Tour de Sys: The Traveler's View of a Network

christian.thiemann — Fri, 15 May 2009 11:44:04 -0700

Analyzing the structure of complex networks like the US Aviation System can be very difficult, but one way to simplify this problem is to consider only the flights on the shortest routes from one specific airport to every other. For each airport, this gives us a different perspective on the network from which we can examine its statistical properties.

Pigment

schulzbu — Thu, 14 May 2009 21:25:05 -0700

The video is based on an experiment of a Plant physiology course (HORT301) for Horticulture and Biology students. It is a student production geared towards middle school, highschool students and undergraduates as well as viewers who are interested in plant science. It depicts how flower pigments are analyzed using thin layer chromatography (TLC) and spectrophotometry. Investigations that shed light on the chemical and physical behavior of flower pigments are also shown as the isolated pigments are subjected to different pH and the change in spectral behavior (change of color) is monitored.

PSI-Are my soybeans wearing different genes?

schulzbu — Thu, 14 May 2009 20:14:01 -0700

The video PSI – Are my soybeans wearing different genes? is inspired by the popular TV show “CSI-crime scene investigations”. Here, however, the investigators are solving cases in the field of plant science investigations (PSI). The stunning phenomenon that soybean plants can survive herbicide treatments and grow on fields without weed competition is investigated using DNA extraction, Polymerase chain reaction (PCR), gene analysis etc. Transgenes are found that make the soybean plants herbicide resistant.

Obama Inauguration: A Positive Change in Federal Stem Cell Research Policies

CIRMTV — Thu, 14 May 2009 14:15:41 -0700

On March 9, 2009, President Barack Obama signed an executive order to lift a ban on federal funding for embryonic stem cell research that had been in place since August, 2001. In this video, Susan Fisher, director of the UCSF Human Embryonic Stem Cell Center, and Alan Trounson, president of the California Institute for Regenerative Medicine, discuss how the federal ban affected stem cell researchers and how President Obama's stem cell research policies will bring new opportunities in this field.

Jerome Zack Talks About Creating iPS Cells

CIRMTV — Thu, 14 May 2009 13:51:10 -0700

In 2006 scientists learned how to create a pluripotent stem cell out of a human skin cell. These cells, called induced pluripotent stem (iPS) cells have many of the characteristics of embryonic stem cells including the ability to create mature cell types. Dr. Jerome Zack has a CIRM grant to create iPS cells that could be used in human therapies. Zack is Associate Director, UCLA AIDS Institute, professor of Medicine, Microbiology, Immunology & Molecular Genetics, and a scientist with the Eli and Edythe Broad Center of Regenerative Medicine and Stem cell Research at UCLA.

Embryonic stem cells have the potential to help treat 70 or more diseases, but developing those new therapies will take time. Alan Lewis is president and CEO of Novocell, a La Jolla-based company that has been developing a potential therapy for diabetes. Novocell has a CIRM grant to assemble a team of researchers who will accelerate the time it takes to get that potential therapy to the FDA for clinical trials.

Mark Mercola: Differentiating Embryonic Stem Cells into Adult Tissues

CIRMTV — Wed, 13 May 2009 15:57:56 -0700

A major challenge in developing stem cell-based cures for disease is maturing those cells into adult cell types that can be used for transplantation or to study human disease. Mark Mercola has a CIRM grant to derive heart muscle cells from embryonic stem cells. In this video, Dr. Mercola describes how stem cells could one day be used for transplantation, for testing new drugs for side effects on heart muscle cells, and to learn about how the heart cells mature and develop. That knowledge could lead to new drugs to help the heart repair itself after a heart attack.

Novel Spinal Cord Stimulator Sparks Hope for Parkinson’s Disease Treatment

Duke Medical Center News — Mon, 11 May 2009 13:54:46 -0700

Content: The future treatment of Parkinson’s disease may target the spinal cord instead of the brain to help alleviate the slow, rigid movements and tremors that are the hallmarks of the disease. Researchers at Duke University Medical Center have developed and tested a first-of-its-kind device that rapidly restored motor function in mice with the symptoms of Parkinson’s disease.

Amgen would like to invite healthcare professionals to visit http://angiogenesis.amgen.com, where the science of angiogenesis comes to life. Angiogenesis, a fundamental mechanism in normal development and cancer, involves multiple cellular regulators that include the angiopoietins, the VEGF family and other regulators. Amgen has developed an interactive website that will provide users with a cinematic experience through which to view the process of tumor vessel growth. This video is one of many featured on this site.

Cdc42 controls spindle orientation to position the apical surface during epithelial morphogenesis

JCB — Wed, 22 Apr 2009 11:24:02 -0700

The establishment of apical–basal polarity within a single cell and throughout a growing tissue is a key feature of epithelial morphogenesis. To examine the underlying mechanisms, the human intestinal epithelial cell line Caco-2 was grown in a three-dimensional matrix to generate a cystlike structure, where the apical surface of each epithelial cell faces a fluid-filled central lumen. A discrete apical domain is established as early as the first cell division and between the two daughter cells.

One-Dimensional Topography Underlies Three-Dimensional Fibrillar Cell Migration

JCB — Wed, 22 Apr 2009 10:35:31 -0700

Current concepts of cell migration were established in regular two-dimensional (2D) cell culture, but the roles of topography are poorly understood for cells migrating in an oriented 3D fibrillar extracellular matrix (ECM). We use a novel micropatterning technique termed microphotopatterning (µPP) to identify functions for 1D fibrillar patterns in 3D cell migration. In striking contrast to 2D, cell migration in both 1D and 3D is rapid, uniaxial, independent of ECM ligand density, and dependent on myosin II contractility and microtubules (MTs).

Collective cell migration requires vesicular trafficking for chemoattractant delivery at the trailing edge

JCB — Wed, 22 Apr 2009 09:38:09 -0700

Chemoattractant signaling induces the polarization and directed movement of cells secondary to the activation of multiple effector pathways. In addition, chemotactic signals can be amplified and relayed to proximal cells via the synthesis and secretion of additional chemoattractant. The mechanisms underlying such remarkable features remain ill defined. We show that the asymmetrical distribution of adenylyl cyclase (ACA) at the back of Dictyostelium discoideum cells, an essential determinant of their ability to migrate in a head-to-tail fashion, requires vesicular trafficking.
