Gender of authors in the Mexican Journal of Behavior Analysis: changes over time [GÉNERO DE LOS AUTORES DE LA REVISTA MEXICANA DE ANÁLISIS DE LA CONDUCTA: CAMBIOS A TRAVÉS DEL TIEMPO]

The Mexican Journal of Behavior Analysis was examined from 1975 to 2018 to determine the proportion of authorship by women and men. Data were compiled and assessed for the percentage of authorship, percentage of first-authored publications, percentage of publications with at least one woman, and percentage of publications with at least one man. From the journal’s inception to 2018, women and men accounted for 33% and 67% of authorship, respectively. The data suggest that women’s participation, based on percentages of total authorship, has increased across time. - Con el propósito de determinar la proporción de autores mujeres y hombres, se analizaron los artículos publicados en la Revista Mexicana de Análisis de la Conducta de 1975 a 2018.

Heliconia SCARLET: a mexican variety for cut flower and gardening

Objective: To carry out the morphological characterization of Heliconia uxpanapensis x Heliconia latispatha var. Scarlet for varietal registration purposes. Design, Methodology and Approximation: By means of rhizomes division of 71-1 plant from a plot of H. uxpanapensis x H. latispatha segregant plants (F2), twelve plants (tillers) were generated, planted, and cultivated in open field under 30% of natural shade. Morphological characterization was methodic conducted using the Technical Guide descriptors for Heliconias designed by the National Seed Inspection and Certification Service (SNICS, 2023). Results: Morphological characters of the clones from the 71-1 segregant plant, tested with the SNICS Technical Guide descriptors, were constant so that a differentiation could be make between the Scarlet and Karely, a reference variety found in the Guide. Scarlet variety’s primary distinctive characteristics are the red color, high brilliance, and the revolute-involute margins of their bracts. Their inflorescence morphological characteristic suggest they can be cultivated for cut flower and gardening.  Study limitations and implications: In order for Scarlet variety express, their characteristics of intense color and bracts brightness, they have to be cultivated under 30% of shade. Findings and conclusions: Based on the Technical Guide descriptors for heliconias varietal description (SNICS, 2023), the Scarlet variety differentiates from the Karely (reference variety) as it presents a stability-distinction-homogeneity. For this reason, the varietal registration seems appropriate.Objective: To carry out the morphological characterization of Heliconia uxpanapensis X Heliconia latispatha var.

Evaluation of Microstructural and Mechanical Behavior of AHSS CP780 Steel Welded by GMAW-Pulsed and GMAW-Pulsed-Brazing Processes

Joints of complex phase 780 (CP-780) advanced high strength steel (AHSS) were carried out by using an ER-CuAl-A2 filler metal for the gas metal arc welding pulsed brazing (GMAW-P- brazing) process and the ER-80S-D2 for the GMAW-P process employing two levels of heat input. The phases in the weld bead and HAZ were analyzed, and the evaporation of zinc by means of scanning electron microscopy (SEM) was also monitored. The mechanical properties of the welded joints were evaluated by tension, microhardness and vertical impact tests. It was found that there was greater surface Zn evaporation in the joints welded with the GMAW-P process as compared to the GMAW-P-brazing process. The best results in tensile strength were observed in the joints welded with GMAW-P-brazing process, which increased by ~68% with respect to those of the GMAW-P. This behavior can be attributed to the formation of an intermetallic complex compound Cu-Al-Fe in the fusion line

PERSPECTIVA PSICOSOCIAL DE LOS DERECHOS HUMANOS

Hoy en día es imprescindible abordar el problema de los derechos desde una perspectiva holística que integre la posición que el individuo ocupa en la sociedad y el impacto de los hechos sociales sobre su persona. Esta perspectiva va por lo tanto más allá del enfoque clásico de las violaciones a los derechos civiles y políticos de los ciudadanos sino, también incluye sus derechos económicos, sociales y culturales. Cualquier enfoque de tipo holístico debe entender al ser humano en su ambiente, social, cultural, natural y en función a todas las estructuras existentes, por más sutiles que sean o invisibles que parezcan. Precisamente este libro permite apreciar la dimensión amplia y compleja del ser en sociedad y las interacciones que de ambas partes se generan y las ramificaciones que producen. No es un ejercicio fácil y los editores de este volumen han logrado un salto cuántico al poder congregar en un solo espacio miradas que en otras circunstancias podrían haber sido opuestas y hasta contrarias a nuestra comprensión de problemas que, en efecto, tienen raíces comunes. El libro está dividido en 5 secciones, El espíritu de los tiempos actuales y los Derechos Humanos, Construcción ciudadana y ejercicio de los Derechos Humanos, Violaciones a Derechos Humanos, victimizaciones y su atención, Ejercicio de los Derechos Humanos y situaciones disruptivas y Defensa y defensores de Derechos Humanos.Manuel Gutiérrez Romero Jessica Ruiz Magañ

31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two

Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival

Characterization of a nitroreductase with selective nitroreduction properties in the food- and intestinal-occurring lactic acid bacterium Lactobacillus plantarum WCFS1

Nitroreductases reduce nitroaromatic compounds and other oxidants in living organisms, having interesting implications in environmental and human health. A putative nitrobenzoate reductase encoding gene (lp_0050) was recently annotated in the completed DNA sequence of lactic acid bacterium Lactobacillus plantarum WCFS1 strain. In this research, this L. plantarum gene was cloned and expressed, and the corresponding protein (PnbA) was biochemically characterized. This L. plantarum PnbA reductase is a 216 amino acid residue FMN-flavoprotein, which exhibits 23% identity with Pseudomonas putida and Ralstonia eutropha nitroreductases and <11% identity with those from enterobacteria such as E. cloacae. This reductase also showed 32-43% identity (65-72% similarity) to predicted PnbA proteins from other lactic acid bacteria. It utilized a wide range of electron acceptors including dichlorophenolindophenol (DCPIP), nitroblue tetrazolium (NBT), ferricyanide, and quinones (menadione, benzoquinone), but not pyridinium cations (paraquat and N-methyl-β-carbolines), and it was inhibited by dicoumarol and diphenyliodonium. HPLC-MS and spectroscopic data showed that it specifically catalyzed the reduction of the 4-nitroaromatic group to the corresponding hydroxylamine in the presence of NAD(P)H. Kinetics parameters (Vmax and Km) showed a higher efficiency for the reduction of 2,4-dinitrobenzoate than for the reduction of 4-nitrobenzoate. It was chemoselective for the reduction of 4-nitrobenzoates, being unable to reduce other nitroaromatics. Then, L. plantarum PnbA reductase might be more specific than other microbial nitroreductases that reduce a wider range of nitroaromatic compounds. The physiological and functional role of nitroreductases remain unknown; however, their presence in lactic acid bacteria widely occurring in foods and the human intestinal tract should be of further interestWe thank the MICINN (Spanish government) for support of this research through Grants AGL2006-02414 and AGL2008-01052.

Behavior analysis in college classrooms: A scoping review

We conducted a scoping review of interventions that have been implemented classroom-wide in college classroom settings. We searched nine behavior-analytic journals from 2000 through 2020. We identified 59 studies that met our inclusion criteria and organized them into 13 categories: acceptance and commitment therapy (n = 1), equivalence-based instruction (n = 1), SAFMEDS (n = 4), guided notes (n = 4), response cards (n = 5), group contingencies (n = 5), interteaching (n = 6), programmed instruction, PSI, computer-aided (CA)PSI (n = 7), contingency arrangements (n = 15), feedback (n = 4), online delivery techniques (n = 4), game study sessions (n = 2), and peer-generated examples (n = 1). The interventions have been used with undergraduate and graduate students across various course topics and modalities. Most interventions produced positive results, commonly assessed via quiz and exam scores. This review presents the scope of interventions, their characteristics, and recommendations for future research
