Agile Architecture Based on ISA-88 for the Design of Execution Control Chart in Distributed Applications using IEC-61499

Nowadays, industrial automation systems must optimize control techniques and communication integration of their processes, to introduce concepts given by Industry 4.0. To achieve this, it is necessary to introduce new automation standards to achieve agile and intelligent manufacturing systems, this is the reason why the IEC-61499 standard is considered as the main option. In an industrial level, the ISA-88 standard offers a coherent set of rules and terminology for batch digital control and it defines models for this kind of industries. This is why it is necessary to contribute with low cost alternatives to the industry with which it can implement the Industry 4.0 concepts in various control systems. The present working paper proposes the development of Function Blocks (FBs) networks under IEC-61499 standard to integrate distributed control systems with the help of embedded hardware using the ISA-88 standard as a basis for the development of control algorithms and FB’s Execution Control Chart (ECC)

Analysis of the denitrification pathway and greenhouse gases emissions in Bradyrhizobium sp. strains used as biofertilizers in South America

Aims Greenhouse gases are considered potential atmospheric pollutants, with agriculture being one of the main emission sources. The practice of inoculating soybean seeds with Bradyrhizobium sp. might contribute to nitrous oxide (N2O) emissions. We analyzed this capacity in five of the most used strains of Bradyrhizobium sp. in South America. Methods and Results We analyzed the denitrification pathway and N2O production by B. japonicum E109 and CPAC15, B. diazoefficiens CPAC7, and B. elkanii SEMIA 587 and SEMIA 5019, both in free‐living conditions and symbiosis with soybean. The in silico analysis indicated the absence of nosZ genes in B. japonicum and the presence of all denitrification genes in B. diazoefficiens strains, as well as the absence of nirK, norC and nosZ genes in B. elkanii. The in planta analysis confirmed the N2O production under saprophytic conditions or symbiosis with soybean roots nodules. In the last case up to 26·1 and 18·4 times higher in plants inoculated with SEMIA5019 and E109 respectively, than in those inoculated with USDA110. Conclusions The strains E109, SEMIA 5019, CPAC15 and SEMIA 587 showed the highest N2O production both as free‐living cells and in symbiotic conditions in comparison with USDA110 and CPAC7, which do have the nosZ gene. Although norC and nosZ could not be identified in silico or in vitro in SEMIA 587 and SEMIA 5019, these strains showed capacity to produce N2O in our experimental conditions. Significance and Impact of Study This is the first report to analyze and confirm the incomplete denitrification capacity and N2O production in four of the five most used strains of Bradyrhizobium sp. for soybean inoculation in South America.Fil: Obando Castellanos, Dolly Melissa.

Reconstructive Breast Surgery: When to Perform, Techniques and Medical Factors

La reconstrucción mamaria después de una mastectomía es un aspecto crucial del tratamiento del cáncer de mama que busca restaurar la imagen corporal, mejorar la calidad de vida y abordar aspectos emocionales de las pacientes. Por lo que se planea definir cuando es el momento adecuado para realizar la cirugía, conocer las nuevas técnicas quirúrgicas y los factores médicos que pueden incidir en el procedimiento, el cual presentan pocas complicaciones y no identifican factores de riesgo para la recidiva y el fallecimiento de las pacientes intervenidas. Es evidente que la elección del tipo de reconstrucción debe basarse en una evaluación exhaustiva de la anatomía del paciente, el estado de salud general, la etapa del cáncer y las preferencias individuales; en las que se debe identificar si se realiza un abordaje inmediato o posterior; con el uso de colgajo TRAM o colgajo DIEP. Cada vez más mujeres optan por este procedimiento por lo que ya no es suficiente alcanzar únicamente las metas oncológicas, sino también la satisfacción estética.Breast reconstruction after a mastectomy is a crucial aspect of breast cancer treatment that seeks to restore body image, improve quality of life, and address emotional aspects of patients. Therefore, it is planned to define when is the right time to perform the surgery, to know the new surgical techniques and the medical factors that can affect the procedure, which presents few complications and does not identify risk factors for recurrence and death. the patients undergoing surgery. Clearly, the choice of type of reconstruction should be based on a thorough evaluation of the patient's anatomy, general health, stage of cancer, and individual preferences; in which it must be identified whether an immediate or subsequent approach is carried out; with the use of TRAM flap or DIEP flap. More and more women are opting for this procedure, so it is no longer enough to achieve only oncological goals, but also aesthetic satisfaction

Maternal and neonatal data collection systems in low- and middle-income countries: Scoping review protocol

Background: Pregnant women and neonates represent one of the most vulnerable groups, especially in low- and middle-income countries (LMICs). A recent analysis reported that most vaccine pharmacovigilance systems in LMICs consist of spontaneous (passive) adverse event reporting. Thus, LMICs need effective active surveillance approaches, such as pregnancy registries. We intend to identify currently active maternal and neonatal data collection systems in LMICs, with the potential to inform active safety electronic surveillance for novel vaccines using standardized definitions. Methods: A scoping review will be conducted based on established methodology. Multiple databases of indexed and grey literature will be searched with a specific focus on existing electronic and paper-electronic systems in LMICs that collect continuous, prospective, and individual-level data from antenatal care, delivery, neonatal care (up to 28 days), and postpartum (up to 42 days) at the facility and community level, at the national and district level, and at large hospitals. Also, experts will be contacted to identify unpublished information on relevant data collection systems. General and specific descriptions of Health Information Systems (HIS) extracted from the different sources will be combined and duplicated HIS will be removed, producing a list of unique statements. We will present a final list of Maternal, Newborn, and Child Health systems considered flexible enough to be updated with necessary improvements to detect, assess and respond to safety concerns during the introduction of vaccines and other maternal health interventions. Selected experts will participate in an in-person consultation meeting to select up to three systems to be further explored in situ. Results and knowledge gaps will be synthesized after expert consultation.Fil: Berrueta, Mabel. Instituto de Efectividad Clínica y Sanitaria; ArgentinaFil: Bardach, Ariel Esteban.

Niraparib in patients with metastatic castration-resistant prostate cancer and DNA repair gene defects (GALAHAD): a multicentre, open-label, phase 2 trial

Background Metastatic castration-resistant prostate cancers are enriched for DNA repair gene defects (DRDs) that can be susceptible to synthetic lethality through inhibition of PARP proteins. We evaluated the anti-tumour activity and safety of the PARP inhibitor niraparib in patients with metastatic castration-resistant prostate cancers and DRDs who progressed on previous treatment with an androgen signalling inhibitor and a taxane. Methods In this multicentre, open-label, single-arm, phase 2 study, patients aged at least 18 years with histologically confirmed metastatic castration-resistant prostate cancer (mixed histology accepted, with the exception of the small cell pure phenotype) and DRDs (assessed in blood, tumour tissue, or saliva), with progression on a previous next-generation androgen signalling inhibitor and a taxane per Response Evaluation Criteria in Solid Tumors 1.1 or Prostate Cancer Working Group 3 criteria and an Eastern Cooperative Oncology Group performance status of 0–2, were eligible. Enrolled patients received niraparib 300 mg orally once daily until treatment discontinuation, death, or study termination. For the final study analysis, all patients who received at least one dose of study drug were included in the safety analysis population; patients with germline pathogenic or somatic biallelic pathogenic alterations in BRCA1 or BRCA2 (BRCA cohort) or biallelic alterations in other prespecified DRDs (non-BRCA cohort) were included in the efficacy analysis population. The primary endpoint was objective response rate in patients with BRCA alterations and measurable disease (measurable BRCA cohort). This study is registered with ClinicalTrials.gov, NCT02854436. Findings Between Sept 28, 2016, and June 26, 2020, 289 patients were enrolled, of whom 182 (63%) had received three or more systemic therapies for prostate cancer. 223 (77%) of 289 patients were included in the overall efficacy analysis population, which included BRCA (n=142) and non-BRCA (n=81) cohorts. At final analysis, with a median follow-up of 10·0 months (IQR 6·6–13·3), the objective response rate in the measurable BRCA cohort (n=76) was 34·2% (95% CI 23·7–46·0). In the safety analysis population, the most common treatment-emergent adverse events of any grade were nausea (169 [58%] of 289), anaemia (156 [54%]), and vomiting (111 [38%]); the most common grade 3 or worse events were haematological (anaemia in 95 [33%] of 289; thrombocytopenia in 47 [16%]; and neutropenia in 28 [10%]). Of 134 (46%) of 289 patients with at least one serious treatment-emergent adverse event, the most common were also haematological (thrombocytopenia in 17 [6%] and anaemia in 13 [4%]). Two adverse events with fatal outcome (one patient with urosepsis in the BRCA cohort and one patient with sepsis in the non-BRCA cohort) were deemed possibly related to niraparib treatment. Interpretation Niraparib is tolerable and shows anti-tumour activity in heavily pretreated patients with metastatic castration-resistant prostate cancer and DRDs, particularly in those with BRCA alterations

Optimized amylolytic enzymes production in Saccharomycopsis fibuligera DSM-70554: An approach to efficient cassava starch utilization

Different nutritional and operative conditions for improving amylolytic enzyme production by the amylolytic yeast Saccharomycopsis fibuligera DSM-70554 were evaluated. Under selected conditions, cassava starch could be efficiently utilized. Culture conditions such as oxygen saturation (50% dissolved oxygen tension), temperature (34 °C) and pH (5.5) showed a significant influence on α-amylase and glucoamylase production. An optimized culture medium (OPT) formulated by the chemostat pulse-shift method, containing yeast extract as the most favorable organic nitrogen source, vitamins and certain salts (MgCl2, MnSO4, CaCl2) allowed to achieve the highest amylolytic enzyme production, thus leading to an optimal liquefaction and saccharification of cassava starch. Tween 80 (0.2–1% w/v) demonstrated to be a favorable amendment for amylolytic enzyme production. Under the conditions herein described, a 97% degradation of cassava starch could be finally attained under batch culture mode. Maximal values of 633.3 U L−1 h−1 of α-amylase and 72.1 U L−1 h−1 of glucoamylase under optimized conditions represented ∼9 and ∼3-fold increments, respectively, as compared to preliminary fermentation assays under non-optimal conditions.Fil: Gonzalez, Claudio Fabricio.

A critical assessment of a viscometric assay for measuring Saccharomycopsis fibuligera α-amylase activity on gelatinised cassava starch

A viscometric technique for measuring Saccharomycopsis fibuligera DSM-70554 α-amylase on gelatinised cassava starch aqueous solutions was assessed. The selected conditions for working over a reliable viscosity measurement range involved a starch concentration of 5% (w/v) and a shear rate of 0.168 1/s. Viscometric assay involved the determination of the slope of the decrease in viscosity with time of the starch solution consequent on enzyme addition. Thereafter, a calibration curve was constructed by plotting the slopes, expressed in arbitrary viscometric units (AVU), versus the corresponding absolute activity (in IU) of either the commercial α-amylase from Aspergillus oryzae (up to 0.1 IU) or the S. fibuligera DSM-70554 α-amylase (up to ca. 0.4 IU). The amount of enzyme expressed in absolute terms produced different liquefying activities according to the α-amylase tested, emphasising the necessity of this correlation to be carried out for the particular enzyme being measured. In this work, a linear relationship and a very good correlation factor were achieved for the calibration of both amylases. Likewise, α-amylase activities determined according to the conventional reducing sugar determination and the colorimetric assay with iodine were proportional to those viscometrically obtained, both for A. oryzae and S. fibuligera α-amylase, validating conversions between different units. The viscometric assay herein described showed to be specific and sensitive and, after its calibration, it allows to convert α-amylase measurements in absolute units thus facilitating future comparisons.Fil: Gonzalez, Claudio Fabricio.

The importance of denitrification performed by nitrogen-fixing bacteria used as inoculants in South America

Replacing synthetic fertilizers by biological nitrogen fixation (BNF) is regarded as an environmentally sound practice, but some diazotrophic bacteria are capable of emitting N2O by denitrification. The ability to use nitrate represents an ecological advantage for the survival of some microorganisms under O2-limiting conditions, but may contribute to increased N2O emissions. Scope The importance of denitrification performed by N2-fixing bacteria used as inoculants in South America is discussed, especially the possibility of these bacteria act as N2O source or sink. Conclusions There is no doubt of the importance of BNF as a sustainable N source for plants. Through genome investigation, we demonstrated that some strains widely used as inoculants for BNF harbor the entire denitrification pathway to reduce nitrate to N2. Others contain none, or only some of the denitrification genes, resulting in complete absence of denitrification or production of intermediates such as NO2−, NO or N2O. Evidence of differential effects of bacterial strains on soil N2O were reported, but more studies are still needed to affirm crop inoculation can be a driver for source or sink of this gas. Finally, considerations were made about BNF as an indispensable resource to indirectly mitigate greenhouse gas emissions in agroecosystems.Fil: Zilli, Jerri Édson.

Previous Incubation of Bradyrhizobium japonicum E109 and Azospirillum argentinense Az39 (formerly A. brasilense Az39) Improves the Bradyrhizobium-Soybean Symbiosis

The aim of this work was to evaluate under diverse plant growth conditions the previous incubation between B. japonicum E109 (BjE109) and A. argentinense Az39 (AaAz39) and elucidate their impact on the Bradyrhizobium-soybean symbiosis and plant growth. Five treatments were performed: (i) uninoculated seeds; (ii) seeds inoculated with BjE109; (iii) seeds inoculated with AaAz39; (iv) seeds co-inoculated at the seeds sowing with equal volume (1:1) of BjE109 and AaAz39; and (v) seeds inoculated with equal volume (1:1) of BjE109 and AaAz39 24 h before seed sowing. Each treatment was assessed through a seed recovery assay, glasshouse assays, and field assays. The single plant level differences were achieved under greenhouse conditions while differences at population level (crop) were achieved by a field assay. The previous incubation between BjE109 and AaAz39 improved the ability of BjE109 to survive on soybean seeds with 25% and 10% of cell recovery at 4 h and 6 days post-inoculation respectively. As a result of the greater bacterial survival, the symbiosis parameters like nodule number, size, and biomass and nodulation percentage also significantly increased. In agreement with these observations, the grain yield under field conditions showed 13.3 and 17.3% greater than immediate combination or single BjE109 inoculation respectively. The previous incubation between BjE109 and AaAz39 24 h before their inoculation improves the Bradyrhizobium-soybean symbiosis and increases both plant growth under culture controlled and crop productivity under field conditions, in comparison with the single inoculation with BjE109 or the immediate inoculation using both strains.Fil: Torres, Daniela Soledad.
