    Notes: Pharmacological manipulation of the ventrolateral pontine reticular formation (vlPRF) of rats has an anticonvulsant effect in the maximal electroshock model of epilepsy. This study presents three anatomical experiments that determine the efferent projections from this region likely to mediate this anticonvulsant effect. In the first, the anterograde tracer biotinylated dextran amine (BDA) was injected into the vlPRF. A strong projection to the ventromedial medullary reticular formation (vmMRF) was revealed which continued only weakly to the spinal cord. In the second experiment, double-label procedures were used to indicate whether the BDA-labelled terminals from the vlPRF make contacts with neurons in vmMRF, retrogradely labelled with cholera-toxin B subunit from the lumbar spinal cord. Sections of the vmMRF were examined by: (i) light microscopy which showed significant overlap between terminals from vlPRF and retrogradely-labelled reticulospinal cells; (ii) confocal microscopy which showed labelled terminals in close association with reticulospinal cell bodies; and (iii) electron microscopy which showed vlPRF terminals making synaptic contact with reticulospinal neurons. Finally, immunohistochemical procedures in combination with anterograde tracing revealed that significant numbers of terminals labelled from vlPRF were also positive for markers of glutamatergic or GABAergic neurotransmission. This suggests that the projection from the vlPRF to the vmMRF is likely to include several different functional components. These connections could represent a final critical link of an anticonvulsant circuit that originates in the dorsal midbrain and projects via relays in the vlPRF and the vmMRF to interact with the low-level motor circuitry in the spinal cord.

    Notes: A review by Campion, Palmer, and Campion (1997) identified 15 elements of interview structure and made predictions regarding how applicants and interviewers might react to these elements. In this 2-sample field survey of 812 interviewees and 592 interviewers from over 502 organizations, interview structure was best described by 4 dimensions: (a) Questioning Consistency, (b) Evaluation Standardization, (c) Question Sophistication, and (d) Rapport Building. Interviewers with formal training and those with a selection rather than recruiting focus employed higher levels of interview structure. In addition, reactions to increased structure were mixed. Both higher structure (Question Sophistication) and lower structure (Rapport Building) were positively related to interviewer reactions. Less than 34% of interviewers had any formal interview training. However, interviewers were confident that they could identify the best candidates regardless of the amount of interview structure employed. Applicants reacted negatively to the increased perceived difficulty of structured interviews, but perceptions of procedural justice were not affected by interview structure.

    Notes: Land-use changes have contributed to increased atmospheric CO2 concentrations. Conversion from natural peatlands to agricultural land has led to widespread subsidence of the peat surface caused by soil compaction and mineralization. To study the net ecosystem exchange of carbon (C) and the contribution of respiration to peat subsidence, eddy covariance measurements were made over pasture on a well-developed, drained peat soil from 22 May 2002 to 21 May 2003. The depth to the water table fluctuated between 0.02 m in winter 2002 to 0.75 m during late summer and early autumn 2003. Peat soil moisture content varied between 0.6 and 0.7 m3 m−3 until the water table dropped below 0.5 m, when moisture content reached 0.38 m3 m−3. Neither depth to water table nor soil moisture was found to have an effect on the rate of night-time respiration (ranging from 0.4–8.0 μmol CO2 m−2 s−1 in winter and summer, respectively). Most of the variance in night-time respiration was explained by changes in the 0.1 m soil temperature (r2=0.93). The highest values for daytime net ecosystem exchange were measured in September 2002, with a maximum of −17.2 μmol CO2 m−2 s−1. Grazing events and soil moisture deficiencies during a short period in summer reduced net CO2 exchange. To establish an annual C balance for this ecosystem, non-linear regression was used to model missing data. Annually integrated (CO2) C exchange for this peat–pasture ecosystem was 45±500 kg C ha−1 yr−1. After including other C exchanges (methane emissions from cows and production of milk), the net annual C loss was 1061±500 kg C ha−1 yr−1.

    Notes: [Auszug] The triplet-based genetic code requires that translating ribosomes maintain the reading frame of a messenger RNA faithfully to ensure correct protein synthesis. However, in programmed -1 ribosomal frameshifting, a specific subversion of frame maintenance takes place, wherein the ribosome is ...
