Article Abstract
Truffle, the hypogeous, ascomycetous macrofungus, has been recognized as a delicacy for centuries, and it is gaining elevated status in the culinary domain. The chemical composition and biological activities of aqueous extract and ground material of two desert Tunisian and were studied for the first time. Using three assays antioxidant activity of the aqueous extract and ground material of the two truffles were investigated. Indeed, the aqueous extract and ground material of showed the highest capacity for the DPPH scavenging test (IC = 0.18 mg/mL) and with regard to the chelating power of iron (IC = 0.22 mg/mL). At the same time, the highest capacity for iron reduction was recorded in the crude material of . Besides, the total phenolic, flavonoid, flavanol, tannin, and proanthocyanidin contents of both truffles extracts were determined. The ground material showed the best antibacterial activity for two ascomycetes against seven strains of bacteria. HPLC analysis of aqueous extracts showed that the predominant phenolic compounds in and were gallic acid (33.25%) and myricetin (52.91%). Therefore, these truffles are a source of natural antioxidant and antimicrobial agents and could be used as a potential health food.

Generative artificial intelligence for automated data extraction from unstructured medical text.
JAMIA Open
October 2025
Division of Pulmonary and Critical Care, Brigham and Women's Hospital, Boston, MA, United States.
Objectives: Unstructured data, such as procedure notes, contain valuable medical information that is frequently underutilized due to the labor-intensive nature of data extraction. This study aims to develop a generative artificial intelligence (GenAI) pipeline using an open-source Large Language Model (LLM) with built-in guardrails and a retry mechanism to extract data from unstructured right heart catheterization (RHC) notes while minimizing errors, including hallucinations.
Materials And Methods: A total of 220 RHC notes were randomly selected for pipeline development and 200 for validation from the Pulmonary Vascular Disease Registry.
Evaluation of algorithmic requirements for clinical application of material decomposition using a multi-layer flat panel detector.

Otto von Guericke University, Institute for Medical Engineering and Research Campus STIMULATE, Magdeburg, Germany.
Purpose: The combination of multi-layer flat panel detector (FPDT) X-ray imaging and physics-based material decomposition algorithms allows for the removal of anatomical structures. However, the reliability of these algorithms may be compromised by unaccounted materials or scattered radiation.
Approach: We investigated the two-material decomposition performance of a multi-layer FPDT in the context of 2D chest radiography without and with a 13:1 anti-scatter grid employed.

Background: Al-Zahraa Teaching Hospital, one of the most important hospitals in Iraq, is currently facing extensive organizational problems. One reason for these problems is the lack of attention to the voice of the employees, which can be due to a lack of designing an appropriate model for this phenomenon.
Materials And Methods: Accordingly, the present interpretive, qualitative, and exploratory research mainly aimed at designing a voice pattern for the employees in Al-Zahraa Teaching Hospital in Iraq.

The representation of the electronic structure of benzene is important for understanding the properties of planar and monocyclic organic carbon compounds. Resonant Kekulé and conjugated structures based on localized and delocalized electronic theories, respectively, can be used to depict the ground state of benzene; however, depictions of its electrons vibrating in the excited states remain to be clarified. This paper presents a novel algorithm for exploring the three lowest lying vertically singlet excited states of benzene, focusing on the electronic excitations between occupied π and unoccupied π* orbitals.

Electric droplet sorting is widely applied in the screening of target molecules, cells, drugs, and microparticles. Previous studies have made several optimizations on the electrode materials, structures, and arrangements. However, voltages of over 1 kV are required to realize droplet sorting, which causes the undesired droplet splitting.
