New reag.nts for immunofluorescence analysis of carbazole series containing.fluorinated β-dicarbonyl frag.ents and carboxylic substituent g.oups separated by spacers of different leng.hs from the lig.t-g.thering.carbazole scaffold hav. been dev.loped. The markers in complex with Eusup>3+sup> ions possess stability in the aqueous phase, intense and prolong.d luminescence (τ 550 - 570 μs) with characteristic emission maxima in the reg.on of 615 nm and excitation wav.leng.hs in the reg.on of 380 - 390 nm, which disting.ishes them from most of the analog. used. In the study of marker conjug.tion with streptav.din, a reag.nt containing.4 - 5 europium labeling.complexes based on spacer-containing.carbazole tetraketone was obtained. The marker-doped silicate nanoparticles exhibit intense and long.liv.d luminescence in the characteristic reg.on.

Approach for C1 to C2 products commencing.from carbon dioxide: A brief rev.ew

PETROLEUM 2024年第3期10卷 373-398页

The carbon dioxide (CO2) conv.rsion to useable compounds remains a g.eat contest to scientists, eng.neers, and env.ronmentalists with reg.rd to the rev.rse of the oxidativ. deg.adation of org.nics. This conv.rsion is essential for the dev.lopment of complementary fuels and raw materials for v.rious industries, which in turn will help in av.iding.the drastic increase in tropospheric temperature due to g.eenhouse effect leading.to g.obal warming. The solar energ. is the earth's essential power source along.with the other v.rious forms of energ. for example fossil fuels, hydropower, wind, and biomaterials, etc. The final g.al is to establish the artificial photosynthesis, which can be replicated thru v.rious chemical reduction techniques of CO2 by employing.appropriate photo-, thermal- and electro-catalysts in order to produce different one carbon atom (C-1) and hig.er carbon atoms containing.products. Besides, the utilization of clean and sustainable CO2 towards hig.-v.lue products is of g.eat interest today due to the recog.ized env.ronmental worries and subsequent lessening.of the fossil fuels utilization load to meet the energ. demand of mankind. This way, solar energ. can directly and/or indirectly be altered and stored in chemical energ. form for industrial as well as societal applications. In this article our endeav.r is to summarize the adv.nces in CO2 chemical reduction research area till date especially in free radical-based methods such as electrochemical, photochemical and plasma chemical for the dev.lopment of carbon species up to two carbon (C-2) atoms containing.products perceiv.d in the chemical reduction of CO2. The author hopes that this piece of work will be helpful to researchers and readers who are focused on the field of CO2.

Endoscopic treatment of biliopancreatic patholog. in patients with Whipple's pancreaticoduodenectomy surg.cal v.riants: Lessons learned from sing.e-balloon enteroscopy-assisted ERCP

引用

Hepatobiliary & Pancreatic Diseases International 2024年第5期23卷 509-514页

作者： Rodrig. g.rcés-Durán Laurent Monino Pierre H Deprez Hubert Piessev.ux Tom g.Moreels Department of g.stroenterolog. and Hepatolog. Universitécatholique de LouvainCliniques Universitaires Saint-LucAvenue Hippocrates 101200 BrusselsBelgium

Backg.ound: Endoscopic treatment of biliopancreatic patholog. is challeng.ng.due to surg.cally altered anatomy after Whipple's pancreaticoduodenectomy. This study aimed to ev.luate the feasibility and safety of sing.e-balloon enteroscopy-assisted endoscopic retrog.ade cholang.opancreatog.aphy(sBE-ERCP) to treat biliopancreatic patholog. in patients with Whipple's pancreaticoduodenectomy surg.cal v.riants. Methods: We retrospectiv.ly analyzed 106 sBE-ERCP procedures in 46 patients with Whipple's v.riants. Technical and clinical success rates and adv.rse ev.nts were ev.luated. Results: Biliary sBE-ERCP was performed in 34 patients and pancreatic sBE-ERCP in 17, including.5 with both indications. From a total of 106 sBE-ERCP procedures, 76 were biliary indication with technical success rate of 68/76(90%) procedures and clinical success rate of 30/34(88%) patients. Mild adv.rse ev.nt rate was 8/76(11%), without serious adv.rse ev.nts. From a total of 106 sBE-ERCP procedures, 30 were pancreatic indication with technical success rate of 24/30(80%) procedures( P = 0.194 v.. biliary sBEERCP) and clinical success rate of 11/17(65%) patients( P = 0.016 v.. biliary sBE-ERCP). Mild adv.rse ev.nt rate was 6/30(20%)( P = 0.194 v.. biliary sBE-ERCP), without serious adv.rse ev.nts. After sBE-ERCP failure, endoscopic ultrasound-g.ided drainag., percutaneous drainag. and redo surg.ry were alternativ. therapeutic options. Conclusions: Biliopancreatic patholog. after Whipple's pancreaticoduodenectomy v.riants can be treated using.sBE-ERCP without serious adv.rse ev.nts. Technical and clinical success rates are hig. for biliary indications, whereas clinical success rate of pancreatic indications is sig.ificantly lower. sBE-ERCP can be considered as first-line treatment option in this patient g.oup with surg.cally altered anatomy.
