Risposte agli stress ambientali in CYSTOSEIRA (C. AGARDH): effetti della temperatura sul contenuto dei composti fenolici

Phenolic compounds are secondary metabolites involved in different protection mechanisms as, for example, against grazers, epiphytes and UV radiation. Seasonal variations of phenolic content in C. amentacea were analysed and laboratory experiments, in which C. amentacea was exposed to an increase of temperature (258C and 308C), were performed. Total phenolic content (TPC) was determined colorimetrically with the Folin\u2013Ciocalteu reagent. In C. amentacea, a seasonal pattern in TPC was observed, with a maximum value in winter-spring. C. amentacea responded significantly to the temperature treatments with a consistent decrease in TPC after 48 h

GIANT MERKEL CELL CARCINOMA OF THE LEFT ARM.CASE REPORT

Merkel cell carcinoma is a rare tumor of dermal origin generally found in sun exposed skin. We report the case of a woman of 76 years old presenting a large vascularized Merkel cell carcinoma (MCC) of the left arm lateral to the elbow joint, infiltrating the muscolo-fascial plane who was treated with surgical therapy and post operative radiotherapy
