各种不同的刺激作用于星型胶质细胞,可以导致胞浆内Ca2+浓度增加,进而释放更多谷氨酸作用于周边的神经元。大部分Ca2+来源于细胞内,小部分来源于细胞外。Ca2+内流是通过钙池操纵Ca2+通道(SOC)实现的。因此,作者观察在星型胶质细胞内Ca2+激活与谷氨酸释放过程中钙池操纵Ca2+通道(SOC)发挥了什么样的作用。已有研究显示星型胶质细胞所表达的TRPC通道(Ca2+通过瞬时受体电位通道相关蛋白)介导了钙池操纵Ca2+的内流。本文发现培养的星形胶质细胞以及从视皮质中新分离的星形胶质细胞表达TRPC1,TRPC4,和TRPC5。间接免疫组化显示这些蛋白存在于整个细胞中,然而机能检测TRPC1主要表达在质膜上。在新分离的星形胶质细胞中做标记,显示了在细胞发育过程中TRPC表达的改变。应用抗TRPC1的抗体,可以阻断TRPC1通道并且可以测定它们在培养的星形细胞的机械性和激动剂触发的钙离子内流过程中的作用。阻断TRPC1可以减少机械诱导的钙离子依赖性的谷氨酸盐的释放。这些实验数据表明,钙离子通过TRPC1通道的内流有助于钙离子在星形细胞中的信号传导以及由此引起的谷氨酸盐的释放。

利用基于能量改性水泥(EMC)工艺的低二氧化碳含量及低能耗的新技术,能够生产出一种高掺量火山灰混凝土(HVPC)。这种技术是通过将普硅水泥(PC)与火山灰(f.粉煤灰)的混合物投入到多组高强度研磨机中进行机械加工而实现的。这个工艺能够增加PC和火山灰颗粒的表面活性。粉煤灰可以与水泥一起处理,然后当作水泥使用。另外,粉煤灰可以与少量水泥(以重量计约5%)处理,然后被当作火山灰掺入混凝土中。后一种产品被称为CemPozz(机械加工火山灰),已由德克萨斯EMC产品有限公司于2004年在德克萨斯州杰威克的一家石灰石厂生产。CemPozz能够取代混凝土中高达60%的普硅水泥。根据ASTMC989有关《用于混凝土和砂浆的粒化高炉矿渣微粉标准规范》,CemPozz在混凝土中相当于100级高炉矿渣所起的作用。掺50%CemPozz的HVPC的强度与普通硅酸盐水泥混凝土的强度相当,凝结时间类似,但是能够减缓碱集料反应和干燥收缩。用CemPozz制成的混凝土具有较高的抗硫酸盐侵蚀、很低的Cl-离子渗透和显著减少开裂的特点。基于EMC水泥的高掺量火山灰混凝土具有三大环保优点:(1)活化粉煤灰,否则粉煤灰不能在混凝土中大量地替代普通水泥;(2)使用很少的水泥熟料作为混凝土胶凝材料,降低CO2排放;(3)降低与胶凝材料相关的能耗。通过计算结果可知,利用EMC技术,掺入水泥质量50%粉煤灰的混凝土可以减少45%的CO2排放量,从而降低45%的能耗。2004～2007年间,德克萨斯州利用CemPozz共生产150万立方米的高掺量火山灰混凝土(HVPC),并且有效地应用到各个方面(高速公路、住宅混凝土、喷射混凝土和混凝土砌块)。德克萨斯交通部(TX DOT)和宾州运输部(PENN DOT)已将CemPozz列入其施工规范,该规范允许这种材料在混凝土中替代50%(重量)的硅酸盐水泥。
