Abstract
This study aimed to evaluate the antioxidant potential of autochthonous Hydnum repandum through LC-MS/MS profiling, total phenolic content (TP), total protein content (TPR), and antioxidant capabilities (DPPH, ABTS, and FRAP assays) across various extracts (CHCl3, acetone, 70% EtOH, 80% MeOH, and hot water). LC-MS/MS analysis revealed a predominant presence of quinic acid in polar solvents (ranging from 531.37 to 676.07 ng/mL), while EtOH and MeOH extracts exhibited elevated total phenolic levels (27.44 ± 0.32 and 28.29 ± 3.62 mg GAE/g d.w., respectively). Impressively, H. repandum showcased remarkable antioxidant properties, as evidenced by its FRAP values (57.29 to 199.96 mg AAE/g d.w.), ABTS values (5.69 to 29.95 mg TE/g d.w.), and IC50 values in the DPPH assay (91.40 to 372.55 μg/mL), which exhibited a strong correlation with TP. Notably, the acetone extract exhibited the most robust antioxidant activity where the highest TPR was observed, suggesting synergism of primary and secondary metabolites.

Abstract
Acrylamide (AA) is a well-known industrial monomer with carcinogenic, mutagenic, neurotoxic and endocrine disruptive effects on living organisms. AA has been the subject of renewed interest owing to its presence in various food products. We investigated the potential adverse effects of oral AA treatment on the endocrine pancreas of juvenile rats using histochemical, immunohistochemical, stereological and biochemical methods. Thirty juvenile male Wistar rats were divided into one control and two AA treatment groups: one treated with 25 mg/kg AA and the other treated with 50 mg/kg AA for 21 days. We found a significant decrease in β-cell mass. The significant decrease in β-cell optical density and unchanged blood glucose levels indicate that normoglycemia in AA treated rats may result from intensive exocytosis of insulin-containing secretory granules. By contrast with β-cells, we observed increased α-cell mass. The slight increase in α-cell cytoplasmic volume suggests retention of glucagon in α-cells, which is consistent with the significant increase in α-cell optical density for AA treated animals. The number of islets of Langerhans did not change significantly in AA treated groups. Our findings suggest that AA treatment causes decreased β-cell mass and moderate α-cell mass increase in the islets of Langerhans of juvenile male Wistar rats.

Abstract
The study evaluated the effects of waterborne pollutants from the Tamiš River on gill histology and possible differences in gill reaction patterns between three freshwater fish species, pike Esox lucius L. 1758, pike-perch Sander lucioperca (L. 1758) and wels catfish Silurus glanis L. 1758 from the Tamiš River. Gills from analysed fish species showed moderate to intense histopathological alterations. The most frequent progressive alteration was hyperplasia of epithelium, whereas the most frequent regressive alteration was epithelial lifting. Circulatory disturbances were most often manifested in the form of hyperaemia. During comparative analysis, differences in gill indices, reaction and alteration indices, as well as in gill and filament prevalence between analysed species, were observed. Although all analysed fish species did show both progressive and regressive alterations, there was a significant difference in the level of expression of these reaction patterns. Gill index obtained for pike clearly stands out as the lowest. Wels catfish showed the highest progressive reaction index, significantly higher in comparison with the other two species (P < 0.05), while pike-perch showed the highest regressive reaction index, also significantly higher in comparison with the other species (P < 0.001). These results may implicate species-specific gill reactions and thus present a useful tool for better understanding toxic mechanisms of various pollutants.

Abstract
Aromatic plants are among the most important sources of biologically active
secondary metabolites, with high antimicrobal potential. This study was
carried out to examine in vitro antifungal activity of Foeniculum vulgare
(Apiaceae), Carum carvi (Apiaceae) and Eucalyptus sp.(Myrtaceae) essential
oils against three Candida albicans strains of different origin
(laboratory-CAL, human pulmonary-CAH and ATCC10231-CAR). The essential oils
were screened on C. albicans using disc and well-diffusion and microdilution
method, and compared to Nystatine and Fluconazole as standard anti-mycotics.
The activity of tested oils was expressed by inhibition zone diameter (mm),
minimum inhibitory concentration (MIC) and minimum fungicidal concentration
(MFC) (mg/ml). The results indicated that studied essential oils show
antifungal activity against all three isolates of C. albicans. It was
observed that each oil exhibits different degree of antifungal activity
depending on the oil concentration applied as well as on analyzed strain of
C. albicans. Carum carvi demonstrated the strongest antifungal effect to all
tested strains, showing the lowest MIC values (0.03mg/ml for CAL, 0.06mg/ml
for CAH, and 0.11mg/ml for CAR, respectively). Eucalyptus sp. exhibited the
lowest antifungal activity, with MIC values ranging from 0.11 mg/ml for CAL
to 0.45 mg/ml for both CAH and CAR.

Abstract
In the frame of biodiversity investigation of the Republic of Serbia, the investigation of the presence and the diversity of macrofungi of the Zasavica Special Nature Reserve (North Serbia) has been undertaken. Relatively poor generic diversity of macrofungi was recorded with domination of ecological group of wood-decaying species. Even though being preliminary, our results point to the necessity of conservation and protection of recent fungal diversity but, in our opinion, not by making a so-called 'Red list of endangered species', which, due to the lack of information and very poor evidence on this group of organisms in our country, are extremely unreliable and therefore disputable, but rather through the very short list of a few not endangered species, conditionally called 'White list of not endangered fungal species', if such species recently exist et all.

Abstract
As a result of an interest in natural derived metabolites around the world higher fungi (Basidiomycotina) have taken on great importance in biochemical investigations. A large number of structurally divergent compounds - both cellular components and secondary metabolites - have been extracted and found to possess significant biological activity, such as an immunomodulative effect on the human body. Effects of fungal biomolecules as potential natural antioxidants have not been examined so far. Biochemical analysis have included in vitro testing of the influence of different extracts (water methanol, chloroform) of selected fungal sporocarps on Fe2+/ascorbate-induced lipid peroxidation (LP) in a lecithin liposome system by TBA assay, as well as various other procedures. Qualitative analysis by TLC revealed a distinction both between different extracts of the same fungal species and between similar extracts of different species. The results obtained on antioxidative activities (LP inhibition and "scavenging" activity) indicate that MeOH extracts manifested a degree of activity higher than that of CHCl3 extracts with respect to antioxidative activity, the extracts can be ranged in the following declining order: Ganoderma lucidum, Ganoderma applanatum Meripilus giganteus, and Flammulina velutipes. The obtained results suggest that the analyzed fungi are of potential interest as sources of strong natural antioxidants in the food and cosmetics industries, whereas synthetic ones have proved to be carcinogenic. <br><br><b><font color="red">Detected autoplagiarism.

Abstract
Objective of our study was to use morphophysiological criteria in order to determine the sensitivity of male rat thyroid gland to an extremely low frequency electromagnetic field (ELF-EMF) influence and the ability of the gland to repair after period of exposure. Animals were exposed to 50Hz, 50-500 microT ELF-EMF for 3 months when a part of them (group I) were sacrificed, while the rest of animals were subjected to recovery evaluation of the gland and sacrificed after 1 (group II), 2 (group III) and 3 (group IV) weeks. Histological and stereological analyses were performed on paraffin and semifine thyroid gland sections. Serum T3 and T4 were also determined. Histological and stereological analyses showed that the volume density of follicular epithelium and thyroid activation index decreased, while the volume density of colloid and capillary network increased in group I, II and III. The values of all these parameters in group IV were similar to corresponding controls. Serum T3 and T4 concentrations were significantly lower in all exposed animals, except in group I. Results of this study demonstrate that after significant morphophysiological changes caused by ELF-EMF exposure thyroid gland recovered morphologically, but not physiologically, during the investigated repair period.

Abstract
The present study describes the antimicrobial activity and free radical scavenging capacity (RSC) of essential oils from Mentha aquatica L., Mentha longifolia L., and Mentha piperita L. The chemical profile of each essential oil was determined by GC-MS and TLC. All essential oils exhibited very strong antibacterial activity, in particularly against Esherichia coli strains. The most powerful was M. piperita essential oil, especially towards multiresistant strain of Shigella sonei and Micrococcus flavus ATTC 10,240. All tested oils showed significant fungistatic and fungicidal activity [expressed as minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) values, respectively], that were considerably higher than those of the commercial fungicide bifonazole. The essential oils of M. piperita and M. longifolia were found to be more active than the essential oil of M. aquatica. Especially low MIC (4 microL/mL) and MFC (4 microL/mL) were found with M. piperita oil against Trichophyton tonsurans and Candida albicans (both 8 microL/mL). The RSC was evaluated by measuring the scavenging activity of the essential oils on the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and OH radicals. All examined essential oils were able to reduce DPPH radicals into the neutral DPPH-H form, and this activity was dose-dependent. However, only the M. piperita oil reduced DPPH to 50 % (IC50 = 2.53 microg/mL). The M. piperita essential oil also exhibited the highest OH radical scavenging activity, reducing OH radical generation in the Fenton reaction by 24 % (pure oil). According to GC-MS and TLC (dot-blot techniques), the most powerful scavenging compounds were monoterpene ketones (menthone and isomenthone) in the essential oils of M. longifolia and M. piperita and 1,8-cineole in the oil of M. aquatica.

Abstract
The objective of this study was to examine the impact of low-frequency electromagnetic field on male rat thyroid gland of Mill Hill strain. Animals were exposed to 50 Hz frequency, of decaying intensity from 500 microT to 50 microT and 10 V/m field, beginning 24 hours after birth, 7 hours a day, 5 days a week during three months. Results of histological and stereological analysis showed increased volume density of thyroid follicles, decreased thickness of the follicular epithelium, intrafollicular colloid content in lumen, decreased thyroid activation index, increased volume density of parafollicular cells, decreased volume of interfollicular connective tissue and increased number of degranulated mast cells in exposed animals in regard to control animals. Radioimmunologic assays were used to examine thyroid hormone concentrations in the blood serum revealing decrease of the total T4 as well as of total T3 in animals exposed to electromagnetic field in regard to controls. The obtained results show that a three month-exposition of animals to low frequency electromagnetic field led to morphofunctional alterations of the thyroid gland that can be referred to as reduced activity of the gland.

Abstract
The current problems with decreasing fossile resources and increasing environmental pollution by petrochemical-based plastics have stimulated investigations to find biosynthetic materials which are also biodegradable. Bacterial reserve materials such as polyhydroxyalkanoates (PHA) have been discovered to possess thermoplastic properties and can be synthesized from renewable resources. Poly-beta-hydroxybutyric acid (PHB) is at present the most promising PHA; and BIOPOL, its copolymer with poly-beta-hydroxy-valerate (PHV), is already industrially produced (ICI, UK), and used as packaging material (WELLA, FRG). According to the literature, PHA degradation has so far mainly been observed in bacteria; only under certain environmental conditions has fungal degradation of PHAs been indicated. Since fungi constitute an important part of microbial populations participating in degradation processes, a simple screening method for fungal degradation of BIOPOL, a PHA-based plastic, was developed. Several media with about 150 fungal strains from different terrestrial environments and belonging to different systematic and ecological groups were used. PHA depolymerization was tested on three PHB-based media, each with 0.1% BIOPOL or PHB homopolymer causing turbidity of the medium. The media contained either a comparatively low or high content of organic carbon (beside PHA) or were based on mineral medium with PHA as the principal source of carbon. The degradation activity was detectable due to formation of a clear halo around the colony (Petri plates) or a clear zone under the colony (test tubes).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Acid and alkaline phosphatase activity were determined in a small pond over a period of 24 months (64 samples). Activity of each phosphatase enzyme was positively correlated with chlorophyll concentration, viable bacterial count, total phosphate concentration, inorganic phosphate concentration, and temperature. Multiple regression analysis was used to formulate equations that described phosphatase activity in terms of these physical, chemical, and biotic factors. Corrected coefficients of determination were calculated, and the highest values were obtained when all parameters were included in the equation (r (2)=0.776 and 0.659 for alkaline and acid phosphatase activity, respectively). However, there was little improvement in ther (2) value obtained when only chlorophyll was used in the equation (r (2)=0.654 and 0.624, respectively). Samples were then taken over a further 12 months (25 samples), and observed activity was compared with the activity predicted by application of the previously derived equations. For alkaline phosphatase, the best fit between observed and expected activity was seen with the equation containing all parameters, but for acid phosphatase the best fit was seen with the equation containing only chlorophyll and temperature as the determinants. In both cases there was a good fit between observed and expected data using the equation containing chlorophyll as the sole determinant. From this we have concluded that phytoplankton were the chief producers of phosphatase activity in this pond, although the influence of physical and chemical factors on enzyme activity could not be ignored.
