Anti-herpes treatment reduces HIV levels in women infected with both viruses

...alth and clinical practice, as HSV-2 control could become a new form of HIV prevention targeting HIV-infected individuals, as well as providing clinical benefits. Importantly, an HSV vaccine that would either prevent HSV infection or diminish the clinical and sub-clinical manifestations of HSV with a simila...

Moonlighting enzyme linked to neurodegenerative disease

...eventually the symptoms progress and most patients become wheelchair-bound and succumb to heart failure later in life. There is no cure at this time, but Mayo Clinic researchers have identified mutations in an enzyme that may contribute to the disease. "Children and teens want to be on top of the world and...

Targeting tumors the natural way

...cells and tumor vasculature in large numbers, have become important targets in cancer research. In contrast, an established tumor-homing agent linked to the cell toxin doxorubicin destroyed cells even when they expressed very little integrin, indicating this strategy has the potential to kill cancerous a...

Liposuctioned fat stem cells to repair bodies

...ay it is impossible to re-programme adult cells to become nerve or liver cells, for example, without using e...r epigenetic marks. Cells can’t be pushed along to become a different cell type unless they start out with the right set of [epigenetic] conditions." It is...

Linheng Li Lab documents the development of cancer stem cells

...w publication that clarifies how normal stem cells become cancer stem cells and how cancer stem cells can cause the formation of tumors. The paper, "PTEN-deficient intestinal stem cells initiate intestinal polyposis" was posted to the Nature Genetics Web site on January 21. The theory that cancer stem...

CSHL research ties harmless viruses to cancer

...The researchers found that some of these cells can become cancerous. The model that the researchers propose suggests that the best hope for controlling cancer is its prevention. If viruses can cause CIN, identifying and inactivating these viruses would help to decrease the incidence of the disease. This...

Multiple malaria infection inhibits spread of parasite

...udied how people not previously exposed to malaria become infected or immune. Migrants in the province of Papua in Indonesia, who had not previously been exposed to malaria were investigated for this purpose. Malaria is highly prevalent in Papua. After just one to four malaria infections the immunity agains...

A revolution in the monitoring of unborn babies

... the placenta is unhealthy and hence the fetus may become compromised due to lack of oxygen.? In England during 2004 and 2005 17 per cent of inpatient cases for women in NHS hospitals were due to complications of pregnancy or childbirth. By helping to detect potential problems with unborn babies early an...

Circumcision: A proven strategy to prevent HIV

...said Bailey. "We do know that some circumcised men become infected with HIV. But we did find that the circumcised men in our study did not increase their risk behaviors after circumcision. In fact, all men in the trial increased their condom use and reduced their number of sexual partners." The authors c...

Reactivated gene shrinks tumors

...utation or deletion, cells are much more likely to become cancerous, because they will divide uncontrollably even when DNA is damaged. In this study, the researchers used engineered mice that had the gene for p53 turned off. But, they also included a genetic "switch" that allowed the researchers to turn ...

Anti-fungal drug stops blood vessel growth

...cholesterol, causing these primitive life forms to become fragile and break apart. It turns out that itraconazole can block the same enzyme in blood vessels, but the researchers aren’t positive if that’s the reason blood vessels stop growing, because related antifungal drugs had much lower inhibitory effect...

Genomics throws species definition in question for microbes

The report contains an in-depth review of the myriad issues and conflicts involved in the classification of micro...

Fruit fly gene research may shed light on human disease processes

...ate students have been researching how fly embryos become male or female, a process that occurs over a 30-minute period early in their development and which is similar to the differentiation process for different types of cells, mirroring, for example, the way a liver cell becomes different from a blood cel...

Cancer scientists create 'human' leukemia process to map how disease begins, progresses

The method we developed opens the pathway generally to understanding the process of how cancer begins." The scien...
