Antimicrobial and Antioxidant Efficacy of the Lipophilic Extract of .

The aim of this study was to investigate the compounds in the hexane extract of (Savi.) Ten. and to determine the antibacterial, antifungal, and antioxidant activities of different extracts.

Curcumin-meropenem synergy in carbapenem resistant curcumin-meropenem synergy.

Background And Objectives: The frequency of multiple resistant bacterial infections, including carbapenems, is increasing worldwide. As the decrease in treatment options causes difficulties in treatment, interest in new antimicrobials is increasing. One of the promising natural ingredients is curcumin.

Relationship between serum soluble endothelial protein C receptor level and COVID-19 findings.

Coronavirus-related disease-2019 (COVID-19)-associated coagulopathy presents predominantly with thrombosis and leads to complications in close association with inflammatory process. Soluble endothelial protein C receptor (sEPCR), which is the soluble form of EPCR, reduces the anticoagulant and anti-inflammatory activity of activated protein C. The purpose of this study is to investigate the relationship between sEPCR and the laboratory parameters and thorax computed tomography (CT) findings in the course of COVID-19.

Antibacterial effects of curcumin: An in vitro minimum inhibitory concentration study.

Aim: To evaluate the antibacterial effect of curcumin with the minimum inhibitory concentration (MIC) method in standard bacterial strains.

Methods: The in vitro antibacterial activity of curcumin was evaluated against methicillin-sensitive Staphylococcus aureus (MSSA) (ATCC 29213), methicillin-resistant Staphylococcus aureus (MRSA) (ATCC 43300), Enterococcus faecalis (ATCC 29212), Bacillus subtilis (ATCC 6633), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922) and Klebsiella pneumoniae (ATCC 700603) using the macrodilution broth susceptibility test method. After incubation in tubes, the antibacterial activity of curcumin was detected by a lack of turbidity, which indicated the inhibition of bacterial growth.

Tumor regulation of myeloid-derived suppressor cell proliferation and trafficking.

A stress response can induce myeloid progenitor cell (MPC) proliferation, mobilization, and extramedullary hematopoiesis (EMH) within lymphoid and parenchymal organs. Our studies using in vivo BrdU labeling, Ki-67 IHC staining, and carboxyfluorescein succinimidyl ester (CFSE) adoptive cell transfer revealed that spleens, rather than bone marrow (BM) and peripheral blood (PB), from 4T1 mammary tumor-bearing (TB) mice were the primary site of MPC proliferation. The resultant increase in MPCs was associated with tumor hematopoietic growth factor (GF) transcription, decreased apoptosis, as well as, prolonged survival of splenic MPCs.

Mammary tumor heterogeneity in the expansion of myeloid-derived suppressor cells.

The tumor microenvironment is heterogeneous for the expansion and infiltration by myeloid derived suppressor cells (MDSCs) which has been hypothesized to be dependent on tumor burden. We report a relationships between tumor size, MDSCs and T-cells; using four murine mammary tumors to assess tumor growth, infiltration and gene expression. Our analysis of cellular infiltration into tumors and gene expression used collagenase dissociated tumors and density gradient isolation of non-parenchymal cells (NPCs).

Closing the manufacturing process of dendritic cell vaccines transduced with adenovirus vectors.

Anticancer immunotherapy using dendritic cell (DC) based vaccines provides an adjuvant therapeutic strategy that is not cross reactive with conventional therapeutics. However, manufacturing of DC vaccines requires stringent adherence to Good Manufacturing Practice (GMP) methods and rigorous standardization. Optimally this includes a closed system for monocyte isolation, in combination with closed culture and washing systems and an effective vector transduction strategy.

Synthesis of new 2,5-disubstituted-1,3,4-thiadiazoles and preliminary evaluation of anticonvulsant and antimicrobial activities.

Two new series of 2,5-disubstituted-1,3,4-thiadiazoles were synthesized for their possible anticonvulsant, antibacterial and antifungal activities. The degree of protection afforded by these compounds at a dose of 100mg/kg i.p.
