UnknownKey mutations in the C-terminus of the HBV surface glycoprotein correlate with lower HBsAg levels in vivo, hinder HBsAg secretion in vitro and reduce HBsAg structural stability in the setting of HBeAg-negative chronic HBV genotype-D infection.
Increasing evidences suggest that HBsAg-production varies across HBV-genotypes. HBsAg C-terminus plays a crucial role for HBsAg-secretion. Here, we evaluate HBsAg-levels in different HBV-genotypes in HBeAg-negative chronic infection, the correlation of specific mutations in HBsAg C-terminus with HBs...

UnknownGMMA decorated with mucin 1 Tn/STn mimetics elicit specific antibodies response and inhibit tumor growth.
Carbohydrate-based therapeutic vaccines are actively pursued as targeted immunotherapy to treat cancer. Aberrant glycosylation is indeed of paramount importance in tumors, leading to the formation of "neo-epitopes", known as tumor-associated carbohydrate antigens (TACAs), crucial in cancer onset, de...

UnknownTocilizumab for patients with COVID-19 pneumonia. The single-arm TOCIVID-19 prospective trial.

Background

Tocilizumab blocks pro-inflammatory activity of interleukin-6 (IL-6), involved in pathogenesis of pneumonia the most frequent cause of death in COVID-19 patients.

Methods

A multicenter, single-arm, hypothesis-driven trial was planned, according to a phase 2 design, to study...

UnknownCenter-Related Determinants of VKA Anticoagulation Quality: A Prospective, Multicenter Evaluation.

Background

Center-specific TTR (c-TTR) is a measure reporting the mean patient TTR within an anticoagulation clinic describing the quality of anticoagulant monitoring offered by that clinic. c-TTR has a considerable between-center variation, but its determinants are poorly understood.
