Exploration and examination of the structural, optical, thermal, and functional attributes of a hydroxyapatite and cobalt ferrite nanocomposite for biomedical utilization

AIP Advances
Hydroxyapatite (Hap) is a cornerstone material in biomedical fields, crucial for bone tissue repair and replacement in the human body. However, its mechanical strength falls short compared to that of natural bone, necessitating enhancements.

Inhibitory effect of bovine milk osteopontin on the initial attachment of Streptococcus mutans

JDS Communications
We investigated the effect of bovine milk osteopontin (OPN) on the initial adhesion of Streptococcus mutans to hydroxyapatite. Hydroxyapatite pellets were immersed in a 5.4 µM OPN solution at 37°C for 30 min.

Hydroxyapatite Synthesis and Comparison with Commercial Hydroxyapatite

Journal of New Results in Science, 2016
Hydroxyapatite HAs is the most commonly used synthetic, inert, and biocompatible material having no organic substance. HA having calcium phosphate in their structures are biomaterials used in injured organs or tissues in human body. These make quick and strong recovery when used in body.

Multimaterial Triphasic Scaffold Replicates Enthesis Microenvironment to Modulate Early Cell Responses

Advanced NanoBiomed Research, EarlyView.
A bioinspired triphasic scaffold integrating 3D printed polycaprolactone and electrospun poly(lactic‐co‐glycolic acid) is developed to replicate the organization of the tendon‐to‐bone enthesis. Cyclic mechanical stimulation induces spatially defined cell morphology and lineage‐related gene expression in human mesenchymal stem cells, highlighting the ...

Application of hydroxyapatite implant and bone-hydroxyapatite implant into hydroxyapatite block reconstructed mandibula.

Japanese Journal of Oral & Maxillofacial Surgery, 1991
Applying apatite implants into apatite blocks reconstructed mandibulae was performed in dogs. Apatite implants (A.I.). 5mm in diameter and 9mm in length, and implant for bone-apatite implants (B.A.T.) 4mm in diameter and 9mm in length were used in this experiment.

Vitamin C‐Assisted Synthesis of Novel Cu‐SSZ‐13 Zeolite and Its High‐Efficiency Performance in Diesel Vehicle NOx Exhaust Purification

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Diesel vehicle‐derived NOx is a major pollutant, and NH3‐SCR with Cu‐SSZ‐13 is the mainstream abatement technology. In this study, vitamin C (Vc) was used as a crystal growth regulator to successfully synthesize Cu‐SSZ‐13‐Vc0.3 via the hydrothermal method. Experimental results demonstrate that the introduction of Vc significantly optimizes the

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Milk: Nature's Unique Nutritional Package

Animal Research and One Health, EarlyView.
ABSTRACT Plant‐based beverages that attempt to mimic milk are increasingly popular with consumers, but there are profound differences in nutritional composition and microstructure compared to milk. A structural nutrition approach is needed to understand the effect on digestibility of microstructures, bioaccessibility and bioavailability of components ...

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK pathways

Arthritis &Rheumatology, Accepted Article.
Introduction Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.
