Microservices-based software architecture and approaches

In the last few years, a revised software architecture style has been developed to design new software applications. This architecture style is particularly suited for use cases in the aerospace industry, from an independently deployable software service. The microservices architectural style develops a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms. These services are built around business and mission capabilities and independently deployable by fully automated machinery. With microservices, some types of applications become easier to build and maintain when they are broken down into smaller, composable pieces that work together. Each component is then developed separately, and the application is then simply the sum of its constituent components. This is in contrast to a traditional, “monolithic” application which is all developed in one piece. This paper will discuss, several aspects of microservices-based architecture, including several potential use cases for the aerospace industry. The characteristics of microservice-based architecture such as componentization, organization, endpoints and messaging mechanisms. The technical implementation of microservices by reviewing containerization, services communication and related architectural components. Specific open source projects and components that can be utilized to build microservices-based architecture. A sample set of use cases.
MHC Class II Isotype- and Allele-Specific Attenuation of Experimental Autoimmune Encephalomyelitis1

Most autoimmune diseases are associated with certain MHC class II haplotypes. Autoantigen-based specific immune therapy can lead either to beneficial or, in the context of inflammatory conditions, detrimental outcomes. Therefore, we designed a platform of peptides by combinatorial chemistry selected in a nonbiased Ag-independent approach for strong binding to the rat MHC class II isotype RT1.Dn allelic product of the RT1n haplotype that is presenting autoantigen in myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis in LEW.1N rats. Peptide p17 (Ac-FWFLDNAPL-NH2) was capable of suppressing the induction of and also ameliorated established experimental autoimmune encephalomyelitis. MHC class II isotype and allele specificity of the therapeutic principle were demonstrated in myelin basic protein-induced experimental autoimmune encephalomyelitis in LEW rats bearing the RT1l haplotype. A general immunosuppressive effect of the treatment was excluded by allogeneic heart transplantation studies. In vitro studies demonstrated the blocking effect of p17 on autoantigenic T cell responses. We thus demonstrate a rational design of strong MHC class II-binding peptides with absolute isotype and allele specificity able to compete for autoantigenic sequences presented on disease-associated MHC class II molecules.
Effects of perineural capsaicin treatment on cardiopulmonary reflexes elicited by laryngeal instillations of capsaicin and distilled water in sevoflurane-anesthetized dogs.

The aim of this study was to determine the effect of perineural capsaicin (CAPS) treatment on cardiopulmonary reflexes elicited by topical laryngeal instillation of CAPS and distilled water (DW) in sevoflurane-anesthetized dogs. Cardiopulmonary reflexes elicited by CAPS (10 microg/ml, 10 ml) were attenuated by perineural CAPS treatment to the superior laryngeal nerves (SLNs) (P<0.05), whereas those by DW (10 ml) remained unaffected (P>0.05). The reflex responses to DW that remained even after the perineural CAPS treatment were eliminated by laryngeal anesthesia with lidocaine. These results suggest that cardiopulmonary reflexes from the laryngeal mucosa elicited by CAPS instillation can be blocked by perineural CAPS treatment to the SLNs, which may result from inhibition of the laryngeal CAPS-sensitive C-fiber afferents.
Impact of Perceived Fairness on Performance Appraisal System for Academic Staff-General Sir Jhon Kotelawala Defence University

This study investigates the employees’ perception of fairness in the performance appraisal system for academic staff of the General Sir Jhon Kotelawala Defence University. The perception of fairness in performance appraisal system consists of three main factors: Distributive justice, procedural justice, performance feedback and are used as independent variables and effectiveness of the performance appraisal system as dependent variable. The survey method by using random sampling technique was used to collect the data from academic staff. Data analysis was conducted by using bivariate correlation and multiple regression analysis. The findings of the result explored that distributive, procedural and performance feedback in the appraisal system are the three significant variables that affect the effectiveness of the performance appraisal system
PARP1 controls KLF4-mediated telomerase expression in stem cells and cancer cells

Abstract Telomerase is highly expressed in cancer and embryonic stem cells (ESCs) and implicated in controlling genome integrity, cancer formation and stemness. Previous studies identified that Krüppel-like transcription factor 4 (KLF4) activates telomerase reverse transcriptase (TERT) expression and contributes to the maintenance of self-renewal in ESCs. However, little is known about how KLF4 regulates TERT expression. Here, we discover poly(ADP-ribose) polymerase 1 (PARP1) as a novel KLF4-interacting partner. Knockdown of PARP1 reduces TERT expression and telomerase activity not only in cancer cells, but also in human and mouse ESCs. Recruitment of KLF4 to TERT promoter is reduced in PARP1-suppressed cells. The poly(ADP-ribose) polymerase activity is dispensable, while the oligo(ADP-ribose) polymerase activity is required for the PARP1- and KLF4-mediated TERT activation. Repression of Parp1 in mouse ESCs decreases expression of pluripotent markers and induces differentiation. These results suggest that PARP1 recruits KLF4 to activate telomerase expression and stem cell pluripotency, indicating a positive regulatory role of the PARP1–KLF4 complex in telomerase expression in cancer and stem cells.
Cardiomyocyte ploidy levels in birds with different growth rates.

Cytofluorimetric study of ploidy levels in ventricular cardiomyocytes was carried out on 36 adult bird species belonging to 10 orders as well as on the quail Coturnix coturnix, of different ages. It was shown that polyploidization of quail cardiomyocytes occurs during the first 40 days after hatching and ends by the time growth is completed. In adult birds, the cardiomyocyte ploidy hardly changed at all. Interspecies comparison revealed that in the adult bird myocardium 2cx2 myocytes are predominant, accounting for at least 50% of the cell population. Multinuclear cells with three to eight diploid nuclei were widespread. The percentage of such cells was five to six times higher in precocial species than in altricial birds of the same weight. Myocytes with polyploid nuclei were rare. A significant interspecies variability of cardiomyocyte ploidy levels was observed. The most prominent differences were found between the precocial and the altricial birds. The mean number of genomes in cells correlated both with the body mass and with the growth rate of the birds. The differences between the precocial and altricial birds disappeared when a statistical method was used to eliminate the effect of the growth rate, but did not when the effect of body mass was eliminated. Among the altricial birds, which are generally immobile during growth, the cardiomyocyte ploidy levels also correlated more closely with growth rate than with body mass. The opposite was observed in the precocial birds, which are highly mobile from the first minutes of life. We conclude that the interspecies variability of bird cardiomyocyte ploidy levels is a result of changes in the balance between the cardiac functional load and the growth rate; this is manifested at the cellular level as a competition between the proliferation and differentiation of cardiomyocytes.

Impacts of aerosol pollutant mitigation on lowland rice yields in China

Aerosol pollution in China is significantly altering radiative transfer processes and is thereby potentially affecting rice photosynthesis and yields. However, the response of rice photosynthesis to aerosol-induced radiative perturbations is still not well understood. Here, we employ a process-based modelling approach to simulate changes in incoming radiation (RAD) and the diffuse radiation fraction (DF) with aerosol mitigation in China and their associated impacts on rice yields. Aerosol reduction has the positive effect of increasing RAD and the negative effect of decreasing DF on rice photosynthesis and yields. In rice production areas where the average RAD during the growing season is lower than 250 W m−2, aerosol reduction is beneficial for higher rice yields, whereas in areas with RAD>250 W m−2, aerosol mitigation causes yield declines due to the associated reduction in the DF, which decreases the light use efficiency. As a net effect, rice yields were estimated to significantly increase by 0.8%–2.6% with aerosol concentrations reductions from 20 to 100%, which is lower than the estimates obtained in earlier studies that only considered the effects of RAD. This finding suggests that both RAD and DF are important processes influencing rice yields and should be incorporated into future assessments of agricultural responses to variations in aerosol-induced radiation under climate change.
Antimicrobial Activity of Kaurane Diterpenes against Oral Pathogens

Two kaurane diterpenes, ent-kaur-16(17)-en-19-oic acid (KA) and 15-β-isovaleryloxy-entkaur- 16(17)-en-19-oic acid (KA-Ival), isolated from Aspilia foliacea, and the methyl ester derivative of KA (KA-Me) were evaluated against oral pathogens. KA was the most active compound, with MIC values of 10 μg mL-1 against the following microorganisms: Streptococcus sobrinus, Streptococcus mutans, Streptococcus mitis, Streptococcus sanguinis, and Lactobacillus casei. However, KA did not show significant activity against Streptococcus salivarius and Enterococcus faecalis, with MIC values equal to 100 and 200 μg mL-1, respectively. Our results show that KA has potential to be used as a prototype for the discovery of new effective anti-infection agents against microorganisms responsible for caries and periodontal diseases. Moreover, these results allow to conclude that minor structural differences among these diterpenes significantly influence their antimicrobial activity, bringing new perspectives to studies on the structure-activity relationship of this type of metabolites with respect to caries and periodontal diseases.
Exploration of Inorganic C and N Assimilation by Soil Microbes with Time-of-Flight Secondary Ion Mass Spectrometry

ABSTRACT Stable C and N isotopes have long been used to examine properties of various C and N cycling processes in soils. Unfortunately, relatively large sample sizes are needed for accurate gas phase isotope ratio mass spectrometric analysis. This limitation has prevented researchers from addressing C and N cycling issues on microbially meaningful scales. Here we explored the use of time-of-flight secondary ion mass spectrometry (TOF-SIMS) to detect 13C and 15N assimilation by individual bacterial cells and to quantify N isotope ratios in bacterial samples and individual fungal hyphae. This was accomplished by measuring the relative abundances of mass 26 (12C14N−) and mass 27 (13C14N− and 12C15N−) ions sputtered with a Ga+ probe from cells adhered to an Si contact slide. TOF-SIMS was successfully used to locate and quantify the relative 15N contents of individual hyphae that grew onto Si contact slides in intimate contact with a model organomineral porous matrix composed of kaolin, straw fragments, and freshly deposited manure that was supplemented with 15NO3−. We observed that the 15N content of fungal hyphae grown on the slides was significantly lower in regions where the hyphae were influenced by N-rich manure than in regions influenced by N-deficient straw. This effect occurred over distances of tens to hundreds of microns. Our data illustrate that TOF-SIMS has the potential to locate N-assimilating microorganisms in soil and to quantify the 15N content of cells that have assimilated 15N-labeled mineral N and shows promise as a tool with which to explore the factors controlling microsite heterogeneities in soil.
Silastic Splints Reduce Middle Meatal Adhesions after Endoscopic Sinus Surgery

Background Adhesions frequently form between the middle turbinate and lateral nasal wall after endoscopic sinus surgery (ESS) and are a possible cause for surgical failure. Many absorbable and nonabsorbable spacers have been tried to improve healing. This study was designed to ascertain whether placement of a thin silastic splint into the middle meatus after sinus surgery for 2 weeks reduces adhesion formation and whether a reduction in the adhesion rate improves patient outcomes in the early postoperative phase. Methods Forty-two patients who were scheduled to undergo ESS for chronic rhinosinusitis were randomized to have a silastic splint placed into the middle meatus on one side of the nose but not the other at the completion of surgery. Splints were removed 2 weeks postoperatively. Symptom scores were recorded for each side of the nose up to 12 weeks after surgery and ethmoid cavities were graded at the 6- and 12-week visits along with assessment of adhesions. Patients were blinded to which side was splinted as was the surgeon assessing ethmoid cavities at 6 and 12 weeks. Results Thirty-three patients completed 12 weeks of follow-up. Nasal obstruction and facial pain/discomfort were significantly higher on splinted sides for the first 2 weeks. More interventions were performed to debride adhesions in nonsplinted sides. Endoscopy revealed no adhesions at 12 weeks for sides treated with a splint whereas 9 of 33 nonsplinted sides had persistent adhesions. There were no significant differences in symptom or ethmoid cavity scores at 6 or 12 weeks between sides treated with splints versus sides treated without splints or between sides with adhesions versus without adhesions. Conclusion Middle meatal silastic splints reduce adhesions after ESS but increase early nasal obstruction and discomfort. Their use did not significantly change symptom or ethmoid cavity scores at 12 weeks.
Activity of a novel bcl-2/bcl-xL-bispecific antisense oligonucleotide against tumors of diverse histologic origins.

BACKGROUND Increased expression of the anti-apoptotic proteins Bcl-2 and Bcl-xL is involved in the development and progression of many tumors. We recently reported that the bcl-2/bcl-xL-bispecific antisense oligonucleotide 4625 induces apoptosis in lung carcinoma cells. To further assess the therapeutic potential of oligonucleotide 4625, we investigated its effect on a series of human tumor cell lines of diverse histologic origins in vitro and in vivo. METHODS Oligonucleotide 4625-mediated inhibition of bcl-2 and bcl-xL expression in vitro was measured in breast carcinoma cells with the use of reverse transcription-polymerase chain reaction (PCR), real-time PCR, and western blotting. Cytotoxicity was assessed in several different cell lines by measurement of tumor cell growth, propidium iodide uptake, and nuclear apoptosis. The in vivo activity of oligonucleotide 4625 was determined by the inhibition of growth of established tumor xenografts in nude mice, immunohistochemical staining of Bcl-2 and Bcl-x proteins in the tumors, and western blotting of tumor lysates. Apoptosis in tumor xenografts was detected with the use of in situ TUNEL (i.e., terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-digoxigenin nick end labeling) staining. All statistical tests are two-sided. RESULTS In breast carcinoma cells, oligonucleotide 4625 treatment reduced bcl-2 and bcl-xL messenger RNA levels in a dose-dependent manner. At 600 nM:, oligonucleotide 4625 reduced Bcl-2 and Bcl-xL protein levels to 25% (95% confidence interval [CI] = 16% to 34%) and 20% (95% CI = 14% to 26%), respectively, of the levels in untreated cells and it decreased viability in all cell lines mainly by inducing apoptosis. In vivo, oligonucleotide 4625 statistically significantly inhibited the growth of breast and colorectal carcinoma xenografts by 51% (95% CI = 28% to 74%) and 59% (95% CI = 44% to 74%), respectively, relative to those treated with control oligonucleotide 4626; it also reduced Bcl-2 and Bcl-xL protein levels and induced tumor cell apoptosis. CONCLUSION The bcl-2/bcl-xL-bispecific antisense oligonucleotide 4625 merits further study as a novel compound for cancer therapy.
Capital regulation, competition and risk-taking behavior of Indian banks in a simultaneous approach

Purpose - The purpose of this paper is to investigate the association between capital regulation and risk-taking behavior of Indian banks after incorporating the influence of competition. Further, the study intends to enrich the existing literature by providing empirical evidence on the role of human resources in managing risk along with the influence of other bank specific and macroeconomic variables. Design/methodology/approach - Secondary data on 39 listed Indian commercial banks are collected from “Capitaline Plus” corporate data database for a period of 15 years. Capital is measured by capital adequacy ratio as defined by the regulators, and two definitions of risk – credit risk and insolvency risk – are employed. Competition is measured by Herfindahl-Hirschman deposits index, concentration ratio and Findings - The study finds that absolute level of regulatory capital and bank risk are positively associated, although the influence of capital on risk is not statistically significant. The influence of competition on risk is negative for all the models, which supports the “competition stability” view. The impact of human capital on bank risk is also negative for all cases. Practical implications - The findings of the study are useful for the decision makers in several ways based on the inverse influence of competition and HCE on bank risk. Further, the observed positive association between capital and risk indicates that the capital regulation is not sufficient to enhance the stability in the banking sector. Originality/value - This is the first study in the Indian context that incorporates the competition in the banking industry as an explanatory variable in the extant bank capital and risk relationship.
DUDes: a top-down taxonomic profiler for metagenomics

MOTIVATION Species identification and quantification are common tasks in metagenomics and pathogen detection studies. The most recent techniques are built on mapping the sequenced reads against a reference database (e.g. whole genomes, marker genes, proteins) followed by application-dependent analysis steps. Although these methods have been proven to be useful in many scenarios, there is still room for improvement in species and strain level detection, mainly for low abundant organisms. RESULTS We propose a new method: DUDes, a reference-based taxonomic profiler that introduces a novel top-down approach to analyze metagenomic Next-generation sequencing (NGS) samples. Rather than predicting an organism presence in the sample based only on relative abundances, DUDes first identifies possible candidates by comparing the strength of the read mapping in each node of the taxonomic tree in an iterative manner. Instead of using the lowest common ancestor we propose a new approach: the deepest uncommon descendent. We showed in experiments that DUDes works for single and multiple organisms and can identify low abundant taxonomic groups with high precision. AVAILABILITY AND IMPLEMENTATION DUDes is open source and it is available at http://sf.net/p/dudes SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.

An Automated, Parallel Processing Approach to Biomolecular Sample Preparation

Sample preparation for DNA and RNA assays is a prime candidate for laboratory automation. A novel, parallel processing device that performs the three separate liquid-handling functions necessary for such sample preparation—dispensing, pipetting, and pressurizing—is presented. The device comprises an array of fine nozzles connected by fluidic channels to automatically and precisely distribute flow between one source and an array of points. The design principles, as well as the experimental and computational methods used to develop the device, are described. Test results, including accuracy, uniformity, volume range, and timing, are presented. The functionality of the device is demonstrated by performing a solid-phase extraction of DNA with two types of microcolumns.
Effects of matched weight loss from calorie restriction, exercise, or both on cardiovascular disease risk factors: a randomized intervention trial.

BACKGROUND Weight loss from calorie restriction (CR) and/or endurance exercise training (EX) is cardioprotective. However CR and EX also have weight loss-independent benefits. OBJECTIVE We tested the hypothesis that weight loss from calorie restriction and exercise combined (CREX) improves cardiovascular disease (CVD) risk factors more so than similar weight loss from CR or EX alone. DESIGN Overweight, sedentary men and women (n = 52; aged 45-65 y) were randomly assigned to undergo 6-8% weight loss by using CR, EX, or CREX. Outcomes were measured before and after weight loss and included maximal oxygen consumption (VO2max), resting blood pressure, fasting plasma lipids, glucose, C-reactive protein, and arterial stiffness [carotid-femoral pulse wave velocity (PWV) and carotid augmentation index (AI)]. Values are means ± SEs. RESULTS Reductions in body weight (∼7%) were similar in all groups. VO2max changed in proportion to the amount of exercise performed (CR, -1% ± 3%; EX, +22% ± 3%; and CREX, +11% ± 3%). None of the changes in CVD risk factors differed between groups. For all groups combined, decreases were observed for systolic and diastolic blood pressure (-5 ± 1 and -4 ± 1 mm Hg, respectively; both P < 0.0008), total cholesterol (-17 ± 4 mg/dL; P < 0.0001), non-HDL cholesterol (-16 ± 3 mg/dL; P < 0.0001), triglycerides (-18 ± 8 mg/dL; P = 0.03), and glucose (-3 ± 1 mg/dL; P = 0.0003). No changes were observed for HDL cholesterol (P = 0.30), C-reactive protein (P = 0.10), PWV (P = 0.30), or AI (P = 0.84). These changes would be expected to decrease the lifetime risk of CVD from 46% to 36%. CONCLUSION Matched weight losses from CR, EX, and CREX have substantial beneficial effects on CVD risk factors. However, the effects are not additive when weight loss is matched. This trial was registered at clinicaltrials.gov as NCT00777621.
The Acute Dialysis Quality Initiative--part II: patient selection for CRRT.

The delivery of optimal acute dialytic support requires that the correct patients be selected for such treatment in a timely fashion and that such treatment be delivered at the appropriate dose, for an appropriate length of time, and for the appropriate indications. The Acute Dialysis Quality Initiative sought to address these issues through an expert-enhanced review of the literature. This article represents a condensation of its findings with regard to patients selection for CRRT, indications for initiation of treatment, transition to other treatments, cessation of treatment, and availability of continuous therapy. The article offers recommendations for clinical practice based on the findings of the expert group. It also offers suggestions and sets priorities for future research in this important area of critical care nephrology.
