Background: Head and neck melanomas (HNMs) have been associated with prognostic factors different from those on other locations. Objective: The goal of the present study was to compare the demographic and clinical characteristics and the outcomes of surgical treatment between patients with HNM and those with trunk and extremity melanoma (TEM). Material and methods: The clinical records of patients undergoing surgery for melanoma between October 2014 and April 2018 were retrospectively reviewed. Fifteen patients (22.3%) had HNM and 52 (77.7) presented TEM. Results: There were no differences in age between both groups (63.8 ± 21.1 versus 58.5 ± 16), but there was a trend toward higher percentage of men in the HNM group (80% versus 61.3%). Patients with HNM had lower tumor thickness than those with TEM (2.07 versus 5.5 mm), higher incidence of melanoma in situ [5 (33.3%) versus 8 (15.3%)]; lymph node resection was more common (33% versus 25%) as well as reconstruction of the primary defect with local and musculocutaneous flaps. During follow-up, two patients in the HNM group developed local recurrences that were excised and three presented distant metastases in the lung, small bowel and abdomen and finally died due to the disease. In the TEM group, one patient had local recurrence and five died due to systemic metastases. The sample size was not sufficient to assess statistically significant differences. Conclusion: Head and neck melanomas occur in a wide age range and stages and has some clinical differences with TEM. The defects produced after the excision of the primary lesion often require more complex procedures and should be managed with a multidisciplinary approach.

Published: November 2020

Tanulmányunkban egy új edukációs szemléletmódot mutatunk be, amelyet az elmúlt években kardiológiai rehabilitációs osztályon működtetett standard, manualizált csoportos program használata során sajátítottunk el. Az új szemlélet célja a betegek képessé tevése arra, hogy mindennapi életükben meg tudják oldani a betegségükhöz kapcsolódó problémákat. A betegek először igényeiknek megfelelő információkat kapnak betegségükről és kezelésükről. A betegséggel kapcsolatos reális viszonyulás és adekvát készségek megtanulása érdekében ösztönözzük a betegek aktív részvételét, a betegséggel kapcsolatos saját elképzeléseik és tapasztalataik megbeszélését. Az aktív részvétel segíti a betegek felelősségvállalását és a tanult képességek átültetését a mindennapi életükbe. A tanulmány második részében összefoglaljuk „A koszorúér-betegség oktatási programját”, amely saját gyakorlatunk alapjául szolgált. A program öt egymásra épülő modulból áll. Kialakítása multidiszciplináris együttműködés keretében történt, az életmód-változtatással foglalkozó részei egy széles körben használt egészségpszichológiai modellen alapulnak. Tapasztalataink szerint a betegedukációs program működtetését nagymértékben segíti strukturáltsága és részletes kidolgozottsága. Ez nemcsak feltétele az edukáció minőségének, hanem segítséget ad az egyes témák megbeszélése során kialakuló csoportdinamikai folyamatok kezeléséhez is.

A nátrium-glükóz-kotranszporter-2-gátlók mára a 2-es típusú diabetes mellitus gyógyszeres terápiájának egyik meghatározó elemévé váltak. Számos klinikai tanulmány igazolta ezen hatóanyagok pozitív hatását a kardiovaszkuláris mortalitás és morbiditás csökkentésében, így például az EMPA-REG OUTCOME az empagliflozin, a CANVAS, CANVAS-R-vizsgálatok a canagliflozin és a DECLARE-TIMI 58 a dapagliflozin esetében. Ezen kardioprotektív hatások magyarázatára számos hipotézis született. A szénhidrát-anyagcserére való hatásain túl a szervezet számos más részére is hatással vannak. Jelen összefoglaló közleményünkben a nátrium-glükóz-kotranszporter-2-gátlók főbb, szisztémás hatásait kívánjuk bemutatni.
Rationalizing Viral Drug Target Identification Using Computational Approaches : The SARS-CoV-2 Spike Glycoprotein S Case Study

Published: November 2020

COVID-19 emphasized the need for fast reaction tools to fight global biological threats such as viruses. Rapid drug discovery is one of the strategies for efficient social response. The success of a drug discovery campaign critically depends on the selected drug target, and the wrong target nullifies all the efforts to develop a drug. Viral drug target identification is a challenging problem, and computational methods can reduce the number of candidate targets. Here we present a structure-based approach to identify vulnerable regions in viral proteins that comprise drug binding sites. To detect promising binding sites, we take into account protein dynamics, accessibility, and mutability of the binding site, coupled with the putative mechanism of action of a drug. Applying to the SARS-CoV-2 Spike Glycoprotein S, we observed conformation- and oligomer-specific glycan-free binding site that is proximal to the receptor binding domain and comprises topologically important amino acid residues. Molecular dynamics simulations of Spike in complex with drug-like molecules docked into the binding sites revealed shifted equilibrium towards the inactive conformation compared to the ligand-free simulations. Small molecules targeting this binding site could prevent the closed-to-open conformational transition of the Spike protein, thus, allosterically inhibit the interaction with the human angiotensin-converting enzyme 2 receptor.
Nitrogen Heterocyclic Carbene (NHC) as a Versatile Oxygen Atom Acceptor that Abstracts Oxygen Atom from Aldehydes and CO2 A Computational Research
Authors: Ma Yumiao
Published: November 2020

The formal oxygen atom transfer (OAT) reaction with nitrogen heterocyclic carbenes (NHCs) as oxygen atom acceptor was designed and studied by density functional theory (DFT) calculations. Several properly designed NHCs were predicted to exhibit high reactivity towards the formal OAT reaction with aldehydes, in the presence of an intramolecular phosphine motif, which provides a new method to generate phosphorus ylide from aldehydes. Furthermore, the OAT reaction of NHCs with carbon dioxide (CO2) was predicted to occur at room temperature to release carbon monoxide, aided by an intramolecular nucleophile. These results may give insights about new methodologies for ylide preparation and CO2 reduction.

Authors: Ahsana Asif  , Subramanian E M G
Published: November 2020

A pulpectomy is the treatment of choice for pulpally involved primary teeth. Pulp therapy prevents the premature loss of primary teeth which could result in loss of arch length, an altered pathway of the eruption of primary teeth, development of aberrant habits. It also restores the dentition to a functional state. Endoflas is a newer obturation material which has a proven clinical success rate. There are various obturation techniques available in the literature. The systematic review aimed to extract and systematically identify the existing literature, which compares different obturation techniques used in the root canal treatment of primary teeth using endoflas as obturation material. The search was done using the MeSH terms and keyword search in the electronic databases, including PubMed, Cochrane, LILAC, Sigle, Science Direct and Google scholar. A total of 13 articles were chosen after the initial screening of the title. Then based on the inclusion and exclusion criteria and the availability of the full texts, a total of 3 articles were included.  This systematic review concludes that there is a need to update the existing literature to find out the beat ideal obturation technique which can provide void-free and ideal obturation of the root canal of the primary teeth using Endoflas.

Published: November 2020

En el presente estudio se describe la estructura de la comunidad fitoplanctónica y su distribución en el Estrecho de Gerlache (EG) durante el verano austral 2018-2019. Se realizaron arrastres verticales de 200 m a la superficie a través de una red Bongo equipada con flujómetro. Las muestras se fijaron en Lugol básico en una relación 100:1. Muestras adicionales para el análisis de nutrientes y clorofila-a se tomaron a través de una roseta oceanográfica. Mediante un análisis de funciones empíricas ortogonales estandarizadas el Estrecho de Gerlache fue regionalizado en cuatro regiones, usando los datos de riqueza y químicos. De las regiones identificadas se ubicaron dos en el norte, una en el centro y otra en el sur. En términos de riqueza se identificaron 40 taxones representados por 28 diatomeas, 11 dinoflagelados y un silicoflagelado. La mayor riqueza y abundancia se encontró en la región central siendo las diatomeas el grupo dominante en todas las estaciones. Las especies Corethron criophilum y Porosira glacialis representaron el mayor aporte a la comunidad. Los dinoflagelados formaron el segundo grupo más distintivo en el área de estudio, representado por las especies Protoperidinium pyrum y Prorocentrum minimun. Por otra parte, los silicoflagelados con la especie Dictyocha sp. fue el grupo con menor representatividad en el área, sin embargo, su mayor abundancia se observó en la región norte. Se observaron diferencias en la estructura de la comunidad, con dominancia de las diatomeas sobre los demás grupos identificados; dichos cambios pueden obedecer a las técnicas analíticas empleadas y a la variabilidad interanual.

Guardianship is the supervision of children who are no longer under the authority of their parents, and the management of objects or property of the children carried out by the guardian. In carrying out their duties, the guardian is supervised by the guardian supervisor, which based on Article 366 Indonesian Civil Code, the authority is given to the Weskamer. This office is one of the technical implementation units under the Ministry of Law and Human Rights. However, the supervision process can hardly be carried out by the Weskamer, that relates to its role that requires synergy with the role of other institutions. It shows that there is disharmony in the implementation of protection of children's assets in guardianship, which eliminates the element of supervision by the state through the Weskamer. Therefore, an idea is needed in harmonizing the protection of children's assets in guardianship through strengthening the role of guardian. This research uses normative method which is a part of legal research. Normative legal research aims to find solutions to juridical problems that arise from legal issues and provide prescriptions on these legal issues. Based on the results of the study, systematic and concrete steps are needed to improve the rules by harmonizing laws as well as institutions regarding the protection of the assets of the children by strengthening the role of guardian supervisor.

Published: November 2020

In the early 1990s, Romania had a high incidence of hepatitis B, with over 30 cases per 100,000 population annually. The disease represented a serious public health problem, especially for children. As a result, public health measures were introduced during the 1990s such as the enforcement of the use of single-use needles and a routine vaccination programme for children and health workers. This paper describes the change in incidence of HBV infection in Romania from the late 1980s until 2005, and demonstrates the impact of those measures. They have lead to a dramatic decrease in hepatitis B incidence across the country: overall, the incidence has decreased from 43 per 100,000 in 1989 to 8.5 per 100,000 in 2004. The decrease has been most prominent in children under 15, dropping from 81 to 11 per 100,000 population and year during that period.

Authors:   Ukhta State Technical University, Ignatik Anatoly A.
Published: November 2020

Theoretical and experimental study of the stress-strain state of a pipeline under the influence of two types of loads was carried out: 1) bending force in vertical plane; 2) combined action of bending force in vertical plane and internal pressure. The experiments were performed on a pipe sample: steel grade Ст3, outside diameter 114 mm, wall thickness 4.5 mm, length 0.94 m. Hoop and longitudinal strains were measured in different areas of the pipe sample wall under the bending force in the vertical plane. To determine other parameters of the pipe stress-strain state the theories of thick-walled and thin-walled cylindrical shell, the Hooke’s law, the Zhuravsky–Vlasov formula for calculating the greatest shear stress in a circular tube, the principle of superposition were used. The distributions of the stress-strain state parameters (hoop, longitudinal, radial strains; hoop, longitudinal, shear stresses; von Mises stress) of the pipe sample wall around the perimeter of different pipe cross sections are found. It is revealed that hoop and shear stresses have a significant effect in the considered cases of loading. The values of hoop and shear stresses should be taken into account when calculating von Mises stress and assessing strength of the main pipeline according to the maximum-distortion-energy theory.

Published: November 2020

The authors consider the problem of the computational investigation of cathodic protection electric fields measured for an underground pipeline taking into account the anisotropic nature of soil specific electrical conductivity. A computational experimental method was used to compare the figures for anisotropic soils against the current distribution for a homogeneous half-space; the influence of anisotropy factors and the azimuth conductivity tensor rotation angle for pipeline-enclosing soil on the electrical parameters of cathodic protection of the pipeline were investigated. It was demonstrated that protective capacity can vary significantly for areas close to the drainage points of cathode stations and for defective segments. It was concluded that there is a need to take into account terrain structure (its electrical anisotropy) when there are prerequisites of soil lamination/fracturing, or if its specific electrical conductivity contrast in the lateral direction is in excess of 2–2.5 times.

EXPEREMENT POLYGON-70
Authors: Koshlyakov M.N.
Published: November 2020

In 1970, an experiment named Polygon–70 was carried out by Russian oceanographers in the tropical zone of the North Atlantic. During this experiment, seventeen autonomous buoy moorings were deployed for the period of half-a-year to measure ocean currents in the ocean layer ranging from the surface to the depth of 1500 m. The outcome of this work was the discovery of what later became known as “synoptic eddies of the open ocean”. It revealed the scale, the nature of time variability and energy of these vortices, as well as an interpretation of the observed phenomena from the point of view of the theory of Rossby waves. It was suggested, that the emergence of the vortices was due to baroclinic instability of large-scale flow. These results of Polygon–70 expedition showed its outstanding value and provided basis for further development of studies of ocean vortices.

Agriculture in Indonesia, one of which is food crop agriculture, food crops are dominated by rice and corn products. Indonesia, which was previously known as the most significant food-producing country in the world, is currently experiencing a shift, where Indonesia's rice production has decreased compared to China. The condition of Indonesia's rice and corn production in the world will have an impact on the status of rice and corn in Indonesia, especially in East Java, East Java is a region that has the potential to produce rice and corn compared to the other area in Indonesia, on the other hand, because of Indonesia's demand for rice and corn large enough. The occurrence of COVID 19 has an impact on all aspects of the world and all sectors, one of which is food crops, how the effects of COVID 19 on food crop agriculture in East Java, the results of the study are the behavior of farmers in East Java relatively no difference before the occurrence of COVID 19 and after COVID 19, farmers still work as usual. Rice supply at the level of the farmer community is still sufficient because farmers have harvested a month in March 2020. In Bangkalan Madura the village government has the  policy to carry out the harvest by renting harvest tools to anticipate COVID 19, while in Gresik and Lamongan areas farmers continue to do the harvest without assistance harvester. The role of advisory counselors is needed by farmers, this is because extension agents can become counselors of the COVID 19 problem in the community during a pandemic like this, and this is in line with research (Adawiyah, Sumardjo, and Mulyani 2018) that farmers' facilitators influence the adoption of new technologies. With the COVID 19 outbreak, the brothers of the farmers returned home because of the culture of going back or also because the factories, shops, restaurants where they work have been close, this is a burden for farmers.

It is known that the power consumption and efficiency of an equipment owes directly to its power factor. The lower the power factor of the equipment the more the energy consumption of such equipment and vice-versa.Hence, the need to develop an equipment to measure accurately the operating power factor of domestic and industrial equipment and appliances [1]. The operating principle of this power factor meter design is based on Zero Crossing detection principle, the principle is utilized using Arduino Nano,instrument transformers, LM324 operational amplifier, generic resistor, generic XOR Gate 7488 and 2X16LCD.The input current and voltage signal is taken by the transformers and sent to the op- amp which carries out the zero crossing detection in order to get the time difference after which the microcontroller does the calculation to determine the power factor and the deficit reactive power which is then displayed on an interface [2].
