Possible 'superbug' status for STI

The rise of multidrug resistance in gonorrhoea-causing bacteria is threatening to make this sexually-transmitted infection extremely difficult to treat.

Keeping skeletal stem cells ‘young'

Scientists showed in mice that a molecule called Notch, which is well known for the influence it wields on stem cells that form the blood and the nervous system, is a key factor in the development of mesenchymal stem cells.

Beta-blockers help reduce metastasis

A team of scientists found that the group of patients treated with beta-blockers showed a significant reduction in metastasis and better survival.

Molecular prosthesis against gout

Researchers have devised a new method for preventing and permanently eradicating the cause of gout. It involves implanting a biological network that regulates the uric acid levels autonomously.

New understanding of protein's role in brain

A team of researchers has discovered that brains in mammals modify a particular protein in a unique way, which alters the protein's normal function.

Proteins may point to alcohol use test

Measuring a set of protein changes in the blood linked to alcohol use may potentially lead to a more accurate diagnostic test than those currently available, according to recent research.

Transcription factors may dictate individual differences

Researchers are only beginning to understand how individual variation in gene regulation can have a lasting impact on one's health and susceptibility to certain diseases.

Acne drug prevents HIV in lab

Scientists have found that a safe and inexpensive antibiotic in use since the 1970s for treating acne effectively targets infected immune cells in which HIV lies dormant and prevents them from reactivating and replicating.

Growth factor promotes stem cell growth

Scientists have identified a new growth factor that stimulates the expansion and regeneration of hematopoietic stem cells in culture and in laboratory animals.

New ways to TB

Researchers have found two novel ways of killing the bacteria that cause tuberculosis, a disease responsible for an estimated two million deaths each year.

Blocking cancer in its path

Researchers have discovered that a key cellular defect that disturbs the production of proteins in human cells can lead to cancer susceptibility.

Brain tumour growth switch discovered

A recent study shows that a molecule called miR-451 coordinates the grow-or-go behaviour of tumour cells, and that the change is accompanied by slower cell proliferation and an increase in cell migration.

Vitamin D and calcium interplay explored

A recent study underscores the importance of vitamin D and its ability to help the body utilise calcium and may explain why increasing calcium alone isn't always successful in dealing with this problem.

Turning molecules into super protein killers

Using a novel light activation technique, scientists have been able to turn molecules with only a modest ability to fight specific proteins into virtual protein destroyers.

Understanding of how mosquitoes find a host

The potentially deadly yellow-fever-transmitting Aedes aegypti mosquito detects the specific chemical structure of a compound called octenol...

Disarming hemorrhagic fever viruses

Researchers have discovered exactly how one type of New World hemorrhagic fever virus latches onto and infects human cells, offering a much-needed lead toward new treatments.

Bone marrow can harbour HIV-infected cells

Scientists have identified a new reservoir for hidden HIV-infected cells that can serve as a factory for new infections.

Novel approach to prostate cancer treatment

Researchers in Canada have detected a novel oncolytic viral therapy against prostate cancer with use of a virus called the reovirus, according to study results.

Periodontal pathogens enhance HIV-1

Although oral co-infections are highly prevalent in HIV-1 patients and appear to positively correlate with viral load levels, the potential for oral bacteria to induce HIV-1 reactivation in latently infected cells has received little...

Vitamin D crucial to activating immune defences

Scientists have discovered that Vitamin D is crucial to activating our immune defences and that without sufficient intake of the vitamin, T cells - will not be able to fight off serious infections in the body.
