Different fields of cancer management consider bone health to be of increasing clinical importance for patients: 1) presence of bone metastases in many solid tumors, 2) use of bone-targeted treatments in the reduction of bone metastasis, 3) effects of cancer treatment on reproductive hormones, critical for normal bone remodeling maintenance. Additionally, bone microenvironment is further complicated by the decline of ovarian sex steroid production and by the related increase in inflammatory factors linked to menopause, which result in accelerated bone loss and increased risk of osteoporosis (OP)...

BACKGROUND: Flurbiprofen which is a non-steroidal anti-inflammatory drug (NSAID), has been safely used for the control of postoperative patient's morbidity after periodontal plastic surgeries requiring palatal graft harvesting, but there is little information on the efficacy of topical use. The aim of the study was to evaluate whether patient pain perception was reduced and patient morbidity was improved by using oral spray of flurbiprofen after palatal graft harvesting. METHODS: Fortyeight patients (21 males and 27 females), scheduled for subepithelial connective tissue graft (SCTG) and free gingival graft (FGG) requiring periodontal plastic surgeries were selected...

Retinal detachment (RD) leads to photoreceptor cell death secondary to the physical separation of the retina from the underlying retinal pigment epithelium. Intensifying photoreceptor survival in the detached retina could be remarkably favorable for many retinopathies in which RD can be seen. BNN27, a blood-brain barrier (BBB)-permeable, C17-spiroepoxy derivative of dehydroepiandrosterone (DHEA) has shown promising neuroprotective activity through interaction with nerve growth factor receptors, TrkA and p75NTR ...

BACKGROUND: Patients with Duchenne muscular dystrophy (DMD) exhibit increased prostaglandin D2 (PGD2 ) expression in necrotic muscle and increased PGD2 metabolites in their urine. In mouse models, inhibiting PGD2 production suppresses muscle necrosis, suggesting a possible intervention through PGD2 -mediated activities. OBJECTIVE: We investigated the involvement of PGD2 and its potential use as a marker of pathological progression in DMD. METHODS: Sixty-one male children with DMD and thirty-five age-matched controls were enrolled in the study...

Spondyloarthritides (SpA) include inflammatory joint diseases with various clinical phenotypes that may also include the axial skeleton and/or entheses. SpA include psoriatic arthritis, reactive arthritis, enteropathic arthritis and ankylosing spondylitis; the latter is frequently associated with extra-articular manifestations, such as uveitis, psoriasis, and inflammatory bowel disease. SpA are associated with the HLA-B27 allele and recognize T cells as key pathogenetic players. In contrast to other rheumatic diseases, SpA affect women and men equally and are not associated with detectable serum autoantibodies...

Dementia is a major international public health problem which looks set to grow as the ageing population increases. Despite large amounts of investment there has been relatively little progress in developing new therapies to combat this. There is a growing body of evidence that both local and systemic inflammation are important in dementia; with cerebral inflammation occurring secondarily to beta-amyloid plaques, raised levels of serum inflammatory molecules and cytokines being present in Alzheimer's disease patients and systemic inflammation being associated with cerebral microvasculature disease in vascular dementia...

BACKGROUND: Sputum induction is an important noninvasive method for analyzing bronchial inflammation in patients with asthma and other respiratory diseases. Most frequently, ultrasonic nebulizers are used for sputum induction, but breath-controlled nebulizers may target the small airways more efficiently. This treatment may produce a cell distribution similar to bronchoalveolar lavage (less neutrophils and more macrophages) and provide deeper insights into the underlying lung pathology...

BACKGROUND: The prothoracic gland (PG), the principal steroidogenic organ of insects, has been proposed as a model for steroid hormone biosynthesis and regulation. RESULTS: To validate the robustness of the model, we present an analysis of accumulated transcriptomic data from PGs of two model species, Drosophila melanogaster and Bombyx mori. We identify that the common core components of the model in both species are encoded by nine genes. Five of these are Halloween genes whose expression differs substantially between the PGs of these species...

Steroid receptor coactivator 3 (SRC-3) is a transcriptional coactivator that interacts with nuclear receptors such as the estrogen receptor and the androgen receptor and several other transcription factors to enhance their effects on target gene expression. SRC-3 plays important roles in many developmental, physiological, and pathologic events, including body growth, mammary gland development, energy homeostasis, inflammatory regulation, and cancer initiation and progression. SRC-3 has been suggested to be involved in host defense against bacterial pathogens...

Nuclear hormone receptors represent a large family of ligand-activated transcription factors that include steroid receptors, thyroid/retinoid receptors, and orphan receptors. Among nuclear hormone receptors, the liver X receptors have emerged as very important drug targets. These receptors regulate some of the most important metabolic functions, and they were also identified as anti-inflammatory transcription factors and regulators of the immune system. The development of drugs targeting liver X receptors continues to be a challenge, but advances in our knowledge of receptor structure and function move us forward, toward achieving this goal...

Recently, we successfully generated a novel detection system for vitamin D receptor (VDR) ligands in vivo and in vitro, using a split-luciferase technique called the LucN-LBD-LucC biosensor that is a chimeric fusion protein of firefly luciferase with the ligand binding domain (LBD) of VDR. In this system, the luciferase light intensity of the LucN-LBD-LucC biosensor was decreased by binding of VDR ligands. Although this system is quite useful for evaluation of VDR ligands in a short time, the sensitivity of the LucN-LBD-LucC biosensor is not high enough...

Counterfeiting and adulteration of pharmaceuticals is a prevalent problem worldwide and represents a major health risk to the population, with anabolic steroids being one of the main classes of drugs consumed and obtained from dubious sources. In this work, we propose the use of the 1 H NMR technique to evaluate formulations containing anabolic steroids, with analysis of 40 samples of anabolic drugs that are used in injectable and capsule forms. The samples analyzed presented the following active ingredients: testosterone propionate, testosterone phenylpropionate, testosterone isocaproate, testosterone decanoate, testosterone cypionate, testosterone undecanoate, stanozolol, drostanolone propionate, trenbolone acetate, oxymetholone, and methandrostenolone...

Although angiotensin-converting enzyme inhibitor-related angioedema is well known, angiotensin II receptor blocker (ARB)-related angioedema has not been extensively studied because of its lower incidence. Therefore, ARB-related angioedema is likely to be overlooked in the clinical setting. We analysed the medical records of adults who had been prescribed ARB and diagnosed with angioedema between 2009 and 2015. All adults over the age of 18 years who were initially administered ARB between 1 January 2009 and 31 December 2015 were selected as participants in this study...
