[Purpose] The purpose of the present study was to determine the effects of changes in palmar width on the muscle activities of the shoulder and truncus muscles during push-up exercise. [Subjects] Twelve healthy adult males participated in this study as subjects. [Methods] Push-up exercises were performed with three different palmar width in narrow (50%), neutral (100%), and wide positions (150%...

We have studied the structure of myosin heavy chain (MHC) in the pectoralis muscle of genetically dystrophic (Connecticut Strain) and White Leghorn chicks. MHC was alkylated with N-ethylmaleimide, purified by Sepharose-4B chromatography, and cleaved with cyanogen bromide. The MHC CNBr peptides were analyzed by one-dimensional and two-dimensional isoelectric focusing/sodium dodecyl sulfate gradi...

seen following repeated or prolonged hyperabduction of the arms. The sites of compression are thought to be the point at which these neurovascular structures emerge from beneath the pectoralis minor tendon and the interval between the clavicle and the first rib. Five patients presenting the hyperabduction syndrome have been subjected to pectoralis minor tenotomy and anterior scalenotomy with a ...

disinsertion of the pectoralis major muscle. This technique can produce significant postoperative pain and lead to breast animation deformities. Prepectoral breast reconstruction is an alternative technique that involves expander/implant placement in the prepectoral space with complete acellular dermal matrix coverage, thus eliminating the need for pectoralis muscle disruption. In this study, w...

BACKGROUND Pectoralis minor adaptive shortening may change scapula resting position and scapular kinematics during arm elevation. A reliable and clinically feasible method for measuring pectoralis minor length will be useful for clinical decision making when evaluating and treating individuals with shoulder pain and dysfunction. OBJECTIVES To evaluate intrarater, interrater, and between-day r...

Thoracic outlet syndrome is the result of compression or irritation of neurovascular bundles as they pass from the lower cervical spine into the arm, via the axilla. If the pectoralis minor muscle is involved the patient may present with chest pain, along with pain and paraesthesia into the arm. These symptoms are also commonly seen in patients with chest pain of a cardiac origin. In this case,...

Maximal metabolic outputs for exercise and thermogenesis in birds presumably influence fitness through effects on flight and shivering performance. Because both summit (Msum, maximum thermoregulatory metabolic rate) and maximum (MMR, maximum exercise metabolic rate) metabolic rates are functions of skeletal muscle activity, correlations between these measurements and their mechanistic underpinn...

With the steady technological development enabling reduced device dimensions and new patient populations, detailed data on mechanical in vivo loads become increasingly important to ensure reliability of implantable medical devices. Based on an intra-species correlation of in-line and transverse force of the Pectoralis major established previously for the Chacma baboon (de Vaal et al., 2010a), a...

a survey on endo-parasitic infections on barboid fishes of south- west of iran (khouzestan province) was carried out from spring 2007 to atumn 2009. altogether 296 specimens from five different fish species were examined, they are barbus grypus heckel, 1843; barbus sharpeyi günther, 1874; barbus esocinus heckel, 1843; barbus barbulus heckel, 1849 and barbus pectoralis heckel 1843. the fishes we...
