We consider the space of rapidly decreasing sequences s and the derivative operator D defined on it. The object of this article is to study the equivalence of a differential operator of infinite order; that is φ（D） =^∞∑k=0φkD^k.φk constant numbers an a power of ***, meaning, is there a isomorphism X （from s onto s） such that Xφ（D） = D^nX？. We prove that if φ（D） is equivalent to Dn, then φ（D） is of finite order, in fact a polynomial of degree n. The question of the equivalence of two differential operators of finite order in the space s is addressed too and solved completely when n = 1.

jatropha curcas is a species with a variety of uses. It is grown primarily for oil for biodiesel, but also has agronomic and medicinal applications. Two methods were evaluated for cryopreservation of seeds and zygotic embryos of j. curcas: desiccation followed by rapid immersion of seeds and embryos in liquid nitrogen (LN, -196°C), and vitrification of zygotic embryos. Prior to cryo-preservation, seeds were manually scarified and the moisture content (MC) of seeds and embryos was determined. Explants were disinfected after cryopreservation. Seed germination after LN exposure was 100%. Plantlet development was better in sand substrate than that in vitro. Survival of zygotic embryos after cryopreservation was also 100%, without significant differences between treatments. Optimal development (100%) and plantlet length (51.77 mm) were observed with embryos dried for 60 min to 9.4% MC under laminar flow prior to cryopreservation. Zygotic embryos subjected to the vitrification procedure did not withstand LN exposure. Survival data for non-cryopreserved embryos after each step of the vitrification procedure provided information about embryo tolerance to cryoprotectants.

Introduction: Left Ventricle Postinfarction Pseudoaneurysm (LVPS)—false aneurysm occurs after a free-wall rupture contained by the adjacent pericardium. LVPS lacks the normal structure of the ventricular wall and disrupts the normal chamber anatomy. However, the natural history, clinical presentation and surgical outcome are still unclear. For that reason, it is necessary to describe the most relevant anatomical characteristics of LVPS and the appropriate surgical strategies currently applied. Methods: We reviewed the anatomical characteristics of several patients diagnosed of LVPS and the surgical technique performed. In this work two different anatomical types of LVPS are described in detail, with the surgical and structural implications for left ventricle reconstruction. Results: There are two different anatomical forms of LVPS: 1) Typical pseudoaneurysm, with a small gateway neck between the Left Ventricle and the false aneurysm chamber (Figure 1(A));2) Atypical pseudoaneurysm, in which the anatomical defect is bigger, without well-defined edges, extends over a large segment of infarcted and thinned myocardial tissue. In both cases, the therapeutics targets and the surgical techniques used were directed to restore the normal geometry of Left Ventricle, keeping the optimal mitral valve function. Conclusions: The surgical key-step is to preserve or to remodel the ventricular chamber anatomy. This fact restores the ventricular geometry, not only removing the wall discontinuity that generated the pseudoaneurysm. Nevertheless, final prognosis depends on the underlying ischemic cardiomyopathy and mechanical complications, such us mitral regurgitation or ventricular septal defect.

The translation of the genotype into phenotype, represented for example by the expression of genes encod- ing enzymes required for the biosynthesis of phytochemicals that are important for interaction of plants with the environment, is largely carried out by transcription factors （TFs） that recognize specific cis-regulatory elements in the genes that they control. TFs and their target genes are organized in gene regulatory net- works （GRNs）, and thus uncovering GRN architecture presents an important biological challenge necessary to explain gene regulation. Linking TFs to the genes they control, central to understanding GRNs, can be car- ried out using gene- or TF-centered approaches. In this study, we employed a gene-centered approach uti- lizing the yeast one-hybrid assay to generate a network of protein-DNA interactions that participate in the transcriptional control of genes involved in the biosynthesis of maize phenolic compounds including gen- eral phenylpropanoids, lignins, and flavonoids. We identified 1100 protein-DNA interactions involving 54 phenolic gene promoters and 568 TFs. A set of 11 TFs recognized 10 or more promoters, suggesting a role in coordinating pathway gene expression. The integration of the gene-centered network with informa- tion derived from TF-centered approaches provides a foundation for a phenolics GRN characterized by in- terlaced feed-forward loops that link developmental regulators with biosynthetic genes.

Oral hyperpigmentation is a common event in older individuals, however, is exceptional in neonates (congenital melanotic macules). Conversely, 70- 80% of people have sebaceous glands in the oral mucosa, with the tongue representing an ectopic location and termed sebaceous choristoma by some authors. We report a case that fulfills both conditions in a tongue lesion. A 1-month-old boy presented with a pigmented macula on his tongue noted at birth. An excisional biopsy was performed showing a lesion lined by an epidermal-like epithelium with basal pigmentation, under which, sebaceous glands, abortive hair follicles and ductal structures mimicking apocrine glands were found. Seven cases of congenital melanotic macules of the tongue have been reported, however, none of them showed sebaceous glands under the lesion. Furthermore, there has not been a reported case of sebaceous choristoma of the tongue present at birth. We present a case that shares clinical and histological features of both conditions and propose the name ‘ epidermal choristoma’ .

提出了钢筋混凝土和预应力混凝土承受组合荷载下的分析模型,荷载包括轴力、双向弯矩、扭矩和双向剪力。所提出的模型基于Timoshenko梁理论的简单动力假设,保持了任意截面尺寸情况下的三维框架的形状。框架的控制截面被细分为一维,二维和三维材料响应。钢筋混凝土和预应力混凝土构建的材料模型遵循用切线刚度公式表示的改进压缩场理论的基本假设。通过其结果与文献中几个著名的试验相比较验证了模型的正确性。这些模拟包括弯曲、剪力和扭矩一系列变化的荷载组合。分析结果显示,试件的极限强度以及从初始裂缝到最终荷载的局部应变响应与试验结果十分吻合。
