Vascular calcification (VC) is a major contributor of cardiovascular dysfunction in chronic renal failure (CRF). Citrate binds calcium and inhibits the growth of calcium crystals. This present study intends to evaluate the effect of citrate on VC in adenine-induced CRF rats. The rats were randomly divided into five groups: the control group, the citrate control group, model group, model rats with low-dose treatment of citrate (216 mg/kg) and model rats with high-dose treatment of citrate (746 mg/kg). The rats were euthanized at 5 weeks with their blood and aorta in detection...

BACKGROUND: Egg yolk phosvitin, one of the most highly phosphorylated extracellular matrix proteins known in nature, has a strong calcium binding and reducing capacity. Here, we investigated the effects of phosvitin on the osteoblast differentiation and osteogenic gene expression in cultured mouse osteoblastic MC3T3-E1 cells by using alkaline phosphatase (ALP) activity analysis, alizarin red S staining and real-time PCR assay. RESULTS: ALP activity and alizarin red S staining analyses demonstrated no significant difference between differentiating MC3T3-E1 cells cultured in the presence of phosvitin and those cultured in the presence of ascorbic acid after 21 days of differentiation...

Elevated level of blood phosphate (Pi) associated with chronic kidney disease (CKD) is a risk factor of aortic valve calcification. Aortic valve interstitial cells (AVICs) display osteogenic responses to high Pi although the underlying mechanism is incompletely understood. Sox9 is a pro-chondrogenic factor and may play a role in ectopic tissue calcification. Circulating and kidney levels of Klotho are reduced in patients with CKD. We hypothesized that Sox9 mediates high Pi-induced osteogenic responses in human AVICs and that Klotho inhibits the responses...

Attempts to reflect the physiology of organs is quite an intricacy during the tissue engineering process. An ideal scaffold and its surface topography can address and manipulate the cell behavior during the regeneration of targeted tissue, affecting the cell growth and differentiation significantly. Herein, silk fibroin (SF) nanoparticles were incorporated into poly(l-lactic acid) (PLLA) to prepare composite scaffolds via phase-inversion technique using supercritical carbon dioxide (SC-CO2). The SF nanoparticle core increased the surface roughness and hydrophilicity of the PLLA scaffolds, leading to a high affinity for albumin attachment...

Zoledronate produces long-term normalization of biochemical markers in Paget's disease but whether this implies the absence of active disease is unknown. We have determined whether bone scintigraphy, a more sensitive index of disease activity, is also normalized ≥5 years after treatment with zoledronate. A consecutive case series of 11 individuals with Paget's disease treated with zoledronate 5 mg ≥5 years previously is reported. Eight patients received a single zoledronate infusion and were assessed 55-120 months later...

High incidence of osteoporotic fractures emphasizes the necessity of developing effective measures to promote osteogenesis. In our study, we investigated a possible role of MAPK-ERK signaling in the TGF-β-mediated osteoblastic differentiation. Our results indicated that TGF-β activated the MAPK-ERK pathway and inhibited osteogenesis in mesenchymal pluripotent cell line, C3H10T1/2, and preosteoblastic cell line, MC3T3 cells. And the downregulation of MAPK-ERK signaling using pharmacological inhibitor U0126 and RNA interference rescued osteoblast differentiation suppressed by TGF-β, which was confirmed by Alkaline phosphatase (ALP) staining and alizarrn red staining and the enhanced expression of osteogenesic markers...

BACKGROUND AND OBJECTIVE: Diabetes mellitus (DM) is a common disease worldwide. Patients with DM have an increased risk of losing their teeth compared with other individuals. Dental implants are a standard of care for treating partial or full edentulism, and various implant surface treatments have recently been developed to increase dental implant stability. However, some studies have reported that DM reduces osseointegration and the success rate of dental implants. The purpose of this study was to determine the effects of high glucose levels for hard tissue formation on a nano-scale modified titanium surface...

We present a case of a 13 years old boy who was hospitalized with a 10 months history of progressive pain and weakness in his lower extremities. The laboratory tests revealed slightly decreased phosphate and 25-hydroxyvitamin D3, high alkaline phosphatase, normal calcium and parathyroid hormone (PTH). Magnetic resonance imaging (MRI) showed multiple patchy lesions indicating bone destruction in the metaphyses and epiphyses of the left knee. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) revealed a generalized decrease of bone density in axial bones with slightly increased (18)F-FDG metabolism...

Gene delivery to skeletal muscle is a promising strategy for the treatment of muscle disorders and for the systemic secretion of therapeutic proteins. In addition, muscle is an attractive target tissue because it is easily accessible. However, very few synthetic vectors proved capable of surpassing naked DNA mediated muscle gene transfer. In fact, only neutral copolymers, in particular poloxamers, demonstrated capacities to increase transgene expression in skeletal muscles. Here, we studied in vitro and in vivo behaviour of different bile salts...

The fruit of Ligustrum lucidum (FLL, Nuzhenzi in Chinese) is an important traditional medicine, and have attracted significant research attention because of their various biological activities. However, there are few research reports available on the use of FLL as a feed additive in livestock nutrition, particularly in layers. This study was conducted to determine the effects of supplementation of the diet of laying hens with FLL on laying performance, egg quality and blood metabolites. A total of 360 72-week-old hens were allocated to three dietary treatments (eight replications of 15 hens/treatment group) and were fed either a control diet or a diet supplemented with an inclusion level of 0...
