(Brazilian Society of Urology, 2015)Introduction: Ureteral obstruction is a common pathology and caused kidney fibrosis and dysfunction at late period. In this present, we investigated the antifibrotic and antiinflammatory effects of montelukast which is ... -
Bioactive content of Rosa canina biotypes from Turkey
(Scibulcom Ltd., 2017)Rose hips have been used as medicinal and aromatic plants for a long time throughout Turkey. The plant has been the focus of many recent studies due to its potential effects on treatment and prevention of several diseases. ... -
Bioactive content of rose hips of different wildly grown rosa dumalis genotypes
(Academic Press, 2016)A rose hip is the fruit of a rose plant and mostly belongs to Rosa canina and Rosa dumalis. These species are genuine found as wild in natural conditions, while in some countries are cultivated for their hips that are ... -
Biodiversity and characterization of gram-positive, catalase-positive cocci isolated from pastırma produced under different curing processes
(TUBITAK, 2019)The aim of this study was to determine the effects of different curing temperatures (4 °C or 10 °C) and agents (KNO 3 or NaNO 2 ) on microbiological and physicochemical properties of pastırma and diversity of gram-positive, ... -
Biodiversity and Landscape Use of Sea Buckthorn (Hippophae rhamnoides L.) in the Coruh Valley of Turkey [Sanddorn (Hippophae rhamnoides L.) im Coruh-Tal (Türkei): Biologische Vielfalt und Landschaftsnutzung]
(Springer Verlag, 2015)The Sea buckthorn, one of the most important wild edible fruits widely grown in Northeastern part of Turkey, is characterized by resistance to hard environmental conditions and looks spectacular, especially in autumn and ... -
Biosorption of CR (VI) onto pseudevernia furfuracea /aqueous solution interface
(2012)This study addresses the removal of a heavy metal, Cr (VI), from aqueous solutions by using dried Psedeuvernia furforcea biomass as biosorbent. The effects of factors, such as the initial chromium concentration, contact ... -
Biosorption properties of Morus alba L. for Cd (II) ions removal from aqueous solutions
(2013)The abundantly available industrial waste product Morus alba L. pomace (MAP) is one of the cost-effective biosorbent for removal of metal ions from aqueous solutions. Hence, in the present study, we aimed to test the ability ... -
Bleeding characteristics of high consistency heavyweight concrete mixtures
(Elsevier Ltd, 2019)Bleeding, a type of static segregation derives from density difference of concrete ingredients in fresh state. Due to having this difference higher than normal weight counterparts, heavyweight concrete is more susceptible ... -
