The Future of the FDA: Operating in an Electronic World

Oct 12

Acording to an Axendia reseach study, the FDA is currently shifting its organizational and technology infrastructures to facilitate electronic interactions with the companies it regulates.

Tissue Microarrays - Opening up new opportunities in the Therapeutics sector

Oct 12

Tissue Microarray has become a pivotal cog in the wheel for high throughput studies and is an integral part in the validation process for screening results from discovery platforms for expression studies using various approaches.

De Novo Formula Generation with Sub-ppm Confidence

Oct 12

Novel technology embodied in the micrOTOF allows precise measurement of both accurate mass and True Isotopic Pattern (TIP) over a wide dynamic range, allowing for the implementation of an open access system.

PLA 2.0 Software for Analyzing - Parallel-Line and Parallel-Logistic Assays

Oct 12

Biological or potency assays are frequently analyzed with the help of the parallel-line or parallel-logistic (4 or 5 parameter fit) methods. These methods have major advantages over traditional single-point assays.

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

22 hours ago

Action selection is modulated by external stimuli either directly or via memory retrieval. In a constantly changing environment, animals have evolved attention-like processes to effectively filter the incoming sensory stream. These attention-like processes, in turn, are modulated by memory. The neurobiological nature of how attention, action selection and memory are inter-connected is unknown. We describe here new phenotypes of the memory mutant radish in the fruit fly Drosophila.

Mechanisms of plasticity in simple taxis behaviors in Drosophila

Nov 8

Like the proverbial moth drawn to the candle flame, the fruit fly Drosophila also stereotypically approaches light sources. This positive phototaxis is the archetypal example of hard-wired input-output behaviors.

Live cell imaging of mutant and wild-type GABA-A receptor trafficking using a novel reporter protein

Nov 8

Efficient signaling in the brain requires precise regulation and targeting of cell surface ion-channels. Mutations in these channels associated with inherited diseases can cause improper targeting and reduced surface expression.

ADP-Glo™: An Ideal Approach to Monitor the Activity of Protein Kinases and Beyond

Oct 16

Because of its versatility (alltypesofsubstrates), robustness (Z’>0.8), rapidperformance, and its ease of use, the luminescence based Kinase Glo® assay platform has gained wide acceptance in many drug screening programs for protein kinase inhibitors.

Molecular rotor dynamics influenced by the elastic modulus of polyethylene nanocomposites.

2 hours ago

We observed that the excited-state twisting motion of 3,3(')-diethyloxacarbocyanine in polymer nanocomposites (PNCs) depends strongly on the elastic modulus of medium. PNCs consist of low density polyethylene dispersed with surface-functionalized nanodiamonds...

A conserved interaction between the SDI domain of Bre2 and the Dpy-30 Domain of Sdc1 is required for histone methylation and gene expression.

2 hours ago

In Saccharomyces cerevisiae, lysine 4 on histone H3 (H3K4) is methylated by the Set1 complex (Set1C or COMPASS). Besides the catalytic Set1 subunit, several proteins that form the Set1 complex (Swd1, Swd2, Swd3, Spp1, Bre2 and Sdc1) are also needed to mediate...

Live imaging of rat embryos with Doppler swept-source optical coherence tomography.

2 hours ago

The rat has long been considered an excellent system to study mammalian embryonic cardiovascular physiology, but has lacked the extensive genetic tools available in the mouse to be able to create single gene mutations. However, the recent establishment of rat...

Gefitinib induces apoptosis and decreases telomerase activity in MDA-MB-231 human breast cancer cells.

2 hours ago

Gefitinib is an anti-cancer drug that selectively inhibits epithelial growth factor receptor (EGFR) tyrosine kinase activity and induces apoptosis in many cancer cells. Cancer cells are often protected from apoptotic cell death by telomerase, however the...

Prokariotic Cell Collection in Denmark

Nov 6

I would like to know about a prokariotic cell collection in Denmark. Is there a cell bank in this country? I need a Lactobacillus strain for a fermentation assay and this information about the bank is very helpful for me.
