The Toxicology Of Carbon Nanotubes
ll4.me The Toxicology Of Carbon Nanotubes The widespread and increasing use of carbon nanotubes in scientific and engineering research and their incorporation into manufactured goods has urged an assessment of the risks and hazards associated with exposure to them. The field of nanotoxicology studies the toxicology of nanoparticles such as carbon nanotubes and has become a major growth area aimed towards risk assessment of nanoparticles. Compiled by a team of leading experts at the forefront of research, this is the first book dedicated to the toxicology of carbon nanotubes. It provides state-of-the-science information on how and why they are so potentially dangerous if breathed in, including their similarities to asbestos. The book examines various aspects of carbon nanotubes, from their manufacture and aerodynamic behaviour to their effects at molecular level in the lungs. It is invaluable to the many groups involved with research in this area, as well as to regulators and risk assessors.

Geography Club raises money for charter school

By Laurie Reiner November 8, 2012.

The Geography Club is raising money to pay for a bicycle rack for a local elementary school by selling coffee, hot chocolate and

baked goods.

The club had a table set up outside of the Social and Behavioral Science Building on Wednesday. This was the clubs second fundraiser for Ogden Preparatory Academy. It is raising money for two bike racks, one for the elementary school and one for the junior high.

I think its important because parents, instead of drive their kids to school, they have a healthier alternative way to transport their children to and from school, said Hannah Rice, a member of the Geography Club and a geography major with an environmental studies emphasis.

Were doing like a dollar suggested donation, but if people dont have a dollar, the change in their pocket works as well, said Shauna Wolfgram, who is also a member of the Geography Club with an emphasis in environmental studies. Wolfgram said someone traded them an orange for some food.

Rice said the club needs to raise around $1,000 in order to buy the bike racks. The first fundraiser was earlier this semester when they raised about $160, and Rice said they will probably raise about the same amount of money the second time. The club will have a few more fundraisers in the spring, and Wolfgram said they hope to raise the money by the end of spring semester.

Its a way of getting kids involved in sustainable transportation, said Heidi Hidalgo, a geography major who donated at the table.

Grounds for Coffee donated the hot chocolate and coffee for the fundraiser. There were also baked goods, such as muffins and rice crispy treats available to buy at the table.

Makeup from Karl Lagerfeld and Nars, ‘powerful anti-aging,’ and exotic scents

Beauty picks for Holiday 2012 By Cheche V. Moral Philippine Daily Inquirer

KARL Lagerfeld with Mon Shu Girl, the manga character he created for Shu Uemura

The big beauty launches happen in the run-up to the holidays. And fans of makeup, fragrance and skincare have a lot to look forward to in the next few weeks.

Karl Lagerfeld x Shu Uemura

Shu Uemura unveiled recently its long-awaited makeup collaboration with Karl Lagerfeld. Umu, Dusit Thanis Japanese restaurant, was awash in red Tuesday to usher in Mon Shu (My Darling) Girl, a Japanese manga-inspired character created by the fashion legend to represent his image for the collection.

Mon Shu sports a distinctly Asian blunt bob and has tiny red lips and big, red eyesmysterious rather than sinister, according to her creatorand is dressed in Lagerfelds likeness: white shirt and a black tie.

Nars x Andy Warhol Edie Set in 16-mm film canister

Lagerfeld has had a longtime affinity with the Japanese makeup brand. He said in promotional interviews that he began buying Shu Uemura eye shadows some 20 years ago. He uses the palette like he would use pastel crayons to color his sketches and designs.

I have never found this quality of pigment anywhere else, Lagerfeld said. I have used many other big brands, but Shu Uemuras are very refined and so fresh. I love this black that gives depth to my designs, and the red is very passionate. I use this red to make up the models in my designs and create the silhouette. In Japan the reds are always really vivid.

Lagerfeld met Shu Uemura in 2006, a year before the brands founder died. I really liked his pioneer spirit and the sparkling energy in his eyes, Lagerfeld said. I do feel that everyone has to invent his/her own thing, and I think Mr. Uemura created something that no one else could.

Anatomy of a Meningitis Outbreak

The fungal meningitis outbreak that sickened 414 people this fall was unprecedented -- first, because only people who received a tainted steroid injection were at risk; and, second, because the fungus wasn't known for making people sick, let alone causing a deadly inflammatory disease that's killed 31 people so far.

Health officials on the local, state and federal levels had to work together to trace the cause of the outbreak and get the word out to at-risk patients and their doctors.

"All of that coordination -- the right hand knowing what the left was doing -- has made a big difference in how quick we could come to an understanding of what was going on," said Dr. David Reagan, the chief medical officer in Tennessee, adding that the tainted drugs were recalled eight days after Tennessee physician Dr. April Pettit contacted the state health department about a patient with a suspicious illness.

Here is a timeline of how the outbreak played out:

Early September: The first fungal meningitis patients arrived in emergency rooms around the country in early September, but it took a clinician in Tennessee, Dr. April Pettit, to realize her patient with a mysterious illness was the beginning of a public health crisis. Reagan said she found fungus in the patient's spinal fluid.

Sept. 18: Pettit contacted the Tennessee Department of Health, including Dr. Marion Kainer, looking for similar patients. Her call set the investigation into motion, and she noted that the patient had recently received an epidural steroid injection.

Sept. 20: Two days later, the state health department called the CDC to report a fungal infection, noting that the patient had received an epidural steroid injection at the Saint Thomas Outpatient Clinic in August. Although the CDC had not heard about similar cases, it suggested Kainer visit the clinic. The same day, the clinic voluntarily closed. It has not reopened.

Sept. 21: The Tennessee Department of Health narrowed its list of possible causes to tainted steroid injectables from the New England Compounding Center (NECC) in Framingham, Mass., environmental contamination, or mishandling of equipment.

Sept. 24: Several other meningitis cases had been reported, and the Tennessee Department of Health reached out to Massachusetts's Department of health to learn more about NECC.

'Grey's Anatomy' recap: The Ballad of Meredith and Cristina

Image credit: KELSEY MCNEAL/ABC

BACK TOGETHER AGAIN Cristina (Sandra Oh) and Meredith (Ellen Pompeo) reunited during a touching hour of Grey's Anatomy.

It was undoubtedly by exactly perfect design, but Cristina uttered the most poignant line of Greys Anatomys ninth season so far in the last few seconds of last nights episode -- a line that sums up everything thats happened so far: Everyones dead, she said to Meredith without much fanfare, as the two best friends -- separated by half a country for five episodes -- embraced for the first time this fall.

The line was so simple and so fitting because, well, its true: Everyone has, indeed, died. Lexie. Sloan. And after last nights rather wrenching episode, titled Beautiful Doom, Dr. Feeny -- the old-man friend of Cristinas whose real name was Dr. Thomas -- also dropped dead, God bless his crusty, old soul. (Although the character death maybe isnt allllll bad for the actor who played him, William Daniels, since he may be getting his old gig back as Feeny on the recently announced Boy Meets World sequel spin-off that Disney has in the works.) All I have to say about all this continued theme of death is: We get it, Greys Anatomy powers! Youve got the power to kill people! No one is safe! Life is fragile! We should be scared! And all that jazz! But geez, its be nice if you stopped killing people. Death is exhausting, and there are really not many more tears to shed at Seattle Grace.

And maybe all the death has been a way to thin out the ranks on the over-populated show some. But Dr. Feeny was a new addition this season, so killing him, clearly -- as evidenced by the voiceover from him as his dead body was wheeled through the hospitals hallway -- wasnt to make room for other characters to have space to breath. It was to teach Cristina Yang to be a better person, which sorely needed to happen. (And will probably need to happen yet againand again.)

Truly, we can all take something away from the words he offered to Cristina Yang: Breathe, Dr. Yang, the voiceover from him near the end of the episode said, giving advice to the typically high-struck and unfriendly Cristina. Dont be crass. Youre skulking. Women of your generation are graceless. Its an affront to nature. Mediocre surgeons will see you and feel themselves wilting in your shadow. Do not shrink to console them. Do not look for friends here. You wont find them. None of these people have the capacity to understand you. They never will. If youre lucky, one day, when youre old and shriveled like me, youll find a young doctor with little regard for anything but their craft, and youll train them like I trained you. Until then, read a good book. You have greatness in you, Yang. Dont disappoint.

His death, however sad, was not unexpected. First off, he was really old. And actually, not long before Dr. Feeny dropped dead in the OR with Cristina, I had already thought he was dead once during the episode. Remember that scene when Cristina happened upon Feeny sun-bathing on a bench outside the hospital? I could have sworn he was dead then -- he looked it. But thankfully, Greys decided to pull his plug much more dramatically, with him literally keeling over mid-surgery. Cristinas sex friend Dr. Parker tried CPR on the immediately stiff man, while Yang had to finish her surgery. Also thankfully, considering everything, Yang was successful in her surgery. If it hadnt gone well, it might have sent me over the edge to have Feeny and the patient die minutes from each other.

NEXT: Meredith learns some lessons, too...

Cardiac Cell Therapy Phase III Trial to Treat Refractory Angina

RIO DE JANEIRO--(BUSINESS WIRE)--

CryopraxisTM/CellPraxis aims to start patient recruitment for its Phase III Refractory Angina Cell Therapy Brazilian arm clinical trial by the end of 2012 or early 2013. The phase IIA/B clinical trial study was completed in December 2011. These trials involved the use of a proprietary autologous stem cell formulation (MonocellTM) indicated for neoangiogeneses.

Safety and efficacy of this product was evaluated in patients with refractory angina, a no option disease condition, characterized by severe chest pain for which there is no efficient treatment available, says the President of both Companies, Eduardo Cruz.

ReACT, MonocellTMs derived product, showed evidence of safety and efficacy in our initial clinical trials. All patients included in this trial were classified as Class IV Angina in CCSAC* (the most severe class of chest pain). In the first group of patients, whose data was published**, there was a progressive and sustained improvement in angina symptoms, with 87.5% of the patients completing the clinical trial with a CCSAC score of 0 or 1.

Angina symptom relief began as early as 3 months post procedure with continuing improvement through the 18th month, suggesting that angiogenesis began early, and that it kept evolving 18 months after the procedure. Objective evaluation of stress myocardium perfusion (scintigraphic analysis), after 1 year of follow-up, gave indications of complete myocardial reperfusion in 75% of the patients, says Dr. Nelson Hossne, Medical Director of CellPraxis. Our conclusion was ReACT's specific cell formulation, MonoCell, had a direct correlation to myocardial neoangiogeneses.

Stem cell therapy using patient’s own cells after heart attack does not enhance cardiac recovery

Public release date: 6-Nov-2012 [ | E-mail | Share ]

Contact: Steve Goodyear sgoodyear@mhif.org 952-807-8365 Minneapolis Heart Institute Foundation

MINNEAPOLIS, MN November 6, 2012 Administering autologous stem cells obtained from bone marrow either 3 or 7 days following a heart attack did not improve heart function six months later, reports a new clinical trial supported by the National Institutes of Health. The results of this trial, called TIME (Transplantation In Myocardial Infarction Evaluation), were presented by Jay Traverse, MD of the Minneapolis Heart Institute Foundation Tuesday, Nov. 6, at the 2012 Scientific Sessions of the American Heart Association in Los Angeles.

The results of this trial mirror a previous, related study (LateTIME) which found that autologous bone marrow stem cell therapy given 2-3 weeks after a heart attack did not improve cardiac recovery. Both TIME and LateTIME were carried out by the Cardiovascular Cell Therapy Research Network (CCTRN), sponsored by the NIH's National Heart, Lung, and Blood Institute.

"The data presented by TIME do much to advance stem cell therapy research," said Jay Traverse, MD of the Minneapolis Heart Institute Foundation and Principal Investigator of this study. "While this study did not provide a demonstrated cardiac benefit after six months, we still learned a great deal. Together, TIME and Late TIME have shown that stem cell therapy is safe, and they have set a baseline in terms of quantity of stem cells, type of stem cells, and severity of heart attack."

TIME enrolled 120 volunteers (avg. age 57) between July 2008 and February 2011; the participants all had moderate to severe impairment in their left ventricle and had undergone coronary stent placement as treatment for the heart attack. The participants were randomly assigned to one of four groups: day 3 stem cell, day 3 placebo (inactive cells), day 7 stem cell, or day 7 placebo. The CCTRN researchers developed a method of processing and purifying the stem cells from the bone marrow of each volunteer to ensure everyone received a uniform dose (150 million stem cells).

Heart improvement was assessed six months after stem cell therapy by measuring the percentage of blood that gets pumped out of the left ventricle during each contraction (left-ventricular ejection fraction, or LVEF). The study found no significant differences between the change in LVEF readings at the six month follow-up in either the Day 3 or Day 7 stem cell groups compared with placebo or with each other; every group showed about a 3 percent improvement in LVEF. However, the researchers found that younger patients randomized to Day 7 had greater improvement in their LVEF compared to their placebo counterparts

"The lack of six-month improvement seen for TIME and, prior to that, LateTIME, does not mean stem cell therapy is not a viable post-heart attack strategy," said Traverse. "Because we have this data we can start to address some parameters; for example this therapy may work better in younger people, or maybe we need to use cells from healthy volunteers (allogeneic) since their cells may provide greater therapeutic benefit. There will also be upcoming studies using novel cell types which we look forward to using in future clinical trials."

UPDATE on Stem Cell Therapy 7 November 2012

UPDATE on Stem Cell Therapy

7 November 2012

The Department of Health (DOH) saw the necessity to cover regulations for Stem Cell therapy. Stem Cell therapy belongs to the category of Advanced Cell therapy which includes biologics and blood. Many countries around the world apply a risk-based approach to assess the quality, efficacy and safety of advanced cell therapy. In many countries, Stem Cell is considered an investigational intervention.

Stem Cell research employs both autologous (from same person) or allogenic (from another organism like animal or another human cell or tissue sample) method. Because there are many steps in the preparation of this lab and invasive procedure, there is therefore need to have a regulatory framework to protect Filipino citizens.

Important questions were asked: is there proof of concept in animal trials where stem cell can then be applied in humans? Is there a way to ensure quality and purity of the raw materials? How safe is the procedure? How many did not benefit from the procedure? If this were investigational procedure, how will human subjects be protected?

Sec. Enrique Ona convened a consultative working task force to provide recommendations on how to proceed in the early part of the year in response to queries and mushrooming of centers here and overseas. This led to the creation of a regulatory task force to oversee the appropriate steps that will ensure quality, efficacy and safety documentation of this intervention.
