Oligonucleotide separation techniques for purification and analysis: What can we learn for today's tasks?

ELECTROPHORESIS, Volume 43, Issue 23-24, Page 2402-2427, December 2022., 2022
Abstract Nucleic acids are the blueprint of life. They are not only the construction plan of the single cell or higher associations of them, but also necessary for function, communication and regulation. Due to the pandemic, the attention shifted in particular to their therapeutic potential as a vaccine. As pharmaceutical oligonucleotides are unique in

The impact of dioctyl phthalate exposure on multiple organ systems and gut microbiota in mice

Heliyon, 2023
Dioctyl phthalate, commonly known as bis(2-ethylhexyl) phthalate (DEHP), is a widely used plasticizer in various industries and has been shown to directly or indirectly impact human health. However, there is a lack of comprehensive studies evaluating the

Antibiotic susceptibility, heteroresistance, and updated treatment strategies in helicobacter pylori infection [PDF]

, 2017
In this review, we discuss the problem of antibiotic resistance, heteroresistance, the utility of cultures and antibiotic susceptibility tests in Helicobacter pylori (Hp) eradication, as well as the updated treatment strategies for this infection.

Multiple pathways of plasmid DNA transfer in Helicobacter pylori [PDF]

, 2012
Many Helicobacter pylori (Hp) strains carry cryptic plasmids of different size and gene content, the function of which is not well understood. A subgroup of these plasmids (e.g.

A comparative study of clinicopathological features between chronic cholecystitis patients with and without Helicobacter pylori infection in gallbladder mucosa. [PDF]

PLoS ONE, 2013
BACKGROUND: Helicobacter pylori has been isolated from 10%-20% of human chronic cholecystitis specimens but the characteristics of "Helicobacter pylori positive cholecystitis" remains unclear.

Helicobacter pylori virulence factors in duodenal ulceration: A primary cause or a secondary infection causing chronicity [PDF]

, 2006
Reports from countries with a high prevalence of Helicobacter pylori. (H pylori) infection do not show a proportionately high prevalence of duodenal ulceration, suggesting the possibility that H pylori cannot be a primary cause of duodenal ulceration. It

Helicobacter pylori Membrane Vesicles Stimulate Innate Pro- and Anti-Inflammatory Responses and Induce Apoptosis in Jurkat T Cells [PDF]

, 2014
Persistent Helicobacter pylori infection induces chronic inflammation in the human gastric mucosa, which is associated with development of peptic ulceration, gastric atrophy, and gastric adenocarcinoma.

Serum proteomic profiling of precancerous gastric lesions and early gastric cancer reveals signatures associated with systemic inflammatory response and metaplastic differentiation

Frontiers in Molecular Biosciences
The noninvasive detection technique using serum for large-scale screening is useful for the early diagnosis of gastric cancer (GC). Herein, we employed liquid chromatography mass spectrometry to determine the serum proteome signatures and related ...

The Activity Reaction Core and Plasticity of Metabolic Networks [PDF]

PLoS Comput Biol 1, e68 (2005), 2006
Understanding the system level adaptive changes taking place in an organism in response to variations in the environment is a key issue of contemporary biology. Current modeling approaches such as the constraint-based flux balance analyses (FBA) have proved highly successful in analyzing the capabilities of cellular metabolism, including its capacity ...
