[Auszug] As a result of oxidation of chlorpromazine with hydrogen peroxide and peroxidase, Cavanaugh2 obtained a red reaction product which had an absorption maximum at 527 mfx as well as an identical absorption in the ultra-violet as the sulphoxide. It was concluded from kinetic data that this substance ...

The water sorption by adult and embryonic native and insoluble collagen was investigated, along with that of calfskin gelatin. Greater sorption was obtainable with the collagen fractions than with gelatin, but the technique could not distinguish the fractions themselves. The suggestion is made that the greater sorption by collagen over gelatin and differences in apparent wettability between the adult and embryonic insoluble collagen might be explained by the formation of helical grooves with aging. Density measurements of the collagen fractions indicate that collagen becomes more crystalline with aging. This also applied to the insoluble collagen. These results are consistent with the view that differences in collagen solubility are due to differences in molecular ordering. The density of the insoluble collagens and gelatin passes through a maximum at 3-4% sorbed water. The phenomenon is explained on the basis of water bridges comprised of a single water molecule double hydrogen bonded to closely aligned chains. A discussion is presented in this connection. A calculation based on the density yields a molecular volume of 4.32 × 10-19 cm.3 For tropocollagen. This is in agreement with the molecular dimensions and consistent with the idea that collagen is formed from an aggregation of the monomer.

We investigate the thickness dependent properties of manganite films characterized by colossal negative magnetoresistance. Ultrathin, wedge-type films (0–120 Å) of La0.7Ba0.3MnO3 were deposited by laser ablation onto SrTiO3 and LaAlO3 substrates. The films were patterned into strips of different thickness and magneto-transport measurements were performed at temperatures between 5 and 290 K and in magnetic fields up to 5 T. Atomic force- and transmission electron microscopy were done to correlate the microstructure with the transport data. The resistivity of the films increases slightly with decreasing thickness due to substrate-induced compressive strain. Below 50 Å, the resistivity rises abruptly indicating a crossover to discontinuous and finally island-like film growth as confirmed by the microstructural techniques. At thicknesses slightly above the threshold for percolative conduction ((approximate)30 Å), an enhanced low-field magnetoresistance was observed as a signature of spin-dependent tunneling. © 2001 American Institute of Physics.

A novel biopolymer composed of porcine gelatin and dextran was used in a randomized controlled pilot clinical trial to treat diabetic foot ulcers to establish safety profile and evaluate effect on wound closure. Fifty-six patients were prospectively randomized at 10 centers (control = 25; E-Matrix = 31). Control patients received routine sharp debridement, off-loading, and hydrogel dressings applied daily. E-Matrix patients received identical wound care with the addition of monthly subcutaneous injections of E-Matrix under the wound surface. Patients were monitored for 12 weeks using wound planimetry and photography. Primary endpoint was safety as measured by adverse event reporting and clinical laboratory analysis. Secondary endpoint was wound closure based on intent to treat.There was no significant difference in the rate of adverse events between treated and control subjects. Overall closure rate for E-Matrix treated wounds was 42%(13 of 31 subjects) compared to 32%(8 of 25 subjects) for controls. Subgroup analysis suggested that E-Matrix may be more effective than control for treatment of larger (〉2 cm2) and older (〉17 weeks duration) wounds (see table).〈table frame="topbot"〉〈tgroup cols="5" align="left"〉〈colspec colnum="1" colname="col1" align="left"/〉〈colspec colnum="2" colname="col2" align="left"/〉〈colspec colnum="3" colname="col3" align="center"/〉〈colspec colnum="4" colname="col4" align="center"/〉〈colspec colnum="5" colname="col5" align="center"/〉〈thead valign="bottom"〉〈row rowsep="1"〉ParameterTreatment GroupNClosed%Closed〈tbody valign="top"〉Size 〉2 cmE-Matrix17847%Control14429%Ulcer duration 〉17 weeksE-Matrix15640%Control15320% Although the study is insufficiently powered to evaluate statistical significance, E-Matrix demonstrated a similar safety profile to control treatment with trends toward improved healing in larger and older wounds. Further randomized trials are necessary to confirm these promising initial results.

The effect of three different vertical structures of a perennial ryegrass-dominated sward, defined by pseudostem heights (cm) — 1·3 low (L), 2·5 medium (M) and 3·5 high (H) — on the bite depth and selection of plant parts within the grazed horizon of the sward by sheep and guanacos was studied. The bite depth (cm) was similar between sheep and guanacos across the different swards (L, 1·5; M, 3·6; H, 3·8) and was related to pre-grazing sward surface height rather than to pseudostem height. There were differences in diet composition between species that were related to differences in selection for plant parts. Sheep had a higher proportion of green leaf in the diet than did guanacos in L (0·84 vs. 0·71, P 〈 0·05) and M (0·75 vs. 0·59, P 〈 0·05) swards, and possibly selected this plant part in H swards in which the proportion of green leaf in the grazed horizon was low (0·45–0·50). Guanacos had a higher proportion of dead leaf and sheath in the diet than did sheep in L (0·23 vs. 0·09, P 〈 0·05) and M (0·30 vs. 0·18, P 〈 0·05) swards, and possibly selected this plant part on these swards, in which the proportion of green leaf in the grazed horizon was high (0·70–0·95). The proportion of pseudostem in the diet of sheep and guanacos was similar across all swards (0·03) and was generally much lower than that in the grazed horizon (0·01–0·18). Guanacos had a higher proportion of dead stem in the diet than did sheep (0·06 vs. 0·02, P 〈 0·05) across all swards, but the proportion was similar to that in the grazed horizon of each sward.
