Two novel alkyl thiophene-modified pyrene derivatives (1)-(2) were created and synthesized using palladium-catalyzed Stille coupling processes and Friedel-Crafts reaction of pyrene. The polycyclic aromatic groups of the thiophene-modified pyrene were oxidized with Ag[Al(OC(CF3)3)4] to provide the insensitive radical cations 1•+-2•+ based on the alkyl thiophene-modified pyrene derivatives. Nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR), UV-Vis spectroscopy, and density functional theory (DFT) calculations, were used to investigate their structures and properties. The pyrene moieties were the primary location of the electron spin distribution, with a little overflow onto the outer thiophene moieties. Due to the different substituent groups, free radicals 1•+ 2•+ exhibit some different properties. Compound 1•+ is the most extensive thiophene-modified pyrene radical cation that has been reported. These species are anticipated to have wide-ranging potential in the areas of optoelectronic materials and semiconductors. thiophenemodified modified 12 1 2 (1)-(2 palladiumcatalyzed palladium catalyzed FriedelCrafts Friedel Crafts AgAlOCCF334 AgAlOCCF Ag Al OC CF3 3 4 CF Ag[Al(OC(CF3)3)4 1•+2•+ 1•+-2• NMR, NMR , (NMR) EPR, EPR (EPR) UVVis UV Vis spectroscopy DFT (DFT calculations properties distribution 1• 2• reported wideranging wide ranging semiconductors (1)-( AgAlOCCF33 Ag[Al(OC(CF3)3) 1•+2• 1•+-2 (NMR (EPR (1)- AgAlOCCF3 Ag[Al(OC(CF3)3 1•+2 1•+- (1) Ag[Al(OC(CF3) (1 Ag[Al(OC(CF3 ( Ag[Al(OC(CF

Abstract After performing localized repairs, it is customary to observe the reappearance of corrosion points in the region adjacent to the repaired area, a situation usually called the incipient anode phenomenon. Although there are several studies have on the subject, there are still controversial aspects regarding its causes, location, and progression over time. To investigate these gaps in knowledge, samples were molded with unrepaired chloride-contaminated substrate and repaired with repair mortar containing 0%, 10%, and 20% binder replacement with rice husk ash (RHA). Then, measurements of the electrochemical variables of density and corrosion potential were carried out, as well as the destructive inspection of part of the samples. After the measurements, an increase in corrosion rates was observed after the repair, in the repair-substrate interface. In the destructive inspection, significant deterioration also was observed in the repair-substrate interface region, as well as inside the substrate. Regarding the effect of replacing the binder with RHA, no relevant reduction in the incipient anode was identified in the mortars with 10% and 20% RHA. On the other hand, a possible reduction in the passivation capacity of mortar with 20% RHA content was noted. repairs area phenomenon subject causes location time knowledge chloridecontaminated chloride contaminated 0 0% 10 20 .

Resumo Após a realização de reparos localizados, costuma-se observar o ressurgimento de pontos de corrosão na região adjacente à área reparada, situação usualmente denominada ânodo incipiente. Embora tenham sido feitas diversas pesquisas a respeito do tema, ainda restam controversos aspectos em relação às suas causas, localização e progressão no tempo. Com objetivo de investigar essas lacunas no conhecimento, moldaram-se amostras com substrato contaminado por cloretos não reparadas e reparadas com argamassa de reparo contendo substituição de ligante por sílica de casca de arroz (SCA) nos teores de 0%, 10% e 20%. Em seguida, realizaram-se aferições das variáveis eletroquímicas de densidade e potencial de corrosão, bem como a inspeção destrutiva de parte das amostras. Após as aferições, observou-se aumento nas densidades de corrosão após o reparo, na interface substrato-reparo. Na inspeção destrutiva, também foi constatada deterioração significativa na interface reparo-substrato, bem como em algumas regiões no interior do substrato. Em relação ao efeito da substituição de ligante por SCA, não foi identificada redução relevante do ânodo incipiente nas argamassas com 10% e 20% de SCA.

Abstract Background Merkel cell polyomavirus (MCPyV), a human polyomavirus that is unequivocally linked to merkel cell carcinoma (MCC), has been found in association with keratinocytes carcinomas (KC), especially basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC). Nevertheless, there is scarce information about the possible involvement of MCPyV in the development of KC. Objectives To assess the presence of MCPyV DNA and Large-T Antigen (LT-Ag) via Polymerase Chain Reaction (PCR) and Immunohistochemistry (IHC) in cases of KC, and to correlate its presence with immunohistochemical markers p16, p53, and ki67, tumor type and subtype, sun-exposed location, and epidemiological data. Methods The prevalence of MCPyV DNA, LT-Ag, and immunohistochemical markers p16, p53, and ki67 was assessed by PCR and Immunohistochemistry (IHC) in 127 cases of KC, these results were correlated with tumor type and subtype, sun-exposed location, and epidemiological data. Results The MCPyV DNA was detected in 42.57% (43 of 101) cases by PCR, the LT-Ag was detected in 16.4% (20 of 122) of cases, p16 in 81.5% (97 of 119), p53 in 66.4% (83 of 125), ki67 in 89% (73 of 82). No correlation between MCPyV LT-Ag and DNA confronted with tumor type, subtype, location site, and immunohistochemical markers was found. A single correlation between the MCPyV LT-Ag and cSCC tumors and peri-tumoral lymphocyte cells was noted. Study limitations Further steps need to be taken to better evaluate the MCPyV influence and its possible role in KC carcinogenesis, as the evaluation of the virus genome state, the gene sequence that encodes LT-Ag in the KC tumor cells, and in situ hybridization for viral DNA or RNA in these cells. Conclusions Despite the frequent detection of MCPyV in KC, the data available so far does not support the hypothesis of a causal relationship between them.

The spatial analysis carried out demonstrated points of highest incidence of murders in Recife, census tracts with statistically significant highest risk in the city 2012-2016 (RR=5.7; p=0.031) and 2017-2021 (RR=1.8; p= 0.032) and protection 2012-2016 (RR= 0.3; p=0.001; 0.006 p=0.014) and 2017-2021 (RR=0.1; p=0.001; RR=0.1; p=0.001), and, the highest incidence of homicides in territories with the highest Social Deprivation Index (IPS).

The main aim of this article is to provide a practical diagnostic approach to phenocopies of Huntington disease (HD). These are defined as conditions characterized by a phenotype similar to HD but with no pathogenic repeat expansion in the HTT gene. Their frequency ranges from 2% to 40% depending on ethnicity and geographic location. The most frequent genetic causes are Huntington Disease-like 2/JHP3, followed by spinocerebellar ataxia genes (SCA17/TBP, SCA12/PPP2R2B and SCA3/ATXN3, CACNA1A), and frontotemporal dementia genes (C9orf72, and VCP). There is current recognition that a growing number of acquired causes can mimic HD. Autoimmune causes such as primary antiphospholipid syndrome, paraneoplastic chorea, and anti-IGLON5 antibodies, as well as stroke, and diabetes mellitus type 2 complications are the leading acquired causes of HD phenocopies. Finally, we provide practical recommendations on how to approach HD phenocopies considering age at onset, ethnicity, and geographic location of individuals.

Abstract Background Cutaneous squamous cell carcinoma (CSCC) is one of the most common types of skin cancer worldwide. Therefore, the identification of biomarkers associated with CSCC progression could aid in the early detection of high-risk squamous cell carcinoma and the development of novel therapeutic strategies. Objective This study aimed to investigate the expression patterns of silent mating type Information Regulation 2 homolog 6 (SIRT6) in CSCC and its clinical significance. Methods The protein expression level of SIRT6 in tissues was detected by immunohistochemistry, and the correlation between SIRT6 expression and clinicopathological parameters in CSCC patients was analyzed. The relative expression of SIRT6 in CSCC cell lineage and tissue specimens was determined by western blotting and PCR. The effect of SIRT6 silencing on cell proliferation was evaluated using cell counting kit 8. Wound healing, transwell method, and flow cytometry were used to investigate the migration, invasion, and cell cycle distribution/apoptosis of CSCC cells after SIRT6 silencing, respectively. Western blot was used to detect the expression of EMT (Epithelial-Mesenchymal Transition), cycle, apoptosis, and other related proteins. Results The high expression of SIRT6 was correlated with the location of cancer tissue and Broder staging in CSCC patients. Knockdown of SIRT6 inhibited the proliferation, migration, invasion and EMT of CSCC cells, and promoted their apoptosis, with cells blocked in G1 phase. Study limitations No animal experiments were conducted to further verify the results. Conclusion Decreased expression of SIRT6 can inhibit the occurrence and development of CSCC.

Abstract: The character in the oracle bone script is one that has yet to be deciphered and remains in dispute because of two main problems: i) it’s meaning, and ii) the location of the state that had this name. This article presents new ideas on the topic, based on the results and opinions of previous researchers, to help us better understand the scripts that contain this character, the historical evolution of related characters, and the geographical relationship in some historical events and the relationships between the Shang dynasty and neighboring states.

Resumen: El carácter de las inscripciones sobre huesos oraculares aún no ha sido descifrado y sigue en disputa debido principalmente a dos problemas: i) su significado, y ii) la ubicación del Estado que tenía ese nombre. Este artículo presenta ideas nuevas sobre el tema, con base en los resultados y las opiniones de investigadores anteriores, para ayudar a comprender mejor los textos inscritos que incluyen este carácter, la evolución histórica de los caracteres afines, y la relación geográfica entre determinados eventos históricos y las relaciones entre la dinastía Shang y los estados vecinos.

Resumen La carretera Puyo-Tena es propensa a deslizamientos de tierra debido a la geodinámica, geomorfología y materiales geológicos de la zona (afloramientos y estratos inestables). En los últimos años, este problema ha provocado de forma persistente la inutilización parcial o total de la carretera en numerosas ocasiones. El objetivo de la investigación fue generar un modelo cartográfico de susceptibilidad a deslizamientos a partir de variables como la pendiente, las formaciones geológicas, la cobertura y uso de la tierra, así como las distancias a fallas, carretera y ríos. El grado de incidencia de deslizamientos se estimó como la combinación lineal de las variables ponderadas mediante el proceso de jerarquía analítica. La importancia de este método semicuantitativo radica en su capacidad para desagregar un problema de decisión complejo en un modelo de decisión más simple y coherente. El modelo cartográfico resultante se reclasificó en cinco categorías de susceptibilidad: muy baja, baja, moderada, alta y muy alta. Los resultados mostraron que 17 km de los 80 km de la carretera Puyo-Tena tienen una alta probabilidad a deslizamientos, lo que equivale a 21,25% de la carretera. Además, dentro de este porcentaje, se determinó que existen quince regiones con alta probabilidad de deslizamientos debido a su ubicación en zonas con fuertes pendientes, litología porosa y permeable, gran cantidad de ríos y suelos agrícolas. Para la verificación del modelo se utilizó el área bajo la curva (en inglés AUC) de la característica operativa del receptor (en inglés ROC). Los resultados de la verificación mostraron que el modelo cartográfico para el área de estudio tiene un valor de precisión de 83,7%. El modelo cartográfico de susceptibilidad a deslizamientos permitirá tomar las decisiones pertinentes para mitigar eventos potenciales que puedan poner en peligro a transportistas, bienes materiales y residentes de la zona.

Abstract The Puyo-Tena roadway is prone to landslides due to the geodynamics, geomorphology, and geological materials of the area (unstable outcrops and strata). In recent years, this problem has persistently caused the road to be partially or completely disabled on numerous occasions. The objective of the research was to generate a cartographic model of landslides susceptibility based on variables such as slope, geological formations, land cover and land use, as well as distances to faults, road, and rivers. The degree of landslides incidence was estimated as the linear combination of the weighted variables using the analytic hierarchy process. The importance of this semi-quantitative method lies in its ability to break down a complex decision problem into a simpler and more coherent decision model. The resulting cartographic model was classified into five susceptibility categories: very low, low, moderate, high, and very high. The results showed that 17 km out of the 80 km of the Puyo-Tena roadway have a high probability of landslides, which is equivalent to 21.25% of the road. Furthermore, within this percentage, it was determined that there are fifteen regions with a high probability of landslides due to their location in areas with steep slopes, porous and permeable lithology, a large number of rivers, and agricultural soils. The area under the curve (AUC) of the receiver operating characteristic (ROC) was used for model verification. The verification results showed that the cartographic model for the study area has an accuracy value of 83.7%. The cartographic model of landslide susceptibility will enable relevant decisions to be made to mitigate potential hazards that may endanger transporters, material goods, and residents of the area.

ABSTRACT In a local context of strictly typological studies and with the absence of manuals for the study of ceramics related to the Puruhá archaeological culture, Sierra Central do Ecuador, we verified the possibility of associating the theoretical and methodological issue with archaeological practice, resulting in the location of ceramic production as an intrinsic subsystem understanding the sociocultural systems that define a cultural. With this premise, this manuscript presents a proposal for classification in archeology based on the analysis of contextualized or non-contextualized ceramic material culture through the application of the concepts of anthropology of techniques and operational chains associated with techno-typological analyzes with the case study of production Puruhá potter. Having as a methodological framework the inductive empirical method, with a qualitative approach that mixes literature review, conceptual insertion, technique and analysis, with an exploratory and non-experimental scope as a research design. The proposed archeological classification allowed us to check the feasibility and potential of its usage in a Puruhá setting, as well as its linkage with other sites, yielding a reading that allows us to draw conclusions regarding cultural continuities and changes.

Resumo Apesar da sua fama internacional durante a Idade Média, o nosso conhecimento do império do Mali permanece muito incompleto. Talvez a lacuna mais significativa seja o facto de a sua capital ainda não ter sido identificada de forma fiável. Este artigo oferece uma nova hipótese sobre a localização da capital imperial de Mali no século XIV. Baseia-se na observação de que os governantes do Mali, tal como os de outras formações políticas medievais africanas, assentavam o seu poder no controlo da interface entre redes mercantis opostas. Ao fazê-lo, tendiam a estabelecer a sua legitimidade política através do uso de títulos e de manifestações de poder político e religioso condizentes com os seus diferentes clientes e súbditos. Ter em consideração esta dualidade económica, religiosa e política permite-nos postular que a capital do Mali se encontrava fora do domínio real. Embora ainda não tenha sido investigada pela arqueologia, a localização hipotética da cidade proposta neste artigo corresponde às descrições árabes disponíveis.

Abstract Despite its international fame during the Middle Ages, our knowledge of the empire of Mâli remains patchy. Perhaps the most significant lacuna is that its capital has not yet been reliably identified. This paper offers a new hypothesis about the location of the imperial capital of Mâli in the 14th century. It is based on the observation that the rulers of Mâli, like those of other medieval African polities, strengthened their power by controlling the interface between opposite merchant networks. In doing so, they tended to establish their political legitimacy through the use of titles and displays of political and religious power befitting their different clients and subjects. Taking this economic, religious and political duality into consideration allows us to posit that the capital of Mâli lay outside the royal domain. Though it has not yet been probed by archaeology, the city’s hypothetical location proposed in this arricle corresponds to available Arabic descriptions.
