Apelin‑13 improved autophagy‑mediated microglia polarization towards M2 phenotype to alleviate inflammatory response in LPS‑stimulated cells. Autophagy flux inhibitor chloroquine antagonized these effects of apelin‑13 on LPS‑stimulated cells. Besides, apelin‑13 decreased the enrichment of H3K9ac at the promoter region of TNF‑α and IL‑6 to inhibit inflammatory response, which was reversed by histone deacetylase antagonist valproate. Taken together, apelin‑13 alleviated inflammation via facilitating microglia M2 polarization due to autophagy promotion, and inhibiting H3K9ac enrichment on promoter regions of TNF‑α and IL‑6.Reactive gliosis and inflammation are risk factors for white matter injury (WMI) development, which are correlated with the development of many neurodevelopmental deficits with no treatment. This study aimed to understand the mechanisms correlated with WMI, with a particular focus on the role of nuclear factor‑kappa B (NF‑kB) and p38 mitogen‑activated protein kinases (MAPKs) pathways. Seven‑day‑old Wistar rats were used to generate cerebellar tissue slices. Slices were cultured and randomly allocated to one of 3 groups and treated as follows group‑I (control); group‑II (WMI), slices were subjected to 20 min of oxygen‑glucose deprivation (OGD); group‑III (WMI+ blockers), slices were subjected to OGD and treated with the blockers. Results showed that OGD insult triggered a marked increase in the apoptosis among WM elements, as confirmed by TUNEL assay. Immunocytochemical experiments revealed that there was a significant decrease in the percent of MBP+ OLs and NG2+ OPCs, and myelin integrity. There was also a significant increase in the percent of reactive microglia and astrocytes. BrdU immunostaining revealed there was an increase in the percent of proliferating microglia and astrocytes. Q‑RT‑PCR results showed OGD upregulated the expression levels of cytokines (TNF‑α, IL‑1, IL‑6, and IL‑1β) and inducible nitric oxide synthase (iNOS). On the other hand, treatment with BAY11 or SB203580 significantly enhanced the OL survival, restored myelin loss, and reduced microglia and astrocyte reactivity, and downregulated the iNOS and cytokine expression. Our findings demonstrate that blocking of NF‑KB/p38 MAPK pathways alleviated reactive gliosis, inflammation, and OL loss upon WMI. The findings may help to develop therapeutic interventions for WMI.Hyperserotonemia, during the early developmental phase, generates behavioral and biochemical phenotypes associated with autism spectrum disorder (ASD) in rats. Phosphodiesterase‑1 (PDE1) inhibitors are known to provide benefits in various brain conditions. We investigated the role of a selective PDE1 inhibitor, vinpocetine on ASD‑related behavioral phenotypes (social behavioral deficits, repetitive behavior, anxiety, and hyperlocomotion) in a developmental hyperserotonemia (DHS) rat model. Also, effects on biochemical markers related with neuronal function brain derived neurotrophic factor (BDNF) and phosphorylated cAMP response element binding protein (pCREB), inflammation interleukins (IL‑6 and IL‑10) and tumor necrosis factor-alpha (TNF‑α), and oxidative stress (TBARS and GSH) were studied in important brain areas (frontal cortex, cerebellum, hippocampus, and striatum). Administration of 5‑methoxytryptamine (5‑MT) to rats prenatally (gestational day 12) and in early developmental stages postnatal day (PND 0 - PND 20), resulted in impaired behavior and brain biochemistry. Administration of vinpocetine daily (10 and 20 mg/kg) to 5‑MT rats from PND 21 to PND 48 resulted in an improvement of behavioral deficits. Also, vinpocetine administration significantly increased the levels of BDNF, ratio of pCREB/ CREB, IL‑10, and GSH, and significantly decreased TNF‑α, IL‑6, and TBARS levels in different brain areas. Finally, our correlation analysis indicated that behavioral outcomes were significantly associated with the biochemical outcome. Vinpocetine, a selective PDE1 inhibitor, rectified important behavioral phenotypes related with ASD, possibly by improving markers of neuronal function, brain inflammation, and brain oxidative stress. Thus, PDE1 could be a potential target for pharmacological interventions and furthering our understanding of ASD pathogenesis.Sertoli cells (SCs) may be a new candidate to decrease ischemic damage due to their ability to secrete factors that actively protect neurons and inhibit uncontrollable immune responses. Pre‑treatment with these cells was considered in the current study. SCs were injected into the right striatum in rats using the stereotaxic technique. Ten days after injection, middle cerebral artery occlusion surgery was performed. Following these procedures, neurological deficit scores, brain edema, blood‑brain barrier integrity, infarct volume, and the expression of apoptotic factors in the cortex, striatum, and piriform cortex‑amygdala were evaluated. Analysis showed that behavioral deficits, infarct volume, blood‑brain barrier permeability, and edema in the striatal area in the allograft group demonstrated a significant decrease compared to the control group. Additionally, analysis of the expression of caspase‑3 and Bcl‑2 proteins in the striatum indicated a remarkable reduction and increase, respectively, in the allograft group compared to the control group. According to the obtained results, one possible mechanism for the neuroprotection induced by SCs in an ischemic brain is the reduction of apoptotic factors.Cerebral ischemic stroke (CIS) is a significant cause of disability and death. Inflammation usually occurs after CIS and accelerates cellular damage. NLRP3 plays a key role in the formation of CIS‑associated inflammasome. Understanding how NLRP3 is regulated bears great importance. We hypothesized that lncRNA NEAT1 can downregulate NLRP3 expression by regulating the miR‑10b‑5p/BCL6 axis, and thus regulate microglia‑driven inflammation. The expression of NEAT1 was analyzed in CIS patients and an in vitro model of oxygen and glucose deprivation/re‑oxygenation (OGD/R). We assessed the levels of pro‑inflammatory cytokines IL‑18 and IL‑1β with ELISA. Interactions between NEAT1/miR‑10b‑5p and miR‑10b‑5p/BCL6 were determined by luciferase assay. The interaction of BCL6 and NLRP3 was identified by ChIP; RNA, and protein levels were evaluated by qRT‑PCR and western blot, respectively. We found that NEAT1 level was decreased in CIS patients and OGD/R treated cells. OGD/R exerted pro‑inflammasome effects by increasing the expression of inflammasome‑associated proteins and ROS and malondialdehyde (MDA) while inhibiting SOD production. This effect was partially antagonized by NEAT1. We bioinformatically identified interactions between NEAT1/miR‑10b‑5p, BCL6/miR‑10b‑5p, and NLRP3‑promoter/BCL6, and validated them by luciferase assay, qRT‑PCR, and ChIP. NEAT1 inhibited miR‑10b‑5p and upregulated BCL6 by ceRNA mechanism and alleviated OGD/R induced cell damage. We also proved that BCL6 was a repressive transcription factor in the regulation of NLRP3 expression. Thus, lncRNA NEAT1 inhibited inflammasome activation by NLRP3 in microglia via the NEAT1/ miR‑10b‑5p/BCL6/NLRP3 regulatory axis, which alleviated deleterious outcomes of ischemic stroke.Cerebral palsy (CP) is associated with the non‑progressive damage of upper motor neurons, which is manifested by a variety of symptoms, particularly motor and functional deficits. During the rehabilitation of patients with CP, attention is paid to improving mobility which can have a significant impact on the child's development. The effectiveness of rehabilitation depends on the plasticity of the nervous system, which may be genetically determined. Of importance are the various polymorphisms of the brain derived neurotrophic factor (BDNF) gene. It has been shown that the Val/Val genotype may predispose children to greater improvements in function and its maintenance. However, subjects with the Met allele showed a reduced tendency to improve their motor functions but had significantly better results on indirect tests assessing gait function. Fifty subjects with CP participated in this study. They were divided into two groups by genotype and examined on their rehabilitation progress in terms of improved gait function. The results correlated with other studies describing the relationship between the BDNF genotype and learning motor functions in CP, and with numerous studies on the relationship between BDNF genotype and neuroplasticity in stroke patients. This research provides a basis for the identification of genetic biomarkers in patients with CP which can be used to predict the effects of rehabilitation therapy and help with the development of personalized treatments.
Septic cavernous sinus thrombosis (SCST) is a rare but life-threatening condition that commonly arises from infections, including paranasal sinusitis, otitis media, and skin infection. Meanwhile, head trauma as a predisposing factor of SCST has been scarcely reported. We report a case of SCST complicated by meningitis after minor head trauma, even in the absence of identifiable fractures.

A 77-year-old female presented with diplopia combined with ocular pain and headache lasting a week. She had a recent blunt head trauma 2 weeks before the diplopia onset. The trauma was not accompanied by identifiable skull fractures, bleeding, or loss of consciousness. Neurological examination revealed incomplete ptosis, eyelid swelling, and medial and vertical gaze limitations of both eyes. Gadolinium-enhanced brain magnetic resonance imaging demonstrated multifocal thrombotic filling defects, including those of the cavernous sinus, sinusitis involving the sphenoid and ethmoid sinuses, and otomastoiditis. The cerebrospit possible cause of SCST. Early recognition and prompt treatment are essential for improving outcomes. Moreover, close observation is warranted, even if apparent serious complications were absent during initial evaluations in minor head trauma.
Percutaneous drainage catheters (PDCs) are required for the management of benign biliary strictures refractory to first-line endoscopic treatment. While biliary patency after PDC placement exceeds 75%, long-term catheterization is occasionally necessary. In this article, we assess the outcomes of patients at our institution who required long-term PDC placement.A single-institution retrospective analysis was performed on patients who required a PDC for 10 years or longer for the management of a benign biliary stricture. The primary outcome was uncomplicated drain management without infection or complication. Drain replacement was performed every 4 to 12 weeks as an outpatient procedure.Nine patients (three males and six females; age range of 48-96 years) required a long-term PDC; eight patients required the long-term PDC for an anastomotic stricture and one for iatrogenic bile duct stenosis. LLY-283 purchase A long-term PDC was required for residual stenosis or patient refusal. Drain placement ranged from 157 to 408 months. nts (three males and six females; age range of 48-96 years) required a long-term PDC; eight patients required the long-term PDC for an anastomotic stricture and one for iatrogenic bile duct stenosis. A long-term PDC was required for residual stenosis or patient refusal. Drain placement ranged from 157 to 408 months. In seven patients, intrahepatic stones developed, while in one patient each, intrahepatic cholangiocarcinoma or hepatocellular carcinoma occurred.Long-term PDC has a high rate of complications; therefore, to avoid the need for using long-term placement, careful observation or early surgical interventions are required.
