Abstract Background: Occupational exposures are among the common causes of respiratory diseases. Exposure to the natural fibers as cotton, hemp, flax, and jute can lead to some acute and chronic respiratory diseases among textile workers. One of the most important diseases related to natural fibers is byssinosis. This study was performed to assess and compare spirometric indices between textil...
Hemp bast fibers were degummed using combined microwave energy (MWE) and deep eutectic solvent (DES) to generate pure hemp cellulose for potential textile applications. The properties of the investigated compared with those alkali-treated several analytical techniques. Results revealed that fiber surface underwent dramatic structural disruption during pretreatment, due removal “gummy” compounds...
After having abolished the prohibition of the cultivation of the species Cannabis sativa L. (so-called fibre hemp) with minor content of the psychoactive Δ-tetrahydrocannabinol (THC), a wide variety of hemp food products is currently offered on the market. In this review, an introduction to the botany of the hemp plant and the current law situation in Germany and the European Union is presented...
Soil salinity is a serious threat to agriculture, because it compromises biomass production and plant productivity, by negatively affecting the vegetative growth and development of plants. Fiber crops like textile hemp (Cannabis sativa L.) are important natural resources that provide, sustainably, both cellulosic and woody fibers for industry. In this work, the response to salinity (200 mM NaCl...
The agricultural industry is one of the main economic contributors in developing countries, especially tropical regions. Extensive land clearing has led to severe erosion within watersheds, which increases vulnerability water catchments natural disasters, such as floods. Cellulosic fibers, jute, sisal, kenaf, hemp, and coir, are gaining increasing worldwide attention for their potential applica...
BACKGROUND Indian hemp has shown beneficial effects in various gastrointestinal conditions but it is not widely accepted due to high content of tetrahydrocannabinol resulting in unwanted psychotropic effects. AIM Since industrial hemp rich in cannabidiol lacks psychotropic effects the aim of research was to study the effects of industrial hemp on intestinal motility. MATERIALS AND METHODS A...
