Original ruthenium supported ionic liquid phase (SILP) catalysts based on alginates as supports were developed for olefin metathesis reactions. The marine biopolymer, which fulfills most of the requisite properties for a support such as widespread abundance, insolubility in the majority of organic solvents, a high affinity for ionic liquids, high chemical stability, biodegradability, low cost, and easy processing, was impregnated by [bmim][PF6 ] containing an ionically tagged ruthenium catalyst. These biosourced catalysts show promising performances in ring-closing metathesis (RCM) and cross-metathesis (CM) reactions, with a high level of recyclability and reusability combined with a good reactivity.
A 25-year-old male with end-stage cystic fibrosis (CF) with genotype F508del/F508del presented to the clinic complaining of bilateral knee and ankle pain. He had severe lung disease (forced expiratory volume 1 {FEV1} 19% of predicted), chronic colonization with achromobacter, malnutrition, and CF-related diabetes. On physical examination, he was found to have bilateral knee swelling as well as pain on flexion and extension of the wrists and ankles without erythema or warmth. He was empirically started on prednisone and tramadol; however, at a three-month follow-up visit, he remained symptomatic. He was sent for a wholebody bone scan, which was consistent with hypertrophic pulmonary osteoarthropathy (HPOA). He was started on highly effective modulator therapy with elexacaftor/tezacaftor/ivacaftor and symptoms spontaneously resolved without further intervention.
downstage were calculated with 95% confidence intervals. A 5% significance level was adopted.RESULTS: A total of 51 consecutive patients with locally advanced uterine cervical cancer were included. A poor agreement was found between FIGO and PET/CT staging (Kappa50.06). There were 40 cases of disagreement between clinical and FDG PET/CT staging. Thirty-eight of them were upstaged (95%) and two downstaged (5%). Of those upstaged, 15 (39.4%) were classified as stage IVB-distant metastasis.CONCLUSION: This study shows that the use of FDG PET/CT improves staging patients with locally advanced cervical carcinoma by identifying distant abnormal lymph nodes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
