We employ Raman spectroscopy to diagnose benign and malignant lesions in human breast tissue based on chemical composition. In this study, 130 Raman spectra are acquired from ex vivo samples of human breast tissue (normal, fibrocystic change, fibroadenoma, and infiltrating carcinoma) from 58 patients. Data are fit by using a linear combination model in which nine basis spectra represent the mor...

This second phase of the study of "Uptake of Radioactive Phosphorus in Experimental Tumors" deals with the uptake of P32 by malignant tissue, in comparison with that by inflammatory ocular tissue, and an investigation of the influence of vascularity upon the uptake of P32 in normal, inflammatory, and neoplastic tissues. There has been some speculation as to the effect of vascularity upon the up...

The dielectric properties of human liver were determined by characterization of tissue absorption and coupling of electromagnetic energy in the electromagnetic field. In this study the ex-vivo dielectric properties of human hepatocellular carcinoma (well and moderately differentiated), liver hemangioma, hepatic fibrosis (stages S1 and S2), and normal liver tissue were measured and analyzed over...

Two cases of pediatric lung cancer (in 23-month-old and 6-year-old boys) resulting from mother-to-infant transmission uterine cervical tumors were incidentally detected during routine next-generation sequencing paired samples tumor normal tissue. Spontaneous regression some lesions in the first child slow growth mass second suggested existence alloimmune responses against transmitted tumors. Im...

buthotus saulcyi is one of the six most important scorpion species in khuzestan province, which its venom causes probable general effects on its victims. due to insufficient knowledge about mechanism of the venom functions and its target organs and highly dependence of health to normal function of kidney, this survey has been accomplished. in present study, 75 male wistar rats were selected and...

a 21 years old woman presented with a history of sle and skin lesions on the arms, trunk, and abdomen. the left gluteal region was ulcerated and painful and occasionally extruded a chalky white material. the patient referred from rheumatology department for osteomyelitis assessment. on physical examination the patient had hard, nontender lesions on the proximal arms, lower abdomen and lower bac...


 Aim: To characterize and classify stroke lesions normal brain tissue in computed tomography (CT) images using statistical texture descriptors.
 Patients methods: Two experienced radiologists blinded to each other inspected CT of 164 patients identify categorize into ischaemic haemorrhagic subtypes. Four regions interest (ROIs) slice that demonstrated the lesion; two representing les...

BACKGROUND The aim of this study was to investigate whether the anisotropy parameters are helpful in the detection and discrimination of breast cancers, and to determine its value in predicting the risk of cancers. MATERIAL AND METHODS There were 56 patients with 56 lesions (34 malignant, 22 benign) included in the study. DTI was performed in every patient and apparent diffusion coefficient (AD...

Inflammatory injury to the pancreas results in regeneration of normal tissue and formation of metaplastic lesions of a ductal phenotype. These metaplastic ductal lesions (MDL) are called tubular complexes (TC), mucinous metaplasia, or pancreatic intraepithelial neoplasia. Because they are regularly found in chronic pancreatitis and pancreatic cancer, their formation is thought to represent a st...
