Integrative Computational and Experimental Approaches Reveal the Protective Role of Moderate Caffeine Intake Against Apical Periodontitis Induced Bone Loss

International Endodontic Journal, EarlyView.
ABSTRACT Aim To investigate whether moderate systemic caffeine intake modulates the progression of apical periodontitis (AP) and associated alveolar bone loss, combining in vivo rat experiments with in silico molecular docking to explore potential mechanisms. Methodology Male Wistar rats were randomly assigned to four groups (n = 8 per group): control,

N‐Acetylcysteine Reduces Alveolar Bone Loss and Mitigates Systemic Oxidative Damage in Rats With Apical Periodontitis

International Endodontic Journal, EarlyView.
ABSTRACT Aim This study aimed to evaluate the effects of N‐acetylcysteine (NAC) supplementation in apical periodontitis (AP) induced in rats. Methodology Eighteen male Wistar rats were randomly assigned to three groups: control, AP, and AP plus NAC.

Is the temporomandibular joint affected by rheumatoid arthritis? A comparative investigation with knee arthritis in an experimental rat model

Journal of Anatomy, EarlyView.
Animals were sensitized with mBSA emulsified in CFA/IFA and subsequently received three intra‐articular injections of mBSA into either the TMJ or the knee (once per week). Mechanical hyperalgesia was assessed using electronic von Frey testing after arthritis establishment at 24 h or 7 days following the third intra‐articular injection.

Sorption Isotherm Curves in Dry Extruded Pet Foods: Evaluation and Comparison With the Drying Curve

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Sorption isotherms evaluate water exchange between food and environments with different water activities (aw), providing valuable information on physical changes and susceptibility of deterioration due to lipid oxidation and microbial growth.

Autogenous Demineralized Dentin Graft–Based Strategies With or Without I‐PRF and Metronidazole for Ridge Preservation in Infected Sockets: A Randomized Clinical Trial

Journal of Periodontal Research, EarlyView.
This randomized controlled trial evaluated the efficacy of demineralized dentin graft (DDG) combined with injectable platelet‐rich fibrin (I‐PRF) and metronidazole (MTZ) versus DDG with or without I‐PRF in alveolar ridge preservation (ARP) of infected extraction sockets.

Blended Polypropylene Fibers

Journal of Macromolecular Science, Part A, 1998
The preparation, and especially the dyeability of blended fibers polypropylene and terpolymer acrylonitrile-butadiene-styrene and/or polypropylene and polystyrene, respectively are presented in this paper. Modified polypropylene fibers fix the dyestuffs much better and have lower tenacity according to the amount of the additive.

Bagasse Fiber-Polypropylene Based Composites

Journal of Thermoplastic Composite Materials, 1999
Processing and properties of bagasse fiber-polypropylene composites are reported. Four different chemical treatments of the vegetal fibers were performed in order to improve interface adhesion with the thermoplastic matrix: namely isocyanate, acrylic acid, mercerization, and washing with alkaline solution were applied.

Grafting of polypropylene fibers. II. Electrokinetic properties of grafted polypropylene fibers

Journal of Applied Polymer Science, 1987
Electrokinetic properties of methacrylic acid- and acrylonitrile-grafted polypropylene fibers measured in the presence of cationic dyes are reported. The zeta potential of polypropylene fibers decreases, and the surface charge density along with surface conductivity increases as the concentration of the dyes in the streaming solution increases.

Fractographic characterization of isotactic polypropylene fibers

Microscopy Research and Technique, 2020
AbstractIn this article we present an opto‐thermo‐mechanical characterization of isotactic polypropylene monofilament during failure by fracture. The digital photoelasticity, the two‐beam Pluta polarising interference microscope and the computed tomography are used to provide quantitative data and visual models of the fracture regions of isotactic ...

Special polypropylene fibers

1999
Special types of polypropylene (PP) fibers were developed in order to widen their application. The special fibers may be ranged into the following main groups: • multicomponent fibers containing at least two different polymers; • fibers with changing cross-section geometry (profiled and partly filled); • bioactive fibers.
