Study of planktonic morphotype of the Abderaz Formation at type section, Iran

Abderaz Formation at its type section with an age of Turonian-Early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups. The first group is characterized by trochospiral tests usually indicate shallow waters, the second group contains forms with strong ornamentations and the primary keels representing mid waters and finally compact trochospiral tests with keels known as deep water indices are included in the third group. Studies on the morphotypes showed a regressive cycle for Abderaz Formation

Study of Sea level changes with Leckie method of the Abderaz Formation (Middle Turonian-Early Campanian) at type section based on foraminifera

In this research the Abderaz Formation at its type section with an age of Turonian-early Campanian and a thickness of 300 m containing.light grey shale and marls was investigated. Statistical Studise of the morphotype groups of planktonic foraminifera shows that the majority of them are of shallow water forms (SWF) and deep water forms (DWF) and planktonic to benthic ratio is high indicating specific condition of oligotrophy and sedimentation in a relatively deeper marine conditio

Palaeobathymetry of the Abderaz Formation using foraminifera, Iran

Abderaz Formation at its type section with an age of Turonian-early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups. The first group is characterized by trochospiral tests usually indicate shallow waters, the second group contains forms with strong ornamentations and the primary keels representing mid waters and finally compact trochospiral tests with keels known as deep water indices are included in the third group. Studies on the morphotypes showed a regressive cycle for Abderaz Formation. Also the planktonic to benthic ratio was calculated using Depth = e^(3.58718 + (0.03534 × %*p)^ equilibrium which explains that at the deposits 400 meter at total part of in this Formation. This study was intended to explore the marine sedimentation of Abderaz Formation in (outer neritic-upper bathyal) restrict and the provided curves from morphotypes changes are in full agreement with the curves of the sea level changes and planktonic foraminifer to epifauna benthic ratio

The study of the umbilical system in planktonic foraminifera in relation with depth of the Ziarat-kola section at the Maastrichtian, Central Alborz, IRAN

The main aim of this research is study of the planktonic foraminifera morphogroups distinction genus to perform by changing the umbilicus area in Ziarat-kola section to find novel results. Therefore, original objection at this research considers the cause of organizing umbilicus structures (Lip, Portici, Tegilla) at this protests. it seems that phylogeny trend entirely the changes of planktonic foraminifera changing from lip at primary morphogroup to tegilla at development shape which continued this phylogeny trend opening become entirely umbilicus that this trend accompanied to increasing deep. Therefore, the study of planktonic foraminifera morphotype, and recognizing, the obtained results from planktonic foraminifera analysis percent and their comparison with umbilicus structures area diagrams at this section indicats the increasing morphotype three accompany with increase in sea level that here dominated portici and tegilla structure with compressed opening and with decrease of morphotype three which showed decrease sea level, opening structure (lip) dominated. These trends follows the from Pascal law at Ziarat-kola section of the research

COX inhibition: Catalepsy and Striatum Dopaminergic-GABAergic-Glutamatergic Neurotransmission

Selective COX-2 and COX-1 inhibitors were administered (i.p. acutely) to normal and parkinsonian rats, followed by the analysis of the striatal dopamine, GABA and glutamate concentrations using the microdialysis technique, simultaneously, the catalepsy of animals was evaluated. Selective COX-2 inhibition showed improving effects on the catalepsy followed by decreasing the striatum glutamatergic-GABAergic and enhancing the dopaminergic neurotransmission. Nonetheless COX inhibition had no significant improving effects on damaged Substantia Nigra Pars Compacta (SNc) neurons

Biostratigraphic Study of the Gurpi Formation Based on Planktonic Foraminifera In Lar Area (Kuh-e-kurdeh Section)

The study of planktonic foraminifera of the Gurpi formations at Lar area (Kuh-e-kurdeh section) enables me to find the most standard biozones defined in mediterranean regions, especially Tethysian domain. Five biozones were determined. Biozones I (Globotruncanita elevata zone) and II (Globotruncana ventricosa zone) and III (Radotruncana calcarata zone) indicate the Early Campanian and Middle and Late Campanian, respectively. Biozones IV (Globotruncanita stuarti zone) and V (Gansserina gansseri zone) suggest the Early and Middle Maastrichtian, respectively. In the Late Maastrichtian, due to decreasing in water depth at the study area, Abathomphalus mayaroensis zone defined in Tethysian domain was not recognised.
