“ANA É UMA IDIOTA E FERNANDO ESTÁ CERTO”: CONSTRUINDO REFLEXÕES SOBRE O IMAGINÁRIO SOCIAL DE RESPONSÁVEIS ENVOLVENDO GÊNERO, CONSERVADORISMO E LAICIDADE.
Authors: Cavalcante da Silva Julia Dionísio , Nascimento Ramôa Hosana do
Published: June 2022

Este artigo é resultado de uma pesquisa já concluída, que teve como objetivo entender como responsáveis por estudantes compreendem o conservadorismo e a laicidade na educação, por meio de suas percepções sobre questões de gênero. Utilizando uma “ferramenta de imaginário social”, na qual duas personagens emitiam opiniões antagônicas a respeito de um menino vestindo saia, pedimos que as responsáveis comentassem suas considerações. A partir das 22 respostas obtidas, concluímos que mais do que posições polarizadas sobre o assunto, nossas participantes nos ofereceram um espectro de posicionamentos que escapavam da esperada dualidade conservadorismo/progressismo. Mostrando que as pessoas são capazes de combinar, em suas elaborações e argumentações sobre gênero, noções muitas vezes dissonantes acerca do respeito às diferenças e à pluralidade inerentes à nossa sociedade, bem como a respeito do papel da religião na questão.
The Effects of Different Exposure Factors on Leakage Radiation in an X-ray Room
Authors: Naji Abdullah Taher
Published: June 2022

This study evaluated leakage radiation doses inside an x-ray room at patient’s positioning levels. The effects of different exposure settings (X-ray tube voltage, radiation exposure intensity, dosimeter position, and distance from X-ray tube) on leakage radiation dose are estimated. Various x-ray tubes and models were used in this evaluation. The findings of this study revealed that, the increase of tube voltage (kVp), and tube current (mAs) led to a concomitant increase in the quantity of leakage radiation, whereas the increase in distance from X-ray tube and dosimeter position reduces the intensity of recorded leakage radiation according to inverse square low. In addition, the evaluation of leakage X-ray for investigated X-ray units illustrated that, leakage radiation doses at patient level around X-ray tubes were within the permissible occupational dose. Finally, the reduction of leakage radiation dose can be acquired by reducing the intensity of radiation (mAs) and increasing the distance between imaged object and x-ray source.

Published: June 2022

La deposición de nutrientes por vía atmosférica tiene graves impactos sobre la ecología de bosques y cuerpos de agua templados. Sin embargo, su importancia en cuerpos de agua neotropicales casi no ha sido estudiada. En este artículo se cuantifica la contribución de nitrógeno inorgánico disuelto (NID, [NO3--N + NH4+-N]) y fósforo inorgánico soluble (FIS, [PO4-3-P]) depositados en bulto sobre superficies húmedas por vía atmosférica hacia el lago Atitlán (Guatemala). Las cargas estimadas de NID y FIS consecuencia de la deposición atmosférica directa (depositada sobre la superficie del lago) fueron de 151.2 ton/año y 5.6 ton/año, respectivamente. Con estos resultados, se estima que el aporte de FIS por deposición atmosférica al lago Atitlán es comparable al de sus principales ríos tributarios, y de casi el doble para el ingreso de NID. Las estimaciones para el lago Atitlán son mayores que lo reportado para otros lagos. Nuestro estudio proporciona información básica para entender la eutrofización del lago Atitlán, enfatizado en la importancia de la deposición atmosférica como contribuyente al deterioro de este cuerpo de agua. Además, demuestra la necesidad de extender este tipo de estudio a otras cuencas neotropicales y la importancia de minimizar este impacto.

Authors: Heim René H.J. , Streit Sebastian , Koops Dirk , Kuska Matheus Thomas , Paulus Stefan
Published: June 2022

Weed scoring is crucial to test the efficacy of herbicides and other weed management methods but has proven to be labor intense and variable across scoring individuals and time. This article provides a comparison of new approaches of weed scoring based on digital tools to conventional visual scoring. The first method collected aerial imagery that was then scored manually on a computer screen. The second method is a machine learning approach, automatically detecting and counting weeds in aerial imagery. The reference method is a conventional visual scoring by human raters. Across all scoring methods, the results show similar patterns, but the total number of scored plants differs. In comparison to the digital approaches, in field scoring by human raters estimated a higher weed infestation. Possible reasons for this, as well as the advantages and disadvantages of each method are discussed to explore new modes of weed scoring. A clear benefit of digital scoring is the potential to automate the procedure and its objective, repeatable nature.

Published: June 2022

As we know from biophysics, infrared tympanic thermometers are easy to use and have a fast response time. They are widely used to measure human body temperature. Measurement accuracy and uncertainty are the most important performance indicators for these measuring instruments. This study evaluated the performance of two infrared tympanic thermometers, the Brown THT-3020 and the OMRON MC-510. The temperature of the temperature calibrator was changed to serve as the standard temperature of the "black body". The measurement errors for the two measuring instruments were reduced by the calibration equation. The predicted values meet the requirements of the ASTM standard. Sources of uncertainty include standard deviations of repetition at constant temperature or predicted values of the calibration equation, reference standard values, and resolution. Uncertainty analysis shows that the uncertainty of the calibration equation is the main source of combined uncertainty. The ambient temperature did not significantly affect the measured performance. The accuracy of infrared tympanic thermometers can be increased by the specified calibration equations.

Authors: Tyas Fitri Mutiaraning , Nuria Ludvi Azizi  , Nia Yuniarsih
Published: June 2022

Antioxidants for facial skin care would be better formulated in a topical form because the active substances will interact longer with facial skin. Indonesia is known for its wealth of natural ingredients that are useful as antioxidants. Research related to natural ingredients has been widely carried out and has good content for the skin. The good antioxidant content in herbal plants is in the form of secondary metabolites, namely flavonoids, alkaloids, phenolic compounds, carotenoids, tannins, steroids, and triterpenoids. This literature review aims to describe traditional Indonesian natural ingredients that have the potential to contain antioxidants that can be made into face mist and spray gel preparations. In conclusion, plants that can be formulated as face mist preparations are purple cabbage, yam tubers, and saffron flowers. Meanwhile, the herbs that can be used for spray gel preparations are strawberry fruit, buas-buas leaf, sweet orange peel, and purslane plant.
On a Solutonto the Statonary Problem of Two-Phase Filtration by the Monte Carlo Method
Authors: Tastanov M. , Utemissova A. , Maiyer F. , Ysmagul R.
Published: June 2022

This article is devoted to solving the problems of applying Monte Carlo algorithms to filtration problems. The "sphere walk" and "boundary walk" algorithms of Monte Carlo methods are used to solve the stationary problem of filtering two immiscible inhomogeneous incompressible liquids in a porous medium. Estimates constructed using the "sphere walk" and "boundary walk" algorithms of Monte Carlo methods will be mostly ε-biased. Unbiased estimates are in most cases unrealizable on a computer, since with a probability of 1 they do not go to the boundary of the region, and therefore are of little use. In practice, they are usually limited to only the first two points of evaluation.

Esta reflexión se desprende de una serie de investigaciones cualitativas, relacionadas con los profundos impactos culturales, estéticos y eróticos en la sociedad mexicana. La inserción de México al Tratado de Libre Comercio, junto con Estados Unidos y Canadá (1994) promovió nuevas ofertas eróticas, así como la construcción de imágenes y relatos de un país que se reinventaba y americanizaba vertiginosamente. Asimismo, se pretenden desnaturalizar las representaciones sociales y su carga ideológica, ahora que los intercambios económicos se han renegociado en un nuevo tratado comercial (2018). Y un gobierno que sintomáticamente se denomina Morena y que promete un nuevo relato histórico.

Significance of Air Transport to Tourism-Induced
Growth Hypothesis in E7 Economies
Authors: Onifade Stephen Taiwo , Gyamfi Bright Akwasi , Bekun Festus Victor , Altuntaş Mehmet
Published: June 2022

The study seeks to examine the significance of the tourism-induced growth hypothesis from the perspective of air transportation among seven emerging (E7) countries, including China, India, Brazil, Mexico, Russia, Indonesia, and Turkey. The combined impact of energy consumption and globalization was also factored into the analysis in order to draw cogent implications for environmental quality as energy demand in E7 economies continues to rise amidst growing urbanization in recent times. The study leverages on second-generational panel data estimators, namely cross-sectional autoregressive distributed lag, augmented Mean Group, and Dumitrescu-Hurlin Causality techniques. Having established a long-run equilibrium relationship among the outlined variables, the result validates the pertinent role of air transport in enhancing economic growth as a percent rise in airline passengers' arrivals significantly enhances growth in the E7 economies by 0.77%. In addition, the feedback causality between the variables also strengthens the pivotal roles of air transport in economic growth, thereby giving credence to the tourism-led growth hypothesis (TLGH) in the E7. However, there are detrimental environmental implications for the E7 when considering the causal nexus between economic growth and the dynamics of carbon-inducing energy consumption among the countries. Hence, investments in clean energy and transport infrastructures are recommended to ensure a sustainable environment where the tourism industry can flourish.
Celebrity-Induced Yoga Tourism
Authors: Balakrishnan Nair Bipithalal , Solanki Sandip
Published: June 2022

The present-day stress, societal changes, and hectic life make the quest for mental and physical well-being. The market for yoga tourism has been growing ever before. Ashrams and Gurus are vital aspects of Yoga tourism. These religious gurus are functional celebrities with millions of followers and franchises worldwide. Gurus are inextricably linked to the global popularisation of Yoga, and they have the potential to be more convincing than government initiatives since they travel to and through more nations and establish personal contact zones between multinational groups. To this end, this study examines the significance of religious gurus as celebrities in promoting Yoga tourism. This research utilized a qualitative interpretive approach by the application of Netnography. The findings emphasize the substantial role of religious gurus in tourists’ motivation, behavioral intentions, destination attachment, and ashram selection. The study also connects the search for authenticity in the well-being tour with the pleasant tourism experience that Yoga ashrams offer.

Regarding the necessity of developing transportation infrastructures and its increasing importance in urban issues, nowadays in different cities, bicycles are considered the main and sustainable vehicle along with walking and drawing more attention day by day. The case considers highly paramount since preservation of the environment, natural resources, and energy is one of the significant pillars of sustainable development, and urban transportation intensively influences it. Thus, Bicycle Sharing System (BSS) is recognized as an innovative urban transportation option that meets the citizens’ demand for commuting during the day. The BSS can highly affect the level of citizens’ health, and it can be counted as one of the leading health programs whether it’s added to the public transportation system, it can help the culture to be created to use bicycles instead of cars in most of the internal trips, and also it can be so influential in decreasing the air pollution and in the following its harmful effects on health issues. The mathematical model of rebalancing multi-zone BSS with mobile stations and applying maintenance constraints in a static status is considered in this research. The objective function of this research is a single-objective one, which is modeled with the aims of reducing the costs of traveled distances by the tracks within and outside the zones, reducing the costs of intact and defective bicycles transportation within and outside the zones, and eventually, reducing the costs of surplus bicycles depot at the stations. This issue is a multi-product one that includes different types of bicycles and balancing tracks. Computational results confirm the model’s efficiency. Also, sensitivity analysis has been done to prove that the model is affected by both parameters of storage costs of surplus bicycles and transportation costs within and outside the zones.
How Do Spitzer IRAC Fluxes Compare to HST CALSPEC?
Authors: Bohlin Ralph C. , Krick Jessica E. , Gordon Karl D. , Hubeny Ivan
Published: June 2022

An accurate tabulation of stellar brightness in physical units is essential for a multitude of scientific endeavors. The HST/CALSPEC database of flux standards contains many stars with spectral coverage in the 0.115–1 μm range, with some extensions to longer wavelengths of 1.7 or 2.5 μm. Modeled flux distributions to 32 μm for calibration of JWST complement the shorter-wavelength HST measurements. Understanding the differences between IRAC observations and CALSPEC models is important for science that uses IR fluxes from multiple instruments, including JWST. The absolute flux of Spitzer IRAC photometry at 3.6–8 μm agrees with CALSPEC synthetic photometry to 1% for the three prime HST standards: G191B2B, GD153, and GD71. For a set of 17–22 A-star standards, the average IRAC difference rises from agreement at 3.6 μm to 3.4% ± 0.1% brighter than CALSPEC at 8 μm. For a smaller set of G-type stars, the average of the IRAC photometry falls below CALSPEC by as much as 3.7% ± 0.3% for IRAC1, while one G-type star, P330E, is consistent with the A-star ensemble of IRAC/CALSPEC ratios.
The Criterion for Chaos in Three-planet Systems
Authors: Rath Jeremy , Hadden Sam , Lithwick Yoram
Published: June 2022

We establish the criterion for chaos in three-planet systems, for systems similar to those discovered by the Kepler spacecraft. Our main results are as follows: (i) The simplest criterion, which is based on overlapping mean motion resonances (MMRs), only agrees with numerical simulations at a very crude level. (ii) Much greater accuracy is attained by considering neighboring MMRs that do not overlap. We work out the widths of the chaotic zones around each of the neighbors, and also provide simple approximate expressions for the widths. (iii) Even greater accuracy is provided by the overlap of three-body resonances (3BRs), which accounts for the fine-grained structure seen in maps from N-body simulations, and also predicts Lyapunov times. From previous studies, it is unclear whether interplanetary chaos should be attributed to the overlap of MMRs or of 3BRs. We show that the two apparently contradictory viewpoints are in fact consistent: both predict the same criterion for chaos. (iv) We compare the predicted criterion with high-resolution maps of chaos from N-body simulations, and show that they agree at a high level of detail.

We present a measurement of the relativistic corrections to the thermal Sunyaev–Zel’dovich (SZ) effect spectrum, the rSZ effect, toward the massive galaxy cluster RX J1347.5-1145 by combining submillimeter images from Herschel-SPIRE with millimeter wavelength Bolocam maps. Our analysis simultaneously models the SZ effect signal, the population of cosmic infrared background galaxies, and the galactic cirrus dust emission in a manner that fully accounts for their spatial and frequency-dependent correlations. Gravitational lensing of background galaxies by RX J1347.5-1145 is included in our methodology based on a mass model derived from the Hubble Space Telescope observations. Utilizing a set of realistic mock observations, we employ a forward modeling approach that accounts for the non-Gaussian covariances between the observed astrophysical components to determine the posterior distribution of SZ effect brightness values consistent with the observed data. We determine a maximum a posteriori (MAP) value of the average Comptonization parameter of the intracluster medium (ICM) within R
2500 to be 〈y〉2500 = 1.56 × 10−4, with corresponding 68% credible interval [1.42, 1.63] × 10−4, and a MAP ICM electron temperature of 〈T

The Influence of Surface Binding Energy on Sputtering in Models of the Sodium Exosphere of Mercury
Authors: Killen Rosemary M. , Morrissey Liam S. , Burger Matthew H. , Vervack Ronald J. , Tucker Orenthal J. , Savin Daniel W.
Published: June 2022

We have simulated the sodium (Na) exosphere of Mercury to show how the exosphere is affected by the assumed surface binding energy (SBE) of Na in the sputtered component. We constrained ion precipitation onto the surface using distributions for the cusp regions that are consistent with measurements by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging Fast Imaging Plasma Spectrometer instrument. We have simulated sputtering with SBEs of 0.27, 2.6, 4.4, and 7.9 eV, with the lowest value commonly used in exosphere models and the highest from recent molecular dynamics calculations for the Na-bearing feldspar end-member, albite. A gradual change in the exosphere is seen as the yield decreases and the ejecta energy increases with increasing SBE. We describe the corresponding exosphere source functions for ion sputtering (IS), as well as for the previously studied processes of micrometeoroid impact vaporization and photon-stimulated desorption (PSD), along with their release energy distributions and spatial distributions. We have summed the contributions of the various source processes to explain how and when the different sources can be distinguished by observations. The modeled exosphere scale heights range from 72 km for PSD to over 1000 km for IS using a SBE of 7.9 eV. We find that the processes responsible for generating Mercury's Na exosphere are separable by measuring line-of-sight column densities tangent to the planet at various altitudes and positions around the planet. Our initial results are consistent with the Na being sputtered from a high-SBE material such as feldspar, which has been predicted to be abundant on the Mercury's surface.
Semitendinosus and Gracilis Autograft for Neglected Patellar Tendon Rupture: A Surgical Reconstruction
Authors: Adisthanaya Surya , Astawa Putu , Aryana I Gusti Ngurah Wien , Febyan
Published: June 2022

BACKGROUND: Neglected patellar tendon rupture is an extremely rare case among orthopedic injuries that severely compromises the function of the extensor mechanism of the knee. Therefore, a prompt and accurate diagnosis of a ruptured patellar tendon are a key to efficacious management, because a treatment delay is often associated with unsatisfactory functional outcomes.

CASE PRESENTATION: We report the case of an adult male patient with traumatic patellar tendon rupture after 9 months of a motorcycle accident. The patient underwent reconstruction surgery using semitendinosus and gracilis tendon augmentation. This procedure restores the anatomical position of the patella and prevents extensor lag. At a 3-month follow-up, a full recovery of the structure and function of the extensor mechanism was perceived. The patient could return to normal daily activities following rehabilitation protocol.

CONCLUSION: Semitendinosus and gracilis tendon autograft is the technique of choice to be applied in the surgical reconstruction of neglected patellar tendon rupture.

Published: June 2022

Objective

Heterogeneity exists among patients with myositis who have antinuclear matrix protein 2 (anti-NXP2) antibodies, although they usually present with severe muscle weakness. This study aimed to investigate the differences in phenotypes and prognoses among adult patients with myositis who have anti-NXP2 antibodies.

Methods

Adult patients with myositis who have anti-NXP2 antibodies were enrolled from January 2010 to December 2019. Their clinical features and laboratory data were recorded retrospectively. We followed up on their survival status until June 30, 2020. A hierarchical cluster analysis, Kaplan-Meier curves, and classification and regression trees were used to analyze the data.

Results

A total of 70 adult patients with myositis who have anti-NXP2 antibodies were enrolled. All patients experienced muscle weakness. A total of 11 patients did not present with rashes during disease progression, and 43 patients developed dysphagia. In total, 21 patients had interstitial lung disease (ILD), whereas no patients had rapidly progressive ILD. Hierarchical cluster analysis identified 2 clusters. Patients in cluster 1 were younger at disease onset, had a higher incidence of subcutaneous calcification, and had a lower incidence of V sign and shawl sign. Patients in cluster 2 had a higher frequency of ILD, accompanied by lower levels of lymphocytes and higher levels of serum ferritin. Moreover, patients in cluster 2 had worse prognoses.

Conclusion

Patients with myositis who have anti-NXP2 antibodies may present with different phenotypes that are characterized by unique features and prognoses.

Authors: Hwang Ji Sup , Lee Sanghoon , Shin Jung Wook , Kim Ki Woong , Gong Hyun Sik
Published: June 2022

Objective

Index-to-ring finger ratio (IRFR) has been reported to be associated with joint osteoarthritis (OA). We aimed to evaluate the association between IRFR and trapeziometacarpal joint (TMCJ) OA in an elderly Korean population.

Methods

A population-based sample included 604 participants with a mean age of 74.8 years. IRFR was radiographically measured by the ratio of the length of the right second to fourth phalangeal bones (“phalangeal IRFR”) and metacarpal bones (“metacarpal IRFR”), and was visually classified as either type 1 (index finger longer than or equal to ring finger) or type 2 (index finger shorter than ring finger). Odds ratios (ORs) for the presence of OA (Kellgren-Lawrence [KL] grade > 1) and for severe OA (KL grade > 2) were analyzed using logistic regression.

Results

The phalangeal IRFR averaged 91.3%, the metacarpal IRFR 116.7%, and 304 out of 604 participants (50.3%) had type 2 IRFR. We found TMCJ OA in 112 participants (18.5%), and severe TMCJ OA in 33 participants (5.5%). Presence of TMCJ OA was significantly associated with age (OR 1.04; 95% CI 1.01-1.06) and metacarpal IRFR (OR 0.94; 95% CI 0.88-0.99), and severe TMCJ OA with age (OR 1.08; 95% CI 1.03-1.12) and type 2 IRFR (OR 3.07; 95% CI 1.13-8.33).

Conclusion

Radiographic IRFR, specifically metacarpal IRFR, was associated with the presence of TMCJ OA, and visual IRFR with severe TMCJ OA in both elderly Korean men and women. The results of this study suggest that IRFR might serve as an easily measurable biomarker to identify patients vulnerable to TMCJ OA.
Impact, influence, importance : comment « mesurer » la contribution des femmes à l’histoire de la philosophie ?
Authors: Wilkin Rebecca
Published: June 2022

Cet article identifie l’une des causes de l’exclusion des femmes de l’histoire de la philosophie : l’influence causale qui en est le principe narratif. L’influence est souvent décrite comme l’effet direct du texte philosophique, mais en fait c’est le lecteur qui consent à se laisser influencer. Chaque lecteur aborde le texte qu’il lit avec des préjugés, et ces préjugés peuvent contribuer à déterminer l’influence qu’il choisit de lui accorder. Je me sers des ouvrages de Gabrielle Suchon et de Louise Dupin afin de montrer combien le critère de l’influence renforce la dépossession systématique des femmes en tant que philosophes.

Le plan de soin anticipé permet de planifier à l’avance les objectifs de soins du patient en favorisant la communication interprofessionnelle. Un projet de recherche qualitative a été initié auprès des infirmières et des médecins en charge de patients qui pourraient bénéficier de soins palliatifs. L’utilisation du plan de soin anticipé a été proposée à la suite d’un sondage permettant d’évaluer les besoins en communication et de mesurer la facilité du dialogue autour des discussions d’attitude pour les patients atteints d’une maladie chronique évolutive.
Les importations et les exportations dans les anciens P.T.O.M. britanniques entre 1995 et 2018

Les données de l' Observatory of Economic Complexity (O.E.C.) recensent l’intégralité des importations et des exportations entre 1995 et 2018. Celles concernant les P.T.O.M. britanniques en ont été extraites. Ce texte analyse leurs flux avant le brexit , et tente d' ’en comprendre les répercussions. Tous ces territoires sont de type insulaire. De fait, les partenaires commerciaux associés aux flux ont une propension à changer d’une année à l’autre, ce qui rend l’analyse des partenariats entre les territoires très complexe, car l’outiltraditionnel du top 5 est insuffisant du fait de son instabilité dans le temps. Ainsi, cette contribution essaye de lever cette obstruction en utilisant la méthode statistique de concordance des rangs à deux échelles territoriales. Fort de cet outil, une lecture plus précise peut être réalisée par des indicateurs traditionnels, ce qui permettra d’entrevoir l’impact global du brexit sur l’ensemble des P.T.O.M. britanniques.
Investigating the validity of the short form Burnout Assessment Tool: A job demands-resources approach
Authors: De Beer Leon T. , Schaufeli Wilmar B. , Bakker Arnold B.
Published: June 2022

The purpose of this study was to investigate the psychometric properties of the short form Burnout Assessment Tool (BAT-12). As a result of the pandemic, job stress has been compounded and the use of conceptually grounded and accurate measures is needed to identify burnout risks within specific organisations and the overall workforce. The study sample comprised 660 employees from various occupational settings who filled out an online survey. Latent variable methods with ordinal categorical data were implemented to model the data and to test the hypotheses for the study. Results showed that the proposed second-order factor model of the BAT-12 showed a good fit to the data and was invariant across gender and ethnicity. In addition, burnout – as operationalised with the BAT-12 – played the hypothesised mediating role in the Job Demands-Resources model. The BAT-12 also showed convergent validity with the Maslach Burnout Inventory. The authors conclude that BAT-12 is a robust instrument with adequate psychometric properties to measure burnout risk and present a freely available online application for employees to estimate their risk of burnout.
Youth ministry as a public practical theology: A South African evangelical perspective
Authors: Aziz Garth
Published: June 2022

Youth ministry as a sub-discipline of practical theology has traditionally always had an ecclesial focus. The focus was often based on the practices of proselytisation and discipleship, a sort of ‘reach and teach’ model whereby Christian believers would do the ‘reaching and teaching’ of the ‘lost’ youth. This is most true in an evangelical context and is further undergirded by a Western concept of personal salvation nearly devoid of any communal responsibilities and context. The traditional model, therefore, in evangelical churches was reaching the ‘lost’ with the Gospel of Jesus Christ, with the aim of personal salvation for the individual who would eventually become a member of the faith community through a discipleship programme. Thus, the beginning and end of the entire process were the focus on personal salvation devoid of any contextual consideration. Youth ministry as practical theology must move into the area of public theology to engage the practices inherited from the western model by engaging with the public (youths) as public theologians (those who influence the theologies of the youth), and the public faiths and spiritualities (the expression of the youth’s theologies) to be relevant to the majority and developing world.Contribution: In this study, the author suggests that this ‘reach and teach’ paradigm with an ecclesial focus in the context of the majority and developing world is no longer suitable to meet the needs of youth. In addition, the author recommends a more appropriate framework with youth ministry as public practical theology for consideration.

In vitro evaluation of antimicrobial and antioxidant activities of honeybee venom and propolis collected from various regions in Egypt
Authors: Elswaby Shimaa , Sadik Mahmoud , Azouz Alaa , Emam Nadia , Ali Mohamed
Published: June 2022

Background and objective

Honeybee products are commonly used as food and medicine. Recently, pharmacological properties of bee venom and propolis have been reported. However, the geographic origin of bee venom and propolis influences their chemical composition and biological activities. The antimicrobial and antioxidant properties of bee venom and propolis collected from different regions in Egypt were evaluated.

Materials and methods

Bee venom and propolis were collected from the regions of Kafr-Elsheikh, Fayoum, and Giza in Egypt. The antimicrobial and antioxidant effects of bee venom and propolis extracts obtained with various solvents were evaluated using the well-diffusion method and the 1,1-diphenyl-2-picrilidrazil free radical scavenging assay, respectively.

Results and conclusion

The antimicrobial activities of bee venom extracts were greater than those of propolis extracts, and ethanol extracts were more efficient than chloroform and water extracts. Extracts obtained from the Kafr-Elsheikh region were the most active, whereas those from the Giza region were less effective. Gram-positive bacteria were more sensitive than gram-negative bacteria and fungi. Propolis extracts were more effective antioxidants than bee venom extracts. The activities of extracts from the Kafr-Elsheikh or the Fayoum regions were comparable and greater than those of the corresponding extracts from the Giza region. Ethanolic extraction provided the greatest antioxidant potential. The biological activity of Egyptian bee venom or propolis varies significantly depending on the extraction solvent and geographical area of collection. These results provide insights into the antimicrobial and antioxidant properties of Egyptian bee venom and propolis and constitute a basis for further phytochemical and pharmacological research.
Quality by design approach to the development of self-microemulsifying systems for oral delivery of teriflunomide
Authors: Patel Alpesh D. , Shah Sayali , Patel Mukesh S. , Vyas Govind
Published: June 2022

Objective

The present study was aimed at the development of a self-microemulsifying drug delivery system (SMEDDS) for the low water-soluble drug using quality by design (QbD) to enhance the bioavailability of drugs.

Experimental work

The components of the SMEDDS were preliminarily screened using the pseudoternary phase diagram as a solubility study. The patient-centric, quality target product profile, and critical quality attributes were earmarked. Preformulation studies were performed along with an initial risk assessment that facilitated the selection of lipids (i.e. Sefsol 218), surfactants (i.e. Acrysol EL-135), and cosurfactants (i.e. PEG 400) as Critical Material Attributes for the formulation of SMEDDS. Extreme vertices mixture design, given its utility and the pertinence to the design issue in hand, was chosen for the study. The various responses selected for this design were drug release at 20 min (%), transmittance (%), emulsification time (s), and globule size (nm). Eleven distinct formulations were prepared and measured to check the model fit. The optimization and model validation were finished by directing experimental runs.

Results and discussion

Sefsol 218 (oil), Acrysol EL-135 (surfactant), and PEG 400 (cosurfactant) showed the highest solubility. The fourier transform infrared spectroscopy (FTIR) study suggested that there may be no significant difference in the characteristic’s peak at a wavenumber of the drug in the presence of excipients. The studies have shown that the application of extreme vertices mixture design and the development of formulation in QbD resulted in a powerful and viable technique for improving the bioavailability of the drug. This was confirmed by the characteristics’ studies of the optimized batch like in vitro drug release in 20 min (73.44%), drug content (99.3%), emulsification time (25 s), transmittance (99.5%), droplet size (16.64 nm), polydispersibility index 0.170, and zeta potential −9.74 mV. A great agreement was observed among the predicted and experimental values for the average globule size and percentage of the drug released in 20 min. Furthermore, the optimal SMEDDS formulation exhibited fundamentally higher, extreme-plasma concentration, and area under the curve values a twofold higher value (P<0.05) than the teriflunomide suspension.

Conclusion

In summary, the present studies report successful QbD-oriented development of a novel oral teriflunomide-loaded SMEDDS formulation to noticeably improve the bioavailability of low water-soluble drugs.
