This study aimed to assess the inflammation and apoptosis in inflammatory cells and presents a unique description of the presence of autophagic and apoptotic Leishmania amastigotes in naturally Leishmania-infected dogs.

Mast cells and factor XIIIa+ dendrocytes in actinic cheilitis and lip squamous cell carcinoma.

There is an interaction between dendrocytes and mast cells in the skin. However, in elastosis-related diseases such as actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC), this interaction remains unknown. We investigated the presence of intact and degranulated mast cells in AC and LLSCC.

Systems Immunology Approaches to Understanding Immune Responses in Acute Infection of Yellow Fever Patients.

In the 2018 yellow fever (YF) outbreak in Brazil, we generated new transcriptomic data and combined it with clinical and immunological data to decode the pathogenesis of YF. Analyzing 79 patients, we found distinct gene expression patterns between acute YF, other viral infections, and the milder YF-17D vaccine infection. We identified a critical role for low-density, immature neutrophils in severe outcomes, marked by the downregulation of genes essential for neutrophil migration and maturation, such as PADI4, CSF3R, and ICAM1, in deceased patients.

[Estimates of mortality from external causes in Brazil, 2010-2019: methodology for redistribution of garbage causes].

Insufficient quality of the underlying cause of death in the Brazilian Mortality Information System (SIM), acronym in Portuguese underlists violence and it is necessary to redistribute garbage causes (GC) into valid causes in public health prevention. This study estimated mortality from external causes using the GC redistribution method (GBD-Brazil) and compared it with SIM and estimated data from the GBD-IHME study from 2010 to 2019 in Brazil and its states. The GBD-Brazil GC redistribution algorithm applies previous steps of the GBD-IHME with modifications, using two criteria: proportion of target causes (valid) or reclassification of investigated causes.

Method: This cross-sectional observational study with 442 firefighters collected data on sociodemographic, occupational, and lifestyle aspects and screening for common mental disorders (CMD). Individuals were divided into two groups: those slightly likely and those moderately/highly likely to have dysphonia, according to the Brazilian Dysphonia Screening Tool.

The ventral midline thalamus and long-term memory: What consolidation, what retrieval, what plasticity in rodents?

The ventral midline thalamus, including the reuniens and rhomboid (ReRh) nuclei, connects bidirectionally with the medial prefrontal cortex (mPFC) and hippocampus (Hip), both essential for memory processes. This review compiles and discusses studies on a role for the ReRh nuclei in the system consolidation of memories, also considering their potentially limited participation in memory retrieval or early phases of consolidation. It also examines scientific literature on short- and long-term plasticity in ReRh-mPFC and ReRh-Hip connections, emphasizing plasticity's importance in understanding these nuclei's role in memory.
