    Description: We searched the published literature for data on the density-dependence of seaweed growth under different nutrient levels. The search was based on the Web of Science®, accessed in May 2019, using a combination of keywords including "seaweed & remediation", "seaweed & bioremediation", "seaweed & nitrogen removal" and "seaweed & phosphorous removal". These searches yielded a total of 164 papers reporting growth rates and biomass density for seaweed. We retrieved the growth rates, biomass density, concentration of the dominant forms of inorganic nutrients - ammonia, nitrate and phosphate - and incident irradiance, and recorded the taxa (chlorophyta, phaeophyta or rhodophyta). This generated a raw dataset containing a total of 1729 experimental assessments. For all the assessments, we further converted all growth rates to units of % day-1 and biomass density (i.e. the seaweed biomass per unit habitat volume) to g FW L-1.

    Changes in Lipogenic Capacity and Activities of Ketolytic and Lipogenic Enzymes in Brain Regions of Developing Rats (1983)

    Notes: Abstract: Oxidation of ketone bodies (KBs) generates acetyl coenzyme A (AcCoA), which can be further incorporated into fatty acid. We have determined the rates of lipogenesis from ketone bodies in developing rats and their relation to the activities of enzymes involved in the production of cytoplasmic AcCoA via different pathways in brain regions. In the cerebrum (Cbr), rates of fatty acid synthesis from [3-14C]acetoacetate ([3-14C]AcAc) were high during the early postnatal period but decreased rapidly thereafter until weaning. Although similar developmental patterns of synthesis characterized the cerebellum (Cbl), midbrain (Mb), brain stem (Bs), and thalamus (Th), maximal rates were highest in the Cbr and lowest in the Th. In all regions, synthetic rates were higher throughout the entire suckling period than in adulthood. There were no appreciable differences in synthetic rates among brain regions of adult rats. The developmental changes in rates of AcAc incorporation into fatty acids were closely related to AcAcCoA synthetase activity, but not to activities of ATP-citrate lyase or AcCoA synthetase. During the early postnatal stage the enhanced rates of lipogenesis were accompanied by increased activities of AcAcCoA synthetase in all regions, with the highest activity occurring in the Cbr. The sequence of reactions coupling AcAcCoA synthetase and AcAcCoA thiolase in cytoplasm may be an important pathway for generation of AcCoA from KBs for fatty acid synthesis in all regions of the developing brain. This interpretation is strengthened by evidence of concomitant increases in the activities of fatty acid synthetase and AcCoA carboxylase.

    Increased expression of lung resistance-related protein in lower grade urothelial carcinoma of the renal pelvis and ureter (2004)

    Notes: Abstract Background: Lung resistance-related protein (LRP), like multidrug resistance gene 1 (MDR1) and multidrug resistance-associated proteins (MRP), has been associated with intrinsic therapeutic resistance in various malignancies. To date, there has been no study on the expression of LRP in urothelial carcinomas of the renal pelvis and ureter. We investigated the protein and mRNA expression levels of LRP, MDR1 and MRP1 in this malignancy and the clinical significance of their expression was evaluated.Methods: Forty urothelial carcinomas of the renal pelvis and ureter and 31 normal upper urothelial samples were examined by immunohistochemistry and reverse transcription polymerase chain reaction to determine the protein and mRNA levels of the multidrug resistance-related genes, respectively.Results: The positive staining rates and mRNA levels of LRP were the highest among these multidrug resistance-related genes in both normal urothelium and carcinoma examinations. In contrast to the up-regulated expression of MDR1, the expression of LRP tended to be down-regulated in carcinomas. Moreover, the expression of LRP inversely correlated with tumor grades, but this correlation was not found for the other two genes. However, there was no correlation among the expression of the three genes observed.Conclusion: Lung resistance-related protein was strongly expressed in urothelial carcinomas of the renal pelvis and ureter, particularly in well-differentiated carcinomas.

    Genome-wide expression analysis of iron regulation in Burkholderia pseudomallei and Burkholderia mallei using DNA microarrays (2005)

    Notes: Burkholderia pseudomallei and B. mallei are the causative agents of melioidosis and glanders, respectively. As iron regulation of gene expression is common in bacteria, in the present studies, we have used microarray analysis to examine the effects of growth in different iron concentrations on the regulation of gene expression in B. pseudomallei and B. mallei. Gene expression profiles for these two bacterial species were similar under high and low iron growth conditions irrespective of growth phase. Growth in low iron led to reduced expression of genes encoding most respiratory metabolic systems and proteins of putative function, such as NADH-dehydrogenases, cytochrome oxidases, and ATP-synthases. In contrast, genes encoding siderophore-mediated iron transport, heme-hemin receptors, and a variety of metabolic enzymes for alternative metabolism were induced under low iron conditions. The overall gene expression profiles suggest that B. pseudomallei and B. mallei are able to adapt to the iron-restricted conditions in the host environment by up-regulating an iron-acquisition system and by using alternative metabolic pathways for energy production. The observations relative to the induction of specific metabolic enzymes during bacterial growth under low iron conditions warrants further experimentation.

    Structure and regulation of the fushi tarazu gene from Drosophila hydei (1995)

    Notes: Abstract The Drosophila melanogaster segmentation gene fushi tarazu (ftz) encodes a homeodomain-type transcription factor involved in the control of larval pattern formation. Loss of function mutations cause an embryonic lethal, pair-rule phenotype. The segmentation defects, but not the lethality, can be partially rescued by the ftz orthologue from Drosophila hydei. In this work, the primary structure, expression and regulation of the D. hydei ftz gene was characterized. Sequence comparisons classify ftz as a rather fast evolving gene. However, since the homeodomain of the D. hydei FTZ protein is highly similar to that of D. melanogaster, proper regulation of D. melanogaster ftz downstream genes would be expected. In D. melanogaster embryos, a D. hydei ftz transgene is expressed normally, independent of endogenous ftz gene activity, suggesting that D. hydei ftz regulatory sequences are correctly recognized by D. melanogaster transcription factors. Accordingly, lacZ fusion constructs driven by the D. hydei ftz upstream element are expressed normally in D. melanogaster embryos. Altogether, the similarities between the two ftz orthologues by far outweigh the differences. The limited success of the trans-species rescue might be, therefore, a consequence of the accumulation of too many subtle changes in gene function, exceeding the limits of developmental plasticity during fly embryogenesis.
