CaZnO-based nanoghosts for the detection of ssDNA, pCRISPR and recombinant SARS-CoV-2 spike antigen and targeted delivery of doxorubicin
PublikacjaOverexpression of proteins/antigens and other gene-related sequences in the bodies could lead to significant mutations and refractory diseases. Detection and identification of assorted trace concentrations of such proteins/antigens and/or gene-related sequences remain challenging, affecting different pathogens and making viruses stronger. Correspondingly, coronavirus (SARS-CoV-2) mutations/alterations and spread could lead to overexpression...

Development of potent and effective SARS-CoV-2 main protease inhibitors based on maleimide analogs for the potential treatment of COVID-19
PublikacjaIn the present work, we report a new series of potent SARS-CoV-2 Main Protease (Mpro) inhibitors based on maleimide derivatives. The inhibitory activities were tested in an enzymatic assay using recombinant Mpro (3CL Protease from coronavirus SARS-CoV-2). Within the set of new Mpro inhibitors, 6e demonstrated the highest activity in the enzymatic assay with an IC50 value of 8.52 ± 0.44 mM. The IC50 value for Nirmatrelvir (PF-07321332,...

Ocena i predykcja dynamiki epidemii COVID-19 na podstawie obecności wirusa SARS-CoV-2 w ściekach
PublikacjaCOVID-19 - wywołany przez wirusa SARS-CoV-2, prowadzący m.in. do ostrej niewydolności oddechowej, spowodował kryzys w służbie zdrowia i istotne implikacje społeczno-gospodarcze. Główną drogą przenoszenia SARS-CoV-2 jest droga kropelkowa, czyli aerozole z dróg oddechowych, generowane przez kaszel, kichanie i mówienie. Zakażenie SARS-CoV-2 może nie tylko wpływać na układ oddechowy, powodując gorączkę, kaszel, wyciek z nosa, duszność...

Direction of Arrival Estimation Based on Received Signal Strength Using Two-Row Electronically Steerable Parasitic Array Radiator Antenna
PublikacjaIn this paper, we present a novel approach to direction-of-arrival (DoA) estimation using two-row electronically steerable parasitic array radiator (ESPAR) antenna which has 12 passive elements and allows for elevation and azimuth beam switching using a simple microcontroller, relying solely on received signal strength (RSS) values measured at the antenna output port. To this end, we thoroughly investigate all 18 available 3D antenna...

Bioactive hybrid metal-organic framework (MOF)-based nanosensors for optical detection of recombinant SARS-CoV-2 spike antigen
PublikacjaFast, efficient, and accurate detection of SARS-CoV-2 spike antigen is pivotal to control the spread and reduce themortality of COVID-19. Nevertheless, the sensitivity of available nanobiosensors to detect recombinant SARS-CoV-2 spike antigen seems insufficient. As a proof-of-concept, MOF-5/CoNi2S4 is developed as a low-cost, safe, and bioactive hybrid nanostructure via the one-pot high-gravity protocol. Then, the porphyrin, H2TMP,...

Comparison of s-factor according to SOLAS and SEM for ro-pax vessels
PublikacjaPokazano różnice pomiędzy mnożnikami s dla promów pasażerskich, obliczonych wg konwencji SOLAS oraz metody statycznej równoważności (SEM). Obliczenia wykonane dla promu ''Polonia'' i statku prostopadłościennego wskazują na cztery wnioski. 1) W wypadku małej stateczności, mnożniki s wg SOLAS są zdecydowanie mniejsze od s wg SEM, 2) im mniejsza stateczność, tym większe różnice między nimi, 3) konwencja SOLAS niedoszacowuje rzeczywiste...
