    Notes: Summary The kidney growth seen after the induction of experimental diabetes in rats has been compared to the compensatory renal growth after one-sided nephrectomy. After five days the kidney weight had increased from 650 ± 15 mg in a group of controls to 778 ± 21 mg in diabetic rats, and 764 ±17 mg in unilaterally nephrectomised rats. The increased weight was in both groups reflected in an increased DNA content and increased RNA/DNA and protein/DNA ratios. In a group of rats made diabetic and nephrectomised at the same time, kidney weight increased to 953 ± 22 mg after five days. When rats were unilaterally nephrectomised after 20 days of untreated diabetes, compensatory growth was much more pronounced than in non-diabetic rats, kidney weight rising from 780 ± 21 to 1144 ± 39 mg in five days. Similarly, in rats with established compensatory renal hypertrophy, diabetes induced a very rapid growth of the remaining kidney (1226 ± 46 mg after five days).

    Notes: Summary Injection of porcine growth hormone (200 μg) or saline 5 days a week for 16 to 20 weeks in streptozotocin-diabetic rats showed that compared to saline growth hormone produced a 2 1/2-fold larger increase in glomerular capillary basement membrane thickness (2p=0.027). The possible significance of this effect of an elevated level of growth hormone for diabetic microangiopathy is discussed.

    Notes: Summary Streptozotocin diabetic rats have larger kidneys than non-diabetic rats. In the present study the rate of kidney growth during the first seven days of diabetes was correlated with the blood glucose concentration. Over a wide range of blood glucose concentrations (116–340 mg/100 ml) the kidney weight, protein content and protein/DNA ratio were closely correlated with the glucose values.

    Notes: Abstract Spatial and temporal patterns of predation on seeds of the seagrass Phyllospadix torreyi S. Watson were quantified at four sites near Santa Barbara, California, USA. Over a period of four flowering seasons during 1995 to 1998, monthly patterns of seed fall and intensity of seed predation were similar among sites, but were temporally quite variable. Abundance of dispersed seeds varied greatly both among seasons and years. Within any one year, seeds were present in the environment every month, but they peaked in abundance during the fall months following the annual flowering period. Seeds were more abundant during the earlier years of the study. The intensity of predation steadily increased throughout the study period, from a low of ≤10% seeds consumed during 1995 to ∼50% consumption by 1997, and it was not correlated with abundance of seeds in the environment. Pre-dispersal seed loss also was estimated in two flowering seasons by counting the numbers of seeds consumed prior to release from the plant, and was relatively low (〈15%). No differences were detected among the four study sites in patterns of pre-dispersal loss. Field surveys were done at two sites to identify potential seed predators. Three of the most abundant species identified in these surveys were tested in the laboratory to determine size-specific patterns of feeding activity and to assess which early life stages of P. torreyi (fruits within spadices, dehisced fruits, seedlings) were most vulnerable to predation. All three of the early life stages were consumed. The crabs Pugettiaproducta (Randall) and Pachygrapsus crassipes Randall were much more voracious predators than the isopod Idotea resecata Stimpson.

    Notes: Summary Extracts of the taste hair rich tarsi of the pro- and mesothoracic legs of the flyProtophormia terraenovae contain five chromatographically separable α-glucosidases (E.C. 3.2.1.20). These glucosidases were characterized according to their substrate specificities, their Michaelis constants and their pH optima. The enzymes GLU I, III and V show a broad specificity for several α-glucosides (sucrose, maltose, turanose, palatinose, melezitose and p-nitrophenyl-α-glucoside). The GLU II and IV split sucrose especially with extraordinarily high Michaelis constants (0.1–0.2 M). The properties of the fly enzymes were compared with those of other origine (intestine of mammals, yeast), but especially with those of the fly's taste hair rich labella (Morita and coworkers, 1972–1974). The enzyme GLU III exhibits properties indicating that it may be the sugar receptor protein in question.

    Notes: The microcanonical temperature is shown to be a useful concept in calculations of the decay of a small isolated system with well defined energy. A simpler and more transparent description is obtained than in Klots' formulation of finite-heat-bath theory, where the system is represented by a canonical ensemble. As a further illustration of the utility of the microcanonical temperature concept, we discuss a formula derived by Dunbar for the probabilities for excitation of a single oscillator in a collection of harmonic oscillators with well defined total energy. This formula expresses the excitation probabilities in terms of the temperature for a canonical ensemble with mean energy equal to the energy of the system. However, a much improved accuracy is obtained if the canonical temperature and heat capacity are replaced by their microcanonical values. We justify this replacement through a modified derivation, in which the microcanonical temperature appears as the canonical temperature of a fictitious system with level density ρ′(E), the derivative of the level density ρ(E) of the collection of oscillators. © 2001 American Institute of Physics.

    Notes: We present an experimental setup for measuring the electrical conductance through metallic quantum point contacts (QPCs) under constant or time-dependent bias voltage conditions. The response time of the setup is as short as 25 ns and typical bias voltages range from 10 mV to 2 V. A function generator is used as bias voltage supply. With this, voltage bursts with a frequency of up to 100 kHz can be applied to the QPCs, whereby current-to-voltage (I–V) curves can be acquired using a homebuilt, 30 MHz bandwidth I–V converter, and a 100 Msamples/s digital storage oscilloscope. Test experiments on resistors show that nonlinear contributions to the I–V curves are always less than 1% of the current for all applied voltages. From the slope of the I–V curves, the conductance can be determined with an accuracy better than 1%. The QPCs are formed between a single-crystal metal sample and the tip of a scanning tunneling microscope under clean ultrahigh vacuum conditions. We demonstrate how the setup can be used to capture the I–V curves of several metastable states in a Au QPC, as it breaks during a period of 200 μs at room temperature. © 2000 American Institute of Physics.
