The crude extracts and isolated compounds of Piper porphyrophyllum (Piperaceae) were evaluated for antibacterial and anti-inflammatory activities. The ethyl acetate extract and 3′,4′,5,7-tetramethoxyflavone exhibited the highest activity against Staphylococcus aureus giving values of MIC = 62.5 and 250 μg/mL, respectively. 5-Hydroxy-7-methoxyflavanone and 4′,5-dihydroxy-3′,7-dimethoxyflavone were active against Pseudomonas aeruginosa, both with MIC value 125 μg/mL. The hexane extract and 4′,5-dihydroxy-3′,7-dimethoxyflavone gave the highest anti-inflammatory activity in in vitro quantitative lipoxygenase inhibition assay with inhibitory activity of (IE) 99.72% and 91.81%, respectively.

INTRODUCTION: Breastfeeding is the first step to forming children who are not only healthier but smarter, with a better emotional quotient (EQ) and spiritual quotient (SQ). Babies need physical closeness and warmth from their mother as much as optimal nourishment. Poor knowledge and attitudes towards exclusive breastfeeding can result from information that is not intensive and maximal, due to limited breastfeeding counseling staff. Other reasons include cultural factors, especially in coastal areas, such as the belief in prelacteal feeding before the first breastfeeding; the baby has then automatically not exclusively breastfed. METHODS: This study used an intervention with a one-group pretest–posttest design. It aimed to analyze the role of breastfeeding counseling in increasing mothers' knowledge and attitudes regarding exclusive breastfeeding. The participants were pregnant women from the end of the second trimester to the third trimester, selected using stratified systematic random sampling. RESULTS: Counseling had a significant effect on mothers' knowledge (p = 0.004) and attitude (p = 0.000) in changing the behavior of coastal communities towards giving exclusive breastfeeding (p = 0.03). Intensified counseling is recommended for pregnant women in the third trimester to realize exclusive breastfeeding. CONCLUSIONS: A positive and significant effect of breastfeeding counseling was found on the level of knowledge, attitudes, and changes in the behavior of coastal communities in exclusive breastfeeding.

Bent Laue monochromator HEX is designed with a high-energy non-focusing X-ray monochromator for full-field imaging. The following design ideas apply to the imaging monochromator: The HEX center branch, which the monochromator serves, is white-beam compatible. The monochromator is located in the first optical enclosure with the following parameters: source to monochromator distance is 31 m; monochromator to sample distance is 73 m. Diffraction Enhanced Imaging (DEI) or Analyzer Based Imaging (ABI) uses a perfect crystal monochromator and matching analyzer to achieve sensitivity to X-ray refraction and ultra small-angle scattering on the order of 0.01 micro-radians.

Abstract Background It has been suggested that combined effect of natural products may improve the treatment effectiveness in combating proliferation of cancer cells. The present study was undertaken to evaluate the possibility that the combination of xanthorrhizol and curcumin might show synergistic growth inhibitory effect towards MDA-MB-231 human breast cancer cells via apoptosis induction. The effective dose that produced 50% growth inhibition (GI50) was calculated from the log dose-response curve of fixed-combinations of xanthorrhizol and curcumin generated from the sulforhodamine B (SRB) assay. The experimental GI50 value was used to determine the synergistic activity of the combination treatment by isobolographic analysis and combination-index method. Further investigation of mode of cell death induced by the combination treatment was conducted in the present study. Results Isobole analysis revealed that substances interaction was synergistic when xanthorrhizol and curcumin were added concurrently to the cultures but merely additive when they were added sequentially. The synergistic combination treatment was then applied to the cultures to investigate the mode of cell death induced by the treatment. Immunofluorescence staining using antibody MitoCapture™ revealed the possibility of altered mitochondrial transmembrane potential, which is one of the hallmark of apoptosis. Hoechst 33258 nuclear staining assay showed the rate of apoptosis of MDA-MB-231 cells to increase in response to the treatment. Apoptotic cell death was further confirmed by DNA fragmentation assay, where internucleosomal excision of DNA was induced upon treatment with xanthorrhizol-curcumin. Conclusion This is the first time the combined cytotoxic effect of xanthorrhizol and curcumin on MDA-MB-231 cells has been documented and our findings provide experimental support to the hypothesis that combined xanthorrhizol-curcumin showed synergistic growth inhibitory activity on MDA-MB-231 cells via apoptosis induction.
