Ammonia scavenger and glutamine synthetase inhibitors cocktail in targeting mTOR/β-catenin and MMP-14 for nitrogen homeostasis and liver cancer.

The glutamine synthetase (GS) facilitates cancer cell growth by catalyzing de novo glutamine synthesis. This enzyme removes ammonia waste from the liver following the urea cycle. Since cancer development is associated with dysregulated urea cycles, there has been no investigation of GS's role in ammonia clearance.

Effect of vitamin D supplementation on management of anemia in hemodialysis patients with vitamin D deficiency: A double-blind, randomized, controlled trial.

Introduction: Anemia and vitamin D deficiency are common problems among hemodialysis (HD) patients. This study aimed to assess the impact of correction of vitamin D deficiency with vitamin D supplementation on the improvement of anemia in patients with end-stage renal disease (ESRD) on maintenance HD.

Methods: This double-blind, randomized, controlled study included 100 anemic HD patients with vitamin D deficiency who were randomly divided using the closed envelop method into two groups (1:1).

Bone marrow mammaglobin-1 (SCGB2A2) immunohistochemistry expression as a breast cancer specific marker for early detection of bone marrow micrometastases.

Despite all the advances in the management of breast cancer (BC), patients with distance metastasis are still considered incurable with poor prognosis. For that reason, early detection of the metastatic lesions is crucial to improve patients' life span as well as quality of life. Many markers were proposed to be used as biomarkers for metastatic BC lesions, however many of them lack organ specificity.
