Malignant renal neoplasm: Because benign tumors of kidney are rare, so it is a good rule that all neoplasm of kidney which are recognized clinically should be treated as malignant. They are uncommon between the ages of 7&40(l).Rcna! cell carcinoma is the most common tumor of the kidney in adult. It arises from renal tubular cells.. It is rare in children &is more frequent in men than women. It is an adenocarcinoma &is the most common neoplasm(75%) of kidney. The tumor may invade loca!Iy& metastasize by way of blood stream &the lymphatics. Regional lymph nodes are involved in approximately 30% of patients, unfortunately sign &symptoms are usually meager until the disease is advanced. Gross haematuria is the most fr

Background: the immune system differentiates between the endogenous and exogenous bodies that inter the body. The break-down of blood-testis barrier results in the production of antisperm antibodies. This may occur in the case of an infection to the prostate, seminal vesicle and epididymes. Antisperm antibodies (ASA) cause sperm agglutination and affect sperm motility, viability and sperm migration in the female reproductive tract. ASA also impair fertilization process. The objective of the present work was to study the effect of prednisolone on sperm motility index (SMI), viability and sperm penetration assay (SPA) in immunologically infertile men.

(2001) Background: infertility is defined as the inability of a couple to conceive after one year of a regular unprotected intercourse with the same partner. Many factors seem to play a role in male infertility.
(2002) Aim: to evaluate the role of some seminal plasma biochemical components in male infertility.
(2003) Methods: seminal plasma of 100 infertile men & 25 fertile men were chosen as a subject of this study.
(2004) Different biochemical parameters that are related to oxidative stress were measured. These included Glutathione Peroxidase (GSHPX),superoxide dismutase (SOD),cerulopasmin (CP) scavenging activity, albumin & total sulfhydral (T-SH) & its individual parts (protein & non protei
Summary:
Background: Alcohol is the most important causes of liver cirrhosis. Many of the factors underlying the development of alcoholic liver diseases remain unknown. Recently, some epidemiological studies showed beneficial effects of coffee against the occurrence of alcoholic liver cirrhosis and upon serum liver enzymes level. These observations have been examined in this work.
Patients and Methods: The relation of coffee drinking to serum GGT, AST and ALT activities were examined in 59 alcoholic male patients with or without habit of coffee consumption. 35 (59.3%) out of 59 patients were alcoholic drinkers without coffee consumption habit, and 24(40.7%) were alcohol drinkers with coffee consumption. In addition to 24 healthy pe

Background: the inferior turbinate is the largest turbinate & it is variable in size due to changes in its submucosal vascular bed.
Aim of study: the aim of the study is the compare between trimming of the inferior turbinate and submucosal diathermy in the same patient a management of turbinate hypertrophy. Subjects <6 Methods : 250cases inferior turbinate hypertrophy diagnosed by direct examination of the nose by anterior& posterior rhinoscopy were collected Aanalyzed in Saddam Medical City during 1995 - 2000 . Clinical examination, X-ray finding, regarding the age, operative procedures, patients follow up, their complications & treatment Results: The place of radical trimming of the inferior turbinate in t

Background: Multiple tumors in the nervous system is a rare event..
Patient & Method: .A forty two years old male who was enjoying completely healthy life presented with one week history of a single attack of confusion .he was presented with double tumour in the brain operated up on our department by craniotomy.
Results: His neurological clinical examination was negative. A CT scan & MRI of the brain showed two intracranial space occupying lesions. A solid right frontal lesion and another cystic lesion in the third ventricle. . The pathology proved the frontal lesion to be a meningioma while the third ventricular tumour was colloid cyst. Post operative period was uneventful. Follow up for few months showed no complaint.

The electrical performance of bottom-gate/top source-drain contact for p-channel organic field-effect transistors (OFETs) using poly(3-hexylthiophene) (P3HT) as an active semiconductor layer with two different gate dielectric materials, Polyvinylpyrrolidone (PVP) and Hafnium oxide (HfO2), is investigated in this work. The output and transfer characteristics were studied for HfO2, PVP and HfO2/PVP as organic gate insulator layer. Both characteristics show a high drain current at the gate dielectric HfO2/PVP equal to -0.0031A and -0.0015A for output and transfer characteristics respectively, this can be attributed to the increasing of the dielectric capacitance. Transcondactance characteristics also studied for the three organic mater

Morphological, structural characteristics and electrical properties were investigated. The state of MWCNTs dispersion in a PVP matrix was indicated by Field Effect-Scanning Electron Microscopy (FESEM) which showed a uniform dispersion of MWCNTs within the PVP matrix. X-ray Diffraction (XRD) indicate strong bonding of carbonyl groups of PVP composite chains with MWCNTs. Fourier transfer infrared (FTIR) studies shows characteristics of various stretching and bending vibration bands, as well as shifts in some band locations and intensity changes in others.

Show MoreThis paper presents the electrical behavior of the top contact/ bottom gate of an organic field-effect transistor (OFET) utilizing Pentacene as a semiconductor layer with two distinctive gate dielectric materials Polyvinylpyrrolidone (PVP) and Zirconium oxide (ZrO2) were chosen. The influence of the monolayer and bilayer gates insulator on OFET performance was investigated. MATLAB software was used to simulate and determine the electrical characteristics of a device. The output and transfer characteristics were studied for ZrO2, PVP and ZrO2/PVP as an organic gate insulator layer. Both characteristics show a high drain current at the gate dielectric ZrO2/PVP equal to -0.0031A and -0.0015A for output and transfer characteristics respectively

Field Effect Scanning Electron Microscope (FESEM) and Fourier Transformer Infrared (FTIR) were used to characterize the surface morphology and optical properties of samples. FESEM images revealed a uniform distribution of graphene within the PVP-MWCNT nanocomposite. The FTIR spectra confirmed the nanocomposite information is successful with apperaring the presence of primary distinct peaks belonging to vibration groups that describe the prepared samples.. Furthermore, found that the DC electrical conductivity of the prepared nanocomposites increases with increasing MWCNT concentratio
