Vocal Fold Fat injection for Glottic Insufficiency: Systematic Review.

Unlabelled: Vocal fold fat injection is a technique for treating glottic insufficiency (GI) resulting from various conditions. The use of fat as a graft has several advantages over other grafts. Similar pliability, and vibratory characteristics as a normal vocal fold, not causing foreign body reactions, having the potential to contain stem cells, and often can be done in the office.

[Proliferative activity of paravasal connective tissue cells in the age aspect.].

The aim of the study was to investigate the age-related variability of the proliferative activity of fibroblasts of the paravasal connective tissue of the hollow and parenchymal organs of men corpses of the first period of mature age, elderly and senile age by detecting the expression of the Ki-67 protein (MIB-1 clone) and calculating the proliferation index. The results showed that in the first period of mature age, the proliferation index is almost at the same level in the paravasal tissue cells of the parenchymal and hollow organs of the digestive tract, while the fibroblasts of the paravasal tissue of the heart have the lowest proliferation activity among all the organs studied. With age, the intensity of cell proliferation decreases, moreover, at the age of more than 75 years, a distinct organ specificity is revealed.

[Age changes in connective tissue structures of the stomach.].

The study of paravasal connective tissue of the stomach was carried out on the preparations of 80 men corpses of three age groups: the first period of adulthood (n=20), the elderly (n=30) and senile (n=30) ages. With the help of standard histological and histochemical methods, the features of the age-related variability of the fiber composition were established; the level of apoptosis and proliferation in fibroblasts has been investigated with the help of immunohistochemical methods. The regularities of the structural organization of the paravasal connective tissue of the stomach during the period of biological stability (the first period of adulthood), as well as its age transformations at the stages of postnatal ontogeny (in the older age groups), were revealed.

[Age-related changes Kernogan`s index of venous vessels hollow and parenchymatous organs at stages of a postnatal ontogenesis].

Kernogan`s index determination of hollow and parenchymatous organs' venous vessels was conducted on 80 men corpses of the three age groups. Average age of the investigated men corpses of the mature period is 27,8±4,2 years, elderly - 67,8±3,7 years, senile - 81,9±4,5 years. The age variability transformation of venous vessels bandwidth of lungs, kidneys, heart, stomach and ileum were obligate.

Atomistic characterisation of Li+ mobility and conductivity in Li(7-x)PS(6-x)Ix argyrodites from molecular dynamics simulations, solid-state NMR, and impedance spectroscopy.

The atomistic mechanisms of Li(+) ion mobility/conductivity in Li(7-x)PS(6-x)I(x) argyrodites are explored from both experimental and theoretical viewpoints. Ionic conductivity in the title compound is associated with a solid-solid phase transition, which was characterised by low-temperature differential scanning calorimetry, (7)Li and (127)I NMR investigations, impedance measurements and molecular dynamics simulations. The NMR signals of both isotopes are dominated by anisotropic interactions at low temperatures.
