Aspirin targets key protein in neurodegenerative diseases
Aspirin protein neurodegenerative diseases
2015/12/7
A new study finds that a component of aspirin binds to an enzyme called GAPDH, which is believed to play a major role in neurodegenerative diseases, including Alzheimer’s, Parkinson’s and Huntington’s...
Discovery could open door to frozen preservation of tissues, whole organs
frozen preservation tissues organs

Researchers in the College of Engineering at Oregon State University have discovered a new approach to “vitrification,” or ice-free cryopreservation, that could ultimately allow a much wider use of ex...
Nearly 37 million people worldwide are living with HIV. When the virus destroys so many immune cells that the body can’t fight off infection, AIDS will develop. The disease took the lives of more than...
Blood test results vary from drop to drop in fingerprick tests

When it comes to needles and drawing blood, most patients agree that bigger is not better. But in the first study of its kind, Rice University bioengineers have found results from a single drop of blo...
光学扫描仪或可直接筛查乳腺癌
光学扫描仪 筛查乳腺癌
2015/10/26
美国研究人员在2015年10月23日出版的国际期刊《生物医学物理与工程快报》上发表研究论文称，他们开发出一种手持光学扫描仪器，有潜力实现乳腺肿瘤实时成像。这个最初由佛罗里达国际大学开发研制的仪器，使用了一种近红外激光二级光源来生成乳腺组织图像。其先进之处在于能够更好地贴合乳房的形状，而且能够为传统技术很难成像的胸腔壁区域成像。
Both cardiac cells in the heart and neurons in the brain communicate by electrical signals, and these messages of communication travel fast from cell to cell as 'excitation waves'. Interestingly, such...
If you need a working miniature brain — say for drug testing, to test neural tissue transplants, or to experiment with how stem cells work — a new paper describes how to build one with what the Brown ...
New Tech Automatically ‘Tunes’ Powered Prosthetics While Walking
Tunes Powered Prosthetics Walking

科学家首次培育出人类精子（图）
科学家 培育 人类精子
2015/9/24
科学家真的能够在培养皿中培育出精子吗？2015年年初，法国科学家称他们可以做到这一点。近日，这些科学家正打算对他们的技术申请专利保护，尽管他们的详细研究方法和研究结果仍在接受同行评议。法国里昂Kallistem生物技术公司的Philippe Durand 和Marie-Hélène Perrard表示，他们的研究方法可以把取自人类、大鼠和猴子的细精管（即在实验过程中生成精子的组织）诱导为成熟的精子...
一种细胞外基质蛋白能刺激心肌细胞再生（图）
细胞外基质蛋白 心肌细胞再生
2015/9/17
美国科学家在小鼠和猪身上进行的生物学研究显示，一种名为卵泡抑素样蛋白1（Fstl1）的蛋白，能够在成年哺乳动物心脏病发作后诱导心脏肌肉细胞再生。该结果意味着，修复心外膜中Fstl1的表达可能正是刺激心脏“重生”的有效办法，以此可开辟出全新的治疗手段。

A protein domain once considered of little importance may be key to helping patients who are fighting acute myeloid leukemia (AML) avoid a relapse.Researchers at Rice University, working wit...
Mathematical ‘Gingko trees’ reveal mutations in single cells that characterize diseases（图）
Mathematical Gingko trees single cells characterize diseases
2015/9/18
Seemingly similar cells often have significantly different genomes. This is often true of cancer cells, for example, which may differ one from another even within a small tumor sample, as genetic muta...
In two recent papers in Analytical Chemistry (here & here), a group from the UC Davis Department of Electrical and Computer Engineering demonstrated that they could detec...
