Copper is an essential metal for cellular processes such as detoxification of reactive oxygen species, oxidative phosphorylation, and iron uptake. However, during infection, the host restricts the bioavailability of this micronutrient to the pathogen as a strategy to combat infection. Recently, we have shown the involvement of miRNAs as an adaptive strategy of P.

Dengue necessitates accurate diagnosis. Rapid tests such as Bioline™ DENGUE DUO have gained traction, but validation in specific populations is essential. This study aimed to evaluate the performance of the Bioline™ test, alongside assessing the socio-epidemiological profile of symptomatic patients in a Brasília Military Hospital.

Background: Arboviral diseases are a group of infectious diseases caused by viruses transmitted by arthropods, mainly mosquitoes. These diseases, such as those caused by the dengue (DENV), Zika (ZIKV), chikungunya (CHIKV), and yellow fever (YFV) viruses, have a significant impact worldwide. In this context, entomological surveillance plays a crucial role in the control and prevention of arboviruses by providing essential information on the presence, distribution, and activity of vector mosquitoes.

The diagnosis of Chikungunya (CHIKV), along with the simultaneous monitoring of virus circulation in the population or vectors, is essential for global health. Although effective diagnostic methods for CHIKV, such as RT-qPCR, exist, their utilization is constrained by high costs. With the aim of contributing to the field of diagnostics, we have developed a diagnostic assay using isothermal amplification technology with visually interpretable results.

Background: Arboviruses are a group of viruses transmitted to vertebrate hosts by certain blood-feeding arthropods. Among urban vectors of arboviruses, mosquitoes of the genus Aedes are the most common. However, other mosquitoes may be susceptible to infection and involved in the transmission, such as Mansonia spp.

Inducing immunogenic cell death (ICD) during cancer therapy is a major challenge that might significantly improve patient survival. The purpose of this study was to develop a theranostic nanocarrier, capable both of conveying a cytotoxic thermal dose when mediating photothermal therapy (PTT) after its intravenous delivery, and of consequently inducing ICD, improving survival. The nanocarrier consists of red blood cell membranes (RBCm) embedding the near-infrared dye IR-780 (IR) and camouflaging Mn-ferrite nanoparticles (RBCm-IR-Mn).

Zinc is one of the main micronutrients for all organisms. One of the defense mechanisms used by the host includes the sequestration of metals used in fungal metabolism, such as iron and zinc. There are several mechanisms that maintain the balance in the intracellular zinc supply.

Despite the advance of vaccination worldwide, epidemic waves caused by more transmissible and immune evasive genetic variants of SARS-CoV-2 have sustained the ongoing pandemic of COVID-19. Monitoring such variants is expensive, as it usually relies on whole-genome sequencing methods. Therefore, it is necessary to develop alternatives that could help identify samples from specific variants.

It is well known that the new coronavirus pandemic has global environmental, public health, and economic implications. In this sense, this study aims to monitor SARS-CoV-2 in the largest wastewater treatment plant of Goiânia, which processes wastewater from more than 700,000 inhabitants, and to correlate the molecular and clinical data collected. Influent and effluent samples were collected at Dr.

The genus Paracoccidioides comprises the species complex causing paracoccidioidomycoses (PCM). These fungi are a serious public health problem due to the long-term drug therapy, follow-up treatment, and frequent sequelae generated by the infection, such as pulmonary fibrosis. In this sense, the objective of this work was to generate bioluminescent reporter strains of Paracoccidioides spp.

The Arboviral diseases are caused by arthropod-borne viruses, such as Mayaro virus (MAYV), the etiological agent of Mayaro fever. This disease has been drawing the attention of the public health authorities for the increased number of cases likely due to virus adaptation for survival to urban areas as well as infection and multiplication in other vectors insects. Therefore, this work aimed to identify the MAYV infecting Aedes aegypti mosquitoes in Goiânia, the capital of state of Goiás, Brazil.

is a genus of thermodimorphic fungi that causes paracoccidioidomycosis. When in the host, the fungus undergoes several challenges, including iron deprivation imposed by nutritional immunity. In response to the iron deprivation triggered by the host, the fungus responds in a ternary manner using mechanisms of high affinity and specificity for the uptake of Fe, namely non-classical reductive iron uptake pathway, uptake of host iron proteins, and biosynthesis and uptake of siderophores.

Copper is an essential micronutrient for the performance of important biochemical processes such as respiration detoxification, and uptake of metals like iron. Studies have shown that copper deprivation is a strategy used by the host against pathogenic fungi such as and during growth and development of infections in the lungs and kidneys. Although there are some studies, little is known about the impact of copper deprivation in members of the genus.

Article Synopsis
  • * Researchers predicted the structure of FglA and found that its gene is conserved across all Paracoccidioides species, with higher levels of expression during hypoxia, suggesting its significance for fungal survival.
  • * A knockdown of FglA in P. brasiliensis resulted in reduced growth under low oxygen, indicating its essential role, while also suggesting a link between FglA and iron metabolism, with implications for understanding fungal infections.
