Here, a quantitative magnetic depth profile across the planar interfaces in BiFeO3 /La0.7 Sr0.3 MnO3 (BFO/LSMO) superlattices using polarized neutron reflectometry is obtained. An enhanced magnetization of 1.83 ± 0.16 μB /Fe in BFO layers is observed when they are interleaved between two manganite layers. The enhanced magnetic order in BFO persists up to 200 K. The depth dependence of magnetic moments in BFO/LSMO superlattices as a function of the BFO layer thickness is also explored. The results show the enhanced net magnetic moment in BFO from the LSMO/BFO interface extends 3-4 unit cells into BFO...

INTRODUCTION: Fronto-metaphyseal dysplasia (FMD), also called Gorlin-Cohen syndrome, is a rare syndrome initially described in 1969 by Gorlin and Cohen. Patients present skeletal dysplasia, craniofacial malformations and digit abnormalities. Craniofacial phenotype of FMD is characterized by supraorbital hyperostosis, hypertelorism, down-slanting palpebral fissures, broad nasal bridge and micrognathia. Here, we report the first adult case of craniofacial reconstruction with frontal cranioplasty in a patient with FMD...

Gorlin-Goltz syndrome (GGS) is a rare genetic syndrome with variable expressivity and autosomal dominant inheritance. The major features of GGS include numerous basal cell carcinomas (BCCs), keratocysts of the jaw, palmar/plantar pits and calcification of the falx cerebri. Authors report the case of a 51-year-old male with a 19-year history of GGS and multiple BCCs of the head and neck. He presented with a large ulcerating lesion on the right side of his face involving cutaneous, subcutaneous and muscular tissues of the temporal and orbital region...

In situ splitting of rib bone graft was conducted in 22 patients for the repair of orbital fracture with no other complicating fractures. A bone graft was harvested from the sixth or seventh rib in the right side. The repair of the orbital floor and medial wall was successful in all the cases. Ten patients had bone grafting to the orbital floor, eight had it done onto medial wall, and 4 onto both floor and wall after reduction. The mean length of in situ rib bone graft was 40.9 mm (range, 20-70 mm), the mean width of these was 14...

BACKGROUND: Poor prognosis of sinonasal cancers (SNC) is usually due to the non-specific symptoms leading to late diagnosis with locally advanced disease. However, previous prognostic studies were often based on heterogeneous cohorts because of the scarcity of SNC. With squamous cell carcinoma being the main histological subgroup, the study aimed to perform a prognostic analysis on sinonasal squamous cell carcinoma (SNSCC) particularly, and to evaluate the oncological results of a multimodal therapy...

Conventional dental implants have been reported for nasal and orbital regions but due to limited thickness of calvarium they are not used in mastoid region. Onlay bone grafting in skull concomitant with implants is a predictable method and experimental animal studies confirm it. Parietal bone and lateral mandibular ramus are suggested source of bone grafts and dental implants with 7 mm length can be used safely. Increased fixture length may lead to increase survival in long term.

A 36-year-old man presented because of nasal obstruction, rhinorrhea, and postnasal drip. The patient had undergone reconstruction of a blow-out fracture of the orbital floor 12 years before and had sinusitis that likely had resulted from implant migration into the maxillary sinus. The inflammation was successfully resolved, and the implant was removed through a minimally invasive endoscopic sinus surgery technique. On pathologic examination, an organizing hematoma was identified as the cause of the lesion...

We describe a female patient who presented with watering followed by swelling in the left infraorbital area of 5 years duration. She had previously been prescribed topical antibiotics on several occasions with no improvement. On pressure over the swelling, there was blood-tinged discharge from the left eye and nostril. Magnetic resonance imaging revealed an enhancing, well-defined mass lesion in the inferomedial aspect of the left orbit, likely of nasolacrimal origin. Computed tomography dacryocystogram with three-dimensional reconstruction showed a well-circumscribed mass with an irregular surface, originating from the lacrimal sac...

Chronic maxillary atelectasis (CMA) and silent sinus syndrome (SSS) are rare clinical entities characterized by an implosion of the maxillary sinus that may or may not be associated with sinonasal symptoms, and are complicated by ipsilateral enophthalmos. The objective of this article is to discuss the definitions, physiopathology, clinical and radiographic characteristics, and surgical management of these entities. We retrospectively reviewed 18 patients (7 women, 11 men, aged 12-70 years) diagnosed and treated in the ear, nose, and throat departments of four Belgian teaching hospitals between 2000 and 2015...

Multiferroic hybrid structures PbZr0.2Ti0.8O3 (PZT)/La0.7Sr0.3MnO3 (LSMO) and PZT/MgO/LSMO were epitaxially deposited on (001) Nb:SrTiO3 crystals. Crystallinity and ferroelectric domain structures were investigated for the PZT/LSMO heterostructure. Interestingly, relatively high non-volatile magnetoelectric coupling effects were observed in both heterostructures at room temperature. The change of chemical valence for Mn and Ti at the PZT/MgO/LSMO interface may play a dominant role rather than external strain or orbital reconstruction, which lead to a large modulation of the magnetization...

A conceptual difficulty in formulating the density-functional theory of the fractional quantum Hall effect is that while in the standard approach the Kohn-Sham orbitals are either fully occupied or unoccupied, the physics of the fractional quantum Hall effect calls for fractionally occupied Kohn-Sham orbitals. This has necessitated averaging over an ensemble of Slater determinants to obtain meaningful results. We develop an alternative approach in which we express and minimize the grand canonical potential in terms of the composite fermion variables...

BACKGROUND: Anatomical knowledge of the facial vasculature is crucial for successful plastic, reconstructive, and minimally invasive procedures of the face. Whereas the majority of previous investigations focused on facial arteries, the precise course, variability, and relationship with adjacent structures of the facial vein have been widely neglected. METHODS: Seventy-two fresh frozen human cephalic cadavers (32 male and 40 female cadavers; mean age, 75.2 ± 10...
