In this report, we present a case of a triple clavicle injury, acromioclavicular joint (ACJ) dislocation, a middle third clavicle fracture, and a sternoclavicular joint (SCJ) subluxation, and describe its successful surgical treatment. A 49-year-old female patient sustained a 3 m fall, resulting in direct trauma to her left shoulder. Initial radiographs and computed tomography (CT) scans revealed a displaced middle third clavicle fracture, a high-grade ACJ dislocation, and a posterior SCJ subluxation.

Physical training (via eNOS/NO) and intake of nitrite have been considered major stimuli to increase NO.
Objective: We examined the effects of oral nitrite administration and aerobic exercise training on BP and arterial stiffness in Wistar rats.

Objective: To translate and cross-culturally adapt the University of Wisconsin Running Injury and Recovery (UWRI) to Brazilian Portuguese (UWRI-BR) and assess its psychometric properties.
Methods: The Brazilian version of the UWRI questionnaire was based on the guideline proposed by Guillemin. The UWRI was translated, back-translated, and culturally adapted.
The sanitation resource recovery is a contemporary strategy fully in line with the concept of the circular economy. The by-products from constructed wetlands technology include treated water, nutrients, biomass and energy. The aim of the present study was to evaluate the sewage treatment and resources recovery in constructed wetlands operating in a tidal flow configuration, coupled with microbial fuel cells (MFC).

Recently, we showed that COVID-19 increases extracellular ATP levels, which may amplify the pro-inflammatory signals in the disease. The P2X7 receptor can be a protagonist in the pro-inflammatory responses.

Their limited efficacy in chronic phase of the disease, problems of toxicity and the growing resistance by the protozoan are directly associated to high rates of drug discontinuation by the patients. In the context of the search for new trypanocidal drug candidates, our group has been working with the chemical manipulation of eugenol to obtain new agents active against T.

The Minimum Inhibitory Concentration (MIC) was determined to evaluate the antibacterial activity and antibiotic potentiation against Pseudomonas aeruginosa and Staphylococcus aureus, as well as to analyze the inhibition of efflux pumps in S. aureus strains 1199B and K2068 in the ethidium bromide assay.

Herpes simplex virus type 1 (HSV1) enhances HIV-1 replication and has evolved mechanisms to evade or disrupt host innate immune responses, including interference with interferon (IFN) signalling pathways.
Objectives: The aimed of this work was evaluated whether it HSV1 affects HIV-1 replication through the modulation of the IFN pathway in human macrophages.

Background: Human immunodeficiency virus (HIV)-1 infection can activate the expression of human endogenous retroviruses (HERVs), particularly HERV-K (HML-2). HIV controllers (HICs) are rare people living with HIV (PLWHs) who naturally control HIV-1 replication and overexpress some cellular restriction factors that negatively regulate the LTR-driven transcription of HIV-1 proviruses.
Objectives: To understand the ability of HICs to control the expression of endogenous retroviruses.
Cortical organoids derived from human induced pluripotent stem cells (hiPSCs) represent a powerful in vitro experimental system to investigate human brain development and disease, often inaccessible to direct experimentation. However, despite steady progress in organoid technology, several limitations remain, including high cost and variability, use of hiPSCs derived from tissues harvested invasively, unexplored three-dimensional (3D) structural features and neuronal connectivity. Here, using a cost-effective and reproducible protocol as well as conventional two-dimensional (2D) immunostaining, we show that cortical organoids generated from hiPSCs obtained by reprogramming stem cells from human exfoliated deciduous teeth (SHED) recapitulate key aspects of human corticogenesis, such as polarized organization of neural progenitor zones with the presence of outer radial glial stem cells, and differentiation of superficial- and deep-layer cortical neurons and glial cells.

Background/objective: This study aims to analyze the effect of whey protein (WP) supplementation on glycemic control, muscle strength, quality of life, and body composition in older adults with non-insulin-dependent diabetes undergoing a resistance training program.
Methods: A double-blind, placebo-controlled, randomized study was carried out with older adults with Type 2 diabetes. Body composition, food intake, muscle strength, glycemic profile, markers of renal function, cardiopulmonary capacity, and quality of life were evaluated.
Despite successful vaccination efforts, the emergence of new SARS-CoV-2 variants poses ongoing challenges to control COVID-19. Understanding humoral responses regarding SARS-CoV-2 infections and their impact is crucial for developing future vaccines that are effective worldwide. Here, we identified 41 immunodominant linear B-cell epitopes in its spike glycoprotein with an SPOT synthesis peptide array probed with a pool of serum from hospitalized COVID-19 patients.

Infection by SARS-CoV-2 is associated with uncontrolled inflammatory response during COVID-19 severe disease, in which monocytes are one of the main sources of pro-inflammatory mediators leading to acute respiratory distress syndrome. Extracellular vesicles (EVs) from different cells play important roles during SARS-CoV-2 infection, but investigations describing the involvement of EVs from primary human monocyte-derived macrophages (MDM) on the regulation of this infection are not available. Here, we describe the effects of EVs released by MDM stimulated with the neuropeptides VIP and PACAP on SARS-CoV-2-infected monocytes.

However, it remains unclear whether subclinical changes in brain metabolism can occur early in the acute phase of the disease. The aim of this study was to identify and quantify changes in brain metabolism in patients hospitalized for acute respiratory syndrome due to COVID-19 with no or mild neurological symptoms.

Previous studies have investigated the effects of different combined training programs involving traditional resistance training and aerobic exercise on hemodynamic parameters and arterial stiffness in older adults. However, little is known about the impact of power training combined with endurance training on these variables in hypertensive older adults. Therefore, this study aimed to investigate the effects of dynamic power training with elastic bands combined with endurance training on arterial stiffness and hemodynamic parameters in hypertensive older adults.
