En la provincia de Loja en las zonas de Chaguarpamba, Lozumbe y Hacienda Cristal, se colectaron de forma aleatoria muestras de suelo en plantas de café. Para el aislamiento de los microorganismos rizosféricos se realizaron diluciones seriadas hasta 10-5 y se sembraron por triplicado en placas de Petri con agar nutriente para el crecimiento de los microorganismos, se incubaron a 28 ºC durante 72 horas.

During the past decades the achievements made in treating cancers have significantly improved the survival of patients. However, cancer is still one of the leading causes of mortality. It is suggested that treatment failure is mediated by a subpopulation of tumor cells named cancer stem cells that can survive after treatment and promote cancer relapse. Targeting these cells is important to improve cancer therapy. The aim of our study is to determine the effect of a human ribonuclease variant on breast cancer cells grown in 3D and on cancer stem cells.

Although single targeted anti-cancer drugs are envisaged as safer treatments because they do not affect normal cells, cancer is a very complex disease to be eradicated with a single targeted drug. Alternatively, multi-targeted drugs may be more effective and the tumor cells may be less prone to develop drug resistance although these drugs may be less specific for cancer cells. We have previously developed a new strategy to endow human pancreatic ribonuclease with antitumor action by introducing in its sequence a non-classical nuclear localization signal.

This study aimed to examine the prevalence of comorbidities in patients diagnosed with chronic lymphocytic leukemia (CLL), and to assess its influence on survival and cause-specific mortality at a population-based level. Incident CLL cases diagnosed in the Girona province (Spain) during 2008-2016 were extracted from the Girona Cancer Registry. Rai stage and presence of comorbidities at diagnosis, further categorized using the Charlson comorbidity index (CCI), were obtained from clinical records.

The reproductive efficiency of South American camelids as the alpaca is low, with a few number of animals having a good genetic characteristic. The transfer of cryopreserved embryos has great potential to disseminate valuable genetic, but the suitable protocol for such cryopreservation still needs to be developed. In this study, two protocols of vitrification of alpaca embryos were tested.
