Previous studies suggested a relationship between obesity and a high risk of thyroid cancer. However, the association between high body mass index (BMI) and the aggressiveness of papillary thyroid carcinoma (PTC) is controversial. In this study, we aimed to investigate the impact of excess BMI on histopathologic aggressiveness of PTC in a Chinese population.

In the present study, 583 formalin-fixed paraffin embedded (FFPE) thyroid nodule tissues and 161 FNA specimens were enrolled retrospectively. Then BRAF V600E, EZH1 Q571R, SPOP P94R, and ZNF148 mutations among these samples were identified using Sanger sequencing.

The purpose of this study was to assess the value of fine needle aspiration (FNA) cytology in combination with American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) and mutation in differentiating high-risk thyroid nodules.
Methods: From February 2010 to February 2014, 2,643 consecutive thyroid nodules from 2,399 patients (688 men and 1,711 women; mean age, 44.
Background: Clozapine has remarkable efficacy on both negative and cognitive symptoms of schizophrenia due to its slight activation of NMDA receptor. In fact, much evidence to the contrary. NMDAR is a complex containing specific binding sites, which are regulated to improve negative symptoms and cognitive deficits associated with individuals affected by schizophrenia.

Ultrasonographic, cytological, and histopathological diagnoses were retrospectively correlated with K-RAS mutation status in a series of 43 cytologically indeterminate thyroid nodules (CITNs) that were referred for surgical excision. K-RAS mutations were detected in 8/43 (18.

This study evaluated the binding affinity and specificity of the ligands for the NMDA receptor.
Methods: Ligand biodistribution and uptake specificity in the brain were investigated in mice.
The objective of this study was to generate a liver targeting fusion interferon, galactosyl-human serum albumin-interferon alpha2b (G-HSA-IFN) and to evaluate its bioactivity in vitro on HepG2.2.15 cells which express hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg).

Objective: To investigate the effect of betulinic acid (BA) on the proliferation, migration, apoptosis and cell cycle of pancreatic cancer cells (BxPC-3) in vitro and elucidate the underlying.
Method: The effect of BA on the proliferation of BxPC-3 was measured by using sulforhodamine B (SRB) assay. Migratory ability of BxPC3 cells were detected by wound healing assay, and the morphological change was observed with light microscope.

The title mol-ecule, C(13)H(18)N(2)O(3), contains a benzene ring fused to an oxazine ring and one tert-but-oxy-carbonyl group bound to the N atom of the oxazine ring. A weak intra-molecular C-H⋯O inter-action occurs. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds stack the mol-ecules down the b axis.

Molecular imaging is a promising method estimating the expression of specific molecules in vivo, and the goal of this study was to evaluate a radioiodinated anti-epidermal growth factor receptor (EGFR) human Fab as a molecular imaging agent for diagnosis.
Materials And Methods: Three human tumor cell lines representing tumors with different levels of EGFR expression were selected and their corresponding xenografts produced.
The antiviral activity and biodistribution of a glycosylated fusion interferon directed to hepatic receptors were evaluated to determine whether its pharmaceutical concentration in the liver could be improved. The novel glycosylated fusion interferon, galactosyl-human serum albumin-interferon-alpha2b (G-HSA-IFN) was obtained from a long-term recombinant fusion protein (HSA-IFN) by covalent coupling with a bifunctional reagent, 2-imino-2-ethyloxymethy1-1-thiogalactose. There are about 24 thiogalactose residues in each G-HSA-IFN molecular on average.

Three different strategies for increasing RADD production were examined: to select the suitable host strain, to optimize the rare codons, and to delete the amino acids residues. The total fusion protein glutathione-S-transferase (GST)-RADD concentration of 298 mg/l and 326 mg/l were achieved by selecting E.

Aim: To study the inhibitory effect of 23-HBA on angiogenesis in vitro.
Methods: The effect of 23-hydroxy butulinic acid (23-HBA) on the in vitro proliferation of human microcapillary endothelial cells(HMECs) was examined by sulfonylrhodamine B (SRB) assay. The effect of 23-HBA on endothelial cell migration, and tubule formation on Matrigel was also observed.
