Joint centration

F Plachel, S Pauly, P Moroder, M Scheibel
OBJECTIVE: Reconstruction of tendon integrity to maintain glenohumeral joint centration and hence to restore shoulder functional range of motion and to reduce pain. INDICATIONS: Isolated or combined full-thickness subscapularis tendon tears (≥upper two-thirds of the tendon) without both substantial soft tissue degeneration and cranialization of the humeral head. CONTRAINDICATIONS: Chronic tears of the subscapularis tendon with higher grade muscle atrophy, fatty infiltration, and static decentration of the humeral head...

OBJECTIVE: To identify the possibility of modification by astaxanthin the level of genome damages induced by gamma quanta in the culture of human peripheral blood lymphocytes exposed in vitro on postsynthetic (G2) phase of the first mitotic cycle. MATERIALS AND METHODS: Peripheral blood lymphocytes from four apparently healthy volunteers 35-51 years old were cultivated using modified micromethod. To obtain genomic damages in G2 phase of the first mitotic cycle the part of cultures was irradiated by γ quanta in dose 1...

The focus of modelling in wastewater treatment is shifting from single unit to plant-wide scale. Plant-wide modelling approaches provide opportunities to study the dynamics and interactions of different transformations in water and sludge streams. Towards developing more general and robust simulation tools applicable to a broad range of wastewater engineering problems, this paper evaluates a plant-wide model built with sub-models from the Benchmark Simulation Model No. 2-P (BSM2-P) with an improved/expanded physico-chemical framework (PCF)...

BACKGROUND: The structure of apophyses and apophyseal growth plates is not substantially different from those of epiphyses and epiphyseal growth plates. In contrast to epiphyseal growth plates, apophyses and apophyseal growth plates do not contribute to the longitudinal growth of the extremity. They are associated with their adjacent joints, triggering the lengths of their lever arms and influencing their external shape and internal architecture. The formative stimulus on apophyses is given by muscles and tendons inserting at the apophysis or canopying the apophsis...

This study examined pulling exercises performed on stable surfaces and unstable suspension straps. Specific questions included: which exercises challenged particular muscles, what was the magnitude of resulting spine load, and did technique coaching influence results. Fourteen males performed pulling tasks while muscle activity, external force, and 3D body segment motion were recorded. These data were processed and input to a sophisticated and anatomically detailed 3D model that used muscle activity and body segment kinematics to estimate muscle force, in this way the model was sensitive to each individual's choice of motor control for each task...

The effects of water-retaining agent (60 kg x hm(-2)) and nitrogen fertilizer (0, 225, and 450 kg x hm(-2)) on the leaf photosynthetic characteristics, chlorophyll content, and water utilization of winter wheat at jointing and grain-filling stages were studied under field conditions. In all treatments, the net photosynthetic rate, stomata conductance, intercellular CO2 concentration, water use efficiency, and chlorophyll content were greater at grain-filling stage than at jointing stage. Under nitrogen fertilization but without water-retaining agent application, the water use efficiency (WUE) of single leaf at jointing stage increased with increasing nitrogen fertilization rate, while the net photosynthetic rate, stomata conductance, intercellular CO2 concentration, and transpiration rate decreased after an initial increase...

This study aimed to investigate if old men were more susceptible than young men to muscle damage induced by exercise consisting of repeated-lengthening muscle actions. The responses to a bout of eccentric exercise were compared between 10 young (mean age +/- SEM = 19.4 +/- 0.4 y) and 10 old (70.5 +/- 1.5 y) men. All subjects performed 6 sets of 5 lengthening actions of the left elbow flexors at a range of 90 degrees from an elbow flexed (90 degrees ) to an extended (180 degrees ) position in 5 s using a dumbbell massed at 40% maximal isometric strength (MVC) at an elbow joint angle of 90 degrees ...

The Ammonia Recovery Process (ARP) is an award-winning, low-cost, environmentally responsible method of recovering nitrogen, in the form of ammonia, from various dilute waste streams and converting it into concentrated ammonium sulfate. The ThermoEnergy Biogas System utilizes the new chemisorption-based ARP to recover ammonia from anaerobically digested wastes. The process provides for optimal biogas production and significantly reduced nitrogen levels in the treated water discharge. Process flows for the ammonia recovery and ThermoEnergy biogas processes are presented and discussed...

We have previously reported that a combination of transforming growth factor (TGF)-beta1 and basic fibroblast growth factor (bFGF) synergistically increases the proliferation of chondrocytes obtained from knee joint immobilized for 7-14 days in male Japanese white rabbits. In the present study, we performed experiments with chondrocytes and syn ovial fluid obtained from rabbit knees immobilized for 0-42 days, to clarify the sequential changes in TGF-beta1 and bFGF concentrations in synovial fluid and the mRNA expression of TGF-beta1 receptor type I (RI) and II (RII) in chondrocytes after immobilization...

An intertrochanteric femoral osteotomy is carried out to correct intoeing gait and to improve hip centration in patients with spastic cerebral palsy. The long-term effect of such osteotomies on the neck-shaft angle (NSA) and anteversion angle (ATA), as well as on hip-joint centration, was evaluated in 63 hips of 45 patients with observation times of 11-18 years (mean, 15.4). The postoperative loss of correction of the NSA and ATA was the more pronounced the younger the patients were at the time of intervention...
