Sustainable Production and In Vitro Giardicidal Activity of Bioactive Compounds Derived from Arthrospira PlatensisNARA Subscribed
Background Giardiasis remains a globally prevalent neglected parasitic disease, and limitations associated with conventional therapies highlight the need for alternative and complementary strategies. In this context, microalgae biocompounds have emerged as promising sources of antiparasitic agents. Objective This study aims to evaluate the in vitro preliminary screening activity (vital dye exclusion). Methods Aqueous extracts...
The objective of this study was to assess the infection rate of Anaplasma marginale in cattle by Rhipicephalus microplus . Two experiments were conducted for this purpose. Experiment 1 evaluated the infection rate by the intrastadial and transstadial routes. Calves naturally infected with A. marginale were infested with R. microplus and were called “positive with ticks” (PWT). These PWT animals were housed together with A. mar...
Small ruminant lentiviruses in dairy goats under tropical conditions: evidence of recombinant genotypesNARA Subscribed
Small Ruminant Lentiviruses (SRLVs) are widespread retroviruses of goats and sheep with significant economic and health impacts on small ruminant production systems. This study aimed to investigate the prevalence and genotype distribution of SRLVs in dairy goat flocks from Brazil. A total of 433 blood samples from eight dairy goat farms were analyzed via PCR targeting the gag gene. The overall SRLV prevalence was 32.6%, with m...
Peripheral microRNA signature in genetic frontotemporal dementia—findings from the GENFI initiativeNARA Subscribed
Frontotemporal dementia (FTD) is a neurodegenerative disease characterized by significant clinical and genetic heterogeneity, with approximately 40% of cases linked to hereditary genetic mutations, including MAPT , GRN , and C9ORF72 . Recently, microRNAs (miRNAs) have emerged as key regulators of cellular processes related to neurodegeneration and as potential biomarkers for FTD. However, their relevance in presymptomatic stag...
Records for ticks (Acari: Ixodidae) on free-ranging Coendou spinosus from State of São Paulo, BrazilNARA Subscribed
Ticks and tick-borne diseases have spread since the mid-twentieth century largely due to major anthropogenic changes impacting natural ecosystems. The Coendou spinosus is a medium sized rodent found in the southeast of Brazil. There is little information about the presence and richness of ticks on porcupines. The objective of this study was to identified ticks collected from C. spinosus received at a triage center of wildlife...
Micro‐Refuges or Ecological Traps: Context‐Dependent Effects of Rock Pools on Intertidal Biodiversity Across LatitudesNARA Subscribed
Aim We investigated how local‐scale environmental heterogeneity influences biodiversity patterns across broad biogeographic gradients, using intertidal microhabitats as a model system within one of the most environmentally stressful ecosystems on Earth. Location Intertidal habitats at 26 locations (two rocky shore sites per location) across six continents, spanning 98° of latitude (38°S to 60°N). Time Period 2019–2022. Major T...
The potential arrival of Halyomorpha halys in New Zealand jeopardizes a vast range of crops. Therefore, different preparedness strategies are being assessed before its arrival. A symbiont-targeted control strategy might be used along with other control tactics such as biological control. Prior its implementation, it is necessary to assess its potential impact on non-target stink bug species and their associated egg parasitoids...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
