In the search for new and improved anticancer therapies, researchers have identified several potentially useful compounds. One of these agents is 2-methoxyestradiol-bis-sulphamate (2ME-BM), a sulphamoylated derivative of 2-methoxyestradiol....
Variable number tandem repeats in the promoter region of prostacyclin synthase gene in choline deficient rats [0.03%]

The leaf structure and micromorphology characterize plant species and reflex its interactions with the environment. Leaf epidermis sculptures aid high transpiration plants on light reflection. The form and distribution of epicuticular wax c...
Cobalt chloride stimulates phosphoinositide 3-kinase/Akt signaling through the epidermal growth factor receptor in oral squamous cell carcinoma [0.03%]
氯化钴通过表皮生长因子受体刺激磷脂酰肌醇3-激酶/蛋白激酶B信号在口腔鳞状细胞癌中的作用

Mi Heon Ryu et al.
Tumor cells are often found under hypoxic conditions due to the rapid outgrowth of their vascular supply, and, in order to survive hypoxia, these cells induce numerous signaling factors. Akt is an important kinase in cell survival, and its ...
Effect of morphological heterogeneity of somatic embryos of Melia azedarach on conversion into plants [0.03%]
蓝果树胚体形态异质性及其转化率的关系研究
