Determinación de los niveles de competencia para entrenamiento básico en microcirugía

Revista Colombiana de Cirugía
Introducción. El nivel de competencia es la medida de las habilidades y destrezas que un estudiante debe desarrollar. Con base en ello, nuestro objetivo es determinar los parámetros que permitan evaluar el desempeño de cada participante frente a las ...

Per què on hi ha més biodiversitat, hi ha més plantes exòtiques? [PDF]

, 2012
Investigadores del CREAF-UAB han encontrado los factores que hacen que en las zonas más biodiversas, donde se esperaría menos invasión de plantas exóticas (experimentos realizados lo corroboran), haya, en la práctica, más plantas exóticas y, por tanto ...

Diabetes‐induced vascular calcification is associated with low pyrophosphate and its oral supplementation prevents calcification in diabetic mice

FEBS Open Bio, EarlyView.
Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...

Calcium‐sensing receptor induces the apoptosis of chondrocytes in cooperation with phosphate transporter

FEBS Open Bio, EarlyView.
Excess Ca2+ ions activate the Calcium‐Sensing Receptor (CaSR), which subsequently drives the uptake of excess inorganic phosphate (Pi) via the Pi transporter (Pit−1) in chondrocytes. This mechanism causes a toxic increase in intracellular Pi concentration, ultimately leading to chondrocyte apoptosis and pathological mineralization. Excess extracellular

Establishment of a coculture system for Porphyromonas gingivalis and head and neck squamous cell carcinoma using spheroid culture and LATS inhibition

FEBS Open Bio, EarlyView.
We established a spheroid coculture system enabling viable Porphyromonas gingivalis–HNSCC interactions under normoxic conditions. Inhibition of LATS1/2 maintains tumor cells in an undifferentiated state, which may promote spheroid growth and create a more permissive environment for bacterial persistence.

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

IGF-II Y LA GONADOTROPINA CORIONICA REGULAN LA PROLIFERACION, MIGRACION E INVASION DE CELULAS DE TROFOBLASTO HUMANO.

Acta Biológica Colombiana, 2011
Son conocidas las propiedades del factor de crecimiento similar a la insulina IGF-II y de la hormona Gonadotropina Coriónica (hCG) en la implantación y migración trofoblástica, sin embargo los mecanismos a través de los cuales ejercen sus efectos no han ...

FGFR Like1 drives esophageal cancer progression via EMT, PI3K/Akt, and notch signalling: insights from clinical data and next‐generation sequencing analysis

FEBS Open Bio, EarlyView.
Clinical analysis reveals significant dysregulation of FGFRL1 in esophageal cancer (EC) patients. RNAi‐coupled next‐generation sequencing (NGS) and in vitro study reveal FGFRL1‐mediated EC progression via EMT, PI3K/Akt, and Notch pathways. Functional assays confirm its role in tumor growth, migration, and invasion.

Relationship between fragmentation, degradation and native and exotic species richness in an Andean temperate forest of Chile Relación entre fragmentación, degradación y riqueza de especies nativas y exóticas en un bosque templado andino de Chile

Gayana: Botanica, 2011
Human impact such as forest fragmentation and degradation may have strong effects on native and exotic plant communities. In addition, these human-caused disturbances occur mostly in lowlands producing greater fragmentation and degradation there than in ...

KLK7 overexpression promotes an aggressive phenotype and facilitates peritoneal dissemination in colorectal cancer cells

FEBS Open Bio, EarlyView.
KLK7, a tissue kallikrein‐related peptidase, is elevated in advanced colorectal cancer and associated with shorter survival. High KLK7 levels in ascites correlate with peritoneal metastasis. In mice, KLK7 overexpression increases metastasis. In vitro, KLK7 enhances cancer cell proliferation, migration, adhesion, and spheroid formation, driving ...
