“…The viscosity coefficient of HA is not constant, and this fluid is not linearly viscous, but its viscosity is reduced under any loading condition, whilst the rest condition allows HA to return to a more viscous state [54]. Chytil et al [55] demonstrated that, at lower shear stress levels, chains of high molecular size HA (106-107 Da) are efficient in re-associating in their previous superstructure after the load has been removed. If the HA assumes more packed conformation, it increases the density of the loose connective tissue inside the fasciae, and consequently the behavior of the whole deep fascia could be compromised [16].…”

Fascial or Muscle Stretching? A Narrative Review

Stretching exercises are integral part of the rehabilitation and sport. Despite this, the mechanism behind its proposed effect remains ambiguous. It is assumed that flexibility increases, e.g., action on muscle and tendon, respectively, but this is not always present in the stretching protocol of the exercises used. Recently, the fasciae have increased popularity and seems that they can have a role to define the flexibility and the perception of the limitation of the maximal range of motion (ROM). Deep fascia is also considered a key element to transmit load in parallel bypassing the joints, transmitting around 30% of the force generated during a muscular contraction. So, it seems impossible dividing the action of the muscles from the fasciae, but they have to be considered as a “myofascial unit”. The purpose of this manuscript is to evaluate the mechanical behavior of muscles, tendons, and fasciae to better understand how they can interact during passive stretching. Stress-strain values of muscle, tendon and fascia demonstrate that during passive stretching, the fascia is the first tissue that limit the elongation, suggesting that fascial tissue is probably the major target of static stretching. A better understanding of myofascial force transmission, and the study of the biomechanical behavior of fasciae, with also the thixotropic effect, can help to design a correct plan of stretching.

“…In cosmetics, 'free-flowing starch' is starch granules that have been surface modified by OSA, followed by cross-linking with Al 3+ ions. One of the major advantages of this modification chemistry compared to others previously developed for modification of HA (Chytil, Strand, Christensen, & Pekar, 2010;Park, Chung, & Yoo, 2004;Tölg, Hamilton, & Turley, 2004), is that the by-products has been shown to be non-toxic and the modification chemicals and procedure is both easy and in-expensive requiring only one step (Heacock et al, 2004;Takihara et al, 2007;Trubiano, 1986).…”

“…Besides the lipid A, which is anchored directly in the biomembrane, the LPS also has an additional region consisting of a dozen sugar residues, known as the core region; the O-antigen polysaccharide linked to the core is specific for each type of bacterial strain, although some of the bacteria may have the same polysaccharide structure due to the horizontal transfer of the genetic information (Lawrence 1999), and is typically built of 10 -25 repeating units (RUs) having 2 -7 sugar residues per RU (Stenutz et al 2006). The structure and dynamics of polysaccharides are being studied by many different biophysical techniques (Carriere et al 1993;Tang et al 2004;Chytil et al 2010;Jasnin et al 2010) and NMR spectroscopy is an important one to this end (Hills et al 1991;Hricovini et al 1997;Vlachou et al 2001;Henderson et al 2003). Like for NMR investigations of proteins and nucleic acids the use of 13 C-and/or 15 N-isotope enrichment is a powerful approach to obtain high quality data for polysaccharides in solution (Gitti et al 1994;Kjellberg et al 1999;Norris et al 2012).…”
