BACKGROUND A pectoralis major flap is one of the standard tools for the reconstruction of defects of the head and neck. Despite the technical advancement in free tissue transfer in head and neck reconstruction, the benefits of a pectoralis major flap should not be overlooked. The purpose of this study is to evaluate our 17 years of experience in reconstructing defects of the head and neck regio...

Flexible metabolic phenotypes allow animals to adjust physiology to better fit ecological or environmental demands, thereby influencing fitness. Summit metabolic rate (Msum = maximal thermogenic capacity) is one such flexible trait. Skeletal muscle and heart masses and myocyte metabolic intensity are potential drivers of Msum flexibility in birds. We examined correlations of skeletal muscle and...

Scincid lizards belonging to the genus Carlia are found in eastern and northern Australia and in New Guinea and associated islands. These skinks are a particularly diverse component of the reptile fauna of north-east Australia. Carlia pectoralis (de Vis 1884) was formerly regarded as occurring over much of eastern Queensland, in north-east Australia. Here we show that it consists of four specie...

A novel method for the control of a myoelectric upper limb prosthesis was achieved in a patient with bilateral amputations at the shoulder disarticulation level. Four independently controlled nerve-muscle units were created by surgically anastomosing residual brachial plexus nerves to dissected and divided aspects of the pectoralis major and minor muscles. The musculocutaneous nerve was anastom...

OBJECTIVE This study aims to report the use of the unilateral pectoralis major muscle flap for the treatment of the sternal wound dehiscence. METHODS A retrospective study including patients who underwent unilateral pectoralis major muscle flap was performed for the treatment of sternotomy dehiscence due to coronary artery bypass, valve replacement, congenital heart disease correction and med...

In the final stage of fasting, skeletal muscle mass and protein content drastically decrease when the maintenance of efficient locomotor activity becomes crucial for animals to reactivate feeding behaviour and survive a very long period of starvation. As mitochondrial metabolism represents the main physiological link between the endogenous energy store and animal performance, the aim of this st...

ABSTRACT Pectoralis major rupture is a relatively uncommon injury. It is often under- or misdiagnosed due to late presentation and the lack of obvious clinical signs. Timely diagnosis and treatment is crucial, as early surgical repair has been shown to improve functional and cosmetic outcomes. We report the case of a young patient who underwent surgical repair of a right pectoralis major ruptur...

Two patients presented with pain in the arm and a radiographic lesion of the upper humerus which warranted surgical exploration and excision biopsy. In both cases the pathology was inflammatory and involved the insertion of pectoralis major. Tendinitis of the pectoralis major with an associated lesion of the humerus has not previously been described.

Rupture of the pectoralis major muscle is relatively rare. The authors present two cases of chronic rupture in which direct suturing was not possible; reconstruction was possible using a bone-patellar tendon autograft. They conclude that this surgical technique may be useful in some cases of chronic ruptures of the pectoralis major muscle in which direct tendon suturing is impossible.

Branchioblastoma in Sardinella longiceps is described in present study. Large tumour masses were found under the operculum. Tumour is characterized by the multilobed and pale to red in color and located in the brachial chamber of the fish. It varied in consistency from very soft and triable to hard and also vary in size from 17 mm to 33 mm in diameter and 18 to 44 mm in length. Prevalence study...
