Polymorphic Variants in 5'-UTR Regions of the RAD51 Gene are Associated With RAD51 Expression and Triple-Negative Breast Cancer (TNBC): A Case-Control Study.

Breast cancer is a heterogeneous disease at morphologic and molecular levels, which is considered the most commonly occurring cancer in women. RAD51, a DNA-repairing protein, involves homologous recombination and has a vital role in genome stability. Polymorphism of the RAD51 gene, and its overexpression, has been proposed to be associated with the development of breast cancer.

Mastalgia as an atypical presentation of hepatocellular carcinoma: a case report.

Background: As the incidence of hepatocellular carcinoma (HCC) diagnoses in Saudi Arabia has recently increased due to better diagnostic techniques, the incidence of diagnosed HCC metastasis has also increased. Here, we report a case of HCC metastasis to the rib with an initially atypical presentation of mastalgia caused by extrahepatic metastasis.

Case Presentation: A 31-year-old woman with a prior hepatitis B viral infection presented with a mass in the left breast accompanied by mastalgia for a 6-month duration.

Effect of new neuronal growth factor on healing of sciatic nerve in rats.

Objective: The study aimed to investigate the effect of a new peptide new nerve growth factor (NNGF) on the healing of divided sciatic nerves in rats.

Material And Methods: Twenty Sprague-Dawley rats of 250-300g were divided into two groups (group 1 - study group and group 2 - control group). Under ketamine intramuscular anesthesia sciatic nerves were exposed, divided and repaired using 10/0 dexon.
