A 48-year-old black woman presented to the University Hospital Medical Center in 1978 with skin lesions. A chest radiograph obtained in 1970 was essentially normal. In March of 1978, she developed small nodules in both lungs and fullness in both hila. Bed rest and various creams for the skin lesions were prescribed. In November of 1978 she developed diffuse bilateral infiltrates and hilar adeno...
Five cases of extensive infarction of lymph nodes were traced in just over 16 years' surgical material. All presented with painful swelling in a superficial lymph node chain. None was diagnosed clinically; two were interpreted as fibroadenoma of the axillary tail of the breast, and two as a femoral hernia. Microscopically the lymph nodes in the first three weeks after infarction were characteri...
Although there have been great advances in our understanding of the bacterial cytoskeleton, major gaps remain in our knowledge of its importance to virulence. In this study we have explored the contribution of the bacterial cytoskeleton to the ability of Salmonella to express and assemble virulence factors and cause disease. The bacterial actin-like protein MreB polymerises into helical filamen...
The automated segmentation of lymph nodes (LNs) in ultrasound images is challenging, largely because speckle noise and echogenic hila. This paper proposes a fully automatic accurate method for LN that overcomes these issues. proposed integrates diffusion-based despeckling, U-Net convolutional neural networks morphological operations. First, the suppressed node edges are enhanced using Gabor-bas...
Isoniazid, is the only antituberculous drug for which the relation between lack of virulence and acquisition of resistance was associated. INH-resistant mutants were shown to contain defective katG gene. Classical studies showed that INH-resistant south Indian isolates have lower virulence in guinea pigs and higher susceptibility to H2O2. It is of interest to assess the virulence in south India...
Background and Objective: Janus kinase 2 (JAK2) and Myeloproliferative Leukemia (MPL) mutations are confirmatory indicators for Myeloproliferative Neoplasm (MPN). The current study was performed to determine the frequency of MPL mutation in MPN patients without JAK2 mutation, in order to assign MPL mutation frequency in North-East of Iran.Methods: Total o...
