To systematically review and examine the current literature regarding the effects of Virtual Reality (VR)-based rehabilitation on neural plasticity changes in stroke survivors.

Six bioscience and engineering databases were searched, including Medline via Ebsco, Embase, PsycINFO, IEEE Explore, Cumulative Index of Nursing and Allied Health, and Scopus.

Studies reporting on the pre-post assessment of a VR intervention with neural plasticity measures published between 2000-2021 were included.

Two independent reviewers conducted study selection, data extraction and quality assessment. Methodological quality of controlled trials was assessed using the Physiotherapy Evidence Database scale. Risk of bias of pre-post intervention and case studies was evaluated using the National Institutes of Health Quality Assessment Tool.

Twenty-seven studies (Total n=232) were included. Seven randomized controlled trials were rated as good quality while the two clinical controlled trials were moderate. Based on the risk ond application in stroke rehabilitation.
Virtual reality induced changes in neural plasticity for stroke survivors. Positive correlations between the neural plasticity changes and functional recovery elucidates the mechanisms of VR's therapeutic effects in stroke rehabilitation. This review prompts systematic understanding of the neurophysiological mechanisms of VR-based stroke rehabilitation and summarizes the emerging evidence for ongoing innovation of VR systems and application in stroke rehabilitation.
Subcortical ischemic stroke usually leads to the geometric microstructural changes in the orientation of peri-infarct white matter fiber. We conducted the study to determine the microstructural changes in the white matter fiber orientation in post stroke patients with and without cognitive impairment (PSCI, NPSCI), and to investigate the impact of peri-infarct white matter damage on the morphology and functional connectivity of their projective cerebral regions.

A novel mathematical framework called Director Field Analysis (DFA) was applied to study the microstructural changes in the orientation of white matter fiber in PSCI (n=23), NPSCI (n=17), and cognitively normal (CN, n=29) individuals.

PSCI patients had extensive abnormalities in the orientation of white matter fiber in the corpus callosum, bilateral internal capsule, external capsule, forceps major, forceps minor, and corticospinal tract in comparison with NPSCI and CN. NPSCI patients also showed significant increases in bend and twist of white .
Post-stroke patients experienced pathological damage in the orientation of peri-infarct white matter fiber. The peri-infarct white matter damage may further induce the abnormal functional connectivity in projective cerebral regions. These degenerations of peri-infarct white matter fiber and associated functional connectivity changes may mediate the cognitive impairment in post-stroke.The histologic differences in Schlemm's canal (SC) and trabecular meshwork (TM), obtained from the trabeculectomy specimens of different age-group glaucoma patients, were compared. This study involved 44 trabeculectomy specimens of 37 juvenile-onset open-angle glaucoma (JOAG) patients (Group A) and 24 trabeculectomy specimens of 24 elderly-onset primary OAG (POAG) patients (age range 70-79 years, Group B) with no familial history of POAG. Clinical parameters of gender, maximum intraocular pressure (IOP), and the number of glaucoma medications used prior to trabeculectomy were investigated and compared between the two groups. From light microscopy photographs of hematoxylin-eosin, and immunohistochemical staining of markers for SC endothelium (SCE), the total SC length (TSC), comprised of the opened-SC length (OSC) and the closed-SC length (CSC), the percentage of CSC in TSC (%CSC), the percentage of positive SCE marker in CSC (%PinCSC), and the percentage of negative SCE marker in OSC (%NinOSC) were analyzed.) in Group A and Group B, respectively. Akt inhibitor The platelets appeared to repair the SCE damage for maintaining the blood aqueous barrier in both groups of POAG eyes. Smaller SC diameters and accompanying TM abnormality were features observed in the young-onset JOAG patients, thus suggesting developmental abnormalities in the outflow routes. The collapse of SC lumen, presumably due to aging, was the feature observed in the elderly-onset POAG patients. In Group A, the significantly higher IOP, despite of no significant number of topical medications used prior to trabeculectomy, also suggested that JOAG eyes can be categorized as a distinct type of POAG from the eyes of elder-aged POAG patients. link2 The SCE drop out observed in the glaucomatous eyes of the different age groups suggested that worsening of IOP control may possibly occur equally in both groups.
To evaluate the role of Toll-like receptor 2 (TLR2) signaling in retinal neovascularization in a mouse model of oxygen-induced retinopathy (OIR).

The OIR model was established in C57BL/6J wild type (WT) mice and TLR2
mice. Retinal neovascularization in the OIR model was measured by counting new vascular cell nuclei above the internal limiting membrane and analyzing flat-mounted retinas perfused with fluorescein dextran and immunostained with Griffonia Simplicifolia (GS) isolectin. The expression of TLR2 and VEGF in the retina was detected by immunofluorescence. Expression of TGF- β1, b-FGF, and IL-6 mRNA in the retina was measured by quantitative real-time PCR.

Compared to WT OIR mice, retinal neovascularization was attenuated in TLR2
OIR mice. The co-expressions of TLR2 and VEGF were remarkably and consistently increased in WT OIR mice; however, there was no expression of TLR2 and a significant decrease in VEGF expression in TLR2
OIR mice. These results suggest that TLR2 plays a central role in OIR model angiogenesis. Expression of TGF- β1, b-FGF, and IL-6 mRNA were reduced in the TLR2
OIR mice, suggesting that the inflammatory response induced by TLR2 relates to angiogenesis.

TLR2 signaling in the retina is associated with neovascularization in mice. Inflammation contributes to the activation of angiogenesis and is partially mediated through the TLR2-VEGF retinal signaling pathway.

Here, we investigate the clinical relevance of circulating CD4 Th1 response against telomerase (anti-TERT Th1 response) in melanoma patients. The spontaneous anti-TERT Th1 response was detected in 54.5% (85/156) of melanoma patients before treatment. The prevalence of this systemic response was inversely related to Breslow thickness above 1mm and AJCC stage ≥ II (P = 0.001 and 0.032). In contrast to patients treated by targeted therapies, the anti-TERT Th1 immunity was associated with objective response after immune checkpoint inhibitors (ICI) treatment. Hence 86% (18/21) of responder patients exhibited pre-existing anti-TERT Th1 versus 35% (6/19) in non-responders (P = 0.001). This response was also associated with increased progression free survival and overall survival in melanoma patients treated with ICI (P = 0.0008 and 0.012 respectively). link3 Collectively, the presence of circulating anti-TERT Th1 response is inversely related to melanoma evolution and appears to be a predictive factor of response to immunotherapy. Our results highlight the interest of telomerase-specific CD4 Th1 response as a promising blood based biomarker of immune checkpoint inhibitors therapy in melanoma.Dominant and recessive mutations in the desmosomal cadherin, desmoglein-1 (DSG1), cause the skin diseases palmoplantar keratoderma (PPK) and severe dermatitis, multiple allergies, and metabolic wasting (SAM) syndrome, respectively. Here, we compare two dominant missense mutations in the DSG1 transmembrane domain (TMD), G557R and G562R, causing PPK (DSG1PPK-TMD) and SAM syndrome (DSG1SAM-TMD), respectively, to determine the differing pathomechanisms of these mutants. Expressing the DSG1TMD mutants in a DSG-null background, we use cellular and biochemical assays to reveal differences in the mechanistic behavior of each mutant. Super resolution microscopy and functional assays showed a failure by both mutants to assemble desmosomes due to reduced membrane trafficking and lipid raft targeting. DSG1SAM-TMD maintained normal expression levels and turnover relative to DSG1WT, but DSG1PPK-TMD lacked stability, leading to increased turnover through lysosomal and proteasomal pathways and reduced expression levels. These results differentiate the underlying pathomechanisms of these disorders, suggesting that DSG1SAM-TMD acts dominant negatively while DSG1PPK-TMD is a loss-of-function mutation causing the milder PPK disease phenotype. These mutants portray the importance of the DSG TMD in desmosome function and suggest that a greater understanding of the desmosomal cadherin TMDs will further our understanding of the role that desmosomes play in epidermal pathophysiology.Increased presence of IL-22+ cells in the skin is a characteristic finding in skin barrier defects, such as psoriasis and atopic dermatitis. However, mechanistic insight into effects of IL-22 on epidermal functioning is yet to be elucidated. One crucial step during epidermal differentiation is deimination or citrullination. Here, we show reduced levels of peptidylarginine deiminase 1, an enzyme that converts peptidylarginine into citrulline in lesional psoriatic skin. IL-22 signaling through the IL-22 receptor complex was found to suppress expression of peptidylarginine deiminase 1 in epidermal keratinocytes. Subsequently, total peptidylarginine deiminase activity and extent of protein deimination in keratinocytes treated with IL-22 were reduced together with a significant decrease in deimination of keratin 1 and FLG, both important for epidermal differentiation. Vitamin D and acitretin partly restored the peptidylarginine deiminase 1 defect caused by IL-22. Collectively, we show that IL-22 downregulates deimination, thus identifying a potential target for treatment of skin barrier defects.Psychometric validity and reliability of widely used atopic dermatitis (AD) outcome measures across different race and ethnicity is unclear. We describe rates of reporting race, ethnicity and skin tone in studies testing psychometric properties of AD outcome measures and compare psychometric analyses across race, ethnicity, and skin tone. We systematically reviewed MEDLINE and EMBASE for studies reporting psychometric properties of clinician reported (ClinROM) or patient reported outcome measures (PROM) in AD (PROSPERO CRD42021239614). Overall, 16,100 non-duplicate articles were screened; 165 met inclusion criteria. Race and/or ethnicity were reported in 55 (33.3%) studies; of those, race was assessed by self-report in 10 (6.1%) or was unspecified in 45 (27.3%). Sixteen studies (9.7%) evaluated psychometric property differences by race and only 5 (4.4%) of those that did not recognized it as a limitation. Properties assessed across race, ethnicity or skin tone were differential item functioning, convergent validity feasibility, inter-rater reliability, intra-rater reliability, test-retest reliability, and known-groups validity.
