abstract improving nitrogen use efficiency (nue) is an important objective of the agroecosystem management. a field experiment was conducted to study the effect of different competition patterns on nitrogen balance in the wheat agroecosystem. experimental design was split–plot based on randomized complete blocks with four replications. the main plots consisted of different nitrogen rates (i.e. ...

background: cardiac risk assessment with myocardial perfusion imaging (mpi) is a common practice for some elderly breast cancer patients who are candidates for operation. in rare cases the tumor may become visible in the images. case presentation: this is the report of a case with a huge slow-growing breast tumor suspicious for malignancy and presenting with methoxy-isobutyl-isonitrile (mibi) u...

the study applied an isolated brevibacterium sp. (mtcc 10313) for bioremediation of zn, cu, mg and pb in domestic sewage. batch culture experiments were performed on both the fresh and stale sewage samples with glucose supplementation of 1-8g/l. nutrient broth medium was prepared, sterilized and ph adjusted to 6.5-6.8. 1% of the brevibacteria sp. stock was inoculated into the broth and maintain...

Insulin-stimulated peripheral glucose uptake and insulin-induced renal tubular sodium reabsorption were investigated in normotensive men with a family history of hypertension (relatives, n = 35) compared with age- and body mass index-matched normotensive men with no family history of hypertension (controls, n = 23). The effect of insulin on the renin-aldosterone system was also studied. The eug...

The aim of this study was to characterize changes in maximal oxygen uptake over several years and to elaborate current reference values of this index based on determinations carried out in large and representative groups of top Polish rowers. For this study 81 female and 159 male rowers from the sub-junior to senior categories were recruited from the Polish National Team and its direct backup. ...

BACKGROUND Colonoscopic screening is recommended for first-degree relatives of patients diagnosed with colorectal cancer (CRC) or colorectal adenomatous polyps (CAP) before the age of 60 years. This has the potential to reduce CRC-related morbidity and mortality, but uptake is currently inadequate. METHODS The aim of the study was to compare the effectiveness of standard information versus a ...

BACKGROUND To investigate whether an apoptotic process demonstrated by (99m)Tc-annexin-V ((99m)Tc-AV) uptake correlates with left ventricular remodeling (LVR) after myocardial infarction, we assessed (99m)Tc-AV uptake in rat model of myocardial ischemia and reperfusion. METHODS The left coronary artery (LCA) of 15 rats was occluded for 20 to 30 min, followed by reperfusion. After 2 weeks, (99...

for the Assessment of Glioma Proliferation We read the interesting recent article by Kato et al concerning the assessment of glioma metabolic activity by positron-emission tomography (PET). The authors evaluated the type, grade, and proliferation index of 95 primary glioma cases by simultaneous [F] fluorodeoxyglucose (18F-FDG), C-methionine (MET) and C-choline (CHO) PET. Their results in astroc...

Statement of problem: Condylar hyperplasia of the mandible is a self limiting abnormality which can cause facial asymmetry, temporomandibular joint (TMJ) dysfunction and esthetic problems. Treatment planning is based on the results of isotope scanning, clinical findings and patient age. Single photon emission tomography (SPECT) is considered to be a sensitive method in the calculation of condyl...

Evidence such as systematic reviews or clinical practice guidelines are information products, and clinicians are consumers of those products; their current proliferation but low uptake by consumers indicates an information oversupply. The costs and benefits of accessing and applying information are at least as important as are the costs and benefits of the treatments the information describes. ...
