Non-surgical management of patients with ectopic pregnancy: A review

An ectopic pregnancy is a medical emergency. Currently, surgery is the main method of therapy, and non-surgical management with methotrexate is considered an acceptable alternative. Methotrexate is a folic acid antagonist and has an inhibitory effect on the proliferation of trophoblast cells. There are various methotrexate regimens; the choice is based on the level of β-subunit of human chorionic gonadotropin, the location of the ectopic pregnancy and the patient's adherence to treatment. Therapy of ectopic tubal pregnancy with methotrexate is an effective and safe alternative to surgical treatment, does not affect the ovarian reserve and preserves the woman's fertility

ClusterFluctons Revelation in Nuclear Interactions at 4.2 (GeV/c)/N

Total longitudinal momentum of all registered particles, their total energy and other total kinematics' variables are used for separation of the events with two and three quazinucleon collisions from C+C, C+p, d+C and p+C interactions at 4.2 (GeV/c)/N. The research results on charged particles multiplicity and their momentum spectra lead to the conclusion that nearly 60 \% of all three quazinucleon events are due to collisions where two nucleons behave like a whole object, called flucton, which has been predicted by D. I. Blokhintsev. Mean values of oneparticle longitudinal momenta of the products and their mean multiplicities for the subreactions in which fluctons take part at the interactions are lower by \approx 30\% compared to the subreactions where two nucleons interact not as a whole object but on a successive way. Production of the cumulative particles is due to flucton interactions, especially in the case where fluctons are used as targets

Collective Flow Phenomena of Protons and π−\pi^{-} Mesons in Nucleus-Nucleus Collisions at a Momentum of 4.2÷4.54.2\div 4.5 GeV/cc per Nucleon

The collective properties of protons and $\pi^{-}$ mesons in He-C, C-C, C-Ne, C-Cu and C-Ta collisions at a momentum of $4.2\div 4.5$ GeV/$c$ per nucleon ($E=3.4\div3.7$ GeV/nucleon) have been investigated. The data is obtained by SKM-200-GIBS and 2-m Propane Bubble Chamber of JINR. The directed (in-plane) protons and $\pi^{-}$ mesons have been observed in the above-mentioned interactions. In He-C, C-C and C-Ne interactions the directed flow of $\pi^{-}$ mesons is in the same direction as for protons, while in C-Cu and C-Ta collisions pions show antiflow behaviour
