Background: Uterine sarcomas and carcinosarcoma are associated with unfavorable prognosis. The regimens that are used in chemotherapy are associated with high incidence of side effects and usually do not significantly increase patients’ survival rates. In this study we investigated the activity and interactions between gemcitabine and fucoidan, the natural compound known for its anti-tumor properties, in human sarcomas and carcinosarcoma cell models. Methods: SK-UT-1, SK-UT1-B (carcinosarcoma), MES-SA (leiomyosarcoma), and ESS-1 (endometrial stromal sarcoma) cell lines were used for the experiments. Cells were incubated in the presence of gemcitabine, fucoidan, and mixtures, after the incubation the MTT tests were performed. In order to assess the interactions between tested compounds isobolographic analysis was performed. Additional assessments of apoptosis and cell cycle were done. Results: Additive effect of combined treatment with gemcitabine and fucoidan was observed in ESS-1 and SK-UT-1 cell line. Although the supra-additive (synergistic) effect noticed in SK-UT-1B cell line. It was not possible to determine the interactions of fucoidan and gemcitabine in MES-SA cell line due to insufficient response to treatment. Addition of fucoidan to gemcitabine enhances its proapoptotic activity, what was observed especially in ESS-1 and SK-UT-1B cell lines. The arrest of cell cycle induced by mixture of gemcitabine and fucoidan, superior comparing gemcitabine alone was observed in SK-UT-1B. Conclusions: Obtained data showed that a combination of fucoidan and gemcitabine in uterine endometrial stromal sarcoma and carcinosarcoma cell lines has additive or even synergistic effect in decreasing cell viability. Furthermore, this drug combination induces apoptosis and arrest of cell cycle. The resistance of uterine leiomyosarcoma cell line, justifies searching for other drugs combinations to improve therapy efficacy.

This paper investigates the performance, combustion and emission characteristics of a direct injection (DI) diesel engine, fueled with alumina ($$\hbox {Al}_{2} \hbox {O} _{3})$$ Al2O3) nanoparticles-dispersed aloe vera diesel blends. The test fuels B10 (90% diesel and 10% aloe vera biodiesel), $$\hbox {B10}+ \hbox {Al}_{2} \hbox {O}_{3}$$ B10+Al2O3 (90% diesel, 10% aloe vera biodiesel and 30 ppm of $$\hbox {Al}_{2} \hbox {O}_{3}$$ Al2O3 nanoparticles), B20 (80% diesel and 20% aloe vera biodiesel) and $$\hbox {B20}+ \hbox {Al}_{2} \hbox {O}_{3}$$ B20+Al2O3 (80% diesel, 20% aloe vera biodiesel and 30 ppm of $$\hbox {Al}_{2} \hbox {O}_{3}$$ Al2O3 nanoparticles) are prepared separately for each aloe vera diesel blends at a dosage of 30 ppm with an aid of an ultrasonicator. The combustion characteristics such as heat release rate and cylinder pressure are investigated using the data acquisition system, while the engine performance features are examined by brake-specific fuel consumption and brake thermal efficiency. The levels of engine pollutants are analyzed by unburned hydrocarbon (UBHC), carbon monoxide (CO), nitric oxide (NO) and smoke opacity. These investigations disclosed the use of biodiesel blends with $$\hbox {Al}_{2} \hbox {O}_{3}$$ Al2O3 nanoparticles in DI diesel engine with significant amelioration of combustion characteristic and substantial decrement of CO, NO, smoke, UBHC emissions and brake thermal efficiency by 44%, 47%, 37%, 29% and 3%, when compared with the diesel fuel.

Reactive oxygen species (ROS) produced during intracellular metabolism or triggered by extrinsic factors can promote neoplastic transformation and malignant microenvironment that mediate tumor development. Oligo-Fucoidan is a sulfated polysaccharide isolated from the brown seaweed. Using human THP-1 monocytes and murine Raw264.7 macrophages as well as human HCT116 colorectal cancer cells, primary C6P2-L1 colorectal cancer cells and human MDA-MB231 breast cancer cells, we investigated the effect of Oligo-Fucoidan on inhibiting M2 macrophage differentiation and its therapeutic potential as a supplement in chemotherapy and tumor prevention. We now demonstrate that Oligo-Fucoidan is an antioxidant that suppresses intracellular ROS and mitochondrial superoxide levels in monocytes/macrophages and in aggressive cancer cells. Comparable to ROS inhibitors (DPI and NAC), Oligo-Fucoidan directly induced monocyte polarization toward M1-like macrophages and repolarized M2 macrophages into M1 phenotypes. DPI and Oligo-Fucoidan also cooperatively prevented M2 macrophage invasiveness. Indirectly, M1 polarity was advanced particularly when DPI suppressed ROS generation and supplemented with Oligo-Fucoidan in the cancer cells. Moreover, cisplatin chemoagent polarized monocytes and M0 macrophages toward M2-like phenotypes and Oligo-Fucoidan supplementation reduced these side effects. Furthermore, Oligo-Fucoidan promoted cytotoxicity of cisplatin and antagonized cisplatin effect on cancer cells to prevent M2 macrophage differentiation. More importantly, Oligo-Fucoidan inhibited tumor progression and M2 macrophage infiltration in tumor microenvironment, thus increasing of anti-tumor immunity.

Abstract Background Aloe vera is a plant that has been used as an alternative drug. This plant contains various compounds, like anthraquinone, saponin, flavonoid, alkaloid, and tannin that has an antibacterial effect against Staphylococcus aureus and Escherichia coli. Both of it were responsible for the infection incident. This study aims to determine the efficacy of Aloe vera sap as an antibacterial against Staphylococcus aureus and Escherichia coli. Methods An experimental study, in vitro using post-test only control group design, has been done at laboratory of Medical Faculty of Sriwijaya University, by examining the antibacterial activity of Aloe vera sap in five different concentration (5%, 10%, 20%, 40%, dan 80%) using well diffusion and solid dillusion method to determine the minimum bactericidal concentration (MBC). And then continued with the phytocemical screening to determine the compound inside the Aloe vera sap. Results Aloe vera sap were able to kill Staphylococcus aureus at 5% and Eshcerichia coli at 80%. Compatibility test showed that Aloe vera sap with concentration of 10%, 20%, 40%, and 80% are compatible with amoxicillin, therefore 80% is compatible with cefotaxime. This ability due to the compound that it contains, which is alkaloid, flavonoid, tannin, quinone, and saponin. Conclusion Aloe vera sap is effective as an antibacterial against Staphylococcus aureus and Escherichia coli.   Keyword: Aloe vera sap, antibacterial, efficacy, Staphylococcus aureus, Escherichia coli.  

Hydroactive wound dressings ensure a physiologically moist wound milieu which enhances healing and patient comfort. Polymers like polyurethane, salts of alginic acid, collagen, cellulose and other gelable polysaccharides are commonly used for preparation of hydrogels but have their own limitations. In the present study acacia gum, a natural polysaccharide having known antioxidant and wound healing properties has been blended with polyvinyl alcohol and prepared hydrogel matrix further explored for its wound healing potential. Structural characterization of blended films by FTIR and XRD method showed that polysaccharide gum associated with PVA molecules via acetal bridges and they were amorphous in nature. The gel exhibited free swell capacity of 64 g 0.100 cm−2, which is comparable to the commercially available films recommended for heavily exuding wounds. The GA/PVA blends showed 34% moisture retention (Rh) ability after 24 h and their fluid absorbing (26%) and fluid donation (16%) ability make them suitable for moist and fibrinous wounds. They also exhibited blood compatibility, oxygen permeability, bacterial impermeability, antioxidant activity, iron chelation ability and biodegradability. In vivo healing potential has been evaluated on Swiss albino mice where hydrogel coated wounds showed faster and scar-less wound regeneration. In vitro Povidone-Iodine loading and release studies showed that iodine release followed Fickian diffusion process. Prepared hydrogels are breathable and hydrophilic in nature and are able to maintain appropriate moisture level at wound surface, suitable for acceleration of wound healing process. Based upon the studied properties the designed hydrogels are recommended for dry, necrotic and low exuding wounds.

Background. Use of herbal compounds as an intracanal medicament in the field of endodontics has become noteworthy, one of which is the Aloe vera compound whose antibacterial effect has already been proven in the planktonic form of Enterococcus faecalis. The purpose of this study is to evaluate the antibacterial effect of Aloe vera on E. faecalis biofilms at the 4th and 6th week of development. Materials and Methods. 130 single root canal teeth without anomalies and caries were used. They were divided into two groups of 65 teeth for four and six weeks of biofilm production. Five samples of each group were examined for confirmation of biofilm formation under an electron microscope. Study groups were investigated with an antimicrobial agent as an intracanal medicament including 20 samples treated with Aloe vera, calcium hydroxide, and phosphate-buffered saline, and biofilm and survival of pathogens were investigated. Dentin chip suspensions were used for colony-forming unit (CFU) counting to estimate remaining E. faecalis counts. Results. The CFU mean in the 4th week subgroup in Aloe vera, phosphate-buffered saline, and calcium hydroxide was 0, 69166.66 ± 31688.58, and 25000 ± 30822.07, and in the 6th week, it was 136.36 ± 323.33, 95000 ± 12247.44, and 27501.66 ± 36570.34, respectively, which showed a significant difference between the used materials (). Conclusion. Aloe vera, in contrast to calcium hydroxide, eliminated 4th and 6th week biofilms and showed remarkable antibacterial properties against E. faecalis biofilm. These results support potency of Aloe vera to use as a natural antimicrobial material in the intracanal medicament.
