Fast, reliable, well-resolved latent fingerprints can be planted by applying a thin coating of a 50:50 mixture of hand lotion and food-grade protein powder. Fingerprints can be revealed with iodine fuming or ninhydrin staining. This low-cost alternative to commercial latent print pads can be used in a variety of classroom or public settings where…

The purpose of this study was to determine the use of nutrition support products by male and female athletes who are involved in taekwondo and their level of knowledge in this respect. The sample group was formed with male and female (n=300) athletes who are actively involved in taekwondo. 300 of the collected questionnaires, which were determined…

Laboratory exercises focused on protein quantification are frequently conducted in traditional undergraduate biochemistry laboratory curriculum. The laboratory course described here is designed to provide students with experience in measurement of protein content in milk powder by moving reaction boundary titration (MRBT), a new rapid technique…

Coagulation is an important process in the context of water purification; and the seed protein of the moringa tree ("Moringa oleifera") is a remarkably effective coagulant. The laboratory course described here is designed to provide high-school students with a stepwise, hands-on experience in investigating the protein-rich coagulant…

Stunting has been negatively associated with children's development. We examined the range of height by testing hypotheses: (a) height is positively associated with children's development, with associations moderated by inflammation and (b) home environments characterized by nurturance and early learning opportunities is positively associated with…

Solid-state nuclear magnetic resonance (NMR) spectroscopy finds growing application to inorganic and organic materials, biological samples, polymers, proteins, and cellular membranes. However, this technique is often neither included in laboratory curricula nor typically covered in undergraduate courses. On the other hand, spectroscopy and…

In 1987, when the U.S. Centers for Disease Control and Prevention recommended the use of universal precautions in response to the HIV/AIDS epidemic, the demand for medical gloves dramatically increased. Unfortunately, the manufacturing techniques for the most widely-used gloves--natural rubber latex--also changed, in order to expedite production.…
