A method for use in high-throughput screening of bacteria for the production of long-chain hydrocarbons and ketones by monitoring fluorescent light emission in the presence of Nile red is described. Nile red has previously been used to screen for polyhydroxybutyrate (PHB) and fatty acid esters, but this is the first report of screening for recombinant bacteria making hydrocarbons or ketones. Th...

Rowland, Neil E., and Kenneth R. Morian. Roles of aldosterone and angiotensin in maturation of sodium appetite in furosemide-treated rats. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1453–R1460, 1999.— When rats are treated with furosemide, there is a rapid natriuresis. However, increased sodium appetite does not occur until some time later. One hypothesis to explain this d...

BACKGROUND Cachexia is a hallmark of pulmonary tuberculosis and is associated with poor prognosis. A better understanding of the mechanisms behind such weight loss could reveal targets for therapeutic intervention. The role of appetite-regulatory hormones in tuberculosis is unknown. METHODS AND FINDINGS 41 subjects with newly-diagnosed pulmonary TB (cases) were compared to 82 healthy controls...

Background: Protein-energy malnutrition (PEM) is a common complication in pediatric patients with chronic kidney disease (CKD). Components incorporated in the regulation of appetite and body composition appear to be of the focus in renal insufficiency and may influence the CKD-associated PEM. The purpose of this study was to investigate plasma levels of appetite-regulating hormones and their co...

Acknowledgements Authors are indebted to Dr. Diana Quiñones Tapia for expert neuroradiological assistance during the human studies and to Mr. Javier Pérez CSIC, for careful, professional drafting of the illustrations. Abstract Hypothalamic appetite regulation is a vital homeostatic process underlying global energy balance in animals and humans, its disturbances resulting in feeding disorders wi...

The Nile crocodile (Crocodylus niloticus) is an ancient icon of both cultural and scientific interest. The species is emblematic of the great civilizations of the Nile River valley and serves as a model for international wildlife conservation. Despite its familiarity, a centuries-long dispute over the taxonomic status of the Nile crocodile remains unresolved. This dispute not only confounds our...

BACKGROUND/OBJECTIVES Poor appetite in older adults leads to sub-optimal food intake and increases the risk of undernutrition. The impact of poor appetite on food intake in older adults is unknown. The aim of this study was to examine the differences in food intake among older community-dwelling adults with different reported appetite levels. DESIGN Cross-sectional analysis of data from a lon...
