Objective: To report the experience of adapting the stomatherapy service during the COVID-19 pandemic.

Method: Experience report related to adaptations in the work routine in times of COVID-19 pandemic, from March to May 2020, in a specialized stomatherapy center in a city in the South of Brazil.

Results: The work routines were adapted to suit the protection measures for workers and users who used stomatherapy services.

Myotonic dystrophy type 1 (DM1) is an RNA-based disease with no current treatment. It is caused by a transcribed CTG repeat expansion within the 3' untranslated region of the dystrophia myotonica protein kinase () gene. Mutant repeat expansion transcripts remain in the nuclei of patients' cells, forming distinct microscopically detectable foci that contribute substantially to the pathophysiology of the condition.

Systemic inflammation enhances the risk and progression of Alzheimer's disease (AD). Lipopolysaccharide (LPS), a potent pro-inflammatory endotoxin produced by the gut, is found in excess levels in AD where it associates with neurological hallmarks of pathology. Sex differences in susceptibility to inflammation and AD progression have been reported, but how this impacts on LPS responses remains under investigated.

Neuroinflammation plays an important role in the pathogenesis of a range of brain disorders. Non-invasive imaging of neuroinflammation is critical to help improve our understanding of the underlying disease mechanisms, monitor therapies and guide drug development. Generally, MRI lacks specificity to molecular imaging biomarkers, but molecular MR imaging based on chemical exchange saturation transfer (CEST) can potentially detect changes of myoinositol, a putative glial marker that may index neuroinflammation.

Background: Soccer is considered the most popular sport in the world concerning both audience and athlete participation, and the incidence of ACL injury in this sport is high. The understanding of injury situations and mechanisms could be useful as substratum for preventive actions.

Purpose: To conduct a video analysis evaluating the situations and mechanisms of ACL injury in a homogeneous population of professional male soccer players, through a search entirely performed on the YouTube.

Segmentation and analysis of histological images provides a valuable tool to gain insight into the biology and function of microglial cells in health and disease. Common image segmentation methods are not suitable for inhomogeneous histology image analysis and accurate classification of microglial activation states has remained a challenge. In this paper, we introduce an automated image analysis framework capable of efficiently segmenting microglial cells from histology images and analyzing their morphology.

Article Synopsis
  • Microglia activation is a significant factor in Alzheimer's disease development, and metabolite levels measured by magnetic resonance spectroscopy (MRS) can indicate neuroinflammation, though their relationship to microglial activation is not fully understood.
  • In a study using MRS on both healthy mice and transgenic mice with Alzheimer's (APP/PS1), it was noted that healthy mice showed increased lipid and macromolecule levels after microglial activation, while Alzheimer’s mice did not exhibit the same response to lipopolysaccharides (LPS).
  • The research suggests that changes in fatty substances (ML9) could indicate healthy microglial activation, whereas myoinositol (mI) reveals different metabolic responses in Alzheimer’s models
