Phosphoregulation of photorespiratory enzymes in Arabidopsis thaliana

Photorespiration is an essential process in oxygenic photosynthetic organisms, and it is triggered by the oxygenase activity of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (RuBisCO) to produce one molecular 3-phosphoglycerate and one molecular 2-phosphoglycolate. The toxic 2-PG is recycled by the photorespiratory pathway which includes eight core enzymes and takes place in chloroplasts, peroxisomes and metochondria and cytosol. Although the photorespiration leads to a reduced efficiency of the photosynthetic CO₂ assimilation and thereby is considered as a wasteful process, the growth phenotype of the photorespiratory enzymes can reflect the importance of this process in normal growth and development of air-grown plants. Normally, for most photorespiratory enzyme mutants, they exhibit small, chlorotic plants sometimes non-viable in air which are not observed when the mutants are grown under high CO₂ condition that limit the photorespiration by reducing the RuBisCO oxygenase activity. Photorespiratory cycle interacts with several major primary metabolic pathways, thus is a highly regulated and extensive works. Current data show that seven of eight core photorespiratory enzymes could be phosphorylated and the protein phosphorylation seems to be a critical regulatory component of the photorespiratory cycle. In order to better understand the regulation of the photorespiratory cycle, we explored the effect of SHMT1 and HPR1 phosphorylation/non-phosphorylation events on plant physiology and metabolism by several methods: Site-directed mutagenesis assay, complementation assay, activity assay, stomatal aperture assays, plant salt/drought resistance assays, metabolites measurement, gas exchange measurement. The results show the phosphorylation mimicking version of HPR1 at T335 results to a less HPR1 activity and retarded growth at the ambient air condition. For the phosphorylation mimicking version of SHMT1 at S31 resulted in a less stability leading to a reduced resistance to drought and salt stress. The decline of resistance against abiotic stress was mainly due to impairment in the closure of stomata which were unable to respond properly to ABA probably because of a default in the PLC pathway. So there results indicate that the phosphorylation of SHTM1 leads to a negative effect for the plant growth especially under stress condition. Thus, we propose that the SHMT1 can be phosphorylated at a basic level under normal growth conditions, once the photorespiratory flux is increased such under salt stress condition, the SHMT1 should be dephosphorylated to stabilize SHMT1 and sustain a high photorespiration flux to cope with reduced CO₂ availability.
Quality assessment of eggs from laying hens fed with a plant mixture supplement

The aim of this study, carried out on 60 TETRA SL (32 weeks old) laying hens, was to determine the effect of dietary plant mixture (sea buckthorn meal (50%), walnut leaves (25%) and bilberry leaves (25%)) on egg quality. The birds were allocated in two experimental groups, 30 birds each. The control group (C) was fed a conventional diet, without the experimental additive. All diets had similar levels of protein (18.90% (C) and 18.55% (E)) and energy (3962 Kcal/Kg (C) and 4009 Kcal/Kg gross energy (E)). Diet of hens from experimental group was supplemented with 1.0% of plant mixture. In the experimental period, 18 eggs from each group were collected twice (week 2 and 4 of experiment). Eggs were analyzed for proximate composition contents. The experimental group additions of plant mixture increased the crude protein in egg yolk and decreased the crude fat. Our results show that addi­tion of 1.0% plant mixture improved the quality of eggs and it can be recommended in feed for laying hens.
SCHEMA BASED STO RAGE OFXML DOCUMENTS IN RELATIONAL DATABASES

XML (Extensible Markup language) is emerging as a tool for representing an d exchanging data over the internet. When we want to store and query XML data, we can use two approaches either by using native databases or XML enabled databases. In this paper we deal with XML enabled databases. We use relational databases to store XML d ocuments. In this paper we focus on mapping of XML DTD into relations. Mapping needs three steps: 1) Simplify Complex DTD’s 2) Make DTD graph by using simplified DTD’s 3) Generate Relational schema. We present an inlining algorithm for generating relational schemas from available DTD’s. This algorithm also handles recursion in an XML document.
Getting under your skin

Some people have RFID chips implanted in their hands so they can open their doors by waving at them. A US-based company, VeriChip Corporation, is the main driving force behind this application. Called the VeriChip, each device comes in the shape of a glass capsule containing a microchip and a copper coil that works as antenna. The chip is injected with a needle just under the skin in the triceps area of the right arm. The medical reasons why anybody would want to be implanted with one of these chips are purely preventive. Other applications of RFID chips are discussed in this paper.

A NOVEL APPROACH TO INFER USER SEARCH GOALS FOR OPTIMIZE RESULT

Search engine is one of the most significant applications for internet users. Different users may have different search targets when they submit broad-topic to a search engine. Most times, search engine does not deliver what user needs. So to produce best relevant results, there is necessity to analyse user goals behind searching. Inference and analysis of it can be very useful in improving quality of a search engine's results. In this paper, a framework is projected to examine user search areas for a query by clustering the feedback sessions. Feedback sessions are made from user click-through logs and can more accurately predict the information requirements of users. Post feedback session formations, pseudo-documents are generated which better illustrate feedback sessions for clustering. For clustering, bisecting K-means algorithm is used. After cluster formations, restructuring of web search results is done by calculating smallest distance. At the end, to evaluate the performance of inferring user search goals, a new criterion “Classified Average Precision (CAP)” is proposed.
When pets become pests: the role of the exotic pet trade in producing invasive vertebrate animals

Author(s): Lockwood, JL; Welbourne, DJ; Romagosa, CM; Cassey, P; Mandrak, NE; Strecker, A; Leung, B; Stringham, OC; Udell, B; Episcopio-Sturgeon, DJ; Tlusty, MF; Sinclair, J; Springborn, MR; Pienaar, EF; Rhyne, AL; Keller, R | Abstract: © 2019 The Authors. Frontiers in Ecology and the Environment published by Wiley Periodicals Inc. on behalf of the Ecological Society of America. The annual trade in exotic vertebrates as pets is a multi-billion-dollar global business. Thousands of species, and tens of millions of individual animals, are shipped both internationally and within countries to satisfy this demand. Most research on the exotic pet trade has focused on its contribution to native biodiversity loss and disease spread. Here, we synthesize information across taxa and research disciplines to document the exotic pet trade's contribution to vertebrate biological invasions. We show recent and substantial worldwide growth in the number of non-native animal populations introduced via this invasion pathway, which demonstrates a strong potential to increase the number of invasive animals in the future. Key to addressing the invasion threat of exotic pets is learning more about the socioeconomic forces that drive the massive growth in the exotic pet market and the socioecological factors that underlie pet release by owners. These factors likely vary according to cultural pet-keeping traditions across regions and whether purchases were legal or illegal. These gaps in our understanding of the exotic pet trade must be addressed in order to implement effective policy solutions.
Temporal spectral signatures of fire scars in Savanna Woodland

Bidirectional reflectance factors (BRFs) of two fire scars in savanna woodland type vegetation (eastern Senegal) have been examined. Measurements were carried out in red and near-IR bands during postfire time spans of 11 and 36 days, and the results were compared to BRFs from unburned areas. The Normalized Difference Vegetation Index (NDVI) was determined as well. In both proper channels the postfire BRFs displayed a rapid spectral recovery. After a shorter spectral increase, the NDVI appeared to stabilize at a level significantly under the level of surrounding dry grasses.
Design and Fabrication of a Stair Climbing Hand Truck

This topic deals with the designing and manufacturing of a hand truck, which can climb stair with less effort compare to carry it manually. The technical issues in designing of this vehicle are the stability and speed of the vehicle while climbing stairs. However, the steepness of the stairs is also the important concern of this study. The uses of this special vehicle are in the frequent lift of goods such as books for library, medicines for hospital, regular goods of any technical or non technical institutes, or transportation any toxic material for industries and give freedom to the retarded person or paralyzed patients to move anywhere over flat surface as well as stairs. The vehicle has four wheels arrangement to support its weight when it moves over the flat surface. Each set wheel frame consists of three wheels attached with nut and bolt. Using of this vehicle, the labor cost can be reduced as well as huge amount of loads can be transferred uniformly with less power consumption. Moreover, considering some drawbacks due to lack of implementation of all techniques during manufacturing phase the test and trial run showed considerably significant and encouraging results that might help the future researchers to incorporate a gear box and steering mechanism to make the vehicle more versatile.
The influence of dietary corn distillers dried grains with solubles during gestation of sows on fatty acid composition of colostrum and offspring

Abstract: Thirty-six sows were randomly assigned to three treatments and fed 0, 125, or 250 g kg-1 corn distillers dried grains with solubles (DDGS), which aimed to evaluate the effects of feeding DDGS to sows during gestation on the fatty acid composition of colostrum and offspring. In colostrum, feeding 0–250 g kg-1 DDGS resulted in linear increase (P < 0.001) in linoleic acid (18:2n-6) level (from 14.7% to 19.8%) and total polyunsaturated fatty acid (PUFA) level (from 16.9% to 22.8%), and linear decrease (P < 0.05) in levels of palmitic acid (16:0), oleic acid (18:1 cis-9), and total saturated fatty acid (SFA). In addition, the percentage of arachidonic acid (20:4n-6) in colostrum was increased from 0.56% to 1.23% (linear effect, P < 0.001, and quadratic effect, P = 0.010) with increasing level of DDGS. Feeding DDGS to sows resulted in linear increase (P < 0.05) in levels of 18:2n-6 (from 13.9% to 20.4%), 20:4n-6 (from 0.53% to 0.73%), docosahexaenoic acid (22:6n-3, from 0.28% to 0.37%), and total PUFA (from 15.9% to 22.6%), and linear decrease (P < 0.001) in levels of 16:0 and SFA of carcass of newborn piglets. The results demonstrated that feeding 125 or 250 g kg-1 corn DDGS to sows increased the proportions of 18:2n-6, 20:4n-6, and total PUFA and decreased the proportions of 16:0 and total SFA in sow colostrum and the carcasses of newborn piglets, implying that inclusion of corn DDGS in diets for sows can alter fatty composition of colostrum and piglets.
Evaluation pharmacocinétique/pharmacodynamique in vitro et in vivo de l'association aztréonam-avibactam

L'augmentation des resistances aux antibiotiques ces dernieres annees et le faible nombre de nouveaux antibiotiques recemment approuves ont suscite un interet considerable pour les associations medicamenteuses. Parmi celles-ci, les associations β-lactamine-inhibiteur de β-lactamases, comme l’aztreonam-avibactam (ATM-AVI), visent a surmonter la resistance due a la production de β-lactamases, l'un des principaux mecanismes de resistance chez les bacteries a Gram negatif. Cependant, les interactions PD entre molecules associees peuvent etre complexes. Afin de mieux comprendre la PK/PD de l’ATM-AVI, deux problematiques ont ete abordees dans cette these :i. La PK de l’ATM-AVI au site infectieux. Une etude de microdialyse realisee chez le rat avec ou sans peritonite a montre que la distribution de l’ATM-AVI dans le liquide peritoneal etait rapide et que les concentrations au site infectieux pourraient etre predites a partir des concentrations sanguines.ii. L’interaction PD entre ATM et AVI. Des etudes de checkerboard analysees avec un modele Emax ont permis de caracteriser l’effet de l’AVI sur la CMI de l’ATM en termes d’efficacite et de puissance en presence de souches multi-resistantes. Pour completer ces resultats, un modele PK/PD a ete developpe a partir de donnees in vitro afin d’evaluer l’evolution de l’effet combine de l’ATM-AVI au cours du temps et d’etudier la contribution individuelle de chacun des effets de l’AVI a l’activite combinee. Selon les resultats de cette modelisation, l’activite bactericide de l’association serait principalement expliquee par l’effet potentialisateur de l’AVI et ce malgre sa capacite a prevenir la degradation de l’ATM de maniere efficace.

A collection of references at the end of the article provides pointers to some of the current work in this field.
ANALYSIS OF ROUCAIROL AND CARVALHO APPROACH IN DISTRIBUTED MUTUAL EXCLUSION

Critical section problem is a well known problem in Computer Science. It arises when multiple processes or threads simultaneously try to access shared resources like physical devices or logical objects. In Conventional Operating System Design, we use semaphores to solve this one. In Distributed System due to absence of shared memory we cannot implement the same solution. Various approaches are given to solve the critical section problem in Distributed System. An algorithm that solves critical section problem should have following properties like fairness along with deadlock freedom, freedom from starvation and fault tolerant. Ricart and Agrawala suggested message based approach to get mutual exclusion in Distributed System. This approach fairly deals with the critical section problem. Roucairol and Carvalho suggested an optimization for the given approach. This paper is shedding lights on the proposed optimization. This paper finally concludes that though the optimization has a better performance over the original one yet this one is compromising with the fairness.

Adaptive noise cancelling of motion artifact in stress ECG signals using accelerometer

Electrocardiographic (ECG) signals obtained from stress examinations are diagnostically significant in detecting a number of heart diseases, which may not be apparent when the patient is at rest. However, the noise produced by the environment and by the patient often distorts the ECG data. Motion artifact, the most prevalent and difficult type of noise to filter in exercise ECG, corrupts the intelligibility of the desired signal thus reducing the reliability of the stress test. In this paper, the researchers aim to demonstrate a new adaptive filtering method for stress ECG signals. This noise cancellation scheme uses an accelerometer as a source of noise reference. Experiments involving single-axis and dual-axis motion sensors are conducted to evaluate the efficiency of this technique. The acquired real ECG and accelerometer data are simultaneously processed and analyzed using the two most widely used adaptive filtering algorithms, least mean squares (LMS) and recursive least squares (RLS). The results show that the proposed method can be adapted to effectively reduce motion artifact in stress ECG by just using a single-axis noise reference.
New Perspectives on Urban Sustainability Analysis: Space-Time Evaluation in the context of Multicriteria Decision-making

In the last decades researchers have emphasized the link between evaluation and planning, as an indispensable component in seeking reasonable and balanced choices for regional planning and economic policy. According to these scholars, evaluation becomes part of planning throughout the whole process of policy preparation. Multicriteria analysis (MCA) is one of the most utilized techniques for performing evaluation studies dealing with the ranking of alternatives in the presence of conflicting objectives. It plays also a key role in urben sustainability analysis. After a critical judgement of the potential of MCA methods, this paper seeks to explain in which way MCA can be modified in order to become a flexible tool for urban decision-making and to propose how this task may be accomplished by means of an integration between spatial analysis and MCA with a view to sustainable cities.
A Disruptive Treatment to Prevent Amputation and Enhance Limb Salvage in an Elderly Patient

Background: Chronic wounds are a growing problem internationally, termed a silent epidemic. To combat this epidemic, it is not sufficient to rely on traditional wound care treatments alone, but to look to innovative and alternative therapies. The indispensable role of oxygen in wound healing is well-discussed in the literature, and in the past two decades the topical application of oxygen has shown promising results in the healing of chronic wounds. However, the toxic effects of oxygen are usually not appreciated and can often lead to wound necrosis and gangrene in wounds with compromised blood supply. While wounds with adequate blood supply contain free radical quenchers (catalase, superoxide dismutase and reduced glutathione) which neutralize the free radicals (reactive oxygen species) released as a by-product of the Krebs cycle, wounds with deficient blood supply are deficient in free radical quenchers and are further damaged by exposure to oxygen as a result of reperfusion injury/oxygen toxicity. Topical hyperbaric oxygen (THOT®) uses low oxygen tensions in the hyperbaric range to stimulate angiogenesis, while preventing excessive oxygen toxicity. The result is the induction of marked angiogenesis, with increasing capacity for quenching reactive oxygen species, resulting in wound healing of ischemic wounds. Case Presentation: This case report describes a 95-year-old Caucasian female who presented with a stage IV chronic necrotic ulcer on her lower left leg. Surgical pathology results revealed calcifying vasculopathy, which is thought to be responsible for deficient blood supply to the leg, leading to a necrotic, chronic leg ulcer of her left leg. After traditional wound therapies were unsuccessful, she was considered for leg amputation. The introduction of adjunctive treatment with topical hyperbaric oxygen therapy saw complete healing of the wound within 15 weeks. The wound remained closed, without the presence of scar tissue, with no signs of wound breakdown at three-month and six-month follow-ups. Conclusions: Chronic hypoxic wounds with vascular insufficiency are considered “unlikely to heal” and tend to lead to limb amputation. The use of THOT® technology, with low hyperbaric oxygen tensions to neutralize free radicals released by the Krebs cycle when oxygen contacts the wound, prevents oxygen toxicity and results in angiogenesis necessary for wound healing. In this way, THOT® treatment was able to convert the hypoxic “unlikely to heal” wound considered for limb amputation into one which healed, with limb salvage. The results of this case report demonstrate the potential for complete healing of chronic hypoxic wounds even in complex cases with multiple confounding factors preventing wound healing, using a cost-effective treatment that is easily accessible to patients.
A MAC protocol for a wireless LAN based on OFDM-CDMA

Local access encompasses requirements of high throughput, transfer performance, flexibility, and ease of user/terminal mobility at a relatively low cost. While some of these targets can often be met satisfactorily with wired infrastructures, it is getting increasingly popular to resort to wireless access (wireless LAN), mainly because of its simpler deployment, continuous coverage, availability of ad hoc connectivity, and user/terminal mobility support. This article outlines the proposal of a broadband quality-oriented WLAN system. The basic system characteristics are described, with details given on a MAC protocol supporting IP and exploiting an OFDM-CDMA technique.

Urgent Care of Fetal Heart Rate Bradycardia

As fetal heart rate decreases if fetal vagal nerve center is excited by the stimulation of low PaO2 lower than 50mmHg in fetal hypoxia, sudden transient or continuous fetal bradycardia, fetal hypoxic damage, particularly fetal brain damage followed by hypoxic ischemic encephalopathy (HIE) and infantile cerebral palsy in severe hypoxia, in the loss of fetal heart rate (FHR) variability, urgent care is needed in the labor. Fetal acoustic bradycardia listened after uterine contraction with stethoscope was warned to be dangerous to the beginner in old time, and also in modern fetal monitoring detected with various FHR monitor. Microbial infection with TORCH and syphilis also develop FHR change, e.g. cytomegalovirus.
