[Experimental morphological rationale for the use of cultures of multipotent mesenchymal stem cells in combination with biomaterials in the reconstruction of the pelvic floor].

Unlabelled: To date, descension of the pelvic floor is a fairly common gynecological pathology that requires surgical treatment. The development of cellular technologies suggests that the use of multipotent mesenchymal stem cells (MMSC) in the treatment of this pathology can stimulate the regeneration of damaged tissue and contribute to the reconstruction of the structures of the pelvic floor.

Objective: to evaluate the effectiveness of using MMSC in combination with biological and synthetic materials in vitro and in vivo with descension of the pelvic floor.

[Structural-morphological changes of the connective tissue of the vaginal mucosa and perineal skin in women with stress urinary incontinence].

Aim: To investigate the morphological and structural changes in the connective tissue of the vaginal mucosa and perineal skin in women with stress urinary incontinence.

Materials And Methods: From 2010 to 2013, 71 patients of reproductive age with stress incontinence were observed. The control group comprised 80 women, who also underwent biopsy of the vaginal mucosa and perineal skin.

Chemical control of semiconductor nanowire kinking and superstructure.

We show that methylgermane (GeH(3)CH(3)) can induce a transition from 111 to 110 oriented growth during the vapor-liquid-solid synthesis of Ge nanowires. This hydride-based chemistry is subsequently leveraged to rationally fabricate kinking superstructures based on combinations of 111 and 110 segments. The addition of GeH(3)CH(3) also eliminates sidewall tapering and enables Ge nanowire growth at temperatures exceeding 475 °C, which greatly expands the process window and opens new avenues to create Si/Ge heterostructures.

Acid-catalyzed conversion of sugars and furfurals in an ionic-liquid phase.

The reactivity of monosaccharides, furfural, and 5-hydroxymethyl-2-furfural (HMF) in the presence of a Brønsted acid (added as H(2)SO(4)) in the ionic liquid 1-butyl-3-methylimidazolium chloride (BMImCl) is investigated at 120 °C. Fructose is converted much faster than mannose, glucose, and xylose and yields HMF with high selectivity, even in the absence of acid. Conversion of mannose, glucose, and xylose involves more complex reaction networks.

[The effect of hemosorption on the glycoprotein concentration of the blood serum in inflammatory diseases of the large intestine].

71 patients with nonspecific diseases of the colon were examined before and after hemosorption for concentrations of seromucoid, orosomucoid, immunoglobulins G,M,A, C3 and C4 complement component fractions, haptoglobin, ceruloplasmin, alpha 1-antitrypsin, C-reactive protein, properdin, transferrin. It was found that hemosorption results in lowering of all the above concentrations in nonspecific ulcerative colitis, except seromucoid and orosomucoid in moderate and acute colitis. In response to hemosorption serum glycoproteins levels varied with the disease severity, its duration and metabolic activity of the liver.
