A Very Low-Positioned Aortic Bifurcation.

Anomalies of the aortoiliac arteries are rarely reported and are generally discovered incidentally on imaging performed mostly for investigation of other medical concerns. While aortic bifurcation is typically reported at the fourth lumbar vertebra, variations are possible. We present a case with very low aortic bifurcation, almost at the level of S2, with various other anomalies including a corkscrew left common iliac artery passing just anterior to the bladder dome with pulsation noted during cystoscopy.

Multimodality approach to imaging giant multilocular cystadenoma of the prostate: A rare entity.

Giant multilocular cystadenomas of the prostate or seminal vesicles are rarely reported in literature. We present a case of a 76-year-old male presenting with lower urinary tract symptoms initially perceived as symptoms of benign prostatic hyperplasia. The patient was investigated by employing a multimodality imaging approach of the prostate that included ultrasound, computed tomography, and magnetic resonance imaging, which resulted in an incidental finding of large multiloculated benign cysts originating from the prostate, confirmed by pathological study.

Case report of epithelioid osteoblastoma of the mandible: findings on positron emission tomography/computed tomography and review of the literature.

Epithelioid osteoblastoma is a clinically aggressive subtype of osteoblastoma that favors the mandible and the maxilla. Its histologic features lie on a spectrum between conventional osteoblastoma and low-grade osteosarcoma, thus making it difficult at times to confirm the diagnosis. It is known to have a high risk of recurrence after surgical resection, but it is a benign entity and does not have the propensity to metastasize.

Pancreaticoduodenal Artery Aneurysm Associated with Celiac Trunk Stenosis: Case Illustration and Literature Review.

Pancreaticoduodenal artery aneurysms (PDA) are rare visceral aneurysms. Celiac trunk stenosis represents a common attributable aetiology for those aneurysms. Therefore, an alternative treatment approach, which differs from those isolated aneurysms, is recommended.

Mutagenicity and clastogenicity of native airborne particulate matter samples collected under industrial, urban or rural influence.

Airborne particulate matter has recently been classified by the IARC as carcinogenic to humans (group 1). However, the link between PM chemical composition and its carcinogenicity is still unclear. The aim of the present study was to evaluate and to compare genotoxic potencies of 6 native PM samples collected in spring-summer or autumn-winter, either in industrial, urban or rural area.

Xenobiotic metabolism induction and bulky DNA adducts generated by particulate matter pollution in BEAS-2B cell line: geographical and seasonal influence.

Airborne particulate matter (PM) toxicity is of growing interest as diesel exhaust particles have been classified as carcinogenic to humans. However, PM is a mixture of chemicals, and respective contribution of organic and inorganic fractions to PM toxicity remains unclear. Thus, we analysed the link between chemical composition of PM samples and bulky DNA adduct formation supported by CYP1A1 and 1B1 genes induction and catalytic activities.

Prooxidant and proinflammatory potency of air pollution particulate matter (PM₂.₅₋₀.₃) produced in rural, urban, or industrial surroundings in human bronchial epithelial cells (BEAS-2B).

Compelling evidence indicates that exposure to air pollution particulate matter (PM) affects human health. However, how PM composition interacts with PM-size to cause adverse health effects needs elucidation. In this study, we were also interested in the physicochemical characteristics and toxicological end points of PM₂.
