Real-time monitoring of the economy is based on activity indicators that show regular patterns such as trends, seasonality and business cycles. However, parametric and non-parametric methods for signal extraction produce revisions at the end of the sample, and the arrival of new data makes it difficult to assess the state of the economy. In this paper, we compare two signal extraction procedures: Circulant Singular Spectral Analysis, CiSSA, a non-parametric technique in which we can extract components associated with desired frequencies, and a parametric method based on ARIMA modelling. Through a set of simulations, we show that the magnitude of the revisions produced by CiSSA converges to zero quicker, and it is smaller than that of the alternative procedure.

Background Contrast

A number of electrooptical techniques are described that discriminate against background fluorescence in biologic staining, whether from sample background or unbound excess stain. These techniques are based on the fluorescent decay lifetime difference between bound stain and the sample background or between the bound stain its free form. The fluorescence decay lifetimes may be measured either directly or in a combination gated photometry scheme to substantially enhance the sample background contrast. An alternative procedure uses the photochemical bleaching of fluorescent dyes under intense exposure to time discriminate with higher selectivity, sensitivity and in a more convenient fashion between diverse fluorescent molecules.

Purpose. To introduce a minimally invasive procedure, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), to obtain a pathologic evidence of a definite ocular sarcoidosis in a patient who initially presented with presumed ocular sarcoidosis with pulmonary involvement.Methods. An EBUS-TBNA procedure was performed at perihilar lymph nodes, subcarina, and right paratrachea of the patient and specimen obtained was sent for histocytopathological studies.Result. Histocytopathological findings revealed aggregates of epithelioid histiocytes forming a noncaseous granuloma, a hallmark of sarcoidosis.Conclusion. EBUS-TBNA should be considered an alternative procedure to provide cytohistopathology proven diagnosis of definite ocular sarcoidosis.

The growing demand for high quality soybean [Glycine max (L.) Merrill] seeds requires a precise seed quality control system from the seed industry. One way to accomplish this is by improving vigor testing. Cold test has been traditionally employed for corn seeds. However, it has also been used for other seed crops such as cotton (Gossypium spp.), soybean (Glycine Max), dry bean (Phaseolus vulgaris) and pea (Pisum sativum). This study was carried out with the objective of adjusting an alternative procedure for the cold test to determine soybean seed vigor. Six commercial soybean seed lots of the cultivar BRS 133 were used. The physiological potential of the seed lots was evaluated by germination on paper towel and sand box, seedling field emergence, tetrazolium, accelerated aging and electrical conductivity tests. Seed moisture content was also determined. The temperature used for the cold test procedures was 10ºC during five days. Four cold test procedures were evaluated: i) plastic boxes with soil; ii) rolled paper towel with soil; iii) rolled paper towel without soil, and iv) an alternative procedure, using rolled paper towel without soil under cold water. A completely randomized experimental design with eight replications was used and the means were compared by the Tukey test (p = 0.05). To verify the dependence between the alternative test and others single linear correlation was used. All cold test procedures had similar coefficients of variation (CV), highlighting that rolled paper towel with soil and the alternative procedure had the best performance, with an average of 94% and 93% normal seedlings and CV of 3.2% and 3.6%, respectively. The alternative procedure has satisfactory results for estimating soybean seed vigor, yielding consistent results compared to the traditional procedure.

AbstractPercutaneous pulmonary valve implantation is increasingly adopted as an alternative procedure to surgery in dysfunctional homograft, and in patients with “native” or wide right ventricle outflow tract dysfunction. Pre-stenting is mandatory in this category of patients for many reasons, one of which is to create an adequate landing zone for the bioprosthesis. Here we report on a tricky situation that occurred during pre-stenting, and we describe how we successfully overcame it.
