Controlled Construction of Cu(I) Sites within Confined Spaces via Host-Guest Redox: Highly Efficient Adsorbents for Selective CO Adsorption.

Here, we designed a double-solvent/host-guest redox combined strategy to construct Cu sites in metal-organic frameworks (MOFs) for the first time. As a proof of concept, a representative MOF MIL-100(Fe) with tunable valence states of cations was employed as the host. The combined strategy realizes selective introduction of Cu precursors to the interior pores of MIL-100(Fe), remarkably minimizing the aggregation of Cu and subsequently formed Cu species.

Unusual ceria dispersion formed in confined space: a stable and reusable adsorbent for aromatic sulfur capture.

An unusual ceria dispersion was achieved by using the confined space between template and silica walls in as-prepared mesoporous silica, for the first time. The new adsorbents exhibit high adsorptive desulfurization activity and, more importantly, excellent stability and reusability, which is impossible to realize with conventional adsorbents.

[Effects of simvastatin on DNA synthesis in rat cardiac fibroblasts].

Objective: To investigate the effects of simvastatin (Sim) and the interference by mevalonate (MVA) against its effect on DNA synthesis in rat cardiac fibroblasts (CFs).

Methods: CFs were isolated from neonatal SD rats by trypsin digestion and growth-arrested CFs were stimulated with Sim and/or MVA at varied concentrations for different time lengths, and the DNA synthesis in the cells was measured by (3)H-thymidine ((3)H-TdR) incorporation assay.

Results: Sim decreased (3)H-TdR incorporation in the CFs in a concentration-dependent manner, and (3)H-TdR incorporation was significantly lower in cells treated with 1 x 10(-6) and 1 x 10(-5) mol/L Sim (1,175+/-202.

[Relation of the ST-segment elevation pattern in acute phase of anterior wall acute myocardial infarction to short-term prognosis].

Objective: To observe the relation of ST-segment elevation pattern of electrocardiogram (ECG) recorded in acute phase of anterior wall acute myocardial infarction (AMI) to short-term prognosis.

Methods: Sixty-two patients with first anterior wall AMI were divided into 3 groups according to ST-segment elevation pattern in lead V3 of a 12-lead ECG at admission. Patients in group A (n=18) were characterized by concave type of ST-segment elevation, group B (n=27) by straight type and group C (n=17) by convex type.
