Background: The mini-invasive open posterior lumbar fusion procedure (mini PLIF) procedure is an alternative to standard open procedure (open PLIF) and is intended to reduce surgery-related trauma. The measuring of suitable biochemical factors enables objective comparison of the invasiveness of spinal surgery procedures. Methods: Prospectively collected data on myoglobin, creatine kinase, interleukin-6, C-reactive protein levels and intensity of low back pain and radicular pain in one-level mini PLIF and open PLIF procedures were analysed. The mini PLIF and the open PLIF groups included 27 and 23 patients, respectively. The collection of blood samples and clinical data were performed preoperatively and on postoperative days 1, 3 and 7. The non-paired t-test was used for statistical evaluation. Results: We did not found any statistically significant differences of myoglobin and creatine kinase levels between the groups. In the open PLIF group the IL-6 levels were significantly higher than in the mini PLIF group on postoperative day 3. CRP levels showed significant lower stress response in favour of the mini PLIF group on postoperative days 3 and 7. Levels of post-op low back pain on day 3 were significantly lower in mini PLIF group. Also intensity of radicular pain on day 1 and 3 were lower also mini PLIF group. Conclusion: The extent of myonecrosis was comparable in both techniques. The analysis of the IL-6 and CRP levels showed significantly lower systemic inflammatory response in mini PLIF technique. The mini PLIF technique provides transiently lower postoperative pain levels. © 2015 Polish Neurological Society. Source

Background: Anatomical malformations of the kidney and urinary tract account for 17% of pediatric renal transplantation procedures. Heat shock proteins (HSPs) are molecular chaperones with a protective function that promotes cell survival. HSP72 is an endogenous ligand for toll-like receptor TLR4, thereby stimulating innate immunity. Both in adults and children, decreased expression of HSP70s is associated with a number of kidney diseases. Objective: To assess the prevalence of HSPA1A G(190)C, HSPA1B A(1267)G, and TLR4 A(896)G polymorphisms in children who had undergone kidney transplantation. Patients and Methods: Genotypes were analyzed using allele-specific polymerase chain reaction in 41 pediatric recipients. Allelic prevalence was related to reference values in 65 age- and sex-matched healthy children. Results: Clinical data did not reveal a difference between any of the groups. HSPA1B (1267)GG genotype and HSPA1B (1267)G allele were observed more frequently in the transplant recipients compared with the control group: AA vs AG: odds ratio [OR], 12.6; 95% confidence interval [CI], 1.58100.0; P = .004; AA vs GG: OR, 20.80; 95% CI, 2.32187.00; P = .01; and A vs G: OR, 2.10; 95% CI, 1.193.07; P = .01. Furthermore, the prevalence of the HSPA1B (1267)GG genotype was greater in transplant recipients with vs without urinary tract malformations: AG vs GG: OR, 0.10; 95% CI, 0.090.48; P = .007. No differences were observed in the other studied polymorphisms. Conclusion: Our findings suggest an association between the carrier status of HSPA1B (1267)G with urinary tract malformations, leading to end-stage renal disease requiring kidney transplantation. This observation raises further questions about the clinical and therapeutic relevance of this polymorphism to pediatric nephrology. © 2010 Elsevier Inc. Source

Waste disposal sites from non-ferrous metal industry constitute environments very hostile for life due to the presence of very specialized abiotic factors (pH, salt concentration, heavy metals content). In our experiments microflora of two waste disposal sites in Slovakia-brown mud disposal site from aluminium production near Ziar nad Hronom and nickel sludge disposal site near Sered-was analyzed for cultivable bacteria. Isolated bacteria were characterized by a combination of classical microbiological approaches and molecular methods and the most of isolated bacteria shown a poly-extremotolerant phenotype. The most frequently halotolerant (resistant to the high level of salt concentrations) and alkalitolerant (resistant to the high pH level) bacteria belonging to the Actinobacteria class were detected. The most of bacteria shown very high level of heavy metal resistance e.g. more than 500 μg/ml for Zn2+ or Cu2+. Based on our data, waste disposal sites thus on one side represents an important environmental burden but on other side they are a source of new poly-extremotolerant bacterial strains and species possibly used in many biotechnology and bioremediation applications. © 2015 Peter Pristas et al.

The ability of MALDI TOF MS (matrix-assisted laser desorption ionisation time-of-flight mass spectrometry) to identify cultivable microflora from two waste disposal sites from non-ferrous metal industry was analysed. Despite the harsh conditions (extreme pH values and heavy metal content in red mud disposal site from aluminium production or high heavy metal content in nickel sludge), relatively high numbers of bacteria were recovered. In both environments, the bacterial community was dominated by Gram-positive bacteria, especially by actinobacteria. High-quality MALDI TOF mass spectra were obtained but most of the bacteria isolates could be not identified using MALDI Biotyper software. The overall identification rate was lower than 20 %; in two of the environments tested identification rates were lower than 10 %. As a dominant bacterial species, Microbacterium spp. in drainage water from an aluminium red mud disposal site near Žiar nad Hronom, Bacillus spp. in red mud samples from the same site, and Arthrobacter spp. from nickel smelter sludge near Sered were identified by a combination of the Biolog system and 16S rRNA sequence analysis. As the primary focus of the MALDI TOF MS-based methodology is directed towards medically important bacteria, reference database spectra expansion and refinement are needed to improve the ability of MALDI TOF MS to identify environmental bacteria, especially those from extreme environments. © 2014 Institute of Chemistry, Slovak Academy of Sciences.

Brown mud is a waste by-product of alumina production by Bayer process. Due to extensive sodium hydroxide use in the process, brown mud disposal site near Ziar nad Hronom (Banska Bystrica region, Slovakia) and drainage water are ones of the greatest environmental burdens in Slovakia. Drainage water from this landfills has pH value higher than 13, and it contains many heavy metals and elevated salt content. In our experiments, relatively numerous bacterial population was detected in the drainage water with frequency of about 80 cfu/ml using cultivation approach. The alkalitolerant heterotrophic isolates were identified by combination of MALDI-TOF and 16S rDNA analysis. Drainage water population was dominated by Actinobacteria (Microbacterium spp. and Micrococcus spp.) followed by low G + C-content gram-positive bacteria (Bacillus spp.). Two isolates belonged to gram-negative bacteria only, identified as Brevundimonas spp. Phylogenetic and biochemical analyses indicate that nearly half of the bacteria isolated are probably representatives of a new species. Brown mud disposal site is proposed as a source of new bacterial taxa possibly used in bioremediation processes. © 2015, Springer-Verlag Berlin Heidelberg. Source
