Antibreast Cancer Activity of Nanopropolis Indonesia on Induced Mammary Gland Tumor by Dmba in Virgin Sprague-dawley Rats

The objective of this study was to determine the effect of nanopropolis to cure cancer induced on rat mammary tumor using 7,12-dimethylbenz(a)anthracene (DMBA). After the first tumors appearance, twenty eight rats were divided into seven groups. Group 1, 2 and 3 served as recipient of nanopropolis dosages 8, 32 and 56 µg/mL treatments; Group 4 served asrecipient of propolis dosage of 233 µg/mL treatment; Group 5 served asrecipient of doxorubicin treatment; Group 6 served as recipient of DMBA treatment and Group 7 as normal group (control). The effect of nanopropolis dosage of 32 µg/mL and propolis dosage of 233 µg/mL were similar in reducing tumor size, healing the wounds caused by the tumor and eliminating cancer cells. It turns out that there is a relationship between particle size absorbent materials. The study suggested that nanopropolis with small concentration was very effective to treatrat mammary gland tumors and breast cancers

The Current State of Climate Change Perceptions and Policies in Vietnam: 2014 Report

This report was constructed to assess the current perceptions and policies regarding climate change in Vietnam. The report comprises a country report, outlining current policies relating to climate change, stakeholder mapping regarding climate change locally and nationally, and results from two stakeholder perception surveys conducted locally and nationally in Vietnam. A total of 50 stakeholders were interviewed, 25 locally and 25 nationally. The stakeholders in the survey represented government offices, universities, research institutions, NGOs, and farmers’ groups. Concerns about climate change impacts included drought, flooding, rainfall variation, and salinity intrusion. These concerns, as well as the methods in which stakeholders would like to receive climate information, varied between local and national stakeholders as well as by the type of institution that the stakeholder represented. This emphasizes a need for location- and user-specific responses to climate change

Immunoregulatory effects of AFP domains on monocyte-derived dendritic cell function

<p>Abstract</p> <p>Background</p> <p>Alpha-fetoprotein (AFP) is a tumor-associated glycoprotein that functions in regulation of both ontogenic and oncogenic growth. Recent study showed that AFP can induce apoptosis or impair monocyte-derived dendritic cell (MDDC) function. However, it is still unclear which AFP domain (D-AFP) plays major role in this function.</p> <p>Results</p> <p>As expected monocytes cultured in the presence of Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) and Interleukin-4 (IL-4) developed into MDDC. Up-regulation of HLA-DR and CD11c as well as loss of CD14 molecules could be observed. Full length AFP (FL-AFP), domain 2 AFP (D2-AFP) and D3-AFP, but not D1-AFP, significantly inhibited the expression of HLA-DR^high/CD11c^highand CD80⁺/CD86^highmolecules. In contrast, CD83 expression was substantially down-regulated in all samples. Expression of CD40 was significantly suppressed by FL-AFP but not by any D-AFPs. Finally, both FL-AFP and D-AFP impaired the MDDC ability to secrete IL-12 (p70).</p> <p>Conclusions</p> <p>D2- and D3- but not D1-AFP extensively suppresses the MDDC function. All the recombinant AFP proteins impaired the ability of MDDC to secrete IL-12.</p
