The aim of the present study was to evaluate the in vitro effect of a heat shock protein (Hsp)90 inhibitor, SY-016, on the paclitaxel (PTX)-resistant human ovarian cancer cell line OVCAR-3PTX, and explore its mechanism of apoptosis. In the present study, SY-016 was used in combination with PTX to determine its effect on the cell proliferation and apoptosis of OVCAR-3PTX cells. The drug-resistant tumor cells were established in vitro by stepwise sequential exposure to increasing concentrations of PTX. The cell viability and cell cycle distribution were measured by MTT assay and flow cytometric analysis, respectively...

Sphingosine kinase 1 (Sphk1) is an oncogenic kinase that is responsible for the phosphorylation of sphingosine to sphingosine-1-phosphate (S1P). Mounting evidence suggests that Sphk1 serves a crucial role in the proliferation and development of a variety of human cancer cells. However, the role of Sphk1 in hepatocellular carcinoma (HCC) has not been fully elucidated. Therefore, the expression of Sphk1 was examined in 127 formalin-fixed, paraffin-embedded HCC tissues using immunohistochemistry, and its clinical implications and prognostic significance were analyzed...

The balance between the production and elimination of reactive oxygen species (ROS) is essential in determining whether cells survive or undergo apoptosis. Nuclear factor erythroid 2-related factor 2 (Nrf2) may act as a sensor for electrophilic stress, thus regulating the intracellular antioxidant response. The present study investigated the role of vitamin C (VC) and quercetin (Q) in the induction of Nrf2-mediated oxidative stress in cancer cells. An MTT assay was conducted to examine the anti-proliferative effects of VC and Q...

Human aspartyl-(asparaginyl)-β-hydroxylase (HAAH) has recently been the subject of several studies, as it was previously observed to be overexpressed in numerous types of carcinoma cells and tissues in patient tumor samples. HAAH has been implicated in tumor invasion and metastasis, indicating that it may be an important target and biomarker for tumor diagnosis and treatment. However, the immunological tools currently available for the study of this protein, including monoclonal antibodies, are limited, as is the present knowledge regarding the role of HAAH in tumor therapy and diagnosis...

Immunotherapy with dendritic cells (DCs) is a great promise for the treatment of neoplasms. However, the obtainment and protocol of differentiation of these cells may depend on extrinsic factors such as the tumor itself. The aim of the present study was to verify the influence of cervical neoplasia on different protocols of differentiation of monocyte-derived DCs resulting in an increased maturation phenotype. A total of 83 women were included in the study. The patients were grouped in low-grade squamous intraepithelial lesion (LSIL) (n=30), high-grade squamous intraepithelial lesion (HSIL) (n=22), cervical cancer (n=10) and healthy patients (n=21) groups...

The expression levels of cyclooxygenase (COX)-2 and the prostaglandin E2 (PGE2) content have been associated with poor prognosis in patients with colorectal cancer (CRC). There is a strong correlation between COX-2 expression and PGE2 production in tissues from CRC patients, suggesting an important role for COX-2 on the regulation of PGE2 production. Previous studies by the present authors, where CRC patients were divided into high- or low-COX-2 expressing tumors, displayed important differences in the expression levels of several transcription factors involved in carcinogenesis...

Questions of meaning and purpose in life are becoming relevant during cancer. Studies have shown that most patients have spiritual needs and that religion/spirituality can be an important ressource in coping with illness. So far, only few studies examine the psychosocial burden and the role of spiritual needs during the treatment process of patients with malignant melanoma. 22 patients were included in this study and assessed for psychosocial distress and spiritual needs while being screened for cancer metastases (t1) and 8 weeks later (t2)...

BACKGROUND: Thromboelastography is widely used as a tool to assess the coagulation status of surgical patients. It allows observation of changes in material properties of whole blood, beginning with early stages of clot formation and ending with clot lysis. However, the contact activation of the coagulation cascade at surfaces of thromboelastographic systems leads to inherent variability and unreliability in predicting bleeding or thrombosis risks. OBJECTIVES: To develop acoustic tweezing thromboelastometry as a noncontact method for perioperative assessment of blood coagulation...

Here, we demonstrate that antimicrobial peptides (AMPs) are an effective antibiofilm treatment when applied as catheter lock solutions (CLSs) against S. aureus biofilm infections. The activity of synthetic AMPs (Bac8c, HB43, P18, Omiganan, WMR, Ranalexin, and Polyphemusin) was measured against early and mature biofilms produced by methicillin-resistant S. aureus and methicillin-susceptible S. aureus isolates from patients with device-related infections grown under in vivo-relevant biofilm conditions. The cytotoxic and hemolytic activities of the AMPs against human cells and their immunomodulatory potential in human blood were also characterized...

Background: There is a need for better, less-invasive disease activity indices that provide a representative assessment of endoscopic disease activity. We developed a new clinical score that incorporates the Harvey-Bradshaw index [HBI] with modified patient-reported outcomes [PROp] and physician [clinician]-reported outcomes [PROc] and assessed its ability to measure endosopic disease activity in ileocolonic Crohn's disease [CD]. Methods: A cohort of 88 CD patients undergoing colonoscopy was accrued in a prospective fashion...

Background and Aims: Endoscopic outcomes are increasingly used in clinical trials and in routine practice for inflammatory bowel disease [IBD] in order to reach more objective patient evaluations than possible using only clinical features. However, reproducibility of endoscopic scoring systems used to categorize endoscopic activity has been reported to be suboptimal. The aim of this study was to analyse the inter-rated agreement of non-dedicated gastroenterologists on IBD endoscopic scoring systems, and to explore the effects of a dedicated training programme on agreement...

Fungi produce substances that contain pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) which bind to pattern recognition receptors, stimulating innate immune responses in humans. They also produce allergens that induce production of specific IgE. Areas Covered: In this review we cover both innate and adaptive immune responses to fungi. Some fungal products can activate both innate and adaptive responses and in doing so, cause an intense and complex health effects...

AIM: Chromosomal microarray (CMA) is an important diagnostic test for children with multiple congenital anomalies or certain developmental behavioural problems suggestive of an underlying genetic diagnosis. However, there are medical and ethical complexities to its use and few Australian policies to guide practice. We aimed to describe the current practice of Australian paediatricians in relation to CMA testing. We hypothesised that there are knowledge gaps in their use of CMA. METHODS: Online survey completed between September 2015 and January 2016 by paediatricians in secondary care settings...

A degradation product of APOE ε4-encoded apolipoprotein E protein targets mitochondria and inhibits cytochrome oxidase (COX), and autopsy brains from young adult APOE ε4 carriers show reduced COX activity. To further explore relationships between APOE alleles and COX, we measured platelet mitochondria COX activity in AD subjects with (n=8) and without (n=7) an APOE ε4 allele and found the mean COX activity, when normalized to sample total protein, was lower in the APOE ε4 carriers (p<0.05). Normalizing COX activity to citrate synthase (CS) activity eliminated this difference, but notably the mean CS activity was itself lower in the APOE ε4 carriers (p<0...

Epilepsy is a chronic neurological disorder that is increasingly prevalent in developing countries. It is critical to provide appropriate support to patients during seizures in order to prevent injuries. False beliefs regarding the etiology or pathogenesis of the epilepsy and inadequate health information may put patients with epilepsy or other seizure disorders at increased risk of injury. Our objective was to assess the level of epilepsy awareness amongst the general population in Grenada and educate the participants regarding proper first-aid measures...
