Leishmaniasis is a neglected tropical disease caused by protozoans of the Leishmania genus, against which no effective treatment or control is available. Like other eukaryotes, parasite telomeres are maintained by telomerase, a ribonucleoprotein complex vital for genome stability. Its protein component, TERT (telomerase reverse transcriptase), presents four structural and functional domains, with the TEN (Telomerase N-terminal) and TRBD (Telomerase RNA-binding) located at its N-terminal.

When a species is introduced in a new location, it is common for it to establish itself when it finds favorable conditions in the receptor community with regard to interspecific interactions with native species. The azooxanthellate corals coccinea and are invasive species introduced in the Caribbean Sea, the Gulf of Mexico, and the Brazilian Southwest Atlantic. They are successful competitors for space, have multiple reproductive modes, and have high larval dispersion and recruitment, but studies on food and trophic relationships of the genus are still scarce.

Differentiating subjects through the comparison of their recorded speech is a common endeavor in speaker characterization. When using an acoustic-based approach, this task typically involves scrutinizing specific acoustic parameters and assessing their discriminatory capacity. This experimental study aimed to evaluate the speaker discriminatory power of vowel formants-resonance peaks in the vocal tract-in two different speaking styles: Dialogue and Interview.

Given psychologists' role and the use of psychotherapies for sleep issues, our study explored: (1) whether psychologists inquire about patients' sleep quality and their beliefs regarding the relationship between mental health and biological rhythms, and (2) global trends in psychological approaches through a bibliometric analysis. We analyzed responses from 1011 Brazilian clinical psychologists (October 2018-May 2019) and found that most routinely inquire about sleep quality and address sleep problems, while a small portion did not perceive a direct link between mental disorders and biological rhythms. Behavioral psychotherapy practitioners showed greater interest in sleep quality.

The conservation of the predatory ladybird beetle, (Germar) after its release also relies on its resistance and the performance of its progenies. When resistant individuals are released or evolve in the field through mating with susceptible pairs, we anticipate that they will generate a resistant progeny, inheriting the resistance to lambda-cyhalothrin through an autosomal mechanism. The susceptibility of a field-collected population (EcGA) was characterized and determined by the performance of their progenies generated through mating with a resistant parent (EcViR).

Introduction: The incidence of anal squamous cell carcinoma (SCC) has been increasing over the last decades. Human papillomavirus (HPV) infection accounts for more than 90% of anal cancers, and HIV co-infection increases the risk of invasive cancer. Men who have sex with men (MSM) with HIV are the highest risk group for developing anal high-grade squamous intraepithelial lesions (aHSILs), which can be found in 45%-50% of these patients and are precursor lesions for invasive cancer.

To evaluate whether the presence of proteinuria, although no longer mandatory in the revised diagnostic criteria, results in worse maternal and fetal outcomes in preeclampsia (PE). A retrospective cohort study was conducted, analyzing data from pregnant patients diagnosed with PE between January 2015 and December 2019 at a tertiary care center in Brazil. Ethical approval was obtained, and the patient records were reviewed to assess maternal and perinatal outcomes based on the revised diagnostic criteria by the College of Obstetricians and Gynecologists, focusing on the presence or absence of proteinuria.

This work investigated the operational and microbiological aspects of the decolorization of the azo dye Reactive Black 5 in acidogenic reactors followed by aerobic granular sludge (AGS) reactors, evaluating the effect of the acidogenic hydraulic retention time (HRT) (3, 2, and 1 h), effluent recirculation in the AGS reactor (50 mL min), dye concentration (50 and 100 mg L), and the redox mediator sodium anthraquinone-2-disulfonate (AQS) (50 μM). The acidogenic reactors were mainly responsible for the dye decolorization, with AQS significantly improving its efficiency and enabling the use of a shorter HRT (2 h). The recirculation effect was not so evident, probably masked by the adaptation of the acidogenic microbiota.

Aberrant signaling through damage-associated molecular patterns (DAMPs) has been linked to several health disorders, attracting considerable research interest over the last decade. Adenosine triphosphate (ATP), a key extracellular DAMP, activates the purinergic receptor P2X7, which acts as a danger sensor in immune cells and is implicated in distinct biological functions, including cell death, production of pro-inflammatory cytokines, and defense against microorganisms. In addition to driving inflammation mediated by immune and non-immune cells, the persistent release of endogenous DAMPs, including ATP, has been shown to result in epigenetic modifications.

Article Synopsis
  • Candida species, especially Candida albicans, are the most common fungal pathogens in humans, but there’s been a rise in non-albicans Candida species (NACs) which show increased antifungal resistance.
  • Recent research on a copper(II) coordination compound known as CTP has revealed its ability to effectively target and damage antifungal-resistant NACs by affecting their mitochondrial function and causing significant surface alterations.
  • CTP not only inhibits biofilm formation by these invasive species but also disrupts established biofilms, making it a promising candidate for developing new antifungal treatments.
