| Of all human conditions, aging and death are perhaps the most universal. Unfortunately death among elderly populations is often a drawn out and painful affair, as advanced age is accompanied by marked rises in morbidity and mortality due to infectious diseases. Precisely why this is the case has been subject to a great deal of speculation, but one commonly held explanation is referred to as imm... more |

| Labeoninae is a subfamily in the family Cyprinidae of order Cypriniformes and inhabit fast flowing freshwater. This species is characterized with their highly modified and variable lips. Labeoninae fish is high in biodiversity and the largest species richness is in the karst region around southern China. In China, there are 26 genera, of which 12 are endemic. Therefore, Labeoninae has become a ... more |

Pore-forming toxins, such as aerolysin, are a largest group of bacterial virulent factors in pathogenic infections, which could oligomerize and form pores to the host-cell membranes, and therefore cause cellular lesions. Although it has been known that aerolysin-like proteins are also widely distribute in vertebrates, their biological functions are poorly known.
Most recently, Prof. ZHANG Y... more |

Polyploidization is an important mechanism that has caused many rapid speciation events and it increases genetic diversity of both plants and animals. Polyploidization occurs rarely in animals, especially in vertebrates. So far, little is known about the extent of multiple autopolyploid origins in vertebrates.
Using both mitochondrial (mtDNA) and nuclear DNA sequences from up to 1202 indivi... more |

Ants play critical roles in plant protection in ecosystem by acting as predators and taking herbivores, such as parasites, as their prey items. In this predator-herbivore-plant scenario, the density or behavior of herbivore is disturbed by the predator, and thereafter, the biomass of plant is indirectly increased. This cascade is called “trophic cascade”.
Through a three-month survey (fro... more |
