in the sampling area. 187 brooders were caught, 146 females and 41 males in the Gulf of California, Mexico. Significant differences (P < 0.005) in the IGS, IHS and IGV but not for K were observed. Significant changes (P < 0.05) were also observed in most of the biochemical parameters, being the highest value during the spawning stage, whereas the lowest occurred during the resting stage. Significant correlations (P < 0.05) between all estimated indices and biochemical parameters were observed, while only significant correlations (P < 0.05) between the IGS and IGV with respect to water temperature."

ELIANA VALENCIA LOZANO LISSET HERRERA ISIDRON Osiel Salvador Recoder-Meléndez Aarón Barraza Celis JOSE LUIS CABRERA PONCE (2022, [Artículo])

"Potato microtuber (MT) development through in vitro techniques are ideal propagules for producing high quality potato plants. MT formation is influenced by several factors, i.e., photoperiod, sucrose, hormones, and osmotic stress. We have previously developed a protocol of MT induction in medium with sucrose (8% w/v), gelrite (6g/L), and 2iP as cytokinin under darkness. To understand the molecular mechanisms involved, we performed a transcriptome-wide analysis. Here we show that 1715 up- and 1624 down-regulated genes were involved in this biological process. Through the protein–protein interaction (PPI) network analyses performed in the STRING database (v11.5), we found 299 genes tightly associated in 14 clusters. Two major clusters of up-regulated proteins fundamental for life growth and development were found: 29 ribosomal proteins (RPs) interacting with 6 PEBP family members and 117 cell cycle (CC) proteins. The PPI network of up-regulated transcription factors (TFs) revealed that at least six TFs–MYB43, TSF, bZIP27, bZIP43, HAT4 and WOX9–may be involved during MTs development. The PPI network of down-regulated genes revealed a cluster of 83 proteins involved in light and photosynthesis, 110 in response to hormone, 74 in hormone mediate signaling pathway and 22 related to aging."

Variability of Microcirculation Detected by Blood Pulsation Imaging

Alexei Kamshilin (2013, [Artículo])

The non-invasive assessment of blood flow is invaluable for the diagnostic and monitoring treatment of numerous vascular and neurological diseases. We developed a non-invasive and non-contact method of blood pulsation imaging capable of visualizing and monitoring of the two-dimensional distribution of two key parameters of peripheral blood flow: the blood pulsation amplitude and blood pulsation phase. The method is based on the photoplethysmographic imaging in the reflection mode. In contrast with previous imaging systems we use new algorithm for data processing which allows two dimensional mapping of blood pulsations in large object's areas after every cardiac cycle. In our study we carried out the occlusion test of the arm and found (i) the extensive variability of 2D-distribution of blood pulsation amplitude from one cardiac cycle to another, and (ii) existence of the adjacent spots to which the blood is asynchronously supplied. These observations show that the method can be used for studying of the multicomponent regulation of peripheral blood circulation. The proposed technique is technologically simple and cost-effective, which makes it applicable for monitoring the peripheral microcirculation in clinical settings for example, in diagnostics or testing the efficiency of new medicines. © 2013 Kamshilin et al.

Whole-genome comparison between reference sequences and oyster Vibrio vulnificus C-genotype strains

CARLOS ABRAHAM GUERRERO RUIZ (2019, [Artículo])

Whole-genome sequences of Vibrio vulnificus clinical genotype (C-genotype) from the CICESE Culture Collection, isolated from oysters, were compared with reference sequences of CMCP6 and YJ016 V. vulnificus C-genotype strains of clinical origin. The RAST web server estimated the whole genome to be ~4.8 Mb in CICESE strain 316 and ~4.7 Mb in CICESE strain 325. No plasmids were detected in the CICESE strains. Based on a phylogenetic tree that was constructed with the whole-genome results, we observed high similarity between the reference sequences and oyster C-genotype isolates and a sharp contrast with environmental genotype (E-genotype) reference sequences, indicating that the differences between the C- and E-genotypes do not necessarily correspond to their isolation origin. The CICESE strains share 3488 genes (63.2%) with the YJ016 strain and 3500 genes (63.9%) with the CMCP6 strain. A total of 237 pathogenicity associated genes were selected from reference clinical strains, where—92 genes were from CMCP6, 126 genes from YJ016, and 19 from MO6-24/ O; the presence or absence of these genes was recorded for the CICESE strains. Of the 92 genes that were selected for CMCP6, 67 were present in both CICESE strains, as were as 86 of the 126 YJ016 genes and 13 of the 19 MO6-24/O genes. The detection of elements that are related to virulence in CICESE strains—such as the RTX gene cluster, vvhA and vvpE, the type IV pili cluster, the XII genomic island, and the viuB genes, suggests that environmental isolates with the C-genotype, have significant potential for infection. © 2019 Guerrero et al.

Integrative taxonomy and molecular phylogeny of genus Aplysina (Demospongiae: Verongida) from Mexican Pacific

José Antonio Cruz-Barraza (2012, [Artículo])

Integrative taxonomy provides a major approximation to species delimitation based on integration of different perspectives (e.g. morphology, biochemistry and DNA sequences). The aim of this study was to assess the relationships and boundaries among Eastern Pacific Aplysina species using morphological, biochemical and molecular data. For this, a collection of sponges of the genus Aplysina from the Mexican Pacific was studied on the basis of their morphological, chemical (chitin composition), and molecular markers (mitochondrial COI and nuclear ribosomal rDNA: ITS1-5.8-ITS2). Three morphological species were identified, two of which are new to science. A. clathrata sp. nov. is a yellow to yellow-reddish or -brownish sponge, characterized by external clathrate-like morphology; A. revillagigedi sp. nov. is a lemon yellow to green, cushion-shaped sometimes lobate sponge, characterized by conspicuous oscules, which are slightly elevated and usually linearly distributed on rims; and A. gerardogreeni a known species distributed along the Mexican Pacific coast. Chitin was identified as the main structural component within skeletons of the three species using FTIR, confirming that it is shared among Verongida sponges. Morphological differences were confirmed by DNA sequences from nuclear ITS1-5.8-ITS2. Mitochondrial COI sequences showed extremely low but diagnostic variability for Aplysina revillagigedi sp. nov., thus our results corroborate that COI has limited power for DNA-barcoding of sponges and should be complemented with other markers (e.g. rDNA). Phylogenetic analyses of Aplysina sequences from the Eastern Pacific and Caribbean, resolved two allopatric and reciprocally monophyletic groups for each region. Eastern Pacific species were grouped in general accordance with the taxonomic hypothesis based on morphological characters. An identification key of Eastern Pacific Aplysina species is presented. Our results constitute one of the first approximations to integrative taxonomy, phylogeny and evolutionary biogeography of Eastern Pacific marine sponges; an approach that will significantly contribute to our better understanding of their diversity and evolutionary history. © 2012 Cruz et al.

Functional characterization and cellular dynamics of the CDC-42 - RAC - CDC-24 module in neurospora crassa

CYNTHIA LIZZETH ARAUJO PALOMARES (2011, [Artículo])

Rho-type GTPases are key regulators that control eukaryotic cell polarity, but their role in fungal morphogenesis is only beginning to emerge. In this study, we investigate the role of the CDC-42 - RAC - CDC-24 module in Neurospora crassa. rac and cdc-42 deletion mutants are viable, but generate highly compact colonies with severe morphological defects. Double mutants carrying conditional and loss of function alleles of rac and cdc-42 are lethal, indicating that both GTPases share at least one common essential function. The defects of the GTPase mutants are phenocopied by deletion and conditional alleles of the guanine exchange factor (GEF) cdc-24, and in vitro GDP-GTP exchange assays identify CDC-24 as specific GEF for both CDC-42 and RAC. In vivo confocal microscopy shows that this module is organized as membrane-associated cap that covers the hyphal apex. However, the specific localization patterns of the three proteins are distinct, indicating different functions of RAC and CDC-42 within the hyphal tip. CDC-42 localized as confined apical membrane-associated crescent, while RAC labeled a membrane-associated ring excluding the region labeled by CDC42. The GEF CDC-24 occupied a strategic position, localizing as broad apical membrane-associated crescent and in the apical cytosol excluding the Spitzenkörper. RAC and CDC-42 also display distinct localization patterns during branch initiation and germ tube formation, with CDC-42 accumulating at the plasma membrane before RAC. Together with the distinct cellular defects of rac and cdc-42 mutants, these localizations suggest that CDC-42 is more important for polarity establishment, while the primary function of RAC may be maintaining polarity. In summary, this study identifies CDC-24 as essential regulator for RAC and CDC-42 that have common and distinct functions during polarity establishment and maintenance of cell polarity in N. crassa. © 2011 Araujo-Palomares et al.
