Atypical case of recurrent otitis with polyp formation in the ear canal associated with lagochilascariasis in a domestic feline in Brazil.

Lagochilascariasis is a neglected zoonosis that affects domestic and wild mammals, including humans, and can form nodules, especially on the neck. Although emerging, it is considered a rare disease in the Americas and, therefore, the objective was to report an atypical case of recurrent otitis with the formation of polyps in the ear canal in a domestic feline associated with lagochilascariasis in Brazil. A cat had a purulent exudate in one of her ears and responded poorly to treatments.

De novo and inherited dominant variants in U4 and U6 snRNAs cause retinitis pigmentosa.

The U4 small nuclear RNA (snRNA) forms a duplex with the U6 snRNA and, together with U5 and ~30 proteins, is part of the U4/U6.U5 tri-snRNP complex, located at the core of the major spliceosome. Recently, recurrent variants in the U4 RNA, transcribed from the gene, and in at least two other genes were discovered to cause neurodevelopmental disorder.

Diagnosis of spp. in ruminants at Southern Brazil.

spp. is a flagellated protozoan that parasitizes the small intestine of various mammals, birds, and amphibians, being transmitted via the fecal-oral route. Giardiasis is one of the most prevalent parasitic diseases in both developed and developing countries, with a prevalence of 0,1-5% and 20-30%, respectively, and is correlated with poor hygiene practices, such as irregular handwashing, which consequently contaminates food when handled.

Analyzing and mitigating the risks of patient harm during operating room to intensive care unit patient handoffs.

Patients continue to suffer from preventable harm and uneven quality outcomes. Reliable clinical outcomes depend on the quality of robust administrative systems and reliable support processes. Critically ill patient handoffs from the operating room (OR) to the intensive care unit (ICU) are known to be high-risk events.

Developing an HIV-specific falls risk prediction model with a novel clinical index: a systematic review and meta-analysis method.

Background: Falls are a common problem experienced by people living with HIV yet predictive models specific to this population remain underdeveloped. We aimed to identify, assess and stratify the predictive strength of various physiological, behavioral, and HIV-specific factors associated with falls among people living with HIV and inform a predictive model for fall prevention.

Methods: Systematic review and meta-analysis were conducted to explore predictors of falls in people living with HIV.

Hippocrepis fuelleborni (Digenea: Notocotylidae) from Argentina, morphological, molecular and phylogenetic studies.

Notocotylidae is a family with a cosmopolitan distribution, with 13 genera parasitizing birds and mammals. Four of these genera were registered in the Americas, and two parasitizing rodents in Argentina. In this paper, specimens of the genus Hippocrepis parasitizing Holochilus brasiliensis from Argentina are studied on the basis of morphological and molecular characteristics.

An optimization protocol of the volatile organic compounds analysis in earwax samples for untargeted volatilomics.

Recent studies have highlighted the potential of earwax or cerumen, a non-conventional biomatrix, in volatilomics research as a valuable matrix for disease biomarker discovery. Despite that, there are still gaps in using non-conventional biomatrices in metabolomics research. In this sense, this study aimed to elucidate the main analytical factors involved in the extraction and analysis of volatile organic compounds (VOCs) in cerumen by headspace/gas chromatography-mass spectrometry (HS/GC-MS) using Design of Experiments (DoE) approaches.

Combinatory Effect of Pequi Oil ()-Based Nanoemulsions Associated to Docetaxel and Anacardic Acid () in Triple-Negative Breast Cancer Cells In Vitro.

Combination therapy integrated with nanotechnology offers a promising alternative for breast cancer treatment. The inclusion of pequi oil, anacardic acid (AA), and docetaxel (DTX) in a nanoemulsion can amplify the antitumor effects of each molecule while reducing adverse effects. Therefore, the study aims to develop pequi oil-based nanoemulsions (PeNE) containing DTX (PDTX) or AA (PAA) and to evaluate their cytotoxicity against triple-negative breast cancer cells (4T1) in vitro.

First record of Contracaecum australe (Nematoda: Anisakidae) infecting Neotropic cormorant (Phalacrocorax brasilianus) (Aves: Phalacrocoracidae) in southern Brazil with a phylogenetic analysis.

Phalacrocorax brasilianus (Gmelin, 1789) (Aves: Phalacrocoracidae) is one of the few piscivorous birds inhabiting freshwater and saline environments, being considered one of the most abundant aquatic species in Rio Grande do Sul, Brazil, especially along the state's coastline. It is known that birds are hosts to a wide variety of disease-causing agents, among them, nematodes of the Contracaecum (Anisakidae) have a large number of recognized species. However, little is still known about the occurrence of these parasites in the Southern region of Brazil.

Can acclimation of freshwater rotifers to silver nanoparticles or 5-fluorouracil influence their multi- and transgenerational effects?

Emerging chemical contaminants (ECCs) are among the major environmental threats in present century. A variety of ECCs is released into aquatic environments with little knowledge about their long-term impacts to organisms. We examined the role of acclimation of the freshwater rotifer Brachionus calyciflorus to silver nanoparticles (Ag-NPs) and 5-fluorouracil (5-FU) for determining their ability to deal with these ECCs individually and in mixtures along multiple generations.
