1. In commercial layer breeding, extensive gene pools are tested and selected for market requirements which must be anticipated at least five years ahead. Field results confirm a continuous positive genetic trend in egg output and better feed efficiency which can be converted into land savings. 2. Animal welfare and cage-free housing dominate future needs of the market. Nesting behaviour and minimal tendency to develop feather-pecking or cannibalism without beak treatment, are key trait complexes. Stronger shells for longer production cycles without moulting have to be combined with better bones...

Contrast-enhanced sonothrombolysis (CEST) seems to be a safe and promising treatment in acute ischemic stroke. It remains unknown if temporal bone features may influence the efficacy of CEST. We investigated the association between different temporal bone features on admission computed tomography (CT) scan and the outcome in acute ischemic stroke patients included in the randomized Norwegian Sonothrombolysis in Acute Stroke Study (NOR-SASS). Patients diagnosed as stroke mimics and those with infratentorial stroke or with incorrect insonation were excluded...

Background: Physical inactivity is a highly modifiable risk factor for the development of osteoporosis but, due to a lack of research that has precisely and objectively meaured physical activity (PA) relevant to bone, the specific contribution that PA can make to bone health is poorly understood. This study examined whether a more precise measure of PA relelvant to bone was associated with meaures of bone health in pre- and post-menopausal women in UK Biobank. Methods: Time spent at intensities specific to bone health [≥750 milli-gravitational units ( mg ) and ≥1000 mg ] were analysed from raw tri-axial acceleration data averaged over 1-second epochs from 7-day monitoring of habitual PA using accelerometry-based activity monitors (100 Hz; AX3, Axivity, UK) of 1218 pre- and 1316 post-menopausal healthy women...

Carrying weight while walking is a common activity associated with increased musculoskeletal loading, but not all individuals accommodate to the weight in the same way. Different accommodation strategies could lead to different skeletal forces, stimuli for bone adaptation and ultimately bone competence. The purpose of the study was to explore the relationships between calcaneal bone competence and biomechanical accommodation variables measured during weighted walking. Twenty healthy men and women (10 each; age 27...

Ultrasound (US)-guided transversalis fascia plane block (TFPB) was first described by Hebbard as a technique for blockade of T12-L1 nerves. Although this technique appears similar to the quadratus lumborum 1 block, the point of injection is more caudal and anterior, specifically targeting ilioinguinal and iliohypogastric nerves. There are only few published data on US-guided TFPB demonstrating effective postoperative analgesia in iliac crest bone graft harvesting. We report the use of US-guided TFPB in a patient undergoing inguinal herniorrhaphy...

AIMS: A clicky hip is a common referral for clinical and sonographic screening for developmental dysplasia of the hip (DDH). There is controversy regarding whether it represents a true risk factor for pathological DDH. Therefore a 20-year prospective, longitudinal, observational study was undertaken to assess the relationship between the presence of a neonatal clicky hip and pathological DDH. PATIENTS AND METHODS: A total of 362 infants from 1997 to 2016 were referred with clicky hips to our 'one-stop' paediatric hip screening clinic...

Ultrasound signals that pass through cancellous bone may be considered to consist of two longitudinal waves, which are called fast and slow waves. Accurate decomposition of these fast and slow waves is considered to be highly beneficial in determination of the characteristics of cancellous bone. In the present study, a fast decomposition method using a wave transfer function with a phase rotation parameter was applied to received signals that have passed through bovine bone specimens with various bone volume to total volume (BV/TV) ratios in a simulation study, where the elastic finite-difference time-domain method is used and the ultrasound wave propagated parallel to the bone axes...

Periodontitis is a chronic infectious disease for which the fundamental treatment is to reduce the load of subgingival pathogenic bacteria by debridement. However, previous investigators attempted to implement a nuclear factor kappa B (NF-κB) decoy oligodeoxynucleotide (ODN) as a suppressor of periodontitis progression. Although we recently reported the effectiveness of the ultrasound-microbubble method as a tool for transfecting the NF-κB decoy ODN into healthy rodent gingival tissue, this technique has not yet been applied to the pathological gingiva of periodontitis animal models...

INTRODUCTION: Surgical instrumentation is now available to facilitate wound debridement. The 2 primary options involve different energy applications, but both have the potential to spray. The Versajet II (Smith & Nephew, London, UK) utilizes a high-powered water jet to disrupt tissue and remove debris by means of the Venturi effect. The SonicVac (Misonix, Farmingdale, NY) is a direct-contact, low-frequency ultrasound debriding device. It delivers a high-energy ultrasound to a wound surface via a fluid medium, causing bubble cavitation, a physical effect of rapid pressure waves causing bubbles to form and implode that releases mechanical energy...

A 40-year-old man presented to a physician for knee pain when squatting and in resisted knee extension. The initial diagnosis was patellar tendinopathy. Following physical therapy treatment, a sports medicine physician was consulted for a second opinion. Radiography, diagnostic ultrasound, and magnetic resonance imaging were performed, confirming the original diagnosis and revealing Hoffa's fat pad impingement secondary to an ununited ossicle.

BACKGROUND: Hypochondroplasia (HCH; OMIM 146000) is a common autosomal dominant skeletal dysplasia characterized by disproportionate short stature, short extremities, relative macrocephaly, and lumbar lordosis. Because of its clinical and genetic heterogeneity, gene mutational analysis is particularly important in diagnosis and the phenotypes may be ameliorated if diagnosed early. MATERIALS AND METHODS: In this study, we examined a Chinese family with HCH, performed an inductive analysis of their clinical features and radiographic results, and applied targeted exome sequencing (TES) technology to perform a molecular diagnosis...

PURPOSE: Dual-energy X-ray absorptiometry (DXA) is the gold standard technique to measure areal bone mineral density (aBMD) for the diagnosis of osteoporosis. Because DXA relies on the attenuation of photon to estimate aBMD, deposition of bone-seeking metallic elements such as strontium, lead and aluminum that differ in atomic numbers from calcium can cause inaccurate estimation of aBMD. Quantitative ultrasound (QUS), is another technique available to assess bone health by measuring broadband ultrasound attenuation (BUA), speed of sound (SOS) and an empirically derived quantity called stiffness index (SI)...
