Expression of DR4, DR5, FAS, Caspase-8 and, DDIAS Genes in AML Patients.

Background: Acute myeloid leukemia (AML) is the most common acute leukemia in adults and accompanies a worse survival. In this study, gene expression levels of 5 key players of apoptosis, including DR4, DR5, FAS, caspase 8, and DNA damage-induced apoptosis suppressor (DDIAS), have been evaluated in AML patients compared with controls, aiming to evaluate their possible role and prognostic impact.

Methods: This cross-sectional study was performed in the Cancer Molecular Pathology Research Center, Mashhad University of Medical Sciences.

Expression of Vascular Endothelial Growth Factor A and Its Type 1 Receptor in Supratentorial Neoplasm.

Background: Vascular endothelial growth factor (VEGF) is one of the primary angiogenesis regulators in solid cancers. Brain solid tumors are life-threatening diseases in which angiogenesis is an important phase of tumor development and progression. In the present study, VEGF-A and VEGF receptor (VEGF-R1) gene expression was evaluated in CNS brain tumors.

Spinal myelolipoma - an extremely rare pathology within the lumbar spine: a case report and literature review.

Myelolipoma is a benign tumor containing mature adipose cells and a combination of myeloid and erythroid elements. This tumor is typically found in the adrenal glands; however, it has been detected outside the adrenal glands in rare cases. We report an extremely rare case of myelolipoma in the lumbar spine causing significant neural compression due to the involvement of the posterior spinal elements.

Polyomavirus Associated Nephropathy: Frequency and Graft Survival Analysis in Northeast of Iran.

Background & Objective: Polyomavirus-associated nephropathy (PVAN), mainly caused by the BK virus, is one of the most important infectious complications of kidney transplantation. The leading histopathologic characteristics of PVAN is viral cytopathic effects, such as nucleomegaly with smudged or clumped chromatin and intranuclear ground-glass inclusion, mostly in tubular epithelial cells. Moreover, tubular necrosis, tubulitis, interstitial inflammation, atrophy, and fibrosis have been noted.

A rare case of disseminated tuberculosis; multiple intracranial and intramedullary tuberculomas with concurrent tuberculous spondylitis and meningitis.

Concomitant presentation of intracranial and intramedullary tuberculomas is a rare entity. We report a 38-year-old immunocompetent woman with intramedullary and intracranial tuberculomas with concurrent tuberculous spondylitis and meningitis, who presented with paraparesis and back pain. Despite initial antituberculous therapy, the patient's neurologic status deteriorated with the development of paraplegia.

Immunohistochemical expression of apoptosis regulators in squamous cell carcinoma of the cervix and their association with human papillomavirus 16/18 subtypes.

Background: Human papillomavirus (HPV) infection is an important aetiological factor in squamous cell carcinoma (SCC) of the cervix. Limited studies have been focused on the differences between carcinogenesis of SCCs with and without HPV infection.

Aims: The main goal of this study is to determine the expression of some of the apoptotic pathway regulators, including P53, Bax and Bcl2 in SCCs with and without high risk HPV 16/18 infection.
