Article Abstract
Unlabelled: Subcritical water extraction (SWE) is a nontoxic, environmentally friendly, and rapid extraction method. This experiment aimed to maximize the apigenin content in parsley extracts using pulsed electric field (PEF) and intense pulsed light (IPL) pretreatment prior to SWE (200 °C for 10 min). The highest apigenin content was 21.17 ± 1.11 mg/g at 2.3 kV/cm, 10-Hz, 3 s by PEF pretreatment, and 14.89 ± 0.41 mg/g at 1,200 V, 60 s by IPL pretreatment. Environmental scanning electron microscopy observations and the electrical disintegration index confirmed that physical damage occurred in the parsley leaves after pretreatment. Physical destruction weakens the structure of parsley leaves and increases the apigenin extraction efficiency. This study found that the combined treatment of SWE with PEF and IPL pretreatments at high temperatures could maximize the extraction efficiency of apigenin from parsley. It can be used in the future to extract high-value-added functional materials in the food industry.

Background: Chagas heart disease (ChD) is a significant public health concern in Latin America, contributing to a high incidence of sudden cardiac death (SCD). Despite advances in heart failure treatment, management of Chagas cardiomyopathy has not progressed accordingly. While ICDs are effective for primary and secondary prevention in other conditions, patients with ChD often experience more frequent episodes of ventricular tachycardia, and ICD use may provide a negative impact and increase mortality.

Electrical pulse stimulation (EPS) represents a useful tool to study exercise-related adaptations of muscle cells in vitro. Here, we examine the metabolic and secretory response of primary human muscle cells from metabolically healthy individuals to the EPS protocol reflecting the episodic nature of real-life exercise training. This intermittent EPS protocol alternates high-frequency stimulation periods with low-frequency resting periods.

Background: Pancreatic cancer (PC) presents a significant therapeutic challenge due to its immunosuppressive tumor microenvironment (TME). Emerging evidence supports the efficacy of high-voltage electrical pulses (HVEPs) in PC treatment, leveraging dual benefits of pancreatobiliary duct integrity maintenance and immunogenicity activation.

Electrical deep brain stimulation is effective for epilepsy suppression, but will lead to neural tissue damage and inflammation due to implantation of electrodes and a pulse generator. Transcranial magnetic and transcranial ultrasound stimulation cannot directly generate effective electrical signals in deep brain regions. Here, the use of piezoelectric nanoparticles is proposed as wireless nanostimulators for deep brain electrical stimulation and minimally invasive suppression of epilepsy.

On-chip terahertz (THz) spectroscopy has attracted growing attention because of its capability of measuring samples far smaller than the Rayleigh diffraction limit. The technique also allows the investigation of nonlinear responses of materials, which is indispensable for the development of ultrafast devices operating with a THz bandwidth. Here, we report the development of an on-chip THz-pump THz-probe spectroscopy technique that enables the study of ultrafast electrical-pulse-induced nonequilibrium phenomena.
