Trichinellosis caused by the Nematode Trichinella is azoonotic disease which occurs worldwide and affects abroad range of different species including mammals, birds and amphibians. Trichinella spiralis is found in production animals (pigs, horses) in temperate climate zones and can also be found in animals in close contact with these production animals (e.g. dogs, cats, rats). The PrioCHECK® Trichinella Ab is a reliable and fast diagnostic test for detection of antibodies against Trichinella in porcine serum and meat juice samples, and can be used for monitoring and surveillance purposes. Keywords: Trichinella, pig, diagnosis, ELISA, Saranda.
旋毛虫病是由旋毛虫引起的一种偶联性疾病,在世界范围内发生,影响到包括哺乳动物、鸟类和两栖动物在内的不同物种。旋毛虫可在温带的生产动物(猪、马)中发现,也可在与这些生产动物密切接触的动物(如狗、猫、老鼠)中发现。PrioCHECK®旋毛虫Ab是检测猪血清和肉汁样品中旋毛虫抗体的可靠和快速诊断测试,可用于监测和监测目的。关键词:旋毛虫,猪,诊断,ELISA,萨兰达

The study called "Shkodra’s turmoil in the Balkan War and the Serbo Montenegrin invasion", sheds light on a period that includes events and important listed facts, seen at national level as well as at local level. This was the reason Shkodra, the largest and the most populated city of Albania, from October 1912 to April 1913 spent the most difficult days in its history, also among the most heroic, especially for the extraordinary resistance in fight for protection from neighboring chauvinists of its territorial integrity. The purpose of the study is a historical overview on the political and social situation, but also wider. It is based mainly on documents from Austro-Hungarian Consulate in Shkodra of the years 1912-1914, as well as in relations from Jesuit priests, who day after day marked events and facts. This study supports the idea that Shkodra, as an integral part of the newly created Albanian state, is primarily a result of the titanic efforts of all Shkodrane without discrimination, which indicated that they were formed as a spiritual family. The world witnessed the common willingness for a civilian national dignity, and desire of living together for the future. On the other hand, it reveals the enormous importance and persistent strong support shown from Austria, in these moments of a severe national trauma. Keywords: Hasan Riza Pasha, The struggle for Scutari, Balcan powers, National movement, Montenegrin occupation, Ottoman commands.Abstract here please not more than 150-200 words
这项名为“巴尔干战争和塞尔维亚-黑山入侵中的斯库德拉混乱”的研究,揭示了一个包括国家层面和地方层面的事件和重要事实在内的时期。这就是为什么从1912年10月到1913年4月,阿尔巴尼亚最大和人口最多的城市斯库德拉度过了其历史上最困难的日子,也是最英勇的日子之一,特别是为了保护其领土完整而与邻国沙文主义者进行了非凡的抵抗。研究的目的是对历史的政治和社会状况进行概述,但也更广泛。它主要基于1912年至1914年奥匈帝国驻斯库德拉领事馆的文件,以及耶稣会牧师的关系,他们日复一日地标记事件和事实。这项研究支持这样一种观点,即作为新成立的阿尔巴尼亚国家的一个组成部分,斯库德拉主要是所有斯库德拉人毫无歧视地作出巨大努力的结果,这表明他们是作为一个精神家庭而形成的。世界见证了对平民民族尊严的共同意愿,以及对共同生活未来的渴望。另一方面,它显示了奥地利在遭受严重民族创伤的时刻所表现出的巨大重要性和持久的强有力支持。关键词:哈桑·里扎·帕夏,斯库塔里之争,巴尔干诸国,民族运动,黑山占领,奥斯曼命令这里的摘要请不要超过150-200字

Background: Lack of vaccination and modern health care facilities in many countries including Albania let meningococcemia to remain as a serious challenging disorder especially among children and in spite of improved diagnosis and earlier treatment its prognosis is still dismal. Patients expected to develop life-threatening complications in acute meningococcal infections require early recognition and appropriate monitoring. Different prognostic scoring systems have been developed. Aim: The aim of this study was to evaluate mortality in children hospitalized with meningococcal infections in Albania, including scoring systems in prognosticating mortality rate. Materials and Methods: This was a retrospective descriptive study, performed on 40 patients with definite diagnosis of meningococcal infection admitted to PICU in UHC “Mother Teresa”, Tirana, Albania, between 2006 and 2014. There were 40 patients, 22(55%) males and 18(45%) females, from 2 months to 10 years old. We evaluated all the patients based on Stiehm and Damrosch and Glasgow meningococcal septicemia prognostic score. Data were collected by filling checklists. SSPS software was applied to analyze the data using chi-square test. Results: Overall mortality was 42%. According to the GMSPS(3) prognostic score of meningococcemia: 28 (70%) patients had a score <8 points and was recorded four deaths representing a mortality rate of 14.2%; the mortality rate among 12(45%) patients with a score ≥8 points resulted in 100% mortality. The sensitivity was 100%, specificity was 100%, the positive predictive value was 100% and the negative predictive value was 100% for a GMSPS score ≥8. According to the Stiehm and Damrosch criteria (2): 22(55%) patients had two or less factors present and was recorded three deaths representing a mortality rate of 13.6%; the mortality rate among 18(45%) patients with three or more factors present the mortality rate was 72.2%. The sensitivity was 90%, specificity was 80%, the positive predictive value was 75% and negative predictive value was 92.3% for the criterion ≥3 of the Stiehm and Damrosch criteria. Conclusions: Meningococci are still killers, they affect men more than women. The Stiehm and Damrosch and Glasgow meningococcal septicemia prognostic score can rapidly identify children with fulminant meningococcal disease and poor prognosis and help us starting prompt administration of suitable antibiotics, critical care and special therapeutic measures. Keywords: Meningococcal disease, meningococcemia, meningitis, children, scoring system.
背景:包括阿尔巴尼亚在内的许多国家缺乏疫苗接种和现代卫生保健设施,使脑膜炎球菌病仍然是一种严重的具有挑战性的疾病,特别是在儿童中,尽管诊断和早期治疗有所改善,但其预后仍然令人沮丧。急性脑膜炎球菌感染患者可能出现危及生命的并发症,需要及早发现并进行适当监测。不同的预后评分系统已经被开发出来。目的:本研究的目的是评估阿尔巴尼亚脑膜炎球菌感染住院儿童的死亡率,包括预测死亡率的评分系统。材料和方法:本研究是一项回顾性描述性研究,对2006年至2014年阿尔巴尼亚地拉那特蕾莎修女UHC PICU收治的40例明确诊断为脑膜炎球菌感染的患者进行研究。40例患者,男22例(55%),女18例(45%),年龄2个月~ 10岁。我们根据Stiehm和Damrosch以及Glasgow脑膜炎球菌败血症预后评分对所有患者进行评估。通过填写核对表收集数据。采用SSPS软件对数据进行卡方检验。结果:总死亡率为42%。根据脑膜炎球菌病的GMSPS(3)预后评分:28(70%)患者评分<8分,记录有4例死亡,死亡率为14.2%;评分≥8分的12例(45%)患者死亡率为100%。对于GMSPS评分≥8分,敏感性为100%,特异性为100%,阳性预测值为100%,阴性预测值为100%。根据Stiehm和Damrosch标准(2):22例(55%)患者存在两种或更少的因素,记录有3例死亡,死亡率为13.6%;有3种及以上因素的18例(45%)患者的死亡率为72.2%。Stiehm和Damrosch标准≥3项的敏感性为90%,特异性为80%,阳性预测值为75%,阴性预测值为92.3%。结论:脑膜炎球菌仍是致命疾病,男性多于女性。Stiehm和Damrosch以及Glasgow脑膜炎球菌败血症预后评分可以快速识别患有暴发性脑膜炎球菌病和预后不良的儿童,并帮助我们开始及时给予适当的抗生素、重症监护和特殊治疗措施。关键词:脑膜炎球菌病,脑膜炎球菌血症,脑膜炎,儿童,评分系统。

Trichinellosis (also trichinosis) in animals is caused by nematodes (roundworms) of the family Trichinellidae Ward, 1970. Family characteristics. Parasites with small bud right body. They have not sexual pterygas. The anus is opened at the terminal part of body . The cloaks are opened at the ¼ frontal part of the body. The adult females are larva-productive. They are parasites of intestinal system. Trichinella spiralis (Trichina spiralis) Owen, 1833. Eight species of Trichinella are now recognize, based on host (Kapel, C M O 2000; Krivokapich, S J; Pozio E and D S Zarlenga, 2005; Pozio E et al, 1992), but the most important for animals domestic are: T. spiralis found as parasitic diseases on humans, pigs, rodents, and many carnivorous animals, of Europe, Asia, North America, with specific pathologies in pigs. T. nativae parasite of wild carnivorous of Euro – Asiatic areas norther of parallel 40°. It is specific diseases of carnivorous and omnivorous animals. T.nelsoni found as parasite of wilds carnivorous animals of Asiatic areas southern of parallel 40°. T. pseudospiralis is parasite of cats, rodents and pigs. It is recognized from other species because of the adult forms have smaller dimensions and forms non capsulated cists. T. spiralis is the cause of Trichinellosis, one of most important zoonosis allover the world. It is found worldwide in many carnivorous and omnivorous animals, insectivorous animals, rodents, wilds animals and humans (Pozio E and G Marucci 2003). It was found at 103 mammals. Occasionally may be found as parasite of horses. Developmental traits of T. spiralis is that infested hosts initially are final hosts because of they host adults forms at their intestine, but later on they are presented as intermediate host, because of they host larval forms at their muscles. Today’s identification of samples to the species level and genotyping are based primarily upon molecular means (Pozio, E., and G. Marucci. 2003). Keywords: trichinosis, Trichinella larvae, tropism, trichinelloscopic examination, trypsine techniques, xenodiagnostic experiments, etc.
动物中的旋毛虫病(也称旋毛虫病)是由Ward, 1970年的旋毛虫科线虫(蛔虫)引起的。家庭的特点。右体有小芽的寄生虫。它们没有性器官。肛门在身体的末端打开。斗篷在身体的前部打开。成年雌蚊产卵能力强。它们是肠道系统的寄生虫。旋毛虫(Trichinella spiralis)欧文,1833。根据宿主,目前已确认有8种旋毛虫(Kapel, C M O 2000;Krivokapich, S J;Pozio E and D S Zarlenga, 2005;Pozio E et al, 1992),但对家养动物最重要的是:在欧洲、亚洲和北美的人类、猪、啮齿动物和许多食肉动物身上发现的螺旋体绦虫是一种寄生虫病,在猪身上有特定的病理。东经40°以北的欧亚地区野生食肉动物的本地寄生虫。它是肉食性和杂食性动物特有的疾病。在亚洲地区平行40°以南的野生肉食性动物中发现的寄生虫。假螺旋绦虫是猫、啮齿动物和猪的寄生虫。它是从其他物种中识别出来的,因为成年形式具有较小的尺寸和形式无包囊囊。旋毛虫病是世界上最重要的人畜共患病之一。它在世界范围内的许多肉食性和杂食性动物、食虫动物、啮齿动物、野生动物和人类中都有发现(Pozio E和G Marucci 2003)。在103种哺乳动物中发现了这种病毒。偶尔可以在马身上发现寄生虫。螺旋螺旋体的发育特征是,被侵染的寄主最初是最终寄主,因为它们在肠道中寄主成虫,但后来它们作为中间寄主出现,因为它们在肌肉中寄主幼虫。今天对物种水平的样本鉴定和基因分型主要基于分子手段(Pozio, E.和G. Marucci. 2003)。关键词:旋毛虫病,旋毛虫幼虫,趋向性,旋毛虫镜检查,胰蛋白酶技术,异种诊断实验等

Background: Distinguishing glial subtypesbased on nuclear and cellular morphology alone is subjective,with significant interobserver variability, even among highlyexperienced neuropathologists. Geneticsubtyping of a given histological phenotype and robust biomarkershas improved the diagnostic and prognostic assessment. Recently, IDH1 (more rarely IDH2) mutations have been found in nearly 40% of gliomas and strongly predict lower grade in histology and better outcomes. Aim: To evaluate if expression of alpha-internexin (INA) can be used a reliable diagnostic, prognostic and cost-effectivemarker, a proneural gene-coding neurofilament interacting protein significantly correlated with oligodendroglial phenotype, 1p/19q codeletion as well as higher chemosensitivity and better prognosis to our study population. Matherial: We studied INA expression in 137gliomasand correlated it with pure oligodentroglialhistology, IDH1, p53, EGFR and SYN expression by immunohystochemestry.Results: INA was expressed in 72.2% of grade II oligodendrogliomas (n = 22), 62.5% of grade III oligodendrogliomas (n = 16), 57.2% of grade II oligoastrocytomas (n = 7), 66.7% of grade III oligoastrocytomas (n = 6), 66.7% of glioblastomas with oligodendroglial component (n = 12), 0% of grade I astrocytomas (n = 13), 0% of grade II astrocytomas (n = 4), 0% of grade III astrocytomas (n = 12) and 2.5% of glioblastomas and gliosarcomas (n = 40).INA was expressed by 27(71.1%) of pure oligodentrogliomas(n=38) versus 17(17.2%) of non pureoligodentrogliomas(n=99),Chi square was p < 10-4; Cramer’s V was 0.517; p <10-4, which show a very strong relationship.INA was expressed by 32(45.1%) of gliomas with IDH1 mutation (n=71) versus 12(18.2%) of gliomas without IDH1 mutation (n=66), Chi square was p < 0.001; Cramer’s V was 0.288; p < 0.001, which show a very strong relationship. INA was expressed by 26(27.4%) of gliomas with P53 mutation (n=95) versus 18(42.9%) of gliomas without P53 mutation (n=42), Chi square wasp=0.05 which show they were negatively correlated. INA was expressed by 30(50.0%) of gliomas with SYN expression (n=60) versus 14(18.2%) of gliomas without SYN expression (n=77), Chi square was p < 10-4; Cramer’s V was 0.338; p < 10-4, which show a very strong relationship. INA was expressed by 12(27.3%) of gliomas with EGFR expression (n = 44) versus 32(34.%) of gliomas without EGFR expression (n=44), Chi square was p=0.05 which show they were negatively correlated. Conclusion: INA expression is a fast, cheap and reliable diagnostic and prognostic marker, which helpsindentify patients of different prognostic groups in diffuse gliomas and should be used routinely in the pathologic diagnosis of glial tumours.

The First Works of Albanian Ballet 阿尔巴尼亚芭蕾舞团首部作品
Pub Date : 2016-02-04 DOI: 10.0001/(aj).v5i1.750
Roberta Ndokaj
The article, “Beginnings of Albanian Ballet”, sheds light on the choreographic elements of the three national ballets: “Anusha”, “Halili and Hajria” and “Highland Maiden”, composed in the 60s. The first is treasured as the earliest composition in the chronology of the art, the second as the first complete ballet with an elaborate concept of form and high artistic values, whereas the third as a ballet that introduced innovations in artistic composition through the interweaving of elements of traditional and contemporary ballet. Although they are products of the social realism movement, in which, from our modern point of view, the restrictions of the times emerge, they also demonstrate a new artistic level, as well as an important stage in the development of the art of ballet as an original national art form. The talent and creative control of Albanian composers, librettists, choreographers and ballet dancers was confirmed in these ballets, which, along with their interesting subject matter, beautiful music composed of authentic Albanian motifs, offered beautifully choreographed numbers, which harmonized the vocabulary of classical ballet with other modes and forms of expression originating from the abundant Albanian tradition of dance, thus creating a unique and interesting new style. These ballets laid the foundations for the further development of authentic Albanian ballet, thus enriching the burgeoning art form, which had been established with great efforts, talent, dedication and love. Keywords: ballet, choreography, artistic, tool, national, dance, performance, dancer, classical, subject, truth, vocabulary.
这篇题为“阿尔巴尼亚芭蕾舞的起源”的文章,揭示了三部国家芭蕾舞剧的编舞元素:《阿努沙》、《哈利利和哈伊里亚》和《高地少女》,创作于60年代。第一部被认为是艺术编年史上最早的作品,第二部被认为是第一部完整的芭蕾舞剧,具有精致的形式概念和很高的艺术价值,而第三部被认为是通过传统和现代芭蕾元素的交织在艺术构图上进行创新的芭蕾舞剧。虽然它们是社会现实主义运动的产物,从我们现代的角度来看,这些运动中出现了时代的限制,但它们也展示了新的艺术水平,也是芭蕾舞艺术作为一种原始的民族艺术形式发展的重要阶段。阿尔巴尼亚作曲家、剧作家、编舞家和芭蕾舞演员的才华和创造力在这些芭蕾舞剧中得到了证实,这些芭蕾舞剧除了有趣的主题、由真正的阿尔巴尼亚主题组成的优美音乐之外,还提供了优美的舞蹈编排,将古典芭蕾的词汇与源于丰富的阿尔巴尼亚舞蹈传统的其他模式和表达形式相协调,从而创造了一种独特而有趣的新风格。这些芭蕾舞为真正的阿尔巴尼亚芭蕾舞的进一步发展奠定了基础,从而丰富了这一新兴的艺术形式,这一艺术形式是用巨大的努力、才华、奉献和热爱建立起来的。关键词:芭蕾,编舞,艺术,工具,民族,舞蹈,表演,舞者,古典,主题,真理,词汇。

ZnO nanorod has been successfully synthesized through the reduction of Zinc chloride salt with ammonia solution in the presence of triethanolamine (TEA) as surfactant agent via hydrothermal technique. The properties of the produced material were determined using different characterization techniques such as X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and Fourier Transform Infrared spectrum (FTIR). The results showed that the asprepared ZnO are rod- like morphologies at pH equal to 10. The synthesized nano rod-zinc oxide was employed as adsorbent agent for basic yellow 28 dye decolorization from polluted industrial wastewater. The synthesized nano-ZnO was achieved 93.26% dye decolorization affinity with in 60minutes. The variation in the different processing parameters on the dye sorption process was elucidated using batch technique. The increment in both the dye solution pH and its temperature was association with decline in the decolourization process. The optimum nano-zinc oxide dosage was recorded to be equal to 10 g/L. The adsorption data at equilibrium were analyzed using Langmuir, Freundlich and Temkin equilibrium isotherms. The experimental results confirmed the applicability of synthesized nano-zinc oxide as adsorbent agent for dye decontamination from polluted wastewater. Keywords: nano-zinc oxide, dye decolourization, sorption parameters.
以三乙醇胺(TEA)为表面活性剂,采用水热法,以氨水还原氯化锌盐,成功合成了氧化锌纳米棒。利用x射线粉末衍射(XRD)、扫描电子显微镜(SEM)和傅里叶变换红外光谱(FTIR)等不同的表征技术对所制备材料的性能进行了测定。结果表明:制备的ZnO在pH = 10时呈棒状。采用合成的纳米棒氧化锌作为吸附剂对工业废水中的碱性黄28染料进行脱色。合成的纳米zno在60min内的染料脱色亲和度达到93.26%。采用间歇法研究了不同工艺参数对染料吸附过程的影响。染料溶液pH和温度的增加与脱色过程的下降有关。纳米氧化锌的最佳用量为10 g/L。采用Langmuir、Freundlich和Temkin平衡等温线分析了平衡吸附数据。实验结果证实了合成的纳米氧化锌作为吸附剂用于废水染料净化的适用性。关键词:纳米氧化锌,染料脱色,吸附参数。

Biochemical and Physiological Biomarkers in Aquatic Environmental Research 水生环境研究中的生化和生理生物标志物
Pub Date : 2016-01-08 DOI: 10.0001/(AJ).V3I0.726
A. Osman
Biomarkers are used as tools to assess biological changes that may reveal exposure of organisms to environmental chemicals. In some cases, biomarkers are able to indicate that chemicals specifically affect metabolic pathways or physiological functions in exposed individuals. Therefore, biomarkers can be used as both diagnostic and predictive tools. More recently, the concept of “biomarkers” has gained popularity amongst environmental managers. There are many different biomarkers that occur at many different levels of organization from sub-cellular to wholeorganisms. Biomarkers at the molecular level tend to respond first, followed by responses at the cellular (biochemical and physiological), and whole-body levels. within this review, I will review the application of some biochemical and physiological biomarkers in aquatic environmental research. This review presents a synthesis of the state of the art in the methodology of biochemical and physiological biomarkers and its contribution in aquatic environmental research. The text explores the latest knowledge and thinking on this very important approach for the assessment of environmental health, management, and conservation. The primary concern of the present review is the measurement of biomarkers in aquatic organisms under field and laboratory conditions, where effects of chemicals at different levels of biological organization can be examined. Keywords: Biomarkers, aquatic organisms, biochemical biomarkers, physiological biomarkers
生物标志物被用作评估可能揭示生物体暴露于环境化学物质的生物变化的工具。在某些情况下,生物标志物能够表明化学物质特异性地影响暴露个体的代谢途径或生理功能。因此,生物标志物既可以作为诊断工具,也可以作为预测工具。最近,“生物标志物”的概念在环境管理者中越来越受欢迎。从亚细胞到整个生物体,有许多不同的生物标志物出现在许多不同的组织水平上。分子水平上的生物标志物往往首先反应,其次是细胞(生化和生理)和全身水平的反应。本文就生物化学和生理标志物在水生环境研究中的应用作一综述。本文综述了生物化学和生理生物标志物方法的最新进展及其在水生环境研究中的贡献。本文探讨了对环境健康、管理和保护的评估这一非常重要的方法的最新知识和思想。本综述主要关注的是在野外和实验室条件下水生生物中生物标志物的测量,在这些条件下可以检查化学物质在不同生物组织水平上的影响。关键词:生物标志物,水生生物,生化生物标志物,生理生物标志物
