PURPOSE To investigate the therapeutic effectiveness of ultrasound (US)-guided trigger point injection for myofascial trigger points (MTrPs) in the internal rotator muscles of the shoulder in post-mastectomy patients. MATERIALS AND METHODS This pilot study was a non-controlled, prospective, clinical trial. Nineteen post-mastectomy patients with a diagnosis of at least one active MTrP in the s...

BACKGROUND The purpose of this study was to determine whether patients with a poor prognosis for survival were more likely to undergo reconstruction with a pectoralis flap versus a free flap and whether the use of a pectoralis flap offered any perioperative advantage, such as a reduction in medical complications. METHODS Fifty-five consecutive patients who underwent immediate reconstruction a...

We investigated the effect of 2 months of exposure to cold conditions (0-5 C) on capillarization and on fiber size, distribution and ultrastructure in the pectoralis muscle of nine pigeons (Columbia livia; mean body mass 700 31 g) and compared the results with measurements from four control birds (mean mass 715 42 g) kept at normal ambient temperature (22-23 C) for the same period. Superficial ...

We developed an ELISA to measure heart-type fatty acid binding protein (H-FABP) in muscles of the western sandpiper (Calidris mauri), a long-distance migrant shorebird. H-FABP accounted for almost 11% of cytosolic protein in the heart. Pectoralis H-FABP levels were highest during migration (10%) and declined to 6% in tropically wintering female sandpipers. Premigratory birds increased body fat,...

An axillary arch is considered to be an variant muscle or tendinous slip that arises form the lower border of latissimus dorsi to join the tendon of pectoralis major, coracobrachalis, or fascia over the biceps. It is present in about 7% of the cases and may be multiple [1]. An axillary arch is thought to be a vestige of panniculus carnosus muscle [2]. Thoracoepicondylaris is a very rare muscula...

Comparative characteristics, common and distinctive features of qualitative and quantitative composition of myofibril proteins of skeletal muscles of some deep-sea fish species (Podonema longipes, Coryphaenoides cinereus, Coryphaenoides pectoralis) have been determined. Myofibrillar proteins were extracted from the skeletal muscle of three species deep-sea fish and their relative molecular mass...

Little is known about how in vivo muscle efficiency, that is the ratio of mechanical and metabolic power, is affected by changes in locomotory tasks. One of the main problems with determining in vivo muscle efficiency is the large number of muscles generally used to produce mechanical power. Animal flight provides a unique model for determining muscle efficiency because only one muscle, the pec...

The purpose of this study was to compare one-repetition maximum (1-RM) and muscle activity in three chest-press exercises with different stability requirements (Smith machine, barbell, and dumbbells). Twelve healthy, resistance-trained males (age 22.7 ± 1.7 years, body mass 78.6 ± 7.6 kg, stature 1.80 ± 0.06 m) were tested for 1-RM of the three chest-press exercises in counterbalanced order wit...

DESCRIPTION A 48-year-old woman, 34 weeks status post primary cosmetic bilateral breast augmentation, presented with right double-bubble deformity. The patient reported persistent right breast pain, particularly on contraction of the right pectoralis muscle.

Latar Belakang: Pembedahan kanker daerah kepala dan leher umumnya menimbulkan defek luas biasanya memerlukan flap. Meskipun free flap saat ini merupakan gold standard untuk rekonstruksi leher, pectoralis major myocutaneous (PMMC) masih digunakan. Kasus: Perempuan usia 47 tahun, dengan tiroid papiler T4aN0M0 ulserasi di kulit menjalani tiroidektomi total operasi direkonstruksi Hasil dapat diteri...
