Microbiology of Water and Fluids for Hemodialysis
In hemodialysis, huge amounts of water are used for diluting the concentrates to produce dialysis fluid. The water is produced on site by reverse osmosis units. The chemical and microbiological quality of the water is essential for dialysis patients.

Mineral water: a microbiological approach
The microbiological quality of bottled mineral water of various domestic brands sold in Brazil was investigated, with particular focus on the heterotrophic plate count (HPC). Neither total coliforms nor Escherichia coli were found in any 1.5 L bottle samples. Total coliforms were found in 2.9% of the small bottles, while in 20 L bottles the presence of

A novel dissolving microneedle platform preserves HPV virus‐like particle (VLP) immunogenicity by maintaining structural integrity, crucial for eliciting potent immune responses. Buccal administration induces robust immune response, high neutralizing antibody titers, and durable sterile protection across oral and vaginal mucosal sites.

Microbiological quality of bottled water
Bottled water is now the biggest selling soft drink in Europe (van Musschenbroek, 1995) with sales topping 700 million litres in 1994 in the UK alone (Natural Mineral Water Association, pers comm). As part of a wide ranging UK Department of the Environment Programme to assess possible risks from the consumption of drinking water from all sources, a ...

Imaging pH in a live rabbit at the surface of a sensor‐coated titanium plate using X‐ray excited luminescent chemical imaging (XELCI). A raster scanning X‐ray beam generates radioluminescence from a spot on the sensor, and the luminescence passes through the tissue and is collected at two wavelengths to determine local pH.

Microbiological disinfection of water and air by photocatalysis
This article is aimed at presenting (i) a fundamental research on the efficiency of photocatalysis in water disinfection and (ii) the efficiency of a photocatalytic prototype, developed by Buxair firm, to remove avian influenza virus in air. In water disinfection, two model strains of Escherichia coli (K12 PHL849 and K12 PHL1273) were selected and a ...

This study developed a nitrogen‐strengthened copper‐iron‐zinc (N‐CuFeZn) alloy bioactive dressing integrated with electromagnetic stimulation. The coaxial dressing, made from 0.04 mm filaments with 1120 MPa tensile strength, showed that electromagnetic activation enhanced therapeutic outcomes by increasing VEGF expression, promoting angiogenesis (2.1 ...
