Automated differentiation of benign and malignant liver tumors by Ultrasound Images

Background & Aims: Early detection and reliable differentiation of benign and malignant liver tumors could lead to improved cure rate and costs. Ultrasound image (US) is a convenient medical imaging method for interpreting liver tumors. Visual inspection of ultrasound images sometimes is combined with error and needs biopsy to confirm whether a tumor would be benign or malignant. The aim of thi...

Computerize classification of Benign and malignant thyroid nodules by ultrasound imaging

Introduction: Early detection and treatment of thyroid nodules increase the cure rate and provide optimal treatment. Ultrasound is the chosen imaging technique for assessment of thyroid nodules. Confirmation of the diagnosis usually demands repeated fine needle aspiration biopsy (FNAB). So, current management, has morbidity and non zero mortality. The goal of the present study ...

Comparison of the effect of quasitrapezoidal and rectangular pulses on bio- electrical activity, calcium spike properties and afterhyperpolarization potentials of Fl cells of Helix aspersa using intracellular recording

  While the effect of changes of stimulus waveform (quasitrapezoidal and rectangular current pulses) on nerve activation is clear, but there is no evidence on the effect of quasitrapezoidal pulses on ionic currents of cellular membrane. In the present study, the effect of depolarizing quasi-trapezoidal current pulses, in comparison with that of depolarizing rectangular current pulses, on firing...

Activation-Induced Apoptosis in T cells: Effect of Age and Caloric Restriction

We have previously shown that the proliferative response of T cells to antigenic or mitogenic stimulus decreased with age and that caloric resection (CR) attenuated the age-related decline in proliferation and IL-2 expression. Because activation-induced apoptosis is known to regulate cell proliferation and eliminate the high number of activated cells during an immune response, it was of interes...
