Phage therapy, viral phage therapy, or phagotherapy is the therapeutic use of bacteriophages for the treatment of pathogenic bacterial infections. [1] [2] [3] This therapeutic approach emerged at the beginning of the 20th century but was progressively replaced by the use of antibiotics in most parts of the world after the Second World War.
Double-stranded DNA phage lysins tend to lie within the 25 to 40 kDa range in terms of size. A notable exception is the streptococcal PlyC endolysin, which is 114 kDa. PlyC is not only the biggest and most potent lysin, but also structurally unique since it is composed of two different gene products, PlyCA and PlyCB, with a ratio of eight PlyCB subunits for each PlyCA in its active conformation.
In the European Union, the combination is indicated for the treatment of COVID‑19 in people aged twelve years of age and older weighing at least 40 kilograms (88 lb) who do not require supplemental oxygen and who are at high increased risk of progressing to severe COVID‑19; [10] and for the prevention of COVID‑19 in people aged twelve years of age and older weighing at least 40 kilograms ...
Endolysins are specialized enzymes derived from bacteriophages, viruses that infect bacterial cells in order to replicate within them. Because phages have coevolved with their bacterial hosts, the endolysin system is very efficient at degrading bacterial cell walls. [3]
This registry based, multi-center, multi-country data provide provisional support for the use of ECMO for COVID-19 associated acute hypoxemic respiratory failure. Given that this is a complex technology that can be resource intense, guidelines exist for the use of ECMO during the COVID-19 pandemic. [85] [86] [87]
The antiretroviral regimen used in PEP is the same as the standard highly active antiretroviral therapy used to treat AIDS. A typical prescription is a 28-day course of emtricitabine/tenofovir pills containing 200 mg of emtricitabine and 245 mg of tenofovir disoproxil to be taken once daily, and 400 mg pills of raltegravir to be taken twice ...
There is little research on microneedling as a monotherapy (single treatment) for hair loss since most studies combined it with other therapies like topical minoxidil or platelet-rich plasma (PRP ...
