    Terrestrial fossil records from the SWAnatolian basins are crucial both for regional correlations and palaeoenvironmental reconstructions. By reassessing biostratigraphic constraints and incorporating new fossil data, we calibrated and reconstructed the late Neogene andQuaternary palaeoenvironments within a regional palaeogeographical framework. The culmination of the Taurides inSWAnatolia was followed by a regional crustal extension from the late Tortonian onwards that created a broad array of NE-trending orogen-top basins with synchronic associations of alluvial fan, fluvial and lacustrine deposits. The terrestrial basins are superimposed on the upper Burdigalian marine units with a c. 7 myr of hiatus that corresponds to a shift from regional shortening to extension. The initial infill of these basins is documented by a transition from marginal alluvial fans and axial fluvial systems into central shallow-perennial lakes coinciding with a climatic shift from warm/humid to arid conditions. The basal alluvial fan deposits abound in fossil macro-mammals of an early Turolian (MN11–12; late Tortonian) age. The Pliocene epoch in the region was punctuated by subhumid/humid conditions resulting in a rise of local base levels and expansion of lakes as evidenced by marsh-swamp deposits containing diverse fossilmammal assemblages indicating late Ruscinian (lateMN15; late Zanclean) ageWe are grateful for the support of the international bilateral project between The Scientific and Technological Research Council of Turkey (TUBITAK) and The Russian Scientific Foundation (RFBR) with grant a number of 111Y192.

    Selective serotonin reuptake inhibitors combined with venlafaxine in depressed patients who had partial response to venlafaxine: four cases

    WOS: 000185187900025PubMed ID: 12921926One third of depressive patients show partial or no response to antidepressant treatment. With partial or nonresponders, treatment strategies are as follows: switching to another antidepressant, augmenting with other psychotropic agents, or combining antidepressants. There are no data in the literature about the positive effect of combining venlafaxine with selective serotonin reuptake inhibitors (SSRIs). In this report, the presented cases had been on at least two different classes of antidepressant medication (or combination of antidepressants) for an adequate time and dose. They showed only a partial response to high dose of venlafaxine but improved after the addition of an SSRI (sertraline, citalopram, or paroxetine) to venlafaxine. The combination treatment was well tolerated in all of the cases. (C) 2003 Elsevier Science Inc. All rights reserved

    Low serum levels of brain-derived neurotrophic factor in patients with schizophrenia do not elevate after antipsychotic treatment

    Brain-derived neurotrophic factor (BDNF) has been suggested to be involved in the etiology of schizophrenia. There is a line of evidence that disruption of neurotrophins could play a role in the etiology of schizophrenia, and antipsychotics show their effect by altering levels of neurotrophins. The aim of this study was to evaluate the effect of antipsychotics on serum BDNF levels and their relationship with the symptoms in patients with schizophrenia. Twenty-two schizophrenia patients were enrolled in the study. The control group consisted of 22 age- and sex-matched physically and mentally healthy volunteers (7 male, 15 female). Serum BDNF levels and the positive and negative syndrome scale (PANSS) scores were recorded at baseline and after 6 weeks of treatment. Serum BDNF levels were also recorded in the control group. Schizophrenia patients who failed to meet 30% improvement in PANSS score were excluded from the study. The baseline serum BDNF levels of schizophrenia patients were lower than those of controls (t=4.56; df=21; p0.05). Although PANSS (for positive symptoms p0.05). Our results support the view that BDNF would be associated with schizophrenia. However, we could not conclude that treatment with antipsychotics alters serum BDNF levels in patients with schizophrenia. (C) 2004 Elsevier Inc. All rights reserved
