Genetic Modification of Plant Hormones Induced by Parasitic Nematodes, Virus, Viroid, Bacteria, and Phytoplasma in Plant Growing

Plant hormones, such as auxin, play crucial roles in many plant developmental processes, which is crosstalk with gibberellin and strigolactone. The roles of hormones may vary in the biosynthesis of metabolisms. During the pathogen attack, including plant-parasitic nematodes, viroid, phytoplasma, virus, and bacteria, plant hormones are involved in several plant processes. Ethylene (ET), salicylate (SA), jasmonate (JA), and abscisic acid (ABA) primarily regulate synergistically or antagonistically against pathogens. Those pathogens—nematodes, bacteria, viroid, phytoplasma, and viruses regulate several plant hormones for successful parasitism, influencing the phytohormone structure and modifying plant development. Several genes are related to plant hormones that are involved in pathogens parasitism. In this chapter, how pathogens affect plant hormones in plants growing are discussed

Host-Pathogen and Pest Interactions: Virus, Nematode, Viroid, Bacteria, and Pests in Tomato Cultivation

Several pathogens and pests damage tomato plants, and only one and/or more pathogens and pests can coexist in the same plant at the same time. As several numerous pathogens are found in the same plant, the damage to the tomato plants is higher. Pathogens such as nematodes, viruses, viroids, bacteria, and insects adversely affect the growth and development of tomato plants. They may infect roots or upper part of the plant and can cause not only slow down the growth of plants, but also crop losses and their death. Damaging of plant caused by pathogens and pests reduces the market value of plant products. Those pathogens and pests are also called biotic stress agents. The damage, mode of infection, and the mechanism of infection in each tomato plant and pathogens might be different. This situation is crucially important to understand plant pathogen relationship in detail in terms of controlling pests and pathogen. The effect of each pest/pathogen on tomato plants during the cultivation, the type of damage, and new developments and perspectives on morphological and molecular aspects in tomato-pathogen interactions will be discussed in this chapter

Selective ROCK2 inhibition in focal cerebral ischemia

Objective: Rho-associated kinase (ROCK) is a key regulator of numerous processes in multiple cell types relevant in stroke pathophysiology. ROCK inhibitors have improved outcome in experimental models of acute ischemic or hemorrhagic stroke. However, the relevant ROCK isoform (ROCK1 or ROCK2) in acute stroke is not known. Methods: We characterized the pharmacodynamic and pharmacokinetic profile, and tested the efficacy and safety of a novel selective ROCK2 inhibitor KD025 (formerly SLx-2119) in focal cerebral ischemia models in mice. Results: KD025 dose-dependently reduced infarct volume after transient middle cerebral artery occlusion. The therapeutic window was at least 3 h from stroke onset, and the efficacy was sustained for at least 4 weeks. KD025 was at least as efficacious in aged, diabetic or female mice, as in normal adult males. Concurrent treatment with atorvastatin was safe, but not additive or synergistic. KD025 was also safe in a permanent ischemia model, albeit with diminished efficacy. As one mechanism of protection, KD025 improved cortical perfusion in a distal middle cerebral artery occlusion model, implicating enhanced collateral flow. Unlike isoform-nonselective ROCK inhibitors, KD025 did not cause significant hypotension, a dose-limiting side effect in acute ischemic stroke. Interpretation Altogether, these data show that KD025 is efficacious and safe in acute focal cerebral ischemia in mice, implicating ROCK2 as the relevant isoform in acute ischemic stroke. Data suggest that selective ROCK2 inhibition has a favorable safety profile to facilitate clinical translation

Aims: The objective of this randomised controlled trial was to compare the efficacy of two techniques for increasing the amount of keratinised mucosa around implants: free gingival grafts versus classic vestibuloplasty

Clinicopathologic characteristics and treatment features of women with the incidental diagnosis of endometrial adenocarcinoma during infertility follow-up in Ankara, Turkey

AbstractObjectiveThe aim of this study was to investigate the clinical and laboratory features of patients with the incidental diagnosis of endometrial adenocarcinoma (EC) during infertility work-up, with special attention given to treatment approaches, recurrence rate, and fertility outcome.Material and MethodsThe medical records of 577 patients who were diagnosed with EC and treated between 2007 and 2013 were included in the study. Out of 577 EC patients, 5.1% (n = 30) were ≤ 40 years of age. However, 10 patients had a history of infertility and had been diagnosed during evaluation for infertility. Patients' clinical and laboratory data were reviewed retrospectively.ResultsThe mean age at diagnosis was 34.3 ± 4.5 years and the mean duration of infertility was 5.1 ± 4.7 years. Immediate staging surgery was performed on three patients. The others were treated with oral megestrol acetate and/or a levonorgestrel-containing intrauterine device (IUD) for 6 months. The mean duration of postoperative or postdiagnostic follow-up was 44.7 ± 25.9 months. The disease persistence and recurrence rates were 11.1% and 22.2%, respectively. Two patients achieved pregnancy naturally or by assisted reproductive technology (ART) trial.ConclusionThe investigation of patients during infertility work-up provides an opportunity to evaluate the endometrium and its malignancies in young women, when the disease is in its early stage and symptom free. The standard surgical treatment for early-stage EC is total hysterectomy with bilateral salpingo-oophorectomy. However, conservative management of early stage EC with progestational drugs, especially in young patients who wish to preserve their fertility, is acceptable with the possibility of future pregnancies

Dose-dependent neuroprotective effect of enoxaparin on cold-induced traumatic brain injury

Recent evidence exists that enoxaparin can reduce brain injury because of its anticoagulant activity. To investigate the potential therapeutic effect of enoxaparin on cold-induced traumatic brain injury, at 20 minutes after modeling, male BALB/c mouse models of cold-induced traumatic brain injury were intraperitoneally administered 3 and 10 mg/kg enoxaparin or isotonic saline solution. Twenty-four hours later, enoxaparin at 10 mg/kg greatly reduced infarct volume, decreased cell apoptosis in the cortex and obviously increased serum level of total antioxidant status. By contrast, administration of enoxaparin at 3 mg/kg did not lead to these changes. These findings suggest that enoxaparin exhibits neuroprotective effect on cold-induced traumatic brain injury in a dose-dependent manner

Potential Role of Plasma Myeloperoxidase Level in Predicting Long-Term Outcome of Acute Myocardial Infarction

We investigated the prognostic importance of plasma myeloperoxidase levels in patients with ST-elevation myocardial infarction (STEMI) at long-term follow-up, and we analyzed the correlations between plasma myeloperoxidase levels and other biochemical values

Cyberbullying among children and youth in Türkiye: A systematic review and meta-analysis

Problem: It has been reported in various studies that identifying risk and protective factors and outcomes of cyberbullying perpetration (CP) and cyberbullying victimization (CV) is crucial for educational strategies to fight against cyberbullying. The main purpose of the present study is to conduct a meta-analysis and systematic review to identify which risk and protective factors are more strongly associated with CP/CV and possible consequences of CP/CV among children and youth in Turkiye.Eligibility criteria: Various databases, including PubMed, Web of Science (WoS), ProQuest, ERIC, SCOPUS, Turkish Psychiatry Index, DergiPark, and National Dissertation/Thesis Center of Turkiye were searched to identify relevant studies.Sample: Fifty-nine studies met the inclusion criteria included in the present study.Results: Results revealed that the strongest risk factor was traditional bullying for CP (r = 0.47, p < .001) and traditional victimization for CV (r = 0.43, p < .001). The strongest protective factor was social skill for CP (r =-0.45, p < .001) and empathy for CV (r =-0.25, p < .001). In addition, involvement in CP behaviors had the strongest effect on negative self-concept (r = 0.28, p < .001), while exposure to CV on anxiety (r = 0.35, p < .001).Conclusions: Although this study has some limitations, the study's findings are important source of information for many professionals, such as pediatric nurses, school psychological counselors, psychologists, and policy makers to further educational strategies for children and young people in Turkiye.Implications: The study findings would be useful for developing educational programs to strengthen protective factors and reduce risk factors to prevent cyberbullying perpetration behaviors
