Babesia bigemina Apical Membrane Antigen-1: features of the gene and predictive information of the protein from Italian strains
2010
Babesia bigemina is a tick-borne haemoparasite affecting cattle in different parts of the world. One of the few antigens characterized in this species codifies for the Apical Membrane Antigen 1 (AMA-1), a transmembrane protein recently identified. In this work, we characterized the ama-1 gene from four Italian B.bigemina strains, two obtained from Ragusa, Sicily (ITA1 and ITA3), one obtained from Benevento, Campania (ITA2) and one coming from Perugia, Umbria (ITA4). Italian sequences were compared to the Australian strain, whose sequence is available in the Sanger Institute web site, and to some strains coming from different parts of the world. This study provides useful information on the …

Development of fluorogenic probe-based PCR assays for the detection and quantification of bovine piroplasmids.
2009
This paper reports two new quantitative PCR (qPCR) assays, developed in an attempt to improve the detection of bovine piroplasmids. The first of these techniques is a duplex TaqMan assay for the simultaneous diagnosis of Babesia bovis and B. bigemina. This technique is ideal for use in South America where bovids harbour no theilerids. The second technique, which is suitable for the diagnosis of both babesiosis and theileriosis worldwide, involves fluorescence resonance energy transfer (FRET) probes. In FRET assays, Babesia bovis, B. divergens, Babesia sp. (B. major or B. bigemina), Theileria annae and Theileria sp. were all identifiable based on the melting temperatures of their amplified f…
Gas—liquid chromatographic analyses
1984
Abstract The gas chromatography (GC) of n -alkyl acetates (CH 3 COOR), chloroacetates (CH 2 ClCOOR), dichloroacetates (CHCl 2 COOR) and trichloroacetates (CCl 3 COOR), where the alcohol chain length (R) varied between 1 and 8, and certain of their monochlorinated derivatives, 176 compounds altogether, has been studied on SE-30 and OV-351 glass capillary columns under the same operating conditions. The isomeric monochlorinated esters are eluted in direct order from the 1- chloro to the ω-chloro isomer, the separation of the isomers being complete on OV- 351. On SE-30, however, the peaks of the 6- and 7-chlorooctyl esters are partly overlapped. The separation of the mixtures of odd- and e…
Resonating valence bond quantum Monte Carlo: Application to the ozone molecule
2015
We study the potential energy surface of the ozone molecule by means of Quantum Monte Carlo simulations based on the resonating valence bond concept. The trial wave function consists of an antisymmetrized geminal power arranged in a single-determinant that is multiplied by a Jastrow correlation factor. Whereas the determinantal part incorporates static correlation effects, the augmented real-space correlation factor accounts for the dynamics electron correlation. The accuracy of this approach is demonstrated by computing the potential energy surface for the ozone molecule in three vibrational states: symmetric, asymmetric and scissoring. We find that the employed wave function provides a de…
Changing paradigm in mild traumatic brain injury research
2016
Traumatic brain injury (TBI) is a major cause of death and disability among young adults. Recent data show that TBI affects about 1.7 million people annually in the United States (Faul and Coronado, 2015). After TBI, the primary injury produces almost irreparable brain damage. However, recent experimental studies have shown evidence for dynamic brain repair following TBI because endogenous progenitor cells may play regenerative roles in response to injuries (McGinn and Povlishock, 2015). In surviving patients, what plays a critical role in the clinical prognosis is the subsequent secondary injury; without effective treat- ment, cascades that include glutamatergic excitotoxicity and calcium …
