Ammonia fixation has been shown to proceed through at least three major pathways in ureotelic animals (1, 2). These are carbamyl phosphate synthetase, glutamic dehydrogenase, and glutamine synthetase. Perhaps the most significant means for removal of exogenous ammonia is by its conversion to urea (3). The initial step in this conversion is the production of carbamyl phosphate in the liver. Carb...

It is argued that M-theory compactifications on any of Joyce's Spin(7) holonomy 8-manifolds are dual to compactifications of het-erotic string theory on Joyce 7-manifolds of G 2 holonomy.

From measurements of tritium incorporation following the perfusion in situ of livers with blood enriched in 3HZ0, the rate of hepatic fatty acid and cholesterol biosynthesis in young nonfasted rats was found to be 7.0 and 0.09 pmoles per g of liver per hour, respectively. Newly synthesized fatty acids were utilized by liver in the same manner as has been shown by others for preformed fatty acid...

Rats fed a purified diet supplemented with erotic acid (1%) have gross alterations in their lipid metabolism that can be essentially nullified by further supplementation of the diet with adenine sulfate (0.25%), as described in the first paper of this series (1). Accompanying these changes are certain alterations in the metabolism of pyrimidine derivatives, which have been described in an earli...

This paper proposes a method for helping to identify adult web sites by using the image-content as means of detecting erotic material. The image content is classified by investigating probable skinregions, and extracting their feature vectors. These feature vectors are based on color-, texture-, contour-, placementand relative sizeinformation for a given region. The importance of the different ...

After emergence female houseflies were fed for 4 days on a diet containing r4C-erotic acid and 3H-thymidine-5-triphosphate, or 3H-leucine. Nucleic acids and ribosomes were then isolated from the ovaries and studied by MAK column chromatography and sedimentation analysis respectively. The ultraviolet absorption and radioactivity of the fractions were also measured. After MAK column chromatograph...

Experienced value representations within the human orbitofrontal cortex (OFC) are thought to be organized through an antero-posterior gradient corresponding to secondary versus primary rewards. Whether this gradient depends upon specific morphological features within this region, which displays considerable intersubject variability, remains unknown. To test the existence of such relationships, ...

Introduction. Extensive research suggests that long-term cigarette smoking is an independent risk factor for the introduction of sexual dysfunction in men. However, results of limited data investigating this relationship in women are mixed. No studies have examined the acute effects of tobacco or nicotine on physiological sexual response in women. Controlled experimental studies examining acute...
