Purpose:
The purpose of this study was to investigate the effect of motivational regulation strategies (MRSs) on cognitive learning and academic performance.
Methods:
The participants were a total of 510 pre-medical and medical students. Survey instruments assessed the use of MRSs and cognitive learning strategies. Students’ grade point averages were used for academic performance. Structural equation modeling was used to analyze data, using Mplus ver. 7.4 (Muthén & Muthén, Los Angeles, USA).
Results:
Confirming the measurement model validity, the results of structural model indicated the followings: (1) MRSs had a significant impact on cognitive learning, while these strategies negatively affected academic performance; (2) cognitive learning significantly influenced academic performance and mediated the effect of MRSs on academic performance; and (3) only academic levels had a significant effect on cognitive learning.
Conclusion
The findings from this study confirmed that MRSs were highly influential to predicting students’ cognitive learning which affects their better learning performance. Thus, instructional design and practice to support learning motivation is needed to promote cognitive learning and training programs to practice the effective methods of using MRSs in learning need to be provided.

Due to the coronavirus disease 2019 pandemic, the new norm of online learning has been recognized as core to medical institutions for academic continuity, and students are expected to be motivated and engaged in learning while maintaining distance from other peers and educators. To facilitate students’ and educators’ newly defined roles in online medical education settings, it is crucial to understand how students are actively motivated and engaged in learning. Hence, this study explored medical students’ motivational regulation profiles and examined the effects of motivational regulation strategies (MRS) on cognitive learning and learning engagement for online learning. Data were collected after the end of the first semester in 2020 from a sample of 334 medical students enrolled at a public university school of medicine. Latent profile analysis indicated three subgroups with different motivational regulation profiles: the low-profile, medium-profile, and high-profile groups. Regarding different MRS patterns in the high-profile group, mastery self-talk, performance approach self-talk, and the self-consequating strategy appeared to be most applicable for regulating learners’ motivation. Analysis of variance showed that the profile groups with higher levels of MRS use were connected to a higher willingness to use cognitive learning strategies and a higher degree of engagement in online learning. The findings of this study emphasize the use of specific sets of MRS to support learning motivation and the need to design effective self-regulated learning environments in online medical education settings.

OBJECTIVE: The fragile histidine triad (FHIT) gene is located at chromosome 3p14.2 and encompasses the common fragile site, FRA3B, which may contribute to chromosome breakage and rearrangement of cancer cells. In this study, we examined whether transcriptional alterations of FHIT gene play a role in the development of human cervical carcinomas and the possibility that hypermethylation of CpG islands serves for FHIT inactivation. We then analyzed FHIT expression status with clinical parameters to determine whether it has any prognostic significance. METHODS: The study group included 50 squamous carcinomas, 4 adenocarcinomas, 4 adenosquamous carcinomas, 7 noncancerous tissue and the clinical stage is composed of 4 Ia, 37 Ib and 17 II. Tissue specimens were snap-frozen in liquid N2 and stored at -70degrees C until used. To examine for abnormal transcripts of the FHIT gene, quantitative RT-PCR, genomic DNA-PCR and nonisotopic RT-PCR-SSCP analysis were performed using the standard method. The methylation status was determined by methylation specific PCR. RESULTS: The FHIT gene was down-regulated in 15 of 58 (25.9%) cervical carcinomas. FHIT promoter hypermethylation was detected in 15 of 15 (100%) abnormally expression in cervical carcinomas. CONCLUSION: In this study, gene mutation is not a main mechanism for FHIT inactivation, but the aberrant promoter hypermethylation may be correlated with decreased expression of the FHIT gene. The significance of decreased expression of FHIT does not appear to be an independent prognostic factor in cervical cancers, although a still larger sample of patients will be required to asses this issue definitively.

Background:
and Purpose: Ventricle enlargement has been implicated in the pathophysiology of Alzheimer’s disease (AD). We studied the relationship between ventricular size and cognitive function in patients with AD. We focused on the effect of the initial ventricle size on the rate of cognitive decline in patients with AD.
Methods:
A retrospective analysis of probable clinical AD participants with more than 2 magnetic resonance imaging images was performed. To measure ventricle size, we used visual rating scales of (1) Cardiovascular Health Study (CHS) score and (2) conventional linear measurement method.
Results:
Increased clinical dementia rating (CDR) was correlated with a decreased MiniMental Status Examination (MMSE) score, and increased medial temporal lobe atrophy (MTLA) and global ventricle size (p<0.001, p<0.001, p=0.021, respectively). There was a significant correlation between the change in cognitive function in the group (70%–100%ile) with a large initial ventricle size (p=0.021 for ΔCDR, p=0.01 for ΔMMSE), while the median ventricle size (30%–70%ile) showed correlation with other brain structural changes (MTLA, frontal atrophy [FA], and white matter) (p=0.036 for initial MTLA, p=0.034 for FA).
Conclusions
In this study, the initial ventricle size may be a potential new imaging biomarker for initial cognitive function and clinical progression in AD. We found a relationship between the initial ventricle size and initial AD-related brain structural biomarkers.

Malignant mixed mullerian tumor of the ovary are very aggressive tumors that were usually diagnosed at an older age. They are usually at an advanced stage at the time of diagnosis, and survival after diagnosis varies by stage of disease and histological type. Despite aggressive treatment that includes surgery and chemotherapy, women with these tumors have a significantly increased risk of death giving them a very poor prognosis. The poor prognosis associated with this rare disease represents a need to new therapeutic regimens to improve patients' survival. We experienced two cases of primary malignant mixed mullerian tumor of the ovary.

PURPOSE: The aim of our study was to compare the efficacy and safety of ibuprofen and indomethacin in the prophylaxis of patent ductus arteriosus (PDA) in preterm infants and to determine whether ibuprofen could be an alternative agent in prophylactic use. METHODS: A retrospective study including 37 preterm infants <1,500 g of birth weight, <34 weeks of gestation, whom were administrated indomethacin (n=17; January 2009-December 2009) or ibuprofen (n=20; January 2010-February 2011) within 24 hr after birth was conducted. The rate of ductal closure, need for surgical ligation, clinical outcomes such as necrotizing enterocolitis, intraventricular hemorrhage, bronchopulmonary dysplasia, retinopathy of prematurity (ROP) and death rate were compared. RESULTS: There were no statistically significant differences between the two groups in mean gestational age, mean birth weight, Apgar score, sex, type of delivery, maternal dexamethasone treatment, frequency and duration of ventilator and surfactant treatment. The closure of PDA on day 7 of life was in 19 of 20 infants of the ibuprofen group and 13 of 17 infants of the indomethacin group (P=0.159). Between the two groups, there were no significant differences with respect to clinical outcomes. CONCLUSION: Ibuprofen has similar effects to indomethacin in the rate of PDA closure. Our study demonstrates that prophylactic ibuprofen is relatively effective without significant differences with respect to clinical outcomes compared with indomethacin. Therefore, ibuprofen may be used as an alternative agent in the prophylaxis of PDA in preterm infants.
