Modelling bacteriological water quality in drinking water distribution systems

Water Science and Technology, 1998
Because on-site experimentation raises numerous problems, the study and the modelling of bacterial regrowth phenomena in drinking water distribution systems has been performed using a pipe loop pilot under various operating conditions. As a result, experiments have shown that inlet bacterial counts have little influence on the biofilm behavior which is

Sodium Diclofenac‐Loaded Drug Delivery Microspheres: Impact on Calcium Hydroxide Paste Properties and Biological Response

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated whether the incorporation of sodium diclofenac‐loaded microspheres into a calcium hydroxide paste enhances antibiofilm activity while maintaining physicochemical properties and biocompatibility. Calcium hydroxide paste, calcium hydroxide combined with sodium diclofenac, and calcium hydroxide containing sodium diclofenac ...

Naturally coloured poly(3‐hydroxybutyrate)

Coloration Technology, EarlyView.
Abstract This study reports an innovative approach for producing intrinsically coloured poly(3‐hydroxybutyrate) [P(3HB)] films by incorporating natural dyes—turmeric, paprika, annatto, beetroot and hibiscus—directly into the fermentation medium of Ralstonia solanacearum RS.

Assessment of Refuse Dumpsite Impact on Groundwater Quality: A Case Study from Awotan, Ibadan, Oyo State, Nigeria

Science, Engineering and Technology
Groundwater, an essential freshwater resource, is critical to life and supports various industries. Unrestrained urban expansion and inefficient waste management practices endanger groundwater quality.

Apicectomy and retrograde endodontic treatment for an unerupted mandibular cheek tooth

Equine Veterinary Education, EarlyView.
Summary Apicectomy combined with retrograde endodontic therapy is well documented in human and small animal dentistry, but its application in horses remains limited. This report describes the technique in a 2‐year‐old Warmblood mare with an unerupted, infected mandibular cheek tooth (307) that could not be accessed orally. Clinical examination revealed

Effect of storage on bacteriological quality of borehole water

African Journal of Clinical and Experimental Microbiology, 2005
The effect of storage on the bacteriological quality of water from a borehole was investigated. Water samples drawn from the borehole were stored in covered tap-fitted buckets of different colours at room temperature. Physicochemical parameters (pH and suspended solids contents) as well as bacteriological parameters (total bacterial and total coliform ...

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

A chemo‐enzymatic colorimetric cascade for detecting ethylene glycol contamination

The FEBS Journal, EarlyView.
A chemo‐enzymatic cascade is developed for ethylene glycol (EG) detection. EG is oxidized by GoADH with C1‐mediated cofactor recycling to produce glycolaldehyde (GAL). GAL subsequently reacts with purpald to generate a detectable purple chromophore.

Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

The FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.
