Glioblastoma multiforme (GBM) is a highly malignant brain tumor with an extremely dismal prognosis, a median survival is12 months. Temozolomide (TMZ) is an alkylating agent widely used to treat cancer, resistance to this drug is often found. One unexplored possibility for overcoming this resistance is a treatment based on concomitant exposure to electromagnetic fields (EMF) and TMZ.

GBM responds weakly to the common cancer treatments such as chemotherapy and radiotherapy and even surgery. Carboplatin is an alkylating agent widely used to treat cancer.

It responds poorly to the most common cancer treatments, such as surgery, chemo- and radiation therapy. Temozolomide (TMZ) is an alkylating agent that has been widely used to treat GBM; resistance to this drug is often found.

The GBM is a malignant brain tumor with high mortality in humans and poorly responsive to the most common type of cancer treatments, such as surgery, chemotherapy and radiation therapy. U87 cells with five experimental groups (I-V) were exposed to various ELF-PEMFs for 2, 4 and 24 h, as follows: (I) no exposure, control; (II) 50 Hz 100 ± 15 G; (III) 100 Hz 100 ± 15 G; (IV) 10 Hz 50 ± 10 G; (V) 50 Hz 50 ± 10 G.

This study was carried out to evaluate the feasibility and therapeutic potential of autologous bone marrow cell (BMC) transplantation in 11 complete spinal cord injured patients at thoracic level.
Methods And Materials: This nonrandomized clinical trial compared the results of autologous BMC transplantation into cerebrospinal fluid (CSF) via lumbar puncture (LP) in 11 patients having complete SCI, with 20 patients as control group who received conventional treatment without BMC transplantation.
Glioma remains the most challenging solid organ tumor to treat successfully. Based on the capacity of stem cells to migrate extensively and target invading glioma cells, the transplantation of stem cells as a cell-based delivery system may provide additional tools for the treatment of gliomas. In addition to the use of modified stem cells for the delivery of therapeutic agents, unmodified stem cells have been shown to have growth-suppressing effects on tumors in vitro and in vivo.

Objective: To evaluate the effects of atorvastatin on angiogenesis in experimental disc degeneration in rat.
Summary Of Background Data: Back pain is strongly associated with degenerated intervertebral disc and management of this condition is still empirical.
Study Design: This study measured the frequency of lumbar intervertebral disc nucleus pulposus microscopic calcification and angiogenesis in adult patients undergoing discectomy compared to normal cadavers.
Objective: The results were compared to determine the relationship between disc microscopic calcification with disc degeneration type, histopathological angiogenesis, patients' age, gender, and duration of symptoms.
Summary Of Background Data: True frequency of microscopic calcification in normal or degenerated lumbar discs have not been fully defined nor linked to disc degeneration type and angiogenesis.
Background: It is important to find out the skull's anatomic indices with computed tomography (CT), especially the skull's dimensions according to the patients age and sex, because it can give important results in neurosurgery. We will also describe the skull's parameters among the Kerman population.
Method: Of the 2000 CT scans taken after head trauma injury in Kerman province from June 2002 to September 2006, we analyzed 1034 good quality films.
Background: Limited reports exist about intracranial incidental findings on computed tomography (CT) imaging. We studied the frequency of incidental findings on 3000 brain CT scans of trauma patients.
Methods: Three thousands standard brain CT scans of trauma patients were evaluated for some incidental findings.
