The study demonstrates the Fenton reaction, which is carried out using the Fenton reagent that is used for groundwater and soil remediation. The Fenton reaction can be implicated in DNA damage, Alzheimer's disease, cardiovascular disease and ageing in general.

Many carbonyl substrates of oxidoreductase enzymes undergo hydration and enolization so that these substrate systems are partitioned between keto, hydrated (gem-diol), and enol forms in aqueous solution. Some oxidoreductase enzymes are subject to inhibition by high concentrations of substrate. For such enzymes, two questions arise pertaining to…

This laboratory experiment was designed to demonstrate the application of immobilized galactosidase in food industry to hydrolyze raffinose family oligosaccharides in soymilk. This laboratory experiment was conducted for postgraduate students of biochemistry and developed for graduate and undergraduate students of biochemistry, biotechnology,…

The study describes the development of new biosensors based on metal nanoparticles because of its high surface area and large binding ability. The adopted procedure is extremely simple and versatile and can be used in various applications of electrochemistry.

Students' reactions to classroom learning and the mastery of science vary along a wide spectrum of attitudes and emotions. In particular, we argue here that how learners encounter and learn subject matter is a function of their level of cognitive development. We describe the stages of cognitive development based on the work of William Perry and…

Neuroelectric and imaging studies of meditation are reviewed. Electroencephalographic measures indicate an overall slowing subsequent to meditation, with theta and alpha activation related to proficiency of practice. Sensory evoked potential assessment of concentrative meditation yields amplitude and latency changes for some components and…

Stress can enhance or impair memory performance. Both cortisol release and sympathetic nervous system responses have been implicated in these differential effects. Here we investigated how memory retrieval might be affected by stress-induced cortisol release, independently of sympathetic nervous system stress responses. Thirty-two healthy…

The good, bad and ugly gifts from the mother earth are highlighted. Olive oil, rice seedling blight, and Borrelia burgdorferi, respectively are the good, bad and ugly gifts from the mother earth.

Can genetic evolution be controlled by man in a manner which does not violate a civilized, humane, and democratic ethos? The genetics of health and illhealth and of normal variation are discussed with respect to this question. (PEB)

Examined were medical records of 265 hyperkinetic children (7-9 years old). Clinical blood chemistries, hematology, and 5-hour glucose tolerance test (GTT) results indicated that hematocrit levels were low in 27% of the Ss, eosinophil levels were abnormally high in 86% of the Ss, and GTT results were abnormal in a maority of Ss.

Biorhythm comes from the Greek words for life and regulated beat. The science of biorhythm is concerned with the rhythmic cycles of physical, emotional, and intellectual life. These cycles have lengths of 23, 28, and 33 days respectively. During the first half of each cycle, energy is high. During the low period, second phase abilities, feelings,…

The nature of the work performed by biologists and biochemists is described in general terms, and for the subcategories such as agronomists, pharmacologists and entomologists. The types of employment opportunities, the necessary training the employment outlook and typical salaries and working conditions are described. Addresses for requesting…

Information on the centromere, or kinetochore, varies from textbook to textbook. This article reviews and reconsiders how this body is defined. (BB)
