Reduction of species diversity which is a significant threat to the earth has been found more important and has attracted attention among ecologists over recent years. This research was carried out to determine the relationships between plant species diversity indices and soil properties by multivariate regression methods in Jamilabad region, Baft, Kerman province, Iran in 2016. Different sites...

آستروسیت ها که عمده ترین سلول های غیر نورونی در مغز می باشند، در پشتیبانی و نگهداری نورون ها نقش دارند. دخالت مسیر پیام رسانی pi3k/akt در ترشح فاکتور محافظ عصبی tgf-? در آستروسیت ها، القا شده با استرادیول، گزارش شده است. در این پایان نامه احتمال شرکت مسیر پیام رسانی canonical wnt در تولید فاکتورهایی از خانواده ی tgf-? نظیر tgf-?و bmp-4 توسط آستروسیت ها بررسی گردید. آستروسیت های جداشده از کورتکس...

BACKGROUND Abnormalities of intracellular calcium handling are widely recognized as a common hallmark of heart failure in animal models and humans. Modifying the interaction of phospholamban (PLB) with the sarcoplasmic reticulum ATPase (SERCA) by PLB mutants improves cardiac function but may also lead to heart failure. In this study we describe the in vivo effects of a new approach to modify th...

This paper presents a multi-layered Kretschmann configuration-based Surface Plasmon Resonance (SPR) biosensor for the detection of urine glucose. The modelling, simulation, and analysis have been done by using Silver (Ag) Gold (Au) layer on low refractive index prism BK-7 separately, which created two structures: structure-I (BK7/Ag/Bio-sample) structure-II (BK7/Au/Bio-sample). Urine samples fr...

BACKGROUND Nowadays, aquatic organisms are used as bio-indicators to assess ecological water quality in western regions, but have hardly been used in an Iranian context. We, therefore, evaluated the suitability of several indices to assess the water quality for an Iranian case study. METHODS Measured data on biotic (fish and macroinvertebrates) and abiotic elements (28 physicochemical and hab...

Here we develop from a long term field experiment an assessment method of interstitial fauna resilience to combined sewer overflows (CSOs) effect. We address the case of “small water courses” for which the ratio of CSOs to natural flow can be 1 to much more. Biotic material was collected in the benthic and hyporheic layers. Biotic material focussed mainly on oligocheates species whose diversity...

ABSTRACT First Person is a series of interviews with the first authors selection papers published in Biology Open, helping researchers promote themselves alongside their papers. Linda Greening author on ‘ Towards an objective measurement sleep quality non-human animals: using horse as model species for creation indices’, BiO. senior lecturer at Hartpury University, currently studying equine beh...

Recognition of desertification criteria and indices and determining the most effective factors on it are the first steps for logical planning to combat desertification. In this study, the sensitivity of the Jaz-Murian region to desertification was evaluated using IMDPA model which is one of the desertification assessment methods in arid and semi-arid regions, on the basis of geology-geomorpholo...
