Encapsulation of Bifidobacterium longum in alginate-dairy matrices and survival in simulated gastrointestinal conditions, refrigeration, cow milk and goat milk [PDF]
, 2018 The aim of this study was to microencapsulate Bifidobacterium longum subsp. infantis CCUG 52486 using the extrusion method in a variety of matrices, namely sodium alginate (SA), sodium alginate-cow milk (SACM), sodium alginate-goat milk (SAGM) and sodium

Nanodiamond Quantum Sensors for Probing Free Radical Biology
Advanced Functional Materials, EarlyView.Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Metal Coated Colloidosomes as Carriers for an Antibiotic
Frontiers in Chemistry, 2018 Colloidosomes are polymer shell microcapsules. They are stable and easy to prepare and have been used to encapsulate drugs for release at specific areas in the body. Traditional polymer shell capsules cannot totally seal drugs, since they are porous, and

Formulation of a live bacterial vaccine for stable room temperature storage results in loss of acid, bile and bile salt resistance [PDF]
, 2008 Live bacterial vaccines have great promise both as vaccines against enteric pathogens and as heterologous antigen vectors against diverse diseases. Ideally, room temperature stable dry formulations of live bacterial vaccines will allow oral vaccination ...

A New Method for Staining Bacterial Capsules.
Experimental Biology and Medicine, 1932 A simple method is described by which a capsule-like structure is readily demonstrated about many bacteria. It is selectively stained pink, in contrast to the blue bacterial bodies. Use is made only of stain and fixative. No artificial steps, like preliminary treatment with serum, etc., designed to render the capsule more readily demonstrable, are ...

Bio-UHPC: analysis of the addition of alginate-sodium capsules with Lysinibacillus sphaericus in ultra-high-performance concrete [PDF]
Revista IBRACON de Estruturas e MateriaisCracks in concrete compromise its mechanical strength and expose its interior, making it more susceptible to the external environment. Ultra-High-Performance Concrete (UHPC) is also susceptible to this situation.

Optimal protection of stabilised dry live bacteria from bile toxicity in oral dosage forms by bile acid adsorbent resins [PDF]
, 2010 We previously found that dried live bacteria of a vaccine strain can be temporarily sensitive to bile acids and suggested that Bile Adsorbing Resins (BAR) can be used in oral vaccine tablets to protect dried bacteria from intestinal bile. Here, we report
