Oral Delivery Systems for Food‐Derived Bioactive Peptides: Enhancing Stability, Bioavailability, and Health Benefits

open access: yesAdvanced Science, EarlyView.
Advanced delivery systems—including nanoparticles, nanoemulsions, liposomes, and hydrogels—protect food‐derived bioactive peptides from gastrointestinal degradation and bitterness. These systems enable pH‐responsive release, enhance intestinal absorption, and improve therapeutic efficacy against oxidative stress, metabolic disorders, cancer, and ...

In Situ Profiling of Nanoscale Strains Uncovers Mechano‐Architectural Predictors of Aging and Osteoarthritis Emergence

open access: yesAdvanced Science, EarlyView.
In situ mechanical loading of osteoarthritis‐prone murine knee joints reveals that spatial alterations in subchondral plate microarchitecture precede cartilage loss and promote a shift from coordinated epiphyseal strain dissipation in healthy joints to focal subchondral strain concentration in osteoarthritis‐prone joints.

Natural Aging of Biomaterials in Ambient and Physiological Environments

open access: yesAdvanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Effect of vanadate ions on the chemical precipitation of hydroxyapatite

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов
Ionic forms of V+5 are promising modifying agents for hydroxyapatite, endowing the biomaterial with increased solubility and antibacterial activity. Formation of vanadate-substituted hydroxyapatites was studied under conditions of precipitation from VO3–,

Thermodynamic Study of Protein Adsorption onto Synthetic Calcium Hydroxyapatites

open access: yesAdsorption Science & Technology, 2005
Thermodynamic parameters have obtained in the present study by measuring the adsorption isotherms of bovine serum albumin (BSA: isoelectric point (iep) = 4.7), myoglobin (MGB: iep = 7.0) and lysozyme (LSZ: iep = 11.1) onto calcium hydroxyapatite (Hap) at

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

open access: yesThe 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,

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Effect of high energy radiation on electrical properties of synthetic bone materials

open access: yesInternational Journal of Ceramic Engineering & Science
Hydroxyapatites have been investigated since past six decades as laser host materials. Because of their important roles in bone and teeth, these have been subjects of recent investigations.

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

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

open access: yesJapanese 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.
