In <i>Silico</i>Analysis of Cross Reactivity between Lipocalin of Domestic Animals

Open Journal of Immunology 2018年第4期8卷 97-106页

作者： Múnera Marlon Sanchez Andres Sanchez Jorge emiliani yuliana Medical Research Group (GINUMED) Universitary Corporation Rafael Nu&ntilde ez Cartagena Colombia Group of Clinical and Experimental Allergy (GACE) IPS Universitaria University of Antioquia Medellín Colombia

Lipocalins are one of the groups of allergens derived from domestic animals with clinical importance for the development of allergic responses. They have been characterized in different animals. With allergenic capacity characterized, little is known about the epitopes involved in allergic responses. Here, potential antigenic regions involved in cross-reactivity among lipocalins were explored through bioinformatics tools. The amino acid sequences of several lipocalins from different domestic animals (mouse, dog, cat, bull, hamster, horse and pig) were used to determine the degree of kinship by phylogenetic studies. Groups with highest phylogenetic relation were obtained by using MEGA software. 3D models of lipocalins not reported in the protein data bank were modeled by homology to identify potential antigenic regions compromised in the cross-reactivity of this group of allergens. The alignment of the entire database of allergenic lipocalins and the inferred maximum likelihood tree segregate lipocalins into five monophyletic clades (referenced here as A, B, C, D and E). According to the multiple pairing analyzes, group C (Fel d 4, Rat n 1 and Equ c 1) showed the highest degree of identity among their amino acid sequences (58%). The analysis of conserved and exposed residues showed that group C shares three antigenic regions that could potentially contribute to its cross-reactivity. Potential antigenic sites were identified for the generation of cross-reactivity between the different lipocalins analyzed in this study. These studies support the need to carry out directed mutagenesis tests to confirm their relevance in the allergenic capacity of lipocalins.

Transcript Accumulation Dynamics of Phenylpropanoid Pathway Genes in the Maturing Xylem and Phloem of Picea abies during Latewood Formation

引用

Journal of Integrative Plant Biology 2011年第10期53卷 783-799页

作者： Giovanni emiliani Maria Laura Traversi Monica Anichini Guido Giachi Alessio Giovannelli Trees and Timber Institute-National Research Council Department of Chemistry "U.Schiff" University of Florence

In temperate regions, latewood is produced when cambial activity declines with the approach of autumnal dormancy. The understanding of the temporal （cambium activity vs dormancy） and spatial （phloem, cambial region, maturing xylem） regulation of key genes involved in the phenylpropanoid pathway during latewood formation represents a crucial step towards providing new insights into the molecular basis of xylogenesis. In this study, the temporal pattern of transcript accumulation of 12 phenylpropanoid genes （PAL1, C4H315, C4H4, 4CL3, 4CL4, HCT1, C3H3, CCoAOMT1, COMT2, COMT5, CCR2） was analyzed in maturing xylem and phloem of Picea abies during latewood formation. Quantitative reverse transcription-polymerase chain reaction analyses revealed a well-defined RNA accumulation pattern of genes involved in the phenylpropanoid pathway during latewood formation. Differences in the RNA accumulation patterns were detected between the different tissue types analyzed. The results obtained here demonstrated that the molecular processes involved in monolignol biosynthesis are not restricted to the cambial activity timeframe but continued after the end of cambium cell proliferation. Furthermore, since it has been shown that lignification of maturing xylem takes place in late autumn, we argue on the basis of our data that phloem could play a key role in the monoliqnol biosynthesis process.

Flavonols Protect Arabidopsis Plants against UV-B Deleterious Effects

引用

Molecular Plant 2013年第4期6卷 1376-1379页

Dear Editor, Flavonols are synthesized by flavonol synthase （FLS） enzymes （Martens et al., 2010）. These compounds absorb UV-B light in the 280-320-nm region and their concentration increases in plants exposed to environmental abiotic and biotic stresses, including UV-B; consequently, flavonols are thought to act as UV-B filters （Agati et al., 2011）. It has been also suggested that these metabolites function as reactive oxygen species （ROS） scavengers, as they contain an OH- group in the 3-position of the flavonoid skeleton, which allows them to chelate metals, inhibiting the formation of free radicals and ROS accumula- tion, once formed （Agati et al., 2009）. For these reasons, it has been suggested that flavonols play uncharacterized roles in UV responses （Verdan et al., 2011）. Nevertheless, despite the fact that the role of flavonols in UV-B protection has been inferred, the protection conferred by flavonols on the target sites of UV-B-damage has not been directly proven in planta.

文化是一个民族的重要特质和标识,而华文教育正是海外华人文化得以存续和发展的重要途径。印度尼西亚(下称“印尼”)是全球拥有华人最多的国家,同样印尼华人怀着对中华文化的依依之情,在当地创办华文教育,为薪传民族文化不懈奋进。纵观印尼华文教育发展的历史,印尼华文学校经历崎岖泥泞和百转千回的不平凡道路,特别是在印(尼)化运动过程中,印尼华文学校受过不少的打击。今天,随着印尼华文教育的恢复和发展,许多以前被关闭的华文学校也相继复校。它们逐渐从印(尼)化运动的“黑暗中”走出来,往者不可谏,来者犹可追。为了探究“印(尼)化运动”对印尼华文学校带来了哪些影响,本文除了剖析“印(尼)化运动”的缘起、内涵和对华文教育产生的影响,还以印尼八华学校和隆华学校为个案,从师资、课程、生源和存在的问题等方面做了具体的阐释。希望通过本文的写作,让人们了解印尼华文教育的历程和当今发展的现状,尤其是更加重视印尼华文教育的发展前景。

AIM： To analyze the effectiveness of the endoscopic therapy and to identify prognostic factors for recurrent bleeding. METHODS： Retrospective study of patients with gas- trointestinal bleeding secondary to Dieulafoy＇s lesion （DL） from 2005 to 2011. We analyzed the demographic characteristics of the patients, risk factors for gastro- intestinal bleeding, endoscopic findings, characteristics of the endoscopic treatment, and the recurrence of bleeding. We included cases in which endoscopy de- scribed a lesion compatible with Dieulafoy. We exclud- ed patients who had potentially bleeding lesions such as angiodysplasia in other areas or had undergone other gastrointestinal endoscopic procedures. RESULTS： Twenty-nine patients with DL were identi- fied. Most of them were men with an average age of 71.5 years. Fifty-five percent of the patients received antiaggregatory or anticoagulant therapy. The most common location for DL was the stomach （51.7%）. The main type of bleeding was oozing in 65.5% of cases. In 27.6% of cases, there was arterial （spurting） bleeding, and 6.9% of the patients presented with an adherent clot. A single endoscopic treatment was ap- plied to nine patients （31%）, eight of them with adren- aline and one with argon, while 69% of the patients received combined treatment. Six patients （20.7%） presented with recurrent bleeding at a median of 4 d after endoscopy （interquartile range = 97.75）. Within these six patients, the new endoscopic treatment ob- tained a therapeutic success of 100%. The presence of arterial bleeding at endoscopy was associated with a higher recurrence rate for bleeding （50% vs 33.3% for other type of bleeding） rP = 0.024, odds ratio （OR） = 8.5, 95% CI = 1.13-63.87]. The use of combined en- doscopic treatment prevented the recurrence of bleed- ing （10% vs 44.4% of single treatment）（P = 0.034, OR = 0.14, 95% CI = 0.19-0.99）. CONCLUSION： Endoscopic treatment of DL is safe and effective. Adrenaline monotherapy and arterial （spurting） bl

Rotation Thromboelastography for Assessment of Hypercoagulation and Thrombosis in Patients with Cardiovascular Diseases

引用

Journal of Life Sciences 2012年第1期6卷 28-35页

作者： Antoaneta Dimitrova-Karamfilova yuliana Patokova Tania Solarova Irina Petrova Gencho Natchev Clinical Laboratory Univesity Hospital ＂St. Ekaterina ＂＇ Sofia 1431 Bulgaria Department of Cardiac Surgery Univesity Hospital ＂St. Ekaterina ＂ Sofia 1431 Bulgaria

Hypercoagulation is not detected in clinical practice with routinely performed blood coagulation tests. More advanced laboratory analyses to detect or monitor hypercoagulation have not yet been introduced into routine clinical management. Thromboelastography assesses the influence of plasma factors and platelets during all phases of haemostasis, thus permits evaluation of hypo- and hyper- coagulation status. This prospective study included assessment of 35 patients with thrombotic complications （II-nd group）, compared with 34 healthy controls （I-st group）. Haemostasis was analyzed with routine clotting tests： protrombin time （PT）, activated partial thromboplastin time （APTT）, fibrinogen, platelets and rotation thromboelastography （ROTEM~） with measuring time to 20 min. All data are presented as mean and standard deviation （SD）. Statistical comparisons of samples were performed by student＇s t-test. The sensitivity, specificity, positive and negative predictive value of the parameters was calculated by using the receiver operator characteristic （ROC） curves for two groups. There was significant difference （P 〈 0.05） observed in the parameters of ROTEM： clot formation time （CFT）, a-angle, maximum clot firmness （MCF） and thrombodynamic potential index （TPI） in the patient＇s population compared to the healthy controls. No significant difference was observed in CT （ROTEM） and routine coagulation tests when the two groups were compared. Rotation thromboelastography analysis demonstrated to be a reliable method for diagnosis of hypercoagulable state.
