Rapid Onset Vasodilation during Baroreceptor Loading and Unloading
Am J Physiol Regul Integr Comp Physiol. 2023 Sep 11. doi: 10.1152/ajpregu.00116.2023. Online ahead of print.ABSTRACTThe purpose of these experiments was to determine if the increase in vascular conductance following a single muscle contraction (50% MVC) (6 male & 6 female subjects) was altered by baroceptor loading and unloading. Rapid onset vasodilation (ROV) was determined by measuring brachial artery blood flow (Doppler ultrasound), and blood pressure (Finapress). Brachial artery vascular conductance was calculated dividing blood flow by mean arterial pressure. ROV was described by the area under the ∆VC-time curv...

The effects of biological sex and oral contraception on the sympathetic neurocirculatory adjustments to static handgrip exercise in humans
Am J Physiol Regul Integr Comp Physiol. 2023 Sep 11. doi: 10.1152/ajpregu.00147.2023. Online ahead of print.ABSTRACTBiological sex affects the neurocirculatory adjustments to fatiguing exercise. However, the effects of sex and oral contraceptive pills (OCPs) on sympathetic action potential (AP) emission patterns and the transduction of AP discharge into vasoconstriction during static handgrip (SHG) exercise remains unknown. We tested the hypothesis that males, and females using OCPs, would demonstrate larger increases in sympathetic activation and sympathetic vascular transduction compared to naturally menstruating females...

Effect of ultrasound on mass transfer during vacuum impregnation and selected quality parameters of products: A case study of carrots
Ultrason Sonochem. 2023 Sep 6;99:106592. doi: 10.1016/j.ultsonch.2023.106592. Online ahead of print.ABSTRACTMany unit operations in the food industry are diffusional driven. These processes are usually very slow and difficult to handle for specific groups of raw materials. Vacuum impregnation (VI) is one example. Impregnating low-porous or densely-structured materials is problematic and often requires low pressure, which can negatively affect product quality and be expensive in energy consumption. This research aimed to evaluate ultrasound (US) as a factor in intensifying mass transfer and enhancing its effectiveness in th...

A Comprehensive Review of Myocardial Bridging: Exploring Diagnostic and Treatment Modalities
Cureus. 2023 Aug 8;15(8):e43132. doi: 10.7759/cureus.43132. eCollection 2023 Aug.ABSTRACTMyocardial bridging (MB) is a congenital coronary artery anomaly involving an overlying myocardium's partial or complete encasement of a coronary artery segment. The obstruction can lead to significant cardiac symptoms, resulting in myocardial ischemia, arrhythmia, and sudden cardiac death. Several approaches, including invasive and non-invasive methods, have been proposed to diagnose and manage MB. Invasive modalities, such as intravascular ultrasound (IVUS) and coronary angiography, offer high specificity and sensitivity. In contrast...

Functional Alterations of the Basal Ganglia Are Associated with Voluntary Activation of the Core Stabilizing Muscles in Patients with Chronic Low Back Pain: A Cross-Sectional Study
CONCLUSIONS: Grey matter alterations may be confined to regions responsible for perception, motor control, and emotion regulation in patients with CLBP. The interrupted EC from the basal ganglia to the default mode network might be involved in the impairment of voluntary activation of the core stabilizing muscles.PMID:37693681 | PMC:PMC10484657 | DOI:10.1155/2023/2028379

Comparison of microvascular flow imaging and contrast-enhanced ultrasound for blood flow analysis of cervical lymph node lesions
CONCLUSION: Both CEUS and MVFI are valuable in differentiating benign and malignant lesions of lymph nodes and have a similar diagnostic performance; however, MVFI is less invasive and simpler than CEUS. Therefore it is preferred for auxiliary examination of enlarged lymph nodes that are difficult to diagnose by conventional ultrasound.PMID:37694358 | DOI:10.3233/CH-231860
