Background: Thyroid nodules commonly occur in the general population. They are often discovered incidentally. Fine needle aspiration biopsy (FNAB) is the usual practice for correctly diagnosing these nodules. Case presentation: The patient was a 24 year female. She presented with a thyroid nodule that was discovered incidentally as an otherwise asymptomatic neck mass. When her husband noticed t...

background: serum lactate dehydrogenase (ldh) concentration is an indicator for tissue injury. it may be secreted locally in many conditions. for the first time, this study was performed to investigate the value of ldh level in bronchoalveolar lavage fluid (balf) in differentiation of benign from malignant single pulmonary nodules (spns) and to assess its relationship with serum ldh levels.   m...

In chest tomosynthesis (TS) the most commonly used reconstruction methods are based on Filtered Back Projection (FBP) algorithms. Due to the limited angular range of x-ray projections, FBP reconstructed data is typically associated with a low spatial resolution in the out-of-plane dimension. Lung nodule measures that depend on depth information such as 3D shape and volume are therefore difficul...

Thyroid hormone biosynthetic defects are rare causes of congenital hypothyroidism. Although, initial presentations are usually diffuse goiter and hypothyroidism, subsequently they may develop thyroid nodules and or thyroid cancer. We describe a case of hypothyroidism due to dyshormonogenesis whose one of the previously solid nodules degenerates into a large cyst. A 22-year-old male was referred...

Agrobacterium-based transformation was used to introduce a promoter-less glucuronidase uidA gene (beta-glucuronidase; GUS) into Lotus japonicus. Transgenic plants were screened for GUS activation at different stages after inoculation with its symbiont, Mesorhizobium loti. Functional GUS fusion frequencies ranged from about 2 to 5% of the total number of transgenic lines. These lines provide exc...

This article has presented a rare case of multiple fibroadenomas of the breasts and axillary accessory breast. In the light of current knowledge, the most proper management is discussed. A 37-year-old woman was referred to our Breast Service due to complaint of a right axillary accessory breast nodule. On physical examination, there were no palpable breast nodules. Bilateral axillary accessory ...

introduction: considering the influence of geographical, genetic and ethnic factors on the prevalence of thyroid pathological lesions, this study was performed to assess the prevalence of pathological lesions in thyroid autopsic samples obtained from adult cadavers of isfahan forensic medical center. material and methods: in this study, 202 thyroid glands from cadavers with no evidence of thyro...

background: fine needle aspiration (fna) has led to a decrease in unnecessary surgeries for thyroid nodules. this study was designed to compare diagnostic value of fna and frozen section methods in the follicular lesions. methods: this is a cross-sectional study based on the medical records of 42 patients who were referred to surgery clinic of rasool-e-akram hospital in tehran with complaint of...

discrimination of regenerative cirrhotic nodules of the liver (cn) from hepatocellular carcinoma (hcc) is sometimes difficult. we examined the utility of agnor staining in this context. fifteen cases of hcc and 25 cases of cn were stained by agnor method and the mean agnor number for one hundred nuclei in each case was determined. there was a significant difference between the mean agnor counts...

S (PH D THESIS) Involvement of auxin distribution in root nodule development of Lotus japonicus (Graduate School of Agriculture, Laboratory of Plant Gene Expression, RISH, Kyoto University) Kojiro TAKANASHI Legumes (Fabaceae) constitute the third largest plant family with around 700 genera and 20,000 species. Legume plants form root nodules through symbiosis with a soil microbe called rhizobia....
