JM ?Science’s AQV-2200S AQUACOUNTER Karl Fischer Volumetric Titrator features small volume titration cells requiring only 20 mL of titration solvent for accurate measurements. The instrument is suitable for a wide measurement range from 100 ppm to 100% water content.
The promise of stem cell research for drug discovery and cell-based therapies depends on the ability of scientists to acquire stem cell lines for their research. A survey of more than 200 human embryonic stem cell researchers in the United States found that nearly four in ten researchers have faced excessive delay in acquiring a human embryonic stem cell line and that more than one-quarter were unable to acquire a line they wanted to study.
Over the past year, researchers at the California Institute of Technology (Caltech), and around the world, have been studying a group of potent antibodies that have the ability to neutralize HIV in the laboratory; their hope is that they may learn how to create a vaccine that makes antibodies with similar properties. Now, biologists at Caltech have taken one step closer to that goal: They have developed a way to deliver these antibodies to mice and, in so doing, have effectively protected them from HIV infection.
Chemists at Brown University have synthesized a new compound that makes drug-resistant bacteria susceptible again to antibiotics. The compound—BU-005—blocks pumps that a bacterium employs to expel an antibacterial agent called chloramphenicol. The team used a new and highly efficient method for the synthesis of BU-005 and other C-capped dipeptides.
A research team headed by the Georgia Institute of Technology has developed a computer program that can study larger molecules (more than 200 atoms) faster than any other program in existence, helping in pursuit of creating new pharmaceuticals.
The company behind a pioneering stem cell bandage, believed to be the world's first adult and autologous (patient's own) stem cell treatment designed to heal torn meniscal cartilage, can now take the technology to human clinical trials thanks to an investment from one of the U.K.'s most successful entrepreneurs.
The family of complex compounds known as taxanes are exceedingly difficult to produce in the lab, limiting the use of Taxol, an important cancer drug, and hindering the discovery of related taxadienes. Scripps Research Institute scientists have found a way to simplify this process, potentially opening up new drug leads.
Researchers at the University of Copenhagen are behind the development of a new method that will make it possible to develop drugs faster and greener. This will lead to cheaper medicine for consumers.
Sanford-Burnham Medical Research Institute has partnered with Pfizer Inc. as part of Pfizer's commitment to transforming research and development through a focus on translational medicine.
A new partnership between North Carolina State University and Wake Forest Baptist Medical Center will make regenerative medical treatments more quickly available to both human and animal patients.
Using highly potent antibodies isolated from HIV-positive people, researchers have recently begun to identify ways to broadly neutralize the many possible subtypes of HIV. Now, a team led by biologists at the California Institute of Technology has built upon one of these naturally occurring antibodies to create a stronger version they believe is a better candidate for clinical applications.
Among the complex molecular processes involved in the development of bacteria-borne disease is quorum sensing, the way bacteria communicate and coordinate collective behaviors. By studying how to inhibit quorum sensing, scientists may be able create antibacterial pharmaceuticals for a variety of ailments.
A team of researchers at the Massachusetts Institute of Technology has developed a new technology that can measure multiple aspects of individual T cells' responses to HIV-infected cells, including their ability to kill them. The technology could make it easier to monitor and design vaccines against HIV.
Data from a clinical trial involving University of California, Los Angeles researchers suggest that a new therapy may potentially serve as a "functional cure" for HIV/AIDS. The therapy, called SB-728-T, involves the modification of both copies of a patient's CCR5 gene, which encodes the major co-receptor used by HIV to infect immune system cells.
Purdue University is part of a national institute that received a grant of up to $35 million over the next five years from the U.S. Food and Drug Administration (FDA). The FDA awarded the grant to the National Institute for Pharmaceutical Technology and Education, or NIPTE, to improve manufacturing standards and ultimately cut health care costs, create jobs, and improve drug safety.
Researchers at Rutgers University and UMDNJ-Robert Wood Johnson Medical School have determined the structure of a protein that is the first line of defense in fighting viral infections including influenza, hepatitis C, West Nile, rabies, and measles.
Anti-caking agents in powdered products may hasten degradation of vitamin C instead of doing what they are supposed to do: protect the nutrient from moisture. A Purdue University team is studying deliquescence, a reaction in which humidity causes a crystalline solid to dissolve, in hopes to understand how anti-caking agents protect substances such as vitamin C from humidity.
Southwest Research Institute was awarded a $4.4 million contract from the U.S. Department of Health and Human Services Biomedical Advanced Research and Development Authority to develop a nasal-delivery, first-line treatment system to combat cyanide poisoning.
The blood from woolly mammoths—those extinct elephant-like creatures that roamed the Earth in pre-historic times—is helping scientists develop new blood products for modern medical procedures that involve reducing patients’ body temperature.
A team of researchers from the University of Houston and St. Luke’s Episcopal Hospital are working to develop improved screening methods to detect a potentially lethal, drug-resistant superbug that has made its way to Texas.
Chiesi Farmaceutici and NiKem Research have announced details of their extended research collaboration within the respiratory therapeutic area. The current extension involves the period 2011 to 2014 through a multimillion multi-FTE-based service agreement on pre-clinical projects of interest for Chiesi in the repiratory therapeutic area focused on pathologies such as asthma and COPD.
Scientists at Yale University have developed the first practical method to create a compound called huperzine A in the laboratory. The compound, which occurs naturally in a species of moss found in China, is an enzyme inhibitor that has been used to treat Alzheimer's disease in China since the late 1990s and is sold in the U.S. as a dietary supplement to help maintain memory.
Cresset and Redx Pharma announced that they have signed a major drug discovery collaboration, which gives Redx Pharma access to Cresset's computational chemistry technologies for use on their portfolio of drug discovery programs.
In a new study, University of Wisconsin-Madison researchers have described a simple process to separate sugars from a carrier molecule, then attach them to a drug or other chemical.
It is helpful—even life-saving—to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that's easy to read is a challenge. Now, thanks to scientists from the University of Pennsylvania and Duke University, such warning can come in the form of a simple color change.
