Doping with anabolic androgenic steroids (AAS): Adverse effects on non-reproductive organs and functions.
Abstract Since the 1970s anabolic androgenic steroids (AAS) have been abused at ever increasing rates in competitive athletics, in recreational sports and in bodybuilding. Exceedingly high doses are often consumed over long periods, in particular by bodybuilders, causing acute or chronic adverse side effects frequently complicated by additional polypharmacy. This review summarizes side effects on non-reproductive organs and functions; effects on male and female reproduction have been recently reviewed in a parallel paper. Among the most striking AAS side effects are increases in haematocrit and coagulation causing...

Abstract 1852: Merlin/NF2 is associated with elevated aromatase expression and estrogen formation in human liver tissues and liver cancer cells: An unifying model for hepatocellular carcinoma development and progression
It is recognized that the product of neurofibromatosis type 2 (NF2) tumor suppressor gene, also referred to as Merlin/neurofibromin, is implicated in the homeostatic regulation of the liver stem cell niche through the control of abundance and signaling of epidermal growth factor receptor (EGFR), with a mechanism independent of the Mst/Lats/Yap Hippo pathway [1]. We have previously reported that locally elevated estrogen formation, driven by abnormally high expression and function of the aromatase enzyme, may be implicated in both development and progression of human hepatocellular carcinoma (HCC) through the activation of ...

Mitochonic Acid 5 (MA-5), a Derivative of the Plant Hormone Indole-3-Acetic Acid, Improves Survival of Fibroblasts from Patients with Mitochondrial Diseases.
T, Tomioka Y, Toyomizu M, Ito S, Osaka H, Hayashi K, Abe T Abstract Mitochondria are key organelles implicated in a variety of processes related to energy and free radical generation, the regulation of apoptosis, and various signaling pathways. Mitochondrial dysfunction increases cellular oxidative stress and depletes ATP in a variety of inherited mitochondrial diseases and also in many other metabolic and neurodegenerative diseases. Mitochondrial diseases are characterized by the dysfunction of the mitochondrial respiratory chain, caused by mutations in the genes encoded by either nuclear DNA or mitochondrial DNA...

Clinical Reasoning: A 66-year-old man with recurrent multi-territory infarcts
A 66-year-old man was referred to our center for evaluation of recurrent infarcts in multiple vascular territories over the preceding 6 months (figure 1). The patient first presented with a 3-month, stuttering course of transient neurologic deficits, including right arm and leg hemiparesis, expressive aphasia, and right homonymous hemianopia. He was initially evaluated at a community Stroke Prevention Clinic. His medical history was significant for several classic vascular risk factors: coronary artery disease requiring a coronary artery bypass graft, dyslipidemia for which he was taking atorvastatin 20 mg daily, and obstr...

The Variation with Age of 67 Macro- and Microelement Contents in Nonhyperplastic Prostate Glands of Adult and Elderly Males Investigated by Nuclear Analytical and Related Methods.
Abstract To clarify age-related changes of 67 macro- and microelement contents in prostate gland of adult and geriatric males, a quantitative measurement by five analytical methods was performed. The nonhyperplastic prostate glands of 65 subjects (European-Caucasian aged 21-87 years) were investigated by energy dispersive X-ray fluorescence (EDXRF), instrumental neutron activation analysis with high resolution spectrometry of short-lived radionuclides (INAA-SLR), instrumental neutron activation analysis with high resolution spectrometry of long-lived radionuclides (INAA-LLR), inductively coupled plasma atomic emi...

Diagnosis of an aortic valvular lesion
From the question on page 719 Clinical introduction A 59-year-old woman with hypertension presented with right-sided weakness and vision loss. Her vital signs were normal; cardiopulmonary exam was significant for a systolic and diastolic murmur. MRI of the brain showed multiple chronic bilateral infarctions, and Doppler ultrasound revealed acute left lower extremity deep vein thrombosis. Transthoracic echocardiography (TTE) to determine cardioembolic source of stroke was significant only for severe aortic valve regurgitation. To assess for cardiac vegetations, transoesophageal echocardiography (TEE) was performed (figure 1...

Treatment and survival of non-alcoholic steatohepatitis associated hepatocellular carcinoma
Background: The incidence of non-alcoholic steatohepatitis (NASH) is increasing worldwide and a poorly defined subset of patients develops end-stage liver disease and hepatocellular carcinoma (HCC). Differences in the biological behaviour, tumour characteristics, associated risk factors, treatment outcomes and overall survival of patients with NASH-HCC remain poorly defined. The aim of this study was to determine and analyze these differences in a large clinical cohort to guide treatment decisions. Methods: 1119 patients with HCC treated in an 11 year period at the University Medical Centre of the Johannes Gutenberg Unive...

Teaching NeuroImages: Radiation-associated symptomatic carotid artery disease with ipsilateral radiodermatitis
A 68-year-old man with a history of squamous cell carcinoma of the tongue treated with external beam radiation therapy in 2007 presented in 2013 with acute onset expressive aphasia and right lower facial weakness. MRI confirmed an acute infarct in the left frontal cortex. CT angiography revealed occlusion vs critical stenosis of the left internal carotid artery, new from 2007. Examination of the patient's neck revealed ipsilateral radiodermatitis (figure). Therapeutic neck irradiation has been associated with accelerated atheromatous disease, carotid artery stenosis, and increased risk of stroke.1,2 Ipsilateral radiodermat...

The Syndrome of Stroke-like Migraine Attacks After Radiation Therapy Associated With Prolonged Unresponsiveness in an Adult Patient
Conclusions: Reduced level of consciousness of such severity and duration as observed here has not previously been described in SMART syndrome. This report, however, suggests that an excellent prognosis can be expected even in cases of prolonged unresponsiveness. The pathogenic mechanisms of SMART syndrome remain unclear, but may involve pathways common to both migraine and epilepsy.

Detection of a Right Carotid Focus of 18F-FDG Predicted an Ischemic Stroke
AbstractA 60-year-old woman was referred into our department for staging of an endometrial carcinoma. In addition to peritoneal and nodes metastases, 18F-FDG PET/CT showed a calcified plaque of the right carotid with focal uptake. One month later, the patient presented left hemiparesis, suggesting a right hemisphere stroke. MRI confirmed frontal infarction in the anterior cerebral artery territory. 18F-FDG is suggested to be a valuable tool to detect vessel wall inflammation; detection of focal arterial uptake on PET/CT suggests unstable plaque and requires urgent patient’s management to prevent vascular events in a popu...

Title: Ritual Risk: Incense Use and Cardiovascular Mortality
This study is of particular significance given that cardiovascular disease is one of the most common chronic diseases in the population worldwide,” says Karin Yeatts, an epidemiologist at the University of North Carolina at Chapel Hill, who has studied indoor air quality in the Middle East. In contrast with outdoor air pollution, incense exposure may be easier for an individual to avoid, but Yeatts says education will be needed to help people understand the risks of these exposures, similar to educational campaigns about cigarette smoking. Limitations to the study include lack of information on the type of incense burned...

Bm-12 * cerebral infarction secondary to pulmonary vein compression and left atrial appendage tumor infiltration as the presenting sign of metastatic squamous cell carcinoma of the base of the tongue
CONCLUSION: Cardiac metastases are rare and non-myxomatous tumor embolization to the brain even rarer especially in the setting of cerebral infarction due to pulmonary vein thrombus. Here we describe a case of multiple acute cerebral infarctions appearing from a proximal source refractory to anticoagulation. Thromboembolism from the pulmonary vein and tumor embolization from cardiac metastases are the likely mechanisms for his clinical presentation and radiographic findings. This case demonstrates the complexity of multiple stroke etiologies in one patient and the importance of cardiac imaging in stroke evaluation, particu...
