Effects of an Anatoxin-a(s)-Producing Strain of Anabaena spiroides(Cyanobacteria)on the Survivorship and Somatic Growth of Two Daphnia similis Clones

引用

Journal of Environmental Protection 2013年第6期4卷 12-18页

The toxicity of an anatoxin-a(s) producer strain of Anabaena spiroides (ITEP-024) was estimated through sub-chronic bioassays with two clones of Daphnia similis (Labtox and Itajubá), both with intact cells and aqueous extracts of lyophilized material. Animals were grown as clonal cultures in the lab with mineral water plus 20% lake water. The concentrations used in the bioassays were 0.125, 0.25, 0.375, 0.50 and 1.00 mg·L-1 for intact cell cultures and 10, 25, 50 and 100 mg·L-1 for aqueous extracts. Controls with nutritive food were used. The bioassays lasted 72 hours for the aqueous extracts and 96 hours for the intact cell cultures, with measurements of survivorship every day and body length at the beginning and at the end of the bioassays. Both kinds of samples affected survivorship and growth rate of both Daphnia clones, with the intact cell samples being more effective than aqueous extracts. Regarding survivorship, the clone Itajubá was more sensitive to aqueous extracts than the clone Labtox (LC50 = 54.4 and 83.1 mg·L-1, respectively). No significant difference was found between clones in the intact cell bioassays. Regarding growth rates, a significant difference was found between clones in both samples. However, growth rate was significantly decreased in much lower concentrations of intact cells than in aqueous extracts of cyanobacteria. A stimulus of growth was found in the lower concentration (10 mg·L-1) of aqueous extracts, which is consistent with a hormetic response. In spite of its known high neurotoxicity to mice, ITEP-024 strain caused any effect on mobility of both clones. The effects on survivorship and growth of Daphnia caused by ITEP-024 strain in much higher concentrations of aqueous extracts suggests that uptake of toxins from the water are not so effective as the uptake trough the gut when intact cells are ingested.

Trimetazidine and Cellular Response in Cardiopulmonary Bypass

引用

World Journal of Cardiovascular Surgery 2013年第5期3卷 171-179页

作者： Gerez Fernandes Martins Aristarco G.de Siqueira Filho Joao Bosco de F.Santos Claudio Roberto Cavalcanti Assuncao Alberto Valencia Gerez Martins Cardiac Surgery department Institute of Cardiology State Aloysio de CastroRio de JaneiroBrasil Cardiology department Federal University of Rio de JaneiroRio de JaneiroBrasil

Background: Organic cellular inflammatory response constitutes a pathophysiological mechanism present in all Coronary Artery Bypass Graftings (CABGs). In this aspect, the organism brings forth its defenses through answers that involve cellular components. Objectives: To evaluate, in a randomized double-blind prospective study, controlled with placebo, the effects of trimetazidine (Tmz) on cellular response, analyzed through the variation of leukocytes, neutrophils and monocytes. Patients and Method: 30 patients were randomly selected to be studied, with no more than a mild ventricular dysfunction, and divided into two groups (Tmz and placebo) stratified by echocardiography and receiving medication/placebo in a 60 mg/day dose. The samples of leukocytes, neutrophils and monocytes were obtained in the pre-operatory day without medication, at surgery day with 12 to 15 days of medication/placebo, with 5 minutes after the aortic declamping, and within 12, 24 and 48 hours after surgery. Results: The leukocytes and neutrophils levels have decreased significantly in the treated group when compared to the control group, in all analyzed moments (p = 0.012;p = 0.005). Conclusions and Clinical Implications: Trimetazidine has proved to reduce significantly the levels of total leukocytes and neutrophils in patients submitted to CABG.

Cardiac Perforation by Firearm:Case Report

World Journal of Cardiovascular Surgery 2018年第10期8卷 189-195页

Heart trauma caused by a firearm projectile is the most fatal of cardiac injuries due to the great potential for death. The increase in the number of cases in recent years is observed, due to the greater urban violence. We report the case of a patient, a victim of firearm perforation, who suffered a cardiac transfixing lesion, with clinical presentation and with an unusual cardiac injury, operated at our service with success.
