In this work, voltammetric data recorded by a glassy carbon electrode (GCE) was used to investigate the interactions of tolcapone (Tasmar, TAS) with human serum albumin (HSA) at the electrode surface. The recorded voltammetric data was also combined with spectroscopic data to construct an augmented data matrix which was analysed by multivariate curve resolution-alternating least squares (MCR-ALS) as an efficient chemometric tool to obtain more information about TAS-HSA interactions. The results of MCR-ALS confirmed formation of one complex species (HSA-TAS2 ) and application of MCR-BANDS to the results of MCR-ALS confirmed the absence of rotational ambiguities and existing unambiguous and reliable results...

Peroxi-coagulation (PC) is an interesting new process that has not been widely studied in the literature. This work presents the application of this technology to treat an azo dye synthetic effluent, studying the effect of different parameters including initial pH, current density (j), initial dye concentration and supporting electrolyte. The two former variables significantly affected the colour removal of the wastewater, followed by the initial dye concentration and the kind of electrolyte, in a lesser extent...

Doxorubicin (DOX) is considered as a backbone in several chemotherapeutic regimens. Nevertheless, the reported systemic toxicity usually hampers its broad application. Interestingly, Cerium oxide nanoparticles (CeONPs) depicted promising regenerative antioxidant and hepatoprotective potentials against multiple oxidative stress-induced pathologies. Thus, the aim of the present study was to determine either CeONPs would display hepatoprotective properties once concomitantly administered with DOX or not. Male Sprague Dawley rats were divided into four groups (n = 10) in a two weeks study: Control (received saline, IP injection thrice a week), CeO (0...

BMPs and their receptors modulate the granulosa cell (GC) function in the follicle of domestic animals. Since little is known on BMPs in the buffalo, the present study was aimed to investigate the expression of BMP2, 4, 6, 7 and their receptors BMPR1A, BMPR1B, BMPR2 in the GC and theca cells (TC) of ovarian follicles and the role of BMP4 and BMP7 on buffalo GC. Follicles were classified into four groups based on size and E2 level in the follicular fluid as follows: (i) Group1(4-6 mm; <0.5 ng/mL) (ii) Group 2 (7-9 mm; 0...

BACKGROUND: People with mild multiple sclerosis (MS) often report subtle deficits in balance and cognition but display no measurable impairment on clinical assessments. We examined whether hopping to a metronome beat had the potential to detect anticipatory motor control deficits among people with mild MS (Expanded Disability Status Scale ≤ 3.5). METHODS: Participants with MS (n = 13), matched controls (n = 9), and elderly subjects (n = 13) completed tests of cognition (Montreal Cognitive Assessment (MoCA)) and motor performance (Timed 25 Foot Walk Test (T25FWT))...

Severe plastic deformation (SPD) has long been known to confer superior mechanical properties for many metals and alloys. In the general field of biomedical devices, and dental implants in particular, the superior strength of SPD-processed commercially pure (CP) titanium, that may surpass that of the stronger Ti6Al4V alloy, has been associated with a superior fatigue resistance. Such a property would make those materials both biocompatible and strong alternatives to the currently used titanium alloy. However, the fatigue characterization reported so far in the literature relies on a very small sample size, thereby precluding any meaningful statistical analysis...

Postural control undergoes rapid changes during child development. However, the influence of balance training (BT) on the compensation of perturbations has not yet been investigated in children. For this purpose, young (6.7 ± 0.6 years) and old children (12.0 ± 0.4 years) were exposed to externally induced anticipated (direction known) and non-anticipated (direction unknown) perturbations on a free swinging platform before and after either child-oriented BT (INT; young: n = 12, old: n = 18) or regular physical education (CON; young: n = 9, old: n = 9)...

The incidence of Barrett cancer is increasing rapidly and current screening protocols often miss the disease at an early, treatable stage. Volumetric Laser Endomicroscopy (VLE) is a promising new tool for finding this type of cancer early, capturing a full circumferential scan of Barrett's Esophagus (BE), up to 3-mm depth. However, the interpretation of these VLE scans can be complicated, due to the large amount of cross-sectional images and the subtle grayscale variations. Therefore, algorithms for automated analysis of VLE data can offer a valuable contribution to its overall interpretation...

In the last few years, molecular targeted therapies have replaced traditional cytotoxic chemotherapy in the fight against many cancers to the extent that our understanding of tumor biology has become more sophisticated. This shift has markedly changed adverse event profiles, compared to cytotoxic chemotherapy, affecting a diverse range of organ systems. Everolimus was approved by the FDA in 2011 for the treatment of progressive pancreatic NE tumors (Yao, 2011; Jensenn, 2012). It is an inhibitor of mammalian target of rapamycin (mTOR) and exhibits antitumor activity via disruption of various signaling pathways and it's used in the treatment of advanced renal cell cancer, breast cancer and neuroendocrine tumors (NET); it's used also as anti-rejection agent for transplantation but with lower doses for anti-rejection (1...

Infection with Aphanomyces invadans is one of the most destructive diseases of freshwater fishes. Indian major carps, the dominant cultured species in the Indian sub-continent are highly susceptible to this disease. Till date, there is no effective treatment for control of this disease and immunization can be one of the strategies to reduce disease-related losses. In the present study, inactivated germinated zoospores of A. invadans were evaluated as antigen in conjunction with and without adjuvant Montanide™ ISA 763 A VG, for assessing their efficacy in rendering protection against A...

Although it is widely thought that childhood levels of cardiovascular (CV) risk factors are related to adult CV disease, longitudinal data directly linking the two are lacking. This paper describes the design and organization of the International Childhood Cardiovascular Cohort Consortium Outcomes Study (i3C Outcomes), the first longitudinal cohort study designed to locate adults with detailed, repeated, childhood biological, physical, and socioeconomic measurements and a harmonized database. I3C Outcomes uses a Heart Health Survey (HHS) to obtain information on adult CV endpoints, using mail, email, telephone, and clinic visits in the United States (U...

Today, due to the increase in the population, the growth of industry and the variety of chemical compounds, the quality of drinking water has decreased. Five important river water quality properties such as: dissolved oxygen (DO), total dissolved solids (TDS), total hardness (TH), alkalinity (ALK) and turbidity (TU) were estimated by parameters such as: electric conductivity (EC), temperature (T), and pH that could be measured easily with almost no costs. Simulate water quality parameters were examined with two methods of modeling include mathematical and Artificial Neural Networks (ANN)...

BACKGROUND: Different diffusion tensor imaging (DTI) has been used to estimate corticospinal tract (CST) structure in the context of stroke rehabilitation research. However, there is no gold standard for the estimate of CST structure in chronic stroke survivors. This study aims to determine the most accurate DTI-derived CST estimate that is associated with a clinical motor outcome measure. METHODS: We obtained imaging and behavioral data from a phase-I stroke rehabilitation clinical trial...

INTRODUCTION: Single institution studies suggest a benefit of a week of preoperative antibiotics prior to percutaneous nephrolithotomy (PCNL). These studies are limited by lower quality methodology such as the inclusion of heterogeneous populations or the use of non-standard definitions of sepsis. The American Urological Association (AUA) Best Practice Statement recommends <24 hours of IV antibiotics, but no other data exist about the duration/benefit of preoperative antibiotics. We sought to perform a rigorous (using CONSORT guidelines), multi-institutional trial to assess preoperative antibiotics in PCNL patients at low risk of developing infections...

BACKGROUND: There are patients born with pulmonary atresia and a ductus arteriosus or hemi-truncus to one lung and major aortopulmonary collateral arteries (MAPCAs) to the contralateral lung. The purpose of this study was to review our surgical results for this relatively rare subset of patients. METHODS: This was a retrospective review of 35 patients with ductus/hemi-truncus in association with pulmonary atresia with ventricular septal defect and MAPCAs. Our surgical algorithm is bifurcated into two strategies: 1) patients with "favorable" MAPCAs are candidates for single stage complete repair, and 2) patients with "unfavorable" MAPCAs undergo a staged approach...

OBJECTIVES: Alpha-fetoprotein (AFP) measurement in pericardial, peritoneal (ascites), and pleural fluids is sometimes requested by clinicians as supportive evidence in the evaluation of suspected malignancy. As commercially available, Food and Drug Administration (FDA)-cleared AFP assays are not validated for these fluid types, laboratories must complete additional validation studies to comply with regulatory requirements for body fluid testing. The objective of this study was therefore to conduct a matrix evaluation for these body fluid types using the Beckman Access AFP assay on the UniCel DxI 800 immunoassay system...
