We determine the equilibrium chain end probability density [Formula: see text] for a one-dimensional ideal chain of N monomers grafted to a planar surface. This distribution is also the distribution function of a three-dimensional chain where the tangential dimensions y, z are integrated out of the distribution. With a…

We present a method and setup that provide complementary three-dimensional (3D) images of blood oxygenation (via quantitative photoacoustic imaging) and blood flow dynamics (via ultrasound Doppler). The proposed approach is label-free and exploits blood-induced fluctuations, and is implemented on a sparse array with on…

BACKGROUND: Previous studies report varying rates of time-loss injuries in adolescent female soccer, ranging from 2.4 to 5.3 per 1000 athlete-exposures or 2.5 to 3.7 per 1000 hours of exposure. However, these studies collected data using traditional injury reports from coaches or medical staff, with methods that signif…

This article examines Pubget, a free Web-based search engine for life sciences researchers for conducting searches of the medical literature and retrieving full-text PDFs. Its search functionality and add-on features are evaluated to determine potential for library instruction and promotion. With many libraries relying…

Probiotics can be applied in therapy and mainly in prevention of many civilization disorders. Experimental studies in animal models and clinical trials of patients with inflammatory bowel disease (IBD) have consistently shown that the use of probiotic organisms may effectively down-modulate the severity of intestinal i…

To determine the reliability of knee joint sonography in the evaluation of gouty arthritis.A search of Google Scholar, PubMed, NCBI, MEDLINE, and Medscape databases, from 1988 up to 2020. The key search terms used were knee joint; knee joint ultrasound; gout; gouty arthritis, knee joint pain; sensitivity; specificity.…

A report published in 2000 from the Institute of Medicine revealed that medical errors were a leading cause of patient deaths, and urged the development of error detection and reporting systems. The field of radiation oncology is particularly vulnerable to these errors due to its highly complex process workflow, the la…

BACKGROUND: Large language models (LLMs) such as GPT-4 can interpret free text, but unreliable answers, opaque reasoning, and privacy risks limit their use in healthcare. In contrast, rule-based artificial intelligence (AI) provides transparent and reproducible results but struggles with free text. We aimed to combine…

The overall design of the CIS at CPMC is heavily influenced by the decision support component. The type of automated decision support being implemented dictates the need for highly structured or coded data. The value of decision support systems has been well documented. The current reliance on free-text documents is na…

The OSTMED.DR® database provides access to both citation and full-text osteopathic literature, including the Journal of the American Osteopathic Association. Currently, it is a free database searchable using basic and advanced search features.

OBJECTIVE: PubMed is the world's largest online collection of biomedical literature citations. A PubMed search (October 11, 2019) using the medical subject heading terms "history" and "mastoidectomy" was conducted. The heading "best matches" listed as first article "A brief history of mastoidectomy," a very relevant fr…

While reviewing the available literature, we noticed comorbidity of epilepsy and psychiatric disorders. Psychiatric disorders were observed more frequently in patients with high seizure frequency. There is significant prevalence of epilepsy comorbidity with depression, anxiety disorders, and to a lesser extent with bip…

For over two decades, valuable insights have been accumulated from epidemiologic studies and randomized trials about the risks and prevention of atrial fibrillation. Atrial fibrillation (AF) substantially raises the risk of stroke, most likely through an atrio-embolic mechanism. Warfarin and other members of its class…

The UK has a significant and growing population of older adults with frailty and complex healthcare needs, necessitating innovative care solutions. This study aimed to explore patients' and carers' experiences of a novel integrated service that was set up to address the increasing healthcare needs of older people livin…

PURPOSE: To assess British doctors' work-life balance, home-life satisfaction and associated barriers. STUDY DESIGN: We designed an online survey using Google Forms and distributed this via a closed social media group with 7031 members, exclusively run for British doctors. No identifiable data were collected and all r…

A new natural language processing (NLP) application for COVID-19 related information extraction from clinical text notes is being developed as part of our pandemic response efforts. This NLP application called DECOVRI (Data Extraction for COVID-19 Related Information) will be released as a free and open source tool to…

This paper presents a novel silicon-based metasurface-coated one-dimensional (1D) slab waveguide. The proposed idea can easily engineer and mold guided waves into any desired free-space mode and provide the wavefront control of optical metasurfaces, such as out-of-plane beam deflection and focusing. As an example of ap…

In this paper, the role of gradient micro-inertia terms [Formula: see text] and free micro-inertia terms [Formula: see text] is investigated to unveil their respective effects on the dynamic behaviour of band-gap metamaterials. We show that the term [Formula: see text] alone is only able to disclose relatively simplifi…

We report here on focusing of a probe IR (λ = 1.55 μm) laser beam in silicon. The focusing is done by a second pump laser beam, at λ = 0.775 μm and 30 ps pulse width, with a donut shape that is launched collinearly and simultane…

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…
