Children with cerebral palsy have larger Achilles tendon moment arms than typically developing children.

J Biomech 2018 Nov 16. Epub 2018 Nov 16.

School of Human Sciences, University of Western Australia, Perth, Australia. Electronic address:

The effectiveness of the plantarflexor muscle group to generate desired plantarflexion moments is modulated by the geometry of the Achilles tendon moment arm (ATMA). Children with cerebral palsy (CP) frequently have reduced plantarflexion function, which is commonly attributed to impaired muscle structure and function, however little attention has been paid to the potential contribution of ATMA geometry. The use of musculoskeletal modelling for the simulation of gait and understanding of gait mechanics, rely on accuracy of ATMA estimates. Read More

Cancer Res 2018 Nov 29. Epub 2018 Nov 29.

Department of Pharmacology, University of Michigan Medical School, Ann Arbor, Michigan.

Glioblastoma (GBM) is a highly aggressive form of cancer that is resistant to standard therapy with concurrent radiation and temozolomide, two agents that work by inducing DNA damage. An underlying cause of this resistance may be a subpopulation of cancer stem-like cells that display a heightened DNA damage response (DDR). Although this DDR represents an attractive therapeutic target for overcoming the resistance of GBMs to radiotherapy, until now, the cause of this DDR upregulation has not been understood. Read More

Evaluation of normal cadaveric Achilles tendon and enthesis with ultrashort echo time (UTE) magnetic resonance imaging and indentation testing.

NMR Biomed 2018 Nov 20:e4034. Epub 2018 Nov 20.

Department of Radiology, University of California, San Diego, CA, USA.

Entheses are regions where tendons and ligaments attach to bone, and are the primary target in seronegative and other diseases of the musculoskeletal (MSK) system. MRI has been widely used for visualizing features of inflammatory and degenerative MSK disease; however, normal tendons and entheses have short transverse relaxation times (T ), and show little or no signal with conventional clinical MRI pulse sequences, making it difficult to investigate their MR properties. In this study we examined the normal MR morphology of the cadaveric Achilles tendon and enthesis at 3 T using novel three-dimensional ultrashort echo time (3D UTE) Cones sequences, and at 11.

Division of Rheumatology, University of California David Geffen School of Medicine, Los Angeles, USA.

Alkaptonuria (AKU) is a rare autosomal recessive disorder that results from the deficient activity of homogentisate 1,2-dioxygenase and leads to increased levels of homogentisic acid (HGA) and its oxidized product benzoquinone acetic acid (BQA). Both HGA and BQA form polymerized deposits that lead to a bluish-black discoloration of the cartilage as well as degeneration, inflammation, and calcification of the tendons, ligaments, intervertebral discs, and large joints and increased bone resorption. A brittle and fragmented cartilage forms and leads to aberrant loading of the subchondral bone. Read More

Cellular senescence is a typical tumor-suppressive mechanism that restricts the proliferation of premalignant cells. However, mounting evidence suggests that senescent cells, which also persist in vivo, can promote the incidence of aging-related disorders principally via the senescence-associated secretory phenotype (SASP), among which cancer is particularly devastating. Despite the beneficial effects of the SASP on certain physiological events such as wound healing and tissue repair, more studies have demonstrated that senescent cells can substantially contribute to pathological conditions and accelerate disease exacerbation, particularly cancer resistance, relapse and metastasis.

Results of Achilles Tendon Excision for Purpose of Wound Closure: Case Series.

J Foot Ankle Surg 2018 Nov 15. Epub 2018 Nov 15.

Department of Orthopaedic Surgery, Tan Tock Seng Hospital, Singapore. Electronic address:

The loss of Achilles tendon results in reduced plantar flexion strength; however, in patients who are not fit for major reconstructive surgery, with soft-tissue defects overlying the tendon, Achilles tendon excision is a useful adjunct procedure for wound closure. We report 3 patients with infections around the Achilles tendons needing debridement procedures who underwent Achilles tendon excision for the purpose of wound closure. Local healing was achieved in all patients; all returned to their premorbid ambulatory status, and 2 could perform heel raise. Read More

Obesity-Related Foot Pain: Diagnosis and Surgical Planning.

Clin Podiatr Med Surg 2019 Jan 25;36(1):141-151. Epub 2018 Oct 25.

DeKalb Medical Center, 2701 North Decatur Road, Decatur, GA 30033, USA.

Obese patients are at higher risk for surgical complications and consist of a large portion of podiatric patients. Obese patients are additionally at increased risk of developing specific podiatric conditions, and it is important to be able to identify and appropriately treat these conditions accordingly. Initially, conservative treatment is adequate for a variety of pathologic conditions related to obesity. Read More

Making the SF5 Group More Accessible: A Gas Reagent-free Approach to Aryl Tetrafluoro-λ6-sulfanyl Chlorides.

Angew Chem Int Ed Engl 2018 Nov 14. Epub 2018 Nov 14.

ETH Zurich, Department of Chemistry, Vladimir-Prelog-Weg 2, CH-8093, Zurich, SWITZERLAND.

Modern pentafluorosulfanyl (SF5) chemistry has an Achilles heel: synthetic accessibility. Herein, we present the first approach to aryl-SF4Cl compounds (key intermediates in state-of-the-art aryl-SF5 synthesis) that overcomes the reliance on hazardous fluorinating reagents and/or gas reagents (e.g. Read More

Platelet rich plasma compared to dry needling in the treatment of non-insertional Achilles tendinopathy.

Phys Sportsmed 2018 Nov 14:1-6. Epub 2018 Nov 14.

a Department of Medicine and Science of Aging , University G. d'Annunzio , Chieti Scalo , Italy.

Objectives: The efficacy of platelet rich plasma in the treatment of Achilles tendinopathy is controversial. Despite positive results observed in open studies, randomized controlled trials failed to show difference against saline or rehabilitation. Aims of this retrospective observational study were to compare the efficacy of platelet-rich plasma and dry needling and to assess possible differences age and sex-related. Read More

Influence of altered geometry and material properties on tissue stress distribution under load in tendinopathic Achilles tendons - A subject-specific finite element analysis.

J Biomech 2018 Oct 28. Epub 2018 Oct 28.

Menzies Health Institute Queensland, Griffith University, Gold Coast Campus, Australia.

Achilles tendon material properties and geometry are altered in Achilles tendinopathy. The purpose of this study was to determine the relative contributions of altered material properties and geometry to free Achilles tendon stress distribution during a sub-maximal contraction in tendinopathic relative to healthy tendons. Tendinopathic (n = 8) and healthy tendons (n = 8) were imaged at rest and during a sub-maximal voluntary isometric contraction using three-dimensional freehand ultrasound. Read More
