Johnson & Johnson says it has received federal approval to sell a new type of blood thinner that reduces deadly blood clots in patients who have received knee and hip replacements.

The company's drug, rivaroxaban, is the first Food and Drug Administration-approved medicine that works by blocking a clotting protein called factor Xa. Many older blood thinners work by preventing platelets from sticking together.

J&J's pill will serve as an alternative to Sanofi-Aventis SA's popular injection Lovenox, which is the standard treatment for patients who have undergone orthopedic surgery.

More than 800,000 such surgeries are performed each year in the U.S. Dangerous blood clots in the leg arteries are a frequent side effect of the procedure, as inflammation prevents recovering patients from walking for extended periods of time.

J&J is based in New Brunswick, N.J.

The Miami Project to Cure Paralysis finds an on-demand laboratory information management system (LIMS) helps to accelerate discovery in its HCS projects.

Saving Cells: Image Processing for Improved Viability, Part II: Iterative Deconvolution

Oct 25 2010

3D light microscopy and deconvolution provide a means to investigate 3D structure, providing near-confocal quality images without the temporal requirements or potentially damaging phototoxicity associated with other 3D imaging technologies. This article is Part II in a series regarding viability, resolution improvement, and measurement in fluorescence imaging. Part I focused on spectral unmixing.

Sep 22 2010

This article is Part I of a two-part series regarding viability, resolution improvement, and measurement in fluorescence imaging. Part II will focus on deconvolution.

Evaluation of a New Nano-Type UV-Vis Spectrophotometer

Mar 3

Analysis of one- to four-microliter size samples for nucleic acids has become routine in many life science laboratories. However, until now, available instruments require considerable manipulation of the instrument and sample; some require manually recording the data. The user must typically lower and raise the arm manually, then wipe the sample manually from the target after each analysis. And fiberoptics used in some of these instruments are subject to deterioration.

Production of Recombinant Proteins and Monoclonal Antibodies in Hollow Fiber Bioreactors

Jan 25

While well-understood, robust and convenient, classical batch-style 2-D culture on non-porous supports or 3-D suspension culture in other devices are really not very biologically relevant models. Cell culture conditions can affect the quality of the antibody or protein produced.

Selecting Robots for Use in Drug Discovery and Testing

Dec 6 2010

Drug discovery and testing, with their need for speed, repeatability and verification, are ideally suited to benefit from robot automation. It is therefore not surprising that robots have been at the forefront of automation developments in both these areas.

HP Scalable Network Storage Systems for Life Sciences

Sep 13 2010

Life sciences research today is advancing exponentially, each step bringing us closer to the realization of truly personalized medicine–preventive care and treatments designed specifically for each individual. In the near future, PCPGM healthcare researchers expect to be able to use predictive genetic testing to create custom treatment plans for individuals and deliver dramatic improvements over today’s one-size-fits-all approach. But research capabilities are only part of the equation; current storage and operating capacities must also evolve to accommodate ever-expanding amounts of data before the goal of personalized medicine can be realized.

Using the Tecan Genesis Workstation to Automate a Cytometric Bead Array (CBA) Immunoassay

Mar 11 2010

The poster describe the process involved in automating a Cytometric Bead Array (CBA) immunoassay developed to measure relative concentrations of serum antibodies against Tetanus (TT), Sperm Whale Myoglobin (SWM) and Keyhole Limpet Hemocyanin (KLH) in KLH-immunized volunteers.

Ensuring Quality in Assays Performed with Automated Liquid Handlers

Feb 2 2010

The focus of this presentation is to highlight the need of ensuring quality in important assays performed with automated liquid handlers. Nearly all assays performed within a laboratory are volume-dependent. In turn, all concentrations of biological and chemical components in these assays, as well as the associated dilution protocols, are volume-dependent. Because analyte concentration is volume-dependent, an assay’s results might be falsely interpreted if liquid handler variability and inaccuracies are unknown or if the system(s) go unchecked for a long period.

Inkjet System for Protein Crystallography

Feb 1 2010

X-ray crystallography is used routinely by scientists to obtain the three dimensional structure of a biological molecule of interest.Such information can be used to determine how a pharmaceutical interacts with a protein target and what changes might improve functionality. However, the crystallization of macromolecules still remains a serious hindrance in structural determination despite impressive advances in screening methods and technologies.

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Nov 9 2009

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.
