Oscillatory fluid flow enhanced mineralization of human dental pulp cells.
Front Bioeng Biotechnol
January 2025
Department of Preventive Dentistry, Division of Pediatric Dentistry, Faculty of Dentistry, Naresuan University, Phitsanulok, Thailand.
The purpose of this study is to evaluate the optimum frequency of oscillatory fluid flow (OFF) for increasing osteogenesis in human dental pulp cells (DPCs) in an incubating rocking shaker. DPCs from 3 donors were cultured in an osteogenic induction medium (OIM) and mechanical stimulation was applied using an incubating rocking shaker at frequencies of 0 (control), 10, 20, 30, and 40 round per minute (RPM) for 1 h/day, 5 days/week. Cell proliferation was measured using total protein quantification, and osteogenic activity was measured by alkaline phosphatase (ALP) activity, calcium deposition, and collagen production on days 7, 14, and 21 of culture.

Background: Sustainable rural water supply management requires accurate estimations of water consumption and understanding factors influencing consumption. Climate change exacerbates challenges, especially in developing countries with high poverty and limited access to clean water. Ethiopia has the lowest municipal water supply in Africa.

Indian J Orthop
February 2025
Department of Orthopaedics, JSS Medical College, Mysore, 570004 India.
Background: Rickets is a common metabolic bone disease in children, primarily caused by vitamin D deficiency. This study aimed to compare the efficacy of oral weekly vitamin D supplementation and injectable stoss therapy in treating nutritional rickets in Indian children.
Methods: This prospective, randomized, controlled trial was conducted over 18 months at a tertiary care center.
Line-Shifting Triarylmethyl Radicals for Imaging of Enzyme Activity Using Overhauser-Enhanced Magnetic Resonance Imaging: Application to Alkaline Phosphatase.
Chem Biomed Imaging
January 2025
In Vivo Multifunctional Magnetic Resonance Center, Robert C. Byrd Health Sciences Center, West Virginia University, Morgantown, West Virginia 26506, United States.
Enzyme catalytic activities are critical biomarkers of tissue states under physiological and pathophysiological conditions. However, the direct measurement and imaging of enzyme activity remains extremely challenging. We report the synthesis and characterization of the first stable triarylmethyl (TAM) radical substrate of alkaline phosphatase (TAM-ALPs).

Cellulose (Lond)
December 2024
Department of Chemical Engineering, Imperial College London, South Kensington, Exhibition Road, London, SW7 2AZ UK.
Unlabelled: We report a simple procedure to produce carboxylated cellulose nanocrystals (CNCs) from grassy biomass () using a two-step approach consisting of biomass fractionation with a protic ionic liquid followed by oxidation of the resulting cellulose-rich pulps with HO. The impact of the fractionation severity on the composition, structure, size, thermal stability, crystallinity, and degree of polymerization of the CNCs was evaluated. It was found that fractionation severity had a large impact on the pulp purity and its reactivity during the oxidation stage.
