[Clinical and psychological features of people with internet dependence: experience of a pilot study].

Objective: The prevalence of Internet addiction (IA) is growing steadily, especially among the younger generation. The purpose of this multicenter study was to investigate the socio-demographic characteristics, clinical varieties, and profile of psychopathological symptoms of mental disorders in patients with IA.

Material And Methods: The study included 2 groups: the main group consisted of 44 people, aged 16 to 34 years, average age 22.

Characteristics of Artificial Immunogens Containing Peptide Mimotopes of HIV-1 Epitopes Recognized by Monoclonal Antibodies 2F5 and 2G12.

The paper describes construction of TBI-based recombinant proteins TBI-2F5 and TBI-2G12 that contain peptide mimotopes of HIV-1 epitopes recognized by broadly neutralizing antibodies 2F5 and 2G12, respectively. The capacity of the immunogens to induce neutralizing antibodies was evaluated. The sera of BALB/c mice immunized with recombinant proteins TBI, TBI-2F5, and TBI-2G12 neutralized HIV-1 env-pseudoviruses.

[Substances from pyrolised tissues of reptile carcases differently modulate immunity of mammals of both sexes].

Substances with gender action on immunity were detected in water soluble hydrolised matter from reptile carcases. The gender action was shown on isolated blood neutrophils, whole blood and in vivo by the antiviral activity on experimental animals, contaminated with three types of viruses: Herpes simplex type 1, the virus of encephalomyocarditis and the virus of hepatitis of mice. The possible mechanism of the inhibitory action on the male immunity was associated with the protein kinase cascade, including protein kinase C, activated by phorbolmyristate in the cells of the immune system.

[Stimforte action on the main inflammation characteristics in experimental animals contaminated by Herpes simplex-1].

In the brain and lungs of the experimental animals contaminated by Herpes simplex-1 there were detected much higher levels of the thiobarbituric acid-stained lipid oxidation products and proteolytic activity, evident of the inflammation process. Stimforte lowered the inflammation indices to the level, close to that in the brain of the noninfected animals. Yet the drug provided lower titers of the virus in the brain, lungs and serum in the contaminated animals and arrested the infection process by stimulation of the immune system.

[The impact of the antibody 2F5 biotinylation on the selection of the peptides from combinatorial phage library].

The impact of monoclonal antibodies (mAb) biotinylation on the output and the repertoire of selected peptides in the biopanning procedure were tested. A comparative analysis of the peptides selected from phage library using the biotinylated and non-biotinylated mAb 2F5 was performed. It was shown that the output of peptides homologous to the native epitope was 1.
