Determination of production losses related to lumpy skin disease among cattle in Turkey and analysis using SEIR epidemic model.

BACKGROUND: Lumpy Skin Disease (LSD) is an infectious disease induced by the Capripoxvirus, causing epidemics in Turkey and several countries worldwide and inducing significant economic losses. Although this disease occurs in Turkish cattle every year, it is a notifiable disease. In this study, LSD in Turkey was modelled using the Susceptible, Exposed, Infectious, and Recovered (SEIR) epidemiological model, and production losses were estimated with predictions of the course of the disease. The animal population was categorized into four groups: Susceptible, Exposed, Infectious, and Recovered, and model parameters were obtained. The SEIR model was formulated with an outbreak calculator simulator applied for demonstration purposes. RESULTS: Production losses caused by the LSD epidemic and the SEIR model's predictions on the disease's course were evaluated. Although 1282 cases were identified in Turkey during the study period, the prevalence of LSD was calculated as 4.51%, and the mortality rate was 1.09%. The relationship between the disease duration and incubation period was emphasized in the simulated SEIR model to understand the dynamics of LSD. Early detection of the disease during the incubation period significantly affected the peak time of the disease. According to the model, if the disease was detected during the incubation period, the sick animal's time could transmit the disease (Tinf) was calculated as 2.66 days. Production loss from LSD infection was estimated at US $ 886.34 for dairy cattle and the US $ 1,066.61 for beef cattle per animal. CONCLUSION: Detection of LSD infection during the incubation period changes the course of the disease and may reduce the resulting economic loss.

A meta-analysis of the effects of synchronization protocols applied to sheep in Turkey on pregnancy rates during breeding and non-breeding seasons.

This study aimed to determine common pregnancy rates and effect sizes with meta-analysis of studies investigating the effect of different synchronization protocols applied to sheep during breeding and non-breeding seasons on pregnancy rates. Common pregnancy rates were estimated by coalescing pregnancy rates of studies performed independently, and heterogeneity between the studies was investigated. The meta-analysis included 24 studies that determined pregnancy rates in 78 different groups consisting of 1934 sheep with five different synchronization protocols in Turkey between 2001 and 2020. Among the different synchronization methods, the P4+PMSG group (90.37%) during the breeding season and P4+PGF2α (69.77%) and P4 (68.75%) groups during the non-breeding season showed the highest pregnancy rate. Also, the effect size of P4+PMSG application during the breeding season was calculated as 0.934 (95% confidence interval: 0.901-0.967), and the effect size of P4+PGF2α application during the non-breeding season was calculated as 0.709 (95% confidence interval: 0.406-1.013). To conclude, the combination of P4+PMSG during the breeding season and progestogen and other hormone applications during the non-breeding season are the most effective methods for estrus synchronization and for achieving the desired pregnancy rates.

Factors affecting the price of raw milk in Turkey using panel data analysis / Fatores que afetam o preço do leite cru na Turquia usando análise de dados em painel

ABSTRACT: The high costs of feed among the total costs of raw milk production and an unfavorable milk-feed ratio directly affect the profitability of milk producers. To understand how the market in Turkey can be equilibrated, an exploration of the factors affecting milk prices is essential. This study determined the effects of the basic and the economic indicators on the price of raw milk between 2010 and 2019, by analyzing the monthly panel data. Since time series data are used, Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) tests are conducted to find out whether the series is stationary. In order to see the individual effects, the parameters are estimated using the fixed and random-effects models. The Hausman test is conducted to decide which of the two models is valid. The basic indicators for milk price, namely, prices of barley, soybean meal, wheat and distillers dried grains with soluble (DDGS), and the economic indicators, namely, dollar exchange rate and agricultural producer price index (PPI) had significant (P < 0.05; P < 0.01) effects on the milk price. In conclusion, it is reported that the raw milk prices in Turkey are considerably affected by the prices of feed ingredients as well as the general economic conditions.

RESUMO: Os elevados custos da ração entre os custos totais para a produção de leite cru e uma relação leite-ração desfavorável afetam diretamente a lucratividade dos produtores de leite. Para entender como o mercado na Turquia pode ser equilibrado, é essencial explorar os fatores que afetam os preços do leite. Este estudo pretende determinar os efeitos dos indicadores básicos e econômicos sobre o preço do leite cru entre 2010 e 2019, por meio da análise de dados em painel mensal. Como os dados de série temporal são usados, os testes de Dickey-Fuller Aumentado (ADF) e Phillips-Perron (PP) são conduzidos para descobrir se a série é estacionária. Para ver os efeitos individuais, os parâmetros são estimados usando os modelos de efeitos fixos e aleatórios. O teste de Hausman é realizado para decidir qual dos dois modelos é válido. Encontram-se os indicadores básicos do preço do leite.Os preços da cevada, farelo de soja, trigo e grãos secos de destilaria com solúveis (DDGS), e os indicadores econômicos. A taxa de câmbio do dólar e o índice de preços ao produtor agrícola (PPI), ter efeitos significativos (P < 0,05; P < 0,01) no preço do leite. Em conclusão, verifica-se que os preços do leite cru na Turquia são consideravelmente afetados pelos preços dos ingredientes para rações, bem como pelas condições económicas gerais.

Quorum sensing signals and related virulence inhibition of Pseudomonas aeruginosa by a potential probiotic strain's organic acid.

Studies conducted in recent years show that pathogen bacteria are not asocial assets and they use the cell to cell communication mechanism called quorum sensing that depends on population density to adapt changing environmental conditions. This mechanism is coordinate gene expression of various bacterial factors like bioluminescence, antibiotic biosynthesis, plasmid conjugation and virulence. Bacteria communicate with each other by producing signal molecules and regulate the production of virulence factors that have importance in the pathogenity formation. Virulence mechanisms of Pseudomonas aeruginosa, which causes various types of infections in humans, are also regulated by quorum sensing. Nowadays, biotechnological researches are focused on the development of homoserine lactone antagonists. The use of these type of molecules are considered to be a new treatment approach for blocking communication between bacteria and reducing virulence, therefore improving infection control. In this study, lactic acid of a potential probiotic Pediococcus acidilactici M7 strain isolated from newborn faeces was used to evaluate the inhibitory effect on quorum sensing signal molecules and some virulence factors of clinical Pseudomonas aeruginosa isolates. Results showed that lactic acid has an inhibitory effect on short-chain HSL production and swarming-swimming-twitching motility, elastase, protease, pyocyanin, and biofilm production of Pseudomonas aeruginosa isolates in certain quantities that are regulated by the quorum sensing system.

Age and Aortic Diameters in Pilots.

BACKGROUND: Pilots are exposed to various physical and hemodynamic stresses during flight. Aortic dilatation may be one of the important consequences of flight-related stress. In this study, we evaluated whether or not variation in aortic diameter was associated with the type of aircraft and the age of pilots. MATERIALS AND METHODS: Medical records of 87 jet aircraft pilots (JP) (mean age = 30.0 ± 7.0 years) and 65 non-jet aircraft pilots (NJP) (mean age = 32.63 ± 5.7) were reviewed. Echocardiographic diameters of the aortic sinus (AoS) and ascending aorta (AoAsc) were measured using standard echo probe positions. RESULTS: Aortic diameters were not statistically different between JP and NJP. Regression analysis revealed that the diameters of the AoS (R = 0.484, R(2) = 0.234, p < 0.001) and AoAsc (R = 0.514, R(2) = 0.264, p < 0.001) were significantly associated with age in the JP group. Whereas, there was not any relationship found between age and the diameters of the AoS and AoAsc in the NJP group. CONCLUSION: Jet pilots had aortic enlargement as they became older in contrast to the NJP group. Although the aortic diameters were not within the critical ranges in the JP group, these results could suggest that flight-related stresses might result in acute aortic syndromes in the long term.

Examining the relationship between authenticity and self-handicapping.

Self-handicapping includes strategies of externalization in which people excuse failure and internalize success, but which also prevents them from behaving in an authentic way. The goal was to investigate the relation of authenticity with self-handicapping. The study was conducted with 366 university students (176 men, 190 women; M age = 20.2 yr.). Participants completed the Turkish version of the Authenticity Scale and the Self-handicapping Scale. Self-handicapping was correlated positively with two factors of authenticity, accepting external influence and self-alienation, and negatively with the authentic living factor. A multiple regression analysis indicated that self-handicapping was predicted positively by self-alienation and accepting external influence and negatively by authentic living, accounting for 21% of the variance collectively. These results demonstrated the negative association of authenticity with self-handicapping.

The effect of hyperbaric oxygen therapy on ischemia-modified albumin levels in people with diabetes with foot ulcers.

INTRODUCTION: Hyperbaric oxygen (HBO2) treatment accelerates the healing process of diabetic foot ulcers (DFU) by increasing tissue oxygenation in hypoxic tissues. Ischemia-modified albumin (IMA) is produced as a result of serum albumin flowing through ischemic tissues. We aimed to investigate the effect of HBO2 therapy on IMA levels in patients with DFU. METHODS: Thirty (22 male, eight female) patients with DFU were enrolled into this study. HBO2 therapy was performed five times a week. Blood samples were drawn before the first treatment, after the 10th (IMA10) and 20th (IMA20) hyperbaric sessions. RESULTS: Pretreatment IMA levels [median (25%-75% quartiles)] of the patients were 0.010 (0.002-0.150) absorbance units (ABSU). Compared to pretreatment values, IMA levels did not change significantly after the 10th session [0.006 (0.003-0.025) ABSU] and 20th session [0.009 (0.005-0.019) ABSU] (p = 0.527). We found statistically significant negative correlations between diabetic age and IMA10 (r = -0.448, p = 0.013) and IMA20 (r = -0.414, p = 0.023). CONCLUSION: In contrast to our expectations, IMA levels did not change with HBO2 therapy in patients with DFU. We think that IMA levels did not decrease due to the production of free oxygen radicals during HBO2 therapy. Further studies with larger groups may give more accurate results.

Predictive role of authenticity on psychological vulnerability in Turkish university students.

Authenticity is associated with adaptive psychological characteristics and may be predictive of psychological vulnerability. The study was conducted with Turkish university students (N = 303; 158 women, 145 men; M age = 20.1 yr.). Participants completed the Turkish version of Authenticity Scale and the Psychological Vulnerability Scale. Psychological vulnerability was correlated positively with two subfactors of authenticity, accepting external influence and self-alienation, and negatively with the authentic living factor of authenticity. Self-alienation, accepting external influence, and authentic living were related to psychological vulnerability, accounting for 33% of the variance collectively. Authenticity is an important predictor of psychological vulnerability.

Hierarchical regression analysis showed that Facebook addiction partially mediated the relationship between subjective vitality and subjective happiness.

Cardiac responses to long duration and high magnitude +Gz exposure in pilots: an observational study.

OBJECTIVE: In military aviation, high performance aircraft pilots are exposed to +Gz acceleration at longer durations and higher magnitude than transport/helicopter pilots. The purpose of this study was to reveal the negative or positive cardiac responses to this occupational high +Gz exposure. METHODS: Our study design was cross-sectional and observational. We have evaluated 21 echocardiographic parameters of 63 pilots who applied for aircrew periodic medical examination. Of 63 pilots, 33 were grouped as high performance aircraft pilots group (Group A) and 30 were grouped as control group (Group B) whose aircraft type was transport or helicopter. Means of demographic and echocardiography parameters between two groups were compared statistically with Student's t-test, Mann- Whitney U or Chi-square test as appropriate. RESULTS: Among all echocardiographic parameters, mean TV A (tricuspid valve peak velocity during late diastolic filling) was significantly higher and TV E (peak velocity during early diastolic filling)/ A ratio was significantly lower for Group A pilots (p<0.05). In Group A pilots, mean TV A and TV E/A ratio were (52.12 ± 13.85) and (1.36 ± 0.30) respectively. In Group B pilots, mean TV A and TV E/A ratio were (42.61 ± 6.42) and (1.53 ± 0.20) respectively (p=0.001 for TVA and p=0.005 for TV E/A). Mean pulmonary artery pressure (PAP) of Group A pilots (32.04 ± 9.09) was higher than Group B pilots (28.76 ± 7.9) but it was not statistically significant (p>0.05). CONCLUSION: We conclude that according to the results of our study, long term +Gz exposure has no effects on cardiac morphologic and systolic functions but has effects on right ventricular diastolic functions. We have considered that these effects may be a result of chronic +Gz adaptation or high PAP levels.
