Abstract
Lymphoid organs are the main structural components of the immune system. In the current research, the mixture of poly lactic-co-glycolic acid (PLGA), polycaprolactone (PCL), and M13 phage or its RGD-modified form was used in the construction of a fibrillar scaffold using the electrospinning method. The constructs were transplanted intra-abdominally and examined for the formation of lymphoid-like tissues at different time intervals. The confocal and scanning electron microscopy demonstrate that M13 phage-containing scaffolds provide a suitable environment for lymph node-isolated fibroblasts. Morphological analysis demonstrate the formation of lymph node-like tissues in the M13 phage-containing scaffolds after transplantation. Histological analysis confirm both blood and lymph angiogenesis in the implanted construct and migration of inflammatory cells to the M13 phage-containing scaffolds. In addition, flow cytometry and immunohistochemistry analysis showed the homing and compartmentalization of dendritic cells (DCs), B and T lymphocytes within the PLGA/PCL/M13 phage-RGD based scaffolds and similar to what is seen in the mouse lymphoid tissues. It seems that the application of M13 phage could improve the generation of functional lymphoid tissues in the electrospun scaffolds and could be used for lymphoid tissue regeneration.

Abstract
Introduction: Coronavirus disease 2019 (COVID-19) is characterized by impaired oxygen (O2) homeostasis, including O2 sensing, uptake, transport/delivery, and consumption. Red blood cells (RBCs) are central to maintaining O2 homeostasis and undergo direct exposure to coronavirus in vivo. We thus hypothesized that COVID-19 alters RBC properties relevant to O2 homeostasis, including the hematological profile, Hb O2 transport characteristics, rheology, and the hypoxic vasodilatory (HVD) reflex. Methods: RBCs from 18 hospitalized COVID-19 subjects and 20 healthy controls were analyzed as follows: (i) clinical hematological parameters (complete blood count; hematology analyzer); (ii) O2 dissociation curves (p50, Hill number, and Bohr plot; Hemox-Analyzer); (iii) rheological properties (osmotic fragility, deformability, and aggregation; laser-assisted optical rotational cell analyzer (LORRCA) ektacytometry); and (iv) vasoactivity (the RBC HVD; vascular ring bioassay). Results: Compared to age- and gender-matched healthy controls, COVID-19 subjects demonstrated 1) significant hematological differences (increased WBC count-with a higher percentage of neutrophils); RBC distribution width (RDW); and reduced hematocrit (HCT), Hb concentration, mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration (MCHC); 2) impaired O2-carrying capacity and O2 capacitance (resulting from anemia) without difference in p50 or Hb-O2 cooperativity; 3) compromised regulation of RBC volume (altered osmotic fragility); 4) reduced RBC deformability; 5) accelerated RBC aggregation kinetics; and (6) no change in the RBC HVD reflex. Discussion: When considered collectively, homeostatic compensation for these RBC impairments requires that the cardiac output in the COVID cohort would need to increase by ∼135% to maintain O2 delivery similar to that in the control cohort. Additionally, the COVID-19 disease RBC properties were found to be exaggerated in blood-type O hospitalized COVID-19 subjects compared to blood-type A. These data indicate that altered RBC features in hospitalized COVID-19 subjects burden the cardiovascular system to maintain O2 delivery homeostasis, which appears exaggerated by blood type (more pronounced with blood-type O) and likely plays a role in disease pathogenesis.

Abstract
Bacteriophages are one of the viral components of the human microbiome. M13 phages have recently been considered for immunotherapy because they can be detected by immune cells and stimulated immune responses. Macrophages are essential innate immune cells that respond to stimuli and direct subsequent immune responses. Therefore, it is crucial to evaluate the immunomodulatory effect of phage on macrophage function. For this purpose, peritoneal macrophages from BALB/c and C57BL/6 mice were cultured on the M13 phage, M13 phage-RGD, gelatin-coated, and un-coated wells. Then macrophages were examined for morphological characteristics, L. arginine metabolism, redox potential, inflammatory cytokine production, and phagocytic activity after two and seven days of culture. We observed that M13 phage-coated surfaces induced anti-inflammatory cytokines production and reduced inflammatory cytokines level of BALB/c and C57BL/6 macrophages at the steady-state and post LPS stimulation. In addition, L. arginine metabolism and phagocytic activity of macrophages were directed to the M2 phenotype by induction of arginase-1 and efferocytosis in the M13 phage-containing groups, respectively. The present study confirms the M13 phage's ability to polarize macrophages toward the M2 phenotype. However, using M13 phage in treating inflammatory diseases in animal models could determine their immunotherapy capacity in the future.

Abstract
AIMS Platelet production improvement can resolve concerns about the limitations of external platelet supply and platelet transfusion in thrombocytopenia patients. To this end, scientists encourage to induce the generation of megakaryocyte and platelet. Curcumin is a safe ingredient of turmeric that affects various cellular pathways. The effect of this component on platelet production has not been yet reported. MAIN METHODS Our in vitro experiments include the investigation of the effects of nanocurcumin on megakaryocytes production from K562 cells and hematopoietic stem cells via megakaryocyte markers expression, DNA content, ROS, and morphologic analysis, and CFC assay. The regulatory functions of MAPKs pathways were also determined. In the in vivo study tissue distribution of nanocurcumin was determined and two treatment schedules were used to evaluate the capability of nanocurcumin to prevent the occurrence of Busulfan-induced thrombocytopenia in the mouse model. KEY FINDING In vitro evidences demonstrated that nanocurcumin can induce MK production from K562 cells and hematopoietic stem cells. Inhibition of ERK1/2 and JNK pathways arrested this activity. In vivo experiments showed the uptake of nanocurcumin by tissues in mice. Administration of nanocurcumin could preserve bone marrow integrity and increase of the number of circulating platelets in the Busulfan-treated mice models. SIGNIFICANCE Our results have demonstrated that nanocurcumin administration can be useful for the improvement of megakaryocytes and platelet generation in vitro. This component may be exerting these beneficial effects on megakaryopoiesis by modulating ERK1/2 and JNK pathways. As well as nanocurcumin has the potential to prevent thrombocytopenia in chemotherapy threated mice.

Abstract
One of the most important goals of regenerative medicines is to generate alternative tissues with a developed vascular network. Endothelial cells are the most important cell type required in angiogenesis process, contributing to the blood vessels formation. The stimulation of endothelial cells to initiate angiogenesis requires appropriate extrinsic signals. The aim of this study was to evaluate the effects of M13 phage along with RGD peptide motif on in vitro and in vivo vascularization. The obtained results demonstrated the increased cellular proliferation, HUVECs migration, cells altered morphology, and cells attachment to M13 phage-RGD coated surface. In addition, the expression of Vascular Endothelial Growth Factor A (VEGF-A), VEGF Receptors 2 and 3, Matrix Metalloproteinase 9 (MMP9), and epithelial nitric oxide synthase (eNOS) transcripts were significantly upregulated due to the HUVECs culturing on M13 phage-RGD coated surface. Furthermore, VEGF protein secretion, nitric oxide, and reactive oxygen species (ROS) production were significantly increased in cells cultured on M13 phage-RGD coated surface.

Abstract
Leukemic cells can impact the bone marrow niche to create a tumor-favorable microenvironment using their secreted factors. Little knowledge is available about immunosuppressive and tumor-promoting properties of chronic myeloid leukemia derived exosomes in bone marrow stromal components. We report here that K562-derived exosomes can affect the gene expression, cytokine secretion, nitric oxide (NO) production, and redox potential of bone marrow mesenchymal stem cells (BM-MSCs) and macrophages. Human BM-MSCs and mouse macrophages were treated with K562-derived exosomes. Our results demonstrated that the expression of the genes involved in hematopoietic developmental pathways and immune responses, including C-X-C motif chemokine 12 (Cxcl12), Dickkopf-related protein 1 (DKK1), wnt5a, interleukin 6 (IL-6), transforming growth factor-beta, and tumor necrosis factor-alpha (TNF-alpha), changed with respect to time and exosome concentration in BM-MSCs. The TNF-alpha level was higher in exosome-treated BM-MSCs compared with the control. Exosome treatment of BM-MSCs led to an increased production of NO and a decreased production of reactive oxygen species (ROS) in a time- and concentration-dependent manner. We have shown that K562-derived exosomes induce overexpression of IL-10 and TNF-alpha and downregulation of iNOS transcript levels in macrophages. The enzyme-linked immunosorbent assay results showed that TNF-alpha and IL-10 secretions increased in macrophages. Treatment of macrophages with purified exosomes led to reduced NO and ROS levels. These results suggest that K562-derived exosomes may alter the local bone marrow niche toward a leukemia-reinforcing microenvironment. They can modulate the inflammatory molecules (TNF-alpha and NO) and the redox potential of BM-MSCs and macrophages and direct the polarization of macrophages toward tumor-associated macrophages.

Abstract
It is aimed to evaluate the actual anti-cancerous effects of metformin on cancer cells in hypoxic condition. Non-cancerous cells (HEK293) and cancer cells (MCF-7) were cultured in both hypoxia and normoxia conditions and treated with different concentrations of metformin. The proliferation, apoptosis, and necrosis rate were assessed using MTT test and Annexin V assay. The S6K1 phosphorylation was assessed using western blotting. Zymography was used to measure the activity of metalloproteinase-9 (MMP-9). Metformin treatment inhibited proliferation of cancer cells in the optimal concentration of 10 mM under hypoxia condition, while it showed no effects on non-cancerous cell viability. The statistical analysis of MTT assay indicated that the pro-apoptotic function of metformin for cancer cells under hypoxia condition compared to normoxia was significant with different metformin concentrations (p<0.01). However, the effect of metformin treatments for non-cancerous cells under hypoxia condition compared to normoxia was not significant. Western-blot analysis indicated a significant decrease in S6K1 phosphorylation in cancer cells under hypoxia condition (p<0.05). Nevertheless, there was no considerable difference between normoxia and hypoxia conditions in non-cancerous cells. MMP-9 zymography analysis revealed that the highest inhibition of MMP-9 activity was observed in hypoxia condition by 20mM of metformin concentration only in cancer cell. The results indicate that in hypoxia condition metformin exerts its anti-cancerous function by inhibiting proliferation and tumor progression and inducing cell apoptosis more effectively than normoxia condition. In line with cancer cell conditions, most importantly hypoxic condition, metformin can be considered as a potential anti-cancerous drug.

The complexation reactions between Ni(2+), Co(2+) and Zn(2+) metal ions with PAN in methanol (MeOH), acetonitrile (AN) and dimethyl sulfoxide (DMSO) were studied using a spectrophotometric method. The stability constants of the resulting complexes were determined from computer fitting absorbance mole-ratio data. The results revealed that the stability constants of complexes are varying in order of Ni(2+)<Zn(2+)<Co(2+) for all solvents. The values of the thermodynamic parameters (ΔH°, ΔS° and ΔG°) for complexation reactions were obtained from the temperature dependence of the stability constants.
