Abstract

The objective of the present work was to investigate the anatomical andhistological structures of haemolymph nodes in the adult water deer (Hydropotesinermis argyropus). Methodology: the morphology of haemolymph nodes from 5adult water deer was studied by gross inspection and by histological methods.Results: the haemolymph nodes were determined for the first time in water deer(Hydropotes inermis argyropus). The nodes located in the neck on the trachea,thoracic and abdominal cavities in water deer. Dark red in color and oval- or roundshaped haemolymph nodes in water deer were observed particularly along theabdominal aorta and caudal vena cava; as well as on the trachea along the jugularvein, on the internal carotid artery and internal jugular vein and on the aortic arch.These nodes had a hilus with hilar vessels, which entered the haemolymph nodesthrough the trabeculae as trabecular artery. The parenchyma was organized in theform of cortex and medulla. Lymphoid rim was located between subcapsular sinusand cortex. The cortex was composed of a many secondary lymphoid follicles anddiffuses interfollicular lymphoid tissue, and medulla contained medullary cords andmedullary sinuses. A reticular meshwork extended throughout the haemolymphnodes formed the structure backbone. The interstices of the reticular meshwork werefilled with free blood cells, many macrophages, lymphocytes, and plasma cells.Conclusion: the dark red haemolymph nodes of water deer examined were seenalong the course of large blood vessels in the neck on the trachea, thoracic andabdominal cavities. This is first study has demonstrated the presence of haemolymph nodes in water deer (Hydropotes inermis argyropus) and provided essentialinformation on their anatomical and histological structures. The data obtained in thepresent study may be used for further research in this field

Abstract

Abstract It is previously reported that cancer prognosis is affected by mutations of P53 gene. However, the prognostic significance of P53 mutated gene detection in breast cancer is a subject demanding numerous investigations in a view of numerous facts such as presence of different tumor subtypes, P53 positivity in early breast cancer, different overall survival and disease free period as well as variability of tumor response to chemotherapeutic agents and presence of primary resistance of tumor among patients whether same or different grade and stage. Hence, it is of interest to detect this mutated gene in our area and evaluate its relation to other prognostic factors in terms of age, stage, histological grade and lymph node status. This study aimed to evaluate the relation of P53 mutated gene expression in female with breast cancer in respect to the other prognostic factors such as age, grade, stage and lymph node status. Fifty female patients diagnosed as a breast cancer, underwent clinical and pathological staging (I,IIA,IIB,IIIA,IIIB,IIIC, and IV), histopathological grading (I,II,III). All patients underwent same surgical operation which was modified radical mastectomy and axillary dissection. All specimens were sent to histopathological study and P53 mutated gene detection study by using immunohistochemistry (IHC). P53 mutated gene was detected by immunohistochemistry in 72% of patients with breast cancer. P53 positivity showed a statistically significant direct proportion to histological grade, stage and lymph node status. In addition, more P53 mutated gene expression was detected in younger patients (age group ≤49 years old) and this probably explaining more advance stage observed in this group in this study. All these data leads to a conclusion that the presence of mutated p53 gene is associated with worse prognosis. This study detected P53 mutated gene by IHC for the first time in our region and showed a statically significant association between status of P53 gene mutations and the other prognostic factors such as age, histological grade, stage and lymph node status and consequently to tumor aggressiveness and thereafter to prognosis.

Abstract

ABSTRACT:BACKGROUND:Elastography is a promising diagnostic tool that is increasingly used by radiologists to increase the sensitivity and specificity of conventional ultrasound in a wide range of disease processes. One of its major uses was to differentiate between benign and malignant lesions.OBJECTIVE:Is to investigate the value of elastography in assessing lymph nodes in the patients with breast carcinoma.PATIENTS AND METHODS:This single center prospective cross sectional study involved forty-nine (49) women with breast cancer and the total of sixty (60) lymph nodes (LNs) that were suspicions to be metastatic. The study was carried out at Al-Imamain Al- Kadhimain Medical city/the breast clinic, from January 2016 through October 2016. Ultrasound examination included conventional B-mode, power Doppler and elastography at same session. The results were compared with tissue diagnosis of biopsy specimens and fine needle aspiration cytology.RESULT:Our final result included 60 LNs, 33 reactive and 27 metastatic. The Mean of B-mode score of lymph nodes involved by metastasis was higher than that of reactive lymph nodes, 3.26 ±0.98 versus 1.00 ±1.12, and the difference was highly significant (P<0.001). While the mean for strain elasticity score of lymph nodes involved by metastasis was higher than that of reactive lymph nodes, 3.89 ±0.70 versus 1.85 ±0.76, and the difference was highly significant (P<0.001). The Mean strain ratio of lymph nodes involved by metastasis was higher than that of reactive lymph nodes, 5.04 ±1.96 versus 1.7 ±0.87, and the difference was highly significant (P<0.001). Overall sensitivity and specificity of B mode US was 81.5% and 90.9% respectively, sonographic elastography sensitivity and specificity 77.8% and 100.0% respectively, while the sensitivity of combined B mode and elastographic ultrasonography increase to 96.3%.CONCLUSION:The present study showed that combined ultrasound B-mode and elastography added significantly to the sensitivity of ultrasound differentiation among benign lymph nodes and those which are involved by malignant metastasis.

Abstract

AIMS: This study was conducted to see whether the hilar echogenicity alone is a good criteria for detection of cervical lymph node metastasis in patients with oral squamous cell carcinoma(OSCC). MATERIALS AND METHODS: Twenty patients with OSCC ( 14 males and 6 females) , their age 40- 90 years , were examined sonographically, and the number of cervical lymph nodes studied was 112. Hilar echogenicity alone was used as a criteria to differentiate between benign and malignant cervical lymph nodes. Lymph nodes were evaluated for their echogenic hilus, number, size, site, shape , as well as for necrosis. The results of US evaluation were compared with histopathologic outcome using unpaired t-test and Fisher’s exact probability test. RESULTS: Ultrasound examination yielded a sensitivity as 84.09%, specificity 95.59%, accuracy 91.07%, positive predictive value (PPV) 92.5% , and negative predictive value (NPV) 90.28%. CONCLUSIONS. Sonographic examination have a high accuracy in detecting cervical lymph node metastasis in patients with oral squamous cell carcinoma, depending on hilar echogenicity as a diagnostic criteria .

Abstract

Abstract:In several cases, it is important, or even necessary, for a device in the wireless sensor network to beaware of its location in the network. For example, the event detection process loses its importance ifthe wireless sensor network cannot provide any information about where the event occurred.However, site information cannot be manually configured on each device during deployment. It isalso futile to place the future of the Global Positioning System (GPS) at each node, due to physicaland publishing limitations (e.g. GPS does not work within the structure) and other limitations relatedto the power of the device. In this paper we proposed new methodologytodetermine the location ofnodes by using Genetic Algorithms(GA).GA consider an important technique in the search for thebest choice of a set of solutions available for a particular design. Through the results obtained usingthe proposed algorithm, this method can be considered more reliable and cost effective thantraditional methods.

Abstract

THE EFFECT OF LIMITED VERSUS EXTENDED AXILLARY LYMPH NODES DISSECTION IN THE DEVELOPMENT OF POST-MASTECTOMY MORBIDITY Ahmed N Abdulnabi MB,ChB, CABS, Specialist of General Surgery, AL-Fayhaa Teaching Hospital, Basrah, IRAQ. Abstract Breast cancer is a common malignancy in female, modified radical mastectomy is widely used for the management of this tumour. Axillary lymph nodes dissection is accompanied by frequent postoperative morbidity including wound infection, paresthesia, seroma and upper limb lymphedema. This is a comparative study that was conducted to evaluate the frequency of postoperative morbidity in a limited and extended axillary lymph nodes dissection. One hundred and fifty patients were treated by modified radical mastectomy for invasive ductal carcinoma of the breast between January 2008 and October 2015 in Al-Fayhaa Teaching Hospital. This sample was divided into two groups; the first fifty patients were managed with limited N1 axillary dissection while the other one hundred patients with extended N2 axillary dissection. The postoperative morbidity in the form of wound infection, paresthesia, seroma formation and upper limb lymphedema were analyzed in respect to the N1 or N2 axillary lymph nodes dissection. The highest occurrence was in the age group between 36 and 45 years. Wound infection develops in 16% of patients in the first group and 12% in the second group. Seroma occurred in 20% in the first group and 23% in the second group. Paresthesia was obviously higher in the second group (19%) when compared with 4% in the first group. Lymphedema occurred more in the second group (26%), and less in the first group (4%). In conclusion, limited axillary lymph nodes dissection during modified radical mastectomy for patients with no or few axillary lymph nodes involvement is associated with low postoperative morbidity.

Abstract

Wireless networked control systems (WNCS) are considered one of the main attracting topics in the control, communication and computing domains. One of the main problems that face these systems is the various time delays which occur in the measurements. The control design process would be complicated if there is a time delay in the feedback loop. Moreover, this delay affects the system performance in terms of instability. The literature of WNCS shows that the available controllers can deal with a limited number of nodes. Beyond this limit, the system becomes unstable. In this paper, an optimized Particle Swarm Optimization (PSO)-based PID and FOPID controllers are proposed for WNCS to control the plant wirelessly. The proposed controllers aim at minimizing the time delays and can make the system remains stable when the network tackles a large number of nodes with variable length packet sizes. The performances of the proposed optimized controllers are compared to show which one of them can be more robust against the challenges of WNCS, namely varying time-delays, to handle a greater number of nodes. The results show that the FOPID is more powerful than the PID controller.

Abstract

The rate of uniform convergence for Hermite-Fejer polynomials to any continuous function f(x) in each closed sub-interval of (-1,1) has been given by Schonhage in 1971 by means of estimating the rate of convergence. The present paper deals with the acceleration of convergence and the rate of convergence by improving the estimate given by Schonhage, throughout two parallel ways, firstly, by use of the averaged moduli of smoothness or -moduli that gives much better estimation than that of the moduli of continuity or -moduli. Secondly, by make use of the necessary and sufficient conditions that we borrow from Szego in 1959 together with the well-known Fejer's identity (3.8) and the properties of -moduli in addition to some known results that have been given by Murray Spiegel in 1981 pp299-345.
