Pseudoaneurisms are arterial wounds that affect all layers of an artery;although very rare they are mostly lethal and most of them are iatrogenic. Herein, we present two different cases of hepatic artery pseudoaneurysms derived from previous surgeries which were assessed by computed tomography angiographies and consequent conservative endovascular approaches with arteriographies, posterior cannulations and the placement of Amplatzer Vascular Plug 4 (AVP 4) systems in order to treat the pseudoaneurysm. Computed control tomographies were conducted showing no later complications. The purpose of this article is to demonstrate the importance and current clinical applications of AVP in the field of interventional radiology.

本文报道分析了固体腐植酸颗粒在不同条件下的分解动力学。在pH值为4和5时,分解速率非常小,达到平衡需要若干年的时间。这一速率非常明显地随pH的增加而增大,在pH=11时,在30min内就能完全分解。在单羧酸和阴离子除草剂如草甘膦和2,4-D存在时,分解速率显著增加。相反,在无机二价阳离子(Mg,Ca,Sr,Ba)存在时,速率减小。而二价阳离子百草枯具有双重效应,在pH>7时减小分解速率,在pH<7时增加分解速率。一个假定表面控制的分解动力学的简单模型可以合理再现阴阳离子的效应。不同离子通过调节位于颗粒表面的HA分子之间的相互作用力来影响分解速率。

Flowering is essential in any breeding programme, particularly in genetic introgression programmes in which flowering synchronism is required. In this work, 16 sugarcane genotypes were evaluated using three different flowering-inductive photoperiod treatments (30 s, 45 s, and 1 min of a daily photoperiod decrease from 12 h 55 of light). Each genotype was planted in 43 L pots (equal proportion of soil, sand, and substrate) with three tillers per pot. Plants with 4 to 6 internodes were placed in a photoperiod facility with three controlled chambers, each chamber containing all 16 genotypes (one treatment per chamber). The temperature range (21°C to 32°C) and humidity were the same for all of the treatments. The flower induction started in September 2010 and ended in April 2011. The plant elongation and flag leaf and inflorescence emergence were recorded and the pollen viability was evaluated by using the iodine staining method. The photoperiod facility provided suitable conditions for flowering, as the plants in the three treatments successfully flowered. The genotypes in the three treatments behaved differently in relation to the date of panicle emergence, with the treatment of 45 s showing better results. The results here presented contribute to synchronise flowering for desired sugarcane crosses, particularly those from introgression programmes between commercial cultivars and species from the Saccharum complex.

A gram-positive, rod-shaped, aerobic, thermo-acidophilic bacterium CC2 （optimal temperature 55℃ and pH 4.0）, belonging to the genus Alicyclobacillus was isolated from geothermal soil collected from ＂Cerro Caliente＂, Deception Island, Antarctica. Owing to the harsh environmental conditions found in this territory, microorganisms are exposed to conditions that trigger the generation of reactive oxygen species （ROS）. They must have an effective antioxidant defense system to deal with this oxidative stress. We focused on one of the most important enzymes： superoxide dismutase, which was partially purified and characterized. This study presents the first report of a thermo-acidophilic bacterium isolated from Deception lsland with a thermostable superoxide dismutase （SOD）.
