Long-Term Care of the Pediatric Kidney Transplant Recipient
Authors: Fernandez Hilda E. , Foster Bethany J.
Published: May 2021

Pediatric kidney transplant recipients are distinguished from adult recipients by the need for many decades of graft function, the potential effect of CKD on neurodevelopment, and the changing immune environment of a developing human. The entire life of an individual who receives a transplant as a child is colored by their status as a transplant recipient. Not only must these young recipients negotiate all of the usual challenges of emerging adulthood (transition from school to work, romantic relationships, achieving independence from parents), but they must learn to manage a life-threatening medical condition independently. Regardless of the age at transplantation, graft failure rates are higher during adolescence and young adulthood than at any other age. All pediatric transplant recipients must pass through this high-risk period. Factors contributing to the high graft failure rates in this period include poor adherence to treatment, potentially exacerbated by the transfer of care from pediatric- to adult-oriented care providers, and perhaps an increased potency of the immune response. We describe the characteristics of pediatric kidney transplant recipients, particularly those factors that may influence their care throughout their lives. We also discuss the risks associated with the transition from pediatric- to adult-oriented care and provide some suggestions to optimize the transition to adult-oriented transplant care and long-term outcomes.

Published: May 2021

Se efectuaron análisis químicos y petrográficos de tres muestras de los productos de la erupción del volcán "El Chichón" (marzo-abril 1982). Los análisis químicos muestran que se trata de magma de composición andesítica con un alto contenido de gases. El análisis petrográfico reveló la presencia de anhidrita en dos de las muestras, lo cual es interpretado como resultado de la contaminación con aguas sulfurosas y evaporitas observadas en la zona. Los resultados obtenidos pueden indicar la existencia de una cámara magmática muy superficial. Con base en los análisis de componentes solubles en agua, se calculó la masa total de estos en aproximadamente 31.8 x 106 Ton, para una masa total de los productos de 0.5 km3.

En este trabajo se estudian la composición isotópica y la concentración de gases inertes en muestras de fluidos hidrotérmicos de ocho áreas de descarga en la Republica Mexicana. Se ha encontrado que Xe, Dr y una gran proporción de Ar y Ne son de composición isotópica atmósferica. Una pequeña fracción de Ar es de origen radiogénico. Todos los sistemas hidrotérmicos mexicanos bajo estudio contienen helio del manto (de 4 a 44% del helio total). Los valores de la razón 3He/4He varían a lo largo y a través del Eje Volcánico Transmexicano, y son congruentes con el patrón geoestructural así como también con las características petroquímicas de los productos volcánicos del Plioceno tardio - Cuaternario. La porción máxima del helio del manto es característica de los sistemas hidrotérmicos mas calientes (Los Azufres y Cerro Prieto} y de los alrededores de la caldera de Los Humeros (manantialesde Quateloluco). Se observa un contenido anormalmente alto de Ne en las mismas áreas. Teniendo en mente las peculiaridades análogas de otros importantes sistemas hidrotérmicos del mundo, estas evidencias sugieren un alto potencial geotérmico para esas áreas.
Método para hallar la anelasticidad en zonas con poco recubrimiento sismográfico. Aplicación a la zona del Atlántico norte que comprende la Cordillera de Knipovitch
Authors: Canas J. A.
Published: May 2021

Del estudio de las características de diversos sismogramas sintéticos se obtiene la atenuación anelástica en una región situada en el norte del océano Atlántico. Los resultados obtenidos indican que a la región situada entre Spitsbergen y la estación sismográfica KTG, en Groenlandia, le corresponden modelos similares de velocidades de ondas de cizalla y atenuación anelástica que los correspondientes a la región >23 m.a. del océano Atlántico. Suponiendo que la atenuación debajo de la Cordillera de Knipovitch es la misma que la correspondiente a la Cordillera Central del océano Atlántico, se obtiene que la anchura de la zona de bajos valores de Q es del orden de 174 ± 37 km.
Estudio del enjambre de San Quintin, Baja California, México, ocurrido durante 1975
Authors: Rebollar C. J. , Reyes A. , Reichle M.
Published: May 2021

Las localizaciones epicentrales de los eventos del enjambre de San Quintin se encuentran confinadas en una área epicentral relativamente pequeña, 8±1 km de radio, a profundidades de 15 y 20 km, no mostrando ninguna tendencia bien definida ni variaciones apreciables en los epicentros durante el tiempo de observación con estaciones portatiles (diez meses). Existe la posibilidad de una falla a lo largo de la costa desde donde se localizó el enjambre, hasta San Antonio del Mar. El rumbo de esta posible falla está en la dirección Noreste, y concuerda con una de las direcciones del plano de falla que es Norte 40ºOeste. Desafortunadamente, debido a la localización submarina de la actividad sísmica, no es posible confirmar con una inspección geológica la traza de falla. El momento sísmico del evento principal, magnitud local 5.2 (Ms= 4.7), fue calculado comparando las amplitudes de sismogramas sintéticos y reales. Este momento sísmico fue de 1.53 ± 2 x 1024 dinas-cm. El momento sísmico cumulativo calculado para todos los eventos registrados durante 1975, con magnitudes entre 3.0 y 5.2, fue de 3.68 x 1024 dinas-cm, que es equivalente a un evento de magnitud local de 5.4. El desplazamiento promedio en función del momento sísmico acumulativo fue de 5.7 ± 1.4 cm/año. La caída de esfuerzos del evento principal suponiendo una falla circular fue de 2.2 ± 1. 7 bares. El valor de b asociado al enjambre fue de 1.06. Para el cálculo del momento sísmico de 112 eventos registrados en Río Hardy se usó la relación empírica de magnitud local ML y el momento sísmico M0 dado por logM0 = 1.64 ML + 15 .6, que es similar al calculado por Bruney Wyss (1968).doi: https://doi.org/10.22201/igeof.00167169p.1982.21.4.871

Authors: Salazar S. , Bravo J. L.
Published: May 2021

De enero a marzo y de mayo a julio de 1979 se recolectaron muestras de aerosol atmosférico a bordo del B/0 "Mariano Matamoros" en el Noreste del Océano Pacífico Ecuatorial (7° N, 84°W). Se determinaron los principales cationes solubles en agua, potasio, calcio y magnesio, con el f'm de evaluar los enriquecimientos de estos elementos con respecto al sodio. Los resultados obtenidos muestran que las distribuciones de los cationes son representadas por curvas log-normales.Los factores de enriquecimiento promedio, obtenidos a partir de las razones de las concentraciones K:Na, Ca:Na, fueron mayores que el lOO% y para el Mg:Na no fue significativamente distinto de cero, siendo su única fuente de aportación las sales del mar. Usando la regresión de variable múltiple, se obtuvo que para el K y Ca existe contribución del aerosol de origen continental y del aerosol de fondo. En caso de existir fraccionamiento iónico éste es de poca influencia en el factor de enriquecimiento aquí detectado.

Authors: Jauregui O. E.
Published: May 2021

Se examinan las variaciones de largo periodo de la visibilidad horizontal en dirección del centro de la Ciudad de México.La transparencia del aire se ha deteriorado en general, en el periodo 1937-75, sin embargo, en la segunda mitad de los años setenta, se observa un incremento en la visibilidad promedio. Este aumento se debe a una disminución de la frecuencia de visibilidades malas (menores de 1 km) y a una mayor frecuencia de visibilidades regulares (de 2 a 10 km). Este cambio coincide en general con el tiempo a partir del cual las autoridades sanitarias de la ciudad comenzaron a tomar medidas para controlar y reducir las emisiones de contaminantes del aire.

Published: May 2021

The 2020 U.S presidential election came with the result of Joe Biden’s victory. This research is aimed at investigating Biden’s ideology manifested in his inaugural speech which was delivered on January 20, 2021. The analysis in this research was conducted under the theory of Critical Discourse Analysis (CDA). In finding the ideology, the researcher worked on the microstructure level by studying the presupposition as proposed by Dijk. The result of this research shows that there are three types of presupposition present in Biden’s inaugural speech i.e. lexical, existential, and factive in which lexical presupposition appear to be the most frequent one. The analysis of the presupposition also result to the finding of Biden’s ideology manifestation towards the issue of immigrants, healthcare, racism, democracy, and climate change.

Published: May 2021

Objetivamos compreender a construção do percurso gerativo de sentido na publicidade audiovisual #VelhaPra da linha Chronos, com base em uma análise empírica da terceira geração semiótica (VERÓN, 2004). A análise possibilitou visualizar como os modos semióticos foram utilizados na produção de significados, a buscar ressignificar o sentido da velhice com base em uma narrativa contrária aos padrões consolidados para este segmento, apresentando transformações significativas na produção simbólica, através da experiência das personagens, em um processo de vivência do envelhecimento sem as perdas de capital. Contudo, apesar das contribuições narrativas para uma mudança do imaginário social acerca das ‘novas velhas’ e o seu empoderamento, podem ainda, reforçar aspectos relacionados a um envelhecimento bem sucedido, maximizando um sentimento de não-pertencimento daquelas que não seguem as performances das personagens, uma vez que é reiterado o valor social de uma velhice jovial e ativa.
Global Finite-Time Stabilization Problem of Affine Nonlinear Systems with Unknown Functions
Authors: Jia Fujin , Lu Junwei , Li Yong-Min , Li Fangyuan
Published: May 2021

In this paper, the global finite-time stabilization (FTS) of nonlinear
systems with unknown functions (UFs) is studied. Firstly, in order to
deal with UFs, a Lemma is proposed to avoid the Assumptions of UFs.
Secondly, based on this Lemma, the control algorithm designed by using
backstepping has no partial derivative of virtual controllers, so it
avoids the “differential explosion” problem of backstepping. Thirdly,
by using Lyapunov analysis method, backstepping and FTS method, a global
FTS control algorithm of nonlinear systems with UFs is proposed.
Finally, the feasibility of developed control approach is illustrated by
the simulation results of a manipulator.

Authors: Yakubu Danlami , Oladele Oladimeji
Published: May 2021

Rice productivity and sustainability are threatened by both biotic and abiotic stresses, the effects of which can be further aggravated by dramatic changes in global climate. The most viable option for rice farmers is to use climate change adaptation practices. This study therefore investigated the determinants of use of climate change adaptation practices among rice farmers in Kebbi State, North-West, Nigeria. Data were collected from a sample of 279 farmers selected using a multistage sampling procedure. The results of the data analysis revealed that the farmers used improved rice varieties, intercropping, recommended rates of fertilizers and other chemicals as climate change adaptation practices among others. Education, climate change awareness, and extension contact significantly influenced the use of climate change adaptation practices among the farmers. Other determinants of use of climate change adaptation practices among the farmers were years of cooperative membership, affordability, farming experience, weather information and farm size. It was concluded that use of climate change adaptation practices was determined by socioeconomic, institutional and technological characteristics. It is recommended among others that government policy should be geared towards encouraging the farmers especially the younger ones to acquire more formal education, larger farmlands and more climate change awareness.

The purpose of the current study is to examine whether “learning by Zoom” or e-learning was a short-term temporary solution or whether there is a real chance that distance teaching and learning will become a teaching technique in the post-COVID era. What is teachers’ personal preference for e-learning with regard to interpersonal interaction with the students, the benefits of e-learning for students, as well as interest, order, organization, and clarity in teaching. Moreover, the effectiveness of e-teaching was examined from a multicultural perspective – at schools in Israel, the hi-tech state, and in Belarus, where the culture of the book is a major symbol. We explored the perceptions of teachers in Israel and in Belarus on four measures: personal preferences, advantages and disadvantages for teaching and learning, measures of good teaching (interest, order, and organization), and interpersonal interactions between the teacher, the students, and the faculty. E-teaching is not an alternative for traditional education but does generate a new reality that facilitates great improvements and advantages but produces new challenges for the educational system.

Published: May 2021

Chamomile is one of the well-known herbs in the world, with numerous medicinal, cosmetic and health benefits. In this study, a factorial experiment was conducted in a randomized complete block design technique to evaluate the three different dosses of nitrogen (N1 = 0, N2 = 50 and N3 = 100 kg·ha–1) from urea 46%, and three different vermicompost dosses (V1 = 0, V2 = 4 and V3 = 8 t.ha–1) and three different zeolite superabsorbent levels (S1 = 0, S2 = 50 and S3 = 100 kg·ha–1) on flower yield and essential oil of Chamomile in Kazeroon, Fars province in 2017. The results showed that increasing the amount of nitrogen and vermicompost increased the plant height, flower diameter, number of flowers, flower yield, essential oil content, biological yield and essential elements content of the Chamomile. In the interaction of N × V, the highest and lowest dry flower yields were observed in N3V3 (456 kg·ha–1) and N1V1 (316.9 kg·ha–1) treatments, respectively. The interaction showed that the highest and the lowest of essential oil content were observed in N3V3 (2.82 kg·ha–1) and N1V1 (1.56 kg·ha–1), respectively. The highest content of chamazulene compound were obtained in N2V3S3 treatments with 6.40% and the highest content of α-bisabolol oxide A related to N2V3 treatments with 53.50%. Based on the interaction results of N × V × S, the highest biological yield was observed in N3V2S3 with 2012 kg·ha–1. The reason for the results can be due to the high moisture storage capacity of the superabsorbent and vermicompost, which can increase the availability of water consumption. In general, it seems that with increasing nitrogen and vermicompost ratios of soil, not only the nutritional availability of the plant (especially nitrogen, phosphorus and potassium) increased, but also the physical structure and vital processes of the soil by creating a suitable substrate for root growth- increased the production of chamomile flower yields.

Authors: Ouedraogo Frederic B. , Lefebvre Sandra L. , Hansen Charlotte R. , Brorsen B. Wade
Published: May 2021

OBJECTIVE

To determine prevalences of low compassion satisfaction (CS), high burnout (BO), and high secondary traumatic stress (STS) scores among full-time US veterinarians and estimate effects of selected demographic, employment-related, and education-related factors on those scores.

SAMPLE

5,020 full-time veterinarians who participated in the 2016, 2017, and 2018 AVMA Census of Veterinarians surveys.

PROCEDURES

Data were obtained from census surveys regarding demographic, employment-related, and education-related factors, and scores assigned to items from a professional quality-of-life instrument designed to measure CS and compassion fatigue (ie, BO and STS) were compared between and among various demographic and employment groups.

RESULTS

Overall, 35.5% of veterinarians were classified as having low CS scores, 50.2% as having high BO scores, and 58.9% as having high STS scores. Controlling for other variables, high educational debt was associated with low CS, high BO, and high STS scores. Veterinarians who spent ≥ 75% of their time working with dogs or cats had higher BO and STS scores than did those who spent < 25% of their time. Veterinarians with more experience and higher annual incomes had higher CS scores and lower BO and STS scores. Women had higher BO and STS scores than did men, but no gender differences were observed in CS scores.

CONCLUSIONS AND CLINICAL RELEVANCE

Several variables were identified that may put veterinarians at higher risk than others for compassion fatigue and low CS. These findings may be useful in the development of resources and targeted initiatives to support and defend veterinarian well-being.
The Removal of a Fractured Guidewire During Mechanical Thrombectomy. A Case Report
Authors: Filep Rares Cristian , Bloj Andrei Florin , Marginean Lucian
Published: May 2021

Recent randomized controlled trials have transformed the treatment of acute ischemic stroke. Mechanical or aspiration thrombectomy is the main treatment option for occlusions of large intracranial vessels. Despite its high technical success rate, endovascular thrombectomy can sometimes be complicated by anatomical peculiarities or device failures. The most frequent complications are related to vessel dissection or vessel perforation by devices while navigating intricate anatomy. Rarer still are technical device failures, like spontaneous stent-retriever detachment, which occurred with older generation retrievers. This case reports a rare device failure, which, to the best of our knowledge, has not been reported in the literature so far, namely a microwire fracture in the middle cerebral artery. This was successfully removed with an Eric stent-retriever. The potential causes and possible management strategies are discussed.

Published: May 2021

Berbagai macam tumbuhan dapat digunakan sebagai pewarna tekstil. Namun sejak ditemukannya zat warna sintetis pada abad 19, maka produksi tekstil di Indonesia beralih ke zat warna sintetis. Sayangnya dampak yang ditimbulkan dari limbah zat warna sintetis ini mencemari lingkungan hidup manusia. Pelarangan penggunaan pewarna sintetis di Eropa dan Amerika, serta isu global yaitu Back to Nature, merupakan hal yang tidak mungkin dihindari, bahkan harus dilaksanakan secara konsisten dan berkelanjutan. Produk tekstil juga berhadapan dengan tuntutan selera masyarakat masa kini, yaitu kebutuhan  fashion dan interior, serta kebutuhan karya-karya yang dapat memberi kepuasan batin, sehingga diperlukan ciptaan karya baru yang kreatif dan inovatif. Dalam rangka mencari keberagaman dan pengkayaan warna dari tumbuhan yang ada di Indonesia, penulis ingin mengambil tumbuhan Kluwih (Artocarpus camansi) sebagai pewarna alam untuk tekstil dengan teknik celup dan cetak langsung (ecoprint). Metode pustaka, observasi dan eksperimentasi digunakan untuk mengumpulkan data. Metode practice based research digunakan untuk memperoleh pengetahuan baru melalui riset praktek dan hasil riset praktek. Metode eksperimen digunakan untuk mendapatkan ilmu pengetahuan baru terutama pada pewarna alam serta improvisasi jika dalam pelaksanaan menemukan ide-ide baru. Pada terapan warna ini akan dilakukan dengan teknik batik, celup dan ecoprint.

Objetivo: Analisar se existe eficácia na utilização de dessensibilizantes antes do tratamento clareador para a diminuição da sensibilidade dentária. Revisão bibliográfica: Para os pacientes que possuem dentes vitais escurecidos, o clareamento dentário é um dos procedimentos odontológicos mais solicitados pelos pacientes que querem um sorriso mais agradável. Diante do tratamento de clareamento dentário, é de extrema importância ter o conhecimento que devido a penetração do agente clareador nos túbulos dentinários, devido à perda de mineral dental, é onde pode ocorrer a sensibilidade dentinária. A sensibilidade dentinária ocorre devido à desobliteração dos túbulos dentinários, onde ocorre a comunicação do meio externo com o tecido dentinário. Uma das alternativas para controlar ou diminuir a sensibilidade dentária após ou durante um tratamento clareador é a utilização de dessensibilizantes, onde sua principal função dos agentes dessensibilizantes e obliterar os túbulos dentinários.  Considerações finais: A técnica com comprovação de eficácia indicada por estudos clínicos controlados indica o uso de géis dessensibilizantes previamente ao clareamento em consultório.

Objetivo: Identificar se enfermeiros de um hospital no norte do estado do Espírito Santo possuem conhecimento técnico/científico do suporte avançado de vida sobre a Parada Cardiorrespiratória (PCR) no adulto, baseado nas novas diretrizes da American Heart Association (AHA) de 2018. Métodos: Estudo de campo com abordagem quantitativa voltada para enfermeiros, elaborado com base nas diretrizes da AHA 2018, com questões objetivas semiestruturadas referentes ao conhecimento técnico científico do Suporte Avançado de Vida (SAV) sobre a PCR no adulto. Resultados: Participaram da pesquisa 30 enfermeiros, desses, 66.67% responderam que fizeram curso teórico prático de Advanced Cardiovascular Life Support (ACLS) após a faculdade. Quanto ao reconhecimento dos sinais de PCR, nenhum enfermeiro respondeu de forma correta e 73.33% não sabem qual atitude imediata a ser tomada após o reconhecimento da PCR, mostrando desconhecimento das diretrizes da AHA. Conclusão: O estudo apontou a necessidade de treinamento regular dos profissionais entrevistados, pois a falta de especialização somada ao desconhecimento das diretrizes da AHA contribuiu para um conhecimento abaixo do desejado, resultando em um baixo percentual de respostas corretas no que tange aos conhecimentos da PCR no ACLS adulto.

MicroRNAs (miRNA, miR) - regulate gene expression, take part in the regulation of cell life, proliferation and apoptosis. There are not enough publications on the study of microRNA in the plasma of patients with choroidal melanoma (CM) and the presented data are contradictory. An increase in the level of microRNA-146a in blood plasma was noted in patients with cancer of the lung, esophagus and breast. In the present study, we used microRNA-146a in the blood plasma of patients with CM. Purpose. To determine the possibility and reliability of detecting microRNA-146a in the blood plasma of patients with CM, taking into account the localization of the tumor and its size. Material and methods. The blood plasma of 84 patients was studied mean age 63.4±1.2 years. A control group of 28 people who did not have tumor or chronic autoimmune diseases mean age 63.25±1.43 years. The expression level of miRNA-146a was determined by quantitative PCR. Results. An increase in the level of microRNA-146a was shown, which correlates with the localization and thickness of the tumor. The results were confirmed by statistical analysis. Conclusion. MicroRNA-146a, which increases in plasma levels in patients with CM as its size increases, can be used as a biomarker of aggressive tumor course in terms of hematogenous metastasis. Key words: choroidal melanoma, microRNA-146a, biomarkers.

The leading direction in the study of the so-called non-motor manifestations of Parkinson's disease (PD) is associated with the assessment of structural and functional changes in the organ of vision. Proceeding from the neurodegenerative nature of the disease, on the one hand, and the possibility of an objective in vivo assessment of both functional and structural changes in the corneal nerve fibers (NVR), on the other hand, the assessment of the state of thin myelin-free NVR in PD seems promising. Purpose of the study. Analysis of changes in the course and structure of NVR in the early stages of PD based on an objective algorithm of in vivo confocal microscopy (IVCM). Material and methods. The study was conducted in a group of 26 patients aged 39 to 69 years with a verified diagnosis of Parkinson's disease. In addition to the standard neurological and ophthalmological examination, all patients underwent IVCM using an HRT III device with a special corneal attachment Cornea Rostock, followed by processing of the obtained images using the author's analysis algorithm. Results. A significant decrease in the directional anisotropy coefficient and an increase in the directional symmetry coefficient of the NVR were found (average values 3.15±1.08 and 0.92±0.04, respectively). Normally, in an identical age range, these indicators are 3.5±0.85 and 0.86±0.11, respectively. In addition, qualitative structural changes were also noted, which consisted in an increase in the number of branches from the main nerve trunks, an increase in the tortuosity of the NVR, multidirectionality and "clearness". In 19 cases, the presence of macrophages, Langerhans dendritiform cells, was detected, the presence of which is an indirect sign of the inflammatory process. Conclusion. The preliminary nature of the results obtained in this work and the need for further research in this direction are associated, on the one hand, with a small sample of observations, and, on the other hand, with the use, due to the need, due to the lack of initial data, of the condition assessment criterion not based on a comparative analysis with conditionally normal age indicators. In the future, in order to address the issue of the specificity of changes in NVR and the possibility of using these changes as a marker of PD progression, dynamic studies are required, which involve the identification of the presence or absence of a correlation between the stage of the disease, the results of known monitoring methods (for example, electromyography) and quantitative indicators of the state of NVR. Key words: Parkinson's disease, corneal nerve fibers, laser confocal microscopy of the cornea.

Willows (Salix), which are found worldwide, have secondary metabolites that are valuable as dietary supplements for animal feed. The objectives of the current study were to test the effects of irrigation source on the production of secondary metabolites and their potential to inhibit nematode exsheathment. Three willow ecotypes (Kishon, Meah Shearim, and Golan) were irrigated with Fresh Tap Water (FW) or Treated Wastewater (TWW). TWW irrigation resulted in a doubling of biomass production compared with FW, probably due to the presence of more nutrients, particularly nitrogen. The type of irrigation water (TWW vs. FW) did not affect the quantity and quality of secondary metabolites, such as phenols, in all three willow ecotypes, although there was a difference in the chemical profile of glycoside phenols between willow ecotypes. Biomass and secondary metabolite production differed greatly between ecotypes, which was evident in the differing concentrations of phenols and flavonoids. These varying concentrations in turned affected the inhibition of the exsheathment of larval L3 nematodes. The ethanol extract of the Kishon ecotype consistently resulted in more than 90% exsheathment inhibition when tested on the L3 larval stage, whereas extracts from Meah Shearim and Golan resulted in lesser inhibition. A sub-fraction of the ethyl acetate fraction obtained from Kishon had maximum activity with more than 90% exsheathment inhibition.

The aggregation of amyloid β (Aβ) peptides is a significant hallmark of Alzheimer’s Disease (AD) and the inhibition and detection of Aβ aggregates are important for the treatment and diagnosis of AD. Herein, a series of benzothiazole-based luminescent Ir(III) complexes HN-1 to HN-8 were reported, which exhibit appreciable Aβ aggregation inhibition ability in vitro and in living cells. In addition, they are capable of inducing a fluorescence turn-on effect when binding to Aβ fibrils and oligomers. Most importantly, compared to previously reported cationic metal complexes, the neutral Ir complexes reported here show optimal Log D values, which suggest these compounds should have enhanced blood brain barrier (BBB) permeability. Most importantly, in vivo studies show that the neutral Ir complexes HN-2, HN-3, and HN-8 successfully penetrate the BBB and stain amyloid plaques in AD mice brains after a 10-day treatment via i.p. injection, which is unprecedented for Ir(III) complexes, and thus can be used as lead compounds for AD therapeutics development.
Discovery of the Class I Antimicrobial Lasso Peptide Arcumycin

Published: May 2021

Lasso peptides are a structurally diverse superfamily ofconformationally-constrained peptide natural products, of which asubset exhibits broad antimicrobial activity. Although advances inbioinformatics have increased our knowledge of strains harboringthe biosynthetic machinery for lasso peptide production, relatingpeptide sequence to bioactivity remains a continuous challenge.Towards this end, a structure-driven genome mining investigationof Actinobacteria-produced antimicrobial lasso peptides wasperformed to correlate predicted primary structure with antibioticactivity. Bioinformatic evaluation revealed eight putative novelclass I lasso peptide sequences. This subset is predicted topossess antibiotic activity as characterized members of this classhave both broad spectrum and potent activity against Gram positivestrains. Fermentation of one of these hits, StreptomycesNRRL F-5639, resulted in the production of a novel class I lassopeptide, arcumycin, named for the Latin word for bow or arch,arcum. Arcumycin exhibited antibiotic activity against Gram positivebacteria including Bacillus subtilis (4 μg/mL),Staphylococcus aureus (8 μg/mL), and Micrococcus luteus (8μg/mL). Arcumycin treatment of B. subtilis liaI-β-gal promoterfusion reporter strain resulted in upregulation of the system liaRSby the promoter liaI, indicating arcumycin interferes with lipid IIbiosynthesis. Cumulatively, the results illustrate the relationshipbetween phylogenetically related lasso peptides and theirbioactivity as validated through the isolation, structuraldetermination, and evaluation of bioactivity of the novel class Iantimicrobial lasso peptide arcumycin.
