A combined procedure for separating Lu, Hf, Sm, Nd, and rare earth elements (REEs) from a single sample digest is presented. The procedure consists of the following five steps: (1) sample dissolution via sodium peroxide sintering; (2) separation of the high field strength elements from the REEs and other matrix elements by a HF-free anion-exchange column procedure; (3) purification of Hf on a c...

BACKGROUND Lutzomyialongipalpis (Diptera: Psychodidae) is the major vector of Leishmania (Leishmania) infantum and thus plays a crucial role in the epidemiology of American visceral leishmaniasis (AVL). This vector is the best studied species of sand fly in the Neotropical region. Many studies claim that this vector is in fact a species complex; however there is still no consensus regarding the...

Dan Shen and Lu-Shen-Wan, traditional Chinese medicines used as remedies for heart diseases, demonstrate digoxin-like immunoreactivity. The digoxin-like immunoreactive components of Lu-Shen-Wan show approximately 55% protein binding, while Dan Shen demonstrates concentration-dependent protein binding (68% bound at lower concentrations but only 25% bound at higher concentrations). Because Dan Sh...

Geometrically constrained dioxaphospholane rings were incorporated into a bis(phosphinimine)carbazole ligand (HL) in an effort to generate an ancillary ligand system that is capable of supporting reactive lutetium alkyl functionalities and resistant to cyclometalation reactivity. This new ligand was used to prepare a lutetium dialkyl species, LLu(CH2SiMe3)2; however, the complex exhibited low t...

Comments on: variation in vernier acuity with age Li, Edwards, and Brown (2000) recently reported variation in vernier acuity with age in Vision Research. We have addressed this issue using somewhat different test displays, test conditions, and paradigms. The paper by Li et al., kindly cites a number of papers presented by our research group; here we add only related non-There seems to be a sub...

We report the construction of a versatile GFP expression plasmid and demonstrate its utility in Neurospora crassa. To visualize nuclei and microtubules, we generated carboxy-terminal fusions of sgfp to Neurospora histone H1 (hH1) and beta-tubulin (Bml). Strong expression of GFP fusion proteins was achieved with the inducible Neurospora ccg-1 promoter. Nuclear and microtubule organization and dy...
