Effect of intrauterine marijuana exposure on fetal growth patterns and placental vascular resistance.

Objective: The recent legalization of marijuana has increased overall use, including in pregnancy. Studies have previously associated marijuana use with adverse fetal neurodevelopmental outcomes. We sought to compare fetal sonographic growth parameters and placental perfusion, as measured by umbilical artery Dopplers, in women using daily marijuana versus nonusers.

Effective remediation of fish processing waste using mixed culture biofilms capable of simultaneous nitrification and denitrification.

Fish processing waste water causes pollution and eutrophication of water bodies when released untreated. Use of bacteria capable of simultaneous nitrification and denitrification (SND) as biofilms on carriers in a moving bed bioreactor (MBBR) is a popular approach but seldom used for fish processing waste water remediation. Here, we studied the variations in biofilm formation and application activities by isolates Lysinibacillus sp.
