This paper provides an overview of nanocomposite organic electron beam (EB) resist polymers from the viewpoint of advanced techniques for biology and medicine. An outstanding issue with organic devices is the difficulty of simultaneously controlling the lateral size and position of structures at submicron or nanometer scales. Nanocomposite EB organic resist of ZEP520a containing [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) is an excellent electrically conductive material for nanometer lateral-scale organic electronic devices. The distribution of PCBM aggregations in the nanocomposite is examined. The results open the door to the simple fabrication of densely integrated sensitive biosensors with electrical nanowires and single-electron transistors for multiplexed and simultaneous diagnoses.

A widely used associative learning technique for biological studies involves introducing Drosophila larvae to two different odorants and associating one of the odorants with a stimulus. The experimental method requires transferring the larvae back and forth between two odor chambers. Each chamber contains a different odorant and one of the chambers contains an accompanying stimulus. By introducing the larvae to the two different odorants several times, the larvae are trained to commit the odorant associated with the stimulus to memory. We created a mechatronic system for transporting Drosophila larvae back and forth between two agar trays to reduce manual labor and enable a scalable platform for associative learning and related studies. Air was chosen as the means of transporting the larvae and a chamber was constructed for housing the two agar trays. Control electronics were implemented for creating a sweeping blowing motion to transport the larvae in a gentle manner. Computer aided design (CAD) software was employed in conjunction with a 3D printer to build nozzles which help to direct airflow. Flow analysis software was utilized to model computational fluid dynamic simulations for optimizing air nozzles. In this study, a pneumatic transport system was developed and tested. The experimental results showed a 90% success rate for the transportation of larval Drosophila across the chamber and an overall decrease in transportation time by 4.8 times compared to manual transportation.
在生物学研究中,一种广泛使用的联想学习技术是将果蝇幼虫引入两种不同的气味,并将其中一种气味与刺激联系起来。实验方法需要将幼虫在两个气味室之间来回转移。每个房间包含不同的气味,其中一个房间包含伴随的刺激。通过多次向幼虫引入两种不同的气味,幼虫被训练成将与刺激相关的气味记忆。我们创建了一个机电系统,用于在两个琼脂托盘之间来回运输果蝇幼虫,以减少人工劳动,并为联想学习和相关研究提供可扩展的平台。选择空气作为运输幼虫的手段,并建造了一个容纳两个琼脂盘的室。控制电子装置用于创建一个扫吹运动,以温和的方式运输幼虫。计算机辅助设计(CAD)软件与3D打印机结合使用来构建有助于引导气流的喷嘴。利用流动分析软件建立计算流体动力学模型,对空气喷嘴进行优化。在本研究中,开发并测试了一种气动输送系统。实验结果表明,果蝇幼虫的运输成功率为90%,运输时间比人工运输减少了4.8倍。

Introduction: Workers who work in salvage plant industry are at risk of exposure to aluminum (Al). The objective of this study was to conduct a longitudinal quantitative health risk and bio monitoring assessment for workers exposed to Al. Methods: Al workers were compared to controls. A standardized medical examination and neurobehavioral tests and pulmonary assessment were achieved. The longitudinal study was based on repeated measurements (Airborne and urine Al evaluations). Results: Clinical results showed no evident adverse effects, only mild health impairings. Modification of industrial process to reduce Al exposure leaded paradoxically to increase Al peaks in airborne and urine samples. Conclusion: Hygienic and architectural measures taken to improve exposure and to reduce Al inhalation was a failure. Appropriate preventive measures should be carefully assessed before being applied to protect effectively exposed workers.

In this study, the detection limit sensitivity to the level of μg L-1 was achieved. For this, by applying AuNPs signal fluctuations of high sensitivity was carefully monitored so that they become measureable with highest possible precision. The proposed method is capable of determining TTA over a range of 10-100 μgL-1 with a limit of detection 5 μg L-1. The relative standard deviation of the method was 3% and 1.5%. The obtained preliminary results from this study proved to be effectively successful in determination of TTA in water. A comparison between the proposed method and the previously published methods for TTA determination has also been made for the first time.

Outbreaks caused by foodborne microbes pose serious public health and food safety concerns worldwide. There is a great demand for rapid, sensitive and high-throughput methods to detect and track these pathogens in food, water and other environments. Recent advances in DNA genomic technology have enabled high-throughput analyses of strains by capturing total genomic content of strains and with concomitant comparative phylogenies. Microarrays are particularly adept for distilling large amounts of genomic DNA sequence information such as the gene(s) or genetic traits of hundreds of foodborne isolates in a single experiment. Hence, over the past two decades, microarray technology has advanced tremendously due to accessibility to thousands of complete and draft microbial genomes and this progress has led to the design and manufacturing of newer microarrays which can now identify gene sequence variations down to a single nucleotide polymorphism. DNA microarray remains a useful tool for rapid and refined genomic analysis of foodborne microbes. In this review, we will primarily focus our discussion on pathogen detection, serotype identification and tracking the genetic diversity and source of contamination of respective foodborne strains with our first-hand experience in using this technology.
由食源性微生物引起的疫情在全世界引起了严重的公共卫生和食品安全问题。人们迫切需要快速、灵敏和高通量的方法来检测和跟踪食物、水和其他环境中的这些病原体。DNA基因组技术的最新进展使菌株的高通量分析成为可能,通过捕获菌株的总基因组含量并伴随比较系统发育。微阵列特别擅长于在一次实验中提取大量基因组DNA序列信息,如数百种食源性分离物的基因或遗传特征。因此,在过去的二十年中,由于可以获得数千个完整的微生物基因组,微阵列技术已经取得了巨大的进步,这一进步导致了新的微阵列的设计和制造,现在可以识别基因序列变异到单核苷酸多态性。DNA微阵列仍然是一种有用的工具,用于快速和精细的食源性微生物基因组分析。在这篇综述中,我们将主要集中讨论病原体检测、血清型鉴定和跟踪各自食源性菌株的遗传多样性和污染源,并结合我们使用该技术的第一手经验。

Why is Lamin B Receptor Downregulated in Senescence 为什么纤层蛋白B受体在衰老过程中下调

An important mechanism ensuring spatial organization of chromatin structure and genome function in eukaryotic nuclei consists in anchoring of specific heterochromatin regions to nuclear envelope by proteins of inner nuclear membrane (INM) that are able to recognize these regions and simultaneously bind either Lamin A/C or lamin B1. One of these proteins is lamin B receptor (LBR) that binds lamin B1 and tethers heterochromatin to INM in embryonic and undifferentiated cells. It is replaced by lamin A/C with specific lamin A/C binding proteins (especially LEM-domain proteins) at the beginning of cell differentiation. Our functional experiments in cancer cell lines show that heterochromatin in cancer cells is tethered to INM by LBR that is downregulated together with lamin B1 at the onset of cell transition to senescence. A coordinated regulation of these proteins is evidenced also by downregulation of LB1 in cells with LBR silenced by shRNA. The downregulation of these proteins in senescent cells leads to the detachment of centromeric heterochromatin from INM resulting in it distension in nucleoplasm. These changes in structure of constitutive heterochromatin may be the reason of a permanent loss of cell proliferation in senescence.
真核生物细胞核中染色质结构的空间组织和基因组功能的重要机制是通过核膜内蛋白(INM)将特定的异染色质区域锚定在核膜上,这些蛋白能够识别这些区域并同时结合Lamin A/C或Lamin B1。其中一种蛋白质是层粘连蛋白B受体(LBR),它在胚胎和未分化细胞中结合层粘连蛋白B1并将异染色质系在INM上。在细胞分化初期,它被特定的lamin A/C结合蛋白(尤其是lem结构域蛋白)取代。我们在癌细胞系中进行的功能实验表明,癌细胞中的异染色质通过LBR连接到INM,在细胞向衰老转变的开始,LBR与层合蛋白B1一起下调。在LBR被shRNA沉默的细胞中,LB1的下调也证明了这些蛋白的协调调节。衰老细胞中这些蛋白的下调导致着丝粒异染色质脱离INM,导致其在核质中膨胀。这些组成异染色质结构的变化可能是衰老过程中细胞增殖永久性丧失的原因。

Neuron driven physiological activities such as sleep, feeding, energy consumption are controlled by light sensitive central clock genes in the pacemaker neurons in the brain. Multiple epigenetic events including post-transcriptional regulation, splicing, polyadenylation, mature mRNA editing and stability of translation products are the main vibrators for circadian oscillation with the instructive role of various sets of non-coding small regulatory RNA. Here, we sum up the basic role of small regulatory RNA and their epigenetic circuits in brain clock activity.

AIRE Gene Mutation in Chinese APS-1 Patients 中国APS-1患者AIRE基因突变
Pub Date : 2017-08-03 DOI: 10.4172/2379-1764.1000235

Autoimmune polyendocrine syndrome type 1 (APS-1, OMIM 2403000) is a rare autosomal recessive disease that is caused by autoimmune regulator (AIRE) gene. The main symptoms of APS-1 are chronic mucocutaneous candidiasis, autoimmune adrenocortical insufficiency (Addison’s disease) and hypoparathyroidism. To date, more than 100 different mutations of the AIRE gene have been identified in APS-1 patients. These different mutations affect the structure and function of the AIRE protein in different ways, which eventually leads to the development of APS-1. So far, only five cases of APS-1 have been reported in the Chinese, and the main mutation sites are c. 769C>T (p.R257*), c.55G>A (p.A19T), c.463G>A (p.G155fsX203), c.622G>T (p.G208W) and c.206A>C (p.Q69P).
自身免疫性多内分泌综合征1型(APS-1, OMIM 2403000)是一种由自身免疫调节因子(AIRE)基因引起的罕见常染色体隐性遗传病。APS-1的主要症状是慢性皮肤粘膜念珠菌病、自身免疫性肾上腺皮质功能不全(Addison病)和甲状旁腺功能减退。迄今为止,已经在APS-1患者中发现了100多种不同的AIRE基因突变。这些不同的突变以不同的方式影响AIRE蛋白的结构和功能,最终导致APS-1的发生。到目前为止,在中国仅报道5例APS-1,主要突变位点为c. 769C>T (p.R257*)、c. 55g >A (p.A19T)、c. 463g >A (p.G155fsX203)、c. 622g >T (p.G208W)和c. 206a > c (p.p q69p)。
