Background and purpose: The aim of this review is to present current knowledge on the occurrence of a little-known gnaphosid species Gnaphosa modestior Kulczynski, 1897. Early it was mentioned as G. alpica species in Middle Europe. In this study, we reported the new occurrence of this species in Hungary and we examined of the effect of shrub control and mowing on this species abundance. Materials and methods: Our arachnological research was conducted in the Matra Mountains, the highest range of volcanic massin northern Hungary, between 2007 and 2016. Result and conclusion: We recorded 13 specimens from five habitats of the southern part of the Matra Mountains. This species can be found mainly in untreated shrubby habitats from April to June. In general, it can say that G. modestior is a stenochronous spider species which lives in habitats not influenced by human activities in the Matra Mountains. However, this attributes of species differ in some European countries.

Scope: We investigated the potential beneficial effect of Apocynin (APO) on motor and cognitive functions in experimental Alzheimer’s disease (AD). Materials and Methods: Experimental AD was induced in rats by intraventricular streptozotocin (STZ) injection. Sham group received artificial cerebrospinal fluid (CSF). Both groups were randomly divided into two subgroups. One of the subgroups received intraperitoneal APO for while the other had normal saline (NS). The animals were evaluated with rotarod, accelerod and Water-Maze tests before and after the treatment. Additionally, biochemical markers of oxidative stress such as malondialdehyde (MDA) and reduced glutathione (GSH) were analyzed from brain specimens. Standard histological evaluation and transmission electron microscopy (TEM) were used to evaluate the neural damage. Results: The difference between STZ+NS in comparison with CSF+NS, CSF+APO and STZ+APO were statistically significant on 30 and 40 rpm on rotarod test. GSH levels, accelerod and Water-Maze test results were not statistically significant between subgroups. However, MDA differences between STZ+NS in comparison with CSF+NS, CSF+APO and STZ+APO were statistically significant. Hemotoxilene eozine staining and TEM results showed apocynins protective effect. Conclusion: These results indicate that APO can provide neuro-protective effect for motor but not for cognitive performance in experimental AD. Keywords: Alzheimer’s disease, Streptozotocin, Apocynin, Rotarod test, Accelerod test, Water-Maze test

Background. We have studied human life expectancy in Croatia. Materials and Methods. Local daily papers reported obituitairies for 447 men and 366 who died in a month period. The data were analyzed with the median derivative power function model. Results. The median age of death was 76 and 81 years for men and women, respectively. Cummulative mortality increases at a constant rate after the age 60 y and 65 y for men and women, respectively (r2 = 0.99 and 0.98). Conclusions. Individual life span is a stochastic (random) biological event within the deterministic frame of cumulative mortality.

Purpose:The purpose of investigations was to evaluate the effect of site conditions on the variability of traits of Valeriana officinalis L. var. officinalis. Materials and methods:The studies were carried out in the years 2014-2016 in two study areas consisting of patches of Filipendulion ulmariae with a substantial share of low- and medium-growing perennials (Patch I), tall-growing perennials (Patch II), as well as tall-growing perennials and shrubs (Patch III). Results:Similar tendencies were observed in both study areas. The plant and cryptogam cover showed neither spatial nor temporal variability, while the height of neighbouring plants, as well as the pH and moisture of soil, augmented in subsequent patches. The lowest abundance of subpopulation Valeriana officinalis was noted in Patch III. During the study period seedlings and juveniles were not found in any of the patches, whilst the share of vegetative genets diminished gradually at the cost of generative individuals and ramet clusters. The majority of individual traits (e.g. number of ramets, radical leaves and flowers, number and height of flowering stems) augmented in successive patches, while the number of radical leaves in generative individuals and ramet clusters, as well as the height of flowering stems and number of flowers, additionally augmented in consecutive years. Conclusions: The considerable share of vegetative individuals in sites dominated by low-statured plants contributes to rejuvenation of subpopulations. The clonal growth might protect all subpopulations from regression. The substantial production and dimensions of flowering stems in vicinity of tall-growing perennials enlarges the chances for successful pollination and seed dispersal.

Background and purpose: Amylases are commercially important enzymes with various biotechnological, clinical and medical applications. This study aimed at scaling up α-amylase production elicited by rice husk in stirred-fermenter using Bacillus lichneniformis-AZ2 isolated from Qinarje Hot Spring. Materials and methods: Effect of temperature, aeration rate and agitation speed on bacterial growth and ɑ-amylase production were investigated under batch fermentation process in a 3-Lit stirred-fermenter. OFAT method was followed to select optimum level of each parameter. Other factors were set upon the results of previous experiments carried out in shake-flask scale. Results: Maximum α-amylase production of 17.66 ± 0.87 U/mL (2.1 folds more than shake-flask cultures) was achieved in stirred-fermenter with optimized agitation speed of 100 rpm and 1 vvm aeration rate at 37oC after 60 h of incubation. This time was shorter than the corresponding fermentation time obtained from shake-flask experiments by half. A comparison of kinetic parameters of fermentation in stirred-fermenter and shake-flask cultures revealed that B. licheniformis-AZ2 was more active to synthesize ɑ-amylase in fermenter. In shaken cultures Qx, Qp, Yp/x, µmax, qp and td, were 0.27 (g/L/h), 228.6 (U/L/h), 13.64 (U/g), 0.055 (h-1), 0.76 (U/g/h) and 12.48 h, whereas in stirred-fermenter the above values were 0.40 (g/L/h), 723.1 (U/L/h), 45.17 (U/g), 0.120 (h-1), 5.42 (U/g/h) and 5.78 h, respectively. Conclusions: SmF in stirred-fermenter is a potential strategy for ɑ-amylase production. Although for commercialization further studies are needed in pilot-scale. Rice husk as a low-cost agro-waste is preferable to use as the carbon and energy sources, which provides a great ɑ-amylase elicitation.

Background and Purpose: Poor cod, Trisopterus minutus (Linnaeus, 1758) is a gadoid fish, which inhabits the Mediterranean and eastern Atlantic. The aim of present work was to investigate the morphological properties of poor cod in the eastern central Adriatic Sea by analyzing classical morphometric and meristic characteristics, and thereby investigating: a) whether there are morphological differences between males and females; b) the existence of possible homogenous or heterogeneous stock morphology; and c) the changes in morphometric characteristics with increase in body length.Material and methods: Samples of 410 poor cod specimens (209 females, 201 males) were collected by bottom-trawl between 2014 and 2016 from five localities in the eastern central Adriatic Sea. In order to analyze biometry of the species; fifteen morphometric and eight meristic characteristics were measured.Results and Conclusions: Total length of all specimens ranged from 8.8 to 27.1 cm. Morphological differences between males and females was not marked. Biometric analysis of the morphometric and meristic characteristics indicated a homogenous morphology stock of Trisopterus minutus in the Adriatic Sea. Changes in some morphometric characteristics obtained in conjunction with an increase in body length showed that smaller specimens have a longer head, eye diameter, ventral fins and second anal fins than adult specimens. The negative correlation recorded for the maximum and minimum body depth indicated that the body elongated with poor cod growth. Comparison of the meristic characteristics that were published earlier show some differences between the poor cod populations inhabiting the Adriatic, Black Sea and eastern Atlantic.

Background and purpose: Chronic renal failure is a syndrome characterized by progressive and irreversible loss of nephrons depending on various diseases. Especially infection such as HBV and HCV is among the major causes of mortality and morbidity in hemodialysis patients. In the present study we aimed to determine the levels of 3-nitrotyrosine (3-NT), TNF-like weak inducer of apoptosis (TWEAK) and heat shock protein (HSP70) in chronic renal failure patients diagnosed with HBV, HCV and non-hepatitis undergoing hemodialysis treatment. Materials and methods: Samples of 235-patients receiving hemodialysis treatment and 25-healthy individuals were included in the study. Firstly, HBV and HCV positivity were diagnosed by serological Enzyme-Linked ImmunuSorbent Assay (ELISA) method. Then, 3-NT levels were determined using High-Performance Liquid Chromatography (HPLC), while TWEAK and HSP70 were determined using high sensitivity ELISA. The numbers of patients used in the studies were determined according to statistical power analysis.Results: The values of 3-NT and HSP70 were found to be significantly higher non-hepatitis patients, HBV and HCV patients receiving hemodialysis treatment to compared with the control group (p‹0.05). Concentration of TWEAK in non-hepatitis and HBV patients receiving hemodialysis therapy was found to be significantly higher to compared with the control group (p‹0.05). However, unlike the other two groups, an increase in the TWEAK of HCV patients on post-dialysis was determined.Conclusions: To prevent the increase of inflammation and oxidative stress in hemodialysis patients or to keep it under control, investigating certain parameters such as TWEAK, 3-NT and HSP70 from time to time is of great importance in terms of minimizing the level of risk for many diseases such as cardiovascular diseases. Infection also increases the burden on oxidative stress and immunity system in these patients.

Background and purpose Calosoma auropunctatum (Herbst) is the species with no confirmed records in the last 150 years in Latvian fauna. Until now the species was considered possible extinct in this area. The species was confirmed for Latvia in 2014, during the research project devoted to biodiversity monitoring in various agrocenoses with different management systems. The paper is aimed to clarify habitat peculiarities of the species in Latvian fauna and discuss the possibilities of widest distribution of this species in Easter Baltic region.Materials and methods The study site is located in the eastern part of Latvia, from May 2014 to August 2015. The ground beetles were collected using pitfall traps, installed in 2 linear transects located at field margin and in the field central part, more than 100 m. far away from the field border.Results One male and three females were caught by pitfall traps during vegetation period in cource of 2014-2015 years. Calosoma specimens deposited in coleopterological collections in Latvia were reviewed. Previous record of this species in Latvia based on specimen deposited in Latvian Museum of Natural History is disproved. In addition the paper presents information on the geographical distribution and biology of the species.Conclusions The first proven findings of C. auropunctatum in Latvia was presented during two field season’s, that suggest a presumption of occurring of small, local population of this species in territory of Latvia.

Background and purpose: Hyperosmotic solutions of calcium chloride and calcium bromide, extensively used in the oil industry, can be a source of aquatic pollution.Materials and methods: In the present study, we investigated whether the freshwater snail Planorbarius corneus L., previously chronically exposed to toxic concentrations of these chemicals, can recover fecundity and growth in clean water. We also examined if a higher tolerance could be induced in F1 offspring after parental and developmental chronic exposure to the chemicals.Results: The fitness-recovery study showed a high compensatory potential of the snails to recover fitness through increased reproduction and growth. In the tolerance study, we observed increased tolerance in F1 offspring in hyperosmotic solutions of calcium chloride. However, there was no significant improvement of reproduction performance in bromide-containing solutions.Conclusions: Increased tolerance was associated with a redirection of resources from growth to maintenance and survival.
