Over one‐third of cancer cases and two‐fifths of cancer deaths in southern China are preventable: Insights from the latest representative population‐based cancer registry data and risk factor survey

open access: yesInternational Journal of Cancer, Volume 158, Issue 4, Page 909-923, 15 February 2026.
What's new? This study quantified the cancer burden attributable to modifiable risk factors in Guangdong, the most populous and economically advanced province in southern China. By evaluating 15 modifiable risk factors, the study reveals that over one‐third of cancer cases and two‐fifths of cancer deaths in the region could potentially be prevented ...

Isospin in Reaction Dynamics. The Case of Dissipative Collisions at Fermi Energies

open access: yes, 2005
A key question in the physics of unstable nuclei is the knowledge of the $EOS$ for asymmetric nuclear matter ($ANM$) away from normal conditions. We recall that the symmetry energy at low densities has important effects on the neutron skin structure ...

Artemisia selengensis Leaves, a Vegetable Waste: LC‐MS‐Based Chemical Profiling, Ultrasound‐Assisted DES Extraction, and Xanthine Oxidase Inhibitory Activity

open access: yeseFood, Volume 7, Issue 1, February 2026.
This study focused on Artemisia selengensis leaves (ASL), a discarded agricultural waste. 72 compounds were identified by UPLC‐Q‐TOF‐MS. “Green” extraction with DES was optimized, and ASL's XO—inhibition was explored, presenting new ways for waste utilization. ABSTRACT Artemisia selengensis is a medicinal and edible plant, whose tender stems are widely

Is the incidence of early‐onset cancers increasing in the northeast of Italy? A 30‐year analysis of the regional cancer registration data by age, 1987–2019

open access: yesInternational Journal of Cancer, Volume 158, Issue 3, Page 532-545, 1 February 2026.
Whats New? This observational study of the incidence trends of malignancy by site, stratified by age group and sex, over three decades in a large northern Italian population reveals a heterogeneous landscape among younger adults (aged under 50). Invasive cutaneous melanoma in both sexes, testicular cancer and multiple myeloma in males, and breast ...

BF2 Complexes of N‐arylated 1‐amino‐anthraquinone, ‐xanthone, ‐thioxanthone, and Related Compounds: Synthesis and Properties

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 2, January 16, 2026.
Syntheses of BF2 complexes of 1‐(arylamino)anthraquinones and related compounds are developed and their properties studied. The physical properties of anthraquinones can be modulated by the introduction of arylamino groups next to the carbonyl function.
