Its genomic architecture enables robust interaction with intestinal epithelial cells, activating specific TLR2-dependent signaling pathways. (2) L. rhamnosus GG is distinguished by its pili-encoding spaCBA cluster, conferring exceptional adhesion capacity that makes it invaluable for competitive exclusion models and biofilm research. The SpaCBA pili enable direct interaction ...
As spring arrives, so does a renewed focus on cleaning, quality, and process validation in pharmaceutical facilities. Whether it’s a routine seasonal turnover or preparation for ramped-up production cycles, spring is a critical time in the pharmaceutical industry for equipment maintenance, cleaning validation, and ensuring product purity. Behind every cleanroom, batch reactor, or ...

Then, researchers imprinted the biofilm with nanomedicines, increasing targeting power without the rejection and other side effects. ...
What is biofilm? Biofilms are defined as communities of micro-organisms attached to a surface, or one another, and encased within a matrix of extracellular polymeric substance (EPS). The EPS makes up the largest component of the biofilm, and in the biological environment is generally composed of polysaccharides, proteins, glycolipids, blood ...
.); Up-scaling; Optimizing operational conditions; Biofilms, etc. The proposed method for sequential treatment relies on environmental-friendly solutions for both applied chemicals and the illumination source. ...
Liposomes Liposomes are a kind of spherical carrier composed of a hydrophilic nucleus and hydrophobic phospholipid bilayer. It has good biofilm property and containment and can promote cell uptake and endosomal escape while avoiding nuclease degradation. ...
Although the exact reason behind this specific connection is still subject to comprehensive ongoing research, a significant amount of attention is being directed to the oral biofilm (an intricate community of billions of bacteria thriving in the mouth), the inflammatory process and the condition of the immune response. Excess Biofilm in the Mouth is the ...
Consequently, bacterial infection is the second leading cause of death in hemodialysis patients with end-stage renal disease.10 Gram-positive Staphylococcus aureus is responsible for the majority of vascular access infections4,11 and subsequently linked to higher rates of patient mortality from serious medical complications including infective endocarditis and osteomyelitis.12 Staphylococci have ...
It is precisely due to this property similar to biofilm that it can be used as an efficient, safe, high bioavailability and other active ingredient carrier. ...
Traditional mechanical therapy using hand instruments have shown limitation in accessing the dental biofilm and calculus, because of their bulk and shape. Lasers have been proposed to solve this limitation as the beam can reach the deepest pockets and grooves. ...

“Classical techniques for determining protein structure, such as the use of x-rays, have had limited success for proteins embedded in biofilms, and there are still many unsolved problems.” Oscar Llorca, leader of the macromolecular complex group of the CNIO DNA damage response group, director of the structural biology program at the center, and co-author of the study, ...
Through the coupling of mechanical extrusion and fluid shear, nanopores that exist transiently on the surface of exosome membrane and do not destroy the biofilm structure are produced, which promotes the entry of exogenous substance molecules from the surrounding solution into the exosome, thus realizing the atraumatic preparation of exosome drug carriers. ...
Are there any fill equipment parts that are very difficult to or are unable to be cleaned that might promote biofilm formation? Is it possible to replace parts that are challenging to clean to reduce the probability of a biofilm forming? Are the correct cleaning techniques being used to prevent biofilms from forming on equipment and facility ...
This can increase the growth of biofilms and free-floating bacteria, including pathogenic bacteria such as Legionella. ...
Abstract: We present an imaging and image analysis approach to quantify both the overall morphology and the spatial distribution of nitrifying guilds in mixed-culture, nitrifying biofilms enriched on K1 carriers. For image acquisition we used optical coherence tomography to non-destructively visualize the three dimensional structure of entire internal cavities and fluorescent in ...
In hospitals, the water distribution system requires special attention since it can be a source of pathogens, including those in the form of biofilms often correlated with resistance of microorganisms to various treatments. ...
Pigment-producing Enterococcus casseliflavus and Staphylococcus aureus seemed to be more resistant against ozone than non-pigmented species of these genera. Furthermore, aggregation or biofilm formation apparently protected bacteria in subsurface layers from inactivation by ozone. ...
Thus, the presented inhibition test provides a simple but robust alternative method to assess antibiotic resistance in biofilms instead of more complex clinical tests. ...
Spatial and temporal dynamics of antibiotic resistance genes in freshwater biofilms from NZ's fourth longest river as it transitioned between low and high intensity farming were examined for 1 year. Polymerase chain reaction was employed to gauge the level of resistance present. Biofilms were screened for 10 genes conferring resistance to antibiotics used ...
