Inflammaging Markers in the Extremely Cold Climate: A Case Study of Yakutian Population.

Int J Mol Sci

December 2024

Artificial Intelligence Research Center, Institute of Information Technologies, Mathematics and Mechanics, Lobachevsky State University, 603022 Nizhny Novgorod, Russia.

Yakutia is one of the coldest permanently inhabited regions in the world, characterized by a subarctic climate with average January temperatures near -40 °C and the minimum below -60 °C. Recently, we demonstrated accelerated epigenetic aging of the Yakutian population in comparison to their Central Russian counterparts, residing in a considerably milder climate. In this paper, we analyzed these cohorts from the inflammaging perspective and addressed two hypotheses: a mismatch in the immunological profiles and accelerated inflammatory aging in Yakuts.

Despite treatment, prostate cancer commonly progresses into castration-resistant prostate cancer (CRPC), which remains largely incurable, requiring the development of new interventions. Darolutamide is an orally administered second-generation androgen receptor inhibitor indicated for patients with non-metastatic CRPC or metastatic hormone-sensitive prostate cancer. Here, we evaluated the effect of androgen receptor (AR) inhibition by darolutamide in combination with DNA double-strand-break-inducing targeted radium-223 alpha therapy in vitro and in an intratibial LNCaP xenograft model mimicking prostate cancer metastasized to bone.

Background/objectives: Rodents provide a useful translational model of fear- and anxiety-related behaviors. Previously stressed animals exhibit physiological and behavioral stress responses that parallel those observed in anxious humans. Patients diagnosed with post-traumatic stress disorder (PTSD) present with a spectrum of debilitating anxiety symptoms that result from exposure to one or more traumatic events, with individuals exposed to early adverse experiences and women having increased vulnerability for diagnoses; however, the mechanisms of this increased vulnerability remain unknown.

Anti-Graying Effects of External and Internal Treatments with Luteolin on Hair in Model Mice.

Antioxidants (Basel)

December 2024

Department of Occupational and Environmental Health, Nagoya University Graduate School of Medicine, 65 Tsurumai-cho, Showa-ku, Nagoya 466-8550, Japan.

Little is known about the anti-graying effects of antioxidants on hair. The anti-graying effects of three antioxidants (luteolin, hesperetin, and diosmetin) on hair were investigated according to the sequential processes of hair graying that were previously clarified in model mice [Ednrb(+/-);RET-mice]. External treatment with luteolin, but not that with hesperetin or diosmetin, alleviated hair graying in Ednrb(+/-);RET-mice.

Article Synopsis
  • Platelets play a critical role in blood clotting and the immune response, relying on a balanced relationship between their production and destruction influenced by reactive oxygen species (ROS).
  • Moderate levels of ROS enhance platelet production and function, aiding in processes like collagen binding and thrombus formation, but high levels can lead to platelet apoptosis and increased risk of thrombosis.
  • The review emphasizes the need for further research into specific ROS signaling pathways, which could lead to new therapies for platelet-related disorders by leveraging the beneficial aspects of ROS while managing their harmful effects.

Article Synopsis
  • Tandem duplications (TDs) in the UBTF gene are a recently identified genetic alteration linked to pediatric and adult acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), establishing UBTF-TD as a distinct subtype of AML.
  • A study of 27 pediatric patients revealed that UBTF-TD is commonly associated with symptoms like cytopenia and characteristic changes in bone marrow, such as erythroid hyperplasia and trilineage dysplasia.
  • The findings suggest that patients with MDS and AML exhibiting UBTF-TD have similar prognoses, indicating that both conditions may represent different manifestations of the same underlying disease.
