Objective: The aim of this study was to determine the pattern of hematological malignancies at Al-Gamhouria Teaching Hospital from 2008 to 2010.Material and Methods: Hematological malignancies diagnosed at Al-Gamhouria Teaching Hospital, Department of Hematology-Oncology from January 2008 to December 2010 based on available hematological laboratory methods and histological examination were retrospectively analyzed. Clinical diagnoses were based on history and physical examination. Complete blood count was performed in all patients, bone marrow aspiration was performed in leukemia and multiple myeloma patients, and histopathological examination was performed in cases of malignant lymphoma.Results: Malignant hematological disorders were diagnosed in 300 patients aged 18-80 years (mean age: 43.6 years) with a male:female ratio of 1.23:1. Among the male patients the most common malignant disorder was non-Hodgkin's lymphoma, followed by Hodgkin's lymphoma and acute myeloid leukemia. Among the female patients the most common malignant disorder was non-Hodgkin's lymphoma, followed by acute myeloid leukemia, and Hodgkin's lymphoma. The study provides the frequencies for the main hematological disorders and present the different subtypes of the Hodgkin's and non-Hodgkin's lymphomas.
Conclusion:The most common hematological malignancies in male patients were Non-Hodgkin's lymphomas followed by Hodgkin's lymphoma and acute myeloid leukemia. Gender distribution showed male predominance with striking predominance in Hodgkin's lymphomas (M:F Ratio of 1.9:1).
Many pathologic disease can be considered as related to an Endogenous toxicological moves and in time dependent way (kinetics and dynamic of the process). In this work starting from the analysis of relevant literature involved with different disease and related to the endogenous local micro-environment some global conclusion useful as new tools for innovative pharmacological strategies will be submitted to the researcher. Physiology, pathology concept linked to the endogenous toxicological local microenvironment status as new research instruments. The same carcinogenesis process can be related also to endogenous agents that may have a major contribution in spontaneously process. (Reactive oxygen species (ROS), which are involved in multiple cellular processes by physiologically transporting signal as a second messenger or pathologically oxidizing DNA, lipids, and proteins).
In this paper, a new soft‐fusion approach for multiple‐receiver wireless communication systems is proposed. In the proposed approach, each individual receiver provides the central receiver with a confidence level rather than a binary decision. The confidence levels associated with the local receiver are modeled by means of soft‐membership functions. The proposed approach can be applied to wireless digital communication systems, such as amplitude shift keying, frequency shift keying, phase shift keying, multi‐carrier code division multiple access, and multiple inputs multiple outputs sensor networks. The performance of the proposed approach is evaluated and compared to the performance of the optimal diversity, majority voting, optimal partial decision, and selection diversity in case of binary noncoherent frequency shift keying on a Rayleigh faded additive white Gaussian noise channel. It is shown that the proposed approach achieves considerable performance improvement over optimal partial decision, majority voting, and selection diversity. It is also shown that the proposed approach achieves a performance comparable to the optimal diversity scheme.
Cancer is recognized nowadays as one of the important diseases in Yemen from the public health view. During the last three decades, remarkable changes in oncology health care services were observed in the country, mostly in urban areas. According to the Global Cancer Observatory of the International Agency for Research on Cancer, the total cases reported in the year 2020 was 16,476 new cases, and the top five reported cancers in the country were: breast cancer, colorectum, leukemia, stomach, and non-Hodgkin lymphomas. This rank of cancer types is probably unlike what exists in the neighboring Gulf countries. Oncology services in the country suffer from very limited radiotherapy care, chemotherapy centers, as well as many essential diagnostic laboratories for cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
