Ribosomal RNA (rRNA) isolated from Wolinella recta and seven related bacteria was examined by agarose gel electrophoresis. The 23S rRNA molecule could not be detected in W. recta, Wolinella curva, Bacteroides gracilis, or Bacteroides ureolyticus. In place of the 23S molecule, there were three smaller molecules of approximately 1700, 650, and 600 bases designated 23S alpha, 23S beta, and 23S del...

background: hla b27 is a sub class of human leukocyte antigen (hla) class i molecule. it was known as the first genetic risk factor associating with ankylosing spondylitis (as). allele frequency of hla-b27 alleles is different across populations. the present study is aimed to investigate the prevalence of hla-b27 in patients referred to danesh clinical laboratory during 2014 to 2015. methods an...

1. The hydrolysis of urea catalyzed by jack bean meal has been followed by determining colorimetrically after Nesslerization the ammonia nitrogen, and volumetrically the carbon dioxide liberated at successive intervals during the reaction. During the early part of hydrolysis the rate of ammonia or carbon dioxide liberation is constant for all the urease solutions which were used. 2. When log ra...

The analysis of fucoxanthin (FCX) in algal biomasses presents some limitations, especially regarding the sample preservation after collection until extraction pigment. FCX stability was evaluated biomass samples one diatom and three brown seaweed species (Phaeophyceae) their extracts stored at -20ºC -80ºC, for 60 days. Fucoxanthin quantified through UHPLC-DAD. methanolic micro/macroalga -80ºC w...

conclusions vancomycin nephrotoxicity is common but usually reversible and has readily manageable adverse effect. urine kim-1 was not more accurate than serum or urine creatinine in detecting vancomycin nephrotoxicity in our study population. results thirteen out of the 52 recruited patients (25%) developed nephrotoxicity, with a mean ± standard deviation onset of 11.46 ± 7.56 days. furosemide ...

(57) ABSTRACT Micro-cavity resonant sensors have outer surfaces that are functionalized using click chemistry, e.g., involving a cycloaddition reaction of an alkyne functional group and an azide functional group. A first polymer linking element binds to an outer surface of the micro-cavity and has an azide functional group, which bonds to an alkyne functional group of a second polymer linking e...

Nanopore-based DNA sequencing is an emerging technology that may soon overcome even the current next-generation sequencing from the viewpoint of DNA sequencing cost and throughput. In this paper, we will show that recent advances of the “pretreatment” process using various nanostructures such as nanopillars, nanowires, and nanoslits structures inside microchannel. In addition, another type of m...

Micro RNAs are small non coding RNA molecule that plays a vital role in post transcriptional gene regulation by either translational repression or by inducing mRNA cleavage. These small non coding RNAs have emerged as one of the master regulators of plant growth and development. Recent studies have revealed their role in abiotic stress responses. Expression level of several miRNA changes when e...

Organic micro/nanocrystals based on small organic molecules have drawn extensive attention due to their potential application in field-effect transistors, electrochemical sensors, solar cells, etc. Herein, the recent advances for from perspective of molecule aggregation mode, morphology modulation, and optical property modulation are reviewed. The stacking mode intermolecular interaction depend...
