Clinical and biological characterization of skeletal muscle tissue biopsies of surgical cancer patients.

Researchers increasingly use intraoperative muscle biopsy to investigate mechanisms of skeletal muscle atrophy in patients with cancer. Muscles have been assessed for morphological, cellular, and biochemical features. The aim of this study was to conduct a state-of-the-science review of this literature and, secondly, to evaluate clinical and biological variation in biopsies of rectus abdominis (RA) muscle from a cohort of patients with malignancies.

Original concepts in anatomy, abdominal-wall surgery, and component separation technique and strategy.

The abdominal wall can be considered comprised of two compartments: an anterior and a posterior compartment. The anterior compartment includes the anterior rectus sheath and the rectus muscle. The posterior compartment comprises the posterior rectus sheath, the transversalis fascia, and the peritoneum. When a large defect in the anterior compartment has to be corrected, for example, a rectus diastasis or large incisional hernia, an action on the anterior compartment is necessary; therefore, an anterior comp...

Correlation Between Optical Coherence Tomography and Magnetic Resonance Imaging of Rectus Muscle Thickness Measurements in Graves' Ophthalmopathy.

To assess the correlation between optical coherence tomography (OCT) and magnetic resonance imaging (MRI) measurements of extraocular rectus muscle thickness in patients with Graves' ophthalmopathy.

The Impact of Canalplasty on Outcomes of Medial Graft Tympanoplasty.

Both medial and lateral graft techniques are commonly employed in tympanoplasty with acceptable closure rates. Canalplasty is routinely performed to obtain adequate exposure in the lateral graft technique; this usually entails removal of the anterior canal wall skin with subsequent replacement as a free graft. While formal canalplasty can also be performed in conjunction with medial graft technique to improve exposure, it is not commonly described. The current study seeks to examine the impact of canalplast...

Single motor units from the medial pterygoid muscle can be active during isometric horizontal and vertical forces.

To determine (a) whether the medial pterygoid muscle is active in an isometric vertical force task and in isometric horizontal force tasks in the contralateral, protrusion and ipsilateral directions, (b) whether the same single motor units (SMUs) could be active across different directions of isometric force generation, and (c) whether different regions of the medial pterygoid muscle exhibit different patterns of SMU activation during the generation of any one direction of isometric force.

Neurons and networks in the entorhinal cortex: A reappraisal of the lateral and medial entorhinal subdivisions mediating parallel cortical pathways.

In this review, we aim to reappraise the organization of intrinsic and extrinsic networks of the entorhinal cortex with a focus on the concept of parallel cortical connectivity streams. The concept of two entorhinal areas, the lateral and medial entorhinal cortex, belonging to two parallel input-output streams mediating the encoding and storage of respectively what and where information hinges on the claim that a major component of their cortical connections is with the perirhinal cortex and postrhinal or p...

The subjects were divided into two groups based on the SS duration as follows: 2 min (n=10) and 5 min (n=10). At rest and after 2 and 5 min of SS, stiffness and blood flow va...

Bilateral differences in the trunk muscle volume of skilled golfers.

Repetitive mechanical load applied to a body part may lead to hypertrophy of its muscles. If a movement requires asymmetric activation of bilateral muscles, this may result in differences in muscle size between the sides. This study aimed to investigate the degree of bilateral differences in the trunk muscle volume of golfers by comparing with non-golfers. Seventeen male right-handed golfers and eleven (nine right- and two left-handed) non-golfers participated. Trunk muscle volume was determined using magne...

A Comparison of Split Peroneus Brevis Tendon and Semitendinosus Allograft Tendon for Lateral Ankle Ligament Reconstruction.

Lateral ankle instability is a debilitating condition that is often unresponsive to conservative therapy. Many techniques for operative repair have been proposed, most commonly performed as the Broström or modified Broström procedure. In patients with failed primary repair, hereditary collagen disorders, strenuous work activity, obesity, or ligamentous laxity, the Broström repair is less likely to be successful, and anatomic or nonanatomic reconstruction should be considered. The purpose of this study wa...

Cetacean Orbital Muscles: Anatomy and Function of the Circular Layers.

Dissections of cetacean orbits identified two distinct circular muscle layers that are uniquely more elaborate than the orbitalis muscles described in numerous mammals. The circular orbital muscles in cetaceans form layers that lie both external and internal to the rectus extra ocular muscles (EOMs). A cone-shaped external circular muscle (ECM) that invests the external surface of the rectus EOMs was found in all cetacean specimens examined. The cetacean ECM corresponds generally to descriptions of the musc...

The influence of femoral and tibial bony anatomy on valgus OA of the knee.

Approximately 10% of all patients that require a total knee arthroplasty present with valgus osteoarthritis (OA) of the knee. Valgus OA goes along with posterolateral bone loss and lateral soft tissue tightness. The role of malalignment on the development of OA is not fully understood. The current study investigates whether the femoral offset (FO), femoral mechanical-anatomical (FMA) angle, anatomical lateral distal femur angle (aLDFA), mechanical lateral distal femur angle (mLDFA), medial proximal femur an...

Effect of aging on the association between ankle muscle strength and the control of bipedal stance.

Previous studies reported a significant association between postural control and lower-limb strength of several muscle groups, however, they were focused especially on knee muscles and ankle plantar and dorsal flexors. The aim of the present study is to examine the correlation between the muscle strength of ankle invertors, evertors, plantar flexors, and dorsal flexors and the control of bipedal stance in young and older adults. Thirty one young (aged 22.8 ± 2.6 years) and thirty one older adults (aged 70....
