Viability and Colony Morphology Variation of Rhodococcus rhodochrous CNMN-Ac-05 in the Presence of Magnetite Nanoparticles

In recent decades the use of nanotechnologies in the remediation of xenobiotic substances has proven its effectiveness, but not its safety. Nanoparticles often accumulate in the remedied environment, having, over time, toxic effects on living organisms. In this context, research on the vital activity of microorganisms and their interaction with nanoparticles is of major importance. Aim of the research was to determine the influence of Fe3O4 nanoparticles, obtained by different ways (laboratory method and synthesis in the reactor) on the viability and colony morphology of Rhodococcus rhodochrous CNMN-Ac-05 strain. Methods. Encapsulated magnetite (Fe3O4) nanoparticles were synthesized by chemical co-precipitation method, using iron(II) sulfate and iron(III) chloride in the presence of poly-N-vinylpyrrolidone, used as a stabilizer. Fe3O4 SR (Synthesis in the Reactor) was produced in the multifunctional reactor VGR-50, at the same conditions. Cell biomass was determined on the spectrophotometer by the optical density at 540 nm,with subsequent recalculation to cell dry weight according to the calibration curve. The cell dry weight was determined by gravimetric method. The morphological features of the rhodococci colonies were described according to the standard microbiological method. Results. It was established that magnetite nanoparticles in concentrations of 1–100 mg/L were not toxic to the R. rhodochrous strain, had a positive effect on the viability of rhodococci by stimulating the growth of biomass, regardless of their concentration and the method of their synthesis. In the presence of Fe3O4 nanoparticles the population dissociated to S1, S2, R1, R2 forms, and S-R type of colonies, while the basic morphological features of R. rhodochrous colonies corresponded to type S1. Conclusions. The optimal concentration of magnetite nanoparticles, which stimulated the growth and development of R. rhodochrous was 25 mg/L for Fe3O4 and 50 mg/L Fe3O4 SR. At all concentration of Fe3O4 nanoparticles the main colony morphotype of the rhodococci was smooth S1-type; the new types of colonies represented only 0.1–0.6% of the population, and the lowest degree of variability corresponded with the highest colony-forming units index.
‘Having money is not the essential thing . . . but . . . it gets everything moving’: Young Colombians Navigating Towards Uncertain Futures?

In this article, I extend the discussion of aspirations as a conceptual tool by exploring how young Colombians plan to pursue them and by seeking to understand their aspirations as a way of navigating towards what they see as a good life. Drawing upon insights from fieldwork, I use Vigh’s concept of social navigation to emphasise the importance of the social environment, and the available opportunity structures and resources, which shape young people’s aspirations and their ideas of a good life but which, more importantly, influence their navigational strategies to pursue them. I argue that Colombian young people from poor backgrounds do have aspirations and that these go beyond educational and occupational goals. Their aspirations provide information about their desire for a more stable future in an uncertain world but do not necessarily match the opportunities available to them. The young Cartagenians featuring in this study, therefore, struggle to overcome contextual and structural constraints in their social navigation, which is aimed at achieving a good life. I conclude that the young people featured in this study live amid uncertainty about their future and follow a form of doxa in formulating their aspirations. However, while the combination of economic constraints and doxic aspirations that are usually unachievable create barriers to their imagined futures, the young people socially navigate according to the opportunities that emerge and become available to them, to achieve a form of what they perceive as a good life, whereby educational and occupational goals became a means to an end.
Developing the Positive Identity of Minoritized Women Leaders in Higher Education: How can Multiple and Diverse Developers Help With Overcoming the Impostor Phenomenon?

Minoritized women remain underrepresented in leadership positions, especially within higher education (HE). A key barrier to advancement for women of color is their susceptibility to impostor phenomenon (IP). A developmental network where the minoritized woman receives developmental support from multiple individuals is a potentially powerful intervention that can help them advance their careers, but there is a general lack of research on IP in the context of minoritized women’s leadership development and the role of developmental support, especially with regards to multiple diversified developmental relationships. Therefore, this paper integrates various literature streams (leader development for minoritized women in higher education, IP, mentoring) and offers a conceptual framework that utilizes a developmental network perspective. The propositions offered explain how multiple developers can help minoritized women address IP and develop positive leader identities, as well as how both parties can better anticipate and handle challenges related to diversified developmental relationships in HE.
The Acne-treatment Potential of Cinnamomum Camphora Chvar. Borneol Essential Oil in Vitro and in Vivo

Background: Acne is one of the most common chronic inflammatory skin diseases, abnormal proliferation of keratinocytes can block the hair follicle sebaceous glands result in the formation of acne. Most drugs to treat acne can cause a variety of side effects, therefore, it is important to seek natural and safe complementary and alternative therapies.Methods: The inhibitory effects of BEO were determined on the proliferation of human keratinocyte (HaCaT) cells induced by heat-inactivated Staphylococcus epidermidis and release of the inflammatory mediators. Further, a component-target-signal pathway for BEO’s effects on acne was constructed through network pharmacology and the mechanism of BEO action was studied in vivo through the rabbit ear acne model.Results: BEO inhibited both cell proliferation, induced by heat-inactivated Staphylococcus epidermidis (p < 0.0001), and release of the inflammatory mediators TNF-α (p < 0.0001) and IL-1β (p < 0.05) in a dose-dependent manner (r = -0.9952, -0.9492), in a HaCaT cell-model of acne. A network pharmacology analysis of the chemical components of BEO characterized these effects as multi-component, multi-target and multi-pathway. All targets were mainly associated with metabolic pathways, the toll-like receptor signaling pathway and the NF-κB signaling pathway. BEO also reduced the severity of acne lesions, induced by intracutaneous injection of S. epidermidis in a rabbit ear acne model. The expression of inflammatory mediators and key signaling pathway components, including TLR2, AKT, P13K, NF-κB, TNF-α, IL-1β in rabbit ear, and TNF-α and IL-1 β in serum, were down-regulated (p < 0.05), indicating that BEO acts by inhibiting the pro-inflammatory TLR2/PI3K-AKT/NF-κB signaling pathway.Conclusion: The current results showed that BEO has clear potential for development into a natural and safe anti-inflammatory skin preparation, which is an effective alternative to conventional treatments containing antibiotics and synthetic anti-inflammatory agents.
PAC: Privacy preserving proxy re-encryption for access control in public cloud

ABSTRACT Proxy re-encryption is an essential prerequisite that facilitates a foreign entity (e.g., cloud server) to enforce the access of provisions of a document extended by one user to another user. While performing this task it is essential that the foreign entity does not learn any information about the actual document inside the encrypted envelop. In this paper, we present a scheme on Privacy-preserving Proxy Re-encryption for Access Control in Public Cloud, termed as PAC, that provides the proxy re-encryption of attribute-based encrypted data with receiver privacy. The proposed PAC scheme enables a proxy server to perform the re-encryption operation without learning anything about the data or the access policy. The PAC provides data confidentiality, and preserves receiver privacy. We show the PAC scheme adaptively secure against indistinguishability of ciphertext policy and chosen-plaintext attack (IND-CP-CPA) under the 2-Decisional Bilinear Diffie-Hellman Inversion assumption. The scheme is implemented on Google cloud instance and the experimental results show that the PAC scheme is storage and computation-efficient when compared to other related schemes.
Metabolic syndrome among Nigerians with type 2 diabetes mellitus: a comparative study of the diagnostic criteria.

BackgroundMetabolic syndrome is associated with increased cardiovascular death. The objectives of this study were to find the frequency of metabolic syndrome among Nigerians with type 2 diabetes and to compare the modified NCEP ATP III criteria and the IDF criteria MethodsThe study involved 134 participants. Sixty-seven were cases with type 2 diabetes while the rest were the controls without type 2 diabetes. Ethical approval was granted by the institution’s ethics review committee. Anthropometric, clinical and laboratory parameters were obtained using standard protocols. Data were analyzed with SPSS version 22. Means were compared with Student’s t test while proportions were compared with the Pearson’s chi square. Point biserial correlation was used to determine the association between the dichotomous variables and interval variables. Agreement between the criteria was tested with the Cohen’s kappa test.ResultsType 2 diabetes was associated with a higher prevalence of hypertension and truncal obesity. The frequency of metabolic syndrome was lower with the IDF criteria compared with the modified NCEP criteria (65.7% vs 71.6%). Although there was a strong agreement between the IDF and the modified NCEP criteria (κ=0.862; p<0.0001) yet, the IDF criteria missed 8.3% of diabetic individuals diagnosed with metabolic syndrome by the modified NCEP criteria. Cardiovascular risk is better predicted when the modified NCEP criteria were used to diagnose metabolic syndrome.ConclusionMetabolic syndrome is very common among Nigerians with type 2 diabetes and it is better diagnosed with the modified NCEP ATP III criteria.
Privacy-Preserving IP Verification

The rapid growth of the globalized integrated circuit (IC) supply chain has drawn the attention of numerous malicious actors that try to exploit it for profit. One of the most prominent targets of such parties is the third-party intellectual property (3PIP) vendors and their circuit designs. With the increasing number of transactions between vendors and system integrators, the threat of IP reuse and piracy has become a significant consideration for the IC industry. What is more, the correctness of 3PIP designs should be verified before integration, imposing another challenge for 3PIP vendors since they have to prove the functionality of their designs to system integrators while protecting the privacy of the circuit implementations. To eliminate this deadlock, we utilize the cryptographic technique of “zero-knowledge proofs” to enable 3PIP vendors to convince system integrators about various functional properties of a circuit (e.g., area, power, and frequency) without disclosing its netlist (i.e., in zero-knowledge). Our approach comprises a circuit compiler that transforms arbitrary netlists into a zero knowledge-friendly format and a library of modules that provide cryptographic guarantees for various properties of the netlist while hiding the actual gates. We evaluate our method using combinational and sequential circuits from the ISCAS and ITC benchmark suites.
Quantum Chemical Study of Molecular Recognition between Etravirine/Rilpivirine and the HIV-1 Reverse Transcriptase

Second generation non-nucleoside reverse transcriptase inhibitors (NNRTIs) etravirine and rilpivirine are essential components in the highly active antiretroviral therapy for the treatment of patients infected with human immunodeficiency virus type 1 (HIV-1). They are highly potent drugs against wild-type viruses and have exhibited excellent antiviral activities against some NNRTIs-resistant HIV-1 variants. In order to understand the underlying mechanism behind their robust resistance profile in comparison with the first generation NNRTIs nevirapine and efavirenz, it is necessary to quantitatively analyze their binding pockets in the wild-type HIV-1 reverse transcriptase (RT) and various HIV-1 RT mutants at the molecular level. Therefore, a high-level ab initio quantum chemical analysis was performed to decipher the molecular determinants for recognition of etravirine and rilpivirine by the wild-type RT and some RT mutants (K103N, K103N/Y181C, and K103N/L100I) of clinically important virus strains. Pair wise intermolecular interaction analysis determined the contribution of individual intermolecular interactions to the binding affinities between the second generation NNRTIs (etravirine or rilpivirine) and several variants of RTs, including the wild-type RT, and clinically relevant K103N, K103N/Y181C, and K103N/L100I mutant RTs. This quantitative analysis led to the identification of drug-protein interactions that persist despite mutations as well as to the evaluation of stabilization energy losses upon mutations. The results of this study enhanced our understanding of the molecular level mechanisms by which the second generation NNRTI drugs maintain their strong binding to mutant RTs. It is hoped that findings of this work would have a direct impact on designing new NNRTIs that are even more resilient to mutations in future.
Regulated Deficit Irrigation and Its Effects on Yield and Quality of Vitis vinifera L., Touriga Francesa in a Hot Climate Area (Douro Region, Portugal)

Under a climate change scenario, vineyards will experience serious challenges in the future. In an attempt to overcome such difficulties, this experiment offers a study on the effect of regulated deficit irrigation as a method for short-term adaptation to climate change in cv. Touriga Francesa, grafted into the rootstock 110R in the Douro region during a three-year period. Water stress on the plant and its effects on canopy, production, and quality of musts were analyzed. Rainfed vines (R0) were compared to three deficit irrigation regimes as a function of estimated crop evapotranspiration (ETc): R25 (25% ETc), R50 (50% ETc), and R75 (75% ETc). Water was applied on a weekly basis whenever predawn water potential showed moderate water stress until 15 days prior to harvest. The results suggest that rainfed plants under these circumstances suffered, in general, a negative impact on vine performance, while moderate water stress had more favorable effects on fruit composition, as well as in yield. Nonetheless, further studies should be conducted as irrigation did not show consistent effects on yield or berry composition.
National farm assurance scheme demonstrates welfare outcome improvements for sustainable intensification of dairy production

ABSTRACT Animal welfare is a key pillar of sustainability in livestock farming but can be challenging to deliver improvements when productivity is high. In October 2013, the Red Tractor UK national dairy assurance scheme introduced welfare outcome monitoring on its 11,500 farms, covering 95% of UK milk produced. Here we show that 98 farm assurance assessors achieved high levels of agreement with a gold standard and report data they collected for three years from 248,689 cows, typically 10 cows per farm, during 19,899 audits. Between 2013 and 2014, and 2015 and 2016, the estimated national prevalence fell significantly for lameness (from 10.0% to 7.9%), dirtiness (from 12.4% to 9.2%), ‘hairloss, lesions and swellings’ (from 9.3% to 6.5%), and fat cows (from 2.4% to 1.9%). This occurred at a time when milk yield per cow increased. We have demonstrated an effective implementation strategy suitable for uptake internationally to align with societal sustainability goals.

Entrepreneurial orientation, competitive advantage and strategic knowledge management capability in Malaysian family firms

Purpose The purpose of this study is to test the thesis that the family firm’s success hinges on effective strategic knowledge management (SKM) capability coupled with an entrepreneurial orientation (EO). Contingency theory holds that entrepreneurial success is contingent on strategic capabilities and resource orchestration theory explains how well family firms nurture capabilities to structure, bundle and leverage resources that define competitive advantage (CA). This study combines these two theoretical viewpoints to propose the effects of EO and SKM capability on CA to achieve successful performance in family firms. Design/methodology/approach This study uses a hybrid approach applying structural equation modelling (SEM) and deep-learning artificial intelligence (DL-AI) analysis to survey data on 268 Malaysian family firms. Findings SEM results confirm that CA mediates the relationship between innovativeness, proactiveness and risk-taking dimensions of EO and firm performance. Autonomy and competitive aggressiveness have no bearing, however. The relationships among innovativeness, proactiveness and risk-taking with CA and performance are positively moderated by SKM capability, becoming more potent at higher levels. Moreover, four additional DL-AI models reveal the necessity of specific EO dimensions and the interacting effects of EO–SKM capability to influence CA and to attain performance success subsequently. Originality/value This study theorizes and presents two new boundary conditions to a knowledge-based theory of the family firm and its firm performance. First, CA mediates the relationship between EO and performance; and second, SKM capability moderates the relationships between EO and CA and between EO and family firm performance. Methodologically, this study uses DL-AI to embrace non-linearity and prioritize predictor variables based on normalized importance to produce greater accuracy over regression analysis. Hence, DL-AI adds methodological novelty to the knowledge management and family firm literature.
Portfolio optimization with wealth-dependent risk constraints

Regulatory risk constraints as in the European Solvency II standard formula for insurance companies may lead to wealth-dependent constraints on the investment strategy. We develop two solution approaches for portfolio optimization problems in continuous time with wealth-dependent constraint sets. In the first approach, we reduce the optimization problem to an associate problem with constraints independent of wealth and a different utility function. The associate problem is then solved using known convex duality results. In the second approach, we use a change of control. We apply these results to Solvency II constraint sets and find that even for an investor with HARA utility who inherently reduces risk in times of distress, the constraints help to prevent the investor from taking too much risk in an optimistic market. Furthermore, we measure significant loss in utility and reduction in risk caused by the constraints, and we also evaluate the trade-off between these two effects.
A comfortable soundscape perspective in acoustic environmental planning and management: a case study based on local resident audio-visual perceptions

Soundscapes are an important factor related to audio-visual perception and human health; however, research on how local residents perceive the audio-visual environment remains insufficient. This study, therefore, was mainly conducted to examine the effects of sound sources, the sociodemographic factors of the local residents, visual aesthetic quality and quiet landscape experiences on rural soundscapes through on-site and in-home questionnaire surveys focusing on three components of a soundscape. The results indicated that although there were significant differences in the audio-visual perceptions among typical locations, road traffic sounds were the dominant sound category affecting acoustic comfort on site and in memory. The residents’ age affected the acoustic comfort of background sounds and sound marks in certain ways, while positive landscape experiences made sound marks predominantly perceived and the acoustic comfort of each sound category remarkably improved. This study also developed an agile practical soundscape resource optimization process through an audio-visual perceptual investigation.
