Preparation and Characterization of New Imidazole Derivatives Derived From Hydrazones and Study of their Biological and Laser Efficacy
No full textThis research aims to synthesize and characterize imidazole derivatives from the reaction of hydrazones with amino acids (glycine and alanine) using conventional methods. The validity of the synthesized compounds was confirmed through physical measurements such as melting point and color, as well as spectroscopic methods such as infrared spectroscopy and proton nuclear magnetic resonance spectroscopy. The research methods included testing the biological effectiveness of the compounds against two types of bacteria: Gram-positive Staphylococcus epidermidis and Gram-negative Klebsiella pneumoniae. The compounds (M11-M15) were also irradiated using a neodymium nanosecond laser system (Nd laser) with a wavelength of 808 nm and a frequency of 5 Hz. Changes in melting point and color were measured after irradiation. The results showed that the synthesized compounds exhibited significant antibacterial activity against both types of bacteria. Additionally, some compounds demonstrated high stability under laser irradiation, while others experienced changes in melting point and color, indicating alterations in bond structures

It was also found from examination scanning electromagnetic (SEM) that it has a spherical shape with nanometer sizes reaching less than 20 nanometers, when the test of Zeta potential(Z-potential) proved sliver Nano particles were stability. From the biological side, Nano silver has proven its ability to inhibit bacteria from diffusion
Comparing Warm and Cold Bupivacaine for Cesarean Section Spinal Anesthesia
No full textSpinal anesthesia is widely favored for cesarean sections due to its benefits over general anesthesia, but shivering remains a common issue. This study compares warm and cold storage of heavy bupivacaine for spinal anesthesia in cesarean delivery. One hundred parturient women were divided into groups receiving warm or cold bupivacaine, and vital signs, shivering, and block duration were assessed. While no significant differences were found in vital signs or block duration, shivering incidence was notably higher in the cold bupivacaine group. These findings highlight the importance of considering the temperature of local anesthetic solutions to mitigate shivering, indicating a need for further exploration of contributing factors. Optimizing bupivacaine temperature may enhance patient comfort and safety during cesarean sections. Further research could elucidate the multifactorial nature of shivering during spinal anesthesia, improving obstetric anesthesia practices
Applying Inductively Coupled Plasma Optical Emission Spectroscopy to Determine Trace Elements in the Blood of Workers in Radiation Sources
No full textExamining the long-term effects of radiation on workers necessitates taking into account the parameters where even minor adjustments may have a significant impact on the biological system. In this regard, we believe that body trace elements play essential functions. The objective of this study was to examine how occupational exposure affected blood trace element concentrations. in the blood of (30) employees of the Iraqi Radioactive Resources Control Authority who had a deal with radioactive sources, in addition to (20) other administrators working in the central laboratories of the Iraqi Atomic Energy Commission as a control group, had not a history of radiation exposure, the analyses were carried out using optical plasma emission spectroscopy coupled to induction (ICP-OES). All employees and administrators are between (30-64) years old and have worked for at least (15) years. The study was conducted in the Directorate of Central Laboratories at the AL-Tuwaitha site in Baghdad. The study found a significant reduction in iron, and zinc levels among radioactive sources body workers in contrast with the control group, and found a significant increase in Cu in the employees compared with the control while no significant change was observed in manganese and selenium levels. Furthermore, the quality and confidence interval across the future operating characteristics curve was estimated. Specificity and confidence interval of 95% were estimated via the receiver operating characteristic curve (ROC). At the same time, serum manganese level (p-value 0.001) decreased proportionately with longer exposure times, which also showed statistical significance. Age and manganese levels were significantly correlated, but there was no association with the other trace elements. The study provided conclusive evidence of disturbances in the amounts of trace elements in the blood of workers in the Radioactive Sources Authority, which makes them more susceptible to many diseases due to their radiation exposure There was a correlation between trace element disturbances and increasing serving years, which portends the use of more preventive measures and adherence to the principles of radiation protection protocols to reduce the effects of radiation exposure
Preparation and Characterization of New Rings of Oxazine Derivatives and Studying Their Biological and Laser Effectiveness and Molecular Docking
No full textThe study included the preparation of new hexagonal rings by reacting the prepared chalcone with urea by sublimation and verifying the validity of the prepared structures using physical measurements such as color and melting point. For example, infrared spectroscopy, proton, and carbon NMR spectroscopy were also tested for bioavailability against two types of Gram- positive and Gram-negative bacteria Using MOE software (2009), the molecular docking of a few produced drugs against E. coli was investigated. The laser activity of some of the prepared compounds was measured using a helium-neon laser device (visible laser), where each compound irradiated the prepared compounds for four times (15, 30, 45, 60) seconds
Preparation and Diagnosis of New Complexes for Hg (II) With 4-Amino Acetanilide And (Dppp) As A Ligand And Study Of The Bacterial Efficacy And Molecular Docking Of The Prepared Complexes
No full textMercury complexes are increasingly important for antibacterial action, hence novel Hg complexes were created using 3-aminoacetanilide (L) and dppp. The mercury complex has the formula [HgL2]Cl2, whereas phosphine complexes have the formula [HgL2(dppp)]Cl2. The properties of the produced compounds were determined using FTIR, 31P-NMR, and 1H-NMR. Furthermore, this study concludes the evaluation of the biological activity of prepared complexes against two bacterial species, Pseudomonas aeruginosa (gram-positive) and Citrobacer Freundii (gram-negative), using the Agar well method. The prepared complex [HgL2(dppp)]Cl2 showed greater activity against Pseudomonas aeruginosa than Escherichia coli"
Utilization of Geographic Information Systems (GIS) to Evaluation of Hydrogeological Conditions, to the west Kirkuk secondary basin, Northern Iraq
No full textThe surface drainage network of the basin was derived using the (ArcGIS 10.3) software from a Digital Elevation Model (DEM) with a spatial resolution of (10x10) m per cell. The total stream order within the basin was six, with the number of streams varying across different orders. Other aspects of the hydrogeology of the West Kirkuk secondary basin were also investigated. Groundwater level contour map was developed from (23) wells data. This made it possible to map the flow net of the groundwater which demonstrated that the direction of water movement in the study area was from the northeast to the southwest. this is in line with the topographic gradients of the region in question. The hydraulic properties were also evaluated based on pumping rate data and groundwater level drawdown measurements from 8 out of the total number of wells. It was observed that the values of the transmissivity coefficient (T) ranged between ( 7.28- 31.47)m2/day, while the values of hydraulic conductivity (K) ranged between (0.10- 0.44) m/day
