Chemolithoautotrophy based on reduced inorganic minerals is considered a primitive energy transduction system. Evidence that a high number of meteorites crashed into the planet during the early period of Earth history led us to test the ability of iron-oxidizing bacteria to grow using iron meteorites as their source of energy. Here we report the growth of two acidophilic iron-oxidizing bacteria...

No Malabsorption of Inorganic Ferrous Iron in Patients with Achylia gastrica Celada et al. [1] recently described in this journal a considerable malabsorption of 59pe2+ for subjects with achylia gastrica. The authors have used the same test dose of 0.56 mg 59Fe2+ and the technique of whole body counting of absorbed 5βFe as proposed by us [7] but their results are in contradiction with published...

Title of dissertation: SITE-SPECIFIC INTERACTION OF DOXORUBICIN IN THE IRON RESPONSIVE ELEMENT RNA: IMPLICATIONS IN CELLULAR IRON HOMEOSTASIS AND NON-IRON DEFICIENCY ANEMIA Luigi Jhon Alvarado, Doctor of Philosophy, 2014 Dissertation directed by: Professor T. Kwaku Dayie Department of Chemistry & Biochemistry A widely utilized chemotherapy drug, doxorubicin, has recently been shown to bind to a...

In recent years the conception in biochemistry of the ionization of amphoterie electrolytes developed by Walker (1) which is still generally accepted, has been gradually losing ground. The tendency has been to replace it with the hypothesis of Bredig (2), Adams (3) and Bjerrum (4), commonly designated as the "Zwitter Ion" hypothesis. The difference between the two hypotheses is represented by t...

A significant number of chemical elements are either essential for life with known functions, or present in organisms with poorly defined functional outcomes. We do not know all the essential elements with certainty and we know even less about the functions of apparently non-essential elements. In this article, I discuss a basis for a biological periodic system of the elements and that biochemi...

Lactoferrin (LF) is a non-heme protein binding Fe3+ tightly and plays role in regulating the absorption metabolism of iron under physiological condition. The occurs duodenum. LF incorporated as functional factor food products during processing. In this review, we describe structural changes due to thermal processing food, well metabolic processes release vivo, which characterizes value matrix f...

  The aims of the present study were to determine the best time for egg stripping after ovulation and to study oocyte over-ripening in the Caspian brown trout (Salmo trutta caspius). Eggs were retained in the female abdominal cavity for 40 days post ovulation (DPO). Partial volumes of eggs stripped from 10 individually identified females at 10 days intervals and fertilized with a pool of semen ...
