The aim of this study was to evaluate the effect of dietary phospholipid supplementation on laying hen performance, egg quality, and the fatty acid profile of egg yolks from hens fed a 2% Schizochytrium powder diet. Three-hundred-sixty 28-wk-old Hy-line W-36 laying hens were randomly allocated to one of the 5 dietary treatments, each treatment with 6 replicates of 12 birds each. All diets included 2% Schizochytrium powder (docosahexaenoic acid [DHA], 137.09 mg/g). The control group was not supplemented with any additional phospholipids, whereas the other 4 experimental diets were supplemented with 1,000 mg/kg choline (CHO), 1,000 mg/kg monoethanolamine (MEA), 1,000 mg/kg lysophosphatidylcholine (LPC), or 500 mg/kg LPC + 500 mg/kg MEA (LPC + MEA)...

We report the observation of a Pt layer thickness dependence on the induced interfacial Dzyaloshinskii-Moriya interaction in ultrathin Pt(d_{Pt})/CoFeB films. Taking advantage of the large spin-orbit coupling of the heavy metal, the interfacial Dzyaloshinskii-Moriya interaction is quantified by Brillouin light scattering measurements of the frequency nonreciprocity of spin waves in the ferromagnet. The magnitude of the induced Dzyaloshinskii-Moriya coupling is found to saturate to a value of 0.45  mJ/m^{2} for Pt thicknesses larger than ∼2  nm...

BACKGROUND: Development of biofuels is considered as one of the important ways to replace conventional fossil energy and mitigate climate change. However, rapid increase of biofuel production could cause other environmental concerns in China such as water stress. This study is intended to evaluate the life-cycle water footprints (WF) of biofuels derived from several potential non-edible feedstocks including cassava, sweet sorghum, and Jatropha curcas in China. Different water footprint types including blue water, green water, and grey water are considered in this study...

A series of nitrogen-rich "green" Energetic Materials (EMs), some with improved sensitivity, thermostability, and very low toxicity, were synthesized on the basis of 3,5-diamino-1,2,4-triazole (DAT) and 1,2,4,5-tetrazine building blocks. Since DAT contains several nucleophilic reactive sites, obtaining selective reactivity and specific isomeric products with 1,2,4,5-tetrazine precursors is a challenging task. We developed reaction conditions under which specific isomers could be prepared. On evaluating these compounds for their energetic properties, we found that N(5),N(5)'-(1,2,4,5-tetrazine-3,6-diyl)-bis(1H-1,2,4-triazole-3,5-diamine) 1 has very high thermostability (onset of decomposition temperature at 357 °C) and it is insensitive to impact (Im > 98 J), friction (>360 N) and electrostatic discharge (2512 mJ)...

The CDKN2A locus encodes for tumor suppressor genes p16(INK)(4a) and p14(Arf) which are frequently inactivated in human skin tumors. The purpose of this study was to determine the relationship between loss of INK4a/Arf activity and inflammation in the development of ultraviolet (UV) radiation-induced skin tumors. Panels of INK4a/Arf(-/-) mice and wild type (WT) mice were treated with a single dose of UVB (200 mJ/cm(2) ). For long-term studies, these mice were irradiated with UVB (200 mJ/cm(2) ) three times weekly for 30 weeks...

Biofuels have been seen as potential sources to meet future energy demand as a renewable and sustainable energy source. Despite the fact that the production technology of first-generation biofuels is consolidated, these biofuels are produced from foods crops such as grains, sugar cane, and vegetable oils competing with food for crop use and agricultural land. In recent years, it was found that microalgae have the potential to provide a viable alternative to fossil fuels as source of biofuels without compromising food supplies or arable land...

INTRODUCTION: Advance care planning (ACP) is an important aspect of end-of-life care that has been shown to improve patient autonomy in decision-making and reduce stress for surviving family members. Given the rapidly ageing population in Singapore, a greater emphasis on end-of-life care planning is needed. This study therefore sought to examine the awareness and attitudes of the general Singaporean community towards participating in ACP, which are not known hitherto. MATERIALS AND METHODS: A 24-item interviewer-administered questionnaire was constructed and administered via door-to-door survey amongst community-dwelling residents living in Housing and Development Board (HDB) flats across Singapore, selected via a two-stage stratified random sampling...

BACKGROUND: Increasing numbers of incidental pancreatic lesions are being detected each year. Accurate characterisation of pancreatic lesions into benign, precancerous, and cancer masses is crucial in deciding whether to use treatment or surveillance. Distinguishing benign lesions from precancerous and cancerous lesions can prevent patients from undergoing unnecessary major surgery. Despite the importance of accurately classifying pancreatic lesions, there is no clear algorithm for management of focal pancreatic lesions...

Neuroinflammation plays a central role in the etiology and progression of Alzheimer's disease (AD), a neurodegenerative disorder, characterized by a gradual loss of memory functions. Thus, it has been proposed that agents that could reduce inflammatory processes in AD brains might be useful for the treatment of the disease. Methyl jasmonate (MJ) is a bioactive compound, which has been reported to exhibit anti-amnesic and in vitro anti-inflammatory activities. In this study, we further examine its effects on the brain levels of biomarkers of neuroinflammation in lipopolysaccharide (LPS)-induced memory deficits in mice...

BACKGROUND: Previous work has demonstrated size, surface charge and skin barrier dependent penetration of nanoparticles into the viable layers of mouse skin. The goal of this work was to characterize the tissue distribution and mechanism of transport of nanoparticles beyond skin, with and without Ultraviolet Radiation (UVR) induced skin barrier disruption. Atomic absorption spectroscopy (AAS), flow cytometry and confocal microscopy were used to examine the effect of UVR dose (180 and 360 mJ/cm(2) UVB) on the skin penetration and systemic distribution of quantum dot (QD) nanoparticles topically applied at different time-points post UVR using a hairless C57BL/6 mouse model...
