Pectobacterium carotovorum (Pc) is a phytopathogenic strain that causes soft rot disease in potato (Solanum tuberosum L.), resulting in postharvest losses. Chemical control is effective for managing this disease, but overdoses cause adverse effects. Because farmers insist on using chemical agents for crop protection, it is necessary to develop more effective pesticides in which the active compound released can be regulated. In this context, we proposed the synthesis of ZnAl-NADS, in which nalidixic acid sodium salt (NADS) is linked to a ZnAl-NO3 layered double hydroxide (LDH) host as a nanocarrier...

Sewage sludge (SS) obtained after sewage treatment process may contain several toxic substances. Bioremediation can decrease the toxicity of the sludge, mainly when it is associated with stimulant agents, such as sugarcane bagasse (B). Samples of pure SS (SSP); SS+B; SS+Soil; and SS+B+Soil were bioremediated for 1, 3, and 6 months (T1, T2, and T3, respectively). After each period, the cytotoxic, genotoxic, and mutagenic potentials of the solid samples and their respective aqueous extracts (aqueous eluate and percolate water) were evaluated by the Allium cepa test...

Alain Segundo Potts, Christiam Segundo Morales Alvarado, Claudio Garcia
The detection of no-model input-output (IO) pairs is important because it can speed up the multivariable system identification process, since all the pairs with null transfer functions are previously discarded and it can also improve the identified model quality, thus improving the performance of model based controllers. In the available literature, the methods focus just on the open-loop case, since in this case there is not the effect of the controller forcing the main diagonal in the transfer matrix to one and all the other terms to zero...

The present study aimed to evaluate the activity of methanolic extract of Rubus ulmifolius Schott against the Acanthamoeba castellani Neff Strain as well as its antioxidant and antimicrobial effects. The tested extract has a good amoebicidal activity with low IC50 (61.785 ± 1.322 μg/ml) and also has significant activity against both Gram-positive (S. aureus, S. agalactiae) and Gram-negative bacteria (E. coli, S. typhimurium) and against C. albicans. The inhibition zones diameters (IZD) and minimal inhibitory concentration (MIC) values were in the range of 22...

In order to promote a local Tunisian product, this study was designed to examine, for the first time, the anti-Acanthamoeba activity (Acanthamoeba castellanii Neff) of the essential oils of Tunisian Citrus sinensis peels (Maltese half-blood) and the effect of viroid plant infection on this activity. To do so, three samples of peels' essential oils were studied: from a healthy plant (Control), a plant inoculated with Citrus exocortis viroid (CEVd) and one inoculated with hot stunt cachexia viroid (HSVd). The samples were extracted by hydrodistillation from dried peels and characterized by GC-MS...

The present study tested 80 samples of municipal, geothermal and recreational water samples for the occurrence of waterborn free living amoebae (FLA) including Acanthamoeba, Balamuthia mandrillaris, Vahlkampfiids and Vermamoeba in Semnan province, North half of Iran. Four sets of primers including JDP1,2 primers, ITS1,2 primers (Vahlkampfiids), 16S rRNABal primers (Balamuthia mandrillaris) and NA1,2 primers (Vermamoeba) were used to confirm the morphological identification. From the 80 water samples tested in the present study, 16 (20%) were positive for the outgrowth of free living amoebae based on the morphological page key...

Acanthamoeba is an opportunistic pathogen which is the causal agent of a sight-threatening ulceration of the cornea known as Acanthamoeba keratitis (AK) and, more rarely, an infection of the central nervous system called "granulomatous amoebic encephalitis" (GAE). The symptoms of AK are non-specific, and so it can be misdiagnosed as a viral, bacterial, or fungal keratitis. Furthermore, current therapeutic measures against AK are arduous, and show limited efficacy against the cyst stage of Acanthamoeba. 1H-Phenalen-1-one (PH) containing compounds have been isolated from plants and fungi, where they play a crucial role in the defense mechanism of plants...

A new paper-based lateral flow immunoassay configuration was engineered and investigated. The assay is intended for the detection of a model protein in human serum, that is, human immunoglobulin G, with the aim to demonstrate a virtually universal protein detection platform. Once the sample is added in the strip, the analyte is selectively captured by antibody-decorated silica beads (Ab-SiO2) onto the conjugate pad and the sample flows by capillarity throughout the strip until reaching the test line, where a sandwich-like immunocomplex takes place due to the presence of antibody-functionalized QDs (Ab-QDs) onto the test line...

The use of hydroxychloroquine (HCQ) in Primary Sjögren's Syndrome (pSS) has been assessed in different studies over the last years, with conflicting results regarding its efficacy in sicca syndrome and extraglandular manifestations (EGM). The goal of this study was to compare the incidence rate of EGM in pSS patients with and without HCQ therapy.We performed a multicenter retrospective study, including patients with pSS (European classification criteria) with at least 1 year of follow-up. Subjects with concomitant fibromyalgia, autoimmune hepatitis, primary biliary cirrhosis, and primary sclerosing cholangitis were excluded...

BACKGROUND: Decision-making on postings and transfers - that is, the geographic deployment of the health workforce - is a key element of health workforce governance. When poorly managed, postings and transfers result in maldistribution, absenteeism, and low morale. At stake is managing the balance between organisational (i.e., health system) and individual (i.e., staff preference) needs. The negotiation of this potential convergence or divergence of interests provides a window on practices of postings and transfers, and on the micro-practices of governance in health systems more generally...

Background: In a significant percentage of advanced non-small-cell lung cancer (NSCLC) patients, tumor tissue is unavailable or insufficient for genetic analyses. We prospectively analyzed if circulating-free DNA (cfDNA) purified from blood can be used as a surrogate in this setting to select patients for treatment with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Patients and methods: Blood samples were collected in 119 hospitals from 1138 advanced NSCLC patients at presentation (n = 1033) or at progression to EGFR-TKIs (n = 105) with no biopsy or insufficient tumor tissue...

The paper asks the question whether Kant's ethical theory can be applied to issues in assisted reproductive technology (ART). It argues against three objections to applying Kant's ethics to ART: (i) the non-identity objection, (ii) the gen-ethics objection, and (iii) the care-ethics objection. After showing that neither of the three objections is sufficiently persuasive the paper proposes a reading of Kant's 'formula of humanity,' and especially its negative clause (i.e., the 'merely as means' clause), that can be of some guidance in ART...

Recent research suggests that self-righteousness is bounded, arising more reliably in evaluations of immoral actions than in evaluations of moral actions. Here, we test four implications of this asymmetry in self-righteousness and the mechanism explaining it. We find that people are less likely to make negative character inferences from their own unethical behavior than from others' unethical behavior (Experiment 1), believe they would feel worse after an unethical action than others (Experiment 2), and believe they are less capable of extreme unethical behavior than others (Experiment 3)...

Seasonal affective disorder (SAD) is a recurrent depressive disorder with a seasonal pattern. In addition to some specific symptoms such as sad mood, low energy or carbohydrate craving, this mood disorder is also characterized by the presence of sleeping problems and alcohol disorders. Interestingly, there is a strong link between alcohol use and sleeping deficits. Although previous studies have focused extensively on the sleep patterns in SAD patients and patients with alcohol use disorder (AUD), no research has yet been conducted on subjects with comorbid SAD and AUD...

Moral decision-making depends on the interaction between automatic emotional responses and rational cognitive control. A natural emotional regulator state seems to be sleep, in particular rapid eye movement (REM) sleep. We tested the impact of daytime sleep, either with or without REM, on moral decision. Sixty participants were presented with 12 sacrificial (6 Footbridge- and 6 Trolley-type) and 8 everyday-type moral dilemmas at 9 AM and at 5 PM. In sacrificial dilemmas, participants had to decide whether or not to kill one person to save more people (utilitarian choice), and to judge how morally acceptable the proposed choice was...

This study compared the effects of two velocity loss thresholds during a power-oriented resistance training program on the mechanical capacities of lower-body muscles. Twenty men were counterbalanced in two groups (VL10 and VL20) based on their maximum power capacity. Both groups used the same exercises, relative intensity and repetition volume, only differing in the velocity loss threshold of each set (VL10: 10% vs. VL20: 20%). Pre- and post-training assessments included an incremental loading test and a 15-m linear sprint to assess the force- and load-velocity relationships and athletic performance variables, respectively...

Suspected allergy to penicillins and cephalosporins is very common in childhood. After a proper evaluation, allergy will be confirmed only in a small portion of them. Intradermal tests are usually part of the allergy workup, but they are painful for children and time-consuming, and their role has been debated. A systematic review found only two studies reporting a positive predictive value of skin tests in children of 36% and 33%, respectively, leading to a high rate of inaccurate diagnosis. Moreover, considering that skin tests are negative in more than 90-95% of cases, an oral provocation test (OPT) is finally needed to confirm tolerance in most of these children...

Moral norms are fundamental for virtually all social interactions, including cooperation. Moral norms develop and change, but the mechanisms underlying when, and how, such changes occur are not well-described by theories of moral psychology. We tested, and confirmed, the hypothesis that the commonness of an observed behavior consistently influences its moral status, which we refer to as the common is moral (CIM) heuristic. In 9 experiments, we used an experimental model of dynamic social interaction that manipulated the commonness of altruistic and selfish behaviors to examine the change of peoples' moral judgments...

We brought together various lines of work on motivation, morality, and doping by testing a theory-based model prospectively linking contextual and personal motivational variables, moral attitudes, moral disengagement in doping, doping intentions, and doping use. Participants were 257 Greek athletes who completed a questionnaire pack at the beginning of a sport season. In the case of doping use, we also obtained data close to the end of the same season. The model showed that perceptions of controlling coach behaviors predicted athlete need frustration, which in turn predicted low moral functioning and doping intentions/doping use...
