Rat cumulus - enclosed oocyte ( ceo ) and denuded oocyte ( do ) both spontaneously resume meiotic maturation in vitro, when cultured for 2h, the germinal vesical breakdown percentage of do reaches up to 88 %, and ceos get 53 %. oocytes begin to extrude first polar body 1 ( fb1 ) when cultured for 8h. mouse oocyte spontaneous maturation in vitro can be inhibited by 4mm hypoxanthine ( hx ) or 25um 3 - isobutyl - methylxanthine ( ibmx ). while, 4mm hx can not inhibit the spontaneous maturation of rat oocyte, and the lowest effective concentration of ibmx to inhibit rat oocyle spontaneous maturation in vitro is 50um. treated with the same concentration of ibmx, gvbd percentage of rat ceo is lower than that of do, the results indicat that cumulus cells delay rat oocyte spontaneous maturation and potentate the inhibition effect of ibmx, but it ' s not the case on mouse

Ceo和do培養8h時都開始排出pb1 ；在卵母細胞成熟抑制模型中， 4mm次黃嘌呤（ hx ）和25 m的異丁基甲基黃嘌呤（ ibmx ）是小鼠卵母細胞成熟的有效抑制劑，但4mm的hx抑制大鼠卵母細胞成熟效果不理想，用hx - m199和hx - mem培養24h ， gvbd率分別為61 ， 81 ，而ibmx有效抑制大鼠卵母細胞自發成熟的最小濃度為50 m ， ibmx可以降低大鼠ceo和do的gvbd率，但ceo中的卵母細胞gvbd率要顯著低於do的gvbd率， 100 m的jbmx處理24h后，大鼠ceo和do的gvbd率分別為24 ， 84 ，提示卵丘細胞的存在可以延遲大鼠卵母細胞的自發成熟，有助於抑制卵母細胞成熟，但在小鼠上ceo和do的自發成熟差異不明顯。

High - mg volcanic rocks approach the primitive mantle compositions, and their magmatic source is close to the composition of bse, derives from the lower mantle and formed by this type - mantle rocks " fractional melting highly ( > 25 % ). high - mg volcanic magma, formed in the axis of the emei mantle plume, underwent the crystallization differentiation of olivines and some pyroxenes ; some olivines reflect fair cumulus crystallization

This simple two - step chemical enucleation procedure yields fully enucleated mouse oocytes in 85. 6 % of cumulus - oocytes complexes and 56 % of natural oocytes, significantly different ( p < 0. 05 ). since the enucleation rate of cumulus - oodles complexes is equivalent to that by micromanipulation, induced enucleation will greatly improve the whole efficiency in mouse somatic nulear transfer

該方法完全丟棄了傳統核移植的顯微操作及其繁瑣程序，是純粹的手工克隆（ hmc ） ，它的成功將會大大簡化核移植程序，提高核移植效率，加快其產業化的步伐。

When snow crystals strike supercooled droplets, the droplets will immediately freeze onto them. this process, called riming, forms soft particles known as snow pellets or grains. in temperate zones, the melting of snow pellets provides much of the rainfall from cumulus clouds

每當雪晶碰到過冷的水點時，它們會立刻凝固在一起，形成的軟粒子便是雪小球，而整個過程被稱為"蒙霜" ;在溫和的區域里
