Mammalian ubiquitous promoter isolated from proximal regulatory region of bovine MSTN gene.

Gene therapy is a promising method for treating inherited diseases by directly delivering the correct genetic material into patient cells. However, the limited packaging capacity of vectors poses a challenge. Minimizing promoter size is a viable strategy among various approaches to address this issue.

[The mucosal changes and influencing factors in upper gastrointestinal anisakiasis: analysis of 141 cases].

Background/aims: Anisakiasis is a well known parasitosis resulted from eating raw seafoods and there were many reports of cases. However, its endoscopic and clinical characteristics have not been reviewed well. The aim of this study was to clarify the gastric mucosal changes and influencing factors of upper gastrointestinal (UGI) anisakiasis.

Preparation of highly monodispersed hybrid silica spheres using a one-step sol-gel reaction in aqueous solution.

The successful one-step preparation method of monodisperse hybrid silica particles was studied using organosilane chemicals in aqueous solution. In general, almost all of the hybrid silica materials were made by a complex method where organic materials were coated on the surface of silica substrate via chemical reaction. However, our novel method can be applied to prepare colloidal hybrid particles without using substrate material.

Effect of soil acidification on the growth of Korean pine (Pinus koraiensis) seedlings in a granite-derived forest soil.

The growth of pine trees has diminished in recent years in industrial areas of Korea. Soil acidification is believed to be responsible. To study its effects, we grew seedlings of three-year-old Korean pine in brown forest soil derived from granite, which had been treated with an acid solution, for 182 days.

Distribution of macropores in silica particles prepared by using multiple emulsions.

The distribution of macropores in silica particles prepared by the hydrolysis and condensation of TEOS in a hexane/water/decyl alcohol (O(1)/W/O(2)) multiple emulsion was investigated. To stabilize the emulsion structure, hydroxypropyl cellulose (HPC) was added into the O(2) phase and polyethylene glycol (PEG) was added into the water phase. Without HPC, the particles have an irregular shape and hardly have particulate forms.
