المستخلص: The present study aimed to determine the levels of adiponectin and apelin and their relations with all parameters. Investigation in the present study included; hormones, lipid profile, liver enzymes activity and haematological profile in groups of Iraqi Basrah pregnant women during different months of pregnancy and to correlate these levels to maternal age, Body Mass Index, excepted parity and sex of fetuses and correlated with level of adiponectin and apelin hormones only and the results were compared with non - pregnant females as control group. The present study included (180) women ranging from 20 - 40 years old, out of them (70) pregnant and (20) non - pregnant women with polycystic ovary syndrome (PCOs), and (90) females non - pregnant were considered as control group. The pregnant women attended the obsteric units in the general state hospitals in Basra Governorate. They are as follows : Al - Basra General Hospital for Maternity and Childhood, Al - Mawane, Al - Fayha’a and Basra General Hospital which drain most patients from urban and rural areas. None of the selected women suffered from any type of disease. Required data were collected by the researcher depending on direct interview with women before being admitted to the study, using a questionnaire including information on age, parity, month of pregnancy, and geographical area..The Women were divided into two age group (≤ 27 and ≥28 years). Moreover, females were also divided according to BMI into normal (≤ 25), over weight (25 - 30) and Obese (≥30).The month of gestation was determined not only from the date of the women’s last menstruation (LMP) but also according to the ultrasonic reports that pregnant women had. Blood samples (10 ml) were taken from pregnant women at the end of each month of pregnancy and from control group as well as from women with PCOs. Each blood sample was divided into EDTA tube (2 ml) which was used for complete hematological picture study (RBC, Hb, PCV, PLT, WBCs count and WBCs differential count) and the plain tube (8 ml) where the serum was obtained, for biochemical study (Adiponectin, Apelin, testosterone, Progesterone, estradiol, follicular stimulating hormone, luteinizing hormone, insulin, lipid profile and liver enzymes).The results indicated that maternal age had no significant effect on the level of adiponectin, apelin, FSH and LH hormones, while the study showed a significantly effect on level of progesterone, estradiol, testosterone and insulin hormones between pregnant and non - pregnant women. Adiponectin levels decreased in pregnant and non - pregnant females with increased body mass index whereas apelin, estradiol, progesterone and insulin levels increased. When the comparison between pregnant and non - pregnant women was done, a decrease in adiponectin and apelin was noticed. Accompanied by an increase in the level of estradiol, testosterone, progesterone and insulin hormones in pregnant women compared to non - pregnant women.Women with PCOs showed low levels of both Adiponectin and apelin with high levels of Testosterone and Insulin.Results also revealed that age had no effect on total cholesterol, triglycerides, and HDL, in both pregnant and non - pregnant females, but when the BMI was taken in consideration, high levels of these parameters were found in - group of BMI (obese). In addition, the present study showed that age had no effect on liver enzymes (AST and ALT) while ALP showed that the behavior increased up as a different high body mass index in pregnant women, in comparison with the control group. However, ALP activity also increased in high BMI group.Hematological study showed that age had no effect on RBC, Platelets, and hematocrit. Similar results were found when BMI was taken in consideration. Total WBCs showed a non - significant increase in pregnant women as compared with the control group. Adiponectin levels were significantly higher in pregnant females carrying female fetuses compared to those with male fetuses, while the other hormone apelin did not differ between the two groups. The Result of the present study revealed that adiponectin was significantly decreased as apelin was significantly increased with the increased parity.

The injection of nitrate (NO3) and nitrite (NO2) promotes the growth of nitrate reducing bacteria (NRB) which outcompete (SRB) on carbon sources. A total of 40 samples were collected from produced water of oil production facilities in Basra including Nahran Omer and Al - Lahis oil fields in a period time of 6 months from August 2013 to January 2014. Mix cultures of (SRB) and (NRB) were isolated from these samples, the two types of bacteria were enumerated by using most probable number method, the results show that the numbers of both bacteria were generally quite low, the viable count of (SRB) was between 4 - 7cell/100 ml whereas the (NRB) was between <2 - 4 cell/100 ml. This study also includes purification of isolates for both (SRB) and (NRB) and the genetic identification by polymerase chain reaction (PCR) technique through which the universal 16S rRNA gene of 1500 bp is amplified and sequenced for identification to the level of strains. Microbial community analysis showed that isolates of (NRB) were have identity of 99% Pseudomonas stutzeri, P. putida, Herbaspirillum huttiense and Bacillus licheniformis while isolates of (SRB) were have identity of 99% Shewanella hafniensis, Desulfosporosinus orientis and Desulfotomaculum acetooxidans with supposing that all isolates new world strains. The results of the treatment with nitrate or nitrite showed a strong inhibitory effect on (SRB) growth and (H2S) production, sulfide levels do not increase at all concentrations (200, 400, 600, 800 and 1000) mg/l of nitrate or nitrite range between 4.2 - 21 mg/l in treatment with nitrate and 5.2 - 23 mg/l in treatment with nitrite. This is consistent with the concentrations of bacteria in all treatment bottles which range between 0.001 - 0.26 and 0.003 - 0.17 in treatment with nitrate or nitrite respectively, while there is a significant increase in sulfide 121 mg/l and concentration of bacteria 0.84 in control as optical density. (NRB) has a certain inhibitory effect on the growth of (SRB) and (H2S) production when the (NRB) nutrient (nitrate or nitrite 200, 400, 600, 800 and 1000) mg/l were adding , the activity of (NRB) increases after treatment, and it consumed all nitrate or nitrite during 2 - 3 days of incubation, the strong inhibition of (H2S) production is at concentration 1000 mg/l of nitrate where the results showed that there was significant decrease in sulfide level 34 mg/l and number of bacteria, 34.8 cell/ml during 10 days of incubation.Souring control at long term treatment in bioreactors show sharp decrease in production of (H2S) to 94% after injection of nitrate and nitrite during the period of 60 days, the continuous dosing of nitrate and nitrite (333 mg/l/day nitrate and 133 mg/l/day nitrite) inhibited the metabolic activity of (SRB) and (H2S) production severely, the sulfide levels decrease from 155 to 10 mg/l and number of (SRB) from >1100 to 3.5 cell/ml the percent in number decreased was to 99.6%, at the same time activity and numbers of (NRB) increase from 1100 to >1100 cell/ml over the duration of experiment. The results of corrosion rate measurement on mild steel after 60 days showed that the highest corrosion rate was 70.7 mg/cm2/year in control reactor while the lowest corrosion rate was 15.8 mg/cm2/year in treated reactor at the same period time of exposure with percent of decreasing in weight loss to 55% comparing with control reactor.

المستخلص: Bacillus thuringiensis (commonly known Bt) is a ubiquitous, gram - positive and spore - forming bacterium. The organism produces intracellular crystal proteins, which are toxic to insects, during the stationary phase of its growth cycle. Because of its insecticidal activity, B. thuringiensis has been used as a biopesticide. However, it is still necessary to search for more toxins to control insect orders, which have the ability to develop resistance against such pesticides, and also to provide alternatives for chemical insecticides. The purpose of this study is to isolate B. thuringiensis strains that are collected from Basrah, and to identify the cry genes content of these isolations.In this study, 344 Bacillus species were isolated from 22 soil samples collected from different area from Basrah, fifty six of them (16,2%) were identified as B. thuringiensis strains based on colony morphology , microscopic observation of spore position in the cell and genetic analysis . Most isolations were examined by multiplex PCR using for cry 1, cry 2, and cry 9 universal primers in order to identify the type of cry gene content of these isolations. 82% of the isolations amplified cry1 gene, 76% amplified cry9 and 21% amplified cry2 genes.In this study cloned cry1I gene is using specific primer to amplify full length of gene. The cry 1I gene (2169 bp) amplified product was inserted in to the Pst1 and BamH1 sites of pdrive cloning vector joining technique to produce the recombinant vector. The cloning vector then transformed in to E.coli HB101 and the transformant cells colonies were selected by ampicillin sensitive phenotype, the efficiency of transformation was also determined to be 7,8 ×105cfu/μg. After that the cry1I protein is purified from LB broth media supported with ampicillinand used this protein against Tuta absoluta larva within concentrations (100 μg/ml, 150μg/ml, 200μg/ml) .The effectiveness of the toxin is to kill the larvae were in the concentration of (200μg/ml) in the 24 hours after treatment, while least toxicity in the concentration (100μg/ml) need three days to kill all larva.
