Thrcc imagc proccssing problems servc as an cxarnplc of thc algorithmic diffcrcnccs causcd by the mapping mcthods. For thc invcstigatcd 2D proccs...

[1] Significant changes of the thermohaline circulation (THC) are likely to cause abrupt climate change. Here we intend to find a simple measure to detect changes in THC through examining several factors proposed to control the THC variations using a coupled climate model. These factors are equatorial-South Atlantic upper ocean temperature, Southern Ocean freshening, inter-basin sea surface sal...

cancer effects (anti-proliferative and anti-migration effects).1–11) 9-THC’s biological activities, its recognized endocrine-disrupting effects, including anti-estrogenic activity, have been the subjects of previous investigations. It has been reported that chronic oral administration of marijuana resin is able to reduce fertility in female rats.12,13) 9-THC on reproductive behavior has been su...

Four different types of feed materials derived from the hemp plant were identified: hemp seed, hemp seed meal/cake, hemp seed oil and whole hemp plant (including hemp flour). The hemp varieties allowed for cultivation in Europe need not to exceed 0.2 % THC (in dry matter; average of 2151 samples collected in Europe between 2006 and 2008: 0.075 %). Hemp seeds are practically free of THC (maximum...

The effects of hormone status and age on the development of tolerance to Δ(9)-THC were assessed in sham-operated (intact) or ovariectomized (OVX) female rats that received either intraperitoneal saline or 5.6 mg/kg of Δ(9)-THC daily from postnatal day (PD) 75-180 (early adulthood onward) or PD 35-140 (adolescence onward). During this time, the four groups for each age (i.e., intact/saline, inta...

We evaluated delta-9 tetrahydrocannabinol (Delta9-THC), delta-8 tetrahydrocannabinol (Delta8-THC), CP55,940 (CP55), 1-deoxy-11-hydroxy-Delta8-THC-dimethylheptyl (deoxy-HU210, a CB2-selective cannabinoid that also binds the CB1 receptor) and the endogenous cannabinoid anandamide (ANA) via i.c.v. and/or intrathecal (i.t.) routes of administration, alone and in combination with SR141716A (SR), a C...

Marijuana use remains strikingly high among young users in the U.S., and yet few studies have assessed the effects of delta9-tetrahydrocannabinol (THC) in adolescents compared to adults. This study measured the effects of THC on male adolescent and adult rats in the Morris water maze. In Experiment 1, adolescent (PD=30-32) and adult (PD=65-70) rats were treated acutely with 5.0 mg/kg THC or veh...

Cannabinoid receptors in the brain (CB(1)) take part in modulation of learning, and are particularly important for working and short-term memory. Here, we employed a delayed-matching-to-place (DMTP) task in the open-field water maze and examined the effects of cannabis plant extracts rich in either Delta(9)-tetrahydrocannabinol (Delta(9)-THC), or rich in cannabidiol (CBD), on spatial working an...
