Multiple treatment strategies have been developed for osteochondral lesions (OCLs) of the talus. The purpose of this retrospective study was to assess retrograde autologous bone marrow cell (BMC) transplantation via core drilling (CD) combined with focused extracorporeal shock wave treatment (ESWT) in undisplaced OCL of the talus. A total of 69 patients with unilateral osteochondral lesions of the talus (Hepple grade I-III) were divided into two groups: 41 patients received combined therapy of ESWT and BMC transplantation (group A), while 28 were administered BMC transplantation alone (group B)...

BACKGROUND: Fibromyalgia (FM) is a chronic, debilitating pain disorder. Dissatisfaction with conventional medicine can lead people with FM to turn to complementary and alternative medicine (CAM). Two previous overviews of systematic reviews of CAM for FM have been published, but they did not assessed for risk of bias in the review process. METHODS: Five databases Medline, Embase, AMED (via OVID), Web of Science and Central were searched from their inception to December 2015...

The article by Savina et al. from the large METASARC database of the French Sarcoma Group (BMC Med 15:78, 2017) provides a wealth of information about the natural history and therapy of patients with metastatic soft tissue sarcomas. The information complements - and in some cases surpasses - that obtained from randomized clinical trials, and should not be overlooked because of its retrospective nature. For rare diseases, retrospective data are often more important than data from randomized trials because of the inherent restrictions on sample size...

BACKGROUND: Despite the long-anticipated possibility of putting sequence alignment on the same footing as statistical phylogenetics, theorists have struggled to develop time-dependent evolutionary models for indels that are as tractable as the analogous models for substitution events. MAIN TEXT: This paper discusses progress in the area of insertion-deletion models, in view of recent work by Ezawa (BMC Bioinformatics 17:304, 2016); (BMC Bioinformatics 17:397, 2016); (BMC Bioinformatics 17:457, 2016) on the calculation of time-dependent gap length distributions in pairwise alignments, and current approaches for extending these approaches from ancestor-descendant pairs to phylogenetic trees...

Lactoferrin (LF), an ~80 kDa iron-binding glycoprotein, modulates many biological effects, including antimicrobial and immunomodulatory activities. Recently, it was shown that LF also regulates bone cell activity, suggesting its therapeutic effect on postmenopausal bone loss. However, a minimal amount is known regarding the effects of recombinant human LF (rhLF) supplementation on bone status in young healthy infants. We found osteoblast cell differentiation was significantly promoted in vitro. Furthermore, treatment of human osteoblast cells with rhLF rapidly induced phosphorylation of p44/p42 mitogen-activated protein kinase (p44/p42 MAPK, ERK1/2)...

In developing countries, anemia and iron deficiency in early childhood are two highly prevalent public health problems. Providing caregivers with a powder containing multiple vitamins and minerals (also known as micronutrient powder or MNP) as a food supplement is a widely used strategy to combat these problems. However, concerns exist around MNP programs with regards to effectiveness and potential negative impact on diarrheal disease prevalence and gut flora. Teshome et al. (BMC Medicine 15:89, 2017) recently tested a MNP with a new iron formulation, iron-EDTA, which has a potentially higher bioavailability and thus requires a lower iron content...

INTRODUCTION: Bone remodeling is a tightly regulated process influenced by chemokines. ACKR2 is a decoy receptor for CC chemokines functioning as regulator of inflammatory response. In this study we investigated whether the absence of ACKR2 would affect bone phenotype and remodeling induced by mechanical loading. METHODS: An orthodontic appliance was placed between incisors and first molar of ACKR2 deficient (ACKR2(-/-)) and C57BL6/J (wild-type/WT) mice. Microtomography, histology and qPCR were performed to evaluate bone parameters, orthodontic tooth movement (OTM), bone cells counts and the expression of ACKR2, bone remodeling markers, CC chemokines and chemokines receptors...

BACKGROUND: Relations between bone parameters, physical exertion and childhood fractures are complex. We aimed to estimate the associations between fracture history and bone mineral content (BMC) and areal density (aBMD) at 7 years of age, by levels of physical activity, as a proxy for trauma frequency. METHODS: We used data collected from 2261 children of the Generation XXI birth cohort, assembled in 2005/6 in Porto, Portugal. At age seven (2012/4), fracture history, time spent per week in active play and sports practice were reported by parents...

Context and objectives: Peak bone mass (PBM) is regarded as the most important determinant of osteoporosis. Growing evidence suggests a role of intrauterine programming in skeletal development. We examined PBM and trabecular bone score (TBS) in adults born preterm with very low birth weight (VLBW) or small for gestational age (SGA) at term compared with term-born controls. Design, setting, participants and outcomes: This follow-up cohort study included 186 men and women (25-28 years); 52 preterm VLBW (≤ 1500g), 59 term-born SGA (< 10th percentile), and 75 controls (>10th percentile)...

In 2014, the editorial board of BMC Medical Ethics came together to devise sections for the journal that would (a) give structure to the journal (b) help ensure that authors' research is matched to the most appropriate editors and (c) help readers to find the research most relevant to them. The editorial board decided to take a practical approach to devising sections that dealt with the challenges of content management. After that, we started thinking more theoretically about how one could go about classifying the field of medical ethics...

Senescence marker protein-30 (SMP30) decreases androgen-independently with aging and is a lactone-hydrolyzing enzyme gluconolactonase (GNL) that is involved in vitamin C biosynthesis. In the present study, bone properties of SMP30/GNL knockout (KO) mice with deficiency in vitamin C synthesis were investigated to reveal the effects of SMP30/GNL and exogenous vitamin C supplementation on bone formation. Mineral content (BMC) and mineral density (BMD) of the mandible and femur of SMP30/GNL KO and wild-type mice at 2 and 3 months of age with or without vitamin C supplementation were measured by dual-energy X-ray absorptiometry...

BACKGROUND: Recombinant expression of toxic proteins remains a challenging problem. One potential method to shield toxicity and thus improve expression of these proteins is to encapsulate them within protein compartments to sequester them away from their targets. Many bacteria naturally produce so-called bacterial microcompartments (BMCs) in which enzymes comprising a biosynthetic pathway are encapsulated in a proteinaeous shell, which is in part thought to shield the cells from the toxicity of reaction intermediates...

We examined the associations between childhood growth and bone properties among women at early old age. Early growth in height predicted greater bone area and higher bone mineral mass. However, information on growth did not improve prediction of bone properties beyond that predicted by body size at early old age. INTRODUCTION: We examined the associations between body size at birth and childhood growth with bone area, bone mineral content (BMC), and areal bone mineral density (aBMD) in early old age...

Among females who require the strategies for preventing osteoporosis, appropriate exercise and sport through all their life are important to increase or maintain bone mass. However, the type of exercise and sport applied to females is different in accordance with the lifecycle. Jumping exercise increases bone mineral content(BMC)in prepubescent children(premenarcheal girls). Bone mineral density(BMD)is higher in adolescent athletes who are engaged in weight-bearing activities. Jumping exercise, muscle strengthening exercise, and weight-bearing plus muscle strengthening exercises increase BMD in young adults and premenopausal women...
