CT45A1 promotes the metastasis of osteosarcoma cells in vitro and in vivo through β-catenin
Cell Death and Disease, 2021 Increased expression of cancer/testis antigens (CTAs) is reported in various tumors. However, the unique role of CTAs in tumor genesis has not yet been verified.

Deep Model with Siamese Network for Viability and Necrosis Tumor Assessment in Osteosarcoma [PDF]
, 2019 Osteosarcoma is the most common primary malignant bone tumor, which has high mortality due to easy lung metastasis. Osteosarcoma is a highly anaplastic, pleomorphic tumor with a variety of tumor cell morphology, including fusiform, oval, epithelial, lymphocyte like, small round, transparent cells, etc.

Osteosarcoma Tumor Detection using Transfer Learning Models [PDF]
arXiv, 2023 The field of clinical image analysis has been applying transfer learning models increasingly due to their less computational complexity, better accuracy etc. These are pre-trained models that don't require to be trained from scratch which eliminates the necessity of large datasets.

The Journal of Hand Surgery, 2021 Osteogenic sarcoma is a malignant tumor that rarely affects the hand. When it does, it most often involves the phalanges or metacarpal heads. We present the case of a 51-year-old woman with a low-grade osteosarcoma affecting the trapezium bone of her left hand. A total trapeziectomy with partial removal of the first metatarsal, scaphoid, trapezoid, and

Antibacterial effects of natural compounds on biofilm formation of Streptococcus mutans
Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1426-1433, December 2022., 2022 Abstract Streptococcus mutans is the main cariogenic pathogen in the oral cavity, considered to contribute toward oral diseases. S. mutans is predominantly entrapped in plaque biofilms. Objectives In this study, we surveyed the antibacterial activity of natural compounds in terms of the biofilm production of S. mutans. Material and Methods We extracted

Deep Learning-Based Objective and Reproducible Osteosarcoma Chemotherapy Response Assessment and Outcome Prediction [PDF]
arXiv, 2022 Osteosarcoma is the most common primary bone cancer whose standard treatment includes pre-operative chemotherapy followed by resection. Chemotherapy response is used for predicting prognosis and further management of patients. Necrosis is routinely assessed post-chemotherapy from histology slides on resection specimens where necrosis ratio is defined ...

Telangiectatic Osteosarcoma [PDF]
Journal of Orthopaedic Surgery, 2013 Purpose. To review records of 8 patients with telangiectatic osteosarcoma (TOS) and determine whether pathologic fractures correlate with recurrence and survival. Methods. Records of 4 men and 4 women aged 17 to 44 (mean, 28) years treated for TOS were reviewed. Results. Of the 8 patients, 4 developed a pathologic fracture and 4 did not. In each group,

Molecular testing of soft tissue tumors
Diagnostic Cytopathology, Volume 51, Issue 1, Page 12-25, January 2023., 2023 Abstract Background The diagnosis of soft tissue tumors is challenging, especially when the evaluable material procured is limited. As a result, diagnostic ancillary testing is frequently needed. Moreover, there is a trend in soft tissue pathology toward increasing use of molecular results for tumor classification and prognostication. Hence, diagnosing

Clinical Medicine Insights: Oncology, 2013 Although osteosarcoma represents the second most common primary bone tumor, spinal involvement is rare, accounting for 3%–5% of all osteosarcomas. The most frequent symptom of osteosarcoma is pain, which appears in almost all patients, whereas more than 70% exhibit neurologic deficit. At a molecular level, it is a tumor of great genetic complexity and

Food Science &Nutrition, Volume 11, Issue 1, Page 443-457, January 2023., 2023 Acrylamide triggered macrophage cell apoptosis and autophagy and pyroptosis. ;P2X7 was of great significance in acrylamide‐induced cell death, but was mainly responsible for the regulation of autophagy and pyroptosis. Acrylamide stimulated oxidative stress via P2X7 in macrophage cells.
