Photoinactivation Of Buffalo Liver And Kidney Tissue Arginases And Its Kinetic Properties, Necmi̇ Özdemi̇r, Mehtap Özçeli̇k

Turkish Journal of Veterinary & Animal Sciences

Exposure of buffalo liver and kidney tissue arginases to a 150 w light source from a distance of 8-10 cm, in the presence of 0.05mM methylene blue, caused significant inhibition of arginase activity. It was determined that this inhibition occurred differently in liver and kidney tissues. Arginase activity was spectrophotometrically measured using the Thiosemicarbazide diacetyl-monoxime urea (TDMU) method. Following preincubation with MnCl_2, exposure to a 150 w light source and the addition of methylene blue, the activity of arginase was found to be lower than that after preincubation with a 150 w light source and methylene blue and the addition …

The Relationship Between Jealousy And Self-Esteem In Collegiate Athletes, Paula M. Parker Jan 2001

The Relationship Between Jealousy And Self-Esteem In Collegiate Athletes, Paula M. Parker

College of Graduate Studies: Theses & Dissertations (1964–2006)

Previous research has found contradictory results when examining the possible relationship between jealousy and self-esteem (Guerrero & Afifi, 1998, Mathes & Severa, 1981; Mikulincer, Bizman, & Aizenberg, 1989, Peretti & Pudowski, 1997; Stewart & Beatty, 1985; White, 1981). Jealousy has been most often researched in romantic relationships (Peretti & Pudowski, 1997; Salovey & Rodin, 1986) and social comparison situations (Bers & Rodin, 1984, Mikulincer, Bizman, & .Aizenberg, 1989). Few studies have examined jealousy in an athletic setting. Sport jealousy has received little attention because until recently, there was no reliable instrument to measure jealousy in sport. Pease (1987) investigated the …

Additionally, Pearson’s Correlation Coefficient was used to ascertain whether the participants’ level of knowledge was related to their actual stroke risk, as identified by the American Heart Association’s Stroke Risk Tool Descriptive analysis of the item responses revealed that the percentage of the sample correctly identifying individual signs and symptoms ranged from 44 to 77%. When actual stroke risk was …


Acute Haemolysis In Childhood Falciparum Malaria, H. Ekvall, P. Arese, F. Turrini, K. Ayi, F. Mannu, Zul Premji, A. Bjorkman Jan 2001

Acute Haemolysis In Childhood Falciparum Malaria, H. Ekvall, P. Arese, F. Turrini, K. Ayi, F. Mannu, Zul Premji, A. Bjorkman

Pathology, East Africa

Acute haemolysis associated with clinical episodes of high-level Plasmodium falciparum parasitaemia was studied in 20 children from an holoendemic area (coastal Tanzania). The change in blood haemoglobin (Hb) concentration ranged from -46 to +5 g/L during the 72-h observation period and was linearly related to maximum parasitaemia. Balance studies between loss of blood Hb, increase in plasma Hb and appearance of Hb in the urine indicated that extravascular clearance of red cells was the predominant mode of erythrocyte clearance. Most subjects, however, showed minor signs of intravascular haemolysis. The plasma Hb was ≪1% of blood Hb and haemoglobinuria was detected …


Hemoglobin Concentration In Children In A Malaria Holoendemic Area Is Determined By Cumulated Plasmodium Falciparum Parasite Densities, H. Ekvall, Zul Premji, S. Bennett, A. Bjorkman Jan 2001

Hemoglobin Concentration In Children In A Malaria Holoendemic Area Is Determined By Cumulated Plasmodium Falciparum Parasite Densities, H. Ekvall, Zul Premji, S. Bennett, A. Bjorkman

Pathology, East Africa

In malaria holoendemic areas children are anemic, but the exact influence of falciparum malaria on hemoglobin (Hb) concentration remains largely unsettled. Prospective data were therefore collected in children < 24 months of age during five months in a Tanzanian village. Children with mean asymptomatic parasitemia ≥ 400/μl had lower median Hb levels during the study than those with mean density < 400/μl. The difference was 9.7 g/L (95% confidence interval [CI] 2.8-17). In children with one or more clinical malaria episodes, the median Hb was 8.3 g/L (95% CI 0.9-16) lower than those without episode. If early treatment failure was recorded, the immediate effect on Hb was particularly important with a mean drop of 17 g/L. Interestingly, at study-end the Hb concentration represented a function of the area under the parasitemia curve (AUPC) during the previous five months, adjusting for age. In conclusion, stepwise deterioration in median Hb levels was found by asymptomatic parasitemia, clinical malaria episode, and most significantly, treatment failure.

The Pineal Gland, Via Melatonin, Protects Dna, Coordinates The Endocrine System With The Immune System And Controls The Timing Of Reproduction, Craig L. Anthony Jan 2001

The Pineal Gland, Via Melatonin, Protects Dna, Coordinates The Endocrine System With The Immune System And Controls The Timing Of Reproduction, Craig L. Anthony

Theses and Dissertations

The pineal gland secretes the hormone melatonin (n-acetyl-5-methoxytryptamine) with a circadian rhythm. This secretion's rhythm becomes disrupted with age. When melatonin secretion is decreased with advanced age, the immune, endocrine and reproductive systems fail to function optimally. Melatonin possesses lipophilic and anti-oxidant properties, providing it with access to nuclei. Melatonin protects the DNA, preventing cancerous mutation. Hippocampal degeneration and age increase and prolong the adrenocortical responses to stress. Melatonin supplementation reduces the prolonged exposure to harmful hormones.


Titrating And Evaluating Multiple Drug Regimens Within Subjects, Margaret Shih Jan 2001

Titrating And Evaluating Multiple Drug Regimens Within Subjects, Margaret Shih

Theses and Dissertations

The dosing of combination therapies is commonly undertaken empirically by practicing physicians, and there is a lack of a coherent algorithm to approach the problem of combination dosing. Current methods of evaluating multiple drug combinations in clinical trials generally do not provide information regarding the location of more effective dosages when the combination is not found to differ from the standard, even though the absence of a difference does not necessarily mean the new combination is ineffective. Additionally, if a new combination is found to be more effective, often a large proportion of the subjects has not benefited from the …


A Comparative Study Of Murine Mast Cell Progenitors, Shirley K. Desimone Jan 2001

A Comparative Study Of Murine Mast Cell Progenitors, Shirley K. Desimone

Theses and Dissertations

This thesis is a comparative study of variables affecting differentiation and proliferation of progenitor cells from various embryonic and fetal tissue sites as they differentiate into mast cells. Embryonic stem cells from gestation day 4.5 (d4.5) differentiated exclusively into mast cells when cultured in semi-solid media with stem cell factor (SCF) and Interleukin-3 (IL-3). The same was true of d8-1 1 yolk sac cells and d8-1 1 cells from the embryo itself. However, culture with SCF and IL-3 of cells from dl4 fetal livers differentiated into mast cells, cells of the erythrocyte lineage and a few "macrophages" which may have …

Influence De L'Instabilité Statique Sur La Force De Serrage Des Outils À Main Mécaniques, Denis Rancourt

Rapports de recherche scientifique

L’utilisation d’outils à main mécaniques tels les perceuses, les riveteuses, les marteaux-piqueurs etc., constituent un danger potentiel pour les travailleurs en industrie. En effet, il semble reconnu que ces outils peuvent causer différentes atteintes du système neuro-musculo-squelettique tels le syndrome des vibrations ou le syndrome du canal carpien. Malgré plusieurs études, on ne connaît pas encore très bien l’étiologie de plusieurs maladies du système neuro-musculo-squelettique et les facteurs de risques identifiés sont souvent évalués empiriquement. Une avenue potentiellement intéressante pour mieux identifier l’origine de ces maladies est d’étudier des aspects fondamentaux du contrôle moteur humain lors de la manipulation d’outils …
