The human ELAV(embryonic lethal abnormal vision)-like protein HuR stabilizes a certain group of cellul ar mHNAs that contain AU- rich elements in their 3’ - untranslated region , To test the significance of HuR in carcinogenesis of head and neck squamous cell carcinomas(HNSCCs), we have investigated HuH expression from 32 benign epithelial lesions , 14 prema lignant epitheli al lesions and 80 HNSCCs, There were two different staining patterns of HuR in HNSCCs : nuclear expression was seen in 78 7% (63 of 80) 01' cases; and an additional cyto plasmic expression was seen in 28, 7%(23 of 80) 01 cases, Nuclear expression of HuR was s ignificantly increased in premalignant lesions and HNSCCs, whereas increased cytoplasπli c expression of HuR was only observed in HNSCCs Cytoplasmic HuR expression was significantly increased in pa tients of HNSCC younger than 60 yea rs , Al though there was no significant correlation between a natomic s ites of HNSCCs and HuR express ion , cyto plasmic HuR expression was highly increased in HNSCCs of larynx, There was no significant co rrela tion between HuR expression and other clinicopathological parameters such as histological type‘ tumor s ize‘ 0 1' n odal s tatus , ln conclusion, this study s uggests that overexpression of HuR in HNSCCs may be part of a regula tory pathway tha t co ntro ls the mHNA stability 0 1' several important targets in carcinogenesis of HNSCCs

Bacillus aryabhattai GW320 (= KACC 22234) was isolated from the rhizosphere of Cucumis sativus L. in Gunwi-gun, Republic of Korea, and its whole-genome sequence was analyzed in this study. Its whole genome consists of circular chromosomes and plasmids, with genome sizes of 6,036,752 bp and 152,341 bp, respectively. The G + C content of its chromosome is 61.5%. The chromosome and plasmid contain 5,599 proteincoding genes. Besides, genes related to auxin biosynthesis, urea degradation, and nitrogen assimilation were identified in the chromosome. Thus, Bacillus aryabhattai GW320 has the potential to be an agriculturally useful strain.

This study examines the present uses of smart devices among preschoolers and their relations to immersion tendency, self-control, and prosocial behaviors. The teachers and parents of 159 preschoolers aged 4-6 years attending kindergartens and childcare centers in Busan and South Gyeongsang Provinces participated in the survey. The findings were as follows: First, a majority of the preschoolers had the experience of using smart devices; Second, their smart-device immersion tendency was not severe; Third, the smart-device immersion tendency was negatively correlated to their self-control abilities and prosocial behaviors. It can be concluded that the age of experiencing smart devices is decreasing and their effects have substantial consequences in young children’s socio-cognitive development.
