Sofosbuvir, ribavirin and pegylated interferon for a daclatasvir-resistent genotype 3 hepatitis C virus: case report and review.

Chronic Hepatitis C relapse after liver transplantation can lead to graft failure within a short time period. The high efficacy and good safety profile of direct-acting antivirals has led to consensual recommendations for using interferon-free treatment after liver transplantation. However, pegylated interferon may still be required for genotype 3 non-responders. We treated a liver graft recipient...

Efficient design and analysis of randomized controlled trials in rare neurological diseases: An example in Guillain-Barré syndrome.

Randomized controlled trials (RCTs) pose specific challenges in rare and heterogeneous neurological diseases due to the small numbers of patients and heterogeneity in disease course. Two analytical approaches have been proposed to optimally handle these issues in RCTs: covariate adjustment and ordinal analysis. We investigated the potential gain in efficiency of these approaches in rare and hetero...

Characterization of Galectin-2 from Nile tilapia (Oreochromis niloticus) involved in the immune response to bacterial infection.

galectin-2 plays important roles in innate and adaptive immunity. In this study, galectin-2 (OnGal-2) was identified from Nile tilapia (Oreochromis niloticus). Its tissue distribution and expression patterns following bacterial infection were also investigated. OnGal-2 is widely distributed in various tissues of healthy tilapia. After Streptococcus agalactiae challenge, OnGal-2 expressions were si...

Hydrogen peroxide-inactivated bacteria induces potent humoral and cellular immune responses and releases nucleic acids.

The problem of nosocomial infection is seriously escalating. Bacterial vaccines are indispensable for preventing infections caused by multi-drug resistant organisms. Some researchers have put forward the use of hydrogen peroxide (HO) as a new technology platform for virus deactivation. This deactivated virus can induce the number of CD8 T lymphocytes, which can enhance antiviral responses. Althoug...

Hepatoprotective effects of rosmarinic acid: Insight into its mechanisms of action.

Liver diseases such as hepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma are one of the major health challenges in the world and many conditions such as inadequate nutrition, viral infection, ethanol and drug abuse, xenobiotic exposure, and metabolic diseases have been implicated in the development and progression of liver diseases. Several factors including lipid peroxidation, producti...

Efficiency of the flagellar propulsion of Escherichia coli in confined microfluidic geometries.

Bacterial movement in confined spaces is routinely encountered either in a natural environment or in artificial structures. Consequently, the ability to understand and predict the behavior of motile bacterial cells in confined geometries is essential to many applications, spanning from the more classical, such as the management complex microbial networks involved in diseases, biomanufacturing, min...
