Targeting RAS-MAPK-ERK and PI3K-AKT-mTOR signal transduction pathways to chemosensitize anaplastic thyroid carcinoma
Anaplastic thyroid carcinoma (ATC) is a rare, but aggressive and
chemoresistant tumor with dismal prognosis. Most ATCs harbor mutations
that activate RAS/MAPK/ERK and PI3K/AKT/mTOR pathways. Therefore, we
investigated and correlated the expression of phosphatase and tensin
homolog, pERK, and pAKT proteins as well as mutations of BRAF, RAS, and
p53 genes in samples of patients with ATC. Furthermore, we evaluated the
potential of inhibition of these pathways on chemosensitization of ATC
using 2 thyroid carcinoma cell lines (FRO and SW1736). Our results
revealed a negative correlation between the activity of RAS-MAPK-ERK and
PI3K-AKT-mTOR pathways in samples of patients. To be specific, the
PI3K-AKT-mTOR pathway was suppressed in patients with activated NRAS or
high pERK expression. In vitro results suggest that the inhibition of
either RAS-MAPK-ERK or PI3K-AKT-mTOR components may confer sensitivity
of thyroid cancer cells to classic chemotherapeutics. This may form a
basis for the development of novel genetic-based therapeutic approach
for this cancer type.Ministry of Education, Science and Technological Development, Republic

Closure of persistent oro-nasal fistula with removable obturator denture
Introduction. Cleft lip and cleft palate are relatively common congenital deformities. Patients with clefts require multidisciplinary treatment approach and a team which may include a maxillofacial surgeon, orthodontist, speech therapist, pediatrician, prosthetician, psychologist, as well as the relevant experts who may be of help in restoring the function of the orofacial system. Case report. The paper describes a case of prosthetic rehabilitation of an edentulous female patient with oronasal fistula, after multiple surgical interventions performed in various medical institutions in order to treat her cleft primary and secondary palate. Conclusion. Well planned prosthetic treatment of adult patients with cleft palate and total edentulousness can produce satisfactory results in view of both function and esthetics
