Finding a Cure for Spinal Cord Injury with On-Demand LIMS
Oct 25
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
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
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.
HP Scalable Network Storage Systems for Life Sciences
Sep 13
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
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.
Fast Optimization of a Multiplex Influenza Identification Panel Using a Thermal Gradient
The year 2009 was marked by the emergence of a novel influenza A (H1N1) virus that infects humans. There is a need to identify the different strains of influenza virus for purposes of monitoring the H1N1 strain pandemic and for other epidemiological and scientific purposes.
Advantages of Monolithic Laser Combiner Technology in Confocal Microscopy Systems
Jan 6
Fluorescence microscopy techniques require a reliable light source at the desired wavelength or wavelengths, with minimal downtime for maintenance and alignment. Lasers are a popular light source, although the alignment and upkeep of laser combiners is a time-consuming prospect for many users.
Using the Tecan Genesis Workstation to Automate a Cytometric Bead Array (CBA) Immunoassay
Mar 11
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
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
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
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.
Comfrey (Symphytum Officinale. L.) and Experimental Hepatic Carcinogenesis: A Short-term Carcinogenesis Model Study.
Nov 13
Comfrey or Symphytum officinale (L.) (Boraginaceae) is a very popular plant used for therapeutic purposes. Since the 1980s, its effects have been studied in long-term carcinogenesis studies, in which Comfrey extract is administered at high doses during several...
Type II muscle fibers atrophy associated with silent corticotroph adenoma in a dog.
The Silent Corticotroph Adenoma (SCA) is a pituitary adenoma variant characterized by the immunoreactivity for adrenocorticotropic hormone (ACTH) and related peptides, without the clinical signs of Cushing's disease. SCA has been postulated to either secrete...
Assessment of S100 protein expression in the epididymis of juvenile and adult European bison.
In our study, we decided to compare S100 protein expression in the material obtained from the epididymes of 5- and 12-month-old calves, and adult European bison, and to detect any differences in S100 expression according to the animal age and size of the organ...
Immunohistochemical detection of dopamine D2 receptors in human pituitary adenomas.
Thirty one pituitary adenomas and 3 samples of peritumoral anterior pituitary tissue were immunostained with an antibody raised against dopamine D2 receptor protein. The positive reactions were found in cell cytoplasm, a subpopulation of cell nuclei and the...
