Pyle's disease is an extremely rare skeletal disorder characterized by a benign course and an autosomal recessive genetic pattern of inheritance. Its causal mutation is still unknown. In the medical literature, fewer than 30 cases have been described to date. We report the case of two female siblings, daughters of consanguineous parents, referred to the radiology department complaining of genu valgum. Laboratory tests showed no other relevant findings. Conventional radiography plain films revealed Erlenmeyer flask deformity in bilateral femorotibial metaphyses, metaphyseal flaring of long bones, and mild sclerosis of the skull base...

BACKGROUND: The head of femur is deformed in subjects with Leg Calve Perthes Disease (LCPD). It may be due to an increase in loads applied on the hip, decrease in hip joint containment and decrease in bone mineral density (BMD) of femur. Unfortunately there is not enough evidence regarding BMD of femur in subjects with LCPD. Therefore, the aim of this study is to evaluate BMD in subjects with Perthes disease. METHOD: Two subjects with LCPD participated in this study...

Hereditary multiple exostoses (HME) is an inherited genetic condition characterized by the presence of multiple exostoses (osteochondromas). MHE is a relatively rare autosomal dominant disorder, mainly caused by loss of function mutations in two genes: exostosin-1 (EXT1) and exostosin-2 (EXT2). These genes are linked to heparan sulfate (HS) synthesis, but the specific molecular mechanism leading to the disruption of the cartilage structure and the consequent exostoses formation is still not resolved. The aim of this paper is to encounter the main aspects of HME reviewing the literature, in order to improve clinical features and evolution, and the metabolic-pathogenetic mechanisms underlying...

With the aim of controlling disease relapse and bone deformation of individual joints, the application of gene therapy in rheumatoid arthritis (RA) has slowly progressed on a trial-and-error basis. Several new therapeutic targets have been identified in preclinical studies in animal models, although a limited number of gene-based clinical trials have been conducted. In this article, we summarize the status of gene therapy for RA by addressing issues related to innovating drug development. More disease- and target-specific preclinical tests are required to overcome the insufficient information regarding pharmacokinetics and toxicokinetics, which are related to safety issues in the field of RA gene therapy...

REVIEW

Loss of skeletal muscle myofibrillar protein with disease and/or inactivity can severely deteriorate muscle strength and function. Strategies to counteract wasting of muscle myofibrillar protein are therefore desirable and invite for considerations on the potential superiority of specific modes of resistance exercise and/or the adequacy of low load resistance exercise regimens as well as underlying mechanisms. In this regard, delineation of the potentially mechanosensitive molecular mechanisms underlying muscle protein synthesis (MPS), may contribute to an understanding on how differentiated resistance exercise can transduce a mechanical signal into stimulation of muscle accretion...

BACKGROUND: Craniopagus parasiticus is rare with an incidence of approximately four to six cases in 10,000,000 births. In our case, the head of the parasitic twin protruded from the temporal area of the normal twin's cranium. The parasitic twin had two deformed lower limbs, of which one was rudimentary, and long bones of the bilateral lower limbs and some pelvic bone. Dissection of the mass of the parasitic twin's body revealed the intestine but no chest organs or abdominal organs. There was a rudimentary labium but no vaginal opening...

Tibial dyschondroplasia (TD) is an important tibiotarsal bone disorder characterized by an avascular and nonmineralized growth plate; it is attributed to abnormal differentiation of chondrocytes and causes lameness. Heat-shock protein 90 (Hsp90) is a proangiogenic factor in animal tissues; however, its gene expression increases in cases of chicken TD. The objective of this study was to evaluate the efficacy of epigallocatechin-3-gallate (EGCG) and apigenin in thiram-induced TD birds; these substances were used because of their Hsp90 inhibitory activities...

OBJECTIVES: This study aims to assess five different cortical screw types using artificial femurs, under equated testing conditions. MATERIALS AND METHODS: We investigated the maximum force needed to cause deformation at screw-bone interface using fourth generation composite femurs by conducting separate pullout tests for each screw type. We normalized obtained results with traditional methods and cross-comparison. To conduct pullout tests dependent on screw dimensions, we eliminated the effect of bicortical bone thickness by equalizing the conditions of screw insertion...

BACKGROUND: Collagenous tissues store, transmit and dissipate elastic energy during mechanical deformation. In skin, mechanical energy is stored during loading and then is dissipated, which protects skin from mechanical failure. Thus, energy storage (elastic properties) and dissipation (viscous properties) are important characteristics of extracellular matrices (ECMs) that support the cyclic loading of ECMs without tissue failure. METHODS: Uniaxial stress-strain measurements on decellularized human dermis have been made and compared to results of a non-destructive technique involving optical coherence tomography (OCT) combined with vibrational analysis...
