Recovery of prokaryotic body fossils from methane seep carbonates such as those of the Cretaceous Tepee Buttes of Colorado serves as a model for sampling in future astrobiological missions. The fossils, found primarily at the interface between paragenetic fabrics, suggest a sharp physicochemical gradient. Evidence of these microbial fossils occurs at a variety of scales. In the field, microbial...

The Skellefte mining District is located in northern Sweden and comprises Palaeoproterozoic, metamorphosed, supracrustal rocks and associated intrusive rocks, which are all host to several ore deposits. Modelling was performed in the GoCAD software platform, using structural geology and petrology as well as magnetic, gravity, seismic, electric and electromagnetic geophysical data, in order to p...

This paper summarises the use of digital remotely sensed data for Quaternary deposits mapping in central Sweden. Landsat TM scene of the beginning of May 1985 was applied. Only six groups of quaternary deposits were distinguished. The classification accuracy of the resultant map was about 50 % in average. Comparison was done with the existing map of Quaternary deposits.

1 Mustard gas is a lipophilic, highly cytotoxic agent that rapidly penetrates tissue, and the eye is one of the organs mostly affected,[1] but skin, respiratory, gastrointestinal, and renal systems as well as the bone marrow may also be affected.[2] Mustard gas related ocular injuries can be divided into immediate, chronic, and delayed‐onset phases. Acute manifestations of varying degrees, incl...

Background: The effect of corticosteroid therapy on corneal wound healing is controversial. The objective of this study was to evaluate the effects of combination therapy with dexametha-sone and acetylcysteine at different times and durations on experimentally-induced corneal wounds and haze in rabbits. Methods: Eighteen adult New Zealand white rabbits were divided into three groups of ...

Background/Objective: Hyperphosphatemia is the consequence of end stage renal failure. Inadequate control of serum phosphorus results in elevated Ca×P product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification.  In this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis patie...

Background: Correlations between bone marrow, heart, kidney, liver, skin and lung transplant rejection or survival with human cytokine gene polymorphisms have been described. There are also reports about the role of cytokines and Tumor Necrosis Factors-Alpha (TNF-α) on corneal transplant in animal models. Further studies are needed to clarify the role of cytokines in corneal allograft rejection...
