The relationship between fat and bone mass at distinct trabecular and cortical skeletal compartments in a high-fat diet (HFD) model was studied. For this, C57BL/6 mice were assigned to four groups of eight animals each. Two groups, each of males and females, received a standard chow diet while the remaining other two groups received the HFD for a period of(More)
Plants synthesize secondary metabolites, including flavonoids, which play important role during various stresses for their survival. These metabolites are also considered as health-protective components in functional foods. Flavonols, one of the important groups of flavonoids, apart from performing several roles in plants have been recognized as potent(More)
The present study was undertaken to investigate and rationalize the in vitro antiosteoporotic activity of neoflavonoids, isolated from Dalbergia sissoo heartwood. Neoflavonoids were isolated using extensive column chromatography and identified as dalsissooal (1) a new compound and cearoin (2), dalbergin (3), 4-methoxy dalbergion (4), dalbergiphenol (5),(More)
Externally visible body and longitudinal bone growth is a result of proliferation of chondrocytes. In growth disorder, there is delay in the age associated increase in height. The present study evaluates the effect of extract from transgenic tomato fruit expressing AtMYB12 transcription factor on bone health including longitudinal growth. Constitutive(More)
Anti-osteoporotic effects of the newly synthesized coumarin-pyridine hybrids were evaluated in primary cultures of rat calvarial osteoblasts in vitro. Compounds 6a, i, j and k were potent in stimulating osteoblast differentiation and mineralization as assessed by the alkaline phosphatase production and alizarin red-S staining assay, respectively. These(More)
OBJECTIVE This study evaluates the effect of isoflavone cladrin on high-fat diet (HFD)-induced bone loss and adipogenesis. METHODS Thirty-two 4-week-old male C57BL/6J mice were divided into four groups: a standard diet group, a HFD group and HFD group with cladrin (5 and 10 mg/kg per day orally) for 12 weeks. The effect of cladrin on bone(More)
OBJECTIVE Atherogenic diet (AD) and high fat diet (HFD) cause deleterious effect on bone micro-architecture and this phenomenon prompts aortic calcification. This study aims to show the effects of Caviunin β-d-glucopyranoside (CAFG), against bone loss and its associated aortic calcification in presence of AD and HFD challenged diets. METHODS Five groups(More)
OBJECTIVE The aim of this study was to demonstrate the efficacy of extract derived from Spinacia oleracea extract (SOE) in reversing bone loss induced by ovariectomy and bone healing properties in a drill-hole fracture model in rats. METHODS SOE was administered orally for 12 weeks in adult ovariectomized Sprague Dawley rats after inducing osteopenic(More)
Balance between adipocyte and osteoblast differentiation is the key link of disease progression in obesity and osteoporosis. We have previously reported that formononetin (FNT), an isoflavone extracted from Butea monosperma, stimulates osteoblast formation and protects against postmenopausal bone loss. The inverse relationship between osteoblasts and(More)
OBJECTIVE This study aims to evaluate the skeletal effects of dalbergin (DBN), isolated from Dalbergia sissoo heartwood, in ovariectomized (OVx) BALB/c mice, a postmenopausal osteoporosis model of bone loss. METHODS Adult BALB/c mice were used and randomly assigned in to six groups with 6 animals (n=6) in each group: sham (surgery operated without(More)
