ФАКТОРЫ ВЗАИМНОГО ОТЯГОЩЕНИЯ МНОЖЕСТВЕННЫХ ХРОНИЧЕСКИХ ОЧАГОВ ИНФЕКЦИИ И ГЕНЕРАЛИЗОВАННОГО ПАРОДОНТИТА
Introduction. The Inflammatory Diseases of the Parodont (IDP) of generalized character are closely connected petrogenetically with internal pathology and are a serious factor of its burdening, forming a negative comorbidity. Pro-inflammatory reactions and metabolic shifts, such as oxidizing stress, violation of regulatory participation of the vital minerals at an imbalance of their distribution in biological environments are the inflammatory mechanisms uniting IDP with chronic inflammatory diseases of visceral of different localization. The objective of the study was identification of metabolic factors of pathogenetic community of GIDP and a comorbid chronic focal infection of different localization. Material and methods. The activity of systemic factors of inflammation were studied in the patients with generalized periodontitis (GP) of developed stage on a background of multiple chronic foci of infection: level and ratios of pro- and antiinflammatory cytokines – interleukins 2,6,10, TNF-α, C – reactive protein in comparison with the activity of oxidation of lipids, proteins, low molecular weight thiols, assessment of levels of Zn, Cu, Fe in biological environments and the hepsidin blood level. Results and discussion. Significantly more expressed metabolic disorders in comorbidity multiple chronic foci of infection and GP, than in the absence of periodontium lesions have been shown. Increased lipid peroxidation and free radical oxidation of thiols (p<0.01), increased levels of C – reactive protein level and pro-inflammatory cytokines (TNF-α, IL 6), and imbalance in the distribution of such trace elements as copper, zinc, iron in environments of organism were found in patients with combined pathology of comorbidity multiple chronic foci of infection and GP. Conclusions. Thus, the findings of the study demonstrate that formation of multiple chronic foci of infection in an organism is connected with increase of mediators of system inflammation in blood, disorders of redox metabolism and deficiency of such trace elements as Cu, Zn, Fe which are the key factors of a enzyme link of antioxidant protection.Введение. Воспалительные заболевания пародонта (ВЗП) генерализованного характера патогенетически тесно связаны с внутренней патологией и являются серьезным фактором ее отягощения, формируя негативную коморбидность. Воспалительными механизмами, объединяющими ВЗП с хроническими воспалительными заболеваниями внутренних органов различной локализации, являются провоспалительные реакции и метаболические сдвиги, такие как окислительный стресс, нарушение регуляторного участия жизненно важных микроэлементов при дисбалансе распределения их в биологических средах. Целью исследования явилась идентификация метаболических факторов патогенетической общности ГВЗП и коморбидной хронической очаговой инфекции разной локализации. Материал и методы. У больных генерализованным пародонтитом (ГП) развившейся стадии на фоне множественных хронических очагов инфекции (МХОИ) изучена активность системно-действующих факторов воспаления: уровень и соотношения про- и противовоспалительных цитокинов – интерлейкинов-2, 6, 10, TNF-α, С-реактивного белка – в сопоставлении с активностью окисления липидов, белков, низкомолекулярных тиолов, оценкой уровней Zn, Cu, Fe в биологических средах и гепсидина в крови. Результаты исследования. Показаны достоверно более выраженные метаболические нарушения при коморбидности МХОИ и ГП, чем при отсутствии признаков поражения пародонта. У больных с сочетанной патологией МХОИ и ГП было установлено повышение активности перекисного окисления липидов и свободно-радикального окисления тиолов (р<0,01), повышение уровня СРБ и провоспалительных цитокинов (TNF-α, IL-6) и разбалансировка распре- деления микроэлементов, таких как медь, цинк, железо в биосредах организма. Заключение. Таким образом, полученные данные свидетельствуют о том, что формирование множественных хронических очагов инфекции в организме связано с нарастанием в крови медиаторов системного воспаления, нарушениями окислительно-восстановительного метаболизма и дефицитом таких микроэлементов, как Cu, Zn, Fe – ключевых факторов ферментного звена антиоксидантной защиты.

Genotoksičnost metalnih nanočestica: osvrt na podatke istraživanja In vivo
With increasing production and application of a variety of nanomaterials (NMs), research on their cytotoxic and genotoxic potential grows, as the exposure to these nano-sized materials may potentially result in adverse health effects. In large part, indications for potential DNA damaging effects of nanoparticles (NPs) originate from inconsistent in vitro studies. To clarify these effects, the implementation of in vivo studies has been emphasised. This paper summarises study results of genotoxic effects of NPs, which are available in the recent literature. They provide indications that some NP types cause both DNA strand breaks and chromosomal damages in experimental animals. Their genotoxic effects, however, do not depend only on particle size, surface modifi cation (particle coating), and exposure route, but also on exposure duration. Currently available animal studies may suggest differing mechanisms (depending on the duration of exposure) by which living organisms react to NP contact. Nevertheless, due to considerable inconsistencies in the recent literature and the lack of standardised test methods - a reliable hazard assessment of NMs is still limited. Therefore, international organisations (e.g. NIOSH) suggest utmost caution when potential exposure of humans to NMs occurs, as long as evidence of their toxicological and genotoxic effect(s) is limited.S povećanjem proizvodnje i primjene niza različitih nanomaterijala (NM) raste i potreba istraživanja njihovih mogućih citotoksičnih i genotoksičnih učinaka kao i drugih štetnih učinaka na zdravlje u uvjetima profesionalne ili opće izloženost ljudi. Indikacije potencijanog oštećenja DNA kojeg uzrokuju nanočestice u velikoj mjeri proizlaze iz nedosljednih in vitro ispitivanja. Kako bi se razjasnili ti učinci, naglašena je potreba provedbe in vivo ispitivanja. Ovaj pregledni rad sažima rezultate procjene genotoksičnih učinaka nanočestica koji su objavljeni u novijoj stručnoj i znanstvenoj literaturi. Navedeni rezultati pokazuju da određene nanočestice uzrokuju lomove u molekuli DNA i oštećuju kromosome u eksperimentalnim životinjama. Njihovi genotoksični učinci ne ovise samo o veličini čestice, modifi kaciji površine (oblaganje čestice) i načinu izlaganja, već i o trajanju izloženosti nanočesticama. Postojeća istraživanja provedena na životinjama upućuju na različite mehanizme koji ovise o trajanju izlaganja i pomoću kojih živi organizmi reagiraju na doticaj s nanočesticama. Međutim postoje brojne nedosljednosti u novijoj literaturi, a standardne testne metode nisu dostupne pa je stoga pouzdanija procjena opasnosti od izlaganja nanomaterijalima u ljudi još uvijek veoma ograničena. Stoga se u međunarodnim dokumentima savjetuje oprez prilikom svakog izlaganja ljudi nanomaterijalima kako bi se spriječili mogući opći toksični genotoksični učinci
Application of the bacteriophage Mu-driven system for the integration/amplification of target genes in the chromosomes of engineered Gram-negative bacteria—mini review
The advantages of phage Mu transposition-based systems for the chromosomal editing of plasmid-less strains are reviewed. The cis and trans requirements for Mu phage-mediated transposition, which include the L/R ends of the Mu DNA, the transposition factors MuA and MuB, and the cis/trans functioning of the E element as an enhancer, are presented. Mini-Mu(LR)/(LER) units are Mu derivatives that lack most of the Mu genes but contain the L/R ends or a properly arranged E element in cis to the L/R ends. The dual-component system, which consists of an integrative plasmid with a mini-Mu and an easily eliminated helper plasmid encoding inducible transposition factors, is described in detail as a tool for the integration/amplification of recombinant DNAs. This chromosomal editing method is based on replicative transposition through the formation of a cointegrate that can be resolved in a recombination-dependent manner. (E-plus)- or (E-minus)-helpers that differ in the presence of the trans-acting E element are used to achieve the proper mini-Mu transposition intensity. The systems that have been developed for the construction of stably maintained mini-Mu multi-integrant strains of Escherichia coli and Methylophilus methylotrophus are described. A novel integration/amplification/fixation strategy is proposed for consecutive independent replicative transpositions of different mini-Mu(LER) units with “excisable” E elements in methylotrophic cells
