Cryptosporidium parvum is known as one of the most highly resistant parasites to gamma irradiation. To morphologically have an insight on the radioresistance of this parasite, ultrastructural changes in C. parvum sporozoites were observed after gamma irradiation using various doses (1, 5, 10, and 25 kGy) following a range of post-irradiation incubation times (10 kGy for 6, 12, 24, 48, 72, and 96 hr). The ultrastructures of C. parvum oocysts changed remarkably after a 10-kGy irradiation. Nuclear membrane changes and degranulation of dense granules were observed with high doses over 10 kGy, and morphological changes in micronemes and rhoptries were observed with very high doses over 25 kGy. Oocyst walls were not affected by irradiation, whereas the internal structures of sporozoites degenerated completely 96 hr post-irradiation using a dose of 10 kGy. From this study, morphological evidence of radioresistance of C. parvum has been supplemented.

PURPOSE: The purpose of this study was to explore decision making experiences of Korean women with breast cancer who underwent breast reconstruction with/after a mastectomy. METHODS: Data were collected during 2015-2016 through individual in-depth interviews with 10 women who had both mastectomy and breast reconstruction, and analyzed using phenomenological method to identify essential themes on experiences of making a decision to have breast reconstruction. RESULTS: Five theme clusters emerged. First, “expected loss of sexuality and discovery of autonomy” illustrates various aims of breast reconstruction. Second, “holding tight to the reputation of doctors amid uncertainty” specifies the importance of a trust relationship with their physician despite a lack of information. Third, “family members to step back in position” describes support or opposition from family members in the decision making process. Fourth, “bewilderment due to the paradox of appearance-oriented views” illustrates paradoxical environment, resulting in confusion and anger. Lastly, “decision to be made quickly with limited time to oneself” describes the crazy whirling process of decision making. CONCLUSION: Findings highlight aims, worries, barriers, and facilitators that women with breast cancer experience when making a decision about breast reconstruction. Deciding on breast reconstruction was not only a burden for women in a state of shock with a diagnosis of breast cancer, but also an opportunity to decide to integrate their body, femininity, and self which might be wounded from a mastectomy. These findings will help oncology professionals provide effective educational counselling before the operation to promote higher satisfaction after the operation.

OBJECTIVE: To investigate the effects of combination functional electrical stimulation (FES) and standing frame training on standing balance in stroke patients. METHODS: Patients who had hemiparesis and postural instability after stroke were randomly assigned to one of the two groups; study group underwent FES on the quadriceps and tibialis anterior muscle simultaneously with standing balance training. The control group received standing frame training and FES separately. Both the groups received their respective therapies for 3 weeks. Stability index in Biodex Balance master system, Berg Balance Scale (BBS), manual muscle test, the Korean version of Modified Barthel Index, and Korean version of Mini-Mental State Examination were used to evaluate the effects of the treatment. RESULTS: In total, 30 patients were recruited to the study group and 30 to the control group. Three weeks after treatment, both the groups showed improvement in postural stability scores and physical and cognitive functions. When changes in postural stability were compared between the groups, the study group showed more significant improvement than the control group with regards to the scores of BBS and the stability indices. CONCLUSION: In this study, we found the therapeutic effectiveness of combined therapy of FES and standing frame in subacute stroke patients. The presented protocol is proposed as time-saving and can be applied easily in the clinical setting. Thus, the proposed combined therapy could be a useful method for improving standing balance in subacute stroke patients.

Heterotopic pregnancy occurs when there are coexisiting intrauterine and ectopic pregnances. It occure, more often, due to assisted reproductive technology such as IVF-ET, GIFT and increased pelvic inflammatory diseases. We present a case of heterotopic pregnancy confirmed by surgical removal of ruptured left ovarian pregnancy and sonographic finding of the intrauterine pregnancy following natural conception.

Obesity is a leading risk factor for insulin resistance, hypertension, hyperlipidemia, and cardiovascular complications, collectively referred to as metabolic diseases. Given the prevalence of obesity and its associated medical problems, new strategies are required to prevent or treat obesity and obesity-related metabolic effects. Here we summarize contributors of obesity, and molecular mechanisms controlling adipogenesis from studies in mammalian systems. We also discuss the possibilities of using Drosophila as a genetic model system to advance our understanding of players in fat biology.

Esophageal perforation continues to be associated with high mortality - 20% to 30% - despite advances in surgical techniques. Traditional surgery has been the mainstay of treatment for perforation, but recent advances in endoscopic closure devices has increased therapeutic options for selected patients. Our patient had a fishbone-induced esophageal perforation. He was treated successfully with endoscopic clipping, antibiotics and parenteral nutrition. We report this case and provide a review of the relevant literature.

PURPOSE: Because NELL2 expression is strictly restricted only in neurons in developing and post- differentiated neural tissues, it is thought to be involved in the neuronal differentiation during development and in the maintenance of neuronal physiology in the post-differentiated neurons. In this study, we examined whether NELL2 is involved in the regulation of cell cycle and apoptosis in the hippocampal neuroprogenitor HiB5 cells. METHODS: Effects of NELL2 on the cultured HiB5 cell numbers, DNA fragmentation, and proteins involved in the regulation of the cell cycle were measured. RESULTS: NELL2 induced a decrease in cell numbers and an increase in G1 phase arrest. Moreover, transfection of NELL2 resulted in an increase of DNA fragmentation that shows an evidence of apoptosis. Contents of proteins involved in the regulation of cell cycle were also changed by transfection of NELL2 expression vectors. CONCLUSION: This study suggests that NELL2 plays an important role in the regulation of cell cycle and apoptosis of neurons.

Teacher's satisfaction with school lunch programs run by foodservice(FS) management types were surveyed with questionnaire at 5 middle and 4 elementary schools. The 88 middle and 104 elementary school teachers who participated and schools' FS management were of 5 types : self/conventional, contracted/conventional, contracted/commissary and contracted/dosirak delivery. Most teachers knew correctly their schools' present FS management types and thoroughly understood the main reasons for needing school lunch program with proper nutrition, better taste and balanced diets in addition to the first reason its less work than preparing homelunches. Teacher's satisfactions with their present school FS were high in self/conventional and contracted/conventional and was very low in contracted/commissary and contracted/ dosirak Taste, hygiene, nutrition and dining facilities in turn were pointed out to be improved : firstly hygiene in the self and firstly taste in the contracted. Particularly dining-rooms were found to have narrow space, uncomfortable chairs and tables, unclean, and having unpleasant smells. Teachers observed that the overall students' food habits such as eating more various foods and better table manners through that school lunch programs, particularly the self-managed types were improved. Conclusively most teachers emphasized school lunch programs to be continued and preferred self-managed types and contracted/conventional types as the second best in having less work to manage, better, taste, nutrition and hygiene, less cost and better nutrition education in turn. And they thought school founders should handle the finances needed to newly establish or repair the school FD facilities, otherwise provided with the partial aid of student's parents.
