Isometric shoulder strength: Normative Australian population data and associated factors.

Background: Age and sex are known predictors of isometric shoulder strength and therefore must be accounted for when noting strength values or administering assessments such as the Constant Score. Given the popularity of the Constant Score, it is important to ensure protocols and values remain clinically relevant and are representative of the intended population.

Method: Isometric shoulder strength was recorded for 511 participants without shoulder pathology using the Chatillon hand-held dynamometer.

Molecular basis of hyper-thermostability in the thermophilic archaeal aldolase MfnB.

Methanogenic archaea are chemolithotrophic prokaryotes that can reduce carbon dioxide with hydrogen gas to form methane. These microorganisms make a significant contribution to the global carbon cycle, with methanogenic archaea from anoxic environments estimated to contribute > 500 million tons of global methane annually. Archaeal methanogenesis is dependent on the methanofurans; aminomethylfuran containing coenzymes that act as the primary C acceptor molecule during carbon dioxide fixation.

Genetic Variants in the Gene Are Associated with Ramon Syndrome and Hereditary Gingival Fibromatosis.

Ramon syndrome (MIM 266270) is an extremely rare genetic syndrome, characterized by gingival fibromatosis, cherubism-like lesions, epilepsy, intellectual disability, hypertrichosis, short stature, juvenile rheumatoid arthritis, and ocular abnormalities. Hereditary or non-syndromic gingival fibromatosis (HGF) is also rare and considered to represent a heterogeneous group of disorders characterized by benign, slowly progressive, non-inflammatory gingival overgrowth. To date, two genes, and , have been linked to Ramon syndrome.

Scapulothoracic tenodesis using hamstring tendon graft for treatment of problematic scapula winging: A new surgical technique.

Introduction: Winging of the scapula occurs due to dysfunction of its stabilising muscles, most commonly serratus anterior and/or trapezius, for example in facioscapulohumeral muscular dystrophy. Resultant loss of scapular control and abnormal kinematics can decrease shoulder function due to glenohumeral joint instability, loss of range of motion and pain. Previously described treatment for cases resistant to physiotherapy includes scapulothoracic arthrodesis which involves risk of non-union and metalwork failure, as well as reduced respiratory function due to immobilisation of a segment of the adjacent chest wall.
