Abstract

A pap test is a simple technique which can detect pre-cancerous and cancerous cells in the vagina and cervix. Cervical cancer is the easiest gynecologic cancer we could prevent it, with regular screening tests and follow-up this screening may avoid cervical cancer or detact it early.This study aims to estimate cytological changes and precancerus lesions during Pap smear test and visual inspection of the cervix on Iraqi women and determine the relationship with demographic characteristics. The study included 50 women aged 18-56 years (mean 39 ±10) in National Cancer of Research Center (NCRC) belong to Baghdad University. These women suffered from genital problems or for checking reproductive health status during the period from 1stDecember 2016 to 31stApril 2018 to perform the grossly inspection of the cervix and take papanacola smear. The results showed that 98% of the women were sexually active, 88% of them in premenapusal period and only (12%) in postmenapusal. Visual inspection of the cervix showed there were (40%) erosion lesions, cytology examination showed (90%) of non specific inflamation, 60% of reactive squamous metaplasia, 26% Koilocytotic atypia, 16% CIN1 or LGSIL. Women how used the contraception 68% and the most of them used pills. The women who had multiple births 26% , 18% had one, and 56 % were nulliparous . The causes of the visit were variable as for rotine checking 48% or to know the reason of abnormal vaginal discharge 22%. 46% of them were doing this test while 54% of them didn't make it previously. Therefore, we recommend by firm awareness and must perform pap smear screening for sexually active women to prevent precancereus lesions in the cervix and then avoid cervical cancer.

Abstract

With the growing number of patient’s being diagnosed with Parkinson’s disease and Multiple Sclerosis each year it is becoming ever more important to find the cause for these neurological disorders. The present study attempts to shed light on one of the factors that may play a role as a causative agent in these neurological diseases by finding a correlation between the Herpes simplex virus type 1 and 2 in patients with Parkinson’s disease and multiple sclerosis by detecting the virus in these patients using immunological techniques. Sixty patients with neurological diseases (40 patients with Multiple sclerosis and 20 patients with Parkinson’s disease) who’s ages ranged from (17-76) years have been investigated. Samples were collected during the time period between November 2017 and April 2018 and compared to twenty five apparently healthy individuals as a control group. All the studied groups were measured for herpes simplex virus type-1 IgM and herpes simplex virus type-2 IgM by using the enzyme linked immuno sorbent assay. The results of the present study showed that there was a highly significant difference (p<0.01) in the concentration of IgM HSV-1 and HSV-2 in the sera of patients with MS and PD compared to the control group, While there was a none-significant difference (p>0.05) in the concentration of IgM HSV-1 and HSV-2 according to the gender. Thus, there is a likely possibility the HSV could be a contributing factor in the activation of some neurological diseases by the means of initiating an autoimmune reaction against the host’s nerve cells. The nerve cells have proteins that resemble portions of the virus from a structural and genetic stand point.

Abstract

Normally, bacteria exposed to antibiotics at sub minimal inhibitory concentrations (MIC) inside the host. Therefore, the current study aimed to comprehend the association among hemolysins, biofilm, as well as gentamicin resistance in local MRSA isolates. Around 35 Staphylococcus aureus locally isolated from different clinical specimens were employed in this study. Methicillin resistance was detected via cefoxitin disk diffusion and mecA amplification methods. MIC of gentamicin was estimated by broth microdilution method. Hemolysin genes involving hla, hlb, hld, and hlg were determined using multiplex polymerase chain reaction (PCR) technique. Microtiter plate method was employed for biofilm assessment in the presence and absence of gentamicin at sub MIC. Moreover, atomic force microscopy technique was employed for confirming the effect of gentamicin on biofilm. The present findings revealed that methicillin resistant S. aureus (MRSA) constituted, nearly, 94.29% (33 isolates) of all S. aureus isolates. Around 12 (36.36%), four (12.12%), and 17 (51.51%) isolates were gentamicin-sensitive, intermediate, and resistant to gentamicin, respectively. hla and hld were located in 32 out 33 MRSA isolates. All MRSA isolates succeeded in forming biofilm; however, three (0.09%), 23 (69.69%), and seven (21.21%) isolates formed weak,moderate, andstrong biofilm, respectively. Gentamicin at sub MIC reduced the intensity of biofilm and the AFM confirmed this finding. In conclusion, very weak correlation linked the biofilm formation capacity and isolate MIC. On the other hand, possession of hemolysin genes seems has no correlation with biofilm formation. Nevertheless, gentamicin at sub MIC reduced the intensity of MRSA biofilm.

Abstract

Background: Noise injury and hearing loss are significant problems in Nigerian community. The hearing loss sustained from noise injury can have disabled personnel and social consequences for the affected persons and their families. This study was carried out to quantify the noise level of over eighty (80) different sources using the sound level meter (GB: 2266204) at different locations in Akure, capital of Ondo State, Nigeria. Standard procedure specified by the manufacturer was strictly followed and the results were statistically analyzed. The range of results obtained were: household products (48.5±0.5 - 105.7±3.2dBA), traffic (60.9±0.6 - 77.5±1.2dBA), market (55.0±0.5 - 68.1±0.7dBA), automobile/ workshop (65.7±0.5 - 105.7±3.3dBA), poultry/livestock (48.7±0.5 - 60.7±0.7dBA), musical instrument (45.0±0.5 - 79.3±1.3dBA), residential areas (41.2±0.5 - 46.3±0.5), farm machinery/tools (76.4±1.2 - 99.3±1.5dBA), hospital (48.0±0.5 - 61.1±0.6dBA), and baby toys (42.7±0.5 - 50.9±0.5dBA). The results showed that many of the sources exceeded the standard limits proposed by WHO, FEPA, OSHA and that of countries like Germany, Australia, Japan, Korea, and the Philippines. Conclusion: The results show the existence of noise pollution in Akure, thus the need for noise control in this area. It is recommended that the Nigerian government should put an effort to reduce noise pollution in the country. This can be achieved by creating awareness of the danger of noise pollution and putting up necessary sanctions.

Abstract

Copper plasma is generated with the existence of an external magnetic field and without its presence utilizing Nd:YAG laser (1064 nm ,9 ns) in different pulse laser energy which ranges from(100 to 400) mJ in a vacuum. Plasma parameter beta (β) is least than 1, this indicates that the existence of magnetic field confinement effect is proven. Note that both the electron temperature and electron density increases with the laser pulse energy increasing , Both are higher in the presence of a magnetic field.

Abstract

Nanocrystal-ZnS-loaded graphene was synthesized by a facile co-precipitation route. The Graphene was affected on the characterization of ZnS which has been investigated. XRD results reveal that ZnS has a cubic system while the hexagonal structure has been observed by loading graphene during preparation ZnS. D.c-conductivity proves that ZnS and ZnS/Gr have semiconductor behavior. The sensing properties of ZnS/Gr against NO2 gas were investigated as a function of operating temperature and time under optimal condition. The sensitivity, response time and recovery time were calculated with different operating temperatures (100, 150, 200)oC.

Abstract

Isotope tracer methods were used to determine flow paths, recharge areas, and relative age for groundwater in the Ameriyat Al- Falluja Al-Anbar governorate. The isotope of surface water and groundwater in the Ameriyat Al- Falluja area was assessed using a stable isotope technique. Data stable isotope parameters (2H and 18O) for three surface water and five groundwater samples were detected. The comparison of hydrogen and oxygen isotope compositions between groundwater and Euphrates River water demonstrated that the composition of the hydrogen and oxygen isotopes from Euphrates River matched that of the local meteoric water. This indicated that rainfall is the primary source of the river water. Environmental Isotopes results show that the surface water and groundwater originates from direct leakage through permeable beds. There is an interaction between Euphrates and groundwater wells in the study area except in the W1 and W5 wells sites.

Abstract

This study deals with the application of surface-consistent deconvolution to the two-dimensional seismic data applied to the Block 11 area within the administrative boundaries of Najaf and Muthanna Governorates with an area of 4822〖km〗^2, the processed seismic data of line (7Gn 21) is 54 km long. The study was conducted within the Processing Department of the Oil Exploration Company. The gap surface- consistent deconvolution was applied using best results of the parameters applied were: The length of the operator 240, the gap operator 24, the white noise 0.01%, the seismic sections of this type showed improvement with the decay of the existing complications and thus give a good continuity of the reflectors at the expense of resolution.Then, spiking surface- consistent deconvolution was applied using the best implementation parameters chosen during the test: operator length 240, gap operator 4, and added white noise 0.01%. This type gave a better estimate of reflectivity in seismic sections with good resolution and loss of continuity compared to gap surface- consistent deconvolution. The application of surface-consistent deconvolution to seismic data showed a significant improvement in data quality by reducing random noise, eliminating variability in emissions due to near-surface irregularities, and improving the estimation of statistics.
