Prenatal diagnosis and postnatal follow-up of congenitally corrected transposition of the great arteries and recurrent supraventricular tachycardia
The prenatal sonographic diagnosis of congenitally corrected transposition of the great arteries
(ccTGA), a rare form of congenital heart disease is very difficult. A24-year-old woman was referred
to our center at 28 weeks’ gestation because of suspected fetal cardiac anomalies. This article reports a case
of ccTGA with supraventricular tachycardia, ventricular septal defect, pulmonary valve stenosis,
tricuspid valvar displacement and moderate tricuspid regurgitation during her pregnancy. The
combined presence of SVT and ccTGA are occasionally present in the literature.peer-reviewe
A Hand that Holds a Machete: Race and the Representation of the Displaced in Jacques Audiard’s Dheepan
This article explores the norms, spaces, positions and conditions of visibility for non-white refugees and migrants as well as white non-refugee characters in Dheepan (Jacques Audiard, 2015), a film which received much praise for its humane representation of refugees and won the Palme d’Or at Cannes. Through a close analysis, this article aims to demonstrate number of recurring elements that are often determined by imaginations of race in European film productions that represent refugees and migrants. Analysing the film, along with its production and reception, this study shows how European whiteness remains the invisible norm of non-violence, while the non-whiteness of the displaced remains outside this norm and is visibly and unquestionably locked into acts, positions, objects (holding a machete) and spaces of violence and crisis: the jungle, the refugee camp, the banlieue, the darkness of a cellar
Regression based polynomial chaos expansion for crop phenology estimation coupled with polsar imagery
Crop phenology monitoring using Synthetic Aperture Radar(SAR) data is gaining popularity within the remote sensing community due to SAR’s all weather and large coverage imaging capability. This paper introduces a polynomial chaos expansion (PCE) based regression algorithm to retrieve BBCH scale of crops, which identifies the phenology of crops in a standardized system. The impact and applicability of the proposed methodology is successfully illustrated using the TerraSAR-X dual-pol imagery that was acquired over the cultivation period of paddy-rice fields located in Turkey. To assess the applicability of the methodology, root mean square and correlation analysis were performed under different amount of training data and number of inputs

Distinct roles of exogenous opioid agonists and endogenous opioid peptides in the peripheral control of neuropathy-triggered heat pain
Neuropathic pain often results from peripheral nerve damage, which can involve
immune response. Local leukocyte-derived opioid peptides or exogenous opioid
agonists inhibit neuropathy-induced mechanical hypersensitivity in animal
models. Since neuropathic pain can also be augmented by heat, in this study we
investigated the role of opioids in the modulation of neuropathy-evoked heat
hypersensitivity. We used a chronic constriction injury of the sciatic nerve
in wild-type and opioid peptide-knockout mice, and tested opioid effects in
heat and mechanical hypersensitivity using Hargreaves and von Frey tests,
respectively. We found that although perineural exogenous opioid agonists,
including peptidergic ligands, were effective, the endogenous opioid peptides
β-endorphin, Met-enkephalin and dynorphin A did not alleviate heat
hypersensitivity. Specifically, corticotropin-releasing factor, an agent
triggering opioid peptide secretion from leukocytes, applied perineurally did
not attenuate heat hypersensitivity in wild-type mice. Exogenous opioids, also
shown to release opioid peptides via activation of leukocyte opioid receptors,
were equally analgesic in wild-type and opioid peptide-knockout mice,
indicating that endogenous opioids do not contribute to exogenous opioid
analgesia in heat hypersensitivity. Furthermore, exogenously applied opioid
peptides were ineffective as well. Conversely, opioid peptides relieved
mechanical hypersensitivity. Thus, both opioid type and sensory modality may
determine the outcome of neuropathic pain treatment
Prevalence and distribution of the fabella: a radiographic study in Turkish subjects
Background: The purpose of this study is to examine the plain knee radiographs in Turkish subjects in order to determine the prevalence of the fabella and analyse the differences between age, gender, laterality and its symmetry pattern.
Materials and methods: Bilateral antero-posterior and lateral knee radiographs of 500 patients (250 male and 250 female subjects, 1000 knee radiographs) were randomly selected from the clinical database and retrospectively evaluated. Data on patient age, gender, and knee laterality (right–left) were evaluated from hospital records. The differences between the sesamoid bones at a particular location and the side, sex and age groups were analysed.
Results: The overall prevalence of the fabella (unilateral or bilateral) was 22.8% (114 subjects). The fabella was present unilaterally in 38 (7.6%) subjects, while it was present bilaterally in 76 (15.2%) subjects. The prevalence of the fabella was similar between the body sides. The prevalence of the fabella was also similar between genders (unilateral or bilateral cases) and age groups.
Conclusions: We examined the prevalence, symmetry pattern, age and gender differences in Turkish population. It is the first study performed on Turkish population with the largest sample in current literature. Prevalence of fabella is found to be 22.8% which is quite similar with other Caucasian ethnic populations
