Shock-induced star formation in a model of the Mice
نویسنده
چکیده
Star formation plays an important role in the fate of interacting galaxies. To date, most galactic simulations including star formation have used a density-dependent star formation rule designed to approximate a Schmidt law. Here, I present a new star formation rule which is governed by the local rate of energy dissipation in shocks. The new and old rules are compared using self-consistent simulations of NGC 4676; shockinduced star formation provides a better match to the observations of this system.

The effect of lamotrigin on stress-induced behavioral and biochemical changes in mice
Stress may cause special behavioral and biochemical changes. Kindling is presumed to be the underlying mechanism for such changes. Lamotrigin, an anti-kindling agent which blocks glutamate release through inhibiting sodium channels may reverse these behavioral changes. The aim of this study was to explore the effects of lamotrigin in management of behavioral and biochemical changes caused by st...
متن کاملProtective effect of crocin on electromagnetic field-induced testicular damage and heat shock protein A2 expression in male BALB/c mice
Objective(s): Exposure to electromagnetic fields (EMF) emitted from mobile phones may cause a deleterious effect on human health and may affect the male reproductive system. Crocin, a carotenoid isolated from Crocus Sativus L. (Saffron), is a pharmacologically active component of saffron. So, this study was conducted to investigate the protective effect of crocin on t...
متن کاملWedelolactone from Vietnamese Eclipta prostrata (L.) L. protected zymosan-induced shock in mice
Wedelolactone is known to have biological activities such as anti-inflammation hepatitis, anti-hepatotoxic activity, and trypsin inhibitory effect. However, up to date, there has not been studied deeply in the role of wedelolactone for zymosan-induced signaling pathways in the process of regulating the excessive inflammatory responses in host. Here, we demonstrated that wedelolactone plays an e...

Background and purpose: Many herbs including Euphorbia have immunomodulatory properties. The aim of this study was to evaluate the immunomodulatory effects of the ethanolic extract of E.myrsinites. Materials and methods: In this experimental study, 40 Swiss albino male mice were randomly divided into 4 groups. Group A included healthy mice, group B was induced by lipopolysaccharide (LPS), grou...
متن کاملNMDA glutamate receptor inhibition in the dorsal hippocampus reduced the maintenance of electric foot shock stress -induced anxiety and depression like behaviors in mice
Introduction: In the present study, the effect of inhibition of glutamate NMDA receptors located in the dorsal hippocampus on the maintenance of anxiety and depression like behaviors induced by electric foot shock stress was investigated. Materials and Methods: NMARI male mice were divided into two categories. The first category received electro foot shock for 30 minutes after injection of mema...
