Look, Ma! No pneumococcus!

Pneumococcal diseases, caused by the bacterium Streptococcus pneumoniae, include pneumonia and otitis media, which accounts for some 12 million doctor visits per year in the United States alone. Each year around the world, pneumococcus causes 1.2 million deaths due to pneumonia, 39% of which are in children under the age of five. In a three-year Phase III clinical trial involving 38,000 children, in which half of the infants received a new pneumococcal vaccine and half received a placebo vaccine, the new vaccine demonstrated an efficacy rate of 100% against bacterial meningitis and bacteremia, the two most deadly pneumococcal afflictions.

Working the bugs out of asthma.

Cockroach antigens (proteins found in the insects' feces, saliva, eggs, and shed cuticles) have been implicated as one of the leading causes of asthma among inner-city children. These antigens can trigger severe allergic reactions, and even tiny amounts can be potentially fatal to sensitive asthmatics.

Effect of oral alanine loads on plasma amino acids in oral contraceptive users and control women.

Plasma amino acids were determined before and after orally administered alanine loads in five women using an estrogen-containing oral contraceptive and four healthy female controls. Oral contraceptive users and significant reductions in fasting plasma valine, methionine, isoleucine, tyrosine, phenylalanine, histidine, glutamic acid, and alpha-aminobutyric acid. With the exception of alpha-aminobutyric acid, these differences between the two groups were eliminated within 3 hr of alanine ingestion. This effect was due to a gradual increase in the plasma amino acids of the oral contraceptive-treated women, plus no change or slight reductions in the controls.
