Aim: The aim of this study was to quantify the uterine positional displacement induced by ultrasound probe pressure on a phantom and address the daily uterine motion in a healthy volunteer.
Materials & Methods: The phantom mimics the female pelvic region. The incorporated organs were subjected to displacement. A total of 42 phantom scans and 16 volunteer scans were acquired. The uterine shifts were measured in three directions.
Results & Discussion: The difference of uterine positional displacements, using pressure versus without pressure on the phantom, was not statistically significant. The daily uterine positional variations of the volunteer were larger than the probe pressure induced displacements.
Conclusion: The larger daily uterine shifts of the volunteer outweighed the submillimeter impact of the probe pressure in all directions.

The physical microenvironment plays a crucial role in tumor development, progression, metastasis and treatment. Recently, we proposed four physical hallmarks of cancer, with distinct origins and consequences, to characterize abnormalities in the physical tumor microenvironment: (1) elevated compressive-tensile solid stresses, (2) elevated interstitial fluid pressure and the resulting interstitial fluid flow, (3) altered material properties (for example, increased tissue stiffness) and (4) altered physical micro-architecture. As this emerging field of physical oncology is being advanced by tumor biologists, cell and developmental biologists, engineers, physicists and oncologists, there is a critical need for model systems and measurement tools to mechanistically probe these physical hallmarks.

Objective: In this feasibility study, firstly, we aimed to assess whether intramuscular pH (IMpH) could be measured with a glass-tipped electrode. Secondly, we aimed to explore whether we could monitor changes in skeletal muscle pH before and throughout static (isometric) and after dynamic (treadmill) exercise, comparing individuals with intermittent claudication (IC) to a group of healthy controls.
Methods: Forty participants with IC (mean age ± SD) 68 ± 8) and 40 healthy volunteers (63 ± 10) were recruited.

Ferulic acid (FA) is a phenolic compound obtained naturally and is a versatile antioxidant identified for its potential in managing hypertension. However, its application is constrained due to its classification as a BCS Class IV moiety. To address this, we concentrated on improving its solubility and permeability by developing nanostructured lipid carriers (NLCs) of FA using emulsification probe sonication technique.

The fluorescence detection of amino compounds and the evaluation of their content in environmental samples are vital, not only for assessing food quality but also for studying soil organic matter. Here, we present the synthesis and application of a novel fluorescent probe, 4-(9-acridone)benzylmethyl carbonochloride (APE-Cl), for detecting amino compounds via a chloroformate reaction with fluorescence detection. The complete derivatization reaction of APE-Cl with amino compounds can be accomplished in aqueous acetonitrile within 5 min at room temperature, using 0.
