This paper addresses the scar tissue maturation process that occurs stepwise, and calls for reliable classification. The structure of collagen imaged by nonlinear optical microscopy (NLOM) in post-burn hypertrophic and mature scar, as well as in normal skin, appeared to distinguish these maturation steps. However, it was a discrimination analysis, demonstrated here, that automated and quantified the scar tissue maturation process. The achieved scar classification accuracy was as high as 96%. The combination of NLOM and discrimination analysis is believed to be instrumental in gaining insight into the scar formation, for express diagnosis of scar and surgery planning. © 2012 WILEY-VCH Verlag GmbH & Co.

The paper reviews the literature on the role of hyperuricemia as a risk factor for chronic kidney disease and as one of the factors for the progression of existing kidney disease. It gives epidemiological information on a relationship between hyperuricemia and kidney lesion. The mechanisms for the damaging action of uric acid on kidney tissue, which have experimentally and clinically observed, are considered. The main areas of hyperuricemia correction and its place in the total nephroprotection strategy are defined.

Aim: To determine the nature and magnitude of changes in the detectable serum and urinary biomarkers of water-salt metabolism in patients with proteinuric forms of chronic glomerulonephritis (CGN), their importance for assessing the activity and prognosis of the disease. Subjects and methods: Forty-seven patients with CGN were examined. Group 1 included 10 patients with nephrotic syndrome (NS) and decreased renal function; Group 2 comprised 16 patients with persistent NS and normal renal function; Group 3 consisted of 10 patients with partial remission of NS; Group 4 included 11 patients with active hematuric CGN. A control group consisted of 9 healthy individuals matched for gender and age with the patients with CGN. The serum level of copeptin and the urinary excretion of aquaporine-2 (AQP-2) and kidney injury molecule-1 (KIM-1) were determined by indirect enzyme-linked immunosorbent assay (ELISA). Results: In the NS patients with and without renal dysfunction, the serum copeptin concentration was significantly higher than that in those with partial remission of NS or hematuric CGN and in the controls. In the patients with hematuric CGN, this indicator was virtually different from that in the control group. Urinary AQP-2 excretion was significantly similar in 3 NS groups. In the patients with hematuric CGN, the urinary AQP-2 concentration was higher than that in those with NS, but it was significantly lower than in the control group. The highest urinary excretion of KIM-1 was found in the patients with NS and diminished renal function while its excretion was significantly lower in the patients with NS and stable renal function, as in those with partial remission of NS. The lowest values were seen in the patients with hematuric CGN and in the control group; the differences between these groups were statistically insignificant. Correlation analysis showed that there was an inverse correlation between serum copeptin and urinary AQP-2 levels and between urinary AQP-2 and KIM-1 levels. Conclusion: Serum copeptin levels and urinary AQP-2 secretion may be used to assess the activity of CGN and NS and to evaluate therapeutic effectiveness. The determination of urinary KIM-1 excretion may be of the same practical value in patients with NS. It has been shown that the concentrations of copeptin, APQ-2, and KIM-1 may be used as a differential diagnostic criterion for hematuric CGN.

Aim. To study intraventricular asynchrony and effects of pacemaker implantation on asynchrony severity in patients with rhythm and conduction disorders. Material and methods. The study of 46 patients with cardiac arrhythmia (atrial fibrillation, sick sinus syndrome, AB-block of the third degree) included such examinations as echocardiography, tissue dopplerography (PWTDl) before pacemaker implantation and 7 days after it. Electromechanic systolic and diastolic myocardial asynchrony was assessed by intraventricular heterogeneity index (IHb, IHm, TSD) in 8 segments of the left ventricle (LV) at the basal and mean levels. Values obtained in examination of 32 healthy volunteers were considered normal. Results. Parameters of systolic and diastolic asynchrony in patients with cardiac arrhythmia significantly differ from normal ones. Basal LV diastolic asynchrony was detected in 41-48% patients, systolic one -in 62-100%, systolodiastolic - in 41% cases. Pacemaker implantation into the right heart significantly reduces LV systolic asynchrony while diastolic one was unaffected in an early postoperative period. The best sensitivity in detection of systolic asynchrony is achieved with TsSD index. Informative value of diastolic asynchrony parameters is much less than of the systolic one. Conclusion. Indices of systolic asynchrony (TsSD, IhbS, IhmS) can be used for heart condition control after pacemaker implantation.

A rare variant of nephropathy in multiple myeloma (MM) is reported. Nephropathy is characterized basing on the study of nephrobiopsy with light, immunofluorescent and electron microscopy. A repeat biopsy of the kidney was made after achievement of a complete clinicohematological remission. A MM patient's nephrobiopsy in a picture of glomerulonephritis had 3 types of deposits: granular, irregular fibrils of 12 nm in diameter and microtubes organized in bunches 19 nm in diameter. Congo red test was negative, cryoglobulinemia was absent. Immunofluorescent test detected deposit of monoclonal IgG in the mesangium and glomerular basal membrane (GBM) corresponding to monoclonal type of monoclonal secretion. After treatment and achievement of remission, neither IgG no light chains were found in nephrobiopsy. Electron microscopy registered complete resorption of granular deposits and microtubes with formation of electron-transparent cavities. However, fibrils seen before treatment only in mesangium appeared in the above hollow cavities. The presence of such fibrils in the mesangium and GBM did not influence clinical picture of the disease. After achievement of remission the patient had no clinical and laboratory signs of nephropathy, only insignificant selective glomerular proteinurea was observed (0,5 g/l). Thus, granular deposits and microtubes contained paraprotein, they were completely resorbed after achievement of MM remission. Fibrils seem to have another genesis unrelated to monoclonal gammapathy.

Somatic genome variations (mosaicism) seem to represent a common mechanism for human intercellular/interindividual diversity in health and disease. However, origins and mechanisms of somatic mosaicism remain a matter of conjecture. Recently, it has been hypothesized that zygotic genomic variation naturally occurring in humans is likely to predispose to nonheritable genetic changes (aneuploidy) acquired during the lifetime through affecting cell cycle regulation, genome stability maintenance, and related pathways. Here, we have evaluated genomic copy number variation (CNV) in genes implicated in the cell cycle pathway (according to Kyoto Encyclopedia of Genes and Genomes/KEGG) within a cohort of patients with intellectual disability, autism, and/or epilepsy, in which the phenotype was not associated with genomic rearrangements altering this pathway. Benign CNVs affecting 20 genes of the cell cycle pathway were detected in 161 out of 255 patients (71.6%). Among them, 62 individuals exhibited >2 CNVs affecting the cell cycle pathway. Taking into account the number of individuals demonstrating CNV of these genes, a support for this hypothesis appears to be presented. Accordingly, we speculate that further studies of CNV burden across the genes implicated in related pathways might clarify whether zygotic genomic variation generates somatic mosaicism in health and disease.
