The hedonic attributes of cutaneous elicitation play a crucial role in everyday life, influencing our behavior and psychophysical state. However, the correlation between such a hedonic aspect of touch and the Autonomic Nervous System (ANS)-related physiological response, which is intimately connected to emotions, still needs to be deeply investigated. This study reports on caress-like stimuli conveyed to the forearm of 32 healthy subjects through different fabrics actuated by a haptic device, which can control both the strength (i...

The aim of this study is the development of a classification system able to discern between two levels of velocity of a caress-like haptic stimulus, through information gathered from the analysis of the Electrodermal Activity (EDA) dynamics. We designed and performed an experiment where EDA signals were acquired during caress-like stimuli conveyed to 32 healthy volunteers (16 females) by means of four different fabrics (hemp, burlap, velvet and silk) and at two velocity levels (9.4 mm/s and 65 mm/s). CvxEDA model was used to process the EDA signal and extract features from both tonic and phasic components...

Grossamide, a representative lignanamide in hemp seed, has been reported to possess potential anti-inflammatory effects. However, the potential anti-neuroinflammatory effects and underlying mechanisms of action of grossamide are still unclear. Therefore, the present study investigated the possible effects and underlying mechanisms of grossamide against lipopolysaccharide (LPS)-induced inflammatory response in BV2 microglia cells. BV2 microglia cells were pre-treated with various concentrations of grossamide before being stimulated with LPS to induce inflammation...

BACKGROUND: Dietary supplementation with oilseeds can reduce methane emission in ruminants, but only a few common seeds have been tested so far. This study tested safflower (Carthamus tinctorius), poppy (Papaver somniferum), hemp (Cannabis sativa), and camelina (Camelina sativa) seeds in vitro using coconut (Cocos nucifera) oil and linseed (Linum usitatissimum) as positive controls. RESULTS: All the tested oilseeds suppressed methane yield (ml g(-1) dry matter, up to 21%) compared to the non-supplemented control when provided at 70 g oil kg(-1) dry matter, and they were as effective as coconut oil...

Cannabis contains a unique class of compounds known as the cannabinoids. Pharmacologically, the principal psychoactive constituent is Δ(9)-tetrahydrocannabinol (THC). The amount of THC in conjunction with selected additional cannabinoid compounds (cannabidiol/CBD, cannabinol/CBN), determines the strength or potency of the cannabis product. Recently, reports have speculated over the change in the quality of cannabis products, from nearly a decade, specifically concerning the increase in cannabinoid content...

For centuries, hashish and marihuana, both derived from the Indian hemp Cannabis sativa L., have been used for their medicinal, as well as, their psychotropic effects. These effects are associated with the phytocannabinoids which are oxygen containing C21 aromatic hydrocarbons found in Cannabis sativa L. To date, over 120 phytocannabinoids have been isolated from Cannabis. For many years, it was assumed that the beneficial effects of the phytocannabinoids were mediated by the cannabinoid receptors, CB1 and CB2...

Cannabis (Cannabis sativa, or hemp) and its constituents-in particular the cannabinoids-have been the focus of extensive chemical and biological research for almost half a century since the discovery of the chemical structure of its major active constituent, Δ(9)-tetrahydrocannabinol (Δ(9)-THC). The plant's behavioral and psychotropic effects are attributed to its content of this class of compounds, the cannabinoids, primarily Δ(9)-THC, which is produced mainly in the leaves and flower buds of the plant...

Cannabis (hemp and marijuana) is an iconic yet controversial crop. On the one hand, it represents a growing market for pharmaceutical and agricultural sectors. On the other hand, plants synthesizing the psychoactive THC produce the most widespread illicit drug in the world. Yet, the difficulty to reliably distinguish between Cannabis varieties based on morphological or biochemical criteria impedes the development of promising industrial programs and hinders the fight against narcotrafficking. Genetics offers an appropriate alternative to characterize drug vs...

The factors determining gradients of biodiversity are a fundamental yet unresolved topic in ecology. While diversity gradients have been analysed for numerous single taxa, progress towards general explanatory models has been hampered by limitations in the phylogenetic coverage of past studies. By parallel sampling of 25 major plant and animal taxa along a 3.7 km elevational gradient on Mt. Kilimanjaro, we quantify cross-taxon consensus in diversity gradients and evaluate predictors of diversity from single taxa to a multi-taxa community level...

REVIEW
Ethan B Russo
Cannabis has been associated with the treatment of epilepsy throughout history, and if ancient Assyrian sources referring to "hand of ghost" are considered credible, this relationship may span four millennia. A tradition of usage continued in Arabic medicine and Ayurvedic practice in India, which led, in turn, to early experiments in Europe and North America with "Indian hemp." Lack of standardization, bioavailability issues, and ultimately prohibition were all factors in cannabis-based medicines failing to maintain mainstream usage in seizure treatment, but investigation was resumed in the 1970s with interesting signals noted in both laboratory and clinical settings...

The industrial hemp varieties 'Yunma 5' and 'Bamahuoma,' which demonstrate growth vigor and environmental adaptability, have been primarily cultivated in Yunnan and Guangxi, China, respectively, for fiber and seeds. The results of physiological measurements showed the phenotypic differences between the two varieties in response to salt stress. RNA-Seq analysis was first performed on leaves of both varieties sampled at four time intervals (0, 2, 4, 6 days) after treatment with salt (500 mM NaCl) We identified 220 co-up-regulated differentially expressed genes (DEGs) in the two varieties, while 26 up-regulated DEGs and 24 down-regulated DEGs were identified exclusively in the single varieties after 2 days of salt stress...

The impact of biochar properties on acid-extractable organics (AEO) adsorption from oil sands process-affected water (OSPW) was studied. Biochar from wheat straw with the highest ash content (14%) had the highest adsorption capacity (0.59 mg/g) followed by biochar from pulp mill sludge, switchgrass, mountain pine, hemp shives, and aspen wood. The adsorption capacity had no obvious trend with surface area, total pore volume, bulk polarity and aromaticity. The large impact of metal content was consistent with the carboxylates (i...

Cannabis sativa L. is an annual herbaceous crop grown for the production of long extraxylary fibers, the bast fibers, rich in cellulose and used both in the textile and biocomposite sectors. Despite being herbaceous, hemp undergoes secondary growth and this is well exemplified by the hypocotyl. The hypocotyl was already shown to be a suitable model to study secondary growth in other herbaceous species, namely Arabidopsis thaliana and it shows an important practical advantage, i.e., elongation and radial thickening are temporally separated...

There are two main varieties of Cannabis sativa plant, namely, hemp which is cultivated for fiber and seeds and contains low amounts of psychoactive cannabinoids and the other which is cultivated for the drug cannabis or marijuana. Increasing popularity of hemp food products and alleged beneficial effects of cannabinoids in the drug variety of cannabis might lead to confusion in the lay population and unintentional ingestion of marijuana, as described in this case report. During a workshop on the use of hemp for medicinal purposes, there was a degustation of various hemp food products including also cookies that were brought by one of the attendees...
