Tracing Vortex Clustering in a Superconductor by the Magnetic Flux Distribution.

By investigating spatial configurations of the intermediate mixed state in an intertype superconductor, it is shown that vortex clustering can be characterized by the sample averaged distribution of the penetrating magnetic field. The clustering is manifested in the two-peak structure of the distribution. The second peak indicates a spot a material occupies in the phase diagram of superconductivity types.

Blood Serum Zonulin in Colorectal Cancer, Autoimmune Bowel Diseases, and Irritable Bowel Syndrome.

Zonulin content in blood serum of patients with colorectal cancer (CRC; n=152; 30-84 years) and patients with large bowel adenomas (n=32; 39-82 years) was measured by standardized kit IDK Zonulin ELISA (Immundiagnostik AG). The healthy control group (n=50) comprised volunteers (27 women, 23 men; 25-68 years); pathological control group (n=84) - patients (55 women, 29 men;18-84 years) with irritable bowel syndrome (n=29), Crohn's disease (n=5), and ulcero-necrotic colitis (n=50). In comparison to healthy control group, the level of zonulin was significantly increased in CRC patients (p<0.

Helicobacter pylori infection: place of serological and cultural diagnostics in clinical guidelines.

The purpose of this work was to familiarize doctors with the methods and significance of serological and cultural diagnostics of H. pylori infection on the example of the test for diagnosing the state of the gastric mucosa «Gastropanel». Blood serum tests were performed for 1057 patients and 122 healthy people aged 18-64 years: pepsinogen I (PG I), pepsinogen II (PG II), gastrin-17 (G-17), basal/stimulated), antibodies (IgGHp) to H.

High SARS-CoV-2 load in the nasopharynx of patients with a mild form of COVID-19 is associated with clinical deterioration regardless of the hydroxychloroquine administration.

Because of the constantly growing numbers of COVID-19 infections and deaths, attempts were undertaken to find drugs with anti-SARS-CoV-2 activity among ones already approved for other pathologies. In the framework of such attempts, in a number of in vitro, as well as in vivo, models it was shown that hydroxychloroquine (HCQ) has an effect against SARS-CoV-2. While there were not enough clinical data to support the use of HCQ, several countries including Russia have included HCQ in treatment protocols for infected patients and for prophylaxis.

[Low Fermentable Oligo-, Di- and Monosaccharides and Polyols (FODMAP) diet in the treatment of patients with irritable bowel syndrome: basic principles and methodology].

Fermentable oligo-, di-, monosacc harides, and polyols (FODMAP) are a large class of small nondigestible carbohydrates, which are poorly absorbed in the small bowel. The microscopic size, high osmotic activity, and the higher fermentation of unabsorbed FODMAPs by colonic bacteria lead to bloating, abdominal pain, and flatulence in patients with irritable bowel syndrome. Therefore, low FODMAP diet appears to be promising treatment approach in the management of patients with irritable bowel syndrome (IBS).
