Introduction: Marijuana is one of the most widely used psychoactive substance. There is evidence of genetic predisposition for addiction.
Objective: The aim of the study is to evaluate personality traits measured by the NEO Five-Factor Inventory and State-Trait Anxiety Inventory, combined with analysis of rs1079597 and rs1800498 located in the gene.
Material And Methods: The study group consisted of 214 rural cannabinoid users and 301 controls. The same psychometric test and real-time PCR genotyping were performed in both studied groups.
Results: The values of Anxiety state, Anxiety trait, NEO FFI: Neuroticism and Openness in the rural cannabis using group were significantly higher than in the control group. On the other hand, lower values were observed among rural people using cannabis compared to the control group for NEO FFI: Extraversion, Agreeability and Conscientiousness. In the Anxiety trait subscale, a 2% association with the polymorphism rs1079597 was detected in subjects using cannabis. However, for the rs1800498, there was no effect on the differences in personality traits between rural cannabis users and the control group.
Conclusions: The study shows differences in personality traits between the cannabis using group and controls. Interaction between genetic factors and personality traits was also detected. The association showing the combination of psychological characteristics and genetic variants can bring us closer to the overall picture of the issue of marijuana addiction.

Multiple sclerosis (MS) is the most common cause of disability in young adults due to several motor, sensory, and cognitive symptoms. However, little is still known about the impact of psychological, cognitive, and social-support variables on subjective disability. This study is aimed at exploring the role of clinical, psychological, cognitive, and social-support variables in predicting disability levels as perceived by persons with multiple sclerosis (pwMS).

Objective: The Self-Discrepancies Scale (S-DS) is a multiple-subscore instrument designed to assess discrepancies between mental representations of the self: the actual self on one hand, and the ideal and socially prescribed selves on the other. Its idiographic subscores rely on the endorsement of self-descriptive traits, while its abstract subscores form an overall judgement of felt self-discrepancies. The objectives of the present study were to (i) evaluate the S-DS in a new non-clinical population, (ii) expand the body of data on the S-DS's convergent validity, (iii) study the idiographic data for the S-DS, and (iv) establish a nomothetic list of traits with a better choice of unwanted traits.

Introduction: Attitudes and beliefs guide our decision-making. In the educational context, prior research has noted the existence of prejudices and stereotypes among teachers that make it difficult to identify and care for gifted students. Stereotypes towards gifted students can hinder the identification and development of potential and the development of personality.

Religious beliefs can shape how people process fear. Yet the psychophysiological mechanisms underlying this phenomenon remain poorly understood. We investigated fear learning and extinction processes in a group of individuals who professed a belief in God, compared to non-believers.

Background: Prior studies have established correlations between gut microbiota (GM) dysbiosis, circulating metabolite alterations, and gastric cancer (GC) risk. However, the causal nature of these associations remains uncertain.
Methods: We utilized summary data from genome-wide association studies (GWAS) on GM (European, n=8,956), blood metabolites (European, n=120,241; East Asian, n=4,435), and GC (European, n=476,116; East Asian, n=167,122) to perform a bidirectional Mendelian randomization (MR) analysis, investigating the causal effects of GM and metabolites on GC risk.
