Paleocene-Miocene sediments in the central part of the Gorgan Plain were studied to evaluate lithostratigraphy, biostratigraphy and reconstruction of the paleogeography of the South Caspian Basin (SCB). Based on nannofossils distribution in the studied interval, the following points were identified: Foram layers equivalent sediments have Thanetian –Eocene age and Upper Maykop- Diatom equivalent sediments have Middle-Late Miocene age. Evaluation of the nannofossils distribution in the studied interval has clarified a major unconformity between lower Paleocene-Eocene sediments and the upper Middle-late Miocene sediments. This unconformity is coincident with collisional event of the Afro-Arabia and Eurasia Plates and rising of the surrounding mountain ranges around the Caspian Basin including Alborz and Kopet-Dagh Mountains. Nannofossils distribution of the studied succession displays that the SCB was connected to the Black Sea and Mediterranean Basin in the lower Middle Miocene and was isolated in the Middle-Late Miocene. The interpreted east-west running seismic lines displays a clear increase in the sediment thickness and accommodation space from eastern to western part of the Gorgan Plain. The higher available accommodation space from east to west of the Gorgan Plain led to a delay in the subaerial exposure in the western part of the Gorgan Plain due to rising of the Kopet-Dagh and Alborz Ranges. This interpretation is consistent with the lack of the Paleocene-Eocene sediments and presence of the Cretaceous sediments below the major unconformity in the eastern part of the Gorgan Plain and presence of the Paleocene-Eocene sediment below the unconformity in the studied area.   

Patello femoral pain syndrome is one of the most common orthopeadics complains, which effect athletes, militaries and ordinary people. The symptoms is idiopathic disease, but one of the most important reason for this disease can be the structural problem of lower limb and one of the efficient method of conservative treatment of patients with patello femoral pain syndrome can be using neoprene palumbo and geno direxa stable orthoses, but there is only a few experimental researches supporting the effects of these orthoses. This study was designed to determine the effects of neoprene palumbo and geno direxa stable on pain and daily activity of patients with patello femoral pain syndrome.

In this clinical trial study 30 male patients (18-40 years old) with patello femoral pain syndrome randomly were divided in 2 groups of 15 patients. Which were placed in Neoprene palumbo and Geno direxa stable orthoses groups respectively. The pain intensity and activity of daily living joint rigidity were assessed before, during and 3 weeks after treatment by visual analogue scale (VAS) and KOOS questionnaire. Following both orthoses application data were analyzed using pair and independent t-test.

In both groups the mean of pain intensity decreased and daily physical activity increased after treatment (P<0.05), but there was not significant difference between neoprene palumbo and geno direxa stable methods, on pain and daily physical activities.

This study indicated that Neoprene palumbo and geno direxa stable orthoses improved the sign of patello femoral pain syndrome including pain intensity and daily life, activity.
