The X-ray emission from the faintest X-ray elliptical and S0 galaxies is characterized by a hard ∼5 keV component, and a very soft ∼0.2 keV component. The hard component has generally been regarded as the integrated emission from low mass X-ray binaries (LMXBs), but the origin of the soft component is unknown. We present evidence which suggests that LMXBs also exhibit a soft component, which is...

Soft X-ray absorption spectroscopy coupled with nano-scale microscopy has been widely used in material science, environmental science, and physical sciences. In this work, the advantages of soft X-ray absorption spectromicroscopy for plant biopolymer research were demonstrated by determining the chemical sensitivity of the technique to identify common plant biopolymers and to map the distributi...

Objective: To examine the efficacy of combined use intranasal steroids, antibiotics and monteleukast for improving adenotonsillar hypertrophy.
 Materials Methods: This prospective study was done at Bangladesh ENT Hospital, Dhaka from January 2020 to June 2021. 50 children were included with primary symptoms mouth breathing, snoring sleep disturbances. X-ray soft tissue nasopharynx lateral ...

Porous scaffolds based on poly(α-hydroxy-esters) are under investigation in many tissue engineering applications. A biological response to these materials is driven, in part, by their three-dimensional (3D) structure. The ability to evaluate quantitatively the material structure in tissue-engineering applications is important for the continued development of these polymer-based approaches. X-ra...

Background & Aims: Tibia fractures are the most common long bone fracture. Due to minimal soft tissue and its blood supply, inadequate treatment of injuries could be a major cause of morbidity and disability. The intramedullary nail is the preferred method of treatment; however, despite all previous studies, no accurate method to measure nail length prior to surgery exists as yet. Due to the im...

The soft X-ray microscope at the Lawrence Berkeley National Laboratory was developed for visualization of biological tissue. Soft X-ray microscopy provides high-resolution visualization of hydrated, non-embedded and non-sectioned cells and is thus potentially an alternative to transmission electron microscopy. Here we show for the first time soft X-ray micrographs of structures isolated from th...

X-ray phase-contrast imaging is a promising approach for improving soft-tissue contrast and lowering radiation dose in biomedical applications. While current tabletop imaging systems adapt to common x-ray tubes and large-area detectors by employing absorptive elements such as absorption gratings or monolithic crystals to filter the beam, we developed nanometric phase gratings which enable table...

Chest X-ray ( fig. 1 a, arrows) and a contrast-enhanced CT scan ( fig. 1 b) demonstrated a well-defined, homogeneous, pleural soft-tissue mass close to the right diaphragm. It was slightly enhanced, similar to that of a normal liver without any anatomic connection with subpleural, normal liver. A diagnostic CT-guided transthoracic A 65-year-old female who had never smoked presented with an abno...
