Characterisation of black locust isolates of <Emphasis Type="Italic">Peanut stunt virus</Emphasis> (PSV) from the Pannon ecoregion show the frequent occurrence of the fourth taxonomic PSV subgroup

Biological and molecular characterisation of ten Peanut stunt virus (PSV) isolates from Robinia pseudoacacia was carried out. The host range of these isolates was similar to that of the previously described PSV strains in most cases, but on Pisum sativum and Lens culinaris latent infection was induced. Variability in systemic symptoms was observed only on Nicotiana glutinosa. The partial RNA3 sequences were determined, including the carboxyl terminal region of the movement protein gene, the intergenic region, the entire coat protein gene and the 3′ untranslated region. Nucleotide sequence comparison of the coat protein genes showed 77.6–84.2% identity with most of the known PSV strains and 96.3–98.0% identity with PSV-Rp the typical member of subgroup IV. Phylogenetic analysis indicated the presence of the ancient homologous recombination in all of the examined black locust isolates and all the isolates were members of the fourth PSV subgroup. These results showed that the isolates of the fourth subgroup are widely distributed in black locust in this region.     

Mouse barley awn (Hordeum murinum) migration induced cystolithiasis in 2 male dogs

Two male dogs were presented with cystic uroliths composed of magnesium ammonium phosphate (struvite). Each had an atypical nidus, a mouse barley awn (Hordeum murinum). To our knowledge, this is the first report of grass awns located in the bladder lumen of dogs. The composition of uroliths and the pathophysiology of grass awn migration to the urinary bladder are discussed.     

Biological value of proteins in PSE meat

A bioassay was made on male SPS Norway rats of the Wistar strain to study the biological value of PSE meat protein in a ten-day trial. Pork meat of m. longissimus dorsi was denoted as PSE meat on the basis of low pH1 values, colour and water content. Raw meat and thermally treated meat was used for feeding (thermal treatment: 75 degrees C for 60 min). The biological value of altered meat (thermally treated products), expressed on the basis of PER, NPU and LPU values, draws attention to the difference from the biological value of normal meat. However, no such a difference was recorded in PSE meat administered in raw condition.     

Experimental results and clinical impact of using autologous rectus fascia sheath for vascular replacement

Vascular complications are major causes of graft failure in liver transplantation. The use of different vascular grafts is common but the results are controversial. The aim of this study was to create an 'ideal' arterial interponate for vascular replacements in the clinical field. An autologous, tubular graft prepared from the posterior rectus fascia sheath was used for iliac artery replacement in dogs for 1, 3, 6 and 12 months. Forty-one grafts were implanted and immunosuppression was used in separate groups. The patency rate was followed by Doppler ultrasound. Thirty-seven grafts remained patent, 2 cases with thrombosis and 2 cases with stenosis occurred. There was no evidence of necrosis or aneurysmatic formation. The histological analysis included conventional light microscopic and immunohistochemical examinations for CD34 and factor VIII. The explanted grafts showed signs of arterialisation, appearance of elastin fibres, and smooth muscle cells after 6 months. Electron microscopy showed intact mitochondrial structures without signs of hypoxia. In conclusion, the autologous graft presents acceptable long-term patency rate. It is easy to handle and the concept of beneficial presence of the anti-clot mesothelium until endothelialisation seems to work. The first clinical use was already reported by our group with more than 2 years survival.     

Electrochemical Properties and Biochemical Composition of <Emphasis Type="Italic">Cv. </Emphasis>Shiraz Wine Grape (<Emphasis Type="Italic">V. vinifera</Emphasis> L.) Depending on Various Dose and Application Time of Foliar Microbial Fertilizer Treatments

Utilization from bio fertilization is well known a considerable tool to improve the yield and fruit quality of various crop fruits through the increasing emphasis on maintain of soil health, minimize environmental pollution and decrease the use of chemical fertilization. In this study, in order to improve wine grape quality features of cv. Shiraz, four different doses of foliar microbial fertilizer, including 0, 1000, 2000 and 3000?ppm were applied at two different terms as Term I (mostly; pre-bloom applications) and Term II (mostly; post-bloom applications). However, there were no influences of application terms of foliar microbial fertilizer treatments; treatment doses had considerable effects on yield and quality parameters. The lowest p-values, meaning the highest berry quality, from doses of foliar microbial fertilizer were obtained from 2000?ppm (105.08?μW), 1000?ppm (110.40?μW), 3000?ppm (112.97?μW) and 0?ppm (119.58?μW). Comparing the applications of foliar microbial fertilizer, it was observed that doses of 2000?ppm (3155.56?mg/kg), 1000?ppm (3000.92?mg/kg) and 3000?ppm (2530.19?mg/kg) exhibited higher total phenolic compounds content when compared with 0?ppm treatment (2206.97?mg/kg). Berries from grapevines applied with the doses of 2000, 1000 and 3000?ppm foliar microbial fertilizer respectively shown higher total anthocyanin content such as 1230.19, 1160.85 and 865.86?mg/kg compared to 0?ppm (637.37?mg/kg). As a result, research the findings indicated that 2000 and 1000?ppm doses of foliar microbial fertilizer were obviously effective on wine grape quality features of cv. Shiraz in terms of electrochemical property, total phenolic compounds content and total anthocyanin content.     

Enhancing Skin Color and Phenolic Compounds of Cv. Red Globe Table Grape (<Emphasis Type="Italic">V. Vinifera</Emphasis> L.) Utilizing of Different Preharvest Treatments

Foliar sprayings of grapevines with different plant growth regulators or chemicals were evaluated for determining grape skin color and phenolic compounds content and enhancing table grape quality characteristics of cv. Red Globe in this study. Grape skin color is one of the most important quality factors for table grapes. Sometimes, it can be viewed difficulties in skin coloration of some red table grape cultivars grown in various grape growing regions of the world and poor skin coloration of red table grapes is a frequent trouble that reduces production efficiency. Despite the fact that it is utilized from some canopy management practices; plant growth regulators, chemicals with plant hormones and hormone-like compounds as active ingredients can be recently used for improving anthocyanin accumulation in growing of some table grape cultivars. In current study, nine different preharvest treatments were used for improving quality parameters of cv. Red Globe, including 1?Control (C), 2–300?mg/L Abscisic acid (ABA), 3–300?mg/L Ethephon (Eth), 4–30% Ethanol (EtOH), 5–300?mg/L ABA + 300?mg/L Eth, 6–300?mg/L ABA + 30% EtOH, 7–300?mg/L Eth + 30% EtOH, 8–300?mg/L ABA + 300?mg/L Eth + 30% EtOH and 9?Cluster tip cutting (CTC). Although the best results from total phenolic compounds content and total anthocyanin content of cv. Red Globe were obtained in CTC treatment in all preharvest treatments, Eth+ETOH treatment especially gave rise to the best results among the preharvest chemical treatments.
