Gold nanoparticles (AuNP) play an important role against breast cancer while serving as an excellent marker for early diagnosis, chemotherapy drugs and genes regulator. Understanding the interaction of AuNP with the cell surface and changes in the biomechanical properties of the plasma membrane of cancer cells is essential for the...
From literature review, consult a scientific and fieldwork collections, updated the list of wild mammals of the Lake of Xochimilco in Mexico City. 17 species were recorded, of which three species reported in literature, between 1953 and 1980 are added, but no longer were found in the field. That includes...
Los plaguicidas químicos pueden matar una amplia gama de insectos rápidamente y de manera rentable; sin embargo, sus efectos secundarios son problemáticos, pues la presión selectiva conduce a la resistencia de los insectos a los pesticidas provocando daños al ecosistema y efectos tóxicos residuales tanto para los seres humanos como...
A great majority of studies mark the importance of coastal systems, mainly in estuaries due to its high biological, physical and chemical variability as a result of variations in environmental parameters to seasonal level, with greater emphasis on diel level, allowing a closer the behavior of the composition in such...
The cytokine IFN-g plays an important role in the adaptive immune response against Toxoplasma gondii, since it induces effector mechanisms against the tachyzoite, i.e. phagocytosis enhancement of macrophages, neutrophils and natural killer (NK) cells, as well as B cell production of antibodies of the IgG1 and IgG3 subclasses; the later...
The present study compared the A. brasiliensis ATCC 9642 secretome obtained by submerged fermentation using the minimal medium Hill y Kafer with three initial concentrations of sucrose: 20, 40 and 60 g/L. The samples for the analysis of secretomes were taken at the culture time where the maximum rate of...
The epididymal sperm maturation, comprises a series of morphological and biochemical events that alter sequentially to sperm during its transit along the epididymal tubule, which gives them the necessary characteristics to properly perform the oocyte fertilization. It is considered that in most mammals studied, the maturation ends in the distal...
Se registraron 18 especies de Caulerpa en México distribuidas en 304 localidades. El análisis de parsimonia de endemismos (PAE) se realizó para identificar los patrones de distribución de las especies, usando dos unidades geográficas de análisis: una cuadrícula de 2º de latitud x 2º de longitud y las ecorregiones marinas...
UN is a condition that damages the cellular functions of the body progressive way. Is the cause of 45% of global deaths in children under 5 years of age; It has been widely studied the effects at cytogenetic level, however for gene level not have enough reports to show if...
