di Filippo, Luigi;Castellino, Laura;Giustina, Andrea research published 《 Occurrence and response to treatment of Graves’ disease after COVID vaccination in two male patients》, the research content is summarized as follows. COVID-19 had dramatic impact worldwide and various vaccines anti-SARS-CoV-2 were rapidly developed. Despite a good safety profile in clin. trials, rare and severe side effects of vaccines have been reported, including thyroid dysfunctions. In particular, occurrence of Graves’ disease (GD) post-vaccination with Tozinameran (Pfizer-BioNTech) was reported in three female subjects and only one male prevalently in young-adult age somewhat reflecting the epidemiol. age and sex distribution of the disease. Reported here is the occurrence and the response to treatment of GD in two male patients after Vaxzevria (Oxford-AstraZeneca) SARS-CoV-2 vaccinations. Case 1 is of a previously healthy, past-smoker, 32-yr-old male patient, without any personal or family history of endocrine and autoimmune diseases, ten days after the second dose of Vaxzevria vaccine developed anxiety, tachycardia and palpitations, without signs of orbitopathy or local pain. Tyroid-function tests revealed decreased TSH with elevated free-T4 and free-T3 levels and elevated thy rotropin recept or-antibodies (TRAbs). After three months of therapy his thyroid function is currently normal and TRAbs levels halved on 100 mg/daily dose of propylthiouracil. Case 2 is of a reviously healthy, past-smoker, 35-yr-old male patient, without any personal or family history of endocrine and autoimmune disease, 5 days after the first dose of Vaxzevria vaccine developed headache, nausea, asthenia, palpitations, tachycardia, mild eyes-redness and superior palpebral retraction. Thyroid-function tests revealed sup- pressed TSH with elevated free-T4 and free-T3 levels and elevated TRAbs. After three months of therapy his thyroid function and TRAbs levels are currently normal on 5 mg/daily dose of thiamazole. It cannot be excluded also a possible influence of vitamin D status on GD occurrence after COVID-19 vaccination, although data on VD status in our patients were not available. In conclusion, although COVID-19 vaccination is currently not contraindicated in patients with stable autoimmune endocrine diseases,this data suggest a note of caution in administering a further vaccine dose to patients that developed GD in the first weeks after vaccination. Moreover, it is suggested to carefully consider if submitting patients with recent onset or non-stable GD to all types of COVID-19 vaccination.

Deyko, Grigory S.;Glukhov, Lev M.;Kustov, Leonid M. research published 《 Hydrogen storage in organosilicon ionic liquids》, the research content is summarized as follows. New structures of ionic liquids have been studied as liquid organic hydrogen carriers. The hydrogenation of organosilicon compounds containing a carbazole fragment was carried out for the first time. The N-(CH₂)₃-Si fragment in the composition of the hydrogen carrier based on organosilicon moieties was found to be more suitable than the N-CH₂-Si bond. Ionic liquids with a carbazole fragment containing silicon atoms were synthesized for the first time. It was possible to significantly reduce the m.p. of such ionic liquids by introducing an organosilicon linker between carbazole nitrogen and imidazolium ion. The synthesized ionic liquid is a liquid at room temperature Hydrogenation-dehydrogenation experiments demonstrated that such ionic liquids are thermally stable up to at least 220°C, and nearly quant. conversion can be achieved. Both the hydrogenation and dehydrogenation processes were carried out using the same Pd/C catalyst. The theor. total gravimetric hydrogen capacities for synthesized ionic liquids are 2.05% and 1.58%.

Deshayes, Samuel;Dolladille, Charles;Dumont, Anael;Martin Silva, Nicolas;Chretien, Basile;De Boysson, Hubert;Alexandre, Joachim;Aouba, Achille research published 《 A Worldwide Pharmacoepidemiologic Update on Drug-Induced Antineutrophil Cytoplasmic Antibody-Associated Vasculitis in the Era of Targeted Therapies》, the research content is summarized as follows. The literature supporting the role of a specific drug in the onset of drug-induced antineutrophil cytoplasmic antibody-associated vasculitis (AAV) mainly relies on case reports or short series and implicates old treatments. The advent of new treatments may have modified the epidemiol. of these adverse drug reactions. This study was undertaken to update the list of drugs associated with AAV by using a pharmacovigilance-based data mining approach. We collected data on adverse drug reactions reported using the Medical Dictionary for Regulatory Activities preferred term anti-neutrophil cytoplasmic antibody pos. vasculitis up to Nov. 2020 from the World Health Organization pharmacovigilance database (VigiBase). For each retrieved drug, a case-noncase anal. was performed, and disproportionate reporting was calculated by using the information component (IC). A pos. IC025 value, which is the lower end of the 95% credibility interval, was considered significant. A total of 483 deduplicated individual case safety reports of drug-induced AAV involving 15 drugs with an IC025 >0 were retrieved. Of the individuals with drug-induced AAV for whom data on sex were available (n = 371), 264 (71.2%) were women. The median age at onset of drug-induced AAV was 62 years (quartile 1 [Q1]-Q3 45-72 years), and the median time from the introduction of the suspected drug to the onset of drug-induced AAV was 9 mo (Q1-Q3 1-36 mo). Drug-induced AAV was considered serious in 472 (98.1%), and was fatal in 43 (8.9%), of 481 cases. The drugs associated with the highest disproportionate reporting were hydralazine, propylthiouracil, thiamazole, sofosbuvir, minocycline, carbimazole, mirabegron, and nintedanib. Our findings strengthen the evidence of an association of AAV with previously suspected drugs, but also identify 3 new drugs that may cause drug-induced AAV. Particular attention should be given to these drugs by prescribers and in exptl. studies.

Heterodinuclear complexes with a direct metal-metal bond offer the possibility of unique mechanisms and intermediates. The Cp(CO)₂Fe-Cu(IPr) (IPr = N,N-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) heterodinuclear complex 1 is reported to photochem. catalyze arene borylation. To examine possible initial steps of photoinitiated catalysis, the authors synthesized a triethylsilyl-substituted Fe-Cu catalyst derivative 5 that provided cyclohexane solubility to conduct time-resolved UV-IR studies. Time-resolved vibrational spectroscopic measurements suggest that photolysis of 5 stimulates CO dissociation without Fe-Cu metal-metal bond cleavage. UV-IR measurements of 5 with added pinacolborane (HBPin) showed a very similar set of IR bleaches and a new monocarbonyl IR absorbance, and HBPin appears to stabilize the monocarbonyl species. Probably arene borylation catalysis begins with a photochem. step rather than a relatively endothermic thermal-induced cleavage of the Fe-Cu bond, and therefore a new possible catalytic cycle is proposed.

CO₂ fixation is a prominent research theme that attracts the attention of scientists, stakeholders and governmental entities with the aim of ultimately bringing com. products to the market. Herein, a series of mono-, bi-functional and polymeric imidazolium-based catalysts were synthesized and utilized for the production of cyclic carbonates (CCs) using epoxides and 1 bar of CO₂ under mild reaction conditions. In addition, three onium salts, namely, ammonium, phosphonium, and pyridinium, were synthesized and characterized using ¹H/¹³C NMR (NMR) and attenuated total reflectance-Fourier transform IR (ATR-FTIR) spectroscopies, together with thermal gravimetric anal. (TGA), high-resolution mass spectrometry (HRMS) and elemental anal. (EA). All the investigated organocatalysts showed almost quant. CC conversions, which were isolated from the crude reaction and identified spectroscopically. D. functional theory (DFT) calculations revealed that the aforementioned onium salts followed the same detailed mechanism for the cycloaddition reaction, which started with the electrostatic interaction of the onium centers with the oxygen atom of the epoxide. Even in the case of the imidazolium nucleus, the acidic C₂ proton played a marginal role in the epoxide activation than in the ring-opening step.
