The relationship between the structure of the T cell antigen receptor (TCR)-CD3 complex and development of NK1.1+ T cells was investigated. The TCR complex of freshly isolated NK1.1+ TCR-alpha/beta+ thymocytes contained CD3 zeta homodimers and CD zeta-FcR gamma heterodimers, whereas that of the majority of NK1.1- T cells did not contain FcR gamma. The function of CD3 zeta and FcR gamma in the d...
Recent European legislation adopts the concept of Full-cost recovery (FCR) as the guiding line for pricing of environmental services. In this paper, the meaning of the FCR concept is analysed and the economic rationale for its application is discussed. The basic idea developed is that FCR is a misleading concept, since costs are by definition recovered, and the problem becomes to assess how it ...
This experiment was conducted to investigate the effect of the form of diets with different levels of protein and energy on broilers performance at the end of the third week. A total of 2800 male broiler chicks were fed with two forms of diet (mash and crumble-pellet), two levels of protein (23% and 21% CP), and two levels of energy (3200 and 3000 Kcal/Kg ME) from 1 to 21 days of age. The bodyw...
OBJECTIVE In patients with acute myocardial infarction (AMI), estimation of infarct size from the early markers, fatty acid-binding protein (FABP) and myoglobin (MYO), usually assumes average (fixed) rate constants (FCR) for protein clearance from plasma. However, individual variation in FCR is large. Renal dysfunction causes slower clearance of FABP and MYO from plasma and, hence, overestimati...
The production and catabolism of very low density lipoprotein triglycerides (VLDL-TG) were determined in 11 index patients with primary hypertriglyceridemia and in their 70 first-degree relatives. In the probands the mean value for VLDL-TG production rate was twice normal, and the mean fractional catabolic rate (FCR) was reduced to 50% from normal. A similar kinetic pattern was also observed in...
In sea cage fish farming, production quotas aim to constrain the impact of fish farming on the surrounding ecosystem. It is unknown how these quotas affect economic profitability and environmental impact of genetic improvement. We combined bioeconomic modelling with life cycle assessment (LCA) to calculate the economic (EV) and environmental (ENV) values of thermal growth coefficient (TGC) and ...
BACKGROUND Registries of individuals at risk for hereditary cancer syndromes are an invaluable resource for cancer research, yet little is known about the predictors of enrollment in hereditary cancer registries. We sought to identify the factors that characterize individuals who enroll versus those who decline participation in a Familial Cancer Registry (FCR). We also sought to identify the fa...
Granulomatosis with polyangiitis (Wegener's) is a rare autoimmune neutrophil-mediated vasculitis that can cause renal disease and mucosal manifestations. Antineutrophil cytoplasmic antibodies (ANCA) are present in many patients, vary in level over time, and induce neutrophil activation through engagement with Fc receptors (FcRs). Given roles for FcRs in ANCA-mediated neutrophil activation and I...
Feed represents the major cost of chicken production. Selection for improving feed utilization is a feasible way to reduce feed cost and greenhouse gas emissions. The objectives of this study were to investigate the efficiency of genomic prediction for feed conversion ratio (FCR), residual feed intake (RFI), average daily gain (ADG) and average daily feed intake (ADFI) and to assess the impact ...
In 80 controls latencies of flexor carpi radialis (FCR) and in 94 controls latencies of soleus H-reflexes correlated well with length of the extremity, body height and age. Multiple regression equations using latency as a variable dependent on age and body height can be best used in practice when both reflexes are employed for demonstration of proximal pathology. The majority (69%) of 93 patien...
