Organic Geochemistry of Tanjero Formation at Dokan and Shaqlawa, Northern Iraq
type: item
description: Late Campanian - Maastrichtian Tanjero Formation at Dokan and Shaqlawa areas was studied to determine its hydrocarbon-generation potential and depositional environment conditions. For this purpose, seventeen samples were subjected for Total Organic Carbon (TOC) and Rock-Eval pyrolyis analyses. Bitumen was extracted from three samples and analyzed by GC-FID. Generally, TOC and S2 values of Tanjero Formation are low (0.07-0.54 and 0.01-0.53; respectively); indicating they have low potentiality for hydrocarbon generation. Rock-Eval pyrolysis parameters (hydrogen index, oxygen index, and Tmax) indicate that the Tanjero Formation clastics contain mainly type IV and III kerogen. Pristane/phytane values indicate that the Tanjero Formation was deposited under oxic environment. Weathering (especially oxidation) reduced the TOC, the potentiality of the formation rock, and the Extractable Organic Matter (EOM) values.

Updated stratigraphy, tectonics and boundary conditions of the Mawat and Bulfat Ophiolite Complexes, Kurdistan Region, NE-Iraq
type: item
description: The Mawat and Bulfat Igneous Complexes are two neighboring areas in the extreme northeastern Iraq near the border with Iran. Each complex has about 250 square kilometers in surface area and their stratigraphic and tectonic settings are nearly identical. These settings are established in the seventieth of the last century and since that time no significant changes are introduced till now although tens of the studies achieved on them. Here we introduce dramatic changes in the stratigraphy and tectonics of the two complexes depending on field mapping, eye witness and correlations in addition to applying petrographical, paleontological and boundary conditional studies. The two igneous complexes are changed to metamorphic core complexes by changing the previous ophiolite to metamorphosed greywackes and volcaniclastic sandstones. Additionally the previous three allochthonous sheets are considered to be autochthonous sedimentary stratigraphic units which include non-metamorphosed greywackes and limestone (Walash-Naoperdan Series) metamorphosed greywackes (previous ophiolite sheet) and metamorphosed Naoperdan Series (previous Gimo thrust Sheet). The deposition timing, source areas and their relation with other units of the Paleocene-Eocene are clarified and their boundaries are changed from tectonic to depositional. These attributes are linked with historical development of Sanandij-Sirjan Zone as the main part of Neo-Tethys sedimentary basin. It is concluded also that these sedimentary rocks are buried deeply during Late Eocene and metamorphosed regionally then uplifted as Core Complex during Pliocene bringing up with them self- Cretaceous units such a Shiranish Formation.

Parasitic stages contaminants of some vegetables selected from super and local markets of Kirkuk city, Iraq
type: item
description: Vegetables are essential components of a healthy human diet but their raw administration is an important means of transmitting many infectious diseases. From October 2018 to May 2019, this study was intended to detect the parasitic pollutants in some common green vegetables used for fresh intake in Kirkuk city's super and local markets. On the basis of Kirkuk city's geographical division, four areas were selected: Rahim-awa, Huzairan-one, Wassiti and Ras Al-JisrJisr. Eight types of vegetables from each region were collected including tomato, lettuce, cucumber, radish, celery, leek, cabbage and basil. Parasitic stages were microscopically detected by direct smear or by Iodine staining or modified Zeihl-Neelsen stain. Many parasitic stages (eggs, oocysts, and cysts) have been found contaminating the vegetables. In general vegetables were more contaminated with parasitic stages in local markets than in supermarkets. Entamoeba histolytica was the most common parasite detected at 21.1 % frequency. Followed by Giardia lamblia, Cryptosporidium parvum, Hyminolepis nana, Echinococcus granulosus and Microsporidia sp., with 12.8 %, 5.4%, 4.2%, 3.5 % and 2.3 % for all parasites respectively. Radish, celery and leek were more commonly contaminated than cucumber, tomato, lettuce, basil and cabbage. In Ras Al-Jisr, the highest rate of contamination was detected, followed by Huzairan-one and Wassiti, the lowest rate was detected in Rahim-awa. The conclusion is that, vegetables are more contaminated with parasitic stages in Kirkuk's local markets than in supermarkets. Parasites were found contaminating radish, celery, and leek more than cucumber, tomato, lettuce, basil and cabbage. The greatest isolated pathogenic parasites were the Entamoeba histolytica and the Giardia lamblia cysts. Multiple contaminated parasites have been observed in almost all vegetables.

The effect of some antibiotics and antiseptics on several bacterial genera isolated from the animal house
type: item
description: From different places of animal house (University of Baghdad/ biology department/ college of science), that include cages of (rats, mice and rabbits), walls, float, counters and sinks, the specimens were taken by using 25 sterile swabs. The kinds of isolated bacteria were identified according to the morphological features, biochemical tests and by VITEK2 system. fourteen strains were isolated belonged to Pseudomonas aeruginosa, Pseudomonas luteola, Escherichia coli, Klebseilla pneumoniae and Staphylococcus aureus. Susceptibility test were done by using VITEK 2 AST, P. luteola was showed sensitivity to most antibiotics but resistant to Cefazolin and Trimethoprim/ Sulfamethoxazole, but other gram negative bacteria were resistant to most antibiotics but sensitive to Gentamicin, Tobromycin, Ciprofloxacin. While gram positive bacteria (S. aureus) were detected as VERSA and MRSA, while sensitive to (Gentamicin, Tobramycin, Levofloxacin, Moxifloxacin, Linezolid, Nitrofurantoin, Tiglycine). While MIC determination of disinfectants such as, absolute alcohol, and bleach were made for the isolated bacteria by macro-dilution method. The highest MIC value against P. aeruginosa from alcohol was 64 mg/ ml. while the lowest MIC value of it was against K. pneumoniae, Staphylococcus aureus. On other hand the bleach gave the higher MIC value was against S. aureus, P. aeruginosa 25 mg/ml, 16 mg/ml respectively. But the lowest MIC value against E. coli. We were concluded that many pathogenic bacteria can be isolated from animal house and common between humans and animals and can cause diseases to workers and researchers in animal house. They must take the necessary precautions such as sterilization of various antiseptics to avoid infection with pathogenic bacteria.

Evaluation of Circulation Levels of ASA and IL-6 in Infertile Men
type: item
description: The elevated levels of ASA and IL-6 antibodies in semen have a fundamental role in immune sterility, so the current study was designed to compare the blood serum levels of these markers between infertile and healthy men. Serum levels of ASA and IL-6, of 46 infertile and 44 fertile males were assessed using ELISA test (standard curve). The findings showed that mean serum IL-6 and ASA levels were significantly higher in infertile male compared with control (107.4 pg/ml, and 51.4 U/ml, VS 8.3 pg/ml, 11.50 U/ml at P≤ 0.01). According to the types of infertility the result also showed there was a significant statistically difference in the level of IL-6, and ASA within comparted groups. These data concluded that the significant increase in serum ASA and IL-6, compared to the lower levels in the control, indicating that these markers may be implicated in the pathogenesis of male infertility.
