Carcinoma located in a right-sided sigmoid colon: A case report.

Background: A right-sided sigmoid colon is an extremely rare anatomic variation that should be considered as a possibility by surgeons and radiologists before surgery. Here, we report the first clinical case of a carcinoma in a right-sided sigmoid colon revealed by a preoperative computed tomography (CT).

Case Summary: A 56-year-old Chinese man was admitted to the hospital with abdominal pain.

[CT manifestation for excavated-type of rhomboid fossa of the clavicle].

Objective: To explore the manifestation of CT for excavated-type of rhomboid fossa of the clavicle.

Methods: Nine cases with rhomboid fossaes of the clavicle of 8 patients accepted CT and 1 case added MRI together;all 8 patients were male who aged from 17 to 70 years old with mean age of 42.5 years old;three dimensional reconstruction of all CTs were made, the distance between focus and inside end of clavicle and the size of all focus were measured respectively, then the position, shape, margin of focus were analyzed.

The significance of magnetic resonance imaging in severe femoral trochlear dysplasia assessment.

The clinical diagnosis of femoral trochlear dysplasia primarily relies on imaging. In the past, plain imaging was the major source of diagnosis. The present study investigated the application of magnetic resonance imaging (MRI) in the objective assessment of severe femoral trochlear dysplasia.

The role and the potential regulatory pathways of high expression of forkhead box C1 in promoting tumor growth and metastasis of basal-like breast cancer.

Purpose: To investigate the role of high forkhead box C1 (FOXC1) expression in basal-like breast cancer (BLBC) in vitro and vivo and the underlying regulatory mechanism.

Methods: The lentivirus vector with green fluorescent protein (GFP) was used. MDA-MB-231 cells expressing consistently high levels of FOXC1 (FOXC1-MDA-MB-231) were established.

The effect of superparamagnetic iron oxide with iRGD peptide on the labeling of pancreatic cancer cells in vitro: a preliminary study.

The iRGD peptide loaded with iron oxide nanoparticles for tumor targeting and tissue penetration was developed for targeted tumor therapy and ultrasensitive MR imaging. Binding of iRGD, a tumor homing peptide, is mediated by integrins, which are widely expressed on the surface of cells. Several types of small molecular drugs and nanoparticles can be transfected into cells with the help of iRGD peptide.
