Duchenne/Becker muscular dystrophy are the major neuromuscular disorders with X-linked recessive inheritance. Preimplantation diagnosis of sex determination has been generally used to avoid male pregnancies with these diseases. However, in order to determine if the embryo is normal, carrier or affected regardless of the sex, there is a need for a combined analysis of specific exon on dystrophin gene as well as sex determination of embryo using the same biopsied blastomere. If the exon deletion is not determinable, further diagnosis of carrier or patient can be performed by haplotype analysis. In this study, we applied the primer extension preamplification (PEP) method, which amplifies the whole genome, in 40 cases of single amniocyte and 40 cases of chorionic villus cell. We analysed haplotypes using two (CA)n dinucleotide polymorphic markers located at the end of 5' and 3' region of the dystrophin gene. Exon 46 of dystrophin gene and DYZ3 on chromosome Y were chosen as a target sequence for coamplification PCR. Upon optimizing the conditions, the amplification rates were 91.25% (73/80) for haplotypes (92.5% in amniocyte, 90% in chorionic villus cell) and 88.75% (71/80) for coamplification (85% in amniocyte, 92.5% in chorionic villus cell). The result of the study indicates that haplotypes analysis and coamplification of dystrophin and Y-specific gene using PEP can be applied to prenatal and preimplantation diagnosis in Duchenne/Becker muscular dystrophy making it possible to determine if the fetus is a carrier or an affected one.

Purpose: This study aimed to identify factors affecting subjective cognitive decline (SCD) in men and women. Methods: This study was conducted based on data from the 2021 Korea Community Health Survey, and targeted a total of 80,026 men and 98,753 women aged 40 or older who responded to the SCD assessment. Multivariate logistic regression analysis using a complex sample was performed to identify factors influencing SCD. Results: Of the participants, 19,438 (22.7%) men and 30,826 (29.9%) women in the community reported SCD. Significant factors that influence SCD in both groups were age, education level, subjective health status, and depressive symptoms, and the strongest risk factor was depressive symptoms. Compared to women, men's monthly income, flexibility exercise, hypertension, and diabetes mellitus were found to be significant factors on SCD and Healthcare services affected SCD only in women. Medical services affected SCD only in women. Conclusions: When planning and providing intervention programs for cognitive function, it is necessary to reflect differences in factors associated with SCD according to sex.

Purpose : To identify factors related to the severity and frequency of hot flush of postmenopausal women who participated in a clinical trial. Methods : A cross-section study of 34 postmenopausal women between 40 and 60 years of age was done. VAS(visual analog scale) was used to evaluate the hot flush degree. Statistical analysis was performed with multiple linear regression analysis. Results : Hot flush VAS was proportional to the percent body fat with 1.467 regression coefficient (p-value= 0.010). It implies that the symptom of hot flush becomes worse as the percent body fat increases. Some hormones also have effects on hot flush. We found that LH might cause increment of hot flush VAS(i.e., the corresponding regression coefficient is 0.912). Sasang constitution was not relevant to the hot flush degree. Hot flush VAS seemed to increase as the vascular aging degree by SA-2000 getting worse, but it was not statistically significant (p-value= 0.594). Conclusion : This study is a part of a prospective clinical trial. For more accurate result, larger-scale cross-section study or clinical trial are necessary.

Trichomonas vaginalis is a flagellated protozoan parasite that causes vaginitis and cervicitis in women and asymptomatic urethritis and prostatitis in men. Mast cells have been reported to be predominant in vaginal smears and vaginal walls of patients infected with T. vaginalis. Mitogen-activated protein kinase (MAPK), activated by various stimuli, have been shown to regulate the transcriptional activity of various cytokine genes in mast cells. In this study, we investigated whether MAPK is involved in ROS generation and exocytotic degranulation in HMC-1 cells induced by T. vaginalis-derived secretory products (TvSP). We found that TvSP induces the activation of MAPK and NADPH oxidase in HMC-1 cells. Stimulation with TvSP induced phosphorylation of MAPK and $p47^{phox}$ in HMC-1 cells. Stimulation with TvSP also induced up-regulation of CD63, a marker for exocytosis, along the surfaces of human mast cells. Pretreatment with MAPK inhibitors strongly inhibited TvSP-induced ROS generation and exocytotic degranulation. Finally, our results suggest that TvSP induces intracellular ROS generation and exocytotic degranulation in HMC-1 via MAPK signaling.

Purpose: This study was to obtain a understanding of breast cancer women with high risk for hereditary cancer syndrome. Method: A micro-ethnography was used, including participation observation, open-ended in-depth interviews. Results: Two major arguments were derived. First, When Korean women at high risk to hereditary breast cancer make a decision about whether to take a genetic test, they are strongly motivated by a desire to preserve close kinship bonds and "family love" among their siblings, parents and children. Second, Even after genetic risk assessment and counseling services, Korean women at high-risk for developing a hereditary breast cancer who have been informed that they are mutation carriers, still hold onto previous beliefs about cancer causation. Their cancer prevention strategies are constructed according to their unchanged perceptions and beliefs about cancer causation. Conclusion: More sensitive genetic counseling program needs to be developed. Referral programs and clinical services must be attentive to cultural values and beliefs otherwise cultural attitudes and practices toward genetic counseling will not change.

Purpose: The purpose of this study was to develop an exercise program to prevent osteoporosis in working women and to examine its effects on bone mineral density (BMD). Method: The subjects of the study were 55 working women. The experimental group participated three times per week for twelve weeks in this exercise program. T-test and ANOVA, Pearson's correlation coefficients were used to analyze the data. Results: The BMD of the experimental group prior to participating in the exercise program was 0.9301 $(\pm08620)g/cm^2$. However, after the exercise program, the BMD increased to 0.9415 $(\pm1117)g/cm^2$ (t=-2.338, p=.026). Moreover, in relations to BMD and physiological variables, there were significant correlations between BMD and physical activity (r=.294, p=.030), as well as between BMI and physical activity (r=.267, p=.049). Conclusion: In this study, BMD in the experimental group had significantly increased after their participation, while the control group had decreased. Thus, this study showed that the exercise program developed for working women is effective in maintaining BMD and consequently preventing osteoporosis.

Cervical cancer is the third most common cancer in women worldwide and there is a significant association between human papillomavirus (HPV) infection and cervical cancer. Certain HPV groups, labeled high-risk (HR) HPV groups, are strongly associated with malignancies of the human cervix. HPV prevalence and genotype distribution were analyzed using the REBA $HPV-ID^{(R)}$ (YD Diagnostics, Yongin, Korea) assay based on the reverse blot hybridization assay (REBA) with a total of 324 liquid-based cytology samples from women in Western Shandong Province, East China and results were compared with cytological diagnosis. Most of the HPV genotypes that were detected in high-grade cervical lesions were HR-HPV genotypes such as HPV 16, 18, 33, 53, and 58. The prevalence of these HR-HPV genotypes increased in high-grade cervical lesions. However, from low- to high-grade cervical lesions, the ability to detect LR-HPV genotypes decreased. Additionally, in general, the single HPV genotype infection rate increases in proportion to the severity of the lesion. The study findings suggest that a currently available preventive vaccine against HPV 16 and 18 may have limited effectiveness for prevention of all HPV infection in this province. Finally, based on these findings, these data could guide national or regional vaccination programs in the Western Shandong Province of East China to substantially reduce the burden of cervical lesions.

Trichomoniasis is a sexually transmitted disease due to infection with Trichomonas vaginalis, and it can cause serious consequences for women's health. To study the virulence factors of this pathogen, T. vaginalis surface proteins were investigated using polyclonal antibodies specific to the membrane fractions of T. vaginalis. The T. vaginalis expression library was constructed by cloning the cDNA derived from mRNA of T. vaginalis into a phage ${\lambda}$ Uni-ZAP XR vector, and then used for immunoscreening with the anti-membrane proteins of T. vaginalis antibodies. The immunoreactive proteins identified included adhesion protein AP65-1, ${\alpha$-actinin, kinesin-associated protein, teneurin, and 2 independent hypothetical proteins. Immunofluorescence assays showed that AP65-1, one of the identified immunogenic clones, is prevalent in the whole body of T. vaginalis. This study led us to identify T. vaginalis proteins which may stimulate immune responses by human cells.
