#Researcher finds potential new use for old drugsa class of drugs used to treat parasitic infections such as malaria may also be useful in treating cancers
Researchers discovered that simple modifications to the drug furamidine have a major impact on its ability to affect specific human proteins involved in the on-off switches of certain genes.
The proteins--known as transcription factors--regulate the expression of genes in a highly coordinated and intricate manner making them attractive targets for therapeutic drugs
But it has proven difficult to design drugs to affect them Poon said. For this reason they have been called undruggable he said.
Recently however scientists have been making headway in targeting these transcription factors with drugs and now our results suggest this class of drugs can be a useful addition to the arsenal.
Furamidine belongs to a family of drugs known as heterocyclic dications. The drug has a long history of use in serious parasitic diseases such as malaria African sleeping sickness and PCP a common infection in HIV/AIDS.
There is tremendous knowledge and experience with using furamidine and related drugs in humans so these drugs have an important advantage over other classes of drugs that are relatively behind in clinical experience Poon said.
Poon collaborated with researchers at Georgia State university. The team found that derivatives of furamidine can target a specific transcription factor known as PU. 1. Their findings were published in Nucleic acids Research journal.
PU. 1 is a major factor in development and function of the human immune system and it plays important roles in diseases such as some leukemias multiple sclerosis and diabetes.
The challenge now is to fine-tune this class of drugs to make them as specific as possible to other ETS-family transcription factors as well.

Tor reportedly has been used to aid in the selling of illegal drugs and in the proliferation of child pornography among other crimes.
Because many fungal pathogens develop resistance to prolonged treatment with antifungal drugs it is desirable to find alternatives for their control in medical agricultural and those applications in which the fungi cause damage.
In clinics pathogenic fungi resistant to antifungal drugs are a major cause of mortality in patients.
Many substances found in food have the potential to prevent Mets thus reducing the need for medication and medical intervention.
And you need to know the gene's function before you can start working on drugs or therapy.
#New drug to help common bowel diseasean international team led by University of Adelaide researchers has identified the mechanism of pain relief of a new drug for treating Irritable bowel syndrome with Constipation (IBS-C) based on nonclinical studies
Published in the journal Gastroenterology the study describes the pain mechanism of action for Linaclotide a recently approved drug for the treatment of chronic abdominal pain and constipation in adult IBS-C patients.
The drug is effective in relieving abdominal pain associated with IBS-C and is already available and registered for use by IBS-C patients in the USA and Europe.
IBS-C patients given the drug orally showed significant improvement in abdominal pain over those given placebo during a 26-week trial.

#Parasitic worm genome uncovers potential drug targetsresearchers have identified five enzymes that are essential to the survival of a parasitic worm that infects livestock worldwide
Two of these proteins are already being studied as potential drug targets against other pathogens. The team sequenced the genome of Haemonchus contortus
and will also reveal further potential drug and vaccine targets.##oeour reference genome allows researchers to understand how H. contortus
and other worms of this type acquire resistance to a wide range of anthelmintics#the drugs used to treat worm infections#says Dr James Cotton senior author from the Wellcome Trust Sanger Institute.#
#oeseeing a common theme of drug resistance in this well-characterised worm is extremely important because both people and animals are reliant on so few treatments against parasitic worms.#
#The team sequenced the genome of a strain of H contortus that was susceptible to all major classes of drugs against parasitic worms.
By comparing this sequence with that of worms that have acquired drug resistance the researchers expect to reveal a wealth of information about how
Getting to grips with genomes such as that of H. contortus is our best option to tackle the issue of drug resistance
and develop new drugs against parasitic worms to address this issue.##To generate a rich source of potential vaccine
and drug target candidates the team identified a set of genes that are more active in certain stages of the parasite life cycle and within the parasite s gut.
Two of these enzymes are already being studies as potential drug targets; one against Mycobacterium tuberculosis and another against another type of worm.
The researchers also described the full gene repertoires for known drug target families. This gives a comprehensive understanding of how several important treatments work against worms
#oerevealing new drug targets against H. contortus could provide much-needed new treatment opportunities against parasitic worms in both animals and humans.

and efficacy of administered annual antifilarial drugs over five years to residents of five villages in Papua new guinea.
The team demonstrated that the mass drug strategy nearly eliminated the parasite from humans but did not stop its transmission by mosquitoes.
The success of a strategy utilizing medication requires at least 80 percent of the population to receive treatment annually for at least five years.
Ten years after villagers took their last medication round they received free bed nets as part of Papua new guinea's national malaria control effort.
We should not rely solely on mass drug administration to eliminate lymphatic filariasis. By combining the existing strategy with vector control we are more likely to reach elimination thresholds said Lisa J. Reimer Phd first author on the paper and a lecturer at the Liverpool School of Tropical Medicine.
The group also will test new drug combinations for mass treatment in nearby populations and evaluate the effects of broader bed net distribution in the country.
when we pre-treated cancer cells with apigenin for 24 hours then applied the chemotherapeutic drug gemcitabine for 36 hours said Elvira de Mejia a U of I professor of food chemistry and food toxicology.
and the chemotherapeutic drug simultaneously said Jodee Johnson a doctoral student in de Mejia's lab who has graduated
Even though the topic is still controversial our study indicated that taking antioxidant supplements on the same day as chemotherapeutic drugs may negate the effect of those drugs she said.
One of the ways that chemotherapeutic drugs kill cells is based on their pro-oxidant activity meaning that flavonoids
and chemotherapeutic drugs may compete with each other when they're introduced at the same time she explained. Pancreatic cancer is a very aggressive cancer
But scientists could design drugs that would achieve those concentrations de Mejia said. And prevention of this frightening disease is another story.
Her work also has highlighted how the tobacco industry has sponsored research to promote the self-medication hypothesis--that patients with psychiatric disorders need to smoke to function
Smoking also can interfere with treatment affecting the metabolism of some psychiatric medications Prochaska said.
For instance it increases the body's elimination of olanzepine a drug used for psychosis or psychotic depression by more than 90 percent and of Haldol a common schizophrenia drug by 44 percent.
because the tobacco smoke is reducing the sedating side effects of their psychiatric medications she said.

Only human strains of CC97 were able to resist the drug which indicates that the bacteria acquired resistance after they crossed over into humans presumably through exposure to antibiotics prescribed for treating human infections.
Any number of factors could create these differences making pigs--but not cattle--a source of a drug-resistant bacterium.
The research team developing the drug--led by scientists at the Nanomedicine Research center part of the Maxine Dunitz Neurosurgical Institute in the Department of Neurosurgery at Cedars-Sinai Medical center--conducted the study in laboratory mice with implanted human
Mice receiving the drug lived significantly longer than untreated counterparts and those receiving only certain components of the drug according to a recent article in the Journal of Controlled Release.
Unlike other drugs that target cancer cells from the outside often injuring normal cells as a side effect this therapy consists of multiple drugs chemically bonded to a nanoplatform that functions as a transport vehicle.
One commonly used drug Herceptin (trastuzumab) often is effective for a while but many tumors become resistant within the first year of treatment
and the drug can injure normal organs it contacts. But Herceptin is an antibody to the HER2 gene--it naturally seeks out this protein--so the research team used key parts of Herceptin to guide the nanodrug into HER2-positive cancer cells.

Cornell hospital clinicians worked to prepare for intravenous medication delivery. In the first such procedure ever done to treat a sick pig surgeon Jim Flanders who had performed similar procedures in smaller animals joined large-animal surgeon Susan Fubini to surgically implant a vascular access port.
They ran a catheter up a vein in Nemo's neck to a port behind his ear creating a route for delivering drugs where they would be most effective
and delivered the chemotherapeutic drugs. Although lymphoma has been documented in swine there aren't any documented cases of pigs being treated for it said Cornell hospital oncologist Cheryl Balkman.

#Poultry drug increases levels of toxic arsenic in chicken meatchickens likely raised with arsenic-based drugs result in chicken meat that has higher levels of inorganic arsenic a known carcinogen according to a new study
whether or not the poultry was raised with arsenical drugs. The findings provide evidence that arsenical use in chickens poses public health risks
and Drug Administration (FDA) the agency responsible for regulating animal drugs should ban arsenicals experts say.
and June 2011 when an arsenic-based drug then manufactured by Pfizer and known as roxarsone was readily available to poultry companies that wished to add it to their Feed in addition to inorganic arsenic the researchers were able to identify residual roxarsone in the meat they studied;
Arsenic-based drugs have been used in poultry production for decades. Arsenical drugs are approved to make poultry grow faster
and improve the pigmentation of the meat. The drugs are approved also to treat and prevent parasites in poultry.
In 2010 industry representatives estimated that 88 percent of the roughly nine billion chickens raised for human consumption in the U s. received roxarsone.
In July 2011 Pfizer voluntarily removed roxarsone from the U s. market but the company may sell the drug overseas
Pfizer still domestically markets the arsenical drug nitarsone which is chemically similar to roxarsone. Currently in the U s. there is no federal law prohibiting the sale or use of arsenic-based drugs in poultry feed.
In January Maryland became the first U s. state to ban the use of most arsenicals in chicken feed.
Hopefully this study will persuade FDA to ban the drug and permanently keep it off the market.
