Molecular Cloning of a Profilin cDNA from Bombyx mori
Wei, Yadong,Gui, Zhongzheng,Choi, Young Soo,Guo, Xijie,Zhang, Guozheng,Sohn, Hung Dae,Jin, Byung Rae Korean Society of Sericultural Science 2004 International Journal of Industrial Entomology Vol.9 No.1
The actin-binding protein profilin cDNA was firstly isolated from the lepidopteran insect, silkworm Bombyx mori. The B. mori profilin cDNA contains an open reading frame of 378 bp encoding 126 amino acid residues and possesses three cysteine residues. The deduced amino acid sequence of the B. mori profilin cDNA showed 80% identity to Apis mellifera profilin and 72% to Drosophila melanogaster profilin. Northern blot analysis showed that B. mori profilin is highly expressed in epidermis and less strongly in silk gland. In addition, Northern blot analysis revealed the presence of B. mori profilin transcripts in all tissues examined, suggesting that B. mori profilin gene is expressed in most, if not all, body tissues.

Dissolution Kinetics of Thiourea in Triglycol Solution
Li, Hua,Guo, Feng,Hu, Guoqin,Zhao, Lei,Zhang, Yadong Korean Chemical Society 2010 대한화학회지 Vol.54 No.1
이소프로필 멀케푸탄은 중요한 약품 중간체이며 싸이오우레아와 트리글리콜은 이소프로필 멀케푸탄을 합성을 하는데 중요한 화합물이다. 그러므로 트리글리콜 용액에서의 싸이오우레아의 용해는 이소프로필 멀케푸탄의 생산에 중요하다. 트리글리콜용액에서 싸이오우레아의 용해 반응속도론을 조사하고 이소프로필 멀케푸탄을 생산하는 대체 공정을 제시하는것이 본 연구의 목적이다. 트리글리콜용액에서 싸이오우레아의 용해 반응속도론을 조사하기 위하여 용액 농도와 반응 온도를 중점적으로 관찰하였다. 싸이오우레아의 용해속도는 용액농도와 온도가 증가할수록 증가하였다. Isopropyl mercaptan is an important pharmaceutical intermediate and chemical material. And thiourea and triglycol are the main materials for the synthesis of isopropyl mercaptan. Therefore the dissolution of thiourea in triglycol solution is very important for the production of isopropyl mercaptan. The aims of this study are to examine the dissolution kinetics of thiourea in triglycol solution, and to present an alternative process for producing isopropyl mercaptan. In order to investigate the dissolution kinetics of thiourea in triglycol solution, the concentrations of solution and reaction temperature were selected as experimental parameters. It was determined that the dissolution rate of thiourea increased with the increase in solution concentration and temperature. An empirical equation was used in fitting the data. Statistical analysis indicated small errors and the results should be reliable.

Molecular Cloning of a LIM Protein cDNA from the Mulberry Longicorn Beetle, Apriona germari
Gui, Zhongzheng,Wei, Yadong,Yoon, Hyung Joo,Kim, Iksoo,Guo, Xijie,Jin, Byung Rae,Sohn, Hung Dae Korean Society of Sericultural Science 2004 International Journal of Industrial Entomology Vol.9 No.1
Here we report the molecular cloning of a LIM protein cDNA of the CRP (cysteine-rich protein) family from the mulberry longicorn beetle, Apriona, geramri. The A. germari LIM protein cDNA contains an open reading frame of 276 bp encoding 92 amino acid residues with a calculated molecular weight of approximately 10 kDa. The A. germari LIM protein contains the cysteine-rich consensus sequence of LIM domain and the glycine-rich consensus sequence observed in cysteine-rich protein family 1 (CRP1). The potential nuclear targeting signal is retained. The deduced amino acid sequence of the A. germari LIM protein cDNA showed 81 % identity to both Bombyx mori muscle LIM protein (Mlp) and Drosophila melanogaster Mlp60A and 77% to Epiblema scudderiana Mlp. Northern blot analysis showed that A. germari LIM protein is highly expressed in epidermis and muscle, and less strongly in midgut, but not in the fat body.

Cloning and mRNA Expression of an Actin cDNA from the Mulberry Longicorn Beetle, Apriona germari
Gui, Zhongzheng,Lee, Kwang Sik,Wei, Yadong,Yoon, Hyung Joo,Kim, Iksoo,Guo, Xijie,Sohn, Hung Dae,Jin, Byung Rae Korean Society of Sericultural Science 2004 International Journal of Industrial Entomology Vol.9 No.2
Actin is a ubiquitous and highly conserved protein found in eukaryotic organisms. In this study, we describe the cDNA cloning and mRNA expression of an actin gene from the mulberry longicorn beetle, Apriona germari. The A. germari actin cDNA is 1524 bp containing a complete 1128 bp open reading frame that encodes a polypeptide of 376 amino acid residues with a predicted molecular weight of about 41.5 kDa. The deduced amino acid sequence of the A.germari actin cDNA showed 99% protein sequence identity to Homalodisca coagulata actin, differing at only two amino acid positions, and 92-98% protein sequence identity to known insect species actins. The predicted three-dimensional structure of A. germari actin revealed the four residue hydrophobic pulg loop characteristic of the actin family. Northern blot analysis showed that A. germari actin is highly expressed in epidermis and muscle, and less strongly in midgut, but not in the fat body of A. germari larva.

Purpose: Perioperative glucocorticoids have the potential to increase the risk of tumor metastasis. However, the relationship between perioperative glucocorticoids and oncologic outcomes remains controversial. The present study was undertaken to evaluate the association of perioperative glucocorticoids with clinicopathologic outcomes following radical cystectomy (RC). Materials and Methods: We screened and included 185 patients who underwent radical surgery for bladder cancer in our center between 2009 and 2018. The Kaplan–Meier method was applied, and a log-rank test was used to estimate differences in metastasis-free survival (MFS) and overall survival (OS) between the groups. Multivariate Cox proportional hazards regression models were used to analyze any association of glucocorticoids with clinical outcomes. Results: A total of 76 (41.1%) patients received perioperative glucocorticoids. Median postoperative follow-up was 2.0 years. Kaplan–Meier survival curve indicated that the glucocorticoids group was significantly associated with increased distant MFS (p=0.008) but not with OS. In the multivariate analysis, no significant differences were observed for MFS between the groups. Interestingly, when the variable of blood transfusion was excluded from the multivariate analysis model, we found that patients receiving glucocorticoids were independently associated with worse MFS (hazard ratio, 1.790; p=0.030). Furthermore, the partial correlation analysis showed a significant positive correlation between perioperative glucocorticoids and blood transfusion (r=0.604, p<0.001). In the nontransfusion subgroup, propensity score matching showed that patients receiving glucocorticoids had a higher risk of distant metastasis. Conclusions: Perioperative glucocorticoids were associated with a higher rate of distant metastasis in patients undergoing RC for bladder cancer.
