Cell death and degeneration in the symbiotic dinoflagellates of the coral Stylophora pistillata during bleaching

Rising sea temperatures are increasing the incidences of mass coral bleaching (the dissociation of the coral-algal symbiosis) and coral mortality. In this study, the effects of bleaching (induced by elevated light and temperature) on the condition of symbiotic dinoflagellates (Symbiodinium sp.) within the tissue of the hard coral Stylophora pistillata (Esper) were assessed using a suite of techniques. Bleaching of S. pistillata was accompanied by declines in the maximum potential quantum yield of photosynthesis (F-v/F-m, measured using pulse amplitude modulated [PAM] fluorometry), an increase in the number of Sytox-green-stained algae (indicating compromised algal membrane integrity and cell death), an increase in 2',7'-dichlorodihydrofluroscein diacetate (H(2)DCFDA)stained algae (indicating increased oxidative stress), as well as ultrastructural changes (vacuolisation, losses of chlorophyll, and an increase in accumulation bodies). Algae expelled from S. pistillata exhibited a complete disorganisation of cellular contents; expelled cells contained only amorphous material. In situ samples taken during a natural mass coral bleaching event on the Great Barrier Reef in February 2002 also revealed a high number of Sytox-labelled algae cells in symbio. Dinoflagellate degeneration during bleaching seems to be similar to the changes resulting from senescence-phase cell death in cultured algae. These data support a role for oxidative stress in the mechanism of coral bleaching and highlight the importance of algal degeneration during the bleaching of a reef coral.

Young children's understanding of death

There is a long history of research on children's understanding of death. This article briefly reviews psychoanalytic and Piagetian literature on children's death concepts, then focuses on recent research in developmental psychology that examines children's understanding of death in the context of their developing folk theory of biology. This new research demonstrates that children first conceptualise death as a biological event around age 5 or 6 years, at the same time that they begin to construct a biological model of how the human body functions to maintain life. This detailed new account of children's developing biological knowledge has implications for practitioners who may be called on to communicate about death with young children.

The importance of Na(plus)-K(plus)-Cl- cotransport in nitrogen mustard induced cell death

The incubation of murine leukaemic L1210 cells in vitro for 4 hours (hr) with 10uM nitrogen mustard (HN2), a bifunctional alkylating agent, inhibited the influx of the potassium congener, 88rubidium+ ( 86Rb+) by the selective inhibition of the Na+-K+-CI- cotransporter. The aim of this project was to investigate the importance of this lesion in HN2-induced cytotoxicity. 86Rb+ uptake in human erythrocytes was inhibited by high concentrations of HN2 (2mM) and occurred in two phases.In the first hour both the Na+/K+ ATPase pump and the Na+-K+-CI- cotransporter were equally inhibited but after 2 hrs exposure to 2mM HN2, the Na+ -K+ -CI- cotransporter was significantly more inhibited than the Na+/K+ ATPase pump. In contrast, both potassium transport systems were equally inhibited in L1210 cells incubated for 10 minutes with 1mM HN2. The selective inhibition of the Na+-K+-CI- cotransporter, after a 3 hrs exposure to 10uM HN2, was not absolved by coincubation with 5ug/ml cycloheximide (CHX), an inhibitor of protein synthesis. Incubation of L1210 cells with concentrations of diuretics which completely inhibited Na+-K+-CI- cotransport did not enhance the cytotoxicity of either HN2 or its monofunctional analogue 2-chloroethyldimethylamine (Me-HN1). The incubation of L1210 cells with a twice strength Rosewell Park Memorial Institute 1640 media did not enhance the toxicity of HN2. An L1210 cell line (L1210FR) was prepared which was able to grow in toxic concentrations of furosemide and exhibited a similiar sensitivity to HN2 as parental L1210 cells. Treatment of L1210 cells with 10uM HN2 resulted in a decrease in cell volume which was concurrent with the inhibition of the Na+-K+-CI- cotransporter. This was not observed in L1210 cells treated with either 1 or O.SuM HN2. Thus, possible differences in the cell death, in terms of necrosis and apoptosis, induced by the different concentrations of HN2 was investigated. The cell cycle of L1210 cells appeared to be blocked non-specifically by 10uM HN2 and in S and G2/M by either 1 or 0.5uM HN2. There were no significant changes in the cytosolic calcium concentrations of L1210 cells for up to 48 hrs after exposure to the three concentrations of HN2. No protection against th_ toxic effects of HN2 was observed in L1210 cells incubated with 5ug/ml CHX for up to 6 hrs. Incubation for 12 or 18 hrs with a non-toxic concentration (5mM) of L-Azetidine-2- carboxylic acid (ACA) enhanced the toxicity of low concentrations (<0.5uM) of HN2.

Activation of ERK1/2, JNK and PKB by hydrogen peroxide in human SH-SY5Y neuroblastoma cells:role of ERK1/2 in H2O2-induced cell death

Reactive oxygen species including H2O2 activate an array of intracellular signalling cascades that are closely associated with cell death and cell survival pathways. The human neuroblastoma SH-SY5Y cell line is widely used as model cell system for studying neuronal cell death induced by oxidative stress. However, at present very little is known about the signalling pathways activated by H2O2 in SH-SY5Y cells. Therefore, in this study we have investigated the effect of H2(O2 on extracellular signal-regulated kinase 1/2 (ERK1/2), c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (p38 MAPK) and protein kinase B (PKB) activation in undifferentiated and differentiated SH-SY5Y cells. H2O2 stimulated time and concentration increases in ERK1/2, JNK and PKB phosphorylation in undifferentiated and differentiated SH-SY5Y cells. No increases in p38 MAPK phosphorylation were observed following H2O2 treatment. The phosphatidylinositol 3-kinase (PI-3K) inhibitors wortmannin and LY 294002 ((2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one) inhibited H2O2-induced increases in ERK1/2 and PKB phosphorylation. Furthermore, H2O2-mediated increases in ERK1/2 activation were sensitive to the MAPK kinase 1 (MEK1) inhibitor PD 98059 (2'-amino-3'-methoxyflavone), whereas JNK responses were blocked by the JNK inhibitor SP 600125 (anthra[1-9-cd]pyrazol-6(2H)-one). Treatment of SH-SY5Y cells with H2O2 (1 mM; 16 h) significantly increased the release of lactate dehydrogenase (LDH) into the culture medium indicative of a decrease in cell viability. Pre-treatment with wortmannin, SP 600125 or SB 203580 (4-(4-fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)1H-imidazole; p38 MAPK inhibitor) had no effect on H2O2-induced LDH release from undifferentiated or differentiated SH-SY5Y cells. In contrast, PD 98059 and LY 294002 significantly decreased H2O2-induced cell death in both undifferentiated and differentiated SH-SY5Y cells. In conclusion, we have shown that H2O2 stimulates robust increases in ERK1/2, JNK and PKB in undifferentiated and differentiated SH-SY5Y cells. Furthermore, the data presented clearly suggest that inhibition of the ERK1/2 pathway protects SH-SY5Y cells from H2O2-induced cell death.

Microarray analysis of expression of cell death-associated genes in spinal cord cells with cyclic tensile strain

Previous studies have described alterations in gene expression following spinal cord injury, but this response to mechanical stimuli is difficult to investigate in vivo. Therefore, we have investigated the effect of cyclic tensile strain on cultured spinal cord cells from E15 Sprague-Dawley rats. Microarray analysis of gene expression and categorization of identified genes were performed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) systems. The application of cyclic tensile strain reduced the viability of cultured spinal cord cells significantly in a dose- and time-dependent manner. GO analysis identified candidate genes related to apoptosis (44) and to response to stimulus (17). KEGG analysis identified changes in the expression levels of 12 genes of the mitogen-activated protein kinase (MAPK) signaling pathway, which were confirmed to be upregulated and validated by RT-PCR analysis. Spinal cord cells undergo cell death in response to cyclic tensile strain, which were dose- and time-dependent, with upregulation of various genes, in particular of the MAPK pathway.

Focusing on the area of tourism she introduces value – experience connections, the differences and accordance among approaches of the experts, and the changes of the content of interpretations from time to time. The author set several targets with her work: introducing the diversity of consumer value approaches in tourism; proving the lack of the precisely and scientifically composed concept of consumer value; and based on former empirical researches summarizing the potential consumer value dimensions in tourism.

Understanding Suicidal Behavior Among Latin Adolescent Girls Living in the United States

Suicide in adolescents between the age of 10 and 24 years old is the second cause of death in the United States. This rate differentiates by ethnic and racial groups within the same country; Latino/Hispanic adolescent girls have the highest rate of suicide behavior. Considering that Latino/Hispanic is the fastest growing minority group in the nation, with an expected population of 30% by 2060, this issue should be a public health priority. This paper answers the following question: what are the conditions operating among Latin adolescent girls living in the United States that cause significantly higher suicidal behavior rates in the U.S. and compared with their peers in Latin American countries? And, how adequate are treatments such as Dialectical Behavioral Therapy and prevention programs in tackling the specific risk factors affecting this population? The paper is divided into five chapters; the first four are based on a comprehensive literature review of statistics of suicide, risk and protective factors, treatment, and prevention programs. The last chapter offers an analysis of the sociological phenomenon of suicidal behavior in this population and three brief narratives of attempters and non-attempters. Studies show that subjective distress, familism and immigration issues are the key risk factors of suicidal behavior in Latina adolescent girls. Understanding the risk factors is key in order to design promotion and prevention programs that are culturally relevant and that can have a positive impact in the reduction of this alarming phenomenon.

On the Threshold of Paradise and Present: Memory in Contemporary Cuban – American Literature

The exile leaving his or her homeland for new and unknown territory travels with much more than just luggage and the clothes on his or her back. He or she carries a weighty collection of memories. Available for the exile in times when the harmony of the past is far removed from the difficult circumstances present during the process of cultural assimilation, these memories present an opportunity for the exile to fashion for him or herself an identity that mimics the realities of life in the home left behind. In this creative endeavor, I seek to examine the powerful potential of memory as it is exercised by a collection of Cubans and Cuban-Americans in different corners of the United States. Analyzing Achy Obejas’ Memory Mambo, Cristina García’s Dreaming in Cuban, Ana Menéndez’s In Cuba I Was a German Shepherd, and Elías Miguel Muñoz’s Brand New Memory, I aim to trace the suggestive potential of memory as it is used by each of the characters in these works in an effort to reconcile their Cuban identities with the ones that are in the process of creation in the U.S. I will borrow from a collection of literature dealing with identity and exile, relevant graduate-level theses on Cuban-American literature, as well as theoretical perspectives on memory formation and nostalgia in order to trace the various ways in which memory is relied on in the process of cultural assimilation and emotional coping. Being presented in Miami, which hosts the largest concentration of Cuban immigrants, this thesis aims to present itself as a reflective tool for Cubans and Cuban-Americans who may find value in seeing their personal sentiments portrayed in literature, thus allowing for a potential reevaluation of identity. If the existing literature on my topic of analysis reveals anything, it is that the scope of my project is one that has not been inspected previously, thus making my analytical contribution a new one that will add a new interpretive set of lens through which readers of contemporary Cuban-American literature can examine the works.
