Abstract

Canna Sp. is one of the plants that can live in conditions of wetland cultivated in freshwater courses, which often serve as recipients for domestic and other sorts of wastewater. In the context of its life ability, this study deals to investigate the capacity of Canna Sp. in uptake toxic heavy metal mercury from a wetland system. Canna Sp. was cultivated in a polybag contained wastewater for a couple months to reach acclimatization. The wastewater contained mercury ions in different concentrations of 1.2; 0.96 and 0.36 mg-Hg/L. Each polybags contained five stems of Canna Sp. Control media (contain no mercury in media) were also prepared for these treatments. During 14 days of the experiment, the atmospheric air and water temperature (30+3 oC is optimum) were maintained and every five days, length of stems, concentration of mercury ion in water phase, and its tissue were analyzed. The concentration of mercury in shoots, leaves, and roots were analyzed by Atomic Absorption Spectrophotometer, Shimadzu AA 6300 after destructed using TCLP method. Results showed that Canna Sp. has resistant a survival on water phase containing mercury and it inhibits the growth of Canna Sp. in the log phase. The highest mercury ion uptake by Canna Sp. occurred in the root (1.16 – 1.34 mg-Hg/kg) compared to the leaves (0.05 – 0.33 mg-Hg/kg) and the shoots (0.29-0.69 mg-Hg/kg). These results reached to the conclusion that Canna Sp. has a potential for mercury phytoremediation application in a wetland system.

Abstract

The discovery of micro RNA (miRNA) in 1993 by Ambros and colleagues has a huge influence in pathogenesis theory, diagnosis and treatment approach of some diseases. Some studies have conducted to seek the association alterations of miRNA expression to incidences and severity of preeclampsia (PE). We have reviewed some studies that conducted to seek the association of miRNA and PE and we discussed the role of various miRNAs in PE pathogenesis. In summary, we have shown that many researchers have given evident that the different placental and plasma miRNA expression is associated with PE. Some studies also identified the novel candidate of miRNAs (and their pathways) that may be of etiologic relevance in the pathogenesis of PE. Base on review, specific miRNA have a role to down regulate of anti apoptosis genes, regulate angiogenics growth factors such as angiogenin, vascular endothelial growth factor (VEGF) B (VEGF-β), cysteine-rich 61 (CYR61), Placental growth factor (PlGF) and VEGF-A that have a role in angiogenesis. miRNA also have a role in  survival, migration, and capillary tube formation of HUVEC by targeted of c-kit. Some miRNAs target genes that participate in immunologic dysfunction, cell adhesion, cell cycle, and signaling. miRNA also have a roles in endothelial cell response to hypoxia, cell differentiation, and survival. A miRNA influence calcium signaling through negative regulations of the calmodulin-coding mRNAs, Mef2a and Gata4, mainly in smooth muscle cells that contribute to PE pathogenesis. These investigations provide novel targets for further investigation of the pathogenesis of PE and these differential miRNAs may be potential markers for the diagnosis and provide a potential therapeutic target for PE. Further investigations on posttranscriptional regulation in PE to evaluate biologic effects of identified miRNAs (including confirmations of miRNA and target gene interactions) are needed

Abstract

Cancer is a major health problem in both developed and developing countries. In women, cancer incidence rates increased every year. Developments in treatment modalities and the ability to detect tumours in the early stages increased their survival rate but also raise fertility problems. Those problems are the fertility preservation for patient who have to endure gonadotoxic chemotherapy and or radiation even though they still need their fertility functions. Ovarian cryopreservation and autotransplantation were initially designed to protect and restore reproductive function in patients receiving sterilizing chemotherapy and/or radiotherapy. Other indications including patients undergoing haematopietic stem cell transplantation, autoimmune diseases and those undergoing oophorectomy for non-cancer conditions. Options in cryopreserved ovarian tissues include autotransplantation and xenotransplantation. An orthotopic site or a heterotopic site can be considered for autotransplantation. Xenotransplantation of human ovarian tissue into immunodeficient animals can prevent immunological rejection.  The theoretical advantage of orthotopic grafts is the restoration of normal reproductive function and natural conception after transplantation but application for cancer patients is problematic because of the potential risk of transmission of microscopic metastatic disease. With Xenotransplantantion, the possibility of cancer transmission and relapse can be eliminated because cancer cells cannot penetrate the zona pellucida, and some technical difficulties of in vitro growth and maturation of primordial follicles can be bypassed. But it is still unknown whether conditions for the growth and maturation of human oocytes in an animal host are comparable to those in situ and whether animal pathogens can be transmitted to human tissue with it. Ovarian tissue cryopreservation is the fertility preservation option for prepubertal girls and for women who face thehigh likelihood of diminished ovarian reserve requiring immediate treatment. Its procedure are still within improvement and also in the study of understanding its mechanism. In the future, studies and large clinical trials are still needed to develop better cryoprotectants and cryopreservation protocols and also standardization - optimization transplantation techniques

Abstract

Squid is an economically important resource. Currently, squid populations, especially in the District Barru, were intensive exploited, that is feared to affect the population biology parameters. The study was conducted fromFebruary to April 2011. The sampling period was three times a week. The Samples were obtained using random collection from the fishermen catch using Rambo left net. Squid mantle length was measured to the nearest one mm.The parameters analyzed were age group, gonad maturity stage, growth, mortality, and exploitation rate. Squid population in Barru district consists of three age groups with the length of each mode of 51 mm, 98 mm, 133 mm formales, and 51 mm, 96 mm, 127 mm for females. The gonad maturity stage ranging from TKG I to IV for males and females, with the largest percentage of TKG TKG III (47.82% in males and 50.06% in females). The squid firstmaturity is reached at 94.3827 mm in long coat for males, and 59.6735 mm for females. Growth equation for males was Lt = 227 {1 - e -0.31 (t + 0.30)} and females are Lt = 196 {1-e-0, 37 (t +0.26)}. The total mortality rate (Z) is1.59 for males and 1.63 for females. The natural mortality rate (M) is 0.20 for males and 0.57 for females. The capture mortality rate (F) is 1.39 for males and 1.06 for females. The highest CPUE values reached in 1999 was 0.0022 ton per trip, while the smallest CPUE values reached in 2001 was 0.0001 tons per year. The greatest catches could be reached with fishing effort of 50 000 trips with catches of 50 tonnes.

Abstract

Tsunami devastated many water infrastructures including the wells. Tsunami areas, land use (rural and urban areas) and land management (agriculture land and home garden) can be leading heavy metals in water quality. The purpose of this research is to investigate how the Tsunami rehabilitation efforts affected the water quality of shallow groundwater by measuring the count of heavy metals (mercury, cadmium and lead by Atomic Absorption Spectrophotometer during the rainy and dry season. Forty-eight water samples’ of wells were collected to determine shallow groundwater from August 2007 to December 2007. The study includes interviews with the owners of the water facilities and sanitary inspection of shallow groundwater wells. The results show the presence Hg and most of Cd in well water are still below the regulatory acceptable limit by Ministry of Health R.I (2002). On the other hand, lead exceeds the regulatory acceptable limit

Abstract

This study aimed to determine the relationship between the method of delivery and the incidence of overweight or obesity during childhood. This study was conducted on June 2012 to March 2013 in four selected elementary schools in Iligan City, Philippines wherein 96 overweight to obese children between 5-8 years old were selected as respondents through purposive sampling technique. A descriptive-correlational research design was used. To gather the pertinent data and information, a researcher-made questionnaire was employed. The data gathered were then tabulated and analyzed using frequency and percentage distribution, Chi-square test and Spearman correlation coefficient. It was found out that there is no sufficient evidence to harbor a significant relationship between the method of delivery and the incidence of childhood overweight or obesity among the respondents. Thus, other factors should be explored to relate to overweight or obesity in childhood

Abstract

This study uses Aquaphotomics to measure Cadmium (Cd) and Magnesium (Mg) in aqueous solutions by analysing the changes in water spectra that occur due to water-metal interaction. Metals have no absorbance in the NIR spectral range, thus the methods developed so far have focused on detection of metal-organic complexes. Measurements were performed with Cd (II) and Mg(II) in 0.1 M HNO3, in the 680-1090 nm (water second and third overtones) and 1110-1800 nm (water first overtone) spectral regions, and were subjected to partial least-square regression analysis. Metal ions were scanned by NIRSystem 6500 using cuvette cell with 2 mm path length, in three consecutive days. Data for two days were used as data set and the rest of the data were used as prediction set. The calibration and prediction statistics obtained in this study indicated the potential of NIRS to predict metal ions in aqueous 0.1 M HNO3 solution with correlation coefficient (R2pred.0.7). The RPD (residual predictive deviation) or ratio of standard error of prediction to the standard deviation, values were greater than 2, indicating that the model is appropriate for practical use (Cozzolino,2007). By using water matrix coordinates (WAMACS) from regression coefficient, obtained a consistency specific wavelength for each　metal.. These results showed that the PLS model were able to detect character metal ions in the NIR region of electromagnetic spectra with high accuracy even at very low concentrations (0-10 ppm).
