Over time, however, this emergency response may fail to cope with the stress, and the cell activates a self-des...Long-term effects of carbon monoxide poisoning are an autoimmune reaction
... into what they call the "CO season" a time when faulty furnaces and other mechanical mishaps lead to a spike in cases of carbon monoxide (CO) poisoning.

Brain damage occurs...... keep good time and runs too fast because it has a faulty spring balance. "What we are showing is that circadian clocks are composed of interlocking feedback loops," says Kay. The overlapping feedback, says Kay, is probably there for a number of reasons.

In this scenario, early exposure leads to more severe defects and sometimes death, while later expos...Last of known genes identified in complex obesity syndrome
...by taking advantage of their recent discovery that faulty cellular structures called cilia are behind the problems seen in BBS patients, the researchers were able to zero in on the disease-causing gene. Cilia are found on many different types of cells and can either act like antennae, sensing important sig...Scientists suggest framework for epigenetics in common disease
