Atopic dermatitis is a common allergic skin disease in dogs. The aim of this study was to examine the possibility of a correlation between biophysical skin variables: skin hydration (SH), skin pH, and erythema intensity measured in 10 different body regions and both total Canine Atopic Dermatitis Extent and Severity Index (CADESI-03) and CADESI measured in a given region (CADESI L). The study was conducted using 33 dogs with atopic dermatitis. The assessment of the biophysical variables was done in 10 body regions: the lumbar region, right axillary fossa, right inguinal region, ventral abdominal region, right lateral thorax region, internal surface of the auricle, interdigital region of right forelimb, cheek, bridge of nose, and lateral site of antebrachum. Positive correlations were found between SH and CADESI L for the following regions: the inguinal region (r = 0.73) and the interdigital region (r = 0.82), as well as between total CADESI and SH on digital region (r = 0.52). Also, positive correlations were reported for skin pH and CADESI L in the lumbar region (r = 0.57), the right lateral thorax region (r = 0.40), and the lateral antebrachum (r = 0.35). Positive correlations were found in the interdigital region between erythema intensity and the total CADESI-03 (r = 0.60) as well as the CADESI L (r = 0.7). The results obtained suggest that it may be possible to use skin hydration, pH, and erythema intensity to assess the severity of skin lesion but positive correlation was only found in < 13.3% of possible correlations and usage of these measures in dogs is limited.  相似文献   

Modification of Chitin with Kraft Lignin and Development of New Biosorbents for Removal of Cadmium(II) and Nickel(II) Ions

Novel, functional materials based on chitin of marine origin and lignin were prepared. The synthesized materials were subjected to physicochemical, dispersive-morphological and electrokinetic analysis. The results confirm the effectiveness of the proposed method of synthesis of functional chitin/lignin materials. Mechanism of chitin modification by lignin is based on formation of hydrogen bonds between chitin and lignin. Additionally, the chitin/lignin materials were studied from the perspective of waste water treatment. The synthetic method presented in this work shows an attractive and facile route for producing low-cost chitin/lignin biosorbents with high efficiency of nickel and cadmium adsorption (88.0% and 98.4%, respectively). The discovery of this facile method of synthesis of functional chitin/lignin materials will also have a significant impact on the problematic issue of the utilization of chitinous waste from the seafood industry, as well as lignin by-products from the pulp and paper industry.  相似文献   

Ion Equilibrium in the Soil Solution in Long-term Fertilization Experiment on Sandy Soil     

Jan Łabętowicz  Beata Rutkowska  Wiesław Szulc 《Archives of Agronomy and Soil Science》2013,59(5):445-449

In the conditions of long-term experiment carried out in the experimental field of Warsaw Agricultural University - SGGW at _ yczyn, ion concentration in the soil solution were examined as well as the relationships shaped between ions in the soil solution due to long-term diversified mineral and organic fertilization. Soil solution was obtained by the vacuum method and the concentration of particular ions in the soil solution was determined by the ICP method. Mineral and organic fertilization and liming significantly affected chemical composition of the soil solution and the relationships between particular ions in the soil solution. The lowest concentration of ions in the soil solution was observed in the control plots (not fertilized). Mineral and organic fertilization as well as liming caused the increase of ion concentration in the soil solution. In the plots with mineral fertilization alone K + and NH + 4 ions predominated in the cation structure in the soil solution. In the case of liming the share of Ca 2+ ions increased. Independently from the system of fertilization used, CI m and HCO m 3 ions predominated in the anion structure. The application of organic fertilization affected to the highest degree the concentration of aluminium ion in the soil solution significantly limiting the share of this ion in the cation structure.  相似文献   

Analysis of microtubule and microfilament distribution in Pinus sylvestris roots following infection by Heterobasidion species

Cytoskeletal dynamics play a crucial role in pathogen recognition and cell defence during the initial interactions between an invader and plant host. The aim of the work reported here was to characterize how Heterobasidion annosum s.s., Heterobasidion parviporum, and Heterobasidion abietinum affect the microtubules and microfilaments of Pinus sylvestris root cells 12‐, 24‐, 48‐, and 96‐h post‐inoculation. Inoculation of P. sylvestris with H. parviporum or H. abietinum, which have a lower specificity for P. sylvestris than H. annosum s.s, resulted in greater reorganization of host microtubules during the early stages of interaction than inoculation with the more specific H. annosum s.s. In some infected cells, spots of actin aggregates were observed. Disruption of cytoskeletal components by the application of specific cytoskeletal inhibitors facilitated the entry of the H. parviporum and H. abietinum into roots. These results suggest that the P. sylvestris cytoskeleton plays a role in the host response in the initial stages of the host–pathogen interaction.  相似文献   

Effects of brewer’s yeast extract on growth performance and health of juvenile pikeperch Sander lucioperca (L.)     

S. JARMOŁOWICZ  Z. ZAKĘŚ  A. SIWICKI  A. KOWALSKA  M. HOPKO  E. GŁĄBSKI  K. DEMSKA‐ZAKĘŚ  K. PARTYKA 《Aquaculture Nutrition》2012,18(4):457-464

Juvenile European pikeperch, Sander lucioperca, were fed commercial feed (group C) or experimental feed supplemented with NuPro^® nucleotide‐rich Saccharomyces cerevisiae yeast protein (extract obtained through a cell wall removal process) in doses of 20, 40 or 60 g kg^?1 feed (groups N2, N4, N6) for 8 weeks. Growth, non‐specific immunity parameters, histological structure of the liver and intestine, proximate whole‐body composition and blood biochemical parameters were assayed. It was noted that brewer’s yeast extract has immunomodulatory proprieties. NuPro^® in doses of 40 and 60 g kg^?1 feed strongly stimulated non‐specific (innate) cellular and humoral immunity in pikeperch. The experimental feed did not have a significant impact on pikeperch growth (P > 0.05). The proximate composition of the fish bodies and the hepatosomatic and viscerosomatic (VSI) indices were also not affected, which indicated that the tested diets had no negative impact on the metabolism or deposition of nutrients in fish tissues. The lower levels of transaminases AST and ALT, which were noted in the groups with the two highest doses of NuPro^® (P < 0.05), might indicate improved liver function. It was also demonstrated that the brewer’s yeast extract stimulates the absorption activity of intestinal epithelial cells.  相似文献

The tardigrade fauna of Tunisia,with an integrative description of Bryodelphax maculatus sp. nov. (Heterotardigrada: Echiniscidae)     

Piotr Gąsiorek  Daniel Stec  Witold Morek  Jamila Marnissi  Łukasz Michalczyk 《African Zoology》2017,52(2):77-89

The current knowledge of the diversity and distribution of tardigrade species in northern Africa is scarce and far from satisfactory. In this paper we review old and provide new faunistic records for various regions of Tunisia. Among the newly recorded taxa, we found a new heterotardigrade Bryodelphax maculatus sp. nov. The new species belongs to the weglarskae group, characterised by the presence of ventral plates, but differs from its congeners by a different arrangement of ventral plates and by conspicuous groups of cuticular tubercles on the ventral cuticle. The analysis of larval, juvenile and mature instars of the new species revealed, for the first time in heterotardigrades, ontogenetic variability in the development of ventral armature.

Sulfachlorpyrazine residues depletion in turkey edible tissues     

B.I. ŁEBKOWSKA‐WIERUSZEWSKA  C. J. KOWALSKI 《Journal of veterinary pharmacology and therapeutics》2010,33(4):389-395

?ebkowska‐Wieruszewska, B.I., Kowalski, C.J. Sulfachlorpyrazine residues depletion in turkey edible tissues. J. vet. Pharmacol. Therap. doi: 10.1111/j.1365‐2885.2009.01147.x. Sulfachlorpyrazine (SCP) is currently used to treat coccidian infections in turkeys; however, there is no information available about the withdrawal period necessary for the turkey to be safe for human consumption. A high performance liquid chromatography method with ultraviolet‐visible light detection was adapted and validated for the determination of SCP in turkey tissues. The procedure is based on isolation of the (SCP sodium) compound from edible turkey tissues (muscles, liver, kidneys, and fat with skin) with satisfactory recovery (72.80 ± 1.40) and specificity. The residue depletion of SCP in turkeys was conducted after a dose of 50 mg/kg body weight/day had been administrated orally for 3 days. After treatment has been discontinued residue concentrations were detected in tissues on the 7th day. The highest SCP concentrations were measured in muscles. Based on the results presented in this study, it could be assumed that a withdrawal period of 21 days, before medicated turkeys could be slaughtered, would be sufficient to ensure consumer safety.  相似文献   

Use of serial pig body weights for genetic evaluation of daily gain     

B. Zumbach  I. Misztal  C.Y. Chen  S. Tsuruta  M. Łukaszewicz  W.O. Herring  M. Culbertson 《Zeitschrift für Tierzüchtung und Züchtungsbiologie》2010,127(2):93-99

This study examined the utility of serial weights from FIRE (Feed Intake Recording Equipment, Osborne Industries, Inc., Osborne, KS, USA) stations for an analysis of daily gain. Data included 884 132 body weight records from 3888 purebred Duroc pigs. Pigs entered the feeder station at age 77–149 days and left at age 95–184 days. A substantial number of records were abnormal, showing body weight close to 0 or up to twice the average weight. Plots of body weights for some animals indicated two parallel growth curves. Initial editing used a robust regression, which was a two‐step procedure. In the first step, a quadratic growth curve was estimated assuming small or 0 weights for points far away from the curve; the process is iterative. In the second step, weights more than 1.5 SD from the estimated growth curve were treated as outliers. The retained body weight records (607 597) were averaged to create average daily weight (170 443) and then used to calculate daily gains (152 636). Additional editing steps included retaining only animals with ≥50 body weight records and SD of the daily gain ≤2 kg, followed by removing records outside 3 SD from the mean for given age, across all the animals – the resulting data set included 69 068 records of daily gain from 1921 animals. Daily gain based on daily, weekly and bi‐weekly intervals was analysed using repeatability models. Heritability estimates were 0.04, 6 and 9%, respectively. The last two estimates correspond to heritability of 28% for a 12 week interval. For daily gain averaged weekly, the estimate of heritability obtained with a random regression model varied from 0.07 to 0.10. After extensive editing, body weight records from automatic feeding stations are useful for genetic analyses of daily gain from weekly or bi‐weekly but not daily intervals.  相似文献   

Underwater evaluation of habitat partitioning in a European river between a non‐native invader,the racer goby and a threatened native fish,the European bullhead          下载免费PDF全文

Tomasz Kakareko  Jarosław Kobak  Małgorzata Poznańska  Łukasz Jermacz  Gordon H. Copp 《Ecology of Freshwater Fish》2016,25(1):60-71

We conducted underwater surveys using SCUBA gear to examine habitat and microhabitat competition between the Ponto‐Caspian racer goby Babka gymnotrachelus and native European bullhead Cottus gobio to assess the potential for competitive displacement of the native species by the invading species. In summer, 88 surveys were made in a tributary of the River Vistula within defined benthic areas across the entire width of the river bed. The occurrence of fish by total length class (small: <6 cm; large: >6 cm) and environmental conditions (depth, water velocity, substratum type, plant cover, shelter type) was recorded. We found a substantial separation between the species and size classes in relation to substratum, shelter type and water velocity. European bullheads were limited to lotic areas with stony bottoms, whereas racer gobies also occupied lentic areas over sand or mud. European bullheads usually took refuge under stones in contrast to a wider range of shelters used by racer goby, including tree roots and rubbish. In general, the breadth of habitat used by the racer goby was wider than that of the European bullhead, although habitat overlap between the species was not statistically significant except for the type of shelter occupied by small fish, selecting smaller stones. An inverse relationship was observed between small European bullheads and all racer gobies in areas where they co‐occurred, suggesting that invader may be having an adverse effect on the distribution and habitat use of small native bullheads, particularly in areas of moderate water velocities over small stones and gravel.  相似文献
