New data suggest 'jumping genes' play a significant role in gene regulatory networks

... to be transcribed and shares no sequence similarity with the genomes of invertebrates. "Our research suggests that many of these elements serve as distal enhancers for developmental genes," Haussler said. "A significant amount of the gene regulatory material appears to have indeed been put into place ...

New 'smart' materials for the brain

... membranes. Unlike the metal electrodes that are currently used in research and clinical applications, the nanotubes can create shortcuts between the distal and proximal compartments of the neuron, resulting in enhanced neuronal excitability. The study was conducted in the Laboratory of Neural ...

December 2008 Geology and GSA Today media highlights

... form, but Darwin's other question of why they are produced, and in such numbers, can only be answered by further work. Source of fluids forming distal Zn-Pb-Ag skarns: Evidence from laser ablation-inductively coupled plasma-mass spectrometry analysis of fluid inclusions from El Mochito, Honduras ...

Link possible between pet food contamination and baby formula contamination

... presented in the paper also shows that the melamine-cyanuric acid complex is soluble in acid, suggesting that acidification of the urine in the distal tubules of the kidney may be a reasonable treatment option. ...

Charcot-marie-tooth disease research funding

... system to investigate disease mutations in two small heat shock proteins, HSP27 and HSPB8, which can cause either CMT or the closely related disease distal Hereditary Motor Neuropathy (dHMN). The results of these studies will help to better understand the cell biological events leading to axon ...

Columbia study shows widely used artery clearing device does not help patients during heart attack

... patient outcomes. The procedure, called distal microcirculatory protection, is commonly and ... so much damage happens during a heart attack that distal protection is simply too little, too late," said ... were having heart attacks, half of whom received distal protection. During angioplasty procedures, ...

Clot-dissolving agent may be beneficial in treatment of severe frostbite

... within 24 hours of rewarming also appears to be necessary. Exclusion criteria would include superficial frostbite, involvement of the tips of the distal phalanges and contraindications to tPA, including concurrent trauma, neurological impairment or recent surgery or hemorrhage.” “Additional ...

Stomach receptor for H. pylori discovered

... in the stomach." These findings suggest that drugs that interfere with DAF binding could be used to prevent or treat peptic ulcer disease or distal gastric adenocarcinoma. These new drugs will be a welcome alternative to the current treatment for H. pylori infections which typically involves ...

Non-coding RNAs help silence the mammalian transcription

... the deletion involves the chromosome 15 that came from the mother, the child has Angelman syndrome. In the mouse, a cluster of nine genes on the distal end of the number 7 chromosome is imprinted. Dr. Tilghman and colleagues made a series of targeted alterations to ascertain which sequences are ...

How the octopus forms an elbow

... the arm segments according to where the object is grasped along the arm. The arm also forms a proximal joint near where the arm meets the body, and a distal joint near the suckers that have grasped the food. The medial joint typically exhibits the most movement during food retrieval. The authors also ...

Rice bioengineers pioneer techniques for knee repair

... In a third, and perhaps most impressive breakthrough, Athanasiou and Hu used the self-assembly approach to grow the entire articular surface of the distal femur. Each of these unbroken samples were tailored three-dimensionally to fit a specific rabbit femur. "If you told me 10 years ago that we would ...

Biotechnology's newest chemical tool

... pulls a tendon inside a synovial sheath, CYBERHAND's finger cables run through a Teflon sheath pulled by a DC motor. So the proximal, medial and distal phalanges, those bones between your finger knuckles, are all driven by the same tendon. This approach is called underactuation as there are more ...
