Abstract Background: Neoadjuvant chemotherapy (NAC) significantly enhances clinical outcomes in patients with triple-negative breast cancer (TNBC); however, chemoresistance frequently results in treatment failure. Consequently, understanding the mechanisms underlying resistance and accurately predicting this phenomenon are crucial for improving treatment efficacy. Methods: Ultrasound images from 62 patients, taken before and after neoadjuvant therapy, were collected. Mitochondrial-related genes were extracted from a public database. Ultrasound features associated with NAC resistance were identified and correlated with significant mitochondrial-related genes. Subsequently, a prognostic model was developed and evaluated using the GSE58812 dataset. We also assessed this model alongside clinical factors… More >

Abstract Introduction: Partial gland ablation (PGA) using high intensity focal ultrasound (HIFU) is an alternative to active surveillance for low to intermediate risk localized prostate cancer. This pilot study assessed quality of life (QoL) outcomes during the implementation of PGA HIFU at our institution.
Materials and methods: We prospectively enrolled 25 men with a diagnosis of localized low/intermediate risk prostate cancer who elected to undergo PGA-HIFU in a pilot study at our institution between 2013 and 2016. Patients underwent pre-treatment mpMRI and transrectal ultrasound-guided biopsies. The primary endpoints were impact on patient-reported functional outcomes (erectile, urinary function, QoL)… More >

Abstract The majority of solid testicular tumors are treated with orchiectomy given the high risk of malignancy. We present a case of a testicular mass in an adult patient in the setting of recent hand, foot, and mouth disease that was managed conservatively with serial ultrasounds. Even though cases of viral-associated testicular masses are rare, this differential diagnosis should be considered in patients with a new testicular mass in the setting of recent viral infection and negative tumor markers. For these patients, observation may be an option instead of immediate orchiectomy. More >

Abstract Introduction: Prostate cancer is the third leading cause of death from cancer among Canadian men. High intensity focused ultrasound (HIFU) is a novel approach for primary treatment of localized prostate cancer. Little is known, however, about its costs. We aimed to collect the direct costs and health-related quality of life (HRQoL) data of HIFU in primary treatment of localized low and intermediate risk prostate cancer in Ontario.
Materials and methods: We collected direct costs and HRQoL data of 20 patients with localized low or intermediate risk prostate cancer who received whole gland HIFU at a privately owned… More >

Abstract Postharvest losses remain a significant challenge, particularly in developing countries that have inadequate infrastructure. Medicinal plants offer an eco-friendly and sustainable solution for managing diseases and pests in agricultural systems. These plants are rich in bioactive compounds, such as alkaloids, flavonoids, terpenoids, phenolics, and essential oils, many of which have proven antimicrobial, antifungal, insecticidal, and antioxidant properties. These characteristics make medicinal plants viable candidates for postharvest disease and pest control. Among these, Larrea tridentata (creosote bush) is particularly notable for its bioactive compounds with strong antifungal properties. Their potential applications include agriculture, food preservation, and medicine.… More > Graphic Abstract

Abstract Aqueous zinc batteries have attracted wide interest due to the high safety of the non-flammable electrolyte. However, the inhomogeneous metal plating during the charging and discharging process generates uncontrollable dendrite growth on the anode surface, which seriously threatens the performance and lifetime of the battery. Herein, we provide a physical method to fragment zinc dendrites by using ultrasound to induce cavitation effects in the electrolyte, which can effectively improve the dielectric structure defects inside the battery and reduce the risk of short circuit. The experimental results show that the roughness and height of zinc deposits More >

Abstract In the present research, we describe a computer-aided detection (CAD) method aimed at automatic fetal head circumference (HC) measurement in 2D ultrasonography pictures during all trimesters of pregnancy. The HC might be utilized toward determining gestational age and tracking fetal development. This automated approach is particularly valuable in low-resource settings where access to trained sonographers is limited. The CAD system is divided into two steps: to begin, Haar-like characteristics were extracted from ultrasound pictures in order to train a classifier using random forests to find the fetal skull. We identified the HC using dynamic programming,… More >

Abstract The intensification of physicochemical processes in the sonochemical reactor chamber is widely used in problems of synthesis, extraction and separation. One of the most important mechanisms at play in such processes is the acoustic cavitation due to the non-uniform distribution of acoustic pressure in the chamber. Cavitation has a strong impact on the surface degradation mechanisms. In this work, a numerical calculation of the acoustic pressure distribution inside the reactor chamber was performed using COMSOL Multiphysics. The numerical results have revealed the dependence of the structure of the acoustic pressure field on the boundary conditions More > Graphic Abstract

Abstract Ultrasonic baths and sonochemical reactors are widely used in industrial applications dealing with surface cleaning and chemical synthesis. The processes of erosion, cleaning and structuring of the surface can be typically controlled by changing relevant influential parameters. In particular, in this work, we experimentally investigate the effect of NaCl concentration (0–5.5 mol/L) on the erosion of an aluminum foil under ultrasonic exposure at a frequency of 28 kHz. Special attention is paid to the determination of cavitation zones and their visualization using heat maps. It is found that at low NaCl concentration (0.3 mol/L), the More > Graphic Abstract

Abstract Breast cancer detection heavily relies on medical imaging, particularly ultrasound, for early diagnosis and effective treatment. This research addresses the challenges associated with computer-aided diagnosis (CAD) of breast cancer from ultrasound images. The primary challenge is accurately distinguishing between malignant and benign tumors, complicated by factors such as speckle noise, variable image quality, and the need for precise segmentation and classification. The main objective of the research paper is to develop an advanced methodology for breast ultrasound image classification, focusing on speckle noise reduction, precise segmentation, feature extraction, and machine learning-based classification.
