In their study, at least 1 in 3 individuals with oropharyngeal cancer had antibodies to HPV, compared to fewer than 1 in 100 individuals without cancer. When present, these antibodies were detectable many years before the onset of disease. …
Prins presented her findings at the ENDO 2013 meeting in San Francisco June 17. "This is the first direct evidence that exposure to BPA during development, at the levels we see in our day-to-day environment, increases the risk for prostate cancer in human prostate tissue," said Prins, professor of physiology and director of the andrology laboratory in urology at the UIC College of Medicine. The increased risk can be traced to prostate stem and progenitor cells which become "sensitized" to estrogen early in development through exposure to BPA — which mimics estrogen in the body. …
Efforts to make this treatment possible have been limited by a dearth of insulin-producing beta cells that can be removed from donors after death, and by the stubborn refusal of human beta cells to proliferate in the laboratory after harvesting. The new technique uses a cell conditioning solution originally developed to trigger reproduction of cells from the lining of the intestine. "Until now, there didn’t seem to be a way to reliably make the limited supply of human beta cells proliferate in the laboratory and remain functional," said Michael McDaniel, PhD, professor of pathology and immunology…
Melanoma is a tumor affecting melanocytes, skin cells that produce the dark pigment that gives skin its color. The disease is responsible for approximately 75 percent of skin cancer deaths, with chances of survival directly related to how early the cancer is detected. Current detection methods most commonly rely on visual inspection of the skin, which is highly dependent on individual self-examination and clinical skill. The current study took advantage of the fact that human skin produces numerous airborne chemical molecules known as volatile organic compounds, or VOCs, many of which are odorous. …
Sarah Murnaghan, the 10-year-old Pennsylvania girl dying of cystic fibrosis, is receiving her long-awaited lung transplant. According to a Facebook post from Sarah’s mother, Janet, the family received word this morning of new lungs that had been made available, and Sarah is currently in surgery.  The operation will take many hours. A spokeswoman from the Children’s Hospital of Philadelphia (CHOP), where Sarah has been hospitalized, said they do not have any information to release. In the Facebook post, Janet said the family is overwhelmed with emotions, and she thanked everyone for their unending support.  She also asked her followers to pray for Sarah's donor. “Please pray for Sarah's donor, her HERO, who has given her the gift of life,” Janet Murnaghan wrote. “Today their family has experienced a tremendous loss, may God grant them a peace that surpasses understanding.” United States Senator Pat Toomey (R-Pa.) released the following statement after being informed by the family of Sarah’s good news: “I am deeply grateful to the organ donor and his or her family for the potentially life-saving gift to Sarah. Now that a suitable donor has been found, a prayer would help, too - a prayer Sarah's body accepts the new organ the way doctors believe it can. The judge gave Sarah a chance to receive a new lung.  Now the surgical team at CHOP is giving her a chance at life.”   Sarah has been in desperate need of a lung transplant for the past 18 months.  She has been hospitalized at Children’s Hospital of Philadelphia for the past three months, where she has been on a ventilator. Under the current guidelines for organ donation, children under the age of 12 must wait for pediatric lungs to become available.  Adult lungs cannot be offered to children under 12, until they are offered to adults and adolescents first.   The Murnaghans have been in the midst of a legal battle over the established rules for organ donation after they filed a lawsuit last week to have the guidelines changed, arguing the rule keeping Sarah off the list was “discriminatory.” A federal court judge granted a temporary order on June 5 that allowed Sarah to join an adult organ transplant list. It is not yet clear whether Sarah’s donor is an adult or a child. Judge Michael Baylson made his ruling after hearing oral arguments on the case and had scheduled a preliminary injunction hearing for June 14. Baylson's order told Department of Health and Human Services (HHS) Secretary Kathleen Sebelius to direct the group that manages the organ transplant list to cease application of it in Sarah's case. Secretary Sebelius declined to intervene in the case early last week, despite urgent pleas from several members of Congress from Pennsylvania. Sebelius said that such decisions should be made by medical experts and noted that there were three other children at Children's Hospital alone in the same condition. Over the weekend, Sarah's condition worsened, and she was intubated on Saturday after she experienced additional trouble breathing.

"Given that such testing can provide many options to enable individuals to manage their cancer risk, it is vital to encourage awareness and acceptance among both the public and medical professionals," he will say. "For example, removal of the ovaries in women over 40 years old who carry a BRCA mutation decreases their overall cancer mortality by 20% and prophylactic mastectomy can reduce the chances of breast cancer in women carrying such a mutation by around 90%…
Both the Centers for Disease Control and Prevention (CDC) and the American College of Pediatrics now recommend that both girls and boys be vaccinated against HPV. Robert I. Haddad, MD, disease center leader of Dana-Farber Cancer Institute’s head and neck oncology program, says the recommendations are well founded…
Using the bacterium E. coli, researchers from the University’s Faculty of Engineering showed it was possible to vastly increase the efficiency of the cells producing specifically modified proteins, as well as improve its performance and stability. The modification is present in over two-thirds of human therapeutic drugs on the market and involves the addition of specific sugar groups to the protein backbone, a process termed glycosylation. Drugs based on proteins are increasingly important in modern medicine to tackle health problems including diabetes, cancer and arthritis. …
For decades, health officials have battled malaria with insecticides, bed nets and drugs. Now, scientists say there might be a potent new tool to fight the deadly mosquito-borne disease: the stench of human feet. In a laboratory study, researchers found that mosquitoes infected with the tropical disease were more attracted to human odors from a dirty sock than those that didn't carry malaria. Insects carrying malaria parasites were three times more likely to be drawn to the stinky stockings. The new finding may help create traps that target only malaria-carrying mosquitoes, researchers say. “Smelly feet have a use after all,” said Dr. James Logan, who headed the research at the London School of Hygiene and Tropical Medicine. “Every time we identify a new part of how the malaria mosquito interacts with us, we're one step closer to controlling it better.” The sock findings were published last month in the journal, PLoS One. Malaria is estimated to kill more than 600,000 people every year, mostly children in Africa. Experts have long known that mosquitoes are drawn to human odors, but it was unclear if being infected with malaria made them even more attracted to us. Infected mosquitoes are believed to make up about 1 percent of the mosquito population. Using traps that only target malaria mosquitoes could result in fewer mosquitoes becoming resistant to the insecticides used to kill them. And it would likely be difficult for the insects to evade traps based on their sense of smell, scientists say. “The only way mosquitoes could (develop resistance) is if they were less attracted to human odors,” said Andrew Read, a professor of biology and entomology at the University of Pennsylvania, who was not part of Logan's research. “And if they did that and started feeding on something else - like cows - that would be fine.” Read said the same strategy might also work to target insects that carry other diseases such as dengue and Japanese encephalitis. In a related study, Logan and colleagues also sealed human volunteers into a foil bag to collect their body odor as they grew hot and sweaty. The odors were then piped into a tube next door, alongside another tube untainted by human odor. Afterwards, mosquitoes were released and had the option of flying into either tube. The insects buzzed in droves into the smelly tube. Logan said the next step is to identify the chemicals in human foot odor so that it can be made synthetically for mosquito traps. But given mosquitoes' highly developed sense of smell, getting that formula right will be challenging. Some smelly cheeses have the same odor as feet, Logan noted. “But mosquitoes aren't attracted to cheese because they've evolved to know the difference,” he said. “You have to get the mixture, ratios and concentrations of those chemicals exactly right otherwise the mosquito won't think it's a human.” Scientists said it's crucial to understand the subtleties of mosquito behavior. Other studies have shown mosquitoes don't become attracted to humans for about two weeks - the time it takes for the malaria parasites to become infectious for humans. “At the moment, we only have these glimpses of how parasites are manipulating the mosquitoes,” said George Christophides, chair of infectious disease and immunity at Imperial College London. “We need to exploit that information to help us control malaria.”source : http://www.foxnews.com/health/2013/06/04/stench-human-feet-may-lead-to-better-malaria-traps/
IM is an inheritied disorder that develops in infancy or even in utero and tumors continue to present throughout life. The tumors do not metastasize, but can grow large enough to invade the tissue surrounding them causing physical limitations, disfiguration, bone destruction, intestitinal obstruction, and even death. …
