BACKGROUND: The Tridax procumbens extracts (TPE) are known for their ethno-medicinal properties to increase osteogenic functioning in mesenchymal stem cells. Recently, we found that the T. procumbens flavonoids (TPF) significantly suppressed the RANKL-induced osteoclasts differentiation and bone resorption. The TPF also promoted osteoblasts differentiation and bone formation demonstrated by increasing bone formation markers in cultured mouse primary osteoblasts. However, the effects of the TPF on in vivo bone formation remain unclear...

Musk, the dried secretion of the musk pod (sac) of adult male musk deer, has been used as traditional Chinese Medicine (TCM) in China and south-east Asian countries for thousands of years. Due to the anabolic steroid component in this TCM, musk preparations have been included in the list of medical products containing prohibited substances employed for doping by the State Food and Drug Administration of China. The application of musk pod formulation was claimed to be responsible for some adverse analytical findings (AAF) in the 2011 FIFA Women's World Cup...

Photobiomodulation (PBM) and photodynamic therapy (PDT) are two major methods, which use light in medicine and dentistry. PBM uses low-level laser light to induce cell proliferation and activity. In contrast, PDT use laser light combined with a photosensitizer (PS) to cause cell death. Due to similar, not fully understood mechanisms and biphasic response of light, unexpected and complex outcomes may be observed. In the present study, the effect of 635 nm laser light, with power density 50 mW/cm(2), at three different energy densities (0...

BACKGROUND: Prevalence of osteoporosis is increasing both in developed and developing countries. Due to rapid growth in the burden and cost of osteoporosis, worldwide, it seems reasonable to focus on the reduction of fractures as the main goal of treatment. Although, efficient pharmacological agents are available for the treatment of osteoporosis, there still remains a need to more specific drugs with less adverse effects. MAIN BODY: This review article provides a brief update on the pathogenesis, presenting current pharmacological products approved by the US Food and Drug Administration (FDA) or Europe, and also newer therapeutic agents to treat osteoporosis according to the clinical trial data available at PubMed, UpToDate, International Osteoporosis Foundation (IOF), and clinical practice guidelines...

Lipidomics is a new frontier of omics research and offers much promise for new-generation biomarkers for common complex phenotypes such as hyperlipidemia (HL) and cardiovascular diseases (CVDs). HL is a disorder characterized by increased levels of blood lipids and is a well-established risk factor for CVD. Traditional clinical markers for prognosis of hyperlipidemic individuals are inadequate to forecast or diagnose cardiac events. In this expert review, lipidomic profiles from recent HL and CVD studies were compared with the normolipidemic profile prepared from the Standard Reference Material...

Stanozolol is a synthetic heterocyclic steroid with anabolic and androgenic properties, which has been abused by several high-profile professional athletes. Stanozolol is also used in veterinary medicine to increase appetite, cause weight gain and treat certain types of anemia. The detection of stanozolol metabolites in human urine for doping control purposes depends on the analytical method applied. The most commonly applied methods in the World Anti-Doping Agency (WADA)-accredited doping control laboratories are gas chromatography/high-resolution mass spectrometry (GC/HRMS) or gas chromatography-mass spectrometry (GC/MS/MS)...

Titanium implants are widely used on an increasing number of patients in orthopedic and dental medicine. Despite the good survival rates of these implants, failures that lead to important socio-economic consequences still exist. Recently, research aimed at improving implant fixation, a process called osseointegration, has focused on a new, innovative field: systemic delivery of drugs. Following implant fixation, patients receive systemic drugs that could either impair or enhance osseointegration; these drugs include anabolic and anti-catabolic bone-acting agents in addition to new treatments...

Low back pain which is a major cause of disability for people aged between 20 and 50years imposes a serious socio-economic burden. The current focus of regenerative medicine is on identifying molecular markers to facilitate the design of targeted therapeutics. Previously, we have demonstrated that expression of the anti-proliferative interferon-induced protein with tetratricopeptide repeats 3 (IFIT3) and pro-apoptotic insulin-like growth factor-binding protein-3 (IGFBP3), are up-regulated as downstream targets of the inflammatory cytokine interferon α (IFNα) signaling pathway in the human annulus fibrosus (AF)...

Artemisia capillaris has been used to treat jaundice and relieve high liver-heat in traditional medicine. In this study, we found that the administration of a water extract from A. capillaris (WEAC) to the receptor activator of nuclear factor kappa-B ligand (RANKL)-induced bone loss model significantly prevents osteoporotic bone loss, increasing bone volume/trabecular volume by 22% and trabecular number by 24%, and decreasing trabecular separation by 29%. WEAC stimulated in vitro osteoblast mineralization from primary osteoblasts in association with increasing expression of osterix, nuclear factor of activated T cells cytoplasmic 1, and activator protein-1, as well as phosphorylation of extracellular signal-regulated kinase...

Anorexia cancer cachexia syndrome is prevalent in advanced cancer patients, which is featured by anorexia, decreased dietary intake, body weight loss (skeletal muscle mass loss), and is unable to be reversed by routine nutritional support therapy. Up to now, the main mechanisms involved in cancer cachexia include excessive systemic inflammation, which is represented by increased plasma levels of IL-1, IL-6, TNF-alpha, tumor-induced factors, such as PIF and LMF. These factors eventually act on orexigenic and anorexigenicneurons located in the hypothalamus or protein and lipid metabolism of peripheral tissues, which lead to anorexia, decreased dietary intake, enhanced basic metabolism rate and hypercatabolism...

Yiqin Zhou, James H-C Wang
Platelet-Rich Plasma (PRP) has been widely used in orthopaedic surgery and sport medicine to treat tendon injuries. However, the efficacy of PRP treatment for tendinopathy is controversial. This paper focuses on reviewing the basic science studies on PRP performed under well-controlled conditions. Both in vitro and in vivo studies describe PRP's anabolic and anti-inflammatory effects on tendons. While some clinical trials support these findings, others refute them. In this review, we discuss the effectiveness of PRP to treat tendon injuries with evidence presented in basic science studies and the potential reasons for the controversial results in clinical trials...

BACKGROUND: A systemic skeletal disease is characterized by low bone mass and micro-architectural deterioration with a consequent increase in bone fragility and susceptibility to fracture. Asia has the highest increment in the elderly population; therefore, osteoporotic fracture should be a noticeable health issue. The incidence rate of hip fractures in Asia could rise to 45% by the year 2050. Complementary and alternative medicine (CAM) is a group of various medical and health care systems, practices, and products that are not presently considered as part of formal medicine...

The stem cell as the building block necessary for tissue reparation and homeostasis plays a major role in regenerative medicine. Their unique property of being pluripotent, able to control immune process and even secrete a whole army of anabolic mediators, draws interest. While new arthroscopic procedures and techniques involving stem cells have been established over the last decade with improved outcomes, failures and dissatisfaction still occur. Therefore, there is increasing interest in ways to improve the healing response...

Development and maintenance of a vascular network are critical for bone growth and homeostasis; strategies that promote vascular function are critical for clinical success of tissue-engineered bone constructs. Co-culture of endothelial cells (ECs) with mesenchymal stem cells (MSCs) and exposure to 10% cyclic tensile strain have both been shown to regulate osteogenesis in isolation, but potential synergistic effects have yet to be explored. The objective of this study was to expose an MSC-EC co-culture to 10% cyclic tensile strain to examine the role of this mechanical stimulus on MSC-EC behavior...
