Oregano (Origanum vulgare) is an aromatic herb belonging to the Lamiaceae family. This study evaluated the therapeutic effect of oregano essential oil (OEO) on clinical bovine mastitis caused by Staphylococcus (S.) aureus and/or Escherichia (E.) coli. Thirty-two quarters from 18 lactating cows with subclinical mastitis were selected from a dairy farm and were divided into 4 groups (8 quarters/group): negative control (CON), positive control (GEN) and two OEO-treated groups (OEO-1 and OEO-2). Each group was intramammarily treated with saline, 10 g/tube of gentamicin ointment, and single and double doses of 0.9 mL OEO ointment twice a day for three days, respectively. After the treatments, physical udder conditions were greatly improved in GEN and OEO groups. In CON group, somatic cell counts (SCCs), number of white blood cells (WBC) and bacteria were increased. However, in OEO groups, SCCs and number of WBC were significantly decreased and S. aureus and E. coli were not detected in milk as compared with those before the treatments as well as GEN group. These results suggest that OEO may be a useful alternative to antibiotics for the control of subclinical bovine mastitis caused by S. aureus and/or E. coli.

Background: College students are recommended as the target groups for catch-up human papillomavirus (HPV) vaccination. Systematical exploration of awareness, acceptability, and decision-making factors of HPV vaccination among Chinese college students has been limited. Materials and Methods: A multi-center survey was conducted in mainland China between November 2011 and May 2012. College students aged 18-22 years were stratified by their grade, gender, and major for sampling. Socio-demographic and HPV-related information such as knowledge, perceptions, acceptability, and attitudes were collected through a questionnaire. Results: A total of 3,497 undergraduates completed the questionnaire, among which 1,686 were males. The acceptability of the HPV vaccine was high (70.8%). Undergraduates from high-level universities, at lower grade, or with greater prior knowledge of HPV vaccines showed higher acceptability of HPV vaccination ($p_{trend}$ <0.001). Additionally, undergraduates with vaccination experience outside the National Expanded Program on Immunization (OR=1.29; 95%CI: 1.10-1.51) or fear of HPV-related diseases (OR=2.79; 95%CI: 2.28-3.41) were more willing to accept HPV vaccination. General knowledge of HPV vaccine was low among undergraduates, and safety was a major concern (71.05%). The majority of students wished to pay less than 300RMB for HPV vaccine and chose the Chinese Center for Disease Control and Prevention as the most appropriate venue for vaccination. Conclusions: Although most undergraduates demonstrate positive attitudes towards HPV vaccination, challenges pertaining to introduction exist in China. Corresponding proactive education and governmental subsidy to do so are urgently needed by this age-group population. Suggestions and potential strategies indicated may help shape the future HPV vaccination program in China.

Several lines of evidence suggest that MUC5AC genetic polymorphisms might confer susceptibility to H. pylori infection and therefore gastric cancer risk. We here assessed the association of common polymorphisms in the MUC5AC gene with H. pylori seroprevalence using an LD-based tagSNP approach in a north-western Chinese Han population. A total of 12 tagSNPs were successfully genotyped among 281 unrelated ethnic Han Chinese who had no cancer history, and no identifiable gastric disease or genetic disease. No significant association between any alleles, genotypes or haplotypes and H. pylori seroprevalence was observed. Our results suggest that common genetic variations in MUC5AC gene might not make a major contribution to the risk of H. pylori infection.

It is desirable to monitor the vital signals, such as ECG, of a emergency patient during transfer in the hospital as well as in the ambulance. The purpose of this study is to develop a system which provides a real-time and wireless ECG to the medical staff nearby patient during transfer in hospital. In this context, we developed a low-power, low-cost and portable ECG system consisting of 1) ECG measurement and RF transmission module and 2) RF receiving and LCD display module. The developed system is expected to be useful in monitoring ECG of a patient during transfer in the hospital.

Objectives: Thirdhand smoke (THS) refers to residual tobacco smoke pollutants that remain after cigarette smoking. The purpose of this study was to determine predictors of the belief among adults in Korea that THS is harmful to children. Methods: A population-based sample of 3,000 adults (${\geq}19$ years) among a web-based panel in Korea was obtained in November 2016. The respondents filled out questionnaires, including THS beliefs, smoking status, presence of voluntary smoke-free rules at home, and support for the implementation of smoke-free regulations at home. THS beliefs were assessed with a statement that staying in a room today where people smoked yesterday can harm the health of children. Results: Overall, 92.2 % of adults believed that THS exposure could harm the health of children. Respondents who were nonsmokers, believed that SHS exposure were associated with pneumonia of children, lived in home with complete smoke-free rule at home, and supported the implementation of smoke-free regulation at home were more likely to believe that THS could harm for health of children. Conclusions: The majority of Korean adults believed that THS exposure could harm the health of children. Predictors identified in the study can be useful to address the risk of THS beliefs and promote implementation of tobacco control policies.

Emergency medical services (EMS) personnel are at high risk for adverse mental health outcomes during disease outbreaks. To support the development of evidence-informed mitigation strategies, we conducted a scoping review to identify the extent of research pertaining to EMS personnel's mental health during disease outbreaks and summarized key factors associated with mental health outcomes. We systematically searched three databases for articles containing keywords within three concepts: EMS personnel, disease outbreaks, and mental health. We screened and retained original peer-reviewed articles that discussed, in English, EMS personnel's mental health during disease outbreaks. Where inferential statistics were reported, the associations between individual and work-related factors and mental health outcomes were synthesized. Twenty-five articles were eligible for data extraction. Our findings suggest that many of the contributing factors for adverse mental health outcomes are related to inadequacies in fulfilling EMS personnel's basic safety and informational needs. In preparation for future disease outbreaks, resources should be prioritized toward ensuring adequate provisions of personal protective equipment and infection prevention and control training. This scoping review serves as a launching pad for further research and intervention development.

A comparative study of the dental health perception and dental health behaviors among 12,325 middle and high school students in urban and rural areas was conducted by using "2010 National Dental Health Investigation". The results of this study are as follows. For the dental health perception and the utilization of dental service, all middle and high school students had a low perception of the their dental health status toward the farming and fishing regions from the urban. For the time of tooth-brushing among the dental health behaviors, most middle and high school students brushed their teeth after lunch. In connection with the frequency of cariogenic snack intake, high school students had a greater percentage toward the farming and fishing regions from the urban. For the dental health status, middle school students in big cities had a high average of carious permanent teeth, but high school students had a high average of carious permanent teeth toward the farming and fishing regions from the urban. In other words, there was no significant difference in missing permanent teeth, filling permanent teeth and decay permanent teeth between middle school students by region, but high school students had a greater percentage of the dental health perception and dental health behaviors toward the farming and fishing regions from the urban, showing a little difference. Consequently, there was a relationship between middle and high school students' perception of dental health and their behaviors of dental health.

In this study, we have fabricated a fiber-optic radiation sensor using an organic scintillator for high energy electron beam therapy. The intensities of scintillating light from a fiber-optic radiation sensor are measured with different field size, electron beam energy and monitor unit of a clinical linear accelerator. To obtain percent depth dose(PDD), the amount of scintillating light is measured at different depth of polymethylmethacrylate(PMMA) phantom. Also the intensity of Cerenkov light is measured and characterized as a function of incident angle of electron beam and a subtraction method is investigated using a background optical fiber to remove a Cerenkov light.
