Queen Elizabeth II Celebrates Diamond Jubilee Anniversary, 60 Years on British Throne


Queen Elizabeth II marks her Diamond Jubilee anniversary today.

The British royal family matriarch, 85, marks 60 years as queen, and on this date, she dedicated herself anew to continuing to serve Britons and those around the world.

A new set of portraits of Elizabeth and her husband Prince Philip, taken by John Swannell in the Centre Room at Buckingham Palace in December 2011, have been released to commemorate the occasion. Take a look:

Elizabeth said that while has seen "great advances" since she took over following her father George VI's death on February 6, 1952, she is looking forward to the future with a "clear head and warm heart."

The comments came after a day in which she and husband, 90, attended a church service in Norfolk, to the delight of flower-clasping well-wishers..

In her message, which was released by Buckingham Palace, Elizabeth said:

"I hope that we will all be reminded of the continued power of togetherness ... convening strength of family, friendship and good neighborliness, examples of which I have been fortunate to see throughout my reign."

Elizabeth is the mother of Prince Charles and the grandmother of Prince William, the two next in line to succeed her at the helm of the British monarchy.

Selma Blair, Shawnee Smith join Charlie Sheen's TV series (Reuters)

LOS ANGELES, Feb 3 (TheWrap.com) ? Charlie Sheen has just lined up two more goddesses for his harem -- on the small screen, at least.

Selma Blair and Shawnee Smith have been cast in Sheen's upcoming adaptation of the 2003 Jack Nicholson/Adam Sandler film "Anger Management." "Cruel Intentions" star Blair will play Sheen's therapist and potential love interest. Shawnee Smith, who played ditzy assistant Linda on the Ted Danson sitcom "Becker," will play his ex-wife.

Smith coyly tweeted: "My sweet and loyal friend and fans... I can finally "officially" tell you I am back in the half hour comedy business:)"

The series will run on FX, with an initial order of 10 episodes, with the possible addition of 90 more episodes if it succeeds.

Sheen, who was ousted from the CBS hit "Two and a Half Men" last year following a run of bizarre behavior, will have a "significant ownership stake" in the series.

What You Need to Know Before Refinancing - Cheryl Scott-Daniels ...

During his State of the Union address?last?Tuesday, President Barack Obama called on Congress to approve new legislation that would give all homeowners who are current on their mortgages the opportunity to refinance at record-low mortgage rates.

While details of the program have yet to emerge, the new legislation - in theory - is designed to give responsible homeowners a reasonable chance to refinance without running into roadblocks from lenders. This would also give homeowners an opportunity to take advantage of today?s continued, record-low interest rates.

According to CoreLogic, a company that tracks national mortgage activity, an estimated 28 million homeowners could cut the interest rates on their loans by more than one percentage point if they could refinance. If you?re one of the many homeowners considering a refinance, here are some important facts you need to know first. Be sure to consult with your real estate agent and/or financial advisor, as well.

  1. Make sure you are in good standing on your mortgage. As the President emphasized, refinances will be considered for those homeowners who have a good payment history and are current on their mortgages. If you?re currently underwater, a refinance is probably not an option for you. Consult your real estate professional about other options, including loan modifications and short sales.
  2. Check your current credit score. Refinance candidates need to demonstrate steady income and good credit. Make sure your credit rating is up to snuff and see what immediate measures can be taken to improve it if it?s not.
  3. Examine how much longer you plan to live in your home. If you are planning to put your home on the market in the near future, refinancing probably doesn?t make sense. You need to make sure you?ll be living in your home long enough to recoup the closing costs of the refinance.
  4. Consider the length of the loan. Where you?re at with your current mortgage can play a significant role in your decision to refinance. If you?re close to retirement, for example, and your loan is almost paid off, refinancing could result in extending the life of your loan, ultimately costing you more. Also, if you're several years into a 30-year mortgage, your goal should be to refinance into a 15- or 20-year mortgage instead. Otherwise, you?re extending the number of years in which you?ll pay interest. Your refinancing goals should be short-term and long-term savings.
  5. Find out the costs involved. Before you plunge into a refinance, find out the costs involved. Weigh these fees against the money you will save (contingent upon how long you plan to stay in your home) to make sure refinancing is the right step.

Experiment on Cultivation and Identification of Colorectal Cancer ...

[Abstract]

Background and Objective:Recent studies have shown that a rare population of undifferentiated cells are responsible for tumour formation and maintenance, they express definite cell surface markers and possess some differentiation potential. In vivo xenograft transplantation assay,they show high tumorigenic potential, so they are defined as cancer stem cells. Further study show that the features of self-renewal and differentiation potential they possess are preserved and regulated by microenvironment such as tumor stroma cells and vascular endothelial cells. They also express drug resistance protein, more efficient at repairing of damaged DNA, so they can resistant to drug and radiation. Thus cancer stem cells are the root of cancer,and responsible for cancer metastasis,recurrence and drug resistance. Similar studies have shown that subpopulations of tumor cells from blood, breast, brain, pancreas and colon.Cancer cell line is seen as classic model for studying cancer. There are certain progress in the study of cancer stem cells about cancer cell line since Toru Kondo has been found that cancer stem cells persist in many cancer cell lines, but only limited to glioma and breast cancer cell line. Zhu found that spheres could isolated from glima cell line under serum-free culture condition containing growth factor, those spheres were enrich in cancer stem cells, so he called them brain tumor spheres. As so far, the report about cancer stem cells in colorectal cancer cell line is rare. Therefore we choose colorectal cancer cell line Colo205 as research objective and aim to study how Colo205 generate colorectal cancer sphere under special culture condition, and identify its biological characteristics. Colo205 cell line was established in 1975 by Toni U. Semple, from ascitic fluid of a 70-year-old Caucasian male with carcinoma of the colon. It growth property is mixed with adherent and suspension.Methods:1. Culture colorectal cancer sphere Serum-free medium(SFM) contains B27, epidermal growth factor(EGF), basic fibroblast growth factor(bFGF), Leukemia inhibitory factor(LIF) and glutamine.Colo205 cells were cultured in SFM,while routine Colo205 cells cultured in 1640 medium containing 10% fetal bovine serum were as control. Observe the process of Colo205 cells generating colorectal cancer spheres and detect expressions of intestal stem cells marker Musashi-1 by immunocytochemical.2. Differentiation assay Colorectal cancer spheres were cultivated without EGF and bFGF in the presence of 10% serum to induce to differentiation. Cells morphology were observed by optical microscope. Then we collected cells from colorectal cancer spheres, post-differentiated sphere cells and routine Colo205 cells, and labeled anti-CD44-FITC and anti-CD133-PE antibody respectively, and analysed expressions of stem cell surface markers CD133 and CD44 among them by flow cytometry.3. Cell cycle analyse We collected colorectal cancer spheres and routine Colo205 cells, and labeled PI after adjusting to the same concentration, then we compared cell cycle between two groups by flow cytometry.4. Spectral karyotype analyse We collected colorectal cancer spheres and routine Colo205 cells, spectral karyotype was performed on tumor metaphase cells after adjusting to the same concentration, and then made statistical analysis on the number of Chromosomes.5. Three-dimensional culture When typical Colorectal cancer spheres were generated, we mechanically and enzymatically dissociated into a single-cell suspension, and changed the medium into medium containing serum, and adjusted to the concentration of 60000/ml, while the same concentration of routine Colo205 cells were as control. Three-dimensional culture was conducted using Matrigel matrix, then we observed how spheres differentiate into crypt-like structures.6. Detect sternness genes by RT-PCR We extracted RNA of colorectal cancer spheres and routine Colo205 respectively, and then we synthesised cDNA and second strand DNA consecutively. Semi-quantitative PCR detected the expression of Bmi-1 and Notch-1.7 . Xenograft transplantation assay After having set up multiple concentrations, we compared tumorigenic capacity between the two groups at the same concentration. Then transmission electron microscope observation, Haematoxylin-eosin analysis and Immunohistochemical analysis of xenograft were conducted.Results:1. Colo205 could survived in serum-free medium containing growth factor, when cultured at 7 day, most of adherent cells were apoptosis, a rare population of cells could survived , proliferated and formed the suspended colorectal cancer spheres. The spheres can generate serially passaged spheres, demonstrating their self-renewal feature. When changed the serum-free medium into the medium containing serum, we observed that the cells in sphere migrate out of it and formed single-cell layer after 10 days. We also found that colorectal cancer spheres were high expression of intestinal stem cells marker Musashi-1, while routine Colo205 cells did not express Musashi-1.2. The proportions of CD133~+, CD44~+, CD44~+CD133~+ cells in routine Colo205 cells were (13.27?5.62)% ,(62.92?8.38)% and (10.77?4.96%) respectively,while the three indicators in colorectal cancer spheres were (52.71?16.97)%, (79.06?12.10)% and (46.89?19.17%) respectively, three indicators for post-differentiated cells were (16.47?2.45)% ,(47.80?2.57)% and (12.41?2.27%) respectively. There were statistical difference between the groups, and F values were 17.517,10.752,12.294 respectively, P values were 0.001,0.003,0.002 respectively, the proportion of CD133~+, CD44~+, CD44~+CD133~+ cells in colorectal cancer spheres were significantly higher than post-differentiated cells and routine Colo205 cells (P 0.05):3. The proportion of routine Colo205 cells in G1 phase was (73.8?2.9)%, and (26.2?2.9%) for S/G2 phase, while the proportion of colorectal cancer spheres in G1 phase was (51.9?1.6)%, and (48.1?1.6%) for S/G2 phase. The proportion of cells in S/G2 phase was significantly higher in colorectal cancer spheres than in routine Colo205 cells (P = 0.000), indicating that colorectal cancer spheres were in a high-proliferation state.4. We could not find any noticeable difference in the number of chromatosomes between the colorectal cancer spheres and the routine Colo205 cells(P=0.070), and the two groups were all of aneuploidy.5. The typical crypt-like structures were emerged in 18 days, a cell-ring interconnection structure and overlap upward growth trend was formed in colorectal cancer spheres group, while the control group did not formed any crypt-like structure, with cells stopping proliferation. Those demonstrated that colorectal cancer spheres had a strong proliferation and differentiation potential, while routine Colo205 cells only had limited cell proliferation potential and without any differentiation potential. When at day of 18, the numbers of crypt-like structures in routine Colo205 cells group was 0 at one level, while the number in tumor spheres group were (8.6?1.1). 95% confidence interval was [7.184, 10.016], and it did not contain 0, then we can see that the difference was significantly.6. Semi-quantitative RT-PCR analysis found that expressions of Bmi-1 and Notch-1 in tumor spheres were significantly higher than the control group (P value were 0.002 and 0.031 respectively ), indicating that colorectal cancer spheres had a strong self-renewal capacity.7. Xenograft transplantation assay showed that 104 colorectal cancer sphere cells were tumorigenicity, while the same number of routine Colo205 cells did not. The volume of tumor generated by 105 colorectal cancer sphere cells was significantly larger than the control group, indicating that colorectal cancer spheres were high tumorigenicity. HE analyse found similar differentiation structure between the two groups, and intestinal stem cells Musashi-1 -positive cells were similar between two groups of xenograft, and similar malignant phenotypes were found by transition electron microscopy in both of two xenografts. This suggested that in spite of the number of cancer stem cells that implantated in mice between two groups are vary greatly, once they initiated the foundation of tumor growth in mice, and in the active of basement membrane elements, same cytokines and vascular endothelial cell which induce to differentiation, the final of tissue structure, degree of differentiation and degree of malignancy are similar, showing that colorectal cancer stem cells possess the self-renewal and differentiation capacity in vivo.Conclusion:1. There were a small population of cancer stem cells persist in Colo205 cells. Colorectal cancer spheres in which enrich cancer stem cells can be generated under serum-free culture condition with EGF and bFGF.2. Colorectal cancer spheres are high expression of cancer stem cell marker CD133, CD44, when they were induced to differentiation by adding serum, the expression of both markers were markedly decrease. We first discovered and identified CD44 as a useful colorectal cancer stem cell marker at home and abroad.3. Colorectal cancer stem cells possess infinite self-renewal and certain differentiation potential in vitro,and high expression of sternness gene Bmi-1 and Notch-1. In three-dimensional culture they can be differentiated into ?crypt-like? structure.4. Colorectal cancer stem cells are more tumorigenic than routine Colo205 cells.

Stimulation of brain hormone action may improve pneumonia survival

Tuesday, January 31, 2012

An international research team may have found a way to block a second wave of death that can result from pneumonia treatment.

Antibiotics are effective at killing pneumococcus ? the cause of about 50 percent of pneumonias ? but as it dies the bacterium releases potentially lethal toxins.

Adding an agonist that mimics the action of growth hormone-releasing hormone ? which ultimately enables growth ? may stop that second wave, according to research published in the Proceedings of the National Academy of Sciences.

"You have to take antibiotics, if you don't, the bugs will grow and you most likely will die anyway," said Dr. Rudolf Lucas, vascular biologist at the Medical College of Georgia at Georgia Health Sciences University.

Problems start when a bacterium that causes pneumonia, in this case pneumococcus, is inhaled. Symptoms include mucus buildup, cough, fever, chills and shortness of breath. Antibiotics are the front line treatment to kill the infection.

An unfortunate result of bacterium death is release of pneumolysin, a toxin that can trigger formation of holes in the walls of the millions of tiny air sacs and blood vessels in the lungs. The result is that fluid, blood and other products find their way into air sacs that were intended for oxygen exchange.

"It's like making a hole in a bucket," said Lucas. He and Dr. Andrew V. Schally, Distinguished Leonard M. Miller Professor of Pathology & Professor of Hematology/Oncology at the University of Miami Miller School of Medicine, are co-corresponding authors on the study.

Pneumolysin naturally binds to cholesterol, a component of all cell membranes including cells lining the air sacs, or alveoli. Once attached to the membrane, the toxin produces complexes that make holes in the membranes of the air sacs before escaping to do similar damage to nearby capillaries. While the close proximity of capillaries normally enables air sacs to replenish blood with oxygen and to remove carbon dioxide, the now open exchange enables fluid and cells from the capillaries to penetrate air sacs as well as the space in between them. To make matters worse, the toxin also blocks a protective sodium uptake system in the lungs that can help remove fluids. Within a few days, the patient is back in jeopardy. "These patients are being treated with an antibiotic and aggressive intensive care support and they (can) still die," Lucas said.

Schally, a Nobel Prize recipient for his discovery of hypothalamic hormones and Head of The Endocrine, Polypeptide and Cancer Institute, Veterans Affairs Medical Center in Miami, developed the agonist that may one day make the difference for these patients. The agonist was previously shown to help protect heart muscle in the aftermath of a heart attack.

Surprisingly, GHSU scientists detected receptors for growth hormone releasing hormone in cells lining the air sacs. Typically, growth hormone-releasing hormone is produced by the hypothalamus then goes to the pituitary which makes and releases growth hormone. "We were asking ourselves, what is it doing there?" Lucas said.

They got a clue when they applied the agonist to the growth hormone-releasing hormone in an animal model of pneumonia as well as human lung cells in culture: leaking was significantly reduced and beneficial sodium uptake was restored. Conversely, when they applied a hormone antagonist ? to block its action ? lung cells became leaky even without toxin exposure, further indicating the hormone's apparent role in protecting the lining of the air sacs and capillaries.

"This is an acute problem; dangerous lung fluid accumulation occurs within days in patients," said Lucas who anticipates the agonist, or a compound with a similar function, could someday be given to patients in those first few critical days to avoid the second onslaught.

As a result of the findings, extensive collaborative studies are being planned on the use of growth hormone-releasing hormone agonists to prevent edema in patients with bacterial pneumonia. Next steps include pursing a National Institutes of Health grant with Dr. Michael A. Matthay, Senior Associate, Cardiovascular Research Institute, University of California, San Francisco, to support more studies that include an isolated human lung model and a preclinical model of laboratory animals who follow the same course as patients: they are infected with the bacterium then given an antibiotic. In the model for the PNAS study, scientists gave the resulting toxin directly.

Dr. Trinad Chakraborty, Dean of the Faculty of Medicine at the University of Giessen in Germany, developed the purified toxin used for the study. Study co-authors Dr. Richard White, GHSU pharmacologist, showed restoration of sodium uptake, and Dr. Supriya Sridhar, GHSU research associate, performed the cell permeability experiments. University of Miami co-authors included Dr. Norman L. Block, Professor of Pathology, Urology, Oncology and Biomedical Engineering, as well as Dr. Ferenc G. Rick, Assistant Research Professor of Pathology.
