Alterations in miRNA Expression and Their Role in the Pathogenesis of Cervical Cancer.

Background: Cervical cancer has a high incidence and mortality rate, affecting more than half a million women in 2018. Its development is strongly related to high-risk HPV infection. After infection, several cellular molecules are affected, including microRNAs (miRNAs), which are the focus of our study.

Alteration in the Expression of Circular Rnas and its association with the Development and Progression of Osteosarcoma, an Integrative Review with High Sensitivity Research.

Background: Osteosarcoma is the most common primary malignant bone tumor, mainly affecting children, young adults, and the elderly. It is an aggressive cancer with a poor prognosis, exhibiting low survival rates even with standard treatment. Recently, circular RNA molecules capable of influencing gene expression through various functions, with their main role being acting as microRNA sponges and reducing their intracellular expression, have been identified.

Viruses as a potential environmental trigger of type 1 diabetes mellitus (Review).

The etiopathogenesis of type 1 diabetes mellitus (T1DM) is a complex multifactorial process that involves an intricate network of genetic, epigenetic, immunological, and environmental factors. Despite the advances in recent years, some aspects of the mechanisms involved in triggering the disease are still unclear. Infections with certain viruses have been suggested as possible environmental triggers for the autoimmune process that leads to selective and progressive destruction of pancreatic β-cells and insufficiency of insulin production, which is its hallmark.

A destructive sinonasal organizing hematoma mimicking malignancy.

Sinonasal organizing hematomas (SOH) are rare, benign lesions that can be mistaken for malignancies due to their unfamiliarity among clinicians and aggressive appearance on imaging, which can lead to aggressive and unnecessary therapeutic interventions. Herein, we report an unusual case of SOH in an 87-year-old female patient who sought care at a maxillofacial surgery service due to persistent right nasal obstruction and imaging findings that suggested the possibility of sinonasal malignancy. We highlight the importance of recognizing these lesions to ensure adequate treatment through a conservative approach.

Virulence of Strains Is Related to the Differential Expression of Innate Immune Receptors in the Heart.

Resistance or susceptibility to infection is dependent on the host immunological profile. Innate immune receptors, such as Toll-like receptors (TLRs/TLR2, TLR4, TLR7, and TLR9) and Nod-like receptors (NLRs/NOD1 and NLRP3 inflammasome) are involved with the resistance against acute experimental infection. Here, we evaluated the impact of virulence on the expression of innate immune receptors and its products in mice.

Level of pain and quality of life of people living with HIV/AIDS pain and quality of life in HIV/AIDS.

The aim of this descriptive study was to correlate the level of pain with the quality of life in 261 people living with HIV/AIDS. Mild pain/no pain was reported by 47.5% of subjects, 24.

Quality of Life, Family Support, and Comorbidities in Institutionalized Elders With and Without Symptoms of Depression.

The institutionalization of elders can decrease the health status and quality of life in this population. The aim of this study was to analyze the socio-demographic, quality of life, family support, and comorbidities variables in institutionalized elders with and without symptoms of depression. This was a cross-sectional study in institutions for long permanence for the elderly in the State of Rio Grande do Norte, Brazil.

Adoption of photoprotection measures on lip and perioral regions among beach workers in North Brazil.

Background: Workers from various occupational groups stand out as being more susceptible to photodamage. Behaviors that can reduce the risk of onset of these disorders include the limitation or reduction of sun exposure, use of photoprotective clothing, and correct use of sunscreen. The present study aimed to verify the use of photoprotection measures by beach workers on the lips and perioral regions, as well as investigate possible associations with sociodemographic, occupational, and health variables.

Validation of an equation for estimating maximal oxygen consumption of nonexpert adult swimmers.

Objective: To validate an equation to estimate the maximal oxygen consumption (VO2max) of nonexpert adult swimmers.

Methods: Participants were 22 nonexpert swimmers, male, aged between 18 and 30 years (age: 23.1 ± 3:59 years; body mass: 73.

Reproducibility of an aerobic endurance test for nonexpert swimmers.

Background: This study aimed to verify the reproduction of an aerobic test to determine nonexpert swimmers' resistance.

Methods: The sample consisted of 24 male swimmers (age: 22.79 ± 3.
