Botulinum Toxin A for Oral Cavity Cancer Patients: In Microsurgical Patients BTX Injections in Major Salivary Glands Temporarily Reduce Salivary Prod…

2012

Abstract: In patients suffering from oral cavity cancer surgical treatment is complex because it is necessary to remove carcinoma and lymph node metastasis (through a radical unilateral or bilateral neck dissection) and to reconstruct the affected area by means of free flaps. The saliva stagnation in the post-operative period is a risk factor with regard to local complications. Minor complications related to saliva stagnation (such as tissue maceration and wound dehiscence) could become major complications compromising the surgery or the reconstructive outcome. In fact the formation of oro-cutaneous fistula may cause infection, failure of the free flap, or the patient’s death with carotid b…

Delivery of proteins into living cells by reversible membrane permeabilization with streptolysin-O

2001

The pore-forming toxin streptolysin O (SLO) can be used to reversibly permeabilize adherent and nonadherent cells, allowing delivery of molecules with up to 100 kDa mass to the cytosol. Using FITC-labeled albumin, 10 5 –10 6 molecules were estimated to be entrapped per cell. Repair of toxin lesions depended on Ca 2+ -calmodulin and on intact microtubules, but was not sensitive to actin disruption or to inhibition of protein synthesis. Resealed cells were viable for days and retained the capacity to endocytose and to proliferate. The active domains of large clostridial toxins were introduced into three different cell lines. The domains were derived from Clostridium difficile B-toxin and Clo…

Chemical composition of the essential oil of Elaeoselinum asclepium (L.) Bertol subsp. meoides (Desf.) Fiori (Umbelliferae) collected wild in Central…

2020

In the present study, the chemical composition of the essential oils from flowers and leaves of Elaeoselinum asclepium(L.) Bertol subsp. meoides(Desf.) Fiori collected in Central Sicily was evaluated by GC and GC-MS. The main volatile components of the flowers were alpha-phellandrene (42.5%), terpinolene (15.7%), p-cymene (11.6%) and beta-phellandrene (10.2%), whereas the ones of the leaves were p-cymene (44.0%), alpha-pinene (13.2%), alpha-phellandrene (11.0%), beta-phellandrene (10.2%) and beta-pinene (9.2%). Furthermore, the antibacterial and antifungal activities against some microorganisms infesting historical art craft were determined. The essential oil from leaves (EL) showed to be p…
