ANHARMONIC CORRELATED EINSTEIN-MODEL DEBYE-WALLER FACTORS
An anharmonic correlated Einstein model is derived for local vibrational amplitudes in x-ray-absorption fine structure ~XAFS! that takes into account all near neighbors of absorber and backscattering…
Prevalence of asthma and asthma-like symptoms in Dalat Highlands, Vietnam.
The prevalence of asthma and asthma-like symptoms in Dalat is low and diagnosis and treatment of those afflicted with asthma appears to be suboptimal, highlighting the need for further patient education and for preventative interventions for asthma sufferers in this region.
Natural anti-HIV agents-part I: (+)-demethoxyepiexcelsin and verticillatol from Litsea verticillata.
Cytotoxic arylnaphthalene lignans from a Vietnamese acanthaceae, Justicia patentiflora.
One new norlignan and five new lignans were isolated from the leaves and stems of Justicia patentiflora by a bioassay-guided purification, and most of the new compounds display significant activity in in vitro cytotoxic assays against KB, HCT116, and MCF-7 cancer cell lines.
Antimalarial compounds from Grewia bilamellata.
Six compounds isolated from a sample of the dried leaves, twigs, and stems of Grewia bilamellata showed varying degrees of in vitro antimalarial activity against Plasmodium falciparum, but were devoid of significant cytotoxicity to the human oral epidermoid KB cancer cell line.
Further rearranged prenylxanthones and benzophenones from Garcinia bracteata
Analysis of Factors Lowering Sensitivity of Interferon-γ Release Assay for Tuberculosis
Aging, emaciation, HIV co-infection and HLA genotype affected IGRA results, and assessment of these factors might contribute to a better understanding of the assay.
New Sesquiterpenes from Litsea verticillata.
Isolates 1, 4, and 12 were found to inhibit HIV-1 replication in a green fluorescent protein (GFP)-based reporter cell line (HOG) with IC(50) values of 6.5 (27.5), 17.4 (73.1), and 28.0 (119.7) microg/mL (microM), respectively.
Anharmonic correlated Debye model Debye–Waller factors
Natural anti-HIV agents. Part IV. Anti-HIV constituents from Vatica cinerea.
The majority of the triterpenes, the sesquiterpene, 1-hydroxycyclocolorenone, and pheophorbide a showed anti-HIV activity, with the chlorophyll being the most active, and Vaticinone (1) was found to inhibit the replication of HIV-1.
