In a head-to-head competition held 10 years ago, scientists at the National Institutes of Health tested two promising new types of vaccine to see which might offer the strongest protection against one of the deadliest viruses on earth, the human immunodeficiency virus (HIV) that causes AIDS. One vaccine consisted of DNA rings called plasmids, each carrying a gene for one of five HIV proteins. Its goal was to get the recipient’s own cells to make the viral proteins in the hope they would provoke protective reactions by immune cells. Instead of plasmids, the second vaccine used another virus called an adenovirus as a carrier for a single HIV gene encoding a viral protein. The rationale for this combination was to employ a “safe” virus to catch the attention of immune cells while getting them to direct their responses against the HIV protein.

One of us (Weiner) had already been working on DNA vaccines for eight years and was hoping for a major demonstration of the plasmids’ ability to induce immunity against a dreaded pathogen. Instead the test results dealt a major blow to believers in this first generation of DNA vaccines. The DNA recipients displayed only weak immune responses to the five HIV proteins or no response at all, whereas recipients of the adenovirus-based vaccine had robust reactions. To academic and pharmaceutical company researchers, adenoviruses clearly looked like the stronger candidates to take forward in developing HIV vaccines.

International Stem Cell Corporation (OTCBB:ISCO), http://www.internationalstemcell.com, and Sankara Nethralaya, http://www.sankaranethralaya.org, announced today commencement of a collaboration to develop ISCO's 'CytoCor™' stem cell-derived corneal tissue. The goal is to use CytoCor to treat corneal blindness and vision impairment. 'This is one more step in ISCO's stated plan of building its portfolio of therapeutic agents through strategic alliances throughout the world,' said Chairman, Ken Aldrich.

CytoCor consists of transparent human tissue derived from pluripotent human stem cells. These structures are produced in the laboratory and recent testing at Sankara Nethralaya and laboratories in the US has demonstrated a range of structural, biochemical and refractory properties characteristic of human cornea.

CytoCor may offer a first-in-class opportunity for high-quality, cost-efficient transplantation tissue for the 10 million people world-wide suffering from corneal vision impairment, particularly in India and the rest of Asia, as well as in Europe. Standardized tissues derived from pluripotent stem cells, such as the CytoCor tissue, could eliminate the current problem that corneal tissue derived from donors may harbor diseases that could be transferred from the donor to the recipient. It may also provide a much needed alternative to the use of live and extracted animal eyes in the $500+million market for safety testing of drugs, chemicals and consumer products.

According to Professor Dr. S. Krishnakumar, 'Sankara Nethralaya is dedicated to the development and application of new state-of-the-art ophthalmic technologies. The need for high-volume, high-quality human corneal tissue is substantial, not only in India but across Asia and much of Europe. We appreciate the opportunity to join ISCO in their pursuit to create a new standard of care for the treatment of human corneal disease.' Initially, Dr. Krishnakumar and his team will be using the CytoCor tissue in preclinical studies to explore the ability of the tissue to withstand sutures and bio-compatible glues in order to validate the potential of the tissue for use in animal or human clinical trials.

According to Dr. Geetha Krishnan Iyer, who is involved in the management of ocular surface disease at Sankara Nethralaya, 'The team at Sankara Nethralaya is pleased to collaborate with ISCO on stem cell-derived corneal tissue. In vitro studies to evaluate safety and efficacy of the tissue, as well as surgical feasibility tests will be carried out, following which there could be clinical application in lamellar keratoplasty using the above mentioned tissue. With improvements in surgical techniques over the past few years, the indications for anterior lamellar keratoplasty have expanded significantly. With high demand for donor corneal tissue for the same but limited availability, there is definitely scope for utilizing ISCO's corneal tissue following relevant tests.'

Jeffrey Janus, Senior VP of Operations at ISCO, states: 'This collaboration with the excellent team of scientists and clinicians at Sankara Nethralaya has already proven to be productive. Sankara's ophthalmology expertise and ISCO's cell culture capabilities constitute a perfect match to perfect and advance CytoCor tissue towards future use in treating corneal disease and injuries.'

The Los Angeles Times recently reported that the Center for Science in the Public Interest (CSPI) is planning to sue fast-food giant McDonald's if the company does not comply with its demands to remove toys from "Happy Meals". CSPI claims that marketing unhealthy food with toys is contributing to the childhood obesity epidemic and should be stopped immediately.

The announcement by CSPI comes just weeks after a California county banned not only toys but all other promotions aimed at children that involve McDonald's Happy Meals. By doing this, the county believes that children will be less attracted to fatty foods that are high in salt and calories.

According to the same article, back in April, Santa Clara County, California, also banned toy promotions from fast food meals sold in unincorporated parts of the county.

Spokesmen from McDonald's denied that Happy Meals are inherently unhealthy, citing the fact that the meals are of an appropriate size and that children have the option to swap out the fries and soda for apples and juice. They also explained that giving away toys with children's meals is part of the fun of a family dining experience.

Since 2008 when apples were first introduced as an option in Happy Meals, customers have ordered them more than 100 million times, illustrating that when given healthier options, customers often choose them for their children instead. Read more...
Cold symptoms

The abbreviation KPU stands for pyrroluria, which is a frequently disregarded metabolic disorder that may cause numerous unspecific symptoms. However, it is comparatively easy to treat. In general, KPU (a.k.a. pyrroluria, malvaria, or HPU) is a genetically determined anomaly of hemal production (an aspect of blood formation) which causes increased hemal pyrrole concentrations.

Normally, this substance does not circulate freely in the blood but is bound by bile acid and excreted through the intestines. In KPU-cases, however, crypto pyrrole is increasingly excreted in the urine – unfortunately along with vitamin B6, zinc, and manganese which the body lacks due to this process.
In combination with increased stress (e.g. acute viral rhinopharyngitis, burns, injuries/accidents, intestinal infections, or psychic stress) this causes a wide range of symptoms, such as:
disturbances of memory and sleep, erratic mood swings, depression, hair loss, proneness to infections, and chapped skin. There is also a possible relation to ADHD with children and juveniles. Read more...

(HealthDay News) -- The needle pricks involved in acupuncture may help relieve pain by triggering a natural painkilling chemical called adenosine, a new study has found.

The researchers also believe they can enhance acupuncture's effectiveness by coupling the process with a well-known cancer drug -- deoxycoformycin -- that maintains adenosine levels longer than usual.

"Acupuncture has been a mainstay of medical treatment in certain parts of the world for 4,000 years, but because it has not been understood completely, many people have remained skeptical," lead author Dr. Maiken Nedergaard, co-director of the Center for Translational Neuromedicine at the University of Rochester Medical Center, said in a news release. "In this work, we provide information about one physical mechanism through which acupuncture reduces pain in the body." Read more...
