Leishmania presents a complex life cycle that involves both invertebrate and vertebrate hosts. By regulating gene expression, protein synthesis, and metabolism, the parasite can adapt to various environmental conditions. This regulation occurs mainly at the post-transcriptional level and may involve epitranscriptomic modifications of RNAs.

Asthma is a complex disease with varied clinical manifestations resulting from the interaction between environmental and genetic factors. While chronic airway inflammation and hyperresponsiveness are central features, the etiology of asthma is multifaceted, leading to a diversity of phenotypes and endotypes. Although most research into the genetics of asthma focused on the analysis of single nucleotide polymorphisms (SNPs), studies highlight the importance of structural variations, such as copy number variations (CNVs), in the inheritance of complex characteristics, but their role has not yet been fully elucidated in asthma.

This study evaluated the association between dental infection and maxillary sinus pathology, and the influence of age, sex, type of tooth, root proximity to the sinus floor, the condition of the primary maxillary ostium, and the presence of an accessory maxillary ostium in this process. Computed Tomography scans were selected, and upper posterior teeth were evaluated for the presence of apical periodontitis (AP), bone loss with furcation involvement, and endoperiodontal lesion (EPL), subsequently, sinuses were evaluated for mucosal thickening (MT) and opacification of the maxillary sinus (OMS). Logistic regression models were constructed, and Chi-squared and Fisher's tests were applied.

Extracellular vesicles (EVs)-mediated communication by cancer cells contributes towards the pro-tumoral reprogramming of the tumor microenvironment. Viral infection has been observed to alter the biogenesis and cargo of EVs secreted from host cells in the context of infectious biology. However, the impact of oncolytic viruses on the cargo and function of EVs released by cancer cells remains unknown.

Introduction: Until now, the thyroid cancer case number has increased, and it is not entirely possible to attribute this continuous growth to more meticulous thyroid nodule selection and more accurate diagnostic techniques. While there is currently no conclusive evidence linking dietary factors to thyroid cancer, certain dietary patterns seem to have an impact on the development of the disease. There are interesting connections among diet, environment, metabolism and thyroid carcinogenesis; a deeper comprehension of the underlying mechanisms should help the identification of modifiable risk factors for thyroid cancer.

Introduction: Carbapenemase-producing Enterobacterales (CPE) is a global threat. We evaluate the prevalence of CPE among isolates categorized as meropenem-susceptible, but that meet the European Committee on Antimicrobial Susceptibility Testing (EUCAST) screening cut-off values for carbapenemase detection, and analyze the susceptibility of these isolates to new available drugs.
Methods: We analyzed 257 isolates from patients hospitalized in a tertiary hospital in Brazil, from July 2022 to April 2023.

This study investigates essential (Mg, Ca, Fe, Mn, Cu, Zn, Se, Ni) and non-essential (Li, Be, Cr, Rb, Sr, Cs, Cd, Sn, Ba, and Pb) element concentrations and stable isotope (δC, δN, δS) compositions in feathers of Brown Boobies (Sula leucogaster) from three distinct Atlantic islands: the Archipelagos of Saint Peter and Saint Paul (SPSP), Abrolhos, and Cagarras. We aimed to investigate the ecological and environmental factors influencing these seabird populations and assess potential variations in contaminant exposure and dietary habits based on location, sex, and maturity stages. Our finding revealed significant geographical differences in trace element concentrations.

The selection and expression of conspicuous colorations in animals is often related to anti-predation strategies and sociosexual communication. The giant river prawn, Macrobrachium rosenbergii (de Man, 1879) is a species with three male morphotypes that vary in claws' coloration and the size of the animals. It has been suggested that male reproductive quality might be associated to their coloration, but evidence is still conflicting.

Recent advances in genomic methodologies have significantly enhanced our understanding of immune-mediated rheumatic diseases. Specific structural variants (SVs), such as substantial DNA deletions or insertions, including chromosomal aberrations, have been implicated in diseases of immune dysregulation. Regrettably, SVs are frequently overlooked in next-generation sequencing (NGS) targeted-gene panels, whole exome sequencing (WES) and whole genome sequencing (WGS).

The oncoprotein c-Myc is expressed in all breast cancer subtypes, but its expression is higher in triple-negative breast cancer (TNBC) compared to estrogen receptor (ER+), progesterone receptor (PR+), or human epidermal growth factor receptor 2 (HER2+) positive tumors. The c-Myc gene is crucial for tumor progression and therapy resistance, impacting cell proliferation, differentiation, senescence, angiogenesis, immune evasion, metabolism, invasion, autophagy, apoptosis, chromosomal instability, and protein biosynthesis. Targeting c-Myc has emerged as a potential therapeutic strategy for TNBC, a highly aggressive and deadly breast cancer form.

Black-goggled tanagers Trichothraupis melanops (Vieillot, 1818) are passerine birds commonly observed in the Brazilian Atlantic Forest, Argentina and Paraguay. Tanagers are among the passerines with the highest prevalence and density of coccidian parasites, mainly due to their frugivorous feeding habits that favor fecal-oral transmission. In this context, the current study identifies a new species of Isospora Schneider, 1881 parasitizing black-goggled tanagers captured in the Itatiaia National Park, a protected area with a high degree of vulnerability in Southeastern Brazil.

This study investigated whether luteinizing hormone receptor (LHR) expression varies in the granulosa cells of individual follicles according to the maturation stage of the oocytes harvested for assisted reproductive technology (ART) treatment. We observed minimal to no LHR mRNA and protein expression in cumulus cells surrounding oocytes arrested in the germinal vesicle (GV) stage. Interestingly, their ability to mature was confirmed by rescue in vitro maturation, suggesting somatic cell LHR deficiency as a key factor for the retrieval of GV oocytes in ART procedures.

Obesity is a chronic inflammatory disease that affects more than 1 billion people worldwide and is associated with various metabolic and physiological dysfunctions, directly impacting the dynamics of the immune response, partly due to elevated leptin levels. Leptin is an important peptide hormone that regulates neuroendocrine function and energy homeostasis, with its blood levels reflecting energy reserves, fat mass, or energy deprivation. This hormone also plays a fundamental role in regulating immune function, including the activity of NK cells, which are essential components in antiviral and antitumor activity.

The challenge of increasing food production while maintaining environmental sustainability can be addressed by using biofertilizers such as Azospirillum, which can enhance plant growth and colonize more than 100 plant species. The success of this biotechnology depends on the amount of plant growth-promoting bacteria associated with the plant during crop development. However, monitoring bacterial population dynamics after inoculation requires time-consuming, laborious, and costly procedures.
