PATHOLOGICAL BEHAVIORAL PATTERNS RELATED TO THE INTERNET IN A PERSON WHO USE PSYCHOACTIVE SUBSTANCES

The involvement of people who use psychoactive substances in Internet use imposes certain behavioral changes on them. The combination of thepsychopathological predispositional background in the form of emotional-volitional disorders with the phenomena inherent in the in-depth use ofthe Internet determines the development of specific behavioral patterns associated with Internet use in individuals of the studied group.The purpose of the study is to investigate and systematize pathological behavioral patterns associated with the Internet in people who use psychoactivesubstances.Material and research methods. To achieve the goal of the study, a content analysis of scientific literature and media materials was carried out, and 34 people with mental and behavioral disorders due to the use of psychoactive substances were examined (F19.2).As a result of the study, five pathological behavioral patterns associated with the Internet in individuals who use psychoactive substances were identified and described: reduction of offline communication and preference for online leisure, Internet coverage of one’s own asocial actions, change of addictive search activity from offline environment to the Internet, auto-induction of extreme drops moods with Internet content and Internet content inducing extreme behaviors.Conclusions. Internet use can lead to a specific pathological modification of the behavior of people who use psychoactive substances. Identified behavioral patterns can cause an increase in social maladaptation and act as a potentiating and supporting factor in anesthesia.

Two types of bone necrosis in the Middle Triassic Pistosaurus longaevus bones: the results of integrated studies

Avascular necrosis, diagnosed on the basis of either a specific pathological modification of the articular surfaces of bone or its radiologic appearance in vertebral centra, has been recognized in many Mesozoic marine reptiles as well as in present-day marine mammals. Its presence in the zoological and paleontologic record is usually associated with decompression syndrome, a disease that affects secondarily aquatic vertebrates that could dive. Bone necrosis can also be caused by infectious processes, but it differs in appearance from decompression syndrome-associated aseptic necrosis. Herein, we report evidence of septic necrosis in the proximal articular surface of the femur of a marine reptile, Pistosaurus longaevus , from the Middle Triassic of Poland and Germany. This is the oldest recognition of septic necrosis associated with septic arthritis in the fossil record so far, and the mineralogical composition of pathologically altered bone is described herein in detail. The occurrence of septic necrosis is contrasted with decompression syndrome-associated avascular necrosis, also described in Pistosaurus longaevus bone from Middle Triassic of Germany.

Safety of Beauveria bassiana (Bals.) Vuill. to Gallus domesticus L.

Beauveria bassiana, an important insect pathogen was used to evaluate its effect on the feeding, behavior, histology of the digestory system and anatomy of Gallus domesticus. The fungus (strain Unioeste 4) was administrated orally treated with chicken food. Chicken feces were collected, and the birds observed for 28 days. Also, were evaluated the weight of the birds, as well as any sign of intoxication or pathological modification. Tissue samples were withdrawn to test lesions with the optic microscope. There was 100% of survival of the birds, and no behavior alteration or external lesion was found. The test group presented the highest weight gain (1383.9±54.4g). Viable conidia were observed in the feces until 24 h after feeding the fungus, indicating that there was no germination inside the digestory system. No tissue lesion was observed, providing overwhelming evidence for the safety of B. bassiana to non-target organism G. domesticus.
