PET Molecular Targets and Near-Infrared Fluorescence Imaging of Atherosclerosis
PURPOSE OF REVIEW: With this review, we aim to summarize the role of positron emission tomography (PET) and near-infrared fluorescence imaging (NIRF) in the detection of atherosclerosis. RECENT FINDINGS: (18)F-FDG is an established measure of increased macrophage activity. However, due to its low specificity, new radiotracers have emerged for more specific detection of vascular inflammation and other high-risk plaque features such as microcalcification and neovascularization. Novel NIRF probes are engineered to sense endothelial damage as an early sign of plaque erosion as well as oxidized low-density lipoprotein (oxLDL) as a prime target for atherosclerosis. Integrated NIRF/OCT (optical coherence tomography) catheters enable to detect stent-associated microthrombi. Novel radiotracers can improve specificity of PET for imaging atherosclerosis. Advanced NIRF probes show promise for future application in human. Intravascular NIRF might play a prominent role in the detection of stent-induced vascular injury
Diet and food strategies in a southern al-Andalusian urban environment during Caliphal period, ecija, Sevilla
The Iberian medieval period is unique in European history due to the widespread socio-cultural changes that took place after the
arrival of Arabs, Berbers and Islam in 711 AD. Recently, isotopic research has been insightful on dietary shifts, status, resource
availability and the impact of environment. However, there is no published isotopic research exploring these factors in southern
Iberian populations, and as the history of this area differs to the northern regions, this leaves a significant lacuna in our
knowledge. This research fills this gap via isotopic analysis of human (n = 66) and faunal (n = 13) samples from the 9th to the
13th century Écija, a town renowned for high temperatures and salinity. Stable carbon (δ13C) and nitrogen (δ15N) isotopes were
assessed from rib collagen, while carbon (δ13C) values were derived from enamel apatite. Human diet is consistent with C3 plant
consumption with a very minor contribution of C4 plants, an interesting feature considering the suitability of Écija to C4 cereal
production. δ15N values vary among adults, which may suggest variable animal protein consumption or isotopic variation within
animal species due to differences in foddering. Consideration of δ13C collagen and apatite values together may indicate sugarcane
consumption, while moderate δ15N values do not suggest a strong aridity or salinity effect. Comparison with other Iberian groups
shows similarities relating to time and location rather than by religion, although more multi-isotopic studies combined with
zooarchaeology and botany may reveal subtle differences unobservable in carbon and nitrogen collagen studies alone.OLC is funded by Plan Galego I2C mod.B (ED481D 2017/014).

Durendal, translated: Islamic object genealogies in the chansons de geste
The transfer of Saracen arms into Frankish ownership is a leitmotif of
many chansons de geste, but one whose significance for translatio imperii has yet to be
elucidated. In this essay, I focus on the Chanson d’Aspremont, a twelfth-century epic
set in Calabria that narrates the pre-history of Durendal, Roland’s sword of Song of
Roland fame, as an object inherited by Roland from its former royal Muslim owner.
Drawing on cultural history and a number of object-translation models derived from
material and spolia studies, I read the sword’s symbolic transfer as evidence of Norman
desire for and appropriation of former Fatimid imperium in Sicily
Toledean testimony: Reconquista, architectural Convivencia and the man from La Mancha
This is how the discovery occurred. One day I was in the Alcana at Toledo, when a lad came to sell some parchments and old papers to a silk merchant. Now as I have a taste for reading even torn papers lying in the streets, I was impelled by my natural inclination to take up one of the parchment books the lad was selling, and saw in it characters which I recognized as Arabic. But though I could recognize them I could not read them. Don Quixote de la Mancha-(Graf, 1999, p. 77)
