Résumé :

Biochemical markers for the assessment of aquatic environment contaminationThe need for assessment of aquatic ecosystem contamination and of its impact on water dwelling organisms was developed in response to rising aquatic environmental pollution. In this field study, liver enzymes of phase I and phase II of xenobiotic transformation, namely cytochrome P450, ethoxyresorufin-O-deethylase, glutathione-S-transferase and tripeptide glutathione were used to assess the contamination of the aquatic environment at different rivers in the Czech Republic. The indicator species selected was the male chub (Leuciscus cephalusL.) and male brown trout (Salmo trutta fario). Chemical analyses included also the assessment of the most important inductors of previously mentioned biochemical markers. The major inductors of monitored biomarkers are industrial contaminants which belong to a large group of organic pollutants (PCB, PAH, PCDD/F, DDT, HCH, HCB and OCS), persistent in the environment. Four different groups of river basins were assessed: the River Tichá Orlice and its tributary the Kralický brook; important tributaries of the River Elbe (the rivers Orlice, Chrudimka, Cidlina, Jizera, Vltava, Ohře and Bílina); major rivers in the Czech Republic (the rivers Lužnice, Otava, Sázava, Berounka, Vltava, Labe, Ohře, Svratka, Dyje, Morava and Odra) and the River Vltava. The use of the biochemical markers together with chemical analyses seems to be an effective way to monitor the quality of aquatic environment.

Résumé :

SUMMARYA complete developmental sequence ofLeishmania mexicanahas been produced in axenic culture for the first time. This was achieved by manipulation of media, pH and temperature conditions over a period of 16 days. All experiments were initiated with lesion amastigotes that were transformed to multiplicative promastigotes by culture in HOMEM, 10% foetal calf serum, pH 7·5, at 25 °C. Metacyclogenesis was induced by subpassage in Schneider'sDrosophila medium, 20% foetal calf serum, pH 5·5, and the resulting forms transformed to axenically growing amastigotes by subpassage in the same medium and raising the temperature to 32 °C. Parasites from each day were characterized with respect to their general morphology using light microscopy of Giemsa-stained smears, and biochemically by analysis of total protein content, proteinases, nucleases and secretory acid phosphatase. The results demonstrated that the three main stages identified - amastigotes, multiplicative promastigotes and metacyclic promastigotes - each exhibited the expected suite of biochemical properties. Further, the changes in morphology observed as the developmental sequence proceeded from stage to stage were accompanied by appropriate changes in biochemical properties. These results provide both useful biochemical markers and a culture system in which to examine the regulation of differentiation and transformation during theLeishmanialife-cycle.

Résumé :

We have examined the modifications occurring during the transformation of phagosomes into phagolysosomes in J-774 macrophages. The use of low density latex beads as markers of phagosomes (latex bead compartments, LBC) allowed the isolation of these organelles by flotation on a simple sucrose gradient. Two-dimensional gel electrophoresis, immunocytochemistry, and biochemical assays have been used to characterize the composition of LBC at different time points after their formation, as well as their interactions with the organelles of the endocytic pathway. Our results show that LBC acquire and lose various markers during their transformation into phagolysosomes. Among these are members of the rab family of small GTPases as well as proteins of the lamp family. The transfer of the LBC of lamp 2, a membrane protein associated with late endocytic structures, was shown to be microtubule dependent. Video-microscopy showed that newly formed phagosomes were involved in rapid multiple contacts with late components of the endocytic pathway. Collectively, these observations suggest that phagolysosome formation is a highly dynamic process that involves the gradual and regulated acquisition of markers from endocytic organelles.

Résumé :

Genetic transformation is a powerful tool for plant breeding and genetical, physiological or biochemical research, consequently it is an extremely dynamic field. Transgenic plants are commonly used to complete or substitute mutants in basic research, helping the studies of complex biological situations such as pathogenesis process, genome organization, light reception and signal transduction. In this review, recent approaches for foreign gene introduction (e.g. Agrobiolistics, whole tissue electroporation, in planta Agrobacterium transformation), screening (reporter gene possibilities and performance) and transformant selection (ipt selective marker) are discussed. Transgene expression and mechanisms underlying (trans)gene inactivation are presented. Practical applications of genetically modified plants, field tests and commercial transgenic crops worldwide and in Brazil are listed, as well as the main traits and species modified. Potential uses of transgenic plants for animal compound production, biological remediation and synthetic polymer assembly are also shown.

Résumé :

This article analyzes the genetic markers of planocellular head and neck cancers from the aspect of theoretical basis for their identification and application, actual state of research in this field and benefit that could be expected from their introduction into clinical practice. In spite of unquestionable progress of diagnostics and treatment of planocellular cancer of the head and neck, there has been no evident improvement of five-year survival during the last two decades, due to which the attempts have been made for global diagnostics and therapeutic orientation to be directed towards the detection of changes at molecular level. Tumor markers are defined as biochemical indicators of the existing tumors. They include the structural changes of nucleic acids (DNA and RNA), when genetic markers are in question, the development of new or modified antigens at the cell surface, the synthesis of specific plasma proteins and eutopic/ectopic hormone production. The changes of gene structure, in tumor tissue or somatic cells that are easily accessible are verified by molecular-biological techniques, and the initial step is the amplification of the genome part which is considered significant (polymerase chain reaction technique). The presence or absence of specific tumor marker, as well as its phenotypic characteristics may be verified in tumor tissue or body fluids by immunochemical methods including the immunohistochemistry before all, owing to availability of a large number of mono- and polyclonal antibodies. While some fields of oncology have been using the benefits of specific tumor markers for years, no adequate solution for the treatment of planocellular head and neck cancers can be seen yet. Currently, it is clear that there is not a single specific marker for head and neck cancer or for the group of planocellular cancers as a whole, while the literature is plentiful of different and very often contradictory findings. The greatest attention has been paid to the study of P53 gene, either isolated or in the group of other potential markers such as cycline D1, growth transformation factor, vascular endothelium growth factor, E-katherin and collagen VII. The insights obtained by these studies have encouraged the attempts to use the genetic markers for managing several crucial clinical issues, such as early detection of premalignant and malignant lesions, early detection of local recurrence and distant metastasis, early prevention of secondary tumors, and especially, the selection of patients for specific therapy.

Résumé :

The pathophysiological mechanisms of migraine transformation are debated. Modifications of plasma oxidative stress biomarkers have been described in chronic migraine. OnabotulintoxinA (BoNT/A) treatment, approved for chronic migraine prophylaxis, possibly reduces pain neurotransmitters release and oxidative stress products. Aims of our study were to investigate differences in the levels of selected plasmatic oxidative stress biomarkers (Advanced Oxidation Protein Products (AOPP), Ferric Reducing Antioxidant Power (FRAP), Thiolic Groups (SH)) comparing chronic migraineurs (CM) and healthy controls (HC). We also explored possible clinical and biochemical modifications in the CM group after six months of treatment with BoNT/A. At the baseline, we found higher values of AOPP (p < 0.001), and lower values of SH (p < 0.001) and FRAP (p = 0.005) in the CM group. At the six-month follow-up we found a reduction of AOPP (p < 0.001) and an increase of FRAP (p < 0.001) and SH (p = 0.023) within the CM group. BoNT/A treatment improved migraine symptoms in the CM group. We confirmed previous reports of imbalanced antioxidant mechanisms in chronic migraine showing lower antioxidant capacities in patients than controls. BoNT/A improved the levels of plasma oxidative stress biomarkers and confirmed its role as an effective prophylactic treatment for CM. Other studies should investigate the potential antioxidant properties of BoNT/A treatment.

Résumé :

The EC directive REACH (EC1907/2006) sets, amongst others, the need for all the chemicals to be tested for their carcinogenic potential. In vitro assays can provide a fast and reliable tool for screening purposes. The Cell Transformation Assay (CTA) is one of the in vitro assays in the most advanced phase of the validation process and the only one able to evaluate both the genotoxic and the non-genotoxic potentials. The evaluation of results of the CTA is based on the scoring of transformed colonies (foci) by a trained expert on the basis of their morphological features. Levels of cell packing and multilayered growth, as well as fibroblastic shape of cells, criss-crossing and invasion of the surrounding monolayer features are evaluated for classification. While the decision making process is based on standard criteria, their interpretation is potentially biased, especially in borderline cases, due to a certain degree of subjectivism inherent in the evaluation of qualitative features. This aspect is critical towards the international validation of the CTA assay: subjectivity driven error might in fact result in under or over estimation of the carcinogenic potential of tested compounds. In this work, different approaches were used to develop an objective method to give decisional support to the operator in the classification procedure. Biological markers related to the transformation process (p53, cx43), and to a general cell stress (Hsp70) were analyzed. A novel technique for the in focus localization of biological markers of transformation was developed. RNA whole genome screening was used to set the conditions for future molecular characterization of foci-derived cell lines. A novel, Quantitative Index of Dissimilarity has been obtained by statistical descriptors capturing morphological features and employing an unsupervised image analysis approach, in order to help the operator in the decisional process of scoring the borderline cases.

Texte intégral

Résumé :

This study has investigated potential biochemical markers of pulmonary oxygen toxicity (POT). Toxicity was investigated in male Sprague Dawley rats exposed to oxygen partial pressures ranging from 0.21-2.5 bars. It is known that prolonged exposure to 1 bar of oxygen damages pulmonary endothelial cells and so the biochemical functions of these cells have been studied. Control isolated perfused rat lungs were able to clear and/or metabolise a wide range of substances including 5-HT, PGE2, bradykinin, and angiotensin 1, all endothelial cell functions. As expected 5-HT clearance was compromised in isolated perfused rat lung obtained from rats exposed to 1 bar of oxygen, confirming endothelial cell damage. However the clearance of 5-HT by lungs obtained from rats exposed to 2.5 bars was normal, implying that the site of toxicity is different at these partial pressures. In addition enhancement of toxicity by vitamin E deficiency was not associated with endothelial cell damage at 2.5 bar. At the molecular level oxygen free radicals are thought to be the causative agents of POT. The radicals are reputed to damage lipids, but a process of peroxidation. One of the lipid fragment products of ω6 polyunsaturated fatty acids is n-pentane, a compound which is excreted on the breath. Monitoring of this compound during exposure to 0.21, 1.0, 2.5 bars of oxygen even in vitamin E deficient rats did not show a rise in pentane expiration in response to oxygen exposure. This implies that peroxidation of ω6 polyunsaturated fatty acids did not take place, although other lipids may have been peroxidised. In conclusion the site of POT may depend on the partial pressure of oxygen. Endothelial cell damage is probably absent during exposure to 2.5 bars of oxygen. In addition n-pentane monitoring, a reputed marker of POT, failed to reveal lipid perodixation during exposure to hyperoxia.

Résumé :

The project objective was to develop a reliable selection procedure to match contact lens materials with individual wearers by the identification of a biochemical marker for assessment of in-eye performance of contact lenses. There is a need for such a procedure as one of the main reasons for contact lens wearers ceasing wearing contact lenses is poor end of day comfort i.e. the lenses become intolerable to the wearer as the day progresses. The selection of an optimal material for individual wearers has the potential benefit to reduce drop Qut, hence increasing the overall contact lens population, and to improve contact lens comfort for established wearers. Using novel analytical methods and statistical techniques, we were able to investigate the interactions between the composition of the tear film and of the biofilm deposited on the contact lenses and contact lens performance. The investigations were limited to studying the lipid components of the tear film; the lipid layer, which plays a key role in preventing evaporation and stabilising the tear film, has been reported to be significantly thinner and of different mixing characteristics during contact lens wear. Different lipid families were found to influence symptomatology, in vivo tear film structure and stability as well as ocular integrity. Whereas the symptomatology was affected by both the tear film lipid composition and the nature of the lipid deposition, the structure of the tear film and its stability were mainly influenced by the tear film lipid composition. The ocular integrity also appeared to be influenced by the nature of the lipid deposition. Potential markers within the lipid species have been identified and could be applied as follows: When required in order to identify a problematic wearer or to match the contact lens material to the contact lens wearer, tear samples collected by the clinician could be dispatched to an analytical laboratory where lipid analysis could be carried out by HPLC. A colorimetric kit based on the lipid markers could also be developed and used by clinician directly in the practice; such a kit would involve tear sampling and classification according to the colour into "Problem", "Border line" and "Good" contact lens wearers groups. A test kit would also have wider scope for marketing in other areas such as general dry-eye pathology.

Résumé :

This work focused on the application to growth studies of the assay for pyridinium crosslinks in urine. The study showed the existence of a nyctohermeral rhythm of crosslink excretion in children, with a peak during the night or early in the morning, and pointed out between-day fluctuations of excretion (17% for Pyd and 19% for Dpd). The study also showed that urinary crosslinks were significantly related to anthropometric estimates of skeletal mass and that such estimates should be used to account for size differences between individuals. Cross-sectional observations on 272 children (3-18 years) showed a parallelism between the height velocity curve and the age profile of crosslink excretion. In 3-5 year old children, the study pointed out a positive relationship with monthly height velocity (R = 0.20); 5-month integrated values of excretion were also correlated to 5-month height velocity (R = 0.78 for Pyd; R = 0.73 for Dpd). Urinary crosslinks were normal in 53 children (124±34 months) affected by miscellaneous conditions leading to growth defects, in 14 children (117±47 months) affected by coeliac disease, nor in 20 children affected by GH deficiency or short stature (aged 117±20 months); they were in the high range in 7 girls with Turner's syndrome, in 58 malnourished boys (14±14 months), urinary crosslinks were proportional to the degree of wasting and were positively correlated to the rate of height gain during hospitalisation. In children treated with Growth Hormone, except those affected by Turner's syndrome, crosslinks could predict 6-month growth after the first month of therapy.

Résumé :

The establishment of physiological norms for psychologically hardy vs. non-hardy individuals was attempted by examination of levels of salivary cortisol and urinary norepinephrine before and after a mid-term examination stressor. Normative data was collected on the reported frequency of stressors and their severity one week prior to the examination, and self-reported ratings of stress immediately prior to the examination. Performance on the examination as a function of hardiness was explored. Associations between demographic variables and psychological hardiness were also studied. Results from this study were inconclusive in establishing physiological norms for psychologically hardy individuals. Associations were found between: 1) hardiness and frequency of stressors; 2) hardiness and age; and 3) self-reported ratings of stress and anxiety as measured by the State-Trait Anxiety Inventory (STAI).

Résumé :

The genus Aspergillus includes a diverse group of filamentous fungi that are widely distributed in nature, commonly found in soil. The Aspergilli include species that can be beneficial or detrimental to humans, so detection and accurate identification of these organisms can be very important. Morphology and genetic sequence analysis are well established methods for classifying and identifying fungi, but morphology remains a widely used technique that generally works well for Aspergilli. However, some organisms may be misidentified due to atypical morphology and some hidden (cryptic) species may not be recognized as different from named species based on readily observable traits. In this study, reference strains of different Aspergillus species, Penicillium chrysogenum, Candida albicans, and Cryptococcus neoformans were characterized using LC/MS and GC/MS biochemical profiling techniques in order to find specific small molecules, peptides or biochemical profiles that can be used in addition to established methods to detect and classify Aspergilli to the species level. Subsequently, analytical methods developed for characterizing the reference strains were applied, along with morphology and PCR, to characterize and identify several laboratory and field isolates. Some unique compounds and biochemical patterns did emerge from small molecule profiling that could be used for classifying Aspergilli, but protein profiling by LC/MS/MS was a much more effective approach. Tandem mass spectra from LC/MS/MS of tryptic peptides from fungal proteins were searched against protein databases and matched to theoretical spectra derived from those databases. Many of the amino acid sequences detected were taxonomically diagnostic for classifying Aspergillus species. Protein profiling also provided a great deal of additional biochemical information on the test organisms by identifying the predominant enzymes and structural proteins present under different experimental conditions and may find broader application for identifying and studying other organisms.

Résumé :

Calcific Aortic Valve Disease (CAVD) is the third most common cause of cardiovascular disease, affecting nearly 5 million people in the United States alone. It is now the most common form of acquired valvular disease in industrialized countries and will likely affect more individuals in the coming years as the prevalence increases with life expectancy. It is known that the progression of CAVD is closely related to the behavior of aortic valve interstitial cells (AVICs); however the cellular mechanobiological mechanisms leading to dysfunction remain unclear. Generally, CAVD is characterized by the formation of calcified AVIC aggregates with an apoptotic core. These aggregates increase the leaflet stiffness and impede normal valve function. Multiple studies have investigated the effects of various biochemical cues on this process, such as transformation growth factor β1 (TGF-β1), on the regulation of nodule formation [1]. Additionally, Yip et al revealed that matrix stiffness controls nodule formation in vitro, with stiffer substrates promoting apoptotic nodule formation, while compliant substrates generated nodules containing cells with osteoblast markers [2]. This suggests that matrix stiffness is involved in the regulatory mechanisms of nodule formation and may initiate different types of nodule formation (i.e. osteogenic vs. dystrophic). In the current study, we examined the synergistic role of strain and TGF-β1 in the generation of calcified nodules AVICs.

Résumé :

The concept of efficient utilisation of renewable bio-based materials (biomass feedstock) is the driving force in the green transformation to a more sustainable and circular society. Biorefineries or biochemical platforms convert and utilise different sources of biomass into fuels and other beneficial derivates like fibres and other bio-based chemicals. These can be used as building blocks for many potentially useful applications. In this review, we shall describe the current state of the art and trends in the conversion of lignocellulosic feedstock into materials which can be primarily used in packaging applications. The three main constituents (cellulose, hemicellulose and lignin) are being re-engineered into new products with higher added value. The main goal of all these downstream products is that they do not compete with animal feed and food applications. The main downstream products of different kind of transformations are different natural fibres which can be further processed into micro or nano fibrillated state and used for a broad application of fields from ink, adhesive and packaging materials. Also, fibres and its derivates can be bonded successfully into bio-composites or fibre-based foams applications for the protective packaging applications. Hemicellulose, as a second most abundant component, has been researched for applications in adhesives and paper and paperboard coatings. Lignin which is currently utilised as an energy source for the paper industry, has been recently actively researched. Lignin-based biopolymers have a potential to be used in many different applications from additives in the barrier coatings on the packaging to active packaging and even as lignin-based foams. All these applications are currently in the development stages and cover niche market segments, but are expected to grow and to be used in future markets.

Résumé :

The article is devoted to determining the correlation between the biochemical parameters of the blood serum of patients with COVID-19. Concentrations of the main biochemical markers of inflammation at different stages of lung tissue damage by a new coronavirus infection with further correlation analysis of blood parameters were determined. The experiment of the study showed that there is a high correlation between the biochemical parameters of blood. Its sig-nificance helps to determine the sequence of the manifestation of biochemical markers of in-flammation and proves the mechanism of changes in the biochemical picture of blood in COVID-19, which we assume.

Résumé :

The objective was to screen maize lines for their ability to express resistance based on biochemical traits. Cultivars were screened for retention of the hydroxamic acid DIMBOA and the synthesis of phenols (based on anthocyanin production) as markers for resistance. Lines were selected and inoculated with fungal pathogens (Exserohilum turcicum, Puccinia sorghi, Cochliobolus heterostraphus, Colletotricum graminicola.), and the Maize Dwarf Mosaic and Johnson Grass Mosaic viruses. Lines were screened in the field and greenhouse. Results showed that lines selected for augmented phenol synthesis do exhibit heightened levels of resistance to fungal pathogens. Isolation of mRNA followed by northern analyses for expression of A1 (dihydroflavanol reductase) and peroxidase confirmed that genes for these enzymes were turned on in response to inoculation of lines predicted to exhibit resistance. Peroxidase and b-1,3-glucanase were assayed in breeding lines having or lacking the se gene. A specific ionically-bound peroxidase isozyme and a b-1,3-glucanase isozyme were revealed in lines having the se gene. Data suggest that peroxidase and b-1,3-glucanase isozymes, may be considered as markers to identify resistance to E. turcicum in maize genotypes with the se gene.
