Reduced-step amalgamated polishing programs - a new defacto standard?
Immersion rod is a very low-cost electrical device. It is based on simple working principle and widely used in developing nations to heat water for various domestic needs. However, the literature about electrocution caused by it is nearly absent. This is despite its usage being potentially hazardous, with almost sure fatal outcome in cases of mishandling. Data was gathered from 2011 to 2020, via inquest and autopsy reports, regarding electrocution deaths related to it. 6 cases were identified. All consisted of females in domestic settings, as the unique epidemiology in stark contrast to the existing literature on electrocution fatalities worldwide. Injury patterns in a few cases resembled those typical of high voltage electrocution, in these low voltage fatalities. Characteristics of joule burns showed sub-patterns, deviant from electrocution related to other appliances and was again unreported previously. Spark burns and scalds were patterns, quite diagnostic of immersion rod fatalities. A typical pattern for a multitude of injuries in each case is brevity of this study. Injury patterns are presented as a classical guide for further growth of the literature on these types of fatalities.Autophagy plays an essential role in modulating asthma progression. MiR-20a-5p can regulate autophagy, but its effects on allergic asthma are still unclear. The aim of this study was to explore the potential of miR-20a-5p on autophagy-modulated airway remodeling and to reveal the underlying molecular mechanisms. We found that miR-20a-5p expression was markedly down-regulated in lung of ovalbumin (OVA)-induced mouse model with allergic asthma and in cells stimulated by OVA. Meanwhile, autophagy, apoptosis, fibrosis and inflammatory response were detected in pulmonary tissues from OVA-treated mice. Importantly, luciferase assays showed that ATG7 was a target of miR-20a-5p. www.selleckchem.com/Proteasome.html We also found that miR-20a-5p over-expression markedly reduced ATG7, while its inhibition promoted ATG7 in cells. In addition, over-expressing miR-20a-5p in OVA-treated cells significantly decreased ATG7 expression levels, along with markedly reduced autophagy, apoptotic cell death, fibrosis and inflammatory response. These results were similar to the effects of autophagy inhibitor 3-Methyladenine (3-MA), indicating that miR-20a-5p was involved in autophagy-induced apoptosis, fibrosis and inflammation. In vivo experiments further demonstrated that miR-20a-5p over-expression was associated with ATG7 reduction in parallel with the alleviated airway remodeling in OVA-treated mice also through suppressing collagen accumulation, apoptosis and inflammation. Similarly, animal studies further confirmed that miR-20a-5p functioned as an autophagy inhibitor to mitigate allergic asthma development. Therefore, miR-20a-5p may be a promising biomarker and therapeutic target during asthma progression by regulating ATG7-modulated autophagy.
Osteoarthritis (OA) is characterized by chondrocyte injury and dysfunction, such as excessive apoptosis, inflammatory response and extracellular matrix (ECM) degradation. Circular RNA (circRNA) deregulation is reported to be involved in OA. Our study aimed to explore the role of circ_0134111 in OA.

Human chondrocytes were treated with interleukin-1β (IL-1β) to mimic OA cell model. The expression of circ_0134111, miR-515-5p and suppressor of cytokine signaling 1 (SOCS1) mRNA was measured by real-time quantitative polymerase chain reaction (RT-qPCR), and the protein levels of SOCS1 and apoptosis-/inflammation-/ECM-related markers were determined by western blot. Cell proliferation and cell apoptosis were assessed using cell counting kit-8 (CCK-8) and flow cytometry assay, respectively. For mechanism analysis, the predicted interaction between miR-515-5p and circ_0134111 or SOCS1 was verified by dual-luciferase reporter assay, pull-down assay and RNA immunoprecipitation (RIP) assay. Rescue experiments were plammatory responses and ECM degradation in OA cell model by mediating the miR-515-5p-SOCS1 network, hinting that circ_0134111 was involved in OA progression.A group of patients with adult-type soft tissue sarcoma is at high risk of local recurrence and distant metastases. Age, tumour site, histological subtype, tumour size and grade have been identified as the most important independent adverse prognostic factors. Macroscopically complete tumour resection is considered as the mainstay of treatment with the addition of preoperative or postoperative radiotherapy for extremity or trunk localisation. Retroperitoneal localisation requires compartmental resection and is associated with a worse prognosis. Here, radiotherapy is of no proven value. Perioperative chemotherapy is considered to treat micrometastatic disease not detectable at the time of diagnosis. The neoadjuvant application gives the risk of distant metastasis the greatest importance as therapy is carried out at the earliest possible time, whereas adjuvant chemotherapy is delayed by surgery and the necessary wound healing. With reported response rates up to 30%, both the operability may be improved and the risk of intraoperative tumour cell dissemination may be reduced, resulting also in reduced local relapse rates. However, the potential risk of early tumour progression may counteract this benefit. Optimised strategies with multimodality approaches including chemotherapy, regional hyperthermia (RHT) and immunotherapeutic agents have been shown to improve survival in high-risk patients. Here, we focus on the data from available randomised studies investigating the use of perioperative chemotherapy in patients with high-risk adult-type soft tissue sarcoma, including the use of RHT for local enhancement of chemotherapy effect and immune induction.The anti-citrillinated protein antibody (ACPA) plays an important role in early diagnosis of rheumatoid arthritis (RA), and is usually detected by using cyclic citrullinated peptide (CCP) as antigen. The ACPA against CCP test is usually performed utilizing enzyme-linked immunosorbent assay (ELISA), but the ELISA is expensive and time-consuming. Here, latex particle-enhanced turbidimetric immunoassay (LTIA) based on CCP-immobilized latex bead was proposed for fast measurements of ACPA of RA patients. CCP-immobilized latex bead was fabricated through three methods, including direct coupling, overall coupling and layer by layer coupling. According to the optimized experiments, layer-by-layer coupling was the best method with advantages of time-saving, simple operation and good repeatability. In addition, a spacer arm of appropriate length between latex beads and CCP could avoid stereoscopic obstacles and make ACPA closer to CCP. The CCP-immobilized latex bead based on layer by layer coupling (CCP-LB-LLC) was used for assembling the homemade kit, which was applied in fast measurements of ACPA through LTIA.
