Agilent Technologies releases automated literature search tool for biology researchers

..."Agilent's Literature Search plug-in for Cytoscape makes automatic literature mining freely accessible to the public, with an algorithmic approach that is first-rate." "Agilent is committed to accelerating the productivity of biologists," said Jim Hollenhorst, director of the Molecular Technologies Labora...

Breakthrough method in nanoparticle synthesis paves the way for new pharmaceutical and biomedical applications

...ormally exist in a homogeneous liquid phase, which makes them difficult to be separated and reused. Prof. Ying’s group at IBN has developed novel approaches to immobilize these catalysts on nanoporous materials synthesized by its wet-chemical technique. This renders the catalysts in a solid form, enabling...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...d risk of stroke and heart attack, and the disease makes it difficult to control blood sugar levels in people with diabetes. If that’s not bad enough, pregnant women with periodontal disease are seven times more likely to deliver low-birth-weight, preterm babies. Proteins are important to study because the...

Affymetrix and Stratagene Announce Strategic Software Alliance

...our GeneChip platform and the ArrayAssist software makes the industry-leading methods for measuring gene expression on a genomic-scale available to an ever broadening community of life scientists." As part of the agreement, Stratagene has joined the community of Affymetrix partners developing methods for ...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...ering and Applied Sciences. " Another feature that makes emissive polymersomes so useful is that they self-assemble. Simply mixing together all component parts gives rise to these functional nanometer-sized, cell-like vesicles." In their study, the researchers demonstrate how they can use these emissive p...

Multiple Campylobacter Genomes Sequenced

...quences, scientists can learn much more about what makes a bacteria tick than they can learn from a single sequence. Derrick Fouts and his colleagues have taken this comparative approach with Campylobacter. Infection with a Campylobacter species is one of the most common causes of human bacterial gastroen...

Drug-resistant bacteria on poultry products differ by brand

...esence of this drug-resistant form of the bacteria makes the antibiotic less effective in human medicine. Especially vulnerable are the very young, the elderly and people whose immune systems are compromised. In 2000, the Food and Drug Administration proposed to withdraw approval of fluoroquinolone drugs ...

Hirsute Or Hairless? Two Proteins May Spell The Difference

...ntal biology. The dispensability of hair follicles makes them the perfect model system for studying this question—specifically, how structures and organs develop from buds. In a new study, Elaine Fuchs and colleagues use a three-pronged approach—involving gene expression analysis, transgenic mice, and cell...

Norovirus, AIDS vaccine and Hepatitis Virus

...) was made noninfectious by removing the gene that makes reverse transciptase (a protein the virus requires to replicate). Four macaques were injected with the noninfectious vaccine, while two control animals remained unvaccinated. Both groups were challenged with SHIV. All four of the immunized macaques b...

Probing the promise and perils of nanoparticles

...es engineering make them less harmful, but it also makes them better at what we want them to do. You don't lose anything; it's all a gain." More recently, Leroueil studied other types of charged nanoparticles called polycationic polymers---already being used to deliver drugs and genes---to see if they beh...

Chemists identify immune system mechanism for methamphetamine binges

...ystem to attack methamphetamine in such a way that makes users inclined to use more of the drug, the researchers say. Their study, which paints a clearer picture of the drug's effect on the immune system and its potential for abuse, was described today at the 229th national meeting of the American Chemical...

Great White shark evolution debate involves WSU Lake Campus geology professor

The research scientist makes imprints of the teeth, then digitizes the picture to establish grids of different combinations that are analyzed by a sophisticated computer program. He even uses an electron microscope to view different serration designs of shark teeth. "Our analys...

Moreover, the mechanism through which the organism becomes so pathogenic once the protective barrier of the skin is removed remains unclear. In their study appearing online on February 3 in advance of publication in the March 1 p...

Stem Cell Research Shows Potential for Replacing Tissue Damaged in Heart Attacks

Within the general population, several variations of the CYP1A1 gene exist, and the variants differ from one ...

Multi-purpose protein regulates new protein synthesis and immune cell development

Reservoirs may accelerate the spread of invasive aquatic species, researchers say

Just as disturbance makes a landscape susceptible to invasion by alien plant species, the construction of reservoirs around the globe could be contributing to the accelerating spread of exotic aquatic species, according to a Forum article in the June 2005 issue of BioScience....
