Association between visceral adiposity index and cancer risk in the UK Biobank cohort

Cancer, Volume 131, Issue 1, 1 January 2025.
ABSTRACT Background The visceral adiposity index (VAI) is a marker of visceral fat accumulation and metabolic dysfunction, but there is limited evidence of its association with cancer. The objective of this study was to investigate associations between the VAI and both incident cancer at 23 sites and all‐cause cancer.

Cell Death Mechanisms Produced by Carbon‐Based Nanoparticles

Journal of Nanotechnology, Volume 2025, Issue 1, 2025.
Using carbon‐based nanoparticles, such as diamond, graphite, fullerene, and nanotubes, has increased their research as possible strategies for drug delivery to control diseases, especially cancer. However, because these materials, when interacting with the living environment, release substances that are capable of inducing cell death by themselves, it ...

Cancer risk among people living with Human Immunodeficiency Virus (HIV) in Rwanda from 2007 to 2018

International Journal of Cancer, Volume 155, Issue 12, Page 2149-2158, 15 December 2024.
What's New? Understanding cancer risk among people living with HIV (PLHIV) is highly relevant for cancer control in sub‐Saharan Africa, where HIV burden is exceptionally high. The authors of this study utilized data from the Rwanda population‐based cancer registry to compare cancer incidence among PLHIV and HIV‐negative individuals. PLHIV accounted for

Analysis of the immunomodulatory properties of mycobacterium cell wall fraction on the cytokine production of peripheral blood mononuclear cells of healthy dogs

Veterinary Dermatology, Volume 35, Issue 6, Page 595-604, December 2024.
Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

Eine DNA‐Polymerase‐Variante erkennt den epigenetischen Marker 5‐Methylcytosin durch erhöhten Fehleinbau

Angewandte Chemie, Volume 136, Issue 48, November 25, 2024.
Entwicklung einer DNA‐Polymerase aus Thermus aquaticus, die methylierte von unmethylierter DNA durch einen erhöhten Fehleinbau gegenüber 5‐Methylcytosin (5 mC) während der DNA‐Synthese unterscheidet. Durch die Erzeugung von 5 mC‐abhängigen Mutationssignaturen im PCR‐Produkt ist das Enzym in der Lage, methylierte Stellen zu erkennen und ermöglicht den ...

A DNA Polymerase Variant Senses the Epigenetic Marker 5‐Methylcytosine by Increased Misincorporation

Angewandte Chemie International Edition, Volume 63, Issue 48, November 25, 2024.
Engineering of a Thermus aquaticus DNA polymerase that distinguishes methylated from unmethylated DNA by increased misincorporation opposite 5‐methylcytosine (5 mC) during DNA synthesis. By generating 5 mC‐dependent mutation signatures in the PCR product, the enzyme is able to sense methylated sites and allows direct detection by reading elevated error
