Evaluation of the ultrastructure and expression of desmoglein 2 in breast cancer: A novel biomarker

Background and purpose: Breast cancer is the most common malignancy among Iranian women. In recent years, the study of dysfunction in the expression of cell-cell junction genes and the related proteins in the malignant process has been at the center of attention. Materials and methods: In this study, 50 patients were selected who had both cancerous tissue and adjacent healthy tissue. The expression of the desmoglein 2 gene was evaluated. Healthy and cancerous tissue were compared using routine hematoxylin and eosin staining. The total protein was also compared between these two groups. The ultrastructural examination was performed. Results: The real-time polymerase chain reaction results showed a decrease in the expression of the desmoglein 2 gene in all tumor samples compared to the healthy samples (p<0.0001). Besides, receiver operating characteristic curve analysis showed that the area under the curve was equal to 0.98. Transmission electron microscopy microscopic studies revealed a change in the status of desmosomal junctions. Conclusions: Overall, the findings showed that the association between desmoglein 2 gene expression and alterations in cellular connections leads to impaired cellular connections, which is an important risk factor for breast cancer. This result proposed the understudy gene as a new biomarker in the development of breast cancer

Tecnología de semillas sintéticas para la encapsulación y el recrecimiento de puntas de brotes y embriones somáticos de Espárrago officinalis L

Apical buds obtained from Asparagus plant vitro culture and somatic embryos obtained from stem cultivation, explants in MS medium supplemented with mg¹ᶫ 1, 2, 4-D and mg¹ᶫ 1 and Kinetin have been used in this research to produce artificial seeds. We encapsulated apical buds and somatic embryo using 2% sodium alginate and calcium chloride to prepare the artificial seeds. We placed artificial seeds at room temperature (about 25 ° C), in the cold, the temperature of 4 ° C and -18 ° C for different times (15,30,60,90 days) and evaluated the growing power of these seeds in MS and ½MS mediums for further investigations about the viability of seeds. The highest conversion percentage of seedlings in encapsulated embryos (70.01) was related to seed harvested from embryos treated with BA and the highest conversion percentage of seedlings in apical buds (96.54) was obtained from cultivated untreated seeds in MS medium. Encapsulated arteries and buds maintained germination energy and viability with increasing storage time after 90 days of storage at 4 and 25 ° C despite viability reduction while un-capsulated embryos and buds completely lost viability after 60 days of storage at 4 and 25 ° C and seeds stored at -18 ° C completely lost viability after 15 days of storage. In general, the percentage of seed germination and conversion to seedling is higher in seeds cultivated in MS medium compared to seeds cultivated in ½MS medium.En esta investigación se han utilizado yemas apicales obtenidas de cultivo vitro vegetal de espárragos y embriones somáticos obtenidos del cultivo de tallos, explantes en medio MS suplementado con mg¹ᶫ 1, 2, 4-D y mg¹ᶫ 1 y Kinetin para producir semillas artificiales. Encapsulamos yemas apicales y embriones somáticos utilizando alginato de sodio al 2% y cloruro de calcio para preparar las semillas artificiales. Colocamos semillas artificiales a temperatura ambiente (alrededor de 25 ° C), en el frío, la temperatura de 4 ° C y -18 ° C para diferentes tiempos (15,30,60,90 días) y evaluamos el poder de crecimiento de estas semillas. en medios MS y ½MS para futuras investigaciones sobre la viabilidad de las semillas.

El feminismo en Virginia Woolf (Una habitación propia, 1929) y Samiha Khreis (Cuadernos del diluvio, 2003)

[Resumen] Este trabajo pretende arrojar la luz sobre el feminismo, entendido como un conjunto de teorías y prácticas de autoafirmación, con las que múltiples culturas se entrelazan en torno a los derechos de las mujeres. Con un enfoque comparado, se presentan las ideas feministas en el ensayo literario A Room of One’s Own (1929), de la escritora británica Virginia Woolf; y en la novela Dafatir Al-Toufan (2003) de la escritora jordana Samiha Khreis. Tras una breve contextualización histórica y cultural, se pone atención en la influencia de las religiones en los feminismos oriental y occidental. Se aborda la representación literaria de la mujer occidental y sus reivindicaciones a principios del s. XX; y la de la mujer oriental árabe y la lucha por sus derechos a principios del s. XXI. Por último se comentan los puntos en que las obras convergen o divergen, de manera que se ponga en evidencia, acompañada de una breve reflexión sobre las luchas feministas, lo que hay de común o no entre movimientos socio-culturales reflejados en la literatura, por encima de fronteras y marcos temporales y culturales[Abstract] This work aims to shed light on feminism, understood as a set of theories and practices of self affirmation, with which multiple cultures are intertwined around women's rights. With a comparative approach, feminist ideas are presented in the literary essay A Room of One's Own (1929), by the British writer Virginia Woolf; and in the novel Dafatir Al-Toufan (2003) by the Jordanian writer Samiha Khreis. After a brief historical and cultural contextualization, attention is paid to the influence of religions on Eastern and Western feminisms. The literary representation of Western women and their claims at the beginning of the s. XX; and that of the Arab oriental woman and the fight for her rights at the beginning of the s. XXI. Finally, the points in which the works converge or diverge are commented, so as to put in evidence, accompanied by a brief reflection on the feminist struggles, what there is in common or not between socio-cultural movements reflected in the literature, for above borders and temporal and cultural frameworksTraballo fin de mestrado (UDC.FIL).

Genotype-isolate interaction for resistance to Sclerotinia sclerotiorum in sunflower

The sunflower (Helianthus annuus L.) is one of the most important crops grown for edible oil. Sclerotinia sclerotiorum (Lib.) de Bary is a common and widespread pathogen of sunflower. In the present study the reaction of 35 genotypes, including recombinant inbred lines and their parents, M7 mutant lines developed by gamma irradiation, and some genotypes from different geographical origins, were evaluated against eight S. sclerotiorum isolates in controlled conditions. The proportion of the subsequent basal stem lesions was measured 3 days after inoculation. Highly significant differences were observed among sunflower genotypes and S. sclerotiorum isolates, with the isolates interacting differentially with sunflower genotypes. Two genotypes had high partial resistance to all S. sclerotiorum isolates, whereas others were susceptible to all isolates. Isolates of S. sclerotiorum differed in virulence to host genotypes. Some genotypes showed specific interactions with S. sclerotiorum isolates, being resistant to some isolates but susceptible to others. Recom­binant inbred lines used in this study showed different reactions to eight isolates of S. sclerotiorum when compared with their parental lines. The isolate-specific and isolate-nonspecific partial resistant genotypes identified in present experiments should be used in crossing programmes for breeding of durable resistance to Sclerotinia basal stem disease

Evaluation of antimicrobial activity of aqueous extract, ethanol, methanol and ashes two species ramosissimum and telmateia of Equisetum arvense on several bacterial species and Yeast

Introduction: Bacterial infections are one of the major health challenges and authorities in this field are faced with many problems especially bacterial resistance to antibiotics. This study aimed to evaluate the antimicrobial effects of aqueous and alcoholic extracts and the ash of two species of horse tail herb against standard strains of Staphylococcus aureus, Escherichia coli and Candida albicans and investigate its effect on eukaryotic cells.Methods: Aqueous, methanolic and ethanolic extracts and ash were prepared from two horse tail species. In order to evaluate antibacterial function, well diffusion test was used by measuring inhibitory halo diameter on standard strains of Staphylococcus aureus, Candida albicans and E. coli. For determining the minimum inhibitory concentration (MIC) on these strains micro broth dilution method was applied. To evaluate its effect on the eukaryotic cells, blood agar medium was used.Results: Based on agar diffusion test, the halo of no bacterial growth was associated with extracts in different ranges in standard strains. The MIC was determined using the micro broth dilution. These extracts had no effects on red blood cells and did not produce hemolysis on blood agar medium.Conclusion: Horsetail extract can be used to treat fungal and bacterial infections either lonely or in combination with other antimicrobial agents. Due to its antimicrobial potential, it can especially be considered in the cases of drug resistance

QTL mapping of partial resistance to basal stem rot in sunflower using recombinant inbred lines

Basal stem rot, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is an important cause of yield loss in sunflower (Helianthus annuus L.). Quantitative trait loci (QTLs) implicated in partial resistance to basal stem rot disease was identified using the 116 recombinant inbred lines (RILs) from the cross between the sunflower parental lines PAC2 and RHA266. RILs and their parents were arranged in a completely randomized design with six replications and inoculated with a moderately aggressive isolate (SSU107) of S. sclerotiorum under controlled conditions. QTLs were mapped using a recently developed high-density single sequence repeat/ amplified fragment length polymorphism (SSR/AFLP) sunflower linkage map. Analysis of variance showed highly significant differences among the sunflower genotypes for susceptibility to basal stem rot. The frequency distribution of genotypes for susceptibility to disease showed continuous patterns, suggesting that resistance is controlled by a polygenic system. Transgressive segregation for resistance occurred in this cross. Composite interval mapping analysis revealed 7 QTLs for percentage necrotic area, localized on 7 linkage groups. The effects of QTLs were small to moderate indicating a polygenic control of the studied character. However, like any other quantitative trait, it is necessary to confirm the position of the QTLs and carry out fine-scale mapping before marker assisted selection (MAS). LG8 and LG16 are good candidates for further analysis to develop molecular markers for resistance to Sclerotinia disease
