Preneoplastic mammary nodule outgrowth lines were examined for their ability to grow and produce tumors in ovariectomized BALB/c mice. In addition, these nodule outgrowth lines and tumors derived from them were investigated for cytoplasmic estrogen receptor proteins by qualitative and quantitative techniques. Early ovariectomy, performed within 4 weeks after transplantation, slightly delayed bu...

Background: Clinically solitary thyroid nodule may be defined as a goitre which on clinical examination appears to be a single nodule in an otherwise normal gland. In reality, solitary thyroid nodule is not a single disease process but a constellation of processes encountered in a variety of clinical diseases such as dominant nodule of a multi nodular goitre, true adenoma, malignancy, thyroidit...

Detection of malignant lung nodules in chest radiographs is currently performed by pulmonary radiologists, potentially with the aid of CAD systems. Recent advancements in convolutional neural network (CNN) models have improved image classification and detection for many tasks, but there has been little exploration of their use for nodule detection in chest radiographs. In this paper we explore ...

umbilical cord blood (ucb) as a source of hematopoietic stem/progenitor cells (hspcs) used for umbilical cord blood transplantation (ucbt). the main obstacle in application of this source as an appropriate source of hspcs is low volume of this product. so ex vivo expansion of these cells in a microenvironment which mimic body condition is important. in current study we designed biocompatible mi...

background the aim of this study was the ex vivo expansion of umbilical cord blood hematopoietic stem cells on biocompatible nanofiber scaffolds. materials and methods cd133+ hematopoietic stem cells were separated from umbilical cord blood using midimacs (positive selection) system by means of monocolonal antibody cd133 (microbeads) subsequently, flowcytometry method was done to assess the pur...

background: leptin is a protein product of obesity gene and is synthesized mainly by adipose tissue. objective: the aim of this study was to determine maternal and neonatal serum leptin levels in term preeclamptic and normal pregnancies. materials and methods: this cross sectional study was performed on 37 preeclamptic and 40 normotensive term pregnant women without other disease. serum level o...

prevalence of thyroid nodules diagnosed by ultrasonography has been reported to be high (about 50%) probably due to iodine deficiency in our region. most thyroid nodules benign but some require treatment for cosmetic reasons or subjective symptoms. the conventional method of treatment in iran is surgery. for the first time in iran, from february 2016, 50 patients with 63 nodules (solid or cysti...

background:speech is the most important communication tool and is the smooth product of four systems: respiratory, phonatory, resonatory, and articulatory. currently, a variety of voice disorder occurred because of life style and environmental pollutants. vocal nodule is one of the most prevalent disorders in this category. considering the point that the air required for vocal cords vibration i...
