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...
Goiter (diffused or focal enlargement of thyroid), is one of the most frequent complaints referred to endocrinologists. Goiter is evaluated for thyroid function & anatomical from of the gland. Understanding distribution of patients among different groups, & their signs & symptoms will help to choose a better diagnostic & therapeutic approach. Possible differences of patients characteristics in ...
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 ...
BACKGROUND Non-thyroidal illness (NTI) refers to changes in thyroid hormone levels in critically ill patients in the absence of primary hypothalamic-pituitary-thyroid dysfunction, and these abnormalities usually resolve after clinical recovery. However, NTI can be accompanied by primary thyroid dysfunction. We report herein a case of a woman with NTI accompanied by primary hyperthyroidism. CA...
Leguminous biological nitrogen fixation (BNF) is very sensitive to environmental fluctuations. It is still contentious how BNF is regulated under stress conditions. The local or systemic control of BNF and the role played by reactive oxygen species (ROS) in such regulation have still not been elucidated completely. Cadmium, which belongs to the so-called heavy metals, is one of the most toxic s...
Medicago truncatula belongs to the legume family and forms symbiotic associations with nitrogen fixing bacteria, the rhizobia. During these interactions, the plants develop root nodules in which bacteria invade the plant cells and fix nitrogen for the benefit of the plant. Despite massive infection, legume nodules do not develop visible defence reactions, suggesting a special immune status of t...
A 52-year-old woman presented with a small midline anterior neck mass and a 3-kg-weight loss over the course of one month. The patient was diagnosed with Graves disease based on increased free T4 levels (3.30 ng/dL), suppressed thyroid stimulating hormone (TSH) levels (<0.001 IU/mL), and a high titer of TSH receptor antibodies (32.6 IU/L). Scintigraphy with Tc-99m pertechnetate (Fig. 1) also re...
The presence of hyperthyroidism is no longer an insurance against the occurrence of thyroid cancer. The combination of the two is common. This is a retrospective study of 355 files of patients followed for differentiated thyroid cancer in the endocrinology department at CHU IBN ROCHD from 1986 to 2014. 12 of those patients were followed for hyperthyroidism, and a fortuitous association with dif...
Percutaneous ethanol injection (PEI) is a technique used only for benign thyroid nodules, cystic or mixed cystic-solid with a large fluid component. It is a quite low-cost, safe, and outpatient method of treatment. Rare and severe complications have been described after PEI: jugular vein thrombosis and severe ethanol toxic necrosis of the larynx combined with necrotic dermatitis. Moreover, only...
