Bra j IE, a major allergen from oriental-mustard (Brassica juncea) seeds, has been isolated and characterized. Its primary structure has been elucidated. This protein is composed of two chains (37 and 92 amino acids) linked by disulphide bridges. The amino acid sequence obtained is closely related to that previously determined for Sin a I, an allergen isolated from yellow mustard (Sinapis alba)...

Details of the sequential morphological changes occurring during yeastlike to mycelial-form conversion of the dimorphic pathogen Paracoccidioides brasiliensis are described and illustrated by photomicrographs. Conversion of yeastlike to hyphal morphology was initiated by changing the temperature of incubation from 37 to 23 C. Production by the parent yeastlike cells of elongated buds developing...

The dye sunset yellow (SY) forms columnar aggregates via pi-pi stacking in aqueous solutions. These aggregates develop orientational and translational order at elevated concentrations to exhibit the nematic (N) and columnar (C) mesophases. Positional-order correlation lengths of the aggregates in the directions parallel and perpendicular to the stacking direction were measured as functions of t...

An in-house method was used, including dissociation of Somatomedin C/insulin-like Growth Factor I (Sm-C/IGF-I) binding proteins with acid and extraction of Sm-C/IGF-I by C-2 cartridge before radioimmunoassay, to measure plasma Sm-C/IGF-I levels in three groups of patients--total of 19--with acromegaly who underwent transsphenoidal removal of pituitary tumors. In group A (n = 7), the Sm-C/IGF-I ...

The free amino acid concentrations in cotyledons and axes of soybean (Glycine max [L.] Merr. cv. Wells) seedlings were determined by automated single column analysis after germination at 10 and 23 C. After 5 days germination at 10 C, glutamate and aspartate were in high concentration in both cotyledons and axes (38 and 24% of total free amino acids recovered, respectively), whereas the concentr...

background: nail disorders comprise approximately 10% of all dermatological conditions. abnormalities in the color of nails are called ungal dyschromia or chromonychia. ungual dyschromia may be endogenous or exogenous. yellow discoloration of the nails has been reported during the last years as separate observation related to drug administration, during hemodialysis and associated with pulmonar...

nanosilver of nanometer-sized silver (ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. boric acid (h3bo3) is water soluble (ph=7). boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the acc synthase and acc oxidase delays senescence of flower. in this study of different concentrations of boric acid and nano-silver was eva...

The response and behavior of bamboo green, timber, and yellow of moso bamboo (Phyllostachys heterocycla) to three pretreatments, sulfite (SPORL), dilute acid (DA), and alkali (NaOH), were investigated and compared with varied chemical loadings at 180°C for 30 min with a 6.25:1 (v/w) liquor-to-bamboo ratio. All the pretreatments improved the enzymatic digestibility of bamboo substrates. Under th...
