ISSN: 1432-2099Source: Springer Online Journal Archives 1860-2000Topics: BiologyPhysicsNotes: Summary Partial hepatectomy (PH) of rats (Wistar strain) resulted in acceleration of DNA synthesis in liver which reached a maximum at 36 h after PH. Whole-body radiation exposure (10 Gy) of the rats at 12 h after PH completely arrested this stimulation in DNA synthesis. The elevation of DNA synthetic rate in response to PH and complete obliteration of this stimulation by whole-body radiation exposure were found to be the reflection of levels of DNA polymerase-alpha in nuclei and nuclear matrices isolated from the rat livers. Studies based on assays of DNA polymerase in nuclei and nuclear matrices, with and without exogenous DNA template (activated calf thymus DNA), revealed that whole-body irradiation blocked induction of DNA polymerase-alpha and, in turn, assembling of DNA polymerizing apparatus. Irradiation of nuclei (suspended in buffer) in vitro at doses as high as 500 Gy did not have any inhibitory effect on DNA polymerase-alpha activitiy.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4978Keywords: thymus nuclei ; nuclear matrix ; matrix bound TdTSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Approximately 80% of the terminal deoxynucleotidyl transferase (TdT) in thymus glands from 3–4 week old rats was found to be localized in the nucleus and the remaining 20% in the cytosol. Following endogenous nuclease digestion of the thymus nuclei, 70–85% of the nuclear TdT could be removed by low salt and high salt extractions, whereas 15–30% of the enzyme remained tightly bound to the residual nuclear matrix. Low salt and high salt extracts of the nuclei contained a mixture of 58, 56, 45 and 44 kDa species of TdT whereas only 58 kDa species of the enzyme was found to be associated with the matrix. In addition to TdT, 20–25% of the nuclear DNA polymerase α was also tightly bound to the isolated nuclear matrix. These observations lead us to propose that besides being the site of DNA replicationvia-matrix bound replicational complexes [Van der Velden H.M.W. & Wanka F., Molecular Biology Reports 12 (1987): 69], nuclear matrix may also be the site of TdT mediated function and that matrix bound TdT and free TdT could be the functional and nonfunctional forms of the enzyme, respectively, in the thymus gland.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4978Keywords: thymus gland ; ATP sensitivity ; nuclear matrix ; matrix bound TdT ; free TdT ; functional TdT ; non-functional TdTSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Endogenous nuclease digestion of thymus nuclei from 3–4 week old rats followed by a step wise extraction with low salt, 0.5 M salt and 1 M salt removed approximately 70–85% of total nuclear terminal deoxynucleotidyl transferase (TdT) whereas approximately 15–30% of the enzyme remained tightly bound to the residual nuclear matrix. The cytoplasmic TdT as well as the bulk of nuclear TdT extracted in low salt and 0.5 M salt was found to be strongly inhibited at low concentration of ATP whereas matrix bound TdT and a significant portion of the enzyme in 1 M salt extract was completely insensitive to this nucleotide. The ATP resistant enzyme in the 1 M salt extract was unstable and slowly converted to ATP sensitive form upon prolonged preincubation on ice whereas under similar conditions it remained unaffected in the matrix bound form. These observations lead us to suggest that ATP resistant matrix bound TdT being capable of discriminating unnatural rNTPs against the natural dNTP substrates, may be the functionally organized form of the enzyme and that free TdT having lost the capability to distinguish between dNTP and rNTP may be the nonfunctional form of the enzyme in the thymus gland.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5117Keywords: Green biomass ; aquatic weedsSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Fractionation of aquatic green biomass of three water weeds for multiple use through yield of protein concentrate, fibrous residue and whey (deproteinised juice) has been studied. The potential of protein concentrate for use as food/feed supplement, that of fibrous residue as ensilaged fodder/substrate for mushroom growth/production of bioenergy and of whey as substrate for microbial fermentation has been studied and is discussed.Type of Medium: Electronic ResourceURL: -

SPC of high yielding species (C. juncea) was analysed for the contents of amino acids, ash, phosphorus, sugar, starch, fibre and calories, as well as forin vitro digestibility. Results indicate the promising potential ofC. juncea for SPC yield.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9104Keywords: leaf protein ; Vigna mungo ; temporal variationSource: Springer Online Journal Archives 1860-2000Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Abstract Temporal variation in total protein and soluble protein contents and protein yield ofVigna mungo leaves at intervals of every three hours during day and night was studied. The study was done with the view to ascertain the hour of harvesting the leaves for maximum yield of leaf protein concentrate. Observations reveal that the total protein and soluble protein contents in the leaves are minimum during 3.00 to 6.00 hrs, which steadily rise with time to reach the maximum values during 12.00 to 15.00 hrs, after which the same shows a steady decrease with time.Type of Medium: Electronic ResourceURL: -
