BACKGROUND: Up to 20% of patients experience only partial pain relief after percutaneous cordotomy for cancer pain. OBJECTIVE: To determine whether diffusion tensor imaging (DTI) can quantify neural ablation and help evaluate early postoperative outcomes after cordotomy. METHODS: Patients undergoing percutaneous CT-guided cordotomy for intractable cancer pain were prospectively studied. Pre- and postoperative assessment was made using the visual analog scale (VAS) on pain and the pain severity scores of the Brief Pain Inventory Short Form...

The epithelial cell adhesion molecule (EpCAM) is overexpressed in a wide variety of tumor types, including peritoneal carcinomatosis (PC) from gastrointestinal and gynecological malignancies. To develop a chimeric antigen receptor T (CART) cell therapy approach to treat patients with end-stage PC, we constructed third generation CARs specific to EpCAM using the 4D5MOC-B single chain variable fragment. CART cells were generated with lentiviral transduction and exhibited specific in vitro killing activity against EpCAM-positive human ovarian and colorectal cancer cells...

Cellular immunotherapy is emerging as a potential immunotherapeutic modality in multiple myeloma (MM). We have developed potent immunotherapeutic agent (VAX-DC/MM) generated by dendritic cells (DCs) loaded with autologous myeloma cells irradiated with ultraviolet B. In this study, we evaluated the safety and efficacy of VAX-DC/MM in patients with relapsed or refractory MM. This trial enrolled relapsed or refractory MM patients who had received both thalidomide- and bortezomib-based therapies. Patients received the intradermal VAX-DC/MM injection every week for 4 weeks...

Most therapeutic attempts to prevent the progression of kidney diseases have been based on interventions to inhibit the production of transforming growth factor-β (TGF-β). Thrombospondins (TSPs) play an important role in activating TGF-β. In the healthy kidney, two TSPs are expressed, TSP1 and TSP2, which exert contrasting effects. While TSP1 is a major activator of TGF-β in renal cells and exerts pro-inflammatory effects both in vitro and in vivo, TSP2 lacks the ability for TGF-β activation but regulates matrix remodeling and inflammation in experimental kidney disease...

MOTIVATION: Single-cell RNA sequencing (scRNA-seq) is increasingly used to study gene expression at the level of individual cells. However, preparing raw sequence data for further analysis is not a straightforward process. Biases, artifacts and other sources of unwanted variation are present in the data, requiring substantial time and effort to be spent on pre-processing, quality control (QC) and normalization. RESULTS: We have developed the R/Bioconductor package scater to facilitate rigorous pre-processing, quality control, normalization and visualization of scRNA-seq data...

Rates of human papillomavirus (HPV) vaccine series completion among adolescent Hispanic females in Texas in 2014 (∼39%) lag behind the Healthy People 2020 goal (80%). This qualitative study identifies Hispanic mothers' salient behavioral, normative and control beliefs regarding having their adolescent daughters complete the vaccine series. Thirty-two mothers of girls (aged 11-17) that had received at least one dose of the HPV vaccine, completed in-depth interviews. Six girls had received one dose of the HPV vaccine, 10 girls had received two doses, and 16 girls had received all three doses...

Myocardial infarction due to ischemia accounts for majority of deaths among cardiovascular disorders. Isoproterenol (ISO) induced myocardial infarction and the protection offered by piperine was investigated in the present report. Lipid profile analysis by determining the levels of cholesterol, phospholipids, triglycerides and lipoproteins in serum and heart tissues showed anti-dyslipidemic action of piperine against ISO induced myocardial injury by modulating the ISO induced altered lipid profiles, maintaining to near control values...

The adaptation of the membrane distillation process as a low-cost and sustainable approach to biosolids drying and stabilization is investigated, which may have application in container-based sanitation systems proposed in low-income urban regions. Three-layer laminated, breathable, hydrophobic membranes enclose the biosolids, facilitating drying but preventing transport of contaminants. The membranes used in this process are non-wetting with pore spaces that only allow vapor transport. Water vapor can be expelled due to a moderate vapor pressure gradient...

Chlorogenic acid (CGA), one of the most abundant dietary polyphenolic compounds, has been reported to exhibit anti-inflammatory ability. However, the hepatoprotective effects and molecular mechanisms of CGA on concanavalin A (Con A)-induced hepatitis have not been explored. In the present study, we found that pretreatment with CGA dose-dependently inhibited the elevation of plasma aminotransferases and alleviated hepatic pathological damage as well as hepatocyte apoptosis in Con A-exposed mice. Additionally, CGA markedly suppressed the production of serum tumor necrosis factor (TNF)-α and interferon (IFN)-γ, alleviated the infiltration of hepatic macrophages, neutrophils, and activated CD4(+) T lymphocytes in Con A-primed mice...

Procyanidins are widely found in plants and have anti-inflammatory activities. Procyanidin B2 (PCB2) inhibits production of proinflammatory cytokines in macrophages. However, there has been no study that has attempted to determine the effects of PCB2 gallates on T cell functions. In the present study, murine splenocytes were isolated and treated with PCB2 or PCB2 gallates in the presence of an anti-CD3 monoclonal antibody (mAb). PCB2 gallates, but not PCB2, inhibited proliferation and T cell activation of splenocytes after stimulation with the anti-CD3 mAb...

PURPOSE: Fractures in long span provisional/interim restorations are a common complication. Adequate fracture toughness is necessary to resist occlusal forces and crack propagation, so these restorations should be constructed with materials of improved mechanical properties. The aim of this study was to investigate the possible reinforcement of neat silica nanoparticles and trietoxyvinylsilane-modified silica nanoparticles in a PMMA resin for fixed interim restorations. MATERIALS AND METHODS: Composite PMMA-Silica nanoparticles powders were mixed with PMMA liquid and compact bar shaped specimens were fabricated according to the British standard BS EN ISO 127337:2005...

Kinematic analysis of the trunk during cerebral palsy (CP) gait has been well described. In contrast, movement of the lumbar spine is generally ignored. This is most likely due to the complex nature of the spine. As an alternative to using complex sensor protocols, this study modelled the lumbar region as a single segment and investigated characteristic patterns of movement during CP gait. In addition, the impact of functional level of impairment and the relationship with lower lumbar spinal loading were examined...

The criminal justice system tends to emphasize external contingencies (e.g., fees, jail time) to motivate offender compliance. However, people's reasons for desistance vary considerably. This study evaluated the acceptability, utility, and predictive validity of questions that ask about people's reasons for wanting to successfully complete probation. Substance-using probationers (N=113) participated in a web-based computer intervention that targeted substance use and treatment initiation. Questions around seven dimensions of reasons for completing probation were developed to provide tailored feedback during the web-based program...

OBJECTIVE: It has been reported that gastroschisis is associated with low maternal body mass index (BMI). We tested this hypothesis in the UK. STUDY DESIGN: We studied cases of gastroschisis ascertained from the regional fetal congenital anomaly register. We compared each affected mother with two controls from the birth register and maternity database. The first control was the next mother to deliver in the hospital, representing the normal population of mothers...

CYP20A1 is a member of the cytochrome P450 (CYP) superfamily, identified as an orphan P450 without any assigned biological function; hence, its continued status as an "orphan" gene. In order to address this shortcoming in our understanding of this superfamily, we sought to characterize the CYP20A1 gene in the copepods Tigriopus japonicus (Tj-CYP20A1) and Paracyclopina nana (Pn-CYP20A1) at their mRNA transcriptional level. We assessed the response of this gene's expression in various developmental stages and in response to treatment with bisphenol A (BPA), 2, 2', 4, 4'-tetrabromodiphenyl ether (BDE-47), and water accommodated fractions (WAFs) of crude oil...

Oxidative stress causes endothelial death while underlying mechanisms remain elusive. Herein, the pro-death effect of tert-butyl hydroperoxide (t-BHP) was investigated with low concentration (50μM) of t-BHP (t-BHPL) and high concentration (500μM) of t-BHP (t-BHPH). Both t-BHPL and t-BHPH induced endothelial cell death was determined. T-BHPL induced caspase-dependent apoptosis and reactive oxygen species (ROS) generation, which was inhibited by N-acetyl-L-cysteine (NAC). Furthermore, NADPH oxidase inhibitor diphenyleneiodonium (DPI), NOX4 siRNA, and NOX4 inhibitor GKT137831 reduced t-BHPL-induced ROS generation while mitochondrial respiratory chain inhibitors rotenone (Rot), 2-thenoyltrifluoroacetone (TTFA), and antimycin A (AA) failed to do so...

DLNO/DLCO directly measures the ratio of the diffusing capacities of the lung for nitric oxide (NO) and carbon monoxide (CO). In terms of the Roughton and Forster, 1957; equation, 1/DL=1/Dm+1/θVc, where Dm is the membrane (Dm) and θVc is the red cell component of the overall diffusing conductance (DL), DLNO mostly reflects the Dm component and DLCO the θVc red cell component. The DLNO/DLCO ratio is positively related to the DmCO/Vc ratio and the CO red cell resistance (1/θCOVc) as a percentage of the total resistance (1/DLCO), independent of the absolute values of DLNO or DLCO...

The cellulases from Glycoside Hydrolyses family 12 (GH12) play an important role in cellulose degradation and plant cell wall deconstruction being widely used in a number of bioindustrial processes. Aiming to contribute toward better comprehension of these class of the enzymes, here we describe a high-yield secretion of a endoglucanase GH12 from Aspegillus terreus (AtGH12), which was cloned and expressed in Aspergillus nidulans strain A773. The purified protein was used for complete biochemical and functional characterization...
