Discovery of natural compounds that could slow blood vessel growth
sea-maid submitted, created time 1 day 15 hours (esciencenews.com)
Using a whole-genome approach, researchers have found more than one hundred human protein compounds that can slow blood vessel growth. This could lead to treatments against diseases that depend on the growth of new blood vessels, including cancer, macular degeneration and rheumatoid arthritis. 
Monoclonal antibodies come of age, and passive immunity treatments come around
sea-maid submitted, created time 1 week 5 days (www.nature.com)
Monoclonal antibodies, antibodies that are made from a single cell line and that bind to a specific part of a specific antigen, are much more precise than polyclonal antibodies, but they are more expensive and difficult to make. However, a new system of isolating antibodies from human patients has been used to create a library of immune proteins. So far, things seem to be going well. This could open the door for what researchers are calling "passive immunity
Maternal flu shots protect newborns: U.S. study

Flu shots given to pregnant women a month or more before delivery will prevent most cases of influenza during the first six months of their babies' lives, researchers said.
Link Between Vitamin D And Multiple Sclerosis

Vitamin D, the principal regulator of calcium in the body, may prevent the production of malignant cells such as breast and prostate cancer cells and protect against specific autoimmune disorders including multiple sclerosis (MS) according to an article by Sylvia Christakos, PhD, of the UMDNJ-New Jersey Medical School.
In the article, Christakos reports that research shows that the incidence of MS decreases as the amount of vitamin D available to the body increases, either through sunlight exposure or diet
Immunosuppressive Drug Merits Fungal Warning

The Food and Drug Administration has asked the manufacturers of Humira, Cimzia, Enbrel, and Remicade—which belong to a class of medications known as tumor necrosis factor alpha blockers (TNF-alpha blockers)—to strengthen the warning for risk of fungal infection.
Study Dispels Link Between Autism and Measles Vaccine

Hoping to dispel long-running concerns that autism is linked to the measles-mumps-rubella vaccine (MMR), researchers now say a new study shows the childhood vaccine does not raise that risk.
New nano device detects immune system cell signaling
sea-maid submitted, created time 1 month 2 days (esciencenews.com)
Scientists have detected previously unnoticed chemical signals that individual cells use to communicate with each other over short distances. Minding the communiques of individual cells might not be so important for studying the heart or bones, but it is absolutely crucial to studying the immune system.
A New View of Why Cholera Won't Go Away

Cholera first infected humans in the early 19th century in Bengal, a region that straddles what is now the border between Bangladesh and India, and the bacterial disease still sweeps through the area regularly. After sifting through historical records of cholera deaths in Bengal, a team of scientists in the United States and Europe proposes a new explanation for these repeated outbreaks, suggesting that immunity to cholera wanes more rapidly than thought and that many more people than believed become infected without exhibiting symptoms
Black Americans have higher rates of HIV than some African countries
Darkfrog submitted, created time 2 months 5 days (www.nytimes.com)
According to the Black AIDS Institute, the United States may have a lower incidence of HIV than other countries overall, but U.S. blacks, considered alone, aren't so lucky. With 600,000 African-Americans living with HIV and 30,000 new infections each year, if American blacks were a country on their own, they would rank sixteenth worldwide. What's more, infected blacks are much more likely to die than infected whites, after adjusting for age (the article does not say that it adjusted for socioeconomic status)
Parasitic worms may boost African HIV rates.

ONE of the biggest mysteries of HIV is why the virus spreads so readily via heterosexual sex in Africa but not elsewhere. A study in monkeys suggests parasitic worms may be to blame.
Parasitic worms may help fuel AIDS epidemic: study

People infected with parasitic worms may be much more susceptible to the AIDS virus, according to a study published on Tuesday that may help explain why HIV has hit sub-Saharan Africa particularly hard.
The study involving monkeys demonstrated how a type of parasitic worm that causes schistosomiasis, which affects 200 million people globally, may make HIV infection more likely.
Much lower amounts of the AIDS virus--seventeen times lower--were needed to cause infection in monkeys who had the parasitic worms than in the parasite-free monkeys, the researchers said
Genetically engineered tobacco plants used to grow anti-lymphoma vaccine
Darkfrog submitted, created time 2 months 1 week (www.sciam.com)
Reports in the Proceedings of the National Academy of Sciences report that an experimental vaccines has triggered the immune systems of eleven (out of sixteen) patients to attack their tumors. The patients are afflicted with what is called follicular B-cell lymphoma. Dangerous side effects? None.
The interesting part? The vaccine was grown courtesy of some genetically engineered tobacco plants.
Of course, all of the patients were also receiving chemotherapy at the time, so it may be difficult to tell which results may be attributed to the vaccine itself

Developing a way to reliably produce hematopoietic stem cells is a bloody tough problem. Unlike most tissues, cells of the hematopoietic system emerge from several embryonic sites and then circulate through the body. This mobility has perplexed researchers, who hope that mimicking the in vivo environment will help them culture these stem cells. Now, two British research teams report in Cell Stem Cell their complementary techniques for isolating these cells. These methods could form the lifeblood of creating easier alternatives to bone marrow transplantation.

It seems like common sense: Reduce insect populations, and insect-borne diseases will decline as well. But a new study of dengue, a viral disease transmitted by Aedes mosquitoes, suggests the opposite. Controlling mosquitoes may result in more cases of dengue hemorrhagic fever (DHF), a rare and sometimes fatal disease caused by the virus.
Researchers think that tens of millions of people in the tropics become infected with the dengue virus each year. The pathogen can spur dengue fever, which is marked by agonizing muscle and joint pains but is rarely fatal
Government HIV vaccine doesn't make it out the gate
Darkfrog submitted, created time 2 months 2 weeks (www.nytimes.com)
Plans for a large-scale clinical trial of an HIV vaccine developed by the U.S. government were cancelled this week. The researchers fear jumping into human trials too soon, without knowing more about how their vaccine will affect the volunteers. Here is a quote:
"The trial canceled Thursday was supposed to have started enrolling 8,500 volunteers last October to receive the PAVE [Partnership for AIDS Vaccine Evaluation] vaccine, developed by the infectious diseases agency
