OBJECTIVE

Few studies have compared midregional proatrial natriuretic peptide (MR-proANP) and N-terminal probrain natriuretic peptide (NT-proBNP). We compared their value as risk markers for all-cause mortality and cardiovascular (CV) and renal complications in individuals with type 1 diabetes.

RESEARCH DESIGN AND METHODS

MR-proANP and NT-proBNP were measured in 664 individuals. Hazard ratios (HRs) were assessed per doubling of NT-proBNP or MR-proANP for risk of a composite of ischemic events, heart failure (HF), a combined renal end point of end-stage kidney disease (ESKD), decline in estimated glomerular filtration rate (eGFR) ≥30%, and all-cause mortality or individual end points. Adjustments included CV risk factors and addition of MR-proANP or NT-proBNP.

RESULTS

Median follow-up was 5.1–6.2 years. MR-proANP was associated with higher risk of all-cause mortality (n = 57; HR 1.7, 95% CI 1.1–2.7), combined CV end point (n = 94; 1.6, 1.1–2.2), HF (n = 27; 2.8, 1.5–5.2), combined renal end point (n = 123; 1.6, 1.2–2.1), and ESKD (n = 21; 3.1, 1.2–7.8) independent of CV risk factors (P ≤ 0.02). After addition of NT-proBNP, significance for all end points was lost. A doubling of NT-proBNP was associated with higher risk of all-cause mortality (HR 1.5, 95% CI 1.2–1.8), the combined CV end point (1.3, 1.1–1.5), HF (1.7, 1.3–2.1), and the combined renal end point (1.3, 1.1–1.4) independent of CV risk factors (model 2 [P < 0.001]) and MR-proANP (model 3 [P ≤ 0.03]). There was no association with decline in eGFR ≥30% (n = 93).

CONCLUSIONS

Higher NT-proBNP was independently associated with all-cause mortality, CV disease, HF, and the combined renal end point. MR-proANP was associated with all end points but decline in eGFR, although not independent of NT-proBNP. MR-proANP may contribute to the predictive value of NT-proBNP for risk stratification in type 1 diabetes.
Classification and chronology of the collection of arrowheads from ash-hill found in hillfort of the Scythian Cultural Circle in Chotyniec, site 1, Jarosław district
Authors: Burghardt Marcin
Published: December 2020

he paper presents the results of a typo-chronological analysis of arrowheads from the ash-hill found in the hillfort of the Scythian cultural circle in Chotyniec, site 1, Jarosław province. During the 2016-2018 excavation campaigns, 38 such specimens were discovered. All arrowheads from Chotyniec could be linked to the Northern Black Sea region, where they have good analogies. Thanks to a detailed chronological analysis of the arrowheads, using the data from quiver sets from Scythian graves, it was possible to establish that they could be dated between the end (or maybe even the second half) of the 7th century to the middle of the 6th century B.C. Referring to chronological schemes of the Scythian cultural circle, the described collection of artefacts would be linked to the final phases of archaic Scythia (stage ESC-3), which are synchronous with the second half of the HaD1 and the HaD2 phase in the periodization of cultures of Central Europe.
The Chotyniec agglomeration and its importance for interpretation of the so-called Scythian finds from south-eastern Poland
Authors: Trybała-Zawiślak Katarzyna
Published: December 2020

Artefacts of eastern provenance, so-called Scythian ones, have been registered in Polish areas for a long time. In the western part of Polish lands, they were most often linked with Scythian invasions, and this explanation of finds was emphasized by destroyed settlements. In eastern Poland, the presence of similar artefacts, was interpreted rather in the context of contacts with the forest-steppe zone, and their almost neighbourly character was confirmed by characteristic decorations and parts of clothing. Discoveries related to the fortified settlement in Chotyniec (south-eastern Poland), together with accompanying settlements from the same time, allow for a slightly different view on the so-called Scythian finds recorded within the eastern groups of the Lusatian circle. The agglomeration should be treated as the farthest northwest enclave of the forest-steppe variant of the Scythian culture and as transmitter of certain cultural patterns. It is also a cultural phenomenon that plays a key role in the reception of the so-called eastern cultural elements.

The article discusses the results of the latest interdisciplinary research of Czermno stronghold and its immediate surroundings. The site is mentioned in chroniclers’ entries referring to the stronghold Cherven’ (Tale of Bygone Years, first mention under the year 981) and the so-called Cherven’ Towns. Given the scarcity of written records regarding the history of today’s Eastern Poland, Ukraine, and Belarus in the 10th and 11th centuries, recent archaeological research, supported by geoenvironmental analyses and absolute dating, brought a significant qualitative change. In 2014 and 2015, the remains of the oldest rampart of the stronghold were uncovered for the first time. A series of radiocarbon datings allows us to refer the erection of the stronghold to the second half/late 10th century. The results of several years’ interdisciplinary research (2012-2020) introduce qualitatively new data to the issue of the Cherven’ Towns, which both change current considerations and confirm the extraordinary research potential in the archeology of the discussed region.
To smooth or not to smooth? A traceological and experimental approach to surface processing of Bronze and Iron Age ceramics
Authors: Gawron-Szymczyk Aleksandra , Łaciak Dagmara , Baron Justyna
Published: December 2020

The biographic approach – that is, tracing artefacts’ ‘lives’ from production, through their use, and finally to their deposition – is commonly applied in the analysis of lithic, flint, and metal artefacts. Objects made of clay, although the most common artifacts at many prehistoric sites, are rarely subject to such studies. In this paper, we focused on the short span of time during the “life” of a ceramic object when its surfaces were smoothed or/and burnished. Both are typical properties of Bronze/early Iron Age pottery found in today’s Poland. We studied two factors that influenced the desired final effect: the vessel drying time and the applied tool(s). To accomplish this study, we combined the results of observations of 46 samples from three settlements and two cemeteries in southwestern Poland, as well as the analysis of experimental reference samples. We demonstrated that the drying time was crucial, while the tool kit was composed of rather simple, mostly unprepared, objects such as pebbles or pieces of antler. In the smoothing process, we also observed a connection between surface selection (internal/external) and the purpose to which the vessel was put (settlement/funerary).

A field experiment was conducted at Research Farm of Agricultural Research Station, Ummedganj, Kota (Agriculture University, Kota), Rajasthan, India during kharif 2019 to find out the most effective herbicide combination for limiting the menace of weeds in maize. Results showed that density of monocot weeds were observed more than dicot weeds during the experimentation. The prominent weeds were Echinochloa colona, Cyperus rotundus, Digera arvensis, Amaranthus viridis, Acalypha indica and Trianthema portulacastrum etc. caused about 58.3% reduction in grain yield as over two hand weeding at 20 and 40 DAS. In general, grassy weeds were better controlled by herbicides than broad leaves weeds. Among herbicides, maximum weed control efficiency (72.18%) was achieved with application of atrazine 500 g a.i. ha-1 (PE) followed by topramezone 25.2 g a.i. ha-1 at 20-25 DAS (72.18%) which is very close to two hand weeding at 20 and 40 DAS. Furthermore, this treatment also produced higher grain (3496 kg ha-1) and stover yield (6460 kg ha-1) which was at par with atrazine 500 g a.i. ha-1 (PE) followed by tembotrione 120.75 g a.i. ha-1 (20-25 DAS) and atrazine 500 g a.i. ha-1 (PE)+hand weeding 30 DAS with in-situ weeds mulching. Thus, pre-emergence application of atrazine 500 g a.i. ha-1 (PE) followed by topramezone 25.2 g a.i. ha-1 at 20-25 DAS is recommended for better weed control and yield of maize.

As a first step in assessing the viability of periphyton-based shrimp production in lined pond aquaculture systems, the effects of natural substrates (split bamboo poles and coconut coir) on development of periphyton were evaluated. Experiments were conducted in outdoor earthen lined pond to study periphyton biomass on two types of natural substrates such as split bamboo pole and coconut coir which was placed inside the earthen lined pond filled with seawater for duration of 45 days. The periphyton biomass was recorded at 0–40 cm depth, 40–80 cm depth and 80–120 cm for all the substrates. The periphyton biomass, in terms of dry matter (DM) from coconut coir was comparatively higher (3.4995±0.3120 mg cm-2) than the split bamboo poles (3.2011±0.3044 mg cm-2) during the experiment. ‘T’ test has affirmed that significant difference (p<0.05) was observed in the dry matter content of the periphyton among the substrates. ‘T’ test analysis of the data relating to periphyton biomass for split bamboo pole and coconut coir recorded at different depths indicated that upper 0–40 cm depth had higher values than the other depths. Furthermore, among the two substrates, coconut coir (3.4995±0.31201 mg cm-2) was observed to be a better substrate than the split bamboo pole for periphyton biomass production. Coconut coir substrate can be utilised by fin and shellfishes as natural food.

Calculation of stable and unstable periodic orbits in a chopper-fed DC drive
Authors:   Hetman Petro Sahaidachnyi National Army Academy, Kuznyetsov O. O.
Published: December 2020

It is well known that electric drives demonstrate various nonlinear phenomena. In particular, a chopper-fed analog DC drive system is characterized by the route to chaotic behavior though period-doubling cascade. Besides, the considered system demonstrates coexistence of several stable periodic modes within the stability boundaries of the main period-1 orbit. We discover the evolution of several periodic orbits utilizing the semi-analytical method based on the Filippov theory for the stability analysis of periodic orbits. We analyze, in particular, stable and unstable period-1, 2, 3 and 4 orbits, as well as independent on stability they are significant for the organization of phase space. We demonstrate, in particular, that the unstable periodic orbits undergo border collision bifurcations; those occur according to several scenarios related to the interaction of different orbits of the same period, including persistence border collision, when a periodic orbit is changed by a different orbit of the same period, and birth or disappearance of a couple of orbits of the same period characterized by different topology.

Carta de susceptibilidade erosiva da Bacia Hidrográfica do Córrego Curral de Arame, Dourados/MS
Authors: Oliveira Diodato Jonailce , De Oliveira Ribeiro Vinícius
Published: December 2020

Erosão hídrica é um processo natural que é intensificado pela falta de práticas conservacionistas, e retirada da cobertura vegetal do solo.  Tem como consequência, o empobrecimento do solo, assoreamento e eutrofização dos corpos d’água, entre outros. É de fundamental importância tomar conhecimento dos processos erosivos para que os tomadores de decisão adotem medidas de mitigação e/ ou prevenção deste fenômeno. Neste contexto a EUPS entra como ferramenta para estimar a perda de solo por erosão laminar. O uso de sistemas de informações Geográficas (SIG) tem se mostrado bastante eficientes para caracterizar a susceptibilidade erosiva, devido a facilidade de obtenção de dados, conferindo agilidade aos processos. Muitos destes são disponibilizados gratuitamente, como o QGIS, utilizado na metodologia deste projeto. Este trabalho teve como objetivo mapear e analisar qualitativamente a susceptibilidade erosiva da Bacia Hidrográfica do córrego Curral de Arame utilizando Sistema de Informação Geográfica, livre e gratuita. Os valores para a estimativa da perda anual de solo, variaram entre 0 e 389 toneladas por hectare ao ano. Observou-se que o fator que apresenta maior influência sobre os valores de estimativa das perdas de solo para a Bacia Hidrográfica em estudo, foi o fator CP- Uso e Manejo e Práticas Conservacionistas.
Penyebaran Fikih Mazhab Syafi'i di Nusantara: Studi Sosio-Historis Masa Kesultanan Palembang Darussalam
Authors: Adil Muhammad , Harun Muhamad
Published: December 2020

This study explains the spread of the Syafi'i school of fiqh in the Indonesian Archipelago by taking the time of the Palembang Darussalam Sultanate. The dissemination of the Syafi'i school of fiqh was officially carried out through the sultanate institution by the ulama appointed by the Sultan. The official positions in the field of religion are Pangeran Penghulu Nata Agama, Penghulu Nata Agama, and Khatib Imam. This position continued during the colonial period and ended until 1905 as Hoofd Penghulu. In addition, the dissemination of the Syafi'i school of fiqh was also carried out by scholars who had close ties to the sultanate, such as Abdul Samad al-Palimbani, Kemas Fakhruddin, and Syihabuddin al-Misri al-Jawi al-Palimbani. Authentic evidence of the spread of the Shafi'i School of jurisprudence occurred through the translation and copying movement of the Shafi'i School of Islamic scholars, as was done by Sheikh Abdul Samad who wrote and translated books written by Imam Ghazali in the fields of fiqh and Sufism, such as books of BidÄyat al-HidÄyah was translated as HidÄyat al-SÄlikÄ«n fÄ« Suluk al-Maslak al-MuttaqÄ«n, and IhyÄ 'UlÅ«m al-DÄ«n was translated as Sayr al-SÄlikÄ«n ilÄ IbÄdat Rabb al-AlamÄ«n. Thus, it can be seen that this model of dissemination has caused the Syafi'i school of jurisprudence to continue to experience its development until now to dominate as a school of law adopted by the community.
Literasi Politik Komunitas Samin di Bojonegoro dalam Pemilu Perspektif Fiqih Siyasah
Authors: Hasyim Muh Fathoni
Published: December 2020

The dynamics of political participation of the Samin community in Bojonegoro show significant development of political literacy. This study is focused on answering the political literacy of the Samin community in voicing their aspirations in the General Election from the perspective of Fiqh Siyasah. The results of the study show that the level of political literacy of the Samin community is increasing. The indicator is that the enthusiasm of the Samin people in exercising their voting rights in the general election. In facing elections, the Samin community usually holds a community meeting led by the customary head, to determine the direction of their political aspirations. Over time, this tradition, although still valid, the results of its decisions are not binding. This means that the Samin people are given the freedom to make their own choices. This is different from previous times where the results of the deliberations were a collective decision in determining political aspirations. In the context of Fiqh Siyasah, the political literacy of the Samin community in the General Election is an exciting process of democratization, because the participation of the Samin community shows a growing awareness of living as a nation and a state within the frame of diversity. The practice of deliberation carried out by the Samin community is the application of the principle of deliberation in Islam, so that even though the results are not binding, the decision-making process creates a dialogue between community members to build an increasingly dynamic and progressive political literacy of the Samin community.
Organizational and economic prerequisites for integration of business structures into fishing industry of Russian Federation
Authors: Michurina Olga Yurievna , Dubinina Nataliya Aleksandrovna
Published: December 2020

The article focuses on the importance of the Russian fisheries sector as a strategically important industry for the country and a guarantor of Russia's food security. Integration processes that permeate the Russian economy inevitably involve fisheries enterprises in soft and hard integration relationships, forming business associations in various organizational and legal forms. By engaging with each other, the fishing industry enterprises, and after them the country's economy as a whole, get a number of advantages and the positive potential for further development. To build a system of prerequisites for the integration of business structures into the fishing industry of the Russian Federation, there has been carried out the study of historical factors and events of the state regulation of the industry. It has been stated that throughout the history of the Russian fisheries sector, its competitiveness has been ensured by the state support measures. Evidence for this can be found in studying the periods of industry collapse and recovery in post-communist Russia. As a result of systematic measures taken by the state in the field of legislation and institutional decisions, the Russian fisheries sector has undergone some positive changes over the past decades: reducing corruption, restoring positive dynamics in all areas of industry development, increasing investment potential, and increasing catch volumes. There have been identified the historical and institutional prerequisites for the integration of business structures in the fishing industry of modern Russia. The developed system of prerequisites will become the basis for further research in terms of substantiating promising forms of business associations, the implementation of which can have a positive impact on the country and world competitiveness of the Russian fisheries sector

Published: December 2020

This paper is devoted to the study of the role international sporting events in forming image of state. The goal of research is to study the role of the FIFA World Cup in forming Russia’s image. The front-end content analysis is used, which is focused on drawing up the most detailed idea of the information Vow over a certain period in order to identify meaningful dynamics and is of an applied nature. The physical unit of content analysis was the article number (release date), and the text publication was the unit of analysis. Texts for processing were searched in English using a Google search for the period from May 1, 2018 to August 1, 2018. Ne articles should simultaneously contain the words “Russia” and “World cup”. In a generalized form, the search query looked like this: site: [publication site] Russia and World cup. Ne sample population includes the most popular Google search queries. Articles containing only a summary of sports indicators were excluded from the texts found, since the research objectives were satisfied with articles affecting the social, political and economic aspects of the 2018 World Cup. The information priorities of different foreign media are different. For the American and British media, it is important, in particular, to respect human rights in Russia, and for the Chinese media, the opportunity to profit from the supply of our own products. However, after the end of the 2018 FIFA World Cup, negative rhetoric gave way to positive. Ne results of the study indicate the positive role of the 2018 World Cup in shaping the image of the Russian state.

A bail-out intervention: low-speed rotablation for management of an underexpanded stent causing recurrent stent restenosis
Authors: Goktekin Omer , kilic Ismail Dogu , Karagoz Ahmet
Published: December 2020

Background:

Rotablation is used in heavily calcified lesions when balloon angioplasty fails to expand the lesion before stenting.

Case Presentation:

A 68-year-old male patient was admited with angina 9 months after implantation of a 3.5 × 23 mm drugeluting stent in the crux of right coronary artery. Intravascular ultrasound revealed that the strut-to-strut diameter of the stent in the underexpanded region was 1.6 mm. High-pressure balloon inflation up to 26 atm was performed many times and the procedure was again completed with 3.0 and 3.5 mm kissing balloon inflation at 22 atm. After 4 months following the second procedure, the patient was admitted with the same symptoms. This time a 1.75 mm rotablator was used cautiously under low speed (150,000 rpm) to ablate the stent struts which handicap adequate expansion and lead to recurrent stenosis.

Conclusion:

Rotablation can also be used to fix an underexpanded stent if the other options fail.
The Urgency of the Prohibition of Cosmetics on the Marine Environment in Marine Tourism
Authors: Monifa Andre
Published: December 2020

The advancement of marine tourism has a positive impact on local communities and also raises concerns about negative effects on coral reefs. Damage to coral reefs in Indonesia currently reaches 46 percent. The damage turns coral reefs white and threatens biodiversity and the function of coral reef ecosystems. One of the causes of damage is the oxybenzone and octinoxate content in sunscreens used by marine tourists. Hawaii has issued a law banning sunscreen lotions containing these substances. The purpose of this study was to analyze the urgency of banning sunscreens in marine tourism areas in Indonesia as a basis for drafting regulations to protect coral reef ecosystems. This study uses a jurisdictional normative approach and analyzes secondary data such as legal theory, laws and regulations, and is supported by several studies on coral reefs. The results of this study indicate that sunscreen can protect the skin from exposure to ultraviolet rays which can cause acute and chronic health problems. However, the use of oxybenzone and octinoxate as chemical filters also has the potential to cause health problems. These substances also cause coral bleaching even at the lowest settlement level. The use of sunscreen is regulated in several parts of the world. Referring to the progressive legal theory, the prohibition of using sunscreens containing oxybenzone and octinoxate in marine tourism areas is considered urgent because the form of the law is made for human welfare and it is a solution to the absence of laws regarding the protection of coral reefs in Indonesia. Adapt selective and responsible law based on facts and environmental data in accordance with responsive legal theory.

Este articulo tiene como objeto de estudio el análisis de las clases de tecnología e informática utilizando una plataforma tecnológica y si estas se encuentran alineadas con el modelo pedagógico que persigue la institución educativa. Esta investigación se realizó en la Institución Educativa Distrital Reuven Feuerstein de la ciudad de Barranquilla-Colombia, igualmente se deriva de la tesis doctoral realizada por el autor de este artículo. Algunos docentes en nuestro contexto no tienen en claro la didáctica y estrategias metodológicas que se deben utilizar durante las clases teniendo en cuenta el modelo pedagógico y aún más utilizando herramientas tecnológicas, se realizan una serie de encuestas y entrevistas a cada una de las partes involucradas en la problemática como lo son docentes y estudiantes para indagar si existe concordancia entre lo que dice el PEI (Proyecto Educativo Institucional) y lo que se realiza en la práctica docente. Se tuvo en cuenta un enfoque tanto cualitativo como cuantitativo, para la recolección de la información, basado principalmente en encuestas, entrevistas, análisis documental y la observación, donde se obtienen los datos genéricos que enmarcan esta investigación. En este estudio recurrimos al método de triangulación que permite reconciliar datos de tipo cuantitativo y cualitativo. Esta reconciliación significa, para nosotros, complementar los datos derivados de las distintas fuentes. La población seleccionada para la presente investigación pertenece a los grados decimo y undécimo en total 131 estudiantes, para una muestra de 98 estudiantes. Los resultados de las encuestas arrojan que los estudiantes tienen una percepción de que la enseñanza que reciben es de corte constructivista mientras que el docente basada en el modelo crítico.

In 2017–2019 we conducted researches in NPO “Triumph”, Matveevo-Kurgansky district, Rostov region, and in fields of V.S. Pustovoit All-Russian Research Institute of Oil Crops, Krasnodar. The purpose of the research was to develop methodic questions of selection of self-fertile biotypes during production of foundation seeds of confectionary sunflower varieties. We stated self-sterile and semisterile consist the main part of the studied seven OPvarieties and are equal 68.5% in average. They vary from 60.3% in the Enisey variety to 75.0% in Dobrynya. Basing on our researches we proposed a rating scale for self-fertility level in sunflower varieties and a scheme of foundation seeds growing oriented for selection of biotypes with increased selffertility. We developed a promising varietypopulation Dobrynya+, its average self-fertility of plants is equal to 12.2% comparing to 6.5% of the initial variety. A share of the less valuable self-sterile biotypes in it decreased from 22.2 to 12.0%, and a portion of the most valuable highly self-fertile, contrariwise, increased from 13.9 to 18.0%. By a complex of the other economically valuable traits a population Dobrynya+ does not differ of the initial variety.

Background:

Due to its rarity, surgical treatments for a complete fifth lumbar osteoporotic vertebral burst fracture (L5 OVBF) have yet to be well documented as compared to that for osteoporotic vertebral fractures of the thoracolumbar spine. The current case report discusses details of the surgical outcomes following posterior decompression and fusion for a complete L5 OVBF.

Case Description:

Three women, ranging in age from 69 years to 82 years, were surgically treated for a complete L5 OVBF. Two of these patients were being treated for rheumatoid arthritis. Surgery was performed using the L5 shortening osteotomy or vertebroplasty, with one- or two-level posterior lumbar interbody fusion, and posterior spinal fixation for the L2 or L3 to the pelvis. Although the spinal alignment parameters, which included lumbar lordosis (LL), pelvic incidence-lumbar lordosis, T1 pelvic angle, and sagittal vertical axis, were better as compared to that observed before the surgery, these worsened at the final follow-up due to clinical fractures that occurred at the adjacent vertebral body and proximal junctional kyphosis. Compared to preoperative Japanese Orthopaedic Association (JOA) scores, postoperative JOA scores were improved and maintained at the final follow-up.

Conclusion:

Posterior surgery of a complete L5 OVBF led to improvement of both the JOA score and spinal alignment after the surgery. Despite a worsening of the spinal alignment parameters, the JOA score was maintained at the final follow-up.

Personal protective equipment (PPE) has been highly recommended by the U.S. Centers for Disease Control and Prevention (CDC) for self-protection under the disastrous SARS-CoV-2 (COVID-19) pandemic. Nevertheless, the massive utilization of PPE, especially the N95 respirators and sing-use masks, encounters significant challenges in recycling and sterilizing the used masks. To tackle the environmental pollution of currently used masks made of synthetic plastic, in this work, we designed a reusable, biodegradable, and antibacterial mask. The mask was prepared by electrospinning of polyvinyl alcohol (PVA), poly(ethylene oxide) (PEO), and cellulose nanofiber (CNF), and with subsequent esterification and then deposition of nitrogen-doped TiO2 (N-TiO2). The fabricated mask containing photocatalytic N-TiO2 can reach ~100% sterilization under light source (200-2500 nm, 106 Wm-2) as 0.1 sun simulation for only 10 min. Thus, the used mask can be rejuvenated through light irradiation and reused, which represents one of the handiest technologies for handling used masks. Furthermore, the intermolecular interactions between PVA, PEO and CNF enhanced electrospinnability and the mechanical performance of the resultant mask. The obtained masks possess superior mechanical strength (10-fold elastic modulus and 2-fold tensile strength higher than a commercial single use mask). The comprised electrospun nanofibers with porous structures in between as well as strong electrostatic attraction enabled breathability (83.4 L min-1 of air flow rate) and superior particle filterability (98.7 %). Therefore, this novel mask could be a great alternative to current masks to addressing the urgent need for sustainable, reusable, environmentally friendly, and efficient personal protection designs under the ongoing COVID-19 contagion.
Computational Analysis of the Effect of [Tea][Ms] and [Tea][H2PO4] Ionic Liquids on the Structure and Stability of Aβ(17-42) Amyloid Protofibrils

Published: December 2020

Experimental studies have reported the possibility of affecting the growth/dissolution of amyloid fibres by the addition of organic salts of the room-temperature ionic-liquids family, raising the tantalizing prospect of controlling these processes at physiological conditions. The effect of [Tea][Ms] and [Tea][H2PO4] at various concentrations on the structure and stability of a simple model of Aβ42 fibrils has been investigated by computational means. Free energy computations show that both [Tea][Ms] and [Tea][H2PO4] decrease the stability of fibrils with respect to isolated peptides in solution, and the effect is significantly stronger for [Tea][Ms]. The secondary structure of fibrils is not much affected, but single peptides in solution show a marked decr

ease in their $\beta$-strand character, and an increase in

$\alpha$-propensity, again especially for [Tea][Ms]. These observations, consistent with the experimental picture, can be traced to two primary effects, i.e., the different ionicity of the [Tea][Ms] and [Tea][H2PO4] water solutions, and the remarkable affinity of peptides for [Ms]^- anions, due to a multiplicity of H-bonds.
Small Molecules to Destabilize the ACE2-RBD Complex: A Molecular Dynamics Study for Potential COVID-19 Therapeutics

Published: December 2020

The ongoing COVID-19 pandemic has infected millions of people, claimed hundreds of thousands of lives, and made a worldwide health emergency. Understanding the SARS-CoV-2 mechanism of infection is crucial in the development of potential therapeutics and vaccines. The infection process is triggered by direct binding of the SARS-CoV-2 receptor-binding domain (RBD) to the host cell receptor, Angiotensin-converting enzyme 2 (ACE2). Many efforts have been made to design or repurpose therapeutics to deactivate RBD or ACE2 and prevent the initial binding. In addition to direct inhibition strategies, small chemical compounds might be able to interfere and destabilize the meta-stable, pre-fusion complex of ACE2-RBD. This approach can be employed to prevent the further progress of virus infection at its early stages. In this study, Molecular docking is employed to analyze the binding of two chemical compounds, SSAA09E2 and Nilotinib, with the druggable pocket of the ACE2-RBD complex. The structural changes as a result of the interference with the ACE2-RBD complex are analyzed by molecular dynamics simulations. Results show that both Nilotinib and SSAA09E2 can induce significant conformational changes in the ACE2-RBD complex, intervene with the hydrogen bonds, and influence the flexibility of proteins. Moreover, essential dynamics analysis suggests that the presence of small molecules can trigger large-scale conformational changes that may destabilize the ACE2-RBD complex.
Ionic Charge Manipulation Using Solution and Gas-Phase Chemistry to Facilitate Analysis of Highly Heterogeneous Protein Complexes in Native Mass Spectrometry

Published: December 2020

Ionic signal in native MS typically populates high m/z regions of mass spectra, which frequently extend beyond the precursor ion isolation limits of most commercial mass spectrometers. An approach explored in this work relies on adding supercharging reagents to protein solutions as a means of increasing the extent of multiple charging of non-covalent complexes in ESI MS without compromising their integrity. This shifts the ionic signal down the m/z scale to the region where ion selection and isolation can be readily accomplished, followed by limited charge reduction of the isolated ionic population. The feasibility of the new approach is demonstrated using non-covalent complexes formed by hemoglobin with structurally heterogeneous haptoglobin.
