Biochemical composition of maturing soybean seeds and functional properties of 7S and 11S proteins
The quality and storage stability of Hack and Williams 82 soybeans at four maturation stages were studied. As compared to mature beans, trypsin inhibitor, urease and lipoxygenase (LA) activities were lower in immature seeds, but free fatty acid (FFA) was higher and oil color was greener. During …

Towards a sustainable production of Osmundea pinnatifida:: insight into the cultivation and biochemical composition of the species
… of alien species for farming purpose. The biochemical composition and variation of wild and cultivated specimens was assessed. Giving for the first time an overview of the seasonality of the biochemical and metabolomic profile of the species, an understanding of the correlation of …

An investigation of CSF dynamics and biochemical composition in normal pressure hydrocephalus utilizing the phase contrast MRI scanning
… in that order. In the second part of the study, biochemical analysis of the CSF samples collected from NPH patients was carried out. The concentration of total protein and different cations were determined in these samples (n=29) and the differences between various parameters in shunted and …

The effects of growth conditions on the elemental and biochemical composition of the diatom Thalassiosira weissflogii and the haptophyte Emiliania huxleyi
… often leads to changes of physiology and biochemical composition of microalgae. Temperature and light intensity are important environmental factors regulating the growth of microalgae. In this study, the elemental and biochemical composition were measured in 2 marine microalgae under …

CHANGES IN THE BIOCHEMICAL COMPOSITION OF TESTES DURING SPERMATOGENESIS IN ASTERIAS VULGARIS, WITH EMPHASIS ON THE ROLE OF POLYAMINES IN REGULATING PROLIFERATION
… annual spermatogenic cycle. Examination of major biochemical classes during the spermatogenic cycle provides a definition of the changing chemical microenvironment influencing germinal cells and also suggests temporal relationships among successive spermatogenic events. Testes from seastars …

Effects of restricted growth rate, elevated vitamin and mineral levels and aging on bone growth, histological integrity and biochemical composition of articular cartilage in boars
… aging on bone growth, histological lesioning and biochemical composition of articular cartilage from growing boars was examined. Growth of the radius and tibia was characterized by radiography at eight equal time points from 110 to 330 d of age. Although ad libitum-fed boars had larger bones in …

Genetic effects of prolonged UV-B exposure in a Namaqualand daisy - Dimorphotheca sinuata
… was found to have a major effect on the biochemical composition of the chloroplast accompanied by impairment of photosynthetic function, involving a down-regulation of photosynthetic genes and an up-regulation of flavonoid biosynthesis.

QUALITATIVE ANALYSIS OF LIPOPROTEINS AND STUDY OF THE METABOLIC PROFILE IN DIFFERENT CLINICAL SETTINGS BY RAMAN SPECTROSCOPY
… able to offer a rapid specific overview of the biochemical composition of the analyzed sample without any preparation or labeling. This non-invasive technique is based on the radiation/matter interaction where a sample is illuminated by a laser which interacts with the vibrational motions of the …

Raman spectroscopy as a tool for studying bacterial cell compounds
… spectra also contain valid information about biochemical composition of the cells. Because bacterial Raman spectra are the sum of signals from all Raman active cell compounds, they are complex. Although in literature some bands have been assigned to (specific or groups of) biomolecules, only …

Development of a pre-selection index for cider apple (Malus x domestica Borkh.) genotypes by phenotyping a low-chill requiring red-fleshed breeding progeny
… promising genotypes. The sensory attributes and biochemical composition of this unique low-chill, red-fleshed progeny were also analysed. The indexing results suggested that sweet cider production is the most viable outcome, as most top-performing genotypes were classified as sweet cider apples, …

Comparison of Two Separation Methods for Biological Particles: Field-Flow Fractionation (FFF) and Sucrose Density Gradients
… clean fractions were further analyzed for their biochemical composition (using radiolabeling and subsequent biochemical fractionation) revealing significant differences in the bulk biochemical makeup between prokaryotic and eukaryotic microbes. Even within domains, the sucrose gradient method was …

Heterotrophic production of the microalgae Cyclotella cryptica: feed for aquaculture.
… biomass depends on several physiological and biochemical attributes including microalgal cell size and shape, digestibility, non-toxicity and biochemical composition. The growth rate and biochemical composition of microalgal biomass can be influenced by culture and environmental conditions. …

Development of a suitable diet for endangered juvenile oyster mussels, Epioblasma capsaeformis (Bivalvia:Unionidae), reared in a captive environment
… Clinch River and sacrificed for gut content and biochemical composition analyses in summer. Feces and pseudofeces from live river-collected juveniles were examined seasonally for algae, detritus, and bacteria to qualitatively determine diet of specimens. Two feeding trials also were conducted in …
