Activity of Iron oxide nanoparticles on bacterial biofilm formation

Biofilm is important virulence factor play an essential role in bacterial pathogenicity through trigger antimicrobial agents. Nanoparticles have antimicrobial properties and the antimicrobial activity depend on nanoparticles size and concentration. This study demonstrated the antimicrobial activity of iron oxide nanoparticle against Gram-positive and Gram-negative bacteria within 20 hours. Particles of iron oxide was synthesized via co-precipitation method. The particles obtained had an average diameter 85.9 nm; the particles were used to inhibit Staphylococcus aureusand Escherichia coli biofilm on polystyrene surface. The bacteria were added in 96-well plates to incubate with iron oxide nanoparticles and without iron oxide nanoparticles as control. The biofilm was measured using the safraninstaining method that showed variable results depending on bacterial species. However, It was seen that exposure of cells to iron oxide particles showed increased biofilm formation on polystyrene plates.The highest augmentation was recorded for S. aureusin a concentration of 0.5mg/ml and approaching (78.8%) highly significant p≤0.05 and the augmentation was not achieved in a concentration of 50 mg/ml p˃0.05, The augmentation of S. aureusin a concentration of 5mg/ml gave (75.8%). Augmentation percentage of E.coli at 50 mg/ml was 36.9% not significant p˃0.05 compared with the control, while at concentration 5mg/ml showed (59.8%) augmentation p>0.05. Percentage augmentation of E.coli in concentration of 0.5mg/ml gave (43.4%) nonsignificantp˃0.05. Sera proteins of patients infected withS. aureusand E. coli were exhibited reactivity toS. aureusand E. coli antigens (whole cells ) as: three strains of S. aureusantigens agglutinated in titer 1:128 of patients sera ( antibodies ) while the remaining werethree S. aureusantigens agglutinated with the patients sera in titer 1:16, 1:64 and 1:256 respectively. E. coliantigens (whole cells ) reactivitywith patients serashowed: two of antigens agglutinated in titer 1:32 of patients sera ( antibodies ) while three of E. coli antigens agglutinated in titer 1:16 , 1:64 , 1:128 and 1:256 respectively. Sera proteins of patients infected by S. aureus& E. coli exhibited reactivity with S. aureus&E. coli antigens (whole cells ) as The highest agglutinated in titer 1:256, 1:128 respectively of patients sera ( antibodies ). Whereas results lowest agglutinated in titer 1:16, 1:8was appeared on the isolates S. aureus& E. coli. Our result indicated that iron oxide nanoparticles have not antibiofilm activity against bacteria cells within 20 hours for E.coli and S aureus except at concentration 50mg/ml for S.aureus gave (18.2%) inhibition rate. The IONPs efficacy depends on the incubation time, bacterial strain and nanoparticles concentration. In addition antiS aureusantibodies titer more than antiE.coliantibodies, So the biofilm of gram positive bacteriacan be control by IONPs more than gram negative bacteria biofilm in patients.
A GLOBAL GENETIC NETWORK CHARTS THE FUNCTIONAL MAP OF A CELL

Genome sequencing projects are providing an unprecedented view of genetic variation. However, our ability to interpret genetic information to understand cell function and predict phenotypes, including disease, remains limited, in large part to the extensive buffering of genomes that makes most individual genes dispensable for life. Recent studies applied automated genetics to construct a global genetic interaction network for a model cell to explore the extent to which genetic interactions reveal cellular function and contribute to complex inherited traits, as well as to discover the general principles of genetic networks.
A note on the Erdős-Hajnal hypergraph Ramsey problem

We show that there is an absolute constant c > 0 such that the following holds. For every n > 1, there is a 5-uniform hypergraph on at least 2 cn1/4 vertices with independence number at most n, where every set of 6 vertices induces at most 3 edges. The double exponential growth rate for the number of vertices is sharp. By applying a stepping-up lemma established by the first two authors, analogous sharp results are proved for k-uniform hypergraphs. This answers the penultimate open case of a conjecture in Ramsey theory posed by Erdős and Hajnal in 1972.
Wet cupping therapy improves mu opioid receptor expression and pain threshold in animal models of inflammation

Background & Objectives: Treatment of chronic pain using NSAIDs, steroids, opioids, and herbs has been associated with many complications with the long-term use. Wet cupping therapy (WCT) has been used to reduce pain, by triggering mu opioid receptor expression. We conducted this study to compare the effectiveness between WCT with oral opioids for pain management. Methodology: It was an experimental study with randomized control group post-test only design. Thirty two male white rats of strain Wistar were divided into four groups: (1) Group-NC; mice in this group were given nothing as a negative control group, (2) Group-CFA; group that was given Complete Freund’s Adjuvant (CFA) only as a positive control group, (3) Group-WCT; mice were given CFA and WCT, and (4) Group-O was given CFA and oral opioids. The measured variables were pain threshold value and mu opioid receptors. Statistical analysis was done us(ing SPSS software (version 22.0, Chicago, IL). Results: The results showed no significant differences in the expression of mu opioid receptors between Group-NC and Group-CFA (p = 0.061). There were significant differences in the expression of opioid receptors between Group-CFA and Group-WCT (p < 0.001), and also between WCT group and Group-O (p = 0.002). The differences of pain threshold value were only significant between Group-NC (p = 0,006) and GroupCFA (p = 0,013) with Group-O. Conclusion: Wet cupping therapy triggers the expression of mu opioid receptors. Wet cupping therapy as effective in relieving pain as opioids.
Practical evaluation of NoSQL/NewSQL systems in the environment emulating interactive social networking actions

Cassandra is an open source distributed database system that is designed for storing and managing large amount of data across commodity servers [2]. Cassandra is considered to be NoSQL data store and according to data model classification it belongs to column family category. As most of the modern NoSQL databases, Cassandra doesn’t provide ACID guarantees and is not based on the traditional relational model. The NuoDB database is SQL compliant and has been called ‘NewSQL’ [3]. NewSQL databases are considered to be fast enough to handle big data challenges, they are horizontally scalable as NoSQL databases, although they initially designed to provide ACID [4]. BG is a benchmarking
Integer Ambiguity Resolution by Mixture Kalman Filter for Improved GNSS Precision

Accurate carrier-phase integer ambiguity resolution is fundamental to high-precision global navigation satellite systems (GNSSs). Real-time GNSSs typically resolve the ambiguities by a combination of recursive estimators and integer least-squares solvers, which need to be reset when satellites are added or cycle slip occurs. In this article, we propose a mixture Kalman filter solution to integer ambiguity resolution. By marginalizing out the set of ambiguities and exploiting a likelihood proposal for generating the ambiguities, we can bound the possible values to a tight and dense set of integers. Thus, we extract the state and integer estimates from a mixture Kalman filter. The proposed approach yields an integrated method to detect cycle slip and initialize new satellites. Numerical analysis and experimental results indicate that the proposed method achieves reliable position estimates, repeatedly finds the correct integers in cases when other methods may fail, and is more robust to cycle slip.
Towards Natural and Accurate Future Pose Prediction for Human and Animals

This work addresses the problem of future 3D pose prediction for articulate objects given their observed skeleton sequence. Current methods represent the skeletons of articulate objects as a set of 3D joints, which ignore the relationship between joints and fails to encode ﬁne-grained anatomical constraints. Moreover, conventional Recurrent Neural Networks (RNNs) are employed to model motion context, which inherently have difﬁculty in capturing long-term dependencies. To address these problems, we propose a Lie algebra representation that models the skeleton as a whole and encodes anatomical constraints explicitly. In addition, a novel RNN structure is designed for motion context modeling, capturing both local contexts for individual frames and global contexts for entire sequences. We explore the possibility to apply our method to a range of objects including human, ﬁsh, and mouse. Extensive experiments show that our approach achieves superior pose predictions over the state-of-the-art methods.
The Relationship between Prevention and Treatment of Colorectal Cancer and Cancerous Toxin Pathogenesis Theory Basing on Gut Microbiota

Gut microbiota is a diverse consortium of bacteria, fungi, protozoa, and viruses in the gut of all mammals. Gut microbiota remains in steady state under normal conditions. Changes in the internal and external environment may cause gut Microbiota to be out of tune. Malignant tumors are one of the major diseases currently endangering human health. CRC (colorectal cancer) has a significant upward trend in morbidity and mortality in many parts of the world. Technological advances have not yet brought about a breakthrough in the efficacy of CRC. The development of colon cancer is closely related to gut microbiota imbalance. According to more than 60 years of clinical practice, Professor Zhongying Zhou first proposed the pathogenesis theory of “cancerous toxin” in the 1990s and believed that cancerous toxin was a key pathogenesis of tumor development. Under the guidance of the theory of cancerous toxin, combined with clinical practice, Professor Zhou created an effective anticancer Chinese herbal compound, Jiedu Xiaoai Prescription. This paper summarizes recent hotspots related to gut microbiota and the occurrence, development, and prevention of colon cancer at home and abroad. The relationship between gut microbiota and cancerous toxin theory is proposed, and the feasibility of further studying the biological basis of cancerous toxin pathogenesis theory from the perspective of gut microbiota is pointed out.
C OSM O PEN : Dynamic reverse-engineering on a budget Technical Report COMP-002-2008

: In this article we present C OSM O PEN , a reverse engineering tool optimised for the behavioural analysis of complex layered software. C OSM O PEN combines cheap and non-intrusive observation techniques with a versatile graph manipulation engine. By programming different graph manipulation scripts, the “focal length” of our tool can be adapted to the different abstraction levels found in complex software. We illustrate how our tool can be used to extract high-level behavioural models from a complex multithreaded platform (GNU/Linux, CORBA middleware).
Evaluation of GPS Standalone Single Frequency Receiver Autonomous Integrity Monitoring Algorithms

The aviation navigation aided by the position estimation supplied by a GPS (Global Positioning System) receiver needs to meet the standardized requirements defined by the International Civil Aviation Organization. A Receiver Autonomous Integrity Monitoring (RAIM) algorithm needs to be implemented to ensure these requirements. The algorithm detects and excludes faulty satellites and computes the necessary protection levels for the GPS position solution. The conventional RAIM algorithm (weight least squares residuals), a total least squares based algorithm and a proposed one are compared in terms of detection capability and performance. The proposed algorithm considers both pseudorange and carrier phase measurements in the total least squares algorithm in order to guarantee improved results. These measurements were acquired with use of a standalone, single frequency receiver which creates the problem related to the use of the carrier phase measurements. An algorithm was implemented to solve the problem of the unknown integer number of carrier cycles. This algorithm showed a more accurate position solution which enhanced the proposed RAIM results. In conclusion, the thesis recommends a new RAIM algorithm which improved the performance metrics required for aviation guided by GPS. The results were supported by real data acquired on the laboratory of the Instituto de Telecomunicações for L1 frequency.
Factors affecting discharge time of well differentiated thyroid cancer patients receiving 131I therapy: Five years’ experience

Introduction:The post-surgical management of patients with differentiated thyroid cancer include ablation of remnant local and distant metastatic tissues with 131I therapy, which accentuates isolation of the patient in order to avoid unnecessary radiation exposure to the care givers, general public and the environment. The duration of isolation is subject to the reduction of exposure to the safe limit as defined by the regulatory bodies. Methods:This study presents the correlation of isolation period of the radioiodine treated patients with administered activity, surgical endeavors and the disease extent. The study was conducted on 222 patients at the Institute of Radiotherapy and Nuclear Medicine (IRNUM), Peshawar, Pakistan from 2008-2012. Results: The number of patients in the four groups on the basis of 131I administered activity were, 131I administration while 27.03%, 24.32%, 10.81%, 6.31%, and 0.90% patients were kept in isolation for 72, 96, 120, 144 and 168 hours, respectively. Conclusion: The isolation period of radioactive 131I treated patients is directly related to the 131I activity administered, size of the remnant, and extent of the disease.
Study on Floral Traits of Male Sterile and Fertile Lines for Hybrid Development in Bread Wheat

Wheat constitutes the world’s most important food crop and its different properties have made this crop the most important staple food of 35 percent population of the world. India in the recent past has emerged as second largest producer of the wheat after China. Wheat production has increased more than 17 times from 6.46 million tonnes in 1952 to 110.15 million tonnes in 2016-17 (Anonymous, 2018). The average yield has increased more than 4 times from 0.66 tonnes ha -1 in 1950 to 3.216 tonnes ha -1 in 2016-17.At present in India, wheat is the second most important cereal crop after rice grown under diverse agro-climatic condition. Despite this success, India cannot be complacent with regard to the efforts to produce more to meet the food security requirement.

In the Light of Reading Strategies Comprehension improvement (Text Book, Online Material and Smartphone Application)

The reading comprehension study is considered as one of the most important areas in language education. Since 1975 several matters took the attention to be discussed either the nature of reading comprehension as a process or might be the effective of reading comprehension instruction. Tracing the latest update by researchers shows that the new technologies are employed to make the process of reading easier. Special concerns should be giving to the soul of learning which is reading skill and the strategies of reading. Due to the variety of reading strategies in different environments, how do the learners react with the paper based texts are discussed and no gabs left in different societies; consequently the online reading process begins when the use of internet becomes a part of the students life in early of this century. Gradually, when the internet is accessible in the smartphones, knowledge and information are spreader in a massive way which leads us to find out and explore the differences between the traditional way of writing as mentioned or do the learners have others attitude when they engaged to the smartphones in terms of reading skills

A Dirty Paper Coding MODEM

—Dirty Paper Coding (DPC) is a set of techniques for reducing the effects of interference on a signal across the channel by using precoding techniques at the transmitter to shape and transform the original message. It allows the cancelation of arbitrary known interference at the transmitter while keeping the power required to transmit the signal constrained. The main objective of the dissertation was to implement a complete end-to-end transmission system which employs DPC. Obviously, both ends of the system need to be coordinated and compatible. This involves implementing the encoding techniques performed at the transmitter and the respective decoding techniques at the receiver. The implemented system was used to perform several simulations where the noise parameter in the channel will vary. From these simulations, the Bit Error Rate (BER) and the total number of errors on the decoded message will be measured for different Signal to Noise Ratio (SNR) conditions. The simulations were performed using Matlab software.
Precise and Comprehensive Provenance Tracking for Android Devices

—Detailed information about the paths that data take through a system is invaluable for understanding sources and behaviors of complex exﬁltration malware. We present a new system, ClearScope, that tracks, at the level of individual bytes, the complete paths that data follow through Android systems. These paths include the original source where data entered the device (such as sensors or network connections), ﬁles in which the data was temporarily stored, applications that the data traversed during its time in the device, and sinks through which the data left the device. The ClearScope system design enables this unprecedented level of provenance tracking detail by 1) structuring the provenance representation as references, via provenance tags , to provenance events that record the movement of data between system components and into or out of the device and 2) adopting a split design in which provenance events are streamed to a remote server for storage, with only the minimal information required to generate the tagged stream of events retained on the device. ClearScope also includes compiler optimizations that enable efﬁcient provenance tracking within applications by eliminating unnecessary provenance tracking computations and adopting and efﬁcient aggregate provenance representation for arrays when all array elements have the same provenance. Experience using ClearScope to analyze the notorious Adups FOTA malware highlights the signiﬁcant beneﬁts that this level of comprehensive detail can bring. Performance experiments with the Caffeine Mark benchmarks show that the overall ClearScope provenance tracking overhead on this benchmark suite is 14%.
The Fluorescence Properties of Graphene Oxide

Graphene oxide (GO) is an intermediate on the route to chemically derived graphene, and it is easily synthesized. Its chemical structure is heterogeneous and consists of both, large areas of conjugated sp 2 -systems and various electronically isolated oxygen containing functionalities [1]. Contradictory optical properties have been found. A band gap which enables photoluminescence is introduced into GO with increasing oxidation level [2, 3]. Due to the remaining large -electron system, it can also act as a quencher of fluorescence [4]. GO is well dispersible in water and therefore of interest in many (bio)analytical applications. By tuning its size, oxidation level, number of layers and additional chemical functionalization it is possible to create tailored materials with specific optical properties.
A Case Study of Early Supplier Involvement in a Radical Innovation by a New Venture-The Eclipse 500 Very Light Jet

The Eclipse 500 Very Light Jet (VLJ), developed by Eclipse Aviation, is a new type of personal jet that is expected to revolutionise the market. Its sale price and operating costs are historically low and a very low time to market and high number of advance orders were achieved; furthermore, it is an example of a radical innovation developed by a new venture. This paper is organised as a case study of supplier involvement in the development of the Eclipse 500. It assesses hypotheses concerning supplier involvement and time to market, development cost savings, suppliers’ specific investments and qualification of supplier abilities. A research question about other effects of supplier involvement is also answered. Selected employees from Eclipse Aviation responded to two questionnaires; a number of relevant press releases from this manufacturer were also analysed through a framework of supplier involvement. It was concluded that a negative relationship exists between supplier involvement and time to market and that a positive one is present between supplier involvement and development cost savings. The qualification of supplier abilities and supplier specific investments have had a positive relationship with the extent of supplier involvement in this case. Eclipse Aviation was more involved with the suppliers chosen for the quality of their products and supplier involvement was important in reaching final product quality goals. Further research is possible by performing a multiple case study of Eclipse Aviation and its main competitors and see if the conclusions reached in this work still hold.
On the Hausdorff Dimension of the Visible Koch Curve

In geometry, a point in a set is visible from another point if the line segment connecting two points does not contain other points in the set. We show that the Hausdorff dimension is 1 for the portion of the Koch curve that is visible from points at infinity and points in certain defined regions of the plane.
