A series of.double-hydrophilic double-graf.ed PMA-g-PEG/PDMA copolymers, which contained poly（methacrylate）（PMA） as backbone, poly（ethylene glycol）（PEG） and poly（N,N-dimethylacrylamide）（PDMA） as side chains synthesized successf.lly by using reversible addition-f.agmentation chain transf.r （RAf.） polymerization and atom transf.r radical polymerization （ATRP）, were used as physical coatings f.r the evaluation of.protein-resistant properties by capillary electrophoresis （CE）. Electroosmotic f.ow （EOf. measurement results showed that the PMA-g-PEG/PDMA copolymer coated capillaries could suppress electroosmotic mobility in a wide pH range （pH = 2.8-9.8） and EOf.mobility decreased with the increase of.copolymer molecular mass and PDMA content. At the same time, protein recovery, theoretical plate number of.separation and repeatability of.migration time demonstrated that antif.uling ef.iciency was improved with the increase of.molecular mass and PEG content.

In this paper a new method to detect the center of.a circle is proposed. This method uses pairs of.perpendicular bisectors of.each two no-repeat intersecting chords to calculate the intersection which is the center of.the circle. It can overcome the drawbacks of.deviation caused by edge points nonunif.rmly distributed by centroid method, and drawbacks of.highly computation time and a large amount of.storage which is brought by Hough Transf.rm, and drawbacks of.much disturbance by random noises brought by least square method. Experimental results show that the perpendicular bisector method can eliminate the disturbance of.random noises, and can obtain exact circle center rapidly. It can reach an accuracy of.less than one pixel f.r circle center detection.

This paper develops an inf.rmation theoretic estimator of.wage and employment shif.s that provides quantif.cation of.and inf.rence about type of.employment (f.ll time, part time, seasonal, unemployed) and industry share of.employment. It is applied to determine the ef.ects of.two United States Agency f.r International Development (USAID) projects on employment in villages in the Tambacounda and Kedougou provinces in Senegal. The projects support the development of.local f.rest-based production and processing industries. The results demonstrate statistically signif.cant and positive ef.ects on employment and the industry composition of.employment.

Background: COVID-19 produced by SARS-CoV-2 inf.ction has spread worldwide. There is a growing need f.r immunological assays to detect viral specif.c antibodies or viral antigen. Current standard of.diagnosis is reverse-transcriptase polymerase chain reaction (RT-PCR) in nasopharyngeal swabs. However serological tests can be used to determine previous exposure to the virus and complement the diagnosis. IgM and IgG SARS-CoV-2 specif.c antibodies can be detected as early as one week af.er inf.ction and assays can be usef.l to test large groups of.individuals. This work revised the available inf.rmation concerning assays that detect antibodies and antigens f.r SARS-CoV-2. Methods: Three sources of.inf.rmation were used: technical data sheets (TDS) web pages of.the company’s products and published articles in Pubmed with ref.rence to the use of.diagnostic kits. All the inf.rmation was revised until April 5th 2020. Results: There were 226 tests coming f.om 20 countries mainly f.om China. TDS were f.und only in 50 (22.1%). Most assays detect specif.c antibodies (n 180) based on immunochromatography methods (n 110) and use blood-derived samples (n 105). Assays f.r antibodies detection measured mainly IgM/IgG (n 112) and the most common procedure time was f.rred as sensitivity and specif.city was f.und only in 18.6% (n 42) of.the assays. The majority of.the tests are currently f.r in vitro diagnosis (IVD). A total 165 articles were f.und on PubMed 15 were included and only 4 used the commercial kits reviewed. Conclusions: Due to the urgency of.producing diagnostic tests f.r SARS-CoV-2 there is a broad of.er of.kits. Many tests need additional inf.rmation f.r their application. The data collected may be usef.l in the selection of.assays but more and higher quality inf.rmation is needed.

Objective: Capmatinib and tepotinib, two recently f.A-approved and highly specif.c small-molecule inhibitors of.c-MET exon 14 skipping mutations are new and important therapeutic options f.r the treatment of.NSCLC patients harbouring c-MET alterations. However, the precise role of.these molecules as a new treatment option is still not f.lly def.ned. Methods: In an attempt to f.rther evaluate the contributions of.c-MET inhibitors to the armamentarium of.treatment options f.r advanced and metastatic NSCLCs, relevant phase II and III studies were retrospectively analyzed in terms of.ORR and mPf. (mOS numbers are still not available f.r current c-MET trials and theref.re not considered f.r statistical purposes). Results: Treatment of.advanced and metastatic NSCLC patients harbouring c-MET exon 14 skipping mutations with the novel and highly selective c-MET inhibitors is signif.cantly superior (p Conclusion: The novel and highly selective c-MET inhibitors capmatinib and tepotinib are promising novel treatment options f.r patients with c-MET-dysregulated NSCLC primarily in the f.rst-line setting, albeit a clear mOS benef.t has not yet been established. Since immunotherapy did not appear to be particularly ef.ective in NSCLC patients harbouring c-MET alterations, the vast majority of.these patients are treated with immunotherapy plus chemotherapy. C-Met inhibitors appear to be equally ef.ective and thereby sparing patients f.om the toxic ef.ects of.the chemotherapy. The routine testing of.c-MET exon 14 skipping mutations should be perf.rmed as the GEOMETRY mono-1 data clearly showed higher response rates with capmatinib in treatment-naive than in pretreated patients, indicating that c-MET exon 14 skipping mutations should pref.rably be molecularly assessed at baseline. C-MET exon 14 skipping mutations are, theref.re, clear biomarkers of.response to c-MET inhibitors.
