Quantum dots are new types of fluorescent materials for biological labeling. As a result, QDs toxicity study is an essential requirement for future clinical applications. Therefore, the cytotoxic CdSe:ZnS quantum dots effects on some organs in mice are presented in this study. In this work, 10, 20 and 40 mg/kg doses of CdSe:ZnS quantum dots were injected to 32 adult male mice. Structural and op...

According to Bosniak's classification, renal cysts with moderate calcification, irregular margins, and thickened enhanced septa should raise a suspicion of malignancy. Diagnosis of multilocular renal cysts depends on their histological features. Since 1951, it has generally been considered that a multilocular renal cyst can change from a benign lesion to one which may be combined with malignant...

Histological chorioamnionitis (HCA) is an established marker of ascending infection, a major cause of preterm birth. No studies have characterised the global change in expression of genes involved in the toll-like receptor (TLR) signalling pathways in the presence of HCA in the setting of preterm birth (pHCA). Fetal membranes were collected immediately after delivery and underwent histological ...

tramadol is a synthetic analgesic of opioids which has more flexible mechanisms of action than typical opioids. since it has been reported in previous study that typical opioids like morphine can affect the bone homeostasis, it is worthwhile to examine the effects of tramadol on tooth movement. in this study we investigated effects of tramadol on orthodontic tooth movement in rats.30 male wista...

Ischemia/reperfusion (IR) damage is a major cause of dysfunction in transplanted organs. The objective of the present study was to correlate in vivo measurements of respiratory chain (RC) function with histological and physiological parameters. Non-invasive in situ (surface fluorescence) measurements of mitochondrial NADH and near infrared spectroscopic measurements of cyt aa3 were made in unst...

BACKGROUND The first-line treatment for resectable pancreatic cancer (RPC) is surgical resection. However, our patients have often experienced early recurrence after curative resection for RPC, with desperately poor prognosis. Some reports indicated that minimally distant metastasis not detected at operation might cause early recurrence. The present study aimed to identify preoperative clinicop...

Sarcomatous transformation of the stroma of transplantable mouse carcinomas was first described by Ehrlich and Apolant (5). The following year a case was reported by Loeb (13). Subsequently the phenomenon was observed to occur twice in a strain of mammary carcinoma maintained in these laboratories, and a preliminary note on the subject was published by Bashford, Murray, and Haaland (4). Later a...

Comparison of 3T blood oxygenation level dependent (BOLD) and cerebral blood volume (CBV) activation maps to histological sections enables the spatial discrimination of functional magnetic resonance imaging (fMRI) signal changes into different vascular compartments. We use a standard gradient echo-echo planar imaging technique to measure BOLD signal changes in the somatosensory cortex in respon...
