مادة آلی محلول رنگی (CDOM) مقیاس مهمی در سنجش کیفیت آب است. می‌توان اذعان کرد CDOM نور موجود لایه‌های را کاهش می‌دهد و فعالیت‌های بیولوژیکی فتوسنتز مختل می‌کند سرانجام، مانع رشد جمعیت فیتوپلانکتون‌‌هایی می‌شود که برای زنجیرة غذای آبزیان ضروری‌اند. بیشتر تحقیق‌هایی تا کنون به انجام رسیده، از طول موج خاصی اندازه‌گیری ضریب جذب استفاده شده است اما، این تحقیق، امکان گسترة‌ وسیعی باندهای طیف مرئی، تع...

To investigate the influence of hindbrain segmentation on craniofacial patterning we have studied the long term fate of neural crest (NC) subpopulations of individual rhombomeres (r), using quail-chick chimeras. Mapping of all skeletal and muscle connective tissues developing from these small regions revealed several novel features of the cranial neural crest. First, the mandibular arch skeleto...

Aerobic granular sludge reactors usually operate in sequential batch mode, although this configuration limits the treatment of large volumes wastewater, and they require a storage system. To implement technology at full-scale, it would be necessary to design simple compact continuous-flow bioreactor able treat larger wastewater. In study, four aerobic single-chamber (R1, R2, R3 R4) were designe...

Changes of immune system in adolescents during the 2020-2021 pandemic have not been sufficiently studied. The paper concerns features flow cytometric indexes among children different age groups and their immunoglobulin status. cohort was classified into 12 categories (3 subgroups, 4 relative to status). aim this work investigate changes immunograms COVID evaluated by means cytometry. methodolog...

the rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (pgpr). in this study, the isolation andidentification of rhizobacteria from orange (citrus sinensis) orchards using 16s rrna gene, as well asbiological and biochemical assays is reported. analysis of 16s rrna gene was confirmed bybiological and ...

Purpose To investigate the effect of Ozurdex (dexamethasone intravitreal implant) on multifocal electroretinography (mfERG) findings during the treatment of macular edema secondary to the central retinal vein occlusion (CRVO). Methods Fifteen eyes of 15 patients who were treated with Ozurdex implant due to CRVO-related macular edema were included in this study. Best corrected visual acuity (B...

INTRODUCTION Tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) is a tumour necrosis factor (TNF) family member capable of inducing apoptosis in many cell types. METHODS Using immunohistochemistry, terminal deoxynucleotidyl transferase biotin-dUTP nick end labelling (TUNEL) and real-time PCR we investigated the expression of TRAIL, TRAIL receptors and several key molecules of th...

Four virus-specific transcripts have been identified in murine cells infected with Minute-Virus-of-Mice (MVM). These RNAs, 4.8, 3.3, 3.0 and 1.8 kilobases in length, designated R1 to R4 respectively, are all transcribed from the virion (-) strand of DNA and they are all polyadenylated and spliced. The R1 transcript is derived from sequences that reside on the genome between 4.0 and 95 map units...

The formation of nucleoprotein complexes between the Escherichia coli initiator protein DnaA and the replication origin oriC was analysed in vitro by band-shift assays and electron microscopy. DnaA protein binds equally well to linear and supercoiled oriC substrates as revealed by analysis of the binding preference to individual DnaA boxes (9-mer repeats) in oriC, and by a competition band-shif...

This research aimed to increase functional value of broiler-chicken meat containing high antioxidant and low cholesterol through substitution of soybean meal (SBM) with Indigofera zollingeriana top leaf meal (ILM). The experiment used 160 day old broiler chicken (Cobb strain). The experimental chicken were provided dietary treatments when they were 15-days old (initial body weight of 460.5±1.56...
