Hereditary Multiple Exostoses (HME) is a rare pediatric disorder caused by loss-of-function mutations in the genes encoding the heparan sulfate (HS)-synthesizing enzymes EXT1 or EXT2. HME is characterized by formation of cartilaginous outgrowths-called osteochondromas- next to the growth plates of many axial and appendicular skeletal elements. Surprisingly, it is not known whether such tumors also form in endochondral elements of the craniofacial skeleton. Here, we carried out a retrospective analysis of cervical spine MRI and CT scans from 50 consecutive HME patients that included cranial skeletal images...

Inflammation contributes to development and progression in a variety of cancers, including cervical cancer, which is the second leading cause of cancer deaths in women worldwide. In this study, we examined the anti-inflammatory effects of imperatorin, a psoralen-type furanocoumarin from the fruits of Angelica dahurica, in tumor necrosis factor-α (TNF-α)-stimulated HeLa cells by investigating its impact on the production and expression of cytokines and the major signal-transduction pathways. We found this compound significantly inhibited the TNF-α-induced expression of NF-κB target genes, such as COX-2, cyclin  D1, MMP-9, VEGF, IL-6 and Bcl-xL in a concentration-dependent manner...

Sophorolipids (SLs) are glycolipid biosurfactants that have been shown to display anticancer activity. In the present study, we report anti-proliferative studies on purified forms of novel SLs synthesized using cetyl alcohol as the substrate (referred as SLCA) and their anticancer mechanism in human cervical cancer cells. Antiproliferative effect of column purified SLCA fractions (A, B, C, D, E and F) was examined in panel of human cancer cell lines as well as primary cells. Among these fractions, SLCA B and C significantly inhibited the survival of HeLa and HCT 116 cells without affecting the viability of normal human umbilical vein endothelial cells (HUVEC)...

Advanced computational human body models enabling enhanced occupant safety require verification and validation at different levels or scales. Specifically, the motion segments, which are the building blocks of a detailed neck model, must be validated with representative experimental data to have confidence in segment and, ultimately, full neck model response. In this study, we demonstrate the importance of objective validation for quasi-static and dynamic loading. Finite element segment models at all levels in the lower human cervical spine were developed from scans of a 26 year old male subject...

Autologous T cells expressing chimeric antigen receptors (CARs) specific for CD19 have demonstrated remarkable efficacy as therapeutics for B cell malignancies. In the present study, we generated FLAG-tagged CD19-specific CAR-T cells (CD19-FLAG) and compared them to their non-tagged counterparts for their effects on solid and hematological cancer cells in vitro and in vivo. For solid tumors, we used HeLa cervical carcinoma cells engineered to overexpress CD19 (HeLa-CD19), and for hematological cancer we used Raji Burkitt's lymphoma cells, which endogenously express CD19...

RATIONALE: Despite undergoing transforaminal epidural steroid injection (TFESI), many patients complain of persisting cervical radicular pain. For the management of chronic cervical radicular pain, clinicians are widely applying pulsed radiofrequency (PRF) stimulation to dorsal root ganglions (DRGs). To enhance the effect of PRF stimulation, we conducted bipolar PRF stimulation in 2 patients with chronic cervical radicular pain that was refractory to monopolar PRF and repeated TFESIs...

Preventing chronic disease deterioration is an unmet need in people with multiple sclerosis, where axonal loss is considered a key substrate of disability. Clinically, chronic multiple sclerosis often presents as progressive myelopathy. Spinal cord cross-sectional area assessed using MRI predicts increasing disability and has, by inference, been proposed as an indirect index of axonal degeneration. However, the association between cross-sectional area and axonal loss, and their correlation with demyelination, have never been systematically investigated using human post mortem tissue...

Huiying Wang, Jiancong Liang, William H Yong, Peggy Sullivan
BACKGROUND: Pituitary carcinomas are rare neoplasms whose designation requires demonstration of metastatic disease. No specific morphologic features can reliably distinguish pituitary carcinomas from pituitary adenomas, rendering the diagnosis particularly challenging. Furthermore, as reports of pituitary carcinoma on fine needle aspiration (FNA) biopsy are exceedingly rare in the literature, the cytological features of pituitary carcinoma are poorly characterized. CASE REPORT: Here we describe a case of pituitary carcinoma in a 67-year-old woman with history of recurrent adrenocorticotropic hormone (ACTH)-producing pituitary adenoma who presented with a persistent left cervical nodule for 2 years...

We have conducted a 26-month-long comparative study involving young patients (2-6years old) with a clinical diagnosis of spastic equinus secondary to cerebral palsy who have been treated with BoNT/A (BOTOX®, Allergan) tri-annually or annually. Serum samples were obtained to determine the presence or absence of blocking antibodies (Abs) by a mouse protection assay (MPA) and levels of anti-BoNT/A Abs by radioimmune assay (RIA). HLA DQ alleles were typed using blood samples to determine the possible association of certain HLA type(s) with the disease or with the Ab status...

Poor water solubility and adverse side effects pose a challenge for clinical application of paclitaxel (PTX). In this work, a series of PTX dimers are synthesized by coupling two PTX molecules with dicarboxylic acids. As-synthesized PTX dimers form stable nanoparticles in aqueous solution without using any surfactants or adjuvants, and the solubility of PTX in water increases by 2500-fold compared to that of free PTX. These nanoparticles with high content of PTX are internalized by cancer cells and exhibit comparable cytotoxicity with Taxol...

BACKGROUND: Giant cell tumor of bone (GCT) is a rare primary bone tumor, which can metastasize and undergo malignant transformation. The standard treatment of GCT is surgery. In patients with unresectable or metastatic disease, additional therapeutic options are available. These include blocking of the receptor activator of NF-kappa B ligand (RANKL) signaling pathway, which plays a role in the pathogenesis of GCT of bone, via the anti-RANKL monoclonal antibody denosumab. CASE PRESENTATION: Herein we report on a female teenager who presented in a very poor clinical condition (cachexia, diplopia, strabismus, dysphonia with palsy of cranial nerves V, VI, VIII, IX, X, XI and XII) due to progressive disease, after incomplete resection and adjuvant radiotherapy, of a GCT which affected the cervical spine (C1 and C2) as well as the skull base; and who had an impressive clinical response to denosumab therapy...

New treatments based on combinations of standard therapeutic modalities and immunotherapy are of potential use, but require a profound understanding of immune modulatory properties of standard therapies. Here, the impact of standard (chemo)radiotherapy on the immune system of cervical cancer patients was evaluated. Thirty patients with cervical cancer were treated with external beam radiation therapy (EBRT), using conventional three-dimensional or intensity modulated radiation therapy without constraints for bone marrow sparing...
