EARLIER studies in our laboratory indicated the predominance of pentose cycle In addition a correlation was demonstrated between enzymes generating reduced triphosphopyridine nucleotide and lipid synthesis (Bieber, Cheldelin & Newburgh, 1962; Baker & Newburgh, 1963). Since several of the biosynthetic pathways involve this compound, it is conceivable that in a rapidly growing system such as the ...

The complexities of the subject of food toxicants are surveyed in regard to their qualitative and quantitative aspects. Chemical and biochemical implications are reviewed, tracing the stages in the transit through the body of chemical entities in food. The capacity of the intestinal flora to bring about chemical transforma.. tions of ingested compounds may lead to detoxication or serve to creat...

Communication between cells is realized by exchange of biochemical substances. Due to internal organization of living systems and variability of external parameters, the exchange is heavily influenced by perturbations of various parameters at almost all stages of the process. Since communication is one of essential processes for functioning of living systems it is of interest to investigate con...

FMRFamide-like immunoreactivity has been previously localized to identified neurons in the CNS of the leech, Hirudo medicinalis (Kuhlman et al., 1985a). These leech antigens have been characterized biochemically by reverse-phase high-pressure liquid chromatography (HPLC) followed by radioimmunoassay (RIA). The majority of the FMRFamide-like immunoreactivity recovered by HPLC from extracts of le...

WATSON, S. J., H. AKIL AND J. M. WALKER. Anatomical and biochemical studies of the opioid peptides and related substances in the brain. PEPTIDES l: Suppl. 1, 11-20, 1980.--It is now clear that there are at least four opioid peptideneuronal systems in mammalian brain: the enkephalins, beta-endorphin and dynorphin. The focus of this presentation will be twofold--to focus on the multiple transmitt...

Abstract Tomatoes are the main vegetable crops in open and protected ground. Currently, a huge number of varieties hybrids have been created for industrial amateur growing, which differ type bush, yield, early maturity, marketability, disease resistance, color, shape, size, mechanical strength, biochemical composition fruits (content dry substances, sugars, vitamins, mineral salts, organic acid...

An increase in the chemical oxygen demand (COD) has been noticed in most Korean reservoirs. Therefore, this research systematically investigated the causes of organic accumulation. Samples of soil affecting the quality of water of reservoirs were collected at various sources and analyzed for their organic characteristics. The COD to biochemical oxygen demand (BOD) ratio was used as the key para...

the current study is focused on determination of the accumulation rate of cadmium (cd) and lead (pb) in the liver and muscle tissues of the caspian kutum fish. specimens were collected randomly from twelve stations in mazandaran province, the caspian sea basin, between october 2009 and march 2010. fork length, weight and length-weight relationship of samples were measured. one-way analysis of v...

Season-controlled changes in biochemical constituents viz. carotenoids (carotene and xanthophyll) and pectic substances along with IAA-oxidase and polyphenol oxidase (PPO) enzyme activities were estimated/assayed in leaves of Lycopersicon esculentum Mill. (tomato) in two developmental stages--pre-flowering (35 days after sowing) and post-flowering (75 days after sowing) in three different seaso...

The concept of Biological Activity Spectrum served as a basis for developing PASS (Prediction of Activity Spectra for Substances) software product. PASS predicts simultaneously more than 780 pharmacological effects and biochemical mechanisms based on the structural formula of a substance. It may be used for finding new targets (mechanisms) for known pharmaceuticals and for searching new biologi...
