Circadian rhythm generation in the suprachiasmatic nucleus was modeled by locally coupled self-sustained oscillators. The model is composed of 10,000 oscillators, arranged in a square array. Coupling between oscillators and standard deviation of (randomly determined) intrinsic oscillator periods were varied. A stable overall rhythm emerged. The model(More)
Non-saleable milk (waste milk, WM) is contaminated with an undefined spectrum of potentially harmful pathogens and antimicrobial residues. The objective of this study was to determine the impact of feeding bulk milk (BM) or WM - both pasteurized or not - on calf performance, health and the antibiotic resistance of specific faecal bacteria. A total of 114(More)
The aim of this study was to investigate the impact of weight gain of calves within the first 3 weeks of life on health status and subsequent performance. Holstein bull calves were reared either intensively (IR; individual hutches and ad libitum milk feeding for the first 3 weeks of life; n = 24), or according to the established protocol [ER; 4 l milk/day(More)
Low-dose antacid treatment without and with additional ranitidine in the prevention of acute gastroduodenal stress ulceration in high-risk patients was compared in a randomized, double-blind clinical trial with endoscopic examination of the upper gastrointestinal tract before entry and after the 7-day study period. Of 67 patients who entered the study, 56(More)
Seven ELISAs, two westernblots and one immunofluorescence assay for serological detection of parvovirus-B19-infection were compared with regard to their sensitivity and specificity. All ten assays are commercially available and use recombinant proteins (VP1, VP2) from bacterial and eukaryotic expression systems and synthetic viral peptides as antigens. The(More)
