Abstract

Multimodal imaging and spectroscopy like concurrent scanning transmission X-ray microscopy (STXM) and X-ray fluorescence (XRF) are highly desirable as they allow retrieving complementary information. This paper reports on the design, development, integration and field testing of a novel in situ atomic force microscopy (AFM) instrument for operation under high vacuum in a synchrotron soft X-ray microscopy STXM–XRF end-station. A combination of μXRF and AFM is demonstrated for the first time in the soft X-ray regime, with an outlook for the full XRF–STXM–AFM combination. [ABSTRACT FROM AUTHOR]

Abstract

Spontaneous canalith jam is an uncommon form of benign paroxysmal positional vertigo mimicking acute vestibular neuritis. We described for the first time a spontaneous horizontal semicircular canalith jam associated with a typical canalolithiasis involving contralateral posterior semicircular canal (PSC), illustrating how the latter condition modified direction-fixed nystagmus during head movements. An 81-year-old woman with persistent vertigo referred to our center. Video-Frenzel examination showed horizontal direction-fixed right-beating nystagmus in primary gaze position, inhibited by visual fixation. She exhibited corrective saccades after leftward head impulses. Chin-to-chest positioning at the head-pitch test did not modify spontaneous nystagmus, whereas slight torsional components with the top pole of the eye beating toward the right ear appeared in backward head-bending, resulting in mixed horizontal-torsional nystagmus. At supine positioning tests, direction-fixed nystagmus turned into direction-changing geotropic horizontal nystagmus, which was stronger on the left side, while overlapping upbeat nystagmus with torsional right-beating components appeared on the right. Primary clinical findings were consistent with a left horizontal semicircular canalith jam, inducing a persistent utriculofugal cupular displacement, combined with a typical right-sided PSC-canalolithiasis. Once canalith jam crumbled, resulting in a non-ampullary arm canalolithiasis of the horizontal semicircular canal, both involved canals were freed by debris with appropriate repositioning procedures.

Abstract

In spite of the constant technological improvements in the field of detector development, X-ray fluorescence (XRF) in the soft X-ray regime remains a challenge. The low intrinsic fluorescence yield for energies below 2 keV indeed renders the applicability of low-energy XRF still difficult. Here, we report on a new multi-element multi-tile detection system currently under development, designed to be integrated into a soft X-ray microscopy end station. The system will be installed at the TwinMic beamline of Elettra synchrotron (Trieste, Italy) in order to increase the detected count rate by up to an order of magnitude. The new architecture is very versatile and can be adapted to any XRF experimental setup. Even though the first results of the previous version of such a multi-element system were encouraging, several issues still needed to be addressed. The system described here represents a further step in the detector evolution. It is based on four trapezoidal-shaped monolithic silicon drift detector tiles (matrices) with six hexagonal elements each equipped with a custom ultra-low noise application-specific integrated circuit readout. The whole signal processing chain has been improved leading to an overall increase in performances, namely, in terms of energy resolution and acquisition rates. The design and development of this new detection system will be described, and recent results obtained at the TwinMic beamline at Elettra will be presented. Future perspectives and improvements will also be discussed.

Abstract

In synchrotron facilities, imaging techniques are on high demand from the scientific community. Those related to X-ray microscopy are among the most prominent ones. Such techniques include scanning transmission x-ray microscopy (STXM), full-field transmission x-ray microscopy (TXM), and coherent diffraction imaging (CDI) which have a wide spectrum of applications ranging from clinical and biomedical sciences to nanotechnology and cultural heritage. Their advancement is achieved through specialisation and focused studies, often requiring dedicated beamline end-stations. On the other hand, scientific applications benefit from the combination of techniques in a complementary manner. Beamlines suitably designed to offer multiple techniques, instead of a single one, can host efficiently such combinatorial studies. In this paper, we present the diverse Soft X-ray microscopy techniques in use at the TwinMic beamline at Elettra Sincrotrone Trieste, namely, STXM combined with XRF spectroscopy, full-field TXM and Ptychography. We demonstrate the capabilities by examining two specific biological samples: U87MG cells exposed to CoFe2O4 nanoparticles and a stem section of a Solanum lycopersicum (tomato) plant. These specimens are representatives of a large sample class used in a wide range of scientific studies. The results show the potential that can be achieved in terms of imaging by accessing X-ray microscopy techniques during a single beamtime access in TwinMic. [ABSTRACT FROM AUTHOR]

Abstract

The last decades have witnessed substantial efforts in the development of several detector technologies for X-ray fluorescence (XRF) applications. In spite of the increasing trend towards performing, cost-effective and reliable XRF systems, detectors for soft X-ray spectroscopy still remain a challenge, requiring further study, engineering and customization in order to yield effective and efficient systems. In this paper we report on the development, first characterization and tests of a novel multielement detector system based on low leakage current silicon drift detectors (SDD) coupled to ultra low noise custom CMOS preamplifiers for synchrotron-based low energy XRF. This new system exhibits the potential for improving the count rate by at least an order of magnitude resulting in ten-fold shorter dwell time at an energy resolution similar to that of single element silicon drift detectors.

Abstract

Aim: The aim of this retrospective study is to evaluate if antiplatelet therapy in elderly patients undergoing surgical excision of nasal non-melanoma skin cancer and contemporary reconstruction with full-thickness skin graft can be related to a better vitality of the graft and consequently improved aesthetic result., Materials and Methods: Patients affected by BCC or SCC of the nose that underwent surgical excision and contemporary reconstruction with full-thickness skin graft were divided into two groups according to antiplatelet therapy. Medications were performed 7 and 15 days after surgery. To asses engraftment, we clinically evaluated the percentage of vital flap recognizing 3 different results: less than 20%, between 20% and 80%, and more than 80% of vital surface. Finally, patients were asked to express a subjective evaluation of the aesthetic result using a numeric scale ranging from 1 to 10. Statistical analyses were performed with SPSS 15.0 for Windows., Results: Twenty-four of the 36 eligible patients took antiplatelet therapy (Group 1). Statistical analysis was very close to demonstrate a significant difference between the two groups after the first evaluation (X2= 3.6; p-value = 0.0578) and it showed a clear significant difference between the two groups after the second evaluation (X2 = 13.5692 e p-value = 0.0002). The average value of the subjective evaluation conducted only on 32 of 36 patients, was 9.12. Any significant difference was observed between the two groups (p-value >0.1)., Conclusions: Our preliminary results seem to suggest that antiplatelet therapy in elderly patients with non-melanoma skin cancer of the nose treated with surgical excision and contemporary reconstruction with fill-thickness skin graft could favor the graft vitality with low risk of bleeding. Further studies will be useful to determinate if antiplatelet drugs can be prescribed in the perioperative period to selected patients presenting risk factors for wound healing to increase the chances of engraftment., Key Words: Antiplatelet Therapy, Non Melanoma Skin Cancer, Skin Graft.
