The Correlation Between Abnormal Uterine Artery Flow in the First Trimester and Genetic Thrombophilic Alteration: A Prospective Case-Controlled Pilot…

2020

Introduction. Evaluation of the first trimester uterine artery flow can predict the development of obstetrical complications. A genotype, making women prone to microthrombi. constitutes the main known susceptibility factor for anomalous development of placenta. Our aim was to study whether polymorphisms of 10 genes leading to blood clotting abnormalities are related to abnormal uterine artery blood flow in the first trimester, and may predict placenta-related diseases. Material and methods. In primary analyses we included 19 singleton pregnancies with abnormal blood flow in the uterine arteries during the first trimester of gestation, and 24 matched control with normal flow patterns. All pa…

Clinical Experiences with Clamp Electrodes in Fetal Scalp for Simultaneous pO2 and ECG — Registration

1973

The development of a scalp electrode for continuous measurement of fetal mean tissue-PO2 and simultaneous registration of ECG respectively fetal heart rate has been described previously (1). The electrode mechanics and electronic equipment must be adapted to the various demands of the birth process and the labor room environment. The technical results are not yet refined, when unfavorable conditions prevail, artifacts may be anticipated. A brief review of the proceedings in electrode clamp measurements should be presented.

Said davanti al romanzo: da Mansfield Park al Gattopardo

2013

L'interazione degli studi culturali con la letteratura è stata sempre complessa, sospesa tra sviluppi significativi e pregiudizi fuorvianti. E' possibile verificarlo analizzando alcuni tra gli studi letterari di Edward Said, in particolare quelli in cui il critico si misura con un archetipo del geand romanzo moderno, Mansfield Park di Jane Austen e con una sua celeberrima, tardiva e ingannevole ripresa, Il Gattopardo di Tomasi di Lampedusa. The essay deals with the relationship between Cultural Studies and literature has always been complex, characterized both by meaningful developments and by misleading prejudices; especially analyzing the studies dedicated by Edward Said, to Jane Austen’s…

Framing Migrant Memories: Lampedusa's Fragmented Archives

2022

The small island of Lampedusa, a key destination of the Central Mediterranean Route connecting Africa to Italy, offers a special observatory on the contemporary trans-Mediterranean odyssey of migrants, although often transformed into a “border spectacle.” Upon landing, migrants are stripped of their belongings, as these are impounded by the authorities. Such an act of dispossession is intended to deprive them of their histories, family ties and cultural identity. Photographer Mario Badagliacca has portrayed a selection of these lost and retrieved items in his work Fragments (2013). Each object reveals expectations, fears, desires, endurance, but cannot tell a full story. They are fragments …

A neutralizing antibody against human DNA polymerase epsilon inhibits cellular but not SV40 DNA replication.

1999

The contribution of human DNA polymerase epsilon to nuclear DNA replication was studied. Antibody K18 that specifically inhibits DNA polymerase activity of human DNA polymerase epsilon in vitro significantly inhibits DNA synthesis both when microinjected into nuclei of exponentially growing human fibroblasts and in isolated HeLa cell nuclei. The capability of this neutralizing antibody to inhibit DNA synthesis in cells is comparable to that of monoclonal antibody SJK-132-20 against DNA polymerase alpha. Contrary to the antibody against DNA polymerase alpha, antibody K18 against DNA polymerase epsilon did not inhibit SV40 DNA replication in vitro. These results indicate that DNA polymerase e…

Upes nēģa Lampetra fluviatilis populāciju ģenētiskās daudzveidības izpēte ar mikrosatelītiem

2020

Šis bakalaura darbs ir turpinājums kursa darbam - “Kurzemes upēs sastopamo upes nēģu Lampetra fluviatilis mikrosatelītu genotipēšana”. Šis ir pirmais pētījums Latvijā par upes nēģa ģenētisko daudzveidību un populācijas ģenētisko struktūru Latvijas upēs, pamatojoties uz mikrosatelītu DNS variācijām. Darba mērķis bija novērtēt upes nēģa populācijas ģenētisko daudzveidību Latvijā. Iegūtie dati veicinās zināšanas par upes nēģu ģenētisko struktūru un palīdzēs izstrādāt ieteikumus ģenētisko resursu ilgtspējīgai apsaimniekošanai. No piecām upēm (Saka, Venta, Daugava, Salaca, Gauja) kopā tika ievākti 210 upes nēģa audu paraugi no muguras spurām, no kuriem tika izdalīta DNS. Genotipēšana tika veikta…

Photochemical-chemiliminometric determination of aldicarb in a fully automated multicommutation based flow-assembly

2004

[EN] A sensitive and fully automated method for determination of aldicarb in technical formulations (Temik) and mineral waters is proposed. The automation of the flow-assembly is based on the multicommutation approach, which uses a set of solenoid valves acting as independent switchers. The operating cycle for obtaining a typical analytical transient signal can be easily programmed by means of a home-made software running in the Windows environment. The manifold is provided with a photoreactor consisting of a 150 cm long x 0.8 mm i.d. piece of PTFE tubing coiled around a 20 W low-pressure mercury lamp. The determination of aldicarb is performed on the basis of the iron(III) catalytic minera…

A Fully Automated Assembly Using Solenoid Valves for the Photodegradation and Chemiluminometric Determination of the Herbicide Chlorsulfuron

2005

Abstract This paper presents a new photochemiluminescent system for the determination of chlorsulfuron in water samples. The light from a low‐pressure mercury lamp is used as a clean, reproducible, and inexpensive “reagent” for the derivation of the pesticide, performed in glycine buffer at pH 9.5. Then, the photo‐products from irradiation are oxidized by permanganate in sulfuric acid solution. The oxidation reaction was favored by using high temperatures. A comparative study and discussion about the use of polyphosphoric acid instead of sulfuric acid in the oxidation reaction is also presented. The use of solenoid valves allows for the easy, complete automation of the process with low samp…

High-frequency electrodeless discharge lamps for atomic absorption analysis

2003

Abstract In this paper we present the results of an investigation of high-frequency electrodeless discharge lamps (HFEDLs), containing Cd, Zn, Hg, As, Te, Se, Pb, Sn, Tl and Bi, developed in our laboratories as light sources for atomic absorption spectrometry (AAS). Important physical processes in the lamps are discussed. Essential characteristics of HFEDLs for AAS, such as intensity, stability and operating life are considered. The intensities and detection limits are compared with the corresponding characteristics of hollow cathode lamps. The temporal behavior of an As HFEDL is compared with that of a commercially available electrodeless discharge lamp. Detection limits in graphite furnac…
