The features of the general equilibrium of usage of static models are estimated in the analysis of macroeconomic processes in post-socialist countries. The expediency of the use of these models for comparative analysis of impact scenarios for the fiscal and external economic policies on socio-economic development of Ukraine is grounded.

There has been rapidly increasing interest in psychedelics internationally in recent years, with decriminalisation of some substances in this class in the United States, establishment of research centres that focus on psychedelics, and expanded industry attention.Recent reviews have identified an emerging evidence base for psilocybin and other psychedelics in treatments for mental health conditions such as PTSD and treatment resistant depression Some drugs in this class have been designated by the US Food and Drug Administration as "breakthrough therapies" for these disorders and the Australian Government has recently dedicated 15 milliondollars toward clinical trials examining the treatment of mental illness with psychedelic drugs.In Australia, the National Drug Strategy Household Survey identified a small but significant increase in psychedelic use in the Australian general adult population, rising from 1 0 in 2016 to 1 6 in 2019 It should be noted that rates have been in a similar range across the past decade.One of the many potential reasons for the apparent increase in psychedelic use may be self treatment of mental health conditions The 2020 Global Drug Survey found almost 6 of their sample 6500 of 110000 reported self medicating with psychedelic drugs. In addition, there is increasing interest in microdosing that is, regular use of subthreshold doses of psychedelics with an aim to improve mood or cognition.In this bulletin we aimed to examine if there was any evidence of change in the use of psychedelic drugs among participants in the Ecstasy and Related Drugs Reporting System ( between 2010 and 2020 and if there was evidence for the very frequent use that would be suggestive of microdosing.

Abstract. The Xiaojiaqiao barrier lake, which was the second largest barrier lake formed by the Wenchuan Earthquake had seriously threatened the lives and property of the population downstream. The lake was finally dredged successfully on 7 June 2008. Because of the limited time available to conduct an inundation potential analysis and make an evacuation plan, barrier lake information extraction and real-time dam break flood simulation should be carried out quickly, integrating remote sensing and geographic information system (GIS) techniques with hydrologic/hydraulic analysis. In this paper, a technical framework and several key techniques for this real-time preliminary evacuation planning are introduced. An object-oriented method was used to extract hydrological information on the barrier lake from unmanned aerial vehicle (UAV) remote sensing images. The real-time flood routine was calculated by using shallow-water equations, which were solved by means of a finite volume scheme on multiblock structured grids. The results of the hydraulic computations are visualized and analyzed in a 3-D geographic information system for inundation potential analysis, and an emergency response plan is made. The results show that if either a full-break or a half-break situation had occurred for the Chapinghe barrier lake on 19 May 2008, then the Xiaoba Town region and the Sangzao Town region would have been affected, but the downstream towns would have been less influenced. Preliminary evacuation plans under different dam break situations can be effectively made using these methods.

Cancer is a key health issue across the world, causing substantial patient morbidity and mortality. Patient prognosis is tightly linked with metastatic dissemination of the disease to distant sites, with metastatic diseases accounting for a vast percentage of cancer patient mortality. While advances in this area have been made, the process of cancer metastasis and the factors governing cancer spread and establishment at secondary locations is still poorly understood. The current article summarizes recent progress in this area of research, both in the understanding of the underlying biological processes and in the therapeutic strategies for the management of metastasis. This review lists the disruption of E-cadherin and tight junctions, key signaling pathways, including urokinase type plasminogen activator (uPA), phosphatidylinositol 3-kinase/v-akt murine thymoma viral oncogene (PI3K/AKT), focal adhesion kinase (FAK), β-catenin/zinc finger E-box binding homeobox 1 (ZEB-1) and transforming growth factor beta (TGF-β), together with inactivation of activator protein-1 (AP-1) and suppression of matrix metalloproteinase-9 (MMP-9) activity as key targets and the use of phytochemicals, or natural products, such as those from Agaricus blazei, Albatrellus confluens, Cordyceps militaris, Ganoderma lucidum, Poria cocos and Silybum marianum, together with diet derived fatty acids gamma linolenic acid (GLA) and eicosapentanoic acid (EPA) and inhibitory compounds as useful approaches to target tissue invasion and metastasis as well as other hallmark areas of cancer. Together, these strategies could represent new, inexpensive, low toxicity strategies to aid in the management of cancer metastasis as well as having holistic effects against other cancer hallmarks.
