Design of a Cavity for the High-Power Radio-Frequency Quadrupole Coupler Test for the ANTHEM Project.

The ANTHEM (Advanced Technologies for Human-centered Medicine) Radio-Frequency Quadrupole (RFQ) will employ eight coaxial power couplers, which will be magnetically coupled to the device through a loop antenna. The coupler design can support up to 140 kW in continuous wave operation. This paper presents the design of the cavity used for high-power testing, with the primary objectives of both optimizing the coupling between the couplers and ensuring operations at the designated operating frequency.

Population Genomic History of the Endangered Anatolian and Cyprian Mouflons in Relation to Worldwide Wild, Feral, and Domestic Sheep Lineages.

Once widespread in their homelands, the Anatolian mouflon (Ovis gmelini anatolica) and the Cyprian mouflon (Ovis gmelini ophion) were driven to near extinction during the 20th century and are currently listed as endangered populations by the International Union for Conservation of Nature. While the exact origins of these lineages remain unclear, they have been suggested to be close relatives of domestic sheep or remnants of proto-domestic sheep. Here, we study whole genome sequences of n = 5 Anatolian mouflons and n = 10 Cyprian mouflons in terms of population history and diversity, comparing them with eight other extant sheep lineages.

Phenotype transition from wild mouflon to domestic sheep.

The domestication of animals started around 12,000 years ago in the Near East region. This "endless process" is characterized by the gradual accumulation of changes that progressively marked the genetic, phenotypic and physiological differences between wild and domesticated species. The main distinctive phenotypic characteristics are not all directly attributable to the human-mediated selection of more productive traits.

Adaptive Response to Gillnets Bycatch in a North Sardinia Mediterranean Shag () Population.

Mediterranean Shag () is a seabird endemic to the Mediterranean and Black Seas, recently included in the IUCN list of threatened Species. Most of the reproductive colonies are hosted in Sardinia and surrounding islets. Bycatch in fishing nets is one of the most significant threats for this population.

range verification analysis with in-beam PET data for patients treated with proton therapy at CNAO.

Morphological changes that may arise through a treatment course are probably one of the most significant sources of range uncertainty in proton therapy. Non-invasive treatment monitoring is useful to increase treatment quality. The INSIDE in-beam Positron Emission Tomography (PET) scanner performs range monitoring in proton and carbon therapy treatments at the National Center of Oncological Hadrontherapy (CNAO).

Localization of anatomical changes in patients during proton therapy with in-beam PET monitoring: A voxel-based morphometry approach exploiting Monte Carlo simulations.

Purpose: In-beam positron emission tomography (PET) is one of the modalities that can be used for in vivo noninvasive treatment monitoring in proton therapy. Although PET monitoring has been frequently applied for this purpose, there is still no straightforward method to translate the information obtained from the PET images into easy-to-interpret information for clinical personnel. The purpose of this work is to propose a statistical method for analyzing in-beam PET monitoring images that can be used to locate, quantify, and visualize regions with possible morphological changes occurring over the course of treatment.

Anthropogenic Drivers Leading to Population Decline and Genetic Preservation of the Eurasian Griffon Vulture ().

Human activities are having increasingly devastating effects on the health of marine and terrestrial ecosystems. Studying the adaptive responses of animal species to changes in their habitat can be useful in mitigating this impact. Vultures represent one of the most virtuous examples of adaptation to human-induced environmental changes.

Genetic characterization and implications for conservation of the last autochthonous Mouflon population in Europe.

Population genetic studies provide accurate information on population structure, connectivity, and hybridization. These are key elements to identify units for conservation and define wildlife management strategies aimed to maintain and restore biodiversity. The Mediterranean island of Sardinia hosts one of the last autochthonous mouflon populations, descending from the wild Neolithic ancestor.

First mtDNA Sequences and Body Measurements for from the Mediterranean Island of Cyprus.

Invasive species are the primary driver of island taxa extinctions and, among them, those belonging to the genus are considered as the most damaging. The presence of black rat () on Cyprus has long been established, while that of brown rat () is dubious. This study is the first to provide molecular and morphological data to document the occurrence of in the island of Cyprus.

Mitochondrial D-loop Sequence Variability in Three Native Insular Griffon Vulture () Populations from the Mediterranean Basin.

The islands of Sardinia, Crete, and Cyprus are hosting the last native insular griffon populations in the Mediterranean basin. Their states have been evaluated from "vulnerable" to "critically endangered". The sequence analysis of molecular markers, particularly the mtDNA D-loop region, provides useful information in studying the evolution of closely related taxa and the conservation of endangered species.

Identification of an ancestral haplotype in the mitochondrial phylogeny of the ovine haplogroup B.

Background: European mouflon () has been reintroduced in mainland Europe since the 18th-century sourcing from the Sardinian and Corsican autochthonous mouflon populations. The European mouflon is currently considered the feral descendent of the Asian mouflon (), and the result of first wave of sheep domestication occurred 11,000 years ago in the Fertile Crescent, and brought to Corsica and Sardinia ca. 6,000 years ago, where they still live as autochthonous populations.

Structural features of cross-sectional wing bones in the griffon vulture (Gyps fulvus) as a prediction of flight style.

Flight is an energetically costly form of transport imparting biomechanical stress that acts upon the wing bones. Previous studies have suggested that the cross-sectional and microstructural features of wing bones may be adapted to resist biomechanical loads. During flight, however, each wing bone potentially experiences a unique loading regime.

Effects of melatonin administration on seminal plasma metabolites and sperm fertilization competence during the non-reproductive season in ram.

The purpose of this study was to investigate the effects of ram melatonin treatment on the sperm quality and metabolite composition of the seminal plasma in the non-breeding season. Four mature rams were treated with 54 mg melatonin in March subcutaneous implants and four untreated rams served as control. At 0, 30, 90 and 120 days semen samples were collected and sperm, separated from seminal plasma, was evaluated for its capacity to fertilize and produce embryos in vitro.

Genomic signatures of adaptive introgression from European mouflon into domestic sheep.

Mouflon (Ovis aries musimon) became extinct from mainland Europe after the Neolithic, but remnant populations from the Mediterranean islands of Corsica and Sardinia have been used for reintroductions across Europe since the 19-century. Mouflon x sheep hybrids are larger-bodied than mouflon, potentially showing increased male reproductive success, but little is known about genomic levels of admixture, or about the adaptive significance of introgression between resident mouflon and local sheep breeds. Here we analysed Ovine medium-density SNP array genotypes of 92 mouflon from six geographic regions, along with data from 330 individuals of 16 domestic sheep breeds.

Molecular Characterization of β-Thalassemia Mutations in Central Vietnam.

The molecular basis of β-thalassemia (β-thal) mutations in North and in South Vietnam have been described during the past 15 years, whereas limited data were available concerning the central area of the country. In this study, we describe the molecular characterization and frequency of β-globin gene mutations in the Thua Thien Hue Province of Central Vietnam as the result of a first survey conducted in 22 transfusion-dependent patients, and four unrelated heterozygotes. Nine different known mutations were identified (seven of the β and two of the β type) in a total of 48 chromosomes.

Biochemical and Molecular Analysis of the Hb Lepore Boston Washington in a Syrian Homozygous Child.

Hemoglobin (Hb) Lepore is composed of two normal chains and two fusion globins that arise from unequal crossover events between the - and -globin genes. The Hb Lepore is widespread all over the world and in many ethnic groups. It includes some of the few clinically significant Hb variants that are associated with a -thalassemia phenotype.

A Novel -72 (T→A) -Promoter Mutation Causing Slightly Elevated HbA in a Vietnamese Heterozygote.

We report a novel -thalassemia mutation found in a Vietnamese family. The molecular defect T→A lies at -72 of the -globin gene promoter, within the conserved CCAAT box. The index case was a 5-year-old child having red blood cells indices close to normal and slightly increased level of HbA (3.

The New -474(C→T) Substitution Discovered in the HBG2 Promoter of a Sardinian δβ-Thalassemia Carrier.

During a screening for hemoglobinopathies, we found a carrier of the Sardinian δβ-thalassemia condition. The proband's hematology and hemoglobin (Hb) profile agreed with those of the other carriers previously identified during our diagnostic program except for the fetal Hb (HbF) composition, which consisted of both α2Aγ2 and α2Gγ2 instead of nearly 100% α2Aγ2. In order to explain the unusual γ-chain ratio, sequencing of the Gγ promoter was carried out and revealed two nucleotide substitutions in cis: C→T at position -474 and A→G at position -309 from the Cap site.

The First Mitogenome of the Cyprus Mouflon (Ovis gmelini ophion): New Insights into the Phylogeny of the Genus Ovis.

Sheep are thought to have been one of the first livestock to be domesticated in the Near East, thus playing an important role in human history. The current whole mitochondrial genome phylogeny for the genus Ovis is based on: the five main domestic haplogroups occurring among sheep (O. aries), along with molecular data from two wild European mouflons, three urials, and one argali.

Hb F-Avellino [(G)γ41(C7)Phe → Leu; HBG2: c.124 T > C]: A New Hemoglobin Variant Observed In A Healthy Newborn.

Here we describe Hb F-Avellino [(G)γ41(C7)Phe → Leu; HBG2: c.124 T > C], a new hemoglobin (Hb) variant observed in a healthy newborn. The proband's hemolysate was found to be mildly unstable by the isopropanol test.

A Novel Heme Pocket Hemoglobin Variant Associated with Normal Hematology: Hb Zara or α91(FG3)Leu→Ile (α2) (HBA2: c.274C > A).

We report a new hemoglobin (Hb) variant on the HBA2 gene, Hb Zara [α91(FG3)Leu→Ile (α2); HBA2: c.274C > A], which was found in a Caucasian man from Croatia. It was observed by routine cation exchange chromatography as an abnormal 21.

A new unstable variant of the fetal hemoglobin HBG2 gene: Hb F-Turritana [(G) γ64(E8)Gly→Asp, HBG2:c.194G>A] found in cis to the Hb F-Sardinia gene [(A) γ(E19)Ile→Thr, HBG1:c.227T>C].

A new variant of the fetal hemoglobin (Hb) was observed in a newborn baby subjected to phototherapy due to jaundice, by means of electrophoretic and chromatographic techniques. The variant Hb resulted unstable by the isopropanol stability test. After HBG2 gene sequencing, the G to A transversion at codon 64, position eight of the E helix, was found, which corresponds to the Asp for Gly amino acid substitution.

Haplotype affinities resolve a major component of goat (Capra hircus) MtDNA D-loop diversity and reveal specific features of the Sardinian stock.

Goat mtDNA haplogroup A is a poorly resolved lineage absorbing most of the overall diversity and is found in locations as distant as Eastern Asia and Southern Africa. Its phylogenetic dissection would cast light on an important portion of the spread of goat breeding. The aims of this work were 1) to provide an operational definition of meaningful mtDNA units within haplogroup A, 2) to investigate the mechanisms underlying the maintenance of diversity by considering the modes of selection operated by breeders and 3) to identify the peculiarities of Sardinian mtDNA types.

Functional properties of the newly observed (G)γ-chain fetal hemoglobin variant Hb F-Monserrato-Sassari (HBG2:c.280T>C) or [(G)γ93 (F9) Cys→Arg].

Background: HbF-Monserrato-Sassari is a newly discovered abnormal fetal hemoglobin observed in an apparently normal newborn baby during a hemoglobinopathies survey at birth in North Sardinian population.

Methods: Electrophoretic analysis of the cord blood lysate evidenced for an abnormal tetramer due to a mutated fetal globin chain. Electrospray ionisation-mass spectrometry and gene sequencing were used to identify the mutation.

Two abnormal fetal hemoglobins found in the Sardinian population: the new Hb F-Osilo [(A)gamma119(GH2)Gly-->Ser, GGC > AGC] and Hb F-Paulinia [(G)gamma80(EF4)Asp-->Tyr, GAT > TAT] already described in the Brazilian population.

Two healthy newborns, heterozygous for two different gamma-globin chain mutations, were observed during an electrophoretic screening for hemoglobinopathies in Sassari, North Sardinia (Italy). The variants were characterized by reversed phase high performance liquid chromatography (HPLC) and sequencing of amplified gamma-globin genes. One of the two abnormalities was a novel (A)gammachain variant and the tetramer was named Hb F-Osilo [(A)gamma119(GH2)Gly-->Ser].
