Antioxidant Potential and Antitumour Activities of Nendran Banana Peels in Breast Cancer Cell Line

The present study was aimed to evaluate the antioxidant and antitumor activities of the aqueous methanol extract of Nendran banana peel as a valuable source for bioactive compounds against cancer. Free radical scavenging activity of the peel extracts was evaluated using 1,1-diphenyl-2-picrylhydrazyl and ferric reducing antioxidant power assay. The antitumor activity on MCF-7 breast cancer cell line was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and ethidium bromide/acridine orange staining assay. Extract of banana peel was more efficient in reducing ferric ion with the increase in concentration and exhibited IC50 180.33 µg/ml, free radical inhibition activity under 2,2-diphenyl-1-picrylhydrazyl hydrate assay. Flavonoid content was high (51.47 µg/ml) in the peel extract, which could have contributed to the antioxidant activity. The antioxidant enzyme concentration such as ascorbate peroxidase, catalase, peroxidase and superoxide dismutase were found higher in the fruit pulp than peel. As the concentration of extract increased from 20 to 200 μg/ml, the cell viability of MCF-7 decreased from 91.14 to 24.7%. The IC50 values of plant extract-treated cells (120.6 μg/ml) showed typical apoptotic and necrotic morphological features such as condensed nuclei, membrane blebbing and formation of apoptotic bodies. This indicated the efficiency of sample against breast cancer with the highest inhibition of growth.
Annual Review of Biophysics Giant Vesicles and Their Use in Assays for Assessing Membrane Phase State , Curvature , Mechanics , and Electrical Properties

Giant unilamellar vesicles represent a promising and extremely useful model biomembrane system by providing the possibility for systematic measurements of mechanical, thermodynamic, electrical, and rheological properties of lipid bilayers as a function of membrane composition, surrounding media, and temperature. The most important advantage of giant vesicles over other model membrane systems is that the membrane responses to external factors such as ions, (macro)molecules, hydrodynamic flows, or electromagnetic fields can be directly observed under the microscope. Here, we briefly review approaches for giant vesicle preparation and describe several assays used for deducing the membrane phase state and measuring a number of material properties, with further emphasis on membrane reshaping and curvature. 93 Review in Advance first posted on February 27, 2019.

Experimental Study of Indices for Evaluating the Augmented Reality System from the Viewpoint of Human Centered Design

Applying augmented reality to a work support system is expected to decrease human errors when practicing the maintenance of equipments of nuclear power plants. It is necessary to establish the indices to evaluate the system from the viewpoint of human centered design in order to develop such a system. In this study, therefore, the authors investigated the applicability of some indices to evaluate the system. As a result, it was revealed that task completion time and the score of NASA-TLX are appropriate indices.
Prototyping a Capacitive Sensing Device for Gesture Recognition

Capacitive sensing is a technology that can detect proximity and touch. It can also be utilized to measure position and acceleration of gesture motions. This technology has many applications, such as replacing mechanical buttons in a gaming device interface, detecting respiration rate without direct contact with the skin, and providing gesture sensing capability for rehabilitation devices. In this thesis, an approach to prototype a capacitive gesture sensing device using the Eagle PCB design software is demonstrated. In addition, this paper tested and evaluated the resulting prototype device, validating the effectiveness of the approach.
Serum Amyloid 1-42 Autoantibody Levels n Alzheimer ’ s Disease , Determined by a Newly eveloped ImmunoPrecipitation Assay with adiolabeled Amyloid 1-42 Peptide

ackground: Autoantibodies against amyloid (A ) peptide found in patients with Alzheimer’s disease (AD) also occur naturally n the general population independently of the cognitive status. ethods: We compared serum A 1-42 autoantibody levels (A 1-42-AL) of 96 AD patients and 30 healthy elderly control subjects (HC), ssessing their diagnostic value for AD with a newly developed immunoprecipitation assay with radiolabeled A 1-42 peptide. esults: We found a highly significant decrease of A 1-42-AL in AD patients (p .001) independently of age, cognitive status, and polipoprotein Eε4 carrier status. Amyloid 1-42 autoantibody levels were correlated with gender in AD, with a higher level occurring n women. When A 1-42 autoantibody sensitivity (specificity) was set 80%, specificity (sensitivity) was below 50% to correctly allocate atients and healthy control subjects. onclusions: Our data indicate a potentially pathophysiologic decrease of serum A 1-42 antibodies in AD. Amyloid 1-42 antibodies n the serum alone, however, seem not to be useful as a diagnostic marker of AD.

Effect of Temperature and Storage Period on Seed Germination and Some Morphological Characteristics of Rice ( Oryza sativa L . ) RD 6 cultivar

Deterioration of rice seed was caused by high temperature and humidity during storage. Seed deterioration involves the reduction of seed germination, vigorous seedling and survival rate. Aim of this research was to investigate seed germination percentage, survival percentage and some morphological characteristics of Oryza sativa L. RD6 cultivar. Paddy was stored under -20, -10, 4 and 25oC for 0, 2, 4, 6 and 8 months. The result showed that the highest germination percentage (100%) of RD6 was recorded in all treatments that stored at 25oC. The highest survival percentage (100%) of RD6 was found in treatment that stored at -20 oC for 6 months. Morphological characteristics of seedlings in all treatments were not significantly different. This data may be useful for rice seed storage research in the future.
A 200W MPPT Boost Converter for BIPV Applications with Integrated Controller

The proposed solar power converter realizes boost-type DC-DC conversion with maximum power point tracking (MPPT) and comprises a proposed 1.5mm2 chip and less discrete components. Measured with a commercial solar array simulator (SAS), it achieves high tracking and high conversion efficiencies, which outperforms current state-of-the-arts. This converter can not only be used in stand-alone systems but also in grid-connected systems if it is connected to a DC/AC inverter. Further, it can be applied to household and vehicle products, as well as building-integrated photovoltaics (BIPV).
Evaluation of a physically-based base flow time constant in ORCHIDEE Land-Surface Model at global scale

Introduction Base flow is an important source of water to rivers representing the part of the stream flow that is sustained by groundwater discharge. Although an important component on water management, and a key variable in Land Surface Models (LSMs), base flow quantification depends on estimation, since there are no available techniques to directly measure it. Large scale LSMs use two main approaches to estimate base flow: by solving the diffusion equation numerically, or by using a linear reservoir that relies on a base flow time constant (τ). The estimation of base flow from the diffusion equation depends on numerical methods that are computational demanding, and becomes difficult at large scales. LSMs with a linear reservoir depend on observation data to calibrate τ, which are scarce with increasing scale. To overcome the lack of observed data, a common practice is to extrapolate calibrated values over a region to the entire globe, as in [1] with ORCHIDEE (using a τ of 67 days in average that varies with topography, calibrated over the Senegal basin) or locally with CLSM in [2] (using a τ of 700 days, calibrated over the Somme basin). The calibrated values are in agreement with τ obtained from studies of river discharge recession analysis at the basin scale. However, the extrapolation over large regions neglects natural hydrogeological heterogeneities, a problem that is not observed with the diffusion equation. To combine the simplicity of a linear reservoir with the hydrogeological properties of the diffusion equation, another approach is to use an analytical solution of the diffusion equation to estimate τ. [3] proposed a linear solution of the Boussinesq equation for sloping, unconfined, isotropic and homogeneous aquifers that depends on the effective porosity, transmissivity, slope, and drainage density. In this framework, the spatial variations of τ results in a physical way from hydrogeological heterogeneities, but τ can be overestimated up to five orders of magnitude depending on the data used on its estimation when compared to literature values. This raises a major question: can such a physically-based τ improve the base flow dynamics in large-scale LSMs? In this work we use the LSM of the Institute Pierre Simon Laplace called ORCHIDEE to evaluate the effect of a physically-based τ on river discharge simulations.
Strain engineering the work function in monolayer metal dichalcogenides

We use first-principles density functional theory to investigate the effect of both tensile and compressive strain on the work functions of various metal dichalcogenide monolayers. We find that for all six species considered, including MoS2, WS2, SnS2, VS2, MoSe2 and MoTe2, that compressive strain of up to 10% decreases the work function continuously by as much as 1.0 eV. Large enough tensile strain is also found to decrease the work function, although in some cases we observe an increase in the work function for intermediate values of tensile strain. This work function modulation is attributed to a weakening of the chalcogenide-metal bonds and an increase in total energy of each system as a function of strain. Values of strain which bring the metal atoms closer together lead to an increase in electrostatic potential energy, which in turn results in an increase in the vacuum potential level. The net effect on the work function can be explained in terms of the balance between the increases in the vacuum potential levels and Fermi energy.
Review of complimentary therapies for common ocular disorders

PURPOSE: To inform eye care providers of the complimentary and alternative medical (CAM) supplements used by patients for the prevention and treatment of common ocular conditions. DESIGN: Retrospective literature review. METHODS: Studies and information found in published journals, reference texts, and selected websites were researched to find commonly cited CAM supplements used in the prevention and treatment of cataracts, glaucoma, age-related macular degeneration (ARMD), diabetic retinopathy (DR), and common "red eye" conditions. The literature was concisely reviewed to extract indication of use, mechanism of action, condition specific dosages, the recommended dietary allowance (RDA) if available, drug interactions, and absolute contraindications for each CAM supplement. RESULTS: Available evidence of CAM use for the ocular conditions described is variable. Therefore, "gold standard" routine CAM treatments for most of the specific ocular conditions described do not exist. Information and recommendations provided herein are simply a compilation of the literature, and are in no way supported or refuted by the authors. CONCLUSION: The use of CAM therapies in the United States is a multi-billion dollar industry. It is the aim of this review to equip eye care providers with essential knowledge of the common vitamins, minerals, and herbs used for eye disease to properly counsel patients in making appropriate and safe choices.
Who Wants Power More , Men or Women ? A Cross-Cultural Comparison ( U . S . V . Spain )

These two studies examined gender differences of various types of leaders in the United States and Spain in acquiring and exerting power. This paper followed, at least obliquely, the format used by French and Raven (1959) when examining the impact of gender differences regarding the use of referent, expert, reward, coercive, and legitimate power. The research question, for both studies, was: Do men or women, from a cross-cultural standpoint, use power more; and what technique do they employ most often to achieve success? The results from both studies, suggest that women want power more than men do in order to make a positive contribution to the organization. The findings also indicate that a high percentage of people, at least in the United States, have witnessed leaders, when exerting power, use coercion, rewards, special knowledge, legitimacy, and respect to get subordinates to comply with their requests.
Antibacterial action of trimethoprim-sulfamethoxazole.

Many publications have reported on the mode of action of sulfamethoxazole (SMZ) and trimethoprim (TMP) on the folic-acid metabolism of bacteria. The results were usually performed with model strains and a specific, often synthetic culture media. Therefore, we decided to test a number of different species with commercially available culture media and to examine the constancy of the activity of TMP-SMZ and its components. In the diffusion test (figure 1), the antagonistic action of SMZ p-aminobenzoic acid (PABA) against SMZ is accepted, whereas it seems that there is no antagonism against the combination. Accurate examination, however, does show that the PABA concentration in the medium affects the
Contrast Use in CTA Applications

In July 2006, I served as the moderator of the seventh in a series of CTA Forums on the use of intravenous contrast in computed tomographic angiography (CTA). The proceedings of each of these Forums have been published as a special supplement to Applied Radiology, in print or online, or both. The July 2006 CTA Forum focused on cardiac CT, exploring the influence of advancing CT technology not only on contrast medium administration, data acquisition, and data postprocessing, but also on the expanding role of cardiac CT in clinical medicine. Cardiac imaging is both the most demanding CT application and the greatest beneficiary of advances in CT technology. Indeed, cardiac CT is driving innovation, spurring not only foreseeable improvements in temporal and spatial resolution, but also entirely new ideas, such as dualenergy CT. The results are increasing diagnostic accuracy, increasing ease of use, and identifying a wider range of patients for whom cardiac CT is the noninvasive imaging modality of choice. The goals of the July Forum, and of this supplement, are to: • Review the current state of the art of cardiac CT, including its clinical applications; • Provide key information on the selection and use of contrast media in multislice cardiac CTA procedures; • Review when and why to use cardiac CT, particularly coronary CTA; • Provide “how-to” information for performing cardiac CTA studies, including contrast administration, image acquisition, and scan interpretation; and • Provide a better understanding of the challenges of offering cardiac CTA as a clinical service. This supplement comprises an impressive array of review articles by a distinguished panel of experts. In addition to my own overview on the state of the art of cardiac CT, Jill E. Jacobs, MD (from New York University Medical Center, New York, NY) authors an excellent review on how to perform coronary CTA; Stephan Achenbach, MD (from the University of Erlangen–Nürnberg, Erlangen, Germany) crafts a Top 10 list of indications for coronary CTA; and James K. Min, MD (from the Weill Medical College of Cornell University, New York-Presbyterian Hospital, New York, NY) compares coronary CTA and invasive angiography. Samuel Wann, MD, MACC (from The Wisconsin Heart Hospital, Milwaukee, WI) reviews the use of cardiac CT for risk stratification, while Matthew Budoff, MD (from the Los Angeles Biomedical Research Institute at Harbor–UCLA Medical Center, Torrance, CA) describes the emerging use of cardiac CT in the emergency room, including coronary calcium scoring, coronary CTA, and triple rule-out studies. Finally, Chip Gilkeson, MD (from Case Western Reserve University School of Medicine and University Hospitals of Cleveland, Cleveland, OH) describes the growing role of cardiac CT in discovering congenital heart disease in adults, many of whom come to the emergency room with chest pain. I would like to thank GE Healthcare for sponsoring the CTA Forum and for providing an educational grant in support of this publication, Anderson Publishing for producing this special supplement, and the Forum participants for preparing a comprehensive overview of cardiac CTA.
Math Anxiety and Math Ability in Early Primary School Years

Mathematical learning disabilities (MLDs) are often associated with math anxiety, yet until now, very little is known about the causal relations between calculation ability and math anxiety during early primary school years. The main aim of this study was to longitudinally investigate the relationship between calculation ability, self-reported evaluation of mathematics, and math anxiety in 140 primary school children between the end of first grade and the middle of third grade. Structural equation modeling revealed a strong influence of calculation ability and math anxiety on the evaluation of mathematics but no effect of math anxiety on calculation ability or vice versa—contrasting with the frequent clinical reports of math anxiety even in very young MLD children. To summarize, our study is a first step toward a better understanding of the link between math anxiety and math performance in early primary school years performance during typical and atypical courses of development.
Gram Negative Peritonitis

In all forms of maintenance peritoneal dialysis chronic intermittent, continuous ambulatory, and continuous cyclic peritonitis remains a frequent and serious complication (1-4). Early reports of continuous ambulatory peritoneal dialysis described an infection rate of one episode every two patient months (1). More recently the incidence of peritonitis has decreased, probably because dialysate delivery systems and catheter care techniques have improved yet infection continues to be a major unresolved problem (4). The diagnostic findings, discussed elsewhere in detail (4). consist essentially of cloudy dialysate fluid with or without abdominal pain. The diagnosis is confirmed by finding a dialysate cell count over 100 white cells per cubic millimeter and by culture and sensitivity testing. In earlier studies of peritoneal dialysis for acute renal failure, enteric, gram-negative, and anaerobic bacteria caused most cases of peritonitis (5). Following the advent of indwelling catheters and improved techniques, grampositive bacteria (especially staphylococci and streptococci) were reported to account for up to 75% of the cases of peritonitis, while gram-negative bacteria were seen in 15 to 25% and fungi in less than 5% (6). Others, however, have estimated that gram-negative organisms may cause as many as 40% of all episodes (1). In our series of over 60 patients, gram negative bacteria were responsible for 23% of all episodes of peritonitis, the incidence steadily increasing since the beginning of our program in 1978. This trend has been also confirmed by Nolph et al., who recently reported an increase in gramnegative peritonitis in the fourth year of their continuous ambulatory peritoneal dialysis program (8). In patients entering a chronic peritoneal dialysis program it is unusual for gram-negative organisms to be the cause of the initial episode of peritonitis. In our series, less than 20% of all gram-negative peritonitis presented as the initial episode and most cases followed multiple episodes (average 2.4 per patient) of gram-positive infection. Fenton et al recently reported similar findings (9). In their series of 31 episodes of gram-negative peritonitis, 26 were preceded by gram-positive infections or by antibiotics used for other infections. The clinical presentation of gram-negative peritonitis is indistinguishable from that of infection with gram-positive organisms (10). All of our patients had cloudy dialy-
