PspC was found to bind human complement factor H (FH) by Western blot analysis of D39 (pspC(+)) and an isogenic mutant TRE108 (pspC). We confirmed that PspA does not bind FH, while purified PspC binds FH very strongly. The binding of FH to exponentially growing pneumococci varied among different isolates when analyzed by fluorescence activated cell sorting analysis.

Effect of Extraction Methods and Preheat Treatments on the Functional Properties of Pumpkin Seed Protein Concentrate.
ACS Food Sci Technol
January 2025
Department of Food Engineering, Middle East Technical University, Ankara 06800, Turkey.
This study explores the effect of different extraction methods and preheat treatments in obtaining protein concentrate from pumpkin seed flour. The effects on the yield and functional properties of pumpkin seed protein concentrate (PSPC) were compared alongside microwave and conventional preheating methods using alkali, salt, and enzyme-assisted alkali extraction techniques. Analytical assessments included proximate analysis, soluble protein content, water solubility index (WSI), emulsification activity (EA) and stability (ES), foaming capacity (FC) and stability (FS), and antioxidant activity (AA).

Article Synopsis
- Ozone (O) demulsification has potential for treating emulsion wastewater, but challenges include low mass transfer efficiency and selective oxidation.
- A new composite, MnO/porous spontaneously polarized ceramic (MnO/PSPC), enhances catalytic ozonation (HCO) by utilizing strong interfacial interactions and a self-powered electric field, improving charge transfer.
- The MnO/PSPC composite achieved a 99% demulsification rate for certain emulsions in just 30 minutes, significantly outperforming traditional methods and demonstrating effective performance across multiple cycles.
Challenges for the Implementation of Primary Standard Dosimetry in Proton Minibeam Radiation Therapy.

Article Synopsis
- Spatial fractionation of proton fields in cancer treatment improves sparing of healthy tissue while ensuring tumor control.
- This study demonstrated the use of the National Physical Laboratory's Primary Standard Proton Calorimeter to measure absorbed dose in a proton beam with a specific configuration.
- Results indicated that uncertainty in absorbed dose measurements was mainly due to positioning accuracy, suggesting that reference dosimetry should focus on measuring Dose-Area Product or using SOBP for more reliable outcomes in spatially fractionated fields.
Functionalisation and behaviours of polysaccharides conjugated with phenolic compounds by oxidoreductase catalysis: A review.
Int J Biol Macromol
December 2024
Univ Rouen Normandie, INSA Rouen Normandie, CNRS, PBS UMR 6270, F-76000 Rouen, France. Electronic address:
Polysaccharides have been extensively studied in recent decades. Their conjugation with phenolic compounds of natural origin has demonstrated high added value, not only enhancing certain inherent properties but also introducing new ones. Recently, a sustainable approach utilizing oxidoreductase enzymes (Oxredases) (laccases (Lac), tyrosinases (Tyr) and peroxidases (Per)) has been employed, and interesting progress has been made.

J Thorac Dis

Department of Respiratory Medicine, Chest Unit, Cheyne Wing, King's College Hospital, London, UK.
Chronic cough is a complex disorder that affects up to 5-10% of the general population. It can be challenging to manage as there are few effective treatments, although several novel antitussives are in clinical development. The endpoints used to assess their efficacy in clinical trials should be optimal; most large clinical trials currently use objective measures as the primary outcome, especially cough frequency.
