Modulating the dose-rate differently affects the responsiveness of human epithelial prostate- and mesenchymal rhabdomyosarcoma-cancer cell line to radiation.

CONCLUSION The present results indicate that a stronger cytotoxic effect was induced by modulating the dose-rate in a cancer cell-dependent manner, this suggesting that choose the dose-rate based on the individual patient's tumor characteristics could be strategic for effective RT exposures.

Abstract Achilles tendon rupture is an increasingly common problem with an aging population participating in high-level physical activities. Appropriate treatment has been debated for decades, but good outcomes have been reported after conservative and surgical management. The development of minimally invasive surgical techniques for Achilles repair has reduced the incidence of complications and maintained the high level of function reported after open surgery. The Achilles Midsubstance SpeedBridge repair is a newer minimally invasive technique that has demonstrated promising results and is the authors' preferred ...

Study Design.. A meta-analysis. Objective.. The goal of this study was to accurately evaluate the risk ratio (RR) of recurrence in chordoma patients with wide margin after removing the tumors using surgery, compared with inadequate margin (intralesional or marginal). Summary of Background Data.. As a rare malignant bone cancer, the more effective treatment for sacral chordoma is still surgical resection. However, there is no convincing evidence and risk ratio about sacral chordoma patients would be benefit from which kind of surgical margin. Methods.. We searched the PubMed, Cochrane Library, Web of Science, and...

Conclusion. Patients with positive surgical margins benefit from adjuvant RT. Optimal OS is associated with adjuvant RT administered with advanced techniques and cumulative dose more than 65 Gy. Level of Evidence: 4

Purpose of review Refractive surgery is one of the most popular elective procedures performed in the world. Given that dry eye is a common complaint following keratorefractive surgery, evaluation, and treatment of periocular conditions that further predispose the patient to dry eye symptoms is an important part of the presurgical assessment. Periocular conditions and surgeries can also affect the ocular surface and keratometry, and should be addressed. For example, ptosis, orbital fat herniation, ectropion, and eyelid masses have been shown to induce corneal topography changes and astigmatism. The oculoplastic considerat...

Authors: Carkic J, Nikolic N, Nisevic J, Lazarevic M, Kuzmanovic-Pficer J, Jelovac D, Milasin J Abstract Oral carcinoma is the sixth most common malignancy worldwide, with survival rates of approximately 50%. The major type of oral cancer, present in 90% of the cases, is oral squamous cell carcinoma (OSCC). The genetic background predisposing an individual to OSCC is complex and largely unknown. Studies have suggested that endothelial nitric oxide synthase (eNOS) gene polymorphisms modulate the cancer risk, prompting us to assess the impact of three functional eNOS gene polymorphisms on OSCC risk. The present study...

Purpose of review Genome instability has long been implicated as a primary causal factor in cancer and diseases of aging. The genome is constantly under attack from extrinsic and intrinsic damaging agents. Uracil misincorporation in DNA and its repair is an intrinsic factor resulting in genomic instability and DNA mutations. Additionally, the presence of uracil in DNA can modify gene expression by interfering with promoter binding and transcription inhibition or upregulation of apoptotic proteins. In immune cells, uracil in DNA drives beneficial genomic diversity for antigen-driven immunity. This review addresses disease...

Al-Dayel F, Al-Kuraya KS Abstract Sanger Sequencing and immunohistochemistry was employed to investigate the TERT promoter mutations and TERT protein expression with their association to clinicopathological characteristics in over 2200 samples of Middle Eastern origin from 13 different types of cancers. The TERT promoter mutations were most frequently present in bladder cancer (68.6%), followed by central nervous system tumors (28.7%), thyroid cancer (15.4%), prostate cancer (9.3%), endometrial carcinoma (3.7%), rhabdomyosarcoma (1.4%), colorectal cancer (1%), epithelial ovarian carcinoma (0.7%) and breast cancer ...
