Lettuce (Lactuca sativa L.) is a member of the family Compositae (Asteraceae). This plant, which is grown for its leaves, is grown in open field and greenhouse conditions almost everywhere in the world and in Turkey. With the present study virus diseases of lettuce and their prevalence in Konya province was revealed for the first time. For this purpose, leaf samples were taken from lettuce plants showing virus diseases symptoms with surveys carried out in Konya province lettuce planting areas from May to August in 2020. Then the collected lettuce leaf samples were tested in laboratory conditions by Double Antibody Sandwich Enzyme-linked Immunosorbent Assay (DAS-ELISA) method to reveal infections of Cucumber mosaic virus (CMV), Miraflori lettuce big vein virus (MiLBVV), Lettuce mosaic virus (LMV), and Tomato spotted wilt virus (TSWV). According to the information obtained from the results of the study, it was determined that 40 out of 97 (41.23%) lettuce plant samples and all (6) weed samples were infected with at least one of the viruses. In lettuce leaf samples; TSWV (27.83%), LMV (12.37%), CMV (10.31%) and MiLBVV (5.15%) infections have been detected. In weed samples; infections of CMV (83.33%), LMV (66.66%), and TSWV (50%) have been revealed. The infections of TSWV, LMV, CMV, and MiLBVV on lettuce plants in Konya province were reported firstly with the study.

Abstract Background The annual economic loss caused by plant viruses exceeds 10 billion dollars due to the lack of ideal control measures. Quercetin is a flavonol compound that exerts a control effect on plant virus diseases, but its poor solubility and stability limit the control efficiency. Fortunately, the development of nanopesticides has led to new ideas. Results In this study, 117 nm quercetin nanoliposomes with excellent stability were prepared from biomaterials, and few surfactants and stabilizers were added to optimize the formula. Nbhsp70er-1 and Nbhsp70c-A were found to be the target genes of quercetin, through abiotic and biotic stress, and the nanoliposomes improved the inhibitory effect at the gene and protein levels by 33.6 and 42%, respectively. Finally, the results of field experiment showed that the control efficiency was 38% higher than that of the conventional quercetin formulation and higher than those of other antiviral agents. Conclusion This research innovatively reports the combination of biological antiviral agents and nanotechnology to control plant virus diseases, and it significantly improved the control efficiency and reduced the use of traditional chemical pesticides.

AbstractThe effect of respiratory infectious diseases on STEMI incidence, but also STEMI care is not well understood. The Influenza 2017/2018 epidemic and the COVID-19 pandemic were chosen as observational periods to investigate the effect of respiratory virus diseases on these outcomes in a metropolitan area with an established STEMI network. We analyzed data on incidence and care during the COVID-19 pandemic, Influenza 2017/2018 epidemic and corresponding seasonal control periods. Three comparisons were performed: (1) COVID-19 pandemic group versus pandemic control group, (2) COVID-19 pandemic group versus Influenza 2017/2018 epidemic group and (3) Influenza 2017/2018 epidemic group versus epidemic control group. We used Student’s t-test, Fisher’s exact test and Chi square test for statistical analysis. 1455 patients were eligible. The daily STEMI incidence was 1.49 during the COVID-19 pandemic, 1.40 for the pandemic season control period, 1.22 during the Influenza 2017/2018 epidemic and 1.28 during the epidemic season control group. Median symptom-to-contact time was 180 min during the COVID-19 pandemic. In the pandemic season control group it was 90 min (p = 0.183), and in the Influenza 2017/2018 cohort it was 90 min, too (p = 0.216). Interval in the epidemic control group was 79 min (p = 0.733). The COVID-19 group had a door-to-balloon time of 49 min, corresponding intervals were 39 min for the pandemic season group (p = 0.038), 37 min for the Influenza 2017/2018 group (p = 0.421), and 38 min for the epidemic season control group (p = 0.429). In-hospital mortality was 6.1% for the COVID-19 group, 5.9% for the Influenza 2017/2018 group (p = 1.0), 11% and 11.2% for the season control groups. The respiratory virus diseases neither resulted in an overall treatment delay, nor did they cause an increase in STEMI mortality or incidence. The registry analysis demonstrated a prolonged door-to-balloon time during the COVID-19 pandemic.

The elderly (elderly) is one of the groups that are susceptible to being infected with Corona Virus Diseases 19 (Covid 19). Therefore, the elderly group is a priority group to get the Covid 19 vaccination. This study aims to describe and analyze the scope of the implementation of the COVID-19 vaccination program for the elderly in the Cijayanti Health Center work area which is still low. This research is a descriptive study with a qualitative approach. Data collection was carried out by in-depth interviews with midwives as the holder of the immunization program as the main informant, the doctor as the head of the vaccinator team, the holder of the elderly program, the Cijayanti, and Bojong Koneng village offices, and 10 elderly people. The achievement of the elderly vaccination at the Cijayanti Health Center was only 10.8% of the total number of elderly people. There are several obstacles in collecting data on elderly who are willing to be vaccinated because of the influence of the environment, both from their immediate family/children and from the surrounding community. Environmental factors, namely family support, community leaders, religious leaders greatly influence the participation of the elderly in covid vaccination 19.

At the end of 2019 a new virus was discovered which is now an infectious disease outbreak around the world and WHO (World Health Organization) gives the name of the virus that is currently endemic as Covid-19 (Corona Virus Diseases 2019). This research is a qualitative research that aims to collect in-depth data from sources or informants by conducting direct interviews. The number of informants in this study were 10 people. The data collection is done by direct observation to field conducted in-depth interviews of workers and equipped with recording equipment sound made to 10 informants. The results of the research carried out are that there are workers who have not been able to carry out and implement health protocols in accordance with the recommendations of the government. Of the several health protocols that exist at the Slaughter Goat Research Workshop, there are health protocols that have been violated by workers, namely all workers do not wear masks when in the work environment, the absence of workers who apply physical or social distancing during work or during rest hours, water and hand washing soap are not provided and hand sanitizers are never used and are only for display in the office, and workers believe that it is impossible for fellow workers to transmit the Covid-19 virus to fellow workers although there are already some workers in Loka Penelitian Kambing Potong who have contracted the virus, they are not worried and are not afraid of it. The advice that can be given is that workers must be aware of the importance of implementing health protocols and Loka Penelitian Kambing Potong should provide guidance and direction to workers in an effort to suppress the decline in Covid-19 cases
