The feed additive L-cysteine ​​in a therapeutic dose was used for 2 months against the background of poisoning of white rats with a combination of lead and cadmium at a level of 10 MPC (50 and 5 mg / kg, respectively). The maximum accumulation of heavy metals was found in the kidneys (Pb up to 8,15 mg / kg, Cd 2,51 mg / kg) and liver (Pb up to 7,44 mg / kg, Cd 1,80 mg / kg) of rats. With the introduction of L-cysteine ​​into the feed, the content of lead decreased by 2 times and cadmium by 2 ... 4 times in all investigated organs. Thus, L-cysteine has shown a fairly complete protective effect in heavy metal poisoning and can be recommended as a means that can reduce heavy metal (HM) intoxication.

Management of Non-Vital Open Apex in A Lateral Incisor Using Calcium Hydroxide and Reverse GP Cone Cold Lateral Compaction in A General Practice Setting
Authors: Al-Saffar Haider
Published: March 2021

Although dental trauma is poorly managed by general dental practices, it is important to follow appropriate steps to achieve optimal results. This case report outlines the management of non-vital immature teeth with calcium hydroxide and reverse Gutta Percha (GP) cone cold lateral compaction to achieving endodontic success. Even though it is a disputed technique, if proper conditions are provided, the root development continues to preserve a functionally fit and sound tooth on the arch of a young adolescence, avoiding extensive surgical and prosthetic procedures to replace a potentially compromised tooth. This case report highlights the beneficial effects of both calcium hydroxide and Chlorhexidine-dygluconate (CHX), which are far to be obsolete in the field of apexification or even regenerative dentistry as a whole.The 11 years old male presents post-traumatic necrosis in the upper left lateral incisor (tooth 2.2) which is dressed with calcium hydroxide, achieving the disinfection of the root canal, remission of the apical periodontitis and complete root formation 1 year later. The importance of the use of biocompatible materials as calcium hydroxide and CHX are emphasized in this case in which, although, no modern regenerative procedures and materials were used, the results are more than satisfactory. This report will look into the management of a non-vital immature lateral incisor with a reverse GP cone lateral compaction to achieving a successful apical and canal seal radiographically.

Authors: Trivosa Vonda
Published: March 2021

Cleft lip and palate is a common congenital malformation in the oral and maxillofacial regions. According to epidemiological investigation, the incidence rate is about 1.625%, and the incidence rate is high in poor areas and rural areas. Cleft lip and palate mainly involve the upper lip, hard palate, soft palate and nose, which can damage the appearance of children, affect pronunciation, swallowing and chewing, and also bring different degrees of psychological damage to children in the growth stage. Therefore, we should actively carry out sequential treatment and participate in the treatment work through multi-disciplines. Based on restoring the oral and maxillofacial function and health of children, we should also pay attention to their aesthetic needs, enhance the treatment confidence of parents and children, and lay the foundation for the follow-up repair treatment. Most patients with cleft lip and palate are complicated with malocclusion. Orthodontic treatment is an important part of the treatment of cleft lip and palate. The orthodontic treatment of cleft lip and palate can be divided into five periods: newborn period, deciduous dentition period, mixed dentition period, permanent dentition period and combined orthodontic and orthognathic treatment period. Presurgicalnasoalveolar molding (PNAM) was used to reduce the severity of facial deformity in children with cleft lip and palate. This article discusses the therapeutic effect of newborn PNAM according to clinical cases. Objective to study the opportunity and current situation of PNAM in the treatment of children with cleft lip and palate, and to provide a favorable reference for clinical orthodontists, emphasizing the close communication between various disciplines.

Amplitudenmodulation (AM) bei Windenergieanlagen/Amplitude modulation (AM) in wind turbines – effect of AM on people, Direction and distance dependence
Authors: Martinez Sergio , Pies Kai , Fennel Florian , Ferreira Anne-Kathrin
Published: March 2021

Im Rahmen dieses Beitrags wird zunächst ein Ansatz zur Quantifizierung der Lärmwirkung von WEA Geräuschen auf den Menschen als Belästigungsfunktion (Annoyance) dargelegt. Das Modell wird durch eigene Hörversuche und zusätzlich anhand von Ergebnissen anderer Autoren validiert. Prinzipiell kann hieraus auch eine Berücksichtigung der Belästigung als Pegelzuschlag abgeleitet werden. Im zweiten Teil der Arbeit wird die Schallausbreitung sowohl von einzelnen WEA (im Nahbereich) als auch von Windparks (Fernbereich 600 m bis über 1000 m zum Immissionsort) in Bezug auf die Richtungs- und Entfernungsabhängigkeit der Amplitudenmodulation (AM) der WEA Geräusche untersucht. Hierbei spielen zum einen die Pegeländerungen durch die Richtwirkung, zum anderen die Pegeländerungen aufgrund des Dopplereffektes eine wichtige Rolle [7]. Die AM ist in dieser Kombination nicht nur im Nahbereich der WEA eine fundamentale Komponente des typischen WEA-Geräusches. AM zeigt sich deutlich in allen Windrichtungen auch in Entfernungen über 1000 m. Das gilt sowohl für Wetterlagen, bei denen die WEA-Geräusche dominierend sind als auch bei relativ geringen Rotordrehzahlen, bei denen sich die AM ebenfalls ausbildet. Bei Windparks tritt bei der Überlagerung der Beiträge der einzelnen WEA ein sogenannter Windparkeffekt auf.

The third of requirements in this article on the question of origin of people is to keep in mind that the anthropological type and language of the ancestors of an ethnos never coexist with the language and type of the ethnos. This is because in the early stages of the history of ethnogenesis, ethnic units, especially their language and type, have not been formed yet. The concepts of language, type, and ethnic unity are realities of different periods, and it has been argued that the process of their formation did not take place at the same time.

Will the Mars Helicopter Induce Local Martian Atmospheric Breakdown?
Authors: Farrell W. M. , McLain J. L. , Marshall J. R. , Wang A.
Published: March 2021

Any rotorcraft on Mars will fly in a low-pressure and dusty environment. It is well known that helicopters on Earth become highly charged due, in part, to triboelectric effects when flying in sandy conditions. We consider the possibility that the Mars Helicopter Scout (MHS), called Ingenuity, flying at Mars as part of the Mars 2020 Perseverance mission, will also become charged due to grain-rotor triboelectric interactions. Given the low Martian atmospheric pressure of ∼5 Torr, the tribocharge on the blade could become intense enough to stimulate gas breakdown near the surface of the rotorcraft. We modeled the grain–blade interaction as a line of current that forms along the blade edge in the region where grain–blade contacts are the greatest. This current then spreads throughout the connected quasi-conductive regions of the rotorcraft. Charge builds up on the craft, and the dissipative pathway to remove charge is back into the atmosphere. We find that for blade tribocharging currents that form in an ambient atmospheric dust load, system current balance and charge dissipation can be accomplished via the nominal atmospheric conductive currents. However, at takeoff and landing, the rotorcraft could be in a rotor-created particulate cloud, leading to local atmospheric electrical breakdown near the rotorcraft. We especially note that the atmospheric currents in the breakdown are not large enough to create any hazard to Ingenuity itself, but Ingenuity operations can be considered a unique experiment that provides a test of the electrical properties of the Martian near-surface atmosphere.
Effects of stream permanence on stonefly (Insecta, Plecoptera) community structure at Mammoth Cave National Park, Kentucky, USA
Authors: McRoberts Taylor , Grubbs Scott
Published: March 2021

Stoneflies (Plecoptera) are often associated with inhabiting cold perennial streams, but many species also inhabit intermittent streams that experience reduced or lack of flow during summer and autumn. In this study, the influence of stream permanence on stonefly assemblage composition and spatial distribution at Mammoth Cave National Park, Kentucky, USA, was addressed, based on a 14 month sampling regime from the fullest range of stream sizes and habitable flow regions available. Adult stoneflies were collected monthly from 43 sites at the Park plus an additional two sites at the near-adjacent Western Kentucky University Green River Preserve. Collections were done from December 2018–November 2019 using a standard timed protocol with beating sheets for adults and once in December 2019–January 2020 for larvae. Stream sites were assigned one of five category types: perennial spring runs, perennial spring seeps, upland perennial streams, perennial riverine and summer dry runs. In total, 34 species were collected. The most prominent difference in stonefly community structure was between spring runs, spring seeps and summer dry streams vs. upland perennial streams. Approximately 88% of species collected had univoltine-fast life cycles and 79% likely had an extended period of egg or larval diapause. Due to the predominance of small upland perennial and summer dry streams, species commonly typically found in larger lotic systems are fundamentally filtered out of the region due to the lack of available habitats. Species able to survive in intermittent habitats do so by life history adaptations including to survive desiccation as larvae or eggs.

In this work, we study the problem of $ p- $th moment global exponential stability for functional differential equations and scalar chaotic delayed equations under random impulsive effects. Meanwhile, the $ p- $th moment global exponential synchronization for the proposed equations is also discussed, whereas the main results are proved by using Lyapunov function and Razumikhin technique. Furthermore, the impact of fixed and random time impulses are presented by applying the results to Mackey Glass blood cell production model and Ikeda bistable resonator model. Finally, the effectiveness of fixed and random impulses are depicted via graphical representations.

La restauration des œuvres d’art et tout particulièrement celle des statues dans les lieux de culte du monde grec antique peut être perçue à travers les sources littéraires et épigraphiques qui laissent entrevoir l’implication d’artisans spécialisés, mais également l’implication financière et institutionnelle des organismes civiques concernant la remise en état des sanctuaires et des éléments du culte. On envisage ici plusieurs documents, principalement aux époques classique et hellénistique (ive-ier siècles av. J.-C.).
La thérapéia des sculptures en Grèce ancienne : le témoignage des sources textuelles
Authors: Leka Evridiki
Published: March 2021

L’étude des textes littéraires et épigraphiques constitue le point de départ indispensable de l’enquête sur la restauration d’œuvres sculptées dans l’Antiquité. Quoique nous ne connaissions à ce jour aucun traité antique sur la conservation et la restauration en général, et encore moins concernant les sculptures, le bilan des informations, forcément ponctuelles et dispersées, voire parfois difficiles à interpréter, qui sont contenues dans les sources textuelles, nous conduit à penser que les Anciens se souciaient beaucoup d’entretenir et de restaurer les œuvres sculptées. Le caractère de leur démarche était cependant très différent du nôtre, comme l’attestent à la fois la nomenclature et les types des traitements, la nature des œuvres traitées, les circonstances et les lieux où les opérations avaient lieu, ainsi que l’identité des personnes qui en étaient responsables.
(Re)peindre, dorer, cirer. La thérapéia en acte dans la sculpture grecque hellénistique
Authors: Bourgeois Brigitte
Published: March 2021

Expression de piété, la thérapéia, le « service » rendu aux effigies sacrées dans la Grèce antique, désignait dans un sens profane des opérations liées à la conservation des œuvres, visant à remettre en bon ordre la statue aux mains d’artisans choisis pour leur savoir-faire. L’article présente trois dossiers de sculptures en marbre d’époque hellénistique qui permettent d’approcher concrètement la réalité des gestes opérés en matière de traitements de surface tels que peindre, nettoyer, repeindre, dorer, ou encore appliquer un vernis de cire d’abeille selon l’opération de la ganôsis. Les études de cas concernent une statuette d’Asclépios (Dresde), la statuette féminine dorée de la Maison des Masques (Délos) et le portrait dit de Bérénice II (Musée royal de Mariemont).
La ville d’Akrotiri : une source exceptionnelle d’information sur l’activité textile au milieu du second millénaire au cœur du monde égéen
Authors: Spantidaki Stella , Moulherat Christophe
Published: March 2021

Akrotiri, située sur l’île de Santorin, est une ville exceptionnellement bien conservée grâce à une éruption volcanique qui s’est produite au milieu du xviie siècle avant notre ère. Elle a livré une grande variété d’objets du quotidien, dont plusieurs liés à la production des textiles, témoins d’une activité florissante.Nos sources d’information sont multiples, qu’il s’agisse de tablettes rédigées en Linéaire A relatives à la production et aux échanges de tissus, ou de peintures murales sur lesquelles est notamment représentée une grande diversité de vêtements. Les outils de filage et surtout la concentration de pesons de tissage témoignent d’une organisation de la production dans des espaces spécifiques.Les tissus conservés ont été réalisés avec des matériaux d’origine végétale et animale et présentent parfois des traces de décoration.La découverte de feutre végétal, de filets de pêche, d’un cocon de soie et d’une grande variété de ficelles et cordes employées sous différentes formes livrent des informations sur la diversité des activités liées au travail des matières organiques et en particulier des textiles, confirmant ainsi la réalité des représentations que nous livrent les peintures murales.

L’ouverture des nouvelles salles consacrées à l’Orient romain au musée du Louvre a été l’occasion de restaurer un linceul daté du iie siècle ap. J.-C. conservé au département des Antiquités égyptiennes avec son masque-plastron. La présentation de cet ensemble qui combine, fait assez rare dans un musée, le plastron avec son linceul d’origine, a supposé de réfléchir à la façon dont ce dernier était agencé sur la momie originale afin de lui restituer sa position la plus exacte possible. Une enquête historique pour trouver des linceuls comparables a, par conséquent, été nécessaire avant de procéder à la restauration proprement dite. Cette dernière a impliqué un travail préparatoire et la création d’un prototype pour ajuster la forme du montage aux fragments du linceul anciennement restaurés.

Les observations au microscope électronique à balayage (MEB) montrent qu’ils contiennent des particules dont les dimensions sont de l’ordre de 0,1 µm pour les verres opalescents, nettement plus grandes dans le cas des verres opaques. La nature de ces particules a été déterminée par spectroscopie par dispersion d’énergie (energy dispersive spectroscopy – EDS) et par diffraction des rayons X (DRX). Dans certains cas, des solutions classiques (cassitérite, antimoniate de calcium) ont été utilisées. Dans d’autres cas, des compositions plus complexes (arséniate de plomb pouvant contenir du phosphore, du calcium…), voire pratiquement inconnues (antimoniate de potassium et silicium, phosphate de sodium et calcium) ont été mises en évidence. Le microscope à balayage équipé d’un canon à effet de champ1 est un outil précieux pour visualiser la phase opacifiante, en déterminer la granulométrie et en estimer la composition.
Les Trois baigneuses de Courbet (musée du Petit Palais) : restauration et découvertes
Authors: Collet Isabelle , Sindaco-Domas Claudia
Published: March 2021

Courbet a peint les Trois baigneuses vers 1865-1868, sans pouvoir achever sa composition après son départ en exil en Suisse. L’œuvre, restée à Paris, est entrée dans les collections du Petit Palais en 1909 grâce à une donation de Juliette Courbet. Ce tableau présente la particularité d’être peint à l’huile sur papier et d’avoir été agrandi en cours d’exécution. Restauré en 1973, puis marouflé sur une nouvelle toile en 1977, il a fait de nouveau l’objet d’une intervention en 2014. Ce travail sur la couche picturale a été précédé d’une étude au C2RMF qui a permis de mieux comprendre la genèse de l’œuvre et son évolution : d’une figure d’odalisque présentée sur un format horizontal, elle est devenue une composition à trois personnages, en format vertical. La restauration de la couche picturale menée en 2014 au Petit Palais a été l’occasion d’examiner de plus près la technique picturale de Courbet, de la confronter à d’autres peintures de l’artiste et d’en restituer la qualité intrinsèque en respectant son caractère inachevé.
Biomarkers for Predicting Cytokine Release Syndrome following CD19-Targeted CAR T Cell Therapy
Authors: Tedesco Victor E. , Mohan Chandra
Published: March 2021

Chimeric Ag receptor (CAR) T cell therapy has shown astonishing potency in treating a variety of hematological malignancies in recent years. Along with this lifesaving potential comes the life-threatening toxicities of cytokine release syndrome (CRS) and neurotoxicity. This work seeks to consolidate biomarker candidates with the potential to predict the severity of CRS and neurotoxicity in patients receiving CD19-targeted CAR T cell therapy. In this systematic review, 33 clinical trials were evaluated for biomarkers that can predict the severity of posttreatment CRS and neurotoxicity. CRS and neurotoxicity occurred in 73.4 and 37% of the reviewed patients, respectively. Identified biomarker candidates included tumor burden, platelet count, C-reactive protein, ferritin, IFN-γ, IL-2, IL-6, IL-8, IL-10, IL-15, and TGF-β. Combinatorial algorithms based on cytokine levels and clinical parameters show excellent promise in predicting CAR-T-cell-therapy–associated toxicities, with improved accuracy over the component biomarkers.

Background

The total number of people affected by dementia worldwide is increasing rapidly. Recent studies provided evidence for the contribution of modifiable risk and protective factors to dementia risk. Although healthcare professionals could play an essential role in informing the general public about the relationship between lifestyle and dementia, it is unclear what they know about this relationship. Therefore, this study assesses the awareness of dementia risk reduction among current and future healthcare professionals.

Design and methods

An online survey was carried out among 182 healthcare students from Maastricht University and 20 general practitioners (GPs) and practice nurses in Limburg, The Netherlands. The survey assessed the knowledge about risk and protective factors of dementia and identified needs, wishes and barriers concerning dementia risk reduction strategies.

Results

The majority of current (75.0%) and future (81.9%) healthcare professionals indicated that dementia risk reduction is possible. Among students, awareness of cardiovascular risk factors of dementia ( e.g., coronary heart disease (44.5%), hypertension (53.8%)) was low. Most participants (>70.0%) would like to receive more information about dementia risk reduction.

Conclusions

The majority of current and future healthcare professionals were aware of the relationship between lifestyle and dementia risk. However, there are still substantial gaps in knowledge regarding individual dementia risk factors. Given the essential role of healthcare professionals in providing lifestyle advice, there is a need to increase awareness by providing educational programs focused on dementia risk reduction.
Program Directors' Perception of the Importance of Soft Skills in Athletic Training
Authors: Kutz Matthew R. , Stiltner Sara
Published: March 2021

Context

Soft skills have been reported to be a necessary aspect of athletic training education and clinical practice. However, almost no empirical research has explored the level of importance of soft skills or the frequency with which they are evaluated within athletic training education.

Objective

To delineate the perceived importance of soft skills within athletic training education and describe the frequency with which those soft skills are evaluated within athletic training programs.

Patients or Other Participants

Four hundred eight program directors (PDs) of Commission on Accreditation of Athletic Training Education–accredited athletic training programs were invited to patriciate; 122 responded and 108 of those responses (88.5%) were usable (64% PDs of baccalaureate programs, 28% PDs of professional masters, 8% did not disclose), yielding a 26.5% response rate. All 10 National Athletic Trainers' Association districts were represented, with the highest representation (26%) from District 4. A majority of respondents were female (57%). Most respondents (79%) had 11 or more years of experience (33% of those ≥21 years) as an athletic training educator, and 98% of respondents identified as white/non-Hispanic.

Main Outcome Measure(s)

Importance and frequency of soft-skill evaluation were measured using the Athletic Training Soft-Skills Assessment Instrument (ATSSAI). Data of perceived importance and frequency of evaluation were organized by various demographic variables and between scale dimensions.

Results

The ATSSAI psychometric analysis yielded satisfactory internal consistency and validity (α = .84 to .93). Paired-samples t test indicated significant differences between the ATSSAI Perceived Importance and Frequency of Evaluation scales (mean = 1.65 ± .47 versus mean = 3.29 ± 1.17, P = .000; Cohen d = 1.83). Pearson r correlation showed a positive relationship between perceived importance and frequency of evaluation, r = 0.81. Independent-samples t tests revealed female PDs perceived 2 soft skills (18%; observant and exact and prepared and adaptable) as more important (t99 = 2.12 and 2.18, P = .31 and .37) than did male PDs and evaluated 3 (27%; decisive and confident, prepared and adaptable, and observant and exact) more frequently (t99 = 2.35–2.50, P = .14–.21) than did male PDs.

Conclusions

All soft skills identified as necessary for inclusion in athletic training education were perceived to be very or extremely important by PDs. However, those same soft skills were not evaluated as often as their importance might suggest. Dependability and responsibility was the most important and most frequently evaluated soft skill (mean = 1.31 ± .51 and 2.21 ± 1.30, respectively). Female PDs generally perceived soft skills as more important and reported evaluating them more frequently. Soft-skill development is a tacit-based phenomenon that contributes to leadership effectiveness and clinical preparedness.
Neoproterozoic-Cambrian stratigraphy of the Mackenzie Mountains, northwestern Canada, part III:
measured sections from Neoproterozoic and Cambrian formations, NTS 96-D
Authors: MacNaughton R B
Published: March 2021

Four previously undescribed measured sections are documented through lower and middle Cambrian (Series 2 and Miaolingian) strata of the eastern Mackenzie Mountains, Northwest Territories. These include three exposures of the Mount Clark Formation that are
complete or nearly so, and a complete section through the overlying Mount Cap Formation. As in previous reports, Mount Clark Formation is dominated by quartz arenite, with variable bioturbation. Mount Cap Formation is heterolithic, dominated by dark-weathering shale and paler-coloured carbonate
rocks. A section through the Neoproterozoic McClure Formation (Katherine Group) also is included, and contains abundant fine-grained siliciclastic strata with lesser sandstone and a distinctive orange-weathering carbonate. Correlations between these sections and one previously documented show the
influence of late Neoproterozoic folding, reflected in erosional truncation of the McClure Formation beneath the Cambrian succession, as well as stratigraphic variations in the Cambrian units that reflect the influence of the Mackenzie Arch.

Published: March 2021

Background:

There are few studies on unplanned extubation (UE) in pediatric intensive care units (PICU). This study is to identify factors associated with UE in PICUs.

Subjects and Methods:

In this observational study, the data of UE from January 1, 2013, to May 31, 2019, in a level-4 PICU were analyzed with an objective to study the etiology of UE and its impact on therapeutic outcomes.

Results:

Of 7079 patients hospitalized in PICU, 1721 were invasively ventilated (mean ventilator days 4.33 days). UE occurred in 39 patients (2.26% of intubated patients) at 0.52 UE events per 100 ventilation days. The median age was 14 months. The most common cause of UE was inadequate sedation (n = 24, 61.53%), endotracheal tube suctioning (n = 05, 20.8%), one during adjusting ET tube (4.1%), one during central venous line insertion (4.1%), and one during Foley's catheter insertion (4.1%) and 7 unexplained (29.1%). As long as the appropriate nurse: patient ratio was maintained, the incidence of UE was un-affected by day versus night shift or high versus low bed occupancy rates. Re-intubation rate in UE cohort was higher (74.35%) than planned-extubation cohort 0.11% (P < 0.001). All re-intubations were within 2 h of UE. Most common cause of re-intubation following UE was respiratory distress (72.41%), stridor (17.24%), and apnea (10.34%). Re-intubations following UE showed higher incidence of ventilator-associated pneumonia but statistically not significant (P = 0.54).

Conclusion:

UE is associated with a significantly high incidence of re-intubations and associated complications arising from re-intubations. Maintaining a pool of skilled nurses in adequate nurse-to-patient ratio may play an important role in preventing UE. UE can be minimized by optimizing sedation and monitoring during common ICU procedures. Multicentric studies are warranted to design a uniform standard of care of ventilated patients aimed at reducing the incidence of UE.
Successful use of tocilizumab in the treatment of multisystem inflammatory disease of childhood refractory to intravenous immunoglobulin and glucocorticoids
Authors: Oswal Jitendra S , Sarangi Bhakti , Shankar Guruprasad Hassan , Sharma Varsha
Published: March 2021

Multisystem inflammatory syndrome in children (MIS-C) is one of the many challenges thrown by the ongoing SARS CoV-2 pandemic. A high index of suspicion is warranted for the diagnosis of MIS-C as presenting features overlap with Kawasaki disease and toxic shock syndrome. The treatment guidance is empirical with consideration of intravenous immunoglobulin (IVIG) and glucocorticoids. However, treatment of refractory MIS-C remains eluded. We describe here a 7-year-old boy with MIS-C refractory to IVIG and pulse methylprednisolone who responded to interleukin-6 inhibition using tocilizumab.
Mixed data in inverse spectral problems for the Schrödinger operators
Authors: Hatinoğlu Burak
Published: March 2021

We consider the Schrödinger operator on a finite interval with an

L^1

-potential. We prove that the potential can be uniquely recovered from one spectrum and subsets of another spectrum and point masses of the spectral measure (or norming constants) corresponding to the first spectrum. We also solve this Borg–Marchenko-type problem under some conditions on two spectra, when missing part of the second spectrum and known point masses of the spectral measure have different index sets.
