64位时代大功率电源选购通

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”。[编者按]     

温谈CPU真假辨别

如果购买了不合格的CPU就会给电脑装上一颗脆弱的“芯”，后果很可能烧坏其他配件，给我们带来麻烦。认清假冒伪劣产品的真实面目。法和如何辨别做一翻介绍，让大家认清假冒伪劣产品的真实面目。[编者按]     

GDDR4小宇宙爆发显存换代进行时

芯片厂商不断提升运行频率,促使显存频率保持高增长以符合硬件的发展。随着2006年首片采用GDDR4显存的显卡Radeon X1950XTX上市以来,GDDR4显存正式与消费者见面。和GDDR3的普及一样,目前GDDR4逐渐步入成熟阶段,因此我们可以看到不少采用GDDR4显存的显卡出现在市场上,尤其是HD3870诞生后,更是将GDDR4全面推向舞台,加上目前显存频率已经发展到超越2000MHz的局面,可以预见2008年GDDR4显存将会完全爆发,最终成为显卡主流配置。     

家用经济型打印机选购指南

伴随着生活水平的日益提高，人们对家用小型打印机的需求主要表现在文字、多媒体以及图像的打印输出等方面，这就要求打印机拥有较好的色彩表现能力、快速打印能力和很好的稳定性。从目前的打印机市场来看，价格偏高的激光打印机普通家庭用户接受起来有一些困难，老式的针式打印机已经无法满足用户对一些打印效果的要求，所以只有打印成本适中且打印效果出色的彩色喷墨打印机才能满足大家的要求。但是，喷墨打印机产品种类繁多，对于普通家庭用户而言，想要在市场上挑选到一款称心如意的产品确实是一个棘手的问题。[编者按]     

廉价独立声卡导购

随着人们对音质的要求越来越高，声卡得到了长足的发展。虽然很长一段时间，主板上的集成声卡满足了部分朋友对声音播放的要求，但是想要获得更好的音质，还是需要靠独立声卡。而且，随着近段时间越来越多的朋友喜欢用电脑录制自己的卡拉OK，音质表现优异的独立声卡就成了不少朋友的首选。所以，这里就向大家介绍一些价廉物美的独立声卡。[编者按]     

Clearance of FGF‐23 during continuous renal replacement therapy

FGF‐23 is a 32 kDa protein that is a key regulator of phosphorus and vitamin D metabolism. Emerging evidence also demonstrates that FGF‐23 increases within 24 hours of acute kidney injury (AKI) and may be associated with adverse clinical outcomes. We conducted this study to evaluate FGF23 clearance during continuous veno‐venous hemofiltration (CVVH) in critically ill patients with AKI. We demonstrate that plasma clearance of FGF‐23 during CVVH is ～11 mL/min and the mean sieving coefficient is 0.27 ± 0.1. Future studies will need to clarify FGF‐23's role in adverse outcomes among AKI patients, and whether therapies aimed at reducing FGF‐23 levels may be beneficial.     

液晶屏需要保暖防寒

前不久．笔者陪朋友去电脑城选购了一款宏基的Aspire 3609NWXMi笔记本。可是买完后不到一周，朋友却告知笔记本电脑出问题了。     

轻松掌控LGA775风扇技术

买CPU散热风扇都想买一款能调速的CPU风扇。这样在CPU发热量小的时候可以将风扇转速调低以减少噪音。当CPU全速工作发热量大的时候又能将风扇转速调高，更好地散发热量。其实，如果你用的是LGA775接口的Intel CPU，那智能风扇就能立马实现。[编者按]     

Common FABP4 Genetic Variants and Plasma Levels of Fatty Acid Binding Protein 4 in Older Adults

We examined common variants in the fatty acid binding protein 4 gene (FABP4) and plasma levels of FABP4 in adults aged 65 and older from the Cardiovascular Health Study. We genotyped rs16909187, rs1054135, rs16909192, rs10808846, rs7018409, rs2290201, and rs6992708 and measured circulating FABP4 levels among 3190 European Americans and 660 African Americans. Among European Americans, the minor alleles of six single nucleotide polymorphisms (SNP) were associated with lower FABP4 levels (all p ≤ 0.01). Among African Americans, the SNP with the lowest minor allele frequency was associated with lower FABP4 levels (p = 0.015). The C-A haplotype of rs16909192 and rs2290201 was associated with lower FABP4 levels in both European Americans (frequency = 16 %; p = 0.001) and African Americans (frequency = 8 %; p = 0.04). The haplotype combined a SNP in the first intron with one in the 3′untranslated region. However, the alleles associated with lower FABP4 levels were associated with higher fasting glucose in meta-analyses from the MAGIC consortium. These results demonstrate associations of common SNP and haplotypes in the FABP4 gene with lower plasma FABP4 but higher fasting glucose levels.
