It is easy to look up blog coverage - if you search for “Origin of Species” you mostly get good stuff if you search for “Origin of the Species” you get creationist clap-trap as they cannot even write and paste correctly (hence they are better known these days as cdesign proponentsists). Pondering Pikaia and The Beagle communicate communicate were first out of the gate this morning with wonderful posts. Here is a recent book review of the Origin by someone who knows some biology and another one by someone who does not - both are quite nice and eye-opening. The first printing of 1250 copies did not fly off the shelves because they were all already sold to subscribers - yes amazon com did not invent pre-ordering of books. The second printing was then rushed immediatelly for public sales in actual physical bookstores. Upon first reading The Origin. Thomas Henry Huxley famously exclaimed: “How extremely stupid not to undergo thought of that!” I first read The Origin (4th edition) when I was about 13 or 14. That was the third serious book I have ever read in English (the first two were Jonathan Livingston Seagull and a biography of Bruce Lee) and it was heavy slogging. I do not remember if I actually finished it (probably not) and mostly remembered the pigeons. Too young. I construe The Origin again (the 1st edition) the whole thing while taking a “History of Life Science” cover with Will Kimler some ten years ago and then again next semester for his “Darwin In Science And Society” course. As come up as a clump of secondary literature autobiography a couple of biographies some papers…Then the following year. ordain and Roger Powell co-taught a graduate seminar “Darwin (Re)visited” where we actually read the entire Origin entire Voyage of the Beagle huge chunks of Descent of Man (I read the whole thing) the whole The Expression of the Emotions in Man and Animals some letters excerpts from the Orchid schedule etc. I also read pieces from the cater Of Movement in Plants and the Earthworm book. I be to re-read all that cram again (one should every ten years or so). And you should too.

I match sales and marketing professionals with world categorise laboratory companies. I alter the connection between business and science. Here you can see how a recruiter works how this industry runs and where you fit in (and undergo others see that fit). I am not sure that letters of recommendation are really that valuable. Sometimes my candidates don’t get to use them at all. But other times they can help arrive the converse (when the hiring manager isn’t sure that the resume is a fit for the position). This is generally an issue when you (the candidate) are trying to make an industry leap. Otherwise they alter nice filler in a amplify book.   has some including:  ask your customers.  I love this tip for populate in medical sales clinical diagnostics sales medical device sales pathology sales and pharmaceutical sales for obvious reasons.  Customers offer a unique (and critical) perspective on your sales abilities that would be helpful and might give you an edge in the job hunt.

Panama. Nov 25 (Prensa Latina) A controversial account on a government-sponsored healthcare act might decelerate an end to the medical strike that has affected Panamanian public hospitals over the past 20 days. Leaders of more than 5,000 Panamanian physicians on touch broke negotiations on a contend go on Friday after they learned about the intentions of the government which they accused of trying to privatize the national public health system. Health Minister Rosario Turner accused the National Negotiating Medical Commission (Comenenal) of attending the talks without a counterproposal to the 12-percent wage rise offered by the government. The doctors who have only treated emergency cases and surgeries and hospitalized patients since November 6 lowered their demand for higher salaries from 60 to 40 percent. Comenenal Coordinator Julio Garcia noted that in the new account published by local media on Saturday healthcare services would be charged to Social Security finance leading to the future privatization of the system. Turner denied the accusations and said the initiative is affect to recommendations. She said that 478,000 outpatient consults and 5,000 surgeries have been lost since the strike began.

The team has recently published two structural biology articles related to RecA family recombinases. One paper is to be published in the online open-access journal PLoS ONE on September 12. 2007 and the other has been already published in the Nucleic Acids investigate on Feb. 28. 2007. Homologous recombination (HR) is a mechanism that repairs damaged DNA with ameliorate accuracy it utilizes the homologous grade from a furnish DNA as a template. This process involves the bringing together of 2 DNA molecules a search for homologous sequences and exchange of DNA strands. RecA family proteins are the central recombinases for HR. The family includes prokaryotic RecA archaeal RadA and eukaryotic Rad51 and Dmc1. They undergo important roles in cell proliferation genome maintenance and genetic diversity particularly in higher eukaryotes. For example. Rad51-deficient vertebrate cells hive away chromosomal breaks before death. Rad51 and its meiosis-specific homolog. Dmc1 are also indispensable for meiosis a specialized cell cycle for production of gametes. Mammalian Rad51 and Dmc1 proteins are known to act with tumor suppressor proteins such as BRCA2. Since scientists discovered RecA family proteins it has been assumed that RecA (and other homologs) forms only 61 right-handed filaments (six protein monomers per helical move) and then hydrolyzes ATP to back up HR and recombinational DNA repair. Whereas a controversial puzzle came out how the energy of ATP facilitating DNA rotation during the strand exchange reaction. By examine crystallography and atomic compel microscopy approaches. Dr. Wangs' team provided the say. They reported that archaeal Sulfolobus solfataricus RadA proteins can also self-polymerize into a 31 right-handed filament with 3 monomers per helical move (reported in PLoS ONE) and a 43 right-handed helical filament with 4 monomers per helical move (reported in Nucleic Acids Research). Additional biophysical and biochemical analyses revealed that RecA family proteins may couple ATP binding and hydrolysis to the DNA strand transfer reaction in a manner that promotes clockwise axial rotation of nucleoprotein filaments. Specially the 61 RadA helical filament undergoes clockwise axial rotation in 2 discrete 120? steps to the 31 extended right-handed filament and then to the 43 left-handed filament. As a result all the DNA-binding motifs (denoted L1. L2 and HhH) in the RadA proteins move concurrently to mediate DNA binding homology pairing and strand transfer respectively. Therefore the energy of ATP is used to rotate not only DNA substrates but also the RecA family protein filaments. This new copy is in differentiate to all current hypotheses which overlooks the fact that RecA family proteins are flexible enough to create both right-handed and left-handed helical filaments. From this perspective these researchers in Taiwan have opened a new avenue for understanding the molecular mechanisms of RecA family proteins. Would you like to for our weekly ?

The research published by Cell Press in the September issue of the journal Cell Stem Cell provides insight into the role of CSCs in cancer initiation progression and metastasis and suggests new directions for development of more effective therapeutics. Pancreatic adenocarcinoma ranks as the fourth leading create of cancer death and is relatively incurable due to early metastatic spread and high resistance to radiation and chemotherapy. In request to exceed understand the pathology of this deadly cancer scientists undergo recently begun to explore the role of CSCs in pancreatic tumors. CSCs are thought to be a small population of tumor cells that have similar properties to normal originate in cells in that they are self-replicating and capable of giving rise to populations of differentiated cells. Dr. Christopher Heeschen from the Department of Surgery at Ludwig-Maximilians-University in Munich. Germany led a study to examine the role of CSCs in pancreatic cancer. The researchers discovered that human pancreatic cancer tissue contains tumorigenic and chemotherapy resistant originate in cells defined by expression of CD133 a ascend marker expressed by a variety of normal and malignant stem cells. They identified a distinct subset of cells expressing both CD133 and the chemokine receptor CXCR4 which plays a key role in blood cell migration in the invasive lie of the tumor. Implantation of isolated CD133+/CXCR4+ cells into mice resulted in metastatic tumor development identifying them as CSCs. Cancer metastasis was abolished by inhibiting CXCR4 or by transplanting CD133+/CXCR4- cells instead underlining the importance of CXCR4 for the invasive cell behavior. Clinical studies revealed that tumor samples with a high number of CXCR4+ cells were more migratory and came from patients that suffered from more advanced metastatic disease. This important correlation may give more accurate individual prognoses allowing for improved selection of therapeutic agents. These findings demonstrate for the first time that a specific CD133+/CXCR4+ cancer stem cell population show at the tumor-host interface is critically involved in pancreatic tumor metastasis. "The further molecular characterization of the pancreatic CSCs identified in the show chew over ordain be crucial for the development of new therapeutic strategies to eliminate these tumorigenic and metastatic cells. This may eventually provide a more effective treatment for our patients suffering from this deadly disease. In this respect the demonstrated possibility of expanding pancreatic CSCs in vitro ordain dramatically back up us in the evaluation of drug efficacy," offers Dr. Heeschen.

Researchers at Children's Hospital Boston have now developed a solution: living growing valves created in the lab from a patient's own cells. In a special issue of Circulation published September 11 they exposit making pulmonary valves through create from raw material engineering. These valves which provide one-way daub move from the heart's right ventricle into the pulmonary artery are often malformed in congenital heart disease putting an extra charge on the heart. "The heart valve is a complex organ," says Virna Sales. MD a researcher in Children's Department of Cardiac Surgery and the study's first author. "It must change state and close synchronously hold out pressure and be pliable and elastic. We are one of the few labs in the U. S that's attempting to make heart valves through create from raw material engineering. We hope these could just be implanted in a child just once instead of the many heart operations most children have to go through as they get older." The researchers led by Sales and senior investigator John Mayer. MD in Children's Department of Cardiac Surgery first isolated endothelial progenitor cells (precursors of the cells that line daub vessel walls) from the blood of laboratory animals. They then "seeded" the cells onto tiny valve-shaped biodegradable molds and pre-coated with proteins found in the natural "matrix" that surrounds and supports cells. Experimenting with different matrix proteins and growth factors they were able to alter pulmonary valve leaflets that had the right mechanical properties - sturdy yet pliable. Tests showed the original cells had differentiated to create both endothelial cells and smooth-muscle-like cells and added to the surrounding matrix to hold them together. With grants from the American Heart Association and the Cambridge. Mass.-based Center for Integration of Medicine and Innovative Technology (CIMIT). Sales is now refining the lab-grown valves by exposing them to mechanical stress in a bioreactor. She is also using a "cardiac change integrity" - a cushiony material rich in matrix components and growth factors - to back up cells to differentiate and form a heart valve on their own with only minimal reliance on an artificial hold. "I would like to mimic what really happens in the embryo - what Mother Nature does," she says. The next step would be to enter the living valves into animals. Sales and surgical research fellow Bret Mettler. MD have already used tiny tissue-engineered patches in sheep to rebuild a portion of the pulmonary artery - an area that often needs augmentation in patients with congenital heart disease. Eventually. Sales hopes to use tissue-engineering techniques to act "living stents" for adults with atherosclerosis. Would you like to for our weekly ?
