Goniolactone C, a Styryl Lactone Derivative, Inhibits PDGF-BB-Induced Vascular Smooth Muscle Cell Migration and Proliferation via PDGFR/ERK Signaling
Platelet-derived growth factor-BB (PDGF-BB) and its downstream effector, extracellular signal-regulated kinase 1/2 (ERK1/2) MAP kinase, initiate a multitude of biological effects, including vascular smooth muscle cell (VSMC) proliferation and migration, which are critical events in the initiation and development of restenosis following percutaneous transluminal coronary angioplasty (PTCA). Styr...


Evaluation of the Chemical and Antioxidant Properties of Wild and Cultivated Mushrooms of Ghana
Knowledge of the chemical composition of both wild and cultivated edible mushrooms in Ghana is limited. This study reports their nutritional value, composition in lipophilic and hydrophilic molecules, minerals and antioxidant properties. The samples were found to be nutritionally rich in carbohydrates, ranging from 64.14 ± 0.93 g in Pleurotus ostreatus strain EM-1 to 80.17 ± 0.34 g in Lentinu...
Resveratrol Trimers from Seed Cake of Paeonia rockii
In the course of screening natural products for antibacterial activities, a total acetone extract of the seed cake of Paeonia rockii showed significant effects against bacterial strains. Bioactivity-guided fractionation of the EtOAc-soluble fraction of the total acetone extract resulted in the isolation and identification of five resveratrol trimers, including rockiiol C (1), gnetin H , suffrut...


Some Observations on the Development of Superior Photocatalytic Systems for Application to Water Purification by the “Adsorb and Shuttle” or the Interphase Charge Transfer Mechanisms
Adsorb and shuttle (A/S) and interfacial charge transfer are the two major strategies for overcoming recombination in photocatalysis in this era of nanoparticle composites. Their relationships are considered here. A review of key literature is accompanied by a presentation of three new experiments within the overall aim of assessing the relation of these strategies. The cases presented include:...
Influence of Post-Treatment Operations on Structural Properties and Photocatalytic Activity of Octahedral Anatase Titania Particles Prepared by an Ultrasonication-Hydrothermal Reaction
The influence of changes in structural and physical properties on the photocatalytic activity of octahedral anatase particles (OAPs), exposing eight equivalent {101} facets, caused by calcination (2 h) in air or grinding (1 h) in an agate mortar was studied with samples prepared by ultrasonication (US; 1 h)–hydrothermal reaction (HT; 24 h, 433 K). Calcination in air at temperatures up to 1173...


Recent Advances in the Chemical Composition of Propolis
Propolis is a honeybee product with broad clinical applications. Current literature describes that propolis is collected from plant resins. From a systematic database search, 241 compounds were identified in propolis for the first time between 2000 and 2012; and they belong to such diverse chemical classes as flavonoids, phenylpropanoids, terpenenes, stilbenes, lignans, coumarins, and their pre...
Formation of Combustible Hydrocarbons and H2 during Photocatalytic Decomposition of Various Organic Compounds under Aerated and Deaerated Conditions
A possibility of photocatalytic production of useful aliphatic hydrocarbons and H2 from various organic compounds, including acetic acid, methanol, ethanol and glucose, over Fe-modified TiO2 is discussed. In particular, the influence of the reaction atmosphere (N2, air) was investigated. Different gases were identified in the headspace volume of the reactor depending on the substrate. In genera...

Modeling and Forecasting of Depletion of Additives in Car Engine Oils Using Attenuated Total Reflectance Fast Transform Infrared Spectroscopy
On average, additives make up to 7% of a typical lubricant base. Commonly, they are blended with lube oils to enhance specific features thereby improving their qualities. Ultimately, additives participate in the performance of car engine oils. Using an analytical tool, attenuated total reflectance fast transform infrared spectroscopy, various grades of car engine oils, at different mileages, we...
What affects happiness: Absolute income, relative income or expected income?
This study probes the reasons why increased income does not enhance happiness based on the effects of relative income and expected income. The study analysis is based on results from the Taiwan Social Change Survey from 1999 to 2002, using an ordered probit model. The findings demonstrate that the Taiwanese people are happier with an increase in absolute income. However, the marginal effect is ...

Tracer-based assessment of flow paths, storage and runoff generation in northern catchments: a review
We examine how tracer studies have enhanced our understanding of flow paths, residence times and sources of stream flow in northern catchments. We define northern catchments as non-glacial sites in the temperate conifer/boreal/permafrost zone, focussing our review mainly on sites in North America and Europe. Improved empirical and theoretical understanding of hydrological functioning has advanc...
The impact of US fresh milk production standards on dairy trade
We examine the impact of proposed changes in US legislation to allow greater use of concentrated dairy products when producing fresh milk commodities. Although this change will allow dairy producers to partially circumvent high tariff-rate quotas (TRQs) for fresh milk products, changes in dairy production and trade are small, reflecting limited use of concentrated dairy products as inputs to fr...

How Sustainable is the Macroeconomic Impact of Foreign Aid?
This paper examines how long the impact of foreign aid on growth lasts in recipient countries. An econometric technique is adopted which recognises that the impact of aid in the current year is a function not just of the current aid received but also of the aid received in previous years. indicate that foreign aid has a half-life of two years. In other words, half of the total impact of aid on ...
Taking the Thai trail: Attracting FDI via macro-level policy
This study reports on the establishment of an extensive and detailed composite dataset to support country-level econometric studies of FDI in Thailand. This has permitted investigation in detail, for the first time, of the key macroeconomic determinants of FDI in Thailand over the period 1970–2004. In particular, the influence of interest rates, exchange rates, volumes of trade, wage rates an...
Farm level effects of policy reforms in Germany: first empirical evidence
The farm level effects of policy reforms in agriculture have been discussed in the literature for a long time. However, empirical studies based on field data are not yet available. In this paper, the effects of the EU agricultural reforms in the last two decades and the introduction of the German Renewable Energy Sources Act on agricultural enterprises are investigated. For this, panel data of ...
India's surge in modern services exports: Empirics for policy
India's exports of modern services have grown consistently over the last three decades and more so since 199Sustaining modern services exports (MSEs), which in India enjoy comparative advantage, is important for sustaining service-led growth and maintaining stability on the external sector. In this context, we examine key drivers of India's surge in MSEs which have important implications for po...
