Experiments were carried out to investigate the bioaccumulation and elimination of cadmium (Cd) in tissues (kidney, gills, digestive gland, mantle, visceral mass, foot, adductor muscle and hemolymph) from the freshwater mussel, Anodonta woodiana. The mussels were exposed to subchronic Cd at concentrations of 0.168 and 0.675 mg L-1 for 28 d of bioaccumulation and 28 d of elimination. During the bioaccumulation phase, Cd bioaccumulations increased in all tissues. The highest bioaccumulation of Cd was found in the kidney...

OBJECTIVES/HYPOTHESIS: The aim of this study was to analyze the phoniatric and respiratory outcomes of a subset of bilateral vocal cord paralysis (BVCP) patients who were all treated with unilateral endoscopic arytenoid abduction lateropexy (EAAL). EAAL is a nondestructive, minimally invasive glottis widening operation, which does not damage either the surgically treated or the contralateral vocal cord. Therefore, it does not impair the regeneration potential of the recurrent laryngeal nerve...

BACKGROUND AND OBJECTIVE: Oculopharyngeal muscular dystrophy (OPMD) is a genetic disorder caused by an abnormal expansion of GCN triplets within the PABPN1 gene. Previous descriptions have focused on lower limb muscles in small cohorts of patients with OPMD, but larger imaging studies have not been performed. Previous imaging studies have been too small to be able to correlate imaging findings to genetic and clinical data. METHODS: We present cross-sectional, T1-weighted muscle MRI and CT-scan data from 168 patients with genetically confirmed OPMD...

BACKGROUND: Femoroacetabular impingement (FAI) syndrome is a hip joint motion-related clinical disorder characterized by abnormal contact between the hip joint structures. Abnormal hip morphology and joint pain may impair the hip joint range of motion (ROM) and muscle function. However, FAI effects on hip joint ROM and muscle strength remain controversial. OBJECTIVES: The purpose of this study was to compare hip joint ROM and muscle strength between FAI syndrome patients and healthy controls...

STUDY DESIGN: Single-blind, randomized controlled trial. BACKGROUND: Treatments for rotator cuff (RC) tendinopathy include RC muscle strengthening to promote better muscle recruitment in order to minimize subacromial narrowing during active movement. Glenohumeral adductors recruitment has also been shown to prevent such narrowing in asymptomatic individuals; therefore, adding glenohumeral adductor coactivation during RC strengthening could enhance the efficacy of RC strengthening...

The development of bivalves has been extensively studied over the last 150 years. Despite this, the developmental dynamics of myogenesis in bivalves remains largely unknown, particularly at the early developmental stages. In the present study, we investigate the characteristics of muscle development of Yesso scallop Patinopecten yessoensis by phalloidin staining, light, electron and confocal microscopy. Myoblasts containing chaotic myofilaments are initially found in the blastocoel of trochophore, and become more organized during the transformation from trochophore into veliger...

The study aimed to evaluate the chemical composition and nutraceutical potential of two commercially significant edible bivalve mollusc species ( Anadara broughtonii and Mactra chinensis ). The edible parts (motor muscle, mantle and adductor) of these molluscs were analyzed for their proximate composition, collagen content, amino acid profile, chemical score and elemental constituents. Both molluscs had low fat content (2.43-6.91 g/100 g dry weight), and protein (55.36-68.01 g/100 g dry weight) and carbohydrates (11...

Soccer is the most popular sport in the world and has the fourth highest number of sports injuries. Hip and groin injuries account for 14% of soccer injuries and can be difficult to recognize and treat as they often require a high level of suspicion and advanced imaging. Groin pain can be separated into 3 categories: (1) defined clinical entities for groin pain (adductor-related, iliopsoas-related, inguinal-related [sports hernias/athletic pubalgia], and pubic-related groin pain), (2) hip-related groin pain (hip morphologic abnormalities, labral tears, and chondral injuries), and (3) other causes of groin pain...

A 14-year-old female ballet dancer sustained an injury during a routine ballet movement that was diagnosed as an ischial tuberosity avulsion fracture. This diagnosis was complicated by extensive soft tissue injury to the hamstrings, adductors, and external rotator musculature. Although uncommon, the potential for this injury should be uniformly considered in adolescent dancers due to the unique stresses in ballet training and the added risk of growth spurts during this stage of development. Prevention targeting individual deficiencies in flexibility and strength is essential to avoid similar devastating injuries...

INTRODUCTION: Ischial tuberosity fractures and complications may be an under recognized diagnosis in adolescent athletes. Operative interventions differ and may include anchor re-fixations, resections and osteostimulating drilling and partial hamstring releases. This case report illustrates a novel and less invasive management of a non-union following a proximal ischial tuberosity avulsion. This approach has to our knowledge not previously been described. PRESENTATION OF CASE: The patient, a 14 years old female athlete, was complaining of sharp pain in the right side of the groin region, after an acute injury during a handball game...

Recently, we reported an emerging pathology named Brown Muscle Disease (BMD) affecting Asari clams inhabiting the most productive area for this species in France, the Arcachon Bay. The main macroscopic feature of the pathology relies on the atrophy of the posterior adductor muscle, affecting the ability of clams to burry. The research of the etiological agent of BMD privileged a viral infection. Contrary to healthy clams, infected animals are always found at the surface of the sediment and exhibit 30 nm virus-like particles in muscle, granulocytic and rectal cells...

Aging brings about challenges in the ability to recover balance through protective stepping, especially in the lateral direction. Previous work has suggested that lateral protective stepping during weight transfer may be affected by impaired muscle composition and performance of the hip abductors (AB) in older adults. Hence, this study investigated the influence of hip abductor-adductor (AB-AD) neuromuscular performance on the weight transfer phase of lateral protective stepping in younger and older adults...
