The morphological description and histological structure of Kidney in barn owl Tyto alba have been invesigated. The results of present study revealed that barn owl has pair of elongated solid kidney situated symmetrically on both sides of vertebral column. Each kidney consists of three lobes represented by carnial, middle and caudal lobes and all of then covered by a capsule of connective tissue. Microscopical examination showed that the basic unit of kidney in barn owl represented by lobules which have conical shaped and each of them consists of cortex and medulla, and the cortex occupies more area than that of medulla. The results of the present study revealed that the glomerulus in barn owl represented by relatively small spherical structure and each glomerulus has vascular and urinary poles , and the glomeruli distributed randomly within the cortex tissue of the kidney. Each glomerulus coverd by capsule called Bowman's capsule. The results of the present study showed that the tubules represented by proximal convoluted tubules, distal convoluted tubules, loops of Henle in addition to the collecting tubules which lead to collecting ducts. All tubules lined by simple epithelial tissue ranged from low cuboidal in thin segment of Henle loop to cuboidal in other parts. It in important to note that the free surface of the cuboidal cells have brush border in proximal convoluted tubules. The collecting ducts lined by simple columnar epithelium. The histological examination revealed that the wall of ureter consists of internal layer of ciliated pseudostratified columnar epithelium then smooth muscle layer and the outer-most layer represented by the adventitia of loose connective tissue.
Urban morphological approach (concepts and practices) plays a significant role in forming our cities not only in terms of theoretical perspective but also in how to practice and experience the urban form structures over time. Urban morphology has been focused on studying the processes of formation and transformation of urban form based on its historical development. The main purpose of this study is to explore and describe the existing literature of this approach and thus aiming to summarize the most important studies that put into understanding the city form. In this regard, there were three schools of urban morphological studies, namely: the British, the Italian, and the French School. A reflective comparison between t

Show MoreSome microorganisms can produce nanocellulose, which is known as bacterial nanocellulose (BNC); the most active bacterial producer is acetic acid bacteria (AAB), which is a gram-negative, motile and obligate aerobic belongs to the family Acetobacteraceae. Bacterial nanocellulose has excellent attention in medical (surgical domain), industrial and pharmaceutical fields because of its flexible properties, characteristics and advantages. So, in this study, the AAB (5AC) isolate was isolated from apple vinegar. The production of BNC was performed by using a natural medium called palm dates liquid medium, the produced bacterial Cellulose was purified by using the sodium hydroxide method; it was observed that the wet weight of the BNC was a

Thirty pregnant rats were enrolled, which were divided into two groups A control (10), B treated (20). Group (A) were given distilled water orally for 15 days of pregnancy period. The other group was subdivided into two subgroups B1, B2 (each with 10 rats), which were treated with LEV for 14 days for subgroup (B1) and 15 days for the other subgroup (B2). The drug (350 mg/kg/day) is administered orally. Based on our results there was damage in the kidney due to the toxicity of the drug. The histopathological effects is represented

This paper presents a morphological and anatomical study of the leaves and stems of Asphodelus microcarpus. The results showed that the investigated species had typical morphological characters. and also that it could be distinguished from another plant not only by its morphological but anatomical characters as well.
Hartha Formation is an overburdened horizon in the X-oilfield which generates a lot of Non-Productive Time (NPT) associated with drilling mud losses. This study has been conducted to investigate the loss events in this formation as well as to provide geological interpretations based on datasets from nine wells in this field of interest. The interpretation was based on different analyses including wireline logs, cuttings descriptions, image logs, and analog data. Seismic and coherency data were also used to formulate the geological interpretations and calibrate that with the loss events of the Hartha Fm.
The results revealed that the upper part of the Hartha Fm. was identified as an interval capable of creating potentia

Show MoreThis research sheds light on the morphological construction of kitchen terms in Hebrew language, especially methods of derivation, by offering an extensive review of the most important methods of morphological derivation. The field of kitchen terms is a fertile and rich field, where we see daily production of new kitchen tools which require suitable names with specific meanings. Morphologically, the research interested in methods of morphological derivation. So as to know and identify the common and effective methods to derive the kitchen terms in Hebrew language, in addition to put a special glossary of these terms. The research found that most of the kitchen terms were derived according to the methods of derivation prevailing in Hebrew la

It becomes very important to detect the tumor and classify it at the early stage so that appropriate treatment can be planned. Accurate estimation of kidney tumor volume is essential for clinical diagnoses and therapeutic decisions related to renal diseases. The main objective of this research is to use the Computer-Aided Diagnosis (CAD) algorithms to help the early detection of kidney tumors that addresses the challenges of accurate kidney tumor volume estimation caused by extensive variations in kidney shape, size and orientation across subjects.
In this paper, have tried to implement an automated segmentati
Levetiracetam (LEV) is new antiepileptic drugs (AEDs), usually used with other drugs in case of inadequate control of seizures. It is usually discharge with the breast milk. This study was conducted for the evaluation of the effect of levetiracetam on the kidney after 3 and 7 day newborn albino rats (Rattus rattus). A total of 20 rats were taken which were divided into two groups (A/control and B/ treated). The rat pregnant group (A) represents control group which has given distilled water orally during the pregnancy period and continued in taking of till one week newborn and (B) represents treated groups the drug was administered (350 mg/kg/day) orally during the pregnancy period and continued in taking of drug till one week newborn.

The role of MTX in the treatment of RA has now been well established. The use of MTX treatment of RA inhibits proliferation of the lymphocytes, reduces signs and symptoms this disease, reduces progression damage of the joints and improves quality of life outcome. Progranulin (PGRN) acts a role in autoimmune inflammatory, has important function in several processes including immune response. Present study has conducted to find the effect of MTX drugs as a therapeutic target for RA patients because of its ability to bind with tumor necrosis factor receptor (TNFR), with progranulin, obestatin an

The classification of Salix at the generic and infra-generic levels is still outstanding. We have agreed to list the Egyptian species of this genus. We collected them during field trips to most Egyptian habitats; fresh and herbarium specimens were subjected to taxonomic revision based on morphological characters; scanning electron microscope (SEM) for pollen grains; isozyme analysis using esterase and peroxidase enzymes and genetic diversity using random amplified polymorphic DNA (RAPD). We recorded that both sexes of S.
