过去因为机箱通常自带电源。所以我们很少主动去挑选，以为整合的东西很好，至少省事。但后来电脑硬件百花齐放般地发展，使得大家开始注意它。而且随着电脑进入64位跗代，单独选购一款大功率电源也非常有必要，但自选也带来不少问题，面对众多品牌我们该如何下手，更有奸商提供的产品比整合的电源还便宜，伴随着种种疑问，希望笔者提供的分析能帮大家早日找到自己的“心中所属”。

Cyclin-dependent kinase inhibitors(CKIs) are negative regulators of the cell cycle. They can bind to cyclin-dependent kinase(CDK)-cyclin complexes and inhibit CDK activities. We identified a single homologous gene of the CDK interacting protein/kinase inhibitory protein(Cip/Kip) family, BmCKI, in the silkworm, Bombyx mori. The gene transcribes two splice variants: a 654-bp-long BmCKI-L(the longer splice variant) encoding a protein with 217 amino acids and a 579-bp-long BmCKI-S(the shorter splice variant) encoding a protein with 192 amino acids. BmCKI-L and BmCKI-S contain the Cip/Kip family conserved cyclin-binding domain and the CDK-binding domain. They are localized in the nucleus and have an unconventional bipartite nuclear localization signal at amino acid residues 181-210. Overexpression of BmCKI-L or BmCKI-S affected cell cycle progression;the cell cycle was arrested in the first gap phase of cell cycle(G1). RNA interference of BmCKI-L or BmCKI-S led to cells accumulating in the second gap phase and the mitotic phase of cell cycle(G2/M). Both BmCKI-L and BmCKI-S are involved in cell cycle regulation and probably have similar effects. The transgenic silkworm with BmCKI-L overexpression(BmCKI-L-OE), exhibited embryonic lethal, larva developmental retardation and lethal phenotypes. These results suggest that BmCKI-L might regulate the growth and development of silkworm. These findings clarify the function of CKIs and increase our understanding of cell cycle regulation in the silkworm.

It is estimated that 30 million men in the United States suffer from some degree of erectile dysfunction (ED) and the incidence is aug mented with aging. Most studies have been focused on nitric oxide(NO) , a potent vasodilator releasted from non-adrenergic/non-cho linergic nerves or from endothelial cells. Although NO is thought to be the principal vasodilator, endothelial-derived hyperphlarization factors(EDHF) have been demostrated to play a crucial role in regulation of the tone of some vascular beds. Epoxyeicosatrienoic acids (EETs) , arachidonic acid metabolites of cytochrome P450(CYP) epoxygenases, have been proposed to function as EDHF. We hypoth
