Chemical Composition, Phytochemical Constituent, and Toxicity of Methanol Extract of Brown Algae (Padina sp.) from Puntondo Coast, Takalar (Indonesia)

Background: Padina sp. is an algae that has potential as a functional food. This study aimed to explore the chemical and photochemical constituent in the methanolic exract of Padina sp. Methods: Brown algae of Padina sp. from Puntondo coast, Takalar, Indonesia was prepared. The algae characterization was carried out based on the standard procedure of Association of Official Agricultural Chemists (AOAC). Toxicity of Padina sp. was. determined with Brine Shrimp Lethality Test (BSLT). Results: Chemical contents were 13.46% water, 38.02% ash, 12.33% protein, 1.60% fat, 20.02% fiber, and 48.06% carbohydrate. The FTIR spectrum displayed the presence of hydroxyl, carboxylic acids, aldehydes, aliphatic hydrocarbons, fatty acids, and unsaturated hydrocarbons. Padina sp. extract consisted of phytol compound which had 70-96% similarity with steroids, fatty acids, carboxylic acids, terpenoid, and proteins. The result of toxicity was 6344.54 ppm indicating not toxic. Conclusion: Padina sp. can be used as a raw material source for functional food and pharmaceutical industry.

PENGARUH PEMBERIAN ASI TERHADAP PERKEMBANGAN ANAK USIA 6 – 12 BULAN DI RW 04 DESA SAMBIBULU KECAMATAN TAMAN SIDOARJO

This research is to observe the purpose of this study was to analyze the influence of breastfeeding toward the development of children aged 6 - 12 months living in RW 04 Sambibulu Village, Taman Sub-district, Sidoarjo. The design of  research was analytic  retrospective  study. The population involved 29 couples with their children aged 6  -  12 months living in the above mentioned region. The simple random sampling technique was used to take 27 couples as the samples of research. The independent variable of this research was breastfeeding, whereas the dependent one was  the child’s development. Questionnaires of breast and checklist of KPSP (Pre Screening Questionnaire for Child Development) were used to collect the data which analyzed by using Mann-Whitney’s statistic test with the significance level α = 0.05, it means that there was a relationship between breastfeeding and  the development of children p (0.000) < α (0.05)

In vivo comparison of local versus systemic delivery of immunostimulating siRNA in HPV-driven tumours

Small interfering RNAs (siRNAs) to inhibit oncogene expression and also to activate innate immune responses via Toll-like receptor (TLR) recognition have been shown to be beneficial as anti-cancer therapy in certain cancer models. In this study, we investigated the effects of local versus systemic delivery of such immune-stimulating Dicer-substrate siRNAs (IS-DsiRNAs) on a human papillomavirus (HPV)-driven tumour model. Localized siRNA delivery using intratumour injection of siRNA was able to increase siRNA delivery to the tumour compared with intravenous (IV) delivery and potently activated innate immune responses. However, IV injection remained the more effective delivery route for reducing tumour growth. Although IS-DsiRNAs activated innate immune cells and required interferon-α (IFNα) for full effect on tumour growth, we found that potent silencing siRNA acting independently of IFNα were overall more effective at inhibiting TC-1 tumour growth. Other published work utilising IS-siRNAs have been carried out on tumour models with low levels of major histocompatibility complex (MHC)-class 1, a target of natural killer cells that are potently activated by IS-siRNA. As TC-1 cells used in our study express high levels of MHC-class I, the addition of the immunostimulatory motifs may not be as beneficial in this particular tumour model. Our data suggest that selection of siRNA profile and delivery method based on tumour environment is crucial to developing siRNA-based therapies.
