Hydroxychloroquine in the treatment of adult patients with Covid-19 infection in a primary care setting (LIBERTY): A structured summary of a study protocol for a randomised controlled trial

Trials, 2021
Objectives The primary objective of this study is to evaluate the therapeutic potential of hydroxychloroquine (HCQ) in the treatment of adult patients with PCR-confirmed Covid-19 infection in a primary open-care setting, as compared to placebo. The study

The Antimicrobial Resistance Characteristics of Imipenem-Non-Susceptible, Imipenemase-6-Producing Escherichia coli

Antibiotics, 2021
Imipenemase-6 (IMP-6) type carbapenemase-producing Enterobacteriaceae is regarded as dangerous due to its unique lack of antimicrobial susceptibility. It is resistant to meropenem (MEPM) but susceptible to imipenem (IPM).

Increased Virulence of Outer Membrane Porin Mutants of Mycobacterium abscessus

Frontiers in Microbiology, 2021
Chronic pulmonary infections caused by non-tuberculous mycobacteria of the Mycobacterium abscessus complex (MABSC) are emerging as a global health problem and pose a threat to susceptible individuals with structural lung disease such as cystic fibrosis ...

Evolution of Mycobacterium abscessus in the human lung: Cumulative mutations and genomic rearrangement of porin genes in patient isolates

Virulence, 2023
Background Mycobacterium abscessus subspecies massiliense (M. massiliense) is increasingly recognized as an emerging bacterial pathogen, particularly in cystic fibrosis (CF) patients and CF centres’ respiratory outbreaks.

Emergence of the Dickeya genus involved duplication of the OmpF porin and the adaptation of the EnvZ-OmpR signaling network

Microbiology Spectrum, 2023
Genome evolution, and more specifically gene duplication, is a key process shaping host–microorganism interaction. The conserved paralogs usually provide an advantage to the bacterium to thrive. If not, these genes become pseudogenes and disappear. Here,

Porin from Rhodopseudomonas sphaeroides [PDF]

Journal of Bacteriology, 1984
A protein homooligomer was purified from both the cell envelope fractions and the saline extracts of Rhodopseudomonas sphaeroides cells. This oligomer exhibited strong porin activity when reconstituted into proteoliposomes with egg phosphatidylcholine. In the saline extracts of both chemotrophically and phototrophically grown cells, the porin oligomer ...

Opettajan asiantuntijuus muutoksessa – asiantuntijuus ja sen jakamisen diskurssit digitaalisessa oppimisympäristössä

Kasvatus & Aika, 2019
Asiantuntijuus ja asiantuntijatyö on perinteisesti liitetty spesifeihin ammattialoihin ja professionaalisuuteen. Teknologian lisääntyvä käyttö asiantuntijatyössä kuitenkin muuttaa asiantuntijuuden ilmenemistä ja sen rajoja. Tässä artikkelissa tarkastelen
