sclerotinia sclerotiorum is a phytopathogenicfungus that attacks more than 400 plant species of them medicinal plant. in this study the extract obtained from basal stalk rot of helianthus annuus l., attacked by s. sclerotiorum, was subjected to the analysis of ftir to identify the presence of beta-glucan. ft-ir spectrum showed four ranges of bands in 890 cm-1, two overlap band in 1047 and 1078 ...

background and objectives: beta-thalassemia continues to be a cause of significant burden to the society particularly in the poorer developing countries. although sophisticated methods of screening have become available, a hunt for a cheap, rapid, objective screening method still remains elusive. thus, the objectives are to study the validity of naked-eye-single-tube-osmotic-fragility-test (nes...

conclusions light and temperature were both relevant factors that contributed to the growth and beta-carotene accumulation of the three d. salina strains, and nahco3 had significantly positive effects on growth. the degree of impact of the different factors on cell growth was temperature > nahco3 > light intensity > kno3 > co (nh2)2 > strains; the impact on beta-carotene accumulation was temper...

The distribution of beta-adrenergic receptors in sections of the human right and left coronary arteries and of the anterior intraventricular branch was studied by the use of combined in vitro radioreceptor binding and autoradiographic techniques. [125I]Cyanopindolol was used as a ligand for beta-adrenergic receptors. Binding of the radioligand to sections of the three coronary arteries under st...

Oxidative modification of low density lipoprotein (LDL) generates a form that is degraded much more rapidly by macrophages and may thus be more atherogenic than unoxidized LDL. Recently, we provided evidence that oxidative modification of LDL may play a significant role in the generation of fatty streaks in the LDL receptor-deficient rabbit. The major lipoprotein in cholesterol-fed animals is t...

The ABri is a 34 residue peptide that is the major component of amyloid deposits in familial British dementia. In the amyloid deposits, the ABri peptide adopts aggregated beta-pleated sheet structures, similar to those formed by the Abeta peptide of Alzheimer's disease and other amyloid forming proteins. As a first step toward elucidating the molecular mechanisms of the beta-amyloidosis, we exp...

This study was designed to investigate the ability of bronchoalveolar and blood mononuclear cells to produce inflammatory mediators in vitro in pulmonary sarcoidosis. Seventeen patients with pulmonary sarcoidosis (stage I n = 8; stage II/III n = 9) and 10 normal controls were investigated. Bronchoalveolar and peripheral blood mononuclear cells were cultured in serum-free medium, without stimula...

background: hb a2 is elevated in subjects with beta thalassemia minor but small percent of carriers have normal hb a2 with elevated levels of hbf (2-10%). this type of thalassemia is called delta beta thalassemia, and can be missed in pre-marriage hematologic consults or screening which leads to increased risk of child birth with beta thalassemia major. materials and methods: in this prospectiv...
