    Abstract: The present available data on the harmful effects of electronic cigarettes (EC) is inconsistent and contradicting. Even though EC is considered a healthier alternative to the traditional cigarettes, several studies reported a large range of toxic compounds. The objective of this study is to determine whether the mercury found in the solutions used for electronic cigarettes is involved in the initiation and aggravation of endothelial dysfunction found in smoking persons with coronary artery disease (CAD). Endothelial function was evaluated by performing organ bath studies of vascular rings from patients with CAD, and was determined as a response to cumulative doses of endothelial-dependent/independent vasodilators, in the presence of Hg2+. Hg2+ extraction was realised using ion exchanging resin PUROLITE S920 from the liquid solution used in EC. The results of this study suggests that Hg2+ may be responsible for the aggravation of the endothelial dysfunction found in smoker of EC patients with CAD.

    Abstract: A longitudinal, randomized, five year follow-up clinical and experimental study was conducted during May 1, 2011 - June 30, 2016. A number of 125 eligible postmenopausal women (BMD T-score spine (-2.8 � 0.5)); BMD at the femoral hip (-2.6 � 0.8), treated only with biphosphonates, were enrolled in the study. The patient�s age ranged between 60 and 65 years. All the women were stone formers, with more than five episodes of crystalluria in the last five years. Exclusion criteria: kidney chronic diseases, use of drugs known to affect bone metabolism and renal function, patients with multi-morbidities. The aim of our study was to assess the connection between postmenopausal osteoporosis and the risk of worsening calcium balance in urolithiasis, based on the complex thermogravimetric findings and porosity studies of renal stones eliminated by these patients. The study of renal-urinary concretions offers the possibility to amplify the specific effects of the thermal decomposition processes of substances, reflecting the sample�s global composition. The research of calculi porosity gives information about the dissolution possibilities of the renal-urinary concretions. In conclusion, in postmenopausal women, proper administration of bisphosphonate therapy must accompany the supplementary medication with calcium and vitamin D, always correlated to the metabolic status of the osteoporotic patient.

    Abstract: On a total of 150 renal corrosion casts were examined the posterior branch and the artery of renal posterior segment. For the origin of the posterior branch, there have been highlighted three morphological types, namely: Type I, bifurcation in anterior and posterior branches (92.67% of cases); Type II, trifurcation in anterior, posterior and superior or inferior branches (6.00% of cases); Type III, quadrifurcation in anterior, posterior, superior and inferior branches (1.33% of cases). Depending on the relations between this path and those with the posterior aspect of the renal pelvis, we highlighted four morphological types: Type I (62.67% of cases) with large extension of the posterior segmental artery, convex downward path and multiple subsegmentary branches; Type II (34.00% of cases) with large extension of the posterior segmental artery, that bifurcates or trifurcates in segmental branches and convex downward path; Type III (2.00% of cases) with small extension of the posterior segmental artery, with downward path in relation to the upper portion of the posterior surface of the renal pelvis upper portion; Type IV (1.33% of the cases) with small extension of the posterior segmental artery, with upward trajectory in relation to the lower portion of the renal pelvis. Knowledge of these aspects is important both to investigate morphological imaging and for performing partial resection of the renal parenchyma.
