Changes in ionotropic glutamate (Glu) N-methyl-D-aspartic acid (NMDA), and 2-amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl)propionic acid (AMPA) receptors in rat forebrain regions were autoradiographically quantified after continuous infusion of JL 13 [(5-(4-methylpiperazin-1-yl)-8-chloro-pyrido[2,3-b][1,5]benzoxazepine furnarate] for 28 days using osmotic minipumps, and compared to the effects of representative typical (haloperidol) and atypical (clozapine, olanzapine, and risperidone) antipsychotic drugs from previous studies. Similar to other atypical and not typical antipsychotics, JL 13 decreased labeling of NMDA receptors in medial and lateral caudate-putamen (CPu; by 40%). These findings indicate that downregulation of NMDA receptors by JL 13 and other atypical antipsychotic agents in CPu may contribute to their low risk of extrapyramidal side effects. In addition, and similar to olanzapine and risperidone, JL 13 increased AMPA receptor binding in CPu (by 42%). Changes in AMPA receptors may contribute to psychopharmacological properties of JL 13 and other atypical agents. Similar to clozapine, JL 13 did not alter levels of NMDA and AMPA receptors in hippocampus and entorhinal cortex. Long-term effects of JL 13 on ionotropic Glu receptors, as well as on other dopamine and serotonin receptors, support the atypical antipsychotic profile of this novel agent. [less ▲]

Changes in dopamine (DA) D-1, D-2, D-3, and D-4 receptors and serotonin 5-HT1A and 5-HT2A receptors in rat forebrain regions were autoradiographically quantified after continuous infusion of JL 13 [(5-(4-methylpiperazin-1-yl)8-chloro-pyrido[2,3-b][1,5]benzoxazepine fumarate] for 28 days with osmotic minipumps and compared with the effects of other typical (fluphenazine) and atypical (clozapine, olanzapine, and risperidone) antipsychotic drugs from previous studies. Similar to other typical and atypical antipsychotics, JL 13 increased labeling of D2 receptors in medial prefrontal cortex (MPC) and hippocampus (HIP) and D-4 receptors in nucleus accumbens (NAc), caudate-putamen (CPu), and HIP In addition, JL 13 increased 5-HT1A and decreased 5-HT2A receptors in MPC and dorsolateral frontal cortex (DFC), an effect shared by atypical antipsychotics, and may contribute to their psychopharmacological properties. Clozapine and JL 13, but not other antipsychotics, spared D2 receptors in CPu, which may reflect their ability to induce minimal extrapyramidal side effects. In addition, JL 13 but not other typical and atypical antipsychotic drugs increased abundance of D, receptors in CPu and NAc. JL 13 as well as other antipsychotic agents did not alter levels of forebrain D3 receptors. An atypical-like profile of JL 13 on DA and 5-HT receptor subtypes should encourage further development of this compound as a novel atypical anti psychotic drug. (c) 2006Wiley-Liss, Inc. [less ▲]

OBJECTIVE: To determine in postmenopausal women the long-term effects on carbohydrate metabolism of the administration of oral micronized 17 beta-estradiol (2 mg/day continuously) and cyclical dydrogesterone (10 mg/day for 14 days per 28-day cycle). METHODS: A 2-year open-label prospective, non-comparative study was carried out of 13 healthy postmenopausal women receiving cyclical estradiol and dydrogesterone and serving as their own controls. Concentrations of blood glucose, plasma insulin, C-peptide, glucagon and free fatty acids (FFAs) were determined before treatment (base-line) and at 6, 12 and 24 months of hormone replacement therapy under fasting conditions and during a standard 75-g, 3-h, oral glucose tolerance test (OGTT). RESULTS: Fasting blood glucose levels were unchanged throughout the study, and the mean areas under the curves (AUCs) for glucose response increased slightly but non-significantly versus baseline; fasting plasma insulin levels tended a decrease, and AUCs for insulin responses to the glucose load fell by 23% from baseline (not significant); fasting C-peptide levels and AUCs were unchanged; plasma glucagon fasting levels and responses were in the normal range and stable throughout the study; and plasma FFA fasting levels decreased significantly, as well as FFA AUCs during OGTTs, at the 12th and 24th months of the study. CONCLUSIONS: During a 2-year treatment with oral estradiol and cyclical dydrogesterone, a direct progesterone derivative, tolerance to glucose was unchanged, fasting plasma insulin and insulin response to repeated glucose loads were decreased, and C-peptide levels remained unchanged, indicating a potential improvement in insulin sensitivity and clearance, as in younger women; additionally, a slightly enhanced antilipolytic activity of insulin was observed.

Limited placebo-controlled data are available to assess the long-term fracture efficacy of bisphosphonates. In order to determine the effects of 5 years of risedronate treatment, we extended a 3-year, placebo-controlled vertebral fracture study in osteoporotic women for an additional 2 years; women who entered the extension study continued to receive 5 mg risedronate or placebo according to the original randomization, with maintenance of blinding. End points included vertebral and nonvertebral fracture assessments, bone mineral density measurements, and changes in biochemical markers of bone turnover. A total of 265 women (placebo, 130; 5 mg risedronate, 135) entered the study extension and 220 (83%) completed the additional 2 years. Fracture results observed in the study extension were consistent with those observed in the first 3 years. The risk of new vertebral fractures was significantly reduced with risedronate treatment in years 4 and 5 by 59% (95% confidence interval, 19 to 79%, P = 0.01) compared with a 49% reduction in the first 3 years. Rapid and significant decreases in markers of bone turnover observed in the first 3 years were similarly maintained in the next 2 years of treatment. Increases in spine and hip bone mineral density that occurred in the risedronate group during the first 3 years were maintained or increased with a further 2 years of treatment. The mean increase from baseline in lumbar spine BMD over 5 years was 9.3% (P < 0.001). This study demonstrates that the effects of risedronate over 3 years on vertebral fracture and BMD are maintained with a further 2 years of treatment. (C) 2003 Elsevier Science (USA).

Methanol (CH3OH) is the second most abundant organic compound in the Earth’s atmosphere after methane. In this work, we present the first long-term time series of methanol total, lower tropospheric and upper tropospheric-lower stratospheric partial columns derived from the analysis of high resolution Fourier transform infrared solar spectra recorded at the Jungfraujoch station (46.5°N, 3580 m a.s.l.). The retrieval of methanol is very challenging due to strong absorptions of ozone in the region of the selected 8 band of CH3OH. Two wide spectral intervals have been defined and adjusted in order to maximize the information content. Methanol does not exhibit a significant trend over the 1995-2012 time period, but a strong seasonal modulation characterized by maximum values and variability in June-July, minimum columns in winter and a peak-to-peak amplitude of 130 %. In situ measurements performed at the Jungfraujoch and ACE-FTS occultations give similar results for the methanol seasonal variation. The total and lower tropospheric columns are also compared with IMAGESv2 model simulations. There is no systematic bias between the observations and IMAGESv2 but the model underestimates the peak-to-peak amplitude of the seasonal modulations. [less ▲]

The average tropospheric volume mixing ratios of chlorofluorocarbon 12 (CCl2F2) have been retrieved from high-spectral resolution ground-based infrared solar-absorption spectra recorded from March 1982 to October 2003 with the McMath Fourier transform spectrometer at the US National Solar Observatory facility on Kitt Peak in southern Arizona (31.9degreesN, 111.6degreesW, 2.09 km altitude). The retrievals are based on fits to the unresolved v(8) band Q-branches near 922 cm(-1) using the SFIT2 retrieval algorithm. The annual increase rate was equal to (16.88 +/- 1.37) parts per trillion (10(-12)) by volume at the beginning of the time series, March 1982, or (4.77 +/- 0.04)%, 1 sigma, declining progressively to (2.49 +/- 1.24) parts per trillion, by volume at the end, October 2003, or (0.46 +/- 0.24)%, 1 sigma. Average tropospheric mixing ratios from the solar spectra have been compared with average surface flask and in situ sampling measurements from the Climate Monitoring and Diagnostics Laboratory (CMDL) station at Niwot Ridge, CO, (USA) (40.0degreesN, 105.5degreesW, 3013 m altitude). The average ratio and standard deviation of the monthly means of the retrieved tropospheric mixing ratios relative to the CMDL surface mixing ratios is (1.01 +/- 0.03) for the overlapping time period. Both datasets demonstrate the progressive impact of the Montreal protocol and its strengthening amendments on the trend of CCl2F2, though a tropospheric decrease has yet to be observed.

Long-term monitoring activities of some 20 atmospheric constituents are continuing at the International Scientific Station of the Jungfraujoch, Switzerland, based on remote infra-red solar observations with high spectral resolution Fourier transform spectrometers. As a contribution to non-CO2 greenhouse gas investigations, we report the trends observed in the vertical column abundances measured regularly since the mid-1980s for CH4, N2O, CO, CCl2F2, CHClF2 and SF6. With the exception of CO, all species show positive rates of change in their near past atmospheric loading, those of CH4, N2O and CCl2F2 having slowed significantly during the more recent years. The derived rates of change will be compared to findings resulting from ground-level in situ investigations at latitudes similar to that of the Jungfraujoch, and be interpreted in terms of resulting global loading changes.
