it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...
INTRODUCTION Educational milestones are now used to assess the developmental progress of all U.S. graduate medical residents during training. Twice annually, each program's Clinical Competency Committee (CCC) makes these determinations and reports its findings to the Accreditation Council for Graduate Medical Education (ACGME). The ideal way to conduct the CCC is not known. After finding that d...
OBJECTIVE Identifying agreement between data for estimating maximum oxygen uptake obtained by a fitness test and the Polar S810 heart rate monitor. METHODS This was an observational agreement study comparing two methods for estimating VO(2max) (simultaneously and independently). Two protocols were applied to 46 athletes from the Universidad Nacional de Colombia who had been trained in enduran...
AIMS Chagas disease, caused by the protozoan Trypanosoma cruzi is endemic in Latin America, and may lead to a life-threatening inflammatory dilated, chronic Chagas cardiomyopathy (CCC). One third of T. cruzi-infected individuals progress to CCC while the others remain asymptomatic (ASY). A possible genetic component to disease progression was suggested by familial aggregation of cases and the a...
OBJECTIVE The objective of this study was to evaluate the antitumor effects of lurbinectedin as a single agent or in combination with existing anticancer agents for clear cell carcinoma (CCC) of the ovary, which is regarded as an aggressive, chemoresistant, histological subtype. METHODS Using human ovarian CCC cell lines, the antitumor effects of lurbinectedin, SN-38, doxorubicin, cisplatin, ...
BACKGROUND Trypanosoma cruzi ribosomal P proteins, P2β and P0, induce high levels of antibodies in patients with chronic Chagas' disease Cardiomyopathy (CCC). It is well known that these antibodies alter the beating rate of cardiomyocytes and provoke apoptosis by their interaction with β1-adrenergic and M2-muscarinic cardiac receptors. Based on these findings, we decided to study the cellular i...
PURPOSE To dosimetrically validate AcurosXB algorithm for Volumetric Modulated Arc Therapy (VMAT) in comparison with standard clinical Anisotropic Analytic Algorithm(AAA) and Collapsed Cone Convolution(CCC) dose calculation algorithms. METHODS AcurosXB dose calculation algorithm is available with Varian Eclipse treatment planning system (V10). It uses grid-based Boltzmann equation solver to p...
BACKGROUND AND OBJECTIVES Coronary collateral circulation (CCC) has been attributed as inborn bypass mechanisms supporting ischemic myocardium. Various factors have been postulated in CCC. Whole blood viscosity (WBV) has been an underappreciated entity despite close relationships between multiple cardiovascular diseases. WBV can be calculated with a validated equation from hematocrit and total ...
بازار جهانی محصولات کشاورزی استراتژیک مانند کنجاله سویا و گندم، تحت تاثیر نوسانات قیمت نفت قرار دارد و این موضوع بر تصمیمات سیاست گذاران و تولیدکنندگان این حوزه تاثیرگذار است. در این مقاله، با توجه به اهمیت ریسک های وارد شده بر قیمت نفت، سعی شده است تا تاثیر ریسک بازار نفت بر بازار محصولات کشاورزی مشخص گردد. به همین دلیل، بازده روزانه قیمت جهانی کنجاله سویا و گندم به عنوان مهمترین نهاده های کشا...
BACKGROUND There is momentum internationally to improve coordination of complex care pathways. Robust evaluations of such interventions are scarce. This paper evaluates the cost-utility of cancer care coordinators for stage III colon cancer patients, who generally require surgery followed by chemotherapy. METHODS We compared a hospital-based nurse cancer care coordinator (CCC) with 'business-...
