This study examined the effects of long-term frozen storage (-20 °C for 5 months) of free amino acids (FAAs) and nucleotide-related compounds (NRCs) in muscle and hepatopancreas of the coconut crab Birgus latro. Although long-term frozen storage had little effect on FAA composition in muscle, the amounts of several FAAs increased in the hepatopancreas that may be the result of protein decomposi...

A novel compound, KS-505a was isolated from the culture broth of a strain identified as Streptomyces argenteolus A-2. The compound inhibited bovine brain Ca2+ and calmodulin-dependent cyclic-nucleotide phosphodiesterase with an IC50 value (the concentration causing 50% inhibition) of 0.065 microM. The compound around that concentration had little or no effect on heart calmodulin-dependent and -...

Nisin is a green, safe and natural food preservative. With the expansion of nisin application, demand for has gradually increased, which equates to increased requirements production. In this study, Lactococcus lactis subsp. lxl was used as original strain, compound mutation method applied induce mutations. A high-yielding genetically stable strain (Lactobacillus A32) identified, with titre rais...

We have developed a new red fluorogenic compound derived from naphthorhodamine for a reduction-triggered fluorescence probe to sense oligonucleotides. The fluorogenic reaction between naphthorhodamine azide derivatives and reducing reagents such as triphenylphosphine (TPP) on the DNA target does not use any enzyme or reagent, and fluoresces at 650 nm. The probes were used for dual color detecti...

background microsatellites have evoked the interest of researchers owing to their applications in different fields such as dna fingerprinting, genetic mapping, population genetics, forensics, paternity studies and evolution. objectives the present study focused on the analysis of simple sequence repeats (ssrs) in genomes of seven species from three genera of the filoviridae family. materials an...

Hedyotis hamiguitanensis, from Mt. Hamiguitan, Davao Oriental, Philippines, is described, illustrated, and compared with two similar species, H. whiteheadii schlechteri. This species distinguished congeneric Philippine by its 5–12 cm long, compound, umbellate inflorescences, pendulous flowers, lanceolate to oblanceolate, thick, scabrid leaf blades revolute margins. Its phylogenetic systematic p...
