A case is reported of right atrial myxoma presenting clinically as ascites and fever of unknown origin. An extensive work-up, including laboratory investigations, X-ray imaging, laparoscopy and laparotomy, failed to explain the clinical picture which was manifested post partum. Echocardiography was diagnostic and led to the curative treatment of surgical resection.

Colorectal cancer (CRC) is one of the most common diagnosis malignancies with different risk factors, including environmental and genetic. Several genes, called tumor suppressor genes, play an essential role in inhibiting these risk factors by preventing tumor development. One of these genes is somatostatin (SST). Somatostatin is an antiproliferative peptide with pro-apoptotic effects that enhance cell death to prevent tumor growth. This study aimed to investigate the association relationship between DNA methylation in SST promotor and colorectal cancer progression. After DNA bisulfite conversion, SST promoter methylation was examined using quantitative methylation‐specific PCR (qMSP) in 71 cases (19 metastasis CRC, 28 early-stage CRC, and 24 healthy controls). Quantitative methylation‐specific PCR (qMSP) is a real-time PCR method used to determine the unmethylated and methylated cytosine residues using a specific set of primers. The percentage of hypermethylation in SST promoter was 17%, 60%, and 79% for healthy controls, early-stage, and metastasis CRC groups. The results showed a significant association between DNA hypermethylation of SST promoter and CRC progression. P-values were 0.0364 for the early-stage group and 0.0138 for the metastasis group. The results also supported that the DNA hypermethylation block the expression of SST, which in turn induce carcinogenesis. The detection of SST promoter hypermethylation at early stage of cancer could be used as a biomarker for screening and prognosis of CRC.

Many developed countries around the world are currently competing to find low-cost, sustainable and clean energy sources. To replace conventional energy sources such as (oil, coal, etc.) for several reasons. mainly, because of the negative environmental impact of the Greenhouse Gas (GHG) emission problem. Also, these resources will deplete soon. As a result, seeking for a better replacement of fossil fuels either by converting to electric vehicles or by using other possible renewable energy sources with low (GHG) emissions is essential. Hydrogen is one of the primary potential future alternatives of current automotive petroleumrelated due to its high mass-energy ratio and abundance since it can be obtained from a broad spectrum of sources and by various techniques, such as anaerobic digestion from organic materials, rendering it a prospective target for safe and renewable energy. Hydrogen fuel stations are predicted to have a significant impact on the implementation of hydrogen as a fuel substitution on the worldwide fuel market, especially for heavy transportation. The primary objective of this innovative station branch is not only to promote the idea of hydrogen fuel on the vehicle fuelling industry but also to enhance the advancement of hydrogen fuel facilities while minimizing the danger to the investor. There are, though, some areas that need to be investigated with such drop-in facilities as storage and delivery mechanisms which this study covers. The key idea of such a system is to provide a safe, affordable and accessible car fuel source equivalent to conventional vehicle fuel on the industry, whether it is renewable. The primary goal of this research is to develop a secure, flexible and environmentally friendly hydrogen fueling facility, this design is regarded to be cost-efficient compared to other designs by at least 48 percent. Furthermore, this design showed encouraging signs concerning safety procedures and hazard evaluation where is ranked 6.8 on average out of 25 in the FMEA review assuring it’s safe further.

Objectives: The present retrospective study analyzed the spectrum of pediatric CNS tumors in a single tertiary hospital in Iraq. Methods: Data regarding frequencies of various primary CNS tumors (diagnosed according to the World Health Organization (WHO) classification), in pediatric patients (<18 yrs. of age), were collected from a single tertiary care hospital in Iraq for a period 2014-2017. Results: fifty-four children were diagnosed with primary CNS tumors. The most common primary pediatric CNS tumors were medulloblastoma (37%), followed by low grade gliomas (29.6%), high grade gliomas (0.011% ), CNS germinoma (0.09%), supratentorial primitive neuro-ectodermal tumors and ependymomas (0.037% for each). Rare tumors encountered were oligodendrogliomas, choroid plexus carcinoma, and pineoblastoma (0.18% for each). The most common low grade gliomas tumor was pilocytic astrocytoma. Conclusions: This is the first study reporting the spectrum of CNS tumors in children in Iraq. Except for a higher frequency of CNS germinoma, the profile of other pediatric CNS tumors in Iraq is relatively similar to that reported in other countries.
