Protecting human subjects focus of national FDA conference at UH

Sunday, November 29th, 2009

Streamlining, increasing medical device approvals end of two-day event -

New medical devices be enduring to be tested on human subjects, but protecting the rights of those subjects can just now considerable
challenges for researchers. A popular conference loyal to exploring the FDA critical pathway for approval of up to date medical
products while protecting human subjects, co-sponsored by the Scoff and Drug Administration and the University of Houston,
will be held at UH April 21-22.

One of only three annual conferences sponsored by the U.S. Worry of Health and Human Services’ Office of Kind Fact-finding
Protections (OHRP), UH is hosting “The Depreciative Path to New Medical Products: The Challenges in Protecting Human Subjects.”
The two days of presentations, panels and breakout sessions intention be held at the Hilton UH Hotel and Conference Center.

“While the increased potential is tremendous for green medicines, biologicals and genomic-based treatments and devices that
bar and cure diseases, fewer untrained medical devices are reaching the marketplace,” said Isaac D. Montoya, clinical professor
in the UH College of Dispensary. “The shortest distance between two points is a sort out stripe; however, the stroke that leads to
developing unusual medical devices is rarely short or straight. This colloquy will review options and approaches for congregation
this brave while protecting mortal subjects.”

The “critical path” of medical merchandise development includes the development and essential steps that resolve whether and how
right away a medical discovery becomes a predictable device quest of patient use. With a number of challenges and issues concerning the
sanctuary of human subjects, this “critical path” will be thoroughly examined. Participants resolution be given applicable
information give conducting biomedical research, as wholly as being provided an update on the regulations and presented with
an overview of the challenges, issues and potential solutions facing regime and the reserved sector in conducting
federally funded research involving understanding subjects.

The seminar is designed to benefit chairperson investigators, experiment with staff and coordinators, those involved in
institutional evaluate boards (IRBs), institutional officials, pharmaceutical into personnel and medical personnel with an
property in human subjects patronage, as well as graduate and undergraduate students. In completing the two-day program,
participants can presume to demonstrate a better overall understanding of the Code of Federal Regulations from the Place by reason of
Protection from Research Risks that govern enquiry funded by Title 45 Part 46 on clientele good fortune and the protection of human
subjects.

Additional benefits categorize the ability to apply upright principles and regulations to research involving human subjects,
recognize opportunities and solutions to compliance issues in person research studies conducted by academia and the unsocial
sector, apply examples and definitions provided to complex and problematical research issues, and demonstrate instruction of
superintendence initiatives such as the “critical path” of medical merchandise expansion and marketing. Broadsheet sessions will begin
at 8 a.m. each day that pose as student slave away in the court.

Montoya, the conference chairman and coordinator, longing add Jay Gogue, chancellor of the UH System and president of UH,
who will-power officially open the conference at 9 a.m., April 21. To kick off day one, OHRP Director Bernard A. Schwetz, D.V.M,
will deliver the first keynote address - “Aspects of the Human Subjects Enterprise.” Following, whim be David A. Lepay, M.D.,
elder adviser object of clinical study at the FDA, who will provide insight to FDA regulations involving the protection of human
subjects in clinical trials and the organization’s keeping role.

Offering a number of panel discussions that provide a wide range of perspectives from the federal superintendence, concealed
earnestness and academia, many distinguished figures will be in attendance, as far as giving presentations on topics such as the use
of unapproved devices, bioterrorism and latitude fact-finding. Included in this august slope is Charles F. Sawin, the chief NASA
scientist serving as chair of the Committee for Protection of Human Subjects and chair of the Lenient Research Multilateral
Review Board at NASA’s Johnson Array Center (JSC). As a complete figure in the IRBs of JSC and the International Elbow-room Station,
Sawin will deliberate over issues relating to conducting inquire into in latitude that involves human subjects. In addition, CEO’s from
MicroMed Technology, Pharma Frontiers and BioHouston also will be on hand to review issues experienced facade the private
sector.

Additional topics will cover FDA monitoring and sanctions, new issues that are arising with the developing bionanotechnology
field and bioterrorism issues faced by the U.S. Office of Homeland Safety.

“While UH is the landlady, the forum is very much a community feat,” Montoya said. “Among an impressive array of speakers
will be top Texas Medical Center representatives and genius from The University of Texas Haleness Branch Center, Baylor
College of Medicine and M.D. Anderson Cancer Center. We’ve also had pre-med students from the local chapter of the American
Medical
Student Linkage sign on as volunteers. I’m positively gratified with the level of involvement and the unity exhibited
by so many in this noteworthy result.”

Mechanics of atherosclerosis

Saturday, November 28th, 2009

Atherosclerotic narrowing and hardening of coronary arteries typically appear first at boat branches, and a study in the October issue of Cellular Signalling reports that the personification of dead stretching found at those branches activates a cellular protein known to damage cells.

The report is the first to link mechanical forces with structural and biochemical changes in blood vessel cells that could explain why atherosclerotic lesions form preferentially at branches of coronary arteries.


The findings, which are currently available online at the journal’s Website, were reported by a team of scientists at the University of California, San Diego as part of an ongoing effort to understand how mechanical forces affect the health of cells that line arteries.


The cellular protein in question is called JNK, which is short for c-jun N-terminal kinase. The protein is a key barometer of outside stresses on a variety of cell types. Researchers are examining the role of JNK in many diseases because it regulates the expression of genes involved in programmed cell death, tumor genesis, and other stress responses.


Atherosclerosis, the collection of deposits such as cholesterol along artery walls, accounts for nearly 75 percent of deaths from cardiovascular disease. Most drugs to treat atherosclerosis influence the levels of cholesterol and other lipids in the blood, but the UCSD researchers suspect that understanding the role of mechanical forces acting on blood vessel cells may help to design better approaches to treatment.


“We’ve known for decades that atherosclerotic lesions develop preferentially at vessel branches rather than along unbranched vessels, but we’ve not been able to identify the biochemical events that trigger formation of the lesions,” said Chien, director of the Whitaker Institute of Biomedical Engineering at UCSD. “We now have identified a possible smoking gun: activation of JNK, which is dependent on the directionality of blood vessel stretching.”


Chien, research scientist Shunichi Usami, and post-doctoral fellow Roland Kaunas, now an assistant professor of biomedical engineering at Texas A&M University, isolated endothelial cells from the bovine aorta and grew them in culture flasks. They seeded the cells onto silicone rubber membranes that had been coated with a protein that allowed the cells to attach the way they do to underlying blood vessel tissue in the body. They then stretched endothelial cells 10 percent of their length 60 times per minute to simulate the rhythmic flexing of an artery in response to heart beats.


Cells that were stretched back and forth along one axis exhibited a healthy response: the level of JNK rose and quickly returned to basal levels as the cells also produced well-aligned intracellular actin fibers that were aligned perpendicular to the axis of stretch. When the researchers stretched cells in two directions simultaneously, they noted an unhealthy response: actin fibers oriented randomly and JNK concentrations rose to higher levels and remain elevated.


“We’re continually amazed at how quickly these cells can reorient these stress fibers when we change the direction of stretch,” said Chien. “At the same time, the actin cytoskeleton of endothelial cells is somehow playing a key role in activating and deactivating JNK.”


The tubular geometry of the straight part of arteries ensures that the cyclical rise and fall of blood pressure results in uniaxial stretch of arteries. However, the more complex geometry of artery branches promotes an unhealthy stretching of the blood vessel along more than one axis.


A second mechanical force, the so-called shear force of blood flowing through vessels, also influences the orientation of stress fibers in endothelial cells. A laminar flow of blood prompts stress fibers to orient in the healthy direction, while disturbed and low blood flows caused stress fibers to form in an unhealthy, random orientation. Chien’s group is now working to understand how both stretching and shear forces influence JNK activation.


“We still need to limit the amount of cholesterol in our diet, especially the low-density lipoprotein, or bad cholesterol,” said Chien. “But our new understanding of how mechanical forces affect JNK will eventually help us gain better understanding of the mechanism underlying the focal localization of atherosclerotic lesions and design better approaches to treat this important disease state.”

Swine Flu Continues To Spread, Health Officials Say Simple Steps Can Prevent It

Thursday, November 26th, 2009

Swine flu has been prominent in countries across the incredible, including the Partnership States. As of April 29, there were approximately 90 cases confirmed in the U.S., while in Mexico (where the cases are thought to have originated), reports of anywhere from generally 50 to round 150 deaths are thought to be quickly related to the flu.

“There is certainly a cause for appertain to,” said Wendy Macey, PA-C. Macey is the stream evil-president of the Association of Family Practice Physician Assistants. “The outcome of this condition is unheard-of, but as medical professionals, we are hopeful that people want adopt some healthier practices as a end result.”

These healthier practices include thorough hand washing. “People always whine about how cliché hand washing is!” Macey exclaimed. “But it’s a cliché because it’s factual.” Fitted the conquer results, Macey advises to get the soda water as hot as you can stand it, and carry up for the duration of 30 seconds.

“The other best clearance to intercept the spread of illness is to stay home if you are vicious,” Macey stated. “Don’t go to vocation. Don’t send your children to school. It’s better to miss a couple of days of accommodate wheedle then to infect your entire office.” While admitting that missing responsibility is usually easier said than done, Macey pointed out that people typically retake much faster when taking a couple of days to fully take it easy.

“Patients will sometimes complain of colds that linger on and on,” Macey said. “I believe that if they took a join of days off at the dawning, they would have found that they would have recovered much more quickly.”

Initially developing in Mexico, swine flu has fast spread all the way through the era, with approximately 50 cases in the Pooled States as of April 28. However, it has only been merciless to those in Mexico - all other cases procure been reported as clement, with most the patients recovering spontaneously. “The World Salubrity System has informed citizens to be sensible that a pandemic is quite practical,” Macey warned. “But I think we’re all cautiously optimistic that any impact of the swine flu will be minimal throughout the over the moon marvellous.”
