FSHR Single Nucleotide Polymorphism Frequencies in Proven Fathers and Infertile Men in Southeast Turkey

The influence of FSH receptor (FSHR) variants on male infertility is not completely understood. The present investigation is the first screening study for SNP at nucleotide position −29 in the core promoter region and codon 680 in exon 10 of the FSHR and the effect of the serum levels of FSH on male infertility in Southeast Turkey. The SNPs in codon 680 and at position −29 of the FSHR gene were analyzed by PCR-RFLP technique in 240 men with proven fathers, and 270 infertile men (150 nonobstructive azoospermic and 120 severe oligozoospermic). The separate analysis for SNP at nucleotide position −29 did not show any difference in genotypic frequencies and serum FSH levels. The genotype distribution of SNP at position 680 was different but does not influence serum FSH levels. Together the two SNPs form four discrete haplotypes (A-Thr-Asn, G-Thr-Asn, A-Ala-Ser, and G-Ala-Ser) occurring in 10 combinations. A statistically significant difference in the allelic distribution of G-Asn/G-Ser and G-Ser/G-Ser genotype between proven fathers and infertile men but there were not any statistically significant difference in the overall frequency of the four FSHR haplotypes. We conclude that the FSHR haplotype does not associate with different serum FSH levels but it is differently distributed in proven fathers and infertile men

Panel FMOLS Model Analysis of the Effects of Livestock Support Policies on Sustainable Animal Presence in Turkey

This paper studied the effects of livestock support policies applied in Turkey. The effects of the support policies were built upon the change in the cattle presence data. Full Modified Ordinary Least Square (FMOLS) model was used in the analysis. In the panel dataset which was created for the study, the time period was taken as the years between 2004 and 2014 and the cross-section was 26 sub-regions. The results of panel FMOLS test for both the total livestock supports and each support component presents important details. According to the results of the analyses, a 1.0% increase in livestock supports leads to a 0.3% increase in animal presence in Turkey. On the other hand, it is stated that the utilization rate of the support payments is high in the western regions, whereas it is comparatively low in the eastern and interior regions in Turkey although the appliance of the policies is carried out in the same way, since animal presence in western regions in terms of fertile races is higher. This situation reveals the importance of breeders of high conscience, educational level, and agricultural income besides organized associations and provincial organizations

The effects of exchange rate volatility on trade: evidence from Turkish agricultural trade

WOS:000301655100013In this article, an empirical study of the effect of Real Effective Exchange Rate Volatility (REERV) on Agricultural Export (AGX) and Agricultural Import (AGM) in Turkey was conducted. Studied period covers 1995 to 2007. In order to reach REERV, Generalized Autoregressive Conditional Heteroscedasticity (GARCH) (1,1) model was used. Long-term relationship between series was determined using Johansen cointegration test. The direction of this relationship, on the other hand, was determined using pairwise Granger causality. Our empirical results indicated that there was a positive long-termrelationship between REERV and AGX series, while there was a negative long-term relationship between REERV and AGM. The relationship is unidirectional for both AGX and AGM series

Stubble Burning and Consciousness Level of Farmers

This study analyses the consciousness levels, attitudes and behaviours of farmers against stubble burning and the damages of stubble burning which is a part of land misuse. 86 farmers from 9 villages in Zile county of Tokat province were surveyed for the study. These data was used to state farmers' socio-demographical characteristics and their behaviours against stubble burning was analysed. According to the study results, 99% of the farmers says that stubble burning is a wrong application. They states that stubble burning causes natural damages and the most importantly it is harmful by 76% to the living creatures in the nature. 57% of them prefers the method of mixing stubble to the soil

The studied period covers between 2005:01 – 2008:10. GARCH models are used to obtain the volatility series of the agriculture and food prices. Johansen co-integration and impulse-response analyses are used to determine the long term relationship between the series. According to the analysis results, it is found out that there has been a long term relationship between the agriculture and food prices and the inflation in Turkey, and the uncertainty of the agriculture and food prices have a positive effect on the inflation

The causality between energy consumption and economic growth in Turkey

This paper applies the causality test to examine the causal relationship between primary energy consumption (EC) and real Gross National Product (GNP) for Turkey during 1970-2006. We employ unit root tests, the augmented Dickey-Fuller (ADF) and the Philips-Perron (PP), Johansen cointegration test, and Pair-wise Granger causality test to examine relation between EC and GNP. Our empirical results indicate that the two series are found to be non-stationary. However, first differences of these series lead to stationarity. Further, the results indicate that EC and GNP are cointegrated and there is bidirectional causality running from EC to GNP and vice versa. This means that an increase in EC directly affects economic growth and that economic growth also stimulates further EC. This bidirectional causality relationship between EC and GNP determined for Turkey at 1970-2006 period is in accordance with the ones in literature reported for similar countries. Consequently, we conclude that energy is a limiting factor to economic growth in Turkey and, hence, shocks to energy supply will have a negative impact on economic growth.Energy consumption Economic growth Granger causality

The Present and Future Statues of Animal Presence in Turkey; The Declination of TR83 Area

In this study, the cattle and small cattle presence in Turkey and in the area of TR83 which consists of Amasya, Çorum, Samsun and Tokat provinces were analysed. Trend analysis were carried out using the data obtained from cattle and small cattle presence with the help of the values of the period of 1996 – 2014 and estimated values for 2020 were specified. It is seen in the projections for the 2020 that, domestic cattle breeds are expected to be decreased in number whereas it is expected to be increased in the TR83 area. Also it is estimated that the number of the whole animal existence which are investigated by the study will increase by the year 2020. It is beyond question that the positive effects of the present policies supporting stockbreeding on this increase is apparent. In this sense, the determination of the contribution of present stockbreeding support policies to the sector and their effectiveness and the investigation of their faulting aspects are important in order to develop more accurate and effective policies

Epidemiology

BackgroundClimate change is expected to result in more heat-related, but potentially fewer cold-related, emergency department visits and deaths. The net effect of projected changes in temperature on morbidity and mortality remains incompletely understood. We estimated the change in temperature-related morbidity and mortality at two sites in southern New England, USA through the end of the 21st century.MethodsWe used distributed lag Poisson regression models to estimate the present-day associations between daily mean temperature and all-cause emergency department visits and deaths in Rhode Island and in Boston, Massachusetts. We estimated the change in temperature-related visits and deaths in 2045\u20132054 and 2085\u20132094 (relative to 2001\u20132010) under two greenhouse gas emissions scenarios (RCP4.5 and RCP8.5) using downscaled projections from an ensemble of over 40 climate models, assuming all other factors remain constant.ResultsWe observed U-shaped relationships between temperature and morbidity and mortality in Rhode Island, with minima at 10.9 \ub0C and 22.5 \ub0C, respectively. We estimate that, if this population were exposed to the future temperatures projected under RCP8.5 for 2085\u20132094, there would be 5976 (95% eCI: 1630, 11,379) more emergency department visits but 218 (95% eCI: 12551, 43) fewer deaths annually. Results were similar in Boston, and similar but less pronounced in the 2050s and under RCP4.5.ConclusionsWe estimate that in the absence of further adaptation, if the current southern New England population were exposed to the higher temperatures projected for future decades, temperature-related emergency department visits would increase, but temperature-related deaths would not.20182019-07-01T00:00:00ZF32 ES027742/ES/NIEHS NIH HHS/United StatesUE1 EH001040/EH/NCEH CDC HHS/United States29561281PMC5980746687

Modal identification of the first Bosporus bridge during hanger replacement

As the oldest of the three suspension bridges spanning the Bosporus, the (First) Bosporus Bridge wascommissioned in 1973. Its main span of 1074 m was originally designed to be suspended by inclinedhangers; in 2015, the original inclined hangers were replaced by vertical ones. In-situ ambient vibra-tion measurements were taken at different stages of this operation to gain an understanding of theeffects of the hanger cable orientation on the overall dynamic behaviour of the bridge. Measurementswere also recorded for various periods spanning several weeks to observe operational variations onthe modal frequencies of vibration. Measurements were made on the tower, the deck and the hang-ers. It was observed that, as a result of the hanger replacement, frequencies of the modes involvingpredominant deck motion decreased on the order of 6 to 16% while the frequencies of the modesinvolving predominant tower motion showed almost no change. A finite element model of the Bridgewas also developed to further investigate the physical reasons behind the observed changes in modalfrequencies and similar trends were observed in the modal frequencies yielded by the finite elementmodels developed for the inclined and the vertical hanger configurations.WOS:000511783100001Scopus - Affiliation ID: 60105072Science Citation Index ExpandedQ2ArticleUluslararası işbirliği ile yapılmayan - HAYIRAralık2020YÖK - 2020-2
