Communications to the Editor not have active Pneumocystis carinii pneumonia (PCP). All of these patients had a history of single or recurrent episodes of PCP and were receiving aerosolized pentamidine isethionate as prophylaxis against recurrence of PCP It was suspected that the pneumothoraces were caused by coughing due to the irritative effect of pentamidine therapy on the airways superimpose...
In order to evaluate morpho-physiological responses of hybrid corn KSC750 to water stress at various stages of growth, a field experiment was conducted at the Pasargad region (northwest Fars) in 2010. The experiment carried out as a randomized complete block design, with 3 replications. In this study, corn growth period was divided into three phases: the establishment of plant to tasseling (pha...
In a multicenter cooperative controlled study, individual test, accuracy, and precision control values were determined for 75-mug ticarcillin disks with Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853.
BACKGROUND Cardiovascular magnetic resonance (CMR) T1 mapping indices, such as T1 time and partition coefficient (λ), have shown potential to assess diffuse myocardial fibrosis. The purpose of this study was to investigate how scanner and field strength variation affect the accuracy and precision/reproducibility of T1 mapping indices. METHODS CMR studies were performed on two 1.5T and three 3...
Natural fibers are widely used as reinforcing material in composites. Pine needles can be used as natural fibers which are abundantly found in the hilly areas of India. A study on tensile test of pine needles and the crack analysis of pine needles short fiber reinforced composites has been presented in this paper.ASTM D638-10 standard is followed for tensile testing and a number of specimen is ...
This paper presents the rst-ever results of applying statistical parsing models to the newly-available Chinese Treebank. We have employed two models, one extracted and adapted from BBN's SIFT System (Miller et al., 1998) and a TAGbased parsing model, adapted from (Chiang, 2000). On sentences with 40 words, the former model performs at 69% precision, 75% recall, and the latter at 77% precision a...
this experiment was conducted to investigate the digestibility and fermentation parameters of diets containing flower, pod with seed and leaf of siris in sheep by two-step digestion and gas production methods. the experimental diets were including zero, 25, 50, 75 and 100 percent of siris flower, pod and leaf. the result showed that gas production potential of diet containing 50 percent leaf wa...
Owing to the overlapping absorption bands of hemoglobin and bilirubin, spectrophotometric determination of plasma free hemoglobin has been plagued by the interference of bilirubin when the latter is present in significant concentrations. To resolve this problem, bilirubin oxidase from Myrothecium verrucaria has been used to remove bilirubin in icteric samples. The enzyme converts bilirubin to b...
The performance characteristics are reported for a serum cortisol assay using the GAMMAFLO Automated Assay System, an automated continuous-flow system for radioimmunoassay (RIA). This automated system utilizes a combination of continuous-flow methodology and column chromatography techniques. The cortisol assay studied had a standard curve range of 10.0 to 500 microgram per L. The intra-assay an...
BACKGROUND Idiopathic pulmonary fibrosis is a chronic progressive disorder with a poor prognosis. METHODS We conducted a double-blind, randomized, placebo-controlled multicenter study that assessed the effectiveness over one year of a high oral dose of acetylcysteine (600 mg three times daily) added to standard therapy with prednisone plus azathioprine. The primary end points were changes bet...
