Purpose: The present study attempted to explore the effects of different tempos of piano music on heart rate and autonomous nervous system during the recovery period after high-intensity exercise. In addition, the study analyzed the influence of different tempos on the recovery period of athletes to devise methods for accelerating fatigue recovery through piano music.

Method: A total of 57 college students majoring in physical education were selected as experimental subjects and were divided into three groups, namely Lento group (n = 20), Moderato group (n = 20), and Allegretto group (n = 20; only 17 students completed the experiment).

In sports, because the movement of the human body is composed of the movements of the human limbs, and the complex and changeable movements of the human limbs lead to various and complicated movement modes of the entire human body, it is not easy to accurately track the human body movement. The recognition of human characteristic behavior belongs to a higher level computer vision topic, which is used to understand and describe the characteristic behavior of people, and there are also many research difficulties. Because the radial basis fuzzy neural network has the characteristics of parallel processing, nonlinearity, fault tolerance, self-adaptation, and self-learning, it has the advantage of high recognition efficiency when it is applied to the recognition of intersecting features and incomplete features.

Novel Anti-Angiogenic and Anti-Tumour Activities of the N-Terminal Domain of NOEY2 via Binding to VEGFR-2 in Ovarian Cancer.

Biomol Ther (Seoul)

September 2021

BK21 FOUR Team and Integrated Research Institute for Drug Development, College of Pharmacy, Dongguk University, Seoul 10326, Republic of Korea.

The imprinted tumour suppressor NOEY2 is downregulated in various cancer types, including ovarian cancers. Recent data suggest that NOEY2 plays an essential role in regulating the cell cycle, angiogenesis and autophagy in tumorigenesis. However, its detailed molecular function and mechanisms in ovarian tumours remain unclear.

In this paper, a deep confidence neural network algorithm is used to design and deeply analyze the risk warning model for stadium operation. Many factors, such as video shooting angle, background brightness, diversity of features, and the relationship between human behaviors, make feature attribute-based behavior detection a focus of researchers' attention. To address these factors, researchers have proposed a method to extract human behavior skeleton and optical flow feature information from videos.

  • * During this inactive phase, the blood-testis barrier (BTB) loses its integrity, causing developing germ cells to either be engulfed by Sertoli cells or slough off, leading to the absence of sperm in most epididymis regions.
  • * Key genes responsible for tight junctions in the BTB (like claudin-11 and occludin) are present in active testes but not in inactive ones, indicating that structural disorganization of the BTB is linked to testicular regression and the removal of germ

This present study aims to investigate factors that impact behavioural intention of university students on e-learning use during the COVID-19 pandemic. An online questionnaire was utilised to gather data from 109 students enrolled in one of the universities in Indonesia. The Technology Acceptance Model (TAM) was the primary framework employed for analysis, in which system quality and e-learning experience were included as external constructs to seek out a much better model to improve the understanding of students' intention to adopt e-learning.

  • Melatonin has been shown to cause testicular regression in seasonal breeding animals, particularly in male Syrian hamsters when injected in the afternoon.
  • A study examined the effects of different dosages of melatonin given daily via gavage on hamsters kept in long and short photoperiods over 8 weeks.
  • Results indicated that higher doses of melatonin led to significant testicular shrinkage compared to controls, with low doses having no adverse effect, similar to the large testes seen in the long photoperiod control group.

Article Synopsis
  • Spermatogonial stem cells (SSCs) have unique characteristics that allow them to develop into gametes, undergoing significant changes in gene expression during spermatogenesis.
  • The process includes phases like gene repression and chromatin modifications, ultimately leading to the formation of fertilization-ready spermatozoa.
  • Recent research highlights the roles of transcription factors YY1 and CP2c in regulating spermatogenesis and stemness, providing insights into their interactions during specific stages of sperm development.

  • - The study built on previous findings indicating that low-dose nonylphenol (NP) exposure negatively impacts the reproductive health of female mice, specifically looking at its effects on their reproductive organs.
  • - Mice were exposed to NP from before mating until their offspring were 33 days old, with significant findings such as early vaginal opening and differences in tissue weights related to NP exposure.
  • - Pathohistological analysis revealed changes in ovarian follicle numbers and uterine structure, suggesting that NP exposure leads to early puberty and reproductive abnormalities, prompting the need for further research to clarify NP's effects and mitigate risks.

IRF-1 Inhibits Angiogenic Activity of HPV16 E6 Oncoprotein in Cervical Cancer.

Int J Mol Sci

October 2020

Phamaceutical Biochemistry, College of Pharmacy and Integrated Research Institute for Drug, Dongguk University, Goyang 100-715, Korea.

HPV16 E6 oncoprotein is a member of the human papillomavirus (HPV) family that contributes to enhanced cellular proliferation and risk of cervical cancer progression via viral infection. In this study, interferon regulatory factor-1 (IRF-1) regulates cell growth inhibition and transcription factors in immune response, and acts as an HPV16 E6-binding cellular molecule. Over-expression of HPV16 E6 elevated cell growth by attenuating IRF-1-induced apoptosis and repressing p21 and p53 expression, but activating cyclin D1 and nuclear factor kappa B (NF-κB) expression.

The purpose of the present study was to investigate the effects of cold exposure discontinuation on local cold tolerance of older retired female haenyeos in Korea. A total of 30 older women participated in this study: older retired haenyeos (89 ± 4 y in age, N = 10), active haenyeos (current divers) (75 ± 4 y, N = 10), and age-matched non-divers (75 ± 6 y, N = 10). Our criterion for local cold tolerance was cold-induced vasodilation (CIVD) of the finger.

  • The study investigates the relationship between moderate-to-vigorous physical activity (MVPA) and television watching on cardiorespiratory fitness in young Asian adolescents, an area with limited research.
  • Conducted among 9,553 adolescents aged 12-15 from eight Asian cities, the research utilized the PACER test for fitness assessment and the International Physical Activity Questionnaire to gauge MVPA and TV time.
  • Results showed that higher levels of MVPA (≥60 min/day) significantly improve fitness scores, even if adolescents watch more TV, while less active girls who watched less TV had better fitness than those in the most sedentary group.

Purpose: There is a growing number of older adults moving into assisted-living facilities to maintain their independence while being assisted with certain tasks and having convenient access to services. Physical activity (PA) and vitality play an important role in independence, as well as in mental health, of older adults. However, no research has examined the difference in older adults' levels of vitality (defined as the state of feeling alive and alert) between those living in assisted-living facilities and those from community-living settings.
