Potential of Current Direct Mechanical Testing Methods in Assessing Intraoperative Samples of Aortic Aneurysm Caused by Uncontrolled Arterial Hypertension.
Sovrem Tekhnologii Med
January 2025
Research Intern, Human Anatomy and Histology Department; I.M. Sechenov First Moscow State Medical University (Sechenov University), 8/2 Trubetskaya St., Moscow, 119991, Russia.
Unlabelled: was to investigate the potential of direct mechanical testing methods in clinical practice to assess the strength and elastic-deformative characteristics of intraoperative samples of aortic arch aneurysm caused by uncontrolled arterial hypertension.
Materials And Methods: The study experimental material was the resected parts of the aortic aneurysm obtained during aneurysm replacement surgery in a patient with uncontrolled arterial hypertension. The direct mechanical testing methods such as instrumental indentation and uniaxial extension were used.
The impact of universal mental health screening on stigma in primary schools.
Child Adolesc Psychiatry Ment Health
January 2025
Black Dog Institute, University of New South Wales, Sydney, NSW, Australia.
Background: Primary school students struggling with mental health are less likely than high school students to access mental health care, due to barriers such as mental health stigma and low mental health literacy among children and parents. The near universal reach of schools offers a potential avenue to increase access to mental health care through early identification. The potential risks of this approach also need to be understood.

Trials
January 2025
Department of Electrical and Computer Engineering, Princeton University, Princeton, 08544, NJ, USA.
Background: Phase-3 clinical trials provide the highest level of evidence on drug safety and effectiveness needed for market approval by implementing large randomized controlled trials (RCTs). However, 30-40% of these trials fail mainly because such studies have inadequate sample sizes, stemming from the inability to obtain accurate initial estimates of average treatment effect parameters.
Methods: To remove this obstacle from the drug development cycle, we present a new algorithm called Trend-Adaptive Design with a Synthetic-Intervention-Based Estimator (TAD-SIE) that powers a parallel-group trial, a standard RCT design, by leveraging a state-of-the-art hypothesis testing strategy and a novel trend-adaptive design (TAD).
How Much Data Are Enough? Toward Statistically Robust Adhesion Experiments by Atomic Force Microscopy.
Langmuir
January 2025
Department of Physical Chemistry II, University of Bayreuth, Universitaetsstrasse 30, Bayreuth 95447, Germany.
Direct force measurements by atomic force microscopy (AFM) have become an indispensable analytical tool in the last decades. Force measurements have been widely used for adhesion measurements, often in combination with the colloidal probe technique. For the latter technique, a colloidal particle is attached to the end of an AFM cantilever, proving great flexibility in terms of colloid/surface interaction to be studied.

College of New Energy Materials and Chemistry, Leshan Normal University, Leshan, Sichuan, 614000, PR China; Sichuan Province Key Laboratory of Natural Products and Small Molecule Synthesis, Leshan, Sichuan, 614000, PR China. Electronic address:
Background: The threat of toxic malathion residues to human health has always been a serious food safety issue. The CRISPR/Cas system represents an innovative detection technology for pesticide residues, but its application to malathion detection has not been reported yet. In addition, the multiple-guide RNA (gRNA) powered-CRISPR/Cas biosensor has the advantages of being fast, sensitive and does not require pre-amplification.
