A re-entrant phase transition in the survival of secondary infections on networks [PDF]

, 2018
We study the dynamics of secondary infections on networks, in which only the individuals currently carrying a certain primary infection are susceptible to the secondary infection. In the limit of large sparse networks, the model is mapped to a branching process spreading in a random time-sensitive environment, determined by the dynamics of the ...

A Versatile High‐Throughput Single‐Cell Screening Platform for Profiling Antigen‐Specific Long‐Lived B Cells in Blood and Bone Marrow

Advanced Science, EarlyView.
The MoSMAR‐chip platform provides a high‐throughput and cost‐effective tool for identifying and characterizing antigen‐specific antibody‐secreting cells (ASCs) and memory B cells (MBCs) at the single‐cell level. The ASCs from coronavirus disease 2019 (COVID‐19) vaccine‐immunized mice were successfully analyzed, revealing diverse neutralizing antibodies

Fermented lingonberry juice's effects on active MMP‐8 (aMMP‐8), bleeding on probing (BOP), and visible plaque index (VPI) in dental implants—A clinical pilot mouthwash study

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1322-1330, December 2022., 2022
Abstract Objectives We aimed to study the effects of fermented lingonberry juice (FLJ) as a mouthwash on the levels of active matrix metalloproteinase‐8 (aMMP‐8) in peri‐implant sulcular fluid (PISF), bleeding on probing (BOP), and visible plaque index (VPI). We hypothesized that FLJ rinsing could reduce inflammation (aMMP‐8 and BOP) and microbial load

Streptococcal Infections

, 2009
The streptococci are a large heterogeneous group of gram-positive spherically shaped bacteria widely distributed in nature. They include some of the most important agents of human disease as well as members of the normal human flora. Some streptococci have been associated mainly with disease in animals, while others have been domesticated and used for ...

Gromomycins: An Unprecedented Class of Triterpene Antibiotics Produced by a Novel Biosynthetic Pathway

Angewandte Chemie, EarlyView.
Gromomycins represent a novel class of pentacyclic triterpene antibiotics with a unique biosynthetic pathway independent of the squalene route. These compounds exhibit potent activity against drug‐resistant Gram‐positive pathogens, including MRSA, and their unprecedented cyclization mechanism provides new insight into bacterial triterpene biosynthesis.
