A systematic review of oral herpetic viral infections in cancer patients: commonly used outcome measures and interventions.

Purpose: To review the literature for outcome measures for oral viral infections in cancer patients. A secondary aim was to update the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) clinical practice guidelines for the management of oral viral infections in cancer patients.

Methods: Databases were searched for articles published in the English language, 1981-2013.

Glioma morphology and tumor-induced vascular alterations revealed in seven rodent glioma models by in vivo magnetic resonance imaging and angiography.

Purpose: To evaluate the added value of non-contrast-enhanced MR angiography (MRA) to conventional MR imaging for a detailed characterization of different rodent glioma models.

Materials And Methods: Intracerebral tumor cell implantation and chemical induction methods were implemented to obtain rat C6, 9L/LacZ, F98, RG2, and ethyl-nitrosourea (ENU) -induced glioma models, a human U87 MG tumor model as well as a mouse GL261 glioma model. MR assessments were regularly conducted on a 7 Tesla Bruker BioSpin system.

Osteoradionecrosis in cancer patients: the evidence base for treatment-dependent frequency, current management strategies, and future studies.

Purpose: The purpose of this study is to review the evidence base from 1990 to 2008 to (1) clarify the impact of cancer therapies on prevalence of osteoradionecrosis (ORN) in head and neck cancer patients, and to (2) evaluate management strategies and their consequences on quality of life and cost of care.

Methods: Articles were selected for the time period beginning after 1989, excluding the 1990 NCI monograph articles from the 1989 NIH-sponsored Oral Complications in Cancer Therapy Symposium that was published in 1990. The search included both Medline/PubMed and Embase and was limited to humans.

Multiparametric assessment of the anti-glioma properties of OKN007 by magnetic resonance imaging.

Purpose: To demonstrate that OKN007, a disulfonyl derivative of phenyl-tert-butyl nitrone (PBN), has anti-glioma activity in the clinically relevant C6 rat glioma model using multi-parametric magnetic resonance imaging.

Materials And Methods: Twenty-one rats were intracerebrally implanted with C6 cells and administered OKN007 or kept as controls. Animals were monitored with MRI at 7 Tesla (T), using morphologic, diffusion-weighted and perfusion imaging, followed by histology and Western blots of angiogenesis and inflammatory markers.

Therapeutic exercise.

Therapeutic exercise is a key component of any rehabilitation program and should be included as part of the concurrent care of any patient whether that patient has two or four legs. Physical therapists have been utilizing therapeutic exercises with great success since the conception of the profession in the beginning of the twentieth century and it has been demonstrated to be fundamental in improving function, performance and disability. Therapeutic exercise can consist of a variety of exercises inclusive of balance, strengthening, range of motion, endurance, and plyometric activities.

Phenyl-tert-butylnitrone induces tumor regression and decreases angiogenesis in a C6 rat glioma model.

The prognosis of patients who are diagnosed with glioblastoma multiforme is very poor, due to the difficulty of an early and accurate diagnosis and the lack of currently efficient therapeutic compounds. The efficacy of phenyl-tert-butylnitrone (PBN) as a potential anti-glioma therapeutic drug was assessed by magnetic resonance (MR) imaging (T(1)/T(2)-weighted imaging) and MR angiography (time-of-flight imaging, in conjunction with a Mathematica-based program) methods by monitoring morphologic properties, growth patterns, and angiogenic behaviors of a moderately aggressive rat C6 glioma model. MR results from untreated rats showed the diffusive invasiveness of C6 gliomas, with some associated angiogenesis.

In vivo detection of c-MET expression in a rat hepatocarcinogenesis model using molecularly targeted magnetic resonance imaging.

The multifunctional growth factor scatter factor/hepatocyte growth factor and its tyrosine kinase receptor, c-MET, have been implicated in the genesis and malignant progression of numerous human malignancies, including hepatocellular carcinomas. The incidence of hepatocellular carcinomas in the United States has increased noticeably over the past two decades and is listed as the fifth major cancer in men worldwide. In this study, we used a choline-deficient l-amino acid (CDAA)-defined rat hepatocarcinogenesis model to visualize increased in vivo expression of the c-MET antigen in neoplastic lesion formation with the use of a super paramagnetic iron oxide (SPIO)-anti-c-MET molecularly targeted magnetic resonance imaging (MRI) contrast agent.

Amyloid-beta peptide is toxic to neurons in vivo via indirect mechanisms.

We have studied the neurotoxicity of amyloid-beta (Abeta) after a single unilateral intravitreal injection. Within the retina apoptotic cells were seen throughout the photoreceptor layer and the inner nuclear layer but not in the ganglion cell layer at 48 h after injection of Abeta(1-42) compared to vehicle control and control peptide. At 5 months, there was a significant reduction in total cell numbers in the ganglion cell layer in Nissl stained retinas.
