Primary thyroid gland lymphomas (PTLs) typically occur in middle-to older-aged individuals in the setting of lymphocytic thyroiditis with a predilection for females. Diffuse large B-cell lymphoma is the most frequent histologic subtype of thyroid lymphomas. Small lymphocytic lymphoma (SLL) belongs to the least common subtypes of thyroid lymphoma. It is often associated with the involvement of l...
Indolent breast lymphomas (IBL) are a rare form of extranodal lymphoma. There are very few reported cases of IBL presenting as a breast mass. We report two cases of IBL, a Marginal Zone Lymphoma (MZL) and a Small Lymphocytic Lymphoma (SLL), which were discovered on routine mammogram and later confirmed by biopsy and flow cytometery. Patient with MZL underwent chemotherapy and radiation therapy ...
The components of commercial sodium stearoyl lactylate (SSL), purchased in Japan, were determined and identified using thin layer chromatography (TLC) and liquid chromatography with mass spectroscopy (LC-MS). Stearoyl lactate (SL) and stearoyl-2-lactylate (SLL) were purified using TLC and silica gel chromatography to obtain standards. The results show that SSL consisted of lactic acid (8.4%), s...
Simultaneous involvement of the anterior mediastinum by thymoma and B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), to our knowledge, has not been previously reported. We describe a composite tumor composed of thymoma and CLL/SLL incidentally discovered in a 62-year-old man who had no history of malignant diseases or immunologic disorders. The preoperative peripheral b...
A design problem of non-uniform circular antenna arrays for maximum reduction of both the side lobe level (SLL) and first null beam width (FNBW) is dealt with. This problem is modeled as a simple optimization problem. The method of Firefly algorithm (FFA) is used to determine an optimal set of current excitation weights and antenna inter-element separations that provide radiation pattern with m...
In this paper, optimal designs of three-ring concentric circular array antennas (CCAA) without and with central element feeding are reported. For each design set, optimal current excitations and radii are determined with the objective of maximum Sidelobe Level (SLL) reduction. The optimization technique adopted is Novel Particle Swarm Optimization (NPSO). To enhance the optimization performance...
Abstract This paper presents a study on the side-lobe level (SLL) reduction with transmission type metasurface (MTS) using concept of non-uniform array technique and transmit antenna. According to antenna technique, SLL can be controlled by controlling amplitude phase distribution simultaneously. Initially, is used design MTS. The radiation characteristics MTS are analyzed exciting rectangular ...
Objectives: Diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) depends on specific immunophenotype of select antigens and their characteristic density. However, reports detailing how the expression of specific antigen changes over time of disease course are sparse. Methods: We identified 37 CLL/SLL with initial and follow-up samples studied by flow cytometry. Express...
Non-germinal center small B-cell lymphomas represent a heterogeneous group of non-Hodgkin lymphomas, the most frequent histologic subtypes being small lymphocytic lymphoma (SLL), splenic marginal zone B-cell lymphoma (MZL), and mantle cell lymphoma (MCL). In order to identify genomic signatures specific for each disease, we analyzed 128 primary tumors using high-density microarrays. Several clu...
We establish the following specific relation between contextfree grammars that have LL(k) and LR(k) parsers, respectively: after cleaning an SLL(1) grammar (by unfolding its empty productions), the resulting grammar is SLR(1).
