O objetivo deste trabalho foi realizar uma estimativa da carga de morbimortalidade Covid-19 no Maranhão período 24 meses, entre os anos 2020 e 2022. Para isso, dados utilizados procedem dos boletins Secretaria Estado Saúde do Maranhão, portal IBGE, Global Burden of Disease Study 2019. Com tais informações (casos confirmados óbitos, vida pesos incapacidade), foram estimados a letalidade média DA...

Nanometer-thick and crystalline sp3-bonded carbon sheets are promising new wide band-gap semiconducting materials for electronics, photonics, medical devices. Diamane was prepared from the exposure of bi-layer graphene to hydrogen radicals produced by hot-filament process at low pressure temperature. A sharp stretching mode observed in ultraviolet Raman spectra around 1344–1367 cm?1 while no sp...

The immunomodulatory and antimicrobial effects of methanol extract air-dried, powdered leaves Uvaria chamae (MEUL) was evaluated in this study using standard methods. Graded doses (50 mg/kg body weight, 100 200 weight 400 weight) the were administered to winster rats. control group given dimethyl sulphoxide (DMSO). Immunomodulatory effect assessed by delayed type hypersensitivity (DTH) haemaggl...

Rhamnolipid (RL) can inhibit biofilm formation of Escherichia coli O157:H7, but the associated mechanism remains unknown. We here conducted comparative physiological and transcriptomic analyses cultures treated with RL untreated to elucidate a potential by which may in E. O157:H7. Anti-biofilm assays showed that over 70% O157:H7 capacity was inhibited treatment 0.25–1 mg/mL RL. Cellular-level a...

Using a 3D multispecies magnetohydrodynamic model, we investigated the effect of solar wind dynamic pressure ( P d ) with different densities and velocities on subsolar standoff distance r 0 Martian magnetic pileup boundary (MPB). We fixed maximum condition, strongest crustal field located in dayside region, Parker spiral interplanetary at Mars. simulated 35 cases range 0.1494 to 7.323 nPa (sol...
