I HE RAPID RESPONSE of the blood cells to an adverse situation in the body is not only dependent on the ready reservoirs of such cells but also on the cell proliferation of the hemopoietic tissues. Changes in cellular proliferation are likely to be accompanied by changes in protein synthesis and total protein in individual cells. Like marrow cells, tumor cells also have a high rate of cell prol...

Collagen content and cross-linking are believed to be major determinants of tendon structural integrity and function. Sex and chronic resistance training have been shown to alter tendon function and may also alter the key structural features of tendon. Patellar tendon biopsies were taken from untrained men [n = 8, 1 repetition maximum (RM) = 53 +/- 3 kg], untrained women (n = 8, 1 RM = 29 +/- 2...

we studied the role of nutrients on various aspects of the periphyton community in artificialstreams. dry mass, ash-free dry mass, chlorophyll a and biovolume of the periphyton community weremeasured under 3 different nutrient regimes, including one from natural streams as a control and twowhich were enriched with n and n+p. results of this experiment indicate that the standing crop of theperip...

The boron contents of 68 edible common macrofungi of Hungary were analysed. The average boron content of the examples was 11.74 mg/kg dry mass, this is higher than the average value of green plants of Hungary (7.4 mg/kg dry mass). Although the highest boron contents were found in the examples from woods near Budapest, the differences between the various sites are not significant. It seems that ...

In this paper, the phenolics content and the antioxidant activity of the ethanol extracts prepared from the leaves of Globularia alypum L were evaluated. These extracts were obtained by two different extraction methods. The composition of polyphenols (198±0.52μg gallic acid equivalent/mg of dry mass) and tannins (30.65±0.11μg tannic acid equivalent/mg of dry mass) was higher in the ethanol extr...

The increase in mean dry mass per cell in the surviving population of the Ehrlieh aseites tunmr cells after t rea tment with I IN~ was studied with the aid of the interference microscope. The carcinoma cells in animals t reated with a single dose (~.5 mg/kg) of HN~ 5 days after tumor t ransplant showed no change in mean dry mass during the first 8 hours after t reatment . Start ing soInetime be...

The skeletal system of animals provides the support for a variety of activities and functions. For animals such as mammals, which have endoskeletons, research has shown that skeletal investment (mass) scales with body mass to the 1.1 power. In this study, we ask how exoskeletal investment in insects scales with body mass. We measured the body mass and mass of exoskeletal chitin of 551 adult ter...

dry matter production in oak (Quercus robur L.) seedlings and clonal cherry (Prunus avium L. × pseudocerasus Lind.) plants were measured during 19 months of growth in climate-controlled greenhouses at ambient (350 vpm) or elevated (700 vpm) CO2. In both species, the elevated CO2 treatment increased the PPFD saturated-rate of photosynthesis and dry matter production. After two months at elevated...

We investigate the role that dry mergers play in the build-up of massive galaxies within the cold dark matter paradigm. Implementing an empirical shut-off mass scale for star formation, we find a nearly constant dry merger rate of ∼ 6× 10 Mpc Gyr at z 6 1 and a steep decline at larger z. Less than half of these mergers are between two galaxies that are morphologically classified as early-types,...

This study investigates the relationship between tree growth and air mass type variability, using the spatial synoptic classification (SSC) in a bottomland slash pine forest in coastal Alabama (USA). The use of an air mass approach in dendroclimatology is somewhat unconventional and has not been fully explored. However, we believe that it may be useful because the air mass approach represents a...
