Published: January 2024

In the 1980s of the twentieth century, universities in developed countries began to realize the growing gap between the capabilities of new graduate engineers and the actual requirements of engineering branches. The strong progress of technology requires engineers to have the intellectual abilities and necessary job-specific skills to master that progress. This paper focuses on Conceive, Design, Implement and Operate (CDIO) approach-based teaching for students majoring in electrical and electronic engineering technology at engineering universities in Vietnam to demonstrate the feasibility of the teaching model. The experimental method of synthesizing qualitative and quantitative results for 90 students in control and experimental classes was used. The experimental and control classes both had 45 students. SPSS software version 22 was used to gather data and evaluate the learning results of the two experimental and control groups. According to the findings of the T-test analysis of the independent variables for the two groups, the experimental class performed better in academics and had students in the experimental group who were more satisfied with their post-test scores. This result contributes to confirm that the use of the CDIO-based teaching model in Vietnam is effective for students majoring in electrical and electronic engineering technology.

Published: January 2024

Masker adalah perlindungan pernafasan yang digunakan sebagai metode untuk melindungi individu dari menghirup zat-zat bahaya atau kontaminan yang berada di udara. Meskipun masker sangat diperlukan untuk menghindari penyebaran virus Corona, namun pembuangan masker mengancam lingkungan. Masker medis terdiri dari tiga lapisan, lapisan luar dan lapisan dalam adalah kain non-woven yang tahan air dan lapisan tengah adalah bahan yang meleleh. Sebagian besar, komposisi kimia dari masker medis adalah polipropilena. Pada review ini akan dibahas penggunaan limbah masker yang mengandung polipropilena sebagai bahan aditif dalam pembuatan campuran aspal. Metode yang digunakan adalah studi literatur dari peneliti terdahulu dan analisis penambahan limbah masker yang mengandung polipripilena yang berpengaruh terhadap campuran aspal. Sumber utama refrensi artikel ini berasal dari Research Gate, Science Direct, dan Google Scholar. Ditemukan bahwa unsur senyawa yang paling dominan pada masker medis adalah Si (Silika) sebesar 59,11%. Penambahan silika pada campuran aspal dapat meningkatkan ketahanan terhadap kerusakan alur, peningkatan nilai modulus, dan umur fatigue.

Published: January 2024

Abstract
This protocol provides an experimental model system to study bacterial competition in quasi-spherical three-dimensional bacterial colonies. To do so we encapsulate populations of two fluorescent Escherichia coli strains in inoculation droplets. The inoculation droplets grow when embedded in a hydrogel with nutrients and develop 3D colonies with well-defined sectors-like regions. The protocol can be extended and used with a wide range of different bacteria or – potentially – other cell types.

Authors: Lee Kiara , Pellowski Jennifer A. , Brayboy Lynae M. , Thompson Kathryn , Dunsiger Shira 
Published: January 2024

Abstract
Background
Hypertensive disorders of pregnancy are a leading cause of maternal mortality. Racial disparities in maternal outcomes such as maternal mortality in the United States (US) are well-documented, but the relationship of racism and/or discrimination with one’s risk of developing a hypertension during pregnancy (HDP) is not well-studied.
Methods
Data from 17 sites that asked questions regarding experiences with racism and/or discrimination during pregnancy via the Pregnancy Risk Assessment Monitoring System (PRAMS) Phase 8 (2016–2020) was used. Logistic regression models were used compare the potential of stress induced HDP from perceived experiences of racism and/or discrimination versus the effect of systemic racism and/or discrimination (in healthcare settings and generally) on racial disparities in HDP diagnosis.
Results
Among 9,907 live births, 18% of participants reported they were diagnosed with hypertension during pregnancy, with non-Hispanic Black individuals having the highest rate (21.8%). Regarding experiences of racism and/or discrimination, 76.4% of participants responded “yes”, with all races/ethnicities studied here except non-Hispanic White individuals responding “yes” at rates higher than 89%. Perceived experiences of racism and/or discrimination did not statistically significantly affect one’s odds of being diagnosed with HDP (OR = 0.94, CI: 0.74, 1.20). Non-Hispanic Black individuals did not have statistically significantly higher odds of having hypertension during pregnancy compared to non-Hispanic White individuals.
Conclusions
Experiences of racism and/or discrimination drive racial disparities in hypertensive disorders in pregnancy.
Public Health Implications:
It is vital to eliminate racist and discriminatory practices and behaviors to reduce maternal morbidity and mortality.
A discussion of a rationality and continuity related to Theta Functions by using the summation of Poisson
Authors: Louiz Akram 
Published: January 2024

Abstract
Mathematical philosophy is built by defining logical concepts such as the concept of infinity and the concept of continuity. Hence, mathematicians are not those who can calculate, but those who can understand the mathematical concepts and can develop them in order to make new mathematical findings or to transform an hypothesis into a philosophical truth. However, mathematicians are also alarmed scientists who can verify doubted formulas by disproving a mathematical proof or finding a counterexample. It is therefore false to think that mathematicians can’t surprise nowadays with new findings. This is a mathematical demonstration and discussion concerning a special case of functions related to Theta Functions and it is a logical opportunity for those who study the summation of Poisson. This work starts by using a formula of Poisson in order to make a mathematical representation for the studied function then a new approximation of this case of functions is demonstrated. Furthermore, we discuss the consequences if this studied function gives only irrationals as outputs then we use the definition of the continuity of real functions in order to make a demonstration for the continuity of the same Function. Finally, the lovers of mathematics are invited to understand the demonstrations of this article and the discussions of the continuity contradictions in order to develop new findings related to Theta Functions and the summation of Poisson

Abstract
Background: Internet addiction (IA) has been studied extensively and shown to have adverse social, psychological, and functional consequences. This has become a global health issue, particularly among young adults. Unfortunately, few studies have been conducted among medical students in Sudan. This study aimed to measure the prevalence of internet addiction and determine its associated risk factors among medical students.
Methods: This cross-sectional study was conducted among medical students using a systematic sampling technique. An online structured questionnaire was used, which included sociodemographic data and the Internet Addiction Test (IAT) to assess the presence and severity of IA, as well as the Kessler Questionnaire to assess psychological distress.
Results: Of 307 medical students participating in this study, 63.8% were female. The majority (78.5%) were aged 18–22 years, and the prevalence of internet addiction was 75.5% (n = 232). The Addiction levels were as follows: mild,39.7%; moderate, 33.2%; and severe, 2.6%. Multivariate regression analysis revealed that being a female medical student was associated with 1.9 times Internet addiction (OR = 1.87, p = 0.033). Psychological distress was associated with a 6.368-fold higher risk of internet addiction compared to non-distressed students (OR = 6.368, p = 0.000). Additionally, students in the clinical years had a lower risk of internet addiction, specifically the fourth and fifth years (OR = 0.325, p = 0.010; OR = 0.398, p = 0.043, respectively).
Conclusions: This study found a high prevalence of internet addiction among medical students at National University, which is strongly associated with mental distress. Effective awareness programs are required to educate students on limiting excessive internet usage and addressing associated risk factors. Future research should include longitudinal or multi-university studies to further investigate the relationship between internet addiction and mental distress in a robust manner.
Terminal Unfolded Protein Responses-related genes predict prognosis and associate with proliferation and apoptosis in clear cell renal cell carcinoma
Authors: Yang Riwei , Liang Leqi , Ao Shan , Chen Zugen , Chen Zude , Deng Tuo 
Published: January 2024

Abstract
Background
Terminal unfolded protein response (TUPR), a self-destruct mechanism of cells, initiates when irreversible endoplasmic reticulum stress (ER stress) occurs and causes cell apoptosis. Current studies show that TUPR also leads to apoptosis in carcinoma, which plays an indispensable role in development of tumors. However, understanding the specific role of TUPR in ccRCC cells is important for the treatment of tumors.
Methods
Based on 9 TUPR-associated genes, clusters of ccRCC patients were identified by unsupervised clustering. Prognostic models were constructed by LASSO regression and multivariate cox regression. Tunicamycin (Tm) was used to induce TUPR in ccRCC cells, and gene expression, proliferation, and apoptosis of ccRCC cells under TUPR were investigated by RT-qPCR, EdU and immunofluorescence staining respectively.
Results
ccRCC patients were distinguished into two clusters with various signatures. We confirmed that the TUPR-related prognostic model had a good predictive ability. 12 hours-Tm treatment induced TUPR in ccRCC cells and inhibited cell proliferation and promoted apoptosis. Silencing STT3B increased the sensitivity, inhibited the proliferation and promoted the apoptosis of ccRCC cells.
Conclusion
TUPR-associated genes were significantly correlated with clinical features of ccRCC patients, and were involved in ccRCC proliferation and apoptosis, which may become a new treatment option. STT3B may serve as a promising ccRCC therapeutic target.

Published: January 2024

Abstract
Background
Radiotherapy is one of the major local treatments for tumors. However, some complications may occur during the treatment, which includes radiation-induced heart disease (RIHD). However, there is no uniform standard for the prevention of RIHD currently. Dexmedetomidine is reported to have cardio protection effects, while its role in radiation-induced myocardial injury is unknown. In the current study, we aimed to evaluate the radioprotective effect of dexmedetomidine in X-ray radiation-treated mice.
Methods
9 male mice were randomized into 3 groups: control, 16Gy, and 16Gy + Dex. The 16Gy group was exposed to a single dose of 16Gy X-ray radiation. 16Gy + Dex group was pretreated with dexmedetomidine before X-ray radiation. The control group was treated with saline and did not receive X-ray radiation. The myocardial tissues were collected 16 weeks after X-ray radiation and subjected to hematoxylin-eosin (HE) staining, TUNEL staining, and immunohistochemistry (IHC) staining. Besides, we established a radiation-injured cardiomyocyte model. Cell viability was assessed with CCK-8 assay and cell apoptosis was assessed using flow cytometry. Protein expression of Bcl-2, Bax, LC3 I/II, Beclin-1, and p62 was detected through western blot assay.
Results
The results showed that 16Gy X-ray radiation resulted in significant changes in myocardial tissues, increased myocardial apoptosis, and activated autophagy. Pretreatment with dexmedetomidine significantly protects mice against 16Gy X-ray radiation-induced myocardial injury by inhibiting apoptosis and autophagy.
Conclusion
In summary, our study confirmed the radioprotective effect of dexmedetomidine against 16Gy X-ray radiation-induced cardiomyocyte apoptosis and autophagy activation.
