Temporal compartmentation of carboxylation processes is a defining feature of crassulacean acid metabolism and involves circadian control of key metabolic and transport steps that regulate the supply and demand for carbon over a 24h cycle. Recent insights on the molecular workings of the circadian clock and its connection with environmental inputs raise new questions on the importance of light ...

The search for novel proteins is complicated by the diversity of amino acids, the non-linear relationship between amino acid sequence and folding and the huge size of sequence space. The goal of this research is to discover patterns in amino acid composition and sequence that relate to known or novel folds, thereby helping to constrain the search space for new functional proteins. This approach...

New technologies have risen into popularity causing the Liquid membrane techniques to evolve over other separation due its high selectivity and recovery, increased fluxes, reduced investment operating cost. This work focuses on extracting Methylene Blue (MB), a cationic dye using simple BLM technique from aqueous phase. It combines extraction stripping in single unit operation. The feed phase w...

Maize kernels are highly susceptible to Aspergillus spp. infection and aflatoxin (AF) contamination. Fatty acid signaling molecules appear to mediate the plant-fungal interaction by affecting the growth, development, and AF production of the fungus. In particular, fatty acid derivatives of the plant lipoxygenase (LOX) pathway are implicated in the Aspergillus spp.-seed interaction. The 9(S)-hyd...

IN THEIR BREVIA “FLUORESCENT SIGNALING in parrots” (4 Jan., p. 92), K. E. Arnold and coauthors use mate choice experiments to demonstrate that fluorescence in wild-type budgerigars (Melopsittacus undulateus) is probably functional and not incidental. However, there is further evidence to support this hypothesis in the feathers themselves. The green chest feathers of wild-type budgerigars actual...

A new VOF Type III-G.S stain was applied to histological sections of different organs and tissues of healthy and pathological larvae, juvenile and adult fish species (Solea senegalensis; Sparus aurata; Diplodus sargo; Pagrus auriga; Argyrosomus regius and Halobatrachus didactylus). In comparison to the original Gutiérrez VOF stain, more acid dyes of contrasting colours and polychromatic/metachr...
