Abstract

This Article describes 3Dimention studies carried out of catalytic site  over the past year which have advanced of understanding the substrate to recognizition and how the catalytic mechanism of the several key DNAse I. The hydrolysis reaction that occurs in DNASe I is influenced by Mg 2+ and Ca 2+ but let the Binding of DNASe I ions is still unclear, the active side is found, the amount and mechanism of Ca2+ and Mg2+ . The results of the review in this article indicate that DNASe I is needed externally from experimental animals and simulations improve the binding reaction of Ca 2+ and Mg 2+ which is supported by some literature that uses crystallographic studies where Ca 2+ ions can stabilize DNASe I and also in the presence of Mg 2+ ions that can accelerate the hydrolytic failure of the cation. The results of the review explain the role of cations collectively electrostatic matching between DNASe I and DNA.

Abstract

This community service aims to increase students' awareness, understanding, and skills in maintaining mental health through education and counseling programs. Student life is often filled with academic, social, and adaptable pressures to a new environment that can trigger mental health problems such as stress, anxiety, and depression. The program includes seminars, workshops, and counseling sessions held at several colleges with a focus on introducing the importance of mental health, coping techniques, and appropriate psychological support. This activity involves students' active participation in discussions, role-plays, and simulations, which helps them better understand how to manage emotions and seek help when facing problems. The evaluation of the program showed an increase in students' knowledge and skills in dealing with mental health problems, as well as an increase in the number of students willing to access counseling services. Through this activity, it is hoped that a campus environment that is more supportive of mental health and reduces the stigma of seeking professional help.

Abstract

This study aims to examine the relationship between the frequency of independent anatomy study and anatomy block exam results among undergraduate medical students. The data analysis revealed a positive and significant correlation between the two variables, with a Pearson correlation coefficient of r = 0.684, indicating a strong relationship. Furthermore, the simple linear regression analysis showed that each increase in the level of independent study frequency contributed to a 4.82-point increase in the anatomy block exam score. These findings suggest that the more frequently students engage in independent anatomy study, the more likely they are to achieve better academic outcomes in anatomy courses

Abstract

Cardiovascular health is a critical aspect of overall well-being, particularly among medical students who often experience high levels of academic stress. Persistent stress has been shown to influence autonomic function, elevate blood pressure, and disrupt heart rate variability (HRV), thereby increasing the risk of early cardiovascular dysfunction. This study aims to examine the relationship between stress levels and cardiovascular health parameters—specifically blood pressure, resting heart rate, and body mass index (BMI)—among medical students at Universitas Imelda Medan. Using a cross-sectional design, data were collected through standardized stress questionnaires and physiological measurements. The findings are expected to demonstrate a significant association between higher stress levels and adverse cardiovascular indicators. Understanding this relationship may contribute to the development of preventive strategies and stress management interventions within medical education settings. Ultimately, this study highlights the importance of promoting mental well-being and healthy lifestyle practices to protect cardiovascular health in young adult populations.
