It emerges from bacteriological study that it is possible to isolate many bacterial types and yeasts from the lesions of footrot infection in sheep. Anaerobic cultivation came out with the isolation of Spherophorus spp. (24%), Bacteroides spp. (60%), Corynebacterium spp. (64%), Enterobacteracae (76%), Streptococcus spp. (76%), Staphylococcus spp. (36%), Clostridum sordellii (46%) and Irichosporon cutaneum (4%).  On the other hand aerobic cultivation rendered the isolation of Corynebacterium spp. (100%), Entrobacteracae (100%), Staphylococcus spp. (15%), Penicillium spp., Aspergillus fumigatus and Trichosporon cutaneum.  Five different drug combinations were studied for their efficacy in the treatment of ovine footrot. Their healing rates were as follows : oxytetracycline (59%), oxytetracyclin with formaline (70.9%), Procaine penicillin and streptomycin (72.5%), Procaine penicillin and streptomycin with formaline dipping (80.76%), Formaline alone (63.8%). All kinds of treatment indicated statistically significant differences to exit between the treated (experimental) and untreated (control) groups

The effect of a continuous disinfection programme, using the non-toxic disinfectant Virukill, in layers, on the spread and impact of infectious coryza, caused by Haemophilus paragallinarum was evaluated. In this experiment, both unvaccinated layers and layers vaccinated against infectious coryza were used. Duplicate smaller groups of vaccinated and unvaccinated chickens were challenged with different serovars of both NAD-dependent as well as NAD-independent isolates of Haemophilus paragallinarum. One group of chickens challenged with each of the different bacterial serovars was treated with the continuous disinfection programme, while the other group remained as the untreated controls. The clinical signs of infectious coryza were evaluated over a period of 20 days in each group. The egg production over this period was also evaluated. It was found in all experimental challenges, that the severity of the symptoms was reduced in the birds receiving the continuous disinfection programme. The drop in egg production was also found to be less severe in the treated groups when compared to the untreated control groups. The duration of infection was found to be either unchanged, or shorter in the birds treated with the continuous disinfection programme. In none of the experimental challenges was the duration or expression of clinical signs of IC increased due to the continuous disinfection programme.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.

Abstract Background The Placebo Group Simulation Approach (PGSA) aims at partially replacing randomized placebo-controlled trials (RPCTs), making use of data from historical control groups in order to decrease the needed number of study participants exposed to lengthy placebo treatment. PGSA algorithms to create virtual control groups were originally derived from mild cognitive impairment (MCI) data of the Alzheimer’s Disease Neuroimaging Initiative (ADNI) database. To produce more generalizable algorithms, we aimed to compile five different MCI databases in a heuristic manner to create a “standard control algorithm” for use in future clinical trials. Methods We compared data from two North American cohort studies (n=395 and 4328, respectively), one company-sponsored international clinical drug trial (n=831) and two convenience patient samples, one from Germany (n=726), and one from Switzerland (n=1558). Results Despite differences between the five MCI samples regarding inclusion and exclusion criteria, their baseline demographic and cognitive performance data varied less than expected. However, the five samples differed markedly with regard to their subsequent cognitive performance and clinical development: (1) MCI patients from the drug trial did not deteriorate on verbal fluency over 3 years, whereas patients in the other samples did; (2) relatively few patients from the drug trial progressed from MCI to dementia (about 10% after 4 years), in contrast to the other four samples with progression rates over 30%. Conclusion Conventional MCI criteria were insufficient to allow for the creation of well-defined and internationally comparable samples of MCI patients. More recently published criteria for MCI or “MCI due to AD” are unlikely to remedy this situation. The Alzheimer scientific community needs to agree on a standard set of neuropsychological tests including appropriate selection criteria to make MCI a scientifically more useful concept. Patient data from different sources would then be comparable, and the scientific merits of algorithm-based study designs such as the PGSA could be properly assessed.

A bacteriological study was conducted on fish and water from Congonhas River, Sertaneja (22º58’ S; 50º58’ W), Paraná State, Brazil. From 44% of the analysed fish, bacteria belonging to Pseudomonas, Acinetobacter, Aeromonas, Enterobacteriaceae, Micrococcus, Bacillus and Lactobacillus were isolated. The group most frequently isolated from fish was Aeromonas. In the water, the bacterial groups detected were Pseudomonas, Acinetobacter, Aeromonas, Enterobacteriaceae, Bacillus and Flavobacterium, from which Flavobacterium and Acinetobacter were the most abundant. The numbers of Colony Forming Units per millilitre of water varied from 3.1x10² to 1.0 x 10³. Although a clear pattern was not detected in the susceptibilities/resistances of the isolated strains to nine antimicrobial substances, Gram negative aerobic bacteria were more resistant than the other strains. A simultaneous resistance to furazolidone, oxolinic acid and norfloxacin, particularly in the bacteria isolated from fish, as well as in the aerobic strains isolated from water was observed. The antimicrobial substances to which less resistances were found were oxytetracycline in the strains isolated from water, and trimethoprim-sulphamethoxazole, oxytetracycline and chloramphenicol in those isolated from fish.

In this research, it was aimed to determine the effect of learning stations designed for astronomy subjects on the academic achievement of students and give an alternative method for teaching astronomy in the literature. The mixed approach in which mixed quantitative and qualitative methods were used together was preferred in the study. Among the quantitative methods, the pre-test and post-test model of the semi-experimental method was used; in addition, the protocols were applied about the method, which was used. The research was carried out with 98 seventh class students, who were under education in a secondary school located in the Eastern Anatolia Region of Turkey in the education year of 2015-2016. The quantitative data were analysed via the Astronomy Achievement Test (AAT) developed by the researchers and had 0,795 Cronbach Alpha reliability coefficient. The astronomy subjects in science lesson of the seventh class were studied with the experimental group through the learning stations; on the other hand, they were studied with the students in the control group through the activities stated in the textbook prepared by the Ministry of Education. The AAT was applied for the experimental, control groups using the pre- and post-tests, and data were analysed with the t-test. Meaningful difference was determined in AAT pre-test average scores of experimental and control groups; on the other hand, a meaningful difference was determined between the groups according to the independent samples t-test results applied with the average scores of the post-test(p<0.05). As a result of the analysis of the data gathered with the Station Observation Form (SOF), developed for the research, it was found out that the students recognise the learning stations as a technique of useful, entertaining, engaging, and easy-to-learn that enable them to learn astronomy topics effectively.Extended English abstract is in the end of Full Text PDF (TURKISH) file. ÖzetBu araştırmada, astronomi konuları için tasarlanan öğrenme istasyonlarının öğrencilerin akademik başarılarına etkisini belirlemek ve literatüre astronomi öğretimi için alternatif bir yöntem sunmak amaçlanmıştır.  Araştırmada karma nicel ve nitel yöntemlerin birlikte kullanıldığı karma yaklaşım tercih edilmiştir.

To evaluate the apoptosis in parotid glands of rats treated with midazolam associated or not with pilocarpine, 60 Wistar rats were assigned to 6 groups: control groups received saline solution for 30 days (S30) and 60 days (S60) and the other groups received pilocarpine for 60 days (P60), midazolam for 30 days (M30), midazolam for 30 days and 30 days of saline (M30 + S30), and finally midazolam for 30 days and 30 days of midazolam and pilocarpine (M30 + MP30). Histological sections were subjected to the TdT-mediated dUTP-biotin nick and labeling technique. The number of positive and negative cells was quantified, calculating the apoptotic index. ANOVA at 2 criteria and Tukey’s test were used. A greater apoptotic index was observed in the M30 (52.79 ± 9.01) and M30 + S30 (62.43 ± 8.52) groups when compared with the S30 (37.94 ± 5.94) and S60 (31.85 ± 9.18) groups, respectively (p < 0.05). There was no difference between M30 + MP30 (30.98 ± 6.19) and S60 (31.85 ± 9.18) groups regarding apoptotic index. Chronic administration of midazolam has been shown to increase the number of apoptotic cells in the parotid glands of rats. However, pilocarpine inhibited this effect, thus inhibiting the apoptosis.

Background: Streptococcus mutans play an important role in occurrence of dental caries objective: to compare the clinical and microbiological antibacterial outcomes of Mineral trioxide aggregate (MTA) and Calcium hydroxide cement Ca(OH)2. Methodology: 20 primary molars in 10 children with year’s 5-9 y .For each child one tooth was treated with Ca(OH)2 and the other with MTA. Finally, all the cavities were restored using compomer restorative material, and then microbiological parameters were recorded. Results: MTA treated teeth did not show any clinical sign or symptoms of failure. While three teeth treated with Ca(OH)2 were excluded because of necrosis. Changes in color and consistency of dentin were nearly the same for both groups. Microbiological evaluation showed a decrease in the count of Str. mutans with calcium hydroxide and complete killing of bacteria with MTA. Conclusion: The treatment showed satisfactory results of MTA as it was more potent inhibitor of bacterial-growth than Ca(OH)2

In order to test the possibility that the urinary concentrating defect associated with potassium depletion results from excessive water intake that accompanies potassium depletion, water intake was restricted in one half of a group of rats undergoing potassium depletion. The other one half of the group was allowed to drink ad libitum After 14 days, ability to concentrate the urine was tested in both groups as well as in two groups of control rats, one of which was allowed to drink ad libitum and the other having water intake restricted. Although both potassium-depleted groups concentrated urine less than the control groups, there was no difference in urine-concentrating ability between the two potassium-depleted groups. It is concluded that the urinary concentrating defect in potassium depletion is not due to excessive water intake.

Abstract Three herds (36-122 head per herd) of Angus cattle (cow-calf or yearling heifers) located at the Wye Research and Education Center, Queenstown, MD, were tagged with one of three ear tag formulations. On 17 May one of the herds was tagged with Optimizer tags (2 per head) and on 2 Jun the other 2 herds were tagged with Python tags (2 per head) or experimental YT-615 tags (1 per head). A herd of mixed-breed beef cattle located approximately 4 km from the treated cattle served as an untreated control. Fly density was determined by making biweekly counts on 15 cattle in each of the herds. Counts were made ol face flies/face, horn flies/animal, and stable flies/4 legs. Two (Optimizer herd) or 3 (other 2 herds) pretreatment and 11 or 10 posttreatment counts were made.

Three nonsense forms were differentially rewarded by having Ss spend them as money at the University Student Union. There were two control groups, one having comparable experience with the forms but not rewarded, the other having minimal experience. When the meaning of these forms, as measured by the semantic differential, was compared with the meaning of actual money (a dollar bill), the meanings were found to be consistent, that is, the nonsense forms used as money took on the same meaning as money. A secondary inference was that conceptual meaning processes serve an integrative function in perception.
