This paper is devoted to the description of spessartine-almandine garnet (Sps: 39.8-60.2%; Alm: 29.1-56.76%; Grs <7%, Prp <3.6%, Adr <5%) from aplitic dyke rocks of the Mórágy granitoid near Erdõsmecske and Aranyos valley. The aplitic dyke rocks contain K-feldspar, plagioclase, quartz, (myrmekite), ±garnet, ±biotite, chlorite or secondary muscovite, ±ore minerals, ±calcite, ±apatite and ±epidote. Two different zoning types in garnet were detected by electron microprobe. Zoning type I means either Mn enrichment at the expense of Fe towards the rim or towards the core or plateau garnet profiles. Zoning type II displays Ca enrichment at the rim of garnet. A high proportion of Sps component in garnet and the character of zoning type I are considered as typical magmatic features. The pressure-temperature estimation for aplite formation arises from experimental investigations of Green (1977) in agreement with the hypothetical approach of liquidus relationships by Abott and Clarke (1979) giving a minimum temperature estimation of c. 675 °C-700 °C at pressure of 1-3 kbar. Following the magmatic crystallization, solid state deformation is evidenced by dynamic recrystallization of quartz and feldspars at temperatures of about 450-500 °C in the upper greenschist to lower amphibolite facies. Grossular-rich rim of garnet indicates pressure increase during ductile deformation.

Whole body nitrogen has been measured absolutely in male volunteers and patients by in-vivo neutron activation analysis using
whole body hydrogen as an internal standard. The 10.8 MeV and 2.2 MeV prompt gamma rays from nitrogen and hydrogen respectively
give a result reproducible to 4% for a dose of 100 mRem. Whole body potassium measured by whole body counting natural40K and whole body nitrogen have been correlated in normal adult males and patients. In the normals the correlation coefficient
was 0.96 with coefficient of variation 4%. In the patients these parameters were 0.92 and 8% in 140 measurements. The ratio
of N/K increased significantly as the degree of clinical wasting progressed.

The effect of feeding different levels (10 and 20%) of dehydrated olive cake pulp on certain blood parameters and on the catalytic activity of serum enzymes was studied in fattening rabbits. A total of 60 rabbits were divided into a control group (C) and two experimental groups (E1, E2), each comprising 10 males and 10 females. Rabbits of Group C received no dehydrated olive cake pulp in their diet, while rabbits of Group E1and Group E2were fed 10% and 20% dehydrated olive cake pulp, respectively. After Day 56 of the experiment, blood samples were obtained by cardiac puncture and certain blood parameters as well as the catalytic activity of serum enzymes were determined. Following the experimental feeding period no significant differences were found between Group C and Groups E1and E2in red blood cell (RBC) and white blood cell (WBC) count, haemoglobin concentration and haematocrit value. Similarly, after 56 days of experimental fattening no significant differences were found between the control group and the experimental groups in the catalytic activity of the serum enzymes alkaline phosphatase (AP), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), and lactate dehydrogenase (LDH). However, Group E2 rabbits manifested a significantly higher alanine aminotransferase (ALT) activity in the serum than did rabbits of Group E1. The results indicate that the inclusion of dehydrated olive cake pulp in the diet at the rate of 10% or 20% caused no changes in the investigated blood parameters and serum enzyme activities of fattening rabbits.

Prometryne is a methylthio-s-triazine herbicide used to control annual broadleaf and grass weeds in many cultivated plants. Significant traces are documented in environment, mainly water, soil and plants used for human and domestic animal nutrition. Data on the toxic effects of prometryne and other methylthios-triazine have scorcely been published. The goal of this study was to investigate if prometryne, applied orally, could induce DNA damage in mouse leukocytes, in subchronical
experimental design. Three different doses of prometryne were applied
repeatedly every 48 hours. After the 7th dose (day 14) and the 14th dose (day 28) blood leucocytes were analyzed by alkaline Single Cell Gel Electrophoresis (Comet) assay. The results of three different comet parameters showed general increase in Olive tail moment, tail length and tail intensity values in treated groups of animals. The increase in measured values was almost proportional to the dose received and the time of exposure. We conclude that prometryne or its metabolic residues have the potential to induce processes that cause genotoxic effects on leukocytes on mice in

The current study explored the nature of problematic (addictive) video gaming (PVG) and the association with game type, psychosocial health, and substance use.
Data were collected using a paper and pencil survey in the classroom setting. Three samples were aggregated to achieve a total sample of 8478 unique adolescents. Scales included measures of game use, game type, the Video game Addiction Test (VAT), depressive mood, negative self-esteem, loneliness, social anxiety, education performance, and use of cannabis, alcohol and nicotine (smoking).
Findings confirmed problematic gaming is most common amongst adolescent gamers who play multiplayer online games. Boys (60%) were more likely to play online games than girls (14%) and problematic gamers were more likely to be boys (5%) than girls (1%). High problematic gamers showed higher scores on depressive mood, loneliness, social anxiety, negative self-esteem, and self-reported lower school performance. Nicotine, alcohol, and cannabis using boys were almost twice more likely to report high PVG than non-users.
It appears that online gaming in general is not necessarily associated with problems. However, problematic gamers do seem to play online games more often, and a small subgroup of gamers — specifically boys — showed lower psychosocial functioning and lower grades. Moreover, associations with alcohol, nicotine, and cannabis use are found. It would appear that problematic gaming is an undesirable problem for a small subgroup of gamers. The findings encourage further exploration of the role of psychoactive substance use in problematic gaming.
