Fractional flow reserve measurement using dynamic CT perfusion imaging in patients with coronary artery disease.

Purposes: The objective was to evaluate the accuracy of a novel CT dynamic angiographic imaging (CT-DAI) algorithm for rapid fractional flow reserve (FFR) measurement in patients with coronary artery disease (CAD).

Materials And Methods: This retrospective study included 14 patients (age 58.5 ± 10.

Simultaneous measurement of liquid level and R.I. sensor using POF based on twisted structure.

In this paper, a dual-parameter liquid level and refractive index (R.I.) sensor is fabricated using three pieces of bare polymer optical fibers (POFs), which can independently and simultaneously sense the liquid level and R.

An Audit Cycle of Gynecological History Documentation in Emergency Surgical Admissions of Female Patients of Childbearing Age Presenting with Acute Abdominal Pain at a District General Hospital.

Background Ectopic pregnancy (EP) is a significant cause of maternal morbidity and mortality. Accurate and timely diagnosis is crucial, particularly in women of reproductive age presenting with acute abdominal pain. This audit aimed to assess the completeness and accuracy of gynecological history documentation, including pregnancy status, in female patients admitted for emergency surgery due to abdominal pain.

A review on bioactivity, plant safety, and metal-reducing potential of lignin, its micro/nanostructures, and composites.

Modern science focuses on sustainability-oriented innovation. Structurally sophisticated lignin is a sustainable alternative to non-renewable resources. Over the last several years, a tremendous scientific effort has been made to innovate lignin-based sustainable materials for numerous advanced applications.

Do Appendiceal Neuroendocrine Tumors Metastasize Post Appendectomy or Right Hemicolectomy?

Background: Neuroendocrine tumors (NETs) of the appendix are typically detected incidentally during appendectomy. Recent studies reported no metachronous metastases among patients with primary tumors <2 cm, regardless of lymph node status or referral for completion hemicolectomy. However, questions persist regarding the possibility of metastases developing decades after surgical resection, particularly because appendiceal NETs are frequently diagnosed in young adults and children.
