1. Diffusive Metrics Induced by Random Affinities on Graphs. An Application to the Transport Systems Related to the COVID-19 Setting for Buenos Aires (AMBA)
ABSTRACT The aim of this paper is to apply the diffusive metric technique defined by the spectral analysis of graph Laplacians to the set of the 41 cities belonging to AMBA, the largest urban concentration in Argentina, based on public transport and neighborhood. It could be expected that the propagation of any epidemic desease would follow the paths determi

2. Synthesis and Anti-Chikungunya Virus (CHIKV) Activity of Novel 1,4-Naphthoquinone Sulfonamide and Sulfonate Ester Derivatives
Chikungunya virus (CHIKV) is a re-emerging disease caused by an alphavirus of the Togaviridae family. Since its first description in 1952, the disease has spread worldwide, affecting populations in both tropical and temperate countries. To date, there is no licensed vaccine or specific pharmacological treatment. Therefore, there is an increasing urgency in d

3. The Prognostic Roles of PYCR2 and ZBTB18 Expression in Tissues of Colorectal Carcinoma and Non-Neoplastic Tissues: An Immunohistochemical Study
Abstract Background It is important to detect novel biomarkers responsible for the progression and spread of colorectal cancer (CRC) to better evaluate the prognosis of the patients, provide better management, and foster the development of therapeutic targets. In humans, pyrroline-5-carboxylate reductase 2 (PYCR2) is encoded on chromosome 1q42.12, and its m

4. THE EXPLORATORY DIMENSION OF FMRI EXPERIMENTS
Abstract Driven by an appreciation of the field’s early stage of development, I apply the concept of exploratory experimentation, originally put forward in the late 90s philosophy of biology, to current research in cognitive neuroscience. I concentrate on functional magnetic resonance imaging and how this wide-spread technique is used, from experimental de

5. Evaluation of mortars produced with Baosteel slag short flow (BSSF) steel slag as fine aggregate
Abstract The objective was to evaluate the influence of Baosteel slag short flow (BSSF) steel slag, a byproduct of a Brazilian steel mill, as a fine aggregate on the properties of fresh state and on the compressive strength of mortars. The experimental work was to characterize the BSSF steel slag and to produce simple mortars (only cement) and mixed mortars

6. Epidemiologia do esgoto como estratégia para monitoramento comunitário, mapeamento de focos emergentes e elaboração de sistemas de alerta rápido para COVID-19
The ability to monitor the spread of diseases is essential for prevention, intervention and control practices. In this context, wastewater-based epidemiology (WBE) has been applied to empirically evaluate the exposure of populations to chemical substances and pathogens of emerging concern in near real time. During the current COVID-19 pandemic, WBE remains a

7. Experimental poisoning by Crotalaria lanceolata and Crotalaria pallida seeds in broilers
RESUMO: Crotalaria lanceolata E. Mey. e Crotalaria pallida Aiton. são leguminosas da família Fabaceae presentes na maioria do território brasileiro. Inicialmente foram utilizadas como adubação verde e devido sua fácil disseminação são consideradas invasoras de culturas. Através da colheita mecanizada da soja e milho pode ocorrer a contaminação de

8. Autochthonous canine visceral leishmaniasis cases occur in Paraná state since 2012: isolation and identification of Leishmania infantum
Resumo O objetivo deste estudo foi confirmar a emergência da leishmaniose visceral canina em Foz do Iguaçu próximo à fronteira com a Argentina e ao Paraguai, por meio do isolamento e identificação molecular de Leishmania infantum. Em um primeiro estágio de coleta de animais (2012), três amostras de aspirados de linfonodos e 46 camadas leucocitárias

9. Molecular characterization of the invasive aquatic macrophyte Hydrilla verticillata (Hydrocharitaceae) in Brazil
Abstract: Invasive populations of macrophytes are widely distributed and have been successfully introduced and established in freshwater habitats. Hydrilla verticillata was first recorded in 2005 in the Upper Paraná River floodplain and in 2007 at the Itaipu Reservoir (Brazil-Paraguay border, ca. 300 km downstream from its first record). However, its geneti

11. Molecular farming of antimicrobial peptides: available platforms and strategies for improving protein biosynthesis using modified virus vectors
Abstract The constant demand for new antibiotic drugs has driven efforts by the scientific community to prospect for peptides with a broad spectrum of action. In this context, antimicrobial peptides (AMPs) have acquired great scientific importance in recent years due to their ability to possess antimicrobial and immunomodulatory activity. In the last two dec

12. Lipoxygenase inhibitors flavonoids from Cyperus rotundus aerial parts
ABSTRACT Cyperus rotundus L. (Suada, Sueda, family: Cyperaceae) is vastly spread in several world's subtropical and tropical regions. It had variable traditional uses and bioactivities. A new flavonol derivative: cyperaflavoside (myricetin 3,3',5'-trimethyl ether 7-O-β-D-glucopyranoside) and five flavonoids: vitexin, orientin, cinaroside, quercetin 3-O-β-D
