Frequent hypomethylation of PTGS2 gene promoter in human term placenta

Background: Gene expression profiles of several tumor suppressor genes are regulated by the methylation and demethylation of their promoters. Here, we aim to identify and quantify the methylation status of four tumor suppressor genes from placentas at term and compare them with the maternal white-blood-cells. Methods: In order to achieve this objective, DNA enriched from twenty placentas at term and maternal white blood cells was bisulfite-converted and amplified using quantitative real-time methyl-light polymerase chain reaction for the four-genes studied (RASSF1A, APC, RAR-beta, and PTGS2). Results: Among the four genes examined, RASSF1A, APC and RAR-beta promoter regions were hypermethylated in all the placental samples compared with maternal WBCs. Strikingly, PTGS2 was found to be hypomethylated in the placentas compared to the maternal cells. Conclusion: Since placental DNA represents fetal methylation profile and it is an established fact that there is certain amount of cell free circulating DNA in human plasma/serum, these data strongly suggest that hypermethylation of RASSF1A, APC and RAR-beta can be used as gender independent biomarkers to distinctly identify placental DNA in maternal blood. In addition, this is the first report which demonstrates hypomethylation of PTGS2 locus which may have important clinical implications e.g. placental abnormalities

IMPLIKASI TEORI BUNGA TERHADAP MANAJEMEN KEUANGAN DALAM PERSPEKTIF EKONOMI ISLAM

This study aimed to describe the implications of the theory of interest to financial management. Results of the description viewed from the standpoint of Islamic economics. The implication variable that really stood out are theory of interest; interest philosophy, the concept of interest and usury, the concept of money, the concept of time value of money and the economic value of time, the concept of cost of capital, and interest as a revenue. The variables  in financial management implicated by of the theory interest are the general economic, investment, pricing, inflation and money supply, economic growth, unemployment, social welfare and exchange rate. This study is a literature research (library research), which is using books as a source of data to explain the issues studied. The character of this study is descriptive qualitative research that  describe and analyze the data clearly on the theories of interest and their implications to financial management on the Islamic economics perspective. Source of data used in this research is secondary data, ie data obtained from the study of literature in the form of analysis of books, papers and websites. According to the type of data that is required of the study, the data analysis technique used is the technique of "content analysis" which is a method of data analysis that focuses on the content of an object of study. In addition to using content analysis method, the author also uses several methods of approach, namely: Deduction Approach,  Induction Approach and Comparison. From the discussion, this study found strong implications of the theory of interest to financial management, and after review of the economic point of view Islam concluded there is a negative impact on the economic system of conventional, for example, that in fact the theory of interest is the intervention of theoretical biology, so it is considered living creature that is about living cells, the concept of money, it is not clear status; instrument or commodity?, The interest is riba, time value of money is not rational, the right is economic value of time, including capital costs and the interest is considered as an income. The findings impact to the financial management so that the economic system is not clear (absurd)

Sediment quality index in mangrove forest

The objectives of this review are to determine the types of indices to use, to assess the current sediment quality index (SQI) of a mangrove forest and to select the appropriate index to describe the mangrove sediment quality index. Amongst the many indices considered in this review are the enrichment factors (EFs), the geo-accumulation index (Igeo), the pollution load index (PLI), the marine sediment pollution index (MSPI) and sediment quality index (SQI). The different indices give diverse perspectives of the status of mangrove sediment quality. This review also highlights the appropriate parameters that need to be used in assessing sediment quality, such as the physical, chemical and biological properties. As the comparison review, the sediment quality can be utilized for Mangrove quality index (MQI) development like to assess the heavy metal, complete laboratory parameters and a classification following the Interim Sediment Quality Guidelines ISQG, PCA and HACA. For the heavy metal content of sediment, the suggested parameters are Pb, Zn, Cu, Co and Mn. Lastly, for the indices, the enrichment factor (EFs), geo-accumulation index (Igeo), pollution load index (PLI) and marine sediment pollution index (MPSI) are used in develop SQI on mangrove forest

Epidemiology and outcomes of out-of-hospital cardiac arrest in a developing country-a multicenter cohort study.

Background Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of death and disability worldwide. Overall survival after an OHCA has been reported to be poor and limited studies have been conducted in developing countries. We aimed to investigate the rates of survival from OHCA and explore components of the chain of survival in a developing country. Methods We conducted a multicenter prospective cohort study in the emergency departments (ED) of five major public and private sector hospitals of Karachi, Pakistan from January 2013 to April 2013. Twenty-four hour data collection was performed by trained data collectors, using a structured questionnaire. All patients ≥18 years of age, presenting with OHCA of cardiac origin, were included. Patients with do-not-resuscitate status or referred from other hospitals were excluded. Our primary outcome was survival of OHCA patients at the end of ED stay. Results During the three month period, data was obtained from 310 OHCA patients. The overall survival to ED discharge was 1.6 % which decreased to 0 % at 2-months after discharge. More than half (58.3 %) of these OHCA patients were brought to the hospital in a non-EMS (emergency medical service) vehicle i.e. public or private transportation. Patients utilizing non-EMS transportation reached the hospital earlier with a median time of 23 min compared to patients utilizing any type of ambulances which had a delay of 7 min hospital reaching time (median time 30 min). However, patients utilizing ambulances with life-support facilities, as compared to all other types of pre-hospital transportation, had the shortest time to first life-support intervention (15 min). Most of the patients (92.9 %) had a witnessed cardiac arrest out of which only a small percentage (2.3 %) received bystander CPR (cardio pulmonary resuscitation). Median time from arrest to receiving first CPR was 20 min. Only 1 % of patients were found to have a shockable rhythm on first assessment. Conclusion This study showed that the overall survival of OHCA is null in this population. Lack of bystander CPR and weaker emergency medical services (EMS) leading to a delay in receiving life-support interventions were some of the important observations. Poor survival emphasizes the need to standardize EMS systems, initiate public awareness programs and strengthen links in the chain of survival.

Oxygen Reduction Reaction Mechanism on the Square Paddle-Wheel Cage Site of TM-BTC (TM=Mn, Fe, Cu) Metal Organic Framework

We study the oxygen reduction reaction (ORR) mechanism on the square paddle-wheel cage active site of TM-BTC (TM= Mn, Fe, Cu) metal organic framework by using a combination of DFT and microkinetic calculations. By using a small cluster for modeling the TM-BTC active site structure, we have successfully reproduced the experimental trend of ORR activity on the TM-BTC systems: Mn-BTC > Fe-BTC > Cu-BTC. We also show that the unusual ORR activity trend from experiments for Mn and Fe systems is originated from the strength of OH adsorption on these systems. Mn-BTC system has better ORR activity than the Fe-BTC system because it has weaker OH adsorption. A very strong OH adsorption makes the final OH reduction step become more sluggish, and hence hindering the ORR process
