Mixed function oxidation and enzymes: kinetic and structural properties of an oxidatively modified alkaline phosphatase

open access: yes, 1988
No major structural alteration of alkaline phosphatase can be observed in the early stages of enzyme oxidative inactivation by the ascorbate model system.

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

open access: yesAdvanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

HISTOCHEMICAL METHODS FOR ACID PHOSPHATASE

open access: yes, 1956
Results obtained by the PbS method and by the post-coupling method of Rutenburg and Seligman are closely similar. However, there are minor differences which appear to be due partly to the presence of more than one acid phosphatase in the tissues, partly

A Fully Human Engineered Bone Niche With Endogenous Osteoclastogenesis Reveals Osteoclast‐Dependent Osteomimicry in Prostate Cancer Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
A human 3D bone niche integrating osteoblasts and osteoclasts enables co‐culture with prostate cancer cell lines and patient‐derived organoids. The engineered niche (i) models aspects of reciprocal phenotypic regulation between osteoblasts and cancer cells, (ii) captures osteoclast‐enhanced osteomimicry in tumor cells, and (iii) establishes a ...

Natural Biomaterials for Osteochondral Repair: From Source to Strategy

open access: yesAdvanced Healthcare Materials, EarlyView.
Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.

The structure and function of hairs of chaetophorales [PDF]

open access: yes, 1986
A study was carried out on the relationship between hair formation and water chemistry in three genera of Chaetophorales (especially Stigeoclonium).The relationship between environmental chemistry, algal morphology and phosphatase activity for 32 samples

A Dual‐Bioresponsive and Programmable Microneedle Matrix as a Bioinspired Coupler for Orchestrating Diabetic Bone Regeneration

open access: yesAdvanced Materials, EarlyView.
This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

The Effects of Two Species of Daphne, Betulin and Betulinic Acid on Alkaline Phosphatase Activity in Two Human Cancer Cell lines, K562 and MCF-7

open access: yesArmaghane Danesh Bimonthly Journal, 2014
Background & aim: Changes of alkaline phosphatase activity is one of the symptoms of many diseases. The aim of this study was to evaluate the effect of two types of Daphne, Betulin and Betulinic acid, on alkaline phosphatase activity in K562 and MCF-7 ...
