IgA nephropathy in two patients with Sjögren's syndrome: one with concomitant autoimmune hepatitis.

Concurrent glomeruli and liver involvement in patients with Sjögren's syndrome (SS) has seldom been reported. Meanwhile, IgA nephropathy (IgAN) associated with SS is not as common as other types of glomerulonephritis, such as membranoproliferative glomerulonephritis (MPGN) and...

Excitatory actions of substance P in the rat lateral posterior nucleus.

Abstract The lateral posterior nucleus (LP) receives inputs from both neocortex and superior colliculus (SC), and is involved with integration and processing of higher-level visual information. Relay neurons in LP contain tachykinin receptors and are innervated by substance P...

What price access to the open seas? The geopolitics of oil and gas transmission from the Trans-Caspian republics

In the late 1980s, the Soviet Union was the world's largest hydrocarbon producer. The landmass over which these resources are distributed is vast and the reserves mostly landlocked. To convey these hydrocarbons to refineries and to market, the Soviets constructed the largest...

Is Los Angeles-Style Sprawl Desirable?

This article reviews the literature on characteristics, causes, and costs of alternative development patterns. In doing so it debunks arguments by Gordon and Richardson in favor of Los Angeles-style sprawl. Sprawl is not suburbanization generally, but rather forms of suburban...

Cow preference and usage of free stalls compared with an open pack area.

Free-stall housing systems are designed to provide a comfortable and hygienic lying area, but some aspects of stall design may restrict usage by cows. The aim of this study was to compare free-stall housing with a comparable lying area (open pack) without stall...

Palaeoecological interpretations of South Australian Precambrian stromatolites

Despite the palaeoecological emphasis of recent stromatolite research outside the USSR, controversy still exists regarding the environmental restriction of these organosedimentary structures and some analogies with modern occurrences have been maintained too rigidly....

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.

Step up to the MIQE

Mar 30 2010

Over the years, polymerase chain reaction (PCR) has evolved into a readily automated, high throughput quantitative technology. Real-time quantitative PCR (qPCR) has become the industry standard for the detection and quantification of nucleic acids for multiple application, including quantification of RNA levels. But a lack of consensus among researchers on how to best perform and interpret qPCR experiments presents a major hurdle for advancement of the technology. This problem is exacerbated by insufficient experimental detail in published work, which impedes the ability of others to accurately evaluate or replicate reported results.

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.
