Cartilage discovery offers arthritis hope

...hout the steel, the cartilage becomes mechanically weak and susceptible to wear and tear. "Eventually, the cartilage breaks down altogether and sufferers experience severe pain as the two ends of the bones rub against each other." The team's findings published in the journal Proceedings of the National...

Pet owners are sick more often and exercise less than other working-aged people

...han the rest. Perceived health of pet owners was weak more often than that of those not having a pet. Illnesses, such as high blood pressure, blood pressure disease, diabetes, ulcer, sciatica, migraine, depression, and panic attacks were more common among them. Socio-demographic background factors and r...

Deaths of severely malnourished children: identifying those most at risk

...ly deaths. These four signs were: slow heart rate, weak pulse volume, depressed level of consciousness, and delayed capillary refilling time (i.e. pressing a fingernail bed to blanch the finger, releasing it, and observing the time taken to recolor the nailbed). The researchers proposed that these finding...

Nano design adjustment may help find, clear some water contaminants

...acterization of what we have termed an off-center, weak charge-transfer interaction." Anions, of which notable examples include DNA, nitrate, pertechnetate, cyanide and chromate, play indispensable roles in biological and chemical processes, but they also can contribute significantly to environmental po...

A window on the environment from Tahoe to the ocean

... as El Nino events. In years when the upwelling is weak or ends early, ocean production dives, affecting fish and birds. Animals that move back and forth between the sea and land, such as migrating birds or salmon running upriver, may change in numbers or behavior -- changing how nutrients move around. ...

Researchers study role of natural organic matter in environment

...ick found that sodium and magnesium ions have very weak interactions with natural organic matter. Cesium interacts more strongly, but calcium has the strongest interaction with natural organic matter. The strength of the interactions of ions with natural organic matter is dependent upon multiple factors...

Gene-bender proteins may sway to DNA

...hat the DNA is able to bend or kink on its own, at weak points created by the transient opening of base-pairs, and that the protein recognizes and binds tightly to the bent DNA conformation." Conclusions by Ansari and her colleagues deviate slightly from the conventional dogma that it is the protein tha...

Theory of oscillations may explain biological mysteries

...be explained this way. Physicists know that even a weak coupling between oscillating systems can yield synchronized oscillations, a phenomenon that was studied with pendulums by the seventeenth century Dutch mathematician Christiaan Huygens. Biologists have only in recent years started to explore the impl...

Icelandic volcano caused historic famine in Egypt, says Rutgers-based team

...peratures to Laki, it also connected the dots to a weak monsoon the seasonal winds that bring the annual rains to southern Asia and northern Africa. The unusual cold in the North lessened the temperature contrast between the land and the oceans, upon which the monsoon winds rely for their development and...

Tweedle coat fashions stocky flies

...nk they strengthen the cuticle. Make one part too weak or too strong and the larvae end up resembling their namesake. Tweedles may be good targets for novel insecticides, the researchers say, because the gene family appears to be unique to insects. "We've discovered Tweedle genes in all insect spe...

Viral marker of human migration suspect

There are more than 14 subtypes of the virus, each primarily associated with different human populations such as African, Japanese, South Asian, and European. Population genetici...

Electronic chip, interacting with the brain, modifies pathways for controlling movement

The authors of study, titled "Long-Term Motor Cortex Plasticity Induced by an Electronic Neural Implant," were Dr. And...

Carnegie Mellon uses new imaging technique to discover differences in brains of people with autism

...observed in autism of narrowly-focused thought and weak coherence of different streams of thought," said Marcel Just, director of the Center for Cognitive Brain Imaging and a co-author of the latest study. "The new findings also provide supporting evidence for a new theory of autism that attributes the di...

Researchers add to understanding of how brain cells communicate

...oss the membrane, NR1/2D receptors respond even to weak inputs. In this paper, Johnson and Qian further elucidate how NR1/2D receptors do this. Johnson was most surprised to find that the magnesium ion, which strongly blocks the channels of NR1/2A receptors, flows much more easily in NR1/2D receptors. I...

Researchers discover new gene responsible for brittle bone disease

...structed their bodies to make either too little or weak collagen because of defects or mutations in one of the collagen genes, of which there are more than 20. The current study found a new gene, that when mutated, reduces the ability of a protein involved in collagen formation, called CRTAP (cartilage-as...

Gene linked to autism in families with more than one affected child

..., the researchers determined that the C version is weak at making the MET receptor protein, resulting in a two-fold reduction in gene expression compared to the other common G version of the gene, with presumably adverse consequences on brain development. Inheriting two copies of the C version boosted ri...

Study suggests earlier crop plantings could curb future yields

...her motivated the early plantings. "There is very weak or little to no correlation with springtime temperatures over the majority of the Corn Belt and these [earlier] planting dates," Kucharik says. Rather, other factors- - such as improved land management practices and advances in biotechnology - have b...

Association between neuroticism and risk for depression may be genetic

They concluded that this major dimension of personality has little to do with risk for depression. Previous studies in literature have reported that neuroticism or neuroticism-like traits have...

'The immediate priority for Governments and donors should be to invest in the training, deployment and retention of skilled attendants, especially midwives, who we know can make a huge diffe...
