Polyphenol-rich extract from Wisteria floribunda (Willd.) DC. flowers promotes osteoblast differentiation and bone formation by modulating the mTOR pathway

open access: yesAsian Pacific Journal of Tropical Biomedicine
Objective: To investigate the osteogenic effects of polyphenol-rich extracts from Wisteria floribunda (Willd.) DC. (W. floribunda) flowers and elucidate the underlying mechanisms. Methods: Polyphenolic compounds of W.

Accumulation, localization, and compartmentation of transforming growth factor beta during endochondral bone development. [PDF]

open access: yes, 1988
Endochondral bone formation was induced in postnatal rats by implantation of demineralized rat bone matrix. Corresponding control tissue was generated by implanting inactive extracted bone matrix, which did not induce bone formation.

Rhinologic changes in Wegener's granulomatosis [PDF]

open access: yes, 2002
Twenty-eight patients with a clinical diagnosis of sinonasal Wegener's granulomatosis were referred for imaging during the period 1990-2001. Of these, 10 had clinical symptoms and signs confined to the nose and sinuses and 18 had classical systemic ...

Bone turnover markers, use in osteoporosis

open access: yesBioingeniøren, 2013
Background: Osteoporosis is a chronic skeletal disease causing lowered bone mineral density and an increased risk of fractures. Norway has the highest incidence of osteoporotic fractures in the world. What is the mechanism for osteoporosis, and how do we

Stimulation of Piezo1 by mechanical signals promotes bone anabolism [PDF]

open access: yes, 2019
Mechanical loading, such as caused by exercise, stimulates bone formation by osteoblasts and increases bone strength, but the mechanisms are poorly understood.

Porcine bone scaffolds adsorb growth factors secreted by MSCs and improve bone tissue repair [PDF]

open access: yes, 2017
An ideal tissue-engineered bone graft should have both excellent pro-osteogenesis and pro-angiogenesis properties to rapidly realize the bone regeneration in vivo . To meet this goal, in this work a porcine bone scaffold was successfully used as a Trojan

Re-tuning bone formation [PDF]

open access: yesJournal of Experimental Medicine, 2015
![Figure][1] Insight from Gerard Karsenty Fibrillin-1 (FBN1) is a structural component of microfibrils in the extracellular matrix that plays a role in tissue development. Genetic defects in FBN1 are associated with a number of clinical conditions including systemic sclerosis (SSc)/

NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Effects of aerobic treadmill exercise on the bone turnover in obese male mice

open access: yesFrontiers in Cell and Developmental Biology
IntroductionThis study aims to investigate the effects of aerobic exercise on the bones of obese male mice induced by a high-fat diet and determine the related mechanisms. Results will provide a reference for exercise-related recommendations in the early

Effect of carbohydrate feeding on the bone metabolic response to running [PDF]

open access: yes, 2015
Bone resorption is increased after running, with no change in bone formation. Feeding during exercise might attenuate this increase, preventing associated problems for bone. This study investigated the immediate and short-term bone metabolic responses
