Determination of the Effect of Drought Stress on the Seed Germination in Some Plant Species

Especially the use of drought‐resistant plant species reduces maintenance and irrigation costs, and plants increase the retention and success to continue its life in arid landscape. In this study, some plant species used have been studied to determine their tolerance to drought stress in gardens and parks in Kastamonu. For this purpose, germination trials have been in conducted -2, -4, -6, and -8 Bar water stress. Landscaping applications commonly used some species such as Cupressus sempervirens L., Ailanthus altissima (Mill.) Swingle, Pyracantha coccinea Roem, Thuja orientalis, Pinus sylvestris L., Sophora japonica, Cedrus libani A. Rich., Acer pseudoplatanus L., Pinus brutia Ten., and Pinus nigra Arnold. ssp. pallasiana (Lamb.) Holmboe. Their seeds were evaluated different levels of water stress in the germination percentage. PEG 6000 solution was used in the formulation of water stress. The seeds were exposed to constant temperature of 25°C for a period of 35 days at germination cabinet. As a result, this experiment calculated germination in different water stress levels what percentage has fallen, so the least affected by increased water stress was studied to determine the species. Also results showed increased water stress and reduce the percentage of germination in all species. The highest level of water stress -8 Bar, which was also obtained stress level proportional germination values Pinus nigra Arnold. ssp. pallasiana (Lamb.) Holmboe (64.8%) and Pinus brutia Ten. (46.5%)

Mesons spectral functions at finite temperature

Azizi, Kazem (Dogus Author) -- It was firstly submitted to 3rd International Conference on Hadron Physics, TROIA'11.We investigate the thermal spectral densities for (pseudo)scalar and vector currents in the framework of the real time formalism when mass of two quarks are different. Such spectral densities are necessary for the phenomenological investigation of in-medium properties of hadrons. We use the quark propagator at finite temperature and calculate annihilation and scattering parts of spectral densities for above mentioned currents. The investigations show that the thermal contributions are significantly important. The obtained results at T 0 limit are in good consistency with the vacuum results.Ozyegin University, Middle East Technical University, Canakkale Onsekiz Mart University, HadronPhysics2 Consortium

The Effects of Aerobic and Anaerobic Training Programs Applied to Elite Wrestlers on Body Mass Index (BMI) and Blood Lipids

The purpose of this study is to analyse the effects of aerobic and anaerobic training programs applied to elite wrestlers on body mass index (BMI) and blood lipids. 20 elite wrestlers, whose average age is (experimental group; 15.20±4.61, n=10), control group; 15.90±2.08, n=10), participated in the study and they were randomly divided into two groups. Strength and endurance training programme based on “one day aerobic, one day anaerobic” principles was applied to the experimental group six days a week for eight weeks. The control group went on doing normal routine wrestling technical training. Before and after eight-week training program, BMI, Triglyceride, HDL-C, VLDL, Cholesterol, LDL blood values were taken from the experimental and the control group by body analyser. According to the results of the study, none of the blood lipid indicators of the control group did significantly changed from pretest to posttest. (p>0.05). However, HDL-C, cholesterol and LDL values from blood lipids indicators of the experimental group changed significantly from pretest to posttest. (p<0.05). There were no significant changes in body mass index (BMI), Triglyceride and VLDL. As a result, this study revealed that there was no significant difference in the control group which did exercise routinely, while the training programme with changeable type and volume made significant differences in the experimental group.In statistical analyses, paired- samples t test was used for intra-group comparisons, and independent sample t test was used for inter-group comparisons. The significance level was determined as p<0.05. For all the values, mean and standard deviation were used

The Effects of Whole Body Vibration Training on Some Biochemical Values in Terms of Osteoporosis Risk in Premenopausal Women

The main purpose of the present study is to comparatively examine the effects of Whole body vibration (WBV) trainings on some biochemical bone-turnover markers (Beta-CTx, Osteocalcin) in terms of osteoporosis. Twenty-four sedentary women (mean age=37.12±1.84 years) participated in the study. The participants were randomly divided to 3 groups: whole body vibration exercise group (WBV, n=8), classical resistance exercise group (CR, n=8), and control group (CO, n=8). Vibration trainings and classical resistance trainings were applied in similar exercise models for major muscle groups three days a week for eight weeks, not on consecutive days but in the same contexts. Of biochemical values, Beta-CTx and Osteocalcin were analysed by using Cobas e 411 ECLIA (Electro Chem. Luminance Immune Assay) method before and after the eight-week exercise period. For intra-group comparisons paired-samples t-test, for inter-group comparisons one way ANOVA, and for multi-comparisons Tukey test were used. While a statistically significant difference was found between pretest posttest of Beta-CTx and Osteocalcin values of CR (p.05). A statistically significant difference was found between the groups in terms of pretest posttest biochemical value changes (Beta-CTx, Osteocalsin) of the participants (p<.05). As a result, eight-week WBV training in premenopausal women can be considered as safe in terms of biochemical values’ (Beta-CTx, Osteocalcin) remaining unchanged. On the other hand, CR training made significant changes on the values in question. Whether this change is an acute effect or not has become a raising question. This case can be studied in premenopausal women in further research

Effect of PDE 5 Inhibitor-Avanafil on Renal Ischemia/Reperfusion Injury in Rats

Aim:Renal ischemia-reperfusion injury (RI/RI) damages many organs, especially the kidney. Phosphodiesterase (PDE) 5 inhibitors has antioxidant and anti-inflammatory effects. Avanafil (AVA) is a second-generation PDE 5 inhibitor with greater PDE isoform selectivity. The aim of this study is to investigate the effects of AVA on RI/RI in rats.Materials and Methods:Forty rats were randomly divided into five groups (n=8): Sham; AVA 10; RI/RI; RI/RI + 5 mg/kg AVA, and RI/RI + 10 mg/ kg AVA. RI/RI in rats was established by clamping renal artery. An acute surgical experiment was performed for the induction of renal ischemia for 45 min by renal artery clamping followed by reperfusion for 24 h. Kidney tissues were investigated biochemically [malondialdehyde (MDA) and glutathione (GSH) with ELISA], molecularly [relative quantification of IL-1β, nuclear factor-kappa B (NF-κB), and tumor necrosis factor-alpha (TNF-α) mRNA gene expression with qRT-PCR], and histopathologically (staining with Harris hematoxylin and eosin Y).Results:AVA administration ameliorated disturbances in MDA and GSH levels caused by RI/RI. AVA treatment improved the increase in the mRNA expressions of IL-1β, NF-κB, and TNF-α in kidney tissues induced ischemia/reperfusion injury. AVA administration ameliorated histopathologic injury in kidney tissues caused by renal ischemia reperfusion. Moreover, the values closest to those of the sham group were obtained by administering 10 mg/kg AVA to rats with RI/RI.Conclusion:AVA administration improved renal ischemia/reperfusion-induced tissue injury by alleviating oxidative stress and inflammatory cascades that could be important in ischemia-reperfusion injury. These findings may provide a mechanistic basis for using AVA to treat RI/RI

The transport of mercury(II) ion by a zwitterionic dithiophosphonate 1 in the liquid membrane was studied and the kinetic behavior of the transport process as a function of concentration, temperature, stirring rate and solvents was investigated. The compound 1 is expected to serve as a model liquid membrane transport with mercury(II) ions.Conclusion: A kinetic study of mercury(II) transport through a membrane assisted by O-(1,3-Bispiperidino-2-propyl)4-methoxy phenyldithiophosphonate was performed. It can be concluded that the compound 1 can be provided a general and straightforward route to remove toxic metals ions such as mercury(II) ion from water or other solution

In a real-life setting, direct-acting antivirals to people who inject drugs with chronic hepatitis c in Turkey

Background: People who inject drugs (PWID) should be treated in order to eliminate hepatitis C virus in the world. The aim of this study was to compare direct-acting antivirals treatment of hepatitis C virus for PWID and non-PWID in a real-life setting. Methods: We performed a prospective, non-randomized, observational multicenter cohort study in 37 centers. All patients treated with direct-acting antivirals between April 1, 2017, and February 28, 2019, were included. In total, 2713 patients were included in the study among which 250 were PWID and 2463 were non-PWID. Besides patient characteristics, treatment response, follow-up, and side effects of treatment were also analyzed. Results: Genotype 1a and 3 were more prevalent in PWID-infected patients (20.4% vs 9.9% and 46.8% vs 5.3%). The number of naïve patients was higher in PWID (90.7% vs 60.0%), while the number of patients with cirrhosis was higher in non-PWID (14.1% vs 3.7%). The loss of follow-up was higher in PWID (29.6% vs 13.6%). There was no difference in the sustained virologic response at 12 weeks after treatment (98.3% vs 98.4%), but the end of treatment response was lower in PWID (96.2% vs 99.0%). In addition, the rate of treatment completion was lower in PWID (74% vs 94.4%). Conclusion: Direct-acting antivirals were safe and effective in PWID. Primary measures should be taken to prevent the loss of follow-up and poor adherence in PWID patients in order to achieve World Health Organization’s objective of eliminating viral hepatitis

Peri-operative red blood cell transfusion in neonates and infants: NEonate and Children audiT of Anaesthesia pRactice IN Europe: A prospective European multicentre observational study

BACKGROUND: Little is known about current clinical practice concerning peri-operative red blood cell transfusion in neonates and small infants. Guidelines suggest transfusions based on haemoglobin thresholds ranging from 8.5 to 12 g dl-1, distinguishing between children from birth to day 7 (week 1), from day 8 to day 14 (week 2) or from day 15 (≥week 3) onwards. OBJECTIVE: To observe peri-operative red blood cell transfusion practice according to guidelines in relation to patient outcome. DESIGN: A multicentre observational study. SETTING: The NEonate-Children sTudy of Anaesthesia pRactice IN Europe (NECTARINE) trial recruited patients up to 60 weeks' postmenstrual age undergoing anaesthesia for surgical or diagnostic procedures from 165 centres in 31 European countries between March 2016 and January 2017. PATIENTS: The data included 5609 patients undergoing 6542 procedures. Inclusion criteria was a peri-operative red blood cell transfusion. MAIN OUTCOME MEASURES: The primary endpoint was the haemoglobin level triggering a transfusion for neonates in week 1, week 2 and week 3. Secondary endpoints were transfusion volumes, 'delta haemoglobin' (preprocedure - transfusion-triggering) and 30-day and 90-day morbidity and mortality. RESULTS: Peri-operative red blood cell transfusions were recorded during 447 procedures (6.9%). The median haemoglobin levels triggering a transfusion were 9.6 [IQR 8.7 to 10.9] g dl-1 for neonates in week 1, 9.6 [7.7 to 10.4] g dl-1 in week 2 and 8.0 [7.3 to 9.0] g dl-1 in week 3. The median transfusion volume was 17.1 [11.1 to 26.4] ml kg-1 with a median delta haemoglobin of 1.8 [0.0 to 3.6] g dl-1. Thirty-day morbidity was 47.8% with an overall mortality of 11.3%. CONCLUSIONS: Results indicate lower transfusion-triggering haemoglobin thresholds in clinical practice than suggested by current guidelines. The high morbidity and mortality of this NECTARINE sub-cohort calls for investigative action and evidence-based guidelines addressing peri-operative red blood cell transfusions strategies.
