and New zealand--by making female flies dependent upon a common antibiotic to survive. Dr. Max Scott professor of entomology at NC State and his research team genetically modified lines of female Australian sheep blowflies (Lucilia cuprina) so that they required doses of tetracycline in order to live.
Female blowflies that did not receive the antibiotic died in the late larval or pupal stages before reaching adulthood.
Several genetically modified lines lacking tetracycline showed 100 percent female deaths. Scott says that the gene construct responsible for lethality in antibiotic-free diets is female-specific Interestingly
and unexpectedly the genetically modified female larvae containing the tetracycline lethality genes also took on a crimson color due to overexpression of the linked red fluorescent protein marker gene.
This allows scientists to tell which larvae will be females and which will be males. Overexpression of the gene responsible for the reliance on tetracycline also seems to overexpress this marker gene Scott says.
Since the females will die when not provided tetracycline in their diets the males can be separated out in the larval stage.
This is essential for a male-only genetic control program to reduce blowfly populations Scott says as fertile males would pass the lethality construct on to female offspring
which would die in the absence of tetracycline. Male larval offspring however would still be dangerous to livestock.
In the study the researchers showed that the tetracycline gene construct also works in Drosophila the fruit fly lab rat of the insect world that is a distant cousin of the sheep blowfly.
This holds promise that the genetic system will function in the New world and Old world screwworm two major livestock pests that are close relatives of the sheep blowfly.

#Tomato pill improves function of blood vessels in patients with cardiovascular diseasea daily supplement of an extract found in tomatoes may improve the function of blood vessels in patients with cardiovascular disease according to new research from the University of Cambridge.
Dr Joseph Cheriyan consultant clinical pharmacologist & physician at Addenbrooke's Hospital and Associate Lecturer at the University of Cambridge says:
The researchers carried out a randomised double blind placebo controlled interventional trial investigating the effects of lycopene a gold standard method of measuring the function of blood vessels called forearm blood flow

which treatment was being provided. The patients with cardiovascular disease were all on statins (cholesterol-lowering drugs.
However despite this they still had impaired a relatively function of the endothelium--the inner lining of blood vessels--compared to healthy volunteers.
Lycopene improved the widening of the blood vessels by over a half (53%)compared to baseline in those taking the pill after correction for those who took the placebo;

Promising drug therapies for fatal lung disease foundresearchers in separate clinical trials found two drugs slow the progression of idiopathic pulmonary fibrosis a fatal lung disease
which there is currently no therapy approved by the Food and Drug Administration. Paul W. Noble MD chair of the Department of Medicine at Cedars-Sinai and director of the Women's Guild Lung Institute is the senior author of the multicenter study that found that the investigational drug pirfenidone

#Antimicrobial edible films inhibit pathogens in meatantimicrobial agents incorporated into edible films applied to foods to seal in flavor freshness
The results demonstrate that the bacterial pathogens were inhibited significantly by the use of the antimicrobial films said Catherine Cutter professor of food science.
She hopes that the research will lead to the application of edible antimicrobial films to meat and poultry either before packaging or more likely as part of the packaging process.
and the researchers determined the antimicrobial activity of these films against bacterial pathogens inoculated onto petri dishes.
and have them do double duty--releasing antimicrobials and imparting characteristics to protect and improve food we eat.
but effective way to deliver antimicrobial agents to meats Cutter explained because the bacteria-killing action is longer lasting.
The pullulan films adhere to the meat allowing the incorporated antimicrobials to slowly dissolve providing immediate and sustained kill of bacteria.
However the one thing I really want to be able to do in the next few years is to figure out a way to co-extrude antimicrobial edible films with the polyethylene
so we have the true oxygen barrier properties of the plastic with the antimicrobial properties of the edible film.
Knowing that edible films can release antimicrobials slowly over time and keep bacteria in meat at bay further research will be aimed at creating
what Cutter referred to as active packaging--polyethylene film with antimicrobial properties. Right now we have two different packaging materials that are not necessarily compatible leading to a two-step process.
I keep thinking there's a way to extrude edible antimicrobial film in one layer with polyethylene creating all-in-one packaging.

#Insects represent link for antibiotic resistance traitsthose pesky house flies buzzing around your home or invading your springtime picnic could be doing more harm to human health than you realize.
According to a recent study by Kansas State university published in the Applied and Environmental Microbiology journal insects carry antibiotic-resistant bacteria from one point to another including from food animal farms and wastewater treatment
and again we found house flies with multi-drug resistant bacteria. The house flies collected from the wastewater treatment plants likewise carried the same bacteria found in the waste itself he said.
House flies collected several miles from the wastewater treatment plants in surrounding urban areas had a lower prevalence of the antibiotic-resistant bacteria than those examined from the facilities themselves
The study led the researchers to conclude that insects primarily house flies can pick up antibiotic-resistant bacteria
They have great potential to move multi-drug resistant bacteria to urban areas. In addition Zurek's team showed that bacteria in the house fly digestive tract can exchange antibiotic resistance by horizontal gene transfer.
The resistant strains multiply in the fly and can be left behind on food by fly regurgitation or spitting and defecation.
Background on antibiotic resistanceantibiotics since their discovery 70 years ago have saved millions of lives Zurek said.
Unfortunately because of the intensive use of antibiotics in human medicine we pose high pressure on bacteria
and are selected by antibiotic treatments. Currently we have situations where people get infections they die from
because the antibiotics are not effective anymore. The bacteria that caused the infections are multi-drug resistant.
According to a 2013 report by the Centers for Disease Control and Prevention (http://www. cdc. gov/drugresistance/threat-report-2013) at least 2 million people become infected with antibiotic-resistant bacteria
and at least 23000 people die each year as a direct result of these infections in the United states. Currently two places where antibiotics are used most widely are hospitals
and food animal production facilities Zurek said. Antibiotics in food animal production are used not only to treat infections in animals
but also in helping animals grow. Antibiotics in low doses are added as feed additives primarily in poultry
and swine diets he said. The outcome is that the animals grow faster. At the same time if you use low doses of antibiotics extensively that poses selective pressure on bacteria in the digestive tract of these animals and results in antibiotic resistance.
Humans experiencing more problems with antibiotic resistance could be due to many potential reasons Zurek said including overuse of antibiotics in human medicine and human connection to antibiotic use in food animals.
There are likely many other potential environmental connections as well so it's hard to pinpoint specific infections
and where the antibiotic resistance originated. In addition to the insects Zurek and his research team have showed also that wild birds such as ravens
and crows carry multi-drug antibiotic-resistant bacteria. Wild birds can pick up the antibiotic resistant bacteria from fields where animal manure was used as a fertilizer he said.
We still don't know how significant these birds are as carriers. We just know there are multiple venues where wildlife can acquire resistant strains and move them around in the environment.
and Drug Administration last December released its first request to antibiotic manufacturers to voluntarily remove antibiotics from the list for animal growth promoters.
The plan is to phase out antibiotics as a feed additive for growth promotion in United states in the next three years.
The European union (EU) took a precautionary step in 2006 to combat human antibiotic resistance. All EU countries banned antibiotic use as growth promoters in food animals.
Lowering the use of antibiotics in animal industry will be another step to lower prevalence of antibiotic resistant bacteria in the environment
and in human infections Zurek said but because antibiotic resistance in human infections is such a serious global health problem that has led to higher patient mortality rates prolonged hospitalization
and increased healthcare costs it needs to be tackled from many angles. Clearly pest management and trying to minimize the pest populations on farms
They can carry antibiotic resistant bacteria so they should be taken seriously as a vector. Story Source:
