13. Maturation and conservation of murcott tangor (Citrus reticulata Blanco x C. sinensis Osbeck) and tahiti lime (Citrus latifolia Tanaka) under bioregulators action. / Maturação e conservação do Tangor Murcote (Citrus reticulata Blanco x C. sinensis Osbeck) e da lima ácida Tahiti (Citrus latifolia Tanaka) sob efeito de biorreguladores.
The experiments were conducted from August 2001 to August 2002 in the post-harvest Physiology Laboratory, Department of Biology, ESALQ-USP. It was checked the isolated effect of gibberellic acid, 1-methylcyclopropene and aminoethoxyvinilglycine, and also the combinations of 1-MCP with GA3 and AVG with GA3, on Murcott tangor and Tahiti lime post-harve

14. Mycobacterium bovis BCG but not Mycobacterium leprae induces TNF-alpha secretion in human monocytic THP-1 cells
In this study, we compared the level of TNF-alpha secretion induced in monocytic THP-1 cells after phagocytosis of Mycobacterium leprae, the causative agent of leprosy, and M. bovis BCG, an attenuated strain used as a vaccine against leprosy and tuberculosis. The presence of M. leprae and BCG was observed in more than 80% of the cells after 24 h of exposure.

15. PHYSIOLOGY OF THE SPORULATION PROCESS IN CLOSTRIDIUM BOTULINUM II. : Maturation of Forespores1
Day, Lawrence E., (Michigan State University, East Lansing) and Ralph N. Costilow. Physiology of the sporulation process in Clostridium botulinum. II. Maturation of forespores. J. Bacteriol. 88:695–701. 1964.—Clostridium botulinum, strain 62-A, did not sporulate endotrophically, but forespores matured to refractile, heat-resistant spores when replaced in

16. Pseudomonas aeruginosa Displays Multiple Phenotypes during Development as a Biofilm
Complementary approaches were employed to characterize transitional episodes in Pseudomonas aeruginosa biofilm development using direct observation and whole-cell protein analysis. Microscopy and in situ reporter gene analysis were used to directly observe changes in biofilm physiology and to act as signposts to standardize protein collection for two-dimensi

17. B-Cell Maturation Protein, Which Binds the Tumor Necrosis Factor Family Members BAFF and APRIL, Is Dispensable for Humoral Immune Responses
B-cell maturation protein (BCMA) is a member of the tumor necrosis factor (TNF) receptor family and is expressed in B lymphocytes. BCMA binds two TNF family members, BAFF and APRIL, that stimulate cellular proliferation. BAFF in particular has been shown to influence B-cell survival and activation, and transgenic mice overexpressing BAFF have a lupus-like au

18. The endogenous retroviral locus ERVWE1 is a bona fide gene involved in hominoid placental physiology
The definitive demonstration of a role for a recently acquired gene is a difficult task, requiring exhaustive genetic investigations and functional analysis. The situation is indeed much more complicated when facing multicopy gene families, because most or portions of the gene are conserved among the hundred copies of the family. This is the case for the ERV

19. Expression of a conserved cell-type-specific protein in nerve terminals coincides with synaptogenesis.
Contact of axons with target territories results in the formation of synapses, specific junctional complexes that may represent a final stage of neuronal maturation. Synaptosomal-associated protein 25 (SNAP-25) is a component of particular nerve terminals recently identified in rodent brain. To evaluate the structure and regulation of molecular components of

20. Developmental Physiology of Cluster-Root Carboxylate Synthesis and Exudation in Harsh Hakea. Expression of Phosphoenolpyruvate Carboxylase and the Alternative Oxidase1
Harsh hakea (Hakea prostrata R.Br.) is a member of the Proteaceae family, which is highly represented on the extremely nutrient-impoverished soils in southwest Australia. When phosphorus is limiting, harsh hakea develops proteoid or cluster roots that release carboxylates that mobilize sparingly soluble phosphate in the rhizosphere. To investigate the physio

21. Juvenile hormone, reproduction, and worker behavior in the neotropical social wasp Polistes canadensis
Previous studies of the division of labor in colonies of eusocial Hymenoptera (wasps and bees) have led to two hypotheses regarding the evolution of juvenile hormone (JH) involvement. The novel- or single-function hypothesis proposes that the role of JH has changed from an exclusively reproductive function in primitively eusocial species (those lacking morph

22. How partially inhibitory concentrations of chloramphenicol affect the growth of Escherichia coli.
In the presence of up to 6 microM chloramphenicol, balanced exponential growth of Escherichia coli occurred at a reduced rate after an adjustment period. The inhibition of ribosome function by chloramphenicol within growing cells was inferred from measurements of growth rate and cell composition during balanced growth and of pulse-labeling of cells by radioa

23. Obesity and hyperleptinemia in metallothionein (-I and -II) null mice
Metallothionein (MT) has several putative roles in metal detoxification, in Zn and Cu homeostasis, in scavenging free radicals, and in the acute phase response. Mice of mixed 129/Ola and C57BL/6J background with targeted disruption of MT-I and MT-II genes are more sensitive to toxic metals and oxidative stress. We noted that these animals were larger than mo

24. The Role of Light and Growth Regulators in the Opening of the Dentaria Petiolar Hook
The phenomenon of the etiolated hook is not restricted to the hypocotyl of the dicotyledenous plant (e.g., Phaseolus) but appears to serve a similar, adaptive function in the petioles of certain rhizomatous plants. The commonly employed regulants of hypocotyl hook opening were tested for their effect on the petiolar hook of Dentaria diphylla. The hook was fo
