The use of spectral fluorescence methods to detect changes in the phytoplankton community

1998

In vivo fluorescence methods are efficient tools for studying the seasonal and spatial dynamics of phytoplankton. Traditionally the measurements are made using single excitation-emission wavelength combination. During a cruise in the Gulf of Riga (Baltic Sea) we supplemented this technique by measuring the spectral fluorescence signal (SFS) and fixed wavelength fluorescence intensities at the excitation maxima of main accessory pigments. These methods allowed the rapid collection of quantitative fluorescence data and chemotaxonomic diagnostics of the phytoplankton community. The chlorophyll a-specific fluorescence intensities (R) and the spectral fluorescence fingerprints were analysed toge…

In the ovary of Ciona intestinalis (Type A), immune-related galectin and phenoloxidase genes are differentially expressed by the follicle accessory c…

2017

Abstract Riboprobes (in situ hybridization) and antibodies (immunohistochemistry), previously used to show the upregulation of Ciona intestinalis (Type A) galectins (CiLgals-a, CiLgals-b) and phenoloxidase (CinPO2) immune-related genes, were tested on histological sections of the ovary. The ovarian follicles are composed of oocytes encased by follicular cells (FCs) and test cells (TCs). Results show the transcription upregulation of both CiLgals and CinPO2 genes in the vitellogenic FCs, conversely distinct cytolocalization of the proteins are shown. At vitellogenic stage, the CiLgals are localized in the FCs, in the oocyte cytoplasm, and close to the germinal vesicle (GV), whereas the CinPO…

Prevalence of human papilloma virus infection in patients with male accessory gland infection

2015

The frequency of human papillomavirus (HPV) infection in the semen of patients with male accessory gland infection (MAGI) was evaluated. One hundred infertile patients with MAGI were classified into group A: patients with an inflammatory MAGI (n = 48) and group B: patients with a microbial form (n = 52). Healthy age-matched fertile men (34.0 ± 4.0 years) made up the control group (n = 20). Amplification of HPV DNA was carried out by HPV-HS Bio nested polymerase chain reaction for the detection of HPV DNA sequences within the L1 ORF. Ten patients in group A (20.8%) and 15 patients in group B (28.8%) had a HPV infection; two controls (10.0%) had HPV infection. Patients with MAGI had a signifi…

A longitudinal single-center cohort study on the prevalence and risk of accessory saphenous vein reflux after radiofrequency segmental thermal ablati…

2015

Objective Endothermal ablation has become a commonly used technology for occlusion of refluxing great saphenous veins (GSVs). However, the risk for primarily untreated accessory saphenous veins (ASVs) to develop reflux during follow-up has not yet been defined. Here, the prevalence and risk of ASV reflux is explored. Methods During a prospective multicenter cohort study on radiofrequency segmental thermal ablation of refluxing GSVs, the presence and reflux status of ASVs were monitored in 93 legs in a single center. Control examinations were performed after 1 week and at 12, 24, 36, and 48 months. Life-table and multiple regression analyses were used to describe frequency and risk factors f…

L'Autorità garante della concorrenza e del mercato ei prgrammi di clemenza

2010

A distanza di tre anni dall'introduzione dei programmi di clemenza nella legge antitrust italiana, si impone una riflessione sui problemi aperti dalla loro adozione e applicazione. Il contributo li esamina, comparando il sistema italiano con quello comunitario e con gli altri sistemi vigenti nell'ambito dell'ECN. Evidenzia, quindi, alcuni aspetti critici della disciplina italiana, relativi all'accesso dei terzi alle dichiarazioni confessorie e alla documentazione allegata.

Segmental dyskinesia in Wolff–Parkinson–White syndrome: A possible cause of dilatative cardiomyopathy

2006

Wolff-Parkinson-White (WPW) is a syndrome characterized by the presence of an accessory pathway that skipping A-V node may lead the electrical stimulus from the atrium directly to the ventricle. Some studies reported the finding of myocardial dyskinesia in the segments precociously activated by the accessory pathway, at echocardiogram and at nuclear cardiac study. Soria et al. reported, in 1985, an increased incidence of dilative cardiomyopathy in patients with WPW. The pathophysiological pathway that leads to ventricular dilation may be due to the increase of end-diastolic pressure secondary to a tachycardia-induced cardiomyopathy. Tachycardia-induced cardiomyopathy is usually secondary to…

Energy transfer and pigment composition in three chlorophyll b-containing light-harvesting complexes isolated from Mantoniella squamata (Prasinophyce…

1986

Light-harvesting Chl a/b protein complexes were isolated from the higher plant Sinapis alba, the green alga Chlorella fusca, and the prasinophycean alga Mantoniella squamata by mild gel electrophoresis. The energy transfer from chlorophyll b and the accessory xanthophyll was measured by means of fluoresence spectroscopy at 77 K. The pigment composition of the isolated antenna complexes was determined by high performance liquid chromatography in order to calculate the number of light absorbing molecules per chlorophyll a in the different light-harvesting complexes. These results were complemented by the quantitation of the pigments in total thylakoids as well as in the different electrophore…
