嘧啶二聚体 pyrimidine dimer,通常是指环丁烷型嘧啶二聚体。通过紫外线照射,DNA或RNA上相邻的嘧啶以共价键相互结合形成的结构,为紫外线的生物学作用为主要原因。通过光解酶的催化作用,吸收光后再恢复为单体。 News
Plasma d-dimer levels compared for each group, and in relation to (tumor size, stage, grade, lympho-vascular invasion, and lymph nodes involvement). Results D-dimer level was normal in group two (<0.25) mg/l and high in group one in other words, d-dimer level was increasing in ...

Notably, TaGT2L1D is able to interact with itself, which suggest a dimeriza- tion. It is likely that TaGT2L1D dimerization through the predicted nuclear localization signal in each monomer ensures the nuclear localization of the protein. Further analysis is needed to confirm the predicted ...

The dimer units are arranged in a nearly orthogonally tilted structure to form a zig-zag lattice. This structure is called a κ-type structure and various superconductors with relatively high Tc have this structure. Since one electron is removed from two BETS molecules, namely one dimer, to ...
This is about 3% shorter than the mean Li–O distances for the eight bonds that are not chelated at 1.976(10) Å. The structure of 3c (Figure 3c) has the most congested ligand 1c, with Dipp groups on nitrogen as well as the extra backbone methyl substituent. The same basic high-...
An alternative way to realize the high-TB compound is an introduction of a plural number of metal ions to increase the spin size S. Because it is usually difficult to align the metal ions in the ferromagnetic manner, sometimes, the ferrimagnetic interaction using different valencies such as ...
