The use of cannabis for medicinal purposes dates back well before the era of modern medicine, but in recent years research into the use of medical cannabis in the medical and pharmaceutical sciences has grown significantly. In European countries, most cannabis plants have been and still are grown for industrial purposes. For this reason, hemp cultivation technology is relatively well researched, while little is known about the key factors affecting cannabis cultivation for medical purposes. The active substances of cannabis plant targeted by this review are called phytocannabinoids. The biosynthesis of phytocannabinoids is relatively well understood, but the specific environmental factors that influence the type and number of phytocannabinoids have been much less studied. Indoor or greenhouse cultivation, which uses automated lighting, ventilation, irrigation systems and complex plant nutrition has become much more sophisticated and appears to be the most effective method for producing medical cannabis. There are many different cultivation systems for cannabis plants, but one of the essential elements of the process is an optimal plant nutrition and selection of fertilisers to achieve it. This review summarises the existing knowledge about phytocannabinoid biosynthesis and the conditions suitable for growing plants as sources of medical cannabis. This review also attempts to delineate how nutrient type and bioavailability influences the synthesis and accumulation of specific phytocannabinoids based on contemporary knowledge of the topic.

Negative impact on the environment as a result of economic activity of man increasingly becomes the character of combined pollution of ecotoxicants, including xenobiotics of radiation and chemical nature. In animal husbandry in ecologically unfavorable regions, sorbtion-detoxication technologies based on the complex application of bioprotective substances of different origin are used to reduce the intake and accumulation of xenobiotics, to normalize the physiological state of animals and to obtain safe products. It is necessary to observe certain principles ensuring compatibility of components, a wide range of bioprotective action, efficiency and safety at their use in developing the compositions of such sorption-detoxifying complexes. The article substantiates the criteria that should be followed in creating sorption-detoxifying complexes and presents groups of drugs with different mechanisms of action (sorbents, antioxidants, immunomodulators, adaptogens and other biologically active substances) for inclusion in the formulations of combined compositions.

We have studied the possibility of increasing the production of young carp by applying a set of intensification measures and the introduction of innovative production methods, when growing it in artificial reservoirs. Works that has been carried out works provided with technology of cultivation of young fishes as one of the first stages of production of marketable products in aquaculture, secures the selection of qualitative and viable breeding material, providing it with appropriate environmental conditions for normal growth and development, search of optimum and balanced compound feeds which will supplement natural fodder base of ponds, and carrying out of complex measures concerning intensification of fish farming taking into account natural-climatic and geographical-zonal features of a separate economy. The main purpose of the work was to improve the technology of growing young fish in the carp farm of Ltd "Mykolaivska RMS" when using in the feeding of this year's granular feed. Generally accepted hydrochemical, hydrobiological and fish farming methods were used in order to achieve this goal. The technological features of growing carp fish planting material at low planting densities were studied in the ponds of the experimental fishery. The effect of land reclamation, fertilization of ponds to improve the natural feed base, feeding fish with granular feed with a well-balanced content of nutrients and biologically active substances, with constant control of temperature and hydrochemical regimes of ponds on morphometric parameters expediency of carrying out such measures in fisheries. Our research results indicate that the natural fodder basis of ponds of the experimental carp farm Ltd "Mykolaivska RMS" does not fully meet the regulatory conditions for growing young carp and carrying out the above set of intensification measures in combination with feeding young carp granular concentrated organic feed environmentally friendly and economically feasible.

The selection of the appropriate extraction method is crucial, especially for the receiving of active substances from plant material. The extraction using supercritical liquids and micellar-mediated extraction (MME) is the most advantageous among the alternative methods to classical solid–liquid extraction. However, the latter seems to be the best solution when the desired actives are polar. The following article presents a comprehensive review of the micellar-mediated extraction method in the last decade. The theoretical principle of the process was also refreshed and the current state of knowledge on the applications for analytical and manufacturing purposes was summarized.

The Impact

The ongoing care needed by children with chronic physical illness is a topic of national concern. The Pediatric Ambulatory Care Treatment Study (PACTS) is a classic pretest-posttest randomized experiment designed to evaluate a Pediatric Home Care (PHC) program in which an interdisciplinary team provides comprehensive primary health care, support, coordination, patient advocacy, and education to chronically ill children and their families. Home interviews were conducted by an independent research team with the 219 families at enrollment, 6 months, and 1 year; 80% completed all three interviews. Analyses indicate that pediatric home care is effective in improving the satisfaction of the family with care, in improving the child's psychological adjustment, and in lessening the psychiatric symptoms of the mother. The functional status of the children was equally well maintained in both groups, and there was no significant difference in the impact of the illness on the family between the two groups. There are indications that there may be a dose-related effect with respect to the child's psychological adjustment with those in the program for the longest period of time showing the greatest benefit. Such a home care program can be an effective intervention for minimizing the social and psychological consequences of chronic illness.

The benchmark dose (BMD) is the dose of a substance that is expected to result in a prespecified level of effect, the benchmark response level or BMR. It is a general approach to characterizing dose response, applicable to any toxicant and endpoint. A BMD is conceptually superior to a "no observed adverse effect level" (NOAEL) for this purpose because of being less determined by experimental design, because it is a precisely defined entity, and because its precision can be estimated. Since a BMD is a single number, just as an NOAEL, it is tempting to use the BMD as a straightforward replacement for the NOAEL in the assessment process for calculating allowable daily intakes. However, the level of toxic response at a NOAEL is unknown, while that at a BMD is well defined. Use of the BMD approach potentially adds consistency and objectivity to the process of deriving reference values (RfDs, RfCs, or ADIs) for setting regulatory levels. To take advantage of this, BMRs need to be selected in a consistent way across studies and endpoints. This paper discusses some issues affecting the selection of BMRs, and presents an example of a BMD calculated for the effects of peripubertal exposure to the fungicide vinclozolin.
