The highly virulent GDVII strain of Theiler's murine encephalomyelitis virus causes acute and fatal encephalomyelitis, whereas the DA strain causes mild encephalomyelitis followed by a chronic inflammatory demyelinating disease with virus persistence. The differences in the amino acid sequences of the leader protein (L) of the DA and GDVII strains are greater than those for any other viral prot...

Background and objectives: Leishmaniasis is caused by the genus of Leishmania and is one of the important health problems worldwide. Serious side effects, the lack of effective vaccines and the emergence of drug resistance are the major weak points of leishmaniasis treatment. The purpose of this study was to evaluate leishmanicidal effects of Allium giganteum ...

The pharmacological properties of glutamate agonists were compared in astrocyte-rich and astrocyte-poor cultures derived from embryonic rat cerebral cortex. The object of this investigation was to determine the extent to which glutamate uptake might influence the receptor-mediated neurotoxic actions of these compounds. In astrocyte-rich cultures, using 30 min exposures, we observed that the pot...

The Cucurbitaceae genus Austrobryonia, with four species endemic to Australia, is described, illustrated, and placed in a phylogenetic context based on molecular and morphological data. In the Flora of Australia (Telford 1982), all four species were provisionally included in Mukia, but not formally described. Austrobryonia argillicola, A. centralis, A. micrantha, and A. pilbarensis are adapted ...

The synthesis of a proline-rich cyclic heptapeptide, fanlizhicyclopeptide A (8), previouslyisolated from the fruits of Annona squamosa (sugar-apples), is described via coupling oftetrapeptide l-prolyl-l-tyrosyl-l-leucyl-l-proline methyl ester with tripeptide Boc-glycyl-lvalyl-l-proline followed by cyclization of the linear fragment having seven amino acid units.Structure of the synthesized cycl...

BACKGROUND For the treatment of the bisphosphonates and other drugs related osteonecrosis of the jaws, currently medication-related osteonecrosis of the jaws (MRONJ), have been established different conservative therapeutic approaches, avoiding surgery except in cases of extreme need. Given the controversy and lack of current consensus regarding MRONJ therapy in patients, new techniques have be...
