Background: Intramedullary astrocytomas
account for about 1% of all CNS tumors and
6–8% of spinal cord tumors. The vast majority
of intramedullary astrocytomas are slowgrowing
lesions.
Objectives: The goal in this study was to
review a series of patients who underwent
surgical removal of intramedullary high-grade
astrocytomas, focusing on the functional
outcome and the effect of multimodality
treatment on the survival of patients with high
grade intramedullary astrocytoma.
Methods: Between June 1999 and June 2004,
22 patients underwent removal of
intramedullary high-grade astrocytomas in four
neurosurgical hospital in Baghdad/ Iraq
(Neurosurgical hospital, Al Shaheed Adnan
Hospital for Surgical Speeialticsa, Nursing
Home Hospital Lesions were located in the
cervical segment of the spinal cord in 12
patients, and patients.
Results: Histological examinations showed
10 Grade III astrocytomas and 12
glioblastomas. Only 2 of the 22 high-grade
astrocytomas could be completely removed. The
clinical postoperative status worsened in
14 patients (63.6%), was unchanged in seven
patients (31.8%), and there was one case of
intraoperative death (4.5%). None of the 22
patients showed improvement in their
neurological status postoperatively. In this series,
excluding the one intra-operative death, all
patients died of the progression of the
malignancy.
Conclusions: Surgical treatment did not
ameliorate the postoperative neurological status;
instead, in the majority of cases, it prompted a
worsening of the deficit. Radiotherapy and
chemotherapy have a little influence on the
length of survival. In this series, multimodality
treatment of intramedullary high-grade
astrocytomas has been shown to increase length
of survival without improving the neurological
status.
The research aims to shed light on the recent experience in the Iraqi business environment, which is the experience of the merger. To evaluate a recent experience in an important sector of the Iraqi business sectors, namely the industrial sector to enable decision-makers to review that experience to judge the extent of its success and address some of the lapses that experience that by measuring synergies can be judged on the success of the merger experience or not. The research community is the governmental industrial sector. The research sample included six cases of merger (14) companies before the merger. The Holt method was used to predict the net sales and total cost values before the merger as if it were not merged. Th

The researchers used the descriptive approach, as well as used a questionnaire consisting of (20) items distributed into (4) fields. It was administered to a sample of (93) Faculty members. The results of the study showed that the role of the Nizwa University in spreading the concept of knowledge economy among students from the point of view of the faculty members was of a moderate degree. The education and training field came first with the highest average, while the scientific research and innovation field came in the last level. There were no statistically significant d

A field experiment located at the Poultry Research Station, Livestock Department, Agricultural Research Department, Ministry of Agriculture for the period from 16 of September 2018 to 25 of December 2018. One hundred and forty birds of Iraqi local chicken mothers (100 females+ 40 males) at the age of 28 weeks were provided from the poultry research station. The birds were raised in individual cages and distributed sequentially to the cages after the numbering of the females. Data were recorded in three periods, each period was of 28 days, and then the general a
