Abstract
Olfactory dysfunction is an early marker of COVID-19 infection. However, individuals may develop chronic olfactory impairment for more than six months in 1-10 % of cases. The study's objective is to evaluate the efficacy and safety of intranasal immunotherapy using bioactive substances produced by M2 macrophages for the treatment of people with long-term post-COVID-19 hyposmia. Seven individuals with long-term persistent hyposmia (7 to 24 months), associated with PCR-confirmed coronavirus infection were evaluated for olfactory function at baseline, one, and six to twelve months after therapy. The intranasal inhalation of M2 macrophage conditioned medum (one time per day for 28-30 days) was well tolerated. Furthermore, olfactometry demonstrated that the patients restored their capacity to perceive (Kruskal-Wallis H test 14.123, p = 0.0009) and recognize odours (H = 11.674, p = 0.0029). In addition, the subjective evaluation of smell significantly improved (H = 11.935, p = 0.0026). At the 6- to 12-month follow-up, the majority of patients (5/7) reported extremely high levels of satisfaction with the outcomes, and the remaining two patients also felt generally positive about the therapy's success. Overall, our study showed that the use of intranasal inhalations as a method of delivering bioactive factors and the conditioned medium of M2 macrophages as a therapeutic agent are both safe, well tolerated and, according to preliminary data, clinically effective in the treatment of patients with long-term post-COVID-19 hyposmia.

Abstract
Driven by the growing threat of cancer, many research efforts are directed at developing new chemotherapeutic agents, where the central role is played by transition metal complexes. The proper ligand design serves as a key factor to unlock the anticancer potential of a particular metal center. Following a recent trend, we have prepared unsymmetrical pincer ligands that combine benzothiazole and thiocarbamate donor groups. These compounds are shown to readily undergo direct cyclopalladation, affording the target S,C,N-type Pd(II) pincer complexes both in solution and in the absence of a solvent. The solid-phase strategy provided the complexes in an efficient and ecologically friendly manner. The resulting palladacycles are fully characterized using nuclear magnetic resonance (NMR) and infrared (IR) spectroscopy and, in one case, by single-crystal X-ray diffraction (XRD). The solvent-free reactions are additionally analyzed by powder XRD. The pincer complexes exhibit remarkable cytotoxicity against several solid and blood cancer cell lines, including human colorectal carcinoma (HCT116), breast cancer (MCF7), prostate adenocarcinoma (PC3), chronic myelogenous leukemia (K562), multiple plasmacytoma (AMO1), and acute lymphoblastic leukemia (H9), with the dimethylamino-substituted derivative being particularly effective. The latter also induced an appreciable level of apoptosis in both parental and doxorubicin-resistant cells K562 and K562/iS9, vindicating the high anticancer potential of this type of palladacycles.

Abstract
Amino-functionalized phosphoryl compounds are among the most useful molecular scaffolds in medicinal chemistry, while the potential of their thiophosphorylated analogs, especially those having an alkylamino moiety, is still uncovered. This is mainly due to the lack of convenient synthetic routes to these organophosphorus derivatives. To address this issue, we have suggested the facile approaches to α-(aminomethyl)- and substituted/unsubstituted α-(aminobenzyl)diphenylphosphine sulfides based on either the sequential transformations of (hydroxymethyl)diphenylphosphine sulfide, with the Staudinger reaction of an azide derivative as the key stage, or the addition of Ph2P(S)H to hydrobenzamides followed by the acid hydrolysis. The compounds obtained were reacted with picolinyl chloride to yield functionalized amides which readily underwent direct cyclopalladation, resulting in new representatives of non-classical N-metalated Pd(II) pincer complexes. The latter exhibit promising cytotoxic activity against several human cancer cell lines and apoptosis inducing ability along with the remarkable cytotoxic effects on doxorubicin-resistant cell sublines.

Abstract
Platinum-based drugs are commonly recognized as a keystone in modern cancer chemotherapy. However, intrinsic and acquired resistance as well as serious side effects often caused by the traditional Pt(II) anticancer agents prompt a continuous search for more selective and efficient alternatives. Today, significant attention is paid to the compounds of other transition metals, in particular those of palladium. Recently, our research group has suggested functionalized carboxamides as a useful platform for the creation of cytotoxic Pd(II) pincer complexes. In this work, a robust picolinyl- or quinoline-carboxamide core was combined with a phosphoryl ancillary donor group to achieve hemilabile coordination capable of providing the required level of thermodynamic stability and kinetic lability of the ensuing Pd(II) complexes. Several cyclopalladated derivatives featuring either a bi- or tridentate pincer-type coordination mode of the deprotonated phosphoryl-functionalized amides were selectively synthesized and fully characterized using IR and NMR spectroscopy as well as X-ray crystallography. The preliminary evaluation of the anticancer potential of the resulting palladocycles revealed a strong dependence of their cytotoxic properties on the binding mode of the deprotonated amide ligands and demonstrated certain advantages of the pincer-type ligation.

Abstract
PURPOSE We use neural networks to evaluate and compare the spatial resolution of two different simulated monolithic PET detector elements. The effects of mixing events with single photoeffect interactions and multiple Compton scatterings are also studied. METHODS Two PET detector models were used in this study. The first one consisted of a LYSO crystal plate with 19.25 × 19.25 × 12 mm3 dimensions and 256-channel photomultiplier with parameters modeled after a Hamamatsu S-13615-1050N-16 SiPM. The second model used a larger LYSO crystal (57.6 × 57.6 × 12 mm3) and a 64-channel Sensl ARRAYC-60035-64P-PCB photomultiplier. A feed-forward neural network was used to reconstruct the point of 511 keV gamma interaction. The number of layers and the number of neurons per layer were varied. RESULTS The best resolution was achieved with the 57.6 × 57.6 mm2 detector model, with an average of 0.74 ± 0.01 mm for the XY plane and an average 1.01 ± 0.01 mm for the Z coordinate (depth of interaction). CONCLUSIONS Neural networks can be a powerful tool that can help to determine the optimal parameters for a design of an experimental device. This study demonstrates how neural networks can be used to evaluate the performance of two detector variants while not being dependent on specific signal and noise functions.

Abstract
Acute gastric necrosis is a rare event requiring organ resection. Delayed reconstruction is advisable in patients with peritonitis and sepsis. The most common complication of gastrectomy with reconstruction is failure of esophagojejunostomy and duodenal stump. In case of severe esophagojejunostomy failure, appropriate surgical approach and timing of reconstructive stage should be analyzed. We report one-stage reconstructive surgery in a patient with multiple fistulas after previous gastrectomy. Surgery included reconstructive jejunogastroplasty with jejunal graft interposition. The patient underwent previous several unsuccessful reconstructive procedures complicated by failure of esophagojejunostomy and duodenal stump with external intestinal, duodenal and esophageal fistulas. Nutritional insufficiency, water and electrolyte disorders due to significant loss of proteins and intestinal juice through the drain tubes deteriorated clinical status. Surgical procedures finished reconstruction, provided closure of multiple fistulas and stomas and restored physiological duodenal passage.

Abstract
A vast body of literature suggests a relationship between alcohol consumption and road traffic fatalities. Despite an impressive downward trend in road traffic fatalities in Russia, the death rate is still unacceptably high. Far fewer studies have differentiated the association by road users and types of alcoholic beverages. This population-based study aims to estimate the associations of total and beverage-specific alcohol per capita (15+) consumption (APC) based on official alcohol sales statistics and road traffic mortality using police data on the number of deaths by road users. The study covers the period 1965-2019. We employed a first-order difference linear regression model with robust and autocorrelation consistent standard errors, controlling for a level of motorisation. To examine the possible evolution of the phenomenon, we repeated models separately for three consecutive periods (1965-1984, 1985-2002, 2003-2019). The findings suggest that an annual 1-litre increase in APC (in litres of pure alcohol) associated with a corresponding increase in the death rates (per 100,000 inhabitants) of both unprotected road users and motor vehicle occupants by about 0.3 (p < 0.01) and 0.4 (p < 0.05), respectively. A beverage-specific analysis for 1965-2019 revealed a positive and significant association between mortality of pedestrians and cyclists and the consumption of strong alcoholic beverages (p < 0.05) as well as mortality of drivers and passengers and the consumption of weaker alcoholic beverages, primarily beer (p < 0.01). Various road safety strategies should be applied to prevent road traffic fatalities of road users.

Abstract
Amyloidosis was modeled in young mice by administration of aqueous solution of soy cream substitute and then, amyloidogenesis was corrected by oral administration of dry red wine. In mice with amyloidosis, the area of megakaryocytes decreased by 1.69 times, the relative content of oxyphilic forms of megakaryocytes increased by 4.33 times, and ploidy did not change in comparison with the corresponding parameters in intact mice. Administration of red dry grape wine against the background of formation of systemic amyloidosis changed the reaction of megakaryocytes: the content of polychromatophilic forms was comparable to the level of intact control, the content of oxyphilic forms decreased by 3.11 times, the RNA and DNA content in megakaryocyte nuclei decreased proportionally, and the ploidy decreased. Thus, red grape wine reduced the response of the megakaryocyte genome to the external supply of amyloidogenic substance.

Abstract
OBJECTIVE To analyze the mechanisms of non-occlusive mesenteric ischemia (NOMI) after digestive tract surgery. MATERIAL AND METHODS NOMI occurred in 10 (0.4%) patients after reconstructive digestive tract surgery between 2015 and 2021. There were 4 women and 6 men aged 29-92 years (67 [60; 71]). Patients differed from each other in the nature of baseline disease and surgical approach. All patients underwent standardized surgical interventions. There were no intraoperative complications. RESULTS Median of surgery time was 372.5 (246.25; 548.75) min, blood loss - 450 (200; 725) ml. These parameters conformed to the type of surgery. There were no specific clinical signs of NOMI. Lactic acidosis (>4 mmol/L) occurred in 7 patients after 1-3 postoperative days. In 6 patients, fulminant NOMI developed after 1-2 postoperative days with subsequent multiple organ failure syndrome and septic shock. All patients underwent emergency redo surgery. Multivisceral gastrointestinal necrosis occurred in 5 patients, gastric conduit necrosis - 3, colon necrosis - 1, gastric stump necrosis - 1 patient. Mortality rate was 80%. Two patients survived. CONCLUSION NOMI manifested as a septic shock in 60% of patients that was due to fulminant development of multivisceral necrosis after 1-2 postoperative days. Timely diagnosis of reversible NOMI in these cases was impossible. Extensive visceral necrosis in early postoperative period is probably associated with intraoperative critical ischemia of digestive organs.

Abstract
UNLABELLED The choice of medical rehabilitation in patients with anal incontinence is impossible without diagnostic data revealing the mechanism of fecal incontinence. The most promising are programs of comprehensive physiotherapeutic rehabilitation based on biofeedback training. The rate of anal incompetence (AI) after hemorrhoidectomy is 1.3-12.5%. However, in addition to the organic cause (surgical trauma), functional disorders of the external sphincter and pelvic floor muscles may contribute to the pathogenesis of anal incontinence, aggravating the incontinence symptoms after surgery. Therefore, these functional disorders should be diagnosed before surgery. However, medical rehabilitation programs for anal incontinence after hemorrhoidectomy are not standardized, and functional outcomes have not been studied. OBJECTIVE To evaluate the outcomes of comprehensive rehabilitation in patients with AI after hemorrhoidectomy to improve quality of life after surgery. MATERIALS AND METHODS A retrospective study was carried out on 46 patients (mean age 53.8±15.4 years) after hemorrhoidectomy with fecal incontinence, 13 (28.3%) males and 33 (71.7%) females. The main group included 25 patients who received comprehensive rehabilitation, including biofeedback training and tibial neuromodulation (TNM) for 15 days. The control group consisted of 21 patients who received TNM at home also for 15 days. The severity of fecal incontinence was determined using the Wexner score. The functional state of the sphincter before and after surgery was assessed using the anorectal manometry (sphincterometry) (WPM Solar, the Netherlands). RESULTS Comprehensive rehabilitation resulted in a statistically significant clinical improvement: a decrease in the Wexner score in both males and females. No significant differences in manometry results were observed: the anal sphincter tone increased by 16.0% in females and 10.6% in males, and contractility increased by 17.7% and 15.1%, respectively. Monotherapy with TNM in control group patients improved tone indices by 8.7% in females and 6.8% in males, and contractility by 6.2 and 5.4%, respectively, which was lower than in the main group. CONCLUSION Contraindications to physiotherapeutic procedures based on electrical stimulation, extracorporeal magnetic stimulation, and magnetic translumbosacral neuromodulation determine the only possible choice of medical rehabilitation, which is the combination of biofeedback training and TNM (as superior to TNM monotherapy). If out-patient medical rehabilitation is not feasible, patients are recommended to complement the home course with a specially designed set of exercises for anal incontinence treatment.

Abstract
The peculiarities of cyclopalladation of a series of non-classical pincer-type ligands based on monothiooxalyl amides bearing ancillary N- or S-donor groups in the amide units have been scrutinized both under conditions of conventional solution-based synthesis and in the absence of a solvent according to a solid-phase methodology including mechanochemical activation. Grinding the functionalized monothiooxamides with PdCl2(NCPh)2 in a mortar or vibration ball mill is shown to serve as an efficient and green alternative to the synthesis of these complex metal-organic systems in solution that can offer such advantages as the absence of any auxiliary and significant rate and yield enhancement, especially for the challenging ligands. The realization of S,N,N- or S,N,S-monoanionic tridentate coordination in the resulting pincer complexes has been confirmed by multinuclear NMR (including 2D NMR) and IR spectroscopy and, in some cases, X-ray diffraction. The course and outcome of the solid-phase reactions have been studied by a combination of different spectroscopic methods as well as SEM/EDS analysis. The preliminary evaluation of cytotoxic activity against several human cancer cell lines has revealed the high potency of some of the cyclopalladated derivatives obtained, rendering further development of solvent-free synthetic routes to this type of complexes very urgent.

Abstract
In the search for potential new metal-based antitumor agents, two series of nonclassical palladium(II) pincer complexes based on functionalized amides with S-modified cysteine and homocysteine residues have been prepared and fully characterized by 1D and 2D NMR (1H, 13C, COSY, HMQC or HSQC, 1H-13C, and 1H-15N HMBC) and IR spectroscopy and, in some cases, X-ray diffraction. Most of the resulting complexes exhibit a high level of cytotoxic activity against several human cancer cell lines, including colon (HCT116), breast (MCF7), and prostate (PC3) cancers. Some of the compounds under consideration are also efficient in both native and doxorubicin-resistant transformed breast cells HBL100, suggesting the prospects for the creation of therapeutic agents based on the related compounds that would be able to overcome drug resistance. An analysis of different aspects of their biological effects on living cells has revealed a remarkable ability of the S-modified derivatives to induce cell apoptosis and efficient cellular uptake of their fluorescein-conjugated counterpart, confirming the high anticancer potential of Pd(II) pincer complexes derived from functionalized amides with S-donor amino acid pendant arms.

Abstract
UNLABELLED Surgical treatment of rectal cancer and sphincter-preserving low anterior resection results to evacuation disorders («low anterior resection syndrome» - LARS). There are no clinical recommendations for the treatment of patients with LARS as well as a rehabilitation program for them. OBJECTIVE To develop a rehabilitation program for patients with low anterior resection syndrome. MATERIAL AND METHODS The investigation was performed at 2 stages. During the first stage, 29 patients with LARS (17 (58.6%) men, mean age of the participants' 61.5±9.5 years), 12 (41.4%) women (mean age 61.2±7.8 years) were examined and received the course of conservative treatment with the use of biofeedback-therapy performed by the standard protocol. On the second stage, 17 patients (mean age 61.4±12.7 years) - 9 (52.9%) men, 8 (47.1%) women received biofeedback therapy in combination with tibial neuromodulation (TNM). Functional state of the rectum and the locking apparatus in all patients were evaluated by anorectal manometry: sphincterometry and studies of the reservoir function of the rectum before and after treatment. RESULTS The developed complex of rehabilitation measures led to improved treatment results for patients with rectal cancer by improving the quality of life after low anterior resection, reducing the manifestations of LARS (by 47.8%). Stable positive results of treatment were maintained in 36.4% of patients, positive dynamics from the treatment according to the LARS scale decreased slightly in 54.5%, deterioration of indicators in 3-6 months after conservative rehabilitation was registered in 9.1% of cases. At the first stage maximal squeeze pressure improvement was reached in the whole cohort (p=0.047), at the second stage these trend was seen only for women for the pressure values at rest (p=0.01) and during squeeze (p=0.025). The data obtained allowed us to recommend a repeat course of treatment to 63.6% of patients. The authors modified and optimized a special complex of physical therapy for the rehabilitation of patients both in a medical institution and at home. These exercises are aimed at improving the functional state of the pelvic floor muscles and sphincter apparatus. CONCLUSION Rehabilitation program for patients with low anterior resection syndrome should include: 1) biofeedback therapy to improve the holding function; 2) biofeedback therapy aimed at improving the reservoir function and sensitivity of the rectum to filling; 3) tibial neuromodulation. This program may help improving the contractility of the anal sphincter and reservoir function of the rectum, as well as the appearance of the urge to defecate.

Abstract
OBJECTIVE To formulate the concept of physiological reconstruction of the digestive tract during redo gastric surgery. MATERIAL AND METHODS There were 52 patients who underwent redo gastric surgery after previous resections, drainage and antireflux procedures in 2011-2017 at the Vishnevsky National Research Surgical Center. Redo resection of the stomach with Billroth-1 and Hofmeister reconstructions were performed in 5 (9.6%) and 1 patient (1.9%), respectively. Roux-en-Y reconstruction was performed in 4 (7.7%) patients after gastric remnant extirpation. Jejunogastroplasty was used in 30 (57.7%) patients. A segment of the transverse colon as the reconstructive material was used in 2 (3.8%) patients, left colon - in 8 (15.4%) after esophagectomy. One (1.9%) patient underwent extirpation of 'small' stomach and thoracic esophagus after previous gastric bypass. Gastric remnant was used as an isoperistaltic tube for subtotal esophagoplasty. Reconstruction was not possible in only 1 (1.9%) patient after advanced visceral resection for recurrent cancer within esophagojejunostomy due to deficit of visceral material. RESULTS Postoperative complications were observed in 5 (9.6%) patients. Partial failure of esophagojejunostomy and duodenojejunostomy occurred in 2 (3.8%) and 1 patient (1.9%), respectively. Colon transplant necrosis was noted in 1 (1.9%) patient that required resection followed by colo- and esophagostomy nutrition. One patient died on the 1st postoperative day from progressive multiple organ failure. At the end of the study, 44 (86.2%) out of 51 patients were under follow-up. Good results were revealed in 26 (59.9%) patients, satisfactory outcomes - in 12 (27.4%) patients. Redo surgery was not effective in only 6 (13.7%) patients. CONCLUSION Evaluation of our results demonstrates complete alleviation of pathological postoperative syndromes after gastric surgery in the majority of patients. Therefore, redo surgery with gastroplasty and restoration of duodenal passage are advisable.

Abstract
We studied the response of mast cells in mouse liver to experimental amyloidosis modeled by administration of aqueous solution of soy cream substitute and its correction by spontaneous dry red wine intake per os. Mast cells in mice with amyloidosis and intact mice were presented by α-ortho- and β1-metachromatic non-degranulating forms. In mice with amyloidosis, the relative content of β1-metachromatic mast cells in the capsule and parenchyma of the liver was by 1.8 and 1.5 times higher than in intact animals, respectively. In mice with amyloidosis receiving dry red wine, the proportions of mast cells with different degrees of metachromasy and degranulation were similar to those in intact mice, but the relative content of β1-metachromatic mast cells in the liver parenchyma in these animals was by 1.6 times higher than in intact mice. Therefore, mast cells respond to amyloidosis development by changes in both the metachromasy and degranulation degree; dry red wine can be considered as a factor of amyloidosis prevention.

Abstract
The swelling of a polymer ion-exchange membrane Nafion in water with various heavy isotope contents (D2O) was studied by photoluminescent UV spectroscopy. The photoluminescence arises because of the presence of sulfonic groups attached to the ends of the perfluorovinyl ether groups that form the tetrafluoroethylene (Teflon) backbone of Nafion. The width of the colloidal region, which is formed near the membrane surface as a result of the outgrowth of Nafion microfibers toward the bulk liquid, varies non-monotonically with D2O content, displaying a narrow maximum in the low concentration region. A significant insight into the unexpected isotopic effects revealed in swelling Nafion in deuterated water is provided. Mainly, the polymer swelling is very sensitive to small changes (on the order of several tens of parts per million) in the content of deuterium, which, for instance, can help in understanding the isotopic effects in living tissues.

Abstract
AIM The aim of the present study was to investigate the connection of sleep disorders (SD) with a headache (HA) among the representative sample of population. MATERIAL AND METHODS 1115 inhabitants of Chuvashia (491 men and 624 women) aged from 18 to 70 years old have been interviewed (middle age 38.7±13.9 years old); respondents under 18 and over 70 years old were not included into the research. There were 690 city residents, and 425 residents of the rural areas. The questionnaire approved earlier in the research of HA, and also the questions directed to identification of SD were used. One-way ANOVA, Chi-square test were used to compare variables of the groups. RESULTS There were 718 (64.4%) respondents with SD and HA (the main group), 366 (23.8%) with HA without SD (comparative group), 16 (1.4%) with SD without HA, and 15 (1.3%) without SD and HA. The main group of the respondents authentically differed from other groups in older age, a larger number of women and villagers, presence of concomitant diseases in them. In the respondents with SD arose more often, pain had the combined (polymorphic) character, HA were more severe, localized in several areas of the head, but were of smaller duration. Among them there were more people with short sleep duration (<5 hours of night dream) and accepting sedative-hypnotic medications. HA without SD had a pricking character more often; the respondents more often slept in the afternoon, differed in higher level of education, and a rarer occurrence of cases of the increased arterial pressure. CONCLUSION SD are often connected with HA, with their frequency, expressiveness and localization. Development of SD from HA are influenced by existence of concomitant diseases, age, gender and the place a residence. SD make the current of HA more severe.

Abstract
Early diagnosis of congenital glaucoma allows surgery to be performed at the stage of reversible glaucomatous alterations of the optic disc and retina. In primary congenital glaucoma, the main reason for visual acuity reduction following surgical stabilization of the intraocular pressure are corneal changes. These include an increased corneal diameter, Haab's striae, areas of thickening and a greater posterior elevation. The resultant irregular astigmatism leads to amblyopia and a marked decrease in visual acuity. Active pleoptic treatment started from a very early age in children operated on for compensated congenital glaucoma provides them an opportunity to achieve high visual acuity and full rehabilitation.

Abstract
Cucurbit[7]uril (CB7) is an uncharged and water-soluble macrocyclic host. CB7 binds to doubly protonated tuftsin, which is the tetrapeptide Thr-Lys-Pro-Arg, with moderate affinity (Ka=2.1×103M-1). In this study, the host-guest complexation was confirmed by fluorescence titration. This affinity would allow for easy release of the peptide under physiological conditions. According to density functional theory calculations, the structural binding motif involves hydrogen bonding. The most energetically stable form had the Arg side chain inside the CB7 cavity. The effects of the tuftsin-CB7 complex on the proliferation and cytokine activity of immune cells were studied. The complex had broader spectrum immunomodulation than free peptides, and caused statistically significant (p<0,05) changes in cytokine production (tumor necrosis factor-α, interleukin-2, interferon-γ, and interleukin-10) by mononuclear cells. By contrast, the free peptide only activated tumor necrosis factor-α production.

Abstract
Subcutaneous daily injection (with neglect of aseptics) of 0.5 ml solution of soybean cream substitute (10% volume in distilled water) during 30 days caused systemic amyloidosis in 30-day-old mice. All the known methods for induction of systemic amyloidosis are based on the use of old animals, as senile tissue bradytrophy allows effective simulation of amyloidosis.

Abstract
We analyzed telomere length of individual chromosomes in peripheral blood lymphocytes of healthy individuals and patients with rheumatoid arthritis. Quantitative fluorescent in situ hybridization and subsequent computer analysis of metaphase chromosomes showed that distribution of telomere length on individual chromosomes is different under normal and pathological conditions. Patients with rheumatoid arthritis had significantly shorter chromosome 4p telomeres, which can be essential for pathogenesis of this multifactorial disease. Additionally, disease activity inversely correlated with telomere length on chromosome 10p carrying genes involved in T cell differentiation and proliferation.

Abstract
The spectrum of alternatively spliced IL-4 and IL-6 gene mRNA was studied in peripheral blood mononuclears from healthy donors and in human fetal tissues. It was found that the expression of alternatively spliced IL-4 and IL-6 gene mRNA in fetal tissues is tissue specific and that hemopoiesis- and immunopoiesis-related tissues differ by the amount of IL-4 and IL-4δ2 mRNA. An mRNA variant IL-4alt3 carrying partial exon 3 deletion was for the first time identified in human mononuclear cells.

Abstract
AIM To determine the possible boundaries of high-dose immunosuppressive therapy and autologous hematopoietic stem cell transplantation (HDIT-autoHSCT) for autoimmune diseases (AUDs), such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS). SUBJECTS AND METHODS A long-term trial was conducted at one center to evaluate the efficiency and safety of HDIT-autoHSCT in patients with AUDs. The previous standard therapy was noted to be resistant or lowly effective. The age of 10 patients with systemic connective tissue diseases was 27.6±2.8 years; the pre-HDIT-autoHSCT disease duration was 5.9±1.3 years; the median posttransplantation follow-up was 39.3 months. The age of 49 patients with MS reached 34.9±1.33 years; the pretransplantation disease duration was 8.4±0.69 years; the median post-HDIT-autoHSCT follow-up was 42 months. The efficiency of transplantation was evaluated on the basis of clinical findings, by using scales, laboratory tests, and magnetic resonance imaging. Pretransplantation conditioning was carried out according to the protocols: a) BEAM + antilymphocyte globulin (ALG); b) fludarabine + melphalan + ALG. No fatal outcomes due to a transplant procedure were observed. RESULTS Overall 5-year survival after transplantation was 80% for systemic connective tissue diseases and 95% for MS; 5-year progression-free survival rates were 30% in the RA and SLE groups and 45% in the MS group. HDIT-autoHSCT turned out safe and reduced the activity of the process and further disease progression for a long period of time, as confirmed by regression of clinical symptoms and/or status stabilization in 9 patients with SLE or RA and in all patients with MS. CONCLUSION The favorable factors associated with the results of transplantation are age younger than 35 years in collagenoses with their short-term duration and moderate signs; age younger than 40 years in MS with a disease duration of less than 10 years and expanded disability status scale scores of not more than 6.5. Of importance are functional system scores, duration of first remission, and an index of disease progression in different types of MS.

Abstract
We studied safety and clinical efficacy of transplantation of autologous bone marrow cell in complex therapy of 158 patients with chronic hepatitis and cirrhosis of the liver. The efficiency of cell therapy was assessed in 12 months after single injection of the cells. The positive response (alleviation of liver cirrhosis or stabilization of the pathological process) was observed in 70% cases. The efficacy of therapy correlated with the severity and etiology of the disease and was maximum in patients with Child-Pugh class A (in 82.5% cases) and class B liver cirrhosis (in 79% cases); in patients with class C liver cirrhosis, the positive response was achieved in 42.5% cases. In 39 patients, ultrasonic examination performed in 3 years after transplantation revealed no focal lesions or ectopic ossification foci.

Abstract
There are numerous data in experimental and clinical medicine that convincing evidence on the leading role of the immune system in the pathogenesis of tumor diseases. Exactly immune cells such as cytotoxic T lymphocytes, NK cells, macrophages and dendritic cells have the ability to kill tumor cells. Under normal conditions the activity of these cells is a factor of inhibition proliferation and differentiation of tumor cells. An appearance of tumor itself, as uncontrolled cell growth and clinical manifestation, says that it was changed the cytotoxic activity of the cells causing tumor immunity. The main factor, if not the only reason for the decline of anti-tumor activity of the cells, is the formation of powerful extra- and inside-tumor suppressor mechanisms suppressing cytotoxic activity of anti-tumor immune-competent cells and allowing tumor cells to avoid surveillance by the immune system. It is showed that T and B cells, macrophages, and cells of myeloid origin suppressors possess these immunosuppressive properties. Therefore, in the future, methods to suppress functional activity of cells suppressors of various geneses can be the basis for immunotherapy of tumor growth.

Abstract
The influence of pH on the distribution of metal cations [Cd(II), Cu(II), Fe(II), Ni(II), Zn(II)] in a four-component heterophase system (H2O-H2SO4-MSO4-cellulose sorbent) was studied. Protodesorption of metal cations was studied with indicator and constant quantities of [MSO4] salts and constant solvent-sorbent ratio. Linear dependence lgКDМ2+=f(рН) with tgα=1/2 of the КDМ2+ metal ions distribution coefficients from the acidity of the aqueous phase is observed in logarithmic coordinates. Depression of the exponent corresponding to proton involvement in protodesorption from 2 (theory) to 0.5 (experiment) indicates that anions of the aqueous phase are involved in the process of exchange of metal cation for proton on the anionic centers of the sorbent, which corresponds to participation of the salt and acid components of the system in molecular non-dissociated form in an equivalent proportion H2SO4/MSO4=1/1. Different behavior of the salt and acid components in ion exchange of cations for cations and cations for protons is due to the differences in the constraint coefficients of their molecular and ionic forms which must be taken into consideration in equations describing thermodynamics of the interphase exchange.

Abstract
The objective of the present study was the retrospective analysis of the materials collected by the Republican Bureau of Forensic Medical Expertise, Ministry of Health and Social Development of Chuvash Republic, during the period from 1997 till 2002 for the elucidation of the chronological patterns of sudden cardiac death (SCD) associated with alcohol consumption depending on the sex and age of the victims, days of the week and months of the year as well as weather conditions. It was shown that the peak of mortality among men and women taking no alcohol fell on Monday. It was highest in May and decreased by February. The alcohol consumption significantly changes the chronological patterns of mortality from cardiovascular pathology. It was highest among the women abusing alcohol in August and October. The study has demonstrated a weak negative correlation between the frequency of sudden cardiac death among non-consumers of alcohol and dew-point temperature among the persons having alcohol in blood.

Abstract
BACKGROUND At the development of graft versus host disease in genetically homogeneous population of (C57BI/6 x DBA/2) Fl mice two clinical phenotypes of SLE-like disease were revealed: lupus+ (immune complex glomerulonephritis and hemnolytic anemia) and lupus - (hemolytic anemia). The GvHD phenotypic heterogeneity is determined by the Th2-polarization: Th2 lymphocyte predominant activity, leads to the lupus+development, or prevalence activity of Th1 cells, leads to the lupus- development. OBJECTIVE Our aim was to evaluate the possibility of using an experimental model of autoimmnune disease for studying and testing of epigenetic modifications, shifting Th1/Th2 balance in vivo. METHODS Chronic GVHD was induced in B6D2F1 mice by the transplantation of 130x10(6) parental DBA/2 splenocytes. Anti-ds-DNA, total IgG and IgGI, IgG2a Abs were measured by ELISA. RESULTS Six- to 8-week-old female DBA/2 and B6D2F1 mice were obtained from Biological Research Laboratory (Novosibirsk). It was established that regular moderate physical activity (unladed swimming) shifted Th1/Th2 balance towards Th1. This leads to a decrease in a population of recipients the lupus+ mice from 57 to 26% (p <0,001) with significantly reduced hypergammaglobulinemia (IgG from 2,8 to 2,0 mg/ml; p <0,047) and DNA antibodies titer from 0,18 to 0,12 OD (p =0,05). Administration of epigenetic modificator bisphenol A at low doses, which mimicking estrogen effects, enhances the proportion of lupus+ mice in experimental groups from 33 to 64% (p <0,001) and impairs their clinical status by the increasing the urine protein level from 2.8 to 4,2 mg/ml (p <0,001) in animals. CONCLUSION Th1/Th2 - balance presumably is determined by the immune system epigenetic modification in experimental mice, formed on the previous stages of ontogeny and defines the direction of immune processes development in individual animal.

Abstract
Considered natural and experimental amyloidosis models in the existing theories context and known amyloidogenesis mechanisms. Available clinical and experimental observations indicate that the opinion of a fatal incurable amyloidosis wrong. It is shown that there is a significant amount of experimental easily replicable amyloidosis models, which may be used for practicing the treatment methods of this pathology. We offer an amyloidosis models classification: natural (animal models with generic amyloidosis), cell clones, artificial (infectious, protein, etc.). Based on the analysis of amyloidosis existing models concluded--none of the accepted in the scientific the theories community for amyloid building does not combine or explains all known facts about the amyloidogenesis mechanisms. It is assumed that there is a proteins group, the beta-sheet structure, which are potentially capable of amyloid conformation building. It is assumed that beta-sheets of these proteins have similar amino acid composition. The condition for the amyloid building conformation is getting too much protein in sufficient quantities in an uncharacteristic place where the ionic strength of the tissue fluid is such that it promotes the amyloid building conformation. It is assumed that an unfortunate amount of ionic strength environment amyloid protein is provided by polysaccharides, tubulins proteins and ionized silicon.

Abstract
As it became known recently, in addition to the enzyme (enzymes and/or ribozymes) in living organisms occur a large number of ordinary chemical reactions without the participation of biological catalysts. These reactions are distinguished by low speed and, as a rule, the irreversibility. For example, along with diabetes mellitus, glycation and fructosilation of proteins are observed resulted in posttranslational modification with the low- or nonfunctioning protein formation which is poorly exposed to enzymatic proteolysis and therefore accumulates in the body. In addition, the known processes such as the nonenzymatic carbomoylation, pyridoxylation and thiamiation proteins. There is a reasonable basis to believe that alcoholic injury also realized through parametabolic secondary metabolites synthesis such as acetaldehyde. At the same time, the progress in supramolecular chemistry proves that in biological objects there is another large group ofparametabolic reactions caused by the formation of supramolecular complexes. Obviously, known parameterizes interactions can modify the formation of supramolecular complexes in living objects. These processes are of considerable interest for fundamental biology and fundamental and practical medicine, but they remain unexplored due to a lack of awareness of a wide range of researchers.
