Feasibility studies for imaging e+^{+}e−^{-} annihilation with modular multi-strip detectors

Studies based on imaging the annihilation of the electron (e$^{-}$) and its antiparticle positron (e$^{+}$) open up several interesting applications in nuclear medicine and fundamental research. The annihilation process involves both the direct conversion of e$^{+}$e$^{-}$ into photons and the formation of their atomically bound state, the positronium atom (Ps), which can be used as a probe for fundamental studies. With the ability to produce large quantities of Ps, manipulate them in long-lived Ps states, and image their annihilations after a free fall or after passing through atomic interferometers, this purely leptonic antimatter system can be used to perform inertial sensing studies in view of a direct test of Einstein equivalence principle. It is envisioned that modular multistrip detectors can be exploited as potential detection units for this kind of studies. In this work, we report the results of the first feasibility study performed on a e$^{+}$ beamline using two detection modules to evaluate their reconstruction performance and spatial resolution for imaging e$^{+}$e$^{-}$ annihilations and thus their applicability for gravitational studies of Ps

Effects of 2100 MHz radio frequency radiation on the viscosity of blood and oxidative stress parameters in hypertensive and normal rats

WOS: 000458419600005Background: With the development of technology, human beings are increasingly under the exposure of Radio Frequency Radiation (RFR) (due to wireless technologies, mobile phones, base stations etc). The aim was to investigate the possible effects of Radio Frequency Radiation (RFR) on blood, aorta and heart tissue in hypertensive and non-hypertensive rats with various parameters. Materials and Methods: Male Wistar Albino rats were divided into 4 groups: 1.Control (C), 2.Hypertension (H), 3.RFR, 4.RFR+Hypertension (RFR+H). 60 mg/kg L-Nitroarginine Methyl Ester (L-NAME) was administered for 1 month by oral gavage to induce hypertension. The rats were exposed to 2100 MHz RFR for 60 minutes/day, 5 days/week for 8 weeks. Blood hematocrit, blood and plasma viscosity, malondialdehyde (MDA), total nitric oxide (NOX), and Total sulphydril groups (RSH) / glutathione (GSH) levels in plasma and heart tissue were determined. Histological examination of the aortic wall and left ventricular muscle was performed. Results: RFR exposure resulted in a marked increase in cardiac and plasma MDA and NOX levels and a decrease in RSH/GSH levels (p<0.05). Blood viscosity increased in the hypertensive group with RFR exposure (p<0.05). There was an increase in left ventricular weight and number of muscle cells in hypertensive groups (p<0.05). Conclusion: According Our study suggests that exposure to RFR causes more negative effects on hypertension in terms of oxidative stress and antioxidants in the heart and plasma. Also, RFR exposure showed more prominent left ventricular fibrosis and aortic degenerative effects in hypertensive groups
