Ameliorative Effect of the Oral Administration of Chuquiraga spinosa in a Murine Model of Breast Cancer Induced with 7,12-Dimethylbenz[a]anthracene (DMBA)
Objective: To determine the ameliorative effect of the ethanolic extract of Chuquiraga spinosa (ChS) on 7,12-Dimethylbenz[a]anthracene (DMBA)-induced breast cancer in rats. Methods: 36 female Holztman rats were divided into 6 groups. I) The negative control group received physiological saline (PS). II) ChS-200 group received 200 mg/kg of ChS. III) DMBA group was induced with DMBA (20 mg/Kg) dissolved in PS and administrated orally for 15 weeks. IV) DMBA + ChS-50 group, V) DMBA + ChS-250 group, and VI) DMBA + ChS-500 group, which received the extract orally for 15 weeks after DMBA induction. All data were expressed as mean and standard deviation. One-way analysis of variance (ANOVA) followed by Dunnet test was carried out to compare the mean value of different groups Histopathological analysis was evaluated by using Image J software. Results: Hematology showed that the triglyceride level was significantly lowered (P< 0.01) and high-density lipoprotein (HDL) level was significantly increased (P <0.01) in groups III, IV and V. Also, ChS extract significantly lowered the C reactive protein (CRP) level (P <0.01) and malondialdehyde level (P<0.05). There was a significant decrease in the frequency of DMBA-induced micronucleated polychromatic erythrocyte (P<0.01). Conclusions: Chuquiraga spinosa showed an ameliorative effect on DMBA-induced breast cancer in rats as well as antioxidant, antitumor and antigenotoxic properties.Revisión por pare
Competencias del Docente en Enfermería en la Elaboración de la Planeación Didáctica
Objetivo: Describir el nivel de competencias profesionales para elaborar una planeación didáctica en los docentes de enfermería de una universidad pública del estado de Puebla y Tabasco. Métodos: El diseño del estudio fue cuantitativo, transversal, descriptivo comparativo de dos Instituciones de Educación Superior. El muestreo fue por conveniencia, con una muestra final de 20 docentes de enfermería de pregrado; 10 del estado de Puebla y 10 de Tabasco. Se utilizó una cédula ex profesa de datos personales y se aplicó un instrumento para evaluar las competencias del docente de enfermería en la planeación didáctica, con un total de 12 reactivos. Este instrumento tiene dos dimensiones; conocimientos y habilidades prácticas del docente. Resultados principales: Se muestra que el 40% de los docentes de enfermería tiene un nivel de competencia bajo y el 30% se encuentra entre un nivel moderado y alto con respecto al conocimiento de la planeación didáctica. Asimismo, referente a las habilidades prácticas, el 65% se ubica en nivel de competencia bajo y tan sólo el 15% presenta un nivel de competencia alto. Conclusión general: La planeación didáctica en enfermería es esencial para asegurar que los estudiantes reciban una educación de calidad y estén preparados para enfrentar los desafíos del campo de la enfermería

Morphological identification and characterization of the formation of floral primordium in Vanilla planifolia (Orchidaceae)
ABSTRACT
Objective: To study the formation of floral primordia and individual flower development in the inflorescence of vanilla (Vanilla planifolia Jacks Ex. Andrews).
Design/methodology/approach: The study site was located at Rancho Xanathtlan, in Barriles, municipality of Gutiérrez Zamora, Veracruz. Inflorescence primordia and young inflorescences (racemes) at different stages of development were sampled from three different stem positions: basal (11-15 internodes), middle (6-10 internodes) and distal (1-5 internodes). Four samplings were made from February to May, and five replicates of each stem position were used per sampling date. Observations and characterization were carried out with a stereo microscope.
Results: Seven developmental stages were described for the racemes of V. planifolia: (I) differentiated meristem of the floral inflorescence, (II) appearance of the third bract, (III) initiation of the formation of the racemes, (IV) elongation of the floral primordia, (V) development and growth of the individual floral primordia in the acropetal direction, (VI) anthesis of the inflorescence in the acropetal direction and (VII) complete flowering of the raceme. Five developmental stages of formation of individual flower primordia within the inflorescence were also identified, which occurred from the appearance of the third bract in the acropetal direction.
Limitations on study/implications: Although this study denotes the first observations on the floral phenology of V. planifolia, there are still many questions about the biochemical processes and the interaction of environmental aspects in this floral development.
Findings/conclusions: First aspects of floral formation within the inflorescence as well as floral phenology in Vanilla planifolia were shown.
Keywords: Floral growth, floral phenology, inflorescences, orchids.Objective: To morphologically identify and characterize the formation of floral primordium and the individual flower development in Vanilla planifolia Jacks Ex. Andrews.
Design/Methodology/Approach: Inflorescence primordia and young inflorescences in different development stages were sampled from the stem internodes of the following positions: basal (11-15), middle (6-10), and distal (1-5). Four samples were taken from each stem position from February to May, with five repetitions per sampling date. Observations and characterization were made with a stereo microscope. The study site was located at Rancho Xanathtlan, in Barriles, municipality of Gutiérrez Zamora, Veracruz.
Results: The development of the V. planifolia raceme is described in seven phases: (I) differentiated meristem of the floral inflorescence; (II) appearance of the third bract; (III) initiation of the racemes formation; (IV) elongation of the floral primordium; (V) development and growth of the individual floral primordium in the acropetal direction, (VI) anthesis of the inflorescence in the acropetal direction; and (VII) complete flowering of the raceme. The development of the buds in the raceme is described in five stages from the appearance of the third bract in the acropetal direction.
Study Limitations/Implications: The biochemical processes and the interaction of environmental aspects on the floral development of V. planifolia pose questions that remain unanswered.
Findings/Conclusions: The first aspects of floral formation within the inflorescence of Vanilla planifolia were determined, along with its floral phenology

Seroepidemiological evidence of severe fever with thrombocytopenia syndrome virus infections in wild boars in Nagasaki, Japan
Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease in East Asia. It is thought that the SFTS virus (SFTSV) circulates between ticks and animals in nature and that the virus is transmitted to humans by tick bites. SFTS is endemic to Nagasaki in western Japan; however, epidemiological information regarding SFTSV in Nagasaki is not known. In this study, we performed SFTSV IgG ELISAs and neutralization antibody assays for a seroepidemiological survey using samples from wild boars captured in six areas of Nagasaki. SFTSV seropositive animals were found in three areas. Our findings provide epidemiological information on the distribution of SFTSV in Nagasaki
