Neurovascular relationship between abducens nerve and anterior inferior cerebellar artery

We aimed to study the neurovascular relationships between the anterior inferior cerebellar artery (AICA) and the abducens nerve to help determine the pathogenesis of abducens nerve palsy which can be caused by arterial compression. Twenty-two cadaveric brains (44 hemispheres) were investigated after injected of coloured latex in to the arterial system. The anterior inferior cerebellar artery originated as a single branch in 75%, duplicate in 22.7%, and triplicate in 2.3% of the hemispheres. Abducens nerves were located between the AICAs in all hemispheres when the AICA duplicated or triplicated. Additionally, we noted that the AICA or its main branches pierced the abducens nerve in five hemispheres (11.4%). The anatomy of the AICA and its relationship with the abducens nerve is very important for diagnosis and treatment

Effect of exposure time and smoking habit on arsenic levels in biological samples of metal workers in comparison with controls

Yuksel, Bayram/0000-0001-7686-8648WOS: 000438786000011The main goal of this study was to investigate the effect of exposure time and smoking habit on arsenic levels in biological samples of workers occupationally exposed to metals in comparison with non-occupational residents in Turkey. Blood, urine and hair samples were collected from 95 metal workers at Ankara Occupational Diseases Hospital, Turkey. Similarly, 94 hair samples were taken from controls. Arsenic levels in biological samples were measured using Graphite Furnace Atomic Absorption Spectrometry (GFAAS) equipped with Zeeman background correction and Hydride Generation Atomic Absorption Spectrometry (HGAAS). In metal workers; mean hair-arsenic levels of the smokers group (2.05 +/- 1.97 mg As/kg) was found to be significantly higher than the mean of the hair-arsenic levels of non-smokers group 1.80 +/- 1.79 mg As/kg (p<0.05). Mean hair-arsenic levels of exposure time group (4-10 years) was found (2.34 +/- 2.21 mg As/kg) to be significantly higher than the arithmetic mean of exposure time group (1-3 years) (1.39 +/- 1.25 mg As/kg, p<0.01). As for the control group, mean of hair-arsenic levels in the smokers group (0.133 +/- 0.012 mg As/kg) was found to be significantly higher than the mean of the hair-arsenic levels of non-smokers group (0.101 +/- 0.006 mg As/kg, p<0.05). In addition, mean hair arsenic level in metal workers (1.81 +/- 1.79 mg As/kg) was found significantly higher than mean hair arsenic level in control group (0.115 +/- 0.006 mg As/kg, p=0.00). Smoking increased the hair arsenic levels significantly both in metal workers and controls. The hair arsenic levels significantly enhanced with ascending exposure time. In addition, metal workers had significantly higher hair arsenic levels than controls. However, there was no significant effect detected in terms of urine and blood arsenic levels.Turkish Prime Ministry State Planning Organization Research FundTurkiye Cumhuriyeti Kalkinma Bakanligi [2003K1201902]This work was partially published as an abstract poster presentation at the 51th Congress of the European Societies of Toxicology in Porto, Portugal, Toxicology Letters 238 [2] S367, 2015, and financially supported by Turkish Prime Ministry State Planning Organization Research Fund, Grant Number: 2003K1201902
