Sarcomas are rare tumors divided into two categories: soft tissue sarcomas and bone sarcomas. A soft tissue mass measuring more than 5 cm, deep, growing, atypical or symptomatic should be investigated further and referred to a specialized center. A percutaneous image-guided biopsy should always be performed in suspicious cases. Standard treatment is surgical. Radiotherapy and chemotherapy should be discussed in a multidisciplinary meeting. Recurrence is frequent and close follow-up of patients over the long term is necessary. A high degree of suspicion is required for any atypical abdominal lesion and the patient should be referred to a specialized sarcoma center as soon as possible instead of performing a surgical biopsy.

Extraskeletal osteosarcoma (ESOS) is a very rare malignant tumor. This study aimed to provide more evidence about the natural history and clinical features of ESOS, and clarify the impact of chemotherapy (CT) and radiotherapy (RT) on patient survival and postoperative recurrence for the sake of gaining a better understanding about the disease. Patient/tumor characteristics, recurrence, treatment, and follow-up durations were collected by searching studies in PubMed, Web of Science, Ovid, Elsevier, SpringerLink, Chinese National Knowledge Infrastructure (CNKI), and WAN FANG Data before June 30, 2023.

Guided tissue regeneration (GTR) and guided bone regeneration (GBR) are two common dental regenerative procedures used to repair periodontal defects caused by periodontitis. In both procedures, a barrier membrane is placed at the interface between the soft tissue and the periodontal defect, serving to impede the infiltration of soft tissue while creating a secluded space for periodontal regeneration. Recently, barrier membranes based on chitosan (CS) have emerged as a promising avenue for these applications.

Emerging evidence suggests that circular RNAs (circRNAs), a class of non-coding RNAs, play a critical role in the progression of several cancers, including osteosarcoma (OS). In this study, we focused on a specific circRNA, hsa_circ_0002005, derived from the mesoderm-induced early response 1 family member 2 (MIER2) gene. We determined the expression levels of hsa_circ_0002005 in OS samples through the use of real-time quantitative polymerase chain reaction (RT-qPCR).

Background: Vancomycin has been the preferred treatment for MRSA infections. However, newer drugs are necessary due to the increasing prevalence of MRSA isolates that are less susceptible to vancomycin. Levonadifloxacin its a prodrug alalevonadifloxacin, novel quinolones with broad spectrum anti-MRSA activity.
