Hong Yu, Huijuan Li, Qi Li
In molluscs, muscle contraction is triggered by a direct binding of Ca(2+) to myosin. The myosin essential light chain (MELC) provides the Ca(2+) binding site and is of importance for motor function and regulation. In this study, the complete cDNA sequence of MELC gene of the Pacific oyster, Crassostrea gigas, was obtained, and the expression profiles were performed in different tissues and different embryo-larval development stages. The results showed that the full length of C. gigas MELC (CgMELC) cDNA was 659 bp, containing a 5'-untranslated region of 73 bp, a 3'-untranslated region of 112 bp...

BACKGROUND: Inguinal hernia is a commonly encountered cause of pain in athletes. Because of the anatomic complexity, lack of standard imaging, and the dynamic condition, there is no unified opinion explaining its underlying pathology. HYPOTHESIS: Athletes with persistent groin pain would have a high prevalence of inguinal hernia with dynamic ultrasound, and herniorrhaphy would successfully return athletes to activity. STUDY DESIGN: Case-control study...

Purpose: Clinicians often test laryngeal sensation by touching the laryngeal mucosa with the tip of a flexible laryngoscope. However, the pressure applied to the larynx by using this touch method is unknown, and the expected responses elicited by this method are uncertain. The variability in pressure delivered by clinicians using the touch method was investigated, and the subject responses to the touches were also reported. Methods: A fiberoptic pressure sensor passed through the working channel of a laryngoscope, with its tip positioned at the distal port of the channel...

Myostatin (MSTN), also called growth and differentiation factor-8 (GDF-8), is a member of the transforming growth factor-β (TGF-β) superfamily and an inhibitor of muscle differentiation and growth. In this report, we identified and characterized a MSTN gene (CnMSTN) from the scallop Chlamys nobilis. The open reading frame of CnMSTN was 1374bp in length, encoding 457 amino acids. The structure of CnMSTN included a putative signal peptide, a TGF-β propeptide domain, and a conserved TGF-β domain. Phylogenetic analysis showed that the CnMSTN gene was clustered in the same subgroup with the MSTN gene found in Mollusca...

CONTEXT: Altered lower extremity muscle activity has been suggested to be associated with lower extremity kinematics in individuals with patellofemoral pain (PFP). However, few studies examined these relationships and the results are inconsistent. OBJECTIVES: To compare the lower extremity muscle activity, kinematics, pain level, and reach distance during the anterior reach of the Star Excursion Balance Test (SEBT) between participants with PFP and healthy individuals (CON)...

CONTEXT: Of the weight bearing exercises, single leg squat (SLS) represents one of the most commonly used hip strengthening exercises that require more gluteus medius (GMED) activity. To date, no studies have investigated how the four SLS exercises affects muscle imbalance of GMED, tensor fasciae latae (TFL), and adductor longus (AL), and kinematics of hip. OBJECTIVE: To investigate the hip muscle activities, onset time, and kinematics during four different SLS exercises (unilateral squat, unilateral wall-squat, lateral step-down, and front step-down) in subjects with GMED weakness...

BACKGROUND: Adductor canal block (ACB) and local infiltration anesthesia (LIA) are both widely accepted techniques for postoperative pain control without quadriceps weakness after total knee arthroplasty (TKA). However, the above techniques are insufficient in efficacy or duration. AIMS: The aim of our study was to address whether ACB plus posterior capsular infiltration (PCI) result in improved analgesia compared with ACB or LIA in patients underwent TKA during 48 h after operation...

Blue mussels (Mytilus edulis) are ecologically and economically important marine invertebrates whose populations are at risk from climate change-associated variation in their environment, such as decreased coastal salinity. Blue mussels are osmoconfomers and use components of the metabolome (free amino acids) to help maintain osmotic balance and cellular function during low salinity exposure. However, little is known about the capacity of blue mussels during the planktonic larval stages to regulate metabolites during osmotic stress...

Isolated focal dystonia is a debilitating movement disorder of unknown pathophysiology. Early studies in focal dystonias have pointed to segregated changes in brain activity and connectivity. Only recently, the notion that dystonia pathophysiology may lie in abnormalities of large-scale brain networks appeared in the literature. Here, we outline a novel concept of functional connectome-wide alterations that are linked to dystonia phenotype and genotype. Using a neural community detection strategy and graph theoretical analysis of functional fMRI data in human patients with the laryngeal form of dystonia (LD) and healthy controls (both males and females), we identified an abnormally widespread hub formation in dystonia, which particularly affected the primary sensorimotor and parietal cortices and thalamus...

BACKGROUND: Investigations in factor VII activating protease (FSAP)(-/-) mice suggest a role for FSAP in stroke, thrombosis and neointima formation. Here, we analyzed the role of FSAP in vascular remodeling processes related to arteriogenesis and angiogenesis in the mouse hind limb ischemia model. METHODS AND RESULTS: Femoral artery ligation was performed in mice and exogenous FSAP was injected locally to examine its effect on arteriogenesis in the adductor and angiogenesis in the gastrocnemius muscle over 21 days...

Yike Li, Gaelyn Garrett, David Zealear
Vocal fold paralysis (BVFP) refers to neurological causes of reduced or absent movement of one or both vocal folds. Bilateral BVFP is characterized by inspiratory dyspnea due to narrowing of the airway at the glottic level with both vocal folds assuming a paramedian position. The primary objective of intervention for BVFP is to relieve patients' dyspnea. Common clinical options for management include tracheostomy, arytenoidectomy and cordotomy. Other options that have been used with varying success include reinnervation techniques and botulinum toxin (Botox) injections into the vocal fold adductors...

The ulnar collateral ligament (UCL) of the thumb metacarpophalangeal joint is a static stabilizer that may rupture from a hyperabduction injury. Although some UCL tears may heal with immobilization, outcomes are worse for Stener lesions, in which the proximal ligament stump slips out from beneath the adductor pollicis aponeurosis and is entrapped proximal and superficial to the aponeurosis, preventing primary healing. We report the case of a patient with a Stener lesion with radiographic, ultrasound, and magnetic resonance imaging correlation, subsequently confirmed with intraoperative photographs...

Shengjun Wu, Yuping Wu
The proximate composition of pen shell adductor muscle (PSAM) was determined, and its nutrition value was evaluated. Proximate composition analysis indicated that PSAM contained 91.07% (w/w) protein, 5.77% (w/w) ash, and 2.46% (w/w) fat. Calcium was the predominant mineral followed by zinc and then iron. The amino acid profile was in accordance with the recommended pattern of FAO/WHO except for histidine. At the same time, the first limiting amino acid was histidine. Fatty acid composition showed that docosahexaenoic acid was the major fatty acid, followed by palmitic, stearic, and arachidonic acids...
