Effect of native gastric mucus on in vivo hybridization therapies directed at Helicobacter pylori [PDF]

open access: yes, 2015
Helicobacter pylori infects more than 50% of the worldwide population. It is mostly found deep in the gastric mucus lining of the stomach, being a major cause of peptic ulcers and gastric adenocarcinoma. To face the increasing resistance of H.

Chemical evolution of an autonomous DNAzyme with allele-specific gene silencing activity

open access: yesNature Communications, 2023
Low activity has been the primary obstacle impeding the use of DNA enzymes (DNAzymes) as gene silencing agents in clinical applications. Here we describe the chemical evolution of a DNAzyme with strong catalytic activity under near physiological ...

Hfq binding changes the structure of Escherichia coli small noncoding RNAs OxyS and RprA, which are involved in the riboregulation of rpoS [PDF]

open access: yes, 2013
OxyS and RprA are two small noncoding RNAs (sRNAs) that modulate the expression of rpoS, encoding an alternative sigma factor that activates transcription of multiple Escherichia coli stress-response genes. While RprA activates rpoS for translation, OxyS

The metabolism of aged seeds. The ribonucleolytic activity of rye grain embryos of different ages

open access: yesActa Societatis Botanicorum Poloniae, 2014
Winter rye grain, harvested in various years and exhibiting clearly differing viability. was studied. Higher total ribonucleolytic activity was found in the post-ribosomal supernatant than in the ribosomes themselves.

RNA-binding protein immunoprecipitation as a tool to investigate plant miRNA processing interference by regulatory proteins of diverse origin [PDF]

open access: yes, 2018
Background: Due to the nature of viral RNA genomes, RNA viruses depend on many RNA-binding proteins (RBP) of viral and host origin for replication, dissemination and evasion of host RNA degradation pathways.

Spectroscopic/Computational Characterization and the X-ray Structure of the Adduct of the VIVO–Picolinato Complex with RNase A

open access: yesInorganic Chemistry, 2021
The structure, stability, and enzymatic activity of the adduct formed upon the reaction of the V–picolinato (pic) complex [VIVO(pic)2(H2O)], with an octahedral geometry and the water ligand in cis to the V=O group, with the bovine pancreatic ribonuclease

Leishmania braziliensis: isolation of carbohydrate-containing antigen and possibility of its use in the immunodiagnosis of American Cutaneous Leishmaniasis Leishmania braziliensis: isolamento de antígeno contendo carboidrato e a possibilidade de sua aplicação no imunodiagnóstico da Leishmaniose Tegumentar Americana

open access: yesRevista do Instituto de Medicina Tropical de São Paulo, 1995
Leishmania braziliensis is a causative agent of American Cutaneous Leishmaniasis (ACL). The 034-JCG strain, isolated from a patient from the northern region of Paraná State, Brazil, was cultivated in Blood Agar Base medium, lyophilized and submitted to ...

Atypical protein disulfide isomerases (PDI): Comparison of the molecular and catalytic properties of poplar PDI-A and PDI-M with PDI-L1A. [PDF]

open access: yesPLoS ONE, 2017
Protein disulfide isomerases are overwhelmingly multi-modular redox catalysts able to perform the formation, reduction or isomerisation of disulfide bonds. We present here the biochemical characterization of three different poplar PDI isoforms.

Circulating microRNAs -The potential biomarkers for early diagnosis of osteoarthritis

open access: yesTạp chí Khoa học Đại học Mở Thành phố Hồ Chí Minh - Kỹ thuật và Công nghệ, 2020
Osteoarthritis (OA) is the most common form of arthritis and is one of the main causes of joint pain, impaired mobility and physical disability. Early diagnosis of OA is an important factor for effective treatment. However, current diagnostic methods are
