A Split Face Comparative Study to Evaluate the Efficacy of 40% Pyruvic Acid vs. Microdermabrasion with 40% Pyruvic Acid on Biomechanical Skin Paramet…
2022
The synergy of cosmetic acids, with their keratolytic and antibacterial properties, with the mechanical exfoliation of the epidermis brings faster and better treatment results. The aim of the study was to compare the effects of using only pyruvic acid and the synergy of microdermabrasion and chemical exfoliation. In total, 14 women diagnosed with acne took part in the study. Two areas were marked on the participants’ faces: the right side (microdermabrasion treatment and a preparation containing pyruvic acid 40%) and the left side (preparation containing pyruvic acid 40%) without mechanical exfoliation. A series of four treatments was performed at 2-week intervals. Skin parameters such as s…

Exploring the cellular uptake of hectorite clay mineral and its drug carrier capabilities.
2022
In the last years, the use of clay minerals for pharmaceutical purposes has increased due to their interesting properties. Hectorite (Ht) is a clay belonging to the smectite group which has attracted attention for applications in biology, tissue engineering and as drug carrier and delivery system. However, the mechanisms involved in Ht cellular uptake and transport into cells, are still unclear. Herein, we used a labeled Ht (Ht/1Cl) to study both the cellular uptake, by confocal laser scanning microscopy, and internalization pathways involved in the cellular uptake, by various endocytosis-inhibiting studies and fluorescence microscopy. These studies highlighted that Ht can penetrate the cel…
Improved Performance in Quadrotor Trajectory Tracking Using MIMO PIλ-D Control
2022
This paper aims to develop a fractional control approach for quadrotor trajectory tracking. A fractional-order integrator (PIλ) with a feedback derivative scheme is designed to control each state of the MIMO system. The designed feedback controller stabilizes the initially unstable decoupled states and widens the stability, while PIλ provides precise trajectory tracking capabilities. After a successful simulation study, the new PIλ-D controller is implemented in the hardware environment. The various performance and load disturbance analyses reveal the effectiveness of the proposed scheme compared with the classical PD/PID controllers. The real-time study also shows that this scheme is a sim…

Relationship between inbreeding and milk production traits in two Italian dairy sheep breeds.
2022
The effects of inbreeding in livestock species breeds have been well documented and they have a negative impact on profitability. The objective of this study was to evaluate the levels of inbreeding in Sarda (SAR, n = 785) and Valle del Belice (VdB, n = 473) dairy sheep breeds and their impact on milk production traits. Two inbreeding coefficients (F) were estimated: using pedigree (FPED), or runs of homozygosity (ROH; FROH) at different minimum ROH lengths and different ROH classes. After the quality control, 38,779 single nucleotide polymorphisms remained for further analyses. A mixed-linear model was used to evaluate the impact of inbreeding coefficients on production traits within each …
Isovector Axial Form Factor of the Nucleon from Lattice QCD
2022
The isovector axial form factor of the nucleon plays a key role in interpreting data from long-baseline neutrino oscillation experiments. We present a lattice QCD calculation of this form factor, introducing a new method to directly extract its z-expansion from lattice correlators. Our final parameterization of the form factor, which extends up to spacelike virtualities of 0.7 GeV^2 with fully quantified uncertainties, agrees with previous lattice calculations but is significantly less steep than neutrino-deuterium scattering data suggests.
‘I do not trust any of them anymore’: Institutional distrust and corrective practices in pro-asylum activism in Finland
2022
Although there is extensive research on how institutional trust and distrust play out in the forms political participation takes, the existing research lacks thorough analysis on what trust and distrust actually consist of, that is, how individuals evaluate institutions as trustworthy or not and what consequences this evaluation has for individuals and their relation to the state more broadly. Drawing on qualitative research on Finnish citizens who engage in pro-asylum activism, we examine how institutional distrusting evolves as a reflexive process. By analysing citizens’ trust judgements on institutional practices and actions that follow, we argue that distrust in institutions enhances a…

Dietary Fats and Cardio-Metabolic Outcomes in a Cohort of Italian Adults
2022
Background: Dietary fats, and especially saturated fatty acid (SFA), have been blamed for being the culprit in the dramatic increase in obesity and its associated diseases. However multiple systematic reviews and recent meta-analyses do not support the association between SFA and cardiovascular diseases. Thus, the objective of this study was to test whether specific types and subtypes of dietary fats are associated with metabolic outcomes in a cohort of Italian adults. Methods: Nutritional and demographic data of 1936 adults living in the south of Italy were examined. Food frequency questionnaires (FFQs) were administered to assess the intake of total dietary fat and each specific class of …
Molecular Identification and Biochemical Characterization of Novel Marine Yeast Strains with Potential Application in Industrial Biotechnology
2022
Cell-based agriculture is an emerging and attractive alternative to produce various food ingredients. In this study, five strains of marine yeast were isolated, molecularly identified and biochemically characterized. Molecular identification was realized by sequencing the DNA ITS1 and D1/D2 region, and sequences were registered in GenBank as Yarrowia lipolytica YlTun15, Rhodotorula mucilaginosa RmTun15, Candida tenuis CtTun15, Debaryomyces hansenii DhTun2015 and Trichosporon asahii TaTun15. Yeasts showed protein content varying from 26% (YlTun15) to 40% (CtTun15 and DhTun2015), and essential amino acids ranging from 38.1 to 64.4% of the total AAs (CtTun15-YlTun15, respectively). Lipid conte…
Is HLA type a possible cancer risk modifier in Lynch syndrome?
2022
Lynch syndrome (LS) is the most common inherited cancer syndrome. It is inherited via a monoallelic germline variant in one of the DNA mismatch repair (MMR) genes. LS carriers have a broad 30-80% risk of developing various malignancies, and more precise, individual risk estimations would be of high clinical value, allowing tailored cancer prevention and surveillance. Due to MMR deficiency, LS cancers are characterized by the accumulation of frameshift mutations leading to highly immunogenic frameshift peptides (FSPs). Thus, immune surveillance is proposed to inhibit the outgrowth of MMR-deficient cell clones. Recent studies have shown that immunoediting during the evolution of MMR-deficient…

Non-Unitarity of the lepton mixing matrix at the European spallation source
2022
If neutrinos get mass through the exchange of lepton mediators, as in seesaw schemes, the neutrino appearance probabilities in oscillation experiments are modified due to effective nonunitarity of the lepton mixing matrix. This also leads to new CP phases and an ambiguity in underpinning the ''conventional'' phase of the three-neutrino paradigm. We study the CP sensitivities of various setups based at the European spallation source neutrino super-beam (ESSnuSB) experiment in the presence of nonunitarity. We also examine its potential in constraining the associated new physics parameters. Moreover, we show how the combination of DUNE and ESSnuSB can help further improve the sensitivities on …
Polycrystalline MoO3 films fabricated by pulsed laser deposition for infrared polarization manipulation
2022
We performed infrared optical characterization of polycrystalline MoO3 films deposited by pulsed laser deposition on fused silica substrates. Several samples have been fabricated using different parameters such as temperature and oxygen pressure. Our analysis shows that under appropriate fabrication conditions it is possible to obtain a dominant α-phase film, with a well-defined, normal to surface (z-axis) orientation. These results are confirmed by reflection spectra performed at 45° incidence angle revealing a strong modulation of the sharp z-phonon Reststrahlen band as a function of the incident field linear polarization.

The work focused on methods of performing accelerated aging tests in order to simulate different effects of environmental decay involving stone used on a historical site. The rock samples were examined before and after three treatment types: cyclic salt spray chamber, cycles of freezing–thawing and cycles of thermal shock. After each artificial aging cycle, changes in appearance were noted and chemical and phy…
Effect of Bariatric Surgery on Intima Media Thickness: A Systematic Review and Meta-Analysis
2022
Background: Obesity, and in particular extreme obesity, as a global health problem is an important risk factor for many diseases, including atherosclerotic cardiovascular disease (ACVD). Bariatric surgery might stop or slow atherogenesis by decreasing excessive weight in the early stages of atherogenesis, by suppressing low-grade systemic inflammation as well as by inhibiting oxidative stress and endothelial dysfunction. The aim of this meta-analysis was to provide an answer to whether bariatric surgery has a significant effect on intima-media thickness (IMT) which is a surrogate marker of early atherosclerosis and has a good correlation with atherosclerotic coronary heart disease. Methods:…

The analysis of the diet composition of the barn owl Tyto alba (Scopoli, 1769) from the region of Brzeg, Opolskie Voivodeship (Poland)
2022
Research on the diet composition of the barn owl Tyto alba was conducted near the town of Przecza in the area of Lewin Brzeski (Opolskie Voivodeship. On the basis of 1158 bone elements, 14 species of small mammals were found, including 4 insectivorous species (Sorex araneus, Sorex minutus, Neomys fodiens, Cocidura suaveolens), 5 vole species (Microtus arvalis, Microtus agrestis, Arvicola terrestris, Myodes glareolus, Microtus oeconomus) and 5 mouse species (Mus musculus, Apodemus agrarius, Apodemus flavicolis, Apodemus sylvaticus, Micromys minutus). The diet was dominated by 3 species: Microtus arvalis, Sorex araneus and the Apodemus agrarius. The conducted research clearly shows that the T…
Designing Trickle Irrigation Systems in Sloping Fields without Pressure-Compensating Emitters: Application of the IRRILAB Software
2022
When designing trickle irrigation systems in sloped fields, the use of pressure-compensating (PC) emitters is generally preferred to ensure the emitter distribution uniformity regardless of the land topography and the variable operating pressures. However, the cost of PC emitters is generally higher than non-pressure-compensating (NPC) ones; moreover, the compensating membrane installed inside the emitters can lose elasticity due to the exposition to solar radiation, water quality, and chemical applications. Recently, the irrigation laboratory (IRRILAB) version 1.0 software application was developed to design microirrigation systems for rectangular and planar sectors when using NPC emitters…
Validation of the Brief Perceived Positive Lockdown Impact Scale PPLIS-4
2022
Background: Although research showed that positive aspects of the lockdown were perceived during the pandemic, there are no tools to test the positive impact of mandatory social isolation on life. The present study aims to validate a newly developed, brief, four-item perceived positive lockdown impact scale (PPLIS-4). Methods: A cross-sectional online survey study was formed among 4370 adults in three samples: Sample 1 consisted of university students from Poland and Ukraine, Sample 2 consisted of Polish university students under 26 (emerging adults), and Sample 3 consisted of Polish and Ukrainian adults above 25 (non-emerging adults). The standardized questionnaire was used for criterion v…

In total, 20 studies meeting the eligibility criteria were reviewed after performing a search of the Scopus, Web of Science, and PubMed databases. The results suggested that religious and spiritual beliefs, thoughts, and practices (e.g., spiritual coping activities) might have both beneficial and deleterious effects on the way adolescents deal with their medical condition, on their psychosocial adjustment, on their mental and physic…
Les aspirations professionnelles des élèves sous le prisme des valeurs et compétences « vertes »
2022
Introduction Les enjeux environnementaux sont une des lignes de fracture importante entre les valeurs des générations, les jeunes devant faire face à l’héritage des générations précédentes (Peugny et Van de Velde, 2013). L’école semble y jouer un rôle de plus en plus majeur en multipliant les terrains d’apprentissage de ces problématiques alliant connaissances théoriques et éco-gestes (Glomeron et al., 2017). Ils se déclinent néanmoins de manière très variable selon les pays et leurs politiqu...
Variation in the stable isotope trophic position of the bluefish Pomatomus saltatrix (Linnaeus, 1766) from two Mediterranean sites: insights from a g…
2022
A direct consequence of sea warming is the shift in the distribution range of thermo-tolerant species that have the potential to determine novel inter-specific interactions, ultimately altering food web structures and ecosystem processes. In this study, we investigated the trophic position of the bluefish Pomatomus saltatrix (Linnaeus, 1766), a pelagic predator that has recently expanded its distribution in the Mediterranean basin and for which scant information is available on its functional role in recently-colonised areas. Nitrogen and carbon stable isotopes were determined in muscle tissues of bluefish specimens collected in south-east Italy in the Gulf of Taranto (NW Ionian Sea) and in…

Catechol-Functionalized Carbon Nanotubes as Support for Pd Nanoparticles
2022
Carbon nanotubes have been covalently functionalized with catechol moieties through the formation of the corresponding aryl radicals obtained by reacting 4-aminocatechol with isoamyl nitrite. The functionalized multiwalled carbon nanotubes have been in turn used to immobilize Pd(II) ions on its surface forming catechol-Pd complexes, which were reduced to Pd nanoparticles (NPs). The so-obtained hybrid material has been characterized by means of thermogravimetric analysis coupled with differential scanning calorimetry (TGA-DSC), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). This latter technique allowed to estimate the nanoparticle size (5.7 +/- 2.8 nm) wh…
Evaluation of Surgical Outcomes of Abdominal Radical Hysterectomy and Total Laparoscopic Radical Hysterectomy for Cervical Cancer: A Retrospective An…
2022
Although a surgical approach is one of the key treatments for stages IA1-IIA2, results of the Laparoscopic Approach to Cervical Cancer (LACC) published in 2018 radically changed the field, since minimally invasive surgery was associated with a four-fold higher rate of recurrence and a six-fold higher rate of all-cause death compared to an open approach. We aimed to evaluate surgical outcomes of abdominal radical hysterectomy (ARH) and total laparoscopic radical hysterectomy (TLRH) for cervical cancer, including data collected before the LACC trial. In our retrospective analysis, operative time was significantly longer in TLRH compared to ARH (p < 0.0001), although this disadvantage could…
Tempo-controlled resistance training of the hip abductors and ankle dorsiflexors with light loads does not improve postural sway in older adults.
2022
The force steadiness capabilities of the hip abductors and ankle dorsiflexors can explain a significant amount of the variance in postural sway during four types of standing balance tests. Control over balance, as well as force steadiness, generally worsens with aging, although the latter can be improved with unique training interventions. The purpose of our study was to assess how tempo-controlled, light-load resistance training of the hip abductors and ankle dorsiflexors influences performance in clinical movement tests, postural sway, muscle strength, and force steadiness in older adults. Participants (n = 28, 70 +/- 7 years, 8 men) completed nine training sessions for either the hip abd…
Regards sur les pratiques épistolaires dans le monde monastique : Abbon de Fleury, Constantin de Micy et quelques exemples ligériens (980-1030)
2022
International audience; Dès l’Antiquité tardive, le monachisme oriental témoigne de l’importance des correspondances monastiques tant dans les échanges entre communautés que dans les relations entre les frères et le monde extérieur. L’intérêt de ces échanges est autant dans l’abondance du corpus que dans sa composition, sa diversité et l’étendue des thématiques qui y sont abordées, y compris les plus formelles. En Occident, il faut attendre les temps carolingiens pour observer un net retour de ces pratiques épistolaires en lien avec l’expansion de l’empire et surtout avec le regain de l’intérêt marqué pour l’Antiquité. Les moines ne font pas exception à ce renouveau. Loup de Ferrières ou Ra…
Comparison of machine learning and logistic regression as predictive models for adverse maternal and neonatal outcomes of preeclampsia: A retrospecti…
2022
IntroductionPreeclampsia, one of the leading causes of maternal and fetal morbidity and mortality, demands accurate predictive models for the lack of effective treatment. Predictive models based on machine learning algorithms demonstrate promising potential, while there is a controversial discussion about whether machine learning methods should be recommended preferably, compared to traditional statistical models.MethodsWe employed both logistic regression and six machine learning methods as binary predictive models for a dataset containing 733 women diagnosed with preeclampsia. Participants were grouped by four different pregnancy outcomes. After the imputation of missing values, statistic…

Abstract. We report on the developments that enabled the field deployment of a fully-automated aerosol mass spectrometer, specially designed for high-altitude measurements on unpressurised aircraft. The merits of the two main categories of real-time aerosol mass spectrometry, i.e. (a) single particle laser desorption and ionization, and (b) continuous thermal desorption / electron impact ionization of aerosols, have been integrated into one compact apparatus with the aim to perform in-situ real-time analysis of aerosol chemical composition. The demonstrated instrument, named ERICA (European Research council Instrument for the Chemical composition of Aerosols), operated successfully aboard t…
Cognitive and personality variables as predictors of sexism against women in Spanish adolescents
2022
Previous research on the antecedents of sexism against women have not considered simultaneously the effects of sex, personality, and cognitive variables (need for closure and critical thinking disposition) in relation to sexism. We evaluated whether in adolescence, these indicators could predict sexist attitudes towards women using structural models. The sample comprised 709 Spanish high-school students (mean age = 16.79). 51.5% were female. Sex (being male), need for closure and critical thinking were the most relevant predictors of sexism. The disposition to think critically is as relevant as the motivational dimension of cognition (need for closure) to predict sexism. Multi-group struct…

Studio preliminare su composizione e provenienza di ocra dalla sepoltura epigra-vettiana di Grotta d’Oriente A, Favignana (Egadi, Sicilia)
2022
La Grotta d’Oriente, sull’isola di Favignana (Egadi, Sicilia) ha restituito una serie di sepolture e resti umani ascrivibili all’Epigravettiano finale e al Mesolitico. La Sepoltura cosiddetta Oriente A, epigravettiana, è caratterizzata da un corredo fittile consistente in conchiglie e in un ciottolo con tracce di ocra rossa. Da un punto di vista della ricostruzione ar-cheologica e della definizione degli scenari di ecologia preistorica è molto importante la caratterizzazione chimica e la deter-minazione della provenienza di questo pigmento che, com’è noto, caratterizza molti scenari paleolitici. La ricerca presenta i dati preliminari dell’analisi SEM/EDS/EDAX dei pigmenti ocracei prelevati …
