Valproic acid (VPA) is a powerful antiepileptic drug that was associated with several neurological and hepatic problems especially with increasing its dose and duration. These problems may be metabolic in origin and related to glucose homeostasis. So, the present study investigated the effect of different doses and durations of VPA on the expression of glucose transporters (Glut1 and Glut4), oxidative stress and inflammatory cytokine (IL-6) in the liver and specific brain regions. Seventy-two male Sprague-Dawley rats were randomly allocated into three equal groups (1) saline group, (2) 200 mg VPA group and (3) 400 mg VPA group. By the end of experiments, the expressions of Glut1, Glut4 nuclear factor erythroid-like 2 related factor (Nrf2), IL-6 and oxidative stress markers [malondialdehyde (MDA) and glutathione (GSH)] in the liver, corpus striatum, prefrontal cortex (PFC) and cerebellum were assessed. We found that administration of VPA (200 mg and 400 mg) caused a significant decrease in the Glut1 and Glut4 expression in different tissues in a dose- and time-dependent manner (P  less then  0.01). Also, VPA (200 and 400 mg) caused a significant increase in MDA with a decrease in GSH in tissues at different times. selleck kinase inhibitor Moreover, VPA (200 and 400 mg) caused significant upregulation in IL-6 expression and downregulation in Nrf2 expression (P  less then  0.01). The results suggest that increasing the dose and time of VPA therapy downregulates Glut1 and Glut4 in the liver and brain which may impair glucose uptake in these tissues. This effect was associated with enhanced oxidative stress, downregulation of nrf2 and upregulation of IL-6 in liver and brain tissues.

This study aimed to investigate the role of lncRNA RP11-390F4.3 in glioblastoma.

The expression levels of RP11-390F4.3, miR-148a and ROCK1 in glioblastoma and nontumor tissues were measured by performing quantitative PCR (qPCR) and data were compared using paired t test. Linear regression analysis was performed to analyze the correlations between RP11-390F4.3 and miR-148a/ROCK1 in glioblastoma tissues. The effects of overexpression of RP11-390F4.3, miR-148a and ROCK1 on U-373 MG cell invasion and migration were analyzed by Transwell assay.

RP11-390F4.3 and ROCK1 were both upregulated in glioblastoma, while miR-148a was downregulated in glioblastoma. In glioblastoma, RP11-390F4.3 was positively correlated with ROCK1 but negatively correlated with miR-148a. In glioblastoma cells, overexpression of RP11-390F4.3 led to upregulated ROCK1 and downregulated miR-148a. Cell invasion and migration analysis showed that overexpression of RP11-390F4.3 and ROCK1 resulted in increased, and overexpression of miR-148a resulted in deceased invasion and migration rates of glioblastoma cells.

Therefore, RP11-390F4.3 may upregulate ROCK1 by downregulating miR-148a to promote glioblastoma cell invasion and migration.

Therefore, RP11-390F4.3 may upregulate ROCK1 by downregulating miR-148a to promote glioblastoma cell invasion and migration.Neuroinflammation has emerged as a key contributor in the pathogenesis of Alzheimer's disease (AD). Mammalian target of rapamycin (mTOR) is a key regulator of metabolism, cell growth and protein synthesis. link2 And an elevated mTOR activity has been detected in AD-affected brain areas. Previous studies have suggested that all-trans retinoic acid (atRA) and rapamycin (RAPA), an mTOR inhibitor, protect lipopolysaccharide (LPS)-induced neuronal inflammation through inhibiting nuclear import of NFκB. The aim of this study was to test the effects of atRA on mTOR expression. Here we discovered that mTOR and p-mTOR expression are elevated in LPS-treated mice or primary rat neurons, while atRA blocks the mTOR gene upregulation via a SIRT1-dependent mechanism. The results of this study demonstrated that atRA may protect LPS-induced neuronal inflammation through suppressing mTOR signaling.Neuroblastoma is a common malignant tumor in children, and patients often have a poor prognosis. Long noncoding RNAs (lncRNAs) are involved in the regulation of neuroblastoma progression. However, the regulatory effect of lncRNA differentiation antagonizing nonprotein coding RNA (DANCR) on neuroblastoma is still not clear. The expression levels of DANCR, miR-338-3p and β-1, 4-galactosyltransferase III (B4GALT3) were determined by quantitative real-time PCR. 3-(4, 5-dimethyl-2 thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide, flow cytometry and transwell assays were used to evaluate the proliferation, apoptosis, migration and invasion abilities of neuroblastoma cells. Moreover, western blot analysis was performed to assess the levels of B4GALT3 and the proliferation, apoptosis and migration-related proteins. Besides, a dual-luciferase reporter assay was used to verify the interactions among DANCR, miR-338-3p and B4GALT3. Mice xenograft models were used to ascertain the effect of DANCR on neuroblastoma tumor growth in vivo. Our results revealed that DANCR was highly expressed in neuroblastoma tissues and cells, and its silencing impeded the progression of neuroblastoma cells. DANCR could interact with miR-338-3p. Knockdown of miR-338-3p recovered the inhibitory effect of DANCR knockdown on neuroblastoma progression. B4GALT3 was a target of miR-338-3p. B4GALT3 overexpression reversed the suppression effect of DANCR silencing on neuroblastoma progression. In-vivo experiments further confirmed that DANCR silencing inhibited neuroblastoma tumor growth. Our results indicated that DANCR promoted B4GALT3 expression to increase the proliferation, migration and invasion of neuroblastoma cells via sponging miR-338-3p, which provided a theoretical basis for the targeted therapy of neuroblastoma.

The novel coronavirus disease (COVID-19) has caused prolonged disruptions in daily life for many communities. Little is known about the impact of the COVID-19 pandemic on the health and well-being of youth with chronic pain and their families. We conducted a longitudinal, mixed-methods study to characterize early adaptation to the COVID-19 pandemic among 250 families of youth (ages 12-21 years) diagnosed with chronic headache (64%) or other chronic pain conditions (36%) and to determine whether direct exposures to COVID-19 and secondary economic stress modified symptom trajectories. Youth and parents reported on pain interference, anxiety, depression, and insomnia symptoms at 4 waves of data collection from April 2020 to July 2020. We also collected qualitative data on the impact of the pandemic on the youth's pain problem. Nearly half of our sample (49.6%) experienced direct exposures to COVID-19. Secondary economic stress was also common, affecting 44.4% of families. Symptom trajectories for pain, insomnit exposures to COVID-19 did not modify symptom trajectories. However, youth pain interference and parent insomnia worsened in families who experienced secondary economic stress. Qualitative data revealed perceived benefits and harms from school closures on the youth's pain problem. Our findings of high symptom burden suggest that pediatric pain clinicians should offer distance assessment and treatment (eg, through telemedicine) to avoid pandemic-related disruptions in pain care.

Poor access to pediatric chronic pain care is a longstanding concern. The COVID-19 pandemic has necessitated virtual care delivery at an unprecedented pace and scale. We conducted a scoping review to create an interactive Evidence and Gap Map of virtual care solutions across a stepped care continuum (ie, from self-directed to specialist care) for youth with chronic pain and their families. Review methodology was codesigned with 8 youth with chronic pain and 7 parents/caregivers. Data sources included peer-reviewed scientific literature, gray literature (app stores and web sites), and a call for innovations. Records were independently coded and assessed for quality. Overall, 185 records were included (105 scientific records, 56 apps, 16 web sites, and 8 innovations). Most virtual care solutions were applicable across pediatric chronic pain diagnoses, with the greatest proportion at lower levels of stepped care (ie, >100 self-guided apps and web sites). Virtual delivery of psychological strategies was commth health records, communication with health professionals, web accessibility, and content addressing social/family support, medications, school, substance use, sleep, diet, and acute pain flares or crises. Evidence and Gap Maps are a novel visual knowledge synthesis tool, which enable rapid evidence-informed decision-making by patients and families, health professionals, and policymakers. This evidence and gap map identified high-quality virtual care solutions for immediate scale and spread and areas with no evidence in need of prioritization. Virtual care should address priorities identified by youth with chronic pain and their families.

The etiology of central nervous system infections is often difficult to establish. link3 FilmArray meningitis/encephalitis (ME) panel is a multiplex polymerase chain reaction for rapid identification of 14 pathogens. The aim of this study was to evaluate potential real-life contributions of the use of this method in the pediatric population.

We herein report the results obtained with FilmArray ME in a retrospective case series of 367 children with suspected central nervous system infection. We identified viral and bacterial agents by FilmArray, and we evaluated the potential diagnostic contributions of the use of the panel taking into account the cytological, biochemical, and microbiological results of the cerebrospinal fluid (CSF) analysis.

The FilmArray ME panel detected a viral infection in 186 cases (50.7%) and a bacterial infection in 12 cases (3.3%). Fifty-three cases (28.4%) of viral infection had at least 1 CSF finding that could be mistaken for bacterial meningitis. Enterovirus was identified in 2 cases with normal CSF findings. Among 12 bacterial infection cases, only 6 (50%) had a positive result with conventional microbiology analysis (Gram stain and culture). The CSF findings suggestive of bacterial meningitis were found in all 6 cases in which FilmArray was the only method to identify bacterial etiological agent.

FilmArray ME panel identified an etiological agent in cases in which conventional CSF analysis failed, providing potential clinical contributions to the management of such cases.

This study aimed to assess the effect that race and socioeconomic factors have on the provision of care to cervical cancer patients based on National Comprehensive Cancer Network (NCCN) recommended treatment guidelines.

To do this, we completed a retrospective cohort study using the American College of Surgeon's Nation Cancer Database from 2004 to 2016. We identified all reported cases of cervical cancer in that period. Two cohorts were created using self-reported racial demographic data, Hispanic- and White, non-Hispanic-identified patients. Our primary outcome variables were adherence to NCCN-recommended treatment and 5-year overall survival. Adherence to NCCN-recommended treatment was determined by the provision of surgical and/or radiation and/or chemotherapy treatment based on the clinical stage at time of diagnosis and the presence or absence of lymphovascular space invasion. We used bivariate analyses to compare baseline characteristics between the 2 cohorts, multivariable logistic regression to identify independent predictors of 5-year survival, and Cox proportional hazards models to compute survival by group.
