Multiple sclerosis and SARS-CoV-2 infection

Universitatea de Medicină și Farmacie „Grigore T. Popa” Iași, România, Clinica I Oftalmologie, Spitalul Clinic Județean de Urgență „Sf. Spiridon”, Iași, RomâniaSummary. We analyzed the case of a patient with multiple sclerosis associated with SARS-CoV-2 infection. The clinical appearance of the ophthalmologist does not justify the decrease in AV, which is why it is recommended to perform an MRI in an emergency. The patient accuses the decrease in visual acuity in the left eye. The appearance described is suggestive for multiple sclerosis. PCR testing was positive. After 14 days PCR test was negative but the ophthalmological evolution was unfavorable. Intravenous emergency treatment with Solumedrol was initiated for 5 days. The particularity of the case is due to the fulminant onset of multiple sclerosis in the context of SARS-CoV-2 infection and the unfavorable evolution in terms of AV, despite early treatment.Introducere. Pacientă, în vârstă de 16 ani, se prezintă în Clinica I Oftalmologie a Spitalului „Sf. Spiridon”, Iași, acuzând scăderea acuității vizuale la ochiul stâng cu debut acut. Pacienta nu prezintă alte antecedente personale patologice. AVOD=1 fc, AVOS= pmm., PIOAO=12mmHg. La examinarea polului anterior, nu se constată elemente patologice. La examinarea polului posterior, discul optic este normal colorat, are contur net, C/D=0,1, artere și vene cu calibru normal, maculă fără leziuni. Aspectul clinic oftalmologic nu justifică scăderea AV, motiv pentru care se recomandă efectuarea unui RMN în urgență. Se identifică leziuni în hipersemnal T2 și FLAIR cu restricție de difuzie localizată periventricular pe partea dreaptă, în contrast cu cornul posterior al ventriculului lateral drept cu diametru de 17/15 mm și două în centri senzoriali, una mai mare de 9,6mm parietal drept în substanța albă, periventricular, talamic drept, 9,6 mm în medulla oblongata de 13 mm. Aspectul descris este sugestiv pentru scleroză multiplă. Testarea PCR pentru SARS-CoV-2 a avut rezultat pozitiv, pacienta fiind asimptomatică. S-a format o echipă multidisciplinară alcătuită din oftalmologi, neurologi și medici infecționiști și s-a inițiat tratamentul în urgență intravenos cu Solumedrol timp de 5 zile, continuat cu Medrol per os. Evoluție. După 14 zile, testul PCR pentru SARSCoV- 2 s-a negativat, însă evoluția oftalmologică a fost nefavorabilă. Pacienta se prezintă după 3 luni, în urgență, acuzând percepția unui scotom central la OD. AVOD=0,6, iar AVOS a rămas pmm. La RMN leziunile au aspect staționar. După tratamentul intravenos cu Solumedrol 3 zile și per os cu Medrol, scotomul central de la OD se reduce în dimensiuni și AVOD se îmbunătățește la 0,8 fcnc. Discuții: Rămâne în discuție deschisă dacă infecția cu SARS-CoV-2 la persoane nevaccinate poate precipita debutul fulminant al unor patologii în stare latentă. Concluzii. Particularitatea cazului se datorează debutului fulminant al sclerozei multiple în contextul infecției cu SARS-CoV-2 și evoluției nefavorabile din punct de vedere al AV, în ciuda tratamentului instaurat precoce

Synthesis and Degradation of Schiff Bases Containing Heterocyclic Pharmacophore

This paper reports on the synthesis and characterization of two Schiff bases bearing 1,2,4-triazolic moieties, namely 4H-4-(2-hydroxy-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole and 4H-4-(4-nitro-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole using thin layer chromatography, melting interval, elemental analysis, spectroscopy and thermal stability studies

Preparation and Antibacterial Properties of Substituted 1,2,4-Triazoles

Background. Both 1,2,3- and 1,2,4-triazoles are nowadays incorporated in numerous antibacterial pharmaceutical formulations. Aim. Our study aimed to prepare three substituted 1,2,4-triazoles and to evaluate their antibacterial properties. Materials and Methods. One disubstituted and two trisubstituted 1,2,4-triazoles were prepared and characterised by physical and spectroscopic properties (melting point, FTIR, NMR, and GC-MS). The antibacterial properties were studied against three bacterial strains: Staphylococcus aureus (ATCC 25923), Escherichia coli (ATCC 25922), and Pseudomonas aeruginosa (ATCC 27853), by the agar disk diffusion method and the dilution method with MIC (minimal inhibitory concentration) determination. Results. The spectroscopic characterization of compounds and the working protocol for the synthesis of the triazolic derivatives are described. The compounds were obtained with 15–43% yields and with high purities, confirmed by the NMR analysis. The evaluation of biological activities showed that the compounds act as antibacterial agents against Staphylococcus aureus (ATCC 25923), while being inactive against Escherichia coli (ATCC 25922) and Pseudomonas aeruginosa (ATCC 27853). Conclusions. Our results indicate that compounds containing 1,2,4-triazolic moiety have great potential in developing a wide variety of new antibacterial formulations

Measurement of the relative width difference of the B0B^0-Bˉ0\bar B^0 system with the ATLAS detector

20 pages plus author list + cover page (38 pages total), 5 figures, 2 tables, submitted to Journal of High Energy Physics, All figures including auxiliary figures are available at http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/BPHY-2015-01/ - See paper for full list of authorsInternational audienceThis paper presents the measurement of the relative width difference $\Delta \Gamma_d / \Gamma_d$ of the $B^0$-$\bar B^0$ system using the data collected by the ATLAS experiment at the LHC in $p p$ collisions at $\sqrt{s} = 7$ TeV and $\sqrt{s} = 8$ TeV and corresponding to an integrated luminosity of 25.2 fb$^{-1}$. The value of $\Delta \Gamma_d / \Gamma_d$ is obtained by comparing the decay-time distributions of $B^0 \to J/\psi K_S$ and $B^0 \to J/\psi K^{*0}(892)$ decays. The result is \Delta \Gamma_d / \Gamma_d = (-0.1 \pm 1.1~\mbox{(stat.)} \pm 0.9~\mbox{(syst.)}) \times 10^{-2}. Currently, this is the most precise single measurement of $\Delta \Gamma_d / \Gamma_d$. It agrees with the Standard Model prediction and the measurements by other experiments
