Antibiotic contamination has already been one of hazards to aquatic environment due to the abuse of antibiotics. Metal-organic frameworks (MOFs) are known as a kind of promising porous material for solving the environmental deterioration. In this article, the physicochemical and electrochemical properties of a series of porous copper oxide carbon materials (CuOx-C) synthesized by carbonizing Cu-BTC were compared. Due to the suitable carbonization temperature, CuOx-C-550 N, whose geometric structure was similar to Cu-BTC, possessed a multiscale pore structure containing many mesopores and partial macropores in accordance with the pore size distribution curves. More copper/copper oxides were introduced toimproving the electrochemical ability, evidence by XRD, XPS, CV and EIS characterization. Moreover, the degradation of ceftazidime (CAZ) through anodic oxidation was discussed. In AO/CuOx-C-550 N system, the effects of current, solution pH, initial CAZ concentration and Na2SO4 concentration were analyzed. CAZ removal rate reached 100% within 20 min under the optimal condition and a good electrocatalytic ability with 90% CAZ removal after 20 runs indicated a good electrochemical stability of CuOx-C-550 N. Furthermore, the degradation mechanism and pathway of CAZ were proposed. The Cu(II)/Cu(I) oxidation-reduction couples on the anodic surface contribute to the efficiently selective degradation of cephalosporins for CuOx-C-550 N. Overall, this study shows a good method to design and prepare a new MOF derivative for the remediation of aquatic contamination.Currently, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) were approved for the treatment of non-small cell lung cancer (NSCLC) patients harboring EGFR mutation. However, some lung cancer patients fail to respond and eventually develop drug resistance. Therefore, new therapeutic strategies are needed to improve the outcomes for substantial clinical benefit. Here we aimed to explore the combination of vinorelbine with the second EGFR-TKI afatinib in NSCLC cells with or without EGFR mutation. The three cells of H1975, HCC827, and H460 were assessed for the combination of vinorelbine and afatinib. Vinorelbine combined with afatinib synergistically inhibited the three lung cancer cells growth without aggravating adverse effect on the normal lung cells. The combination of low doses of vinorelbine and afatinib suppressed the cancer cell proliferation by cell colony formation assay and significantly induced cell apoptosis. The anti-apoptotic proteins Bcl-xL and Bcl-2 showed significant reduction after the drug combination treatment, while the pro-apoptotic protein Bax as well as apoptosis indicators cytochrome C and cleaved PARP were observed a notable increasing. EGFR downstream pathways including AKT, ERK, JNK, and p38 were highly active and p53 was inactive in the three lung cancer cells, favoring tumor growth. The low doses of vinorelbine plus afatinib blocked the phosphorylation of AKT, ERK, JNK, and p38, but restored the expression of p53. Our findings suggested that the combination of vinorelbine and afatinib could be recommended as a therapeutic regimen for treatment of NSCLC with or without EGFR mutation. This study aimed to clarify the association between types of knee arthroplasty (KA) (total knee arthroplasty (TKA) or unicompatmental knee arthroplasty (UKA)) and surgical site infection (SSI) with adjustment for various factors, using a Japanese national database. Data on 181,608 patients who underwent unilateral primary KA for osteoarthritis from 2010 to 2017 were obtained from the Japanese Diagnosis Procedure Combination database. https://www.selleckchem.com/products/cl-amidine.html SSI was identified based on International Classification of Diseases 10th Revision codes. Deep SSI (i.e. periprosthetic joint infection (PJI)) was identified as SSI treated with surgical procedures. Multivariable logistic regression analyses for SSI and PJI were performed, in which dependent variables included types of KA, patient backgrounds (sex, age, body mass index (BMI), smoking status, comorbidities), and seasonality. Eight percent of analyzed patients underwent UKA, while 92% underwent TKA. The proportions of SSI and PJI after UKA were 0.9% and 0.3%, respectively, both of which were lower than those after TKA (1.9% and 0.6%) (P<0.001). Multivariable analyses showed lower proportions of SSI for UKA (adjusted odds ratio, 0.47; 95% confidence interval, 0.37-0.60; P<0.001) and PJI (adjusted odds ratio, 0.47; 95% confidence interval, 0.34-0.65; P<0.001) than TKA. Other factors associated with both SSI and PJI included male sex, BMI >30kg/m , renal dysfunction and summer season. UKA was associated with lower proportions of SSI and PJI than TKA. Surgeons should carefully consider the indication of UKA before performing TKA, especially in patients with knee unicompartmental osteoarthritis who are at a high risk for SSI or PJI. UKA was associated with lower proportions of SSI and PJI than TKA. Surgeons should carefully consider the indication of UKA before performing TKA, especially in patients with knee unicompartmental osteoarthritis who are at a high risk for SSI or PJI.Clinical studies have demonstrated that allopregnanolone (3α5α-tetrahydroprogesterone, ALLO) has antidepressant-like effects on patients with depression. Previous studies have shown alteration of the astroglial glutamate transporter-1 (GLT-1) and glutamine synthetase (GS) in depression, and ALLO is known to modulate glutamate release. The present study aimed to investigate whether astroglial GLT-1 and GS are indeed involved in the antidepressant-like effects of ALLO in learned helplessness (LH) rats, a validated animal model of depression. The results of this study showed that bilateral microinjection of ALLO into the lateral ventricles could normalize the levels of GLT-1 and GS in the nucleus accumbens (NAc) and of GS in the hippocampal CA1 region of LH rats. These results suggest a certain connection between the antidepressant-like effects of ALLO and the astroglial GLT-1/GS system of the NAc in LH rats. Lacunar syndromes correlate with a lacunar stroke on imaging in 50% to 60% of cases. Computed tomography perfusion (CTP) is becoming the preferred imaging modality for acute stroke triage. We aimed to estimate the sensitivity, specificity, and predictive values for noncontrast computed tomography and CTP in lacunar syndromes, and for cortical, subcortical, and posterior fossa regions. A retrospective analysis of confirmed ischemic stroke patients who underwent acute CTP and follow-up magnetic resonance imaging between 2010 and 2018 was performed. Brain noncontrast computed tomography and CTP were assessed independently by 2 stroke neurologists. Receiver operating characteristic curve analysis was performed to estimate sensitivity, specificity, and area under the curve (AUC) for the detection of strokes in patients with lacunar syndromes using different CTP maps. We found 106 clinical lacunar syndromes, but on diffusion-weighted imaging, these consisted of 59 lacunar, 33 cortical, and 14 posterior fossa strokes.
