BACKGROUND Reports of high levels of use of protein powders and nutritional supplements among young men is a concern because these substances may act as a gateway for the use of drugs and illegal substances to enhance appearance or sports performance. The aim of this study was to investigate the relationship between body dissatisfaction, weight change behaviors, supplement use, and attitudes to...

BACKGROUND An emerging body of evidence indicates that early-life arsenic (As) exposure may influence the trajectory of health outcomes later in life. However, the mechanisms underlying these observations are unknown. OBJECTIVE The objective of this study was to investigate the influence of prenatal As exposure on global methylation of cord blood DNA in a study of mother/newborn pairs in Matl...

Successful new products generate both trial and repeat purchases. While trial is based on expectations about product quality, repeat depends largely on satisfaction as assessed by the gap between observed and expected quality. As a consequence, companies make a tradeoff between setting expectations too high, resulting in strong trial but little repeat business, and too low, which enhances repea...

BACKGROUND We developed microbiological assays (MBAs) to identify determinants and to establish reference values for cobalamin bound to transcobalamin [holotranscobalamin (holoTC)] and total TC in plasma. METHODS We captured holoTC with magnetic beads with TC antibodies and used a conventional MBA for cobalamin measurements. Total TC was determined as holoTC after TC was saturated with cyanoc...

This study aims to determine the absorption of water detergent waste using spinach (ipomoea aquatica). experimental used a randomized block design. Water samples were planted with plants according research Detergent concentrations observed MBAS (Methylene Blue Active Substance) method. The results showed that was able reduce concentration and improve quality parameters (DO, BOD, COD). After tre...

Solving the atomic structure of metallic clusters is fundamental to understanding their optical, electronic, and chemical properties. Herein we present the structure of the largest aqueous gold cluster, Au146(p-MBA)57 (p-MBA: para-mercaptobenzoic acid), solved by electron micro-diffraction (MicroED) to subatomic resolution (0.85 Å) and by X-ray diffraction at atomic resolution (1.3 Å). The 146 ...

Traditional multicast authentication schemes manage the different involvement of the receivers by letting the sender: Choose the block size, divide a multicast stream into blocks, connect each block with a signature, and spread the effect of the Signature across all the packets in the block. The relationship between packets tends to packet loss which is very common via internet and wireless com...
