MicroRNA (miR)-212-3p has been identified to exert neuroprotective effects on brain disorders. The current study analyzed the protective role of miR-212-3p in AD rats via regulating the nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3)/Caspase-1 signaling pathway. The AD rat model was established via injection of amyloid-β 1-42 (Aβ1-42), followed by the Morris water maze test. The morphology and functions of neurons were observed. Furthermore, miR-212-3p, NLRP3, cleaved Caspase-1, gasdermin D N-terminus, interleukin (IL)-1β and IL-18 expressions were measured. H19-7 cells were treated with Aβ1-42 to establish the AD cell model, followed by an assessment of cell viability and pyroptosis. Downstream targets of miR-212-3p and specificity protein 1 (SP1), as well as beta-site amyloid precursor protein cleaving enzyme 1 (BACE1) were predicted by databases and testified using dual-luciferase and chromatin immunoprecipitation assays. miR-212-3p was weakly expressed in AD rats. miR-212-3p overexpression was linked to improved learning and memory capacities of AD rats and reduced neuronal pyroptosis linked to neuroinflammation attenuation. In vitro, miR-212-3p improved viability and suppressed pyroptosis of neurons via inhibiting NLRP3/Caspase-1. Overall, miR-212-3p inhibited SP1 expression to block BACE1-induced activation of NLRP3/Caspase-1, thereby attenuating neuroinflammation of AD rats.</p>","PeriodicalId":9147,"journal":{"name":"Bosnian journal of basic medical sciences","volume":" ","pages":"540-552"},"PeriodicalIF":3.4,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9392983/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39787892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present research included 614 UBC samples incorporated in paraffin tissue microarrays, evaluated by immunohistochemistry for NOTCH3 expression.

The samples with negative (0) and weak (1) NOTCH3 immunohistochemical (IHC) score were considered negative, while the samples that showed moderate (2) and strong (3) expression were considered positive. Higher degree of positivity was associated with higher risk of cancer-specific mortality (p<0.001).

The CDC has defined this phenomenon as “long-term symptoms that might be experienced weeks to months after primary infection with SARS-CoV-2, the virus that causes COVID-19 [4]” and proposed designations for this syndrome have included long covid, long chronic covid syndrome, chronic covid, post-COVID-19 syndrome, post-acute covid-19 syndrome and long – haulers [5]. On Feb. 23, 2021, Dr. Francis Collins indicated that the persistent symptoms that occur in patients after recovery from the initial infection could be designated, post-acute sequelae of SARS-CoV-2 (PASC), which we will use in this article. Currently, there is no clear or agreed upon definition or diagnostic criteria for PASC. PASC is most likely a post-infectious illness similar to that reported by patients that had long - term sequelae that persisted for up to 14 months after infection with SARS-CoV-1 or the Middle Eastern respiratory SARS virus (MERS) [6].  \u0000Read more in PDF: https://www.bjbms.org/ojs/index.php/bjbms/article/view/6901/2437","PeriodicalId":9147,"journal":{"name":"Bosnian journal of basic medical sciences","volume":" ","pages":"660-664"},"PeriodicalIF":3.4,"publicationDate":"2022-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9392972/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39787890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to verify all the therapies recommended by the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) from the biochemical point of view. Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit the synthesis of eicosanoids, whereas paracetamol prevents the production of prostaglandin (PG) by interacting with peroxidase (POX) site of the prostaglandin H2 synthase complex. Tramadol is an opioid that has a dual mechanism of action: it binds to the μ-opioid receptor and it inhibits serotonin and adrenaline. Corticosteroids, which are also prescribed for OA pain, inhibit the activity of phospholipase A2 and block the synthesis of arachidonate-derived eicosanoids. Symptomatic slow-acting drugs for osteoarthritis (SYSADOA) are drugs that are well tolerated by patients and help to restore proteoglycan matrix of the cartilage. These drugs include compounds that naturally build articular cartilage. The articular cartilage, as well as the bone located around the cartilage, are destroyed as osteoarthritis progresses. Thus, bisphosphonates, commonly used in the treatment of osteoporosis, were evaluated as potential therapy. However, there is no official recommendation for their use in therapy.

Then, the disease activity index was assessed, including the degree of pathological damage, by HE staining. Subsequently, while Western blotting detected the TLR4/NF-κB pathway and intestinal barrier protein expression (Zonula-1, Occludin, Claudin-1, JAM-A), real-time polymerase chain reaction detected the mRNA expression levels of IRAK1/4 and mucin1/2. Furthermore, the expression levels of Zonula-1 and occludin were detected by immunofluorescence, including the plasma FITC-dextran 4000 concentration, to evaluate intestinal barrier permeability. However, ELISA measured the expression of inflammatory factors to reflect intestinal inflammation in mice. Investigations showed that the IRAK 1/4 inhibitor significantly reduced clinical symptoms and pathological DSS-induced colitis damage in mice and then inhibited the cytoplasmic and nuclear translocation of NF-κB p65, including the phosphorylation of IκBα and reduction in downstream inflammatory factor production.

Several studies have proposed serum microRNAs (miRNAs) as novel biomarkers for diagnosing PTC. In this study, we conducted a meta-analysis aiming to investigate the overall diagnostic accuracy of serum miRNAs in PTC detection. Three online databases including PubMed, EMBASE, and Cochrane Library were searched up to 1 May 2021. We systematically reviewed studies evaluating the value of serum miRNAs in diagnosing PTC, and then summarized the area under receiver operating characteristics curve (AUROC), sensitivity, specificity, and diagnostic odds ratio to assess the accuracy of serum miRNAs for the discrimination between patients with PTC and patients with benign thyroid nodules and healthy controls. We included 32 studies from 6 articles. Overall, there were 463 PTC patients, 334 patients with benign thyroid nodules, and 104 healthy controls. The results showed that the summary sensitivity and specificity were 76% (95% confidence interval [CI]: 68-83%) and 86% (95% CI: 80-91%), respectively, and that the summary AUROC was 0.89 (95% CI: 0.86-0.91), when serum miRNAs were used for discriminating between PTC patients and those with benign nodules. On the other hand, the summary sensitivity and specificity of serum miRNAs for discriminating between PTC patients and healthy controls were 82% (95% CI: 77-86%) and 84% (95% CI: 76-90%), respectively, and the summary AUROC was 0.89 (95% CI: 0.86-0.92).
