BACKGROUND Sulindac regresses colorectal adenomas in patients with familial adenomatous polyposis (FAP), although the mechanism of polyp regression is unclear. AIMS To determine whether differences occur in alteration of rectal epithelial apoptotic index and expression of apoptosis related proteins in FAP patients treated with sulindac compared with placebo. PATIENTS Twenty one FAP patients...

The aim of this study is to carry out hydrothermal alteration mapping and structural using ASTER images in order identify indices that could guide mining exploration work the Poli area its surroundings. To achieve this, were first preprocessed correct atmospheric effects remove vegetation influence. Secondly, a lineament was conducted by applying Discrete Wavelet Transform (DWT) algorithms Firs...

Abstract The human alteration of habitats is a major driver in the decline biodiversity worldwide. However, relationships between different forms rarity, including both taxonomic and functional aspects, are poorly known. Two were examined this study: (i) rarity originality lotic fishes; (ii) indices degree alterations. Stream fish communities at 429 stream river sites sampled 2013 2018. fishes ...

Transient hyperopic refractive shifts occur on a timescale of weeks in some patients after initiation of therapy for hyperglycemia, and are usually followed by recovery to the original refraction. Possible lenticular origin of these changes is considered in terms of a paraxial gradient index model. Assuming that the lens thickness and curvatures remain unchanged, as observed in practice, it app...

Abstract The best exposed Early Miocene (820 m. thick. ) shales and interbedded silty sandstones beds of the Pyawbwe Formation at Sakangyi- Thayat area,Magway Region are investigated geochemically by using Siemens SRS- X Ray 303 AS XRF Spectrometer. Major and some trace element concentrations have been determined to achieve their provenance, tectonic setting ,paleoweathering , paleoclimate and ...

waist/hip ratio accounted for only 1·8%. Waist/hip ratio correlated poorly with attractiveness, whereas even small changes in body-mass index radically altered the attractiveness rating (see figure). Further analyses included other bodyshape dimensions, including waist/bust ratio (upper-body shape), bust/hip ratio (degree to which the body has “hourglass” shape), and the leg length/torso length...

Taknar deposit is located about 28 km to the north-west of Bardaskan in the Khorasan-e-Razavi province, which is situated in the north-eastern part of Iran. This deposit is unique, formed within the Taknar formation in the Ordovician time. As a result, it is of much interest to many researchers working in this field. By choosing the lithogeochemical study performed to recognize new exploration ...

Watershed management has different effects on the amount of runoff and sediment and alteration ofhydrological features in a watershed. In this study, the effects of watershed management on runoff was investigated in the Anbaranchaywatershed. For this purpose, the topography data in format of a digital elevation model, land use, soil hydrological groups and watershed managemetrigeon,and also usi...
