Prolonged Viability of Senecavirus A in Exposed House Flies (Musca domestica)

House flies (Musca domestica) are often present in swine farms worldwide. These flies utilize animal secretions and waste as a food source. House flies may harbor and transport microbes and pathogens acting as mechanical vectors for diseases. Senecavirus A (SVA) infection in pigs occurs via oronasal route, and animals shed high virus titers to the environment. Additionally, SVA possesses increased environmental resistance. Due to these reasons, we investigated the tenacity of SVA in house flies. Five groups of flies, each composed of ten females and ten males, were exposed to SVA, titer of 109.3 tissue culture infectious dose (TCID50/mL). Groups of male and female flies were collected at 0, 6, 12, 24, and 48 h post-exposure. For comparison purposes, groups of flies were exposed to Swinepox virus (SwPV). Infectious SVA was identified in all tested groups. Successful isolation of SVA demonstrated the titers varied between 106.8 and 102.8 TCID50/mL in female groups and varied from 105.85 to 103.8 TCID50/mL in male groups. In contrast, infectious SwPV was only detected in the female group at 6 h. The significant SVA infectious titer for prolonged periods of time, up to 48 h, indicates a potential role of flies in SVA transmission.

The Status of First Aid Skills Mastery and Training Preferences of College Students: A Cross-Sectional Survey

Objective： Bystander first aid can improve the survival rate after out-of-hospital cardiac arrest or trauma, College students are potential bystanders of first aid in society. In the research, we aim to determine the universality of first aid training and the mastery of first aid skills among college students in order to implement first aid. Methods：From January to October 2021, Carry out questionnaire surveys by WeChat push, A random cross-sectional study was conducted on students from five universities in Wenzhou. In order to understand the knowledge and skills of first aid, Respondents accepted the first aid scenario that answered two hypotheses. Results：Among the 1,171 college students interviewed. Among them, 37.23% are males and 62.77% are females; 78.31% have first aid training experience, and 21.69% have no first aid training experience; 71% of college students acquire theoretical knowledge and practical skills through first aid training conducted by the Red Cross, medical emergency centers or hospitals, etc. 22% of college students study through the information network; All college students interviewed expressed their willingness to participate in first aid training. But 21.69% of college students have not received first aid training, The reason for the inability to participate in the training is that they do not understand the ways to participate in first aid training, accounting for 37.01%; Lack of confidence accounted for 19.69%, and lack of time accounted for 35.04%; In the hypothetical emergency scene, In the male group, 48.96% were willing to treat the injured, and 36.19% in the female group. There is a statistical difference between the two (P＜0.01); The junior college student group and the undergraduate student group are 28.09% and 44.09% separately. The medical professional group and the students with the first aid training group are 60.4% and 43.51% separately, The willingness to implement first aid has a clear advantage over the non-medical and non-trained two groups. The comparison between the two groups was statistically significant (P <0.01). The first aid skills are well mastered: chest compression 46.19%, judgment awareness 35.95%, hemostasis bandaging 32.88%, The worse ones were artificial respiration 24.67%, open airway 23.56%, and fracture fixation 8.96%. Conclusion: College students have a positive attitude towards learning first aid knowledge. However, it was found that the first aid skills were not well mastered, and the training was insufficient. Colleges and universities should provide first aid-related courses, extracurricular intensive training and other methods, Increase the knowledge of college students to deal with emergencies and improve basic first aid skills. Incorporating first aid skills training into university curricula and implementing it is a long-term strategy. Improve college students' awareness of first aid knowledge to obtain better social benefits. Key words: Attitude, First aid skills, college student training.

Vocal Acoustic Analysis

Vocal acoustic analysis is becoming a useful tool for the classification and recognition of laryngological pathologies. This technique enables a non-invasive and low-cost assessment of voice disorders, allowing a more efficient, fast, and objective diagnosis. In this work, ANN and SVM were experimented on to classify between dysphonic/control and vocal cord paralysis/control. A vector was made up of 4 jitter parameters, 4 shimmer parameters, and a harmonic to noise ratio (HNR), determined from 3 different vowels at 3 different tones, with a total of 81 features. Variable selection and dimension reduction techniques such as hierarchical clustering, multilinear regression analysis and principal component analysis (PCA) was applied. The classification between dysphonic and control was made with an accuracy of 100% for female and male groups with ANN and SVM. For the classification between vocal cords paralysis and control an accuracy of 78,9% was achieved for female group with SVM, and 81,8% for the male group with ANN.

On Contemporary Female Seal-carving Artists

In contemporary times, female art is gradually seen as an independent branch of art. Seal carving is a world intangible cultural heritage and an important part of Chinese art. Female seal-carving artists, against such a backdrop, are exhibiting their own charm with a tint of Chinese characteristics. This paper intends to give an outline of female seal carving in China and its development process. It then explores its artistic features with examples of contemporary female seal-carving artists, such as Luo Pengpeng and Yin Fenghua. In the end the problems confronting the female group will be discussed and their way out.

Association Between Bedtime at Night and Systolic Blood Pressure in Adults in NHANES

Objectives: This study aimed to explore the association between bedtime at night and systolic blood pressure (SBP) in adults.Methods: We conducted a cross-sectional study composed of 7,642 individuals from the National Health and Nutrition Examination Survey (NHANES). Bedtime was defined as the response to the question: “What time do you usually fall asleep on weekdays or workdays?” SBP was taken using the average of all measured values. Multiple linear regression analyses were done to explore the relationship between bedtime and SBP.Results: The bedtime was changed from categorical variable to continuous variable for data analysis, and a significantly negative association was identified between bedtime and SBP (β, −0.23 [95% CI, −0.43, −0.02]). With the delay of bedtime, the SBP showed a gradual decrease trend, and it was dropped to the lowest at 0:00. After 0:00, the SBP was gradually increased with the delay of sleep time. The stratified analyses showed that in the female group, with the delay of bedtime, the range of SBP was decreased more obviously at 0:00. In the 18–45 year group, bedtime had little effect on SBP. Among ≥45 years old group, this trend was still the same. In the black group, an obvious downward trend was found at 22:00.Conclusion: With the delay of bedtime, the SBP had shown a gradual decrease trend, and it was dropped to the lowest at 0:00. After 0:00, the SBP was gradually increased with the delay of sleep time. Bedtime and SBP showed a U-shaped relationship.

Comparison of Timing to Develop Anti-Drug Antibodies to Infliximab and Adalimumab Between Adult and Pediatric Age Groups, Males and Females

OBJECTIVE To compare the timing of serum anti-drug antibodies in adult and pediatric age groups, males and females, treated for inflammatory bowel disease or arthritis with adalimumab or infliximab by retrospectively combining data collected during a 2-year therapeutic drug monitoring period. METHODS Four hundred thirty sera were divided in groups collected at 0, 3, 6, 12, and 24 months (T0, T3, T6, T12, and T24) after initiation of therapy and assayed for drug and relative anti-drug antibodies levels. At each time point, the percentage of sera presenting anti-drug antibodies, as well as the drug concentrations, were calculated and correlated with patient age and sex. RESULTS Anti-drug antibodies were present in 31.5% of sera and were significantly higher in the pediatric age group than in the adult age group, through all time points. The percentages of sera showing anti-drug antibodies were significantly different as early as 3 months and were sera from pediatric female group. The percentages of sera showing anti-drug antibodies reached the highest value at 6 months in the pediatric age group and at 12 months in the adult age group. CONCLUSIONS Sera from pediatric had an earlier presence of anti-drug antibodies than adults. In particular, pediatric females sera showed the fastest anti-drug antibodies development.

Clinical evidence in the phenomenon of Alien Abduction

Purpose: Starting from the classic definition of “alien abduction”, the present research, starting from the study published in 2020 on the proposed clinical classification of this particular phenomenon, is aimed at confirming the theoretical assumption of psychopathological origin. Methods: Clinical interview, based on narrative-anamnestic and documentary evidence and the basis of the Perrotta Human Emotions Model (PHEM) concerning their emotional and perceptual-reactive experience, and administration of the battery of psychometric tests published in international scientific journals by the author of this work: 1) Perrotta Integrative Clinical Interviews (PICI-2), to investigate functional and dysfunctional personality traits; 2) Perrotta Individual Sexual Matrix Questionnaire (PSM-Q), to investigate the individual sexual matrix; 3) Perrotta Affective Dependence Questionnaire (PAD-Q), to investigate the profiles of affective and relational dependence; 4) Perrotta Human Defense Mechanisms Questionnaire (PDM-Q), to investigate the defence mechanisms of the Ego. Results: Preliminary results from the interviews and the anamnestic form would suggest that the phenomenon of alien abductions has a greater tendency to occur in the female group, in the adult and mature group (and tends to diminish but not disappear with advancing age) and in the group geographically originating in central-northern Italy (due to lower religious influences but greater openness to the typical contents of ufological and mystery narratives). Moreover, the subsequent results would lead us to deduce with almost total certainty, concerning the selected sample, that the phenomenon of alien abductions has an absolute prevalence in the believing population concerning the existence of paranormal phenomena per se, even in the absence of objective and/or scientific evidence. It is a phenomenon that is almost completely linked (110/112, 98.2%) to a medium-low or not fully educated cultural level. Based on the PICI-2 it emerged that the primary emerging disorder is alternatively the delusional disorder, the dissociative disorder and the narcissistic disorder; followed, as secondary disorders, by the delusional disorder (if it is not considered as primary disorder), the schizoid disorder, the borderline disorder, the obsessive disorder and the psychopathic disorder. The analysis of functional traits also reported the marked dysfunctional tendency of the classes referring to self-control, sensitivity, Ego-Es comparison, emotionality, ego stability, security and relational functionality, confirming here too the marked dysfunctional tendency of the clinical population. According to the PSM-Q, almost 2/3 of the participants (73/112, 65.2%) present a dysfunctional tendency to sexual behaviour and a marked tendency to chronicle feelings of shame in avoidance behaviour or hyposexuality. Furthermore, 100% of the sample of the population surveyed report having suffered significant or serious psychological or physical abuse at a young age, or intra-parental relational imbalances, or in any case a sexual upbringing that was not open and lacking in free communication. According to the PDM-Q, 27.7% (31/112) are affected by affective dependency, with greater emphasis on types I (neurotic), VI (covert narcissist), V (borderline) and III (histrionic), in that order of descent. Finally, the PDM-Q reveals the widespread psychopathological tendency of the functional ego framework for the mechanisms of isolation, denial, regression, reactive formation, denial, projection, removal, withdrawal, instinct, repression and idealisation. Conclusion: This research confirms the psychopathological nature of the alien abduction phenomenon, which deserves to be treated using a psychotherapeutic approach (preferably cognitive-behavioural and/or strategic) and possibly also pharmacological in serious cases, depending on the symptoms manifested and the severity of the morbid condition.

Barriers to Career Advancement in the Hotel Industry in Timor-Leste: Study of Gender Stereotyping, Old Boys’ Network and Gender Differences

The hotel industry in Timor-Leste is female-dominated. However, women are under-represented in managerial and senior executive positions. This study examines the relative importance of gender stereotyping and old boys’ network variables as barriers that impact women’s and men’s career advancement in the hotel industry in Dili, Timor-Leste. A survey questionnaire was distributed at 20 hotels in Dili, Timor-Leste, and 16 hotels granted approval, represented by 385 individuals (226 women and 159 men). These data were analyzed using structural equation modeling. The results from this study indicated that gender stereotyping had a significant influence as a barrier to career advancement. Old boy’s network had no significant barrier to the career advancement for both in women versus men comparison. Furthermore, the male group scores higher than the female group in the variables of stereotyping in gender differences analysis as the higher scores represent the biases against women. This study is the first study to examine barriers for individuals’ career advancement in the hotel industry of Dili, Timor-Leste. This study suggests theoretical and practical implications on barriers for men’s and women’s career advancement and mitigates gender inequality in the organization.

The Influence of Practical Curricular Courses on the Upper Body Flexibility in the Faculty of Physical Education and Sports Students

The range and quality of sports technique is conditioned by flexibility. This study analyzes the effects of practical activities that are specific to the first year FPES Galati courses on the upper body flexibility. Over the course of the academic year 2017-2018, the investigated group (composed of 27 girls and 46 boys) has constantly participated for 28 weeks in the 6 practical courses (gymnastics, track and field, swimming, football, volleyball, ice skating), divided in a balanced way throughout the two semesters. The analysis and comparison of the results for the two sexes, during the initial and final tests, applied at the beginning and the end of the academic year, show a superiority of the girls' flexibility in almost all events. The Wilcoxon test for paired samples has identified significant progress between the initial and final assessments in the female group, in 4 of the tests (Right lateral trunk flexibility Combined spine-hip flexibility, Shoulder flexibility, Vertical arm flexibility), recording Z values corresponding to thresholds of P<0.05; however, in the male group, no significant progress was recorded not even in one of the tests, all Z values corresponding to thresholds of P>0.05. The investigation of the differences recorded between independent samples, using the Mann Whitney U test, has identified significant increases in the girls' values in only 3 events, during the initial tests, and in 4 during the final ones, even if the girls' average values are higher than the boys' values for most tests. In conclusion, the boys did not record significant improvements in their performances, only a slight increase or the same values over the course of the investigated period; the girls however, recorded results that show a potential of optimizing their flexibility at this age. The authors recommend that an increased attention should be given during practical courses to develop the students' flexibility as a favoring factor of motion fluidity and improvement of the students' motor potential.
