Fast and Slow Precession of Gaseous Debris Disks Around Planet-Accreting White Dwarfs

open access: yes, 2018
Spectroscopic observations of some metal-rich white dwarfs (WDs), believed to be polluted by planetary material, reveal the presence of compact gaseous metallic disks orbiting them.

Compactifications of subvarieties of tori [PDF]

open access: yes, 2005
We study compactifications of subvarieties of algebraic tori defined by imposing a sufficiently fine polyhedral structure on their non-archimedean amoebas.

Asiatic Acid Ameliorates MNNG‐Induced Chronic Atrophic Gastritis by Inhibiting the Activation of the HRAS/PI3K/AKT/GSK3β Signaling Axis

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Chronic atrophic gastritis (CAG), a widespread gastrointestinal condition, is widely acknowledged as a precursor to gastric cancer (GC). The incidence of CAG has been steadily increasing, yet effective pharmacological interventions remain unavailable. Asiatic acid (AA), a bioactive triterpenoid isolated from Centella asiatica, has demonstrated

DNA polymerase B deficiency is linked to aggressive breast cancer: a comprehensive analysis of gene copy number, mRNA and protein expression in multiple cohorts [PDF]

open access: yes, 2014
Short arm of chromosome 8 is a hot spot for chromosomal breaks, losses and amplifications in breast cancer. Although such genetic changes may have phenotypic consequences, the identity of candidate gene(s) remains to be clearly defined.

Connecting Health Promotion and Sustainable Development Goals to Enhance the Health of Agrifood Temporary Migrant Workers—a Scoping Review

open access: yesSustainable Development, EarlyView.
ABSTRACT Temporary migrant workers (TMW) in the agrifood system face social determinants of health (SDoH) that contribute to health inequities. Despite their dual residency, the potential of the Sustainable Development Goals (SDG) to support the health of TMW remains underexamined.

Research on the Carrying Capacity of the Water Environment Based on System Dynamics of Nanjing City, China

open access: yesSafety Science and Technology, EarlyView.
The social and natural water circulation causal feedback relationship is established, and an SD model on water supply–demand and water ecological crisis is constructed. The GDP growth rate and the sewage treatment rate are identified as the key factors affecting the system.

Hormone resistance in non-atypical endometrial hyperplasia: role of PgR-A and PgR-B expression in predicting treatment response

open access: yesJournal of V. N. Karazin Kharkiv National University: Series Medicine
Background. Endometrial hyperplasia (EH) without atypia remains a significant clinical challenge due to a high recurrence rate following hormone therapy, reaching up to 64.7%.

Diflubenzuron Caused Mitochondrial Dysfunction, Ca2+ Homeostasis Disruption, and Intrinsic Apoptosis in Trophoblastic Cells

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Diflubenzuron is used as an insect growth inhibitor, and its potential risk to human health was raised owing to the possibility of environmental residues and human exposure. This study aimed to investigate the toxic mechanism of diflubenzuron on trophoblastic cells such as HTR8/SVneo and JEG‐3 cells. We investigated mitochondrial function, Ca2+

Oestrogen and Progesterone Receptors as Prognostic Variables in Hormonally Treated Breast Cancer

open access: yesThe International Journal of Biological Markers, 1996
This study directly compares ER status and PgR status of primary tumour tissue measured by enzyme immunoassays for prediction of response to therapy and survival in 99 women with breast cancer treated by hormone therapy.

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

open access: yesIntegrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.
