Bioptical microcycles of laminated speleothems from China and their chronological significance

Interfaces of microlayers, in most stalagmites from China, consist of opaque and organic materials. Observed with microscope, the interfaces seem dark under transmitted light and luminiferous under reflected f...

Neurotoxicity induces cleavage of p35 to p25 by calpain

Cyclin-dependent kinase 5 (cdk5) and its neuron-specific activator p35 are required for neurite outgrowth and cortical lamination^1,2,3. Proteolytic cleavage of p35 produces p25, which accumulates in the brains of...

Photoactivated γ-secretase inhibitors directed to the active site covalently label presenilin 1

Cleavage of amyloid precursor protein (APP) by the β- and γ-secretases generates the amino and carboxy termini, respectively, of the Aβ amyloidogenic peptides Aβ40 and Aβ42—the major constituents of the amyloi...

The combined genotypes effect of ESR and FSHβ genes on litter size traits in five different pig breeds

Estrogen receptor (ESR) and Follicular-stimulating hormone beta subunit (FSHβ) genes were chosen as candidates to determine whether they control litter size and some other reproductive traits in swine. 269 sow...

Depositional architecture and develo** settings of large-scale incised valley and submarine gravity flow systems in the Yinggehai and Qiongdongnan basins, South China Sea

In the Ying-Qiong basins in the South China Sea developed a set of giant inner shelf slope and submarine gravity flow deposits in the Ying-Huang formations since the Late Miocene. These deposits can be classif...

Adaptation in the chemotactic guidance of nerve growth cones

Pathfinding by growing axons in the develo** nervous system may be guided by gradients of extracellular guidance factors. Analogous to the process of chemotaxis in microorganisms, we found that axonal growth...

Cloning and identification of measles virus receptor gene from marmoset cells

The measles virus (MV) strains with mutated hemagglutinin gene (ha) lost the capacity to infect its sensitive host cells (Vero cells), but it may infect the marmoset B-lymphoblastoid cell line B95a. From above, w...

Paleotemperature changes over the past 3000 years in eastern Bei**g, China: A reconstraction based on Mg/Sr records in a stalagmite

The Mg/Sr ratio in a stalagmite, which is directly proportional toD _Mg/ca, the solid-liquid distribution coefficient of Mg, is proposed as a geochemical thermometer to estimate paleotemperature ch...
