Actinomycosis is an infrequent chronic progressive granulomatous and suppurative disease caused by Actinomyces israelii, a natural inhabitant of the gastrointestinal tract. We report a rare case of a 68-year-old man with primary endobronchial actinomycosis who presented in the emergency respiratory ward with massive he…

BACKGROUND: Biomedical scientists need to access figures to validate research facts and to formulate or to test novel research hypotheses. However, figures are difficult to comprehend without associated text (e.g., figure legend and other reference text). We are developing automated systems to extract the relevant expl…

Background The prevalence of thyroid transcription factor-1 (TTF-1) and napsin A expression are poorly characterized in lung core biopsies of small cell carcinoma. Locally, the TTF-1 clone is 8G7G3/1 (Agilent/Dako), and the napsin A clone is IP64 (Leica Biosystems). Methods All in-house lung core biopsy reports for cas…

Mid-infrared (IR) spectral region is of immense importance for astronomy, medical diagnosis, security and imaging due to the existence of the vibrational modes of many important molecules in this spectral range. Therefore, there is a particular interest in miniaturization and integration of IR optical components. To th…

The EMBL-EBI provides free access to popular bioinformatics sequence analysis applications as well as to a full-featured text search engine with powerful cross-referencing and data retrieval capabilities. Access to these services is provided via user-friendly web interfaces and via established RESTful and SOAP Web Serv…

PURPOSE: Gliomas are the commonest malignant brain tumours. Baseline characteristics on structural MRI, such as size, enhancement proportion and eloquent brain involvement inform grading and treatment planning. Currently, free-text imaging reports depend on the individual style and experience of the radiologist. Standa…

Despite the amount of theorization on the forms and effects of participation, relatively little research directly examines what the concept of workplace participation entails in the minds of employees, and whether employees across cultures think positively when the concept of participation is activated in their mental…

The front cover artwork is provided by the Mosquera group at Montana State University, Bozeman. The image shows theoretical elements involved in the density-functional calculations that are free of spurious fractional charges. Read the full text of the Research Article at 10.1002/cphc.202200592.

Invited for the cover of this issue are Sabine Schneider, Tobias A. M. Gulder and co-workers at Technical University of Dresden, Technical University of Munich and Ludwig-Maximillians-University Munich. The image depicts the crystal structure of the cytochrome P450 AryC from arylomycin biosynthesis. Read…

The 5G communication system has experienced a substantial expansion of the spectrum, which poses higher requirements to radio frequency (RF) filters in enhancing their operating frequencies and bandwidths. To this end, this work focused on solving the filtering scheme for challenging 5G n77 and n78 bands and successful…

The Internet has made finding evidence for clinical practice fairly easy. Many different types of databases that can be searched for relevant key terms are available for free or for subscription. Bibliographic or library databases contain books, book chapters, reports, citations, abstracts, and either the full text of…

The Carbohydrate Structure Database (CSDB, http://csdb.glycoscience.ru/ ) is a free curated repository storing various data on glycans of bacterial, fungal and plant origins. Currently, it maintains a close-to-full coverage on bacterial and fungal carbohydrates up to the year 2020. The CSDB web-interface provides free…

Pediatric cancer nursing is a deeply fulfilling yet highly stressful profession as nurses support families during times of intense emotional distress. This study examined the factors influencing job satisfaction among pediatric cancer nurses across Australia and their recommendations to address workplace challenges.A c…

INTRODUCTION: Vascularized free fibula flap is one of the commonly used flaps in autologous soft-tissue and osseous reconstructions in the modern era. While there is abundant literature available on the variable branching pattern and course of the popliteal artery, tibial arteries, and dorsalis pedis artery, there is a…

Pilomatrixoma is a rare skin neoplasm which is usually localized on face, neck and lower extremites and its etiology is still unknown. We report a case of a 32-year-old male patient with a rare localisation of pilomatrixoma on the right shoulder. The presumed diagnosis was sebaceous cyst. Excision biopsy was performed…

BACKGROUND: Smoking remains a leading cause of preventable death and illness. Internet interventions for smoking cessation have the potential to significantly impact public health, given their broad reach and proven effectiveness. Given the dose-response association between engagement and behavior change, identifying s…

Wear-free sliding between two contacted solid surfaces is the ultimate goal in the effort to extend the lifetime of mechanical devices, especially when it comes to inventing new types of micro-electromechanical systems where wear is often a major obstacle. Here we report experimental observations of wear-free sliding f…

MOTIVATION: Converting the vast quantity of free-format text found in journals into a concise, structured format makes the researcher's quest for information easier. Recently, several information extraction systems have been developed that attempt to simplify the retrieval and analysis of biological and medical data. M…

BACKGROUND: Large Language Models (LLMs) have raised broad expectations for clinical use, particularly in the processing of complex medical narratives. However, in practice, more targeted Natural Language Processing (NLP) approaches may offer higher precision and feasibility for symptom extraction from real-world clini…

Ultrafast power Doppler imaging (uPDI) using high-frame-rate plane-wave transmission is a new microvascular imaging modality that offers high Doppler sensitivity. However, due to the unfocused transmission of plane waves, the echo signal is subject to interference from noise and clutter, resulting in a low signal-to-no…
