Age-related changes in tissue and plasma zinc levels: Modulation by exogenously administered melatonin
(Taylor & Francis Inc, 2008)Melatonin (MEL) is synthesized mainly in the pineal gland and derived from 5-hydroxytryptophan (5-HTP). Zinc (Zn) is one of the most important trace elements in the body. Zn and MEL levels are changed with aging. The aim ... -
Extracellular polysaccharides produced by cooling water tower biofilm bacteria and their possible degradation
(Taylor & Francis Ltd, 2008)The extracellular polymers (EPS) of biofilm bacteria that can cause heat and mass transfer problems in cooling water towers in the petrochemical industry were investigated. In addition, these microorganisms were screened ... -
Unbiased estimation of the calcaneus volume using the Cavalieri principle on computed tomography images
(Elsevier Gmbh, Urban & Fischer Verlag, 2008)The size and shape of tarsal bones are especially relevant when considering some orthopedic diseases such as clubfoot. For this reason, the measurements of the tarsal bones have been the subject of many studies, none of ... -
A Biosensor Based on Bay Leaf (Laurus nobilis L.) Tissue Homogenate: Improvement of the Stability Characteristics by a Simple Bio-imprinted Technique
(Informa Healthcare, 2008)Although enzymes are effective biocatalysts that are widely used in biosensors, a major drawback that hampers many of these biotechnological applications of enzymes is their limited stability. Applications that use very ... -
A bio-imprinted urease biosensor: Improved thermal and operational stabilities
(Elsevier Science Bv, 2008)Despite the increasing number of applications of biosensors in many fields, the construction of a steady biosensor remains still challenging. The high stability of molecularly bio-imprinted enzymes for its substrate can ... -

Correlations between eye-hand reaction time and power of various muscles in badminton players
(Taylor & Francis Ltd, 2008)In the present study, the relations of simple reaction times of right and left hands with muscle powers of right and left hands, back, and leg were examined. Hand preference was assessed by the modified Edinburgh Handedness ... -
Interconversion between two unrelated protein folds in the lymphotactin native state
(Natl Acad Sciences, 2008)Proteins often have multiple functional states, which might not always be accommodated by a single fold. Lymphotactin (Ltn) adopts two distinct structures in equilibrium, one corresponding to the canonical chemokine fold ... -
Potential sources of oxidative stress that induce postexercise proteinuria in rats
(Amer Physiological Soc, 2008)Exercise-induced proteinuria is a common consequence of physical activity and is caused predominantly by alterations in renal hemodynamics. Although it has been shown that exercise-induced oxidative stress can also contribute ... -
