Evaluation of Bone Mineral Density and Biochemical Parameters of Bone Metabolism after Treatment with Biofield Energy Treated Vitamin D3 in MG-63 Cells

The aim of this study was to examine the potential of Consciousness Energy Healing based vitamin D3 and DMEM medium on bone health parameters. The test items (viz. vitamin D3 and DMEM), were divided into two parts. One part of each test item was received the Biofield Treatment by Jagdish Singh and those samples were labeled as Biofield Treated (BT) samples, while other parts of each sample were denoted as Untreated Test Items (UT). The test samples were found as safe in tested concentrations by MTT assay. ALP was significantly increased by 130.51%, 84.39%, and 67.51% in UT-DMEM + BT-Test item, BT-DMEM + UT-Test item, and BT-DMEM + BT-Test item, respectively at 1 µg/mL than UT-DMEM + UT-Test item group. Moreover, level of collagen was also significantly enhanced by 117.37% in BT-DMEM + UT-Test item at 100 µg/mL than untreated. Other parameter like collagen was significantly increased by 171.30%, 168.51%, and 110.48% in UT-DMEM + BT-Test item, BT-DMEM + UT-Test item, and BT-DMEM + BT-Test item groups, respectively at 50 µg/mL as compared to untreated. Additionally, level of collagen also elevated by 88.49%, 280.08%, and 63.28% in UT-DMEM + BT-Test item, BT-DMEM + UT-Test item, and BT-DMEM + BT-Test item groups, respectively, at 100 µg/mL compared to untreated. Besides, percent of bone mineralization was distinctly increased by 79.34%, 146.74%, and 162.76% in UT-DMEM + BT-Test item, BT-DMEM + UT-Test item, and BT-DMEM + BT-Test item groups, respectively at 100µg/mL compared to untreated. Overall, Biofield Treated vitamin D3 was significantly improved the bone health parameters and it could be a powerful alternative nutraceutical supplement to combat vitamin D3 deficiency and fight against various bone related problems including rickets, osteomalacia, osteoporosis, osteogenesis imperfect, bone fractures, osteoma, chondrodystrophia fetalis, stress management and prevention, autoimmune and inflammatory diseases, and anti-aging by improving overall health. https://www.trivedieffect.com/the-science/biotech/publication/healers-science/nutraceuticals/evaluation-of-bone-mineral-density-and-biochemical-parameters-of-bone-metabolism-after-treatment-with-biofield-energy-treated-vitamin-d3-in-mg-63-cells/

Evaluation of Bone Mineral Density and Biochemical Parameters of Bone Metabolism after Treatment with Biofield Energy Treated Vitamin D3 in MG-63 Cells

Evaluation of Bone Mineral Density and Biochemical Parameters of Bone Metabolism after Treatment with Biofield Energy Treated Vitamin D3 in MG-63 Cells

Aortic vascular calcification is inversely associated with the trabecular bone score in patients receiving dialysis.

Progressive chronic kidney disease (CKD) confers a marked increase in risk for vascular calcification, cardiovascular disease, fracture and mortality, with likely contributing factors including dysregulated bone metabolism and mineral homeostasis. In general population studies, increased vascular calcification is directly related to mortality and inversely related to bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA). In patients with CKD, abnormalities in turnover, mineralization and bone volume reduce the ability of DXA to predict fracture. The trabecular bone score (TBS) obtained from lumbar spine DXA images, provides a surrogate measure of microarchitectural integrity not captured by BMD. This study aimed to examine the association of the TBS to prevalent abdominal aortic calcification (AAC) in patients with CKD receiving dialysis. We performed a cross-sectional study of dialysis patients awaiting transplantation. All patients underwent laboratory testing, lateral spinal radiographs including the abdominal aorta, DXA imaging and TBS assessment. AAC scores were determined using the Kauppila method. Correlations and linear regression models were used to determine predictors of AAC scores. 146 patients (60% male, mean age 48 ± 13 years) were included, of whom 49% had prevalent calcification with an AAC score ≥ 1. Of those with calcification, the mean AAC score was 7 ± 5.5 and 42 patients had scores ≥ 6, considered to indicate severe AAC. TBS values corresponding to intermediate or high risk for fracture (<1.31) were present in 35% of patients. TBS values correlated inversely to AAC scores (β = -0.206, p = 0.013) and remained significant in multivariable linear regression, adjusting for age, BMI and time on dialysis (-0.160, p = 0.031). There was no significant correlation of AAC scores to any BMD parameter. There is a high prevalence of AAC in relatively young dialysis patients awaiting transplantation and their AAC scores are inversely related to the TBS but not to DXA-derived BMD parameters. In patients with CKD on dialysis, TBS assessment reflects microarchitectural abnormalities of bone not captured by DXA. The inverse relationship of TBS to vascular calcification may provide insights into bone-vascular interactions in CKD.

Effects of high-fat diet on bone mineral density and microarchitecture in LDLR-/-mice

Objective To investigate the effect of high-fat diet on bone calcium content, bone mineral density, and microarchitecture in low density lipoprotein receptor knockout(LDLR-/-) mice. Methods Thirteen LDLR-/- mice aged 11 weeks and 13 sex-age-matched C57BL/6J mice(WT)were divided into WT group with normal diet, WT group with high-fat diet, LDLR-/- group with normal diet, and LDLR-/- group with high-fat diet. All mice were sacrificed at 40 weeks of age and left tibias were harvested to analyze the bone mineral density and bone microarchitecture parameters. The right tibias were sampled for measurement of osteoporogeterin(OPG)and receptor activator of nuclear factor kappa-B ligand(RANKL)mRNA expressions using real-time PCR. Results LDLR-/- and high-fat diet significantly changed bone calcium content, bone microarchitecture parameters, and OPG/RANKL mRNA ratio(P<0.05). Compared with WT mice, LDLR-/-mice with high-fat diet showed a lower bone calcium content, along with correspondingly decreased parameters of bone microarchitecture(P<0.05). Compared with WT mice with normal diet, bone calcium content, tissue bone mineral density, and OPG/RANKL mRNA ratio were decreased in LDLR-/-mice with ordinary diet(P<0.01), while no change of other bone microarchitecture parameters was found. Conclusions High-fat diet results in decreased bone mass and damaged bone microarchitecture in LDLR-/- mice, which may be attributed to the down-regulation of OPG/RANKL mRNA ratio.

Anti-interleukin-6 receptor antibody prevents loss of bone structure and bone strength in collagen-induced arthritis mice

Objective: Rheumatoid arthritis (RA) is a disease that typically induces secondary osteoporosis, which increases the risk of bone fractures. Anti-interleukin-6 (IL-6) receptor antibody is used to treat RA; however, its effect on bone strength is not clear. Therefore, we investigated the influence of MR16-1, an anti-mouse IL-6 receptor antibody, on bone structure and femoral strength in a collagen-induced arthritis (CIA) mouse model.Method: DBA/1J mice were immunized by intradermal injection of bovine type II collagen. MR16-1 was administered intraperitoneally at the same time as immunization. Thirty-five days after the first immunization, bone structure and bone strength were measured by micro-computed tomography and the three-point bending test.Results: In the CIA group, most bone mineral density and bone structure parameters in the foot, femur, and lumbar spine were significantly lower than in the normal group. Moreover, the maximum load of the femoral shaft in the CIA group was significantly lower than in the normal group. MR16-1 treatment significantly prevented the CIA-induced deterioration of bone structure and loss of bone strength.Conclusion: These results suggest that CIA systemically induces a deterioration of bone structure and loss of bone strength, and that IL-6 signalling plays an important role in these processes.

Relationship between glycemic control and OPG gene polymorphisms with lower bone mineral density in patients with type 1 Diabetes mellitus

ABSTRACT The aim of the present study was to investigate the bone mineral density (BMD) of patients with type 1 Diabetes mellitus (T1DM). We also assessed the association between osteoprotegerin (OPG) genetic polymorphisms and BMD. Genotyping was performed for 1181G>C and 163A>G OPG polymorphisms by allelic discrimination in 119 patients with T1DM and 161 normoglycemic (NG) individuals, aged 6 to 20 years old. Glycemic control, serum parameters of bone metabolism and BMD were evaluated. T1DM patients showed low BMD, poor glycemic control and decreased total calcium values when compared to controls (p < 0.05). For all the polymorphisms studied, the genotype and allele frequencies in patients with T1DM were not significantly different from the controls. In patients with T1DM, carriers of OPG 1181CC showed higher concentrations of ionized calcium compared to patients with GG+GC genotypes. These results suggest that low BMD is associated with poor glycemic control in T1DM. Despite the lack of a detected association between OPG polymorphisms and BMD in these patients, the increased ionized calcium in those carrying OPG 1181CC suggests a possible increase in osteoclastogenesis, a conclusion that may be supported by the lower BMD observed in these subjects.

Studies of indirect and direct effects of hypervitaminosis A on rat bone by comparing free access to food and pair-feeding

Background: The most prominent features of hypervitaminosis A in rats are spontaneous fractures and anorexia. Since caloric restriction induces alterations in bone, some effects could be secondary to loss of appetite. To clarify the mechanisms behind vitamin A-induced bone fragility it is necessary to distinguish between direct and indirect effects.Materials and methods: In this study we compared rats fed high doses of vitamin A both with pair-fed controls, which were fed the same amount of chow as that consumed by the vitamin A group to keep food intake the same, and to controls with free access to food.Results: In contrast to the pair-fed animals, rats in the free access group fed high doses of vitamin A for 7 days had 13% lower food intake, 15% lower body weight, and 2.7% shorter femurs compared with controls. In addition, serum biomarkers of bone turnover were reduced. Peripheral quantitative computed tomography of the femurs showed that the bone mineral content, cross sectional area, and periosteal circumference were similarly reduced in the pair-fed and free access groups. However, bone mineral density (BMD) and cortical parameters were only significantly decreased in the free access group.Conclusions: Our data indicate that the major direct short-term effect of high doses of vitamin A on rat bone is a reduced bone diameter, whereas the effects on bone length, serum biomarkers of bone turnover, BMD, and bone cortex appear to be mainly indirect, caused by a systemic toxicity with loss of appetite, reduced food intake, and general effects on growth.

Retinol‐binding protein 4 is positively associated with bone mineral density in patients with type 2 diabetes and osteopenia or osteoporosis

This study intends to study the association between serum retinol binding protein 4 (RBP4), bone mineral density (BMD) and other bone metabolic-related parameters in type 2 diabetic patients older than 50 years, with or without osteopenia or osteoporosis. Patients (n = 274 cases) with type 2 diabetes, hospitalized in the Endocrinology Department of Yantai Yuhuangding Hospital from December 2015 to March 2017, were enrolled in the study. The bone mineral density (BMD) was recorded by the dual-energy X-ray absorptiometer, and patients were divided into normal bone mineral density (148 cases), osteopenia (93 cases) and osteoporosis (33cases) groups. The serum adipokine RBP4 and other biomarkers were determined accordingly. Serum RBP4, body weight, calcium and body mass index (BMI) demonstrated a positive correlation with BMD at all tested body sites in osteopenia and osteoporosis groups compared with normal bone mineral density group. In contrast, age, duration of diabetes and alkaline phosphatase (ALP) were inversely correlated with BMD at all tested body sites. In nonadjusted analyses, age, gender, duration of diabetes and ALP were inversely associated with BMD at the femoral neck, total hip and lumbar spine, while body weight, BMI and RBP4 were positively associated with BMD at all sites. In multiple regression analyses, adjusted for age, weight, BMI and other bone-related factors, a graded stepwise positive association between serum RBP4 and BMD was shown, at all sites. Serum RBP4 was positively associated with BMD at all sites after adjustments for other factors in osteopenia and osteoporosis groups compared with normal bone mineral density group of type 2 diabetic patients.

Recipient rs1045642 Polymorphism Is Associated With Office Blood Pressure at 1-Year Post Kidney Transplantation: A Single Center Pharmacogenetic Cohort Pilot Study.

Background: Corticosteroids are associated with reduced bone mineral density (BMD), as well as water and salt retention, leading to hypertension. They are substrates for P-glycoprotein, a protein coded by the highly polymorphic ABCB1 gene. We hypothesized that one ABCB1 polymorphism, rs1045642, is associated with blood pressure and BMD parameters at 1-year post kidney transplantation (KT).Methods: Rs1045642 was genotyped using pyrosequencing in 40 KT recipients. Both dominant (CC vs. CT + TT) and codominant (CC vs. CT vs. TT) genetic models (analysis of variance from linear regressions) were adjusted for confounding variables (age, sex, type of nephropathy, glomerular filtration rate, and corticosteroid use at 1 year).Results: Rs1045642 genotypes were significantly associated with systolic (SBP) and diastolic (DBP) blood pressure 1-year post-transplantation, independent of the genetic model used (adjusted codominant model: SBP p-value = 0.015, DBP p-value = 0.038; adjusted dominant model: SBP p-value = 0.003, DBP p-value = 0.011). A non-statistically significant trend was observed for an association between rs1045642 and BMD change at 1-year post-KT.Conclusions: Rs1045642 is significantly associated with higher BP 1 year after KT. Further investigations are necessary to confirm the role of rs1045642 in corticosteroid-related adverse effects.

3-T MR Imaging of Proximal Femur Microarchitecture in Subjects with and without Fragility Fracture and Nonosteoporotic Proximal Femur Bone Mineral Density.

Purpose To determine if 3-T magnetic resonance (MR) imaging of proximal femur microarchitecture can allow discrimination of subjects with and without fragility fracture who do not have osteoporotic proximal femur bone mineral density (BMD). Materials and Methods Sixty postmenopausal women (30 with and 30 without fragility fracture) who had BMD T scores of greater than -2.5 in the hip were recruited. All subjects underwent dual-energy x-ray absorptiometry to assess BMD and 3-T MR imaging of the same hip to assess bone microarchitecture. World Health Organization Fracture Risk Assessment Tool (FRAX) scores were also computed. We used the Mann-Whitney test, receiver operating characteristics analyses, and Spearman correlation estimates to assess differences between groups, discriminatory ability with parameters, and correlations among BMD, microarchitecture, and FRAX scores. Results Patients with versus without fracture showed a lower trabecular plate-to-rod ratio (median, 2.41 vs 4.53, respectively), lower trabecular plate width (0.556 mm vs 0.630 mm, respectively), and lower trabecular thickness (0.114 mm vs 0.126 mm) within the femoral neck, and higher trabecular rod disruption (43.5 vs 19.0, respectively), higher trabecular separation (0.378 mm vs 0.323 mm, respectively), and lower trabecular number (0.158 vs 0.192, respectively), lower trabecular connectivity (0.015 vs 0.027, respectively) and lower trabecular plate-to-rod ratio (6.38 vs 8.09, respectively) in the greater trochanter (P < .05 for all). Trabecular plate-to-rod ratio, plate width, and thickness within the femoral neck (areas under the curve [AUCs], 0.654-0.683) and trabecular rod disruption, number, connectivity, plate-to-rod ratio, and separation within the greater trochanter (AUCs, 0.662-0.694) allowed discrimination of patients with fracture from control subjects. Femoral neck, total hip, and spine BMD did not differ between and did not allow discrimination between groups. FRAX scores including and not including BMD allowed discrimination between groups (AUCs, 0.681-0.773). Two-factor models (one MR imaging microarchitectural parameter plus a FRAX score without BMD) allowed discrimination between groups (AUCs, 0.702-0.806). There were no linear correlations between BMD and microarchitectural parameters (Spearman ρ, -0.198 to 0.196). Conclusion 3-T MR imaging of proximal femur microarchitecture allows discrimination between subjects with and without fragility fracture who have BMD T scores of greater than -2.5 and may provide different information about bone quality than that provided by dual-energy x-ray absorptiometry. © RSNA, 2018.

Dietary flavonoid kaempferol inhibits glucocorticoid-induced bone loss by promoting osteoblast survival.

Kaempferol, a dietary flavonoid found in fruits and vegetables, has been reported to reverse osteopenic condition in ovariectomized rats. Because kaempferol is endowed with osteogenic activity, the aim of this study was to determine whether it has a beneficial effect on glucocorticoid (GC)-induced bone loss. Adult female rats were divided into four groups as control (vehicle; distilled water), methylprednisolone (MP; 5 mg•kg•d, subcutaneously), MP + kaempferol (5 mg•kg•d, oral), and MP + human parathyroid 1-34 (30 µg/kg, 5 times/wk, subcutaneously) and treated for 4 wk. To study the antagonizing effect of kaempferol on GC-induced inhibition of fracture healing, drill-hole injury was performed on control and GC-treated rats. An oral dose of kaempferol was given for 14 d to observe the effect on callus formation at the site of injury. After treatment, bones were collected for further analysis. GC was associated with a decreased bone mineral density and impaired bone microarchitecture parameters. Consumption of kaempferol induced bone-sparing effects in GC-induced osteopenic condition. Additionally, improved callus formation at site of drill injury in femur diaphysis was observed with kaempferol consumption in animals on GC. Consistent with the in vivo data, kaempferol elicited a higher expression of osteogenic markers in vitro and antagonized the apoptotic effect of dexamethasone on calvarial osteoblasts. These results suggested that kaempferol reduced GC-induced bone loss and enhanced bone regeneration at fractured site, thus emphasizing the positive role of flavonoids on bone health.

Bone Strength in Growing Rats Treated with Fluoride: a Multi-dose Histomorphometric, Biomechanical and Densitometric Study.

Bone deformation and fragility are common signs of skeletal fluorosis. Disorganisation of bone tissue and presence of inflammatory foci were observed after fluoride (F-) administration. Most information about F- effects on bone has been obtained in adult individuals. However, in fluorosis areas, children are a population very exposed to F- and prone to develop not only dental but also skeletal fluoroses. The aim of this work was to evaluate the bone parameters responsible for the effect of different doses of F- on fracture load of the trabecular and cortical bones using multivariate analysis in growing rats. Twenty-four 21-day-old Sprague-Dawley rats were divided into four groups: F0, F20, F40 and F80, which received orally 0, 20, 40 or 80μmol F-/100g bw/day, respectively, for 30days. After treatment, tibiae were used for measuring bone histomorphometric and connectivity parameters, bone mineral density (BMD) and bone cortical parameters. The femurs were used for biomechanical tests and bone F- content. Trabecular bone volume was significantly decreased by F-. Consistently, we observed a significant decrease in fracture load and Young's modulus (YM) of the trabecular bone in F--treated groups. However, cortical bone parameters were not significantly affected by F-. Moreover, there were no significant differences in cortical nor trabecular BMD. Multivariate analysis revealed a significant correlation between the trabecular fracture load and YM but not with bone volume or BMD. It is concluded that when F- is administered as a single daily dose, it produces significant decrease in trabecular bone strength by changing the elasticity of the trabecular bone.

Analysis of Circulating Mediators of Bone Remodeling in Prader-Willi Syndrome.

We tested the hypothesis that the levels of bone remodeling mediators may be altered in Prader-Willi syndrome (PWS). We assessed RANKL, OPG, sclerostin, DKK-1 serum levels, and bone metabolism markers in 12 PWS children (7.8 ± 4.3years), 14 PWS adults (29.5 ± 7.2years), and 31 healthy controls matched for sex and age. Instrumental parameters of bone mineral density (BMD) were also evaluated. Lumbar spine BMD Z-scores were reduced in PWS children (P < 0.01), reaching osteopenic levels in PWS adults. PWS patients showed lower 25(OH)-vitamin D serum levels than controls (P < 0.001). Osteocalcin was increased in PWS children but reduced in adults respect to controls (P < 0.005 and P < 0.01, respectively). RANKL levels were higher in both pediatric and PWS adults than controls (P < 0.004), while OPG levels were significantly reduced (P < 0.004 and P < 0.006, respectively). Sclerostin levels were increased in children (P < 0.04) but reduced in adults compared to controls (P < 0.01). DKK-1 levels did not show significant difference between patients and controls. In PWS patients, RANKL, OPG, and sclerostin significantly correlated with metabolic and bone instrumental parameters. Consistently, with adjustment for age, multiple linear regression analysis showed that BMD and osteocalcin were the most important predictors for RANKL, OPG, and sclerostin in children, and GH and sex steroid replacement treatment in PWS adults. We demonstrated the involvement of RANKL, OPG, and sclerostin in the altered bone turnover of PWS subjects suggesting these molecules as markers of bone disease and new potential pharmacological targets to improve bone health in PWS.

Body composition and circulating estradiol are the main bone density predictors in healthy young and middle-aged men.

Current fracture risk assessment options in men call for improved evaluation strategies. Recent research directed towards non-classic bone mass determinants have often yielded scarce and conflicting results. We aimed at investigating the impact of novel potential bone mass regulators together with classic determinants of bone status in healthy young and middle-aged men. Anthropometric measurements, all-site bone mineral density (BMD) and body composition parameters assessed by dual-energy X-ray absorptiometry and also serum concentrations of (1) the adipokines leptin and resistin, (2) vitamin D and parathormone (PTH), (3) sex hormone binding globulin (SHBG), total testosterone and estradiol (free testosterone was also calculated) and (4) C-terminal telopeptide of type I collagen (CTx) were obtained from 30 apparently healthy male volunteers aged 20-65years enrolled in this cross-sectional study. Only lean mass (LM) and total estradiol independently predicted BMD in men in multiple regression analysis, together explaining 49% (p≤0.001) of whole-body BMD variance. Hierarchical regression analysis with whole-body BMD as outcome variable demonstrated that the body mass index (BMI) beta coefficient became nonsignificant when LM was added to the model. Adipokines, fat parameters, testosterone (total and free), SHBG, PTH and vitamin D were not independently associated with BMD or CTx. The present study shows that LM and sex hormones-namely estradiol-are the main determinants of bone mass in young and middle-aged men. The effects of BMI upon BMD seem to be largely mediated by LM. Lifestyle interventions should focus on preserving LM in men for improved bone outcomes.

Is Sarcopenia a Potential Risk Factor for Distal Radius Fracture? Analysis Using Propensity Score Matching.

BackgroundCases of low-energy-induced distal radius fracture (DRF) are increasing. Sarcopenia is considered to be an independent risk factor for fragility fractures. We compared body appendicular lean muscle mass (ALM) and bone mineral density (BMD) in patients with DRF and a comparable control population. This study aimed to investigate the correlation between skeletal muscle mass and DRF.MethodsWe performed a retrospective review of patients diagnosed with fragility DRF. The DRF group included 87 patients treated at our institute. The control group comprised data for 87 individuals in the general population from among 2,124 selected using nearest-neighbor propensity scoring, based on age, weight, height, and body mass index. All medical conditions and past history were also compared between the two groups.ResultsThe relative overall ALM, combining arm and leg lean body mass divided by height squared, was not significantly different (DRF group, 6.093 kg/m2; controls, 5.945 kg/m2). T-score, a parameter of BMD, was significantly different between groups (DRF, −2.42; controls, −2.05). The proportion of patients with osteoporosis was significantly different (DRF, 44 [50.6%] vs. control, 29 [33.3%], respectively).ConclusionsPatients with DRF did not have significantly lower average lean body mass. BMD was significantly lower in patients with DRF than in controls.

Evaluation of Bone Mineral Density and Biochemical Parameters of Bone Metabolism after Treatment with Biofield Energy Treated Vitamin D3 in MG-63 Cells

The aim of this study was to examine the potential of Consciousness Energy Healing based vitamin D3 and DMEM medium on bone health parameters. The test items (viz. vitamin D3 and DMEM), were divided into two parts. One part of each test item was received the Biofield Treatment by Jagdish Singh and those samples were labeled as Biofield Treated (BT) samples, while other parts of each sample were denoted as Untreated Test Items (UT). The test samples were found as safe in tested concentrations by MTT assay. ALP was significantly increased by 130.51%, 84.39%, and 67.51% in UT-DMEM + BT-Test item, BT-DMEM + UT-Test item, and BT-DMEM + BT-Test item, respectively at 1 µg/mL than UT-DMEM + UT-Test item group. Moreover, level of collagen was also significantly enhanced by 117.37% in BT-DMEM + UT-Test item at 100 µg/mL than untreated. Other parameter like collagen was significantly increased by 171.30%, 168.51%, and 110.48% in UT-DMEM + BT-Test item, BT-DMEM + UT-Test item, and BT-DMEM + BT-Test item groups, respectively at 50 µg/mL as compared to untreated. Additionally, level of collagen also elevated by 88.49%, 280.08%, and 63.28% in UT-DMEM + BT-Test item, BT-DMEM + UT-Test item, and BT-DMEM + BT-Test item groups, respectively, at 100 µg/mL compared to untreated. Besides, percent of bone mineralization was distinctly increased by 79.34%, 146.74%, and 162.76% in UT-DMEM + BT-Test item, BT-DMEM + UT-Test item, and BT-DMEM + BT-Test item groups, respectively at 100µg/mL compared to untreated. Overall, Biofield Treated vitamin D3 was significantly improved the bone health parameters and it could be a powerful alternative nutraceutical supplement to combat vitamin D3 deficiency and fight against various bone related problems including rickets, osteomalacia, osteoporosis, osteogenesis imperfect, bone fractures, osteoma, chondrodystrophia fetalis, stress management and prevention, autoimmune and inflammatory diseases, and anti-aging by improving overall health.

ASSESSMENT OF MORPHOFUNCTIONAL CHANGES IN ELDERLY WOMEN PERFORMING NORDIC WALKING EXERCISE

Aim: the purpose of the research was an assessment of increased physical activity influence on selected elements of elderly women biological condition. Basic procedures: the research material consisted of measurement data of 80 elderly women that were divided into two grups: active (n=31) which participated in a health training, and control (n=49). We measured: basic somaic features, BMI, WHR, BMD and functional physical fitness. Results: analysed parameters of bone mineral density were slightly better of the physically active women in comparison to the unactive women. During analysis of physical fitness tests, active achieved decidedly higher results, which indicates positive influence of the nordic walking health training on functional physical fitness of elderly women. Conclusions: Utilised health training was an optimal stimulus for the examined women – their functional physical fitness and BMD improved considerably. No similar changes were noted in the control group

Bone turnover marker determinants in young women: results from the Safe-D study.

Background Bone turnover markers (BTMs) may provide insight into bone health in young women, but have been little studied in this demographic. We aimed to explore the association between body composition, hormonal contraception, bone mineral density and biochemical parameters and BTMs in young women. Methods Participants were community-dwelling females aged 16-25 years, living in Victoria, Australia. Carboxy-terminal cross-linking telopeptide of type 1 collagen (CTX) and total procollagen type 1 N-propeptide (P1NP) were analysed on the Roche Elecsys automated analyzer. A total of 305 were evaluated, after excluding participants with medical conditions or medications (except hormonal contraceptives), which may affect bone metabolism. Results Median (Q1, Q3) BTM values were 540 (410, 690) ng/L for CTX and 61.7 (46.2, 83.7) µg/L for P1NP. Serum CTX and P1NP were inversely associated with chronological age ( P < 0.001), transferrin ( P < 0.020) and serum dehydroepiandrosterone sulphate concentration ( P < 0.001). BTM values were up to 22% lower in combined oral contraceptive (COC) pill users ( P < 0.001). Serum CTX was inversely associated with per cent body fat ( P = 0.009) and tibial cortical volumetric bone mineral density (vBMD; P = 0.003). Serum P1NP concentrations were 23 µg/L higher in participants who reported using an osteopath in the previous year ( P = 0.007). Conclusions These data suggest that BTMs are influenced by age, COC use, body composition, iron status and hormonal profiles. Higher CTX values were associated with lower tibial cortical vBMD. Examining BTMs in relation to interventions aimed at improving bone health in young women is warranted.

Circulating Irisin Is Reduced in Male Patients with Type 1 and Type 2 Myotonic Dystrophies.

Myotonic dystrophies (DM) are dominantly inherited muscle disorders characterized by myotonia, muscle weakness, and wasting. The reasons for sarcopenia in DMs are uncleared and multiple factors are involved. Irisin, a positive hormone regulator of muscle growth and bone, may play a role. To investigate (1) circulating irisin in a series of DM1 and DM2 male patients compared with healthy controls and (2) the relationships between irisin and anthropometric, metabolic and hormonal parameters. This is a cross-sectional study. Fasting blood samples for glucometabolic, gonadic, bone markers, and irisin were collected from 28 ambulatory DM1, 10 DM2, and 23 age-matched healthy male subjects. Body composition and bone mineralization [bone mineral density (BMD)] were measured by DEXA. Echocardiographic assessment and visceral adiposity, namely, liver and epicardial fat, were investigated by ultrasound. Irisin released from cultured myotubes derived from 3 DM1, 3 DM2, and 3 healthy donors was assayed. Plasma irisin levels were definitely lower in both DM1 and DM2 patients than in controls with no difference between DM1 and DM2. Irisin released from DM1 and DM2 myotubes was similar to that released from myotubes of the non-DM donors, though diabetic DM2 myotubes released more irisin than DM1 myotubes. There was no correlation between irisin and muscle strength or lean mass in both DM1 and DM2 patients. In DM1 patients, plasma irisin levels correlated negatively with oxygen consumption and positively with insulin resistance, while in DM2 patients plasma irisin levels positively correlated with fat mass at arms and legs levels. No correlation with visceral fat, left ventricular mass, and gonadal hormones could be detected. In both DM1 and DM2 patients, legs BMD parameters positively correlated with plasma irisin levels. Plasma irisin is reduced in both DM1 and DM2 male patients likely reflecting muscle mass reduction. Moreover, insulin resistance may contribute to modulation of plasma irisin in DM1 patients. The irisin-mediated cross talk muscle-adipose tissue-bone may be active also in the male myotonic dystrophies' model.

Circulating osteoprotegerin in postmenopausal osteoporotic women: marker of impaired glucose regulation or impaired bone metabolism.

Osteoprotegerin (OPG) is closely related to insulin resistance and bone remodeling. However, no studies have examined the role of OPG in postmenopausal women with coexistent impaired glucose and bone regulation. The present study investigated the relationship of OPG to glucose homeostasis and insulin resistance in postmenopausal osteoporotic women with different types of glucose tolerance. In all, 114 postmenopausal osteoporotic women were divided into three groups according to glucose tolerance status: 51 with normal glucose tolerance (NGT, group 1), 31 with impaired glucose tolerance (IGT, group 2), and 32 with type 2 diabetes mellitus (DM, group 3). Study participants were evaluated for metabolic parameters, OPG, Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), and bone mineral density parameters. The OPG levels differed significantly across groups and increased from group 1 to group 3 in a continuous fashion (analysis of variance, P < 0.0001). In post-hoc analysis, OPG was significantly lower in osteoporotic women with NGT, than participants with IGT and DM (P < 0.05 and P < 0.0001, respectively). OPG was positively associated with HOMA-IR (P < 0.0001). No association between serum OPG levels and measures of BMD was observed. In a multiple regression analysis, OPG emerged as an independent predictor of HOMA-IR even after controlling for age, body mass index, and creatinine. OPG is significantly higher in postmenopausal osteoporotic women with impaired glucose regulation (IGT and DM) than women with NGT. OPG was independently associated with insulin resistance assessed by HOMA-IR. Thus, measurement of OPG may potentially be considered as a prediabetic state screening in postmenopausal osteoporotic women.
