Abstract
Background Hemorrhage, a sudden and severe leakage of blood due to the disruption of blood vessels, is one of the most common causes of death from injuries worldwide. Severe bleeding accounts for more than 35% of pre-hospital deaths and about 40% of deaths recorded within 24 hours of injury. One of the methods for achieving homeostasis is the use of hemostatic powders. This study compares the basic safety and performance of the most popular hemostatic powders. Methods Basic safety of commercially available products were evaluated using MTT, MEM elution assay, and endotoxin testing. The in vitro performance was evaluated using water absorption capacity, water absorption rate, and adhesion strength assays. Results 4Seal, Starsil, and 4DryField extracts did not cause cytotoxicity in MTT and MEM elution assays. PerClot and SuperClot extracts demonstrated cytotoxic potential in MTT assay, while Arista extract was cytotoxic in both MEM elution and MTT assays. 4Seal has the lowest endotoxin contamination, followed by PerClot, 4DryField, SuperClot, Arista, and Starsil. 4Seal and Starsil showed significantly highest WAR among the tested samples, followed by 4DryField, Arista, PerClot, and SuperClot. Adhesion force is highest for 4Seal, followed by Starsil, PerClot, 4DryField Arista, and SuperClot. Conclusion 4Seal is the most versatile in terms of safety and functional properties compared to 4DryField, Arista, PerClot, Starsil, and SuperClot.

Abstract
BACKGROUND Tissue adhesives are an alternative to conventional surgical sutures to reduce the time and cost of wound closure and to improve patient comfort. The use of tissue adhesives does not require any subsequent intervention and significantly lowers the volume and rate of blood loss, and reduces the need for transfusions during and after surgery. However, based on their formulation, tissue adhesives' safety profile and functional properties may differ. Therefore, this study aimed to evaluate the basic safety and performance of NE'X Glue® Surgical Sealant, BioGlue® Surgical Sealant, and PREVELEAKTM Surgical Sealant in vitro. METHODS The basic safety of commercially available tissue adhesives was evaluated using MEM elution assay according to ISO 10993-5 and endotoxin level according to 85. USP. The in vitro performance was evaluated using lap-shear by tension loading test, burst strength test, degradation, and swelling assays. RESULTS NE'X Glue®, BioGlue®, and PREVELEAKTM did not cause cytotoxicity in MEM elution assay. All surgical adhesives are below the general limit of endotoxin contamination of 20 EU/device. NE'X Glue® and BioGlue® showed the highest and comparable strength properties in lap shear and burst strength tests compared to PREVELEAKTM. NE'X Glue® and PREVELEAKTM are characterized by lower degradation potential than BioGlue®. PREVELEAKTM is characterized by the highest swelling when compared to NE'X Glue® and BioGlue®. CONCLUSIONS NE'X Glue® is most versatile in terms of functional properties while maintaining the same safety profile as BioGlue® and PREVELEAKTM.

Abstract
Many medical procedures could benefit from the use of tissue sealants which allow for reduced surgery time, limited blood loss, easier tissue handling, and fewer postoperative complications. The safety and biocompatibility of surgical sealants are of paramount importance therefore, the aim of this study is to investigate the biocompatibility of NE’X Glue Surgical Adhesive. Chemical characterization (VOC and elements), cytotoxicity (MEM elution), genotoxicity (AMES and MLA), endotoxin contamination, sensitization potential, intracutaneous reactivity, acute and subchronic systemic toxicity with implantation as well as pyrogenicity were evaluated to investigate the biocompatibility of the NE’X Glue Surgical Adhesive. Studies were conducted according to ISO 10993 standards. The biocompatibility requirements with accordance to ISO 10993-1 for NE'X Glue were met. In vitro studies showed that NE'X Glue surgical adhesive is non-cytotoxic and non-mutagenic. Also, in vivo studies demonstrated that NE'X Glue shows no signs of toxicity, has no pyrogenic potential, and is non-sensitizing and non-irritating. The chemical characterization showed that no compounds were identified above Analytical Evaluation Threshold (AET), and no elements with concentrations higher than element-specific PDE (µg/day) were detected. NE'X Glue Surgical Adhesive is a versatile and promising new surgical sealant with a wide range of potential applications and very good biocompatibility.

Abstract
Cancers account for 85% of renal tumors. In Poland renal cancer is diagnosed in almost four thousands patients every year and two thousands of them dies. The most common subtype of renal cancer is clear cell renal cell carcinoma (ccRCC), which accounts for 80-90% of all renal cancer cases. ccRCC is resistant to chemo- and radiotherapy. More and more data suggest that tumor growth is a result of proliferation and differentiation of a small population of cells called cancer stem cells (CSC). CSCs are responsible for tumor progression and for the resistance to chemo- and radiotherapy. This publication covers the role the CSCs and their origin in renal cell carcinoma, with particular emphasis on clear cell subtype.

Abstract
The use of fetal bovine serum hinders obtaining reproducible experimental results and should also be removed in hormone and growth factor studies. In particular hormones found in FBS act globally on cancer cell physiology and influence transcriptome and metabolome. The aim of our study was to develop a renal carcinoma serum free culture model optimized for (embryonal) renal cells in order to select the best study model for downstream auto-, para- or endocrine research. Secondary aim was to verify renal carcinoma stem cell culture for this application. In the study, we have cultured renal cell carcinoma primary tumour cell line (786-0) as well as human kidney cancer stem cells in standard 2D monolayer cultures in Roswell Park Memorial Institute Medium or Dulbecco’s Modified Eagle’s Medium and Complete Human Kidney Cancer Stem Cell Medium, respectively. Serum-free, animal-component free Human Embryonic Kidney 293 media were tested. Our results revealed that xeno-free embryonal renal cells optimized culture media provide a useful tool in RCC cancer biology research and at the same time enable effective growth of RCC. We propose bio-mimic RCC cell culture model with specific serum-free and xeno-free medium that promote RCC cell viability.

Abstract
Renal cell carcinoma (RCC) is the most lethal of the common urologic malignancies, comprising 3% of all human neoplasms, and the incidence of kidney cancer is rising annually. We need new approaches to target tumor cells that are resistant to current therapies and that give rise to recurrence and treatment failure. In this study, we focused on low oxygen tension and three-dimensional (3D) cell culture incorporation to develop a new RCC growth model. We used the hanging drop and colony formation methods, which are common in 3D culture, as well as a unique methylcellulose (MC) method. For the experiments, we used human primary RCC cell lines, metastatic RCC cell lines, human kidney cancer stem cells, and human healthy epithelial cells. In the hanging drop assay, we verified the potential of various cell lines to create solid aggregates in hypoxic and normoxic conditions. With the semi-soft agar method, we also determined the ability of various cell lines to create colonies under different oxygen conditions. Different cell behavior observed in the MC method versus the hanging drop and colony formation assays suggests that these three assays may be useful to test various cell properties. However, MC seems to be a particularly valuable alternative for 3D cell culture, as its higher efficiency of aggregate formation and serum independency are of interest in different areas of cancer biology.

Abstract
The cancer stem cell (CSC) model has recently been approached also in renal cell carcinoma (RCC). A few populations of putative renal tumor-initiating cells (TICs) were identified, but they are indifferently understood; however, the first and most thoroughly investigated are CD105-positive CSCs. The article presents a detailed comparison of all renal CSC-like populations identified by now as well as their presumable origin. Hypoxic activation of hypoxia-inducible factors (HIFs) contributes to tumor aggressiveness by multiple molecular pathways, including the governance of immature stem cell-like phenotype and related epithelial-to-mesenchymal transition (EMT)/de-differentiation, and, as a result, poor prognosis. Due to intrinsic von Hippel-Lindau protein (pVHL) loss of function, clear-cell RCC (ccRCC) develops unique pathological intra-cellular pseudo-hypoxic phenotype with a constant HIF activation, regardless of oxygen level. Despite satisfactory evidence concerning pseudo-hypoxia importance in RCC biology, its influence on putative renal CSC-like largely remains unknown. Thus, the article discusses a current knowledge of HIF-1α/2α signaling pathways in the promotion of undifferentiated tumor phenotype in general, including some experimental findings specific for pseudo-hypoxic ccRCC, mostly dependent from HIF-2α oncogenic functions. Existing gaps in understanding both putative renal CSCs and their potential connection with hypoxia need to be filled in order to propose breakthrough strategies for RCC treatment.

Abstract
Triiodothyronine plays an important role in the regulation of kidney cell growth, differentiation and metabolism. Patients with renal cell cancer who develop hypothyreosis during tyrosine kinase inhibitor (TKI) treatment have statistically longer survival. In this study, we developed cell based model of triiodothyronine (T3) analysis in RCC and we show the different effects of T3 on renal cell cancer (RCC) cell growth response and expression of the thyroid hormone receptor in human renal cell cancer cell lines from primary and metastatic tumors along with human kidney cancer stem cells. Wild-type thyroid hormone receptor is ubiquitously expressed in human renal cancer cell lines, but normalized against healthy renal proximal tube cell expression its level is upregulated in Caki-2, RCC6, SKRC-42, SKRC-45 cell lines. On the contrary the mRNA level in the 769-P, ACHN, HKCSC, and HEK293 cells is significantly decreased. The TRβ protein was abundant in the cytoplasm of the 786-O, Caki-2, RCC6, and SKRC-45 cells and in the nucleus of SKRC-42, ACHN, 769-P and cancer stem cells. T3 has promoting effect on the cell proliferation of HKCSC, Caki-2, ASE, ACHN, SK-RC-42, SMKT-R2, Caki-1, 786-0, and SK-RC-45 cells. Tyrosine kinase inhibitor, sunitinib, directly inhibits proliferation of RCC cells, while thyroid hormone receptor antagonist 1-850 (CAS 251310‑57-3) has less significant inhibitory impact. T3 stimulation does not abrogate inhibitory effect of sunitinib. Renal cancer tumor cells hypostimulated with T3 may be more responsive to tyrosine kinase inhibition. Moreover, some tumors may be considered as T3-independent and present aggressive phenotype with thyroid hormone receptor activated independently from the ligand. On the contrary proliferation induced by deregulated VHL and or c-Met pathways may transgress normal T3 mediated regulation of the cell cycle.

Abstract
488 Background: Tumor microenvironment is a complex network of multiple cell types, paracrine and endocrine signaling molecules, ECM and physical factors, which orchestrate the fate of tumor progression. In the field of ccRCC little attention has been paid to non-immunologic factors in tumor niche. Objectives of this study include the analysis of hypoxia, triiodothyronine (T3), insulin, insulin-like growth factor-1 and -2 impact on ccRCC cells. The effect of above mentioned tumor niche factors on TKI activity on ccRCC cells was to be quantified. The study was initiated as ccRCC cells are known to harbor disrupted hypoxia response and TRbeta (TRβ) - T3 receptor - functions as a tumor suppressor with tissue hypothyroidism involved in maintaining a proliferative advantage, whereas hypothyroidisms was defined as biomarker of sunitinib treatment efficacy. Moreover obesity and diabetes (DM2) are considered risk factors for ccRCC and high IGF-I expression is associated with poor long-term patient survival. This research aims to find molecular background for clinically relevant observations. Methods: ccRCC cells from primary and metastatic tumors (ATCC, MSK collections) along with cancer progenitor cells (CD133+) were cultured in normoxic or hypoxic conditions; in defined media supplemented with T3, IN, IGF, TRβ inhibitor and TKIs (sunitinib, axitinib). Cell proliferation was evaluated using AlamarBlue and MTT. Colony formation potential was evaluated. TRβ gene expression was measured with RealTime-RT PCR and sequenced under standard protocol. Normal kidney proximal tube cells were used as negative control. Results: ccRCC TKI responsiveness is limited by hypoxia, at the same time tumor cell proliferation may be promoted by T3, IN and IGF. Colony formation potential of ccRCC cells under TKI treatment in hypoxic conditions is downregulated. Conclusions: Multiple micro-environmental factors modify the proliferation and/or differentiation of ccRCC cell populations. Understanding the complex molecular feedback loops between cancer cells and the surrounding microenvironment should aid the identification of novel targets for improving TKIs clinical management.

Abstract
Prokaryotic Cu,Zn superoxide dismutases are characterized by a distinct quaternary structure, as compared to that of the homologous eukaryotic enzymes. Here we report a newly determined crystal structure of the dimeric Cu,Zn superoxide dismutase from Photobacterium leiognathi (crystallized in space group R32, refined at 2.5 A resolution, R-factor 0.19) and analyse it in comparison with that of the monomeric enzyme from Escherichia coli. The dimeric assembly, observed also in a previously studied monoclinic crystal form of P. leiognathi Cu,Zn superoxide dismutase, is based on a ring-shaped subunit contact region, defining a solvated interface cavity. Three clusters of neighbouring residues play a direct role in the stabilization of the quaternary assembly. The present analysis, extended to the amino acid sequences of the other 11 known prokaryotic Cu,Zn superoxide dismutases, shows that at least in five other prokaryotic enzymes the interface residue clusters are under strong evolutionary constraint, suggesting the attainment of a quaternary structure coincident with that of P. leiognathi Cu,Zn superoxide dismutase. Calculation of electrostatic fields for both the enzymes from E. coli and P. leiognathi shows that the monomeric/dimeric association behaviour displayed by prokaryotic Cu, Zn superoxide dismutases is related to the distribution of surface charged residues. Moreover, Brownian dynamics simulations reproduce closely the observed enzyme:substrate association rates, highlighting the role of the active site neighbouring residues in determining the dismutase catalytic properties.
