Antifungal and anti-biofilm activity of new propane Sulfonyl Hydrazone Against Candida Isolates

AYDIN TERZİOĞLU, Merve | ÖZTÜRK, Ali | ÖZDEMİR ÖZMEN, Ummuhan

Candidiasis is the most frequently encountered fungal disease that ranges from mild mucosal infections to serious candidaemia and disseminated candidiasis. There are only limited classes of antifungal agents available for physicians to combat Candida infections. In addition, biofilm cells display phenotypic traits that resulting in enhanced resistance to antifungal drugs. Therefore, the limited option to combat fungal threat has raised the interest in seeking alternative antifungal compounds. The aim of this study was to investigate the antifungal and anti-biofilm activity of the new Sulfonyl ...Daha fazlası

Could interleukin-33 and its suppressor of tumorigenicity 2 (ST2) receptor have a role in cervical human papillomavirus (HPV) infections?

KULHAN, Nur Gözde | KULHAN, Mehmet | AYDIN, Merve | NAYKİ, Ümit | NAYKİ, Cenk | ULUĞ, Paşa | ATA, Nahit | MERTOĞLU, Cuma | ÇIKMAN, Aytekin | SAYAR, İlyas | TÜRKLER, Can

Why most women can clear human papillomavirus (HPV) infections while others can develop permanent infections. The stimulation of immunotolerance of the immune system of the host by the persistent HPV infection may be the answer to this question. Interleukin-33 (IL-33) may play a role in the pathogenesis of HPV infection, this hypothesis was thought to be due to the rapid release of IL-33 from damaged cells following tissue damage, necrosis, and activation of the inflammasome. Thus, in this study, the role of IL33/suppressor of tumorigenicity 2 (ST2) was emphasized in HPV positive and HPV negat ...Daha fazlası
