[A personalized approach to recurrent abdominal pain syndrome based on clinical and laboratory algorithms].

Objective: To optimize the diagnosis of abdominal pain syndrome occurring under the «mask» of acute pancreatitis via algorithms for clinical and laboratory examination.

Material And Methods: We have retrospectively and prospectively analyzed patients with abdominal pain syndrome. We selected all patients with acute pancreatitis who repeatedly applied with abdominal pain syndrome to polyclinics and hospitals between 2017 and 2021.

[Differential diagnosis of multiple sclerosis in children].

At the onset, multiple sclerosis (MS) in children is characterized by a phase of active inflammation with extensive demyelination of the white matter of the CNS, which often mimics this nosology with a whole spectrum of inflammatory demyelinating diseases such as ADEM, anti-MOG encephalitis, ONMSD. In order to formalize the diagnostic process, the International Pediatric Multiple Sclerosis Study Group (IPMSSG) proposed diagnostic criteria for the main immune-mediated demyelinating diseases of the CNS in children, which, in theory, should simplify the diagnostic search. However, in practice, the range of nosologies in the course of differential diagnosis is much wider and often it is not possible to establish an unambiguous diagnosis in the early stages.

[The results of an open comparative retrospective trial of the course of multiple sclerosis during treatment with infibeta and other interferon-beta bioanalogues and glatiramer acetate].

Aim: To evaluate the efficacy and safety of the interferon beta-1b bioanalogue 'infibeta' in the treatment of multiple sclerosis (MS) in comparison with other interferon beta bioanalogues and the generic drug glatiramer acetate.

Material And Methods: The data of 500 patients with MS treated with different disease-modifying drugs were analyzed. Patients of group 1 (n=95) received infibeta; group 2 (n=108) interferon beta-1b; group 3 (n=83) genfaxon-44; group 4 (n=109) sinnovex; group 5 (n=105) aksoglatiran FS.

[Comparative, placebo-controlled clinical study of efficacy and safety of glatiramer acetate 20 mg in patients with relapsing-remitting multiple sclerosis: results of the first year of the study].

Unlabelled: The article presents the results of international multicenter randomized double-blind, active and placebo-controlled, comparative phase 3 trial. The goal of the study was to demonstrate non-inferiority of BCD-063 (glatiramer acetate, manufactured by JSC «BIOCAD», Russia) to copaxone-Teva (Teva Pharmaceutical Enterprise Co., Ltd.

Synchronization phenomena in mixed media of passive, excitable, and oscillatory cells.

We study collective phenomena in highly heterogeneous cardiac cell culture and its models. A cardiac culture is a mixture of passive (fibroblasts), oscillatory (pacemakers), and excitable (myocytes) cells. There is also heterogeneity within each type of cell as well.
