Dementia Care Research and Psychosocial Factors.

Background: Cognitive training and exercise intervention are suggested for enhancing cognitive functions in people with mild cognitive impairment (MCI). The use of virtual reality (VR) has been applied in cognitive training and exercise intervention in recent decades. However, it is still unclear whether VR-based intervention is a useful means to enhance cognitive functions in people with MCI.

Bidirectional histone monoaminylation dynamics regulate neural rhythmicity.

Histone H3 monoaminylations at Gln5 represent an important family of epigenetic marks in brain that have critical roles in permissive gene expression. We previously demonstrated that serotonylation and dopaminylation of Gln5 of histone H3 (H3Q5ser and H3Q5dop, respectively) are catalysed by transglutaminase 2 (TG2), and alter both local and global chromatin states. Here we found that TG2 additionally functions as an eraser and exchanger of H3 monoaminylations, including H3Q5 histaminylation (H3Q5his), which displays diurnally rhythmic expression in brain and contributes to circadian gene expression and behaviour.

Public Interest in Online Information on Recurrent Urinary Tract Infections Is Greatest for Information with the Poorest Publication Quality.

: Urinary tract infections (UTIs) are among the most prevalent bacterial infections. With many patients turning to the Internet as a health resource, this study seeks to understand public engagement with online resources concerning recurrent UTIs (rUTIs), assess their reliability, and identify common questions/concerns about rUTIs. : Social media analysis tool BuzzSumo was used to calculate online engagement (likes, shares, comments, views) with information on rUTIs.

Rapid degeneration and neurochemical plasticity of the lateral geniculate nucleus following lesions of the primary visual cortex in marmoset monkeys.

Lesions of the primary visual cortex (V1) cause retrograde neuronal degeneration, volume loss and neurochemical changes in the lateral geniculate nucleus (LGN). Here we characterised the timeline of these processes in adult marmoset monkeys, after various recovery times following unilateral V1 lesions. Observations in NeuN-stained sections obtained from animals with short recovery times (2, 3 or 14 days) showed that the volume and neuronal density in the LGN ipsilateral to the lesions were similar to those in the contralateral hemispheres.
