We used 40 ± 5 nm gold nanoparticles (GNPs) as colorimetric sensor to visually detect swine-specific conserved sequence and nucleotide mismatch in PCR-amplified and non-amplified mitochondrial DNA mixtures to authenticate species. Colloidal GNPs changed color from pinkish-red to gray-purple in 2 mM PBS. Visually observed results were clearly reflected by the dramatic reduction of surface plasmo...
The present research analysed the challenges and effectiveness of using SHAD social network in COVID-19 era from perspective teachers, parents, students middle schools Tehran. sample size for qualitative was based on theoretical saturation, data were collected through purposive judgements snowball techniques. Thematic analysis used to consider 75 interviews. Eight themes attained 43 subcategori...
This study reviewed the validity of using scales Hilsa Shad (Tenualosa ilisha) and other migratory species as a tool to estimate age, growth, maturity schedule migration. were used long ago, proved in several studies. Most these studies showed that could give valuable information, which be benchmarks fisheries plans for future successful management policies. Bt it needs Patience precision extra...
Local ecological knowledge can provide a unique source of data for conservation, especially in efforts to investigate the status of rare or possibly extinct species, but it is unlikely to remain constant over time. Loss of perspective about past ecological conditions caused by lack of communication between generations may create “shifting baseline syndrome,” in which younger generations are les...
Defining habitat suitability criteria (HSC) of aquatic biota can be a key component to environmental flow science. HSC can be developed through numerous methods; however, few studies have evaluated the consistency of HSC developed by different methodologies. We directly compared HSC for depth and velocity developed by the Delphi method (expert opinion) and by two primary literature meta-analyse...
چکیده: مول هیداتیفورم یک حاملگی غیر طبیعی انسانی است که طبق ویژگی های هیستولوژیک، ژنتیک، سونوگرافی و کلینیکی به صورت مول هیداتیفورم کامل (chm) و مول هیداتیفورم ناقص (phm) دسته بندی می شود. تمایز قایل شدن بین chm و phm با استفاده از نشانه های هیستولوژیک به تنهایی مشکل است، مول کامل رایج ترین فرم برای تبدیل شدن به کوریوکارسینوما می باشد و مول هتروزیگوت این استعداد را افزایش می دهد. ژن nlrp7 با م...
