A new approach to 'on-demand' treatment of lifelong premature ejaculation by treatment with a combination of a 5-HT receptor antagonist and SSRI in rats.

Lifelong premature ejaculation (PE) in men lacks an adequate on-demand pharmacological treatment. Although selective serotonin reuptake inhibitors (SSRIs) are used for PE they only work after chronic treatment, or if used on-demand, less adequately than chronic SSRI treatment. It has been shown that the addition of a behaviorally silent 5-HT-receptor antagonist to an SSRI can generate acute inhibitory effects on male rat sexual behavior.

Use of passive detectors to characterize neutron field hardness.

Most personnel neutron dosimeters and field monitors suffer from an energy dependence. The knowledge of the energy distribution of the measured neutron field is necessary to correct the response of the detectors. However, the response of the detectors can be significantly improved when only a simple idea of the spectrum hardness is available.

The fission track detector revisited: application to individual neutron dosimetry.

A system based on fission fragment tracks had previously been developed for individual neutron dosimetry. The dosimeter detects both fast neutrons by means of the 232Th(n,f) reaction, and thermal and albedo neutrons by means of the 235U(n,f) reaction. The fission tracks produced in a plastic foil are chemically etched and counted by spark discharges.

Return to normality after a radiological emergency.

Some preliminary considerations from the management of post-accident situations connected to large scale and high land contamination are presented. The return to normal, or at least acceptable living conditions, as soon as reasonably achievable, and the prevention of the possible emergence of a post-accident crisis is of key importance. A scheme is proposed for understanding the dynamics of the various phases after an accident.
