Deuterium quadrupole splittings, of deuterated water, Deltav, in anionic discotic nematic lyomesophases are always much larger than in cationic mesophases. To explore the possible origins of this difference, Deltav and T-1 relaxation times of HDO (H2O 0.2% D2O) and decanol (DeOH 14% alpha-d(2)), ...

The antifungal activity of polygodial, a secondary metabolite extracted from Canelo, on mycelial growth of different Botrytis cinerea isolates has been evaluated. The results show that polygodial affects growth of normal and resistant isolates of B. cinerea with EC50 values ranging between 117 an...

El objetivo fue evaluar la inmunoexpresión de E-cadherina y Vimentina en mucosa oral normal (MON), displasia epitelial oral (DEO) y carcinoma oral de células escamosas (COCE). Se realizó un estudio descriptivo de una serie de casos analizandolos mediante técnica de inmunohistoquímica contra E-cad...

The aim was to evaluate the expression of E-cadherin and Vimentin in oral epithelial dysplasia (OED) and oral squamous cell carcinoma (OSCC), in comparison with normal oral mucosa (NOM) in a descriptive case study using immunohistochemistry. A total of fifty-one (N=51) histological samples were i...
