ABSTRACT Electrical Pulsed Field (PEF), of pulse duration in 4 milliseconds, effect on mosquito larvae (Culex pipiens) as aquatic insects is assessed in this work. Mosquito larvae classes have been treated with electric field power values (66.66, 83.33, 100, 116.66 V/cm) with separate pulse number (60) and other classes of various pulse numbers have been treated (20, 40, 60, 80) with power of the electrical

Zinc affects nuclear factor kappa b and DNA methyltransferase activity in C3H cancer fibroblast cells induced by a 2100 MHz electromagnetic field Electromagn. Biol. Med. (IF 1.7) Pub Date : 2022-01-07 D. Duzgun Ergun, N. Pastaci Ozsobaci, T. Yilmaz, D. Ozcelik, M. T. Kalkan
ABSTRACT The use of mobile phones is becoming widespread with the development of technology, and as a result, its effects on human health are becoming more and more important every day. Studies have reported that the electromagnetic field (EMF) emitted by mobile phones may have adverse effects on the biological systems. In order to evaluate the effect of zinc (Zn) on C3H cancer fibroblast cells exposed

Pulsed electromagnetic field alleviates synovitis and inhibits the NLRP3/Caspase-1/GSDMD signaling pathway in osteoarthritis rats Electromagn. Biol. Med. (IF 1.7) Pub Date : 2022-01-07 Jing Liu, Xiarong Huang, Jun Zhou, Lan Li, Hao Xiao, Mengjian Qu, Zhilu Sun
ABSTRACT Low-grade inflammation is a key mediator of the pathogenesis of Osteoarthritis (OA). Pulsed electromagnetic field (PEMF) can improve the symptoms of OA and potentially acts as an anti-inflammatory. The aim of this study was to investigate the effect of the PEMF on OA and its relationship with the NLRP3/Caspase-1/GSDMD signaling pathway.18 Three-month-old Sprague-Dawley (SD) rats were randomly

The effects of long-term doppler ultrasound exposure in the prenatal period on renal tissue physiology in rats Electromagn. Biol. Med. (IF 1.7) Pub Date : 2022-01-30 Fatma Beyazal Celiker, Levent Tümkaya, Tolga Mercantepe, Ertan Zengin, Mehmet Beyazal, Arzu Turan, Hatice Beyazal Polat, Zehra Topal Suzan, Adnan Yılmaz
ABSTRACT Doppler ultrasonography (DUSG) is widely used for fetal evaluations. This study investigated the effects of new generation Doppler ultrasound application at different frequencies during pregnancy on postnatal renal development. Six pregnant female rats were divided into three groups. No procedure was performed on the first (control) group. In the second group, transabdominal DUSG was performed

Numerical investigation of blood flow and red blood cell rheology: the magnetic field effect Electromagn. Biol. Med. (IF 1.7) Pub Date : 2022-01-23 Nazli Javadi Eshkalak, Habib Aminfar, Mousa Mohammadpourfard, Muhammed Hadi Taheri, Kaveh Ahookhosh
ABSTRACT In this study, the motion and deformation of a red blood cell in a Poiseuille flow through microvessels under the effect of a uniform transverse magnetic field is comprehensively investigated to get a better insight into blood hemorheology. The rheology of the RBC and the surrounding blood flow are examined numerically in two dimensions using a Finite Element Method. It is essential to know
