There is an increasing body of evidence that the pineal gland acts
as a neuroendocrine transducer, translating neural information about
environmental lighting condition into hormonal information. In the
rat, light controls the production of melatonin which acts via the
hypothalamic-hypophyseal pathway to control the function of the gonads,
A similar...
The pulmonary function scores of 250 male cigarette smokers
were compared with 406 lifetime nonsmokers. A Stead-Wells spirometer
was used to obtain forced vital capacity, forced expiratory
flow, forced mid-expiratory flow, and forced expiratory volume. All
individuals included in the sample were between. the ages of 20 and

Hemicellulose hydrolyzate contains many carbohydrate
fractions, the most abundant being xylose, arabinose, and
glucuronic acid. Under mild acid conditions (0.025 -
0.10 M sulfuric acid) and high temperatures (140°C to
200°C) the first two components form furfural through a
series of dehydration reactions. Unlike xylose and
arabinose, glucuronic acid must...
