CD44‐Targeting Hydroxyapatite Nanoparticles (HAP) Induce Mitochondrial Dysfunction‐Driven PANoptosis and Immunogenic Cell Death (ICD) via Ca Overload in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
ABSTRACT Colorectal cancer (CRC) remains therapeutically challenging due to high metastasis, recurrence, and immunotherapy resistance driven by tumor microenvironment‐mediated immune evasion. Immunogenic cell death (ICD) offers a promising strategy to reshape the immune microenvironment, yet existing ICD inducers suffer from poor targeting efficiency ...

Statistical design for optimal physical and biomechanical characteristics of biocomposite prostheses

open access: yesScientific African
The mechanical properties of many prostheses are the causes of the stress shielding effect resulting from the imbalance of the prosthesis and human bone, which leads to the premature failure of the prosthesis after installation for bone replacement or ...

Multimaterial Triphasic Scaffold Replicates Enthesis Microenvironment to Modulate Early Cell Responses

open access: yesAdvanced 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 ...

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

open access: yesAdvanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.

Hydroxyapatite Synthesis and Comparison with Commercial Hydroxyapatite

open access: yesJournal 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.

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,

Synthesis of nanohydroxyapatite modified with lanthanum and cerium ions: composition and properties

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов
Lanthanide-doped hydroxyapatite nanoparticles can be used as luminescent labels and become an alternative to organic fluorophores, as they are more stable and have a longer service life.
