Abstract
Soft tissue sarcomas are aggressive mesenchymal-origin malignancies. Undifferentiated pleomorphic sarcoma (UPS) belongs to the aggressive, high-grade, and least characterized sarcoma subtype, affecting multiple tissues and metastasizing to many organs. The treatment of localized UPS includes surgery in combination with radiation therapy. Metastatic forms are treated with chemotherapy. Immunotherapy is a promising treatment modality for many cancers. However, the development of immunotherapy for UPS is limited due to its heterogeneity, antigenic landscape variation, lower infiltration with immune cells, and a limited number of established patient-derived UPS cell lines for preclinical research. In this study, we established and characterized a novel patient-derived UPS cell line, JBT19. The JBT19 cells express PD-L1 and collagen, a ligand of the immune checkpoint molecule LAIR-1. JBT19 cells can form spheroids in vitro and solid tumors in immunodeficient nude mice. We found JBT19 cells induce expansion of JBT19-reactive autologous and allogeneic NK, T, and NKT-like cells, and the reactivity of the expanded cells was associated with cytotoxic impact on JBT19 cells. The PD-1 and LAIR-1 ligand-expressing JBT19 cells show ex vivo immunogenicity and effective in vivo xenoengraftment properties that can offer a unique resource in the preclinical research developing novel immunotherapeutic interventions in the treatment of UPS.

Abstract
BACKGROUND This work summarizes our experience with WT1 monitoring before and after allogeneic hematopoietic stem cell transplantation (allo-HSCT). PATIENTS AND METHODS The expression of WT1 gene was measured by real-time polymerase chain reaction in peripheral blood according to the European Leukemia Net recommendations. Between May 2005 and August 2019, we analyzed 147 consecutive patients with acute myeloid leukemia with high WT1 expression at diagnosis, transplanted in first (CR1) or second (CR2) complete remission. RESULTS At the time of allo-HSCT, 107 patients had WT1-normal expression (WT1 ≤ 50 copies), and 40 patients had WT1-high expression. The median follow-up was 21 months. The estimated 5-year overall survival and event-free survival was significantly better in the WT1-normal cohort (65% and 57% vs. 37% and 25%; P = .0003 and P < .0001, respectively) and 5-year cumulative incidence of relapse was significantly lower in the WT1-normal group (19% vs. 53%; P < .0001). Five-year non-relapse mortality was not significantly different (20% and 23%). Multivariate analysis revealed WT1-high expression and acute graft-versus-host disease grade 3/4 as significantly negative prognostic factors for OS. Overall, 49 patients developed WT1 molecular relapse in the post-transplant period; in 14 cases, the therapeutic intervention was done. In all but 1 relapsed patient where WT1 minimal residual disease (MRD) was monitored (38 patients), we detected WT1-high levels (sensitivity of 97%). CONCLUSION The results of the analysis confirmed our previous experience that WT1 status before allo-HSCT is a strong prognostic factor for both OS and relapse risk. In addition, we confirmed the usefulness of this marker for MRD monitoring after allo-HSCT. The main advantage is the possibility of frequent MRD monitoring in peripheral blood and early bone marrow examination based on WT1-high expression.

Abstract
The purpose of this study was to create an open access repository of validated liquid chromatography tandem mass spectrometry (LC‐MS/MS) multiple reaction monitoring (MRM) methods for quantifying 284 important proteins associated with drug absorption, distribution, metabolism, and excretion (ADME). Various in silico and experimental approaches were used to select surrogate peptides and optimize instrument parameters for LC‐MS/MS quantification of the selected proteins. The final methods were uploaded to an online public database (QPrOmics; www.qpromics.uw.edu/qpromics/assay/), which provides essential information for facile method development in triple quadrupole mass spectrometry (MS) instruments. To validate the utility of the methods, the differential tissue expression of 107 key ADME proteins was characterized in the tryptic digests of the pooled subcellular fractions of human liver, kidneys, intestines, and lungs. These methods and the data are critical for development of physiologically based pharmacokinetic (PBPK) models to predict xenobiotic disposition.

Abstract
Protein expression of major hepatic uptake and efflux drug transporters in human pediatric (n = 69) and adult (n = 41) livers was quantified by liquid chromatography / tandem mass spectroscopy (LC-MS/MS). Transporter protein expression of OCT1, OATP1B3, P-gp, and MRP3 was age-dependent. Particularly, significant differences were observed in transporter expression (P < 0.05) between the following age groups: neonates vs. adults (OCT1, OATP1B3, P-gp), neonates or infants vs. adolescents and/or adults (OCT1, OATP1B3, and P-gp), infants vs. children (OATP1B3 and P-gp), and adolescents vs. adults (MRP3). OCT1 showed the largest increase, of almost 5-fold, in protein expression with age. Ontogenic expression of OATP1B1 was confounded by genotype and was revealed only in livers harboring SLCO1B1*1A/*1A. In livers >1 year, tissues harboring SLCO1B1*14/*1A showed 2.5-fold higher (P < 0.05) protein expression than SLCO1B1*15/*1A. Integration of these ontogeny data in physiologically based pharmacokinetic (PBPK) models will be a crucial step in predicting hepatic drug disposition in children.

Abstract
OBJECTIVE Gonadotropin-releasing hormone (GnRH) antagonist combined with the human chorionic gonadotropin hormone (hCG) is commonly used in assisted reproduction techniques (ARTs) to induce controlled ovarian hyperstimulation (COH) and to synchronize oocyte maturation. While hCG is known to have immunomodulatory properties, we aimed to assess its effect on immunological changes, with respect to HLA-G binding receptors and embryo implantation success. DESIGN The study involved 103 subjects, including patients undergoing COH protocols (n=66), divided on the basis of the pair's fertility disorder (FD) causes (female FD, n=29; male FD, n=37), and age matched healthy women (n=37). The relative distribution of T cell (CD3+/CD4+, CD3+/CD8+) and NK cell (CD56bright/CD16-, CD56dim/CD16+) populations was evaluated together with HLA-G ligands KIR2DL4 and LILRB1 expression by flow cytometry in the peripheral blood of all subjects, as well as in patient follicular fluids. RESULTS Both groups of patients exhibited a significant decrease of their CD4/CD8 index, a down-modulation of LILRB1-positive CD8 T cells, and increased KIR2DL4-positive NK cell distribution, when compared to the healthy donors. We attribute these changes to the COH protocol, since the only significant change between the patient groups was in the number of cytotoxic CD56dim NK cells (elevated in the female FD group). Patients with male FD causes, having an above-average CD4/CD8 index (≥3.17) and below-average KIR2DL4+/CD56bright NK cell levels(≤13.3%), exhibited higher embryo implantation rates. CONCLUSION The GnRH antagonist/hCG protocol promotes CD3+/CD8+ and KIR2DL4+ NK cell levels, more abundant in subjects with lower implantation rates, and thus decreases the embryotransfer success in otherwise fertile women.

Abstract
Allogeneic HSCT is a curative treatment, when chemotherapy fails, for certain malignant diseases. In Europe, only 15% of the indicated children have an HLA-matched sibling available; in 65-70% of others, HLA allele-matched (9-10/10) UDs can be identified. For the rest, it is necessary to identify other alternative donors (HLA-mismatched family or unrelated cord blood). We present our data of HSCT using HLA partially allele-mismatched (7-8/10) UDs in 24 children with leukemia. Uniform GvHD prophylaxis was used (rATG, CsA and MTX). Acute GvHD grade II was diagnosed in 70.8% of the patients and grade III-IV in 12.5%. Overall incidence of chronic GvHD was 38.7% (extensive in 30%). The probability of EFS was 60.3% (95% CI 35.5-78.1) and OS was 74.9 (95% CI 49.1-88.9). No difference in survival between PBSC and BM recipients was observed. TRM at day + 100 was 4%, and overall was 12.5%. We conclude that used combination of drugs for GvHD prophylaxis is efficient even for patients transplanted with grafts from a HLA-mismatched UDs. It enables stable engraftment, good control of GvHD, full reconstitution of immunity, and is not connected with unacceptable transplant-related mortality.

Abstract
In experiments on dogs with acute left descending coronary artery occlusion, ethmozine (3 mg/kg) was tested for effects on the threshold of ventricular fibrillation occurring as a result of high-frequency electric stimulation. Two hours after occlusion, the fibrillation threshold became significantly lower than the control values. Ethmozine used in this period enhanced the ventricular fibrillation threshold in some experiments and diminished it in the others. Four hours following the occlusion, the fibrillation threshold did not differ from the control ones. Ethmozine given in this period caused a significant increase in the ventricular fibrillation threshold. It was concluded that 4 hours after the onset of experimental myocardial infarction are the minimal time period following which administration of ethmozine failed to decrease electric stability of the heart.

Abstract
The following trends aim to a more efficient exploitation of packed red blood cells (PRBC): 1. Improvement of the operative distribution of PRBCs for transfusions before expiration. 2. Prolongation of the expiration time by monitoring the biochemical and physical processes during banking. Maintenance of native hemoglobin and restoration or substitution of substances involved in transport of energy and of oxygen are of utmost importance. Enzymic conversion of RBCs of blood group A, B to 0 is not supposed to leave laboratory scale soon. While cryo-conservation of RBCs with glycerine is known, freeze-drying of PRBCs remains a speculation. 3. Use of PRBCs after expiration as a raw material for products applicable in medicine and biochemistry. Stroma-free hemoglobin variants (SFH) are known as effective infusable oxygen carriers in experimental animal models. However, there is little convincing evidence on the metabolism and innocuity of SFH variants in human organism. Therefore, systemic infusion of SFH solutions is not yet acceptable to clinicians even in emergency situations. On the other hand, a broader use of SFH and its variants is anticipated and regarded as prospective in organ perfusion, cardioplegy and transplantation as well as in analytical biochemistry.

Abstract
Experiments were made in dogs weighing 15-25 kg with experimental tourniquet shock (35 dogs) and experimental myocardial infarction (29 dogs). Intravenous injection of sodium thiosulfate (500 mg/kg) exerted a marked therapeutic effect on cardio- and central hemodynamics under acute circulatory disturbances both in tourniquet shock and myocardial infarction. Sodium thiosulfate increased cardiac discharge, minute blood flow volume, the first derivative, the threshold of ventricular fibrillation, improved the heart work, decreased and normalized the general peripheral resistance. This effect is likely to be related to the stimulation of intracellular metabolism and antidote action of sodium thiosulfate against ischemic toxin.

Abstract
The entire sequences of the variable region of four heavy chains from BALB/c inulin-binding myeloma proteins have been determined. Among the four proteins there are six amino acid differences, all of which occur in the framework portion of the variable region. All of the six amino acid substitutions can be explained by single base mutations at the DNA level. The pattern of diversity in these proteins is compared to a previously reported group of heavy chains from phosphorylcholine-binding myeloma proteins. Unlike the phosphorylcholine-binding proteins, which (with the exception of two that are identical) have size and sequence differences in their complementarity regions, the inulin-binding heavy chains all have identical complementarity regions with H3 being extremely short. The pattern of variation observed in the anti-inulin heavy chains appears to be most easily explained by a somatic mutation mechanism. However, because none of the substitutions occur in complementarity-determining regions, they presumably would have no selective advantage and would not alter binding specificity. These proteins have further been shown to have crossreacting antigenic determinants (idiotypes). Five of the six sequence differences observed occur at positions that are internal in the molecule and thus presumably would not account for the idiotypic differences. These results suggest that most of the observed idiotypic crossreactivities will be due to differences in the light chains of the anti-inulin proteins.

Abstract
Idiotypes of inulin-binding myeloma proteins (InuBMP) were determined primarly by variable region light chains (VL) or by variable region heavy chains (VH) but needed both chains to be expressed. Recombinant molecules were used to show that individual idiotypes (IdI) of U61, E109, T957, and A4 InuBMP and cross-specific idiotypes (IdXB) of U61 were primarily determined by VL while cross-specific idiotype (IdXA) of A4 was determined mainly by VH. The assignment of genes controlling idiotypes to VH based on allotype linkage (e.g., IdXB) is dubious until the role of the L chain in determining that idiotype is assessed. IdXB has been shown to be a VL-VH marker which presumably is controlled by two unlinked genes. However IdXB can be used as a L chain marker in combinations of strains differing in their L chain genes but having the same permissive H chain genes. Conversely IdXB can be used as a H chain marker in strains having the same permissive L chain genes but differing in their H chain genes.

Abstract
The entire variable-region sequence of the heavy chain from ABE-47N, a BALB/c inulin-binding myeloma protein, has been determined. This protein is unusual in that the third complementarity region (H3) is extremely short, consisting of at the most three and probably only one amino acid. A comparison of the heavy-chain hypervariable regions from mouse, human, and rabbit proteins shows that the variability in length of H3 is greater than that seen in the first or second hypervariable regions. This variability in H3 length suggests a specialized function for this region.

Abstract
13 leven-binding myeloma proteins (LBMP) of BALB/c origin were classified into two groups with different binding specificities; one group of 11 proteins bound beta2 leads to 1 fructosans, a second group of two proteins bound fructosans probably of beta2 leads to 6 linkage. Anti-idiotypic sera prepared to 10 of the proteins in the appropriate strains of mice identified numerous idiotypic determinants. Each protein used for immunization had its own unique individual idiotypic specificities (IdI) and in addition most of the proteins carried two-nine cross-specific or shared idiotypes (IdX) that were found only among LBMP, and not found in 106 non-LBMP. Most of the IdX determinants and only four of the IdI determinants of the beta2 leads to 1 fructosan binding group were located in the antigen-binding site. The multiplicity of antigenic differences in this functionally related group of immunoglobulins reveals an unexpected degree of heterogeneity in V-regions that appears to be unrelated to binding.
