No está claro cuán grande es el papel de los antibióticos https://antibioticos-wiki.es en las relaciones competitivas entre los microorganismos en condiciones naturales. Zelman Waxman creía que este papel era mínimo, los antibióticos no se forman sino en culturas limpias en entornos ricos. Posteriormente, sin embargo, se descubrió que en muchos productos, la actividad de síntesis de antibióticos aumenta en presencia de otros tipos o productos específicos de su metabolismo.

SUNSHINE HEARTSunshine Heart says that most of the 20-patients in its pilot trial of the C-Pulse aorta cuffpump improved heart failure categories.
Sunshine Heart did not provide detailed results, but said that one patient died in aninfection-related operation and two patients improved to the point that they weredisconnected permanently from the heart pump system.
The summarized data was published by the Ohio State University Medical Center and thecompany said the detailed results would be presented at the TranscatheterCardiovascular Therapeutics meeting in San Francisco on November 8, 2011.
Ohio State University Medical Center said that 20 patients, eight women and 12 men withan average age of 56, were enrolled in the trial, of which 18 were classified with New YorkHeart Association (NYHA) class III heart failure and two were class IV, the most severeforms of heart failure.
All patients had cardiac resynchronization therapy, implantable cardiac defibrillators orcombination devices implanted, the Medical Center said.
The Medical Centre said three patients were successfully bridged to transplant with onepatient being supported for 22 months, the longest of any patient participating in the trial.
The Medical Centre said that all but one patient either improved or maintained NYHAheart failure classification.
Sunshine Heart chief executive officer Dave Rosa told Biotech Daily that the results werestill being finalized, with some detail being held back for the San Francisco conference.
“The majority of patients improved, rather than maintained classification, and this is acondition in which patients normally deteriorate,” Mr Rosa said.
Mr Rosa said that two patients improved to the point that they did not require the device,due to the absence of heart failure symptoms, and along with the overall reduction inpatient medication, were positive indicators for the device.
Mr Rosa said that one patient was disconnected after the six month follow-up and thesecond patient after 11 months on therapy.
The Medical Centre said that overall, other improvements were realized as measured byquality of life scores, six-minute walk times, ejection fractions, or the heart’s pumpingability, and reductions in medications.
Mr Rosa said that the patient who died had a non-device-related infection and diedfollowing surgery to treat the infection.
Mr Rosa said there were a number of contributing factors in the death from an aorticdisruption, as a result of a re-sternotomy surgery to treat the procedure-related infection.
The Medical Centre said no neurologic events or heart attacks were reported, while sixsuperficial exit site infections were successfully treated with antibiotics.
The Medical Centre said there was one instance of post-operative, non-device relatedbleeding.
The Medical Centre said that the results warranted a larger pivotal trial.
The Medical Centre’s director of cardiovascular medicine and co-lead principalinvestigator Dr William Abraham said the trial results to date “show positive trends ofefficacy with a strong safety profile as compared to later stage mechanical supportdevices”.
“We believe further investigation is needed as hundreds of thousands of heart failurepatients in this country remain substantially symptomatic despite currently availabletreatments,” Dr Abraham said.
The C-Pulse aorta cuff uses an electrocardiogram-sensing wire to inflate and deflate thecuff to assist the heart, reducing aortic pressure and the heart’s workload.
Sunshine Heart was unchanged at 4.7 cents.
AUSBIOTECH, FEDERAL GOVERNMENTAusbiotech has welcomed a Senate report recommending that the Patent Amendment(Human Genes & Biological Materials) Bill 2010, should not be passed.
Ausbiotech said the Senate Legal and Constitutional Committee Inquiry into the Bill wastabled in the Senate last night.
A Senate officer told Biotech Daily that the Bill was a private members bill sponsored byLiberal Senators Helen Coonan and Bill Heffernan, Greens Senator Rachel Siewert andindependent Senator Nick Xenophon.
The Senate officer said the only opportunities for the Bill to have its Second Reading wereon Thursday mornings when the Senate was sitting and it was unlikely the Bill would beread this year.
The Government dominates the Senate Legal and Constitutional Committee, but theGreens and Coalition could command a majority in the Senate to pass the Bill.
Ausbiotech chief executive officer Dr Anna Lavelle welcomed the Committee’s finding.
“This is the right outcome for patients, researchers and for innovation in this country. I nowcall on the Senate to abandon the Bill, as recommended,” Dr Lavelle said.
Ausbiotech said there had been five Australian inquiries in recent years into patentablesubject matter and each has consistently recommended that excluding specific subjectmatter from patentability was not the right option.
Ausbiotech said the proposed Bill “fails completely to address any of the valid concernsraised by the community about gene patents and should be rejected”.
“The Bill does not serve the interests of patients, researchers or industry and, in fact, theBill threatens the very foundations of scientific research and development of biologicaltherapies and other technologies which are built on patents,” Dr Lavelle said.
The Australian Greens told Biotech Daily they did “not believe it appropriate forpharmaceutical and biotechnology companies to be able to own the intellectual propertyrights and enjoy exclusive use of human genes”.
“Isolated genetic material should be regarded as a discovery, not as an invention,” theGreens said.
“We are particularly concerned by the prospect that such patents could see exorbitantfees charged for medical tests and treatments for many diseases, including cancer,” theGreens said.
MAYNE PHARMA GROUPMayne Pharma says it has been granted a preliminary injunction against Mylan Inc andaffiliate Mylan Pharmaceuticals preventing the launch of a generic Doryx 150mg.
Mayne said the US District Court of New Jersey granted the preliminary injunctionpreventing the launch before the Court rendered a decision in the on-going litigationrelating to US Patent No 6,958,161 covering the tetracycline-class oral antibiotic Doryxproducts, and no trial date had been set.
The company said that in granting the motion, the District Court found that Mayne Pharmaand its US marketing and distribution partner Warner Chilcott demonstrated a reasonablelikelihood of success on the merits of their claim that the ‘161 Patent was valid andinfringed by Mylan’s 150mg generic Doryx product.
Mayne said it manufactured and supplied Doryx to Warner Chilcott in the US under alicence agreement and owned the ‘161 Patent.
The company said the Doryx 150mg product was more than 95 percent of the Doryxfranchise in the US based on total prescriptions.
Mayne fell 2.5 cents or 6.3 percent to 37 cents.
