Attempts to develop defined in vitro culture systems for the growth, reproduction and development of free-living nematodes have yielded much basic information about their nutritional requirements and biochemistry. Requirements for sterol and heme have been identified suggesting that some nematodes lack de novo synthesis of these molecules. Possible pathways of metabolism of these nutritional re...

BACKGROUND Indicators to predict healthcare-associated infections (HCAI) are scarce. Malnutrition is known to be associated with adverse outcomes in healthcare but its identification is time-consuming and rarely done in daily practice. This cross-sectional study assessed the association between dietary intake, nutritional risk, and the prevalence of HCAI, in a general hospital population. MET...

the beet armyworm spodoptera exigua (hübner) is a serious and economically important pest of solanaceous crops worldwide. the nutritional indices of this pest on three host plants including pepper capsicum frutescens, eggplant solanum melongena and tomato solanum lycopersicum were determined under laboratory conditions at 26 ± 1 °c, 60 ± 5% rh and 16: 8 (l: d) h. the highest relative consumptio...

Accessible online at: www.karger.com/ddi Nutritional therapy, once a cornerstone of medical treatment, has lost its attractivity in favor of drug treatment, molecular genetic interventions or other high-tech therapies. As a consequence, data about nutritional status or dietary habits are missing in many patient charts. This development reflects the opinion of many doctors that nutrition does no...
