Antiproliferative properties of oleuropein in human osteosarcoma cells

Moran Jose M , Leal-Hernandez Olga , Canal-Macias Maria L , Lavado-Garcia Jesus M , Roncero-Martin Raul , Aliaga Ignacio , Pedrera-Zamorano Juan D

Background: Cancer is one of the leading causes of death worldwide. Natural products have been regarded as important sources of potential chemotherapeutic agents. In this study, we evaluated the antiproliferative activity of oleuropein, an olive oil compound traditionally found in the Mediterranean diet.Design and Methods: The antiproliferative activity on two human osteosarcoma cell lines (MG-63 and Saos2) was evaluated in vitro using the MTT c...

Diabetes leads to development of osteoporosis. Experimental type 1 diabetes may be induced by a single dose of streptozotocin (STZ), and nicotinamide (NA) administered 15 min before STZ dose-dependently protects against the STZ action. Coffee drinking, apart of its health benefits, is taken into consideration as an osteoporosis risk factor. Data from human and experimental studies on coffee and caffeine effects on the skeletal system are inconsistent. For example, although oth...

Valkama Saara , Viljakainen Heli , Holmlund-Suila Elisa , Rosendahl Jenni , Hauta-alus Helena , Enlund-Cerullo Maria , Helve Otto , Andersson Sture , Makitie Outi

Objectives: The aim of this study was to evaluate the association between the age at onset of walking and bone mineral content (BMC) in healthy 2-year-old children participating in the Vitamin D in Infants Trial (VIDI).Methods: Altogether 253 children (120 girls, 133 boys) with a daily vitamin D3 intake of 10 μg and a sufficient serum 25-hydroxyvitamin D (25-OHD) concentration (>50 nmol/l) were included in the analysis. BMC was measur...

Sex and iron modify fibroblast growth factor 23 concentrations in 1-year-old children

Holmlund-Suila Elisa , Enlund-Cerullo Maria , Valkama Saara , Hauta-alus Helena , Rosendahl Jenni , Helve Otto , Viljakainen Heli , Andersson Sture , Makitie Outi

Objectives: The regulation of fibroblast growth factor 23 (FGF23) metabolism during infancy is inadequately characterized. We previously observed a distinct sex difference in intact FGF23 at 3 months of age. In this study we aimed to further examine the role of sex and iron status in FGF23 metabolism in 1-year-old children.Methods: This was a cross-sectional study including 731 1-year-old Caucasian children participating the Vitamin D intervention in inf...

Legg Calve Perthes disease and growth hormone treatment

Belceanu Alina Daniela , Armasu Ioana , Tirnovan Mirela , Bursuc Anamaria , Cabac Mariana , Crumpei Iulia , Constantinescu Georgiana , Preda Cristina , Ungureanu Maria Christina , Vulpoi Carmen

Background: Current extension in the usage of growth hormone therapy (GHT) has increased the prevalence of bone complications. Legg Calvé Perthes disease (LCPD) is characterized by idiopathic avascular necrosis of the proximal femoral epiphysis. More frequently in boys between 4 and 8 years, LCPD is of unknown ethology. An increased incidence has been stated in case of GH deficiency. There is increasing data that children with LCPD may have a more widespread skeletal diso...

Objectives: Nutrition in childhood is a major factor for healthy living during adulthood. Bone mass is influenced immensely by nutritional intake, especially protein intake which is very important for bone matrix and the integrity of skeletal structure. This study aimed to identify the effects of dietary protein intake on bone mineral density (BMD), bone mineral content (BMC) and performance of children aged 6–12 years old.Methods: A repeated measur...

Next-generation sequence and biomarker levels in the patients with early-onset chronic non-bacterial osteomyelitis from North Caucasian region of Russia

Kostik Mikhail , Makhova Maria , Suspitsin Evgeny , Sokolenko Anna , Zorin Vyacheslav , Isupova Eugenia , Magomedova Shamai , Kostik Inna , Takayanagi Hiroshi , Mushkin Alexander , Imyanitov Evgeny

Objectives: Chronic non-bacterial osteomyelitis (CNO) is a heterogenic group of immune-mediated inflammatory bone diseases with unclear pathogenesis. Only a few genes associated with this condition have identified. The aim of the study was to evaluate the spectrum of mutations in genes associated with primary immunodeficiency syndromes (PIDs) and autoinflammatory diseases (AIDs) in the cohort of patients with early-onset CNO from North Caucasus (Dagestan and Chechnya) and asse...

Foramen magnum stenosis (FMS): neuroradiological aspects before and after cervical decompression in paediatric patients with achondroplasia (ACH)

Allegri Anna Elsa Maria , Di Iorgi Natascia , Severino Mariasavina , Patti Giuseppa , Siri Giulia , Piatelli Gianluca , Fava Daniela , Napoli Flavia , Michelis Beatrice , Maghnie Mohamad

The identification of markers indicative of pathological FMS plays a pivotal role in the prevention of ACH complications.Objective: Identify key cranio-cervical junction neuroradiological features for the surgical choice and for the decompression outcome.Methods: Out of 191 ACH patients, we selected 24 patients before 4 years of age, who performed a first brain MRI and/or CT. Patients were divided into 2 groups: surgically treated ...

Introduction: Optimal vitamin D intake for lactating women remains controversial. We hypothesized that 1200 IU/day (vs 400 IU/day) of vitamin D during breastfeeding will enhance maternal vitamin D status and bone mass.Methods: Healthy mothers after term, singleton delivery were randomized to receive vitamin D3: 1200 IU/day (800+400 IU/day from multivitamins) or 400 IU/day (placebo+400 IU/day from multivitamins) during lactation. Serum 25-hydroxyvitamin D...

Over the past decade, many GWAs and meta-analyses were performed to identify genes and regions involved in bone metabolism and in the osteoporotic phenotypes. Nevertheless, the majority of these GWAS results were not tested at any functional level. This study aims to find and study functional regions in the RANK and RANKL genes that encode well-established proteins in the bone remodeling equilibrium. SNPs, chosen for their location in an evolutionary conserve...
