Osteoarthritis (OA) is a major clinical problem among the ageing population, yet no disease-modifying treatments currently exist. This issue arises, in part, due to the complex processes occurring in the microenvironment of articular cartilage that lead to osteoarthritic changes. Gaining a better understanding of these processes is crucial in developing a viable therapy for OA. A recent report in Journal of Bone Mineral Metabolism by Janune et al. (J Bone Miner Metab 35:582-597, 2016) suggests a novel role for CCN3 in maintaining the differentiated phenotype of articular cartilage...

Vitamin D deficiency, cardiovascular disease and abnormal bone mineral metabolism are common in chronic kidney disease (CKD). Abnormal bone mineral metabolism has been linked to vascular calcification in CKD. Sclerostin has emerged as an important messenger in cross talk between bone-vascular axis. We analyzed sclerostin in subjects who participated in the randomized, double blind, placebo controlled trial investigating the effect of cholecalciferol supplementation on vascular function in non-diabetic CKD stage G3-4 and vitamin D ≤20ng/ml [CTRI/2013/05/003648]...

BACKGROUND: Although a successful kidney transplant (KTx) improves most of the mineral and bone disorders (MBD) produced by chronic kidney disease (CKD), hyperparathyroidism may persist (pHPT). Current guidelines recommend parathyroidectomy if serum parathormone is persistently elevated 1 year after KTx, because pHPT has been recently associated with poor graft outcomes. However, whether patients with pHPT and adequate renal function are at risk for long-term graft failure is unknown...

This study aimed to explore the relationships of several indicators of cigarette smoking habits (smoking status, pack-years, age at smoking initiation and smoking cessation) with quantitative computed tomographic (QCT)-derived proximal femur bone measures (trabecular vBMD, integral vBMD and the ratio of cortical to total tissue volume (cvol/ivol)) and with subsequent change in these measures over the next five years. A total of 2673 older adults (55.9% women), aged 66-92 years at baseline from the Age, Gene/Environment Susceptibility (AGES)-Reykjavik Study, who had two QCT scans of the hip were studied...

Osteoporosis is a prevalent bone metabolic disease and peripheral blood monocytes represent a major systemic cell type for bone metabolism. To identify the key dysfunctional pathways in osteoporosis, we performed pathway analyses on microarray data of monocytes from subjects with extremely high/low hip bone mineral density. We first performed a traditional pathway analysis for which different pathways were treated as independent. However, genes overlap among pathways will lead to "crosstalk" phenomenon, which may lead to false positive/negative results...

RATIONALE: Osteoporosis is common in individuals with chronic obstructive pulmonary disease. Lung-specific factors, including radiographic emphysema, independently associate with low bone mineral density (BMD) in cross-sectional smoking cohorts. However, factors associated with progressive bone loss in smokers are under-studied and largely unknown. OBJECTIVES: To determine the relationship between radiographic emphysema, circulating bone metabolism markers, and pulmonary function and accelerated BMD loss in smokers...

INTRODUCTION: In 2015, 11.9% of people with cystic fibrosis (CF) in the United States had osteopenia, 5.1% osteoporosis, and 0.3% experienced a fracture. Screening for CF-related bone disease starts in childhood, and dual energy x-ray absorptiometry (DXA) is the recommended method. It is unknown whether peripheral quantitative computed tomography (pQCT) can detect deficits earlier than DXA. This study compared pQCT and DXA scans in a group of pre-pubertal children with CF and healthy controls...

Bisphosphonates (BPs) are well established, widely used first-choice drugs for bone-related diseases and are one of the few classes of molecules for selective bone-targeting. Their binding to calcium cations within hydroxyapatite (HA) is a key physico-chemical event taking place on the bone surface. It is the starting point for a cascade of biochemical reactions and cellular effects that lead to the pharmacological activity of BPs. The phenomenon is known for years, yet still its physicochemical nature is not fully understood...

OBJECTIVE: The relationship between decreased bone mineral density (BMD) and chronic kidney disease (CKD) is controversial. The associations among metabolic syndrome (MetS), serum uric acid and CKD are also unclear. We aimed to investigate the relationship between decreased BMD, MetS, serum uric acid and CKD in a general population. METHODS: A total of 802 subjects who visited a medical center in Southern Taiwan and underwent a BMD measured by dual-energy X-ray absorptiometry (DEXA) during a health examination were enrolled in this retrospective cross-sectional study...

Inflammatory bowel diseases (IBDs), including both Crohn's disease (CD) and ulcerative colitis (UC), are chronic autoimmune diseases. Both CD and UC have relapsing and remitting courses. Although effective medical treatments exist for these chronic conditions, some patients do not respond to these traditional therapies. Patients are often left frustrated with incomplete resolution of symptoms and seek alternative or complementary forms of therapy. Patients often search for modifiable factors that could improve their symptoms or help them to maintain periods of remission...

Periodontal disease may cause considerable destruction of alveolar bone, periodontal ligaments (PDLs) and cementum and even lead to progressive oral dysfunction. Periodontal tissue regeneration is the ultimate goal of periodontal disease treatment to reconstruct both structures and functions. However, the regenerative efficiency is low, possibly due to the lack of a proper periodontal microenvironment. In this study, we applied an injectable and thermosensitive chitosan/gelatin/glycerol phosphate hydrogel to provide a 3D environment for transplanted stem cells and to enhance stem cell delivery and engraftment...

BACKGROUND AND AIM: Tenofovir and entecavir are nowadays the first-line treatment in hepatitis B virus (HBV)-related cirrhosis. Both drugs were shown to be effective in HBV suppression and well tolerated. The effects of tenofovir on bone mineral density (BMD), however, were shown to worsen the rate of osteoporosis, which is already a common feature in cirrhosis. In contrast, entecavir seems to have no effect on mineral metabolism. The aim of our study was to compare the effects of nucleos(t)ide analogs on bone density in HBV-related cirrhosis...

The SOST gene encodes sclerostin, a C-terminal cysteine knot-like domain containing key negative regulator of osteoblastic bone formation that inhibits LRP5/6-mediated canonical Wnt signaling. Numerous single nucleotide polymorphisms (SNPs) in the SOST locus are firmly associated with bone mineral density (BMD) and fracture in genome-wide association studies (GWAS) and candidate gene association studies. However, the validation and mechanistic elucidation of causal genetic variants, especially for SNPs located beyond the promoter-proximal region, remain largely unresolved...

Intermittent fasting may be an effective intervention to protect against age-related metabolic disturbances, although it is still controversial. Here, we investigated the effect of intermittent fasting on the deterioration of the metabolism and cognitive functions in rats with estrogen deficiency and its mechanism was also explored. Ovariectomized rats were infused with β-amyloid (25-35; Alzheimer's disease) or β-amyloid (35-25, Non-Alzheimer's disease; normal cognitive function) into the hippocampus. Each group was randomly divided into two sub-groups: one with intermittent fasting and the other fed ad libitum: Alzheimer's disease-ad libitum, Alzheimer's disease-intermittent fasting, Non-Alzheimer's disease-ad libitum, and Non-Alzheimer's disease-intermittent fasting...

Cell therapies are promising up-and-coming therapeutic strategies for many diseases. For maximal therapeutic benefits, injected cells have to navigate their way to a designated area, including organ and tissue; unfortunately, the majority of therapeutic cells are currently administered without a guide or homing device. To improve this serious shortcoming, a functionalization method was developed to equip cells with a homing signal. Its application was demonstrated by applying an Azadibenzocyclooctyne-bisphosphonate (ADIBO-BP) and azide paired bioorthogonal chemistry on cells for bone specific homing...
