Opis:: Infectious bronchitis (IB) is an important disease that causes severe economic loses in the poultry industry worldwide. Furthermore, the spread of new variants poses a challenge for diagnosis and control of the disease. This study investigated the situation of infectious bronchitis virus (IBV), specifically the Israel variant-2 (IS var-2) also known as GI-23 genotype, in Turkey. Between 2014 and 2019, 214 flocks vaccinated against H120 from Marmara, Western Black Sea, and Inner Anatolia were examined, with 127 (59.3%) flocks testing positive for IBV, of which 92 (72.4%) were positive for IS var-2. Of the latter samples, 60 were randomly selected and subjected to full S1 gene sequencing. The analysis indicated that the field strain in Turkey was located on the same branch as the GI-23 genotype, which is one of the most frequently observed wild-type cluster found in the Middle East. The DNA similarities between the GI-23 isolates from 2014 to 2019 were 99%. In conclusion, the IS var-2 genotype has been circulating in broiler flocks in Turkey. It is recommended that establishing the vaccine strategy it should be considered the current circulating strains for the prevention and control of the disease among poultry.

Opis:: Hyssopus officinalis L. is a medicinal plant containing valuable phytochemicals and is used extensively in the pharmaceutical industry. As this plant naturally contains low levels of these metabolites, plant cell and tissue culture technologies are used to produce them in large volumes. The present study aimed first to evaluate the effects of different types of cytokinins, including benzyl adenine (BA), kinetin (KIN), and thidiazuron (TDZ), at 1 ppm concentration in the culture medium on growth parameters and production of secondary metabolites and photosynthetic pigments in organ culture of H. officinalis; in the second step, the study investigated the effect of different concentrations (0, 0.2, 1, 1.5, and 2 ppm) of the most effective type of cytokinin. The results showed that TDZ was the optimal type of growth regulator compared to BA and KIN as it showed a positive influence on the studied traits; furthermore, its highest concentration of 2 ppm in culture medium was determined to be the best one that enabled the highest production of secondary metabolites and photosynthetic pigments. We conclude that the presence of growth regulators can strongly influence the growth and development of plants in tissue culture conditions.

Opis:: Kikuchi-Fujimoto disease (KFD) is an infrequent benign self-limiting disease predominantly affecting young Asian women and has an excellent prognosis. Diagnosis of KFD is confirmed by characteristic immunohistology of lymph node biopsy revealing histiocytic necrotizing lymphadenitis with abundant CD 68+ plasmacytoid monocytes in the paracortex and karyorrhectic debris. SLE, in particular, has been reported to precede, occur simultaneously, or appear after KFD. Treatment modalities and clinical outcomes of both KFD and SLE are vastly different. Hence, it is imperative to make timely correct diagnoses of SLE and treat early to avoid multi-organ failure and potentially fatal outcomes. The case report is presented of a challenging case of a 26-year-old Asian male who was initially diagnosed with KFD, and subsequently met the diagnostic criteria for SLE. He was treated for SLE for 6 months and showed dramatic improvement symptomatically without any further recurrence.

Opis:: Subject and purpose of work: This research was conducted to measure the influence of the Suramadu Bridge on the reduction of rural poverty and to determine the impact of production factors such as physical capital, natural capital, human capital and financial capital on poverty before and after the Suramadu Bridge began operating in Kabupaten Bangkalan. Materials and methods: This study adapted the model used by Nashwari et al (2017) which was analysed applying Ordinary Least Square (OLS). The data from Village Potential 2007 and 2017 was used in the research. Results: Many production factors in the village did not have a significant effect on the poverty reduction before the Suramadu Bridge began operating. After the Suramadu Bridge opened, it has had a significant negative impact on poverty. The number of farmers, rice fields, non-agricultural activities, superior products, skills facilities and credit facilities has a significant positive effect on the reduction of the poverty level. Conclusions: The existence of the Suramadu Bridge has increased the influence of production factors in the villages on the poverty reduction in Kabupaten Bangkalan.

Opis:: In recent years, safety of a ships has become one important issues needed to solved as soon as possible in ship navigation. Optimal weather routing is one of best solution for ensuring safe operation of a ship with a with short passage time or minimum energy to avoid a certain excessive motion. This paper introduced the development of solution for safety and optimal weather routing a ship considering seakeeping performance based on model test result. This study introduced how to apply A* algorithm based on result of the seakeeping model test for determining the optimal ship routes. Seakeeping model test of 8600 TEU container ship was carried out in Changwon National University's seakeeping basin and its RAOs at various frequencies were used to predict the RMS motion values in irregular waves. The specially modelled path-cost function and the safety constraints were proposed for finding the optimal path of the ship. The comparison of ship performances estimated by great circle’s path and estimated optimal route during the voyage of the ship was investigated.

Opis:: There is an increasing consensus that diversifying into the cultivation of ‘Neglected and Underutilized Species’ (NUS), in addition to growing conventional crops, offers a plethora of livelihood-enhancing benefi ts to small-scale agricultural households. Therefore this study examined the factors that influence small-scale farmers’ diversifi cation into the cultivation of the cashew nut plant (Anarcadium occidentale, Moringa oleifera and Jatropha curcas) in the guinea savannah region of Nigeria. We employed farm household-level survey data of the phenomenon in Kwara State. The data were analyzed using the Simson Index of Diversity (SID) and Tobit censored regression. Findings indicate that respondents diversified most into the cultivation of cashews (70.9%), followed by moringa (38.4%), and jatropha (11.3%). The extent of diversifi cation was positively infl uenced by the farm size (p < 0.01), household head’s education level (p < 0.01), membership in a cooperative (p < 0.01), and farm income (p < 0.1). It was negatively infl uenced by the land tenure system practiced (p < 0.05). Findings imply, inter alia, that small-scale farmers may avoid diversifi cation into these crops if they have a limited access to cultivated land. This study therefore advocates ensuring equitable access to farmland through a structural and legislative land tenure reform policy.
Coraz powszechniej uznaje się, że poszerzanie konwencjonalnych upraw o gatunki marginalne i niedoceniane (Neglected and Underutilized Species, NUS) zapewnia małym gospodarstwom rolnym wiele korzyści, uzupełniając źródła utrzymania. W niniejszym artykule przeanalizowano czynniki, które wpływają na poszerzanie upraw przez właścicieli małych gospodarstw rolnych o nanercz zachodni (Anarcadium occidentale), moringę olejodajną (Moringa oleifera) oraz jatrofę przeczyszczającą (Jatropha curcas) w regionie Nigerian Guinea Savannah. Na potrzeby badania wykorzystano dane z ankiety przeprowadzonej w gospodarstwach rolnych stanu Kwara. Dane poddano analizie za pomocą wskaźnika różnorodności Simpsona (Simpson Index of Diversity, SID) oraz modelu tobitowego regresji cenzurowanej. Wyniki wskazują, że respondenci najczęściej poszerzali uprawy o nanercz (70,9%), a dopiero w dalszej kolejności o moringę (38,4%) i jatrofę (11,3%). Na stopień różnorodności upraw pozytywnie wpływały: wielkość gospodarstwa (p < 0,01), wykształcenie głowy rodziny (p < 0,01), członkostwo w spółdzielni (p < 0,01) oraz dochód gospodarstwa (p < 0,1), natomiast negatywny wpływ miał typ własności ziemi (p < 0,05). Wyniki wskazują, że właściciele małych gospodarstw rolnych mogą unikać poszerzania upraw o wymienione gatunki, jeśli mają ograniczony dostęp do uprawianej ziemi. Autorzy opowiadają się za zapewnieniem sprawiedliwego dostępu do ziemi przez przeprowadzenie prawnych oraz strukturalnych reform zasad najmu ziemi na omawianym obszarze.

Opis:: Gram-negative bacteria isolated from the abattoir effluent on surface water of River Katsinaala in rainy and dry seasons were Escherichia coli; Klebsiella spp; Proteus vulgaris; Salmonella typhi and Gram-positive bacterium isolated was Streptococcus faecalis. In rainy season, the lowest mean bacterial count was from E.coli (0.0067+0.031 CFU/ml) and highest mean bacterial count from Salmonella typhi (0.0262+0.0079 CFU/ml). In the dry season, lowest mean bacterial count was from Proteus vulgaris (0.0081+ 0.0047 CFU/ml) and the highest from Streptococcus faecalis (0.0097+ 0.05 CFU/ml). The presence of Escherichia coli indicates possible faecal contamination. The results revealed that bacterial load was within the accepted maximum limit by WHO (2004); nevertheless, the disease causing bacteria pose threat to human health when water from the river is consumed without treatment.

Opis:: Abamectin (Avermectin B1a), is a natural fermentation product derived from the soil bacterium Streptomyces avermitilis. Abamectin (Avermectin B1a) is widely used as an insecticide, acaricide, and anthelmintic. The present study assessed the effects of repeated subacute and subchronic exposure to the commercial formulation of abamectin (Vertemic, 1.8% EC) in albino male rats. The toxic effects of abamectin were studied. The various biochemical parameters and histopathological changes were noted. A stomach tube was used to orally administer sublethal doses of abamectin suspended in corn oil to the rats. The animals were divided into four groups. Rats of the group T1 were orally administered a sublethal dose of 30 mg/kg body weight (b.wt.) (1/10 LD50) three times a week for 30 days and the animals in group T2 were exposed to 10 mg/kg b.wt. (1/30 LD50) for 210 days, once a week. Two control groups (C1 and C2) were used in parallel studies, where animals were administered a corn oil vehicle. At the end of the study period, blood samples were collected from all groups to measure plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST) activities, and the levels of creatinine and urea. Also, total protein and RNA contents were determined in the liver and kidney tissues. Changes in biochemical parameters were more intense in male rats from group T2 than those reported in group T1. The levels of ALT, AST, urea and creatinine were significantly elevated in rats from group T2 when compared to the control. In group T2, a significant decrease in the levels of total protein and RNA in both the liver and kidneys was observed. Fertility was also significantly reduced in male rats ingesting abamectin in group T2. The number of offspring was significantly reduced. Histopathological changes were more intense in male rats from group T2 than those from group T1. In conclusion, the results of this study demonstrate that subchronic oral administration of abamectin altered some biochemical parameters which correlated with histopathological changes.

Opis:: Flora identified within a region plays an important role in maintaining national natural reserves. Iran is one of the most important centers of plant diversity in the Old World (22% endemic species of 8000 plant species). Dehdez burned forest area is located in the southeastern Khuzestan province. The field data were obtained from 115 sample plots in a systematic random grid (20 m × 20 m). The attributes such as tree and shrub species type, the number of species and canopy coverage were recorded. Within each sample plot small and large crown diameters were measured. In order to record herbaceous species, the Whitaker’s snail plot method was applied (100 m² minimum plot area). In this study, 240 plant species were assessed and identified to 158 genera and 42 families. Asteraceae family with 33 species, Papilionaceae with 32 species, Poaceae with 29 species, Apiaceae w ith 27 s pecies a nd Lamiaceae with 18 species prevailed and constituted 57.9% of all the plants observed. Investigation of species life forms showed that Hemicryptophyte plants were most important. Chorological study showed that species found in Irano-Turanian and Common areas of Irano-Turanian and Mediterranean eruption were the most important ecological groups in the region, while other chorotypes were positioned far from the next in importance.

Opis:: The insecticidal properties of essential oil derived via the hydro-distillation method from aerial parts of Artemisia judaica L. were tested against the cowpea weevil, Callosobruchus maculatus (Fab.) (Coleoptera: Bruchidae). The repellent activity assay of essential oil against C. maculates adults indicated that in concentrations of 63.7, 31.9, 15.9, 8.0 or 4.0 μg/cm2, the oil reduced egg laying by 92.5, 86.0, 61.8, 42.7 and 12.5%, respectively. Also, the residual-film assay showed that after 72 hours of treatment, concentrations of 50 and 40% were highly effective against the C. maculates adults. The sub-lethal effects of essential oil were investigated on fecundity and F1 progany by exposing adult females to treated seeds. Both LC25 and LC50 of essential oil significantly reduced F1 progany production compared to the control. The chemical composition of the essential oil was analyzed by GC-MS and the resulting oil piperitone (32.4%), camphor (20.6%) and (E)-ethyl cinnnamate (8.2%) were found to contain the major constituents of the oil. This provided the insecticidal properties of the essential oil against cowpea weevil.

Opis:: Fifty samples from five baby food products mainly made of cereal flour(s) were analyzed. The moisture contents of these products were between 11.14% and 11.9%, a level below 14.0%, the recommended level for safe storage of cereal grains and their products. The mycological analysis was carried out using the dilution plate method and two isolation media (DG18 for isolation of xerophilic fungi and DRBC for fungi in general). A total of 80 species related to 37 genera in addition to some unidentified fungal and yeast species were recorded on both media from the five products. The products were contaminated abundantly by xerophilic fungi which were occurring in 88% of food samples and accounting for 18.1% of the total CFU as recorded on DG18. The highest contamination level by xerophiles was registered in Mwebaza rice porridge (a component of rice flour) and the lowest in Mukuza (a product of maize, soyabean and sorghum flours). 11 xerophilic species were recorded of which Aspergillus and Eurotium (4 species each) were the predominant giving rise to 9.1% and 8.9% of the total CFU, with A. wentii, A. candidus, E. cristatum and E. repens were the most contaminating species. Of the fungi recorded other than xerophiles, species of Aspergillus (particularly A. flavus followed by A. niger), Penicillium (P. citrinum, P. oxalicum), Fusarium (F. solani, F. tricinctum), Cladosporium (C. sphaerospermum) and yeasts were the most predominant. Contamination of such foods is a matter of health hazard as these foods are for babies. So, the use of fresh, well-dried and uncontaminated flours for production of such foods is recommended.
