The Effect Of Doxorubicin And Thioridazine On Squamous Carcinoma Cell Line, Bassant Mahmoud Moustafa

Future Dental Journal

Abstract

Background: Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers occupying the sixth position worldwide. PI3k/Akt signaling pathway plays a significant role in regulating diverse cellular functions. This includes cell growth, proliferation and survival via inhibition of apoptosis, transcription and protein synthesis. One of the most acknowledged and approved chemotherapeutic agents is Doxorubicin (DOX) which is a non- selective class I anthracycline. In spite of DOX being one of the most acknowledged chemotherapeutic agents, its use has been limited by its toxic side effects and the development of chemoresistance. Nowadays, Thioridazine (TZ) which is …

Mesenchymal Chondrosarcoma Simulating A Periodontal Disease: A Case Report, Adham Fahmy, Abanoub Selim, Yara Youssef, Iman Mostafa, Hala El-Kammar

Future Dental Journal

Mesenchymal chondrosarcoma (MCS) is a rare high-grade variant of chondrosarcoma. MSC`s represent about 1% to 9% of chondrosarcomas. Less than 500 cases of MCS have been reported in literature, so far. As opposed to other variants, MSC develops outside of the bone in almost third of the cases. Pain and swelling are the most common symptoms at presentation. The overall prognosis of MSC is poor, with frequent distant metastases. Histopathologically, MCS typically exhibits a biphasic pattern consisting of both small cells, and islands of atypical cartilage. The immunohistochemical profile of this lesion overlaps with several other entities. Resection with wide …

Biofilm Forming Ability Of Bacteria Isolated From Dental Caries: With Reference To Streptococcus Species, Sonali Kaustubh Ambulkar, Vidya Tale, Abhijit Jadhav, Komal Kulkarni

Future Dental Journal

Dental caries is formed by the group of microorganisms attached to a tooth surface embedded in a matrix of polymers. Biofilm plays an important role in the development of dental caries, plaque and other periodontal diseases. The present study is aimed to isolate, identify and characterize bacteria from dental caries. The ability of biofilm formation of these isolates was confirmed by Congo red agar method, Tube method and Microtitre plate method. High biofilm-forming bacteria were identified by 16S rRNA sequencing. Streptococcus mutans, Streptococcus anginosus, Enterococcus faecalis and Rothia dentocariosa are the predominant biofilm forming bacteria associated with dental caries.
