Flatworms And Regeneration Research

Flatworms And Regeneration Research
Scientists have identified a gene in planaria--freshwater flatworms renowned for their regenerative abilities--that is key for maintenance of their stem cells. Because planarian stem cells share characteristics with those of humans, the work will aid researchers striving to understand how stem cells can be used to completely repair damaged tissues and organs.

Planaria have been studied for hundreds of years, but modern genomic techniques have given researchers new ways to delve into the molecular biology underlying planarian regeneration.Accordingly, Phillip Newmark and colleagues at the University of Illinois at Urbana-Champaign (UIUC) used a technique called "RNA interference" to stop a particular gene from producing its encoded protein.Without the protein, the planaria's stem cell population died out, and they lost the ability to regenerate.Now scientists will see if the gene plays a similar role in stem cells from other organisms.

All animals contain stem cells, which are unique because they have no specialized function but can mature into almost any cell type and do almost any job the body requires. In planaria, stem cells are responsible for the animal's ability to regenerate its entire body, even from small very small bits. Planaria are popular for introductory biology experiments because if one is chopped in half, two grow back.In fact, only 1/279th of a planarian is needed to regenerate a complete worm.........

A Digital Take On The Streets Where We Live

A Digital Take On The Streets Where We Live
A walk down the street may someday be as rich with information as the web, thanks to the emergence of location-aware technology.

Not surprisingly, MIT is at the vanguard of this movement with a project called Electronic Lens (eLens), an initiative of the MIT Media Lab. Headed by William Mitchell and Federico Casalegno, eLens is defined by its focus on benefits for local citizens.

Several research and commercial projects are also exploring the potential of location-aware services. Most rely on a tagging system - for example, physical tags attached to buildings - that can then be scanned and read by mobile camera phones.

eLens is exploring the next wave of communications technology - building interactions that depend on where you are and what you want to know or say. In the eLens team's vision, you could aim your mobile phone at your child's school and start a voice thread to discuss cuts in after-school programs. Or you could let passersby know that the local folk music club serves great vegetarian meals.

The project began with a metaphor, that of an electronic lens that can be aimed at civic institutions and a "viewfinder" that makes these institutions more transparent. Pointing eLens at a train station, for example, might let you retrieve the day's schedule for different tracks. Pointing it at a museum might list current exhibits and upcoming lectures.........

Almost Half Of Kids With ADHD Not Treated

Almost Half Of Kids With ADHD Not Treated A large number of children who could benefit from ADHD medications don't get them.
In contrast to claims that children are being overmedicated for attention-deficit/hyperactivity disorder (ADHD), a team of researchers at Washington University School of Medicine in St. Louis has found that a high percentage of kids with ADHD are not receiving treatment. In fact, almost half of the children who might benefit from ADHD drugs were not getting them.

"What we found was somewhat surprising," says Richard D. Todd, M.D., Ph.D., the Blanche F. Ittleson Professor of Psychiatry and professor of genetics. "Only about 58 percent of boys and about 45 percent of girls who had a diagnosis of full-scale ADHD got any medicine at all".

Much has been written about the increasing number of children taking drugs for ADHD. One study found that the percentage of elementary school children taking medicine for ADHD more than tripled, rising from 0.6 percent in 1975 to 3 percent by 1987. Another study reported that the number of adolescents taking ADHD drugs increased 2.5 fold between 1990 and 1995. And many reports have noted a rapid increase in the U.S. manufacture of the stimulant drug methylphenidate - usually sold under the brand names Ritalin or Concerta.

The researchers studied 1,610 twins between the ages of 7 and 17. Of those, 359 met full criteria for ADHD: 302 boys and 57 girls. The total number of boys in the sample was 1,006, and 604 girls were included.........

How Religious Garment Defines a New Generation of Women

How Religious Garment Defines a New Generation of Women Image courtesy of Amicalmant.ca
There's no argument that the hijab, a scarf that covers the head, hair, neck and ears, is a religious symbol that visibly separates young Muslim American women from their contemporary peers. But a number of who wear it say the covering is a boundary that's helping them carve out their own place in the Western world, yet it also bridges them with their family's traditions and values. The findings are from a paper by Rhys Williams, professor of sociology at the University of Cincinnati, and Gira Vashi, a research assistant at the University of Illinois, Chicago. Their paper, titled "Hijab and American Muslim Women: Creating the Space for Autonomous Selves," will be presented at 8:30 a.m. Sunday, Aug. 13, at the 101st annual meeting of the American Sociological Association in Montreal, Canada.

"There are multiple meanings to the hijab as a religious and social symbol; it often serves well those who wear it," states the paper. "It provides a clear identity marker at a life-course transitional time, and it provides culturally legitimate space for young women who are formulating new Muslim American identities and lives".

The research comes from the larger Youth and Religion Project - led by Williams and Stephen Warner, professor of sociology at the University of Illinois in Chicago. The sociologists started the project in 1999, conducting interviews and focus groups with Chicago area college-age students who represented an array of cultures and religious groups. The researchers' intent was to find out the young people's motivation in joining the organizations - how they utilized the organizations and how they benefited - which has been rarely studied, as per Williams.........

No advantage for four-drug antiretroviral regimen

No advantage for four-drug antiretroviral regimen
Adding a fourth drug to an antiretroviral regimen for the initial treatment of HIV-1 did not lead to significant differences in reducing HIV levels in the blood, time to virologic failure, adverse events or drug resistance over 3 years, according to a study in the August 16 issue of JAMA, a theme issue on HIV/AIDS.

Roy M. Gulick, M.D., M.P.H., of Weill Medical College of Cornell University, New York, presented the findings of the study today at a JAMA media briefing at the International AIDS Conference in Toronto.

The current standard of care for initial treatment of human immunodeficiency virus 1 (HIV-1) infection is a three-drug antiretroviral regimen, which can suppress viremia (presence of HIV in the blood), increase CD4 cell counts, delay clinical progression, and improve survival, according to background information in the article. Some researchers have suggested that adding drugs to the 3-drug regimens could improve antiretroviral activity. However, additional drugs increase complexity, the potential for toxicity, and costs, and prior studies comparing 3- and 4-drug antiretroviral regimens have shown inconsistent results.

Dr. Gulick and colleagues conducted a study to determine whether a 4-drug regimen would demonstrate better antiretroviral activity than the standard 3-drug regimen. The AIDS Clinical Trials Group (ACTG) A5095 study included 765 HIV-1infected patients who had not previously received treatment for HIV-1. The trial was a randomized, double-blind, placebo-controlled study, with enrollment and follow-up conducted from March 2001 to March 2005. The study participants received either the medications zidovudine/lamivudine plus efavirenz (3-drug regimen) or zidovudine/lamivudine/abacavir plus efavirenz (4-drug regimen).........

Rapid expansion of HIV treatment

Rapid expansion of HIV treatment
A massive scale-up of HIV/AIDS treatment programs at urban primary care sites in Zambia has produced favorable patient outcomes, demonstrating that expansion of such programs in sub-Saharan Africa is feasible, with good results, according to a study in the August 16 issue of JAMA, a theme issue on HIV/AIDS.

Jeffrey S.A. Stringer, M.D., of the Centre for Infectious Disease Research in Zambia, Lusaka, and the University of Alabama at Birmingham, presented the findings of the study today at a JAMA media briefing at the International AIDS Conference in Toronto.

Zambia's 11.5 million residents are among the world's poorest and most severely affected by acquired immunodeficiency syndrome (AIDS), according to background information in the article. About 16 percent of the adult population is infected with human immunodeficiency virus 1 (HIV 1), including 22 percent in the capital city Lusaka. In 2003, more than 90,000 Zambians died of HIV disease. Historically, only the wealthiest citizens have had access to antiretroviral therapy (ART) for HIV through private medical practices.

The Zambian Ministry of Health, aiming to provide public access to treatment, in 2002 started pilot ART distribution programs at two of the country's largest hospitals. The program filled almost immediately and in May 2004 expanded to four clinics in the Lusaka Urban District, which were staffed primarily by clinical officers and nurses. In the following 18 months, all fees for patients seeking care were eliminated, ART and laboratory tests were offered for free and the program expanded to 14 additional urban sites. "At the time of program initiation, there was widespread uncertainty that complex, long-term HIV care could be delivered in a setting with so few physicians and so little physical and technical resources," the authors write.........

Inside Views: Time To Rethink TRIPS?

Inside Views: Time To Rethink TRIPS? Fernando Barrio, Ph.D
In the aftermath of the late July collapse of the Doha Development Round negotiations at the World Trade Organization, some are looking for reasons and next steps. Much focus has been placed on the agriculture stalemate, but intellectual property issues also are a factor, especially for developing countries struggling with the 1994 WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). Fernando Barrio, a professor at London Metropolitan University, argues that reconsideration of the TRIPS agreement, and developed countries living up to the agreement, could go a long way in helping to save the larger WTO round.

"During the informal meeting of the Trade Negotiations Committee held on July 24th in Geneva, the WTO Director-General, Mr Pascal Lamy told heads of delegations in the informal meeting that he was going to recommend a "time out" and the suspension of the negotiations of the Doha Round. The Doha Round, the Doha Development Round, was started in November 2001 with the declaration of the Fourth Ministerial Conference in Doha, Qatar, and included negotiations on agriculture and services, both of interest for developing and developed countries. But, it can be argued that by focusing on development, the Doha Round was supposed to correct the asymmetries and inequities embedded in the result of the Uruguay Round, especially evident in the spirit, text and implementation of the Trade Related Aspects of Intellectual Property Rights Agreement, or TRIPS.........

Has E3 been Comdex'ed?

Has E3 been Comdex'ed?
According to the exclusive story from Next Generation, in the next 48 hours there will be an announcement on the cancellation of E3, which "in its present form, has been cancelled for next year and the foreseeable future." According to ARS Technica, the show is not being cancelled but rather downsized, due to the show-within-a-show that E3 was becoming: it was the back channel meetings that were the real events.

Okay, I came back from the last E3 all full of fun and excitement. Nothing is more exciting that seeing a big show, a la Comdex. The buzz, the excitement, the press. it's like CES is.

But, the other flipside is that working at the last CES, it became apparent that the show has become too big - and, that is pretty much what killed Comdex. Not that that is going to stop me from going to CES, but it will be for client work again. Just not that into Vegas to go for my own enjoyment.

Did I get that vibe at E3? No, because if I can walk a show floor in a day, it's not too big. :) And, while I was there for work, it was a different vibe. The PR people I ran into where busy - as a whole - and I did catch a few TV crews. Joystiq has a interesting take on the news - from a journalist standpoint, gamer standpoint and sorta corporate standpoint. Plus, E3 is not in the bowels of Vegas, but rather downtown LA. It's a more entertainment show feel, celebrity and product driven.........

Stranger in a Strange Land

Stranger in a Strange Land
This past weekend was BlogHer. I only was able to make it down for the Saturday sessions, but overall, I think it was a great event. In a sentence, it was the most valuable blogging-related event I have attended in the past year.

Now, some might think this is a little overblown, but, well, let them choke on their own bile. The event was how such blogging events should be: the newbies and the veterans getting together to discuss blogging and blogging practices. This is the only time that I have not seen the newbies attacked as idiots or undeserving the veterans attention, but rather working together to make the community better. Let me ask you: is that such a bad thing?

As others have noted, there was hugging and kissing and giggling - but that was pretty much just me, as I tend to hug and kiss people I know hello. And, well, I got to meet a lot of people that I read, but have not seen yet in person, or people that I met at the conference or people that are friends: Nellie Lide, Teresa Valdez Klein, Toby Bloomberg, Susan Getgood, Amy Gahran, Josh Hallett, Erin Caldwell, Robert Scoble, Stacy Libby. the list goes on and on, and the people that I forgot, I apologize.

And, well, Lisa and Elisa and Jory did a great job - and that's not a shock. Yep, me talking to Jory and Elisa.........
