An injectable adhesive hydrogel composed of carboxymethyl cellulose (CMC) and pullulan is developed and evaluated as a postoperative anti-adhesion barrier. CMC was modified with tyramine to introduce crosslinking via an EDC-NHS reaction. The in situ hydrogel was developed by an enzyme-mediated reaction of tyramine-immobilized CMC with horseradish peroxidase (HRP) and hydrogen peroxide (H2O2). Pullulan was added to the hydrogel solution to improve adhesiveness to the wound area and accelerate biodegradation...

Antagonist muscle co-activation is thought to be partially regulated by cortical influences, but direct motor cortex involvement is not fully understood. Corticomuscular coherence (CMC) measures direct functional coupling of the motor cortex and muscles. As antagonist co-activation differs according to training status, comparison of CMC in agonist and antagonist muscles and in strength-trained and endurance-trained individuals may provide in-depth knowledge of cortical implication in antagonist muscle co-activation...

BACKGROUND: Therapy programs to treat thumb carpometacarpal (CMC) arthritis may engage selective activation and reeducation of thenar muscles, particularly the first dorsal interosseous (FDI) and opponens pollicis (OP) to reduce subluxation of the joint. We describe the effect of simulated selective activation of the FDI and OP muscles upon radiographic subluxation of the thumb CMC joint. METHODS: In a cadaver model of CMC subluxation, loads were applied to the FDI, the OP, and then concomitantly at 0%, 25%, 50%, 75%, and 100% maximal loads and radial subluxation of the joint and reduction in subluxation was measured...

Carpometacarpal (CMC) fracture-dislocations of the fifth ray are common. For chronic injuries, Dubert proposed combining resection arthroplasty of the base of the fifth metacarpal (M5) with synostosis with the fourth metacarpal (M4). Our aim was to evaluate the results of this procedure. Between 1994 and 2014, 7 men and 1 woman with an average age of 36 years (range, 27 to 45) were operated on. The right hand was involved in 6 of the 8 cases. All patients had symptomatic osteoarthritis secondary to isolated articular malunion and subluxation of the 5th CMC joint...

A novel axially chiral cationic Gemini amphiphile gelator (S1) derived from (S)-BINOL has been synthesized and characterized by (1)H NMR, (13)C NMR, ESI-MS and FT-IR analyses. The critical micelle concentration (CMC) of S1 was determined to be 0.21 mM in water at room temperature. A transparent hydrogel with S1 at 43 mM was obtained at room temperature and characterized using various methods including SEM, CD, fluorescence, (1)H NMR, FT-IR, and XRD. The results indicate that the hydrophobic effect of long alkyl chains, π-π stacking of naphthalene rings, and intermolecular hydrogen-bonding of the amide groups of S1 should be responsible for the hydrogel formation...

The aim of this study was to perform multi-body, muscle-driven, forward-dynamics simulations of human gait using a 6-degree-of-freedom (6-DOF) model of the knee in tandem with a surrogate model of articular contact and force control. A forward-dynamics simulation incorporating position, velocity and contact force-feedback control (FFC) was used to track full-body motion capture data recorded for multiple trials of level walking and stair descent performed by two individuals with instrumented knee implants. Tibiofemoral contact force errors for FFC were compared against those obtained from a standard computed muscle control algorithm (CMC) with a 6-DOF knee contact model (CMC6); CMC with a 1-DOF translating hinge-knee model (CMC1); and static optimization with a 1-DOF translating hinge-knee model (SO)...

Polycystic ovarian syndrome (PCOS) is associated with multiple cardiovascular risk factors (CVRF) including endothelial dysfunction (ED) and presence of metabolic syndrome (MS). The probable reason suggested for elevated CVRF in PCOS is oxidative stress (OS), which is an integral factor in cardiometabolic complications (CMC) seen in PCOS women. The interrelated mechanisms by which CVRF instigate clinical manifestation plays a crucial role in identification of a strategy to treat different comorbidities in PCOS...

Protein complex detection in PPI networks plays an important role in analyzing biological processes. A new algorithm-DBGPWN-is proposed for predicting complexes in PPI networks. Firstly, a method based on gene ontology is used to measure semantic similarities between interacted proteins, and the similarity values are used as their weights. Then, a density-based graph partitioning algorithm is developed to find clusters in the weighted PPI networks, and the identified ones are considered to be dense and similar...

Soy molasses is a product co-generated during soybean processing that has high production and low commercial value. Its use has great potential in fermentative processes due to the high concentration of carbohydrates, lipids and proteins. This study investigated the use of Pseudomonas aeruginosa to produce biosurfactants in a soy molasses-based fermentation medium. A central composite design (CCD) was prepared with two variables and three replicates at the central point to optimize the production of biosurfactant...

Cortical involvement in essential tremor, an involuntary action tremor supposedly of subcortical origin, is uncertain. Conflicting results of corticomuscular coherence studies in essential tremor might suggest intermittent corticomuscular coupling. Based on the literature, we hypothesize that corticomuscular coupling is influenced by bilateral motor synchronization and 'cognitive states' such as awareness of tremor. Here, we investigated 1) the existence of intermittent CMC in essential tremor, and 2) factors that influence CMC strength...

After spinal cord injury (SCI), the reorganization of the neuromuscular system leads to increased antagonist muscles' co-activation - i.e., increased antagonist vs. agonist muscles activation ratio - during voluntary contractions. Increased muscle co-activation is supposed to result from reduced cortical influences on spinal mechanisms inhibiting antagonist muscles. The assessment of the residual interactions between cortical and muscles activity with corticomuscular coherence (CMC) in participants with SCI producing different force levels may shed new lights on the regulation of muscle co-activation...

Tocopheryl polyethylene glycol 1000 succinate (TPGS) is considered a promising surfactant, but its high critical micelle concentration (CMC) limits its application. Cholesterol is hydrophobic, can act as a tumor-targeting ligand, and has strong binding ability with taxoids. Based on this information, we coupled cholesterol with TPGS to synthesize cholesterol-coupled TPGS (TPGS-CHMC), which had a lower CMC than pure TPGS. The TPGS-CHMC was used to prepare micelles loading with docetaxel (DTX) by a self-assembly method...

Development of healthier meat products is needed to meet consumers' request. The effects of dietary fiber addition on the water distribution, water binding capacity (WBC), and textural properties of a fat-reduced model meat system enriched with inulin, cellulose, carboxymethyl cellulose (CMC), chitosan, pectin, respectively, were investigated in this study. The fibers were incorporated in powder form to constitute 2% (w/w) of the meat batter. In general, fiber enrichment resulted in significant lower cooking loss and improved WBC, while the impact on texture was dependent on the specific dietary fiber...
