We performed a study to (i) investigate efficacy of an Escherichia coli/Salmonella spp./Listeria monocytogenes-targeting bacteriophage cocktail (tentatively named F.O.P.) reduce human pathogenic E. coli strain O157:H7 in experimentally infected mice, and (ii) determine how bacteriophages impact the normal gut microbiota when compared with antibiotic therapy. A total 85 mice were inoculated Ec231 [nalidixic acid resistant (NalAcR)] via oral gavage, randomized into six groups separated three...

Polyphenol-rich cranberry extracts decrease intestinal inflammation, alter gut microbiota, and permeability in obese mice, but the effect has not been investigated adults who are obese. The purpose of this randomized double-blind, cross-over feeding study (BMI = 37.4 ± 1.2 kg/m2) otherwise healthy (n 36) 35.4 1.3 years was to determine effects consuming 480 mL a high polyphenolic or control beverage daily for 2 weeks on gastrointestinal permeability, markers inflammation immune function,...

Acute lung injury in COVID-19 results diffuse alveolar damage with disruption of the alveolar-capillary barrier, coagulation activation, fibrin deposition and pulmonary capillary thrombi. Nebulized recombinant tissue plasminogen activator (rt-PA) has potential to facilitate localized thrombolysis compartment improve oxygenation. In this proof-of-concept safety study, adults COVID-19-induced respiratory failure a <300 mmHg PaO

Nebulized thrombolysis offers locally targeted therapy with potentially lower bleeding risk than systemic administration for coronavirus disease 2019 (COVID-19) respiratory failure. In a proof-of-concept safety study, adult patients COVID-19-induced failure and &amp;lt;300mmHg PaO2/FiO2 (P/F) ratio, requiring invasive mechanical ventilation (IMV) or non-invasive support (NIRS) received nebulized rt-PA in two cohorts (C1 C2), alongside standard of care during the first UK COVID-19 waves....
