Inherited knee disorders in the Medici family

Donatella Lippi, Marco Matucci-Cerinic, W.R. Alburyc, George M. Weisz, more

The Knee > 2014 > 21 > 1 > 2-5

Reconstructing a medical condition which was existent centuries ago is limited by the lack of contemporaneous evidence-based descriptions in the accounts given by physicians and other observers. Despite these limitations modern paleopathological evidence, supplemented by techniques of historical investigation, have led to the conclusion that males in the Medici family typically suffered from a complex...

York Kiat Tan, HuiHua Li, John C. Allen, Julian Thumboo

Journal of Clinical Ultrasound > 48 > 1 > 14 - 18

Purpose To identify joints commonly exhibiting bone erosions using an extended 36‐joint sonographic (US) examination in patients with rheumatoid arthritis (RA) and to study bone erosion in relation to US‐detected joint inflammation. Methods In this cross‐sectional study, power Doppler (PD) and gray‐scale (GS) joint inflammation scores (semi‐quantitative [0‐3] grading) at each joint recess were...

Factor VIII prophylaxis effects outweigh other hemostasis contributors in predicting severe haemophilia A joint outcomes

Beth Boulden Warren, Linda Jacobson, Christine Kempton, George R. Buchanan, more

Haemophilia > 25 > 5 > 867 - 875

Introduction The Joint Outcome Study (JOS) demonstrated that previously untreated children with severe haemophilia A treated with prophylactic factor VIII (FVIII) concentrate had superior joint outcomes at age 6 years compared to those children treated episodically for bleeding. However, variation in joint outcome within each treatment arm was not well explained. Aim In this study, we sought to...

Detecting joints with erosion(s) in rheumatoid arthritis: a novel individualized-ultrasound method performs better than existing methods

York Kiat Tan, HuiHua Li, John Carson Allen, Julian Thumboo

Japanese Journal of Radiology > 2019 > 37 > 11 > 793-797

Purpose To determine if a novel individualized-ultrasound (IUS) method can detect more joints with erosion(s) in rheumatoid arthritis (RA) patients versus existing methods. Materials and methods The IUS method selects up to 7 or 14 ultrasonographically most inflamed joints whereas existing methods pre-fix 7 or 14 joints for ultrasonography. Using ultrasonography, the mean total inflammatory score...

Ultrasound power Doppler and gray scale joint inflammation: What they reveal in rheumatoid arthritis

York Kiat Tan, HuiHua Li, John Carson Allen, Julian Thumboo

International Journal of Rheumatic Diseases > 22 > 9 > 1719 - 1723

Aim Power Doppler (PD) and gray scale (GS) imaging are commonly employed during ultrasonography in rheumatoid arthritis (RA). While PD vascularity is often regarded as an ultrasound feature of more active joint inflammation, the true clinical significance of GS joint inflammation is less understood. We aimed to gain further insight into ultrasound PD and GS joint inflammation by studying their association...

A low-cycle fatigue approach to predicting shear strength degradation in RC joints subjected to seismic actions

Carmine Lima, Enzo Martinelli

Bulletin of Earthquake Engineering > 2019 > 17 > 11 > 6061-6078

Reinforced concrete (RC) structures realised in earthquake-prone regions are exposed to seismic shakings that may result in significant damage and even lead them to collapse. As well known, high stress concentration occurs at the end of both beams and columns of RC frames, making those members extremely prone to damage. Moreover, beam-to-column joints are particularly sensitive to brittle failure,...

Receiver operating characteristic analysis of ultrasound joint inflammation in relation to structural damage and disease activity in rheumatoid arthritis

HuiHua Li, John Carson Allen, Julian Thumboo, York Kiat Tan

La radiologia medica > 2019 > 124 > 10 > 1037-1042

Objective To investigate whether ultrasound greyscale (GS) and power Doppler (PD) joint inflammation may be useful in identifying rheumatoid arthritis (RA) patients in different states of structural damage and disease activity. Methods In this cross-sectional study utilizing 36-joint ultrasonography, bone erosion was scored dichotomously (1 = yes/0 = no) while GS and PD joint inflammations were...

The differentiating ability of four plasma biomarkers in canine hip dysplasia

Sebastián Cardona‐Ramírez, Catalina López‐Villegas, Raúl F. Silva‐Molano

Veterinary Clinical Pathology > 48 > 2 > 320 - 327

Background The accumulation of cartilage breakdown products in body fluids has been extensively investigated to assess the accuracy of molecular biomarkers from a diagnostic, prognostic, and therapeutic perspective. Nevertheless, to the authors' knowledge, there is a lack of information about spontaneous models of hip osteoarthritis and the differentiating ability of collagen, noncollagen, and inflammatory...

Landslide in parts of southwestern Nigeria

O. A. Bamisaiye

SN Applied Sciences > 2019 > 1 > 7 > 1-12

Landslides represent “structural failures” with great risk to the environment, and this makes the study of the mechanism of formation of landslides very important. Most parts of the Okemesi ridge are inherently dangerous areas, at high risk of sliding. This research is one of the first detailed geological investigations of landslides in this area. This research evaluates the importance of the lithological,...

A. S. Zuev, A. V. Lepeshkin

Russian Engineering Research > 2019 > 39 > 5 > 383-385

To decrease the metal content in the housings of solid-fuel rocket engines, the metallic joint reinforcement may be replaced by plastic components. A device for the production of reinforcement blanks by winding is developed. This system ensures polymerization and machining of the plastic.

Damage and fracture analysis of bolted joints of composite materials based on peridynamic theory

Na-Na Yang, Tian-You Zhao, Ji-Guang Gu, Zhi-Peng Chen

Polish Maritime Research > 2019 > nr 2 > 22--32

It is clear that the advantages of fibre glass-reinforced plastics surpass those of steel, but the failure analysis of composite structures is much more complex than that of isotropic materials as composite materials may fail in a variety of ways. In order to simulate the damage and fracture of bolted joints of fibre reinforced composite, the bond-based peridynamic method suitable for elastic, brittle...

Psoriatic Arthritis: What is Happening at the Joint?

Jennifer Belasco, Nathan Wei

Rheumatology and Therapy > 2019 > 6 > 3 > 305-315

Psoriatic arthritis (PsA) is a heterogeneous and inflammatory disease with diverse clinical manifestations, including psoriasis, nail psoriasis, peripheral joint disease, axial joint disease, enthesitis, and dactylitis. Typically, this varied clinical presentation complicates the clinician’s ability to distinguish PsA from other forms of arthritis. In the synovium of individuals with PsA, upregulation...

Arc-parallel compression in the NW Himalaya: Evidence from structural and palaeostress studies of brittle deformation from the clasts of the Upper Siwalik, Uttarakhand, India

Dripta Dutta, Tuhin Biswas, Soumyajit Mukherjee

Journal of Earth System Science > 2019 > 128 > 5 > 1-20

The sub-Himalayan Upper Siwalik rocks, between the Main Boundary Thrust (MBT) to the north and the Main Frontal Thrust (MFT) to the south, are intensely brittle sheared and jointed. Our field studies around Dehradun (India) furnished at least eight small-scale brittle slip directions, viz., $${\sim }\hbox {top-to-SW/SSW}$$ ∼top-to-SW/SSW (up), top-to-SW/SSW (down), top-to-NE/NNE (up), top-to-NE/ENE...

Morphology, shape variation and movement of skeletal elements in starfish (Asterias rubens)

Lena Schwertmann, Oliver Focke, Jan‐Henning Dirks

Journal of Anatomy > 234 > 5 > 656 - 667

Starfish (order: Asteroidea) possess a complex endoskeleton composed of thousands of calcareous ossicles. These ossicles are embedded in a body wall mostly consisting of a complex collagen fiber array. The combination of soft and hard tissue provides a challenge for detailed morphological and histological studies. As a consequence, very little is known about the general biomechanics of echinoderm...

The Glendoe Tunnel Collapse in Scotland

S. R. Hencher

Rock Mechanics and Rock Engineering > 2019 > 52 > 10 > 4033-4055

For Glendoe hydro-electric scheme in Scotland, the tunnelling contract was design–build. After a year, the tunnel collapsed, blocking a 71-m length, which necessitated construction of a by-pass tunnel. The responsibility for the collapse was examined in court and the findings were later appealed by a further three judges. The judge of the first case found that the cause of the failure was “erodible...
