Researchers find worm index closely associated with a nation's human development index

2015-04-30
(Press-News.org) HOUSTON - (April 30, 2015) - With the Millennium Development Goals established by the United Nations in 2000 coming to an end in 2015, and the new Sustainable Development Goals now in the works to establish a set of targets for the future of international development, experts at Baylor College of Medicine have developed a new tool to show why neglected tropical diseases, the most common infections of the world's poor, should be an essential component of these goals.

Using World Health Organization data for the number people at risk of parasitic worm infections in each of the largest nations and comparing this number to each nation's population, Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine, and Dr. Jennifer R. Herricks, postdoctoral fellow at Baylor, developed the worm index, which they found to have a strong association with a nation's human development index, a summary measure of average achievement in key dimensions of human development.

Their work was published today in PLOS Neglected Tropical Diseases.

"Through this paper, we've shown how the major neglected tropical diseases, which include intestinal worm infections, schistosomiasis and lymphatic filariasis, are intimately tied to human development," said Hotez, who also is Texas Children's Hospital Endowed Chair of Tropical Pediatrics and president of the Sabin Vaccine Institute.

"We found a very tight association between the worm index of a country and the human development index. The higher the worm index, the lower the human development index."

Parasitic worm infections affect millions of people and can cause long-term, chronic and disabling diseases.

"Because decreased human development is related to increased burden of parasitic worm infections, we recommend that serious consideration should be given to parasitic worm infections and other neglected tropical diseases when trying to attain goals that will ultimately improve human development; for example, when implementing the sustainable development goals," said Herricks, postdoctoral fellow in Disease and Poverty at the National School of Tropical Medicine at Baylor, who is also with Rice University's James A. Baker III Institute for Public Policy.

Fossils help identify marine life at high risk of extinction today

Fossils help identify marine life at high risk of extinction today
2015-04-30
A detailed study of marine animals that died out over the past 23 million years can help identify which animals and ocean ecosystems may be most at risk of extinction today, according to an international team of paleontologists and ecologists. In a paper to be published in the May 1 issue of the journal Science, researchers from the University of California, Berkeley, and other institutions report that worldwide patterns of extinction remained remarkably similar over this period, with the same groups of animals showing similar rates of extinction throughout and with a ...

Sustainability progress should precede seafood market access, researchers urge

2015-04-30
Demand for seafood from wild fisheries and aquaculture around the world has nearly doubled over the past four decades. In the past several years, major retailers in developed countries have committed to source their seafood from only sustainably certified fisheries and aquaculture, even though it is not clear where that supply will come from. A team of researchers led by the University of California, Davis, has focused its attention on fishery improvement projects, or FIPs, which are designed to bring seafood from wild fisheries to the certified market, with only a promise ...

Optimizing treatment protocols when diagnostics are costly

Optimizing treatment protocols when diagnostics are costly
2015-04-30
HIV-1 continues to spread globally. While neither a cure, nor an effective vaccine are available, recent focus has been put on 'treatment-for-prevention', which is a method by which treatment is used to reduce the contagiousness of an infected person. A study published this week in PLOS Computational Biology challenges current treatment paradigms in the context of 'treatment for prevention' against HIV-1. Sulav Duwal, Max von Kleist and their collaborators develop and employ optimal control theory to compute and assess diagnostic-guided vs. pro-active treatment strategies ...

Waking proteins up from deep sleep to study their motions

2015-04-30
Proteins inside a cell are in constant motion, changing shape continuously in order to carry out their functions. In addition, their multiple component atoms each have individual patterns of motion, making the entire protein a system of non-stop highly complex movement. Understanding how a protein moves is the key to developing drugs that can efficiently interact with it. But because of this complexity, protein motion has been notoriously difficult to study. Scientists at EPFL, IBS-Grenoble, and ENS-Lyon, have developed a new method for studying protein motion by first ...

Fossils inform marine conservation

Fossils inform marine conservation
2015-04-30
The fossil record helps to predict which kinds of animals are more likely to go extinct. When combined with information about hotspots of human impacts and climate-change predictions, Smithsonian scientists and colleagues pinpoint animal groups and geographic areas of highest concern for marine conservation in the May 1 issue of Science magazine. "Just as some groups of people are more prone to health problems like diabetes or heart disease, we can tell from the fossil record which groups of animals are naturally more likely to go extinct," said Aaron O'Dea, paleontologist ...

Meet the beetle that packs a machine gun

Meet the beetle that packs a machine gun
2015-04-30
If you thought that a beetle with a machine gun built into its rear end was something that only exists in sci-fi movies, you should talk to Wendy Moore at the University of Arizona. Many beetles secrete foul-smelling or bad-tasting chemicals from their abdomens to ward off predators, but bombardier beetles take it a step further. When threatened, they combine chemicals in an explosive chemical reaction chamber in their abdomen to simultaneously synthesize, heat and propel their defensive load as a boiling hot spray, complete with "gun smoke." They can even precisely ...

Dam removal study reveals river resiliency

2015-04-30
SEATTLE, Wash. -- More than 1000 dams have been removed across the United States because of safety concerns, sediment buildup, inefficiency or having otherwise outlived usefulness. A paper published today in Science finds that rivers are resilient and respond relatively quickly after a dam is removed. "The apparent success of dam removal as a means of river restoration is reflected in the increasing number of dams coming down, more than 1,000 in the last 40 years," said lead author of the study Jim O'Connor, geologist with the U.S. Geological Survey. "Rivers quickly erode ...

How some beetles produce a scalding defensive spray

2015-04-30
CAMBRIDGE, Mass--Bombardier beetles, which exist on every continent except Antarctica, have a pretty easy life. Virtually no other animals prey on them, because of one particularly effective defense mechanism: When disturbed or attacked, the beetles produce an internal chemical explosion in their abdomen and then expel a jet of boiling, irritating liquid toward their attackers. Researchers had been baffled by the half-inch beetles' ability to produce this noxious spray while avoiding any physical damage. But now that conundrum has been solved, thanks to research by a ...

New origin theory for cells that gave rise to vertebrates

2015-04-30
The vivid pigmentation of zebras, the massive jaws of sharks, the fight or flight instinct and the diverse beaks of Darwin's finches. These and other remarkable features of the world's vertebrates stem from a small group of powerful cells, called neural crest cells, but little is known about their origin. Now Northwestern University scientists propose a new model for how neural crest cells, and thus vertebrates, arose more than 500 million years ago. The researchers report that, unlike other early embryonic cells that have their potential progressively restricted as ...

Chapman University research on the yoga market from 1980 to the present

2015-04-30
ORANGE, Calif. - Researchers in Chapman University's Argyros School of Business and Economics and their collaborators have just published a study on the evolution of yoga in the marketplace. Assistant Professor Gokcen Coskuner-Balli, Ph.D., co-authored the study, which examined how the meaning of yoga transformed in the past three decades. The results show that yoga became decreasingly associated with spirituality and increasingly associated with medicine and fitness. The study argues that the shift in the meanings are due to the changes in how yoga gurus are trained, market ...
